Abstract
The disclosed rejection fuse holder for accepting grooved-terminal cartridge fuses and rejecting ungrooved-terminal cartridge fuses utilizes rejection elements having fuse-engaging edges of special sharpness that dig into and block insertion of ungrooved fuse terminals. In a particularly economical fuse-clip terminal construction, each of a pair of fuse-gripping arms bears a length of wire as the rejection element, carried by its respective arm, with a sharp-edged end facing the direction of fuse insertion, assembled to the fuse-clip arm without resort to a fastening operation.
