Abstract
The utility model relates to a triplex contact made of pure copper and silver alloy, which comprises a pure copper matrix (2), a silver alloy composite layer (1) and an offside composite layer (3). The pure copper matrix (2) consists of a cylindrical head part and a cylindrical pin part. The thickness of the cylindrical head part is larger than the thickness of the cylindrical pin part. The silver alloy composite layer (1) is compounded with one end of the pure copper matrix (2) with the cylindrical head part. The offside composite layer (3) is compounded with the other end of the pure copper matrix (2) with the cylindrical pin part. According to the technical scheme of the utility model, pure copper and finecrystalline silver are adopted to manufacture the triplex contact through the compounding and molding process, so that the triplex contact has the advantages of low production cost, large material strength, high welding resistance and electrical arc erosion resistance, high conductivity and low contact resistance. The triplex contact can be applied to low-voltage electrical appliances with the working current thereof smaller than 10A. Thus, the triplex contact can replace contacts made of pure silver to be applied to various occasions.
