ABSTRACT:
A fuse clip for cartridge type fuses which permits the insertion of a proper fuse while preventing the insertion of improper fuses. The clip permits the insertion of fuses having an annular groove around one of the end terminals while prohibiting the insertion of fuses without such annular groove. A main body member has a pair of flexible clamping arms which receive the cartridge-type fuse, and the clamping arms have aligned slots therein. A rejection member comprised of a C-shaped configuration, with inward extensions formed on the legs of the C, is inserted into the main body member, with the inward extensions extending through the slots of the clamping arms. The inward extensions are spaced apart a distance greater than the diameter of the annular groove, but less than the diameter of the remainder of the end terminal. The rejection member prevents the insertion of fuses unless an annular groove on the end portion is positioned between the two inward extensions.
