ABSTRACT:
The invention features an insulative contact locking device for an electric range. When the heating coils of the range are caused to experience many heat cycles, the constant expansion end contraction of the heating terminals often causes a loosening of the power contacts. The invention comprises a pair of spring-biased contacts that positively hold the terminal ends in secure mechanical and electrical contact with the power wires.
