Patent ID: 8691429

Claim:
A battery pack assembly comprising: a rigid frame having an inner side that defines a first mounting location and an outer side that defines a second mounting location; a bare cell that is mounted within the rigid frame in the first mounting location, wherein the bare cell includes at least one electrode that extends towards the second mounting location; a protection circuit module having a first and a second side, wherein the protection circuit module includes at least one electrode lead that is positioned on the first side of the protection circuit module wherein the protection circuit module is mounted in the second mounting location of the frame and wherein the at least one electrode of the bare cell is electrically connected to the at least one electrode lead of the protection circuit module and wherein the protection circuit module and the second mounting location of the frame include a projecting member that extends substantially perpendicularly between the first side of the protection circuit module and the second mounting location and a receptacle formed on an outer lateral edge of the protection circuit module or the second mounting location of the frame that receives the projecting member to retain the protection circuit module on the second mounting location; and a cover that is positioned so as to cover the protection circuit module and wherein the cover engages with the second mounting location of the frame so as to retain the cover adjacent the outer side of the frame wherein the second mounting location of the frame defines a protrusion and the cover defines a recess that is sized and shaped to receive the protrusion so as to maintain the cover in contact with the frame wherein the protrusion extends in the same direction as the projecting member.
