Abstract

A battery wiring module may include connecting members for connecting adjacent electrode terminals to each other, an external connection terminal that is connectable to another device, and a resin protector having holding portions that hold the connecting members and the external connection terminal. A lid portion for covering the external connection terminal may be provided integrally with the resin protector via a first hinge. The lid portion may be provided with a second hinge having a hinge axis that is orthogonal to a hinge axis of the first hinge. A first lid portion that is formed by folding the first hinge and a second lid portion that is formed by folding the second hinge can be disposed in directions crossing each other.

Claims

1. A battery wiring module comprising:

a plurality of connecting members that connect adjacent electrode terminals to each other;

an external connection terminal that is configured to be connectable to another device;

a resin protector comprising a plurality of first holding portions that hold the connecting members and a second holding portion that holds the external connection terminal, the second holding portion having an opening portion; and

a lid portion that (i) covers the external connection terminal and (ii) is provided integrally with the resin protector via a first hinge, the lid portion comprising;

a second hinge that comprises a hinge axis that is orthogonal to a hinge axis of the first hinge;

a first lid portion formed by folding the first hinge; and

a second lid portion that is formed by folding the second hinge and that is connected to the first lid portion via the second hinge,

wherein;

the first lid portion and the second lid portion are disposed in directions crossing each other,

the second lid portion is configured to cover the opening portion of the second holding portion so that the external connection terminal is covered with the lid portion, and

the second lid portion has a rectangular parallelepiped shape, and a front side, a lower side, and a right side thereof are entirely open.

2. The battery wiring module according to claim 1, wherein the resin protector is provided with a locking structure that holds the lid portion in a state in which the first hinge is folded.

3. The battery wiring module according to claim 1, wherein:

the second holding portion is provided with a holding wall surrounding the external connection terminal, and

the first lid portion is formed by folding the first hinge in a direction toward an outer side of the second holding portion and is configured to be locked on an outer side surface of the holding wall that is on the opposite side to the side of the external connection terminal.

4. The battery wiring module according to claim 2, wherein:

the second holding portion is provided with a holding wall surrounding the external connection terminal, and

the first lid portion is formed by folding the first hinge in a direction toward an outer side of the second holding portion and is configured to be locked on an outer side surface of the holding wall that is on the opposite side to the side of the external connection terminal.

5. The battery wiring module according to claim 1, wherein the battery wiring module is attached to a single cell group in which a plurality of single cells having cathode and anode electrode terminals are lined up.

6. The battery wiring module according to claim 1, wherein the resin protector is made from synthetic resin.

7. The battery wiring module according to claim 1, wherein the first hinge is connected to an edge portion of a bottom plate of the second holding portion.

8. The battery wiring module according to claim 1, wherein the first lid portion comprises:

an oblong rectangular portion connected to the first hinge; and

a locking plate portion that (i) is disposed perpendicularly with respect to the rectangular portion and (ii) has an L-shaped cut out defined therein that locks with a locking protruding portion disposed on a wall of the resin protector.

9. The battery wiring module according to claim 1, wherein the first lid portion is formed by folding the first hinge in a direction towards an inner side of the second holding portion.
