Abstract

A fuse holder includes a movable tab, a base, and a cover. A stud is affixed to the movable tab and secures a terminal of a bolt-down fuse. A second stud is affixed to the base and secures a second terminal of the bolt-down fuse. The base has a channel into which the movable tab is slidably inserted. The cover connects to the base and is located over the stud and the second stud.

First claim

The invention claimed is:

1 . A fuse holder comprising:
a first stud to secure a first terminal of a bolt-down fuse; a base upon which a second stud is affixed, the second stud to secure a second terminal of the bolt-down fuse, the base further comprising:
a first dovetail connector disposed on a first side of the base;
a first dovetail opening disposed adjacent the first dovetail connector on the first side of the base;
a first lock ramp disposed adjacent the first dovetail opening on the first side of the base;
a second dovetail connector disposed on a second side of the base;
a second dovetail opening disposed adjacent the second dovetail connector on the second side of the base; and
a first lock ramp receiver disposed within the second dovetail connector.

2 . The fuse holder of claim 1 , wherein the first side of the base is coupled to a mounting tab.

3 . The fuse holder of claim 2 , wherein the mounting tab further comprises:
a third dovetail connector; a third dovetail opening disposed adjacent to the third dovetail connector; and a second lock ramp receiver disposed adjacent the third dovetail connector.

4 . The fuse holder of claim 3 , wherein:
the first dovetail connector of the first side of the base couples to the third dovetail opening of the mounting tab; the first dovetail opening of the first side of the base couples to the third dovetail connector of the mounting tab; and the first lock ramp of the first side of the base couples to the second lock ramp receiver of the mounting tab.

5 . The fuse holder of claim 1 , wherein the first side of the base is coupled to a second fuse holder.

6 . The fuse holder of claim 1 , wherein the second side of the base is coupled to a mounting tab.

7 . The fuse holder of claim 6 , wherein the mounting tab further comprises:
a third dovetail connector; a third dovetail opening disposed adjacent the third dovetail connector; and a second lock ramp disposed within the third dovetail opening.

8 . The fuse holder of claim 1 , wherein the second side of the base is coupled to a second fuse holder.

9 . The fuse holder of claim 1 , further comprising:
a movable tab upon which the first stud is affixed.

10 . The fuse holder of claim of claim 7 , wherein:
the second dovetail connector of the second side of the base couples to the third dovetail opening of the mounting tab; the second dovetail opening of the second side of the base coupled to the third dovetail connector of the mounting tab; and the first lock ramp receiver of the second side of the base couples to the second lock ramp of the mounting tab.
