Claim Text:
1. An electrical connector assembly comprising: a plug connector defining an external mating tongue with two opposite first and second surfaces thereon; a plurality of first conductors formed on the first surface; a plurality of second conductors formed on the second surface; both said first conductor and said second conductor categorized with at least power pads, differential pads and grounding pads; wherein the mating tongue defines a pair of notches with corresponding conductor portions therein for both electrical connection and mechanical retention; a receptacle connector defining an insulative housing with a receiving cavity therein, wherein two rows of contacts are disposed respectively upon an upper interior surface and a bottom interior surface, and a pair of power contacts are respectively located on two opposite lateral side interior surfaces for coupling to the corresponding conductor portions in the corresponding notches; wherein the mating tongue defines a pair of raised ribs formed on two opposite side region of each of the opposite surface thereof, wherein a first vertical dimension is defined between the opposite surface on an area with the pair of ribs thereon, and a second vertical dimension is defined on another area without the pair of ribs thereon, said second vertical dimension being smaller than the first vertical dimension; and the receptacle connector defines a pair of slots formed in the housing beside each of the opposite upper and bottom sides and adjacent to two opposite lateral sides thereof, wherein during mating, the mating tongue is received in the receiving cavity and the raised ribs are received in the corresponding slots with the contacts coupled to the corresponding conductors, respectively; a different type receptacle connector defining another receiving cavity with a transverse direction larger that that of the mating tongue, and a third vertical dimension between the first vertical dimension and the second dimension, so that the pair of ribs prevent the mating tongue from being inserted into said another cavity.
