Patent ID: 8828592

Claim:
A battery pack, comprising: a bare cell comprising an outer surface including a coupling groove; a protection circuit electrically coupled to the bare cell and comprising a surface facing the outer surface of the bare cell; a coupler electrically coupled between the bare cell and the protection circuit, the coupler comprising a first region including a first surface facing and attached to the surface of the protection circuit, a third region defining a coupling hole and including a second surface contacting the bare cell, and a second region between and generally perpendicular to the first region and the third region; a fastener adapted to couple to the coupling groove through the coupling hole; and an elastic pad between and contacting the surface of the protection circuit and the outer surface of the bare cell, the elastic pad and the coupler each having a same height equal to a distance between the surface of the protection circuit and the outer surface of the bare cell, wherein the third region of the coupler comprises an elastic region for elastically supporting the fastener and the bare cell.
