Abstract
An electrical connection structure, and a secondary battery pack using the same are disclosed. The structure comprises an electrical connection member which includes an insulating body for insulating a PCM from a battery cell, and cathode and anode leads mounted on the insulating body in a state of being electrically insulated from each other. One or both of the cathode and anode leads are welded to associated electrode terminals of the battery cell. The cathode and anode leads are connected in a contact state to associated electrode taps of the PCM when engaging the PCM to the battery cell. The connection structure allows only the electrode leads to be welded to the battery cell, and allows the electrode terminals to be connected to the electrode taps through contact without an additional welding operation, thereby remarkably reducing the number of assembling steps, lowering manufacturing costs and preventing malfunction.
