Abstract
An electrical terminal pin is provided with a pin tip for insertion into a mating electrical female terminal, a hole in a printed circuit board or the like. The pin has an electrically conductive core plated with an electrically conductive layer. The pin tip is formed of a generally rounded pyramidal configuration defining four slightly curved convex sides joined at four edges converging at a pin end. Two opposite sides of the pin tip are non-plated. The other two opposite sides of the pin tip are plated with the conductive layer. Portions of the conductive plating layer overlap the edges of the pin tip in a smooth or rounded configuration to eliminate any sharpness thereof and to provide additional plated areas over the exposed core material. The pin tip is formed by a cutting and coining operation to form the configuration of the tip and to coin the overlapping portions of the conductive plating layer over the sharp edges of the pin tip.
