Abstract: A fuse holder, particularly for interlocked sockets and electrical apparatuses in general, includes a tray which is inserted in a seat and is adapted to accommodate a fuse. The tray is movable along a rectilinear path, having at least two positions: an active position, in which the fuse is active, and an extracted position, in which the fuse can be removed from the tray. The seat includes two elastic contact members which provide an electrical and mechanical connection of the fuse in the active position.

Abstract: In an exemplary embodiment, a fuse body includes a first end, a second end and a bore extending therethrough for receiving a fuse element assembly. The bore includes a clearing portion having a first cross sectional area and a positioning portion having a second cross sectional area. The first cross sectional area is larger than the second cross sectional area. The positioning portion provides a receptacle for receiving the fuse element assembly and ensuring that the fuse element is substantially centered within the clearance portion.

Abstract: There is disclosed a fuse with a secondary short-circuit prevention mechanism in which a melting portion, when melted, will not be brought into an unstably supported-condition, thereby positively preventing the melting portion from being again short-circuited. A fuse element 23 includes a pair of parallel terminal portions 29 and 29 interconnected by a connecting portion 31, and a fusible portion 33 is formed at the connecting portion 31. A housing 25 includes terminal receiving chambers for respectively receiving the terminal portions 29 and 29, and a fuse element receiving space for receiving the connecting portion 31, the terminal receiving chambers communicating with the fuse element receiving space.

Abstract: In a different nuts assembling construction in which according to the kind of nuts 71, 73, there are provided plural pairs of nut fitting grooves 61, 63 into which both sides of seats 75, 77 of nuts 71, 73 are fitted, the thicknesses D1, D2 of seats 75, 77 of nuts 71, 73 are formed in a manner to be different for each kind of the nuts 71, 73; and the groove thicknesses of the nut fitting grooves 61, 63 are formed by being matched to the thicknesses D1, D2 of corresponding seats 75, 77, so that where an attempt is made to fit the 71, 73 into wrong nut fitting grooves 61, 63, the thicknesses D1, D2 of the seats 75, 77 are not matched to the groove thicknesses of the nut fitting grooves 61, 63, whereby a worker can easily detect that the kind of the nuts 71, 73 is wrong.

Abstract: A female fuse assembly includes a female fuse and a housing. The female fuse includes a first and a second female terminal portion each having a face portion which includes a first end, a second end, a first side, and a second side, includes a first clamping arm and a second clamping arm, includes a first bracing arm and a second bracing arm, and includes a fuse link having a first terminal extension and a second terminal extension, and having a skived region for controlling the resistance between the first and second female terminal portions. The fuse link further includes a first terminal bend and a second terminal bend. The first terminal bend is positioned substantially toward the second end of the first face portion, or vice versa, and the second terminal bend is positioned substantially toward the first end of the second face portion, or vice versa, for increasing the length of the fuse link.

Abstract: Disclosed is a fusible link which assures that a fuse element is completely and firmly received in a housing without any occurrence of incorrect contact of a male terminal with an opponent female terminal. Lances slantwise extending from a fuse element received in a housing are engaged with stepped engagement portions. While a cover is fitted to the housing, a plurality of projections extending from the cover are brought in contact with electrical contact portions of the fuse element so that the fuse element is firmly received in the housing at a predetermined position. Consequently, the fuse element is reliably received in the housing in the double engaged state without an occurrence of incorrect insertion of the fuse element.

Abstract: An object of the present invention is to provide a connection box for plural kinds of fusible links each having different dimensions wherein the connection box is constructed in such a manner as to allow the respective fusible links to be firmly fitted to the connection box with excellent stability. The connection box for plural kinds of fusible links is integrally molded of a heat-resisting synthetic resin and includes a horizontal box-shaped portion and a vertical wall portion as essential components. An opposing pair of common slots are formed through a bottom wall of the horizontal box-shaped portion while extending not only in parallel with each other but also in parallel with the opposite side walls defining a peripheral wall of the horizontal box-shaped portion. The interior of the peripheral wall is stepwise recessed so an to enable plural kinds of fusible links each having different dimensions to be received therein.

Abstract: A shock-safe fuse holder for a cartridge fuse is provided which can be readily installed in a mating receptacle and removed therefrom for fuse replacement. The fuse holder includes a visual indicator for denoting a blown or missing fuse. The cartridge fuse is substantially enclosed within the holder to limit the access to the electrical contacts of the cartridge fuse to minimize the danger of electrical shock. The holder has a configuration for retaining the holder in a mating fuse receptacle even in the absence of an installed fuse.

Abstract: A subminiature fuse comprising two terminals, a substrate, a fusible conductor, ceramic coating, a second coating and a unitary housing. A ceramic substrate 80 plated at both ends is inserted into fingers (70) in terminal, a fusible wire element 10 is strung between the fingers (70) and (20, 30) and electrically connects the terminal (20, 30). The assembly 160 is encased in a ceramic adhesive 180 which is encased in a second material (200) with superior dielectric properties. The ceramic encased assembly is enclosed in a unitary housing by injection molding.

Abstract: The present invention constitutes a fuse which comprises a glass envelope having a solid base portion; there being a lead-in conductor of Dumet metal projecting through the base and into the interior of the envelope. The inner end of the lead-in conductor is rigidly engaged to the inner end portion of a filament. The other end of the filament extends into the solid base and is therein fixedly joined to the inner end of a lead-out conductor formed of Dumet metal. The said conductors in their outer ends are suitably connected to terminals or posts in a base plug which supports the glass envelope.

Abstract: A fusible electric contactor having a plurality of cavities and a movable member having a path of movement into the cavities. A fuse assembly is removably inserted within the cavities to occupy a volume within the confines of the height, width, and length of the contactor.
