The plug connector includes two terminal supporting walls or platforms extending outwardly from the housing with terminal contact portions positioned in channels on the terminal support platforms. Each platform includes at an end thereof a groove which receives a grounding strip in the form of a drain wire, commoned to an outer shielding shell. The receptacle connector has an insulating housing having two elongate slots thereacross, adapted for receiving the terminal support walls of the plug connector, and receptacle contacts for mating engagement with the plug connector terminals.
