Abstract

A receptacle connector includes: a housing including a base and a mating tongue in front of the base, the mating tongue defining a thickened portion at a root to the base, the mating tongue defining a pair of lateral locking sides; two rows of contacts with contacting section exposing to opposite surfaces of the mating tongue in front of the thickened portion and tail sections extending out of the base; and a metallic shield retained on the base and surrounding the mating tongue to define a mating cavity among the shield and the mating tongue. The shield is formed via a deep drawing process.

Claims

1. A receptacle connector, comprising:

a housing comprising a base and a mating tongue in front of the base, the mating tongue defining a thickened portion at a root to the base, the mating tongue defining a pair of lateral locking sides;

two rows of contacts with contacting section exposing to opposite surfaces of the mating tongue in front of the thickened portion and tail sections extending out of the base; and

a metallic shield retained on the base and surrounding the mating tongue to define a mating cavity among the shield and the mating tongue;

wherein the metallic shield is formed via a deep drawing process.

2. The receptacle connector as claimed in claim 1, comprising a metallic bracket, wherein the metallic bracket is fitly retained on the metallic shield.

3. The receptacle connector as claimed in claim 1, comprising a shielding plate, wherein the shielding plate defines a pair of locking side edges corresponding to the locking sides of the mating tongue.

4. The receptacle connector as claimed in claim 3, wherein the shielding plate defines two notches along a side-projecting portion of each locking side edge thereof.

5. The receptacle connector as claimed in claim 1, comprising two metallic collars, wherein the metallic collars at least partly covering the opposite surfaces of the thickened portion.

6. A receptacle connector adapted for mounting on a printed circuit board, comprising:

a housing defining a base and a mating tongue forwardly extending the base with a thickened portion formed around a root thereof, the mating tongue defining a first surface and a second surface thereof;

a row of first contacts and a row of second contacts disposed in the housing with contacting sections exposed upon the first and second surfaces of the mating tongue respectively, each row is categorized with grounding contacts, power contacts and signal contacts;

a shielding plate embedded in the mating tongue and the base, the shielding plate defines a pair of side-projecting locking portions near to a front edge thereof;

wherein the shielding plate defines a large cutout through the front edge thereof and a pair of small through openings at opposite sides of the large cutout, and at least a center opening behind the large cutout;

viewed in a vertical direction perpendicular to the mating tongue, front distal ends of the grounding contacts overlap the corresponding small through openings so as to benefit flow of an insulative material during forming process.

7. The receptacle connector as claimed in claim 6, wherein the small through opening is of an L-shape.

8. The receptacle connector as claimed in claim 6, wherein a one-piece collar is provided to surround the first surface and second surface of the thickened portion.

9. The receptacle connector as claimed in claim 8, wherein two retention plates extend from a same side of the collar and touch an inside of a metallic shield surrounding the housing.
