Abstract

A tool for the removal or installation of a fuse includes a first tool arm and a second tool arm pivotally mounted to the first tool arm about an axis. A second fuse holder spreader finger section is movable away from a first fuse holder spreader finger section and a second fuse pusher finger section is movable toward a first fuse pusher finger section in response to a first handle section being moved toward a second handle section.

First claim

What is claimed is:

1. A tool, comprising:
a first tool arm comprising a first handle section, a first fuse holder spreader finger section and first fuse pusher finger section; and
a second tool arm pivotally mounted to the first tool arm about an axis, the second tool arm comprising a second handle section, a second fuse holder spreader finger section and a second fuse pusher finger section, the second fuse holder spreader finger section movable away from the first fuse holder spreader finger section and the second fuse pusher finger section movable toward the first fuse pusher finger section in response to the first handle section being moved relative to the second handle section; wherein the first fuse holder spreader finger section and the second fuse holder spreader finger section each comprise two fingers and the first fuse pusher finger section and the second fuse pusher finger section each comprise two fingers and wherein the first fuse holder spreader finger section and the second fuse holder spreader finger section are outboard of the first fuse pusher finger section and the second fuse pusher finger section.

2. The tool as recited in claim 1 , wherein the first tool arm and the second tool arm are identical.

3. The tool as recited in claim 1 , further comprising a hinge-pin fastener that passes through the second tool arm and the first tool arm along the axis.

4. The tool as recited in claim 1 , further comprising an interfering structure on at least one of the first handle section and the second handle section that operate as a stop to limit movement of the first handle section with respect to the second handle section.

5. The tool as recited in claim 1 , further comprising a grip surface on the first handle section and the second handle section.

6. The tool as recited in claim 1 , wherein the first fuse pusher finger section and the second fuse pusher finger section each form a hook to capture a fuse.

7. The tool as recited in claim 6 , wherein the hook comprises a ramp section to push the fuse away from a surface of a circuit card assembly.

8. A tool for the removal or installation of a fuse, comprising: a first tool arm comprising a first handle section from which extends a first tool arm first fuse holder spreader finger, a first tool arm first fuse pusher finger, a first tool arm second fuse pusher finger and a first tool arm second fuse holder spreader finger, and a second tool arm pivotally mounted to the first tool arm about an axis with a single hinge-pin fastener that passes through the first tool arm and the second tool arm along the axis, the second tool arm comprising a second handle section from which extends a second tool arm first fuse holder spreader finger, a second tool arm first fuse pusher finger, a second tool arm second fuse pusher finger and a second tool arm second fuse holder spreader finger, the second tool arm first fuse holder spreader finger adjacent to the first tool arm first fuse holder spreader finger, the second tool arm first fuse pusher finger adjacent to the first tool arm first fuse pusher finger, the second tool arm second fuse pusher finger adjacent to the first tool arm second fuse pusher finger, the second tool arm second fuse holder spreader finger adjacent to the first tool arm second fuse holder spreader finger.

9. The tool as recited in claim 8 , wherein the second tool arm first fuse holder spreader finger pivots away from the first tool arm first fuse holder spreader finger and the second tool arm second fuse holder spreader finger pivots away from the first tool arm second fuse holder spreader finger in response to the first handle section being moved toward the second handle section.

10. The tool as recited in claim 8 , wherein the second tool arm first fuse pusher finger pivots toward the first tool arm first fuse pusher finger and the second tool arm second fuse pusher finger pivots toward the first tool arm second fuse pusher finger in response to the first handle section being moved toward the second handle section.
