[0007] Preferably, the auxiliary mechanism comprises: A anti-dropping assembly is rotatably connected to the inner wall of the shell through a limiting piece. The rotating part comprises a sliding groove two formed in the inner wall of the shell, and the inner wall of the sliding groove two is rotationally connected with a limiting block four; The dustproof assembly is rotationally connected with the side wall of the connecting assembly through the protective piece. The protective piece comprises a baffle rotationally connected with the side wall.

[0008] Preferably, the connecting assembly comprises an interface fixedly connected with the side wall of the shell, and the inner wall of the interface is slidingly connected with a connector.

[0009] Preferably, the connecting assembly further comprises a cable fixedly connected with the side wall of the connector, the side wall of the cable is slidingly connected with the side wall of the limiting block one, the inner wall of the shell is formed with a clamping groove, the side wall of the connector is slidingly connected with the side wall of the clamping groove, and the side wall of the connector is fixedly connected with an elastic block.

[0013] A use method of an interface connecting mechanism of an optical transceiver, comprising the following steps: S1: fixing an optical fiber: first, fix the optical fiber cable through the L-shaped slot on the limiting block one, and then connect the connector into the interface after fixing; S2: connecting the clamping groove: the bottom elastic block of the connector is inserted into the clamping groove.

[0014] The present application has the following beneficial effects: (1) The present application aims at the problem that the connection between the joint and the interface and the soldering point between the interface and the circuit board are loose due to the pulling and shaking of the cable. When the device is disturbed by external force and the gravity of the cable itself, the cable will be pulled or pressed in all directions. At this time, because the diameter of the cable is slightly larger than the inner diameter of the L-shaped slot, there is a certain extrusion between the outer skin of the cable and the inner wall of the L-shaped slot. Limiting block two and limiting block three can prevent the cable from sliding out after being pulled after entering the L-shaped slot. At this time, the pulling force or extrusion force of the cable in all directions can be converted into the pressure and friction between the side wall of the cable and the L-shaped slot on the limiting block one to a certain extent, which can effectively reduce the pulling force of the cable near the interface and the shaking of the joint and the interface and the soldering point between the interface and the circuit board.

[0015] (2) The present application utilizes the above-mentioned feature that the cable between the two limiting blocks one is in a state of stretching or extrusion. Since the limiting block one is fixedly connected with the side wall of the shell, when the cable between the limiting blocks one is stretched and compressed, the friction between the cable and the limiting block one on the front side will drive the limiting block one on the front side to slide at the inner wall of the sliding groove one, and a certain uniqueness will occur. At the same time, the contact point between the cable and the limiting block one will also change. Through each stretching and compression, the length of the cable between the limiting blocks one will change, and the contact point will also change, avoiding the extrusion of the cable skin at the same point for a long time.

[0016] (3) The present application utilizes the above-mentioned feature that the cable will be stretched. When the joint slides at the inner wall of the clamping groove, the limiting block four will be extruded into the clamping groove under the action of the spring to limit the joint and realize the limiting of the joint. When the joint is pulled out, the stretching sliding block one slides in the sliding groove two, the stretching limiting block four rotates to compress the spring, and the contact limiting between the spring and the elastic block is released, which is automatically reset to avoid the elastic attenuation of the elastic block during long-term use. When the cable is subjected to a large horizontal pulling force, the cable between the limiting blocks one is in a straight state and will continue to be stressed, which causes the joint and the interface to be loose or even fall off, affecting signal transmission.

[0017] (4) In the long-term use of the device, the joint in the interface will extrude the baffle to rotate at the inner wall of the interface, and finally slide at the side wall of the baffle to extend inward. Since some interfaces may not be used, the baffle will naturally droop under the action of gravity at this time to avoid dust or insects from entering the interface and affecting the use of the interface.

[0028] First, the fiber cable is fixed through the L-shaped slot on the limiting block one 212, after being fixed, the connector 113 is connected into the interface 112, the bottom elastic block 116 of the connector 113 is inserted into the clamping groove 115, when the device is interfered by external force and the gravity of the cable itself, the cable 114 will be subjected to pulling force or extrusion in all directions, at this time, because the diameter of the cable 114 is slightly larger than the inner diameter of the L-shaped slot, there is a certain extrusion between the outer skin of the cable 114 and the inner wall of the L-shaped slot, the limiting block two 221 and the limiting block three 222 can prevent the cable 114 from sliding out after being subjected to the pulling force after entering the L-shaped slot, at this time, the pulling force or extrusion force in all directions of the cable 114 can be converted into the pressure and friction force between the side wall of the cable 114 and the side wall of the L-shaped slot on the limiting block one 212 to a certain extent, so that the pulling force and shaking of the cable 114 close to the interface 112 can be effectively reduced, the connection between the connector 113 and the interface 112 is loosened, and the solder joint between the interface 112 and the circuit board is loosened.

[0029] The protection assembly (21) comprises a telescopic rod (214) arranged between the two limiting block ones (212), the side walls of the telescopic rod (214) are fixedly connected with the side walls of the limiting block one (212), the limiting block one (212) close to the connector (113) is fixedly connected with the inner wall of the sliding groove one (211), and the side wall of the roller (213) is slidably connected with the inner wall of the sliding groove one (211).

[0030] ​The limiting assembly (22) comprises a limiting block three (222) fixedly connected to the side wall of the limiting block one (212); The anti-dropping assembly (31) comprises a sliding groove two (311) formed in the inner wall of the shell (111), and the limiting block four (312) is rotationally connected to the inner wall of the sliding groove two (311).

[0031] The anti-dropping assembly (31) further comprises a spring (313) fixedly connected to the side wall of the limiting block four (312), and the other side wall of the spring (313) is fixedly connected to the inner wall of the sliding groove two (311), and the side wall of the limiting block four (312) is slidably connected to the side wall of the joint (113). The anti-dropping assembly (31) further comprises a sliding block one (314) rotationally connected to the side wall of the limiting block four (312), and the side wall of the sliding block one (314) is slidably connected to the inner wall of the sliding groove two (311).

[0032] Under the condition that the cable 114 between the limiting block one 212 is in a state of stretching or extrusion, since the limiting block one 212 is fixedly connected to the side wall of the shell 111, when the cable 114 between the limiting block one 212 is stretched and compressed, the friction between the cable 114 and the limiting block one 212 on the front side will drive the limiting block one 212 on the front side to slide in the inner wall of the sliding groove one 211, and a certain displacement occurs, and the contact point between the cable 114 and the limiting block one 212 will also change. Through each stretching and compression, the length of the cable 114 between the limiting block one 212 will change, and the contact point will also change, thereby avoiding that the cable 114 is worn out due to extrusion at the same point for a long time.

[0033] When the elastic block 116 slides in the inner wall of the clamping groove 115, the limiting block four 312 will be extruded into the clamping groove of the elastic block 116 under the action of the spring 313, and the elastic block 116 is limited, so as to limit the joint 113. When the joint 113 is pulled out, the sliding block one 314 is stretched and slides in the sliding groove two 311, the sliding block one 314 stretches the limiting block four 312 to rotate and compress the spring 313, so as to remove the contact limitation between the sliding block one 314 and the elastic block 116, and the elastic block 116 is automatically reset, thereby avoiding that the elastic block 116 is attenuated due to long-time use, and when the cable 114 is subjected to a large horizontal tension, the cable 114 between the limiting block one 212 is in a straight state and is continuously stressed, which causes the joint 113 and the interface 112 to be loose or even to be detached, and the signal transmission is affected.

[0034] In the long-term use of the device, the joint 113 in the interface 112 used will extrude the baffle 321 to rotate at the inner wall of the interface 112, and finally slide to extend inward at the side wall of the baffle 321. Since some interfaces 112 can not be used, the baffle 321 will naturally sag under the action of gravity, thereby avoiding dust or insects from entering the interface 112 to affect the use of the interface.

[0035] A method for using an interface connection mechanism of an optical transceiver, comprising the following steps: S1: fixing an optical fiber: first fix the optical fiber cable through the L-shaped slot on the limiting block one 212, and then connect the joint 113 into the interface 112 after fixing; S2: access the card slot: the bottom elastic block 116 of the joint 113 is inserted into the card slot 115.

[0036] A specific application of the embodiment is as follows: first fix the optical fiber cable through the L-shaped slot on the limiting block one 212, and then connect the joint 113 into the interface 112 after fixing, and insert the bottom elastic block 116 of the joint 113 into the card slot 115. When the device is disturbed by external force and the cable is affected by its own gravity, the cable 114 will be subjected to pulling force or extrusion in various directions. At this time, because the diameter of the cable 114 is slightly larger than the inner diameter of the L-shaped slot, there is a certain extrusion between the outer skin of the cable 114 and the inner wall of the L-shaped slot. The limiting block two 221 and the limiting block three 222 can prevent the cable 114 from sliding out after being subjected to the pulling force after entering the L-shaped slot. At this time, the pulling force or extrusion force in various directions that the cable 114 is subjected to can be converted into the pressure and friction between the side wall of the cable 114 and the side wall of the L-shaped slot on the limiting block one 212 to a certain extent, which can effectively reduce the pulling force and shaking of the cable 114 close to the interface 112, so as to prevent the connection between the joint 113 and the interface 112 from loosening and the solder joint between the interface 112 and the circuit board from loosening.

[0037] Under the condition that the cable 114 between the limiting block one 212 is in a state of stretching or extrusion, since the limiting block one 212 is fixedly connected with the side wall of the shell 111, when the cable 114 between the limiting block one 212 is stretched and compressed, the friction between the cable 114 and the limiting block one 212 on the front side will drive the limiting block one 212 on the front side to slide at the inner wall of the sliding groove one 211, and a certain displacement will occur. At the same time, the contact point between the cable 114 and the limiting block one 212 will also change. Through each stretching and compression, the length of the cable 114 between the limiting block one 212 will change, and the contact point will also change, thereby avoiding the extrusion of the cable 114 at the same point for a long time to cause the abrasion of the outer skin of the cable 114.

[0038] When the elastic block 116 slides at the inner wall of the clamping groove 115, the limiting block four 312 will be squeezed into the clamping groove of the elastic block 116 under the action of the spring 313, limiting the elastic block 116 to realize the limiting of the connector 113. When the connector 113 is pulled out, the slider one 314 is stretched to slide in the sliding groove two 311, the slider one 314 stretches the limiting block four 312 to rotate and compress the spring 313, so as to release the contact limiting between the elastic block 116, automatically reset, avoid the elastic attenuation of the elastic block 116 in the long-term use process, when the cable 114 is subjected to a larger horizontal tension, the cable 114 between the limiting block one 212 is in a straight state and will continue to be stressed, causing the connector 113 and the interface 112 to loosen or even fall off, affecting the signal transmission.

[0039] In the long-term use process of the device, the connector 113 in the interface 112 used will extrude the baffle 321 to rotate at the inner wall of the interface 112, and finally slide to extend inward at the side wall of the baffle 321. Since some interfaces 112 may not be used, the baffle 321 will naturally droop under the action of gravity at this time, avoiding dust or insects from entering the interface 112 to affect the use of the interface.
