Abstract

Provided is a battery wiring module that can suppress a case in which a cover comes off. The battery wiring module includes a housing having a wire storage groove that stores multiple wires. The housing includes a first storage groove and second storage grooves that both extend in an X direction and are arranged side by side in a Y direction orthogonal to the X direction, and third storage grooves that are in communication with the first storage groove and the second storage grooves. The housing includes a first cover, second covers, and third covers that respectively cover the first storage groove, the second storage grooves, and the third storage grooves. The first cover has abutting portions that abut on outer surfaces on sides of the third covers opposite to the underside surfaces opposing the third storage grooves.

First claim

What is claimed is:

1. A battery wiring module comprising:
a plurality of wire terminals that are respectively connected to a plurality of bus bars that connect battery terminals of a plurality of battery cells;
a plurality of wires that are respectively connected to the plurality of wire terminals; and
a housing storing the plurality of wire terminals and the plurality of wires,
wherein the housing includes a first storage groove for storing the wires, a first cover for covering the first storage groove, a second storage groove for storing the wires, a second cover for covering the second storage groove, a third storage groove for storing the wires, and a third cover for covering the third storage groove,
each of the first storage groove and the second storage groove extends in a first direction,
the first storage groove and the second storage groove are spaced from each other in a second direction, the second direction being orthogonal to the first direction,
the third storage groove is in communication with the first storage groove and the second storage groove,
the third cover includes an underside surface that opposes the third storage groove and an outer surface on a side opposite to the underside surface, and
the first cover includes an abutting portion that extends over the third storage groove in the second direction and contacts the outer surface of the third cover.

2. The battery wiring module according to claim 1 , wherein
the plurality of wire terminals are arranged side by side in the extension first direction along each of the first storage groove and the second storage groove.

3. The battery wiring module according to claim 1 , wherein
the abutting portion protrudes toward the third storage groove relative to the first storage groove.

4. The battery wiring module according to claim 1 , wherein
the first cover includes engaging portions for engaging with the first storage groove, and
the engaging portions are provided at positions adjacent to the abutting portion.

5. The battery wiring module according to claim 4 , wherein
the engaging portions are provided on both sides of the abutting portion.

6. The battery wiring module according to claim 1 , wherein
the third cover is joined to the third storage groove via a hinge, and
the third cover is arranged at an open position at which the third storage groove is not covered, through rotation from a closed position at which the third storage groove is covered, to the outer surface side, using the hinge as an axis.

7. A battery wiring module comprising:
a plurality of wire terminals that are respectively connected to a plurality of bus bars that connect battery terminals of a plurality of battery cells;
a plurality of wires that are respectively connected to the plurality of wire terminals; and
a housing storing the plurality of wire terminals and the plurality of wires,
wherein the housing includes a first storage groove for storing the wires, a first cover for covering the first storage groove, a second storage groove for storing the wires, a second cover for covering the second storage groove, a third storage groove for storing the wires, and a third cover for covering the third storage groove,
the first storage groove and the second storage groove extend in the same direction as each other and are arranged side by side in a direction orthogonal to the extension direction,
the third storage groove is in communication with the first storage groove and the second storage groove,
the third cover includes an underside surface that opposes the third storage groove and an outer surface on a side opposite to the underside surface,
the first cover has an abutting portion that abuts on the outer surface of the third cover, and
the second cover includes an extension portion that extends over the third storage groove in the orthogonal direction.

8. The battery wiring module according to claim 1 , wherein
the third storage groove extends in the second direction.

9. The battery wiring module according to claim 1 , wherein
each of the first storage groove and the second storage groove includes a bottom wall and side walls extending in the first direction, and the third storage groove extends between a side wall of the first storage groove and a side wall of the second storage groove that face and are adjacent to each other in the second direction.

10. The battery wiring module according to claim 1 , wherein
the abutting portion extends downward such that a lower end of the abutting portion is positioned lower than an upper end of a side wall of the first storage groove.

11. The battery wiring module according to claim 1 , wherein
a lower surface of the abutting portion of the first cover contacts the outer surface of the third cover.
