Abstract
A retaining clamp device (10) for use with a heat sink (40) of the CPU (50) unit includes a clip (12) and an associated spring (30) attached to the clip (12) wherein the clip (12) includes an elongated main body (14) with a pair of locking tags (18) downward extending at two opposite ends thereof to respectively cooperate with the lugs (62) on the side walls (64) of the socket (60) under the CPU (50) for latching the retaining clamp device (10) unto the CPU (50) set while the spring (30) is in a wave-like form and positioned between the main body (14) of the clip (12) and the top surface (48) of the heat sink (40) so as to exert the sufficient biasing force firmly pressing the heat sink (40) against the CPU (50) for efficient heat transfer thereof, by means of its deformation derived from the less space/height between the main body (14) of the clip (12) and the top surface (48) of the heat sink (40) in comparison with the original height of the spring (30).
