[0032] The embodiments of this disclosure will now be described clearly and in detail with reference to the accompanying drawings. However, the described embodiments are merely some, and not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0033] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open and inclusive, meaning "including, but not limited to"; the terms "first" and "second" should not be construed as indicating or implying relative importance or indicating an upper limit on the number; the term "multiple" means two or more; the term "connection" should be interpreted broadly, for example, "connection" can be a fixed connection, a detachable connection, or an integral part, and can be a direct connection or an indirect connection through an intermediate medium; the use of the terms "applicable to" or "configured to" implies open and inclusive language, which does not exclude applicability to or configuration to devices performing additional tasks or steps; descriptions such as "parallel," "perpendicular," "identical," "consistent," and "aligned" are not limited to absolute mathematical theoretical relationships, but also include acceptable error ranges arising in practice, and differences based on the same design concept but due to manufacturing reasons.

[0034] In optical communication technology, to establish information transmission between information processing devices, information is loaded onto light, and the speed of light propagation is used to transmit the information. This light carrying information is called an optical signal. When optical signals are transmitted in optical information transmission equipment, optical power loss can be reduced, enabling long-distance transmission of optical signals. At the same time, the cost of optical information transmission equipment such as optical fibers is lower than that of electrical information transmission equipment such as copper wires. Therefore, optical communication technology can achieve high-speed, long-distance, and low-cost information transmission.

[0035] Information processing equipment typically includes optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., while optical information transmission equipment typically includes optical fibers and optical waveguides. Information processing equipment can only recognize and process electrical signals, while optical communication technology uses optical signals for transmission, requiring optical modules to convert between optical and electrical signals.

[0036] An optical module enables the conversion between optical signals and electrical signals between information processing equipment and optical information transmission equipment. In some embodiments, at least one of the optical signal input or output terminals of the optical module is connected to an optical fiber, and at least one of the electrical signal input or output terminals 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.

[0037] Since multiple information processing devices can transmit information via electrical signals, at least one of these 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 also referred to as the host computer of the optical module. Furthermore, the optical signal input or output terminal of the optical module is called the optical port, and the electrical signal input or output terminal is called the electrical port.

[0038] Figure 1 is a partial structural diagram of an optical communication system according to some embodiments. 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 for optical modules, an optical module 200, an optical fiber 101, and a network cable 103. Among them, the optical fiber 101 is an optical information transmission device, and the network cable 103 is an electrical information transmission device.

[0039] In some embodiments, one end of the optical fiber 101 extends toward the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can undergo total internal reflection in the optical fiber 101, and the propagation of the optical signal in the direction of total internal reflection can almost maintain the original optical power. The optical signal undergoes multiple total internal reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance information transmission based on low power loss.

[0040] The optical communication system includes one or more optical fibers 101. In some embodiments, the optical fiber 101 is detachably connected to the optical module 200. In some embodiments, the optical fiber 101 is non-detachably connected to the optical module 200.

[0041] The host computer 100 is configured to provide data signals to the optical module 200, or receive data signals from the optical module 200, or monitor or control the working status of the optical module 200.

[0042] The host computer 100 includes a housing for accommodating the optical module 200, and an optical module interface 102 disposed on the housing. The optical module 200 is inserted into the housing through the optical module interface 102 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0043] The host computer 100 also includes an external power interface that can connect to an electrical signal network. In some embodiments, the external power interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to connect a network cable 103 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the network cable 103.

[0044] One end of the network cable 103 is connected to the local information processing device 2000, and the other end is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. In some embodiments, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 through 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 transmitted in the optical fiber 101 to the remote information processing device 1000.

[0045] In some embodiments, a first optical signal from a remote information processing device 1000 is transmitted through an optical fiber 101, and the first optical signal from the optical fiber 101 is transmitted to an optical module 200. The optical module 200 converts the first optical signal into a first electrical signal, and transmits the first electrical signal to a 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 a local information processing device 2000.

[0046] In some embodiments, the optical module is a tool for converting optical signals to electrical signals. During the conversion process, the information does not change, but the encoding or decoding method of the information changes.

[0047] In addition to optical network terminals, the host computer 100 also includes optical line terminals (OLTs), optical network equipment (ONTs), or data center servers.

[0048] Figure 2 is a partial structural diagram of a host computer according to some embodiments. To clearly show the connection relationship 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, in some embodiments, the host computer 100 further includes a PCB circuit board 105 disposed in a receiving cavity, and a cage 106 disposed on the surface of the PCB circuit board 105; the optical module 200 is inserted into the cage 106 and fixed by the cage 106.

[0049] In some embodiments, a heat sink 107 is provided on the cage 106 to dissipate heat for the optical module; in some embodiments, the heat sink 107 has protruding structures such as fins to increase the heat dissipation area.

[0050] In some embodiments, an electrical connector is provided inside the cage 106, which is configured to connect to the electrical port of the optical module 200.

[0051] In some embodiments, the optical module 200 is inserted into the cage 106 of the host computer 100, and the cage 106 fixes the optical module 200. The heat generated by the optical module 200 is conducted to the cage 106 and then diffused through the heat sink 107.

[0052] In some embodiments, the optical module 200 is inserted into the cage 106 of the host computer 100, and the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, thereby establishing an electrical signal connection between the optical module 200 and the host computer 100.

[0053] In some embodiments, the optical port of the optical module 200 is connected to the optical fiber 101, thereby enabling the optical module 200 to establish an optical signal connection with the optical fiber 101.

[0054] Figure 3 is a structural diagram of an optical module according to some embodiments, and Figure 4 is an exploded view of an optical module according to some embodiments. As shown in Figures 3 and 4, in some embodiments, the optical module 200 includes a shell, which includes an upper shell 201 and a lower shell 202; wherein, the upper shell 201 and the lower shell 202 are relative concepts. The upper shell 201 covers the lower shell 202, forming two openings 203 and 204, one of which is an electrical port, and the other is an optical port. In some embodiments, the shell forms an opening that serves as both an electrical port and an optical port.

[0055] In some embodiments, the upper housing 201 and the lower housing 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0056] The assembly method, which combines the upper housing 201 and the lower housing 202, facilitates the installation of the circuit board 300, the light emitting component 400, the light receiving component 500, and other components into the aforementioned housing. The upper housing 201 and the lower housing 202 can encapsulate and protect the aforementioned devices.

[0057] The direction of the line connecting the two openings 203 and 204 can be consistent with or inconsistent with the length direction of the optical module 200. For example, opening 203 is located at the end of the optical module 200 (right end in Figure 3), and opening 204 is also located at the end of the optical module 200 (left end in Figure 3). Alternatively, opening 203 is located at the end of the optical module 200, and opening 204 is located on the side of the optical module 200.

[0058] In some embodiments, the lower housing 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and disposed perpendicular to the base plate 2021. The upper housing 201 includes a cover plate 2011, which covers the two lower side plates 2022 of the lower housing 202 to form the aforementioned housing.

[0059] In some embodiments, the upper housing 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and arranged perpendicularly to the cover plate 2011. The two upper side plates are combined with two lower side plates 2022 to realize that the upper housing 201 covers the lower housing 202.

[0060] As shown in Figures 3 and 4, in some embodiments, the optical module includes a circuit board 300 disposed within a housing. The circuit board 300 includes circuit traces, electronic components, and chips. The electronic components and chips are connected according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission, and grounding. Electronic components may include capacitors, resistors, transistors, and metal-oxide-semiconductor field-effect transistors (MOSFETs). Chips may include microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers (LAs), clock and data recovery chips (CDRs), power management chips, and digital signal processing (DSP) chips.

[0061] In some embodiments, the circuit board includes a rigid circuit board. Due to its relatively rigid material, the rigid circuit board can also provide load-bearing support, such as stably supporting the aforementioned electronic components and chips. The rigid circuit board can also be inserted into an electrical connector within the cage 106 of the host computer 100.

[0062] In some embodiments, the circuit board further includes a flexible circuit board. The flexible circuit board can be used independently or in conjunction with a rigid circuit board.

[0063] In some embodiments, the circuit board further includes gold fingers formed on its end surfaces. The gold fingers consist of a plurality of independent pins.

[0064] In some implementations, the gold fingers 301 are disposed on one side of the surface of the circuit board 300 (e.g., the upper surface shown in Figure 4). In some implementations, the gold fingers 301 are disposed on the upper and lower surfaces of the circuit board 300 to provide a greater number of pins, thereby adapting to applications with high pin count requirements.

[0065] In some implementations, the gold fingers of the circuit board extend from the electrical port. The gold fingers are inserted into the electrical connector of the host computer 100. The circuit board is inserted into the cage 106, and the gold fingers 301 are connected to the electrical connector inside the cage 106. The gold fingers 301 are configured to establish an electrical connection with the host computer, enabling electrical connection functions such as power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, and data signal transmission.

[0066] In some embodiments, the light emitting component 400 and the light receiving component 500 may be physically separated from the circuit board 300, and the light emitting component 400 and the light receiving component 500 may be electrically connected to the circuit board 300 through corresponding flexible circuit boards or electrical connectors.

[0067] In some embodiments, at least one of the light emitting component 400 or the light receiving component 500 is located on the side of the circuit board 300 away from the gold finger 301.

[0068] In some embodiments, at least one of the light emitting component 400 or the light receiving component 500 may be directly disposed on the circuit board 300. For example, at least one of the light emitting component 400 or the light receiving component 500 may be disposed on the surface of the circuit board 300 or the side of the circuit board 300.

[0069] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to establish a fixed connection between the optical module 200 and the host computer 100, or to release the fixed connection between the optical module 200 and the host computer 100, thereby allowing the optical module 200 to be pulled out of the cage 106. Exemplarily, the unlocking component 600 is located outside the lower housing 202, and the unlocking component 600 includes a locking element that matches the cage 106 of the host computer 100.

[0070] Figure 5A is an exploded view of an unlocking component and a lower housing according to some embodiments, and Figure 5B is an exploded view of an unlocking component according to some embodiments. As shown in Figures 5A and 5B, in some embodiments, the unlocking component 600 may include a locking member 630 for locking the connecting cage 106. The locking member 630 may be located on the outside of the base plate 2021, and the locking member 630 is assembled to the base plate 2021. Exemplarily, the locking member 630 includes a locking body 631, on which an engaging portion 632 is formed for locking the connecting cage 106.

[0071] The locking member 630 is located on the outer side of the base plate 2021, making the unlocking member 600 relatively independent. The unlocking member 600 can be assembled onto the lower housing 202 after the upper housing 201 and lower housing 202 are assembled and connected. This makes the assembly of the unlocking member 600 relatively independent of the assembly of other structures of the optical module 200, facilitating the assembly of the optical module. In some embodiments, the locking member 630 can be assembled and connected to the upper housing 201.

[0072] In some embodiments, the unlocking component 600 may include a drive component 610. The drive component 610 is fitted to one end of the locking component 630 so that the drive component 610 can drive the locking component 630 to unlock the engaging portion 632 and the cage 106.

[0073] In some embodiments, the drive member 610 can be assembled and connected to the lower housing 202, and the drive member 610 can rotate around the assembly point between the drive member 610 and the lower housing 202. The drive member 610 is assembled and connected to the locking member 630. The rotating drive member 610 can drive the locking member 630 to move, causing one end of the locking member 630 to tilt upward and the other end to sink, thereby unlocking the engaging part 632 from the cage 106, allowing the optical module 200 to disengage from the cage 106. Exemplarily, the drive member 610 has a ring-shaped structure and is sleeved on the end of the lower housing 202. In some embodiments, the drive member 610 can be assembled and connected to the upper housing 201.

[0074] In some embodiments, the unlocking component 600 may include an upper cover 620. The upper cover 620 may be fitted to the lower housing 202, or it may be fitted to the upper housing 201. The upper cover 620 may form a receiving space with the outer side of the base plate 2021. The locking component 630 is fitted into this receiving space, and the upper cover 620 covers the locking component 630, so that the upper cover 620 can both assist in fixing the locking component 630 and protect it. The upper cover 620 has a locking through hole 621, and a locking part 632 is fitted into the locking through hole 621. The locking part 632 can enter and exit the locking through hole 621. Of course, in some embodiments, the upper cover 620 may also have a notch or similar feature for the locking part 632 to enter and exit.

[0075] In some embodiments, the unlocking component 600 may include an elastic element 640, which elastically supports the other end of the locking component 630. When it is necessary to unlock the optical module 200, an external force is applied to the driving component 610, causing the driving component 610 to rotate and move away from its initial position. The driving component 610 then moves the locking component 630, compressing the elastic element 640. Reducing or removing the external force causes the elastic element 640 to elastically recover, returning the locking component 630 to its initial position. The driving component 610 then rotates in the opposite direction, returning to its initial position. Exemplarily, the elastic element 640 may be a spring, with one end connected to the lower housing 202 and the other end connected to the locking component 630.

[0076] In some embodiments, the unlocking component 600 may include a fastener 650, which is fixedly connected to the upper cover 620 and the lower housing 202. For example, the fastener 650 may be a bolt, screw, etc.

[0077] Figure 5C is a partial schematic diagram of a lower housing according to some embodiments. As shown in Figure 5C, in some embodiments, a first mounting surface 2021a may be formed on the outer side of the base plate 2021. The first mounting surface 2021a can be fitted with a support unlocking component 600. Exemplarily, the first mounting surface 2021a is used to support the upper cover 620.

[0078] In some embodiments, a second mounting surface 2021b may be formed on the outer side of the base plate 2021. The second mounting surface 2021b is lower than the first mounting surface 2021a, creating a height difference between the two surfaces. The second mounting surface 2021b can be used to mount and connect the drive member 610 or the locking member 630, etc. The lower profile of the second mounting surface 2021b provides space for the locking member 630 to move.

[0079] In some embodiments, a mounting post 205 may be formed on the base plate 2021. The mounting post 205 is used to mount and connect the top cover 620. The top cover 620 is connected to the mounting post 205 via a fastener 650. Exemplarily, the bottom of the mounting post 205 may be connected to a second mounting surface 2021b, and a through hole is formed on the mounting post 205. The top cover 620 can be connected to the through hole via the fastener 650.

[0080] In some embodiments, the mounting post 205 may be embedded with a connecting locking member 630 to limit the locking member 630 by the mounting post 205.

[0081] The locking member 630 can be connected to the base plate 2021 via a shaft and slot connection, allowing the locking member 630 to rotate around a rotation axis connected to the base plate 2021. For example, the base plate 2021 may have an assembly shaft, and the locking member 630 may have an assembly slot. The assembly shaft of the base plate 2021 and the assembly slot of the locking member 630 may be assembled and connected, allowing the locking member 630 to rotate around the assembly shaft.

[0082] In some embodiments, a first support base 206 may be formed on the base plate 2021, which can support the connecting locking member 630. Exemplarily, a first mounting groove 2061 is formed on the side of the first support base 206, which is used to mount the connecting locking member 630, so that the locking member 630 is rotatably connected to the lower housing 202 through the first mounting groove 2061. The bottom of the first support base 206 can be connected to a second mounting surface 2021b. The opening of the first mounting groove 2061 can face the electrical port end of the optical module 200, facilitating the mounting of the connecting locking member 630 on the first support base 206.

[0083] In some embodiments, a second support 207 may be formed on the base plate 2021, which can support the connecting locking member 630. Exemplarily, a second mounting groove 2071 is formed on the side of the second support 207, which is used to mount the connecting locking member 630, so that the locking member 630 is rotatably connected to the lower housing 202 through the second mounting groove 2071. The bottom of the second support 207 can be connected to a second mounting surface 2021b. The opening of the second mounting groove 2071 can face the electrical port end of the optical module 200, facilitating the mounting of the connecting locking member 630 on the second support 207.

[0084] In some embodiments, the first support 206 may be located on one side of the assembly column 205, and the second support 207 may be located on the other side of the assembly column 205.

[0085] In some embodiments, an unlocking through hole 2023 may be provided on the base plate 2021. The unlocking through hole 2023 penetrates the base plate 2021 and connects to the inner cavity of the lower housing 202. The unlocking through hole 2023 is located below the engaging portion 632. When the optical module 200 is unlocked, one end of the locking member 630 that provides the engaging portion 632 sinks into the unlocking through hole 2023, causing the engaging portion 632 to disengage from the cage 106, thereby unlocking the optical module 200 from the cage 106. Exemplarily, the unlocking through hole 2023 may penetrate the second mounting surface 2021b, and the unlocking through hole 2023 is located on the side of the mounting post 205.

[0086] In some embodiments, a partition 210 is formed within the lower housing 202. A notch is formed on the partition 210, and an unlocking through hole 2023 covers the notch on the partition 210. An elastic member 640 is located within the notch and is connected to the partition 210.

[0087] In some embodiments, a first connecting portion 208 may be formed on the base plate 2021, and the first connecting portion 208 is fitted with a connecting drive member 610. The drive member 610 can rotate about the first connecting portion 208. Exemplarily, the first connecting portion 208 is located at the edge of one side of the second mounting surface 2021b.

[0088] In some embodiments, a first connecting groove 2081 is formed on the first connecting portion 208, and the orientation of the first connecting groove 2081 is opposite to that of the base plate 2021. The first connecting groove 2081 is fitted with a connecting drive member 610.

[0089] In some embodiments, a second connecting portion 209 may be formed on the base plate 2021, and the second connecting portion 209 is fitted with a connecting drive member 610. The drive member 610 can rotate about the second connecting portion 209. Exemplarily, the second connecting portion 209 is located at the edge on the other side of the second mounting surface 2021b.

[0090] In some embodiments, a second connecting groove 2091 is formed on the second connecting portion 209, and the orientation of the second connecting groove 2091 is opposite to that of the base plate 2021. The second connecting groove 2091 is fitted with a connecting drive member 610.

[0096] Figure 6A is a structural diagram of a driving member according to some embodiments, and Figure 6B is a structural diagram of a driving member according to some embodiments. As shown in Figures 6A and 6B, in some embodiments, the driving member 610 may include a driving rod 611. The driving rod 611 can drive the connecting locking member 630. A driving portion 6111 is formed on the driving rod 611. The driving portion 6111 can be a structure protruding from the surface of the driving rod 611, and the driving portion 6111 can drive the connecting locking member 630. When unlocking the optical module 200, force is applied to the driving member 610, causing the driving rod 611 to rotate. The assembly relationship between the driving portion 6111 and one end of the locking member 630 changes, causing the driving portion 6111 to lift one end of the locking member 630. Exemplarily, the driving portion 6111 can be a protruding structure provided on the side of the driving rod 611, such as a protrusion with an elliptical or circular cross-section, which facilitates uniform resistance during the contact between the driving portion 6111 and the locking member 630, thereby making the driving member 610 rotate smoothly.

[0097] In some embodiments, one end of the drive rod 611 is fitted to the first connecting part 208, and the other end of the drive rod 611 is fitted to the second connecting part 209. The drive rod 611 can rotate relative to the second connecting part 209 of the first connecting part 208.

[0119] Figure 9A is an assembly diagram of an unlocking component according to some embodiments; Figure 9B is an assembly diagram of an unlocking component according to some embodiments; Figure 9C is an assembly cross-sectional view of an unlocking component according to some embodiments; Figure 9D is an assembly diagram of an unlocking component according to some embodiments; and Figure 9E is an assembly cross-sectional view of an unlocking component according to some embodiments. Figures 9A-9E illustrate the assembly process of an unlocking component.

[0120] As shown in Figure 9A, in some embodiments, the drive member 610 is sleeved on the lower housing 202. The drive rod 611 is assembled and connected to the first connecting portion 208 and the second connecting portion 209, so that the drive rod 611 is engaged within the first connecting groove 2081 and the second connecting groove 2091. The bridging portion 612, the first assembly portion 613, and the second assembly portion 614 are assembled and connected to the outer surface of the lower housing 202. The partition 210 is fixedly connected to the elastic member 640. The drive member 6111 is close to the baffle 2025.

[0121] As shown in Figures 9B and 9C, in some embodiments, the locking member 630 is sleeved on the mounting post 205, the first connecting post 634 is engaged in the first mounting groove 2061, and the second connecting post 635 is engaged in the second mounting groove 2071. The lifting part 638 covers the drive rod 611, and the other end of the locking body 631 is suspended above the unlocking through hole 2023, so that the engaging part 632 is located above the unlocking through hole 2023. The positioning post 639 connects to the elastic member 640. Exemplarily, the side of the drive rod 611 contacts the lifting part 638, while the drive part 6111 does not contact the lifting part 638.

[0122] As shown in Figures 9D and 9E, in some embodiments, the upper cover 620 covers the locking member 630, and the unlocking through hole 2023 is fitted onto the engaging part 632. The first limiting plate 2026 is assembled to the first limiting part 627, and the second limiting plate 2027 is assembled to the second limiting part 628. The fixing member 650 is fixedly connected to the upper cover 620 and the mounting post 205.

[0123] Figure 10A is an assembly diagram of an optical module and a cage according to some embodiments, Figure 10B is a cross-sectional view of an unlocking component in use according to some embodiments, and Figure 10C is a cross-sectional view of an unlocking component in use according to some embodiments. As shown in Figures 10A and 10B, a locking spring 1061 is formed on the cage 106. During the process of inserting the optical module 200 into the cage 106, when the engaging part 632 initially contacts the locking spring 1061, the engaging part 632 is squeezed by the locking spring 1061, and the other end of the locking member 630 sinks down; until the engaging part 632 contacts the mounting hole on the locking spring 1061, the other end of the locking member 630 is lifted by the elastic member 640. When the optical module 200 is inserted into the cage 106, the inner side of the locking spring 1061 abuts against the top surface of the second upper cover 624 and the locking spring 1061 is engaged with the engaging part 632, thereby fixing the optical module in the cage by the locking spring 1061 and the engaging part 632.

[0124] The rotating drive component 610 and drive rod 611 rotate around the first connecting part 208 and the second connecting part 209. The drive part 6111 moves away from the baffle 2025 to gradually contact the lifting part 638 and lift one end of the locking body 631. Since the first support 206 binds the first connecting post 634 and the second support 207 binds the second connecting post 635, as the lifting part 638 is lifted and the locking body 631 rotates, the engaging part 632 sinks down along with the other end of the locking body 631. When the drive component 610 rotates to a preset position, the top of the engaging part 632 is lower than the top surface of the second upper cover 624, changing the connection state between the locking spring 1061 and the engaging part 632, thereby releasing the optical module 200 from the host computer. Pulling the drive component 610, the optical module 200 can be pulled out of the cage 106.

[0125] The other end of the locking body 631 sinks down to compress the elastic member 640. When the force used to rotate the drive member 610 decreases or is removed, or when the drive member 610 is rotated in the opposite direction, the elastic member 640 returns to lift the other end of the locking body 631, so that the engaging part 632 returns to its initial position and the lifted part 638 sinks down to return to its initial position.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this disclosure.
