Abstract:
1. A connecting member used to electrically connect electrode terminals of unit cells constituting a secondary battery module with each other, the connecting member comprising: a first terminal connecting body connected to the electrode terminal of one unit cell (a); a second terminal connecting body connected to the electrode terminal of another unit cell (b); and an insulating member mounted between electrode terminals of the neighboring unit cells for accomplishing the electrical insulation between the electrode terminals, the insulating member being coupled to the electrode terminals, wherein the first terminal connecting body and the second terminal connecting body are separated from each other while the first terminal connecting body and the second terminal connecting body are connected to the corresponding electrode terminals, and the electrical connection between the unit cell (a) and the unit cell (b) is accomplished by coupling a conductive member to the first terminal connecting body and the second terminal connecting body, wherein the first and second terminal connecting bodies of the connecting member are electrically connected to the electrode terminals of the corresponding unit cells while the first and second terminal connecting bodies of the connecting member are coupled to the insulating member, wherein the insulating member comprises a first assembly unit body and a second assembly unit body constructed such that the assembly unit bodies can be coupled with or separated from each other, a cathode terminal of the unit cell being coupled to one of the assembly unit bodies while an anode terminal of the unit cell is coupled to the other assembly unit body, wherein the first assembly unit body has a female coupling part formed at one side thereof, and the second assembly unit body has a male coupling part formed at one side thereof, the male coupling part corresponding to the female coupling part, wherein the first and second assembly unit bodies are provided at the side parts of the upper ends thereof with coupling protrusions, by which the first and second assembly unit bodies are coupled with another insulating member stacked on the first and second assembly unit bodies while the first and second assembly unit bodies are provided at the lower end surfaces thereof with coupling grooves, which correspond to the coupling protrusions, and wherein the second assembly unit body is provided at the side thereof with a hollow part, by which the connecting member is coupled to the insulating member constituted by the coupled first and second assembly unit bodies.
