Abstract

A secondary battery module includes a plurality of unit cells, and a connector electrically connecting the unit cells to each other. The connector has a surface contact portion, and the shape of the surface contact portion corresponds to the shape of terminals of the unit cell. The connector is fastened to a terminal of the unit cell by insertion.

Claims

1. A secondary battery module, comprising:

a plurality of unit cells, each of the plurality of unit cells having a metal case and terminals; and

a connector electrically connecting the unit cells to each other, the connector comprising a pair of terminal-receiving portions having a pair of holes and a bridge connecting the pair of terminal-receiving portions, the pair of terminal-receiving portions being thicker than the bridge in a top view, a size of each of the pair of holes being the same or less than the size of each of the terminals, the terminals inserted into the pair of holes by forced insertion wherein the bridge has gutters to be easily bent to adjust spaces between the holes of the connector.

2. The secondary battery module of claim 1, wherein the connector is welded to the terminals.
