## Abstract

Provided is an electrical junction box including a relief terminal portion having a structure in, which the relief terminal portion can be constituted with a small number of parts and high space efficiency. The electrical junction box includes: a box body; and a power supply distribution bus bar that is disposed in the box body and includes a power supply input terminal portion and power supply branch terminal portions that are connected by a plate-shaped conducting portion. The relief terminal portion is constituted by at least a portion of the plate-shaped conducting portion of the power supply distribution bus bar being disposed in a state of protruding from the outer surface of the box body and exposed to the outside.

## Claims

### Claim 1

An electrical junction box provided with a relief terminal portion to which a booster cable can be connected, the electrical junction box comprising:
a box body, and
a power supply distribution bus bar that is disposed in the box body and includes a power supply input terminal portion and power supply branch terminal portions that are connected by a plate-shaped conducting portion,
wherein the relief terminal portion is constituted by at least a portion of the plate-shaped conducting portion of the power supply distribution bus bar which protrudes from an outer surface of the box body and is exposed to the outside.

### Claim 2 (depends on 1)

The electrical junction box provided with the relief terminal portion according to claim 1,
wherein a fuse part formed by accommodating the plate-shaped conducting portion of the power supply distribution bus bar in a case is disposed in the box body, and
at least a portion of the case of the fuse part protrude from the outer surface of the box body, and the portion of the plate-shaped conducting portion constituting the relief terminal portion is exposed to the outside through an exposure window formed in the case.

### Claim 3 (depends on 2)

The electrical junction box provided with the relief terminal portion according to claim 2, wherein a cover member for covering the exposure window is attached to the case of the fuse part, and the cover member is movable between a covering position at which the exposure window is covered and an open position at which the exposure window is exposed to the outside.
