CONNECTION STRUCTURE FOR A SECONDARY BATTERY AND BATTERY PACK COMPRISING SAME

摘要

Disclosed are a connection structure for a secondary battery, and a battery pack comprising same. The connection structure for a secondary battery according to the present invention electrically interconnects: a core pack, which electrically connects two or more unit cells; the unit cells of the core pack; and a protective circuit module formed of a PCB. The connection structure comprises: a metal plate having an electrode connection unit connected to electrodes of each unit cell of the core pack, and a circuit connection unit connected to the protective circuit module; and a circuit terminal unit which is located in a connection opening formed in the PCB of the protective circuit module such that the connection opening connects the upper surface and the lower surface of the PCB, and which is electrically connected to the circuit connection unit. The circuit connection unit is electrically connected to the circuit terminal unit in a physically connective manner enabling a selection of connection or separation.
