Connection module

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.
