Patent ID: 8879267

Claim:
A transceiver assembly comprising: a transceiver module comprising a housing, the housing having an outer surface, the outer surface having ribs extending therefrom, the transceiver module having a thermal interface member on the outer surface, the thermal interface member being positioned proximate the ribs; and a receptacle assembly comprising a guide frame having a receptacle receiving the transceiver module in a loading direction, the receptacle extending longitudinally along the loading direction, the receptacle assembly comprising a receptacle connector in the receptacle being electrically coupled with the transceiver module, the receptacle assembly comprising a heat sink and a clip coupling the heat sink to the guide frame, the heat sink having a heat sink surface facing the thermal interface member, the heat sink surface having a step extending from the heat sink surface, the step having a module engagement surface configured to be in direct thermal engagement with the thermal interface member; wherein the ribs ride along the step during insertion into and removal from the receptacle of the transceiver module, wherein when the ribs are longitudinally aligned with and engage the step, the module engagement surface is in an elevated position such that the engagement surface is spaced apart from the thermal interface member, and when the ribs are longitudinally offset from the step, the module engagement surface is in a recessed position, the module engagement surface being in direct thermal engagement with the thermal interface member in the recessed position.
