An electrical connection box for a vehicle includes: an insertion housing into which multiple fuses are to be inserted through an open port on one side; multiple fuse terminals for connecting the fuses in the insertion housing to a substrate; a plate-shaped holding member that opposes the insertion housing from a side opposite to the one side of the insertion housing, and holds the multiple fuse terminals; and a case member that includes a flat plate portion for covering the multiple fuse terminals and has a notch that is formed in the covering portion, the holding member being arranged inside of the notch.

The electrical connection box includes a case, a frame that is made of a synthetic resin and whose position is fixed relative to the case, fixed terminals that are fixed to the frame and can be connected to external terminals, a fuse having terminals that are put over the fixed terminals, stud bolts for fastening the external terminals, the fixed terminals, and the terminals of the fuse together, and a holding member that holds the stud bolts. The frame includes an attached portion to which the holding member is attached.

A current distributor for a vehicle, having an input and a plurality of load channels which connect the input to a connected load via a safety fuse and a line in each case, and to a protection system for a vehicle having such a current distributor. In this case, a standby channel connects the input to the connected loads via an electronic fuse, wherein an evaluation and control unit checks the safety fuses for functionality and switches on a semiconductor switch of the electronic fuse and forms a redundant current path between the input and the connected loads via the standby channel if at least one of the safety fuses is identified as having been tripped.

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.

An electric connection box includes a base having a relay mounting portion on which a relay is configured to be mounted. The base has a component mounting portion on which a component is configured to be mounted at a lower position of the relay mounted on the relay mounting portion. The component mounting portion is disposed so that at least a part of the component mounting portion overlaps with an area of the base in which the relay is mounted in a plan view.

A fuse module including a mounting block formed of an electrically insulating material, a fuse plate including a fusible element disposed on a bottom surface of the mounting block, a fuse terminal electrically connected to the fusible element and extending along rear and top surfaces of the mounting block, and an input terminal electrically connected to the fusible element and extending from a front surface of the mounting block, the fuse module further including an electrically conductive terminal post extending from the top surface of the mounting block through the fuse terminal for facilitating connection to an electrical component.

A housing is provided with an electrical wire drawing path projecting toward outside and causing a plurality of at least one of an electrical wire bundle and the electrical wire to be drawn from inside to outside. The electrical wire drawing path includes a first wall member including two side portions extending in a projecting direction of the electrical wire drawing path, a second wall member disposed to be opposed to the first wall member with an interval, a first side wall member projecting from one side portion in a direction crossing an extending direction of the side portions and toward the second wall member, and a second side wall member projecting from the other side portion in a direction crossing an extending direction of the side portions and toward the second wall member.

Flat surfaces out of two flat surfaces of each of flat electrical connection bodies of a relay bus bar and a bus bar of an electronic component are mating surfaces brought into contact with each other by a fixing structure. At least one of the flat electrical connection bodies of the relay bus bar and the bus bar applies a reaction force accompanying the elastic deformation to the other flat electrical connection body, to which the one flat electrical connection body is to be connected, in a state in which the flat electrical connection body of the bus bar at an accommodation completion position in a housing has not been connected to the relay bus bar. The housing includes a receiving portion receiving a force applied to the flat electrical connection body of the bus bar from the flat electrical connection body of the relay bus bar.

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.
