Abstract
A cable connector (82) including a thermal fuse (25) for use with a low voltage electrical system (1). The preferred connector (82) includes a pair of electrically and thermally conductive jumper elements (19,23) with a plurality of sharpened edges (30,33,64,67) for piercing the insulating jacket (32,35,73,74) surrounding the inner conductors (14,15,22,24) with which the jumpers (19,23) make electrical contact. The jumpers (19,23) include a plurality of conductor engaging slots (31,34,65,66,68,69) which mechanically grip the conductors. In operation, the quality of the electrical contact between the jumpers and the conductors is proportional to the amount of heat radiated at the junction between the terminals (26,27,62,63) and the conductors (14,15,22,24), the heat causing the thermal fuse (25) to break the electrical circuit when the sensed heat exceeds a predetermined threshold.
