Socket connector having a thermally conductive insert

A socket connector comprises a housing having a mating end and a mounting end. The housing has a receptacle at the mating end configured to receive an electronic module therein, and the mounting end of the housing is configured to be mounted to a circuit board. Contacts are held by the housing. The contacts have mating ends exposed within the receptacle for mating with the electronic module, and the contacts having mounting ends extending from the housing for terminating to the circuit board. A thermally conductive insert is held by the housing and is positioned to thermally engage the circuit board when the housing is mounted to the circuit board. The thermally conductive insert has a module engagement interface positioned to thermally engage the electronic module when the electronic module is loaded into the receptacle, wherein the thermally conductive insert transfers heat from the electronic module to the circuit board.
