Such a design not only results in the whole volume increase of battery module, influences mass density, and battery holder has still increased the overall cost of battery module moreover.

In view of this, the present disclosure provides a connecting assembly and a battery module, which are used to provide a new connecting assembly.

As shown in fig. 1 to 4, the present application provides a connection assembly, where the connection assembly includes a main body portion 1 and a connection portion 2, the main body portion 1 is used for abutting against an object to be connected, specifically, along a length direction or a width direction of a battery unit, the main body portion 1 is respectively located at two opposite sides of the battery unit to clamp the battery unit. The battery unit may be a component formed by combining a plurality of battery cells, or may be a single battery cell.

The connecting portions 2 are used to be engaged with the main body portions 1, and when the battery module is assembled, the adjacent main body portions 1 are connected by the connecting portions 2.

The main body part 1 is further provided with a limiting part 11 and a matching part 12, the limiting part 11 can be matched with the matching part 12, when the battery module is assembled, the limiting part 11 of the main body part 1 can be matched with the limiting part 11 of the adjacent main body part 1, therefore, positioning is carried out when the battery module is installed, and the relative position accuracy of each battery unit is improved.
