Patent ID: 8691410

Claim:
A battery pack, the battery pack comprising: a secondary battery having a case and a first planar surface with a first terminal formed on the first planar surface; and a safety member in electrical communication with the secondary battery, the safety member comprising: an insulating holder having a first surface and a second surface that defines a recess wherein the first surface of the insulating holder is positioned proximate the first planar surface of the secondary battery case; a thermal safety device comprising a body and first and second lead plates extending from the body, wherein the thermal safety device is mounted within the insulating holder so that the first and second lead plates are positioned within the recess of the insulating older adjacent the second surface of the insulating holder and so that the insulating holder is interposed between both the first and second lead plates of the thermal safety device and the first planar surface of the secondary battery case and so that the thermal safety device is in electrical communication with the first terminal via the first lead plate; and a conductive plate mounted to the insulating holder and in electrical communication with the thermal safety device via the second lead plate wherein the conductive plate is sized to fit within the recess of the insulating holder and be retained therein.
