Abstract

A plug connector mateable with the receptacle connector, includes an insulative housing enclosed in a metallic shell, defining a receiving cavity to receive the mating tongue, and equipped with a plurality of contacts on opposite sides in the vertical direction. A latch forms a pair of locking heads extending into two opposite lateral sides of the receiving cavity to lock with a shielding plate embedded within a mating tongue of the complementary receptacle connector during mating.

Claims

1. A receptacle connector for use with a plug, comprising:

an insulative housing defining a base with a mating tongue forwardly extending therefrom along a front-to-back direction;

a plurality of contacts disposed in the housing with contacting sections exposed upon the mating tongue and categorized with signal contacts, power contacts and grounding contacts;

a metallic shell enclosing the housing to define a capsular mating cavity in which said mating tongue is disposed; and

a metallic shielding plate embedded within the mating tongue;

wherein the shielding plate defines a pair of rigid lateral edge sections without flexibility thereof, in a transverse direction perpendicular to said front-to-back direction, configured to be locked with a deflectable latch of the plug.

2. The receptacle connector as claimed in claim 1, further including a metallic bracket soldered to and at least partially surrounding the shield and equipped with mounting legs for mounting to a printed circuit board.

3. The receptacle connector as claimed in claim 2, wherein the bracket is located on a bottom side of the shield in a vertical direction perpendicular to both said front-to-back direction and said transverse direction.

4. The receptacle connector as claimed in claim 2, wherein the bracket is either softer or stiffer than the shield.

5. The receptacle connector as claimed in claim 2, wherein said bracket is located upon a top side of the shield and includes a pair of block like raised portions to cover two opposite lateral sides of the housing which is originally exposed via gaps of an extending plate of the shield.

6. The receptacle connector as claimed in claim 5, wherein said mounting legs extend downwardly from said pair of block like raised portions.

7. The receptacle connector as claimed in claim 2, wherein tails of the contacts are configured with a detachable compressing manner rather than a soldering manner.

8. The receptacle connector as claimed in claim 7 wherein the mounting legs are resilient and detachable with regard to the printed circuit board.

9. A plug connector for use with a complementary receptacle connector, comprising:

an insulative housing enclosed in the metallic shell and defining a receiving cavity forwardly communicating with an exterior in a front-to-back direction;

a plurality of contacts disposed in the housing and by two sides of the receiving cavity in a vertical direction perpendicular to said front-to-back direction, and categorized with signal contacts, power contacts and grounding contacts;

a metallic latch retained in the housing with a pair of locking heads extending into two opposite lateral sides of the receiving cavity for latchable engagement with a shielding plate which is embedded within a mating tongue of the receptacle connector during mating.

10. The plug connector as claimed in claim 9 wherein tail sections of the contacts are directly mounted to an internal printed circuit board.

11. The plug connector as claimed in claim 9 wherein the latch includes a pair of discrete latching arms with the corresponding locking heads, respectively.

12. The plug connector as claimed in claim 9 further including an EMI (Electro-Magnetic Interference) spring plate is sandwiched between the shell and the housing, wherein the spring plate is engaged with the housing in a horizontal plane.

13. The plug connector as claimed in claim 12, wherein said EMI spring plate includes a pair of spring tangs extending in a transverse direction perpendicular to both said front-to-back direction and said vertical direction.

14. The plug connector as claimed in claim 9, herein said shell is seamless and made from a drawing process, said shell defines a front small tubular section and a rear large tubular section, and a pair of cutouts are formed in a rear edge region of the large tubular section.

15. The plug connector as claimed in claim 14, wherein said front small tubular is essentially capsular while the rear large tubular section is essentially rectangular.

16. The plug connector as claimed in claim 14, where each of said cutouts extends through the rear large section and reaches the front small tubular section.

17. The plug connector as claimed in claim 14 wherein a plurality of locking protrusions are formed at a rear edge of the rear large tubular section.

18. The plug connector as claimed in claim 17, wherein said locking protrusions are split from the rear large tubular section and extend rearwardly beyond a rear edge of the rear large tubular section.

19. The plug connector as claimed in claim 9, wherein the latch is formed with an H like configuration having a transverse bar extending along the transverse direction with a pair of outwardly deflectable arms respectively extending forwardly from two opposite ends of the transverse bar at a same plane with the corresponding locking heads and with a pair of extensions respectively extending from said two opposite ends at different levels opposite to said same plane in the vertical direction.

20. The plug connector as claimed in claim 9, further including EMI (Electro-Magnetic Interference) spring plate sandwiched between the shell and the housing, wherein the insulative housing defines through holes distinct from each other, contacting ends extending from the spring plate in the front-to-back direction protruding into the receiving cavity through the corresponding through holes.
