  • Patent number: 4971582
    Abstract: A reject type fuse clip for use with a cartridge type fuse having a grooved ferrule includes a fuse clip having a pair of upstanding clamping arms and a reject member disposed therebetween. The upstanding clamping arms of the fuse clip are provided with a receptor means, such as a web formed therein by a pair of slots, which is adapted for engagement by the reject member. The reject member includes a pair of spaced shoulder portions, with each shoulder portion having a slot in its underside adapted to engage the web members provided on each upstanding clamping arm of the fuse clip. The slots are configured so that the web member flexes during insertion into the slot, after which the reject member may not be removed from the fuse clip without damage to either the reject member or the fuse clip. A lead connecting collar is formed integrally with the fuse clip.
