Electrical connector assembly having grounding buses

摘要

An electrical connector assembly includes a receptacle connector and a mating plug connector. The receptacle connector has an insulative housing forming two elongate sidewalls mounting a plurality of signal terminals therein. An internal wall defining a plurality of grooves for receiving a plurality of first ground buses therein is formed at the center of the insulative housing. The plug connector has a dielectric housing with a base and two rows of tongues extending upward from the base. A plurality of passageways is defined in an outer side surface of each tongue with signal contacts received therein for electrically connecting with the signal terminals of the receptacle connector. A plurality of grooves is defined in an inner side surface of each tongue with a plurality of second ground buses received therein for engaging with the first ground buses of the receptacle connector.
