Abstract

A receptacle connection assembly includes a printed circuit board defining two spaced slots in a front edge portion with a mating tongue formed therebetween, a plurality of pads formed on two opposite surfaces of the mating tongue in a diagonally symmetrical manner for a flippable usage and a metallic shield including a tubular capsular portion assembled to the PCB to enclose the mating tongue.

Claims

1. A receptacle connector comprising:

a terminal module defining a rear base and a mating tongue extending forwards from the rear base and two rows of contacts;

a metallic shielding plate embedded within the mating tongue with two opposite side locking notches exposed to the mating tongue;

the contacts comprising plate contacting sections located upon opposite surface of the mating tongue and tails located upon a rear edge region of the rear base;

a capsular metallic shield surrounding the terminal module and the mating tongue extending into metallic shield;

a plurality of micro-coaxial cables located behind the terminal module and comprising inner conductors soldered with the tails of the contacts.

2. The receptacle connector as claimed in claim 1, further comprising a grounding bar located at the rear edge region of rear base of the terminal module and soldered to braiding layers of the corresponding micro-coaxial cables.

3. The receptacle connector as claimed in claim 2, wherein said grounding bar is essentially exposed upon two opposite surfaces of the rear edge region.

4. The receptacle connector as claimed in claim 1, further comprising a metallic bracket secured with the metallic shield and defining a rear wall with a window through which the micro-coaxial cables extend.

5. The receptacle connector as claimed in claim 4, wherein said bracket has a pair of mounting portions for mounting to an external part.

6. The receptacle connector as claimed in claim 1, comprising a rubber or silicon outer seal which is located upon a circumferential exterior surface of the shield around a front edge region thereof.

7. The receptacle connector as claimed in claim 1, comprising a silicon inner seal covers the rear base of the terminal module to not only seal the tails of the contacts but also cover a gap between the metallic shield and the terminal module.

8. A receptacle connector comprising:

a terminal module essentially of an insulative housing with two rows of contacts therein, said housing forming a rear base and a mating tongue, each of said contacts including a front contacting section exposed upon a corresponding surface of the mating tongue, a rear tail section;

the mating tongue defining a root portion near to the rear base and the root portion being thicker than a front portion of the mating tongue;

a metallic shield enclosing said terminal module;

a silicon inner seal, wherein the inner seal covers the rear base of the terminal module to seal a gap between the metallic shield and the terminal module; and

a rubber or silicon outer seal, wherein the outer seal is located upon a circumferential exterior surface of the metallic shield around a front edge region thereof.

9. The receptacle connector as claimed in claim 8, wherein a plurality of cables are electrically and mechanically directly connected the rear tail sections, a grounding bar is located around the rear tail sections of said terminals to be electrically and mechanically directly connected to braiding layers of the corresponding wire, respectively.

10. The receptacle connector as claimed in claim 8, further including a metallic bracket mounted upon the shield and having mounting portions for mounting to an external part.

11. The receptacle connector as claimed in claim 10, wherein said bracket further forms a window through which said wires extend rearwardly.

12. The receptacle connector as claimed in claim 11, wherein said mounting portions are located by two lateral sides of the shield.

18. The receptacle connector as claimed in claim 8, further including a metallic shielding plate embedded within the mating tongue with legs extending downwardly for mounting to the printed circuit board, said shielding plate forming a pair of locking notches in two opposite lateral sides of the mating tongue for engagement with a pair of locking heads of a latch of a complementary plug connector.

19. The receptacle connector as claimed in claim 18, wherein said shielding plate includes a pair of legs mechanically and electrically connected to the metallic shield.

13. A receptacle connector comprising:

a terminal module defining a rear base, a mating tongue extending forwards from the rear base and a cable supporting portion extending rearwards from the rear base, the mating tongue defining a root portion near to the rear base and the root portion being thicker than a front portion of the mating tongue;

two rows of contacts comprising contacting sections located upon opposite surface of the mating tongue and tails located upon the cable supporting portion;

a capsular metallic shield surrounding the terminal module and the mating tongue extending into metallic shield;

a plurality of micro-coaxial cables located behind the terminal module and comprising inner conductors disposed upon the cable supporting portion and soldered with the tails of the contacts.

14. The receptacle connector as claimed in claim 13, comprising a silicon inner seal, wherein the inner seal covers the rear base of the terminal module to seal a gap between the metallic shield and the terminal module.

15. The receptacle connector as claimed in claim 13, comprising a rubber or silicon outer seal, wherein the outer seal is located upon a circumferential exterior surface of the capsular metallic shield around a front edge region thereof.

16. The receptacle connector as claimed in claim 13, comprising a grounding bar, wherein the grounding bar is essentially exposed upon two opposite surfaces of the cable supporting portion, the grounding bar are welded directly with braiding layers of the corresponding wire, respectively.

17. The receptacle connector as claimed in claim 13, further comprising a metallic bracket secured with the metallic shield, wherein the metallic bracket defines a rear wall with a window through which the micro-coaxial cables extend.

20. The receptacle connector as claimed in claim 13, further including a metallic shielding plate embedded within the mating tongue with two opposite side locking notches exposed to the mating tongue.
