An electrical connector assembly comprises a plug connector (10) and a receptacle connector (15). The plug connector includes a plug housing (11) having a plug tail section (30) and a plug shroud section and at least one plug power contact (20). The receptacle connector includes a receptacle housing (16) having a receptacle tail section and a receptacle shroud section and at least one receptacle power contact (21). The plug connector (10) and the receptacle connector (15) are configured to mate with each other by insertion of the receptacle shroud section into the plug shroud section to establish an electrical connection between the plug power contact (20) and the receptacle power contact (21). The plug housing (11) includes at least one cooling slot (50) in the plug shroud section, and the receptacle housing (16) includes at least one cooling slot (50) in the receptacle shroud section that is aligned with the at least one cooling slot in the plug shroud section to enhance cooling airflow through the plug shroud section and the receptacle shroud section when the plug connector (10) and the receptacle connector (15) are mated.
