Flippable electrical connector

A receptacle connector comprising:

• an insulating housing comprised a base and a mating tongue extending forwards from the base;
• a plurality of contacts comprising contacting sections exposed on the mating tongue, middle sections retained in the base and soldering legs extending beyond the base;
• and
• a metallic shell enclosing the insulating housing;
• wherein
• the metallic shell comprises a front region surrounding the mating tongue to defines a mating cavity among the mating tongue the front region into which a plug connector is inserted in either of two insertion orientations, a middle retention region encircled the base and confronting against a pair of rear protrusions and a rear region with a rear stopper to limit a rearward movement of the insulating housing.

A plug connector comprising:

• an insulative housing defining a receiving cavity;
• a plurality of plug contacts disposed in opposite sides of receiving cavity of the insulative housing,
• a metallic latch retained in the insulative housing and including a pair of resilient latching arms located in opposite lateral ends of the receiving cavity and protruding into the receiving cavity in a first direction;
• and
• a one-piece metallic EMI bracelet enclosing a front end region of an exterior surface of the insulative housing with a plurality of spring fingers protruding into the receiving cavity in a second direction perpendicular to the first direction.
