Abstract

Provided is a battery wiring module including: a plurality of linear conductors disposed in parallel with a predetermined gap therebetween; a plurality of busbars disposed in parallel along at least one of the linear conductors disposed at both ends having a predetermined gap therebetween so as to electrically connect electrode terminals provided in at least two battery cells connected to each other in the same direction among the plurality of battery cells overlapping each other in the same direction, the electrode terminals being arranged in the same direction; a first insulating resin portion which integrally coats the outer peripheral portions of the plurality of linear conductors and a side edge portion adjacent to the linear conductor in the plurality of busbars; and a connection conductor which electrically connects the linear conductor and the busbar to each other.

First claim

What is claimed is:

1 . A battery wiring module comprising:
a plurality of linear conductors which is disposed in parallel with a predetermined gap therebetween; a plurality of busbars which is disposed in parallel along at least one of the linear conductors disposed at both ends while having a predetermined gap therebetween so as to electrically connect electrode terminals provided in at least two battery cells connected to each other in the same direction among the plurality of battery cells overlapping each other in the same direction, the electrode terminals being arranged in the same direction; an insulating resin portion configured integrally to coat outer peripheral portions of the plurality of linear conductors and side edge portions adjacent to the linear conductors in the plurality of busbars; and an electric connection portion configured electrically to connect the linear conductors and the busbars to one another, wherein the electric connection portion electrically connects an end of each of the linear conductors to the predetermined busbar, the linear conductor being formed by separating a gap between the plurality of linear conductors at one end of the insulating resin portion.

2 . A battery wiring module comprising:
a plurality of linear conductors which is disposed in parallel with a predetermined gap therebetween; a plurality of busbars which is disposed in parallel along at least one of the linear conductors disposed at both ends while having a predetermined gap therebetween so as to electrically connect electrode terminals provided in at least two battery cells connected to each other in the same direction among the plurality of battery cells overlapping each other in the same direction, the electrode terminals being arranged in the same direction; an insulating resin portion configured integrally to coat outer peripheral portions of the plurality of linear conductors and side edge portions adjacent to the linear conductors in the plurality of busbars; and an electric connection portion configured electrically to connect the linear conductors and the busbars to one another, wherein the electric connection portion is a connection conductor of which one end is provided with a press-contact connection portion press-connected to the predetermined linear conductor coated by the insulating resin portion and the other end is electrically connected to the predetermined busbar.

3 . The battery wiring module according to claim 1 , wherein
a cathode busbar to be electrically connected only to a cathode terminal and an anode busbar to be electrically connected only to an anode terminal are provided, and the cathode busbar and the anode busbar are provided with cut raised portions electrically connected to the predetermined linear conductor coated by the insulating resin portion.

4 . The battery wiring module according to claim 2 , wherein
a cathode busbar to be electrically connected only to a cathode terminal and an anode busbar to be electrically connected only to an anode terminal are provided, and the cathode busbar and the anode busbar are provided with cut raised portions electrically connected to the predetermined linear conductor coated by the insulating resin portion.

5 . The battery wiring module according to claim 1 , wherein
the side edge portion of the busbar is provided with a connection reinforcement portion which increases a connection force between the busbar and the insulating resin portion.

6 . The battery wiring module according to claim 2 , wherein
the side edge portion of the busbar is provided with a connection reinforcement portion which increases a connection force between the busbar and the insulating resin portion.

7 . The battery wiring module according to claim 3 , wherein
the side edge portion of the busbar is provided with a connection reinforcement portion which increases a connection force between the busbar and the insulating resin portion.

8 . The battery wiring module according to claim 1 , wherein
when the insulating resin portion is set as a first insulating resin portion, a second insulating resin portion integrally connecting opposite side edge portions which face the side edge portions of the plurality of busbars is provided in the opposite side edge portions.

9 . The battery wiring module according to claim 2 , wherein
when the insulating resin portion is set as a first insulating resin portion, a second insulating resin portion integrally connecting opposite side edge portions which face the side edge portions of the plurality of busbars is provided in the opposite side edge portions.

10 . The battery wiring module according to claim 3 , wherein
when the insulating resin portion is set as a first insulating resin portion, a second insulating resin portion integrally connecting opposite side edge portions which face the side edge portions of the plurality of busbars is provided in the opposite side edge portions.

11 . The battery wiring module according to claim 5 , wherein
when the insulating resin portion is set as a first insulating resin portion, a second insulating resin portion integrally connecting opposite side edge portions which face the side edge portions of the plurality of busbars is provided in the opposite side edge portions.
