Abstract

A wiring module includes a busbar for connecting between electrode terminals, an external connection busbar to be connected to an external terminal, a resin protector including a first holding portion for holding the busbar and a second holding portion for holding the external connection busbar and a main cover for covering the first holding portion. The main cover includes a first auxiliary cover for covering the second holding portion and a second auxiliary cover connected to the first auxiliary cover via a hinge portion. The first auxiliary cover is provided with an interfered portion for interfering with an interfering portion of the second holding portion as the main cover is mounted on the resin protector, and the first auxiliary cover is automatically rotated and arranged at a predetermined position by the interference of the interfered portion and the interfering portion.

First claim

1 . A wiring module to be mounted on an electrical storage element group formed by arranging a plurality of electrical storage elements including positive and negative electrode terminals, comprising:
a connecting member for connecting between adjacent ones of the electrode terminals; an external connecting member including an external connection terminal to be connected to another device; an insulating holding member including a first holding portion for holding the connecting member and a second holding portion for holding the external connecting member; and a main cover for covering the first holding portion, wherein: the main cover is integrally provided with an auxiliary cover for covering the second holding portion via a first hinge portion; the auxiliary cover includes a first auxiliary cover connected to the first hinge portion and a second auxiliary cover integrally coupled to the first auxiliary cover via a second hinge portion perpendicular to the first hinge portion; and the first auxiliary cover includes an interfered portion for interfering with an interfering portion provided on the insulating holding member as the main cover is mounted on the insulating holding member, the first auxiliary cover is rotated with the first hinge portion as a rotary axis by the interference of the interfering portion and the interfered portion, and the first auxiliary cover is arranged at a predetermined position with the main cover mounted on the insulating holding member.

2 . The wiring module of claim 1 , wherein:
the external connecting member includes a base portion, an erected portion erected from the base portion and the external connection terminal provided to project from the erected portion, and the second holding portion includes a holding wall surrounding the base portion; the interfering portion is an erected wall erected from the holding wall for covering a surface of the erected portion opposite to the one where the external connection terminal is provided; and the interfered portion is a wall portion connected to the first hinge portion out of the first auxiliary cover.

3 . The wiring module of claim 2 , wherein the erected wall is formed with an inclined rotation guiding portion for guiding the rotation of the first auxiliary cover by coming into contact with the wall portion.

4 . The wiring module of claim 3 , wherein the first auxiliary cover and the second holding portion are provided with posture guiding portions for bringing the interfered portion of the first auxiliary cover in a proper posture into contact with the interfering portion prior to the rotation of the first auxiliary cover.

5 . The wiring module of claim 4 , wherein the first auxiliary cover includes a rotation restricting portion for restricting excessive rotation of the first auxiliary cover.

6 . The wiring module of claim 5 , wherein the main cover is integrally provided to the insulating holding member via a main body hinge portion.

7 . The wiring module of claim 1 , wherein the first auxiliary cover and the second holding portion are provided with posture guiding portions for bringing the interfered portion of the first auxiliary cover in a proper posture into contact with the interfering portion prior to the rotation of the first auxiliary cover.

8 . The wiring module of claim 1 , wherein the first auxiliary cover includes a rotation restricting portion for restricting excessive rotation of the first auxiliary cover.

9 . The wiring module of claim 1 , wherein the main cover is integrally provided to the insulating holding member via a main body hinge portion.
