Abstract
The utility model discloses a structure of a copper twisted wire, and the structure comprises four copper-cored wires and three steel-cored wires. A silver plating layer is disposed outside each of the copper-cored wires, which are formed by drawing stainless steels. A nickel plating layer is disposed outside each of the steel-cored wires, and a silver plating layer is disposed outside each of the nickel plating layers. The four copper-cored wires and two of the steel-cored wires are arranged at intervals, and the remaining steel-cored wire is disposed in the middle of the four copper-cored wires and two of the steel-cored wires. The diameter of the copper-cored wire is 0.05mm-0.055mm or 0.07mm-0.075mm, and the diameter of the steel-cored wire is 0.05mm-0.055mm or 0.07mm-0.075mm. The structure has good conductivity, high tensile strength, and low cost. According to the utility model, three steel-cored wires are used for replacing a plurality of copper-cored wires, and the conductivity of the three steel-cored wires is equal to the conductivity of all copper-cored wires, but the mechanical property of the three steel-cored wires is better than that of all copper-cored wires.
