摘要： A lightweight industrial fuse has a housing and a conductive fuse. The housing has a first plastic half-housing and a second half-housing combined with each other. The conductive fuse is integrally formed and clamped between the first and second half-housing. The conductive fuse has a fusible body and two intermediary portions disposed within the housing, and two electrode portions exposed from two opposite ends of the housing. Thus, an enclosed accommodation cavity of the housing is defined through the combination of the first and second half-housing. A manufacturing process is simplified, and a manufacturing cost is decreased, and further a weight of the industrial fuse is effectively reduced.

摘要： A fuse includes multiple stacked layers, a first terminal, and a second terminal. The first terminal is connected to one end of a fusible element and the second terminal is connected to the other end. The stacked layers include first and second intermediate layers and a special layer. The first intermediate layer, which has a centrally disposed opening, is stacked on the first terminal and the second terminal. The second intermediate layer, also having a centrally disposed opening is stacked above the first intermediate layer, and the centrally disposed openings define a chamber above the fusible element. The special layer is located between the first intermediate layer and the second intermediate layer and includes one or more geometric elements. The geometric elements divide the chamber into two sub-chambers, the first sub-chamber being above the second sub-chamber.

摘要： An electrical device assembly and method to attach an isolated single stud fuse assembly to an electrical device are disclosed. The electrical device assembly consists of multiple studs, one or more of which is replaced with the isolated single stud fuse. A conductive copper landing zone receives an electrically isolated steel stud. When the landing pad assembly is orbital riveted into a plastic housing of the electrical device, the stud is locked into the housing permanently. Electrical devices such as disconnect switches and power distribution modules, both of which include multiple studs, are good candidates for being adapted with the single stud fuse assembly.

摘要： A fuse housing for safe outgassing of a fuse is disclosed. The fuse housing features labyrinth walls disposed at opposing sides of the fuse housing. The labyrinth walls feature serpentine paths for the flow of outgassing material. At an end of the serpentine paths which is farthest away from a fuse element are vent channels. The vent channels are narrower in depth than that of the serpentine paths of the labyrinth walls, facilitating a suctioning effect during outgassing. Conductive material deposits along the serpentine paths so that the fuse maintains a high OSR rating. By directing and controlling the outflow of gases, the fuse housing is able to reduce the temperature of the gases produced. The fuse housing is also able to reduce the physical and observable effects of outgassing.

摘要： There is provided an electric-power conversion apparatus in which smoke emission, a burnout, and short-circuiting between a melted material and a peripheral member can be suppressed even when a fuse portion is melted by an excessive current. An electric-power conversion apparatus includes an electric power semiconductor device, an electrode wiring member, a case, a fuse portion formed in the electrode wiring member, a fuse resin member disposed between the fuse portion and the case, and a sealing resin member that seals the electric power semiconductor device, the electrode wiring member, the fuse portion, and the fuse resin member in the case.

摘要： A high-capacity miniature cartridge fuse is provided. A fuse includes a cylindrical housing, a fusible wire, and first and second deep-drawn ferrules fabricated from aluminum alloy. The aluminum is plated with nickel. The ferrule includes a side wall and an end wall. The side wall surrounds the first or second end of the housing, and has a thickness of approximately 0.50 mm or less. The end wall includes a boss extending toward an interior of the housing, and has a thickness greater than the thickness of the side wall.

摘要： The present utility model relates to a fuse, a vehicle circuit for an electric vehicle, and an electric vehicle. The fuse has a longitudinal direction and a transverse direction, and includes: a bushing, having a through-hole cavity extending in the longitudinal direction and for accommodating quartz sand and two end surfaces in the longitudinal direction; a fuse body, accommodated in the through-hole cavity; and two contact blades, positioned at two ends of the through-hole cavity and conductively joined to the fuse body. At least one of the contact blades comprises a first section coming into direct sealing contact with one of the end surfaces of the bushing by covering the through-hole cavity, and an overhanging arm section extending from the first section. The overhanging arm section includes a second section extending, in a direction perpendicular to the longitudinal direction, out of the bushing.

摘要： A fuse assembly including a fuse connected to two busbars, an injection molded base and an injection molded cover. The busbars are powder-coating with a powder-based adhesive or adhesion promoter, then cured in an oven. The busbars are then placed in the cavity image of an injection molding apparatus. Plastic is heated to a liquid form and injected into the cavity image. The resulting injection molded base is resistant to both dust and water, protecting the fuse inside.
