Mechanism to make a heat sink in contact with a pluggable transceiver, a pluggable optical transceiver and a cage assembly providing the same

摘要

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.
