AI Technical Summary
Existing DC contactors rely on bolts for tightening when connecting wires, which is cumbersome and affects work efficiency.
The system employs an adjustment mechanism and an operating mechanism. By rotating the adjusting threaded block, the connecting plate is moved, which compresses the spring and adjusts the pressure of the plug pin. The operating mechanism then disengages the plug pin from the fixing ring, facilitating wire insertion and clamping.
It simplifies wiring operations, improves work efficiency, enhances adaptability to different wire specifications, and achieves a quick and labor-saving wiring process.
