Abstract

A plug connector includes an insulative housing with mating slot, contacts disposed in the housing by two sides of the mating slot, and a pair of side arms located by two opposite ends of the mating slot in a horizontal transverse direction. a receptacle connector includes an insulative housing defining a horizontal mating tongue; contacts disposed in the housing with contacting sections exposed upon two opposite surfaces of the mating tongue; and a monolithic horizontal metallic shielding plate disposed and extending substantially fully the mating tongue. The shielding plate defines side protruding edge sections exposed outside of corresponding side edges of the mating tongue and a notch structure on each side protruding edge section, the pair of side arms each defines a hook structure to engagement with the notch structure.

First claim

What is claimed is:

1. An electrical connector assembly comprising:
a plug connector connected to a cable, including:
an insulative plug housing with mating slot therein,
a plurality of plug contacts disposed in the insulative plug housing by two sides of the mating slot in a vertical direction, and
a pair of metallic side arms located by two opposite ends of the mating slot in a transverse direction perpendicular to said vertical direction; and
a receptacle connector adapted to be mated with the plug connector, the receptacle connector including:
an insulative receptacle housing defining a mating tongue;
a plurality of receptacle contacts disposed in said receptacle housing with contacting sections exposed upon two opposite surfaces of the mating tongue; and
a monolithic metallic shielding plate disposed and extending substantially fully within the mating tongue; wherein
the shielding plate of the receptacle connector defines side latching edge sections exposed upon corresponding side edges of the mating tongue and a notch structure on each of the side latching edge sections, each of the pair of side arms of the plug connector defines a hook structure for engagement with the notch structure of the receptacle connector during mating.

2. The electrical connector assembly as claimed in claim 1 , wherein the pair of side arms are unitarily linked by a transverse bar to commonly form a U-shaped latch.

3. The electrical connector assembly as claimed in claim 1 , wherein a side edge of the shielding plate protrudes beyond the side edge of the mating tongue, and a front edge of the shielding plate protrudes beyond a front edge of the mating tongue.

4. The electrical connector assembly as claimed in claim 1 , wherein the plug connector comprises a paddle card located behind the insulative plug housing, said cable extending rearwards from a rear portion of the paddle card, a front metallic shell enclosing the insulative plug housing and a rear metallic shell enclosing the paddle card and a front portion of the cable.

5. The electrical connector assembly as claimed in claim 4 , wherein said front metallic shell is essentially a seamless sleeve.

6. The electrical connector assembly as claimed in claim 4 , wherein the front metallic shell and the rear metallic shell are linked to each other around boundary.

7. The electrical connector assembly as claimed in claim 1 , wherein said plug connector further includes a front metallic shell enclosing the plug housing, and said front metallic shell is essentially of a seamless sleeve.

8. The electrical connector assembly as claimed in claim 1 , wherein the side edge of the mating tongue defines another notch structure into which the notch structure of the side latching edge section of the shielding plate protrudes and exposed in the vertical direction.

9. An electrical connector assembly comprising:
a receptacle connector adapted to be mounted to a printed circuit board for mating with a plug connector, and including:
an insulative housing defining a mating tongue;
a plurality of contacts disposed in the housing with contacting sections exposed upon two opposite surfaces of the mating tongue;
a monolithic horizontal metallic shielding plate disposed and extending substantially fully within the mating tongue; and
a metallic shield enclosing said housing to define a mating cavity with the mating tongue extending therein, said shield including opposite top and bottom walls and two opposite side walls, and further including a rear wall having two ears latched to the corresponding opposite side walls, respectively; wherein
the shielding plate of the receptacle connector defines side latching edge sections exposed upon corresponding side edges of the mating tongue and a notch structure formed on each of said side latching edge sections for latching to a corresponding metallic side arm of the plug connector during mating.

10. The electrical connector assembly as claimed in claim 9 , wherein said rear wall further includes at least one leg around a bottom edge for mounting to the printed circuit board for reinforcement.

11. The electrical connector assembly as claimed in claim 9 , wherein said shielding plate is assembled within the mating tongue as one piece via an insert molding process, and the contacts are formed within a terminal module via another insert molding process and successively assembled to the mating tongue in a vertical direction.

12. An electrical connector assembly comprising:
a plug connector connected to a cable, including:
an insulative plug housing defining a mating slot;
a plurality of plug contacts disposed in the insulative housing by two opposite sides of the mating slot in a vertical direction; and
a pair of side arms located by two opposite ends of the mating slot and between the contacts in a transverse direction perpendicular to said vertical direction;
wherein
each of the pair of side arms defines a front hook structure extending forwards and face inwardly toward the mating slot in the transverse direction, and is formed via stamping from a sheet metal; wherein
the insulative plug housing is enclosed within a front metal shell, and the side arms define side edges to mechanically and electrically contact an interior surface of the front metallic shell for constant self-grounding in the plug connector.

13. The electrical connector assembly as claimed in claim 12 , wherein the pair of side arms is linked by a transverse bar to form a U-shaped latch.

14. The electrical connector assembly as claimed in claim 13 , wherein said plug connector further includes a paddle card positioned behind the U-shaped latch in a coplanar manner.

15. The electrical connector assembly as claimed in claim 12 , further including a receptacle connector, wherein said receptacle connector includes:
an insulative receptacle housing defining a mating tongue;
a plurality of receptacle contacts disposed in the housing with contacting sections exposed upon two opposite surfaces of the mating tongue; and
a monolithic horizontal metallic shielding plate disposed and extending substantially fully within the mating tongue; wherein
the shielding plate of the receptacle connector defines side latching edge sections exposed upon corresponding side edges of the mating tongue and a notch structure formed on each of said side latching edge sections for latching to the corresponding one of said metallic side arms of the plug connector during mating.

16. The electrical connector assembly as claimed in claim 12 , wherein the front metal shell is of essentially a seamless sleeve.
