发明名称 BATTERY PACK
摘要 A battery pack is provided to electrically connect a unit cell and a circuit board without the influence of minuteness of connector parts and facing interval between terminals. A battery pack is arranged with a circuit board(3) mounted with a protection circuit controlling the charge and discharge current, inside the outer cover arranged at the upper end of unit cell(1). Positive/negative electrode terminals(8,9) formed at the upper side of the unit cell, and the positive/negative electrode terminals(18,19) formed on the surface of the circuit board facing the unit cell are electrically connected with a connector(23). The connector is elastic body formed by molding the elastic materials in a polyhedral shape, and at least upper side and lower side are electrically connected. The upper side and lower side of the connector are pressure-welded between the unit cell and the positive/negative electrode terminals facing the circuit board.
