Abstract

A spring tension fuse clip is disclosed having a wire wrap leg formed integrally with the spring clip. The clip is formed from a single piece of material having a gauge heavy enough to satisfy the wire wrap terminal requirement while at the same time satisfying the spring tension fuse clip requirement. This result is achieved by coining the clip only at certain bends to reduce the spring tension to the desired amount. The clip is mounted to a flat surface by a locking tab on the wire wrap leg.

Claims

1. A spring tension fuse clip having a wire wrap leg formed integrally with the spring clip and having a U shape adapted for mating with and applying spring tension to one electrical terminal of an inserted fuse, said clip being formed from a single piece of electrically conductive material having a first gauge,

said U shape having two side portions and a lower portion, said side portions bent upward from said lower portion, wherein the material only within the bends formed between said side portions and said lower portion of said U is reduced in gauge so as to reduce the spring tension of said clip against an inserted fuse.

2. The invention set forth in claim 1 wherein said first gauge is thick enough to form a wire wrap leg having a diagonal cross-sectional area greater than 0.059 but not to exceed 0.073.

3. The invention set forth in claim 1 wherein said fuse clip has a second leg formed integrally with the fuse spring clip, said wire wrap leg and said second leg having formed thereon locking tabs.
