Abstract

An electrical junction box includes a container and a relay that is installed on an outer surface of the container. A busbar protrudes from the outer surface of the container and is connected to the relay. A support wall protrudes from the outer surface of the container, is provided opposite to the busbar, and supports the relay. The relay is interposed between the busbar and the support wall, and the busbar has a guide portion configured to guide insertion of the relay between the busbar and the support wall.

First claim

What is claimed is:

1. An electrical junction box comprising:
a container;
a relay that is installed on an outer surface of the container;
a busbar having a body portion and a connecting portion, the body portion is disposed on an under surface of the container and the connecting portion that extends through the container so as to protrude from the outer surface of the container, wherein the connecting portion is connected to the relay; and
a support wall that protrudes from the outer surface of the container, is provided opposite to the connecting portion of the busbar, and supports the relay,
wherein the relay is interposed between the connecting portion of the busbar and the support wall, and
the connecting portion of the busbar has a guide portion configured to guide insertion of the relay between the busbar and the support wall.

2. The electrical junction box according to claim 1 , wherein the guide portion is a curved surface formed by curving a protruding end of the connecting portion of the busbar to a side opposite to the support wall.

3. The electrical junction box according to claim 2 , wherein
the body portion is elongated in one direction; and
the connecting portion is contiguous with one end portion of the body portion, and
another end portion of the body portion has an elongated hole that is elongated in the one direction.

4. The electrical junction box according to claim 2 , wherein the busbar has a thickness of 1 mm or more.

5. The electrical junction box according to claim 1 , wherein the guide portion is an inclined surface that is formed at a protruding end of the connecting portion of the busbar, and is inclined such that a distance to the support wall increases toward the protruding end.

6. The electrical junction box according to claim 5 , wherein the
body portion is elongated in one direction; and
the connecting portion is contiguous with one end portion of the body portion, and
another end portion of the body portion has an elongated hole that is elongated in the one direction.

7. The electrical junction box according to claim 5 , wherein the busbar has a thickness of 1 mm or more.

8. The electrical junction box according to claim 1 , wherein the
body portion that is elongated in one direction; and
the connecting portion is contiguous with one end portion of the body portion, and
another end portion of the body portion has an elongated hole that is elongated in the one direction.

9. The electrical junction box according to claim 8 , wherein the busbar has a thickness of 1 mm or more.

10. The electrical junction box according to claim 1 , wherein the busbar has a thickness of 1 mm or more.
