[0002] Cables are usually rope-like cables twisted together by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, and are used to connect circuits, electrical appliances, etc.

The utility model clamps the cable by arc support plate and arc pressure plate, then tightens the movable bolt, bends the wire core and inserts it into the mounting groove, and then rotates the threaded rod to drive the mounting seat to rotate, so that the mounting seat screws the two wire cores together through the mounting groove. In this way, the wire cores of the cable can be better docked, the operation is more convenient, and the operation of the staff's hands is avoided, thereby greatly reducing the staff's work intensity, improving work efficiency, and also greatly improving practicality;
