THERMAL SAFETY PLUG FOR AN ELECTRIC APPLIANCE

摘要

A thermal detection plug for use with an electrical apparatus is provided. The thermal detection plug includes: a housing, a thermal cut-off, contact prongs, and supporting structures to effectively interrupt the flow of electrical power at the point of interface of between the power cord of an appliance and power receptacle. The thermal detection plug interrupts power based on a temperature detected at the interface point.

主权项

1. A thermal detection plug for use with a power supply cord comprising a first and second conductor, wherein a first end of said first and second conductors attach to an electrical appliance; the thermal detection plug comprising:
a housing, wherein a second end of said first and second conductors attach to and enter said housing; a first contact prong at least partially disposed within said housing and protruding from said housing and electrically connected to said first conductor of said power supply cord; a second contact prong at least partially disposed within said housing and protruding from said housing and electrically connected to said second conductor of said power supply cord; a thermal cut off (TCO) disposed within said housing and in connected electrical series between said first contact prong and said first conductor; and an electrical current path capable of carrying an electric load through said first contact prong, said TCO, and said first conductor; wherein said TCO opens said connected electrical series between said first contact prong and said first conductor thereby disrupting said electrical current path in response to a temperature rise above a pre-determined temperature limit of one or more of said first contact prong, said second contact prong, said first conductor, said second conductor, and said housing.
