Description

Technical Field

[0001] This utility model relates to the technical field of copper connecting nails for cables, specifically a self-welding copper connecting nail for cables. Background Technology

[0002] Welding cable is also known as welding machine cable. Welding machine cable (YH cable) is officially called high-strength rubber-sheathed welding machine cable, commonly known as welding cable. It is a type of YC cable (general rubber-sheathed cable). Self-welding cables require connecting copper nails when connecting.

[0003] Currently available self-welding cable connectors have poor corrosion resistance and low strength. Long-term use can cause damage to the connectors due to external factors, affecting the cable connection and failing to meet usage requirements, thus shortening the lifespan of the connectors.

[0004] Therefore, it is necessary to provide a self-soldering cable connector to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or to imply in any way that the information constitutes prior art known to those skilled in the art.

[0012] Preferably, the outer surface of the passivation layer is adhered to the inner surface of the antioxidant layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the copper base layer has excellent thermal conductivity, ductility and corrosion resistance, which increases the corrosion resistance of the copper nail body. The outer surface layer can remain non-volatile and non-hygroscopic at room temperature, effectively resisting the corrosion of metal by damp heat, salt spray and toxic bacteria. It can protect the copper base layer from oxidation to a certain extent. The reinforcing layer has good toughness and can withstand certain impacts and vibrations, and has high fatigue strength.
