Abstract
A clip assembly (30) includes a nail member (40), a sleeve member (60), and a spring (50) around the sleeve member. The nail member includes a cap (42), a post (44), a neck (46) and a cone-shaped barb (48). A pair of wedges (442) is formed on an outer surface of the post. The sleeve member is cylindrical. The sleeve member defines a central bore (62) for receiving the nail member, and a pair of rectangular slots (66) for receiving the wedges. A circumferential shoulder (68) is formed on the sleeve member, for abutting against a bottom surface of a heat sink. A lower portion (72) of the sleeve member defines cutouts (722), thereby also forming deformable fingers (723). The sleeve member is interposed between the heat sink and a PCB. The nail member is inserted down through the lower portion, and elastically expands the fingers of the sleeve member.
