Extra-soft tin-coated copper strip

Abstract

The invention discloses an extra-soft tin-coated copper strip. The extra-soft tin-coated copper strip comprises a soft winding copper strip; the outer surface of the copper strip is coated with a layer of tin-coated layer; the copper strip and the tin-coated layer are wound around the outer surface of a fixed shaft; two cylindrical side plates are welded at the two ends of the fixed shaft; the twoside plates and the side walls of baffles are clamped and connected; a protective cover is welded at the top ends of the baffles; and a rectangular supporting plate is fixed at the bottom ends of thebaffles. The outer surface of the extra-soft tin-coated copper strip provided by the invention is coated with the tin-coated layer, so that conductivity of the copper strip can be improved, high corrosion resistance is achieved, and copper strip deformation and failure caused by surface oxidization also can be avoided; and the fixed shaft and the side plates are in a fixed integrated body, and the copper strip is wound around the fixed shaft, so that the copper strip and the tin-coated layer on the surface can be protected from external pollution, thereby facilitating copper strip storage andprolonging the service life of the copper strip.

Description

technical field [0001] The invention relates to a copper strip, in particular to a supersoft tin-coated copper strip, which belongs to the technical field of metal equipment application. Background technique [0002] Copper strip is a kind of metal component. Copper strip is mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, and connectors. Its main function is to conduct electricity and heat. It is also a corrosion-resistant Components, switches, washers, gaskets and many other workpiece parts. Because the function of copper strip is clear, the effect is remarkable, and the benefits brought by work are high, so copper strip, as an important metal product, is widely used in various fields of our daily life. [0003] However, the copper strip currently used in the field of mechanical products still has some shortcomings. For example, many copper strips currently available on the market, as a conductive product, have an unsatis...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a supersoft tin-coated copper strip, which has good electrical conductivity, is not easily oxidized and denatured by air, is not easily corroded by strong acids and strong alkalis, and has the advantages of high service life. It is found that the current copper strips on the market have unsatisfactory electrical conductivity, are easy to corrode, easy to accumulate dust, and have high cost problems.
