The present invention provides a multi-link fuse capable of charging a battery with a configuration simpler than a conventional configuration, and a method for charging a battery by using the multi-link fuse. A multi-link fuse H includes a bus bar body that includes an input terminal, a plurality of external terminals, and a fusion portion provided between the input terminal and the external terminal, and a housing body that covers the bus bar body. The multi-link fuse H includes an extension bus bar for charging a battery by connecting a charging connection terminal. The extension bus bar includes an input extension terminal that overlaps the input terminal and an outer extension portion that extends outward from the bus bar body and connects the charging connection terminal. Both the extension bus bar and the bus bar body are fixed to the housing body in a state where the input extension terminal of the extension bus bar overlaps the input terminal.

A method for manufacturing a fusing busbar comprises a first disposing step of disposing wound second conductors on upper and lower surfaces of two opposite ends of a wound first conductor formed of a different material from the second conductors, a first rolling step of unwinding the first conductor and the second conductors and continuously feeding the first conductor and the second conductors to a rolling mill to continuously press-weld the second conductors onto the upper and lower surfaces of the two opposite ends of the first conductor, with a predetermined gap between the second conductors, and a first forming step of inserting a joined plate of the first conductor and the second conductors into a forming machine to press-form the joined plate into a busbar shape in which the second conductors are disposed on two opposite sides of the joined plate, and the first conductor is exposed in a middle of the joined plate.

The present application invention provides a fuse capable of saving space inside a casing even when the casing includes a plurality of fusion parts arranged side by side. A fuse includes: a fuse element including a fusion part provided between a pair of terminal portions; and a casing configured to house a part of the fuse element while causing the terminal portions to protrude outward. Two or more of the fusion parts are arranged in a lateral direction X orthogonal to a terminal portion direction Y connecting the terminal portions and connected to the terminal portions. The casing includes two casing split pieces configured to house the fuse element to sandwich the fuse element. The respective casing split pieces are fixed to each other by a frame-shaped fixing member configured to make one round of a periphery of the respective casing split pieces. A housing space N1 of the casing has a maximum width L1 in the vertical direction Z narrower than a maximum width L2 in the lateral direction X.

Therefore, the invention of the present application provides a fuse in which a position and a posture of a fuse element are easily stabilized and which is easily assembled, and a method for manufacturing the fuse. A fuse including a fuse element having a fusing portion; and a casing accommodating the fusing portion; where the fuse element has a long shape extending in a longitudinal direction of the casing and at least two or more fuse elements are provided; the fuse element has one end portion side coupled to each other by a coupling portion; a first holding portion that holds the fuse element is provided in one opening of the casing; and a locking portion that locks the coupling portion of the fuse element is provided in the first holding portion.

The present invention provides a fuse that can be easily manufactured and has an improved yield. A fuse includes an input terminal portion, a bus bar portion through which a current input from the input terminal portion flows, and a terminal portion connected to the bus bar portion through a fusible portion, where a fusible portion unit including the fusible portion and the terminal portion is provided in plurals, each of the fusible portion units is a separate body from the bus bar portion and is individually attached to the bus bar portion.

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.
