Description

Technical Field

[0001] The utility model relates to the technical field of silver-plated copper wires, in particular to a corrosion-resistant and environment-friendly silver-plated copper wire. Background Art

[0002] Wires refer to conductors that conduct electric current. They can conduct electric current effectively. Copper wires have good electrical and thermal conductivity, so they are widely used in the manufacture of wires. Silver-plated copper wires are made by concentrically plating a silver layer on a copper core. They combine the characteristics of two metals, have good electrical conductivity, and a bright and shiny surface. They also have high electrical conductivity, high heat resistance, and high temperature resistance. Therefore, they are widely used in non-ferrous wires, high-temperature cables, and aerospace cables.

[0003] The existing publication number CN207052314U discloses an environmentally friendly silver-plated copper wire structure with an anti-corrosion layer. An anti-corrosion layer is extruded between the inner insulating layer and the outer insulating layer, which improves the anti-corrosion performance of the silver-plated copper wire, thereby improving the service life of the product. The copper core is composed of multiple copper wires that are spirally wound together, which effectively improves the tensile strength of the copper core and the strength of the structure. The anti-corrosion layer is wrapped with a mesh shielding layer woven from round copper wires, which can prevent the internal copper core from being affected by external electromagnetic signals and improve the tensile strength of the entire wire body. The outer periphery of the copper core is provided with an insulating layer composed of an inner insulating layer and an outer insulating layer, which has a better insulation effect. Although the existing technology has a corrosion-resistant effect, the compressive effect is poor. For this reason, we propose a corrosion-resistant and environmentally friendly silver-plated copper wire. Utility Model Content
