[0031] When in use, the pressing piece 25 includes a pressing plate 251 arranged at the top and bottom of the sliding tube 23. One side of the pressing plate 251 passes through the sliding tube 23 and is fixedly connected to a fixing plate 252. The top and bottom of the sliding tube 23 are both provided with through grooves, which cooperate with the pressing plate 251.

[0032] Specifically, the pressing plate 251 is arranged at the top and bottom of the sliding tube 23. When the user presses the pressing plate 251, the fixing plate 252 can be driven to move through the connecting rod 255. The fixing plate 252 is fixedly connected to the pressing plate 251. The flexible pad 253 on one side can wrap and fix the cable, which is convenient for plugging and unplugging the cable and avoids damage to the cable during operation.

[0041] Specifically, the elastic part 151 provides buffering protection and tight abutment, the abutment plate 152 transmits elastic force, the anti-slip pad 153 increases friction, the slider 154 and the slide rod 155 guide and limit, and the support plate 156 supports the slide rod 155 and reinforces the structure, which together ensure the stability of the connector structure, stable signal transmission and long-term reliable operation.

[0042] Working principle of the present invention: S1. The connector body 11 is the core, responsible for realizing the electrical connection between the cable and the device. The shielding shell 12 is tightly wrapped around the surface of the connector body 11. Based on its good conductive performance, it effectively blocks the interference of external signals on internal signal transmission and realizes signal crosstalk prevention. The cover plate 13 is firmly installed on the top of the shielding shell 12 through the connector 14 (the buckle seat 141 and the buckle hook 142 are buckled with each other) to prevent dust and debris from entering the interior and protect the internal structure of the connector; S2. When it is necessary to plug or unplug the cable, the user holds the sliding tube 23, which is located in the slide groove 22 of the shielding extension tube 21 and can slide smoothly along the slide groove 22. The limit blocks 241 on both sides of the sliding tube 23 slide in the limit grooves 242 of the slide groove 22 to ensure that the sliding tube 23 moves within the specified range. While holding the sliding tube 23, the user presses the top and bottom pressure plates 251, and the pressure plates 251 drive the fixing plates 252 to move through the connecting rods 255. The flexible pads 253 on one side of the fixing plates 252 move accordingly and tightly wrap the cables to fix the cables. At this time, the user can complete the plug or unplug operation of the cables by applying force to the sliding tube 23 and moving the sliding tube 23 away from the connector body 11, thereby transferring the force application point from the cables to avoid directly pulling the cables, thereby ensuring the fixing and protection of the cables during the plug or unplug process. S3. When it is necessary to observe the connection between the cable and the connector, the user disengages the hook 142 from the buckle seat 141, thereby conveniently removing the cover 13 to check the internal connection. The contact part between the buckle seat 141 and the hook 142 is made of smooth material, which reduces the friction during buckling and makes the disassembly process smoother.
