Abstract
A fuse clip assembly is disclosed for use with alarm type fuses. The assembly includes a forward spring tension clip, a rear spring tension clip and an alarm terminal. The rear clip is shaped to thrust the fuse forward while the forward clip is designed with a shoulder to position the fuse. The alarm terminal is positioned to catch an extended fuse alarm terminal and is shaped to securely capture the terminal to insure positive electrical contact for alarm purposes. An arrangement is disclosed which provides visual-only alarm indications.
Claims11
A fuse clip mounting board assembly for use with tubular alarm type fuses, said mounting board assembly having a load spring clip terminal, a line spring clip terminal, and an alarm terminal,
- said load spring clip terminal including means for applying spring tension to a rear terminal of an inserted fuse, said spring tension being applied both perpendicularly to the body of said fuse and longitudinally along the axis of said fuse body,
- said line spring clip terminal including means for applying spring tension to a front terminal of an inserted fuse, said spring tension being applied perpendicularly to the body of said fuse, said line spring clip terminal also including means for restricting the movement of said inserted fuse forward along said longitudinal axis, and
- said alarm terminal including means for retaining an alarm contact extended axially from a front end of said fuse.
The invention set forth in claim 3 wherein said alarm terminal retaining means further includes forming the areas around said slot in a concave manner with respect to a captured fuse alarm contact.
A fuse clip assembly comprising
- a mounting board having holes therein,
- first and second terminals, each having a wire wrap leg portion and a tubular fuse terminal clip portion for mating with tubular alarm type fuses,
- said mounting board having an edge thereof formed perpendicular to the plane of said board, said edge having shaped therein a slot,
- means, including the mating of said mounting board holes and locking tabs constructed on said wire wrap legs of said first and said second terminals, for securing said first and said second terminals in a line with said slot in a manner such that when a tubular alarm fuse is inserted in said first and said second terminals the visual alarm indicator located on the longitudinal axis of said fuse protrudes through said mounting board slot only when said visual alarm indicator is extended to the alarm position.
A fuse clip assembly comprising
- a mounting board having holes therein,
- first and second terminals, each having a wire wrap leg portion and a tubular fuse terminal clip portion for mating with tubular alarm type fuses, said terminals each being of unitary construction,
- an alarm terminal having a wire leg portion and a fuse alarm contact capture portion, p1 means, including the mating of said mounting board holes and locking tabs constructed on said wire wrap legs of said first, second and alarm terminals, for securing said first, second and alarm terminals in a line such that when a tubular alarm fuse is inserted in said first and said second terminals the fuse alarm contact located on the longitudinal axis of said fuse contacts said alarm terminal only when said fuse alarm contact is extended to the alarm position.
