Abstract

An electrical connector includes a contact module and a mating/outer case enclosing the contact module. The mating case includes an insulative shell with a metallic reinforcement bracket embedded therein. The insulative shell forms opposite inner and outer surfaces wherein the inner surface forms a mating cavity for receiving a complementary plug connector therein, and the bracket is essentially located between the outer surface and the inner surface except the corresponding mounting legs extending out of the insulative shell for mounting to a printed circuit board.

Claims

1. An electrical connector comprising:

a mating case having an insulative shell and a metallic reinforcement bracket integrally formed with each other via an insert-molding process, said insulative shell defining opposite interior and exterior surfaces, said interior surface directly defining a mating cavity for directly and intimately receiving a complementary plug connector, said metallic reinforcement bracket embedded within the insulative shell and between said opposite interior and exterior surfaces except mounting legs extending out of the insulative shell for mounting to a printed circuit board; and

a contact module assembled in the mating case and including a mating tongue extending into the mating cavity;

wherein

the metallic reinforcement bracket is fixed to the contact module;

wherein

the contact module includes an insulative body integrally formed with a plurality of contacts and a pair of latching pieces, and said metallic reinforcement bracket is fixed at least either to the insulative body by having a securing tab retained in a cutout of the insulative body, or to the latching pieces.

2. The electrical connector as claimed in claim 1, wherein the metallic reinforcement bracket defines a mounting leg soldered with a securing leg of the corresponding latching piece.

3. The electrical connector as claimed in claim 1, wherein said insulative body includes a first base abutting against the insulative shell, and a second base rearwardly spaced from the first base.

4. The electrical connector as claimed in claim 3, wherein said first base is enclosed within the insulative shell while said second base is exposed outside of a rear edge of the insulative shell.

5. The electrical connector as claimed in claim 1, wherein said contact module includes an insulative body integrally formed with a plurality of contacts and a pair of latching pieces, and the mating case forms a stopping face against which the insulative body forwardly abuts.

6. The electrical connector as claimed in claim 1, wherein a waterproof plate is applied upon a rear side of the insulative shell and flush with a rear edge of the insulative shell.

7. The electrical connector as claimed in claim 1, wherein said metallic reinforcement bracket includes a plurality of embossments exposed toward the mating cavity.

8. A method of making an electrical connector, comprising steps of:

applying an insulative shell upon a metallic reinforcement bracket via an insert-molding process wherein said insulative shell defines opposite interior and exterior surfaces, the interior surface directly defining a mating cavity for directly and intimately receiving a complementary plug connector, the metallic reinforcement bracket being embedded within the insulative shell and between the interior surface and the exterior surface except mounting legs extending out of the insulative shell for mounting to a printed circuit board;

forwardly inserting a contact module into the insulative shell; and

securing the contact module to the metallic reinforcement bracket;

wherein

the step of securing the contact module to the metallic reinforcement bracket includes soldering a mounting leg of the metallic reinforcement bracket to a securing leg of a latching piece of the contact module, or bending a securing tab into a cutout of an insulative body of the contact module.

9. The method as claimed in claim 8, wherein the insulative shell forms a stopping face against which the contact module abuts forwardly.

10. The method as claimed in claim 9, wherein the contact module includes a first base abuts against the stopping face, and a second base rearwardly spaced from the first base.

11. The method as claimed in claim 10, wherein a waterproof plate located between the first base and the second base, is secured to the first base while space from the second base.

12. An electrical connector comprising:

a mating case having an insulative shell and a metallic reinforcement bracket integrally formed with each other via an insert-molding process, said insulative shell defining opposite interior surface and exterior surface, said interior surface directly defining and surrounding a mating cavity for intimately receiving a complementary plug connector, said metallic reinforcement bracket forming no portions extending along a front-to-back direction on the interior surface for surrounding the mating cavity; and

a contact module assembled in the mating case and including a mating tongue extending into the mating cavity along the front-to-back direction;

wherein

the contact module includes an insulative body integrally formed with a plurality of contacts and a pair of latching pieces on two opposite lateral sides, and the mating case forms a stopping face against which the insulative body forwardly abuts;

wherein

the metallic reinforcement bracket is fixed to the contact module;

wherein

said metallic reinforcement bracket is fixed at least either to the insulative body by having a securing tab retained in a cutout of the insulative body, or to the latching pieces.

13. The electrical connector as claimed in claim 12, wherein said stopping face is formed by the insulative shell.

14. The electrical connector as claimed in claim 12, wherein said metallic reinforcement bracket further includes mounting legs extending out of the insulative shell for mounting to a printed circuit board.
