1 and 2, the electrical connector 1 according to the present invention includes an insulating housing 10 having a tongue portion 11 protruding forward and a plurality of passages 110 defined therein, and a passage ( A plurality of terminals 20 received in the 110, two ground plates 21, a shield 30 surrounding the tongue 11 of the housing 10, a bracket 40 for supporting the insulating housing 10, and Two metal latches 50 are assembled with the elements. The passage 110 is defined through the main portion 12 of the housing 10 and extends along the bottom surface of the tongue 11. Three grooves 100 are defined at both sides and top of the tongue 11 at the front face of the main part 12. The through hole 102 is defined in the main portion 12 adjacent to each side end portion. The recesses 104 are defined at each side edge of the main portion 12. The protrusion 106 extends rearward from the main portion 12 and defines two inwardly extending slots 107 arranged perpendicular to the passageway 110 (see FIG. 3). Each slot 107 is adapted to connect with the ground plate 21.

Each ground plate 21 has an ear 210 which connects with the recess 104 of the housing 10 and an insert 214 which connects with the slot 107 of the housing 10. A hole 212 is defined in the center of the ground plate 21.

Each terminal 20 comprises a mating section 22 at its front end, a solder section 24 at its rear end, and an interference section 26 therebetween. The interference section 26 is coherently connected with the insulating housing 10, thereby fixing the terminal 20 in place.

The shield 30 has a rectangular shape for enclosing the tongue 11. Three tabs 300 extend outward from the rear edge of the shield 30 and are connected to the grooves 100 of the corresponding housing 10.

Bracket 40 has a plate 400 and a base plate 402 mated in an L-shape. The base plate 402 defines three holes 404 for the insertion of fastening means for fastening the connector to an outer body, such as a printed circuit board. The mating plate 400 defines an opening 401 for the extension of the shield 30 and the tongue 11. The mating plate 400 further defines a bore 403 at two opposing ends.

1 and 4, each latch 50 has a retaining portion 52 at the front end and an engaging portion 54 at the rear end. Coupling portion 54 has two spaced elastic arms 542 divided into channels (not shown). The retainer 52 has a baffle 522 at the front end and a connecting section 524 at the center and a fixing section 526 at the rear, where the diameter of the fixing section 526 is the diameter of the connecting section 524. Becomes smaller.

In assembly, the terminal 20 is inserted into the housing 10 from the rear side of the housing, with the solder section 24 protruding rearward from the housing 10. The shield 30 slides along the tongue 11 of the housing 10, with the tab 300 of the shield 30 being connected to the groove 100 of the housing 10. The ground plate 21 is connected to the housing 10 where the ear 210 is fitted to the corresponding recess 104 and the insert 214 is inserted into the corresponding slot 107 (see FIG. 3). ).
