Abstract: A fuse block 1 includes a fuse box 2 and a high voltage fuse 3. The fuse box 2 has a high voltage mounting part 6. The high voltage mounting part 6 is provided with an opening 6a, a plurality of surrounding walls 7a, 7b, and projections 8. Each of the projections 8 is projected from both the surrounding walls 7a, 7b which are adjacent to each other into an interior of the high voltage mounting part 6. A rated voltage fuse cannot be mounted to the high voltage mounting part 6 because of the presence of the projections 8. The high voltage fuse 3 includes a housing 10 having outer walls 14a, 14b and recesses 13. Each of the recesses 13 is formed by displacing both the outer walls 14a, 14b which are adjacent to each other. When the high voltage fuse 3 is mounted to the high voltage mounting part 6, the recesses 13 and the projections 8 will not interfere with each other.

Abstract: A fuse holder including a housing defining an enclosed region and an opening to the enclosed region, a pair of contacts at opposite ends of the enclosed region and spaced to engage end cap terminals on the ends of a tubular fuse moved into the enclosed region, and a fuse carrier that is pivotally mounted on the housing at the housing opening and movable between a closed position, in which the contacts electrically engage the end cap terminals and the opening is closed by the carrier, and an open position, in which a fuse can be inserted into the fuse carrier, the fuse carrier defining an elongated fuse insertion region for receiving the tubular fuse, one end of the region being sized to receive a small diameter projection on the end of the tubular fuse but to block a full diameter end of a fuse of the same diameter, the opening to the housing being sized to permit closure of the carrier with a tubular fuse having a small diameter projection in the one end, but to block closure of a fuse having the same overal

Abstract: A fuse bolder used to be mounted on a circuit board for holding a cartridge fuse and comprising a pair of clips each having a stop provided integrally on their clip bodies at an upper end thereof so that the cartridge fuse, when it is inserted into the fuse holder while it is axially biased, is restrained from being inserted thereinto because it strikes the stop of the corresponding clip body.

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.

Abstract: A rejection fuseholder (10) for Class CC fuses (30) having a leaf spring (22) to hold fuse (30) in contact with rejection contact assembly (14). Spacer (16) prevents fuses other than Class CC fuses from making electrical contact with rejection contact assembly (14). Assembly contact (14) is concave in shape and of a diameter greater than rejection nipple on fuse (30) so that electrical contact is made all around the circumference of rejection nipple of fuse (30) and centers fuse (30) in the contact.

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.

Abstract: A rejection-type fuse block is disclosed for use with Class CC cartridge-type fuses having ferrules at opposite ends, the ferrule at one end having a cap of smaller diameter than the ferrule. An insulated rejection collar having a rejection opening sized to allow the cap to pass therethrough while preventing passage of the ferrule is positioned between the fuse and an electrically conductive terminal. A leaf spring located at the end of the fuse opposite the cap end serves to axially press the fuse towards the insulated rejection collar and the cap into contact with the terminal. Fuse clips are provided for releasably securing the clip in proper position.

Abstract: A single integral molded red plastic article, of star shape, having a central body portion with radiating arms at the ends of which are blocking elements of cylindrical shape. The blocking elements are of different sizes. In use, a selected one the blocking elements is pushed into one of the pair of fuse clips, after the fuse is removed. The selected blocking element is so selected according to the size of the fuse clip. The remaining blocking elements extend outwardly and serve as a grip for handling the article, and as a visual signal.
