Abstract

An electrical connector includes an insulating housing, contacts, a shielding plate disposed in the housing and a metallic shell. The housing includes a base and a mating tongue, the base includes a retaining portion and a supporting portion extending downwards beyond the retaining portion. The contacts have contacting portions exposing to the mating surface and legs extending downwards from the supporting portion. The shielding plate defines a pair of side latches thereof. The metallic shell is retained on the retaining portion of the base and surrounds the mating tongue to define a mating cavity between the shell and the mating tongue. The connector further includes a front shielding member covering a front face of the supporting portion and a rear shielding member covering on a rear face of the supporting portion for shielding the legs of the contacts in a front and rear direction.

First claim

What is claimed is:

1 . An electrical connector comprising:
an insulating housing comprising a base and a mating tongue extending from the base, the mating tongue defining two opposite mating surfaces, the base comprises a retaining portion and a supporting portion extending downwards beyond the retaining portion, the supporting portion defining a front face and a rear face; a plurality of contacts with contacting portions exposing to the mating surface and legs extending downwards from the supporting portion; a shielding plate disposed in the insulating housing and between the two mating surfaces, the shielding plate defines a pair of side latches thereof; a metallic shell retained on the retaining portion of the base and surrounding the mating tongue to define a mating cavity between the metallic shell and the mating tongue; wherein the electrical connector further comprises a front shielding member located in front of the front face of the supporting portion and a rear shielding member located behind on the rear face of the supporting portion for shielding the legs of the contacts in a front-to-back direction.

2 . The electrical connector as claimed in claim 1 , wherein the metallic shell comprises a top wall, a bottom wall and two sidewalls, and the front shielding member integrally extends from a rear edge of the bottom wall.

3 . The electrical connector as claimed in claim 2 , wherein the electrical connector further comprises a metallic bracket surrounding said metallic shell, and the rear shielding member extends from the metallic bracket.

4 . The electrical connector as claimed in claim 3 , wherein the metallic bracket comprises a top wall and two sidewalls, the rear shielding wall perpendicularly bends from a rear edge of the top wall.

5 . The electrical connector as claimed in claim 4 , wherein lateral side faces of the supporting portion are covered by the two sidewalls of the bracket, respectively.

6 . The electrical connector as claimed in claim 1 , wherein the contacts are divided to two rows and each row at least comprises a power contact and a grounding contact, front distal ends of two power contacts of the two rows touch with each other and laser welded together.

7 . The electrical connector as claimed in claim 6 , wherein the front distal end of one power contact extends forwards beyond the other power contacts.

8 . The electrical connector as claimed in claim 6 , wherein front distal ends of the two grounding contacts touch with the shielding plate and laser welded to the shielding plate.

9 . The electrical connector as claimed in claim 2 , wherein the top wall of the metallic shell define two spring finger slantwise extending into the mating cavity.

10 . The electrical connector as claimed in claim 9 , wherein the top wall defines two protruding dimples at a front point and a rear point respectively of the spring finger.

11 . The electrical connector as claimed in claim 2 , wherein the bottom wall of the metallic shell define two protruding ribs into the mating cavity, the two protruding ribs are parallel to each other and each extends in the front and rear direction.

12 . The electrical connector as claimed in claim 1 , wherein said front shielding member intimately covers the front face of the supporting portion, and said rear shielding member intimately covers the rear face of the supporting portion.

13 . An electrical connector comprising:
an insulating housing comprising a base and a mating tongue extending from the base, the mating tongue defining a first mating surface and a second mating surface opposite to the first mating surface; a row of first contacts at least comprising a power contact and a grounding contact, each first contact including a contacting portion exposing to the first mating tongue and a leg extending from the base; a row of second contacts at least comprising a power contact and a grounding contact, each second contact including a contacting portion exposing to the second mating tongue and a leg extending from the base; a shielding plate embedded in the insulating housing and disposed between the first contacts and the second contacts; wherein front distal ends of the power contacts of the first and second contacts are touched with each other and laser-welded together.

14 . The electrical connector as claimed in claim 13 , wherein the front distal end of power contact of the second contacts extends forwards beyond the front distal end of the power contact of the first contacts.

15 . The electrical connector as claimed in claim 13 , wherein front distal ends of the grounding contacts of the first and second contacts touch with the shielding plate and are laser welded to the shielding plate.

16 . The electrical connector as claimed in claim 13 , wherein the shielding plate defines a notch at a front edge thereof with a rear edge facing forwards and two side edges, the rear edge is divided to two side portions and a middle portion between the two side portions, the two side portions are defined to be behind the middle portion and the front distal ends of the power contacts extend in front of the side portion.

17 . An electrical connector comprising:
an insulating housing comprising a base and a mating tongue extending from the base, the mating tongue defining a first mating surface and a second mating surface opposite to the first mating surface in a vertical direction; a row of first contacts at least comprising a power contact and a grounding contact, each first contact including a contacting portion exposing to the first mating tongue and a leg extending from the base; a row of second contacts at least comprising a power contact and a grounding contact, each second contact including a contacting portion exposing to the second mating tongue and a leg extending from the base; a shielding plate embedded in the insulating housing and disposed between the first contacts and the second contacts; wherein a distal end of the grounding contact of the first contacts cooperate with a distal end of the grounding contact of the second contacts to sandwich the metallic shielding plate therebetween in said vertical direction under a welded manner not only for electrical connection but also for mechanical reinforcement therebetween.

18 . The electrical connector as claimed in claim 17 , wherein said distal ends are located on a front side of the housing.

19 . The electrical connector as claimed in claim 17 , wherein said distal ends are located on a lateral side of the housing.

20 . The electrical connector as claimed in claim 17 , wherein front distal ends of the power contacts of the first and second contacts are directly contacted with each other and welded together.
