Abstract

A receptacle includes an insulating housing including a base and a mating tongue, upper contacts and lower contacts, a metallic shell and a shielding plate. The contacts include plate contacting sections exposed upon the mating tongue. The shielding plate is disposed in the mating tongue and the base and isolated from the upper and lower contacts. The metallic shell is retained on the base and surrounding the mating tongue to define a mating port which is inserted with a plug connector in either of two insertion orientations. The front sides of the shielding plate is exposed to the front side of the mating tongue and the lateral sides of the shielding plates is exposed to the corresponding lateral sides of the mating tongue for protection under an improper angular mating of the plug connector.

Claims

1. A receptacle connector comprising:

an insulating housing comprising a base and a mating tongue extending from the base;

a plurality of upper contacts and a plurality of lower contacts, the contacts comprising plate contacting sections exposed upon opposite upper and lower surfaces of the mating tongue and leg portion extending from the base;

a shielding plate disposed in the mating tongue and the base and isolated from the upper and lower contacts; and

wherein the mating tongue defines two opposite lateral sides and a front side connecting with front ends of the two lateral sides thereof, the shielding plate defines corresponding lateral sides and corresponding front side thereof, the lateral sides of the shielding plate exposed to the corresponding lateral sides of the mating tongue for protection under an improper angular mating of the plug connector;

wherein the lateral sides of shielding plate slightly protrude beyond the mating tongue in a transverse direction perpendicular an inserting direction of the plug;

wherein the lateral sides of the shielding plate each defining an inflexible locking notch for assure direct locking with a pair of metallic latch of the plug connector when the receptacle connector is inserted with the plug connector, and each of the lateral sides of the mating tongue forms a through notch which is generally matching with the inflexible locking notch of each of the lateral sides of the shielding plate;

wherein the inflexible locking notches of the shielding plate protrude beyond the through notch of the mating tongue in the transverse direction.

2. The receptacle connector as claimed in claim 1, wherein the upper contacts and the lower contacts are embedded in the insulative housing by an inserting mold process.

3. The receptacle connector as claimed in claim 1, wherein the shielding plate is embedded in the insulative housing by an inserting mold process, the shielding plate further defines a thinned or even empty front region which is filler with insulative material of the mating tongue after the insert-molding process.

4. The receptacle connector as claimed in claim 1, comprising a metallic shell, wherein metallic shell is retained on the base and surrounding the mating tongue to define a mating port which is inserted with the plug connector in either of two insertion orientations, among the metallic shell and the mating tongue.

5. The receptacle connector as claimed in claim 1, wherein the front side of the shielding plate protrudes beyond the front side of the mating tongue.

6. The receptacle connector as claimed in claim 1, wherein the shielding plate defines cutouts running through the front side thereof, which are used for aligned with corresponding power contacts of the plug connector.

7. The receptacle connector as claimed in claim 1, wherein the shielding plate defines a thinner region extending along a mating direction of the receptacle connector and aligned with high frequent differential pair contacts of the upper and lower contacts to improve SS impedance control.

8. The receptacle connector as claimed in claim 1, wherein the upper contacts are inserted molded in an upper insulator with corresponding contacting sections embedded in the upper insulator, the lower contacts are inserted molded in an lower insulator with corresponding contacting sections embedded in the lower insulator, the shielding plate is wholly sandwiched between the upper insulator and the lower insulator.

9. The receptacle connector as claimed in claim 1, wherein the shielding plate is electrically and mechanically connected with the shielding shell.

10. The receptacle connector as claimed in claim 9, wherein the shielding plate defines a spring tab extending from rear end of the lateral side thereof and elastically touch with an inner of the metallic shell.

11. A flappable receptacle connector adapted for mating with a plug connector either in an upside direction or in an upside-down direction which defines a mating slot and a pair of metallic latches with hooks protruding into the mating slot, the receptacle connector comprising:

an insulating housing comprising a base and a mating tongue extending from the base, the mating tongue intending to insert in the mating slot of the plug connector;

a row of first contacts and a row of second contacts, the contacts comprising plate contacting sections exposed upon opposite surfaces of the mating tongue and leg section extending from the base;

a shielding plate disposed in the mating tongue and the base and isolated from the first and second contacts; and

wherein the mating tongue defines two opposite lateral sides and a front side connecting with front ends of the two lateral sides thereof, the shielding plate defines corresponding lateral sides and corresponding front side thereof, the lateral sides of the shielding plates slightly protruding beyond the corresponding lateral sides of the mating tongue in a transverse direction for protection under an improper angular mating of the plug connector;

wherein each lateral side of the shielding plate define an inflexible locking notch for locking with the hooks of the plug connector;

wherein the lateral sides of shielding plate slightly protrude beyond the mating tongue, and each of the lateral sides of the mating tongue forms a through notch which is generally matching with the inflexible locking notch of each of the lateral sides of the shielding plate;

wherein the inflexible locking notch slightly protrude beyond the corresponding through notches in the transverse direction.

12. The flappable receptacle connector as claimed in claim 11, wherein the shielding plate defines two longitudinal thinner regions extending in a mating direction of the receptacle connector and each aligned with a pair of high frequent different signal contacts.

13. The flappable receptacle connector as claimed in claim 11, wherein the shielding plate defines a longitudinal thinner region extending in a direction perpendicular to a mating direction of the receptacle connector at a front edge thereof.

14. The flappable receptacle connector as claimed in claim 11, wherein the shielding plate is mechanically connecting with a metallic shell surrounding the base of the insulating housing.

15. The flappable receptacle connector as claimed in claim 11, wherein grounding contacts of the contacts have middle curving portions touching the shielding plate.
