Abstract

A heat sink assembly includes a heat sink (30), a clip (20), and a fastener (10). The heat sink has a base (301) and a plurality of parallel fins (302) extending therefrom. A pair of barbs (303) is symmetrically formed on outmost sides of two adjacent central fins. The fastener includes a basal body (101), a pair of side arms (103) extending upwardly from the body, a pair of pressing plates (104) extending horizontally outwardly from top ends of the side arms, a pair of locking arms (105) depending from the pressing plates, and a pair of catches (106) inwardly formed at distal ends of the locking arms for engaging with the barbs of the heat sink. A notch (102) is defined in a bottom of the body, for facilitating the fastener abutting against a pressing section (201) of the clip.
