A battery connection unit includes an electronic component electrically connected to a battery terminal and a terminal of an electric wire, and an insulating support member that includes a first support body and a second support body and that supports the electronic component, where the first support body is disposed across a space in such a way that a first gap to a first surface becomes a first reference gap, the second support body is disposed across a space in such a way that a second gap to a second surface becomes a second reference gap, at least one first spring member that contacts the first surface while maintaining the first reference gap after attachment to the battery is disposed on the first support body, and at least one second spring member that contacts the second surface while maintaining the second reference gap is disposed on the second support body.

An electrical fuse assembly includes electrically conductive first and second electrodes, and a bimetallic fuse element. The bimetallic fuse element electrically connects the first and second electrodes. The bimetallic fuse element is configured to disintegrate, and thereby disconnect the first electrode from the second electrode, in response to a current exceeding a prescribed trigger current of the bimetallic fuse element for at least a prescribed duration.

A safety fuse includes a housing, a first contact blade having a protruding portion protruding from the housing along a first direction, a second contact blade having a protruding portion protruding from the housing, and a fusion section enclosed in the housing and connecting the first contact blade and the second contact blade. The protruding portion of the first contact blade includes two lateral edges extending in the first direction and a linear bend arranged on one of the lateral edges. The bend extends in a second direction perpendicular to the first direction.

A circuit protection assembly includes a mounting block, a unitary fuse assembly, a post assembly and a plug connector. The unitary fuse assembly is disposed the mounting block and includes a plurality of fuses each of which is defined by a portion of a bus plate disposed on the lower surface of the mounting block to form a first terminal of the fuse, a second terminal disposed at least partially on the upper surface of the mounting block and a fuse element connecting the first terminal and the second terminal. The post assembly is disposed at least partially within the mounting block and a post extending from the block. The plug connector extends from a portion of the first terminal of at least one of the plurality of fuses.

A busbar includes a plurality of main terminals (upstream side terminal, downstream side terminals) and one auxiliary terminal conductively connected to one of the main terminals and is press-formed in an integrated manner. The auxiliary terminal is connected to the main terminals through connection bars which are all cut off, except for one, in a cutting process after a pressing process, and the circuit configuration can be changed by selectively cutting off the connection bars. Therefore, there is no need to change the shape of a press die, and the production efficiency can be improved using a die having a uniform shape.

An electrical unit includes a first housing member, a second housing member, and a fuse assembly connected to the first housing member. The first housing member and the second housing member may provide a chamber to receive at least one electrical connector such that the fuse assembly is disposed at least partially between the first housing member and the at least one electrical connector. The first housing member may be configured to retain said at least one electrical connector. The fuse assembly may include a plurality of fuses having current capacities of at least 80 amps. The fuse assembly may include a bus bar and a plurality of fuses fixed to the bus bar. Each of said at least one electrical connector may include a plurality apertures or recesses disposed in a plurality of rows and a plurality of columns.

Fuse assemblies are disclosed. In one implementation, a fuse assembly may be disposed that includes a first portion of the second portion. The first portion may be formed of a first metal. The second portion may be formed of a second metal different from the first metal. The second metal may be copper, and the copper may be tin plated or silver plated.
