Abstract

A plug connector for use with a complementary receptacle connector, includes an insulative housing defining a receiving cavity therein and a plurality of passageways on opposite of the mating cavity, a pair of terminal modules stacked on each other and a metallic shell. Each terminal module includes an insulator and a plurality of contacts loaded on insulator, the contacts includes contacting sections extending out of the insulator and tail extending out of the insulator. The insulators of the stacked terminal modules are located behind the insulative housing and the contacting sections of the contacts are disposed in the corresponding passageways. The terminal modules and the insulative housing are commonly enclosed in the metallic shell.

Claims

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

an insulative housing defining a receiving cavity therein and a plurality of passageways on opposite of the mating cavity;

a pair of terminal modules stacked on each other, each terminal module comprising an insulator and a plurality of contacts loaded on the insulator, the contacts comprising contacting sections extending out of a front side of the insulator and tails extending out of the insulator; and

a metallic shell;

wherein

the insulators of the stacked terminal modules are located behind the insulative housing, and the contacting sections of the contacts are disposed in the corresponding passageways, and the terminal modules and the insulative housing are commonly enclosed in the metallic shell;

wherein

a metallic latch is sandwiched between the pair of insulators and equipped with a pair of side arms, said pair of side arms having corresponding locking heads sidewardly extending into the receiving cavity for locking with a metallic shielding plate of a receptacle connector into which said plug connector is inserted.

2. The plug connector as claimed in claim 1, wherein each insulator of the terminal modules defines an assembled post and an assembly hole on an inner side to be coupled with those of the other insulator.

3. The plug connector as claimed in claim 1, wherein each insulator of the terminal module defines a pair of posts in the front side thereof to be inserted into a corresponding pair of holes in a rear side of the insulative housing to assemble the insulative housing and the insulator together.

4. The plug connector as claimed in claim 1, further comprising a pair of insulating tapes disposed upon two opposite sides of the insulative housing so as to isolate the contacting sections of the contact from the metallic shell.

5. The plug connector as claimed in claim 1, wherein the metallic latch is U-shaped with said pair of side arms thereof, and the insulative housing defines a pair of side slots to receive the two side arms of the metallic latch and the heads of the side arms extend into the receiving cavity.

6. The plug connector as claimed in claim 5, wherein each insulator of the terminal modules defines a U-shaped recess formed in the inner side thereof to receive the U-shaped metallic latch.

7. The plug connector as claimed in claim 5, comprising a paddle card connecting with the tails of the contacts.

8. The plug connector as claimed in claim 7, wherein the metallic latch defines a pair of mounting legs respectively rearwardly extending from the two opposite ends restrictively to reach and connecting with two grounding conductive pads of the paddle card.

9. The plug connector as claimed in claim 1, wherein the housing includes a rear face through which said plurality of passageways rearwardly extend, and the front side of the insulator abuts against the rear face of the housing.

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

an insulative housing defining a rear base and a front mating tongue forwardly extending, with a step portion defined at a root region of the mating tongue;

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 collar surrounding the step portion;

a metallic shielding plate embedded within the mating tongue;

wherein the metallic collar mechanically and electrically connects to the corresponding grounding contacts.

11. The receptacle connector as claimed in claim 10, wherein one of the metallic collar or the corresponding grounding contact forms a spring tab to contact the other.

12. The receptacle connector as claimed in claim 11, wherein said spring tab is formed upon the metallic collar.

13. The receptacle connector as claimed in claim 10, wherein the metallic collar defines a retaining plate rearwardly extending and retained in a slit of the insulative housing.

14. The receptacle connector as claimed in claim 10, wherein the shielding plate defines a pair of protrusions unitarily bulged downwardly therefrom to replace and function as corresponding grounding contacting section for corresponding grounding contacts to be exposed on the lower surface of the mating tongue.

15. The receptacle connector as claimed in claim 10, comprising a subsidiary plate, wherein the subsidiary plate forms a pair of bulged protrusions unitarily extending upwardly to be exposed upon the upper surface of the mating tongue for functioning as the contacting section of the corresponding grounding contact with mechanical and electrically connection to the corresponding grounding contact.

16. A receptacle connector for mating with a plug connector, comprising:

an insulative housing including a base and a mating tongue extending forwardly therefrom;

a metallic shell enclosing said housing to define a mating cavity in which said mating tongue extends;

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

a step structure formed upon a root region of the mating tongue;

a metallic collar disposed upon the step structure;

a metallic shield embedded with the mating tongue and forming a pair of notches in two opposite lateral side edges as a locking device;

wherein

a pair of switch contacts are located around a front face of the base and spaced from each other when no plug is inserted into the mating cavity while contacting with each other when the plug connector is inserted into the mating cavity.

17. The receptacle connector as claimed in claim 16, wherein the shielding plate includes at least one protruding ribs exposed upon the mating tongue for mating with the plug connector and to mechanically and electrically contact one corresponding shortened grounding contact.

18. The receptacle connector as claimed in claim 17, wherein a front end of said shortened grounding contact extends toward a front edge region of the collar.

19. The receptacle connector as claimed in claim 17, wherein said front end of said shortened grounding contact intimately confronts the front edge region of the collar.

20. The receptacle connector as claimed in claim 16, wherein said housing includes a pair of terminal modules commonly sandwiching the metallic shielding plate therebetween.
