A power fuse with zinc-aluminum terminals is provided. The power fuse includes a housing having a first end and a second end. Coupled to the housing at the first end is a first terminal assembly fabricated from a zinc-aluminum alloy, and coupled to the housing at the second end is a second terminal assembly also fabricated from the zinc-aluminum alloy. The first and second terminal assemblies include a copper plating entirely covering an exterior of the zinc-aluminum alloy. A fuse element assembly is positioned inside the housing and is electrically connected between the first terminal assembly and the second terminal assembly.

A compact fusible disconnect switch device includes a magnetic arc deflection assembly including at least a pair of magnets disposed about a switch contact assembly. The magnetic arc deflection assembly facilitates reliable connection and disconnection of DC voltage circuitry well above 125 VDC with reduced arcing intensity and duration. Multiple pairs of magnets may apply magnetic fields in directions opposing one another to deflect electrical arcs in different directions at more than one location in the switch contact assembly to facilitate high voltage DC operation.

A fuse (1) includes a fuse element (10) having a fusible portion (13) provided between opposed inner edges (11a, 12a) of flat plate portions (11, 12), and an insulating housing (50) covering the inner edge sides of the flat plate portions and the fusible portion in a state in which outer edge (11c, 12c) sides of the flat plate portions are protruded outward from slits at respective end walls (55, 58) of the insulating housing (50). The outer edge sides of the flat plate portions are formed as terminal portions (21, 22) each having a thickness twice as large as the thickness of the flat plate portion, and protrusions (11b, 12b) provided on upper and lower edges of the flat plate portions abut against inner surfaces of the end walls (55, 58) of the insulating housing (50).

The invention in this application aims to provide a multipolar fusible link in which its lateral width can decrease while its entire height does not increase. A multipolar fusible link (100) includes: an input terminal (110); a bus bar (120) through which an electric current input from the input terminal (110) flows; and a plurality of terminals (140) connected to the bus bar (120) via fusible sections (130). By changing a shape of a lower edge (122) of the bus bar (120) to which the fusible sections (130) are connected, a width between the lower edge (122) and an upper edge (121) positioned opposite the lower edge (122) is changed in accordance with the fusible sections (130) connected to the lower edge (122). In addition, shapes of the fusible sections (130) connected to the lower edge (122) are changed so that their lateral widths decrease.

A touch-safe fuse module includes a built-in slidable handle movable between extended and retracted positions relating to a housing of the fuse module. In the extended position, the handle assists with removal of the fuse from a base housing assembly by improving mechanical leverage to apply extraction force to the housing. Fuse modules having high current ratings may be effectively removed by hand without separately provided tools.
摘要:
A method for producing a fuse element having a fusible portion and any other portion which are made of different kinds of metal. The method comprises the steps of boring through-hole in a substrate made of first metal, forming an element plate by fusion-bonding a second metal to the through-hole and integrally stamping a pair of substrate portion made of the first metal and a low-melting-point portion made of the second metal. The second metal is made of a metal whose melting point is lower than that of the first metal. Further, the pair of substrate portion is connected together by the low-melting-point portion so that the fuse element is formed.

A fuse includes a tube, a pair of blade terminals projecting from opposite ends of the tube, at least one fuse element disposed in the tube and electrically coupled between the terminals, and a pair of metallic end caps disposed on opposite ends of the tube. Electrically insulative elements are disposed between the end caps and the terminals. The tube is filled with an arc-quenching material inserted through a fill hole that is plugged by a plastic drive rivet. Each terminal is attached to a metallic end plate by means of a staking tang inserted into a slot of the end plate, and by means of a separate solder joint. Each insulative element includes an axial sleeve through which a respective terminal extends for a part of its length. The fuse element having a one-piece metal element bent to form a pair of parallel, superimposed strips divided into sections by means of fusible weak points. The metal element also includes bridge elements which join sections of one strip to respective sections of the other strip, the bridges themselves being non-interconnected. End-most sections of one strip are fixedly joined to respective end-most sections of the other strip to define tabs for electrically connecting the fuse element to a circuit.
