[0022] Specifically, the multifunctional self-locking structure 4 also includes a placement groove 409, a connection block 410, a connection ring 411, a waterproof ring 412, a locking nut 413 and an insulating layer 414. The placement groove 409 is arranged on the right side of the inlet hole 401, the connection block 410 is arranged inside the placement groove 409, the connection ring 411 is arranged on the outside of the connection block 410, the waterproof ring 412 is arranged on the inside of the connection ring 411, the locking nut 413 is arranged on the outside of the connection ring 411, and the inner side of the locking nut 413 is connected to the insulating layer 414. 14. Pass the cables to be connected to the wire entry hole through the connecting block 410 and the connecting ring 411. The waterproof ring 412 is put on the inner ring of the connecting ring 411 to provide waterproof protection for the cables. Rotate the locking nut 413 to connect the locking nut 413 with the connecting ring 411. The setting of the connecting block 410, the connecting ring 411, the waterproof ring 412 and the locking nut 413 protects the cables and prevents the cables near the connector from being worn due to long-term bending, resulting in unstable contact with the wire entry hole and affecting the use of the switch cabinet.

[0023] Specifically, the locking piece 402 is connected to the fixing column 407 by a slot, the locking piece 402 and the limiting block 403 are arranged in a one-to-one correspondence, and the locking piece 402 connected to the slot of the fixing column 407 rotates with the displacement of the limiting block 403.

[0024] Specifically, the spring 406 and the paddle 405 are connected by adhesion, and the spring 406 and the bottom plate 408 are connected by bolts. After the paddle 405 is used, the spring 406 at the lower side of the paddle 405 drives the paddle 405 to return to its original position.

[0025] Specifically, the locking nut 413 and the connecting ring 411 are threadedly connected, the sizes of the locking nut 413 and the connecting ring 411 match, and the locking nut 413 is rotated to connect the locking nut 413 and the connecting ring 411.

[0026] Specifically, the waterproof ring 412 is connected to the connecting ring 411 by a slot, the outer diameter of the waterproof ring 412 matches the inner diameter of the connecting ring 411, and the waterproof ring 412 is sleeved on the inner ring of the connecting ring 411 to provide waterproof protection for the cable.

[0027] Specifically, the insulating layer 414 and the locking nut 413 are adhesively connected, and the outer diameter of the insulating layer 414 is the same as the inner diameter of the locking nut 413. The insulating layer 414 prevents the cable from being damaged and leaking electricity, which would affect the safety of the staff.

[0028] Working principle: First, when it is necessary to use the inlet hole of the switch cabinet with a self-locking structure, the cable to be connected to the inlet hole is passed through the connection block 410 and the inside of the connection ring 411, and the waterproof ring 412 is sleeved on the inner ring of the connection ring 411 to provide waterproof protection for the cable. The locking nut 413 is rotated to connect the locking nut 413 with the connection ring 411. The connection block 410, the connection ring 411, the waterproof ring 412 and the locking nut 413 are arranged to protect the cable and prevent the cable near the connector from being worn due to long-term bending, resulting in unstable contact with the inlet hole and affecting the use of the switch cabinet.

[0029] When connecting the connector to the switch cabinet, the paddle 405 is toggled to drive the movable plate 404 to rotate. The holes on the surface of the movable plate 404 move outside the fixed column 407. At the same time, the fixed column 407 limits the movable plate 404. The locking piece 402 connected to the slot of the fixed column 407 rotates with the displacement of the limit block 403, so that the incoming line hole 401 leaks out. The staff inserts the connector into the incoming line hole 401, and then releases the paddle 405. The spring 406 on the lower side of the paddle 405 drives the paddle 405 to reset, and the three sets of locking pieces 402 rotate to fix the connector. When unplugging, the staff also needs to repeat this operation to ensure that the plug can be safely unplugged. The setting of the locking piece 402 enables this design to ensure that the connector is firmly locked when inserted to prevent potential dangers caused by misoperation.
