Title:
VARISTOR DEVICE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2007042753
Kind Code:
A
Abstract:

To provide a varistor device which is economical enough to minimize the content of a low-melting-point metal in a temperature fuse, and which has high-performance varistor element separating function.

A pair of leading conductors 3 for separating varistor elements and an auxiliary spring material 4 are secured to both ends of one surface of an insulating exterior surface 14 of a two-element integrated three-port varistor element 2 with an adhesive agent 5. The leading conductor 3 is provided with a fixed conductor 3a to be secured by the adhesive agent 5, a current fuse 3b formed of one copper wire extending from the fixed conductor 3a, and a temperature fuse 3c. The temperature fuse 3c is joined with the power line side terminal L1 or L2 of the varistor element 2 by a low-melting-point metal 6. The spring material 4 is comprised of a fixed spring 4a to be secured by the adhesive agent 5 and a conductor energizing part 4b extended from the fixed spring 4a, and the conductor energizing part 4b biases the current fuse 3b of the leading conductor 3 in the orthogonal direction.
