Abstract:
1. A temperature fuse protection device, comprising: two terminals, a hot melt metal, and an elastic connecting unit, wherein an attachment assembly for the two terminals is established in a circuit, and a spacing is maintained between free ends of the two terminals when no external force is imposed, and a through hole is formed in at least one free end of the two terminals for allowing the hot melt metal to pass through, and wherein the hot melt metal is strip-shaped, and having the characteristics of breaking when heated or under elevated temperature, and wherein the elastic connecting unit, comprising two connecting bars, is connecting the two terminals and making them electrically-connected, and at least one end of the two connecting bars formed with an open hole for passing through, and wherein when assembled, the hot melt metal of proper length is put through the open hole at the end of a first connecting bar of the two connecting bars and the through hole in the free end of a first terminal of the two terminals, and using a riveting method for impacting the hot melt metal, the two ends of the hot melt metal are enlarged, and are connecting a free end of a first terminal with a first connecting bar of a elastic connecting unit, and pressing a second connecting bar of the two connecting bars of the elastic connecting unit against the first connecting bar for achieving a tight fit and coupling together, both terminals forming an electrical connection, and the ends of both connecting bars of the elastic connecting unit abut upon each other to produce elasticity outward, wherein when no external force is imposed, each of the free ends of the two terminals are vertically overlapped with one another and separated by the spacing without touching each other.
