Patent ID: 8623542

Claim:
A protection circuit module (PCM) including a protection circuit for controlling overcharge, overdischarge, and overcunent of a battery, wherein a pair of connection members are attached to a bottom of the PCM, while the connection members are electrically connected to the protection circuit, the connection members being constructed by bending a sheet material into a predetermined shape, to form groove-shaped connection structures into which plate-shaped electrode terminals of a battery cell are inserted and coupled, and each of the connection members comprises: a lower connection plate coupled to a terminal connection part of a board having the protection circuit formed thereon (‘a protection circuit board’); a pair of rear extensions extending from opposite-side ends of a rear of the lower connection plate, while the rear extensions have a predetermined width in a longitudinal direction, on the basis of a direction in which the corresponding electrode terminal of the battery cell is inserted, the rear extensions being bent forward while being partially bent downward to press the inserted corresponding electrode terminal of the battery cell, the rear extensions being integrated at ends thereof to form an electrode terminal insertion part; and front extensions extending from opposite ends of a front of the lower connection plate, while the front extensions have a predetermined width in a lateral direction, to elastically press the electrode terminal insertion part formed by the rear extensions in a state in which the corresponding electrode terminal of the battery cell is inserted in the electrode terminal insertion part.
