At this time, the ring 2411 rotates synchronously with the connecting contact rod 2412. When the connecting contact rod 2412 rotates to a vertical state, the connecting contact rod 2412 releases the restriction on the matching contact 2213 that originally contacts the inner side of the connecting piece 221. At this time, the wiring system at the back end of the drawer 2 is automatically powered off. In the process of pulling out the drawer 2, the connecting terminal 232 is pulled out from between the plug-in slot plates 31; conversely, when the drawer 2 is pushed in, the connecting terminal 232 is first plugged into the plug-in slot plates 31, and then the rotary switch 24 is rotated back so that the connecting contact rod 2412 and the matching contact 2213 resume contact, and the power-on state is achieved. It should be noted here that the telescopic elastic wire 2212 is provided between the matching contact 2213 and the connecting seat 2211 to weaken the impact caused by the contact between the connecting contact rod 2412 and the matching contact 2213 and extend the service life.

The protective cover shell 231 here can be used as a gap compensation between the terminal female seat 3 and the terminal male seat 23, and meet the protection of the wiring terminal 232. When the wiring terminal 232 is plugged into the plug-in slot plate 31, the plug-in protrusion 2311 is precisely docked with the plug-in groove 30 to achieve a quick guiding effect and simplify the plug-in process. It is worth noting that the anti-slip strip 2312 installed on the inner side of the protective cover shell 231 can achieve the tightening of the two sides of the terminal female seat 3 after the plug-in protrusion 2311 and the plug-in groove 30 complete the guiding positioning, so as to prevent it from falling off at will and further enhance the stability of the wiring.

The outer surface sliding sleeve of 3211 is provided with a telescopic spring 2333, one end of the inner lining plate 233 is fixedly connected to the outer surface of the circular plate 2332, and the other end of the telescopic spring 2333 is fixedly connected to the inner surface of the sleeve 2331; the end of the sleeve 2331 away from the terminal male seat 23 is provided with a clamping member, the clamping member includes an annular plate 2334, the annular plate 2334 is fixedly installed at one end of the sleeve 2331, the inner wall of the annular plate 2334 is threadedly connected with a screw 23341, the inner end of the screw 23341 is rotatably connected with a wire clamping piece 23342, the outer surface of the wire clamping piece 23342 is movably abutted against the outer surface of the wire 2321, and the outer surface of the screw 23341 is movably connected to the inner wall of the annular sleeve 23211; In this embodiment, an anti-dropping piece is added to the inner side of the inner lining plate 233. When the drawer 2 is pulled outward, the terminal block 232 is detached from the plug-in slot plate 31. During this process, the wire 2321 is fixed by the clamping piece. Due to the flexibility of the wire 2321, when the wire 2321 is pulled by an external force, the circular plate 2332 drives the telescopic spring 2333 to be compressed. The elastic deformation of the telescopic spring 2333 can reduce the pulling force, thereby reducing the possibility of the pulling force directly acting on the connection point between the wire 2321 and the terminal block 232, thereby reducing the possibility of the connection point falling off or accidentally breaking. This further extends the electrical connection performance of the GCS outlet cabinet and the service life of its internal components.

[0026] In actual use, first, the terminal socket 3 is installed on the back plate 12 through the assembly mechanism 33, and the back plate 12 is adapted to correspond to the wiring plug-in mechanism set at the rear end of the drawer 2. Before the drawer 2 is pulled out, the rotary switch 24 is rotated, and the force rod 241 is rotated counterclockwise. At this time, the ring 2411 and the connecting contact rod 2412 rotate synchronously. When the connecting contact rod 2412 is in a vertical state, the connecting contact rod 2412 is separated from the matching contact 2213 that abuts against the inner side of the connecting piece 221 on one side. At this time, the wiring system at the back end of the drawer 2 is automatically powered off. In the process of pulling out the drawer 2, the wiring terminal 232 is pulled out from between the plug-in slot plate 31. At this time, the drawer 2 is powered off before it is pulled out; and when the drawer 2 is pushed in , the wiring system always remains in a power-off state; after the drawer 2 is pushed in, the connection between the wiring terminal 232 and the plug-in slot plate 31 is first completed, and after the connection is tightly fitted, the rotary switch 24 is rotated to make the connection contact rod 2412 in an initial horizontal state, and the connection contact rod 2412 contacts the matching contact 2213 to achieve a power-on state. In addition, a protective cover shell 231 is installed on the outside of the terminal male seat 23. The protective cover shell 231 serves as a gap compensation between the terminal female seat 3 and the terminal male seat 23 to meet the protection of the wiring terminal 232. When the wiring terminal 232 is plugged into the plug-in slot plate 31, the plug-in protrusion 2311 is accurately docked with the plug-in groove 30 to achieve a quick guiding effect.
