With the development of welding technology, the market urgently needs a cable that can meet repeated bending, resist flexing, and can simultaneously provide the large current and various sensor signals required for welding. Welding gun cable came into being.

[0003] After searching, the welding gun cable with announcement number CN202422812U includes conductor, air inlet pipe, control wire, winding layer and sheath, and its characteristics are: a nylon air inlet pipe is set in the center of the cable, and 4 control wires are set on its periphery, and conductors are set alternately between every two control wires in the order of 2 and 3, totaling 8 conductors; the control wires and conductors are wrapped with nylon cloth winding layer, thermosetting cross-linked polyolefin elastomer sheath, high temperature resistant glass fiber and fine stainless steel braiding layer in turn. It has excellent weather resistance, wear resistance and oil resistance, can be produced in large lengths to meet the needs of long-distance welding, and can adapt to the working environment temperature of -45℃~60℃ for long-term safe use;

[0004] Based on the above patent, the control line and the conductor are wrapped with nylon cloth, thermosetting cross-linked polyolefin elastomer sheath, high temperature resistant glass fiber and fine stainless steel braid. It has excellent weather resistance, wear resistance and oil resistance, can be produced in large lengths, meets the needs of long-distance welding, and is suitable for long-term safe use in working environments with temperatures of -45°C to 60°C. However, when using a welding gun for welding, it is necessary to frequently change positions, so it is necessary to frequently pull, drag and twist the cable. Because the internal structure of the cable is relatively simple, it does not have the ability to resist dragging and twisting for a long time. Therefore, the cable in the prior art is prone to copper wire tearing and breaking during long-term use, which seriously affects the service life of the welding gun cable. Utility Model Content
