Plug and receptacle assembly having a thermally conductive interface

Plug assembly including a pluggable connector having a mating end and a trailing end and a central axis extending therebetween. The pluggable connector includes internal electronics that generate thermal energy within the pluggable connector. The mating end is configured to engage a data connector. The pluggable connector also includes a thermal interface region that is coupled to the pluggable connector. The thermal interface region includes a series of transfer plates that extend parallel to each other and to the central axis. The transfer plates define a series of plate-receiving slots extending parallel to the central axis. The thermal interface region transfers the thermal energy generated by the internal electronics through the transfer plates.
