Mechanical disconnect switch with integrated fuse protection
First Claim
1. A circuit protection assembly for a mechanical disconnect switch having integrated fuse protection comprising:
- a mounting block having a bore extending therethrough and a recess cavity on a first surface of the mounting block;
a post having a first end disposed within the recess cavity, a second end, and a body portion extending through the bore, the body portion configured to receive a terminal and the second end configured to receive a securing mechanism;
a fuse having a centrally disposed aperture, the fuse configured to receive the body portion of the post and to receive the terminal for connection to a circuit to be protected; and
an insulator proximately superposed on the terminal and proximately disposed beneath the securing mechanism, the insulator configured to isolate the second end of the post from the terminal and the fuse while allowing the securing mechanism to apply an amount of torque, the insulator including a tether coupled thereto.

Abstract
A circuit protection assembly (CPA) is disposed between a source of power and a circuit to be protected. The CPA comprises a mounting block having a bore extending therethrough and a recess cavity on a first surface of the mounting block. A post having a first end is disposed within the recess cavity and a body portion extends through the bore. The body portion configured to receive a terminal and the second end configured to receive a securing mechanism. A fuse having a centrally disposed aperture is configured to receive the body portion of the post and to receive the terminal for connection to a circuit to be protected. An insulator disposed on the terminal and disposed beneath the securing mechanism. The insulator configured to isolate the post from the terminal and the fuse while allowing the securing mechanism to apply an amount of torque.

9. A circuit protection assembly comprising:
-
a mounting block having a recess cavity in an upper surface of the mounting block; a fuse having an upper fuse terminal, a lower fuse terminal, and a fuse element disposed orthogonal to the upper fuse terminal and the lower fuse terminal, the upper fuse terminal having a centrally disposed aperture configured to align with the recess cavity such that the fuse is disposed partially around the mounting block, the fuse element is retained adjacent to a wall of the mounting block, the wall being disposed orthogonal to the upper surface and a lower surface of the mounting block, and the lower fuse terminal is retained adjacent to the lower surface; and an insulator proximately superposed on the upper fuse terminal and proximately disposed beneath a securing mechanism, the insulator configured to isolate the securing mechanism from the fuse while allowing the securing mechanism to apply an amount of torque, wherein the insulator is a washer having a protective layer. - View Dependent Claims (10, 11)
