Connector with integrated heat sink
A receptacle connector defines a port. The port is provided with spring fingers that are configured to engage a mating module. The spring fingers are thermally coupled to a heat transfer plate that can be configured to provide part of a cage that defines the port. Fins can be mounted on or integrated into the heat transfer plate. In operation, thermal energy from an inserted module is transferred from the module to spring fingers and then to the heat transfer plate and then to a thermal dissipation system.
1. A connector, comprising:
a cage that defines a first port and a second port, the cage configured to be supported by a circuit board, the first and second ports being vertically stacked relative to the supporting circuit board, and the first and second ports each having four walls;
a plurality of spring finger plates, each spring finger plate forming a wall of each of the first and second ports and supporting a plurality of spring fingers, the plurality of spring fingers configured to engage a module inserted into one of the first and second ports in a first direction, the spring fingers configured to translate in a second direction, in operation, when the module is inserted into one of the first and second ports, wherein each spring finger of the plurality of spring fingers is configured to individually contact the module inserted into one of the first and second ports; and
at least one heat transfer plate in thermal communication with a spring finger plate of the plurality of spring finger plates.
2. The connector of claim 1 , wherein the spring finger plate in thermal communication with the at least one heat transfer plate is soldered to the at least one heat transfer plate.
3. The connector of claim 1 , wherein the spring finger plate in thermal communication with the at least one heat transfer plate is attached to the at least one heat transfer plate with a thermally conductive adhesive.
4. The connector of claim 1 , wherein each of the spring finger plates forming a wall of the first port are in thermal communication with spring finger plates forming adjacent walls of the first port.
5. The connector of claim 1 , wherein the plurality of spring finger plates comprise four spring finger plates forming the four walls of the first port and four spring finger plates forming the four walls of the second port.
