High frequency electrical connector assembly

An electrical connector assembly, comprising:

• a receptacle including inner and outer conductive shells, the inner conductive shell supporting at least one socket contact therein, each of the inner and outer conductive shells having a front end for mating with a mating connector and a back end configured to electrically connect to a printed circuit board, and the receptacle including a receptacle primary ground connection and a receptacle secondary ground connection;
• and
• a plug including an outer conductive shell supporting at least one pin contact configured to mate with the at least one socket contact of the receptacle, the outer conductive shell of the plug having a front end for mating with the front end of the receptacle, and a back end configured to electrically connect to a coaxial cable, and the plug including a plug primary connection and a plug secondary ground connection,
• wherein when the receptacle and plug are mated, the receptacle and plug primary ground connections form a primary grounding path through the assembly and the receptacle and plug secondary ground connections form a secondary grounding path through the assembly, thereby electrically connecting the plug and the printed circuit board.

An electrical connector assembly, comprising:

• a receptacle including an outer shell, the outer shell supporting at least one socket contact therein, the outer shell having a front end for mating with a mating connector and a back end configured to electrically connect to a printed circuit board, and the receptacle including one or more receptacle ground connections;
• and
• a plug including an outer shell supporting at least one pin contact configured to mate with the at least one socket contact of the receptacle, the outer shell of the plug having a front end for mating with the front end of the receptacle, and a back end configured to electrically connect to a coaxial cable, and the plug including one or more plug ground connections,
• wherein when the receptacle and plug are mated, the receptacle and plug ground connections form one or more grounding paths through the electrical connector assembly, thereby electrically connecting the plug to the printed circuit board, and
• wherein one of the receptacle ground connections with one of the plug ground connections are configured to mechanically engage the front ends of the receptacle and plug with one another.
