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.

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.

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.

Exemplary embodiments of the present disclosure of a fuse may include a fuse body having a first portion and a second portion. The first and second portions may be configured to mate together thereby forming an internal cavity. A first inner termination and a second inner termination may be at least partially attachable to the first and second portions of the fuse body at respective first and second ends. A fusible element may be disposed in the cavity of the fuse body and extendable from the first inner termination at the first end of the fuse body to the second inner termination at the second end of the fuse body. The fusible element may be attachable to the first inner termination at a first connection and the second inner termination at a second connection. The first and second connections may be inspectable when the fuse is in an assembled state.

A fuse includes a case member that has a rectangular parallelepiped shape and has a space, a lid member that closes an upper opening of the case member and closely adheres to the case member, a fuse-element disposed in the space, and a pair of terminals, whose distal ends are exposed to outside, connected to both ends of the fuse-element. The case member includes a plurality of first engaging projections formed on a first side wall, and a plurality of second engaging projections formed on a second side wall. The lid member includes a plurality of first engagement recesses formed in a first contact wall and fitted respectively to the plurality of first engaging projections, and a plurality of second engagement recesses formed in a second contact wall and fitted respectively to the plurality of second engaging projections.

A fuse includes an integrated measuring function. In an embodiment, the fuse includes a fuse housing which in turn has a first receiving space delimited by a pressure body and a second receiving space which is spatially separated from the first receiving space and is delimited by a protective body, the first and second receiving spaces being arranged one behind the other in a direction of longitudinal extent. A fusible conductor is accommodated and mounted in the first receiving space and a measuring device is accommodated and mounted in the second receiving space. The measuring device has a current transformer and an electronic assembly which is electrically conductively connected to the current transformer. The current transformer and the electronic assembly are arranged one behind the other in the direction of longitudinal extent.
