[0014] The present invention provides a wiring structure for an electrical switch cabinet, which has the following beneficial effects:

[0015] (1) The wiring structure of the electrical switch cabinet is such that the terminal board cannot move downward due to the limit block. The terminal board cannot move downward to prevent the terminal board from over-tightening the connecting wire. By limiting the tightening force, it can be ensured that there is enough contact area between the terminal board and the connecting wire and it is not affected by excessive pressure, thereby ensuring stable current transmission. The protective frame can be used to shield the rotating part to prevent the rotating part from rotating under the action of external force and causing the connecting wire to loosen. The shielding of the protective frame can effectively prevent the rotating part from rotating, thereby preventing the connecting wire from loosening due to the rotation of the rotating part.

[0016] (2) The wiring structure of the electrical switch cabinet is such that the stabilizing frame moves downward to contact the curved plate and cooperates with the curved plate to protect the fixing point of the connecting wire. If the fixing point of the connecting wire is excessively bent, the insulation layer of the connecting wire will be damaged. The protection of the stabilizing frame and the curved plate can effectively avoid this situation, ensuring that the fixing point of the connecting wire is kept in the correct stress state. The arc block moves slowly downward to cause the L-shaped rod to move slowly downward, and the L-shaped rod moves slowly downward to cause the stabilizing frame to move slowly downward and contact the connecting wire. The slow movement of the stabilizing frame can effectively control the deformation of the fixing point of the connecting wire, preventing the connecting wire from being damaged by the sudden impact of the stabilizing frame, thereby improving the protection effect of the connecting wire.

[0017] (3) The wiring structure of the electrical switch cabinet detects whether the connecting wire has been firmly installed in the wiring slot. After the connecting wire has been firmly installed in the wiring slot, the power button is manually pressed, and the wiring block is energized by pressing the power button. By detecting that the connecting wire has been firmly installed in the wiring slot, the wiring block can be energized, thereby avoiding safety hazards such as electrical short circuits or poor contact caused by loose connecting wires, thereby greatly reducing the occurrence of electrical accidents and ensuring the safety of the electrical switch cabinet and personnel.

One end of the No. 1 spring is arranged on the inner wall of the terminal slot 2, and the other end is arranged on the surface of the terminal block 4. The terminal block 4 can be driven to reset by the No. 1 spring. A connecting hole 11 is opened on the top of the terminal block 1. The rotation of the rotating part 3 can be effectively prevented by the shielding of the protective frame 9, thereby preventing the connecting wire from loosening due to the rotation of the rotating part 3.

[0029] A No. 2 spring is arranged between the hollow block 5 and the limit block 6, and the No. 2 spring can drive the limit block 6 to reset.

The L-shaped rod 136 moves slowly downward, causing the stabilizing frame 133 to move slowly downward and contact the connecting line. When the connecting line is inspected and debugged, the protective frame 9 is pushed to move backward. The protective frame 9 moves backward and drives the linkage block 10 to move backward.
