A fuse box for a battery of a vehicle includes: a lower housing having a space in which a fuse is housed and a bus bar for electrically connecting the battery and the fuse is seated; a plate-shaped upper housing having a through hole formed at a central portion thereof and a first extending portion extending upward along a circumference of the through hole, where the upper housing is assembled on an upper side of the lower housing; and a fuse cover that is coupled to an upper side of the upper housing to cover the fuse exposed through the through hole of the upper housing.

Provided is an electrical connection box in which a greater number of fuses can be inserted while suppressing an increase in size. An electrical connection box for a vehicle includes: an insertion housing that has a rectangular open port on one side and in which a plurality of rectangular insertion holes into which fuses are to be respectively inserted are provided facing the open port; a first insertion hole row in which a plurality of the insertion holes are provided side by side in a lengthwise direction of the open port, with long sides of the insertion holes adjacent to each other; and a second insertion hole row in which a plurality of the insertion holes are provided side by side in the lengthwise direction of the open port, with short sides of the insertion holes adjacent to each other.

A hybrid power distribution central unit (1) is described, which comprises a housing (box) (2), provided with at least one cover (3) and internally defining a plurality of seats for coupling modules (12, 13, 14) of specific types, said housing (box) (2) comprising a power supply module (11) in order to electrically feed all the functional modules (12, 13, 14) coupled to the housing (box) (2). The functional modules are interchangeable according to their dimensions and not according to their specific types, thus, being possible for the hybrid power distribution central unit (1) to simultaneously use functional modules of different types.

A junction box assembly and a terminal assembly configured to prevent a short circuit is provided. In one aspect, the terminal assembly includes a pair of terminals spaced apart from each other and a spacer configured to retain the pair of terminals in a fixed position with respect to each other. In another aspect, the spacer includes a plurality of fuses, and each fuse is electrically connected to a corresponding slot so as to help prevent a power surge through a respective output portion of the terminal. In yet another aspect, the terminal housing has a side wall having a rib extending a height at least as high as the combined height of the output portion and terminal connector when the two are laid on top of each other, preventing the terminal connector from coming into contact with an adjacent terminal connector.

An overcurrent protection device for distributing power to a component. A cartridge may removeably receiving a TPA fuse. The cartridge may include a power input terminal and a power output terminal. When the cartridge is removeably received by a power distribution panel the power input terminal may directly couple to a power input connection of the power distribution panel and the power output terminal may directly couple to a power output connection of the power distribution panel. The directly coupled power input terminal and power output terminal being void of an intermediate busbar arranged between the cartridge and the power distribution panel.

The invention concerns a fuse box, comprising a busbar (6) and at least one fuse (8) connected to the busbar, each fuse including two opposite end portions (8A, 8B) and a central portion (82), at least the central portion of each fuse and a section of the busbar being encapsulated in a plastic coating layer. The central portion (82) includes a part (84) of reduced cross-section. The two end portions (8A, 8B) include two respective electrical connectors (81A, 81B), and at least the two electrical connectors (81A, 81B) of each fuse (8) are not encapsulated in the plastic coating layer, so that a new fuse (12) can be connected between the two electrical connectors (81A, 81B) in replacement of a blown fuse (8).

A fuse holder includes a holder base comprising a plurality of protrusions each having a mounting hole formed therein to provide for mounting of the holder base to an external component and one or more mating protrusions and one or more mating slots formed on each of opposing side surfaces. The fuse holder also includes an input stud coupled to or formed on the holder base and a cover configured to attach to the holder base to at least partially enclose one or more fuses positionable on the fuse holder. The one or more mating protrusions and the one or more mating slots formed on each of the opposing side surfaces of the holder base comprise dovetailed protrusions and slots of a matching profile capable of receiving such a dovetailed protrusion, so as to enable a side-by-side stacking and interlocking of fuse holders with such mating protrusions and mating slots.
