Abstract

An electrical connector (100) includes an insulative housing (2), a number of contacts (3) retained in the insulative housing, a metal shield (4) covering the insulative housing for defining a receiving space, an insulative cover (5) insert-molded outside of the metal shield, and a metal frame (6) retained in the insulative cover. The metal frame includes a transverse arm (61) and a pair of vertical arms (62) extending downwardly from two distal ends of the transverse arm for reinforcing the metal shield from three sides of the metal shield.

Claims

1. An electrical connector comprising:

an insulative housing;

a plurality of contacts retained in the insulative housing;

a metal shield covering the insulative housing for defining a receiving space;

an insulative cover insert-molded outside of the metal shield; and

a metal frame retained in the insulative cover, the metal frame comprising a transverse arm and a pair of vertical arms extending downwardly from two distal ends of the transverse arm.

2. The electrical connector as claimed in claim 1, wherein the insulative cover comprises an upper face, a lower face opposite to the upper face, and a pair of lateral faces connecting with the upper face and the lower face, and the transverse arm is retained in the upper face and the vertical arms are retained in the lateral faces.

3. The electrical connector as claimed in claim 2, wherein the lower face is adapted for abutting against a printed circuit board.

4. The electrical connector as claimed in claim 2, wherein the vertical arms extend out of the lower face for board locking in a printed circuit board.

5. The electrical connector as claimed in claim 2, wherein the insulative cover comprises a front portion, a rear portion extending rearwardly from the front portion, and a stepped portion formed on the rear portion with a height lower than other parts of the rear portion, and wherein the metal frame comprises a plurality of pin members coplanar with the stepped portion to expose out of the insulative cover.

6. The electrical connector as claimed in claim 5, wherein the pin members extend oppositely, outwardly from two ends of the transverse arm.

7. The electrical connector as claimed in claim 5, wherein the pin members comprises at least one pair of pin members respectively located at two opposite sides of the vertical arm.

8. The electrical connector as claimed in claim 5, wherein the pin members are formed by cutting from a carrier.

9. The electrical connector as claimed in claim 5, wherein each vertical arm comprises a lower wider portion, an upper narrower portion connecting the lower wider portion with the transverse arm, and a shoulder portion formed between each side of the lower wider portion and the upper narrower portion.

10. The electrical connector as claimed in claim 9, wherein the pin members and the shoulder portions are wrapped by insulative material.

11. The electrical connector as claimed in claim 1, wherein the transverse arm defines a cutout and each vertical arm defines an aperture, and wherein the cutout and the apertures are filled with plastic materials to thereby combine the insulative cover and the metal frame.

12. An electrical connector comprising:

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

a plurality of contacts disposed in the housing with contacting sections exposed upon the mating tongue;

a metallic shell assembled to and the housing and enclosing the mating tongue, said shell forming at least a board lock on a rear side for mounting to a printed circuit board;

an insulative cover enclosing the shell; and

a metallic bracket mostly embedded within the cover;

wherein

said bracket is equipped with at least one arm extending downwardly beyond a bottom side of the cover for mounting to the printed circuit board.

13. The electrical connector as claimed in claim 12, wherein the board lock is located behind the arm in a front-to-back direction.

14. The electrical connector as claimed in claim 13, wherein the board lock is located on an outer side with regard to the arm in a transverse direction perpendicular to said front-to-back direction.

15. The electrical connector as claimed in claim 12, wherein the bracket is embedded within the cover via an insert molding process, and an interior side of the cover and an exterior contour of the shell are configured and dimensioned to be snugly coupled with each other so as to allow the shell to be forwardly assembled into the cover from a rear side of the cover, and a glue block is applied upon a rear side of the cover to seal a circumferential gap between the shell and the cover.

16. The electrical connector as claimed in claim 12, wherein the bracket further includes a pair of pin members located by two sides of the arm in a front-to-back direction.

17. The electrical connector as claimed in claim 12, wherein the bracket has a portion exposed upon a top face of the cover for use with a mold during an insert molding process

18. An electrical connector comprising:

an insulative housing equipped with a plurality of contacts via an insert molding process;

a metallic shell assembled to the housing;

an insulative cover enclosing the shell;

a waterproof ring attached upon a front edge of the cover;

a glue block attached to a rear side of the cover to seal a circumferential gap between the shell and the cover; and

a metallic bracket embedded within the bracket via another insert molding process and defining a U-shaped structure, in a front view, with a pair of arms exposed outside of the cover for mounting to a printed circuit board.

19. The electrical connector as claimed in claim 18, wherein the shell further includes a pair of board locks exposed outside of the cover and located behind the pair of arms in a front-to-back direction.

20. The electrical connector as claimed in claim 18, wherein the bracket has a portion exposed upon a top face of the cover for use with a mold during the insert molding process.
