Abstract

An electrical connector includes an insulating body, a middle shielding sheet disposed in the insulating body, at least one row of terminals disposed in the insulating body and located on one side of the middle shielding sheet, an inner metal shell arranged on the insulating body, and an outer metal shell, enclosing the insulating body and the inner metal shell to form a mating cavity. The row of terminals includes at least one ground terminal. The ground terminal is projected laterally to form an urging portion. The inner metal shell at least partially encloses the terminals and the middle shielding sheet, and is in contact with the plate edge of the urging portion.

First claim

What is claimed is:

1. An electrical connector, comprising:
an insulating body;
a middle shielding sheet disposed in the insulating body;
at least one row of terminals disposed in the insulating body and located on one side of the middle shielding sheet, wherein the at least one row of terminals comprises at least one ground terminal, and the at least one ground terminal protrudes laterally to form an urging portion;
an inner metal shell arranged on the insulating body, the inner metal shell at least partially enclosing the terminals and the middle shielding sheet, and the inner metal shell being in contact with a plate edge of the urging portion; and
an outer metal shell, enclosing the insulating body and the inner metal shell to form a mating cavity.

2. The electrical connector of claim 1 , wherein the urging portion is connected with the inner metal shell by spot welding.

3. The electrical connector of claim 1 , wherein a sheet metal is blanked to form the ground terminal, the urging portion is formed integrally during blanking, and the plate edge of the urging portion is in contact with an inner wall of the inner metal shell.

4. The electrical connector of claim 1 , wherein the inner metal shell is provided with a sidewall embedded in the insulating body, and the urging portion is in contact with the sidewall in the insulating body.

5. The electrical connector of claim 1 , wherein the inner metal shell is provided with a sidewall exposed outside the insulating body, and the urging portion protrudes out of the insulating body to be in contact with the sidewall.

6. The electrical connector of claim 1 , further comprising an upper insulator and a lower insulator, wherein the at least one row of terminals comprises an upper row of terminals and a lower row of terminals, the upper row of terminals are insert-molded into the upper insulator to form a first terminal module, the lower row of terminals are insert-molded into the lower insulator to form a second terminal module, the insulating body is formed by the first terminal module and the second terminal module along with the middle shielding sheet by insert molding again, and the insulating body wraps the first terminal module, the second terminal module and the middle shielding sheet.

7. The electrical connector of claim 1 , wherein each of two sides of the middle shielding sheet is projected laterally to form a contact portion to be in contact with the inner metal shell, the contact portions are formed integrally when a sheet metal is blanked, and plate edges of the contact portions urge against the inner wall of the inner metal shell.

8. The electrical connector of claim 1 , wherein among the at least one row of terminals, outermost terminals located at both sides are ground terminals.

9. The electrical connector of claim 1 , wherein the insulating body comprises a base and a tongue extending forward from the base, and the urging portion is at least partially located in the base.

10. The electrical connector of claim 9 , wherein the ground terminal comprises a main body located in the base, and the urging portion extends outward from the main body along a direction perpendicular to the main body.

11. An electrical connector, comprising:
an insulating body extending along the longitudinal direction;
an inner metal shell fixed on the insulating body;
a plurality of terminals disposed in the insulating body and comprising at least one ground terminal, wherein the ground terminal is horizontally projected outward to form an urging portion, and the urging portions are in contact with the inner metal shell; and
an outer metal shell, enclosing the insulating body and the inner metal shell to form a mating cavity.

12. The electrical connector of claim 11 , wherein the urging portion is connected with the inner metal shell by spot welding.

13. The electrical connector of claim 11 , wherein a sheet metal is blanked to form the at least one ground terminal, the urging portion is formed integrally during blanking, and a plate edge of the urging portion is in contact with the inner wall of the inner metal shell.

14. The electrical connector of claim 11 , wherein the at least one ground terminal comprises a main body extending along the longitudinal direction, and the urging portion extends perpendicular to the main body, and is coplanar with the main body.

15. The electrical connector of claim 11 , wherein
the insulating body comprises a base and a tongue extending forward from the base; and
the inner metal shell comprises an annular portion fixed on the base and two covering portions extending forward from the annular portion, the two covering portions respectively cover an upper surface and a lower surface of the tongue, and the urging portion rigidly urges against the inner wall of the annular portion.

16. The electrical connector of claim 11 , wherein the plurality of terminals are arranged in an upper row and a lower row, a middle shielding sheet is disposed between the upper row of terminals and the lower row of terminals, and plate edges of both sides of the middle shielding sheet are respectively projected horizontally to be in rigid contact with the inner metal shell.
