  • Patent number: 6865083
    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.

  • Patent number: 6826054
    Abstract: A heat sink clip assembly is for attaching a heat sink (30) to a central processing unit (CPU) (41) mounted on a mother board (40), and includes a back plate (10), four posts (13) and four fasteners (20). Each fastener includes a bottom engaging end (27), a neck (25) received in a corresponding through hole (35) of the heat sink, a top cap (21) engaged on the neck, and a spring (23) disposed around the neck and seated on the heat sink. Each post includes a top threaded end (17), and an annular groove (15) receiving a plastic ring (50) therein. The posts extend upwardly from the back plate, and are engaged in the mother board. The engaging end of each fastener defines an internal threaded hole adjustably engaging with the threaded end of a corresponding post, thereby attaching the heat sink to the CPU with even clamping forces.

  • Patent number: 6707672
    Abstract: A heat sink clip assembly includes a clip (10) and a frame (50). The clip is formed from a single strand of resilient metallic material that is bent and coiled to become generally U-shaped. The clip includes a retaining bar (11), and two confining poles (12) extending perpendicularly from opposite ends of the retaining bar. Each confining pole comprises a first resilient section (14) near a distal end of the confining pole, a fastener (18) at the distal end of the confining pole, and a second resilient section (16) adjacent the retaining bar. Each first resilient section has a pressed head (142) with a handle (30) attached thereon. The frame comprises a plurality of locking fingers (52) extending perpendicularly from a flat rectangular board. Each locking finger has a hook (53, 54) for respectively locking the retaining bar or one of the fasteners of the clip.
