ABSTRACT:
Contact pin for fastening in a perforation, particularly for pressing into lated-through holes in a printed circuit board, with a fastening section exhibiting an overwidth and a doubly symmetrical cross-section and exhibiting two mutually mobile lateral parts mutually distanced by two mutually diametrally opposite grooves extending in the longitudinal direction of the pin, while the lateral parts exhibit on their outsides a curvature which corresponds to the curvature of the cross-section of the perforation, particularly to the curvature of the printed circuit board holes provided to receive the pin, wherein the outsides of the lateral parts which come into contact with the inside of the printed circuit board holes together exhibit a circumferential extension between 70% and 90% of the circumferential extension of the inside of the printed circuit board hole and method for producing a contact pin whereby wire, preferably square wire, is drawn off from a wire coil and deformation thereof to overwidth with development of the curvature and of a contact circumferential extension of 70% to 90% of the circumferential extension of the insides of the printed circuit board hole is achieved in continuous sequence in conformity with the longitudinal dimensions of a contact pin.
