Abstract

A plug connector includes a mating tongue defining top and bottom surfaces thereon. Each surface is provided with a plurality of conductors in one row wherein the characters/categories of the conductors on the top surface are sequentially arranged to be same with those on the bottom surface with a pair of power conductors in two notches at two lateral side edges. The corresponding receptacle connector mounted upon a printed circuit board, defines a receiving cavity to receive the mating tongue therein. Opposite top and bottom rows of contacts are respectively located by upper and bottom sides of the receiving cavity and categorized essentially in a same sequence with the conductors of the plug connector for respectively connecting to the corresponding conductive pads, respectively. A pair of power contacts are located by two lateral sides of the receiving cavity to couple to the corresponding power conductor portions in the notches.

Claims

1. An electrical connector assembly comprising:

a plug connector including;

an insulative housing unit essentially having a pair of housings each equipped with a plurality of contacts thereof, each of said contacts defining a front contacting section and a rear tail section;

a paddle card sandwiched, in a vertical direction, between the pair of housings with circuit pads mechanically and electrically connected to the corresponding rear tail sections, respectively; and

a pair of metallic shells enclosing a rear portion of the housing unit but exposing a front portion of the housing unit to cooperate with a front region of the shell to be a mating tongue;

said mating tongue forms a pair of notches on two opposite lateral side edges, respectively, and

a pair of conductive segments located on the two opposite lateral side edges with locking regions exposed in the notches, respectively.

2. The electrical connector assembly as claimed in claim 1, wherein an overmolded cover encloses the pair of shells with a rearwardly extending cable which is connected to the paddle card.

3. The electrical connector assembly as claimed in claim 1, wherein the conductive segment is made of sheet metal defining a thickness thereof, and the thickness of the locking region extends transversely.

4. The electrical connector assembly as claimed in claim 3, wherein said pair of conductive segments are unitarily formed within a U-shaped structure which encloses front and opposite side edges of the paddle card.

5. The electrical connector assembly as claimed in claim 1, wherein the conductive segment is made from die-casting.

6. The electrical connector assembly as claimed in claim 1, further including a receptacle connector adapted to be mated with the plug connector, wherein said receptacle connector includes an insulative body enclosed in a metallic shield to define a mating cavity, two rows of contacts disposed in the housing and located by two sides of the mating cavity in said vertical direction with corresponding contacting sections exposed in the mating cavity, a pair of conductive pieces disposed in the housing by two sides of the mating cavity in a transverse direction perpendicular to said vertical direction to mate with the conductive segments of the plug connector in a locking manner.

7. The electrical connector assembly as claimed in claim 6, wherein the insulative housing of the receptacle connector is equipped with a metallic shielding plate behind the mating cavity to separate said two rows of contacts.

8. The electrical connector assembly as claimed in claim 7, wherein said shielding plate includes at least one spring tang mechanically and electrically connecting to one grounding contact of said contacts of the receptacle connector in the vertical direction.

9. The electrical connector assembly as claimed in claim 1, wherein said pair of conductive segments deliver power.

10. The electrical connector assembly as claimed in claim 1, wherein the pair of conductive segments are sandwiched between the pair of housings in said vertical direction.

11. An electrical connector assembly comprising:

a first electrical connector including;

an insulative housing defining a mating cavity with two rows of contacts disposed in corresponding passageways of the housing and by two sides of the mating cavity in a vertical direction, and with a pair of conductive pieces in the housing and by two sides of the mating cavity in a lateral direction perpendicular to said vertical direction, both said contacts and said conductive pieces being outwardly deflectable with regard to the mating cavity during mating, said contacts defining signal contacts and grounding contacts;
