Abstract

A fuse holder assembly for a vehicle generally includes an insulator configured for supporting a circuit lead terminal and insulating the circuit lead terminal from a bus bar. The insulator includes a fuse receiver, wherein the fuse receiver is configured to releasably receive a fuse.

Claims

1. A fuse holder assembly for a vehicle, the fuse holder assembly comprising:

an insulator configured for supporting a circuit lead terminal and insulating the circuit lead terminal from a bus bar, the insulator including a fuse receiver, wherein the fuse receiver is configured to releasably receive a fuse, wherein the insulator further includes a crown and wherein the circuit lead terminal is positionable to extend from the perimeter of the crown in a plurality of orientations around the perimeter of the crown different directions.

4. The fuse holder assembly of claim 1, wherein the insulator includes an anchor key to prevent rotation of the insulator relative to the bus bar after the insulator is positioned on the bus bar.

5. The fuse holder assembly of claim 1, wherein the insulator includes a channel for receiving the fuse receiver.

6. The fuse holder assembly of claim 1, wherein the insulator includes a bore for receiving a mounting device for coupling the fuse holder assembly to the bus bar.

7. The fuse holder assembly of claim 1, wherein the fuse receiver includes first and second fuse clips, the first and second fuse clips being discrete and unconnected from one another, wherein the first fuse clip has an electrical connection with the circuit lead terminal and the second fuse clip has an electrical connection with the bus bar, and wherein the fuse, when received, provides an electrical connection between the first fuse clip and the second fuse clip.

8. The fuse holder assembly of claim 1, wherein the circuit lead terminal includes a terminal ring for receiving a mounting device and an insulating ring for providing insulation between the terminal ring and the mounting device.

9. The fuse holder assembly of claim 1, wherein the fuse is a standard blade fuse.

10. The fuse holder assembly of claim 1, wherein the fuse receiver is disposed within the insulator.

20. The fuse holder assembly of claim 1, wherein the insulator is an insulation block.

2. (canceled)

3. A fuse holder assembly for a vehicle, the fuse holder assembly comprising:

an insulator configured for supporting a circuit lead terminal and insulating the circuit lead terminal from a bus bar, the insulator including a fuse receiver, wherein the fuse receiver is configured to releasably receive a fuse, wherein the insulator further includes a crown having a plurality of detents for positioning the circuit lead terminal in a plurality of orientations on the insulator.

11. (canceled)
