Abstract
An electrical contact pin has a fixing part to be fitted into a through hole of a circuit board for fixing without using any solder. The fixing part has a substantially rectangular cross section. A pair of alternating recesses are provided on opposite sides of said rectangular section. A pair of corners closer to said recesses extend beyond said sides to form a pair of projected corners. A process for manufacturing such an electrical contact pin is characterized by the step of pressing a metal work having a substantially rectangular cross section to form said fixing part in a pair of metal dies. A pair of projections are provided on the bottoms of said dies to form said recesses. A pair of opposite sides of said dies are arranged so that there may be small spaces between said pair of sides and the opposite sides of said work before pressed. A part of said bottom of each die is made deeper than the rest of said bottom so as to form said projected corner when said work is squeezed.
