Title:
PROTECTION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/163766
Kind Code:
A1
Abstract:
Provided is a protection element which is suited to a large current, while being prevented from increase in the volume of a fuse element, and which has excellent fast fusing properties and excellent insulating properties after fusing.
A fuse element 1 is provided with: an insulating substrate 2; a first electrode 3 and a second electrode 4, which are provided on the insulating substrate 2; a heating element 5; a heating element lead-out electrode 6 which is electrically connected to the heating element 5; a fuse element 7 which is connected across the first electrode 3, the second electrode 4 and the heating element lead-out electrode 6, and which melts by means of heating by the heating element 5, thereby blocking the current path between the first electrode 3 and the second electrode 4; and an auxiliary conductor 8 which is electrically connected to the fuse element 7 so as to correspond to the region where the fuse element 7 and the heating element lead-out electrode 6 are superposed on each other. Consequently, some of the current flowing through the fuse element 7 is bypassed to the auxiliary conductor 8.
