Patent ID: 8329331

Claim:
A battery module comprising: a plurality of unit batteries each of the plurality of unit batteries comprising electrode terminals protruded from the unit batteries; a connecting member to which the electrode terminals from adjacent unit batteries are inserted, the connecting member comprising a first and a second fitting portions including a gap on one side of the fitting portions, the fitting portions receiving the electrode terminals wherein the fitting portions include an interior surface having a length substantially equal to the length of the electrode terminals and a plurality of straight parallel elastic protrusions of a first height that engage the electrode terminals and are positioned adjacent the interior surface of the fitting portions so as to extend the entire length of the interior surface at the first height and so that there is a gap between each of the protrusions and the interior surface of the fitting portion so that the elastic protrusions are deformable and a first and second connecting parts for connecting the first and second fitting portions while having the gap between the first and second connecting parts wherein the connecting member is formed of an electrical insulator and defines an interior surface; a first and a second conductive plates that define the interior surface of the fitting portions of the connecting member and a third conductive plate that extends between the first and second conductive plates so as to electrically interconnect the first and second conductive plates, wherein the first, second and third conductive plates are formed on the interior surfaces of the connecting member so as to be insulated by the connecting member; and a pressure member for compressing the first and second connecting parts so as to narrow the gap between the connecting parts.
