Apparatus for mounting CPU heat dissipator

Claim 1

An apparatus for mounting a CPU heat dissipator comprising a rigid plate, a pressing plate and a snapping plate, wherein; one part of both the rigid plate and the pressing plate is bent upward with an angle and another part of the rigid plate is reversely bent inward, hence providing an inclined surface; another part of a side plate of the rigid plate has another part bent downward through an angle, hence providing with a hole adapted for engaging with a bark on a ZIF socket; at one end of the upward bending part of the pressing plate, which is reversely bent inward for providing an inclined surface and an annular opening formed at one end of a slot, which is provided at the center of the pressing plate for connecting with an opening of a positioning recess are for providing a recovering force for preventing the deformation of the pressing plate when the snapping plate is inserted into the positioning recess; a plane surface formed on top of the snapping plate is used as the place where external force applies when combined with other elements (for example: the ZIF socket), and a hole provided therein is used as the place where small hand tools applies; both sides of the snapping plate are provided with a recess for tightly engaging with the positioning recess of the pressing plate; at the bottom of the snapping plate, an opening is formed for hooking up with the bark of the ZIF socket; a non-finned area having the width corresponding to that of a fin is formed within the heat dissipator which provides a plurality of projections facing the center of the non-finned area for tightly engaging with the rigid plate and the pressing plate.
