Title:
PROTECTIVE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/107632
Kind Code:
A1
Abstract:
In the present invention, the cross section of a fusible conductor is increased to raise the rating of the protective element while maintaining the insulation capability thereof. The protective element is provided with: an insulation substrate (11); a heating body (14) layered over the insulation substrate (11); an insulation member (15) covering the heating body (14); first and second electrodes (12) layered over the insulation substrate (11) whereon the insulation member (15) has been layered; a heating body drawing electrode (16) layered over the insulation member (15) so as to overlap with the heating body (14) and electrically connected to the heating body (14) in a current path between the first and second electrodes (12); and a fusible conductor (13) layered throughout from the heating body drawing electrode (16) to the first and second electrodes (12) and blown out by heat so as to interrupt the current path between the first electrode (12) and the second electrode (12). An in-flow portion (40) where the molten fusible conductor (13) flows into is provided under a blow-out portion (13a) of the fusible conductor (13).
