Abstract

A receptacle connector includes an insulating housing including a base and a mating tongue extending from the base and the mating tongue defining a thicken step portion at a root near to the base, two rows of contacts with contacting section exposing to opposite surfaces of the mating tongue in front of the step portion and tail sections extending out of the base, and a pair of separate metallic collars respectively disposed upon the opposite surface of the step portion. Two opposite ends of each metallic collar are embedded in the step portion of the insulating housing via an inserting mold process.

Claims

1. A receptacle connector, comprising:

an insulating housing comprising a base and a mating tongue extending from the base, the mating tongue defining a thickened step portion at a root near to the base;

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

a pair of separate metallic collars respectively disposed upon the opposite surfaces of the step portion;

wherein two opposite ends of each metallic collar are embedded in the step portion of the insulating housing via an insert molding process.

2. The receptacle as claimed in claim 1, comprising a shielding plate, wherein the shielding plate defines a pair of locking side edges for locking with corresponding latches of a corresponding plug connector, the pair of locking side edge is in front of the opposite ends of the collars.

3. The receptacle as claimed in claim 2, wherein each collar defines retention lugs at opposite ends thereof which bend toward the shielding plate and are embedded in the step portion.

4. The receptacle as claimed in claim 3, wherein each retention lug includes a first lug with a half-circle notch at a free end of the first lug and a second lug shorter than the first lug.

5. The receptacle as claimed in claim 3, wherein the shielding plate defines two notches along a side-projecting portion of each lateral side thereof, the first lugs of the pair of the retention lugs are received in the notches.

6. The receptacle as claimed in claim 1, wherein the mating tongue includes a front section and a rear section, the front section shares a same boundary molding line with the rear section.

7. The receptacle connector as claimed in claim 1, wherein the step portion has a front portion located in front of the collars to resist the collars and the front portion.

8. The receptacle connector as claimed in claim 7, wherein the front portion has a front tilt face and a horizontal face flush with the collars.

9. The receptacle connector as claimed in claim 1, wherein each collar further forms a vertical extension in the front face of the base.

10. The receptacle connector as claimed in claim 9, wherein the vertical extension defines a pair of through holes therein.

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

an insulating housing defining a base and a mating tongue forwardly extending therefrom in a front-to-back direction with a thicken step structure formed around a root thereof in transverse direction and a vertical direction perpendicular to the front-to-back direction, the mating tongue defining upper and lower surfaces thereof;

a row of upper contacts and a row of lower contacts disposed in the insulative housing with contacting sections exposed upon the upper and lower surfaces of the mating tongue respectively;

a shielding plate embedded in the mating tongue and the base, the shielding plate defines a pair of lateral locking side edges, and

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

wherein a rear wall of the metallic shield covers a back side of a lower portion of the base of the insulative housing so as to efficiently prevent EMI which invades through the mating cavity from rearwardly entering an interior around the printed circuit board.

12. The receptacle connector as claimed in claim 11, wherein the rear wall unitarily extends from the metallic shield.

13. The receptacle connector as claimed in claim 11, wherein the rear wall is separated from the metallic shield and made from an EMI (Electro-Magnetic Interference) gasket.

14. The receptacle connector as claimed in claim 11, wherein the receptacle connector comprises an upper bracket, the upper bracket includes a rear wall covering a back side of an upper portion of the base of the insulating housing so as to shield EMI above the printed circuit board along the front-to-back direction.

15. The receptacle connector as claimed in claim 11, wherein the rear wall of the upper bracket includes a plurality of tabs electrically and mechanically connected to corresponding pads on the printed circuit board.

16. A receptacle connector, comprising:

an insulating housing defining a base and a mating tongue forwardly extending therefrom in a front-to-back direction with a thickened step structure formed around a root thereof in transverse direction and a vertical direction perpendicular to the front-to-back direction, the mating tongue defining upper and lower surfaces thereof;

a row of upper contacts and a row of lower contacts disposed in the insulating housing with contacting sections exposed upon the upper and lower surfaces of the mating tongue respectively;

a shielding plate embedded in the mating tongue and the base, the shielding plate defines a pair of lateral locking side edges, and

a metallic shield retained on the base and surrounding the mating tongue to define a mating cavity around the metallic shield and the mating tongue, the mating cavity is for mating with a plug connector in a flippable manner;

wherein the metallic shield has no slits thereon.

17. The receptacle connector as claimed in claim 16, wherein the metallic shield is equipped with flared flanges for easy mating with the plug connector.

18. The receptacle connector as claimed in claim 16, wherein the receptacle connector comprises an upper bracket, the upper bracket is attached on the metallic shield and includes mounting legs for mounting to a printed circuit board on which the receptacle connector is seated.
