AI Technical Summary
When connecting the grounding wires of the existing low-voltage distribution cabinets, the cable ties need to be buttted and tightened and cannot be quickly connected. The connecting rod lacks a limited mechanism to the ground, which is easy to disengage, affecting the circuit depolarization treatment.
A low-voltage distribution cabinet with protective function was designed, and the connecting wire was defined at the inner inner wall of the main body of the low-voltage distribution cabinet, and the connecting wire was easily disassembled by the coupling of the snap ring and the support ring. At the same time, the coordination between the trapezoidal ring and the defining ball is used to increase the friction between the connecting rod and the ground to prevent disengagement.
It realizes rapid fixing and convenient disassembly of the connecting wire, ensuring stable grounding of the electrical equipment, avoiding the problem of connecting rod disengagement, and thus ensuring effective depolarization of the electrical equipment.

At this time, the trapezoidal ring 811 pushes the limiting ball 812 outward and clamps the limiting ball 812 in the ground, thereby increasing the friction between the connecting rod 85 and the ground, thereby avoiding the easy pulling out of the connecting rod 85, thereby ensuring the grounding stability of the electrical equipment, and then ensuring that the electrical equipment is effectively depolarized through the connecting line 7. The sliding rod 814 is pushed upward by the spring 815, and the trapezoidal ring 811 is moved upward, thereby changing the contact point between the trapezoidal ring 811 and the limiting ball 812, and making the limiting ball 812 contact the larger diameter of the trapezoidal ring 811, so that the trapezoidal ring 811 pushes the limiting ball 812 to move outward.It can achieve the purpose of increasing the friction between the connecting rod 85 and the ground, and avoid the connecting rod 85 from being easily pulled out, thereby ensuring the grounding stability of the electrical equipment, and then ensuring that the electrical equipment is effectively depolarized through the connecting wire 7. At the same time, the connecting wire 7 is limited to the clamp ring 66 through the mounting ring 68, and the clamp ring 66 is limited to the inner wall of the low-voltage distribution cabinet body 1 through the supporting ring 63 and the docking block 64. At the same time, the connecting rod 85 is firmly inserted into the ground through the limiting ball 812, thereby ensuring the stable connection of the electrical equipment to the ground wire, and the connecting wire 7 can be arranged through the limiting mechanism 6, so that the connecting wire 7 is neatly arranged.
