Abstract:
1. A safety plug, comprising: a housing, having a first surface, a second surface and a third surface, said first surface and said second surface formed oppositely, said third surface formed perpendicular to said first surface and said second surface, a groove formed between said first surface and said second surface, a first tank, a second tank and a third tank formed respectively from the middle of said housing toward said first surface, said second surface and said third surface; a first metal blade, being disposed in said groove, one extremity of said first metal blade extending from said first surface thus forming an insertion part and the other extremity of said first metal blade extending from said second surface thus forming a first conductor; a second metal blade, being disposed in said first tank, one extremity of said second metal blade extending from said first surface thus forming an insertion part and the other extremity of said second metal blade forming a depression with two holes perpendicular to said insertion part, one hole using for fixing said second metal blade onto said housing by a rivet and the other hole using for fixing a contactor; a conducting device, being disposed in said second tank, one extremity of said conducting device forming a contacting part and the other part of said conducting device extending from said second surface forming a second conductor; a bimetallic strip, one extremity of said bimetallic strip being disposed above said contactor and the other extremity of said bimetallic strip being disposed onto said conducting device through the holes of said bimetallic strip and said contacting part by said rivet thus said bimetallic strip being fixed on the vertical holes of said second tank fastening on said housing; an isolating-equipment, being disposed in said third tank, one side of said isolating-equipment forming an insolating-sheet and the other side of said isolating-equipment extruding from said third surface thus forming a controller, said isolating-equipment forming a concave underneath; an elastomer, being disposed in said concave, the extremities of the elastomer leaning against on the inner side of said third tank and said concave; a cover, covering said housing; and an isolator covers said first conductor and said second conductor to envelope the space for said safety plug and an outer wire electrified.
