## Abstract

An electrical junction box includes a frame body, a rescue terminal portion formed in a rectangular parallelepiped shape in a plan view and including a longitudinal side face, two lateral side faces connected to the longitudinal side face, and an upper face, a resin cover configured to cover the longitudinal side face, the two lateral side faces and the upper face. The resin cover includes a rotary shaft extending along the longitudinal side face and provided on a side where the longitudinal side face is provided and on a base end portion of the rescue terminal portion opposite to the upper face, the resin cover being configured to rotate with respect to the frame body about the rotary shaft.

## Claims

### Claim 1

An electrical junction box comprising:
a frame body;
a rescue terminal portion formed in a rectangular parallelepiped shape in a plan view and including a longitudinal side face, two lateral side faces connected to the longitudinal side face, and an upper face, wherein the longitudinal side face is longer than each of the two lateral side faces; and
a resin cover configured to cover the longitudinal side face, the two lateral side faces and the upper face,
wherein the resin cover includes a rotary shaft extending along the longitudinal side face and provided on a side where the longitudinal side face is provided and on a base end portion of the rescue terminal portion opposite to the upper face, the resin cover being configured to rotate with respect to the frame body about the rotary shaft.

### Claim 2 (depends on 1)

The electrical junction box according to claim 1,
wherein a rotation hinge structure configured to rotatably hold the resin cover is configured to allow the resin cover to be attached to and detached from the rescue terminal portion only when the resin cover is at a fully open position, and
wherein only after the rescue terminal portion is detached from the frame body, the resin cover can rotate to the fully open position.

### Claim 3

An electrical junction box comprising:
a frame body;
a rescue terminal portion formed in a rectangular parallelepiped shape in a plan view and including a longitudinal side face, two lateral side faces connected to the longitudinal side face, and an upper face; and
a resin cover configured to cover the longitudinal side face, the two lateral side faces and the upper face,
wherein the resin cover includes a rotary shaft extending along the longitudinal side face and provided on a side where the longitudinal side face is provided and on a base end portion of the rescue terminal portion opposite to the upper face, the resin cover being configured to rotate with respect to the frame body about the rotary shaft,
wherein a rotation hinge structure configured to rotatably hold the resin cover is configured to allow the resin cover to be attached to and detached from the rescue terminal portion only when the resin cover is at a fully open position, and
wherein a lock arm configured to detachably hold the rescue terminal portion with respect to the frame body is configured to hold the resin cover at a position immediately before the fully open position.
