Based on the embodiments provided in the present disclosure, all other embodiments obtained by those skilled in the art are within the scope of protection of the present disclosure.

The term "plurality" means two or more. The term "connected" should be interpreted broadly, for example, "connected" can be fixed connection, or detachable connection, or integral, can be directly connected, or indirectly connected through an intermediate medium. The use of the terms "adapted to" or "configured to" means open and inclusive language, which does not exclude devices adapted or configured to perform additional tasks or steps.

[0084] In optical communication technology, in order to establish information transmission between information processing devices, information is loaded onto light, and the transmission of information is carried out by using the propagation speed of light. Such information-loaded light is an optical signal. The optical signal can reduce the loss of optical power when transmitted in an optical information transmission device, and realize long-distance transmission of the optical signal. At the same time, the cost of optical information transmission devices such as optical fibers is lower than that of electrical information transmission devices such as copper wires. Therefore, optical communication technology can realize high-speed, long-distance, and low-cost information transmission.

[0085] Information processing devices generally include optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, and the like. Optical information transmission devices generally include optical fibers and optical waveguides. The signals that information processing devices can recognize and process are electrical signals, while optical communication technology uses optical signals for transmission, which requires optical modules to convert optical signals and electrical signals.

[0086] Optical modules can realize the mutual conversion of optical signals and electrical signals between information processing devices and optical information transmission devices. In some embodiments, at least one of the optical signal input end or the optical signal output end of the optical module is connected with an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected with an optical network unit; a first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network unit; a second electrical signal from the optical network unit is transmitted to the optical module, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber.

[0087] Since information can be transmitted between multiple information processing devices through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module without all the information processing devices being directly connected to the optical module. Here, the information processing device directly connected to the optical module is also referred to as a host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module is referred to as an optical port, and the electrical signal input end or the electrical signal output end of the optical module is referred to as an electrical port.

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 unlocking component 600 is configured to realize the 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.

[0117] For example, the unlocking component 600 is located outside the two lower side plates 2022 of the lower housing 202, and comprises a clamping component matched with the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the optical module 200 is fixed in the cage 106 by the clamping component of the unlocking component 600; when the unlocking component 600 is pulled, the clamping component of the unlocking component 600 moves accordingly, thereby changing the connection relationship between the clamping component and the host computer, to release the fixation between the optical module 200 and the host computer, so that the optical module 200 can be pulled out of the cage 106.

[0118] In some embodiments, the optical module comprises an optical emission component 400, as shown in Figure 3 and Figure 4 The optical emission component 400 is used for emitting a second optical signal.

[0119] ​In some embodiments, the optical module includes an optical receiving component 500, as shown in Figure 3 and Figure 4 The optical receiving component 500 is configured to receive a first optical signal and convert the first optical signal into an electrical signal.

[0120] In some embodiments, at least one of the optical transmitting component 400 or the optical receiving component 500 is located on a side of the circuit board 300 away from the gold fingers.

[0121] In some embodiments, the optical transmitting component 400 and the optical receiving component 500 are physically separated from the circuit board 300 and are electrically connected to the circuit board 300 through respective flexible circuit boards or electrical connectors.

[0122] In some embodiments, at least one of the optical transmitting component 400 or the optical receiving component 500 can be directly disposed on the circuit board 300. For example, at least one of the optical transmitting component or the optical receiving component can be disposed on a surface of the circuit board 300 or a side of the circuit board 300.

[0123] In some embodiments, the optical transmitting component 400 is connected to a first end of the optical receiving component 500, such that the optical signal emitted by the optical transmitting component 400 is transmitted to the optical receiving component 500.

[0124] In some embodiments, the housing further includes a fiber adapter 700. One end of the fiber adapter 700 can be connected to a second end of the optical receiving component 500, such that an externally inputted received optical signal is inputted to the optical receiving component 500 through the fiber adapter 700, or such that the optical signal emitted by the optical transmitting component 400 and received by the optical receiving component 500 is transmitted to the fiber adapter 700 and then outputted through the fiber adapter 700. The optical receiving component 500 and the optical transmitting component 400 share the fiber adapter 700, and thus the uplink optical signal and the downlink optical signal of the optical module share the optical fiber 101.

[0125] In some embodiments, the lower housing 202 is provided with a protruding portion 2023. The protruding portion 2023, together with a lower side plate of the lower housing 202 and a bottom plate 2021 of the lower housing 202, forms an optical port.

[0126] In some embodiments, the upper housing 201 is provided with a second notch 2012. The second notch 2012 is connected to the protruding portion 2023, such that the upper housing 201 can be covered on the lower housing 202.

[0127] Figure 5 A structural diagram of an unlocking component according to some embodiments is shown in Figure 5 In some embodiments, the unlocking component 600 can include an unlocking handle 610, as shown in

[0128] In some embodiments, the unlocking component 600 can include an unlocking device 620. The unlocking device 620 can be clamped on the lower housing 202 and can slide left and right along the lower housing 202 to achieve unlocking or locking of the optical module.

[0129] In some embodiments, the unlocking component 600 can include a reset elastic member 630. The reset elastic member 630 can be placed in the mounting groove of the lower housing 202, and the reset elastic member 630 can be connected with the unlocking device 620, so that the movement of the unlocking device 620 can compress the reset elastic member 630, or the reset of the reset elastic member 630 can push the unlocking device 620 to move. When the unlocking device 620 slides left along the lower side plate 2022, the unlocking device 620 compresses the reset elastic member 630 to achieve unlocking of the optical module. When the unlocking device 620 does not compress the reset elastic member 630, the reset elastic member 630 pushes the unlocking device 620 to slide right along the lower side plate 2022 to achieve locking of the optical module.

[0130] Figure 6 A structural diagram of an unlocking handle is provided according to some embodiments. As shown in Figure 6 In some embodiments, the unlocking handle 610 can include a hand-held part 611 and symmetrically arranged cantilevers 612. The hand-held part 611 can be placed on the convex part 2023. The hand-held part 611 is bent downward to form a protection part 6111 to reduce the risk of cutting the hand when an operator holds the unlocking handle 610. One end of any cantilever 612 can be connected with the hand-held part 611, so that the unlocking handle 610 forms a U-shaped structure to facilitate rotation of the cantilevers 612 driven by the hand-held part 611. The surface of the cantilever 612 can be outwardly convex to form a first hook 6122. The cantilever 612 can have a rotating hole 6121.

[0131] In some embodiments, the cantilever 612 can have a first inclined surface 6123, i.e., the width dimension of the cantilever 612 is greater than the width dimension of the hand-held part 611, which not only ensures that the strength of the cantilever 612 and the strength of the hand-held part 611 meet the requirements, but also provides more accommodation space for the upper housing 201.

[0132] The protection part 6111 faces the cover plate 2011, and in some embodiments, the first inclined surface 6123 and the protection part 6111 can be located on the same side of the unlocking handle 610, so that the first inclined surface 6123 can be arranged to face the cover plate 2011. The first inclined surface 6123 faces the cover plate 2011, so that the edge of the hand-held part 611 is in contact with the edge of the cover plate 2011 after the optical module is assembled, reducing the probability of assembling the hand-held part 611 on the cover plate 2011.

[0133] Figure 7 A structural diagram of an unlocking device is provided according to some embodiments. As shown in Figure 7As shown, in some embodiments, the unlocking device 620 can include a connecting arm 621 and a supporting arm 622. The first end of the supporting arm 622 can be connected to one end of the connecting arm 621. The connecting arm 621 can be clamped on the bottom plate 2021. The second end of the supporting arm 622 can be clamped on the outer wall of the lower side plate 2022 of the lower shell 202.

[0134] For example, the supporting arm 622 can include a first supporting arm 622a and a second supporting arm 622b. The first end of the first supporting arm 622a can be connected to one end of the connecting arm 621. The first end of the second supporting arm 622b can be connected to the other end of the connecting arm 621. The second end of the first supporting arm 622a can be connected to the outer wall of one of the lower side plates 2022. The second end of the second supporting arm 622b can be connected to the outer wall of another of the lower side plates 2022.

[0135] The first supporting arm 622a and the second supporting arm 622b can be symmetrically arranged along the connecting arm 621. The first supporting arm 622a and the second supporting arm 622b can also be asymmetrically arranged along the connecting arm 621.

[0136] In some embodiments, the supporting arm 622 can include a first placement hole 6221. The first placement hole 6221 can be used to place the first clamping hook 6122. The depth of the first placement hole 6221 can be greater than or equal to the depth of the first clamping hook 6122, so that the first clamping hook 6122 can be placed in the first placement hole 6221 without protruding out of the first placement hole 6221.

[0137] In some embodiments, the first placement hole 6221 can include a first sub-placement hole 6221a. The first sub-placement hole 6221a can be arranged along the height direction of the supporting arm 622. The first clamping hook 6122 can be placed in the first sub-placement hole 6221a.

[0138] When assembling the unlocking device 600, the unlocking handle 610 can be clamped on the outer wall of the shell, and then the unlocking device 620 can be assembled on the outer wall of the lower side plate 2022 from left to right along the length direction of the lower side plate 2022. In some embodiments, the first placement hole 6221 can include a second sub-placement hole 6221b. The second sub-placement hole 6221b can be arranged along the length direction of the supporting arm 622. The first sub-placement hole 6221a and the second sub-placement hole 6221b can be connected to each other, so that the first clamping hook 6122 can move in the first sub-placement hole 6221a and the second sub-placement hole 6221b when assembling the unlocking device 620. This can reduce the contact between the first clamping hook 6122 and the inner surface of the supporting arm 622, and further reduce the deformation of the unlocking device 620 due to expansion, thereby facilitating the assembly of the unlocking device 620.

[0139] In some embodiments, the arm 622 can include a second hook 6222. One end of the second hook 6222 can be connected to one end of the reset elastic member 630, so as to compress the reset elastic member 630 by the second hook 6222, or the reset elastic member 630 resets to push the second hook 6222 to slide to the right. The second hook 622 can be formed by bending the arm 622 inwardly, or can be welded to the inner surface of the arm 622.

[0140] In some embodiments, the arm 622 can include a second storage hole 6223. The arm 622 can include a clamping component 6224. When the optical module 200 is inserted into the cage 106, the clamping component 6224 fixes the optical module 200 in the cage 106; when the unlocking component 600 is pulled, the clamping component 6224 moves accordingly, thereby changing the connection relationship between the clamping component 6224 and the upper computer, to release the fixation of the optical module 200 to the upper computer, so that the optical module 200 can be pulled out of the cage 106.

[0141] In some embodiments, the arm 622 can include a first clamping portion 6226. The bottom surface of the first clamping portion 6226 can be connected to the first connecting arm 621. The arm 622 can include a third clamping portion 6225. The third clamping portion 6225 is provided with the second hook 6222, the second storage hole 6223, and the clamping component 6224.

[0142] The vertical distance between the first clamping portion 6226 of the first arm 622a and the first clamping portion of the second arm 622b is less than the vertical distance between the third clamping portion 6225 of the first arm 622a and the second clamping portion of the second arm 622b, that is, the third clamping portion 6225 protrudes from the first clamping portion 6226, which facilitates placing other devices on the outer wall of the first clamping portion 6226 of the arm 622, while ensuring the width dimension of the optical module. For example, the outer wall of the first clamping portion 6226 of the arm 622 is provided with a clamping plate of the upper housing 201.

[0143] In some embodiments, the arm 622 can include a second clamping portion 6227. One end of the second clamping portion 6227 can be connected to the first clamping portion 6226, and the other end of the second clamping portion 6227 can be connected to the third clamping portion 6225, so as to connect the first clamping portion 6226 and the third clamping portion 6225. The second clamping portion 6227 is inclined relative to the first clamping portion 6226 or the third clamping portion 6225, so that the second clamping portion 6227 can connect the first clamping portion 6226 and the third clamping portion 6225.

[0144] The structure formed by the first clamping portion 6226 and the second clamping portion 6227 is provided with a first storage hole 6221.

[0145] Figure 8A structural diagram of a lower housing according to some embodiments. Figure 9 An assembly diagram of an unlocking handle and a lower housing according to some embodiments. As shown in Figure 8 and Figure 9 In some embodiments, the protrusion 2023 can have a third avoiding surface 2231. The third avoiding surface 2231 can be located on the movement track of the unlocking handle 610. The third avoiding surface 2231 can be an inclined surface to avoid the protection part 6111 of the unlocking handle 610.

[0146] In some embodiments, the lower side plate 2022 can include a first fixing part 2221. The first fixing part 2221 can be arranged corresponding to the cantilever 612, so that the cantilever 612 can be arranged on the outer wall of the first fixing part 2221. The first fixing part 2221 can be arranged corresponding to the first clamping part 6226, so that the first clamping part 6226 can be arranged on the outer wall of the first fixing part 2221. The surface of the first fixing part 2221 can be provided with a rotating shaft 2024. The rotating shaft 2024 can be arranged in the rotating hole 6121 of the unlocking handle 610, so that the unlocking handle 610 is connected with the lower side plate 2022, and then the unlocking handle 610 can rotate along the rotating shaft 2024.

[0147] When installing the unlocking handle 610, the cantilever of the unlocking handle 610 is in contact with the lower side plate of the lower housing 202 opposite to the cantilever. The unlocking handle 610 is moved from top to bottom until the rotating hole 6121 on the cantilever is sleeved on the rotating shaft 2024, so that the unlocking handle 610 can rotate around the rotating shaft 2024.

[0148] In some embodiments, the lower side plate 2022 can include a second fixing part 2222. One end of the second fixing part 2222 can be connected with the first fixing part 2221. The second fixing part 2222 can be arranged corresponding to the first clamping part 6226 of the unlocking device 620, so that the first clamping part 6226 can be arranged on the outer wall of the second fixing part 2222.

[0149] The second fixing part 2222 can include a clamping surface 2222a. The clamping surface 2222a can be arranged along the height direction of the lower side plate 2022. The clamping surface 2222a is perpendicular to the bottom surface of the second fixing part 2222. The clamping surface 2222a can be in contact with the side surface of the cantilever 612.

[0150] The second fixing portion 2222 can include a second avoiding surface 2222b. The second avoiding surface 2222b can be disposed along the height direction of the lower side plate 2022. The top end of the second avoiding surface 2222b can be connected with the bottom end of the clamping surface 2222a. The second avoiding surface 2222b is disposed obliquely with the bottom surface of the second fixing portion 2222, so that the vertical distance between the second avoiding surface 2222b and the side surface of the cantilever 612 is greater than the vertical distance between the clamping surface 2222a and the side surface of the cantilever 612, thereby avoiding the side surface of the cantilever 612.

[0151] In some embodiments, the lower side plate 2022 can include a bearing groove 2027. One end of the bearing groove 2027 can be connected with the other end of the second fixing portion 2222. The bearing groove 2027 can place the third clamping portion 6225 and the second clamping portion 6227 of the unlocking device 620.

[0152] The bearing groove 2027 can include a second bearing plate 2271. The second bearing plate 2271 can be connected with the bottom surface of the third clamping portion 6225 and the second clamping portion 6227 of the arm 622, so as to bear the arm 622.

[0153] The bearing groove 2027 can include a first bearing plate 2272. The bottom surface of the first bearing plate 2272 can be connected with the second bearing plate 2271. One end of the first bearing plate 2272 close to the second fixing portion 2222 can be provided with a connecting portion 2273. The connecting portion 2273 is disposed obliquely relative to the second fixing portion 2222, and the connecting portion 2273 can be correspondingly disposed with the second clamping portion 6227, so that the second clamping portion 6227 of the unlocking device 620 can be disposed on the outer wall of the connecting portion 2273.

[0154] In some embodiments, the first bearing plate 2272 can be provided with a mounting groove 2025. The mounting groove 2025 can be disposed along the length direction of the lower side plate 2022. The mounting groove 2025 can place the reset elastic member 630. For example, one side wall of the mounting groove 2025 can be connected with the other end of the reset elastic member 630.

[0155] The mounting groove 2025 can have an opening 2251. The opening 2251 can be disposed towards the arm 622 of the unlocking device 620, so that the second clamping hook 6222 of the arm 622 can move back and forth along the mounting groove 2025, thereby causing the reset elastic member 630 in the mounting groove 2025 to be compressed or reset along with the second clamping hook 622.

[0156] When the optical module 200 is assembled, the unlocking handle 610 is first clamped on the outer wall of the shell, and then the unlocker 620 is assembled on the outer wall of the lower side plate 2022 from left to right along the length direction of the lower side plate 2022, and then the reset elastic member 630 is placed in the mounting groove 2025, and finally the upper shell 201 is clamped on the lower shell 202. Since the unlocker 620 has been assembled on the outer wall of the lower side plate 2022 before the reset elastic member 630 is placed in the mounting groove 2025, the unlocker 620 blocks the opening 2251 of the mounting groove 2025 facing the unlocker 620. In order to place the reset elastic member 630 in the mounting groove 2025, in some embodiments, the mounting groove 2025 can be provided with a first gap 2252 facing the cover plate 2011. The reset elastic member 630 can be placed in the mounting groove 2025 through the first gap 2252.

[0157] In some embodiments, the first bearing plate 2272 can be provided with a second clamping protrusion 2026. The second clamping protrusion 2026 can be placed in the second storage hole 6223. The length dimension of the second clamping protrusion 2026 is smaller than the length dimension of the second storage hole 6223, and the width dimension of the second clamping protrusion 2026 is smaller than or equal to the width dimension of the second storage hole 6223, so that the second clamping protrusion 2026 can move back and forth in the second storage hole 6223, reducing the unlocker 620 from the lower side plate 2022.

[0158] In some embodiments, the upper surface of the first bearing plate 2272 can bear the upper shell 201. The upper surface of the first bearing plate 2272 can include a first bearing surface 2223. The first bearing surface 2223 can be located above the mounting groove 2025. The first bearing surface 2223 and the communication of the mounting groove 2025 form a first gap 2252.

[0159] The upper surface of the first bearing plate 2272 can include a second bearing surface 2224. The second bearing surface 2224 is farther away from the rotation axis 2024 than the first bearing surface 2223. The first bearing surface 2223 and the second bearing surface 2224 can have a height difference.

[0160] The upper surface of the first bearing plate 2272 can include a third bearing surface 2225. The third bearing surface 2225 and the first bearing surface 2223 can be located on the same side of the second bearing surface 2224. The third bearing surface 2225 can be provided adjacent to the first bearing surface 2223. The third bearing surface 2225 is farther away from the opening of the mounting groove 2025 than the first bearing surface 2223. The third bearing surface 2225 and the second bearing surface 2224 can have a height difference, and the third bearing surface 2225 and the first bearing surface 2223 can have a height difference.

[0161] Figure 10FIG1 is an assembly diagram of an unlocking component and a lower housing according to some embodiments. Figure 10 As shown, in some embodiments, the area of ​​the first clamping portion 6226 of the support arm 622 of the unlocker 620 except the first storage hole 6221 is clamped on the cantilever 612 and the second fixed portion 2222 of the unlocking handle 610, and the first hook 6122 is placed in the first storage hole 6221 of the support arm 622 to fix the unlocker 620 to the unlocking handle 610, so that the first hook 6122 pushes the unlocker 620 to move.

[0162] The connecting arm 621 of the unlocker 620 is clamped on the bottom plate 2021 of the lower shell 202, the third clamping portion 6225 of the support arm 622 of the unlocker 620 is clamped on the supporting groove 2027 of the lower shell 202, and the second clamping portion 6227 of the support arm 622 of the unlocker 620 is clamped on the connecting portion 2273 of the lower shell 202, so that the unlocker 620 is fixedly connected to the lower shell 202.

[0163] Figure 11 This is a structural diagram of an upper shell provided according to some embodiments. Figure 12 A cross-sectional view of an optical module according to some embodiments Figure 1 . Figure 13 A cross-sectional view of an optical module according to some embodiments Figure 2 .like Figure 11 、 Figure 12 、 Figure 13 As shown, in some embodiments, the lower surface of the cover plate 2011 may include a second covering surface 2111. The second covering surface 2111 may be disposed corresponding to the third supporting surface 2225 of the first supporting plate 2272. The second covering surface 2111 may be in contact with and connected to the third supporting surface 2225 of the first supporting plate 2272, so that the second covering surface 2111 covers the third supporting surface 2225.

[0164] In some embodiments, the lower surface of the cover plate 2011 may include a third covering surface 2112. The third covering surface 2112 may be disposed corresponding to the second bearing surface 2224. The third covering surface 2112 may be in contact with and connected to the second bearing surface 2224.

[0165] In some embodiments, the lower surface of the cover plate 2011 may be provided with two fourth covering surfaces 2115. One side of the fourth covering surface 2115 is connected to the second covering surface 2111, so that the second covering surface 2111 is located between the two fourth covering surfaces 2115. The fourth covering surface 2115 and the second covering surface 2111 are both located on the same side of the third covering surface 2112. The fourth covering surface 2115 is closer to the edge of the cover plate 2011 than the second covering surface 2111. The fourth covering surface 2115 is connected to the side of the second covering surface 2111.

[0166] The area between the edge of the fourth cover surface 2115 connected with the second cover surface 2111 and the clamping plate 2013 can be in contact with the top surface of the support arm 622, so that the clamping plate 2013 can be clamped on the outer wall of the support arm 622.

[0167] The fourth cover surface 2115 protrudes outward relative to the second cover surface 2111, that is, the fourth cover surface 2115 has a height difference with the second cover surface 2111, so as to increase the contact area of the upper shell 201 and the lower shell 202 and improve the connection stability of the upper shell 201 and the lower shell 202.

[0168] The first cover surface 2116 can be arranged on the fourth cover surface 2115. The first cover surface 2116 can be arranged correspondingly with the first bearing surface 2223. The first cover surface 2116 can be in contact with the first bearing surface 2223.

[0169] The first cover surface 2116 protrudes outward relative to the second cover surface 2111, that is, the first cover surface 2116 has a height difference with the second cover surface 2111, so as to improve the connection stability of the upper shell 201 and the lower shell 202.

[0170] The second cover surface 2111, the third cover surface 2112 and the first cover surface 2116 all have height differences, further increasing the contact area of the upper shell 201 and the lower shell 202 and further improving the connection stability of the upper shell 201 and the lower shell 202.

[0171] The first clamping protrusion 2117 can be arranged on the first cover surface 2116. The first clamping protrusion 2117 can be arranged correspondingly with the first notch 2252 of the mounting groove 2025. The first clamping protrusion 2117 can be arranged at the first notch 2252 of the mounting groove 2025, so as to increase the contact area of the upper shell 201 and the lower shell 202 and improve the connection stability of the upper shell 201 and the lower shell 202.

[0172] In some embodiments, the lower surface of the cover plate 2011 can be provided with a first avoiding surface 2113. One end of the first avoiding surface 2113 can be connected with the end surface of the cover plate 2011 close to the protruding portion 2023. The other end of the first avoiding surface 2113 can be connected with the fourth cover surface 2115. The first avoiding surface 2113 can be arranged correspondingly with the first inclined surface 6123 of the unlocking handle 610. The first avoiding surface 2113 is an inclined surface, and the inclination angle of the first avoiding surface 2113 is greater than or equal to the inclination angle of the first inclined surface 6123, so that the first avoiding surface 2113 can avoid the first inclined surface 6123 of the unlocking handle 610.

[0173] When the unlocking handle 610 rotates along the rotation axis 2024, driving the unlocking mechanism 620, the force exerted by the first hook 6122 of the unlocking handle 610 on the unlocking mechanism 620 can be decomposed into a first force component parallel to the lower side plate and a second force component perpendicular to the lower side plate. The first force component pushes the unlocking mechanism to the left, while the second force component pushes the unlocking mechanism outward. The outward expansion of the unlocking mechanism causes the unlocking mechanism to disengage from the first hook of the unlocking handle, resulting in the unlocking mechanism failing. To address this issue, in some embodiments, a snap-on plate 2013 may be provided at one end of the cover plate 2011 near the raised portion 2023. The snap-on plate 2013 may be located on the outer edge of the cover plate 2011. The snap-on plate 2013 may be positioned corresponding to the first snap-on portion 6226 of the unlocking mechanism 620, such that the snap-on plate 2013 is positioned on the outer wall of the first snap-on portion 6226. This can reduce the possibility of the unlocking mechanism 620 failing due to its outward expansion during sliding.
