Abstract
A clip assembly comprises a body and a pair of separate fasteners. The body comprises a base for engaging with a heat sink, a pair of arms extending from opposite diagonal corners of the base, and a pair of end portions formed on free ends of the arms. An elliptical clearance hole is defined in each end portion for allowing movement of the fastener therein during engagement with a corresponding engaging hole of a printed circuit board. A pair of arcuate surfaces is formed proximate opposite transverse sides of each clearance hole. Each fastener comprises an intermediate main portion, and a head and an engaging portion formed on opposite ends of the main portion. The head has a transition section for engaging with the arcuate surfaces of the body to ensure vertical linear movement of the fastener during engagement with the corresponding engaging hole.
