ABSTRACT:
A clip (30) for securing a heat sink (40) to an electronic device (52) includes a pin (32) and a pressing member (34), each of which are integrally formed by stamping sheet metal. The pin includes a cylindrical body having a vertical notch (321), a pair of symmetrically opposite latches (323) depending from the cylindrical body to enable the pin to elastically deform, and a pair of barbs (325) extending outwardly and slightly upwardly from bottom ends of the latches respectively. The pressing member includes a circular body (341), a column (347) depending from the circular body, and a pair of spring arms (343) extending outwardly and downwardly from opposite sides of the circular body. A distal end of each spring arm is bent inwardly and upwardly to form an elbow portion (345). An opening (349) is defined through the circular body and the column, for receiving the pin.
