Circuit protection assembly

Abstract

A circuit protection assembly has a protection element having a positive temperature coefficient of resistance and consisting of a polymer-based conductive composite material layer tightly clamped and fixed between two metal electrodes and a copper clad laminate having a through hole in a middle thereof, wherein the protection element is provided in the through hole, the copper clad laminate serves as a substrate for the circuit protection assembly and has an adhesive layer on an upper surface and a lower surface thereof, so as to cover the protection element in a space formed by the copper clad laminate and the upper and the lower adhesive layers. The protection element having a positive temperature coefficient of resistance is electrically connected to a protected circuit via a conductive part.
