The invention relates to a power distribution unit (1), such as a fuse box for a vehicle, for providing a protected electrical connection between a power supply cable and a plurality of distribution cables (7). The unit comprises a housing (2) and, received in said housing: a bus bar (5) configured to be connected to the power supply cable; a plurality of fuses (10), each fuse comprising a body (15), a first end portion (11) configured to be connected to the bus bar (5), and a second end portion (12) configured to be connected to a distribution cable (7); at least one retainer (20) for maintaining the bus bar (5) in position with respect to the housing (2); at least one positioner (40) for positioning the fuse first end portion (11) relative to the bus bar (5) along directions (X,Y) substantially parallel to the bus bar; a biasing member (30) configured to urge the fuse first end portion (11) towards the bus bar (5), to cause the fuse first end portion to remain in contact with the bus bar.

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.

The invention relates to a circuit board arrangement for electrical separation of leads, comprising a fuse board configured to hold an electrical fuse, wherein the fuse board has electrical leads and openings formed between adjacent electrical leads; and comprising an insulating member configured to receive the fuse board, wherein the insulating member has separators, wherein the separators are configured to insert into the openings and electrically separate the leads.

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 straight bus bar includes an axial direction and having a rigid first portion with a first contact surface connectable to a first fuse, an axially spaced rigid second portion with a second contact surface connectable to a second fuse, and a connecting portion electrically connecting the first portion and the second portion. The connecting portion is a resilient compensation portion having at least two lateral recesses extending from opposite sides into the bus bar making the connecting portion elastically bendable to allow a relative axial movement of the first and second portions when an axial force is applied to the bus bar.

The invention relates to a circuit board arrangement for electrical separation of leads, comprising a fuse board configured to hold an electrical fuse, wherein the fuse board has electrical leads and openings formed between adjacent electrical leads; and comprising an insulating member configured to receive the fuse board, wherein the insulating member has separators, wherein the separators are configured to insert into the openings and electrically separate the leads

A fuse holder includes a movable tab, a base, and a cover. A stud is affixed to the movable tab and secures a terminal of a bolt-down fuse. A second stud is affixed to the base and secures a second terminal of the bolt-down fuse. The base has a channel into which the movable tab is slidably inserted. The cover connects to the base and is located over the stud and the second stud.

A distributor block includes: a supply input having an input terminal for connecting an electrical conductor; and a plurality of outputs, each output of the plurality of outputs having an output terminal for connecting an electrical conductor. The supply input is electrically conductively connected to a first current bar. Each output is electrically conductively connected to a second current bar. Between the first current bar and the second current bar, a fuse and/or a switch is arranged to connect the first current bar to the second current bar. A receptacle configured to hold the fuse and/or the switch is provided between the first current bar and the second current bar.
