Battery wiring module
A battery wiring module that can ensure an insulation distance between an electrode of a secondary battery and a conductive part arranged above the cover portion. A housing includes first and second divided housings that respectively include a bus bar housing portion that houses a bus bar, a first cover portion that is provided in one piece with the first divided housing and covers an opening of the bus bar housing portion of the first divided housing, and a second cover portion that is provided in one piece with the second divided housing and covers an opening of the bus bar housing portion of the second divided housing, the first and second cover portions being adjacent to each other. The first cover portion is provided with a tongue piece that extends from the first cover portion toward the second cover portion and overlaps the second cover portion in the opening direction of the bus bar housing portion.
1. A battery wiring module comprising:
a housing that is to be attached to a secondary battery for a vehicle;
bus bars to be connected to electrodes of the secondary battery that are inserted into the inside of the housing; and
electrical wires connected to the bus bars,
the housing including a first divided housing and a second divided housing each having a bus bar housing portion that houses one of the bus bars, a first cover portion that is provided in one piece with the first divided housing and covers an opening of the bus bar housing portion of the first divided housing, a second cover portion that is provided in one piece with the second divided housing and covers an opening of the bus bar housing portion of the second divided housing, the bus bar housing portions of the first and second divided housings being adjacent to each other, and the first and second cover portions being adjacent to each other,
wherein the first cover portion is provided with a tongue piece having a first extending portion and a second extending portion, the first extending portion extends from the first cover portion toward the bus bar housing portion, and the second extending portion extends from an end of the first extending portion toward the second cover portion and overlaps the second cover portion in the opening direction of the bus bar housing portion.
2. The battery wiring module according to claim 1 ,
wherein the tongue piece is positioned on the inside of the bus bar housing portion relative to the second cover portion.
3. The battery wiring module according to claim 2 ,
wherein the tongue piece includes a protruding portion that protrudes from a part overlapping the second cover portion in the direction away from the second cover portion.
