[0118] The following will be combined with the accompanying drawings to clearly and in detail describe the technical solutions in some embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0119] In optical communication technology, to establish information transmission between information processing devices, it is necessary to load the information onto light and use the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When transmitting optical signals within information transmission equipment, they can reduce optical power loss, thereby enabling high-speed, long-distance, and low-cost information transmission. The signals that information processing equipment can recognize and process are electrical signals. Information processing equipment typically includes optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and information transmission equipment typically includes optical fibers and optical waveguides.

[0120] Optical modules can convert optical signals into electrical signals between information processing devices and information transmission devices. For example, at least one of the optical signal input or output ends of an optical module is connected to an optical fiber, and at least one of the electrical signal input or output ends of the optical module is connected to an optical network terminal. A first optical signal from the optical fiber is transmitted to the optical module, which converts the first optical signal into a first electrical signal and transmits the first electrical signal to the optical network terminal. A second electrical signal from the optical network terminal is transmitted to the optical module, which converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber. Because multiple information processing devices can transmit information via electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, rather than all of them. Here, the information processing device directly connected to the optical module is referred to as the optical module's host computer. Furthermore, the optical signal input or output end of the optical module can be referred to as an optical port, and the electrical signal input or output end of the optical module can be referred to as an electrical port.

[0121] Figure 1 is a partial structural diagram of an optical communication system provided according to some embodiments of the present disclosure. As shown in Figure 1, the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100, an optical module 200, an optical fiber 101, and a network cable 103.

[0122] One end of optical fiber 101 extends toward remote information processing device 1000, and the other end of optical fiber 101 is connected to optical module 200 through the optical port of optical module 200. Optical signals can be totally reflected in optical fiber 101, and the propagation of the optical signal in the direction of total reflection can almost maintain the original optical power. The optical signal undergoes multiple total reflections in optical fiber 101 to transmit the optical signal from remote information processing device 1000 to optical module 200, and vice versa, thereby achieving long-distance, low-power information transmission.

[0123] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 may be detachably connected or fixedly connected to the optical module 200. The host computer 100 is configured to provide data signals to the optical module 200, receive data signals from the optical module 200, or monitor or control the operating status of the optical module 200.

[0124] The host computer 100 includes a substantially rectangular housing and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to connect to the optical module 200 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0125] The host computer 100 also includes an external electrical interface that can access an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to access a network cable 103 so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so that an electrical signal connection is established between the local information processing device 2000 and the host computer 100 via the network cable 103. For example, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 via the network cable 103. The host computer 100 generates a second electrical signal based on the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200. The optical module 200 converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber 101. The second optical signal is then transmitted to the remote information processing device 1000 via the optical fiber 101. For example, a first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101. The first optical signal from the optical fiber 101 is transmitted to the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal. The optical module 200 transmits the first electrical signal to the host computer 100. The host computer 100 generates a fourth electrical signal based on the first electrical signal and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that optical modules are tools for converting optical signals into electrical signals. During this conversion process, the information does not change, but the encoding and decoding methods of the information can change.

[0126] In addition to the optical network terminal, the host computer 100 also includes an optical line terminal (OLT), an optical network device (ONT), or a data center server.

[0127] Figure 2 is a partial structural diagram of a host computer according to some embodiments. To clearly illustrate the connection between the optical module 200 and the host computer 100, Figure 2 only shows the structure of the host computer 100 related to the optical module 200. As shown in Figure 2, the host computer 100 also includes a PCB circuit board 105 disposed within the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a heat sink 107 disposed on the cage 106, and an electrical connector disposed within the cage 106. The electrical connector is configured to connect to the electrical port of the optical module 200; the heat sink 107 has raised structures such as fins to increase the heat dissipation area.

[0128] The optical module 200 is inserted into the cage 106 of the host computer 100. The cage 106 secures the optical module 200. Heat generated by the optical module 200 is transferred to the cage 106 and then dissipated through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 connects with the electrical connector inside the cage 106, thereby establishing a bidirectional electrical signal connection between the optical module 200 and the host computer 100. Furthermore, the optical port of the optical module 200 connects to the optical fiber 101, thereby establishing a bidirectional optical signal connection between the optical module 200 and the optical fiber 101.

[0129] Figure 3 is a structural diagram of an optical module according to some embodiments of the present disclosure, and Figure 4 is an exploded view of an optical module according to some embodiments of the present disclosure; wherein the x-axis is the length of the optical module 200, the y-axis is the width of the optical module 200, and the z-axis is the height of the optical module 200. As shown in Figures 3 and 4, the optical module 200 includes a housing, a circuit board 300 disposed within the housing, a light emitting component 400, and a light receiving component 500. However, the present disclosure is not limited thereto; in some embodiments, the optical module 200 includes either the light emitting component 400 or the light receiving component 500.

[0130] The housing includes an upper housing 201 and a lower housing 202 . The upper housing 201 is assembled and connected to the lower housing 202 to form the housing having two openings 203 and 204 . The outer contour of the housing is generally a square.

[0131] In some embodiments, the lower shell 202 includes a base plate 2021 and lower side plates located on both sides of the base plate 2021 and arranged perpendicular to the base plate 2021; the upper shell 201 includes a cover plate 2011, which is covered on the two lower side plates of the lower shell 202 to form the above-mentioned shell.

[0132] In some embodiments, the lower shell 202 includes a base plate 2021 and a first lower side plate 2022 and a second lower side plate 2023 located on both sides of the base plate 2021 and perpendicular to the base plate 2021; the upper shell 201 includes a cover plate 2011 and a first upper side plate 2012 and a second upper side plate 2013 located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011. The first lower side plate 2022 and the second lower side plate 2023 are respectively connected to the first upper side plate 2012 and the second upper side plate 2013 to realize the assembly connection between the upper shell 201 and the lower shell 202.

[0133] The direction of the line connecting the two openings 203 and 204 can be consistent with the length of the optical module 200, or inconsistent with the length of the optical module 200. For example, opening 203 is located at the end of the optical module 200 (the right end in Figure 3), and opening 204 is also located at the end of the optical module 200 (the left end in Figure 3). Alternatively, opening 203 is located at the end of the optical module 200, while opening 204 is located on the side of the optical module 200. Opening 203 is an electrical port, from which the gold finger of the circuit board 300 extends and is inserted into the host computer (for example, the optical network terminal 100); opening 204 is an optical port, configured to receive the optical fiber 101, so that the optical fiber 101 is connected to the optical module 200.

[0134] The combined assembly of the upper housing 201 and the lower housing 202 facilitates installation of components such as the circuit board 300, the light emitting component 400, and the light receiving component 500 within the housing, with the upper housing 201 and the lower housing 202 providing encapsulation and protection for these components. Furthermore, during assembly of the circuit board 300, the light emitting component 400, and the light receiving component 500, the positioning components, heat dissipation components, and electromagnetic shielding components of these components are easily arranged, facilitating automated production.

[0135] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0136] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to achieve a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0137] For example, a locking member is provided on the lower housing 202 to secure the optical module 200 in the cage 106. An unlocking member 600 is provided on the lower housing 202. When the unlocking member 600 is pulled, the unlocking member 600 moves, changing the connection between the locking member and the host computer, thereby releasing the optical module 200 from the host computer, thereby allowing the optical module 200 to be removed from the cage 106.

[0138] The circuit board 300 includes circuit traces, electronic components, and chips. The circuit traces connect the electronic components and chips together according to the circuit design to achieve functions such as power supply, electrical signal transmission, and grounding. Electronic components include, for example, capacitors, resistors, transistors, and metal-oxide-semiconductor field-effect transistors (MOSFETs). Chips include, for example, lasers, photodetectors, microcontroller units (MCUs), laser driver chips, limiting amplifiers (LAs), clock and data recovery (CDR) chips, power management chips, and digital signal processing (DSP) chips.

[0139] The circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also realize the load-bearing function.

The gold finger can be set only on the surface of one side of the circuit board 300 (for example, the upper surface shown in Figure 4), or it can be set on the upper and lower surfaces of the circuit board 300 to provide a larger number of pins, thereby adapting to occasions where a large number of pins are required. The gold finger is configured to establish an electrical connection with the host computer to achieve power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, data signal transmission, etc. Of course, flexible circuit boards are also used in some optical modules. Flexible circuit boards are generally used in conjunction with rigid circuit boards to supplement rigid circuit boards.

[0141] In some embodiments, the light emitting component 400 and the light receiving component 500 are physically separated from the circuit board 300 and then electrically connected to the circuit board 300 via corresponding flexible circuit boards or electrical connectors.

[0191] In some embodiments, the inner sidewall of the lower housing 202 is provided with an assembly slot 2027. The assembly slots 2027 are distributed on the inner sidewall of the first lower side plate 2022 and the inner sidewall of the second lower side plate 2023. The assembly slots 2027 are located between the first support platform 2025 and the support plate 2024. The assembly slots 2027 are used to attach and connect a shielding sheet, which is used for electromagnetic shielding at the optical port of the optical module 200.

[0192] Figure 16 is a schematic diagram of the assembly of a lower housing and an unlocking component according to some embodiments of the present disclosure, Figure 17 is a partial enlarged view of point B in Figure 16, Figure 18 is a partial schematic diagram of an optical module according to some embodiments of the present disclosure, and Figure 19 is a partial schematic diagram of an optical module according to some embodiments of the present disclosure. Figure 18 shows the assembly of the assembly portion 630 and the unlocking portion 640 with the lower housing 202 when the unlocking component 600 is in the initial state.

[0193] As shown in Figures 16 to 19, along the x direction, the unlocking component 600 is assembled to the lower shell 202, so that the second assembly column 6313 and the first assembly column 6311 are assembled to the first assembly cavity 2410, and the fourth assembly column 6323 and the third assembly column 6321 are assembled to the second assembly cavity 2420, and the first assembly protrusion 6312 is located in the first limiting hole 2413 and the second assembly protrusion 6322 is located in the second limiting hole 2423. The first assembly cavity 2410 and the second assembly cavity 2420 cooperate to assemble the assembly body 630a onto the support plate 2024, with the support surface 240 supporting the bottom of the assembly body 630a. The first and second stop plates 241 and 242 secure the assembly body 630a in the y-axis direction. The first, second, fourth, and fifth stop plates 2411, 2412, 2421, and 2422 secure the assembly body 630a in the z-axis direction. The first and second stop holes 2413 and 2423 allow the assembly body 630a to move back and forth along the x-axis within a preset range. The third and sixth stop plates 2414 and 2424 are used to limit the assembly body 630a to its maximum rightward position along the x-axis. The right sides of the first and fourth stop plates 2411 and 2421 are used to limit the assembly body 630a to its maximum leftward position along the x-axis.

[0194] The spring 650 is installed into the receiving groove 636 from the mounting hole 633, with one end of the spring 650 abutting against the first limit block 246 and the other end of the spring 650 embedded in the second limit block 634. In some embodiments, the spring 650 is always in a compressed state so that the spring 650 applies a thrust to the assembly body 630a.

[0195] Figure 20 is a schematic diagram illustrating the assembly of an optical module and a cage according to some embodiments of the present disclosure, and Figure 21 is a third partial schematic diagram of an optical module according to some embodiments of the present disclosure. Figure 21 illustrates the assembly portion 630 and the unlocking portion 640 with the lower housing 202 when the unlocking component 600 unlocks the optical module and the cage 106. As shown in Figures 20 and 21, when the optical module 200 is securely connected to the cage 106, the locking spring 1061 on the cage 106 engages the engaging component 243, and the locking spring 1061 is positioned above the unlocking portion 640. When the connection between the optical module 200 and the cage 106 needs to be released, the gripping portion 610 is pulled, causing the unlocking component 600 to move in the opposite direction of the x-axis. The assembly portion 630 then drives the unlocking component 640 to move. The first unlocking surface 2451 contacts the first support 643 and raises the first support 643 as the unlocking component 640 moves. The second unlocking surface 2452 contacts the second support 644 and raises the second support 644 as the unlocking component 640 moves. The unlocking body 641 bends, and the first and second supports 643 and 644 support the locking spring 1061. When the first and second supports 643 and 644 are raised to a certain extent, they directly lift the locking spring 1061, releasing the engagement between the locking spring 1061 and the engaging portion 243, thereby releasing the connection between the optical module 200 and the cage 106.

[0196] Figure 22 is a schematic diagram (I) of the structure of a shielding sheet provided according to some embodiments of the present disclosure, and Figure 23 is a schematic diagram (II) of the structure of a shielding sheet provided according to some embodiments of the present disclosure. As shown in Figures 22 and 23, the shielding sheet 700 includes a shielding sheet body 710, a first pressing portion 720, and a second pressing portion 730. The first pressing portion 720 and the second pressing portion 730 are respectively connected to the top of the shielding sheet body 710. A gap is formed between the first pressing portion 720 and the second pressing portion 730. The shielding sheet 700 is assembled to the optical port of the optical module 200. The shielding sheet body 710 is used to connect the light emitting component 400 and the light receiving component 500. The upper housing 201 presses against the first pressing portion 720 and the second pressing portion 730 to secure the shielding sheet 700. The shielding sheet 700 electromagnetically shields the optical port of the optical module 200, thereby reducing the entry and exit of electromagnetic radiation from the optical port of the optical module 200.

[0197] The shielding sheet body 710 is provided with a first through-hole 711 and a second through-hole 712. Elastic bends 713 are provided on the sides of the shielding sheet body 710. For example, multiple elastic bends 713 are provided on the top, left, and right edges of the shielding sheet body 710. The first through-hole 711 is used for attaching and connecting the first fiber optic adapter 410, and the second through-hole 712 is used for attaching and connecting the second fiber optic adapter 510. The elastic bends 713 and the first holding portion 720 are located on the same side of the shielding sheet body 710.

[0198] The first pressing portion 720 is provided with a first pressing spring 721, which tilts away from the shielding sheet body 710. The first pressing spring 721 is used to increase the extrusion elasticity of the first pressing portion 720, facilitating the upper housing 201 to apply force to the first pressing portion 720. The second pressing portion 730 is provided with a second pressing spring 731, which tilts away from the shielding sheet body 710. The second pressing spring 731 is used to increase the extrusion elasticity of the second pressing portion 730, facilitating the upper housing 201 to apply force to the second pressing portion 730.

[0199] In some embodiments, a center seam 714 is defined between the first through hole 711 and the second through hole 712 , and a first bend 715 and a second bend 716 are defined in the center seam 714 . The first bend 715 and the second bend 716 are located on the same side of the shielding sheet body 710 as the elastic bend 713 .

[0200] Figure 24 is a schematic diagram (I) of a fixing plate according to some embodiments of the present disclosure, and Figure 25 is a schematic diagram (II) of a fixing plate according to some embodiments of the present disclosure. As shown in Figures 24 and 25, the fixing plate 800 includes a first fixing portion 810, a bridging portion 820, and a second fixing portion 830. One end of the bridging portion 820 connects to the top of the first fixing portion 810, and the other end of the bridging portion 820 connects to the top of the second fixing portion 830. The second surface of the first fixing portion 810 faces the first surface of the second fixing portion 830, and the first surface of the first fixing portion 810 faces away from the second fixing portion 830, while the second surface of the second fixing portion 830 faces away from the first fixing portion 810. In some embodiments, the first fixing portion 810 and the second fixing portion 830 are parallel or approximately parallel, with a third gap formed between them. The first fixing portion 810 and the second fixing portion 830 are used to compress and secure the first and second fiber optic adapters 410 and 510, with the upper housing 201 compressing and contacting the bridging portion 820. Applying opposite forces on the first fixing portion 810 and the second fixing portion 830 can move the first fixing portion 810 and the second fixing portion 830 closer together, reduce the third interval, and generate a reaction force that moves the first fixing portion 810 and the second fixing portion 830 away from each other.

[0201] In some embodiments, the second fixing portion 830 is provided with a first assembly notch 831 and a second assembly notch 832 . The first assembly notch 831 is used for assembling and connecting the first optical fiber adapter 410 , and the second assembly notch 832 is used for assembling and connecting the second optical fiber adapter 510 .

[0202] In some embodiments, the first fixing portion 810 is smaller than the second fixing portion 830. This helps save material for the fixing plate 800 while ensuring the required strength for connecting the first fiber optic adapter 410 and the second fiber optic adapter 510. Furthermore, this also facilitates assembly. In some embodiments, support portions 821 are provided on each side edge of the bridge portion 820, and the lower housing 202 supports and connects to the support portions 821.

[0203] Figure 26 is a schematic diagram of the internal structure of an optical module according to some embodiments of the present disclosure. As shown in Figure 26, a first fiber optic adapter 410 includes a first fiber optic adapter body 411, and a first stop 412 and a second stop 413 disposed on the first fiber optic adapter body 411, with a first gap formed between the first stop 412 and the second stop 413. A second fiber optic adapter 420 includes a second fiber optic adapter body 511, and a third stop 512 and a fourth stop 513 disposed on the second fiber optic adapter body 511, with a fourth gap formed between the third stop 512 and the fourth stop 513.

[0204] Figure 27 is an exploded schematic diagram of another optical module provided according to some embodiments of the present disclosure, and Figure 28 is a cross-sectional view of an optical module provided according to some embodiments of the present disclosure, with Figure 28 being a partial enlarged view of point C in Figure 27 . As shown in Figures 27-29 , both sides of the shielding plate 700 are located within the assembly groove 2027, the first fiber optic adapter body 411 is embedded in and connected to the first through-hole 711, and the second fiber optic adapter body 511 is embedded in and connected to the second through-hole 712. The elastic bends 713 on the left and right edges of the shielding plate body 710 press against the sidewalls of the assembly groove 2027, causing the side surfaces of the shielding plate body 710 to contact the side surfaces connecting the first and third stop platforms 412, 512, thereby increasing the extrusive contact force between the shielding plate body 710 and the first and third stop platforms 412, 512. When the upper shell 201 is installed on the lower shell 202 against the x-axis direction, the upper shell 201 squeezes the elastic bend 713, the first pressing portion 720 and the second pressing portion 730 at the top of the shielding sheet body 710, so that the shielding sheet body 710 is in full contact with the first stop 412, the third stop 512, the upper shell 201 and the lower shell 202, thereby ensuring the shielding effect of the shielding sheet 700.

[0205] In some embodiments, the upper housing 201 further includes a third upper side plate 2014 and a fourth upper side plate 2015. The side edge of the third upper side plate 2014 is connected to the lower portion of the first upper side plate 2012b, and the side edge of the fourth upper side plate 2015 is connected to the lower portion of the second upper side plate 2013b. The third upper side plate 2014 and the fourth upper side plate 2015 are located below the cover plate 2011. When the upper housing 201 is assembled and connected to the lower housing 202, the third upper side plate 2014 and the fourth upper side plate 2015 contact the bottom surface of the connection base plate 2021.

[0206] In some embodiments, a first connecting seat 2016 and a second connecting seat 2017 are provided at one end of the cover plate 2011, and a first mounting slot 2415 and a second mounting slot 2425 are provided on the lower housing 202. The first connecting seat 2016 is screwed to the first mounting slot 2415, and the second connecting seat 2017 is screwed to the second mounting slot 2425. For example, the first mounting slot 2415 is provided at the outer end of the first baffle plate 241 and the outer end of the third limiting plate 2414, and the second mounting slot 2425 is provided at the outer end of the second baffle plate 242 and the outer end of the sixth limiting plate 2424.

[0207] The first support platform 2025 supports the first fiber optic adapter body 411, and the second support platform 2026 supports the second fiber optic adapter body 511. The first assembly notch 831 is assembled and connected to the first fiber optic adapter body 411, and the second assembly notch 832 is assembled and connected to the second fiber optic adapter body 511. The first fixing portion 810 squeezes the first fiber optic adapter body 411 and the second fiber optic adapter body 511, and the second fixing portion 830 squeezes the first fiber optic adapter body 411 and the second fiber optic adapter body 511. In some embodiments, the first surface of the first fixing portion 810 presses and contacts the side surfaces of the first stop 412 and the third stop 512, and the second surface of the second fixing portion 830 presses and contacts the second stop 413 and the fourth stop 513, so that the fixing piece 800 is embedded in the first and second gaps, thereby more firmly fixing the first and second fiber optic adapters 410 and 510 and preventing the first and second fiber optic adapters 410 and 510 from shaking or moving within the housing.

[0208] FIG30 is a schematic diagram of the structure of the unlocking component and the lower shell in the optical module according to an embodiment of the present disclosure, and FIG31 is a schematic diagram of the exploded structure of the unlocking component and the lower shell in the optical module according to an embodiment of the present disclosure. Referring to FIG30 and FIG31, in order to facilitate the installation of the optical transceiver component and the circuit board and improve the compactness of the optical module structure, in some examples of the embodiments of the present disclosure, the lower shell 202 includes: a first wall 2021a and a second wall 2022a. The second wall 2022a is connected to one end of the first wall 2021a, and the second wall 2022a is recessed in the first wall 2021a. In the embodiments of the present disclosure, the locking portion 20221 (in some examples, it can also be called a locking component) can be provided on the second wall 2022a.

[0209] In some examples, it can also be understood that the first wall 2021a protrudes from the second wall 2022a, that is, one end of the lower shell 202 is thicker than the other end; in this way, the optical transceiver component can be set at the thicker end, for example, on the inner side of the first wall 2021a, and the circuit board itself is thinner and occupies less space, and can be set on the inner side of the second wall 2022a; in this way, the circuit board in the optical module has a compact structure in the shell; when connected to the upper computer, the second wall 2022a can be inserted into the upper computer, so that the space required to occupy the upper computer is relatively small.

[0210] In some optional examples of the embodiments of the present disclosure, the first wall 2021a and the second wall 2022a can be integrally formed, for example, they can be cast in one piece. The locking portion 20221 can be a protrusion on the second wall 2022a. In some examples, the locking portion 20221 and the second wall 2022a can also be integrally formed. As an optional example, the side of the locking portion 20221 facing away from the first wall 2021a (i.e., the side of the locking portion 20221 facing the upper computer during the insertion of the optical module into the upper computer) can be an inclined wall 20222. This makes it easier for the locking structure on the upper computer to pass over the locking portion 20221 and be engaged with the side of the locking portion 20221 facing the first wall 2021a, thereby improving the smoothness of the insertion of the optical module into the upper computer.

[0211] In some examples of the embodiments of the present disclosure, the unlocking component 600 can be movably arranged on the lower shell 202 along the length direction of the lower shell 202 (for example, the direction shown by the x-axis in Figure 6), and the unlocking component 600 extends from the first wall 2021a to the second wall 2022a. In some examples, the unlocking component 600 can be a sheet metal part, that is, the unlocking component 600 can also be made of a metal material. In the embodiments of the present disclosure, the unlocking component 600 includes a body 601 (in some examples, the connecting portion can include the body 601), a push member 602 (in some examples, the assembly portion can include the push member 602), and a force member 603 (in some examples, the unlocking portion can include the force member 603).

[0212] In some examples, the body 601 can be disposed on the first wall 2021a. In some optional examples, a limiting groove can be disposed along the length of the first wall 2021a, and the body 601 can be disposed within the limiting groove and move along the limiting groove. In other examples, a limiting ridge can also be disposed along the length of the first wall 2021a. Two limiting ridges can be provided, and the two limiting ridges can be spaced apart along the width direction of the lower housing 202 (e.g., the direction shown by the y-axis in FIG6 ). The body 601 can be disposed within the gap between the two limiting ridges and move along the groove defined by the two limiting ridges.

[0213] In some examples of the embodiments of the present disclosure, the ejector 602 is connected to one end of the body 601 facing the second wall 2022a, and the ejector 602 is tilted relative to the body 601 toward the second wall 2022a. The ejector 602 may extend from the end of the body 601 toward the second wall 2022a, and the ejector 602 extends along the height direction of the lower housing 202 (e.g., the direction indicated by the negative z-axis in FIG6 ), thereby causing the ejector 602 to be tilted relative to the body 601. It will be understood that in some examples of the embodiments of the present disclosure, the unlocking component 600 may be a sheet metal component. Therefore, in some examples, the ejector 602 may be formed by bending the end of the unlocking component 600 facing the second wall 2022a. In other words, the ejector 602 and the body 601 may be an integral structure. This facilitates the processing and production of the unlocking component 600, saving processing and production costs.

[0214] In some examples, the body 601, the ejection member 602, and the force-applying member 603 are integrally formed, wherein the force-applying member 603 may be formed by bending the end of the ejection member 602 facing the second wall 2022a. In other words, in the disclosed embodiments, the body 601 and the force-applying member 603 may be two parallel parts, and the ejection member 602 may be an inclined wall connected between the body 601 and the force-applying member 603.

[0215] In order to limit the unlocking component 600 to the lower shell 202, the optical module provided in the embodiment of the present disclosure also includes an outer cover plate 700 (in some examples, the assembly mechanism may include an outer cover plate 700), which is covered on the first wall 2021a and is located on the side of the unlocking component 600 facing away from the lower shell 202; for example, the outer cover plate 700 can be covered on the lower side wall of the lower shell 202.

[0216] In some embodiments of the present disclosure, a clearance is provided between the outer cover 700 and the lower housing 202 to allow the unlocking member 600 to move. In some examples, the clearance can be the distance between the outer cover 700 and the bottom wall of the retaining groove. In other words, the unlocking member 600 moves between the bottom wall of the retaining groove and the inner wall of the outer cover 700.

[0217] Figure 32 is a structural schematic diagram of the lower housing in the optical module provided according to an embodiment of the present disclosure, Figure 33 is a partial enlarged view of point A in Figure 32, Figure 34 is another structural schematic diagram of the lower housing in the optical module provided according to an embodiment of the present disclosure, and Figure 35 is a structural schematic diagram of the lower housing and the unlocking member in the optical module provided according to an embodiment of the present disclosure. Referring to Figures 32-35, in some examples of the present disclosure, the lower housing 202 also includes a third wall 2023a, which is connected between the first wall 2021a and the second wall 2022a, and the third wall 2023a is used to abut against the upper computer housing. In some embodiments, the third wall 2023a can be a stepped surface between the first wall 2021a and the second wall 2022a.

[0218] In some examples, the first wall 2021a includes a first bottom plate 20211, a first side plate 20212, and a second side plate 20213. The first side plate 20212 and the second side plate 20213 are disposed on opposite sides of the first bottom plate 20211. In some embodiments of the present disclosure, the outer surface of the first bottom plate 20211 is provided with a first recessed portion 20214 and a second recessed portion 20215. The second recessed portion 20215 is recessed within the first recessed portion 20214 and extends through the third wall 2023a. The unlocking member is disposed within the second recessed portion 20215. In some examples, the first recessed portion 20214 can be located in the middle of the first recessed portion 20214 along the width direction of the first bottom plate 20211, and the second recessed portion 20215 is connected to the first recessed portion 20214. In some embodiments of the present disclosure, the unlocking component is disposed within the second recessed portion 20215. In other words, in the embodiments of the present disclosure, the unlocking component is positioned by the second recessed portion 20215. The width of the second recessed portion 20215 can be adapted to the width of the unlocking component. For example, the width of the second recessed portion 20215 can be equal to or similar to the width of the unlocking component. In some examples of the embodiments of the present disclosure, the body 601 can be located within the second recessed portion 20215.

[0219] In some embodiments, the first recessed portion 20214 includes a first sub-recessed portion 2141 and a second sub-recessed portion 2142. The first sub-recessed portion 2141 is connected to the second recessed portion 20215. The second sub-recessed portion 2142 extends to the third wall surface 2023a. The second sub-recessed portion 2142 is connected to the first sub-recessed portion 2141, the second recessed portion 20215, and the third wall surface 2023a. In other words, the first recessed portion 20214 can be shaped like a "convex" character, with the second sub-recessed portion 2142 located between the first sub-recessed portion 2141 and the second wall surface 2022a.

[0220] In some examples of the disclosed embodiments, the second recessed portion 20215 includes a first bottom wall 2151 and an ejection wall 2152. The first bottom wall 2151 protrudes from the second wall 2022a; that is, there is still a certain height difference between the first bottom wall 2151 and the second wall 2022a. The ejection wall 2152 is connected between the first bottom wall 2151 and the second wall 2022a and is inclined. The inclination of the ejection wall 2152 can be the same as or similar to the inclination of the ejection member 602. In some specific examples, the ejection wall 2152 can be formed by chamfering the portion of the third wall 2023a between the first wall 2021a and the second wall 2022a (for example, by cutting off the right-angled edge formed by the second recessed portion 20215 extending through the third wall 2023a).

[0221] Alternatively, in some examples, it can also be understood that a slope is formed between the first bottom wall surface 2151 and the second wall surface 2022a, and the first bottom wall surface 2151 and the second bottom wall surface 2156 are transitioned through the slope.

[0222] In some optional examples, the push-up wall surface 2152 can be a straight wall surface; in other optional examples, the push-up wall surface 2152 can also be a curved wall surface. It is understood that when the push-up wall surface 2152 is a curved wall surface, the curved wall surface can be an outwardly convex curved surface. In the embodiments disclosed herein, the push-up wall surface 2152 is a straight wall surface as an example for description.

[0223] In some examples, a first angle is defined between the ejection wall 2152 and the second wall 2022a, and a second angle is defined between the ejection member 602 and the second wall 2022a; wherein the first angle is greater than the second angle, so that when the unlocking member 600 moves toward the first wall 2021a, one end of the ejection member 602 facing the second wall 2022a abuts against the ejection wall 2152.

[0224] In some optional examples, the first angle may be 150°-160°, for example, the first angle may be 150°, 155°, or 160°. The second angle may be 135°-150°, for example, the first angle may be 135°, 140°, 145°, or 150°.

[0225] It should be noted here that the numerical values ​​and numerical ranges involved in the embodiments of the present disclosure are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors. Those skilled in the art may consider this part of the error to be negligible.

[0226] In the embodiment of the present disclosure, the first angle between the ejection wall 2152 and the second wall 2022a is set to be greater than the second angle between the ejection member 602 and the second wall 2022a; thus, when the unlocking component 600 moves toward the first wall 2021a, only the end of the ejection member 602 facing the lower housing 202 contacts the ejection wall 2152. In other words, there is line-surface contact between the ejection member 602 and the ejection wall 2152. This effectively avoids movement resistance and jitter caused by unevenness of the ejection wall 2152 or the ejection member 602, thereby improving the stability of the unlocking component in unlocking the optical module. In some examples of the present disclosure, a limiting post 2153 is provided on the first bottom wall 2151; wherein the limiting post 2153 protrudes from the first bottom wall 2151. An accommodating through-hole 6011 is provided on the unlocking component, and a limiting column 2153 is provided in the accommodating through-hole 6011, and the limiting column 2153 is located at the end of the accommodating through-hole 6011 facing away from the second wall surface 2022a; a positioning column 6012 is provided at the end of the accommodating through-hole 6011 facing the second wall surface 2022a; in some embodiments of the present disclosure, a reset member 607 is provided in the accommodating through-hole 6011, one end of the reset member 607 is connected to the positioning column 6012, and the other end of the reset member 607 is connected to the limiting column 2153; when the unlocking component moves away from the second wall surface 2022a, the reset member 607 provides a reset force facing the second wall surface 2022a to the unlocking component, so that when the external force on the unlocking component disappears, the reset member 607 drives the unlocking component to move toward the second wall surface 2022a.

[0227] The receiving hole 6011 can be obtained by drilling or slotting a sheet metal part. In some examples of the embodiments of the present disclosure, the reset member 607 can be an elastic component such as a spring or a sponge column, one end of which abuts against the limiting column 2153, and the elastic component extends along the extension direction of the receiving hole 6011, and the other end of the elastic component is connected to the positioning column 6012. In this way, when the unlocking component moves toward the first wall 2021a, the reset member 607 is compressed, thereby storing force; when the external force acting on the unlocking component disappears, the stored force of the reset member 607 is released, thereby pushing the unlocking component to move toward the second wall 2022a.

[0228] In some examples, the reset member 607 can also be two magnets with the same poles facing each other, one of which is set on the limit column 2153, and the other is set on the positioning column 6012. When the unlocking component moves toward the first wall 2021a, the distance between the two magnets with the same poles facing each other decreases and the repulsive force increases. When the external force on the unlocking component disappears, the repulsive force between the two magnets is released, thereby pushing the unlocking component to move toward the second wall 2022a.

[0229] In the embodiment of the present disclosure, a receiving hole 6011 is provided on the unlocking component, and a limiting column 2153 is provided on the first bottom wall 2151. The limiting column 2153 is passed through the receiving hole 6011, and the limiting column 2153 is located at the end of the receiving hole 6011 facing away from the second wall 2022a. In this way, when the reset member 607 is provided, the reset member 607 can be accommodated in the receiving hole 6011, which can reduce the space size required to be occupied by the reset member 607, thereby facilitating the miniaturization of the optical module. In addition, the limiting column 2153 is set at the end of the accommodating through-hole 6011 facing away from the second wall surface 2022a, and the positioning column 6012 is set at the end of the accommodating through-hole 6011 facing the second wall surface 2022a. In this way, one end of the reset member 607 only needs to be sleeved on the outer periphery of the positioning column 6012, and the other end of the reset member 607 can be pressed against the limiting column 2153, which facilitates the installation of the reset member 607 and improves the assembly efficiency of the optical module.

[0230] In some other examples of the embodiments of the present disclosure, the second recessed portion 20215 further has a first limiting wall 2154 and a second limiting wall 2155, and the first limiting wall 2154 and the second limiting wall 2155 are relatively arranged on both sides of the first bottom wall 2151 along the width direction, and the first limiting wall 2154 is recessed to form a first limiting groove 21541, and the first sub-bottom wall 21542 of the first limiting groove 21541 is recessed in the first bottom wall 2151; the second limiting wall 2155 is recessed to form a second limiting groove 21551, and the second sub-bottom wall 21552 of the second limiting groove 21551 is recessed in the first bottom wall 2151; the first limiting groove 21541 and the second limiting groove 21551 are located on both sides of the limiting column 2153; the main body 601 is limited between the first limiting wall and the second limiting wall.

[0231] The first limiting groove 21541 and the second limiting groove 21551 can be arranged opposite each other, wherein the width between the side walls of the first limiting groove 21541 and the second limiting groove 21551 is greater than the width between the first limiting wall 2154 and the second limiting wall 2155. As an alternative example, the width between the first limiting wall 2154 and the second limiting wall 2155 can be adapted to the width of the body 601. Of course, in some examples, the widths of the body 601, the ejecting member 602, and the force applying member 603 can be the same to facilitate movement of the unlocking member 600 within the second recess 20215.

[0232] In some optional examples of the disclosed embodiments, a third recessed portion 2121 is provided on the outer surface of the first side plate 20212, and a fourth recessed portion 2131 is provided on the surface of the second side plate 20213. The third recessed portion 2121 is recessed to form a plurality of first latching slots 21211 arranged side by side, and the fourth recessed portion 2131 is recessed to form a plurality of second latching slots 21311 arranged side by side. The third recessed portion 2121 is connected to the first recessed portion 20214, and the fourth recessed portion 2131 is also connected to the first recessed portion 20214.

[0233] In some embodiments of the present disclosure, the first card slot 21211 can be formed by punching the side wall of the third recessed portion 2121 inwardly. The first card slot 21211 can be provided with two, three, or four, etc. In the embodiments of the present disclosure, there is no limit on the number of first card slots 21211. Among them, the setting method of the second card slot 21311 can be the same as or similar to that of the first card slot 21211, and this will not be repeated in the embodiments of the present disclosure. In some examples, the second card slot 21311 can be symmetrically arranged with the first card slot 21211. In this way, the positioning process when setting the first card slot 21211 and the second card slot 21311 can be reduced, thereby improving processing efficiency.

[0234] In some other optional examples of the embodiments of the present disclosure, the second recessed portion 20215 further has a second bottom wall 2156, a third limiting wall 2157 and a fourth limiting wall 2158, the second bottom wall 2156 is located at the end of the first bottom wall 2151 facing away from the second wall 2022a, and the second bottom wall 2156 is recessed in the first bottom wall 2151; the third limiting wall 2157 and the fourth limiting wall 2158 are located on both sides of the second bottom wall 2156 along the width direction of the second bottom wall 2156, the third limiting wall 2157 is recessed in the first limiting wall 2154, and the fourth limiting wall 2158 is recessed in the second limiting wall 2155. That is to say, there is a certain height difference between the second bottom wall 2156 and the first bottom wall 2151 , and the width between the third limiting wall 2157 and the fourth limiting wall 2158 is greater than the width between the first limiting wall 2154 and the second limiting wall 2155 .

[0235] In some examples, a transition slope 2159 is defined between the second bottom wall 2156 and the first bottom wall 2151. In other words, the transition slope 2159 is not perpendicular to either the first or second bottom wall 2151, 2156. This reduces the effect of the height difference between the first and second bottom walls 2151, 2156 on the movement of the rubber-coated handle, effectively improving the smooth movement of the unlocking component within the second recess 20215.

[0236] To ensure that when the unlocking component is in the reset state, that is, the optical module and the upper computer are in the locked state, the force-applying member 603 is located between the second wall 2022a and the locking spring of the upper computer, and at the same time reduce the overall size of the optical module, in some embodiments of the present disclosure, along the width direction of the lower shell 202, sinking grooves 20223 are provided on both sides of the locking part 20221, and the sinking grooves 20223 are recessed in the second wall 2022a, and the side wall of the sinking groove 20223 facing the first wall 2021a is a sloped wall 20224. In some examples, when the unlocking component 600 is in the reset state, the force-applying member 603 can sink into the sinking groove 20223.

[0237] By setting a sunken groove 20223 on both sides of the locking part 20221, the sunken groove 20223 is recessed in the second wall 2022a; in this way, when the unlocking component is in the reset state, the fourth bending portion sinks into the sunken groove 20223, so that the force-applying member 603 is fitted on the second wall 2022a as a whole, which can reduce the gap between the force-applying member 603 and the second wall 2022a, thereby reducing the gap between the locking spring of the upper computer and the second wall 2022a, thereby improving the stability of the locking between the optical module and the upper computer.

[0238] In some embodiments of the present disclosure, the sloped wall 20224 is not perpendicular to the second wall 2022a and the bottom wall of the sinking groove 20223. In this way, a sloped wall 20224 is formed on the side of the sinking groove 20223 facing the first wall 2021a. When the unlocking component 600 moves toward the first wall 2021a, the force-applying member 603 moves from the inside to the outside of the sinking groove 20223 along the sloped wall 20224, which can reduce the movement resistance of the force-applying member 603 and improve the smoothness of the movement of the unlocking component 600.

[0239] In some examples, the inclined wall surface may be a straight inclined surface; or, in other examples, the sloped wall surface 20224 may also be an outwardly convex arc-shaped wall surface. The embodiments of the present disclosure do not limit the type of the inclined wall surface.

[0240] Figure 36 is a schematic diagram of one structure of the unlocking component in an optical module according to an embodiment of the present disclosure, and Figure 37 is a schematic diagram of another structure of the unlocking component in an optical module according to an embodiment of the present disclosure. To prevent the unlocking component 600 from being pulled out of the movable gap between the lower housing and the outer cover under the action of external forces, as shown in Figures 35-37, the unlocking component 600 in this embodiment of the present disclosure further includes: a first limiting arm 604 and a second limiting arm 605.

[0241] The first limiting arm 604 protrudes from the main body 601, and the first limiting arm 604 is located on the side of the accommodating through hole 6011. The first limiting arm 604 includes a first limiting extension arm 6041 and a first limiting bending arm 6042. The first limiting extension arm 6041 extends along the width direction of the main body 601 into the first limiting groove, and the first limiting bending arm 6042 bends toward the first sub-bottom wall.

[0242] In some embodiments of the present disclosure, the dimension of the first limiting arm 604 along the length direction of the main body 601 is smaller than the dimension of the first limiting groove along the length direction of the second recessed portion, so that the first limiting arm 604 can move along the length direction in the first limiting groove.

[0243] In some embodiments of the present disclosure, the first limiting arm 604 is set on the side of the accommodating through-hole 6011 , so that the first limiting arm 604 can widen the body 601 on the side of the accommodating through-hole 6011 , thereby enhancing the strength of the body 601 .

[0244] In some examples of the embodiments of the present disclosure, part of the first limiting arm 604 can be bent toward the lower shell body 202 to form a first limiting extension arm 6041 and a first limiting bending arm 6042; in this way, the size of the first limiting arm 604 along the thickness direction of the main body 601 can be increased. When limiting the unlocking component 600, the first limiting bending arm 6042 can be blocked on the side wall of the first limiting groove facing away from the second wall, so that the size of the first limiting arm 604 along the thickness direction of the main body 601 is larger than the gap between the first sub-recess and the outer cover plate, which can avoid pulling the unlocking component 600 over. In addition, the size of the first limiting arm 604 along the thickness direction of the main body 601 is increased. In this way, when the unlocking component 600 is limited, the force-bearing area of ​​the first limiting arm 604 along the thickness direction of the main body 601 is increased, thereby improving the stability of the main body 601 in the thickness direction; when the main body 601 swings in the thickness direction, the first limiting bending arm 6042 can abut against the first sub-bottom wall surface, thereby improving the unlocking stability of the unlocking component 600.

[0245] It is understood that in the embodiment of the present disclosure, the second limiting arm 605 protrudes from the body 601 and is located on the other side of the accommodating through-hole 6011. The second limiting arm 605 includes a second limiting extension arm 6051 and a second limiting bent arm 6052. The second limiting extension arm 6051 extends along the width direction of the body 601 into the second limiting groove, and the second limiting bent arm 6052 bends toward the second sub-bottom wall. In the embodiment of the present disclosure, the configuration of the second limiting arm 605 can be the same as or similar to that of the first limiting arm 604. For details, please refer to the detailed description of the first limiting arm 604, and this embodiment will not be repeated here.

[0246] In addition, in the embodiment of the present disclosure, the first limiting arm 604 and the second limiting arm 605 can be symmetrically arranged relative to the accommodating perforation 6011; in this way, the unlocking component 600 can be provided with stable limiting by the symmetrical first limiting arm 604 and the second limiting arm 605, thereby preventing the unlocking component 600 from shaking in the second recessed portion.

[0247] In some embodiments of the present disclosure, when the unlocking component 600 moves toward the first wall 2021a to the second preset position, the first limiting arm 604 abuts against the wall of the first limiting groove facing away from the second wall, and the second limiting arm 605 abuts against the wall of the second limiting groove facing away from the second wall, thereby limiting the movement range of the unlocking component 600. This prevents the unlocking component 600 from excessive movement within the second recess, which could cause fatigue of the reset element 607. This effectively increases the service life of the reset element 607, and thus increases the number of effective unlocking times of the unlocking component 600.

[0248] In some examples of the disclosed embodiments, the force-applying member 603 includes two unlocking arms 6031 extending along the second wall. The two unlocking arms 6031 are arranged side by side along the width of the lower housing, with a clearance gap 6032 provided between the two unlocking arms 6031 to allow clearance for the locking portion. When the optical module is locked with the host computer, the locking portion is positioned within the clearance gap 6032, with the two unlocking arms 6031 positioned on either side of the locking portion.

[0249] In some examples, the force member 603 has a fourth bent portion 60311, and the fourth bent portion 60311 is bent from one end of the force member 603 facing away from the body 601 toward the second wall surface, and the fourth bent portion 60311 is attached to the side of the force member 603 facing the second wall surface. In some examples, the fourth bent portion 60311 can be formed by bending a portion of the unlocking arm 6031 toward the second wall surface. In some embodiments of the present disclosure, by providing the fourth bent portion 60311, the strength of the force member 603 can be improved, ensuring that the force member 603 will not bend and deform during the unlocking process, thereby ensuring the effectiveness of the unlocking component 600 in unlocking the optical module. Specifically, when the unlocking component 600 is in the reset state, the fourth bent portion 60311 can sink into the sinking groove.

[0250] Figure 38 is a schematic diagram of another embodiment of the unlocking component of an optical module according to an embodiment of the present disclosure. Referring to Figure 38 , in this embodiment, the unlocking component 600 further includes a rubber-coated handle 606. One end of the rubber-coated handle 606 wraps around the end of the body 601 facing away from the second wall. The other end of the rubber-coated handle 606 extends outside the second recessed portion, and the rubber-coated handle 606 is positioned between the third and fourth limiting walls.

[0251] It is understood that in the disclosed embodiment, a portion of the rubber-coated handle 606 may be located between the third and fourth limiting walls. Another portion of the rubber-coated handle 606 may extend to the side of the first wall facing away from the second wall. To remove or extract the optical module from the host computer, the rubber-coated handle 606 can be pulled, causing it to move the unlocking component body 601, ejector 602, and force-applying member 603 toward the first wall.

[0252] In some embodiments of the present disclosure, since the rubber-coated handle 606 is covered on the end of the main body 601 facing away from the second wall, the size of the rubber-coated handle 606 is slightly larger than the size of the main body 601; the width dimension between the third limiting wall and the fourth limiting wall is set to be larger than the width dimension between the first limiting wall and the second limiting wall. In this way, the gap between the rubber-coated handle 606 and the third limiting wall and the fourth limiting wall can be matched, thereby reducing the friction force on the rubber-coated handle 606 and improving the smoothness of the movement of the unlocking component 600 in the second recess when unlocking.

[0253] Since the second bottom wall is recessed in the first bottom wall, the thickness of the second bottom wall is relatively thin and difficult to process during production. In order to avoid forming a larger through hole at the second bottom wall and to avoid the rubber-coated handle 606 from entering the lower shell and interfering with the lower shell, causing the unlocking component 600 to move unsmoothly, in some examples of the embodiments of the present disclosure, a fiber optic adapter mounting structure is provided in the lower shell, and the fiber optic adapter mounting structure is located on the side of the second bottom wall facing the first bottom wall, so that the side of the second bottom wall facing the first bottom wall is a closed bottom wall.

[0254] That is to say, in some embodiments of the present disclosure, part of the second bottom wall surface can be thickened by the optical fiber adapter mounting structure in the lower shell. When the second bottom wall surface is recessed in the first bottom wall surface, the part of the second bottom wall surface provided with the optical fiber adapter mounting structure forms a closed bottom wall surface. In this way, the opening area of ​​the through hole formed in the second bottom wall surface can be reduced, thereby avoiding the interference between the rubber-coated handle 606 and the lower shell, and improving the smoothness of the movement of the unlocking component 600 in the second recessed portion.

[0255] To facilitate the connection between an external optical fiber (e.g., an optical connector of an external optical fiber) and the optical port's optical adapter, in some examples of the disclosed embodiments, the rubber-coated handle 606 is a soft component. For example, the rubber-coated handle 606 can be made of silicone, soft plastic, or soft rubber. This allows the rubber-coated handle 606 to be bent when the external optical fiber's optical connector is inserted into the optical adapter, facilitating the connection between the optical adapter and the external optical fiber connector.

[0256] As an optional example, a pull ring may be provided on the end of the rubber-coated handle 606 extending to the lower shell facing away from the upper machine. The pull ring may be in the shape of a circular hole, an elliptical hole or other special-shaped hole structures, and the embodiments of the present disclosure do not limit this.

[0257] Figure 39 is a cross-sectional view of an unlocking component in an optical module according to an embodiment of the present disclosure. Figure 40 is a partial enlarged view of point B in Figure 39. Figure 41 is an exploded view of the lower housing, unlocking component, and outer cover of an optical module according to an embodiment of the present disclosure. Referring to Figures 39-41, to enhance the connection strength between the rubber-coated handle 606 and the body 601, increase the force-bearing area of ​​the rubber-coated handle 606, and change the force direction of the rubber-coated handle 606 to prevent the rubber-coated handle 606 from falling off or breaking off from the body 601, in some embodiments of the present disclosure, a plurality of notches 6013 are provided on the end of the body 601 facing away from the second wall. The notches 6013 extend along the width of the body 601 and are arranged along the length of the body 601. In some embodiments of the present disclosure, the notches 6013 may be through holes. In some examples, the notches 6013 may also be grooves. In some embodiments of the present disclosure, the notches 6013 are described as through holes. Part of the rubber-coated handle 606 is embedded in the notch 6013. Specifically, the rubber-coated handle 606, while in a molten (liquid) state, is injected into a mold containing the body 601. The liquid rubber fills the notch 6013, and the portions on both sides of the body 601 are connected through the portion within the notch 6013 to form a single piece. This increases the force-bearing area and strength of the rubber-coated handle 606 after it is connected to the body 601, effectively preventing the rubber-coated handle 606 from being pulled apart. Furthermore, the force between the rubber-coated handle 606 and the body 601 is converted from surface friction to tension within the notch 6013, increasing the force exerted by the rubber-coated handle 606 on the body 601 and preventing it from falling off the body 601.

[0258] In some embodiments of the present disclosure, the thickness of the portion of the rubber-coated handle 606 that covers the body 601 is greater than the thickness of the end of the rubber-coated handle 606 that faces away from the second wall. This not only enhances the strength of the connection between the rubber-coated handle 606 and the body 601, but also saves material for the rubber-coated handle 606, reducing processing and production costs.

[0259] Figure 42 is a schematic diagram of one structure of an inner and outer cover plate of an optical module according to an embodiment of the present disclosure, Figure 43 is a schematic diagram of another structure of an inner and outer cover plate of an optical module according to an embodiment of the present disclosure, Figure 44 is a schematic diagram of yet another structure of an inner and outer cover plate of an optical module according to an embodiment of the present disclosure, and Figure 45 is a partial enlarged view of point C in Figure 44. Referring to Figures 41-45, the outer cover plate 700 includes a first protruding portion 701, a cover plate body 702, and a first extending portion 703; wherein the first protruding portion 701 includes a first bent portion 7011 and a second bent portion 7012.

[0260] In some examples, the outer cover 700 may be made of sheet metal, wherein the cover body 702 may be covered on the first wall 2021 a and located on the side of the unlocking component facing away from the lower shell 202 .

[0261] The first extension portion 703 can extend from one end of the cover body 702 toward the second wall. For example, the first extension portion 703 can be arranged at the end of the cover body 702 facing the second wall. In some examples, the first extension portion 703 and the cover body 702 can be an integral part. For example, the sheet metal can be cut to form the first extension portion 703. Among them, the first bending portion 7011 can have the end of the first extension portion 703 facing the second wall (i.e., the end facing away from the cover body 702) bend toward the lower shell 202 (generally, it can also be understood as bending toward the inner side of the cover body 702); in some embodiments of the present disclosure, the first bending portion 7011 is attached to the inner wall surface of the first extension portion 703. In this way, the space occupied by the first bending portion 7011 can be reduced, which facilitates the arrangement of the second bending portion 7012.

[0262] In some embodiments of the present disclosure, the second bending portion 7012 is bent from the first bending portion 7011 toward the lower shell 202 , and the second bending portion 7012 can serve as the first protruding portion 701 .

[0263] That is, in some embodiments of the present disclosure, the first protrusion 701 and the outer cover 700 can be an integral structure, that is, the first protrusion 701 is formed by cutting and bending a sheet metal. In this way, because the first protrusion 701 is formed by bending the sheet metal, the first protrusion 701 has a certain degree of elasticity, which can improve the smoothness of the reset of the unlocking component.

[0264] In the embodiment of the present disclosure, the cover plate body 702, the first extension portion 703, the first bent portion 7011 and the second bent portion 7012 are formed by cutting and bending the sheet metal, which are used to support the unlocking component when it is reset; in this way, the processing and forming of the first protrusion 701 is facilitated, and the processing and production cost of the first protrusion 701 is effectively saved.

[0265] In some examples of the embodiments of the present disclosure, the second bent portion 7012 includes a first sub-bend segment 70121 and a second sub-bend segment 70122. The first sub-bend segment 70121 is bent from the first bent portion 7011 toward the lower housing 202. That is, in the embodiments of the present disclosure, after the first bent portion 7011 is bent and affixed to the inner wall of the first extension portion 703, the end of the first bent portion 7011 continues to bend toward the lower housing 202, thereby forming the first sub-bend segment 70121. In the embodiment of the present disclosure, the second sub-bending section 70122 is bent from the first sub-bending section 70121 toward the lower shell 202; that is, the end of the first sub-bending section 70121 is toward the lower shell, and the head end of the second sub-bending section 70122 is also toward the lower shell, and the end of the second sub-bending section is toward the inner wall surface of the outer cover plate 700; in this way, an arc-shaped bending portion 70123 is formed at the connection between the first sub-bending section 70121 and the second sub-bending section 70122, and when the unlocking component moves toward the second wall surface 2022a, the arc-shaped bending portion 70123 abuts against the pushing member.

[0266] In some embodiments of the present disclosure, the second bending portion 7012 is set as two sub-bending sections, wherein the first sub-bending section 70121 is bent toward the lower shell body, and the second sub-bending section 70122 is bent away from the lower shell body; in this way, an arc-shaped bending portion 70123 is formed at the connection between the first sub-bending section 70121 and the second sub-bending section 70122; the pushing member is pushed against by the arc-shaped bending portion 70123, so that the contact part between the first protrusion 701 and the pushing member is smoother, which can effectively prevent the pushing member from being scratched, thereby improving the smoothness of the reset of the unlocking member and avoiding the jamming of the unlocking member.

[0267] In some examples of the presently disclosed embodiments, the width of the first extension 703 is smaller than the width of the cover body 702, and the width of the second bent portion 7012 is smaller than the width of the first bent portion 7011. In other words, in some examples of the presently disclosed embodiments, when forming the first extension 703 at the end of the cover body 702 facing the second wall, the first extension 703 can be formed by cutting the sheet metal, thereby making the width of the first extension 703 smaller than the width of the cover body 702. This facilitates bending the first extension 703 to form the first bent portion 7011 and reduces stress during bending of the first extension 703. In addition, when the first bending portion 7011 is bent to form the second bending portion 7012, the side of the first bending portion 7011 can be cut again so that the width of the second bending portion 7012 is smaller than the width of the first bending portion 7011; in this way, when the second bending portion 7012 is bent to form the second bending portion 7012, the stress when bending the second bending portion 7012 can be reduced.

[0268] Furthermore, when the outer cover 700 is mounted on the first wall, the cover body 702 is embedded in the first sub-recess, with the outer wall of the cover body 702 flush with the first wall. The first extension 703 is embedded in the second sub-recess, with the outer wall of the first extension 703 flush with the first wall. The second bent portion 7012 can be embedded in the second recess. The sidewall of the first extension 703 can contact the sidewall of the second sub-recess, allowing the second sub-recess to limit the position of the first extension 703.

[0269] As an optional example, the width of the second bent portion 7012 can be slightly smaller than the width of the second recessed portion. In this way, when the outer cover 700 is installed on the first wall, the second bent portion 7012 is embedded in the second recessed portion and fits in the gap with the side wall of the second recessed portion, which facilitates the installation of the outer cover 700 and improves the installation efficiency of the outer cover 700.

[0270] In some embodiments of the present disclosure, a first recess is provided on the first wall surface, and the first recess is provided to include a first sub-recess and a second sub-recess; in this way, the cover body 702 can be embedded in the first sub-recess, and the first extension portion 703 can be embedded in the second sub-recess, so that the surface of the outer cover 700 can be flush with the first wall surface, thereby maintaining the overall flatness of the outer surface of the optical module. In some embodiments of the present disclosure, the second bending portion 7012 has a first side wall surface 70124 and a second side wall surface 70125 opposite to each other along the width direction; as shown in Figure 20, the first bending portion 7011 has a third side wall surface 70111 and a fourth side wall surface 70112; there is a first notch 70113 between the third side wall surface 70111 and the first side wall surface 70124, and a second notch 70114 between the fourth side wall surface 70112 and the second side wall surface 70125. The first notch 70113 and the second notch 70114 are used to release the bending stress between the second bending portion 7012 and the first bending portion 7011.

[0271] In some examples, after cutting the two side edges of the first bend portion 7011, the first side wall surface 701244 of the second bend portion 7012 can continue to be cut toward the first bend portion 7011 to form a first notch 70113, wherein the processing and forming method of the second notch 70114 can be the same or similar to that of the first notch 70113, and the embodiments of the present disclosure will not be repeated here.

[0272] In the embodiment of the present disclosure, the width of the first extension portion 703 is set to be smaller than the width of the cover body 702, the width of the second bending portion 7012 is set to be smaller than the first bending portion 7011, and a first notch 70113 is set between the first side wall surface 70124 of the second bending portion 7012 and the third side wall surface 70111 of the first bending portion 7011, and a second notch 70114 is set between the second side wall surface 70125 and the fourth side wall surface 70112; in this way, when bending to form the second bending portion 7012, the first notch 70113 and the second notch 70114 can release the stress generated by the bending of the second bending portion 7012, facilitate the bending and forming of the second bending portion 7012, and can effectively protect the first bending portion 7011 from being torn by the stress generated by the bending of the second bending portion 7012; that is, it facilitates the processing and forming of the first bending portion 7011 and the second bending portion 7012, thereby ensuring the structural integrity of the outer cover 700.

[0273] In some examples of the disclosed embodiments, the outer cover 700 further includes a second extension 704 and a third bend 705. The second extension 704 is located at the end of the cover body 702 facing away from the second wall, extending away from the second wall. The width of the second extension 704 is smaller than that of the cover body 702, and the second extension 704 is limited between the third limiting wall and the fourth limiting wall. The third bend 705 bends from the end of the second extension 704 facing away from the second wall toward the lower shell, and the third bend 705 is in contact with the inner wall of the second extension 704. The width of the third bend 705 is greater than that of the second extension 704, so that the end of the third bend 705 contacts the inner wall of the cover body 702. It should be noted that the width of the third bend 705 and the width of the second extension 704 may refer to the dimensions along the length direction of the lower shell. In some embodiments of the present disclosure, the width of the third bending portion 705 is set to be greater than the width of the second extending portion 704. This facilitates bending and forming the third bending portion 705, improves the convenience of processing and production, and improves the yield rate of optical module products.

[0274] In some examples, the length dimension of the second extension portion 704 can be slightly smaller than the width between the third limiting wall and the fourth limiting wall; in this way, the second extension portion 704 can be easily embedded between the third limiting wall and the fourth limiting wall, and limit the installation of the outer cover 700, for example, limiting the outer cover 700 along the width direction of the lower shell.

[0275] In addition, in some embodiments of the present disclosure, the second extension portion 704 can be covered on the side of the rubber-coated handle facing away from the lower shell, thereby limiting the rubber-coated handle. That is to say, in the embodiments of the present disclosure, the second extension portion 704 can also play a certain limiting role on the rubber-coated handle in the direction facing away from the lower shell.

[0276] In addition, in some embodiments of the present disclosure, a third bending portion 705 is formed by bending the end of the second extension portion 704. In this way, a bent arc is formed at the end of the second extension portion 704 facing away from the second wall surface, which can avoid the formation of burrs or burrs at the end of the second extension portion 704. The end of the second extension portion 704 is an arc shape, which can avoid scratches on other components. In addition, when assembling an external optical fiber connector, the rubber-coated handle is bent toward the second extension portion 704, which can also avoid scratches on the rubber-coated handle, thereby effectively extending the service life of the rubber-coated handle.

[0277] In other examples of the embodiments of the present disclosure, the outer wall surface of the cover body 702 is recessed to form a recessed groove 7021, and the recessed groove 7021 is used to accommodate the label, and the depth of the recessed groove 7021 is greater than the thickness of the label. In the embodiments of the present disclosure, the recessed groove 7021 can be obtained by stamping the cover body 702. In some examples, the recessed groove 7021 can also be obtained by cold rolling, and the embodiments of the present disclosure are not limited to this. In some embodiments of the present disclosure, the label can be affixed to the recessed groove 7021, and the thickness of the label is usually 0.2mm; in some embodiments of the present disclosure, the depth of the recessed groove 7021 can be 0.4mm-0.5mm. In this way, the label sinks into the recessed groove 7021, and during the transportation, transshipment, transfer or use of the optical module, the label can be prevented from being hung up, thereby protecting the label.

[0278] In some examples of the embodiments of the present disclosure, a second protrusion 7022 is formed on the inner wall surface of the cover body 702 corresponding to the recessed groove 7021. The protrusion height of the second protrusion 7022 is greater than the thickness of the third bent portion 705. It will be understood that in some embodiments of the present disclosure, when the recessed groove 7021 is stamped into the cover body 702, the second protrusion 7022 is formed on the opposite side of the recessed groove 7021; thus, the second protrusion 7022 can enhance the strength of the cover body 702. When the unlocking component moves toward the first wall, due to the setting of the pushing member, the unlocking component simultaneously moves back to the lower shell body (i.e. facing the outer cover plate 700). When the unlocking component moves to the unlocking position, the unlocking component abuts against the inner wall of the outer cover plate 700. In the embodiment of the present disclosure, a second protrusion 7022 is formed on the inner wall of the outer cover plate 700. In this way, the second protrusion 7022 abuts against the unlocking component, thereby preventing the unlocking component from pushing the outer cover plate 700 against deformation.

[0279] In some examples, the outer cover plate 700 also includes a third side plate 706 and a fourth side plate 707, the inner surface of the third side plate 706 protrudes to form a plurality of first clips 7061 arranged side by side, and the inner surface of the fourth side plate 707 protrudes to form a plurality of second clips 7071 arranged side by side; the third side plate 706 is embedded in the third recessed portion, and the first clip 7061 is locked in the first slot; the fourth side plate 707 is embedded in the fourth recessed portion, and the second clip 7071 is locked in the second slot.

[0280] In some embodiments of the present disclosure, the first card slot can be formed by punching the side wall of the third recessed portion inwardly. The first card slot can be provided with two, three, or four first card slots, etc. In the embodiments of the present disclosure, there is no limit on the number of first card slots. Among them, the setting method of the second card slot can be the same as or similar to that of the first card slot, which will not be described in detail in the embodiments of the present disclosure. In some examples, the second card slot can be symmetrically arranged with the first card slot. In this way, the positioning process when setting the first card slot and the second card slot can be reduced, thereby improving processing efficiency.

[0281] Correspondingly, the first clip 7061 can also be stamped out of the third side panel 706, and the number of the first clips 7061 can be the same as the number of the first slots; in addition, the setting method of the second clip 7071 can also be the same or similar to that of the first clip 7061, which will not be repeated in the embodiment of the present disclosure.

[0282] In some embodiments of the present disclosure, when assembling the outer cover plate 700, the third side plate 706 can be inserted into the third recessed portion, the fourth side plate 707 can be inserted into the fourth recessed portion, and the first clip 7061 can be inserted into the first slot, and the second clip 7071 can be inserted into the second slot, thereby improving the installation and assembly efficiency of the outer cover plate 700.

[0283] In some examples, the wall of the third side plate 706 contacts the wall of the third recess, and the wall of the fourth side plate 707 contacts the wall of the fourth recess, thereby limiting the outer cover plate 700 and improving the stability of the installation of the outer cover plate 700.

[0284] In other examples, the thickness of the third side panel 706 is the same as or similar to the depth of the third recess, so that when the third side panel 706 is inserted into the third recess, the outer wall surface of the third side panel 706 is flush with the outer wall surface of the first side panel; accordingly, the thickness of the fourth side panel 707 is the same as or similar to the depth of the fourth recess, so that when the fourth side panel 707 is inserted into the fourth recess, the outer wall surface of the fourth side panel 707 is flush with the outer wall surface of the second side panel, thereby improving the flatness of the surface of the optical module.

[0285] Figure 46 is a cross-sectional view of the unlocking component and the lower housing of the optical module according to an embodiment of the present disclosure, Figure 47 is a partial enlarged view of point D in Figure 46, Figure 48 is a partial enlarged view of the unlocking component of the optical module according to an embodiment of the present disclosure when it is moved to a preset position, Figure 49 is another cross-sectional view of the unlocking component and the lower housing of the optical module according to an embodiment of the present disclosure, and Figure 50 is a partial enlarged view of point E in Figure 49. Referring to Figures 46-50, in some examples of the present disclosure, when it is necessary to unplug or extract the optical module from the host computer, the unlocking component can be moved toward the first wall 2021a. For example, as shown in Figure 46, the unlocking component 600 can be moved along the negative x-axis in Figure 46. At this time, the ejector 602 moves from the second wall 2022a to the first wall 2021a. That is, when the optical module is inserted into the host computer and the optical module and the host computer are in a locked state, the ejection member 602 can be located on the second wall surface 2022a, or partially located on the second wall surface 2022a; when the unlocking component 600 moves toward the first wall surface 2021a, the ejection member 602 moves from the second wall surface 2022a to the first wall surface 2021a. In some examples, the ejection member 602 can move completely to the first wall surface 2021a, or partially move to the first wall surface 2021a.

[0286] In some embodiments of the present disclosure, the first wall 2021a protrudes from the second wall 2022a. When the ejection member 602 moves from the second wall 2022a toward the first wall 2021a, a step formed between the first wall 2021a and the second wall 2022a (e.g., the ejection wall 2152 described in detail in the previous embodiments of the present disclosure) abuts against the surface of the ejection member 602 facing the lower housing 202. As a result, the ejection member 602 is subjected to a force applied by the ejection member 602, thereby raising the height of the ejection member 602. At this time, the entire unlocking component 6 moves away from the lower housing 202 under the drive of the ejection member 602. For example, as shown in FIG. 46 , the entire unlocking component 600 moves in the direction indicated by the positive direction of the y-axis in FIG. 46 , for example, from the state shown in FIG. 46 to the state shown in FIG. 50 .

[0287] In some embodiments of the present disclosure, the force member 603 is connected to one end of the push member 602 facing the locking portion. In some embodiments of the present disclosure, the force member 603 can be parallel or approximately parallel to the second wall 2022a. It can be understood that when the unlocking component moves toward the first wall 2021a, due to the interaction between the push member 602 and the push wall 2152 between the first wall 2021a and the second wall 2022a, the entire unlocking component moves back toward the lower shell 202 under the drive of the push member 602; at this time, the force member 603 moves back toward the second wall 2022a, thereby pushing the locking spring on the upper computer cage away from the locking portion 20221, thereby unlocking the optical module and the upper computer.

[0288] In some optional examples of the embodiments of the present disclosure, due to the setting of the push-up member 602, when the unlocking member 600 moves toward the first wall 2021a, the unlocking member 600 is pushed by the push-up member 602 as a whole and moves back toward the lower shell body; to ensure that when the optical module is inserted into the upper computer, the force-applying member 603 is located between the locking spring of the upper computer and the second wall 2022a, in some embodiments of the present disclosure, a first protrusion 701 is provided on the side of the outer cover 700 facing the push-up member 602; when the unlocking member 600 moves toward the second wall surface to the first preset position (for example, along the position shown in Figure 48), the first protrusion 701 contacts the push-up member 602 to cause the unlocking member 600 to move toward the lower shell body, and when the unlocking member 600 is in the reset state, the first protrusion 701 is interference fit with the unlocking member 600.

[0289] That is to say, in some embodiments of the present disclosure, after the unlocking component 600 unlocks the optical module and the host computer, the unlocking component 600 first moves along the length direction of the first wall 2021a or the second wall 2022a during the process of moving and resetting toward the second wall 2022a; when the unlocking component 600 moves to the first preset position, the pushing member 602 contacts the first protrusion 701. Since the pushing member 602 is inclined, the force of the first protrusion 701 on the pushing member 602 can be decomposed into a force vertically pointing to the lower shell 202 and a force along the length direction of the lower shell 202; at this time, the unlocking component 600 continues to move along the length direction of the lower shell 202 under the action of the resetting force, and the force of the first protrusion 701 on the pushing member 602 pushes the entire unlocking component 600 to move toward the lower shell 202, so that the force-applying member 603 is attached to the second wall 2022a.

[0290] In some examples, the first protrusion 701 can be a ridge, rib, or spring element provided on the inner wall of the outer cover 700. The first protrusion 701 can extend along the width of the outer cover 700; wherein, the length of the first protrusion 701 can match the width of the unlocking component. For example, the length of the first protrusion 701 can be the same as, close to, or similar to the width of the unlocking component.

[0291] In some possible examples, when the unlocking member is in the reset state, the first protrusion 701 can abut against the top end of the ejection member that is connected to the body 601. In this way, when the unlocking member is in the reset state, the first protrusion 701 and the unlocking member can be in an interference fit state, so that the force applying member 603 is completely in contact with the second wall surface.

[0292] The optical module provided by the embodiment of the present disclosure forms a housing cavity by covering the upper shell and the lower shell, and arranges the circuit board and the optical transceiver component in the housing cavity, which facilitates the arrangement of the circuit board and the optical transceiver component and improves the installation and assembly efficiency of the optical module; a first wall surface and a second wall surface are provided on the lower shell surface, the second wall surface is recessed in the first wall surface, and a locking portion is provided on the second wall surface; in this way, when the optical module is inserted into the upper computer, the locking portion on the second wall surface establishes a locking relationship with the outside, for example, locking with the locking structure on the cage of the upper computer; the embodiment of the present disclosure In the embodiment, the body of the unlocking component is arranged on the first wall surface, the pushing member of the unlocking component is arranged obliquely relative to the body, and the force-applying member is arranged at one end of the pushing member facing the locking portion; in this way, when the optical module needs to be pulled out from the upper computer, the unlocking component can be moved toward the first wall surface, and the pushing member moves from the second wall surface to the first wall surface, and pushes the unlocking component as a whole to move back toward the lower shell body, so that the force-applying member pushes the locking structure on the cage of the upper computer away from the locking portion, thereby unlocking the locking portion; in addition, an outer cover plate is arranged on the first wall surface, and the outer cover plate is arranged on the The unlocking component faces away from the side of the lower shell body, so that the outer cover plate limits the unlocking component on the lower shell body and moves along the length direction of the lower shell body, and a movable gap of the unlocking component is left between the outer cover plate and the lower shell body, so that when the unlocking component moves toward the first wall surface, the pushing member moves from the second wall surface to the first wall surface, thereby pushing the entire unlocking component in the direction away from the lower shell body, so that it is convenient for the force-applying member to apply a force to the locking structure of the upper machine cage; in the embodiment of the present disclosure, a first protrusion is provided on the side of the outer cover plate facing the pushing member, and the first protrusion can selectively abut against the pushing member during the process of the unlocking component moving and resetting toward the second wall surface, so that the first protrusion has a force on the pushing member facing the lower shell body, so that the unlocking component moves toward the lower shell body while returning to the second wall surface, so that the force-applying member can be attached to the second wall surface and move during the process of returning the unlocking component from the first preset position, so that the force-applying member is inserted into the lower side of the locking structure of the upper machine cage, so that the unlocking component is normally reset and smoothly unlocked at the next unlocking, thereby improving the smoothness and stability of the unlocking component.

[0293] In some examples of the embodiments of the present disclosure, when the unlocking component moves toward the first wall surface to a first preset position (for example, as shown in FIG. 22 , the first preset position may be the position where the ejecting component 602 begins to contact the ejecting wall surface 2152), the ejecting component 602 separates from the first protrusion 701. When the unlocking component continues to move toward the first wall surface, a certain gap is formed between the ejecting component 602 and the first protrusion 701. In other words, in some embodiments of the present disclosure, when the unlocking component moves toward the first wall surface to the first preset position, the force between the first protrusion 701 and the ejecting component 602 is zero. After the unlocking component continues to move a certain distance and reaches the unlocked position, the force-applying member 603 completely unlocks the optical module from the host computer.

[0294] When the unlocking component moves toward the second wall to the first preset position, the first protrusion 701 contacts the push-up member 602, so that the unlocking component 600 moves toward the lower shell body, and when the unlocking component is in the reset state, the vertical distance between the first protrusion 701 and the second wall is smaller than the vertical distance between the surface of the main body 601 facing away from the second wall and the second wall.

[0295] That is to say, when the unlocking component 600 is in the reset state, at least one of the first protrusion 701 and the unlocking component may undergo a certain deformation; for example, the first protrusion 701 may have a certain deformation facing away from the lower shell body; in some examples, since the unlocking component is supported by sheet metal, the unlocking component may also have a certain deformation; or, in other examples, both the first protrusion 701 and the unlocking component may undergo a certain deformation.

[0296] In the embodiment of the present disclosure, the pushing member 602 is configured to separate from the first protrusion 701 when the unlocking member moves toward the first wall to the first preset position, and when the unlocking member moves toward the second wall to the first preset position, the first protrusion 701 contacts the pushing member 602, thereby causing the unlocking member to move toward the lower shell body, and when the unlocking member is in a reset state, the vertical distance between the first protrusion 701 and the second wall surface is smaller than the vertical distance between the surface of the main body 601 facing away from the second wall surface and the second wall surface; in this way, when the optical module and the upper computer are in a locked state or the unlocking member is in a reset state, the unlocking member 600 can be subjected to the pressing force directed to the lower shell body provided by the first protrusion 701, so that the unlocking member and the lower shell body are fitted together, which facilitates the stable locking of the optical module and the upper computer.

[0299] 51 , the first lower side plate 2022b may be provided with a first recessed area 210. The first recessed area 210 is recessed toward the inner cavity of the wrapping cavity, so that the first recessed area 210 is recessed in the first lower side plate 2022b.

[0300] The first lower side plate 2022b may be provided with a first locking slot 2028b that is recessed inwardly in the first lower side plate 2022b and communicates with the first recessed area 210 .

[0301] In some embodiments, the unlocking component 600 may include an unlocker 620b installed on the outer side of the lower housing 202, with one end of the unlocker 620b embedded in the first recessed area 210 and the first locking slot 2028b on the first lower side plate 2022b.

[0302] After one end of the unlocker 620b is inserted into the first recessed area 210 and the first locking slot 2028b, one end of the unlocker 620b is recessed into the first lower side plate 2022b, so that the locking piece of the cage 106 can be easily inserted into the recessed area of ​​the unlocker 620b, thereby fixing the optical module 200 and the cage 106 through the locking piece.

[0303] 52 and 53 , the unlocking component 600 may include a handle 610 b (in some examples, the grip portion may include the handle 610 b ). The handle 610 b is connected to the unlocking mechanism 620 b . An operator may grasp the handle 610 b to push the unlocking component 600 inward, thereby inserting the optical module 200 into the cage 106 and locking the optical module 200 with the cage 106 .

[0304] Alternatively, the operator may grasp the handle 610 b to pull the unlocking component 600 outward, thereby pulling the optical module 200 out of the cage 106 , thereby unlocking the optical module 200 from the cage 106 .

[0305] In some embodiments, the handle 610b may be formed with a gripping hole 611b (also referred to as a through hole 611 in some examples). The gripping hole 611b runs through the handle 610b, and an operator can push the unlocker 620b inward by gripping the gripping hole 611b, or pull the unlocker 620b outward by gripping the gripping hole 611b.

[0306] To achieve the installation of the unlocker 620b and the lower housing 202, the unlocker 620b may include a first unlocking arm 621b. The first unlocking arm 621b is connected to the handle 610b and is installed on the first lower side plate 2022b.

[0307] The unlocker 620b may include a second unlocking arm 622. The second unlocking arm 622 is connected to the handle 610b and is mounted on the second lower side plate 2023b of the lower housing 202, so that the first unlocking arm 621b and the second unlocking arm 622 are symmetrically arranged, thereby mounting the first unlocking arm 621b and the second unlocking arm 622 on the outer side of the lower housing 202.

[0308] The unlocker 620 b may include a connecting arm 623 . One end of the connecting arm 623 is connected to the first unlocking arm 621 b , and the other end of the connecting arm 623 is connected to the second unlocking arm 622 .

[0309] In some embodiments, the first unlocking arm 621 b and the second unlocking arm 622 are connected by a connecting arm 623 , so that the first unlocking arm 621 b , the second unlocking arm 622 and the connecting arm 623 form a U-shaped unlocker.

[0310] In some embodiments, the connecting arm 623 is connected to the outer side of the lower base plate 2021 b to place the lower housing 202 in the U-shaped unlocker, so that the unlocker 620 b is located outside the lower housing 202 .

[0311] 53 , the unlocker 620b may include a first connecting portion 624. The first connecting portion 624 is located at one end of the first unlocking arm 621b, and the first connecting portion 624 is inserted into the handle 610b to achieve connection between the first unlocking arm 621b and the handle 610b.

[0312] The unlocker 620b may include a second connecting portion 625. The second connecting portion 625 is located at one end of the second unlocking arm 622, and the second connecting portion 625 is inserted into the handle 610b to achieve connection between the second unlocking arm 622 and the handle 610b.

[0313] In some embodiments, the first connection portion 624 and the second connection portion 625 may be symmetrically arranged, and the first connection portion 624 may be a planar connection portion having a mounting hole formed thereon, through which the first connection portion 624 and the handle 610b may be connected by screws through the mounting hole.

[0314] In some embodiments, the first connection portion 624 and the second connection portion 625 can be symmetrically arranged, and the first connection portion 624 can be an L-shaped connection portion, which can increase the connection area between the first unlocking arm 621b and the handle 610b to improve the connection stability between the first unlocking arm 621b and the handle 610b.

[0315] The first unlocking arm 621b and the second unlocking arm 622 have the same structure, so the first unlocking arm 621b and the second unlocking arm 622 are symmetrically arranged on both sides of the lower shell 202, so that when force is applied to the unlocker 620b, the force can be evenly distributed on the first unlocking arm 621b and the second unlocking arm 622.

[0316] In some embodiments, the first unlocking arm 621b may include a first support arm 6210. One end of the first support arm 6210 is connected to the first connecting portion 624, and the first support arm 6210 is installed on the outer side of the first lower side plate 2022b.

[0317] The first unlocking arm 621b may include a first inclined surface 6211. One end (the left end as shown in FIG. 7 ) of the first inclined surface 6211 is fixedly connected to the first supporting arm 6210.

[0318] The first unlocking arm 621b may include a second inclined surface 6212. One end (the left end as shown in FIG. 7 ) of the second inclined surface 6212 is fixedly connected to one end (the right end as shown in FIG. 53 ) of the first inclined surface 6211.

[0319] The first unlocking arm 621b may include a first locking hook 6213. The first locking hook 6213 is located at an end of the second inclined surface 6212 away from the first inclined surface 6211 (the right end as shown in FIG. 53).

[0320] In some embodiments, the first inclined surface 6211 is tilted toward the inner cavity of the wrapped cavity, so that the first inclined surface 6211 is tilted from the outside to the inside.

[0321] The second inclined surface 6212 is inclined toward the first lower side plate 2022 b , so that the second inclined surface 6212 is inclined from inside to outside.

[0322] In some embodiments, when the first inclined surface 6211 is inclined from outside to inside and the second inclined surface 6212 is inclined from inside to outside, the first inclined surface 6211 and the second inclined surface 6212 form a first groove, which is a V-shaped groove.

[0323] In some embodiments, the first inclined surface 6211 may also be a curved surface, and the second inclined surface 6212 may also be a curved surface. The first inclined surface 6211 and the second inclined surface 6212 may form a U-shaped groove.

[0324] In some embodiments, the central axis of the first locking hook 6213 coincides with the central axis of the second inclined surface 6212, so that there is a first distance between the top surface of the first locking hook 6213 and the top surface of the second inclined surface 6212, and there is a second distance between the bottom surface of the first locking hook 6213 and the bottom surface of the second inclined surface 6212, and the first distance is the same as the second distance.

[0325] When the first unlocking arm 621b is installed on the first lower side plate 2022b, the first inclined surface 6211 and the second inclined surface 6212 are located in the first recessed area 210 of the first lower side plate 2022b, and the first locking hook 6213 is embedded in the first locking slot 2028b of the first lower side plate 2022b to realize the connection between the first unlocking arm 621b and the first lower side plate 2022b.

[0326] In some embodiments, referring to Figure 51 , the first recessed area 210 may include a first side surface 2024b. One side of the first side surface 2024b is connected to the first lower side plate 2022b, and the first side surface 2024b is tilted toward the inner cavity of the enclosing cavity, such that the first side surface 2024b is tilted from the outside to the inside.

[0327] The first recessed area 210 may include a second side surface 2025b connected to the other side of the first side surface 2024b. The second side surface 2025b is tilted toward the first lower plate 2022b so as to tilt from inside to outside.

[0328] The first recessed area 210 may include a third side surface 2026b connected to the other side of the second side surface 2025b. The third side surface 2026b is tilted toward the inner cavity of the cavity so as to tilt from outside to inside.

[0329] The first recessed area 210 may include a fourth side surface 2027b connected to the other side of the third side surface 2026b, and disposed along the length of the first lower plate 2022b such that the fourth side surface 2027b is parallel to the outer side surface of the first lower plate 2022b and recessed in the outer side surface of the first lower plate 2022b.

[0330] In some embodiments, the first side 2024b is tilted from outside to inside, the second side 2025b is tilted from inside to outside, the third side 2026b is tilted from outside to inside, and the fourth side 2027b is set in parallel. In this way, the first side 2024b, the second side 2025b, the third side 2026b and the fourth side 2027b form a first recessed area 210 that is recessed inward.

[0331] The first recessed area 210 may include a first supporting surface 2030. The second side surface 2025b is recessed into the outer side surface of the first lower side plate 2022b at one end thereof facing the first lower side plate 2022b, such that the first supporting surface 2030 is exposed on the first lower side plate 2022b, and the outer edge of the first supporting surface 2030 is flush with the outer side surface of the first lower side plate 2022b.

[0332] In some embodiments, the first bearing surface 2030 is recessed in the mounting surface of the first locking slot 2028b, that is, the mounting surface of the first locking slot 2028b is located above the first bearing surface 2030, and the first bearing surface 2030 and the mounting surface of the first locking slot 2028b form a step surface.

[0333] In some embodiments, the first lower side plate 2022b may be provided with a first connecting surface 2020 . The first connecting surface 2020 is perpendicular to the lower base plate 2021b , one end of the first connecting surface 2020 is connected to the mounting surface of the first locking slot 2028b , and the other end of the first connecting surface 2020 is connected to the first bearing surface 2030 .

[0334] In some embodiments, there is a gap between the connection between the third side surface 2026 b and the fourth side surface 2027 b and the first connecting surface 2020 , so as to limit the first unlocking arm 621 b through the first connecting surface 2020 .

[0335] In some embodiments, when the first unlocking arm 621b is installed on the first lower side plate 2022b, the bottom surface of the first unlocking arm 621b is installed on the first supporting surface 2030 to support the first unlocking arm 621b through the first supporting surface 2030.

[0336] The first inclined surface 6211 is embedded in the recessed area between the first side surface 2024b, the second side surface 2025b and the third side surface 2026b, and the second inclined surface 6212 is embedded in the gap between the third side surface 2026b and the first connecting surface 2020, so that the right end of the second inclined surface 6212 is against the first connecting surface 2020, and the second inclined surface 6212 is limited in the left and right directions by the first connecting surface 2020.

[0337] 53 , the second unlocking arm 622 may include a second support arm 6220. One end of the second support arm 6220 is connected to the second connecting portion 625, and the second support arm 6220 is installed on the outer side of the second lower side plate 2023b.

[0338] The second unlocking arm 622 may include a third inclined surface 6221. One end (the left end as shown in FIG. 53) of the third inclined surface 6221 is fixedly connected to the second supporting arm 6220.

[0339] The second unlocking arm 622 may include a fourth inclined surface 6222. One end (the left end as shown in FIG. 53) of the fourth inclined surface 6222 is fixedly connected to one end (the right end as shown in FIG. 53) of the third inclined surface 6221.

[0340] The second unlocking arm 622 may include a second locking hook 6223. The second locking hook 6223 is located at an end of the fourth inclined surface 6222 away from the third inclined surface 6221 (the right end as shown in FIG. 53).

[0341] In some embodiments, the third inclined surface 6221 is tilted toward the inner cavity of the wrapped cavity, so that the third inclined surface 6221 is tilted from the outside to the inside.

[0342] The fourth inclined surface 6222 is inclined toward the second lower side plate 2023 b , so that the fourth inclined surface 6222 is inclined from inside to outside.

[0343] In some embodiments, when the third inclined surface 6221 is inclined from outside to inside and the fourth inclined surface 6222 is inclined from inside to outside, the third inclined surface 6221 and the fourth inclined surface 6222 form a second groove, which is a V-shaped groove.

[0344] In some embodiments, the third inclined surface 6221 may also be a curved surface, and the fourth inclined surface 6222 may also be a curved surface. The third inclined surface 6221 and the fourth inclined surface 6222 may form a U-shaped groove.

[0345] When the second unlocking arm 622 is installed on the second lower side plate 2023b, the second unlocking arm 622 is installed on the supporting surface on the second lower side plate 2023b, the third inclined surface 6221 and the fourth inclined surface 6222 are located in the third recessed area of ​​the second lower side plate 2023b, and the second locking hook 6223 is embedded in the second locking slot of the second lower side plate 2023b to realize the connection between the second unlocking arm 622 and the second lower side plate 2023b.

[0346] Figure 54 is an exploded view of the assembly of the lower housing and unlocking component of an optical module according to some embodiments of the present disclosure. As shown in Figure 54, the first unlocking arm 621b is mounted on the outside of the first lower side plate 2022b, the second unlocking arm 622 is mounted on the outside of the second lower side plate 2023b, the first inclined surface 6211 and the second inclined surface 6212 are embedded in the first recessed area 210, and the third inclined surface 6221 and the fourth inclined surface 6222 are embedded in the third recessed area, so that the first groove formed by the first inclined surface 6211 and the second inclined surface 6212 is recessed in the first lower side plate 2022b, and the second groove formed by the third inclined surface 6221 and the fourth inclined surface 6222 is recessed in the second lower side plate 2023b.

[0347] After the assembly of the optical module 200 is completed, when the optical module 200 is inserted into the cage 106 of the host computer 100, the locking piece on the cage 106 is embedded in the first groove and the second groove on the unlocker 620b, so that the first groove and the second groove on the unlocker 620b are against the locking piece, thereby achieving the locking of the optical module 200 and the host computer 100, and preventing the optical module 200 from being abnormally detached.

[0348] In some embodiments, when the unlocker 620b is installed on the outer side of the side panel of the lower shell 202, the unlocker 620b can be fixedly connected to the side panel. When unlocking the optical module 200 and the host computer 100, the operator grasps the handle 610b and applies force outward, and the unlocker 620b moves outward under the force. At this time, the inclined surface on the unlocker 620b that tilts from the inside to the outside can lift the locking plate on the cage 106, so that the unlocker 620b is separated from the locking plate.

[0349] Since the right end of the unlocker 620b is embedded in the recessed area and the locking slot of the lower side panel, the unlocker 620b is fixedly connected to the lower shell 202. When the operator applies outward force, the unlocker 620b drives the lower shell 202 to move outward to pull the optical module 200 out of the upper computer 100, thereby unlocking the optical module 200 and the upper computer 100.

[0350] In some embodiments, when the unlocker 620b is installed on the outer side of the side panel of the lower housing 202, the unlocker 620b can be non-fixedly connected to the side panel, and the unlocker 620b can move back and forth within a certain range on the side panel. When the unlocker 620b moves back and forth, the locking plate is lifted, and then the lower housing 202 is driven to move, thereby pulling the optical module 200 out of the cage 106.

[0351] 51 , in some embodiments, to allow the unlocker 620b to move forward and backward within a certain range on the lower housing 202, a first limiting slot 2029 may be formed on the first bearing surface 2030. The first limiting slot 2029 is recessed in the first bearing surface 2030 and has an opening formed on a side of the first limiting slot 2029 facing away from the lower base plate 2021b.

[0352] The first limiting slot 2029 is arranged along the length direction of the lower shell 202, and the first limiting slot 2029 extends from the first connecting surface 2020 to the outside of the second side surface 2025b. The limiting length of the first limiting slot 2029 is the unlocking stroke size of the unlocker 620b. The first limiting slot 2029 is used to limit the movement of the first unlocking arm 621b.

[0353] 53 , a first protrusion 6217 may be provided on the second inclined surface 6212 . The first protrusion 6217 is located in a direction from the second inclined surface 6212 toward the lower bottom plate 2021 b , and the first protrusion 6217 protrudes from the bottom surface of the second inclined surface 6212 .

[0354] When the first unlocking arm 621b is placed outside the first lower side plate 2022b, the first protrusion 6217 is embedded in the first limiting slot 2029. When the optical module 200 is unlocked, the unlocking member 620b is forced to move leftward, and the first protrusion 6217 moves leftward along the first limiting slot 2029, while the lower housing 202 does not move.

[0355] Similarly, a third limiting slot can be formed on the bearing surface of the second lower side plate 2023b. The third limiting slot is recessed in the bearing surface of the second lower side plate 2023b and is used to limit the movement of the second unlocking arm 622.

[0356] 53 , a third protrusion 6227 may be provided on the fourth inclined surface 6222 . The third protrusion 6227 is located in a direction from the fourth inclined surface 6222 toward the lower bottom plate 2021 b and protrudes from the bottom surface of the fourth inclined surface 6222 .

[0357] When the second unlocking arm 622 is placed outside the second lower side plate 2023b, the third protrusion 6227 is embedded in the third limiting slot. When the optical module 200 is unlocked, the unlocking member 620b is forced to move leftward, and the third protrusion 6227 moves leftward along the third limiting slot, while the lower housing 202 does not move.

[0358] In some embodiments, referring to Figure 51 , a first limiting protrusion 203b may be provided on the first lower side plate 2022b. The first limiting protrusion 203b protrudes outward from the first lower side plate 2022b and is close to the first recessed area 210, so that the unlocker 620b drives the lower housing 202 to move via the first limiting protrusion 203b.

[0359] 53 , a first limiting hole 6215 may be formed on the first arm 6210. The first limiting hole 6215 is located at one end of the first arm 6210 away from the first connecting portion 624 and is arranged along the length direction (left-right direction) of the first arm 6210.

[0360] In some embodiments, the first limiting protrusion 203b is embedded in the first limiting hole 6215 to install the first support arm 6210 on the first lower side plate 2022b, and the first limiting protrusion 203b is used to limit the first unlocking arm 621b from escaping outward, thereby ensuring the connection between the first unlocking arm 621b and the first lower side plate 2022b.

[0361] In some embodiments, the first limiting hole 6215 has a preset length in the length direction, and the preset length can be the unlocking stroke size of the unlocker 620 b, so as to limit the movement of the first arm 6210 through the first limiting hole 6215 .

[0362] In some embodiments, a limiting hole may be provided on the first lower side plate 2022 b , which is recessed inwardly into the first lower side plate 2022 b and is close to the first recessed area 210 .

[0363] A limiting protrusion may be formed on the first support arm 6210 , and is located on the inner side surface of the first support arm 6210 facing the first lower side plate 2022 b , and the limiting protrusion protrudes toward the inner cavity of the lower housing 202 .

[0364] When the first unlocking arm 621b is installed on the outer side of the first lower side plate 2022b, the limiting protrusion on the first support arm 6210 is embedded in the limiting hole on the first lower side plate 2022b to limit the first unlocking arm 621b from falling out through the limiting protrusion, thereby ensuring the connection between the first unlocking arm 621b and the first lower side plate 2022b.

[0365] In some embodiments, referring to Figure 51 , a second limiting protrusion may be provided on the second lower side plate 2023b. The second limiting protrusion protrudes outward from the second lower side plate 2023b and is close to the third recessed area.

[0366] 53 , a second limiting hole 6225 may be formed on the second arm 6220 . The second limiting hole 6225 is located at an end of the second arm 6220 away from the second connecting portion 625 , and is disposed along the length of the second arm 6220 .

[0367] In some embodiments, the second limiting protrusion is embedded in the second limiting hole 6225 to install the second support arm 6220 on the second lower side plate 2023b, and the second limiting protrusion is used to limit the second unlocking arm 622 from being disengaged, thereby ensuring the connection between the second unlocking arm 622 and the second lower side plate 2023b.

[0368] In some embodiments, the second limiting hole 6225 has a preset length in the length direction, and the preset length can be the unlocking stroke size of the unlocker 620b, so as to limit the movement of the second arm 6220 through the second limiting hole 6225.

[0369] In some embodiments, a limiting hole may be provided on the second lower side plate 2023b, and the limiting hole is recessed inwardly into the second lower side plate 2023b.

[0370] A limiting protrusion may be formed on the second support arm 6220. The limiting protrusion is located on the inner side surface of the second support arm 6220 facing the second lower side plate 2023b, and the limiting protrusion protrudes toward the inner cavity of the lower housing 202.

[0371] When the second unlocking arm 622 is installed on the outer side of the second lower side plate 2023b, the limiting protrusion on the second support arm 6220 is embedded in the limiting hole on the second lower side plate 2023b to limit the second unlocking arm 622 from falling out through the limiting protrusion, thereby ensuring the connection between the second unlocking arm 622 and the second lower side plate 2023b.

[0372] Figure 55 is a partial top view of a lower housing in an optical module according to some embodiments of the present disclosure. As shown in Figure 55, the first limiting protrusion 203b on the first lower side plate 2022b can be a cylindrical protrusion, and the outer side surface of the first limiting protrusion 203b can be a square surface. The first limiting protrusion 203b is inserted into the first limiting hole 6215, and the first unlocking arm 621b is installed on the outer side of the first lower side plate 2022b through the first limiting protrusion 203b, which can effectively prevent the first unlocking arm 621b from falling out of the lower housing 202.

[0373] The second limiting protrusion on the second lower side plate 2023b can be a columnar protrusion, and the outer side surface of the second limiting protrusion can be a square surface. The second limiting protrusion is embedded in the second limiting hole 6225, and the second unlocking arm 622 is installed on the outer side of the second lower side plate 2023b through the second limiting protrusion, which can effectively prevent the second unlocking arm 622 from falling off the lower shell 202.

[0374] In some embodiments, the thickness dimension of the first limiting protrusion 203b can be equal to the width dimension of the first limiting hole 6215, so that the first limiting protrusion 203b can be embedded in the first limiting hole 6215, so that the first limiting hole 6215 can move left and right along both sides of the first limiting protrusion 203b, and at the same time, the first limiting protrusion 203b can prevent the first unlocking arm 621b from falling out of the first lower side plate 2022b.

[0375] The thickness of the second limiting protrusion can be equal to the width of the second limiting hole 6225, so that the second limiting protrusion can be embedded in the second limiting hole 6225, and the second limiting hole 6225 can move left and right along the two sides of the second limiting protrusion. In this way, the second limiting hole 6225 can move left and right along the two sides of the second limiting protrusion, and the second limiting protrusion can prevent the second unlocking arm 622 from falling out of the second lower side plate 2023b.

[0376] In some embodiments, the first limiting protrusion 203b includes a first end and a second end, the first end is away from the first recessed area 210, and the second end is close to the first recessed area 210, the first end has a first thickness dimension H1, and the second end has a second thickness dimension H2, and the first thickness dimension H1 is smaller than the second thickness dimension H2.

[0377] Since the thickness of the first end of the first limiting protrusion 203b is smaller than the thickness of the second end, the outer side surface of the first limiting protrusion 203b facing away from the inner cavity of the lower shell 202 has a first outer side surface 2031 and a second outer side surface 2032. The first outer side surface 2031 is tilted from left to right, and the second outer side surface 2032 is a plane.

[0378] When the first limiting protrusion 203b is inserted into the first limiting hole 6215, the first end of the first limiting protrusion 203b is relatively small, making it easier to insert the first limiting protrusion 203b into the first limiting hole 6215. The second end of the first limiting protrusion 203b is relatively large, so when the unlocking device 620b moves, the second end of the first limiting protrusion 203b can receive the pulling force of the unlocking device 620b and transmit the pulling force to the lower housing 202, thereby facilitating the load-bearing.

[0379] Figure 56 is an assembly diagram of the lower housing and unlocking components in an optical module according to some embodiments of the present disclosure. As shown in Figure 56 , when installing the unlocker 620b onto the side panel of the lower housing 202, the first arm 6210 of the first unlocking arm 621b is positioned outside the first lower side panel 2022b. The first limiting protrusion 203b is inserted into the first limiting hole 6215. The first inclined surface 6211 and the second inclined surface 6212 are positioned within the first recessed area 210 of the first lower side panel 2022b, and the first protrusion 6217 on the second inclined surface 6212 is positioned within the first limiting slot 2029 on the first bearing surface 2030. The first locking hook 6213 is positioned within the first locking slot 2028b.

[0380] Position the second arm 6220 of the second unlocking arm 622 outside the second lower side plate 2023b. Insert the second limiting protrusion into the second limiting hole 6225. Position the third inclined surface 6221 and the fourth inclined surface 6222 within the third recessed area of ​​the second lower side plate 2023b. Position the third protrusion 6227 on the fourth inclined surface 6222 within the third limiting slot of the second lower side plate 2023b. Position the second locking hook 6223 within the second locking slot.

[0381] At this time, the first end of the first limiting protrusion 203b is close to the left end of the first limiting slot 2029, and the right end of the second inclined surface 6212 is against the first connecting surface 2020. The first end of the second limiting protrusion is close to the left end of the third limiting slot, and the right end of the fourth inclined surface 6222 is against the second connecting surface of the second lower side plate 2023b, thereby completing the connection between the unlocker 620b and the lower housing 202.

[0382] Figure 57 illustrates the unlocking process of the lower housing and unlocking component of an optical module according to some embodiments of the present disclosure. As shown in Figure 57 , to unlock the optical module 200, the operator grasps the handle 610b and pulls the unlocker 620b to the left. The first unlocking arm 621b is forced to move leftward. At this point, the lower housing 202 remains stationary, the first limiting hole 6215 moves leftward along the side of the first limiting protrusion 203b, the first protrusion 6217 on the second inclined surface 6212 moves leftward within the first limiting slot 2029, and the first locking hook 6213 moves leftward within the first locking slot 2028b until the right end of the first limiting hole 6215 abuts against the first limiting protrusion 203b.

[0383] When the right end of the first limiting hole 6215 abuts against the first limiting protrusion 203b, and the first unlocking arm 621b continues to move leftward, the first unlocking arm 621b drives the lower shell 202 to move leftward through the first limiting protrusion 203b, so that the lower shell 202 moves leftward.

[0384] Similarly, when the operator grasps the handle 610b and pulls the unlocker 620b to the left, the second unlocking arm 622 is forced to move to the left, the lower shell 202 remains stationary, the second limiting hole 6225 moves to the left along the side of the second limiting protrusion, the third protrusion 6227 on the fourth inclined surface 6222 moves to the left in the third limiting slot, and the second locking hook 6223 moves to the left in the second locking slot until the right end of the second limiting hole 6225 presses against the second limiting protrusion.

[0385] When the right end of the second limiting hole 6225 abuts against the second limiting protrusion, the second unlocking arm 622 continues to move leftward, and the second unlocking arm 622 drives the lower shell 202 to move leftward through the second limiting protrusion, so that the lower shell 202 moves leftward.

[0386] In some embodiments, the unlocker 620b can be non-fixedly connected to the limiting hole and the shell through the limiting protrusion, so that the unlocker 620b can move left and right on the outside of the shell within a certain range to achieve locking and flexible plugging and unplugging of the optical module 200.

[0387] The unlocker 620b can be non-fixedly connected to the shell through other structures. As long as the unlocker 620b can move left and right outside the shell within a certain range, it falls within the protection scope of the embodiments of the present disclosure.

[0388] In some embodiments, the unlocker 620b may be installed on the lower side panel of the lower housing 202. When the optical module 200 is unlocked, the unlocker 620b drives the lower housing 202 to move leftward.

[0389] In some embodiments, the unlocker 620b can be installed on the lower side plate of the lower shell 202 and the upper side plate of the upper shell 201. When the optical module 200 is unlocked, the unlocker 620b drives the lower shell 202 and the upper shell 201 to move to the left to ensure that the optical module 200 is unlocked.

[0390] Figure 58 is a structural diagram of an upper housing in an optical module according to some embodiments of the present disclosure. As shown in Figure 58, the upper housing 201 may include a first upper side panel 2012b. The first upper side panel 2012b is located on one side of the upper housing 201, and the bottom surface of the first upper side panel 2012b covers the top surface of the first lower side panel 2022b.

[0391] The first upper plate 2012b may be formed with a second recessed area 211. The second recessed area 211 is recessed in the first upper plate 2012b and is located above the first recessed area 210. The first recessed area 210 and the second recessed area 211 form a recessed area on the housing.

[0392] The second recessed area 211 may include a fifth side surface 2014b connected to the first upper plate 2012b on one side, and the fifth side surface 2014b is tilted toward the inner cavity of the cavity, that is, the fifth side surface 2014b is tilted from outside to inside.

[0393] The second recessed area 211 may include a sixth side surface 2015b , one side of which is connected to the other side of the fifth side surface 2014b , and the sixth side surface 2015b is disposed along the length direction of the first upper plate 2012b , that is, the sixth side surface 2015b is disposed horizontally.

[0394] The second recessed area 211 may include a second supporting surface 2017b. The second supporting surface 2017b is connected to the top surfaces of the fifth side surface 2014b and the sixth side surface 2015b. The second supporting surface 2017b extends from the fifth side surface 2014b and the sixth side surface 2015b toward the outer side surface of the first upper plate 2012b, and the outer edge of the second supporting surface 2017b is flush with the outer side surface of the first upper plate 2012b.

[0395] In some embodiments, a second limiting slot 2016b may be formed on the second bearing surface 2017b. The second limiting slot 2016b is recessed in the second bearing surface 2017b and has an opening formed on one side of the second limiting slot 2016b facing the lower housing 202.

[0396] 53 , a second protrusion 6216 may be provided on the second inclined surface 6212 . The second protrusion 6216 is located in a direction from the second inclined surface 6212 toward the upper housing 201 , and protrudes from the top surface of the second inclined surface 6212 .

[0397] The second protrusion 6216 can be embedded in the second limiting slot 2016b, so that the first unlocking arm 621b moves outside the first upper side plate 2012b through the second protrusion 6216.

[0398] Similarly, the upper housing 201 may include a second upper side plate 2013b. The second upper side plate 2013b is located at the other side of the upper housing 201, and the bottom surface of the second upper side plate 2013b covers the top surface of the second lower side plate 2023b.

[0399] A fourth recessed area may be formed on the second upper side plate 2013b. The fourth recessed area is recessed in the second upper side plate 2013b and is located above the third recessed area on the second lower side plate 2023b. The fourth recessed area and the third recessed area form a recessed area on the housing.

[0400] The fourth recessed area may include a fourth bearing surface. The outer edge of the fourth bearing surface is flush with the outer side surface of the second upper plate 2013b. A fourth position-limiting slot may be formed on the fourth bearing surface. The fourth position-limiting slot is recessed in the fourth bearing surface and has an opening formed on a side facing the lower housing 202.

[0401] 53 , a fourth protrusion 6226 may be provided on the fourth inclined surface 6222 . The fourth protrusion 6226 is located in a direction from the fourth inclined surface 6222 toward the upper housing 201 and protrudes from the top surface of the fourth inclined surface 6222 .

[0402] The fourth protrusion 6226 can be arbitrarily embedded in the fourth limiting slot, so that the second unlocking arm 622 moves outside the second upper side plate 2013b through the fourth protrusion 6226.

[0403] Figure 59 is a diagram illustrating the assembly structure of an upper housing and an unlocking component in an optical module according to some embodiments of the present disclosure, and Figure 60 is a cross-sectional view of the assembly of the upper housing, lower housing, and unlocking component in an optical module according to some embodiments of the present disclosure. As shown in Figures 59 and 60, when the first unlocking arm 621b is positioned outside the first upper side plate 2012b, the first inclined surface 6211 and the second inclined surface 6212 are positioned within the second recessed area 211, the top surface of the first locking hook 6213 is connected to the bottom surface of the first upper side plate 2012b, and the second protrusion 6216 is embedded in the second limiting slot 2016b, thereby achieving the connection between the first unlocking arm 621b and the first upper side plate 2012b.

[0404] When the second unlocking arm 622 is placed on the outside of the second upper side plate 2013b, the third inclined surface and the fourth inclined surface are placed in the fourth recessed area, the top surface of the second locking hook 6223 is connected to the bottom surface of the second upper side plate 2013b, and the fourth protrusion 6226 is embedded in the fourth limiting slot to realize the connection between the second unlocking arm 622 and the second upper side plate 2013b.

[0405] In this manner, after the upper housing 201 is closed onto the lower housing 202, the unlocking mechanism 620b is placed outside the upper and lower housings 201 and 202, with the first unlocking arm 621b located outside the first upper side plate 2012b and the first lower side plate 2022b, and the first unlocking arm 621b is non-fixedly connected to the first upper side plate 2012b and the first lower side plate 2022b. The second unlocking arm 622 is located outside the second upper side plate 2013b and the second lower side plate 2023b, and the second unlocking arm 622 is non-fixedly connected to the second upper side plate 2013b and the second lower side plate 2023b.

[0406] When the optical module 200 is unlocked, when the unlocker 620b is forced to move to the left, the first protrusion 6217 moves to the left along the first limiting slot 2029, the second protrusion 6216 moves to the left along the second limiting slot 2016b, the third protrusion 6227 moves to the left along the third limiting slot, the fourth protrusion 6226 moves to the left along the fourth limiting slot, the first limiting hole 6215 moves to the left along the first limiting protrusion 203b, and the second limiting hole 6225 moves to the left along the second limiting protrusion. At this time, the upper shell 201 and the lower shell 202 do not move.

[0407] When the unlocker 620b continues to move to the left under the force, the right end of the first limiting hole 6215 abuts against the right end of the first limiting protrusion 203b, and the right end of the second limiting hole 6225 abuts against the right end of the second limiting protrusion. At this time, the unlocker 620b transmits the force to the upper shell 201 and the lower shell 202, so that the unlocker 620b drives the upper shell 201 and the lower shell 202 to move to the left.

[0408] In some embodiments, the length dimension of the first limiting slot 2029 can be the same as the length dimension of the second limiting slot 2016b, and the length dimension of the first limiting slot 2029 and the length dimension of the second limiting slot 2016b can be equal to the length dimension of the first limiting hole 6215.

[0409] The length of the first limiting slot 2029 and the second limiting slot 2016 b may be the same, and the length of the first limiting slot 2029 and the second limiting slot 2016 b may be greater than the length of the first limiting hole 6215 .

[0410] Figure 61 shows a partial assembly diagram of an optical module and a host computer cage according to some embodiments of the present disclosure. Figure 62 shows a cross-sectional view of the lower housing, unlocking component, and host computer cage of an optical module according to some embodiments of the present disclosure. As shown in Figures 61 and 62, the upper housing 201 is placed over the lower housing 202, and the unlocking component 620b is installed on the outer sides of the upper and lower housings 201 and 202 to complete the assembly of the optical module 200. After the optical module 200 is assembled, it is inserted into the cage 106 of the host computer 100.

[0411] Because one end of the unlocker 620b is tilted inward, the first inclined surface 6211 and the second inclined surface 6212 on the first unlocking arm 621b form a first groove, and the third inclined surface 6221 and the fourth inclined surface 6222 on the second unlocking arm 622 form a second groove. When the optical module 200 is inserted into the cage 106, the locking piece 1061 on the cage 106 is embedded in the first groove and the second groove.

[0412] In some embodiments, when the optical module 200 is pulled in a static environment, the locking piece 1061 of the cage 106 is inserted into the unlocker 620 b and the locking piece 1061 presses against the unlocker 620 b, thereby preventing the optical module 200 from falling out of the cage 106 , thereby locking the optical module 200 and the cage 106 .

[0413] When the optical module 200 needs to be removed, the operator grasps the handle 610b and pulls it outward, causing the unlocking mechanism 620b to move leftward under the force, while the upper housing 201 and the lower housing 202 remain stationary. Because the second inclined surface 6212 abuts the fourth inclined surface 6222 and the locking plate 1061, and the second inclined surface 6212 and the fourth inclined surface 6222 are arranged to be inclined from the inside to the outside, when the unlocking mechanism 620b moves leftward, the second inclined surface 6212 and the fourth inclined surface 6222 gradually lift the locking plate 1061 until the locking plate 1061 is released from the first and second grooves of the unlocking mechanism 620b.

[0414] When the locking piece 1061 escapes from the first groove on the unlocker 620b, the right end of the first limiting hole 6215 on the unlocker 620b contacts the first limiting protrusion 203b, and the right end of the second limiting hole 6225 contacts the second limiting protrusion. When the unlocker 620b moves to the left, the external pulling force is transmitted to the upper shell 201 and the lower shell 202. At this time, the upper shell 201, the lower shell 202 and the unlocker 620b move to the left together. Finally, the optical module 200 is unlocked under the action of the external pulling force and escapes from the cage 106.

[0415] After the unlocker 620b moves a certain distance to the left, the locking protrusion on the housing transmits the external pulling force to the housing, causing the unlocker 620b to move leftward along with the housing. However, after unlocking the optical module 200, the unlocker 620b does not reset. When the optical module 200 is reinserted into the host computer 100, the unlocker 620b moves a longer distance.

[0416] Figure 63 is a second partial structural diagram of the lower housing of an optical module according to some embodiments of the present disclosure. Figure 64 is a structural diagram of the lower housing of an optical module according to some embodiments of the present disclosure. As shown in Figures 63 and 64, a first spring slot 207 can be formed on the first lower side plate 2022b. The first spring slot 207 is located on the side of the first lower side plate 2022b away from the first locking slot 2028b. The first spring slot 207 has an opening formed on the side facing away from the inner cavity.

[0417] A first spring 208 may be installed in the first spring slot 207 . One end of the first spring 208 is fixedly mounted on the inner wall of the first spring slot 207 , and the other end of the first spring 208 is movably mounted in the first spring slot 207 .

[0418] Similarly, a second spring slot may be formed on the second lower side plate 2023b. The second spring slot is located on a side of the second lower side plate 2023b away from the second locking slot, and an opening is formed on a side of the second spring slot facing away from the inner cavity.

[0419] A second spring can be installed in the second spring slot. One end of the second spring is fixedly installed on the inner wall of the second spring slot, and the other end of the second spring is movably installed in the second spring slot.

[0420] In some embodiments, a first positioning notch 209 may be formed on the first spring slot 207 . The first positioning notch 209 is located on a side of the first spring slot 207 facing the upper housing 201 , and the first positioning notch 209 is communicated with the first spring slot 207 .

[0421] 58 , the upper housing 201 may be provided with a first positioning post 2018 . The first positioning post 2018 is located on the inner side of the cover 2011 facing the lower housing 202 , close to the first upper side plate 2012 b , and protrudes from the cover 2011 .

[0422] Similarly, a second positioning notch may be formed in the second spring slot. The second positioning notch is located on a side of the second spring slot facing the upper housing 201, and the second positioning notch is communicated with the second spring slot.

[0423] A second positioning post may be provided on the upper housing 201. The second positioning post is located on the inner side of the cover plate 2011 facing the lower housing 202, close to the second upper side plate 2013b, and protrudes from the cover plate 2011.

[0424] When the upper shell 201 is covered on the lower shell 202 , the first positioning post 2018 is inserted into the first positioning notch 209 , and the second positioning post is inserted into the second positioning notch, so as to position and connect the upper shell 201 and the lower shell 202 .

[0425] In some embodiments, when the upper shell 201 and the lower shell 202 are positioned and connected, the positioning columns and positioning notches are not limited to the above-mentioned design methods. As long as the upper shell 201 and the lower shell 202 can be positioned, they all fall within the protection scope of the embodiments of the present disclosure.

[0426] Figure 65 is a second structural diagram of an unlocking mechanism in an optical module according to some embodiments of the present disclosure. As shown in Figure 65 , the first unlocking arm 621b may be provided with a first spring hook 6214. The first spring hook 6214 is located at the junction of the first arm 6210 and the handle 610b, and protrudes toward the interior of the lower housing 202.

[0427] In some embodiments, the first spring hook 6214 can be formed by stamping, by stamping inward from the outer surface of the first arm 6210, with the right end of the first spring hook 6214 protruding toward the inner cavity of the lower shell 202, and the left end of the first spring hook 6214 fixedly connected to the first arm 6210.

[0428] Similarly, a second spring hook 6224 may be provided on the second unlocking arm 622. The second spring hook 6224 is located at the connection between the second arm 6220 and the handle 610b, and the second spring hook 6224 protrudes toward the inner cavity of the lower housing 202.

[0429] The second spring hook 6224 can be formed by stamping, by stamping inward from the outer surface of the second arm 6210, with the right end of the second spring hook 6224 protruding toward the inner cavity of the lower shell 202, and the left end of the second spring hook 6224 fixedly connected to the second arm 6220.

[0430] Figure 66 is a second assembly diagram of the lower housing and unlocking component of an optical module according to some embodiments of the present disclosure. Figure 67 is a second diagram of the unlocking process of the lower housing and unlocking component of an optical module according to some embodiments of the present disclosure. Figure 68 is a second cross-sectional assembly diagram of the upper and lower housings and unlocking component of an optical module according to some embodiments of the present disclosure. As shown in Figures 66, 67, and 68, when the unlocker 620b is installed on the outer sides of the two lower side panels of the lower housing 202, the first spring hook 6214 extends into the first spring slot 207 and engages with the first spring 208. The second spring hook 6224 extends into the second spring slot and engages with the second spring.

[0431] When the optical module 200 is locked with the cage 106, the first spring 208 and the second spring are in a normal state. When the optical module 200 is unlocked from the cage 106, the unlocker 620b is forced to move leftward. At this time, the first spring hook 6214 moves to compress the first spring 208, and the second spring hook 6224 moves to compress the second spring.

[0432] When the unlocker 620b moves to the left, the unlocker 620b gradually pushes up the locking plate 1061 on the cage 106 until the limiting hole on the unlocker 620b abuts against the limiting protrusion on the shell. The unlocker 620b transmits the external pulling force to the shell, and the unlocker 620b drives the shell to move to the left. At this time, the first spring 208 and the second spring are no longer compressed.

[0433] After the optical module 200 is pulled out of the cage 106 , since the first spring 208 and the second spring are in a compressed state, when no external pulling force is applied to the unlocking device 620 b, the unlocking device 620 b is reset under the action of the spring force, so that the optical module 200 can be easily inserted into the cage 106 again.

[0434] In some embodiments, when the upper shell 201 is covered on the lower shell 202 and the unlocker 620b is installed on the outside of the upper shell 201 and the lower shell 202, there may be a gap between the right end of the handle 610b and the left end of the lower shell 202, and the left end of the unlocking arm protrudes from the left end of the lower shell 202 so that the handle 610b can be positioned by the unlocker 620b.

[0435] In some embodiments, the first lower side plate 2022b may be formed with a first positioning groove 212. The first positioning groove 212 is recessed in the first lower side plate 2022b, communicates with the first spring groove 207, and extends from the first spring groove 207 to the lower base plate 2021b.

[0436] When the unlocker 620 b is installed on the outer side of the lower shell 202 , the handle 610 b can be positioned through the first positioning groove 212 to facilitate the positioning and assembly of the handle 610 b and the lower shell 202 .

[0437] In some embodiments, when the outer wall of the shell and the unlocking component 600 are made of relatively hard metal materials, direct contact between the hard materials is considered hard contact. In this way, when the outer wall of the shell and the unlocking component 600 are in hard contact, a gap will be generated between the two, so that the electromagnetic waves radiated from the optical port of the optical module can propagate along the gap.

[0438] To prevent electromagnetic waves from radiating and transmitting along the gap between the outer wall of the housing and the unlocking component 600, as shown in Figure 63, a first shielding portion 206 can be provided on the first lower side plate 2022b. The first shielding portion 206 is located between the first spring slot 207 and the first limiting protrusion 203b and extends from the top to the bottom of the first lower side plate 2022b.

[0439] The first unlocking arm 621b covers the first shielding portion 206, and the first lower plate 2022b and the first unlocking arm 621b are conductively connected through the first shielding portion 206. The first shielding portion 206 is used to seal the gap between the first lower plate 2022b and the first unlocking arm 621b.

[0440] Similarly, the second lower plate 2023b may be provided with a second shielding portion, which is located between the second spring slot and the second limiting protrusion and extends from the upper portion to the bottom portion of the second lower plate 2023b.

[0441] The second unlocking arm 622 covers the second shielding portion, and the second lower side plate 2023b and the second unlocking arm 622 are conductively connected through the second shielding portion. The second shielding portion is used to seal the gap between the second lower side plate 2023b and the second unlocking arm 622.

[0442] In some embodiments, the first shielding portion 206 and the second shielding portion may be conductive pads, or may be rib protrusions on the lower side panel of the lower housing 202 .

[0443] A conductive pad is arranged between the contact point between the outer wall of the shell and the unlocking component 600. The conductive pad is relatively softer than the outer wall of the shell and the unlocking component 600. The conductive pad can achieve conduction between the outer wall of the shell and the unlocking component 600 and can seal the gap between the outer wall of the shell and the unlocking component 600.

[0444] The optical module provided by the embodiment of the present disclosure has a conductive pad provided on the side panel of the shell, and the side panel and the unlocking component 600 are connected by conductive connection through the conductive pad, thereby avoiding the formation of a gap between the side panel and the unlocking component 600, and further avoiding the radiation and propagation of electromagnetic waves from the gap between the side wall of the shell and the unlocking component, thereby improving the electromagnetic shielding effect of the optical module.

[0445] Figure 69 is an exploded view of an unlocking component according to some embodiments. Referring to Figure 69 , in some embodiments, the unlocking component 600 includes an unlocking handle 610 (also referred to as a grip in some examples) and an unlocker 620c. The unlocker 620c has a bottom surface at one end that is recessed toward the top surface to form a mating groove 621c, and a snap-fit ​​component 623 formed on the other end. When the optical module is in a locked state, that is, when the optical module is connected to the host computer, the unlocking handle 610 is in a static state. The static state means that the unlocking handle 610 is in a natural drooping state. The natural drooping state means that the plane where the unlocking handle 610 is located is in a downward state. At the same time, the unlocker 620c is in a horizontal state, and the engaging part 623 is engaged in the cage of the host computer, thereby locking the optical module in the host computer; when the optical module needs to be unlocked, the unlocking handle 610 is pulled upward. During the upward pulling process, the end where the engaging part 623 is located gradually sinks until the engaging part 623 is separated from the cage of the host computer, thereby unlocking the optical module from the host computer.

[0446] Figure 70 is a structural diagram of an unlocking handle according to some embodiments; Figure 71 is a partial structural diagram of an unlocking handle according to some embodiments. As shown in Figures 70 and 71, in some embodiments, the unlocking handle 610 includes a main body structure 611c. When the unlocking handle 610 is pulled upward, the main body structure 611c is pulled to pull the unlocking handle 610. Exemplarily, the main body structure 611c is a U-shaped structure.

[0447] One end of the body structure 611c is formed with a first bend portion 612 and a second bend portion 613 connected to each other. Similarly, the other end of the body structure 611c is formed with a first bend portion 612 and a second bend portion 613 connected to each other. For example, the first bend portion 612 and the second bend portion 613 are both curved, such as being L-shaped. The first bend portion 612 wraps around the limiting portion 2021c to limit the unlocking handle 610 to the lower housing 202.

[0448] The second bending portion 613 at one end is not connected to the second bending portion 613 at the other end, but is disconnected. The first bending portion 612 at one end is connected to the second bending portion 613 at the other end, and a smooth transition is formed between the two.

[0449] A first groove 615 is formed between the first bending portion 612 and the main body structure 611c, and a second groove 616 is formed between the first bending portion 612 and the second bending portion 613. The first groove 615 and the second groove 616 have different directions. For example, the first groove 615 is toward the direction of the lower shell 202, and the first groove 615 wraps the limiting portion 2021c, and the second groove 616 is toward the direction of the upper shell 201.

[0450] A limiting hole 614 is formed on one side of the main structure 611c near the first bent portion 612. The limiting hole 614 is embedded in the surface of the limiting post 2022c. The opening formed between the first bent portion 612 and the main structure 611c wraps around the surface of the limiting portion 2021c, thereby limiting the unlocking handle 610 to the lower housing 202. In some embodiments, when the unlocking handle 610 is pulled upward, it rotates around the limiting post 2022c, thereby driving the rotation of the unlocking mechanism 620c.

[0451] In some embodiments, the second bent portion 613 includes a first connecting portion 6131 and a second connecting portion 6132 connected in a bent manner. For example, the first connecting portion 6131 and the second connecting portion 6132 are not connected in a straight line, but are connected in a bent manner, with the first connecting portion 6131 being arranged in a warped manner relative to the second connecting portion 6132. A connecting surface 6136 is formed at the location where the first connecting portion 6131 and the second connecting portion 6132 are connected.

[0452] In some embodiments, the surface of the first connecting portion 6131 includes a first plane 6133, and the surface of the second connecting portion 6132 includes a second plane 6135. When the unlocking handle 610 is in a stationary state, the first plane 6133 contacts the surface of the mating groove 621c. When the unlocking handle 610 is pulled upward, the second bending portion 613 flips in the mating groove 621c until it flips to the point where the second plane 6135 contacts the surface of the mating groove 621c. During the flipping process, the first plane 6133 gradually flips over from contact with the surface of the mating groove 621c to contact with the second plane 6135 with the surface of the mating groove 621c. To ensure that the engaging component 623 is completely separated from the upper computer, the height of the end where the mating groove 621c is located should be sufficiently raised. The distance between the second plane 6135 and the opposite surface is defined as a first distance, which is L3 marked in Figure 71. The distance between the first plane 6133 and the connecting surface 6136 between the first connecting portion 6131 and the second connecting portion 6132 is defined as a second distance, which is L1 marked in Figure 71. The first distance L3 is greater than the second distance L1, so that the flipping trajectory shows a change in height during the flipping process, and the height of the unlocker 620c also shows a change in height, so that the end where the mating groove 621c is located is raised, and the height of the end where the mating groove 621c is raised is ensured to be sufficient so that the engaging component 623 sinks to a sufficient height to separate from the cage of the upper computer. Exemplarily, the height of one end where the mating groove 621c is located at the beginning of the flip is lower than the height at the end of the flip, and the height of one end where the locking part 623 is located at the beginning of the flip is higher than the corresponding height at the end of the flip, that is, the end where the mating groove 621c is located is raised, and the end where the locking part 623 is located is sunk until the locking part 623 is completely detached from the upper computer and unlocking is successfully achieved.

[0453] The first distance L3 is greater than the second distance L1, resulting in the first connecting portion 6131 having a roughly rectangular shape. For example, when the unlocking handle 610 is at rest, the length of the first connecting portion 6131 along the lower housing 202 is greater than its width. The roughly rectangular shape of the first connecting portion 6131 allows the flipping trajectory to exhibit a change in height during flipping, causing the end where the mating groove 621c is located to rise and the end where the engaging member 623 is located to sink.

[0454] In some embodiments, in order to detach the engaging component 623 from the cage of the host computer, in the process of gradually flipping from the first plane 6133 contacting the surface of the matching groove 621c to the second plane 6135 contacting the surface of the matching groove 621c, the height of the surface of the second plane 6135 contacting the surface of the matching groove 621c is increased compared to when the first plane 6133 is in contact with the surface of the matching groove 621c. For example, when the second plane 6135 is in contact with the surface of the matching groove 621c, the center of the limiting column 2022c is At this time, the distance between the second plane 6135 is greater than the distance between the center of the limit column 2022c and the first plane 6133 when the second plane 6135 contacts the surface of the matching groove 621c. The distance between the two states is the height change shown during the flipping process of the second bending portion 613. The height change is caused by the flipping trajectory of the second bending portion 613. The height change causes the end where the matching groove 621c is located to rise, and the end where the locking part 623 is located to sink, and the sinking height satisfies the locking part 623 to detach from the cage of the upper computer.

[0455] In some embodiments, the surface of the first connecting portion 6131 includes a first flat surface 6133 and an arc segment 6134, and the surface of the second connecting portion 6132 includes a second flat surface 6135. The first flat surface 6133 and the second flat surface 6135 are connected by the arc segment 6134. When the optical module is in the locked state, the first flat surface 6133 is located on the top surface of the first connecting portion 6131, the arc segment 6134 is located on the side surface of the first connecting portion 6131, and the second flat surface 6135 is located on the side surface of the second connecting portion 6132. When the unlocking handle 610 is pulled upward, the second bent portion 613 flips within the mating groove 621c. During the flipping process, the arc segment 6134 and the surface of the mating groove 621c maintain tangential motion. This tangential motion can reduce the flipping friction of the second bent portion 613, thereby improving the smoothness of unlocking.

[0456] The first plane 6133, the arc segment 6134, and the second plane 6135 are connected to form a contact surface. As the unlocking handle 610 rotates, different parts of the contact surface will contact the unlocking device 620c. Similarly, to ensure that the engaging component 623 is completely separated from the upper computer, the distance between the second plane 6135 and the opposite side is the first distance, which is L3 marked in Figure 71. The distance from the first plane 6133 to the connecting surface between the first connecting portion 6131 and the second connecting portion 6132 is the second distance, which is L3 marked in Figure 71. Marked L1, the first distance is greater than the second distance, so that the flipping trajectory shows a change in height during the flipping process, and the height of the unlocker 620c also shows a change in height. For example, the height of the end where the matching groove 621c is located at the beginning of the flip is lower than the height at the end of the flip, and the height of the end where the locking part 623 is located at the beginning of the flip is higher than the corresponding height at the end of the flip, that is, the end where the matching groove 621c is located is lifted, and the end where the locking part 623 is located is sunk until the locking part 623 is completely separated from the upper computer, and the unlocking is successfully achieved.

[0457] The first distance L3 is greater than the second distance L1, and the distance between the arc segment 6134 and the surface opposite it is the third distance L2. The third distance L2 is between the first distance L3 and the second distance L1, so that the first connection portion 6131 has a roughly rectangular shape. For example, when the unlocking handle 610 is stationary, the length of the first connection portion 6131 along the lower shell 202 is greater than its width along the lower shell 202. When the first connection portion 6131 has a roughly rectangular shape, during the rotation of the unlocking handle 610, the dimensions of the unlocking path change, and the height in the later stage of unlocking is greater than the height in the earlier stage of unlocking, thereby raising the end where the mating groove 621c is located and sinking the end where the engaging member 623 is located, thereby achieving unlocking.

[0458] FIG72 is a first structural diagram of an unlocker according to some embodiments; FIG73 is a second structural diagram of an unlocker according to some embodiments. As shown in FIG72 and FIG73, in some embodiments, the bottom surface of one end of the unlocker 620c near the optical port is recessed toward the top surface to form a mating groove 621c. The mating groove 621c covers the surfaces of the second bent portions 613 at both ends, and the ends of the second bent portions 613 extend into the mating groove 621c. The other end of the unlocker 620c is formed with a locking member 623. A through hole 622 is formed in the middle structure of the unlocker 620c. The through hole 622 passes through the connecting shaft 2024c and is rotatable about the connecting shaft 2024c. When the unlocking handle 610 is pulled upward, the unlocker 620c is driven to rotate about the connecting shaft 2024c, causing the end where the locking member 623 is located to sink until the locking member 623 is removed from the cage of the host computer, thereby unlocking the optical module. At this time, the connecting shaft 2024c is located on the lower housing 202, and the connecting shaft 2024c serves as a rotation axis. The lower housing 202 provides a rotation axis for the rotation of the unlocking device 620c. For example, the rotation axis can be provided inside the unlocking device 620c. Accordingly, through holes are formed on both sides of the lower housing 202 to embed the rotation axis. In other words, the unlocking device 620c itself is formed with a rotation axis.

[0459] A protrusion 624 is formed on the side of the unlocker 620c opposite the engaging member 623. A spring 2025c is provided on one side of the connecting shaft 2024c in the lower housing 202. The protrusion 624 is connected to the spring 2025c, thereby connecting the unlocker 620c and the spring 2025c together. When the optical module needs to be unlocked, the end where the engaging member 623 is located presses against the spring 2025c and sinks. When unlocking is complete, the spring 2025c rebounds, causing the unlocker 620c to return to its original position. The spring 2025c also acts as a buffer during the downward movement.

[0460] Figure 74 is a cross-sectional view of an unlocking component according to some embodiments. As shown in Figure 74, in some embodiments, the second bent portions 613 on both sides extend from the bottom end into the two sides of the matching groove 621c, and the unlocking device 620c covers the surfaces of the second bent portions 613 on both sides. For example, one side of the matching groove 621c covers the surface of the second bent portion 613 on one side, and the other side covers the surface of the second bent portion 613 on the other side.

[0461] When the unlocking handle 610 is pulled upward, the second bent portions 613 on both sides rotate and flip within the mating slots 621c, thereby lifting the end of the unlocking device 620c where the mating slots 621c are located and sinking the end where the engaging member 623 is located, thereby unlocking the optical module. Because the second bent portions 613 on both sides need to rotate and flip within the mating slots 621c, there are certain preset requirements for the dimensions of the mating slots 621c. For example, the dimension of the mating slots 621c along the width direction of the lower housing 202 is greater than the distance between the second bent portions 613 on both sides, and the dimension of the mating slots 621c along the length direction of the lower housing 202 is greater than the length of the second bent portions 613, thereby providing sufficient space for the second bent portions 613 to rotate and flip within the mating slots 621c.

[0462] Figure 75 is a cross-sectional view of an optical module according to some embodiments; Figure 76 is a cross-sectional exploded view of an optical module according to some embodiments. As shown in Figures 75 and 76, in some embodiments, the limiting hole 614 of the unlocking handle 610 is embedded in the surface of the limiting column 2022c, and then the first bent portion 612 wraps downwardly around the limiting portion 2021c, thereby limiting the unlocking handle 610 to the lower housing 202; the second bent portion 613 supports the unlocking device 620c upward, so that when the unlocking handle 610 is pulled, the second bent portion 613 rotates to drive the unlocking device 620c to rotate, thereby lifting the end of the unlocking device 620c where the matching slot 621c is located and sinking the end where the engaging member 623 is located, thereby unlocking the optical module. For example, when the unlocking handle 610 is pulled, the unlocking handle 610 rotates with the limiting column 2022c as the fulcrum. In order to prevent the unlocking handle 610 from slipping out of the limiting column 2022c during the rotation, the distance between the outer walls of the limiting columns 2022c on both sides is greater than the distance between the outer walls of the main body structure 611c on both sides, so that the outer wall of the limiting column 2022c protrudes relative to the outer wall of the main body structure 611c, thereby preventing the unlocking handle 610 from slipping out of the limiting column 2022c.

[0463] As shown in Figures 75 and 76, when the optical module is in a locked state, the unlocking handle 610 is in a naturally drooping state. At this time, the unlocker 620c covers the surface of the first plane 6133 on both sides. For example, the mating groove 621c covers the surface of the first plane 6133 on both sides, and the surface of the mating groove 621c is in contact with the first plane 6133.

[0464] In some embodiments, the unlocking handle 610 in Figures 75 and 76 is pulled upward. During the pulling process, the arc segment 6134 remains tangent to the surface of the mating groove 621c, and the second bending portion 613 is rotated with the tangent point formed by the tangency as a fulcrum. During the rotation process, it gradually flips from the first plane 6133 contacting the surface of the mating groove 621c to the second plane 6135 contacting the surface of the mating groove 621c. The flipping trajectory lifts the end of the unlocker 620c where the mating groove 621c is located, and sinks the end where the locking part 623 is located, thereby unlocking the optical module.

[0465] During the unlocking process disclosed herein, when the unlocking handle 610 is pulled upward, the second bent portion 613 is driven to flip its contact surface within the mating groove 621c. The resulting height difference causes the end of the engaging member 623 to sink, thereby unlocking the optical module. During the unlocking process of the second bent portion 613, the arc segment 6134 remains tangent to the surface of the mating groove 621c, thereby reducing friction during the flipping process and ensuring a more consistent force distribution, further enhancing the smoothness of the unlocking process and improving the unlocking experience.

[0466] Figure 77 is a schematic diagram illustrating the unlocking principle of an unlocking component according to some embodiments; Figure 78 is a cross-sectional diagram illustrating the unlocking principle of an unlocking component according to some embodiments. As shown in Figures 77 and 78, the arrows on the left and right sides respectively represent the states corresponding to when the optical module is locked and unlocked. Pulling the unlocking handle 610 upward from the position on the left side of the arrow gradually changes to the state on the right side of the arrow. As can be seen from the state on the right side of the arrow, the end of the unlocker 620c where the mating groove 621c is located rises, and the end where the engaging component 623 is located sinks, thereby unlocking the optical module.

[0467] The left side of the arrow corresponds to the optical module being in a locked state. At this time, the first plane 6133 of the second bent portion 613 contacts the surface of the matching groove 621c, and the unlocker 620c is in a horizontal state. When the optical module needs to be unlocked, the unlocking handle 610 is pulled upward. During the pulling process, the second bent portion 613 is flipped in the matching groove 621c. For example, the arc segment 6134 and the surface of the matching groove 621c are kept tangent. The second bent portion 613 is rotated with the tangent point formed as the fulcrum, and the unlocker 620c is unlocked. 0c is in an inclined state, gradually changing from the first plane 6133 contacting the surface of the mating groove 621c to the arc segment 6134 contacting the surface of the mating groove 621c, and then continuing to rotate and flip until the second plane 6135 contacts the surface of the mating groove 621c. During these changes, the end where the mating groove 621c is located is gradually raised, and the end where the engaging component 623 is located is gradually sunk. The sinking height is sufficient to allow the engaging component 623 to detach from the cage of the host computer, thereby unlocking the optical module. It can be seen that during the process of flipping the second bend 613 to achieve unlocking, the arc segment 6134 remains tangent to the surface of the mating groove 621c, thereby reducing friction during the flipping process, making the force more consistent, thereby increasing the smoothness of unlocking and improving the unlocking experience.

[0468] Figure 79 is a structural diagram of an optical module in a locked state according to some embodiments. As shown in Figure 79, in some embodiments, when the optical module is in the locked state, the unlocker 620c is located on the surface of the first plane 6133 and is pulled upward along the current position of the unlocking handle 610. The arc segment 6134 remains tangent to the surface of the mating groove 621c and rotates and flips around the tangent point until the second plane 6135 contacts the surface of the mating groove 621c. The height change exhibited during this change is caused by the flipping trajectory of the second bent portion 613. This height change causes the end where the mating groove 621c is located to rise and the end where the engaging component 623 is located to sink to a sufficient height to allow the engaging component 623 to detach from the cage of the host computer.

[0469] Figure 80 is a structural diagram of an optical module in an unlocked state according to some embodiments. As shown in Figure 81, in some embodiments, when the optical module is in the unlocked state, the second plane 6135 contacts the surface of the mating slot 621c. If the distance between the first plane 6133 and the side opposite the first plane 6133 is less than the distance between the second plane 6135 and the side opposite the second plane 6135, then during the process of gradually flipping from contact between the first plane 6133 and the surface of the mating slot 621c to contact between the second plane 6135 and the surface of the mating slot 621c, the change in height allows the engaging member 623 to sink sufficiently to disengage from the cage of the host computer, successfully achieving unlocking.

[0470] [Corrected 14.09.2024 according to Rule 91] Figure 81 is a diagram illustrating the unlocking process of an unlocking component according to some embodiments. As shown in Figure 81, in some embodiments, when the optical module is in the locked state, the unlocker 620c is covered on the surface of the first plane 6133, the surface of the mating groove 621c is in contact with the first plane 6133, and the unlocker 620c is in a horizontal state.

[0471] FIG82 is a second diagram illustrating the unlocking process of an unlocking component according to some embodiments. As shown in FIG82 , in some embodiments, when the unlocking handle 610 is gradually pulled upward from its current position in FIG81 , the unlocking member 620c is driven to rotate along the connecting axis 2024c, and the unlocking member 620c begins to tilt, illustratively changing from contact between the first flat surface 6133 and the surface of the mating groove 621c to contact between the arc segment 6134 and the surface of the mating groove 621c. At this point, the engaging member 623 still cannot be released from the cage of the host computer.

[0472] FIG83 is a third diagram illustrating the unlocking process of an unlocking component according to some embodiments. As shown in FIG83 , in some embodiments, as the unlocking handle 610 continues to be gradually pulled upward from its current position in FIG82 , the unlocking member 620c continues to rotate along the connecting axis 2024c. During this process, the arc segment 6134 remains tangent to the surface of the mating groove 621c, and continues to rotate and flip around the tangent point until the second flat surface 6135 contacts the surface of the mating groove 621c. The height change exhibited during this rotation and flipping process is the result of the flipping trajectory of the second bent portion 613. This height change causes the end where the mating groove 621c is located to rise, while the end where the engaging member 623 is located to sink, and the sinking height is sufficient to allow the engaging member 623 to detach from the cage of the host computer.

[0473] According to the unlocking component in the present disclosure, when the unlocking handle is in a naturally drooping state, the plane where the unlocker is located is parallel to the surface of the upper shell, and the first plane contacts the surface of the matching groove. At this time, the unlocker is engaged in the cage of the upper computer, thereby realizing the connection relationship between the optical module and the upper computer; when the unlocking handle is pulled upward, the second bent portion of the unlocking handle flips in the matching groove until the second plane contacts the surface of the matching groove. Since the distance between the second plane and the side opposite to the second plane is greater than the distance between the second plane and the connecting surface, there is a height change in the flipping trajectory during the flipping process. For example, the height of the matching groove at the end of the flipping is higher than the height of the matching groove at the beginning of the flipping. The flipping trajectory of the second bent portion causes one end of the unlocker matching groove to rise and the end where the locking component is located to sink until the locking component is detached from the cage of the upper computer, thereby releasing the connection relationship between the optical module and the upper computer and realizing the unlocking of the optical module. In the present disclosure, a second bend is formed at the end of the unlocking handle. By flipping the second bend in the matching groove, since the distance between the second plane and the side opposite to the second plane is greater than the distance between the second plane and the connecting surface, the second bend is approximately rectangular at this time, and the flipping trajectory shows a change in height, thereby causing the end where the locking component is located to sink until it is separated from the cage of the host computer, successfully achieving unlocking. In the present disclosure, by flipping the second bend, which is approximately rectangular, the trajectory shows a change in height, thereby achieving unlocking. At the same time, the trajectory is smooth during the unlocking process, thereby improving the smoothness of unlocking the optical module and enhancing the unlocking experience.

[0474] FIG84 is a structural diagram of an optical network terminal cage according to some embodiments. As shown in FIG84 , in some embodiments, a cage of a host computer, such as cage 106 of optical network terminal 100, has a spring clip 1061 at its port that mates with the engaging component of unlocking component 400. Spring clip 1061 includes a fixed end and a free end. The fixed end is fixed to cage 106, while the free end is movable. A card interface 1062 is defined on the surface of the free end, which mates with engaging component 318. When engaging component 318 with card interface 1062, electrical port module 300 (also referred to as an optical module in some examples) is secured to the host computer, thereby locking electrical port module 300. When engaging component 318 with card interface 1062, electrical port module 300 is released from host computer, thereby unlocking electrical port module 300.

[0475] In some embodiments, when the spring clip 1061 remains relatively stationary, its free end is tilted relative to the fixed end, and the surface of the spring clip 1061 is an inclined surface. The inclined spring clip 1061 is more conducive to unlocking the electrical port module 300 than the flat spring clip.

[0476] When unlocking the electrical port module 300, there are many ways to release the engagement between the electrical port module 300 and the host computer. In some embodiments, the host computer cage is kept relatively fixed, and the locking member 318 is lowered, so that the electrical port module 300 actively disengages from the spring 1061, thereby separating the electrical port module 300 from the host computer. In some embodiments, the locking member 318 is kept relatively fixed, and the spring 1061 is pushed upward, so that the electrical port module 300 passively disengages from the spring 1061, thereby separating the electrical port module 300 from the host computer. In the present disclosure, since the locking member 318 is provided on the surface of the upper housing 310 and not on the surface of the unlocker 420, in some embodiments, the locking member 318 can be kept relatively fixed, and the spring 1061 is pushed upward, thereby achieving unlocking of the electrical port module 300.

[0477] In some embodiments, when the unlocking handle 410 remains in a naturally drooping state, the unlocker 420 remains relatively stationary, and there is a certain distance between the unlocker 420 and the locking component 318. The unlocker 420 cannot act on the locking component 318 and the spring 1061, and cannot separate the two, thereby keeping the electrical port module 300 in a locked state.

[0478] In some embodiments, when unlocking the electrical port module 300, when the unlocking handle 410 is pulled upward in the direction of the upper shell 310, the unlocker 420 can slide along the upper shell 310 toward the locking component 318 and the spring piece 1061 under the action of the thrust, and the sliding unlocker 420 gradually approaches the locking component 318 and the spring piece 1061, and then gradually pushes up the spring piece 1061 until the spring piece 1061 is disengaged from the locking component 318, thereby unlocking the electrical port module 300.

[0479] FIG85 is a structural diagram of an unlocking component according to some embodiments. As shown in FIG85 , in some embodiments, the unlocking component 400 includes an unlocking handle 410 and an unlocking mechanism 420 connected to each other. The unlocking handle 410 is rotatably connected relative to the upper housing 310, and the unlocking mechanism 420 is slidably connected relative to the upper housing 310. When the unlocking handle 410 is pulled upward along the sidewall of the upper housing 310, the unlocking handle 410 rotates relative to the upper housing 310. During the rotation of the unlocking handle 410, the unlocking mechanism 420 is driven to move along the first guide rail 313 and the second guide rail 314 toward the engaging member 318 and the spring 1061. The gradually moving unlocking mechanism 420 slowly acts on the spring 1061, slowly lifting the spring 1061 until the spring 1061 is disengaged from the engaging member 318. The engaging member 318 is passively disengaged from the spring 1061, thereby unlocking the electrical port module 300.

[0480] In some embodiments, in order to limit the unlocking handle 410 to the side wall of the upper shell 310, a first nesting hole 414 and a second nesting hole 415 are respectively formed on both sides of the surface of the unlocking handle 410. The first nesting hole 414 is nested on the first rotating axis 315, and the second nesting hole 415 is nested on the second rotating axis 316, thereby limiting the unlocking handle 410 to the side wall of the upper shell 310 and being rotatable along the first rotating axis 315 and the second rotating axis 316.

[0481] In some embodiments, the unlocker 420 includes a main body structure 421 disposed between the first flat plate 311 and the second flat plate 312. To ensure that the unlocker 420 is pushed toward the engaging member 318 and the spring 1061 when the unlocking handle 410 is rotated, a boss 411 is formed on the surface of the unlocking handle 410. The boss 411 is disposed between the first nesting hole 414 and the second nesting hole 415. When the unlocking handle 410 is rotated, the boss 411 rotates accordingly. During the rotation of the boss 411, the boss 411 applies a thrust to the end surface of the main body structure 421, thereby pushing the unlocker 420 to move, causing the unlocker 420 to gradually approach the engaging member 318 and the spring 1061, thereby acting on the spring 1061 and lifting it, thereby unlocking the electrical port module 300. For example, in order to increase the smoothness of the force applied when the boss 411 rotates to push the unlocker 420 to move, the surface of the boss 411 in contact with the unlocker 420 is a smooth curved surface, thereby reducing the friction between the two and increasing smoothness.

[0482] In some embodiments of the present disclosure, when the boss 411 cooperates with the main body structure 421, whether the surfaces of the boss 411 and the main body structure 421 are flush affects the compatibility. Due to processing errors and assembly errors, there is a certain height difference between the boss 411 and the surface of the unlocker 420, which affects the interaction between the two. When the contact area between the boss 411 and the unlocker 420 is large, this effect is particularly obvious. At the same time, when the contact area between the boss 411 and the main body structure 421 is large, the force is more dispersed, which is not conducive to generating an effective unlocking stroke. Therefore, in some embodiments, the end of the main body structure 421 extends the first arm 422 toward the unlocking handle 410. In order to cooperate with the first arm 422, a surface of the boss 411 is recessed to form a notch 412. The notch 412 rotates as the unlocking handle 410 rotates. As the notch 412 rotates, the notch 412 squeezes the first arm 422. Under the squeezing, the first arm 422 slides along the inside of the notch 412. When the first arm 422 slides out of the notch 412, it continues to be abutted by the side wall 418 connected to the notch 412, causing the first arm 422 to move toward the engaging component 318, thereby pushing the unlocker 420 to move toward the position where the spring piece 1061 is located, generating a certain unlocking stroke. The contact area between the first arm 422 and the notch 412 is relatively smaller than the contact area between the boss 411 and the main structure 421, thereby reducing the impact of uneven surfaces of the boss 411 and the main structure 421 on their interaction. At the same time, the force acting on the active surface between the first arm 422 and the notch 412 is more concentrated, facilitating an effective unlocking stroke. Furthermore, due to the provision of the notch 412, when the electrical port module 300 is in the locked state, the unlocker 420 is closer to the unlocking handle 410 and, therefore, further away from the engaging component 318 and the spring 1061. As a result, the unlocker 420 does not act on the spring 1061, thereby preventing the engagement between the spring 1061 and the engaging component 318 from being disrupted, thereby maintaining the electrical port module 300 in the locked state.

[0483] When the notch 412 is L-shaped, it has better openness, so that at the moment when the notch 412 and the first arm 422 are separated, the unlocker 420 can be separated from the notch 412 and is no longer restricted by the notch 412.

[0484] In some embodiments, to ensure that the electrical port module 300 is in a locked state, a certain distance should be maintained between the unlocker 420 and the spring 1061. Otherwise, the electrical port module 300 will be unlocked, destroying the current locked state. For example, when the electrical port module 300 is in a locked state, a longer distance is maintained between the unlocker 420 and the spring 1061. To ensure that the longer distance between the unlocker 420 and the spring 1061 is maintained when the electrical port module 300 is in a locked state, the first arm 422 is shorter. This shortens the relative length of the unlocker 420 when the electrical port module is in a locked state, thereby lengthening the distance from the spring 1061 and avoiding acting on the spring 1061, thereby maintaining the locked state of the electrical port module. Correspondingly, the notch 412 is located on the side of the boss 411 facing the engaging component 318, and the notch 412 is relatively closer to the engaging component 318.

[0485] In some embodiments, sufficient unlocking travel should be provided when unlocking the electrical port module 300 so that the unlocker 420 can completely lift the spring 1061, thereby completely disengaging the spring 1061 from the engaging member 318 and achieving successful unlocking. When the first arm 422 is a short arm, when the unlocking handle 410 is pulled to a certain height, the notch 412 and the first arm 422 will be offset from each other and no longer in contact. The first arm 422 is no longer squeezed, and no further unlocking travel will be generated. For example, at a certain moment, the first arm 422 will be disengaged from the notch 412, and the two will lose contact, so that the notch 412 no longer pushes the first arm 422 to generate the unlocking travel.

[0486] In some embodiments, to generate a continuous and sufficient unlocking stroke, a surface of the boss 411 opposite to the surface where the notch 412 is located is recessed to form a groove 413. For example, one surface of the boss 411 is recessed toward the interior of the boss 411 to form the notch 412, and the other surface of the boss 411 is also recessed toward the interior of the boss 411 to form the groove 413. The groove 413 and the notch 412 are located diagonally to each other in the boss 411, and the groove 413 is further away from the engaging component 318 than the notch 412. The recesses 413 and the notch 412 are arranged in opposite directions, and the openings of the groove 413 and the notch 412 are oriented in different directions. For example, the opening of the notch 412 is toward the side where the engaging component 318 is located, and the opening of the groove 413 is away from the side where the engaging component 318 is located. To match the groove 413, a second arm 423 extends from the end surface of the main body structure 421 facing the unlocking handle 410. To facilitate extension, the second arm 423 extends from the side wall of the main body structure 421 and is located on the side edge of the main body structure 421. Because the groove 413 is farther from the engaging member 318 than the notch 412, that is, the groove 413 is farther from the main body structure 412 than the notch 412, the second arm 423 extends from the side wall of the main body structure 421. The end of the second arm 423 is bent to form a bent portion 424. The second arm 423 is relatively long, illustratively having a predetermined length so that the bent portion 424 extends beyond the side of the boss 411 until it reaches the location of the groove 413, thereby extending the bent portion 424 to the groove 413. Exemplarily, the second arm 423 is connected to the bent portion 424 by bending, and the end of the second arm 423 is bent inward to form the bent portion 424 .

[0487] The groove 413 is farther away from the locking part 318 than the notch 412. Correspondingly, the bent portion 424 is farther away from the locking part 318 than the first arm 422. The second arm 423 extends the bent portion 424 at the end to the position of the groove 413, so that the groove 413 interacts with the bent portion 424, and the notch 412 interacts with the first arm 422. Since the notch 412 is closer to the groove 413, the length of the first arm 422 is relatively shorter than the length of the second arm 423.

[0488] As the unlocking handle 410 rotates, the notch 412 rotates accordingly, and the rotating notch 412 squeezes the first arm 422, thereby pushing the first arm 422 to move. Since the length of the first arm 422 is relatively short, for example, the length of the first arm 422 is less than the length of the second arm 423, the first arm 422 and the notch 412 will be disconnected due to mutual offset during the rotation of the notch 412, and the first arm 422 and the side wall 418 will also be disconnected due to mutual offset. At this time, the first arm 422 is no longer under force, and the unlocking device 420 cannot be moved further. In order to completely push up the spring piece 1061 and completely disengage the spring piece 1061 from the engaging component 318, the present invention When the lock is unlocked, the first arm 422 is unlocked and the second arm 423 is unlocked. When the lock is unlocked, the first arm 422 is unlocked and the second arm 423 is unlocked. When the lock is unlocked, the first arm 422 is unlocked and the second arm 423 is unlocked.

[0489] In the present disclosure, the first arm 422 is squeezed by the notch 412 as the unlocking handle 410 begins to rotate, driving the main structure 421 to move. During the movement of the first arm 422, the bent portion 424 enters the groove 413. At this point, the bent portion 424 is squeezed by the groove 413, driving the second arm 423 to move. The movement of the second arm 423 then drives the main structure 421 to move. In the present disclosure, the forces acting on the first arm 422 and the bent portion 424 continuously generate an unlocking stroke, thereby increasing the unlocking stroke and achieving complete unlocking. The first arm 422 is relatively short, and the second arm 423 extends laterally over the boss 411. This design allows the first and second arms 422, 423 to be more centrally located, facilitating miniaturization. Furthermore, when in the locked state, the first and second arms 422, 423 maintain a distance from the engaging member 318, preventing them from acting on the spring and disrupting the locked state. If unlocking is performed only through the first arm 422, the first arm 422 is long, which is not conducive to miniaturization and cannot be kept at a large distance from the engaging member 318. If unlocking is performed only through the second arm 423, the second arm 423 will be subjected to force at the beginning of the rotation of the unlocking handle 410, which is not conducive to generating a long unlocking stroke. The present disclosure generates a progressive unlocking stroke by progressively applying force to the shorter first arm 422 and the second arm 423 extending from the side, providing a continuous and sufficient unlocking stroke. The present disclosure has an ingenious design that facilitates miniaturization and produces a long unlocking stroke, thereby achieving complete unlocking. In some embodiments, progressive unlocking can be achieved when the first arm 422 stops being subjected to force and the bent portion 424 is subjected to force. In some embodiments, progressive unlocking can also be achieved when the bent portion 424 begins to be subjected to force before the first arm 422 stops being subjected to force.

[0490] The shape of the groove 413 can be U-shaped, with good wrapping properties to prevent the bending portion 424 from slipping out of the groove 413, increasing the moving time of the bending portion 424 in the groove 413, thereby generating a longer unlocking stroke and achieving complete unlocking of the electrical port module 300.

[0491] When the electrical port module 300 is locked, the bent portion 424 does not contact the groove 413, maintaining the locked state of the electrical port module 300. When the unlocking handle 410 is rotated to a certain height, the bent portion 424 begins to contact the groove 413. As the unlocking handle 410 rotates, the compression between the groove 413 and the bent portion 424 pushes the unlocker 420 toward the engaging member 318 and the spring 1061, thereby increasing the unlocking stroke and providing a continuous and sufficient unlocking stroke until the spring 1061 is completely lifted, disengaging the electrical port module from the host computer.

[0492] Figure 86 is a structural diagram 1 of an unlocking handle according to some embodiments; Figure 87 is a structural diagram 2 of an unlocking handle according to some embodiments. As shown in Figures 86 and 87, in some embodiments, the unlocking handle 410 includes a fixed end and a free end, and the fixed end is fixed to the upper shell 310. The fixed end is the end of the unlocking handle 410 that is connected to the upper shell 310, and a notch 412 and a groove 413 are formed on both sides of the end, respectively. The free end of the unlocking handle 410 is freely set relative to the upper shell 310. When the free end is pulled upward, the unlocking handle 410 rotates along the side wall of the upper shell 310. The boss 411 is at the fixed end of the unlocking handle 410. The notch 412 and the groove 413 are respectively provided on two different surfaces of the boss 411. Exemplarily, the notch 412 is further away from the engaging component than the groove 413.

[0493] To secure the unlocking handle 410 to the sidewall of the upper housing 310, a first nesting hole 414 and a second nesting hole 415 are formed on either side of the surface of the fixed end of the unlocking handle 410. The first nesting hole 414 nests with the first rotation axis 315, and the second nesting hole 415 nests with the second rotation axis 316. This secures the unlocking handle 410 to the sidewall of the upper housing 310 while allowing the unlocking handle 410 to rotate along the first and second rotation axes 315 and 316. To avoid certain structures, a first avoidance portion 416 is formed on one side of the second nesting hole 415, and a second avoidance portion 417 is formed on one side of the first nesting hole 414.

[0494] In some embodiments, in order to increase the smoothness of unlocking, the notch 412 includes a first accommodating cavity 4121 and a first rounded corner 4122. The first accommodating cavity 4121 is used to accommodate the first arm 422. The first rounded corner 4122 is located at the top of the first accommodating cavity 4121. As the unlocking handle 410 rotates, the opening of the notch 412 rotates downward. During the rotation, the first rounded corner 4122 contacts the first arm 422, and the inner wall of the notch 412 squeezes the first arm 422. During the pulling process, the first rounded corner 4122 acts tangentially to the first arm 422, and the tangent point of the two is used as a fulcrum, thereby pushing the unlocker 420 forward. "Pushing the unlocker 420 forward" means pushing the unlocker 420 in the direction of the locking component 318 and the spring piece 1061. When the first fillet 4122 separates from the first arm 422, the sidewall 418 connected to the notch 412 abuts the first arm 422 until the sidewall 418 separates from the first arm. The first arm 422 is no longer subjected to force and is unable to move the main body structure. Due to the smooth surface of the first fillet 4122, the tangential friction between the first fillet 4122 and the first arm 422 facilitates smoother movement, thereby facilitating a smoother unlocking process.

[0495] In some embodiments, in order to increase the smoothness of unlocking, the groove 413 includes a second accommodating cavity 4131, a second rounded corner 4132 and a curved surface 4133. As the unlocking handle 410 rotates, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424. The curved surface 4133 squeezes the bent portion 424, thereby pushing the bent portion 424 toward the second rounded corner 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second rounded corner 4132, and the two also move tangentially. , using the tangent point of the two as a fulcrum, move the bent portion 424 toward the second accommodating cavity 4131, and the second accommodating cavity 4131 squeezes the bent portion 424, so that the bent portion 424 pushes the unlocker 420 toward the locking component 318 and the spring piece 1061 until the unlocker 420 completely lifts the spring piece 1061 and completely separates the spring piece 1061 from the locking component 318, thereby releasing the locking relationship between the electrical port module 300 and the host computer, separating the electrical port module 300 from the host computer, and unlocking the electrical port module 300.

[0496] In some embodiments, to ensure that the notch 412 compresses the first arm 422 to produce an unlocking stroke, the inner wall dimension of the notch 412 along the height direction of the upper shell 310 is greater than the inner wall dimension of the notch 412 along the length direction of the upper shell 310. Specifically, the inner wall dimension of the notch 412 along the height direction of the upper shell 310 is indicated by line segment H in FIG. 86 , and the inner wall dimension of the notch 412 along the length direction of the upper shell 310 is indicated by line segment L in FIG. 86 . When the length of line segment H is greater than the length of line segment L, rotation of the notch 412 can cause the first arm 422 to move, resulting in a certain unlocking stroke. In some embodiments, the notch 412 is L-shaped, comprising a vertical inner wall and a horizontal inner wall. For example, the vertical inner wall is larger than the horizontal inner wall, thereby pushing the first arm 422 to slide forward.

[0497] Figure 88 is a structural diagram of an unlocker according to some embodiments; Figure 89 is a structural diagram of an unlocker according to some embodiments; and Figure 90 is a cross-sectional structural diagram of an unlocker according to some embodiments. As shown in Figures 88-90, in some embodiments, the bent portion 424 is a hemispherical arm. The top surface of the bent portion 424 is flat, and a hemispherical surface is formed downwardly around the top surface. This allows the force-bearing surface between the bent portion 424 and the groove 413 to be more concentrated, avoiding the presence of other force-bearing surfaces.

[0498] In some embodiments, both the second arm 423 and the first arm 422 extend relative to the end surface of the main structure 421. For example, the relative extension length of the second arm 423 is greater than the relative extension length of the first arm 422. The longer extension length of the second arm 423 ensures that the bent portion 424 passes over the side of the boss 411 and extends to the groove 413. The relative extension length of the second arm 423 is represented by line segment n in Figure 9, and the relative extension length of the first arm 422 is represented by line segment m in Figure 88. Clearly, the length of line segment n is greater than the length of line segment n. The present disclosure utilizes two arms with different extension lengths to create a progressive unlocking path, which facilitates miniaturization while providing a longer unlocking stroke.

[0499] In some embodiments, the first arm 422 and the bent portion 424 extend in different directions. The first arm 422 extends in the same direction as the length of the main body structure 421 , while the bent portion 424 extends in the same direction as the width of the main body structure 421 .

[0500] In some embodiments, the lengths of the first arm 422 and the second arm 423 can be designed according to the expected unlocking stroke, so as to achieve the expected unlocking stroke and realize complete unlocking of the electrical port module 300.

[0501] In some embodiments, in order to allow the unlocker 420 to slide along the upper shell 310 and thus move toward the locking component 318 and the spring 1061, a first sliding groove 426 and a second sliding groove 425 are respectively formed on both sides of the main body structure 421. As mentioned above, the surface of one end of the upper shell 310 close to the optical port is disconnected to form a first flat plate 311 and a second flat plate 312 on both sides, respectively. The first flat plate 311 and the second flat plate 312 are arranged opposite to each other and are not connected. There is a gap 319 between the two, and the gap 319 is used to accommodate the unlocker 420. A first guide rail 313 is formed on the side wall of the first plate 311 facing the gap 319, and a second guide rail 314 is formed on the side wall of the second plate 312 facing the gap 319. A first guide groove 426 is slidably connected to the first guide rail 313, and a second guide groove 425 is slidably connected to the second guide rail 314. Therefore, when the unlocking handle 410 is pulled upward, the first guide groove 426 slides along the first guide rail 313 toward the engaging member 318 and the spring 1061, and the second guide groove 425 slides along the second guide rail 314 toward the engaging member 318 and the spring 1061. This causes the unlocking mechanism 420 to act on the surface of the spring 1061, lifting it, thereby unlocking the electrical port module 300. For example, the lengths of the first guide groove 426 and the second guide groove 425 depend on the unlocking stroke required to unlock the electrical port module 300.

[0502] When the electrical port module 300 is locked, a certain distance must be maintained between the electrical port module 300 and the engaging member 318 to prevent it from being unlocked. Therefore, the unlocker 420 must have a predetermined length. To ensure a sufficient unlocking stroke, the first and second slide slots 426 and 425 must each have a predetermined length. This leaves a limited length for the first arm 422, and the end of the first arm 422 is connected to the surface of the boss 411. Therefore, the first arm 422 is located between the boss 411 and the main body 421. This results in a relatively short length for the first arm 422. Furthermore, the unlocker 420 must be relatively close to the unlocking handle 410 to extend the distance between the unlocker 420 and the engaging member 318 when the electrical port module 300 is locked. Therefore, the length of the first arm 422 cannot be too long, both from a mechanical perspective and from the unlocking principle.

[0503] In some embodiments, one end of the main body structure 421 is respectively formed with a first arm 422 and a bent portion 424, and the other end is formed with a connecting plane 428. The two ends of the connecting plane 428 are respectively formed with a first inclined surface 429a and a second inclined surface 429b. When it is necessary to unlock the electrical port module 300, the unlocking handle 420 is rotated, and at the same time, the unlocker 420 is driven to move toward the position where the engaging component 318 and the elastic piece 1061 are located. Then, the first inclined surface 429a and the second inclined surface 429b are also moved toward the position where the engaging component 318 and the elastic piece 1061 are located. During the movement, the first inclined surface 429a and the second inclined surface 429b are respectively in contact with the two sides of the elastic piece 1061, and the thrust applied by the unlocking handle 410 acts on the first inclined surface 429a and the second inclined surface 429b. On the inclined surface 429b, according to the decomposition of the acting force, the thrust on the first inclined surface 429a and the second inclined surface 429b can be decomposed into a horizontal component and a vertical component that are perpendicular to each other. Under the action of the horizontal component, the unlocker 420 moves forward, and under the action of the vertical component, the spring piece 1061 is pushed upward. As the unlocking handle 410 rotates, the unlocker 420 is pushed forward. During the pushing process, the first inclined surface 429a and the second inclined surface 429b contact the spring piece 1061 and act on the spring piece 1061. The contact surface between the two inclined surfaces and the spring piece 1061 gradually rises as the unlocker 420 moves forward. The free end of the spring piece 1061 can be lifted by the gradually raised contact surface until the spring piece 1061 is disengaged from the engaging component 318. Meanwhile, illustratively, the first inclined surface 429 a and the second inclined surface 429 b are not connected and have a certain gap therebetween so as to avoid the engaging component 318 when the engaging component 318 is released.

[0504] In some embodiments, the spring clip 1061 is in an inclined state. For example, the height of the free end of the spring clip 1061 is higher than the height of the fixed end of the spring clip 1061. In order to make the first inclined surface 429a and the second inclined surface 429b contact the spring clip 1061 from their bottom, thereby acting on the spring clip 1061, the height of the connecting plane 428 should be lower than the height of the main body structure 421, so that the surface where the first inclined surface 429a and the second inclined surface 429b are located is sunken, so that the first inclined surface 429a and the second inclined surface 429b are respectively in contact with the spring clip 1061 from the beginning, extending the contact time with the spring clip 1061, thereby ensuring that the spring clip 1061 is effectively lifted up and completely lifted up until the spring clip 1061 is disengaged from the locking component 318, thereby unlocking the electrical port module 300 from the host computer. To this end, a connecting bevel 427 is connected between the main body structure 421 and the connecting plane 428. The connecting bevel 427 connects the main body structure 421 and the connecting plane 428, thereby ensuring effective action on the spring piece 1061. For example, the connecting bevel 427 is arranged at an angle so that the surface of the main body structure 421 is higher than the surface of the connecting plane 428. The inclination angle of the connecting bevel 427 can be determined according to the position of the engaging member 318.

[0505] FIG91 is a structural diagram of an upper housing according to some embodiments. As shown in FIG91 , in some embodiments, a first rotating shaft 315 is formed on one side of the first flat plate 311, and a second rotating shaft 316 is formed on one side of the second flat plate 312. The first rotating shaft 315 and the second rotating shaft 316 are both bent and extended relative to the side wall of the upper housing 310. For example, the two extend in the same direction to facilitate the nesting of the unlocking handle 410. In order to limit the unlocking handle 410, a limiting groove 3161 is formed on the second rotating shaft 316, and a limiting structure is provided on the surface of the limiting groove 3161 to limit and fix the unlocking handle 410. For example, the limiting structure can be a limiting plate.

[0506] FIG92 is a cross-sectional view of an electrical port module according to some embodiments. As shown in FIG92 , in some embodiments, the main body structure 421 of the unlocker 420 is disposed between the first plate 311 and the second plate 312. A first guide rail 313 is formed on the side wall of the first plate 311 facing the gap 319, and a second guide rail 314 is formed on the side wall of the second plate 312 facing the gap 319. A first slide groove 426 and a second slide groove 425 are formed on both sides of the main body structure 421, respectively. The first slide groove 426 is slidably connected to the first guide rail 313, and the second slide groove 425 is slidably connected to the first guide rail 313. The two slide grooves 425 are slidably connected to the second guide rail 314. Therefore, when the unlocking handle 410 is pulled upward, under the action of the thrust, the first slide groove 426 slides along the first guide rail 313 toward the engaging component 318 and the spring piece 1061, and the second slide groove 425 slides along the second guide rail 314 toward the engaging component 318 and the spring piece 1061, so that the unlocker 420 acts on the surface of the spring piece 1061, pushing up the spring piece 1061, thereby unlocking the electrical port module 300.

[0507] Figure 93 is a structural diagram of an electrical port module end according to some embodiments. As shown in Figure 93, in some embodiments, to limit the unlocking handle 410, a limiting groove 3161 is formed on the second rotating shaft 316, and a limiting piece 317 is provided on the surface of the limiting groove 3161 to limit the unlocking handle 410 on the upper housing 310 and prevent the unlocking handle 410 from slipping out of the upper housing 310.

[0508] A first avoidance portion 416 is formed on one side of the second nesting hole 415 for avoiding the limiting piece 317 ; a second avoidance portion 417 is formed on one side of the first nesting hole 414 for avoiding the side wall of the upper shell 310 .

[0509] FIG94 illustrates the unlocking process of an unlocking component according to some embodiments. As shown in FIG94 , in some embodiments, when the unlocking handle 410 is rotated upward, the unlocking handle 410 pushes the unlocking member 420 forward to approach the engaging member 318 and the spring 1061. The unlocking member 420 contacts both sides of the spring 1061 through its first inclined surface 429a and second inclined surface 429b, respectively. As the unlocking member 420 moves forward, the first inclined surface 429a and second inclined surface 429b gradually act on the spring 1061. The gradually rising contact surface lifts the free end of the spring 1061 until the spring 1061 is disengaged from the engaging member 318, thereby unlocking the electrical port module 300. The "forward movement" refers to the unlocking member 420 moving toward the position of the engaging member 318.

[0510] When the unlock handle 410 is in its naturally drooping position, the electrical port module 300 is inserted into the cage of the host computer. Since the unlocking mechanism 420 is far away from the spring 1061, it cannot act on the spring 1061, thus maintaining the locked state of the electrical port module 300. When the unlock handle 410 is pulled to a higher height, the unlocking mechanism 420 contacts and acts on the spring 1061 until it lifts up, unlocking the electrical port module 300.

[0511] FIG95 is a first diagram illustrating the unlocking principle of an unlocking component according to some embodiments. FIG95 illustrates the interaction between the notch 412 and the first arm 422 during the unlocking process of rotating the unlocking handle 410. Before the unlocking handle 410 is pulled, the first arm 422 is positioned within the notch 412 to maintain the stability of the unlocking mechanism 420. As the unlocking handle 410 is gradually lifted, the opening of the notch 412 gradually moves downward. During this movement, the first rounded corner 4122 of the notch 412 supports the first arm 422 as it moves forward. The notch 412 exerts pressure on the first arm 422, causing it to move forward until it is free of the notch 412. The arm 422 is then abutted against the sidewall 418 and moves forward. When the first arm 422 is no longer in contact with the sidewall 418, it is no longer compressed and can no longer push forward. For example, the notch 412 and the first arm 422 may be disconnected at some point due to vertical misalignment, such as the first arm 422 being located obliquely above the notch 412 , and thus the unlocker 420 cannot be pushed forward any further.

[0512] Figure 96 is a second schematic diagram of the unlocking principle of an unlocking component according to some embodiments. Figure 96 illustrates the interaction between the groove 413 and the bent portion 424 during the unlocking process when the unlocking handle 410 is pulled. Before the unlocking handle 410 is pulled, the groove 413 and the bent portion 424 must not come into contact with each other, otherwise the electrical port module 300 will be unlocked to a certain extent, destroying the locked state of the electrical port module 300. When the unlocking handle 410 is gradually lifted, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424, pushing the bent portion 424 toward the second rounded corner 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second rounded corner 4132, and the two also make tangential motions. With the tangent point of the two as the fulcrum, the bent portion 424 is moved toward the second accommodating cavity 4131. The rotating second accommodating cavity 4131 squeezes the bent portion 424, thereby causing the second support arm 423 to move forward, and at the same time drives the main body structure 421 to move until the unlocking device 420 completely lifts the spring piece 1061, completely disengaging the spring piece 1061 from the engaging component 318, thereby releasing the engaging relationship between the electrical port module 300 and the host computer, disengaging the electrical port module 300 from the host computer, and unlocking the electrical port module 300.

[0513] In some embodiments, as the unlocking handle 410 is gradually lifted, the curved surface 4133 begins to contact the bent portion 424. At this time, the first arm 422 is still connected to the notch 412, that is, the time point when the notch 412 is disconnected from the first arm 422 is later than the time point when the curved surface 4133 and the bent portion 424 come into contact with each other, so as to ensure the continuity of unlocking.

[0514] Figure 97 illustrates an unlocking component in its initial unlocking state (Figure 1), according to some embodiments; Figure 98 illustrates an unlocking component in its initial unlocking state (Figure 2), according to some embodiments. As shown in Figures 97 and 98, before the unlocking handle 410 is pulled, the first arm 422 is positioned within the notch 412 to maintain the stability of the unlocking mechanism 420. Before the unlocking handle 410 is pulled, the groove 413 and the bent portion 424 must not contact each other, as this would create a certain amount of unlocking travel for the electrical port module 300, disrupting the locked state of the electrical port module 300.

[0515] FIG99 illustrates an intermediate unlocking state of an unlocking component according to some embodiments; FIG100 illustrates an intermediate unlocking state of an unlocking component according to some embodiments. As shown in FIG99 and FIG100 , as the unlocking handle 410 rotates, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424. The curved surface 4133 squeezes the bent portion 424, thereby pushing the bent portion 424 toward the second rounded corner 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second rounded corner 4132, and the two also move tangentially. With their tangent point as the fulcrum, the bent portion 424 moves toward the second accommodating cavity 4131. The second accommodating cavity 4131 squeezes the bent portion 424, causing the bent portion 424 to push the unlocking device 420 toward the engaging component 318 and the spring 1061.

[0516] Figure 101 shows the first final unlocking state of an unlocking component according to some embodiments; Figure 102 shows the second final unlocking state of an unlocking component according to some embodiments; and Figure 103 shows the third final unlocking state of an unlocking component according to some embodiments. As shown in Figures 101-103, when unlocking is complete, the bent portion 424 is within the groove 413, and the first arm 422 has broken contact with the notch 412 and is no longer connected.

[0517] The electrical port module provided by the present disclosure includes an upper shell and an unlocking component. The surface of the upper shell has a locking component, which is connected to the elastic sheet of the upper computer through the locking component, thereby locking the electrical port module into the upper computer. The unlocking component includes an unlocking handle and an unlocker, wherein the unlocking handle is provided at the end of the upper shell and is rotatably connected to the upper shell. One end of the unlocking handle is formed with a notch and the other end is formed with a groove. Both the notch and the groove rotate with the rotation of the unlocking handle. The unlocker is slidably connected to the upper shell, and the unlocker includes a main body structure. The main body structure extends toward the end surface of the unlocking handle to form a first arm and a second arm. The first arm is provided in the notch, and the second arm includes an extension arm and a bent portion formed by bending the end of the extension arm. As the notch rotates, the notch applies pressure to the first arm, causing the first arm to slide along the inner wall of the notch until it slips out of the notch, and then continues to abut against the side wall connected to the notch, causing the first arm to move toward the locking component. When the electrical port module is locked, the first arm is positioned within the notch. To prevent the unlocker from acting on the spring clip and the engaging member, the first arm is relatively short, keeping the unlocker as far away from the spring clip and the engaging member as possible, thereby maintaining the locked state. When the first arm is relatively short, the first arm and the notch will become disconnected due to misalignment during movement, until the first arm and the abutting sidewall also become disconnected due to misalignment. As a result, the first arm is no longer compressed and no longer experiences an unlocking stroke. Therefore, as the first arm moves, the bent portion of the second arm enters the groove. During the groove's rotation, the inner wall of the groove compresses the bent portion, causing the second arm to move toward the engaging member, continuing the unlocking stroke until the spring clip is lifted, disengaging the engaging member from the spring clip and releasing the engaging connection between the electrical port module and the host computer. In the present disclosure, the first and second arms are independently stressed, providing a continuous and sufficient unlocking stroke to completely separate the electrical port module from the host computer and unlock the electrical port module. It can be understood that the optical module is a type of electrical port module, and the unlocking component provided in the present disclosure is also applicable to the optical module, that is, the optical module can also adopt the unlocking component provided in the present disclosure.
