Battery wiring module
A battery wiring module is to be combined with a battery module including a plurality of battery cells stacked in a state of being alternatively reversed so that a positive electrode terminal and a negative electrode terminal are adjoined between the adjacent battery cells. The battery wiring module is provided with a plurality of linear conductors which are arranged at an interval, a plurality of bus bars which are arranged at an interval along to at least one side of the plurality of linear conductors so that each of the plurality of bus bars electrically connects the positive electrode terminal and the negative electrode terminal adjacent to each other, and an insulation resin part including both a covering part for covering an outer periphery of the plurality of linear conductors and a bus bar connection part.
1. A battery wiring module to be combined with a battery module including a plurality of battery cells stacked in a state of being alternatively reversed so that a positive electrode terminal and a negative electrode terminal are adjoined between the adjacent battery cells, the battery wiring module comprising:
a plurality of linear conductors which are arranged at an interval;
a plurality of bus bars which are arranged in parallel with the plurality of linear conductors and arranged at an interval along to at least one side of the plurality of linear conductors so that each of the plurality of bus bars electrically connects the positive electrode terminal and the negative electrode terminal adjacent to each other; and
an insulation resin part including both a covering part for covering an outer periphery of the plurality of linear conductors and a bus bar connection part,
wherein the bus bar connection part covers at least a part of each of through holes formed in side edges of the plurality of bus bars,
wherein the side edges are adjacent to the plurality of linear conductors, and
wherein each of the plurality of linear conductors is electrically connected to a respective one of the plurality of bus bars.
