Abstract

Provided is an electrical junction box capable of housing an electric component while absorbing the tolerance of the electric component. The electrical junction box is an electrical junction box that is to be mounted in a vehicle, including: a casing that forms an outer shell; and a fixation member that fixes, to the casing, an electric component that is to be electrically connected to a vehicle-mounted load or an electricity storage device mounted in the vehicle, wherein a slit for absorbing a tolerance associated with external dimensions of the electric component is provided in the fixation member.

First claim

What is claimed is:

1. An electrical junction box that is to be mounted in a vehicle, comprising:
a casing that forms an outer shell;
a fixation member including a plurality of wall members, the fixation member fixing, to the casing, an electric component that is to be electrically connected to a vehicle-mounted load or an electricity storage device mounted in the vehicle, the plurality of wall members surrounding at least a portion of an outer peripheral surface of the electric component,
wherein a slit for absorbing a tolerance associated with external dimensions of the electric component, the slit is provided in each of adjacent two wall members of the plurality of wall members; and
wherein the fixation member includes a fastening portion that fastens the electric component, and the fastening portion is provided at a corner portion formed by the adjacent two wall members.

2. The electrical junction box according to claim 1 , wherein a rib extending along the slit is provided on a surface of the wall member in which the slit is provided, on the electric component side, and
the rib extending along the slit comes into contact with the outer peripheral surface of the electric component.

3. The electrical junction box according to claim 1 , wherein a reinforcing portion that covers a portion of the slit is provided on a surface of the wall member in which the slit is provided, on a side opposite to the electric component.

4. The electrical junction box according to claim 1 , wherein the casing includes a box member having an opening, and
the plurality of wall members are inner walls provided inside the box member.

5. The electrical junction box according to claim 2 , wherein a reinforcing portion that covers a portion of the slit is provided on a surface of the wall member in which the slit is provided, on a side opposite to the electric component.

6. The electrical junction box according to claim 1 , wherein the casing includes a box member having an opening, and
the plurality of wall members are inner walls provided inside the box member.

7. The electrical junction box according to claim 2 , wherein the casing includes a box member having an opening, and
the plurality of wall members are inner walls provided inside the box member.

8. The electrical junction box according to claim 3 , wherein the casing includes a box member having an opening, and
the plurality of wall members are inner walls provided inside the box member.
