## Abstract

In a busbar module for connecting a plurality of batteries of a battery unit, the batteries are arranged so that electrodes of each of the batteries having different polarities are disposed adjacent to each other. The busbar module includes a plurality of busbars, a plurality of terminals, a plurality of wires, a plurality of plates and a connector. The busbars connect the electrodes adjacent to each other. The terminals are connected to the busbars respectively to detect a voltage of the batteries. The wires are connected to the terminals respectively. The plates accommodate the busbar, the terminals and the wires, and provided above the battery unit. The connector connects the plates together.

## Claims

### Claim 1

A busbar module for connecting a plurality of batteries of a battery unit in which the batteries are arranged so that electrodes of each of the batteries having different polarities are disposed adjacent to each other, the busbar module comprising:
a plurality of busbars that connect the electrodes adjacent to each other;
a plurality of terminals connected to the busbars respectively to detect a voltage of the batteries;
a plurality of wires connected to the terminals respectively;
a plurality of plates accommodating the busbar, the terminals and the wires, and provided on an upper surface of the battery unit; and
a connector connecting the plates together and including:
a plate portion which is erected so as to extend along a direction which is orthogonal to the busbars and in which the plurality of batteries are aligned;
a lock portion provided on the plate portion; and
a lock receiving portion which is locked to the lock portion.

### Claim 2 (depends on 1)

The busbar module as set forth in claim 1, wherein
the connector includes:
a second connecting piece formed with a hole portion and parallel to the busbars; and
a first connecting piece which includes a projecting portion formed thereon and configured to be inserted into the hole portion.

### Claim 3 (depends on 2)

The busbar module as set forth in claim 2, further comprising:
erected wall portions which are provided on the first connecting piece so as to be erected therefrom; and
a lock projection which is provided on at least one of the erected wall portions so as to hold the second connecting piece between the first connecting piece and the lock projection.

### Claim 4 (depends on 2)

The busbar module as set forth in claim 2, further comprising:
a fixing member which is inserted into an interior of the hole portion in a state where a wire of the plurality of wires is laid on the second connecting piece so as to be wound around outer circumferences of the second connecting piece and the wire, so as to fix the wire to the second connecting piece thereafter.

### Claim 5 (depends on 1)

The busbar module as set forth in claim 1, further comprising:
a rib which is configured to be brought into abutment with the plate portion when the plate portion is moved in a direction which intersects the aligned direction.

### Claim 6

A power supply unit, comprising:
a plurality of batteries of a battery unit in which the batteries are arranged so that electrodes of each of the batteries having different polarities are disposed adjacent to each other; and
a busbar module for connecting the plurality of batteries of the battery unit, the busbar module comprising:
a plurality of busbars that connect the electrodes adjacent to each other;
a plurality of terminals connected to the busbars respectively to detect a voltage of the batteries;
a plurality of wires connected to the terminals respectively;
a plurality of plates accommodating the busbar, the terminals and the wires, and provided on an upper surface of the battery unit; and
a connector connecting the plates together and including:
a plate portion which is erected so as to extend along a direction which is orthogonal to the busbars and in which the plurality of batteries are aligned;
a lock portion provided on the plate portion; and
a lock receiving portion which is locked to the lock portion.
