Each of connection units integrally includes a cover via a hinge, and the cover covers an accommodation portion in which a connecting member is arranged. The connection unit includes a unit stopper and a unit stopper receiver that is fitted to the unit stopper that is formed on an adjacent connection unit. The cover includes a cover stopper and a cover stopper receiver that is fitted to the cover stopper formed on the cover of the adjacent connection unit. The connection units are connected to each other by fitting of the unit stoppers and the unit stopper receivers and fitting of the cover stoppers and the cover stopper receivers.

Battery connecting assembly

A battery wiring module is configured to be attached to a battery group including a plurality of batteries each having electrode terminals including a positive electrode terminal and a negative electrode terminal and configured to connect the electrode terminals. The battery wiring module includes a plurality of connection units connected to each other in a battery arrangement direction in which the batteries are arranged. Each of the connection units includes a bus bar and a bus bar housing. The bus bar is configured to connect one of the electrode terminals of one of the batteries and one of the electrode terminals of another one of the batteries. The bus bar housing houses the bus bar. The bus bar has a pair of terminal through holes configured to receive the electrode terminals and each of the terminal through holes is formed in a shape elongated in the battery arrangement direction.

Battery wiring module

A battery wiring module attached to a battery group formed by juxtaposing a plurality of batteries each having electrode terminals, includes: a plurality of bus bars; and a plurality of holder units made of an insulating resin and having holding portions and holding the bus bars. The holder units include: a first holder unit disposed at an end; and a second holder unit which is a holder unit other than the first holder unit. The holding portion of the second holder unit is provided with a bus bar insertion portion through which the bus bars are inserted in the direction in which the batteries are juxtaposed, and the second holding portion of the first holder unit is provided with an encompassing wall and adapted to insert the bus bars in a direction in which the first holder unit is attached to the battery group.

A battery wiring module to be attached to a cell group includes a plurality of cells each having positive and negative electrode terminals. The battery wiring module includes a busbar connecting the electrode terminals, a voltage sensing terminal overlapped with the busbar and connected to one of the electrode terminals, and an insulation protector including a housing and a wire guiding groove. The voltage sensing terminal is configured to sense a state of the cell group. The busbar and the voltage sensing terminal are housed in the housing. The wire guiding groove is configured to guide a sensing wire that extends from the voltage sensing terminal to extend out of the housing. In the housing, a bus bar lock tab and a sensing terminal lock tab are formed on one elastic locking piece.
