Title:
A protection element and a battery pack
Document Type and Number:
Japanese Patent JP5952673
Kind Code:
B2
Abstract:
In order to obtain a protective element that can be easily made to fuse and that maintains current capacity during overcurrent protection, a protective element (10) is provided with: an insulating substrate (11); a heating element (14) that is layered on the insulating substrate (11) and that is covered by an insulating member (15); electrodes (12)(A1) and (12)(A2) that are formed on both ends of the insulating substrate (11); a heating element-drawing electrode (16) that is layered on the insulating member (15) so as to overlap with the heating element (14); and a fusible conductor (13), both ends of which are connected to the electrodes (12)(A1) and (12)(A2) and the central section of which is connected to the heating element-drawing electrode (16). The fusible conductor (13) comprises, for example, a thick section (13a) that has a round linear shape and measures 1.6 mmphi, and a thin section (13b) that is molded to be thinner than the thick section (13a) such that the thickness is substantially uniform at a position at which the section that faces the heating element (14) overlaps with the heating element (14). The thickness of the thin section (13b) may be, for example, 1/2 the thickness of the thick section (13a).
