More Information
Summary:The utility model provides an electrical connector belonging to the technical field of electrical contact elements, which comprises an electrical connector substrate. A metal film and a metal composite conducting layer are sequentially deposited on the electrical connector substrate. The metal film functions as a connecting layer of the electrical connector substrate and the metal composite connecting layer. The metal composite connecting layer is in the form of a carbon chromium film. According to the technical scheme of the utility model, the above surface-modified electrical connector has the composite performances of electricity conduction, corrosion resistance, abrasion resistance, water repellence and the like. The contact resistance of the electrical connector is smaller than or equal to 15 M omega*cm^2 under a pressing force of 0.8 Mpa, and the standard salt resistance of the electrical connector lasts over 270 hours or more during test. The surface microhardness Hv of the electrical connector is larg
