Abstract

A receptacle connector mounted to the printed circuit board, includes an insulative housing defining a mating tongue and a metallic shell enclosing the housing to form a mating cavity in which said mating tongue forwardly extends. A complementary plug connector includes a shell with a bull-nose tip. A metallic piece is mounted around a root of the mating tongue and equipped with a plurality of spring tangs to contact the relatively rigid bull-nose tip of the shell of the complementary connector for EMI/RFI protection.

Claims

1. A receptacle connector intended for mounting on a printed circuit board, comprising:

a top insert molding part including a top insulating housing equipped with a plurality of upper contacts with contacting sections extending beyond a front face of the top insulating housing;

a main insert molding part including a main insulating housing equipped with a metallic plate, the main insulating housing defining a plurality of grooves on a top surface and the metallic plate disposed between the top surface and a lower surface opposite to the top surface, the shielding plate being equipped with a pair of immoveable locking notches in two opposite lateral sides;

a metallic shell;

wherein the top insert molding part is assembled and retained on the main insert part and the contacting sections of the top insert molding art are received in the grooves of the main insert molding part so that a mating tongue is constructed;

wherein the main insert molding part includes a rear base and a front tongue, the grooves are disposed on the top surface of the front tongue, the opposite lateral sides of the shielding plates protrude beyond corresponding lateral sides of the front tongue;

wherein said metallic shell enclosing the insulating housing;

wherein the metallic shell comprises a front region surrounding the mating tongue to defines a mating cavity among the mating tongue the front region into which a plug connector is inserted in either of two insertion orientations, a middle retention region encircled the base and confronting against a pair of rear protrusions and a rear region with a rear stopper to limit a rearward movement of the insulating housing.

2. The receptacle connector as claimed in claim 1, wherein the rear stopper bends inward and presses against a rear face of base.

3. The receptacle connector as claimed in claim 1, wherein the front region defines a pair of front mounting legs and the rear region defines a pair of rear mounting legs.

4. The receptacle connector as claimed in claim 3, wherein each of the mounting legs defines a standoff region intended to stand on the printed circuit board.

5. The receptacle connector as defined claim 1, comprising:

a plug connector for coupling with the receptacle connector;

the plug connector comprises;

an insulative housing defining a receiving cavity;

a plurality of plug contacts disposed in opposite sides of receiving cavity of the insulative housing,

a metallic latch retained in the insulative housing and including a pair of resilient latching arms located in opposite lateral ends of the receiving cavity and protruding into the receiving cavity in a first direction; and

a one-piece metallic EMI bracelet enclosing a front end region of an exterior surface of the insulative housing with a plurality of spring fingers protruding into the receiving cavity in a second direction perpendicular to the first direction.

6. The plug connector as claimed in claim 5, wherein the front end region of insulative housing defines a plurality of slots, the spring fingers extend through the corresponding slots into the receiving cavity.

7. The receptacle connector as claimed in claim 1, wherein the main insert molding part includes a rear base and a front tongue, the grooves are disposed on the top surface of the front tongue, the opposite lateral sides of the shielding plates protrude beyond corresponding lateral sides of the front tongue.

8. The receptacle connector as claimed in claim 7, wherein the top insert molding part includes a base without any front tongue, the bases of the top insert molding part and the main insert molding part are retained together and are defined as a rear base on which the metallic shell is retained.

9. The receptacle connector as claimed in claim 8, wherein the metallic shell include a middle region fitly encircled the base and confronting against a pair protrusions rearward and a rear region including a rear stopper to limit a rearward movement of the base.

10. The receptacle connector as claimed in claim 8, wherein the metallic shell comprises a front region which defines the mating cavity, a middle region retained on the base in a vertical direction and a transverse direction and a rear region retained on the base in a front to back direction.

11. The receptacle connector as claimed in claim 10, wherein the front region defines a pair of front mounting legs and the rear region defines a pair of rear mounting legs.

12. The receptacle connector as claimed in claim 11, wherein each of the mounting legs defines a standoff region intended to stand on the printed circuit board.
