Patent ID: 7142428

Claim:
A heatsink device in combination with a circuit board, the heatsink device comprising: laterally opposing sidewalls coupled to a horizontal portion defining an interior compartment, a heat conductive body including a plurality of laterally disposed movable clamp members within the interior compartment and depending away from the horizontal portion, the clamp members defining a plurality of apertures with respect to the sidewalls for receiving at least one power device therein, and the heat conductive body including an activation aperture responsive to a linear movement therein so as to provide a locking force to the at least one power device; wherein a locking activation member has a first portion configured to extend through an aperture in a circuit board for operatively engaging the activation aperture and to provide the linear movement and a second portion of the locking activation member is configured to conduct heat away from the at least one power device via the aperture.
