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 hole and it is then soldered to the base board around the periphery of the circular base board connecting hole with excellent connectability of the terminal to the base board.
