[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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. As shown in Figures 3 and 4, the optical module 200 includes a housing, a circuit board 300 disposed within the housing, and an optical transceiver component 400.

[0091] The housing includes an upper housing 201 and a lower housing 202 . The upper housing 201 covers the lower housing 202 to form the housing having two openings 203 and 204 . The outer contour of the housing is generally a square.

[0092] In some embodiments, the lower shell 202 includes a base plate 2021 and two lower side plates 2022 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, and the cover plate 2011 covers the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0093] In some embodiments, the lower shell 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and arranged perpendicularly to the base plate 2021; the upper shell 201 includes a cover plate 2011 and two upper side plates 2012 located on both sides of the cover plate 2011 and arranged perpendicularly to the cover plate 2011. The two upper side plates 2012 are combined with the two lower side plates 2022 to achieve the upper shell 201 covering the lower shell 202.

[0094] The direction of the line connecting the two openings 203 and 204 can be consistent with the length of the optical module 200, or it can be inconsistent with the length of the optical module 200. For example, opening 203 is located at the end of the optical module 200 (the left end in Figure 3), and opening 204 is also located at the end of the optical module 200 (the right 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.

[0095] The combined assembly of the upper housing 201 and the lower housing 202 facilitates the installation of components such as the circuit board 300 and the optical transceiver 400 into 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 and the optical transceiver 400, the positioning, heat dissipation, and electromagnetic shielding components of these components are easily arranged, facilitating automated production.

[0096] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0097] 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.

[0098] For example, the unlocking component 600 is located on the outside of the two lower side panels 2022 of the lower housing 202 and includes a snap-fit ​​component that mates with the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the snap-fit ​​component of the unlocking component 600 secures the optical module 200 in the cage 106. When the unlocking component 600 is pulled, the snap-fit ​​component of the unlocking component 600 moves accordingly, thereby changing the connection between the snap-fit ​​component and the host computer, thereby releasing the optical module 200 from the cage 106 and allowing the optical module 200 to be removed from the cage 106.

[0099] 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.

[0100] 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. For example, the rigid circuit board can stably carry the above-mentioned electronic components and chips; the rigid circuit board can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0101] The circuit board 300 also includes a gold finger formed on the surface of its end, and the gold finger is composed of a plurality of independent pins. The circuit board 300 is inserted into the cage 106, and the gold finger is connected to the electrical connector in the cage 106. 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.

[0102] A fiber optic receptacle 205 is provided at the optical port of the optical module 200, and a second optical fiber 206 is disposed within the optical module 200. A fiber optic adapter 207 is provided at one end of the second optical fiber 206, which is embedded within the fiber optic receptacle 205. The other end of the second optical fiber 206 is connected to the optical transceiver component 400. Exemplarily, the second optical fiber 206 is a fiber optic ribbon comprising multiple optical fibers for transmitting multiple optical signals. A fiber optic connector is provided on the external optical fiber, and a fiber optic plug is inserted into the fiber optic receptacle 205, coupling the external optical fiber to the second optical fiber 206. The fiber optic plug is removable and pluggable into the fiber optic receptacle 205.

[0103] In order to adapt to some optical module usage scenarios, some optical modules are provided with pigtails. Taking into account the cost and the requirements for the firmness of the connection between the pigtail and the optical module, the pigtail is usually fixed directly on the optical module. In some embodiments, the pigtail and the second optical fiber 206 are continuous whole optical fibers, and an optical fiber connecting component is provided at the optical port of the optical module to connect the pigtail to the optical port of the optical module through the optical fiber connecting component. Figure 5 is a schematic diagram of the local structure of an optical module with a pigtail provided according to some embodiments of the present disclosure. As shown in Figure 5, a protective cover 02 is provided on the pigtail 01, and the protective cover 02 is embedded in the optical port of the optical module so that the upper shell 03 and the lower shell 04 of the optical module wrap and fix the protective cover 02. Exemplarily, the protective cover 02 is a cylindrical structure, and a through hole formed by the upper shell 03 and the lower shell 04 is provided at the optical port of the optical module, and the protective cover is embedded in the through hole.

[0104] Figure 6 is a schematic diagram of the structure of an upper housing according to some embodiments of the present disclosure, and Figure 7 is a schematic diagram of the structure of a lower housing according to some embodiments of the present disclosure. Figures 6 and 7 illustrate a housing structure in which a fiber optic receptacle is mounted at the optical port of an optical module. As shown in Figures 6 and 7, near the optical port of the optical module, a first fiber optic receptacle mounting portion 2013 is provided on the upper housing 201, and a second fiber optic receptacle mounting portion 2023 is provided on the lower housing 202. When the upper housing 201 and the lower housing 202 are joined, the first and second fiber optic receptacle mounting portions 2013 and 2023 together form a fiber optic receptacle mounting cavity for mounting and securing a fiber optic receptacle 205. Exemplarily, the first fiber optic receptacle mounting portion 2013 is a recess formed at one end of the upper housing 201, and the second fiber optic receptacle mounting portion 2023 is a recess formed at one end of the lower housing 202. The sidewalls of the first and second fiber optic receptacle mounting portions 2013 and 2023 are used to mount and connect the fiber optic receptacle 205.

[0105] In some embodiments, the first fiber optic receptacle mounting portion 2013 is provided with a first limiting protrusion 131, and the second fiber optic receptacle mounting portion 2023 is provided with a second limiting protrusion 231. The first limiting protrusion 131 and the second limiting protrusion 231 are used to limit the connection to the fiber optic receptacle 205. The first limiting protrusion 131 includes a first limiting portion 1311 and a second limiting portion 1312. The first limiting portion 1311 is disposed on the upper side panel on one side of the cover plate 2011, and the second limiting portion 1312 is disposed on the upper side panel on the other side of the cover plate 2011. The second limiting protrusion 231 includes a third limiting portion 2311, a fourth limiting portion 2312, and a fifth limiting portion 2313. The third limiting portion 2311 is disposed on the lower side panel on one side of the base plate 2021, the fourth limiting portion 2312 is disposed on the base plate, and the fifth limiting portion 2313 is disposed on the lower side panel on the other side of the base plate 2021. Exemplarily, one end of the fourth limiting portion 2312 is connected to the third limiting portion 2311, and the other end of the fourth limiting portion 2312 is connected to the fifth limiting portion 2313; the second limiting protrusion 231 extends from the lower side plate on the right side of the lower shell 202 through the bottom plate to the lower side plate on the left side.

[0106] The shape of the optical fiber receptacle 205 differs significantly from the shape of the protective sleeve on the pigtail. The upper housing 201 and lower housing 202 designed for the optical fiber receptacle 205 are not compatible with the protective sleeve on the pigtail. Therefore, to achieve the optical module with pigtails shown in Figures 3 and 4, the housing structure of the optical module needs to be adjusted. For example, the upper and lower housing molds need to be newly created to match the protective sleeve on the pigtail. However, creating these molds is relatively time-consuming and costly, making them unsuitable for use in optical module manufacturing.

In some embodiments, first optical fiber 710 and second optical fiber 206 are integral optical fibers.

[0109] The snap-fitting component 500 is mounted on the first optical fiber connection component 720. The snap-fitting component 500 cooperates with the optical fiber receptacle mounting cavity to assemble and secure the pigtail assembly 700 with the upper housing 201 and the lower housing 202, thereby attaching a pigtail to the optical module. Therefore, in the optical module provided by the disclosed embodiment, the snap-fitting component 500 secures the first optical fiber 710 to the optical fiber receptacle mounting cavity, thereby enabling the optical module to be attached with a pigtail without modifying the upper housing 201 and the lower housing 202 of the optical module, based on the structural components of the original optical module without a pigtail. This also improves the versatility of the upper housing 201 and the lower housing 202, reduces the number of molds for the upper housing 201 and the lower housing 202, and reduces the development cost of the optical module.

[0159] The fiber protection portion 650 can be connected to the avoidance hole 633 with an interference fit, so that the fiber protection portion 650 fills the avoidance hole 633, reducing the gap between the avoidance hole 633 and the fiber protection portion 650, and effectively preventing dust from entering the optical module through the gap between the avoidance hole 633 and the fiber protection portion 650. To facilitate installation and fixation, the hardness of the fiber protection portion 650 can be less than that of the fixing member 630.

[0160] The fixing member 630 may be provided with a first through hole 632 .

[0161] The fixing member 630 may be provided with a second through hole 631, and the first through hole 632 is connected to the second through hole 631. The diameter of the first through hole 632 may be larger than the diameter of the second through hole 631. The pin 640 may pass through the second through hole 631.

[0162] The fixing member 630 can be disposed between the side wall of the optical fiber plug 620 and the inner wall of the claw.

[0163] In some embodiments, to facilitate the removal of the ferrule 640, the diameter of the exposed portion 641 may be larger than the diameter of the first through hole 632. Thus, when the ferrule 640 is inserted into the pinhole 6222 of the optical fiber plug 620 through the first through hole 632, the exposed portion 641 is exposed outside the fixing member 630, allowing the ferrule 640 to move left and right within the pinhole 6222 and the first through hole 632. The fixing member 630 is then moved to engage the connecting portion 642 with the second through hole 631. At this point, the ferrule 640 cannot move left and right within the second through hole 631, thereby securing the ferrule 640 to the fixing member 630.

[0164] In some embodiments, the fiber optic plug 620 may be an MT male connector, and the plug of the external fiber optic plug 700 may be a corresponding MT female connector. That is, after the pin 640 is fixed to the fiber optic plug 620, the end of the pin 640 facing away from the exposed portion 641 protrudes from the fiber optic plug 620. In this way, when the external fiber optic plug 700 is inserted into the claw 610, the protruding pin 640 is inserted into the socket on the end face of the external fiber optic plug 700 to achieve the positioning connection between the fiber optic plug 620 and the external fiber optic plug 700.

When an external optical fiber enters the light passage 6130 from the side having the second elastic clip 6161, the second elastic clip 6161 pushes outward. Once the external optical fiber reaches a predetermined position, the second elastic clip 6161 clamps inward.

[0204] The first elastic buckle 6160 and the second elastic buckle 6161 can be arranged opposite to each other, so that the external optical fiber is subjected to balanced force when passing through the first elastic buckle 6160 and the second elastic buckle 6161, thereby avoiding low coupling efficiency caused by uneven force on the external optical fiber.

The transition portion 6641 gradually tilts upward from the fixing member 6111 toward the support member 6112 (from left to right). During installation, the lower surface of the fiber optic plug 620 can be inserted at an angle along the transition portion 664. The left end of the transition portion 664 (the end adjacent to the fixing member 6111) is lower than the right end of the transition portion 664.

[0234] Figure 41 illustrates the installation process of a fiber optic adapter according to some embodiments of the present disclosure. Figure 42 illustrates a second cross-sectional schematic diagram of a fiber optic adapter in an optical module according to some embodiments of the present disclosure. As shown in Figures 41 and 42, during installation, the fiber optic plug 620, the fixing member 630, the ferrule 640, and the fiber protection portion 650 can be connected. The fiber optic plug 620 is inserted from top to bottom through the upper opening of the support member 6112 into the lower housing 611 of the claw. During installation, the ferrule-side surface 6224 of the fixing member 622 contacts the first support side plate 6610 of the lower housing 611. The ferrule-side surface 6225 of the fixing member 622 contacts the second support side plate 6620 of the lower housing 611. The left side of the fixing member 622 abuts the first support step 6612 and the second support step 66120, defining the relative left-right position of the fixing member 622 and the lower housing 611. The tilted position of the first support step 6612 facilitates installation of the fiber optic plug 620. The lower surface of the optical fiber plug 620 can be inserted obliquely along the transition portion 664. The left end of the transition portion 664 (adjacent to the fixing member 6111) is lower than the right end of the transition portion 664.

[0235] In some embodiments, the inner wall of the first supporting side plate may be provided with a third supporting step 6613 , and the left side of the third supporting step 6613 protrudes from the right side of the third supporting step 6613 .

[0236] The fixing member 630 is embedded in the right side of the third support step 6613, and the left side of the fixing member 630 can be against the third support step 6613. The third support step 6613 can limit the fixing member 630 in the left and right directions, which is convenient for installation.

[0237] The third support step 6613 can be arranged at an angle, and the distance between the upper end of the third support step 6613 and the fixing member 6111 can be smaller than the distance between the lower end of the third support step 6613 and the fixing member 6111. That is, the upper end of the third support step 6613 is arranged to the left of the lower end of the third support step 6613.

[0238] In some embodiments, the inclination angle of the third supporting step 6613 may be the same as the inclination angle of the first supporting step 6612 .

[0239] The third supporting step 6613 may be located on the right side of the first supporting step 6612 (in a direction away from the fixing member 6111 ).

[0240] The inner wall of the second supporting side plate may be provided with a fourth supporting step 66130 , and the left side of the fourth supporting step 66130 protrudes from the right side of the fourth supporting step 66130 .

[0241] The fixing member 630 is embedded in the right side of the fourth supporting step 66130, and the left side of the fixing member 630 can be against the fourth supporting step 66130. The fourth supporting step 66130 can limit the fixing member 630 in the left and right directions, which is convenient for installation.

[0242] The fourth support step 66130 can be tilted, and the distance between the upper end of the fourth support step 66130 and the fixing member 6111 can be smaller than the distance between the lower end of the fourth support step 66130 and the fixing member 6111. That is, the upper end of the fourth support step 66130 is arranged to the left of the lower end of the fourth support step 66130.

[0243] In some embodiments, the inclination angle of the fourth supporting step 66130 may be the same as the inclination angle of the second supporting step 66120 .

[0244] The fourth supporting step 66130 is located on the right side of the second supporting step 66120 (in a direction away from the fixing member 6111 ).

[0245] During installation, the fiber optic plug 620, fixing member 630, ferrule 640, and fiber protection member 650 can be connected. The fiber optic plug 620 and fixing member 630 are positioned from top to bottom, entering the claw lower housing 611 through the upper opening of the support member 6112. During installation, the ferrule-side surface 6224 of the fixing member 622 contacts the first support side plate 6610 of the claw lower housing 611. The ferrule-side surface 6225 of the fixing member 622 contacts the second support side plate 6620 of the claw lower housing 611. The left side of the fixing member 622 abuts the first support step 6612 and the second support step 66120, defining the relative position of the fixing member 622 and the claw lower housing 611 in the left-right direction. The inclined arrangement of the first support step 6612 facilitates installation of the fiber optic plug 620. The left side wall of the fixing member 630 can abut the third support step 6613 and the fourth support step 66130. The front and rear side walls of the fixing member 630 abut against the inner walls of the second supporting side plate and the first supporting side plate.

[0246] A side guard 6114 may be provided between the first supporting side plate 6610 and the second supporting side plate 6620. One side of the side guard 6114 may be connected to the fixing member 6111. The sidewall of the fixing member 6111 may extend outward to form the side guard 6114. The side guard 6114 abuts against the shielding groove 6151, increasing the contact area between the upper and lower housings 612 and 611 of the claws, thereby reducing the path for dust or air to enter the light aperture through the gap between the upper and lower housings 612 and 611. The side guard 6114 abuts against the shielding groove 6151, further enhancing the sealing of the optical adapter.

[0247] The side baffle 6114 abuts against the shielding groove 6151, which can increase the contact area between the claw upper shell 612 and the claw lower shell 611, reduce the deformation of the claw upper shell 612 during the installation process after being subjected to force, and increase the sealing of the optical adapter.

[0248] The side baffle 6114 may be disposed between an inner wall of the first supporting side plate 6610 and an inner wall of the second supporting side plate 6620 .

[0249] The lower housing of the claw may include a bottom plate groove 6642. The bottom plate groove 6642 may be located on the supporting base plate 6630. The bottom plate groove 6642 may be used to secure the optical fiber plug 620 and limit the position of the optical fiber plug 620 in the left and right longitudinal direction. The fixing portion 622 may be located within the bottom plate groove 6642 and limit the position of the fixing portion 622 in the left and right longitudinal direction.

[0250] In some embodiments, the left side wall of the bottom plate groove 6642 is positioned in the left-right direction in the same direction as the first support step 6612. As the optical fiber plug 620 is inserted into the claw through the opening of the support member 6112, the ferrule-side surface 6224 of the fixing portion 622 of the optical fiber plug is inserted into the right side of the first support step 6612, and the stepped surface between the ferrule-side surface 6224 of the fixing portion 622 and the ferrule 621 abuts against the first support step 6612, until the bottom surface of the fixing portion 622 is inserted into the bottom plate groove 6642.

[0251] In some embodiments, the fixing member 430 may be located within the bottom plate groove 6642, which may limit the position of the fixing member 430 in the left-right longitudinal direction. The fixing portion 622 and the fixing member 430 may be located within the bottom plate groove 6642, which may limit the position of the fixing portion 622 and the fixing member 430 in the left-right longitudinal direction.

[0252] The arm securing region 661 of the first supporting side plate 6610 may include a first slide groove 6614. The first upper shell guard plate 6123 is secured to the first slide groove 6614 and slides from right to left along the first slide groove 6614, gradually connecting the claw upper shell 612 with the claw lower shell 611 from the right side, ultimately positioning the side baffle 6114 within the shielding groove 6151. The first connecting protrusion 6611 is positioned within the first mounting hole 6141, securing the claw upper shell 612 to the claw lower shell 611.

[0253] The first slide groove 6614 is located on the lower surface of the first support side plate 6610. The first slide groove 6614 can make the lower surface of the first support side plate 6610 higher than the lower surface of the support base plate 6630, so that the lower surface of the first upper shell guard plate 6123 is flush with the lower surface of the support base plate 6630 after installation.

[0254] In some embodiments, the first supporting side plate 6610 may be provided with a first upper shell support portion 6615. The first upper shell support portion 6615 is raised relative to the lower surface of the first supporting side plate 6610, thereby increasing the distance from the upper shell cover 615 of the claw upper shell and tightening the upper shell cover 615 to prevent the upper shell cover 615 from separating from the claw lower shell 611.

[0255] The arm securing region 661 of the second support side plate 6620 may include a second slot. The second upper shell guard plate 61230 is secured to the second slot and slides along the second slot from right to left, gradually connecting the claw upper shell 612 with the claw lower shell 611 from the left side, ultimately positioning the side guard plate 6114 within the shielding groove 6151. The second connecting protrusion 6621 is positioned within the second mounting hole 6142, securing the claw upper shell 612 to the claw lower shell 611.

[0256] The second slide groove is located on the lower surface of the second support side plate. The second slide groove can make the lower surface of the second support side plate 6620 higher than the lower surface of the support base plate 6630, so that the lower surface of the second upper shell guard plate 61230 is flush with the lower surface of the support base plate 6630 after installation.

[0257] In some embodiments, a second upper shell support portion can be provided on the second support side plate 6620. The second upper shell support portion protrudes from the lower surface of the second support side plate 6620, increasing the distance from the upper shell cover 615 of the claw upper shell. This tightens the upper shell cover 615 and prevents separation between the upper shell cover 615 and the claw lower shell 611. The second upper shell support portion is adjacent to the raised area 662 of the support arm.

[0258] In some embodiments, the support base may be provided with a first lower housing baffle 6643. The first lower housing baffle 6643 may protrude relative to the inner wall of the support base. The left side wall of the first lower housing baffle 6643 may abut against the right side wall of the optical fiber plug 620 (when the fixing member 630 is not present).

[0259] In some embodiments, the left side wall of the first lower housing baffle 6643 can abut against the right side wall of the fixing member 630, and the first lower housing baffle 6643 can limit the left and right positions of the optical fiber plug 620 and the fixing member 630. The bottom surface of the fixing portion 622 can be embedded in the bottom plate groove 6642, and the bottom surface of the fixing member 630 can be embedded in the bottom plate groove 6642.

[0260] In some examples, the upper surface of the first lower housing baffle 6643 can be higher than the lower surface of the exposed area 652. The sidewalls of the exposed area 652 can abut against the inner wall of the first lower housing baffle 6643. The first lower housing baffle 6643 can limit the front-to-back movement of the exposed area 652. The upper surface of the first lower housing baffle 6643 can be lower than or equal to the lowest point of the lower surface of the pin 640 to avoid affecting the installation and removal of the pin 640.

[0261] The upper surface of the first lower shell baffle 6643 can be lower than or equal to the height of the lowest point of the lower surface of the exposed portion 641 to avoid affecting the installation and removal of the pin 640.

[0262] The first lower shell baffle 6643 can be connected to the first supporting side plate 6610 to seal the optical port to prevent dust from entering.

[0263] In some embodiments, the support base can be provided with a second lower housing baffle 66430. The second lower housing baffle 66430 can be raised relative to the inner wall of the support base. The left side wall of the second lower housing baffle 66430 can abut against the right side wall of the optical fiber plug 620 (when the fixing member 630 is not present).

[0264] In some embodiments, the left side wall of the second lower housing baffle 66430 can abut against the right side wall of the fixing member 630, and the second lower housing baffle 66430 can limit the left and right positions of the optical fiber plug 620 and the fixing member 630. The bottom surface of the fixing portion 622 can be embedded in the bottom plate groove 6642, and the bottom surface of the fixing member 630 can be embedded in the bottom plate groove 6642.

[0265] In some examples, the upper surface of the second lower housing baffle 66430 can be higher than the lower surface of the exposed area 652. The sidewalls of the exposed area 652 can abut against the inner wall of the second lower housing baffle 66430. The second lower housing baffle 66430 can limit the forward and backward movement of the exposed area 652. The upper surface of the second lower housing baffle 66430 can be lower than or equal to the lowest point of the lower surface of the pin 640 to avoid affecting the installation and removal of the pin 640.

[0266] In some embodiments, the left side wall of the second lower shell baffle 66430 may be provided with a baffle slope 66431 to guide the optical fiber plug 620.

[0267] The upper surface of the second lower shell baffle 66430 can be lower than or equal to the height of the lowest point of the lower surface of the exposed portion 641 to avoid affecting the installation and removal of the pin 640.

[0268] The second lower shell baffle 66430 can be connected to the second supporting side plate 6620 to seal the optical port to prevent dust from entering.

[0269] For ease of description, the rightmost end of the light-through hole formed by the upper and lower jaw shells 612 and 611 is referred to as the right light-through hole. The fixing member 630 abuts against the inner wall of the right light-through hole. The width of the fixing member 630 in the front-to-back direction is greater than the width of the right light-through hole in the front-to-back direction, preventing dust from entering the ferrule through the gap between the right light-through hole and the exposed area 652.

[0270] The width of the fixing member 630 in the vertical direction is greater than the width of the right light hole in the vertical direction, which can prevent dust from entering the ferrule through the vertical gap between the right light hole and the exposed area 652.

[0271] In some embodiments, the width of the fixing portion 622 in the front-to-back direction is greater than the width of the right light hole in the front-to-back direction, which can prevent dust from entering the ferrule through the gap in the front-to-back direction between the right light hole and the exposed area 652.

[0272] The width of the fixing portion 622 in the vertical direction is greater than the width of the right light hole in the vertical direction, which can prevent dust from entering the ferrule through the vertical gap between the right light hole and the exposed area 652.

[0273] In some embodiments of the present disclosure, one end of the optical fiber protection portion 650 may first be inserted into the fixing portion 622 through the protection hole 6221 .

[0274] The pin 640 can be connected to the fixing member 630, with the connecting portion 642 snapped into the second through hole 631, and the exposed portion 641 exposed on the outside of the fixing member 630. The insertion portion 643 is then inserted into the pin hole 6222. The insertion portion 643 at one end of the pin 640 passes through the second through hole 631, the pin hole 6222, the fixing portion 622, and the ferrule 621, and then enters the light-through hole 6130. The exposed area 652 is exposed on the right side of the fixing member 630 through the avoidance hole 633. The optical fiber protection portion 650 can be connected to the avoidance hole 633 through an interference fit, so that the optical fiber protection portion 650 fills the avoidance hole 633, reducing the gap between the avoidance hole 633 and the optical fiber protection portion 650, and effectively preventing dust from entering the optical module through the gap between the avoidance hole 633 and the optical fiber protection portion 650.

[0275] For the sake of convenience, the plug assembly may include a pin 640 , a fixing member 630 , a fiber optic plug 620 , and a fiber optic protection portion 650 .

[0276] When the plug assembly is inserted into the lower shell 611 of the claw from above the opening of the support part 6112, the lower surface of the optical fiber plug 620 can be inserted obliquely along the transition part 664; the side surface 6224 of the core of the fixing part 622 can be embedded in the right side of the first support step 6612, and the step surface between the side surface 6224 of the core of the fixing part 622 and the core 621 rests against the first support step 6612; the fixing part 622 can slide into the claw from top to bottom along the inclined surface of the first support step 6612.

[0277] The second side surface 6225 of the ferrule of the fixing portion 622 is embedded in the right side of the second support step 66120, and the step surface between the second side surface 6225 of the ferrule of the fixing portion 622 and the ferrule 621 abuts against the second support step 66120. The fixing portion 622 can slide into the claw from top to bottom along the inclined surface of the second support step 66120.

[0278] Insert the optical fiber plug 620 from top to bottom, through the upper opening of the support part 6112, into the lower shell 611 of the claw. During the installation process, the side surface 6224 of the core of the fixed part 622 contacts the first supporting side plate 6610 of the lower shell 611 of the claw. The side surface 6225 of the core of the fixed part 622 contacts the second supporting side plate 6620 of the lower shell 611 of the claw. The left side of the fixed part 622 abuts against the first supporting step 6612 and the second supporting step 66120, which define the relative position of the fixed part 622 and the lower shell 611 of the claw in the left and right directions. The inclined setting of the first supporting step 6612 facilitates the installation of the optical fiber plug 620. The optical fiber ribbon 500 can pass through the optical fiber socket 653 and enter the interior of the claw.

[0279] The left side wall of the bottom plate groove 6642 is positioned in the left-right direction in the same direction as the first support step 6612. As the optical fiber plug 620 is inserted into the claw through the opening of the support member 6112, the ferrule-side surface 6224 of the fixing portion 622 of the optical fiber plug is inserted into the right side of the first support step 6612, and the stepped surface between the ferrule-side surface 6224 of the fixing portion 622 and the ferrule 621 abuts against the first support step 6612, until the bottom surface of the fixing portion 622 is inserted into the bottom plate groove 6642.

[0280] When the bottom surface of the fixing portion 622 is embedded in the bottom plate groove 6642 , the exposed area 652 of the optical fiber protection portion 650 is located between the first lower shell baffle 6643 and the second lower shell baffle 66430 .

[0281] After the optical fiber assembly is secured within the claw lower shell 611, the claw upper shell 612 is inserted into the claw lower shell 611 through the right end. The first upper shell support arm 6128 can slide into the claw lower shell from the right end along the upper surface of the first support side plate 6610. The second upper shell support arm 61280 can slide into the claw lower shell from the right end along the upper surface of the second support side plate 6620. This is done until the side baffle 6114 abuts against the shielding groove 6151, thereby enhancing the sealing of the optical fiber adapter. The first connecting protrusion 6611 is located within the first mounting hole 6141, securing the claw upper shell 612 to the claw lower shell 611. The second connecting protrusion 6621 is located within the second mounting hole 6142, securing the claw upper shell 612 to the claw lower shell 611. The upper shell cover 615 of the upper jaw shell 612 covers the upper opening of the lower jaw shell 611, forming a sealed structure with only left-right light-through holes. This effectively prevents dust from entering the jaw from the top, bottom, and front, back, and sides. The optical fiber protector 650 is connected to the avoidance hole 633 with an interference fit, allowing the optical fiber protector 650 to fill the avoidance hole 633, reducing the gap between the avoidance hole 633 and the optical fiber protector 650. This effectively prevents dust from entering the optical module through the gap between the avoidance hole 633 and the optical fiber protector 650, effectively preventing dust from entering the jaw from the left and right directions.

[0282] The optical fiber protection part 650 and the upper shell 612 of the claw form a gap above the exposed area 652. The fixing part 630 rests on the left side of the upper shell stop arm 6129 of the upper shell 612 of the claw. The lower surface of the upper shell stop arm 6129 is lower than the upper surface of the fixing part 630, thereby blocking the gap above the exposed area 652.

[0283] The optical fiber protection part 650 and the lower shell 611 of the claw form a gap below the exposed area 652, and the fixing part 630 is against the left side of the right side wall of the bottom plate groove 6642. The upper surface of the right side wall of the bottom plate groove 6642 is higher than the lower surface of the fixing part 630, thereby blocking the gap below the exposed area 652.

[0284] In some embodiments, the fixing member 630 is embedded between the first supporting side plate 6610 and the second supporting side plate 6620. The fixing member 630 abuts against the third supporting step 6613, blocking the gap formed behind the exposed area 652 to prevent dust from entering. The fixing member 630 abuts against the fourth supporting step 66130, blocking the gap formed in front of the exposed area 652 to prevent dust from entering.

[0285] In some embodiments, the fixing portion 622 is embedded between the first supporting side plate 6610 and the second supporting side plate 6620. The fixing portion 622 abuts against the first supporting step 6612, thereby blocking the gap formed behind the exposed area 652 and preventing dust from entering. The fixing portion 622 abuts against the second supporting step 66120, thereby blocking the gap formed in front of the exposed area 652 and preventing dust from entering.

[0286] In some embodiments, the length of the avoidance hole 633 in the vertical direction is smaller than the length of the rightmost end of the light-through hole formed by the upper shell 612 of the claw and the lower shell 611 of the claw in the vertical direction. The fixing part 630 blocks the gap formed by the exposed area 652 and the claw 610, which can effectively prevent dust from entering the core 621 through the gap formed by the exposed area 652 and the claw 610.

[0287] The length of the avoidance hole 633 in the front-to-back direction is smaller than the length of the rightmost end of the light-through hole formed by the upper shell 612 of the claw and the lower shell 611 of the claw in the front-to-back direction. The fixing part 630 blocks the gap formed by the exposed area 652 and the claw 610, which can effectively prevent dust from entering the core 621 inside the claw through the gap formed by the exposed area 652 and the claw 610.

[0288] In some embodiments, the optical fiber protection portion 650 and the clamping claw upper shell 612 form a gap above the exposed area 652, and the fixing portion 622 abuts against the left side of the upper shell stop arm 6129 of the clamping claw upper shell 612. The lower surface of the upper shell stop arm 6129 is lower than the upper surface of the fixing portion 622, thereby blocking the gap above the exposed area 652.

[0289] The optical fiber protection part 650 and the lower shell 611 of the claw form a gap below the exposed area 652, and the fixed part 622 rests on the left side of the right side wall of the bottom plate groove 6642. The upper surface of the right side wall of the bottom plate groove 6642 is higher than the lower surface of the fixed part 622, thereby blocking the gap below the exposed area 652.

[0290] The length of the protective hole 6221 of the fixing portion 622 in the vertical direction is smaller than the length of the rightmost end of the light-through hole formed by the upper shell 612 of the claw and the lower shell 611 of the claw in the vertical direction. The fixing part 630 blocks the gap formed by the exposed area 652 and the claw 610, which can effectively prevent dust from entering the core 621 through the gap formed by the exposed area 652 and the claw 610.

[0291] The length of the protective hole 6221 in the front-to-back direction is smaller than the length of the rightmost end of the light-through hole formed by the upper shell 612 of the claw and the lower shell 611 of the claw in the front-to-back direction. The fixing part 630 blocks the gap formed by the exposed area 652 and the claw 610, which can effectively prevent dust from entering the core 621 inside the claw through the gap formed by the exposed area 652 and the claw 610.

[0292] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
