## Abstract

A connection module according to which positional movement of each housing unit can be performed independently and sagging can be suppressed. A connection module that is to be attached to a power storage element group formed by aligning multiple power storage elements includes: bus bars that are to be connected between electrode terminals of the power storage elements; multiple box-shaped housing units that insulate and house the bus bars; and multiple U-springs that are provided between a pair of opposing wall portions of adjacent housing units and that couple the adjacent housing units such that the distance between the adjacent housing units can extend and contract. The U-springs each include a U-portion and a pair of base end portions that are located on both ends of the U-portion and connect to the pair of wall portions. The multiple U-springs include at least two U-springs whose pairs of base end portions are at different positions in a height direction.

## Claims

### Claim 1

A connection module to be attached to a power storage element group formed by aligning a plurality of power storage elements having positive and negative electrode terminals, comprising:
bus bars to be connected between the electrode terminals;
a plurality of box-shaped housing units for insulating and housing the bus bars; and
a plurality of U-springs that are provided between a pair of opposing wall portions of adjacent housing units, that are U-shaped in a side view, and that couple the adjacent housing units such that a distance between the adjacent housing units can extend and contract,
wherein the U-springs each include a U-portion and a pair of base end portions that are located on both ends of the U-portion and connect to the pair of wall portions, and
the plurality of U-springs include at least two U-springs in which the pairs of base end portions are at different positions in a height direction, in a side view in a state of being provided on the pair of wall portions.

### Claim 2 (depends on 1)

The connection module according to claim 1, wherein
the plurality of U-springs include a downward U-spring in which the U-portion has an opening that faces downward, and an upward U-spring in which the U-portion has an opening that faces upward, in a plan view in a state of being provided on the pair of wall portions.

### Claim 3 (depends on 2)

The connection module according to claim 2, wherein
a spring length of the downward U-spring is longer than a spring length of the upward U-spring.

### Claim 4 (depends on 2)

The connection module according to claim 2, wherein
a spring width of the upward U-spring is wider than a spring width of the downward U-spring.

### Claim 5 (depends on 2)

The connection module according to claim 2, wherein
the upward U-spring is provided on both end portions on the wall portions in plan view, and
one said downward U-spring is provided at a central portion of the wall portions in plan view.

### Claim 6 (depends on 1)

The connection module according to claim 1, wherein
the plurality of U-springs are arranged such that the positions of the base end portions connected to the wall portions are symmetrical with respect to a center line in the height direction of the wall portions.
