Plated material and method of manufacturing the same, terminal member for connector, and connector

摘要

A plated material reduces insertion and withdrawal forces when used in a connector. A terminal member for a connector and a connector therewith are also provided. The plated material comprises a substrate 3 made of Cu or a Cu alloy and a metal plating layer 6 formed on the surface of the substrate 3 . A soft region 6 A spreading in a network-shape and a hard region 6 B surrounded by the network of the soft region 6 A coexists in the metal plating layer 6 . The soft region 6 A has a Vickers hardness of 20 to 250, while the hard region 6 B has a Vickers hardness of 60 to 700, which is at least 30 higher than that of the soft region 6 A. An average size of the network of the soft region 6 A is from 5 to 500 mum.
