Flippable electrical connector

An electrical connector assembly comprising:na 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.

An electrical connector assembly comprising:na first connector including:a first insulative housing defining therein a cavity forwardly communicating with an exterior along a front-to-back direction;upper and lower rows of first contacts disposed in the first housing along a transverse direction perpendicular to said front-to-back direction and respectively located by opposite upper and lower sides of the cavity in a vertical direction perpendicular to both said front-to-back direction, each of said contacts extending along the front-to-back direction;a pair of large deflectable contacts disposed in the first housing by two opposite lateral sides of the cavity in said transverse direction;a second connector matable with the first connector and including:na second insulative housing defining a mating tongue with opposite upper and lower surfaces thereon; opposite upper and lower rows of second contacts disposed in the second housing and exposed upon the upper and lower surfaces, respectively;a pair of conductor portions formed on two opposite lateral sides of the mating tongue; wherein each of the conductor portions defines a latching structure so as to latch the corresponding large deflectable contact when the mating tongue is received in the cavity during mating;said conductor portions are unitarily formed on two lateral sides of a U-shaped metallic plate;said U-shaped metallic plate transmit power and surrounds an internal printed circuit board on which the second contacts and a cable are mechanically and electrically connected.

An electrical connector comprising:nan upper terminal module including a plurality of upper contacts embedded within an upper insulator with corresponding contacting sections upwardly exposed to an exterior;a lower terminal module including a plurality of lower contacts embedded within a lower insulator with corresponding contacting sections downwardly exposed to the exterior;a metallic reinforcement plate sandwiched between the upper terminal module and the lower terminal module; whereinthe upper terminal module, the lower terminal module and the reinforcement plate commonly form a mating tongue, and the metallic reinforcement plate forms a pair of latching sections on two opposite lateral sides exposed outside of the mating tongue for respectively latching with a pair of deflectable retention pieces when said mating tongue is received within a cavity of a complementary connector;said mating tongue forms a pair of notches in two opposite lateral sides with the pair of latching sections exposed therein, respectively.
