US 7,679,484 B2 · Fusible link unit

Abstract

A fusible link unit includes a housing and two fuse circuit bodies overlapped with each other and received in the housing in a thickness direction of the housing. A coupling plate and terminals connected to each other via fuse elements integrally forms the fuse circuit body. An opening is formed on an outer wall of the housing. The housing includes a cover made of transparent material and having a U-shaped section for covering the opening. The cover integrally includes a projection projecting to an inside of the housing on a sidewall of the cover. The projection includes a reflecting wall sloping on the sidewall in a thickness direction of the housing 7.

Claims7

Dependent claims

A fusible link unit comprising:

two fuse circuit bodies, each having a plurality of terminals connected to a coupling plate via fuse elements;
a housing having an opening at an outer wall and receiving the fuse circuit bodies and a transparent cover over the opening, the two fuse circuit bodies being overlapped with each other in a thickness direction of the housing;
and
a reflecting wall disposed in the housing arranged to reflect light transmitted from the opening through the transparent cover into the housing toward the fuse elements, and reflect heat emission caused by excessive current through the fuse elements so the temperature of the fuse circuit bodies is prevented from increasing.
