Title:
PROTECTIVE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/167069
Kind Code:
A1
Abstract:
This protective element (1A) comprises: an insulation substrate (2); a heat-generating body (3) disposed on one surface or the other surface of the insulation substrate (2); a first electrode (4) and a second electrode (5) disposed on the other surface of the insulation substrate (2); an extraction electrode (6) disposed between the first electrode (4) and the second electrode (5), the extraction electrode (6) being electrically connected to one end of the heat-generating body (3); a third electrode (7a) electrically connected to the other end of the heat-generating body (3); and a fusible conductor (9) disposed on the surfaces of the first electrode (4), the second electrode (5), and the extraction electrode (6), the fusible conductor (9) electrically connecting the first electrode (4) and the extraction electrode (6), and also electrically connecting the second electrode (5) and the extraction electrode (6). The surface area (S3) of the fusible conductor (9) disposed on the surface of the extraction electrode (6) is less than the surface area (S1) of the fusible conductor (9) disposed on the surface of the first electrode (4) and the surface area (S2) of the fusible conductor (9) disposed on the surface of the second electrode (5).
