Abstract
An active electrical connection system includes a first connector, a second connector for releasably connecting with the first connector, active circuitry for affecting a data signal, and a heat sink for dissipating heat. A heat sink positioning system comprising a plurality of protrusions and corresponding recesses precisely positions the heat sink during insertion to prevent sliding contact with a thermal interface material applied between the heat sink and a plug.
Claims15
An active electrical connection system, comprising:
- a first connector including a plug;
- a second connector including a socket configured for receiving the plug to a connected position within the socket;
- active signal processing circuitry in electronic communication with one or both of the first and second connectors for processing a data signal transmitted between the first and second connector;
- a heat sink including a heat sink base secured to the second connector in a position for sliding engagement with the plug at a mechanical interface between the base and the plug as the plug is moved to the connected position within the socket;
- and
- a plurality of corresponding protrusions and recesses at the mechanical interface between the base and the plug, including protrusions on one of the heat sink base and the plug and recesses on the other of the base and the plug, wherein the protrusions are vertically misaligned with the corresponding recesses upon initial entry of the plug into the socket to urge the heat sink away from the plug, and wherein the recesses are vertically aligned with the protrusions to receive the protrusions when the plug reaches the connected position.
