Heat responsive power interrupting device

摘要

An electric device is provided as an interface between a permanent power source (e.g., an electric wall outlet) and an electrical appliance. The device operates to interrupt electrical power to the electrical appliance in response to an increase in temperature of either the power cord plug of the electrical appliance or the terminals of the permanent power source to a predetermined temperature. The electric device detachably couples to the electric power terminals of both the permanent power source and the electrical appliance and is sensitive to the temperature at the terminals. The device includes a thermostat which rests on a thermal barrier member in thermal communication with the terminals, and is responsive to heat generated at the terminals to interrupt electrical power from the permanent power source to the appliance.
