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 first insert molding part including a first insulating housing inserting molded with a row of first contacts with contacting sections extending beyond a front face of the first insulating housing; and

a second insert molding part including a second insulating housing inserting molded with a metallic plate;

wherein the second insert molding part includes a rear base and a front tongue, a plurality of grooves are disposed on a first surface of the front tongue, the opposite lateral sides of the shielding plates protrude beyond corresponding lateral sides of the front tongue and provides a pair of immoveable locking edges;

wherein the first insert molding part is assembled and retained on the second insert part in an upper to lower direction so that the contacting sections of the first insert molding part are received in the grooves of the second insert molding part thereby forming a mating tongue;

further comprising a metallic shell surrounding the mating tongue to define a mating cavity between the metallic shell and the mating tongue into which a plug connector is inserted in either of two insertion orientations;

wherein

the first insert molding part includes a base without any front tongue, the bases of the first insert molding part and the second insert molding part are retained together and are defined as a main base on which the metallic shell is retained;

wherein

the metallic shell comprises a front region surrounding the mating tongue to define the mating cavity, a middle region fitly encircled the main base and confronting against a pair of rear protrusion and a rear region with a rear stop to limit a rearward movement of the main base.

2. 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.

3. The receptacle connector as claimed in claim 2, wherein each of the mounting legs defines a standoff region intended to stand on the printed circuit board.

4. A receptacle connector comprising:

a first insert molding part including a first insulating housing inserting molded with a row of first contacts with contacting sections extending beyond a front face of the first insulating housing and tails extending out of the first insulating housing; and

a second insert molding part including a second insulating housing inserting molded with a metallic plate and a row of second contacts;

wherein the second insert molding part includes a rear base and a front tongue, a plurality of grooves are disposed on a first surface of the front tongue, the second contacts includes contacting section embedded and exposing to a second surface of the front tongue and tails extending out of the rear base, the shielding plate extends from the front tongue to the rear base with a pair of a pair of immoveable locking edges protruding beyond lateral sides of the front tongue;

wherein the first insert molding part is attached on the second insert molding part in a vertical direction and the contacting sections of the first insert molding part are received in the grooves of the second insert molding part thereby forming a mating tongue.

5. The receptacle connector as claimed in claim 4, comprising a metallic shell, wherein the metallic shell fitly retained on the first insulating housing and the rear base and surrounding the mating tongue to define a mating cavity among the metallic shell and the mating tongue.

6. The receptacle connector as claimed in claim 4, wherein the first insulating housing defines a retained post and the rear base of the second insulating housing defines a retained hole engaged with the retained post.

7. A manufacturing method of a receptacle connector, the improvement comprising:

providing a first insert molding part including a first insulating housing equipment with a row of first contacts with contacting sections extending beyond a front face of the first insulating housing;

providing a second insert molding part including a second insulating housing equipment with the metallic plate, wherein the second insert molding part includes a rear base and a front tongue, a plurality of grooves are disposed on a first surface of the front tongue;

assembling the first insert molding part on the second insert part, wherein the contacting sections of the first insert molding part received in the grooves of the second insert molding part thereby forming a matting tongue which is used to inserted into a mating slot of a plug connector;

wherein

a metallic shell is retained on the first insulating housing and the rear base and surrounding the mating tongue to define a mating cavity among the metallic shell and the mating tongue;

wherein

the metallic shell comprises a rear wall with a pair of locking ears bending forward, the locking ears are locked with the metallic shell.
