First Claim
Patent Images
1. A high voltage, high ampacity, fused quick disconnect for alternately connecting and disconnecting an electrical power supply to/from an electrical load comprising:
- an input terminal receiving electrical current from said supply, said terminal having a first electrically conductive sleeve defining a first opening adapted to snugly receive a first electrically conductive rod;
an output terminal receiving electrical current from said input terminal for delivering said current to said load, said output terminal having a second electrically conductive sleeve defining a second opening adapted to snugly receive a second electrically conductive rod;
an insulated housing holding said terminals side-by-side and apart from each other;
a cover for said housing;
a first electrically conductive rod secured to said cover and conforming substantially to said first opening for engaging and disengaging said first sleeve;
a second electrically conductive rod secured to said cover and conforming substantially to said second opening for engaging and disengaging said second sleeve; and
a replaceable, current sensitive fuse having a first terminus detachably secured to said first rod in said cover, and a second terminus detachably secured to said second rod in said cover to conduct electrical current between said rods under normal current load conditions, and to fail open under overload current conditions;
whereby placement of said cover on said housing electrically couples said terminals together and removal of said cover electrically disconnects said terminals one from the other when said fuse is intact, and permits ready replacement of said fuse off-line from said power supply when said fuse has failed.

Abstract
A high ampacity, high voltage, fused electrical disconnect having a pair of input and output terminals carried by a housing and in registry with a pair of input and output rods carried by a cover and connected to each other by a fuse. The rods are readily detachable from the cover and the fuse. A switch in the housing signals when the rods are engaged with the terminals.
