摘要： A subsea-replaceable fuse assembly has at least one fuse and a wet-mateable fuse connector element. The connector element is arranged to connect the fuse assembly to a subsea electrical load requiring protection of the fuse. The fuse connector element has conductor elements that are electrically connected to the fuse. A corresponding method of protecting a subsea electrical load includes connecting a fuse to the load underwater in a wet-mating operation effected between connector elements that are electrically connected, respectively, to the fuse and to the load.

摘要： To provide a protection element, which evens the amount of flux on a fusible conductor and improves variations in fusing characteristics, even if voids occur in the flux which cause variations in the amount of the flux coated on the fusible conductor. A protection element (10) is provided with: an insulated substrate (11); a heating body (14); an insulating member (15); two electrodes (12); a heating body internal electrode (16); a fusible conductor (13) which is stacked over the two electrodes (12) from the heating body internal electrode (16) and fuses a current path between the two electrodes (12) by heating; a flux (17) coated on the fusible conductor (13) so as to superimpose on the heating body; and a cover member (1) attached to the insulated substrate covering at least the fusible conductor. The cover member (1) has a cylindrical protrusion (2) formed on an inner surface (1a) of the cover member (1) so as to contact the flux (17), and a communication hole (3) communicating with the inner surface (1a) side of the cover member (1) from the protrusion (2) is opened on a side wall surface of the cover member (1).

摘要： A subminiature circuit protector includes a substrate (18) carrying a metal fuse element (20) hermetically sealed in a glass sleeve cartridge (30). The fuse element may comprise a film deposited on the substrate, or, alternatively a metal strip or wire. Leads (40, 42) extend from opposing ends of the sleeve for connection in a circuit, and a gas is sealed in the sleeve to provide a suitable environment to improve operating lifetime and interrupting capability. The circuit protector is made by placing the substrate (18) carrying the fuse element (20) in the glass sleeve (30) and placing the leads in contact with the fuse element. The assembly is heated in the presence of a gas below atmospheric pressure to a temperature sufficient to soften the glass. The pressure is then increased to cause the ends of the glass sleeve (30) to form a hermetic seal about the leads (40, 42).

摘要： Un élément électrique (201), en particulier un fusible ou un élément à montage en surface, est formé en pulvérisant un conducteur aluminium (253, 553) sur un tube carré (251, 551), en emmanchant le tube sur un tube externe (231, 531), en plaçant un nombre de ces assemblages (280, 580) sur un agencement (270); en remplissant l'agencement et les assemblages avec un élément d'étanchéité vulcanisant en silicone et à température ambiante (212, 512); en durcissant l'élément d'étanchéité; en coupant les assemblages en segments (276); et en métallisant les extrémités de chaque segment. Selon un mode de réalisation, les tubes emmanchés (251, 231) sont mécaniquement séparés du silicone qui les entoure. Selon un autre mode, les tubes revêtus de silicone (551) sont mécaniquement séparés des tubes externes. Selon des modes de réalisation alternatifs, des fusibles (601, 651) sont fabriqués en pulvérisant les conducteurs (605, 655) sur un substrat en verre mince (603, 653), en couvrant une partie liante (607, 657) des conducteurs d'un adhésif en silicone (609, 659), et en découpant le substrat en cubes.

摘要： An electric fuse of the type which has a tubular fuse casing (12) and a solid fuse end terminal telescopically received within the fuse casing is provided with an annular seal (60) which is contained within an annular groove (36) formed in the outer lateral wall of the end terminal. The seal is formed from a settable material which has been injected into the groove through a seal injection opening (50) in the outer end of the end terminal which extends from the axial outer end and into fluid communication with an annular groove (48) provided in the end terminal. A seal material bleed opening is provided in the end terminal which also extends from the axial outer end of the end terminal and into fluid communication with the annular groove. The bleed opening is positioned substantially diametrically opposed to the seal injection opening.

摘要： A miniature fuse suitable for printed circuit applications and a manufacturing method therefor features preferably a generally rectangular elongated insulating body having a fuse element preferably diagonally disposed in a fuse cavity therein and terminals preferably insert molded therein and extending preferably from the opposite ends thereof. The cavity preferably opens onto opposite longitudinal sides of the body, but provision may be made to optionally close-off one of the cavity openings by a cover plate. The body is sealed by a sleeve which is preferably a semi-rigid expandable member but which could be a piece of expandable shrink tubing. Lay-in grooves preferably extend from the opposite ends of the cavity to conductive fuse attachment surfaces which are initially preferably bendable tabs located beyond the outer surface of the body to allow the fuse element to be conveniently attached or captured thereby during fuse assembly. The projecting tabs are then bent into the fuse body, and a preferably semi-rigid transparent insulating sleeve is then applied around and sealed to the sides of the body.

摘要： The present invention relates to a fuse link (1) used in alternate current medium- or high-voltage systems with a current frequency of 50Hz, comprising a spring-type striker pin (8), and designed for the protection of electrical devices against the consequences of short circuits and overloads. The fuse link (1) comprises a porcelain housing (2) with a star-core (3), external end caps (11) closed by plugs (10a, 10b), star-core end caps (5) with a ringshaped first tap (7) designed to ensure electric contact between the star-core end cap and the external end cap of the fuse link. The spring-type striker pin (8) is positioned along the axis of the star-core (1). Each of the end caps of the star-core (5) is provided with an additional second tap (7') that is designed to centre the star-core (3) relative to the axis of the fuse link and is located on the circumference of the end cap of the star-core (5) at an obtuse angle (α) relative to the tap (7). Both taps (7, 7') are provided with spring contacts (6) bent in the direction of the longitudinal axis of the fuse link. The spring-type striker pin is centred along the longitudinal axis of the fuse link using tongues (20a) of a disc spring (20), installed in one of the plugs (10b) closing the fuse link (1) on the side where the striker pin (8) is positioned.
