PROTECTIVE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/088308
Kind Code:
A1
Abstract:
Provided is a protective element wherein a heat-generating body and a through-hole are disposed with an appropriate distance therebetween, thereby suppressing the occurrence of a crack in an insulating base board. The invention comprises: an insulating base board (10); a heat-generating body (14) formed between a pair of facing lateral edges (10c, 10d) of the insulating base board (10); a first heat-generating body electrode (18) provided on one lateral edge (10c) side of the pair of lateral edges (10c, 10d) of the insulating base board (10), electrically connected to the heat-generating body (14), and having a hole portion (25) formed therein; a second heat-generating body electrode (19) provided on the other lateral edge (10d) side of the pair of lateral edges (10c, 10d), and electrically connected to the heat-generating body (14); and a fusible conductor (13) which melts due to the heat generated by the heat-generating body (14)thereby cutting off the current path. The center (C1) of the heat-generating body (14) is offset from a position (C2) midway between the pair of lateral edges (10c, 10d) toward the other lateral edge (10d) side of the insulating base board (10).
