Abstract
A plurality of terminals each serving to fixedly mounting a connector housing on a printed circuit base board are successively produced by punching a single metallic plate of which opposite surface are coated with plated layers by actuating a press machine. Each terminal includes an electrical contact portion adapted to come in electrical contact with an opponent terminal at one end part, a fixing portion for fixedly securing the terminal to a connector housing at the intermediate part, and a base board connecting portion at other end part thereof. Each of the electrical connecting portion and the base board connecting portion has a rectangular sectional shape while the plated layers are kept alive thereon as they are. The base board connecting portion is plastically deformed to a cylindrical base board connecting portion having a circular sectional shape in the hollow space between a pair of press-forming die halves by actuating a press machine, causing the plated layer to extend around the substantially whole periphery of the cylindrical base board connecting portion. Subsequently, the cylindrical base board connecting portion is inserted through a circular base board connecting …
