ABSTRACT:
A pierce-type contact element for use with a connector for a multi-conductor flat cable having a plurality of parallel insulated round wire conductors, each contact element having a circuit connecting terminal and a bifurcated part nested within the connector. The bifurcated part provides a pair of sharply pointed tines the opposed inner edges of which are spaced apart a distance less than the diameter of the wire conductor and act to slice through the conductor insulation to electrically engage opposite sides of the conductor wire. The tines are reversely bent to provide the same with parallel portions which are offset from one another along the longitudinal axis of the insulated conductor. The opposed inner edges of the tines are provided with sharply cornered cutting edges which respectively bite into and make contact with opposite sides of the conductor wire at two points spaced lengthwise of the wire. The parallel relatively offset portions of the tines of the contact element place the conductor under tension in the region of its connection to the contact element, the force of which tension serves to hold the contact element in secure electrical connection with the conductor.
