Abstract

Provided is a wiring module configured to be attached to a power storage device group in which a plurality of power storage devices are lined up, the wiring module including a voltage detection wire to be connected to at least one of the plurality of power storage devices. An insulation protector is configured with an engagement receiving portion. A detection wire cover covers the voltage detection wire and includes a cover engagement portion that engages with the engagement receiving portion. A cover support portion is formed in the insulation protector, the cover support portion abutting against the detection wire cover from a direction opposite to a disengagement direction in which the engagement portion and the engagement receiving portion disengage from each other, when a force is applied to the detection wire cover in the disengagement direction.

First claim

The invention claimed is:

1. A wiring module configured to be attached to a power storage device group in which a plurality of power storage devices are lined up, the wiring module comprising:
a conductive member configured to be connected to at least one of the plurality of power storage devices;
an insulation protector that has an opening in which the conductive member is accommodated and that includes a cover engagement receiving portion; and
a cover that is attached to the insulation protector and covers the conductive member and that includes a cover engagement portion that engages with the cover engagement receiving portion,
wherein a cover support portion is formed in the insulation protector, the cover support portion abutting against the cover from a direction opposite to a disengagement direction in which the cover engagement portion and the cover engagement receiving portion disengage from each other, when a force is applied to the cover in the disengagement direction.

2. The wiring module according to claim 1 ,
wherein an abutment rib is formed in a portion of the cover that opposes the cover support portion, the abutment rib extending in a direction that intersects the disengagement direction and abutting against the cover support portion when a force is applied to the cover in the disengagement direction.

3. The wiring module according to claim 2 ,
wherein in a state in which no force is applied to the cover in the disengagement direction, a clearance is formed between the cover support portion and the abutment rib, and a size of the clearance is set to be smaller than an engagement margin between the cover engagement portion and the cover engagement receiving portion.

4. The wiring module according to claim 1 ,
wherein the conductive member is a voltage detection wire that is configured to detect a voltage of at least one of the plurality of power storage devices.

5. The wiring module according to claim 1 ,
wherein the insulation protector and the cover are formed integrally with each other via a hinge.

6. The wiring module according to claim 1 ,
wherein the insulation protector has a plurality of joint units each having a joint portion,
the resin protector is formed by the plurality of joint units being joined together by the joint portions in a direction in which the plurality of power storage devices are lined up, and
the cover engagement portion and the cover support portion are formed in each of the plurality of joint units.

7. The wiring module according to claim 1 ,
wherein an intersecting wall intersecting the disengagement direction is provided in the insulation protector at a position forward of the cover engagement receiving portion with respect to the disengagement direction, and the cover support portion is formed in the intersecting wall.

8. The wiring module according to claim 7 ,
wherein a notch is provided in the intersecting wall,
a fitting portion to be fitted into the notch is provided in the cover, and
a lip abutment rib is formed in the fitting portion, the lip abutment rib extending in the disengagement direction and abutting against at least one of a pair of lip portions constituting the notch of the intersecting wall when a force is applied to the cover in a direction that intersects the disengagement direction.

9. The wiring module according to claim 8 ,
wherein the conductive member is a voltage detection wire that is configured to detect a voltage of at least one of the plurality of power storage devices.

10. The wiring module according to claim 9 ,
wherein the insulation protector and the cover are formed integrally with each other via a hinge.

11. The wiring module according to claim 10 ,
wherein the insulation protector has a plurality of joint units each having a joint portion,
the resin protector is formed by the plurality of joint units being joined together by the joint portions in a direction in which the plurality of power storage devices are lined up, and
the cover engagement portion and the cover support portion are formed in each of the plurality of joint units.
