Abstract

An electrical connector includes an insulating housing, a middle shielding plate integrally molded to the insulating housing, and a plurality of terminals received in the insulating housing. The insulating housing has a base portion and a tongue portion. A front section of the tongue portion has two fixing portions. The middle shielding plate has a base plate, an extending plate, and two bending portions formed at two opposite sides of a front end of the extending plate. The two bending portions are respectively molded in the two fixing portions. Outer side surfaces of the two bending portions are exposed outside from two opposite sides of the two fixing portions. A thickness of each of the bending portions is greater than a thickness of the extending plate.

First claim

What is claimed is:

1. An electrical connector, comprising:
an insulating housing having a base portion, and a tongue portion protruded frontward from a front surface of the base portion, a front section of the tongue portion having a main portion, and two fixing portions protruded outward from two opposite sides of the main portion;
a middle shielding plate integrally molded in the insulating housing, the middle shielding plate having a base plate, an extending plate extended frontward from a front edge of the base plate, and two bending portions formed at two opposite sides of a front end of the extending plate, the extending plate being molded in the tongue portion, two opposite side surfaces of the extending plate being exposed outside from two opposite sides of the main portion of the tongue portion, the two bending portions respectively molded in the two fixing portions, outer side surfaces of the two bending portions being exposed outside from two opposite sides of the two fixing portions, a thickness of each of the bending portions being greater than a thickness of the extending plate; and
a plurality of terminals received in the insulating housing.

2. The electrical connector as claimed in claim 1 , wherein each of the bending portions has a rising section slantwise extended frontward and upward from one of the two opposite sides of the front end of the extending plate, and a curving section connected with a front end of the rising section.

3. The electrical connector as claimed in claim 2 , wherein the curving section includes an upper piece connected with the rising section, a lower piece opposite to the upper piece, and a bending piece connected between front ends of the upper piece and the lower piece, the lower piece is spaced from the upper piece to form an interstice between the lower piece and the upper piece.

4. The electrical connector as claimed in claim 3 , wherein a distance between a top surface of the upper piece and a bottom surface of the lower piece is greater than a distance between a top surface and a bottom surface of the extending plate.

5. The electrical connector as claimed in claim 3 , wherein the lower piece and the upper piece of each of the bending portions are aligned with each other up and down.

6. The electrical connector as claimed in claim 1 , wherein the two bending portions are punched upward and then curved rearward from two opposite sides of the front end of the extending plate.

7. The electrical connector as claimed in claim 1 , wherein the two bending portions are shown lying narrow U shapes with mouths of the two bending portions facing rearward.

8. The electrical connector as claimed in claim 1 , wherein a periphery of the tongue portion is connected with a ring-shaped blocking rib, the blocking rib is spaced from the front surface of the base portion to form a receiving groove between the blocking rib and the base portion, the electrical connector further includes an inner shielding shell assembly, the inner shielding shell assembly is mounted in the receiving groove.

9. The electrical connector as claimed in claim 8 , wherein the inner shielding shell assembly includes an upper shell and a lower shell, the upper shell has a first main plate, two opposite sides of the first main plate are bent downward to form two first buckling arms, the two first buckling arms are punched outward to form two buckling pieces, the lower shell has a second main plate, two opposite sides of the second main plate are bent upward to form two second buckling arms, the two second buckling arms define two buckling holes, the first main plate is received in a top of the receiving groove, the second main plate is received in a bottom of the receiving groove, the first buckling arms and the second buckling arms are received in the two opposite sides of the receiving groove, the buckling pieces are buckled in the buckling holes.

10. The electrical connector as claimed in claim 9 , wherein the base portion defines two first recesses penetrating through two opposite sides of a top surface and the front surface of the base portion, the base portion defines two second recesses penetrating through two opposite sides of the bottom surface and the front surface of the base portion, a rear edge of the first main plate is bent upward to form a first bending plate, two opposite sides of a top edge of the first bending plate are slantwise extended upward and rearward to form two first resilient arms, a rear edge of the second main plate is bent downward to form a second bending plate, two opposite sides of a bottom edge of the second bending plate are slantwise extended downward and rearward to form two second resilient arms, the two first resilient arms are resiliently disposed over the two first recesses, the two second resilient arms are resiliently disposed under the two second recesses.

11. The electrical connector as claimed in claim 10 , wherein the top surface of the base portion is concaved downward to form a first locking groove located between the two first recesses, the bottom surface of the base portion is concaved upward to form a second locking groove located between the two second recesses, a middle of the top edge of the first bending plate is bent rearward to form a first auxiliary plate, a middle of a rear edge of the first auxiliary plate extends downward to form a first locking portion, a middle of the bottom edge of the second bending plate is bent rearward to form a second auxiliary plate, a middle of a rear edge of the second auxiliary plate extends upward to form a second locking portion, the first locking portion is locked in the first locking groove, the second locking portion is locked in the second locking groove.

12. The electrical connector as claimed in claim 10 , further comprising an outer shielding shell surrounding the inner shielding shell assembly, the first resilient arms and the second resilient arms of the inner shielding shell assembly abutting against the outer shielding shell.

13. The electrical connector as claimed in claim 1 , further comprising an outer shielding shell, the outer shielding shell surrounding the insulating housing together with the middle shielding plate and the terminals.
