A fuse holder provides a safe device for connecting fuses to a three-phase busbar device. Each phase includes a corresponding load conductor and line conductor mounted within a housing. A mechanical lock is provided for each phase that locks a knife of the fuse to one of the conductors for the phase. In a further aspect, the fuse knives are frictionally locked within the housing. In both the mechanical lock and frictional lock, a release mechanism is provided that can be activated by a screwdriver to release the fuse knives from the fuse holder. In another aspect, certain conductors are provided with heat dissipation wings that contact the housing to dissipate heat generated by current flowing through the conductor.

An electrical assembly may include a bus bar assembly, a fuse connected to the bus bar assembly, a contactor connected to the bus bar assembly, a bracket connected to the bus bar assembly, and/or a cooling member connected to the bracket such that the fuse is indirectly connected to the cooling member via the bus bar assembly and the bracket. A method of operating an electrical assembly may include controlling the contactor to provide current from a power source to a load, generating heat via the current flowing through the fuse, conducting the heat from the fuse to the bus bar assembly, conducting the heat from the bus bar assembly to the cooling member, and/or dissipating the heat via the cooling member.

A fluid-affected fuse includes a structural housing, a pair of electric terminals, one or more fuse elements, and a fluid arranged in an internal volume of the structure. The structure provides rigidity to the fuse. The terminals are coupled to the structural housing and are configured to be coupled to an electric power circuit of a battery circuit. The one or more fuse elements are electrically connected in series to the pair of electric terminals and are arranged in the internal volume. The fluid is configured to affect a temperature of the fuse element. A fluid-filled fuse is filled with fluid, optionally sealed, and operated with the increased heat capacity of the fluid to affect temperature of the fuse. A fluid-cooled fuse is filled with the fluid, undergoing a stream of the fluid thus allowing control of fuse temperature. A control system controls the fluid stream and fuse operation.

An easy-to-assemble fuse has a fusible body, a socket, and a cover. The fusible body is engaged with the socket. The cover is covered on the socket and the fusible body and is engaged with the socket. By the engagement between the fusible body and the socket and the engagement between the socket and the cover, the fuse achieves the purpose of fast alignment and positioning. The fuse can be quickly assembled during the manufacturing process, thereby simplifying the manufacturing process, and reducing the production cost.

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.
