Abstract

An electrical connector with a terminal module enclosed within an insulative shield wherein the terminal module includes a plurality of terminals embedded within an insulative main body. The insulative main body forms a rear mounting standing part and a front mating tongue part extending forwardly from the rear mounting standing part. The insulative shield forms a rearward step against a forward shoulder of the base portion so as to prevent further forward movement of the base portion relative to the insulative shield. The insulative main body forms a protrusion and the insulative shield forms a securing hole to receive said protrusion for securing the insulative shield and the terminal module together.

Claims

1. An electrical connector assembly comprising:

a terminal module including;

an insulative main body having a rear mounting standing part and a front mating tongue part extending forwardly from the rear mounting standing part;

a plurality of terminals disposed in the insulative main body, via at least one insert-molding process, with corresponding contacting sections exposed upon the front mating tongue part; and

an insulative shield assembled to the terminal module, and including a base and a tubular section extending forwardly from the base, wherein

the base of the insulative shield forms a pair of downwardly extending mounting legs by two lateral sides of the terminal module for securing to an external printed circuit board (PCB) on which the insulative shield is positioned.

2. The electrical connector assembly as claimed in claim 1, further including a metallic shielding plate embedded within the insulative main body with a pair of soldering legs located between the pair of mounting legs in a transverse direction.

3. The electrical connector assembly as claimed in claim 1, wherein said mounting legs are round to snugly comply with a configuration of a corresponding mounting hole in the PCB while said soldering leg of the shielding plate is of a blade type.

4. The electrical connector assembly as claimed in claim 1, wherein said base is of an upside-down U-shaped configuration to cover the rear mounting standing part.

5. The electrical connector assembly as claimed in claim 1, wherein said tubular section further includes a pair of wings extending outwardly laterally on two lateral sides thereof.

6. The electrical connector assembly as claimed in claim 1, wherein said tubular section forms a pair of securing holes in opposite lateral sides to receive corresponding protrusions on the insulative main body so as to secure the terminal module to the insulative shield.

7. The electrical connector assembly as claimed in claim 1, wherein a waterproof plate is formed by glue around a root of said front mating tongue part.

8. The electrical connector assembly as claimed in claim 1, wherein said terminal module includes a first terminal module with a plurality of first terminals integrally formed within a first insulative body, and a second terminal module with a plurality of second terminals integrally formed within a second insulative body, said first insulative body being assembled with the second insulative body with a metallic shielding plate therebetween in a vertical direction.

9. The electrical connector assembly as claimed in claim 7, wherein said terminal module further includes a third insulative body applied thereon to complete the front mating tongue part, and said insulative shield is secured to the terminal module through said third insulative body.

16. The electrical connector assembly as claimed in claim 9, wherein said mounting legs are of a round type while said soldering legs are of a blade type.

10. An electrical connector assembly comprising:

a printed circuit board forming a cutout, a pair of large mounting holes located by two lateral sides of the cutout, and a pair of small mounting holes and a pair of soldering holes both located at a rear side of the cutout wherein said pair of soldering holes are located between the pair of small mounting holes in a transverse direction;

an electrical connector including;

a terminal module received within an insulative shield, said terminal module including a plurality of terminals and a metallic shielding plate integrally formed within an insulative main body via at least one insert-molding process, said insulative shield including a base and a tubular section extending from said base;

wherein

the tubular section is located within the cutout and the base is positioned upon the printed circuit board;

wherein

said base forms a pair of mounting legs extending through the corresponding small mounting holes, respectively, in a vertical direction, and said shielding plate forms a pair of soldering legs extending through the corresponding soldering holes.

11. The electrical connector assembly as claimed in claim 10, wherein the tubular section forms a pair of wings with corresponding large securing holes aligned with the pair of large mounting holes, respectively, in said vertical direction,

12. The electrical connector assembly as claimed in claim 10, wherein said terminal module includes a first terminal module and a second terminal module commonly sandwiching the shielding plate therebetween in the vertical direction.

13. The electrical connector assembly as claimed in claim 12, wherein said first terminal module includes a plurality of first terminals integrally formed within a first insulative body, and said second terminal module includes a plurality of second terminals integrally formed within a second insulative body, and a third insulative body applied upon both said first terminal module and said second terminal module.

14. The electrical connector assembly as claimed in claim 10, wherein the insulative main body of the terminal module forms a protrusion, and the insulative shield forms a securing hole to receive said protrusion for securing the terminal module within the insulative shielding.

15. The electrical connector assembly as claimed in claim 10, wherein a waterproof plate is formed in the terminal module around a boundary between the tubular section and the base.

17. An electrical connector for securing to a printed circuit board, comprising:

a terminal module including;

an insulative main body having a rear mounting standing part and a front mating tongue part extending forwardly from the rear mounting standing part;

a plurality of terminals and a metallic shielding plate commonly disposed in the insulative main body, via at least one insert-molding process, with corresponding contacting sections exposed upon the front mating tongue part, and with a pair of soldering legs extending downwardly from a rear region of the shielding plate; and

an insulative shield assembled to the terminal module, and including a base and a tubular section extending forwardly from the base, wherein

the base of the insulative shield forms a pair of downwardly extending mounting legs for mounting to an external printed circuit board (PCB) on which the insulative shield is positioned;

wherein

said mounting legs are of a round type while said soldering legs are of a blade type.

18. The electrical connector assembly as claimed in claim 17, wherein said tubular section forms a pair of outwardly and laterally extending wings with corresponding securing holes, said holes are diametrically larger than the mounting legs.

19. The electrical connector assembly as claimed in claim 17, wherein the insulative shield forms a securing hole to receive a protrusion of the insulative main body for securing the terminal module and the insulative shield together.

20. The electrical connector assembly as claimed in claim 17, wherein a waterproof plate is disposed in the terminal module and located adjacent to a boundary between the tubular section and the base.
