Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0104] Unless otherwise required by the context, throughout the specification and claims, the term "comprising" is interpreted to mean "including, but not limited to"; the terms "first", "second", etc. are not used to indicate relative importance or to indicate the upper limit of the number; the term "multiple" means two or more; the term "connected" should be interpreted broadly, for example, "connected" can be fixedly connected, or detachably connected, or integrated, 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 to or configured to perform additional tasks or steps; the terms "parallel", "vertical", "same", "consistent", "flush", etc. are not limited to absolute mathematical relationships, but also include acceptable error ranges generated in practice, and differences formed based on the same design concept but due to manufacturing reasons.

[0105] 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. Optical signals can reduce the loss of optical power when transmitted in optical information transmission devices, and realize long-distance transmission of optical signals. 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.

The second fiber adapter 720 can be clamped at the second sub-through hole 9132, so that the second fiber adapter 720 is sealingly connected with the shielding plate 910.

[0163] In some embodiments, the shielding gasket assembly 920 can include a third through hole 923. The fiber adapter 700 can be clamped at the third through hole 923 of the shielding plate 910, so that the fiber adapter 700 is sealingly connected with the shielding gasket assembly 920.

[0165] Figure 8aA structural diagram of a shielding plate according to some embodiments. Figure 8b A structural diagram of a shielding plate according to some embodiments from another perspective. As shown in Figure 8a and 8b In some embodiments, the shielding plate 910 can include a flat portion 911. The bottom of the flat portion 911 can be placed in the first storage groove of the lower housing 202. The flat portion 911 can be provided with a first sub-through hole 9131 and a second sub-through hole 9132. The flat portion 911 can be provided with a second gap 914, which can be located between the first sub-through hole 9131 and the second sub-through hole 9132, and the second gap 914 can avoid the structural member of the lower housing.

[0166] The flat portion 911 can include a first side surface 9111, which can face the optical port of the optical module, and the first side surface 9111 can be connected with the limiting surface of the lower housing 202. The flat portion 911 can include a second side surface 9112, which can face the electrical port of the optical module, and the second side surface 9112 is arranged opposite to the first side surface 9111, and the second side surface 9112 can be connected with the side surface of the second clamping portion 702 of the fiber optic adapter 700 close to the optical port.

[0167] In some embodiments, the flat portion 911 can include a plurality of convex points 9113. The convex points 9113 can increase the thickness dimension of the flat portion 911 and reduce the gap between the convex points 9113 and the side surface corresponding to the convex points 9113. The convex points 9113 can protrude from the first side surface 9111 of the flat portion 911, so that the convex points 9113 can protrude towards the optical port of the optical module 200, so that the convex points 9113 can be in contact with the limiting surface of the lower housing 202, not only meeting the size of the optical port of the optical module, but also increasing the contact area of the shielding plate and the lower housing, so that the shielding plate and the lower housing are sealedly connected, and the electromagnetic shielding effect is improved.

[0168] In some embodiments, the convex points 9113 can be arranged at the edge region of the flat portion 911. The convex points 9113 at the edge region of the flat portion 911 can abut against the first limiting surface of the lower housing 202.

[0169] In some embodiments, the convex points 9113 can be arranged at the middle region of the flat portion 911, above the second gap 914. The convex points 9113 at the middle region of the flat portion 911 can abut against the second limiting surface of the lower housing 202.

[0170] In some embodiments, the shielding plate 910 can include a raised portion 912. The bottom of the raised portion 912 can be connected with the top of the flat portion 911, and the raised portion 912 can be located above the flat portion 911, so that the raised portion 912 is the top of the shielding plate 910, and the flat portion 911 is the bottom of the shielding plate 910. The top of the raised portion 912 is a free end. The raised portion 912 can be connected with the upper shell 201 in an interference fit, so that the shielding plate 910 and the upper shell 201 can be connected in a sealed manner, and the electromagnetic shielding effect can be achieved.

[0171] In some embodiments, the first bending area of the raised portion 912 can be connected with the upper shell 201 in an interference fit. The first bending area of the raised portion 912 is the bending area of the raised portion 912 closest to the flat portion 911.

[0172] In some embodiments, other areas of the raised portion 912 can be connected with the upper shell 201 in an interference fit. The other areas of the raised portion 912 are areas of the raised portion 912 other than the first bending area.

[0173] Compared with the first bending area of the raised portion 912 connected with the upper shell 201 in an interference fit, the other areas of the raised portion 912 connected with the upper shell 201 in an interference fit are prone to cause the first through hole 913 of the shielding plate 910 to deform, resulting in that the first through hole 913 of the shielding plate 910 and the fiber optic adapter 700 cannot be connected in a sealed manner. In addition, when the other areas of the raised portion 912 are connected with the upper shell 201, there can be gaps, so that the raised portion 912 and the upper shell 201 cannot be connected in a sealed manner. In order to ensure that the raised portion 912 and the upper shell 201 are connected in a sealed manner, in some embodiments, the first bending area of the raised portion 912 can be connected with the upper shell 201 in an interference fit, and the other areas of the raised portion 912 are not connected with the upper shell 201. The first bending area of the raised portion 912 connected with the upper shell 201 in an interference fit and the other areas of the raised portion 912 not connected with the upper shell 201 can ensure that the first bending area of the raised portion 912 is connected with the upper shell 201 in an interference fit, so that the raised portion 912, the upper shell 201, and the fiber optic adapter 700 are connected in a sealed manner.

[0174] The raised portion 912 can include a second raised portion 9122. The bottom of the second raised portion 9122 is connected with the top of the flat portion 911. The top of the second raised portion 9122 can be the top of the raised portion 912, or the top of the shielding plate 910.

[0175] In some embodiments, the second raised portion 9122 is curved towards the optical port relative to the flat portion 911.

[0176] In some embodiments, the second raised portion 9122 is curved towards the electrical port relative to the flat portion 911.

[0177] The second protruding portion 9122 is curved towards the optical port or the electrical port relative to the flat portion 911, and the second protruding portion 9122 is more easily curved after being subjected to downward pressure.

[0178] The protruding portion 912 can include a first protruding portion 9121. The bottom of the first protruding portion 9121 can be the bottom of the protruding portion 912 and can be connected to the top of the flat portion 911. The top of the first protruding portion 9121 can be the bottom of the protruding portion 912 and can be connected to the bottom of the second protruding portion 9122. The presence of the first protruding portion 9121 can increase the elasticity of the protruding portion 912 and thus increase the elasticity of the shielding plate 910. The increase in the elasticity of the shielding plate 910 can not only reduce the support force of the upper shell on the shielding plate 910 during assembly of the optical module, thereby reducing the lifting of the upper shell, so that the shielding plate and the upper shell can be sealingly connected to achieve electromagnetic shielding, but also reduce the deformation of the shielding plate 910, so that the shielding plate 910 and the fiber optic adapter 700 can be sealingly connected to achieve electromagnetic shielding.

[0179] In some embodiments, the first protruding portion 9121 is curved towards the optical port relative to the flat portion 911.

[0180] In some embodiments, the first protruding portion 9121 is curved towards the electrical port relative to the flat portion 911.

[0181] The first protruding portion 9121 is curved towards the optical port or the electrical port relative to the flat portion 911, and the first protruding portion 9121 is more easily curved after being subjected to downward pressure.

[0182] The first protruding portion 9121 and the second protruding portion 9122 are both curved relative to the flat portion 911, and the directions of the curvatures of the first protruding portion 9121 and the second protruding portion 9122 are opposite, which can increase the elasticity of the protruding portion 912 without occupying the space of other devices.

[0183] The first protruding portion 9121 is curved towards the optical port relative to the flat portion 911, and the second protruding portion 9122 is curved towards the electrical port relative to the flat portion 911, so that the connection between the bottom of the second protruding portion 9122 and the top of the first protruding portion 9121 protrudes towards the optical port, that is, the first bending area of the protruding portion 912 protrudes towards the optical port.

[0184] The first protruding portion 9121 is curved towards the electrical port relative to the flat portion 911, and the second protruding portion 9122 is curved towards the optical port relative to the flat portion 911, so that the connection between the bottom of the second protruding portion 9122 and the top of the first protruding portion 9121 protrudes towards the electrical port, that is, the first bending area of the protruding portion 912 protrudes towards the electrical port.

[0185] The first bending area of the protruding part 912 protrudes towards the optical port or the electrical port, which can increase the elasticity of the shielding plate 910 without affecting the placement of other devices in the optical module, so that the optical module assembly process will not generate a large supporting force on the upper shell 201 when the shielding plate 910 is pressed down by the upper shell 201, thereby reducing the lifting of the upper shell 201, so that the shielding plate and the upper shell can be sealingly connected to achieve electromagnetic shielding.

[0186] The first bending area of the protruding part 912 protrudes towards the optical port, and the first bending area of the protruding part 912 is the area closest to the optical port in the protruding part 912. The first bending area of the protruding part 912 protrudes towards the electrical port, and the first bending area of the protruding part 912 is the area farthest from the optical port in the protruding part 912. Therefore, the first bending area of the protruding part 912 protrudes towards the optical port, and the first bending area of the protruding part 912 is sealingly connected to the upper shell 201, so that the propagation path of the electromagnetic wave is longer, the reflection path of the electromagnetic wave is longer, and the electromagnetic shielding effect is better.

[0187] The protruding part 912 can include a third protruding part, the bottom of the third protruding part can be connected to the top of the second protruding part 9122, the connection between the second protruding part 9122 and the third protruding part is a second bending area, and the top of the third protruding part is a free end. The second bending area is farther away from the flat part than the first bending area.

[0188] In some embodiments, the second protruding part 9122 can include a first notch 9123, and the presence of the first notch 9123 allows the second protruding part 9122 to be divided into multiple fins. The area of a single fin is small and is more likely to bend under stress, and the bending of a single fin under stress will not affect other fins. Therefore, the second protruding part 911 includes the first notch 9123 to reduce the strength of the second protruding part 9122, increase the elasticity of the second protruding part 9122, so that the second protruding part 9122 is more likely to bend under stress, thereby reducing the deformation of the shielding plate 910.

[0189] Figure 9 An exploded view of a shielding gasket assembly according to some embodiments. As shown in FIG. 1, the shielding gasket assembly includes a shielding plate 910 and an upper shell 201. The shielding plate 910 includes a flat part 9101 and a protruding part 912.

The bottom of the second shielding gasket 922 is in contact with the top of the first shielding gasket 921, so that the shielding gasket assembly 920 can have the third sub-through hole 9232 and the fourth sub-through hole 9231.

[0190] The first shielding gasket 921 and the second shielding gasket 922 are relatively soft relative to the shielding plate 910, and can fill the gap between the fiber optic adapter 700 and the housing, so that the fiber optic adapter 700 is in sealed connection with the housing.

[0191] The shielding plate 910 and the shielding gasket assembly 920 cooperate, so that the fiber optic adapter 700 can be in sealed connection with the housing and the shielding plate 910, so as to improve the electromagnetic shielding effect of the optical module.

[0193] In some embodiments, the end of the lower side plate 2022 close to the limiting plate 2023 can be inwardly convex to form a first support surface 2221.

This not only meets the optical port size of the optical module, but also increases the contact area between the shielding plate and the lower housing, so that the shielding plate and the lower housing are sealed together and the electromagnetic shielding effect is improved.

[0212] like Figure 11a As shown, there is a gap between the second side of the flat portion 911 of the shielding plate 910 and the second snap-fit ​​groove 2272 to facilitate the placement and removal of the shielding plate 910.

Figure 11d A partial view of an internal structure of an optical module according to some embodiments Figure 4 . Figure 11b An assembly view of the lower housing and the shielding plate and the first shielding gasket. As shown in Figure 11b , Figure 11c and Figure 11d , in some embodiments, the first shielding gasket 921 is placed on the first support plate 2026, and the radius of curvature of the first shielding gasket 921 is the same as that of the first clamping groove 2271, so that the third clamping groove 9211 of the first shielding gasket 921 is flush with the first clamping groove, and the new clamping groove formed by the third clamping groove of the first shielding gasket 921 and the first clamping groove can clamp the third clamping portion 703 of the fiber optic adapter 700. For example, the fifth sub-clamping groove 9211a of the first shielding gasket 921 and the first sub-clamping groove 22712 form a first new sub-clamping groove, and the third clamping portion 703 of the first fiber optic adapter 710 is clamped in the first new sub-clamping groove. The sixth sub-clamping groove 9211b of the first shielding gasket 921 and the second sub-clamping groove 22711 form a second new sub-clamping groove, and the third clamping portion 713 of the second fiber optic adapter 720 is clamped in the second new sub-clamping groove.

[0214] As shown in Figure 11b , Figure 11c and Figure 11d , the second shielding gasket 922 is placed above the top of the first shielding gasket 921, and the fourth clamping groove 9221 covers the new clamping groove, so that the fourth clamping groove 9221 and the new clamping groove form a second through hole, and the second through hole is clamped in the third clamping portion 703 of the fiber optic adapter 700, so that the third clamping portion 703 is in sealed connection with the second through hole.

[0215] As shown in Figure 11b , Figure 11c and Figure 11dAs shown, the first snap-fit ​​portion 711 of the first fiber optic adapter 710 snaps into the first sub-through hole 9131 and extends across the first sub-through hole 9131; the second snap-fit ​​portion 712 of the first fiber optic adapter 710 snaps into the third sub-snap slot 27222 and is suspended above the first sub-storage slot 2281, with the end face of the second snap-fit ​​portion 712 of the first fiber optic adapter 710 contacting and connecting with the second side surface of the flat portion 911 of the shielding plate 910.

[0216] In some embodiments, the radius of the first through hole 913 is greater than or equal to the radius of the first latching part 701 and less than or equal to the radius of the second latching part 702, so that the first latching part 701 latches onto the first through hole 913 and the second latching part 702 stops at the shielding plate 910, so that the second latching part 702 can be connected to the side of the shielding plate 910 facing away from the optical port, thereby making the shielding plate 910 and the fiber optic adapter 700 sealed together.

[0217] Figure 12 This is a structural diagram of an upper housing according to some embodiments. Figure 13a A cross-sectional view of an optical module according to some embodiments. Figure 1 . Figure 13b A cross-sectional view of an optical module according to some embodiments. Figure 2 .like Figure 12 , Figure 13a and Figure 13b As shown, in some embodiments, the upper housing 201 may include an upper side plate 2012, which is connected to the cover plate 2011.

[0218] In some embodiments, the upper housing 201 may include a second support plate 2013. The second support plate 2013 may be disposed on the inner surface of the cover plate 2011. Both ends of the second support plate 2013 may be connected to the upper side plate 2012. The second support plate 2013 may support the second shielding gasket 922.

[0219] In some embodiments, the upper housing 201 may include a fastener 2014. The fastener 2014 and the second support plate 2013 form a second storage slot 2015, which can accommodate the protrusion 912 of the shielding plate 910.

[0220] The fastener 2014 may include a first fixing surface 2142, which may be located at one end of the fastener 2014 near the second storage slot 2015. The first fixing surface 2142 may be in contact with the second support surface 2242 of the lower housing 202.

[0221] The fastener 2014 may include a second fixing surface 2141. The second fixing surface 2141 may be located at one end of the fastener 2014 away from the second storage slot 2015. The second fixing surface 2141 may be in contact with the first support surface 2221 of the lower housing 202.

[0222] The fastener 2014 may include a fourth fastening surface 2143. The fourth fastening surface 2143 may be located at one end of the fastener 2014 away from the second storage slot 2015. The fourth fastening surface 2143 may be recessed relative to the second fastening surface 2141 to avoid the fiber optic connector 800.

[0223] The fastener 2014 may include a third fastening surface 2144. The third fastening surface 2144 may be located at one end of the fastener 2014 away from the second storage slot 2015. The third fastening surface 2144 may be located between two fourth fastening surfaces 2143. The third fastening surface 2144 may be more recessed relative to the fourth fastening surfaces 2143.

[0224] The fastener 2014 may include a first storage hole 2145, which extends from the third fixing surface 2144 toward the side opposite to the third fixing surface 2144. The first storage hole 2145 may be located between two fourth fixing surfaces 2143, that is, the fourth fixing surfaces 2143 may be located between the first storage hole 2145 and the second fixing surface 2141. The third fixing surface 2144 may be in contact with the third support surface 2241. The first storage hole 2145 is correspondingly provided with the second storage hole 2243 of the lower housing 202. A screw passes through the first storage hole 2145 and enters into the second storage hole 2243 to fix the upper housing 201 and the lower housing 202 together.

[0225] The fixing surface where the first storage hole 2145 is located can be recessed relative to the second fixing surface 2141 to increase the contact area between the upper housing 201 and the lower housing 202 and improve the connection stability between the upper housing 201 and the lower housing 202.

[0226] Figure 13c A cross-sectional view of an optical module according to some embodiments. Figure 3 .like Figure 13c As shown, the second notch 914 of the shielding plate 910 is engaged with the first blocking part 22731 to increase the contact area between the shielding plate 910 and the lower housing 202 and improve the connection stability between the shielding plate 910 and the lower housing 202.

[0227] Figure 13d A cross section of an optical module according to some embodiments Figure 4 As shown in Figure 13d The protruding part 912 can be placed in the second storage groove 2015 so that the second storage groove 2015 can accommodate the protruding part 912.

[0228] The first protruding part 9121 and the second protruding part 9122 are both curved relative to the flat part 911, and the directions of their curvatures are opposite, which can increase the size of the protruding part 912 in the length direction of the optical module, so as to fill the second storage groove 2015.

[0229] As shown in Figure 13d The top of the second shielding gasket 922 is in contact with the second support plate 2013, the bottom of the second shielding gasket 922 is in contact with the upper half of the third clamping part 703 of the first fiber adapter 710, and the lower half of the third clamping part 703 of the first fiber adapter 710 is connected with the top of the first shielding gasket 921 and the top surface of the structure where the second sub-clamping groove 22711 is located.

[0230] The side wall of the second support plate 2013 is a side wall of the second storage groove 2015, the first protruding part 9121 and the second protruding part 9122 are both curved relative to the flat part 911, and the directions of their curvatures are opposite, which can increase the size of the protruding part 912 in the length direction of the optical module without affecting the second shielding gasket 922, and increase the elasticity of the shielding plate 910.

[0231] The first bending area of the protruding part 912 is in interference connection with the upper shell 201, and the connection of other areas of the protruding part 912 with the upper shell 201 is prone to cause deformation of the first through hole 913 of the shielding plate 910, resulting in that the first through hole 913 of the shielding plate 910 and the fiber adapter 700 cannot be sealed and connected. In addition, when the other areas of the protruding part 912 are connected with the upper shell 201, there may be a gap, so that the protruding part 912 and the upper shell 201 cannot be sealed and connected, and the distance between the inner side wall of the second storage groove 2015 and the flat part 911 of the shielding plate 910 is limited.

[0232] In order to ensure that the protruding part 912 is sealed and connected with the upper shell 201, in some embodiments, the first bending area of the protruding part 912 is in interference connection with the inner wall of the second storage groove 2015, and the other areas of the protruding part 912 are not connected with the inner wall of the second storage groove 2015, so as to ensure that the first bending area of the protruding part 912 is in interference connection with the inner wall of the second storage groove 2015, so that the protruding part 912 is sealed and connected with the inner wall of the second storage groove 912, and electromagnetic shielding is realized.

[0233] As shown in Figure 13dAs shown, the first fixing surface 2142 is protruded relative to the second support plate 2013, that is, an inner side wall of the second storage groove 2015 close to the light port is protruded relative to an inner side wall of the second storage groove 2015 away from the light port, and the first bending area of the protruding part 912 is protruded towards the light port, so that the first bending area of the protruding part 912 is in interference connection with the inner side wall of the second storage groove 2015 close to the light port, the propagation path of the electromagnetic wave is longer, the reflection path of the electromagnetic wave is longer, and the electromagnetic shielding effect is better.

[0234] In some embodiments, the height dimension (along the height direction of the optical module) of the second storage groove 2015 is smaller than the height dimension of the protruding part 912, and the length dimension (along the length direction of the optical module) of the second storage groove 2015 is smaller than the length dimension of the protruding part 912, so that the second storage groove 2015 can place the protruding part 912.

The second mounting groove 2306 can be farther away from the engaging component 2029 relative to the first mounting groove 2303. The second mounting groove 2306 can be formed by the side wall of the first mounting groove 2303 being recessed inward away from the first recess 2212, so that the second mounting groove 2306 can be more recessed relative to the first mounting groove 2303.

[0253] In some embodiments, the first protrusion 612 can form a first avoiding groove 614. The first avoiding groove 614 can avoid the protruding area of the unlocking device 620. The protruding area of the unlocking device 620 is placed in the first avoiding groove 614, so that the distance between the top of the first protrusion 612 and the protruding area of the unlocking device 620 is close, facilitating the top of the first protrusion to press the protruding area of the unlocking device 620 to achieve the sliding of the unlocking device pushed by the first protrusion.

[0254] In some embodiments, the rotating shaft 611 can be formed with a third avoiding groove, and the third avoiding groove and the first avoiding groove 614 can avoid the protruding area of the unlocking device 620.

[0255] In some embodiments, the unlocking handle 610 can include a connecting piece 613. One end of the connecting piece 613 is connected with one end of the rotating shaft 611, and the other end of the connecting piece 613 is connected with the other end of the rotating shaft 611, so that the connecting piece 613 is connected with the rotating shaft 611, and the connecting piece 613 can move with the rotating shaft 611.

[0256] The connecting piece 613 can include a second connecting column 6132 and two symmetrically arranged first connecting columns 6131. The two ends of the second connecting column 6132 are respectively connected with the first connecting column 6131 and the second connecting column 6132, so that the shape of the connecting piece 613 is U-shaped. One of the first connecting columns 6131 is connected with one end of the rotating shaft 611, and the other first connecting column 6131 is connected with the other end of the rotating shaft 611, so that the connecting piece 613 is connected with the rotating shaft 611. The first connecting column 6131 is clamped on the outer side wall of the lower side plate 2022, and the second connecting column 6132 is clamped on the top of the lower side plate 2022, so that the connecting piece 613 can be connected with the lower side plate 2022.

[0257] In some embodiments, the second connecting column 6132 can be provided with a second avoiding groove 6133. The first elastic sheet is inclinedly arranged, and the second avoiding groove 6133 is inclinedly arranged, so that the second avoiding groove 6133 can avoid the first elastic sheet of the fiber connector 800.

[0258] In some embodiments, the first connecting column 6131 can be clamped in the third mounting groove 2223, so that the first connecting column 6131 is clamped on the outer side wall of the lower side plate 2022.

[0259] In some embodiments, the first connecting column 6131 can form a first avoiding notch 6134. The first avoiding notch 6134 can be recessed towards the optical port. Compared with the first connecting column 6131 without the first avoiding notch 6134, the first connecting column 6131 with the first avoiding notch 6134, the position of the second connecting column 6132 clamped on the lower housing 202 is farther away from the optical port, and the distance between the second connecting column 6132 and the bottom plate 2021 of the lower housing 202 is shorter, so that the height dimension of the unlocking handle 610 meets the protocol requirements.

[0260] The first connecting column 6131 can include a first connecting part 61311 and a second connecting part 61312. The first end of the first connecting part 61311 can be connected with one end of the rotating shaft 611, the second end of the first connecting part 61311 can be connected with the first end of the second connecting part 61312, and the second end of the second connecting part 61312 can be connected with the second connecting column 6132. The connection between the first connecting part 61311 and the second connecting part 61312 can form the first avoiding notch 6134.

[0261] In some embodiments, the first avoiding notch 6134 can be flush with the eighth avoiding notch 2224 of the lower side plate 2022, or the first avoiding notch 6134 can be recessed relative to the eighth avoiding notch 2224, so as to leave out the optical port of the optical module, and facilitate the insertion of the first fiber connector 810 and the second fiber connector 820 into the optical port.

[0262] In some embodiments, a snap-fit ​​notch 6135 may be formed at the connection between the first connecting portion 61311 and the second connecting portion 61312. The snap-fit ​​notch 6135 may protrude toward the optical port. The snap-fit ​​notch 6135 and the first clearance notch 6134 may be disposed opposite to each other. The snap-fit ​​notch 6135 may snap into the third mounting groove portion 22233 of the third mounting groove 2223, the first connecting portion 61311 connected to the snap-fit ​​notch 6135 may snap into the first mounting groove portion 22231, and the second connecting portion 61312 connected to the snap-fit ​​notch 6135 may snap into the second mounting groove portion 22232, so that the first connecting post 6131 may snap into the third mounting groove 2223.

[0263] Compared to the first connecting post 6131 which does not have a snap-fit ​​notch 6135, the first connecting post 6131 with a snap-fit ​​notch 6135 can increase the contact area between the first connecting post 6131 and the third mounting groove 2223, thereby improving the connection stability between the first connecting post 6131 and the lower side plate 2022.

The clamping surface 6213 can be located between the bottom plate 2021 and the top surface of the first sliding part 621, so as to reduce the thickness of the first sliding part 621, so that the thickness dimension of the inclined structure 6214 meets the requirements. The clamping surface 6213 can be located between the side of the hollow groove 6211 close to the clamping part 2029 and the side of the hollow groove 6211 away from the clamping part 2029, so that the maximum thickness of the hollow groove 6211 is greater than or equal to the thickness dimension of the elastic reset member 630, thereby reducing the probability of the elastic reset member 630 disengaging from the hollow groove 6211.

[0271] In order to cooperate with the clamping surface 6213, the bottom plate 2021 is provided with a first recess 2212. The clamping surface 6213 can slide in the first recess 2212, but stop before the third limiting surface 2213.

[0272] In some embodiments, the top surface of the second sliding part 622 protrudes from the top surface of the first sliding part 621, so that the fixed plate 203 can limit the position of the second sliding part 622.

[0273] In some embodiments, the edge region of the second sliding part 622 cooperates with the edge region of the first protrusion 612, so that the edge region of the other end of the second sliding part 622 is connected with the edge region of the first protrusion 612. The bottom surface of the second sliding part 622 is recessed relative to the bottom surface of the first sliding part 621, so that the unlocker 620 forms a second avoiding gap 624. The second avoiding gap 624 can avoid the connecting wall 6121 of the first protrusion 612.

The one side of the first avoiding slot 614 is connected with the other side of the first avoiding slot 614.

[0277] The inclined surface 6231 of the unlocker 620 is located in the first avoiding slot 614, so that the distance between the top of the first protrusion 612 and the inclined surface 6231 of the unlocker 620 is close, facilitating the top of the first protrusion 612 to press the inclined surface 6231 of the unlocker 620, so as to realize the sliding of the unlocker 620 pushed by the first protrusion 612.

[0278] In some embodiments, the bottom surface 6232 of the second protrusion 623 is different in height from the bottom surface of the first sliding part 621, such that the bottom surface of the second protrusion 623 and the bottom surface of the first sliding part 621 form a third avoiding gap 625. The third avoiding gap 625 can avoid the area where the other side surface of the first avoiding slot 614 in the rotating shaft 611 is located. The second avoiding gap 624 and the third avoiding gap 625 enable the cooperation between the unlocking device 620 and the unlocking handle 610.
