Patent number: 6775138Abstract: A heat sink clip (10) is shaped from a single piece of metal wire. Opposite ends of the metal wire are bent to form a generally twin strand structure that is the clip. The clip includes a central pressing portion (12), two resilient connecting portions (18) extending outwardly and upwardly from the pressing portion, and two arms (14) depending from distal ends of the connecting portions. The pressing portion has four contact points at a bottom thereof, for pressing a heat sink (20) onto a CPU (30). A pair of hooks (16, 16′) is inwardly formed from distal ends of the arms respectively, for engaging with a pair of retaining ears (42) at opposite sides of a CPU socket (40). The contact points of the pressing portion enable the heat sink to be securely fastened to the CPU mounted on the CPU socket.Type: GrantFiled: December 9, 2002Date of Patent: August 10, 2004Assignee: Hon Hai Precision Ind. Co., Ltd.Inventors: Hsieh Kun Lee, Wellint Xia, Toly Lee

Patent number: 6644387Abstract: A heat sink assembly includes a heat sink (20), a clip (40), and a spring clamp (60). The heat sink includes a base (21), pin fins (23), and slots (25, 27) defined between respective adjacent rows of the pins in perpendicular crisscross fashion. The clip made from a flexible metal wire includes a central body (41) with a raised portion (43), and two arms (45) extending perpendicularly but in different directions from opposite ends of the body. A hook (47) is formed at a free end of each arm. The spring clamp includes an elongate central pressing portion (61). A longitudinal opening (63) defined in the pressing portion engagingly receives the raised portion. Two pairs of elastically deformable wings (65) extend from respective opposite sides of the pressing portion. The clamp is resiliently retained in corresponding slots of the heat sink, and thus secures the clip to the heat sink.Type: GrantFiled: February 10, 2003Date of Patent: November 11, 2003Assignee: Hon Hai Precision Ind.

Publication number: 20020118512Abstract: A clip (10) securing a heat sink (20) to a heat-generating device (40) for removing heat therefrom comprises a body (12) and a pair of arms (14, 16) extending from the body. The body is positioned in a groove of the heat sink, for pressing the heat sink against a heat-generating device. The body integrally forms a loop (122) which receives a fin (24) of the heat sink, for enhancing engagement of the clip with the heat sink. Hooks (142, 162) at ends of the arms engage with holes defining in a substrate (30) on which the heat-generating device is mounted, thereby securing the heat sink against the heat-generating device.Type: ApplicationFiled: April 12, 2001Publication date: August 29, 2002Inventors: Hsieh Kun Lee, Wellint Xia
