Title:
PROTECTION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/163730
Kind Code:
A1
Abstract:
Provided is a protection element which exhibits excellent fast fusing properties by preventing heat diffusion by means of efficient heat transfer from a heating element to a fuse element.
A fuse element 1 is provided with: an insulating substrate 2; a first front surface electrode 3 and a second front surface electrode 4, which are formed on a front surface 2a of the insulating substrate 2 so as to face each other; 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 front surface electrode 3, the second front surface 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 front surface electrode 3 and the second front surface electrode 4; a first back surface electrode 3a and a second back surface electrode 4a, which are formed on a back surface 2b of the insulating substrate 2; and a first lateral surface conducting part 3b and a second lateral surface conducting part 4b, which are formed on lateral surfaces 2c, 2d, 2e of the insulating substrate 2 and respectively connect the first front surface electrode 3 and the second front surface electrode 4 with each other and the first back surface electrode 3a and the second back surface electrode 4a with each other, while constituting all current paths which respectively connect the first front surface electrode 3 and the second front surface electrode 4 with each other and the first back surface electrode 3a and the second back surface electrode 4a with each other between the front surface 2a and the back surface 2b of the insulating substrate 2.
