Fuse link and dual element fuse
First Claim
1. A one-piece alloy overload fuse link comprising a body having an opening at one end and a fuse link connector extending from the other end of said body, a bore formed in said body, said bore having an open end a closed end, said body opening forming the bore open end bore formed in said body wherein when there is an overload current said fuse link connector separates from said fuse link body.

Abstract
We provide an overload fuse link that is generally used in cartridge type fuses along with a short-circuit fuse link. The overload fuse link is prepared from a solder alloy and is directly attached to the interior of one of the cartridge fuse terminals. The overload fuse link has an open bore opening at one end and a connector extending from the other end. The cartridge fuse which uses the fuse link also has an insulator through which the connector passes and the insulator separates the short circuit fuse link from the body section of the overload fuse link wherein when there is an overload, the fuse link connector electrically separates from the fuse link body section.
