Abstract

An electrical connector includes an insulative housing, a plurality of contacts disposed in the housing, and a metallic shield enclosing the housing. The contacts includes a row of first contacts and another row of second contacts. The insulative housing includes a main base and a tongue portion extending forwardly from the body. The metallic shield includes a main body, a tubular section extending forwardly from the main body, an inner part forwardly extending from the main body and inside said tubular section. The inner part forms a receiving space in which the tongue portion is received.

First claim

What is claimed is:

1 . An electrical connector comprising:
a unitary metallic shield including a main body, a tubular section forwardly extending from the main body in a front-to-back direction, and an inner part located in the tubular section and extending forwardly in said front-to-back direction and defining a receiving cavity therein; an insulative housing enclosing within the metallic shield and including a main base and a tongue portion forwardly extending from the main base in said front-to-back direction; and a plurality of contacts disposed in the housing; wherein the tongue portion is protectively and snugly received within the receiving cavity for mating.

2 . The electrical connector as claimed in claim 1 , wherein said inner part including a frame structure, a pair of side arms spaced from each other in a transverse direction perpendicular to said front-to-back direction and forwardly extending from two opposite lateral sides of the frame structure in said front-to-back direction; and said tongue portion forwardly extends through the frame structure in said front-to-back direction, and two lateral sides of the tongue portion are protectively engaged with the corresponding side arms so as to form a reinforced tongue portion for mating.

3 . The electrical connector as claimed in claim 2 , wherein said inner part further includes a pair of front arms respectively extending from free ends of the corresponding side arms toward each other in the transverse direction, and a front edge region of the tongue portion forwardly abuts against the corresponding front arms in the front-to-back direction.

4 . The electrical connector as claimed in claim 3 , further including means for retaining the front edge region of the tongue portion to the corresponding front arms in a vertical direction perpendicular to both said front-to-back direction and said transverse direction.

5 . The electrical connector as claimed in claim 3 , wherein said tongue portion further includes a protrusion on the front edge region between the pair of front arms in the transverse direction.

6 . The electrical connector as claimed in claim 2 , further including means for retaining the lateral sides of the tongue portion to the corresponding side arms, respectively, in a vertical direction perpendicular to both said front-to-back direction and said transverse direction.

7 . The electrical connector as claimed in claim 2 , wherein said frame structure forms a complete loop circumferentially, and extends along the front-to-back direction with a distance to include opposite top and bottom plates for grounding during mating with a complementary connector.

8 . The electrical connector as claimed in claim 1 , wherein the metallic shield is made via die-casting and has different thicknesses at different positions, and includes a plurality of stopping arms having a less thickness compared with remaining portions thereof.

9 . The electrical connector as claimed in claim 1 , wherein said insulative housing further defines a slot around a root region of the tongue portion, in which a side plate of the frame structure is received.

10 . The electrical connector as claimed in claim 1 , wherein said pair of side arms are configured and positioned to function as grounding contacts for mating with corresponding grounding terminals of a complementary plug connector.

11 . A method of making an electrical connector, comprising steps of:
providing a unitary metallic shield via a die-casting process with a main body, a tubular section extending forwardly from the main body along a front-to-back direction, and an inner part located in the tubular section and extending forwardly in the front-to-back direction and having a pair of side arms to form a receiving cavity; providing an insulative housing with a plurality of contacts therein wherein said housing includes a main base and a tongue portion extending forwardly from the main base; providing a plurality of contacts disposed within the insulative housing; and forwardly inserting the tongue portion of the insulative housing into the receiving cavity; wherein two opposite lateral side edges of the tongue portion are protectively and intimately engaged with the side arms, respectively.

12 . The method as claimed in claim 11 , wherein said inner part further has a frame structure from which a pair of side arms extend forwardly from two opposite lateral sides of the frame structure, respectively.

13 . The method as claimed in claim 12 , further including a step of providing said pair of side arms with a pair of front arms linked to corresponding free ends, respectively, wherein a front edge region of the tongue portion abuts against the pair of front arms in the front-to-back direction.

14 . The method as claimed in claim 11 , further providing means for engaging the lateral side edges of the tongue portion with the corresponding side arms, respectively, or means for engaging the front arms with the front edge region of the tongue portion.

15 . The method as claimed in claim 13 , further including a step of providing a protrusion on a front edge region of the tongue portion to be located between the pair of front arms in a transverse direction perpendicular to said front-to-back direction.

16 . An electrical connector comprising:
a unitary metallic shield including a main body, a tubular section forwardly extending from the main body in a front-to-back direction, and an inner part located around a border of the main body and the tubular section and including a frame structure having at least opposite top and bottom plates, an insulative housing enclosing within the metallic shield and including a main base and a tongue portion forwardly extending from the main base in said front-to-back direction; and a plurality of contacts disposed in the housing; wherein the tongue portion forwardly extends through the frame structure in said front-to-back direction, and said top and bottom plates form step structures with regard to the tongue portion to function as a grounding device which is adapted for mating with a grounding part of a complementary connector.

17 . The electrical connector as claimed in claim 16 , wherein said inner part is connected to the border via a vertical connecting wall.

18 . The electrical connector as claimed in claim 16 , further including a pair of side arms unitarily extending from two opposite lateral sides of the frame structure to protective engagement with corresponding side edge regions of the tongue portion for reinforcement of the tongue portion.

19 . The electrical connector as claimed in claim 18 , further including a pair of front arms unitarily extending from free ends of said pair of side arms toward each other for protective engagement with a front edge region of the tongue portion.

20 . The electrical connector as claimed in claim 19 , further including a protrusion formed on the front edge region of the tongue portion and located between said pair of front arms in a transverse direction perpendicular to said front-to-back direction.
