ABSTRACT:
An electrical connector assembly in the form of a cable tap for use with a flat cable having wires of different sizes includes insulation penetrating terminals having sharp points on opposite sides of an insulation displacement slot. These sharp points are spaced apart and configured to reduce the tendency of the slots to diverge prior to engagement with the wires. Each slotted plate has inner and outer sloping edges with a slope of the inner edge relative to the center line of the slot being less than the slope of the outer knife edge so as to reduce the resultant force tending open the slot prior to engagement of the terminals with the wires. Additonally, the sharp points of a given terminal are spaced apart a lateral distance of from 1 to 1.5 times the diameter of the wire to be terminated therebetween. The terminals are positioned within the housing which is matable to a clamp having cylindrical grooves adapted to closely fit the curved outer cylindrical crest surrounding the ground wires in the cable. Terminals are insertable through apertures in a cable clamp penetrating the insulation and intersecting the individual wires.
