Abstract

This invention relates to a fastener for a heat sink, comprising a substrate on which the heat sink is disposed and a plurality of fastening members for securing the substrate to a circuit board. Each fastening member has a shank base, a sleeve, a nut, and a threaded fastening member. The shank base penetrates the substrate and the circuit board. The sleeve has an open end encompassing one end of the shank base, a terminal end opposite to the open end, and a slot formed in the terminal end for fixing the nut. The threaded fastening member penetrates through the shank base and the open end and the slot of the sleeve and engages the nut. With the arrangement of coupling of the shank base and the sleeve, loosening between the threaded fastening member and the nut may be alleviated and thus, separation of the heat sink from the heating element on the circuit board may be prevented so as to ensure the heat dissipating efficiency of the heating element.
