Abstract

An electrical connector assembly includes a receptacle connector and a flippable pug connector for connecting with a cable. The receptacle connector includes a terminal module assembly defining a mating tongue loading with two rows of contacts on opposing surface of the mating tongue and a metallic shell retained on the terminal module assembly and enclosing the mating tongue, thereby defining a mating cavity between the metallic shell and the mating tongue. The plug connector includes an insulating housing defining a center slot with side walls and two rows of contacts on the side walls and a metallic shell attached to an outer periphery of the insulating housing. The mating cavity of the receptacle connector is configured to be symmetrical to a horizontal center line without orientation limits so as to allow the plug connector to be mated in two opposite orientations, and the center slot receives the mating tongue.

Claims

1. An electrical connector assembly comprising:

a first electrical connector for mounting to a printed circuit board, including;

a terminal module assembly defined by an upper terminal module and a lower terminal module commonly sandwiching a mating tongue in a vertical direction;

the upper terminal module including an upper insulator equipped with a plurality of upper contacts with corresponding contacting sections exposed upon one surface of the mating tongue; and

the lower terminal module including a lower insulator equipped with a plurality of lower contacts with corresponding contacting sections exposed upon the other surface of the mating tongue; and

a metallic shielding plate embedded within the mating tongue;

wherein said shielding plate defines protruding edges encompassing at least partially a boundary of the mating tongue for protection under an improper angular mating of a second connector;

wherein

said shielding plate defines a spring tang mechanically and electrically connected to a metallic shell enclosing the terminal module assembly.

2. The electrical connector assembly as claimed in claim 1, wherein the shielding plate includes at least one retaining rib extending downwardly into the lower terminal module.

3. The electrical connector assembly as claimed in claim 1, wherein the lower insulator forms a protrusion received within an opening of the shielding plate to align the lower terminal module and the mating tongue with each other in the vertical direction.

4. The electrical connector assembly as claimed in claim 1, wherein the lower insulator includes a mounting post for mounting to the printed circuit board.

5. The electrical connector assembly as claimed in claim 1, wherein the terminal module assembly is received in a metallic shell which defines a mating port with only one mating orientation.

6. The electrical connector assembly as claimed in claim 1, wherein tails of the lower contacts are of a through type while tails of the upper contacts are of a surface mount type.

7. The electrical connector assembly as claimed in claim 1, wherein said metallic shell includes a rear wall abutting against a rear side of the terminal module assembly and locked to opposite side regions of the shell.

8. The electrical connector assembly as claimed in claim 7, wherein the rear wall further includes mounting legs for mounting to said printed circuit board.

9. The electrical connector assembly as claimed in claim 8, wherein the shielding plate defines a pair of locking notches exposed outside of opposite lateral sides of the mating tongue for locking to a plug connector.

10. The electrical connector assembly as claimed in claim 9, wherein said second connector includes an insulative housing with therein a receiving cavity to receive said mating tongue therein, and a pair of laterally deflectable latch arms extending into the receiving cavity to lock with the locking notches, respectively.

11. The electrical connector assembly as claimed in claim 9, wherein said mating tongue forms a pair of notches in opposite lateral sides of the mating tongue in compliance with the locking notches, respectively, in the vertical direction.

12. An electrical connector for mounted on a printed circuit board, comprising:

a terminal module assembly defined by an upper terminal module and a lower terminal module commonly intimately sandwiching a shielding plate therebetween in a vertical direction;

wherein

the shielding plate defines a spring tang mechanically and electrically connected to a metallic shell enclosing the terminal module assembly.

13. The electrical connector assembly as claimed in claim 12, wherein said second connector includes an insulative housing with therein a receiving cavity to receive said mating tongue therein, and a pair of laterally deflectable latch arms extending into the receiving cavity to lock with the locking notches, respectively.

14. The electrical connector assembly as claimed in claim 12, wherein the shielding plate includes at least one retaining rib extending downwardly into the lower terminal module.

15. The electrical connector assembly as claimed in claim 12, wherein said metallic shell includes a rear wall abutting against a rear side of the terminal module assembly and locked to opposite side regions of the shell.

16. The electrical connector assembly as claimed in claim 15, wherein the rear wall further includes mounting legs for mounting to said printed circuit board.

17. An electrical connector assembly comprising:

a first connector for mounting to a printed circuit board, including;

a terminal module assembly defined by an upper terminal module and a lower terminal module commonly sandwiching a mating tongue in a vertical direction;

the upper terminal module including an upper insulator equipped with a plurality of upper contacts with corresponding contacting sections exposed upon one surface of the mating tongue; and
