[0022] Please see Figures 1 to 5As shown, a preferred embodiment of the present invention discloses an electrical connector 100, which is a Type-C connector with high-speed data transmission performance. The electrical connector 100 includes an insulating body 10 and a plurality of conductive terminals 20, an intermediate shielding sheet 30, and a pair of grounding members 40 fixed to the insulating body 10.

[0023] The insulating body 10 has a base 11 extending laterally, a tongue portion 12 extending longitudinally forward from the base 11, and a stepped portion 13 located between the base 11 and the tongue portion 12. There is a height difference between the stepped portion 13 and both the base 11 and the tongue portion 12. The conductive terminal 20 includes an upper row of terminals 21 and a lower row of terminals 22, which are respectively partially exposed on the upper and lower surfaces of the tongue portion 12. The intermediate shielding sheet 30 is located between the upper row of terminals 21 and the lower row of terminals 22. Specifically, the conductive terminal 20 has a holding portion fixed within the stepped portion 13, a contact portion extending longitudinally forward from the holding portion, and a connecting portion extending longitudinally backward from the holding portion. The contact portions of the upper row of terminals 21 are exposed on the upper surface of the tongue portion 12, and the contact portions of the lower row of terminals 22 are exposed on the lower surface of the tongue portion 12.

[0024] Furthermore, the insulating body 10 is provided with an upper insulator 101, a lower insulator 102, a front insulator 103, and a rear insulator 104. The upper insulator 101 is integrally injection molded onto the upper row of terminals 21 to form an upper terminal group, and the lower insulator 102 is integrally injection molded onto the lower row of terminals 22 to form a lower terminal group. The intermediate shielding sheet 30 is sandwiched between the upper terminal group and the lower terminal group, and the front insulator 103 is integrally injection molded onto the upper terminal group, the intermediate shielding sheet 30, and the lower terminal group to form a terminal module. At this time, the connection portion of the conductive terminal 20 is exposed on the longitudinal rear side of the terminal module. Finally, the rear insulator 104 is integrally injection molded onto the longitudinal rear end of the terminal module to form the aforementioned electrical connector 100. At this time, the connection portion of the conductive terminal 20 is embedded in the rear insulator 104.

[0025] Combination Figure 3 and Figure 4As shown, the intermediate shielding sheet 30 has a plate-shaped flat plate portion 31, an extension portion 32 extending laterally outward from the rear end of the flat plate portion 31, a vertical portion 33 located on the outer side of the front end of the flat plate portion 31, and a reinforcing portion 34 connected to the extension portion 32. The flat plate portion 31 is located between the upper row of terminals 21 and the lower row of terminals 22. The flat plate portion 31 has a front section portion 311 fixed in the tongue plate portion 12, a middle section portion 312 fixed in the stepped portion 13, and a rear section portion 313 fixed in the base portion 11. The extension portion 32 extends laterally outward from both sides of the rear section portion 313 and is embedded in the base portion 11. At the same time, the flat plate portion 31 has through holes 310 in the front section portion 311, the middle section portion 312, and the rear section portion 313 to better secure the intermediate shielding sheet 30 within the insulating body 10.

[0026] The vertical part 33 is arranged perpendicular to the flat plate part 31. The vertical part 33 is provided with a bent part 331 that bends upward from the two sides of the middle section 312 of the flat plate part 31, an outer stop part 332 that extends forward longitudinally from the bent part 331, a front stop part 333 that bends inward from the longitudinal front end of the outer stop part 332, and a rear stop part 334 that bends outward from the longitudinal rear end of the bent part 331. The bent part 331 is embedded in the stepped part 13 of the insulating body 10.

[0027] The outer stop portion 332 is torn downward from the front section portion 311 and extends downward beyond the front section portion 311, forming a notch 314 between the outer stop portion 332 and the front section portion 311. The outer stop portion 332 is exposed on the outer surfaces of both lateral sides of the tongue plate portion 12, which strengthens the lateral outer surface of the tongue plate portion 12 and allows contact with the mating shield of the mating connector, thereby preventing wear on the tongue plate portion 12 of the insulating body 10. The front stop portion 333 extends laterally inward beyond the notch 314 and abuts against the longitudinal front end of the front section portion 311. At the same time, the front stop portion 333 is embedded in the tongue plate portion 12 to increase the strength of the longitudinal front end of the tongue plate portion 12. The rear stop portion 334 extends to the longitudinal front end of the extension portion 32 and is embedded in the base portion 11.

[0028] The reinforcing portion 34 and the extension portion 32 are both located on the lateral sides of the conductive terminal 20. The reinforcing portion 34 has a rear wall portion 341 that bends upward from the longitudinal rear end of the extension portion 32, an outer wall portion 342 that bends forward from the lateral outer side of the rear wall portion 341, a bottom wall portion 343 that extends laterally inward from the bottom of the outer wall portion 342, and a front wall portion 344 that bends laterally inward from the longitudinal front end of the outer wall portion 342. The rear wall portion 341 is embedded in the base 11. The outer wall portion 342 extends vertically and downward beyond the flat plate portion 31 and the extension portion 32. A gap is formed between the outer wall portion 342 and the extension portion 32, and the outer wall portion 342 is exposed on the outer surfaces of the lateral sides of the base 11. When the electrical connector 100 is equipped with a metal shell, the outer wall portion 342 can contact the inner wall of the metal shell to form a better electromagnetic shielding effect.

[0029] The bottom wall portion 343 is located below the extension portion 32 and embedded within the base portion 11 to further enhance the connection between the reinforcing portion 34 and the base portion 11, and to increase the strength of the lateral sides of the base portion 11. The front wall portion 344 is located at the longitudinal front end of the extension portion 32 and welded to the rear stop portion of the vertical portion 33, that is, the rear stop portion 334 and the front wall portion 344 are welded together; and the front wall portion 344 is embedded within the base portion 11. The reinforcing portion 34 is spot-welded to the vertical portion 33 on the flat plate portion 31 by the front wall portion 344 to increase the lateral strength of the intermediate shielding plate 30, reduce the risk of tearing in outward pulling tests, and thus meet the requirements of more stringent tests.

[0030] A pair of grounding plates 40 are respectively disposed on the upper and lower surfaces of the stepped portion 13 of the insulating body 10, and the lateral sides of the grounding plates 40 are bent and extended until they abut against the intermediate shielding plate 30, thereby forming better electromagnetic shielding on the outside of the conductive terminal 20. Figure 5 As shown, the electrical connector 100 further includes several external terminals 50 extending vertically and an insulating base 60 fixed to the lower end of the external terminals 50. The upper end of the external terminals 50 is fixed within the base 11 of the insulating body 10 and is correspondingly connected to the connecting portion at the longitudinal rear end of the conductive terminal 20. The lower end of the external terminals 50 is a soldering pin for soldering to a circuit board, thereby transmitting the signal on the conductive terminal 20 to the circuit board via the external terminals 50. The insulating base 60 is located above the soldering pin of the external terminals 50 and is fixed to the circuit board.

[0031] In this invention, the intermediate shielding sheet 30 includes an extension portion 32 extending laterally outward from the rear end of the flat plate portion 31, a vertical portion 33 located on the outer side of the front end of the flat plate portion 31, and a reinforcing portion 34 connected to the extension portion 32. The vertical portion 33 is perpendicular to the flat plate portion 31 and extends to the longitudinal front end of the extension portion 32. The reinforcing portion 34 includes a rear wall portion 341 extending upwardly from the longitudinal rear end of the extension portion 32, an outer wall portion 342 extending forwardly from the lateral outer side of the rear wall portion 341, and a front wall portion 344 extending laterally inward from the longitudinal front end of the outer wall portion 342. The front wall portion 344 is located at the longitudinal front end of the extension portion 32 and welded to the vertical portion 33. The reinforcing portion 32 is spot-welded to the flat plate portion 31 via the front wall portion 344 to increase the lateral strength of the intermediate shielding sheet 30, reduce the risk of tearing during outward pulling tests, and thus meet the requirements of more stringent tests.
