ABSTRACT:
Multi-pin male and female contact bars with composite contact posts having U-shaped upper contact post portions with two spaced tines and a transverse web portion to which is butt-welded a pin with an enlarged attachment head. The tines serve as spring tines of female contact members, or as cable-penetrating contact blades of male contact members, the associated butt-welded pins being solder pins for connection to a printed circuit board or male plug pins, respectively. The upper contact post portions are produced as die-cut segments of a sheet metal strip which remain connected to a carrier strip, until inserted into the contact post housing of the contact bar and severed from the carrier strip by a break-away movement.
