ABSTRACT:
A connector for joining a tap conductor to a run conductor of an underground cable system without removing the insulation from the run conductor. The connector includes a body of conductive material adapted to be connected to a tap conductor and having a piercing member for passage through the insulation of a run conductor. A clamp is provided to couple the piercing member to the run conductor. The clamp is adjustable for bringing the piercing member into tight interengagement with the run conductor and then supplying sufficient force to direct it through the insulation of the run conductor and into electrical communication with the interior thereof. The piercing member has a hollow cup-shaped configuration to minimize the force required to penetrate the insulation, provide maximum contact area for current transfer with low unit pressure on the conductor strands and small sealing area.
