ABSTRACT:
A simple and highly effective method and apparatus for field terminating flat power cable such as used in undercarpet wiring systems. Each conductor, with tightly bonded insulation, of a multi-conductor flat power cable is (at the point of installation in-situ) slotted or cut through with thin narrow slots which leave corresponding narrow rectangular openings through the insulation and conductor. Then a thin conductive device or terminal with corresponding ribs which easily though precisely fit into the slots, is placed in the slot openings, is secured in place on the cable by a suitable means, and the assembly then crimped or flattened together to give a pressure-tight high-conductivity, electrically stable termination only about twice as thick as the insulated conductor. The applicator tooling may be a simple punch and die, and a hammer or pliers. An insulating "bandage" is applied over the termination and bonded to the conductor insulation thereby giving a water-tight joint impervious to corrosion. The metal or steel top shield required by the National Electrical Code is similarly terminated in order to assure "ground" continuity.
