Abstract

A wiring module that is to be attached to a unit cell group in which a plurality of unit cells that each have positive and negative electrode terminals are arranged, including a plurality of basic units arranged in a direction in which the unit cells are arranged. Each of the plurality of basic units includes: a bus bar configured to electrically connect the electrode terminals of two adjacent unit cells to each other; an electrical wire that is to be electrically connected to the unit cells to detect a state of the unit cell group; a fuse configured to electrically connect the bus bar and the electrical wire to each other, and prevent an overcurrent; and a housing provided with a fuse opening into which the fuse is inserted, and a bus bar opening into which the bus bar is inserted. The fuse opening opens in a direction in which the bus bar extends.

First claim

1 . A wiring module that is to be attached to an electricity storage device group in which a plurality of electricity storage devices that each have positive and negative electrode terminals are arranged, comprising:
a plurality of basic units that are arranged in a direction in which the electricity storage devices are arranged, wherein each of the plurality of basic units includes: a bus bar that is configured to electrically connect the electrode terminals of two adjacent electricity storage devices to each other; an electrical wire that is to be electrically connected to the electricity storage devices to detect a state of the electricity storage device group; an overcurrent protection device that is configured to electrically connect the bus bar and the electrical wire to each other, and prevent an overcurrent from flowing through the electrical wire; and a housing that is provided with a protection device opening into which the overcurrent protection device is inserted, and a bus bar opening into which the bus bar is inserted, and the protection device opening opens in a direction in which the bus bar extends.

2 . The wiring module according to claim 1 ,
wherein the electrical wire is drawn out from a proximal end portion of the housing, a distal end portion of the housing that is located opposite the proximal end portion of the housing is provided with an electrical wire holding piece, the plurality of basic units include one basic unit and another basic unit that are arranged adjacent to each other, the proximal end portion of the housing of the one basic unit and the distal end portion of the housing of the other basic unit are arranged adjacent to each other, and the electrical wire that is drawn out from the proximal end portion of the one basic unit is held by the electrical wire holding piece of the other basic unit.

3 . The wiring module according to claim 2 ,
wherein the distal end portion of the housing of the other basic unit is offset relative to the proximal end portion of the housing of the one basic unit, in a direction in which the electrical wire is drawn out from the proximal end portion.
