Title:
PROTECTIVE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/107631
Kind Code:
A1
Abstract:
In the present invention, the rated capacity of a fusible conductor is raised while enabling a rapid blow-out of the fusible conductor and increasing the amount of melted conductor allowed to be retained. The protective element is provided with: an insulation substrate (11); a first heating body (14) layered over the insulation substrate (11); an insulation member (15) covering the first heating body (14); first and second electrodes (12) layered over the insulation substrate (11); a heating body drawing electrode (16) layered over the insulation member (15) so as to overlap with the first heating body (14) and electrically connected to the first heating body (14) in the current path between the first and second electrodes (12); a fusible conductor (13) layered throughout from the heating body drawing electrode (16) to the first and second electrodes (12, 12) and blown out by heat so as to interrupt the current path between the first electrode (12) and the second electrode (12); and a cover member (19). A second heating body (25) is provided above the fusible conductor (13).
