Abstract:
1. A current and temperature overload protection device comprising a brace made of a non-conductive material and having a flat top surface and a bottom surface; a thermal sensing contact made of a thermally conductive material and mounted on the flat top and bottom surfaces of the brace; an electrically conductive solder layer mounted on the thermal sensing contact at a position corresponding to the flat top surface of the brace; two ports made of an electrically conductive material, mounted on the flat top and bottom surfaces of the brace and separated from the thermal sensing contact; two resilient elements made of an electrically conductive material and each resilient element having two ends, wherein each resilient element is bent and spaced from the flat top surface of the brace and the ends of the resilient elements are mounted on and electrically connected to the solder layer and a respective one of the ports; and a cover made of non-conductive material, shaped corresponding to the brace and covering the flat top surface of the brace, wherein the brace is a printed circuit board, a plastic disc or a ceramic disc; and the thermal sensing contact is a band-like thermally conductible material that is mounted around the brace and contacts the top and bottom surfaces of the brace.
