Abstract
A fuse element is formed integrally from a conductive metal plate such that two narrow portions are formed side by side between a pair of electrical connection portions. The narrow portions each assume an arch shape and constitute a parallel conductive path. Arch-shaped convex portions are arranged so as to oppose to each other with a predetermined gap therebetween, thus constituting a fusing portion.
Claims10
A fuse element, comprising:
- a first narrow portion and a second narrow portion made of a conductive metal and having a fusible portion, the first and second narrow portions constituting a parallel conductive path;
- and
- a pair of electrical connection portions connected to said first and second narrow portions;
- wherein the fusible portions of each of the first and second narrow portions are curved in such a manner that convex portions of the fusible portions are arranged so as to approach and oppose each other with a predetermined gap therebetween;
- wherein the first and second narrow portions are extended in a single plane and are formed in an arch shape in the plane;
- and
- wherein the pair of connection terminals and the first and second narrow portions form a metal plate.

A fuse element, comprising:
- a pair of connection terminals generally extending in a first direction;
- a connecting portion interconnecting one end of said connection terminals, said connecting portion generally extending in a second direction perpendicular to said first direction;
- and
- an insulating housing partially accommodating said connecting portion and said connection terminals,
- wherein at least a portion of said connecting portion is unclosed;
- wherein said connecting portion includes a pair of electrical connection portions and a pair of opposing narrow portions interconnecting the electrical connection portions;
- and,
- wherein said opposing narrow portions include fusing portions curved toward each other to define convex portions with a predetermined gap therebetween.
