  • Patent number: 8004845
    Abstract: A fastening assembly used for securing a heat dissipation device to a printed circuit board, comprises a sleeve, an inserting device extending through the sleeve, a spring encircling the inserting device and received in the sleeve, and a supporting device inserted in the sleeve. The inserting device engages with a back plate below the printed circuit board. The sleeve is integrally formed of plastic and comprises a hollow body, a resilient portion extending from an outer surface of the body and pressing a bottom of the heat dissipation device upwardly, and four supporting portions extending from the outer surface of the body and pressing a top of the heat dissipation device downwardly. The supporting device is inserted between the body and the resilient portion, and abuts against the resilient portion, to thereby reliably keep the resilient portion at its locked position.

  • Patent number: 7974098
    Abstract: A heat-dissipating mechanism with a thermo-conducting sheet is arranged between a pluggable optical transceiver and a heat sink. One of the optical transceiver and the heat sink includes the thermo-conducting sheet. The heat sink is assembled with a cage to be movable vertically and against a downward force. The optical transceiver includes a projection that comes in contact with the heat sink. The heat sink includes a rail with a pocket. When the transceiver is inserted into the cage, the projection first runs along the rail to lift the heat sink upward; subsequently, the projection is set within the pocket to allow the thermo-conducting sheet to contact the transceiver.
