Electrical connector assembly with mated plug connector and receptacle connector

A plug connector for use with a receptacle connector having two rows of contacts, comprising:

• an insulative main body forming a mating tongue at a front end in a front-to-back direction;
• a flat flexible cable assembled into the main body and including on two opposite surfaces thereof a metallic reinforcement plate, and a plurality of conductors adapted for mechanically and electrically connecting respectively to one row of contacts for signal transmission during mating;
• a metallic support plate assembled to the main body to support the cable via mechanically and electrically connecting to the metallic reinforcement plate, and adapted for mechanically and electrically connecting to the other row of contacts for grounding during mating;
• and
• a presser assembled to the main body to press the flat flexible cable opposite to the metallic support plate in a vertical direction perpendicular to the front-to-back direction;
• wherein
• the metallic support plate is enclosed within the insulative main body except a front region of the metallic support plate being exposed upon the mating tongue in the vertical direction.

A receptacle connector for use with a plug connector equipped with a flat flexible cable having a plurality of conductor exposed upon one surface and a metallic reinforcement plate on an opposite surface, said receptacle connector comprising:

• an insulative housing;
• two rows of contacts retained in the housing, one row of contacts being unified together by a crossbar for electrically connecting with the reinforcement plate during mating, and the other row of contacts for mechanically and electrically connecting to the respective conductors during mating;
• a frame like metallic shell enclosing the housing;
• and
• a metallic cover discrete from the shell and attached upon the shell and shield a rear side of the housing;
• wherein
• a coupling is formed between the shell and the cover during assembling the cover to the shell, and said coupling is located adjacent to a pair of mounting legs which are mounted upon a printed circuit board on which the receptacle connector is seated.
