ABSTRACT:
A connector apparatus to couple an electrical cable of a low-voltage power supply to an electrically-resistive heater strip carrying a layer of thermoplastic adhesive. The connector includes an elongated housing having a projecting support leg and a clamp jaw at opposite ends of the housing to support the housing so as to extend in a downwardly-inclined manner. The walls of the housing form an open cavity which is adapted to receive a helical spring through which a cable extends from an end wall of the housing to a connector used to secure the end of the cable to a bus bar. The bus bar is guided for movement along the length of the housing. The bus bar is urged by the spring toward the clamp jaw to grip the edge of the electrically-resistive heater strip used to heat in situ the thermoplastic adhesive that forms carpet seaming tape.
