Abstract
A heat sink clip (10) is shaped from a single piece of metal wire. Opposite ends of the metal wire are bent to form a generally twin strand structure that is the clip. The clip includes a central pressing portion (12), two resilient connecting portions (18) extending outwardly and upwardly from the pressing portion, and two arms (14) depending from distal ends of the connecting portions. The pressing portion has four contact points at a bottom thereof, for pressing a heat sink (20) onto a CPU (30). A pair of hooks (16, 16′) is inwardly formed from distal ends of the arms respectively, for engaging with a pair of retaining ears (42) at opposite sides of a CPU socket (40). The contact points of the pressing portion enable the heat sink to be securely fastened to the CPU mounted on the CPU socket.
