ELECTRICAL CONTACT, CONNECTOR TERMINAL PAIR, AND CONNECTOR PAIR

WIPO Patent Application WO/2018/079253

A1

The present invention provides: an electrical contact which is capable of achieving a good balance between low coefficient of friction and low contact resistance even after sliding; and a connector terminal pair and a connector pair, each of which is provided with this electrical contact. An electrical contact that is composed of a first contact 10 and a second contact 20, which are capable of forming an electrical contact with each other. This electrical contact is configured such that: the first contact 10 comprises an alloy-containing layer 14 which has an alloy part 14a that is formed of an alloy containing tin and palladium and a tin part 14b that is formed of tin or an alloy which has a higher ratio of tin to palladium than the alloy part 14a, and wherein both the alloy part 14a and the tin part 14b are exposed in the outermost surface; and the second contact 20 comprises a dissimilar metal layer 22 in the outermost surface, said dissimilar metal layer 22 having a higher hardness than the alloy-containing layer 14, while being formed of a metal that contains neither tin nor palladium. According to the present invention, a connector terminal pair and a connector pair are configured to comprise this electrical contact.
