Abstract

An electrical contact pair and a connector terminal pair that can reduce the amount of sliding wear in a contact portion. The electrical contact pair includes a first electrical contact, a second electrical contact, and a contact portion. The first electrical contact includes, above a first conductive base material, an Ag—Sn alloy layer, and a first AG layer that is laminated on a surface of the Ag—Sn alloy layer, and the first AG layer is exposed as the outermost surface. The second electrical contact includes a second AG layer above a second conductive base material, and the second AG layer is exposed as the outermost surface. The contact portion is obtained as a result of a surface of the first AG layer of the first electrical contact and a surface of the second AG layer of the second electrical contact being in contact with each other.

Dependent claims

An electrical contact pair comprising:

a first electrical contact that includes a first conductive base material, an Ag—Sn alloy layer that is laminated on a surface of the first conductive base material with a Ni layer and/or a Ni alloy layer interposed therebetween, and a first AG layer that is laminated on a surface of the Ag—Sn alloy layer, the first AG layer being exposed as an outermost surface;
a second electrical contact that includes a second conductive base material, and a second AG layer that is laminated on a surface of the second conductive base material with a Ni layer and/or a Ni alloy layer interposed therebetween, the second AG layer being exposed as an outermost surface;
and
a contact portion in which a surface of the first AG layer of the first electrical contact and a surface of the second AG layer of the second electrical contact are in contact with each other,
wherein contact pressure that is exerted on the contact portion is in a range from 100 N/mm2 to 500 N/mm2 inclusive.
