Abstract

An electrical connector includes an insulating body, a shielding sheet provided in the insulating body, at least one row of terminals accommodated in the insulating body and located on one side of the shielding sheet, a shielding shell sleeved outside the insulating body, and a first grounding portion. The terminals include at least one ground terminal. The shielding shell has an upper wall and a lower wall opposite to each other and two side walls connected to the upper wall and the lower wall. At least one of the side walls is provided with at least one elastic portion. The first grounding portion extends from the at least one ground terminal or from the shielding sheet toward a side thereof. The first grounding portion is provided with a cutting surface, which is exposed from the insulating body and elastically abuts an inner wall surface of the elastic portion.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulating body;
a shielding sheet provided in the insulating body;
a plurality of terminals, accommodated in the insulating body and provided in an upper row and a lower row, and comprising at least two ground terminals provided in the upper row and the lower row, wherein the shielding sheet is located between the ground terminals in the upper row and the lower row, each of the ground terminals in one row of the upper row and the lower row is provided with a first grounding portion, each of the ground terminals in the other row of the upper row and the lower row is provided with a second grounding portion, and the first grounding portion and the second grounding portion are in lap joint contact; and
a shielding shell sleeved outside the insulating body and having an upper wall and a lower wall opposite to each other and two side walls connected to the upper wall and the lower wall respectively, wherein at least one of the two side walls is provided with at least one elastic portion;
wherein the first grounding portion is provided with a cutting surface, and the cutting surface is exposed from the insulating body and elastically abuts an inner wall surface of the at least one elastic portion,
wherein the first grounding portion comprises:
a first extending section laterally extending from the ground terminal in the one row; and
a second extending section bending backward and extending from the first extending section;

wherein the second grounding portion comprises:
a bending section extending from the ground terminal in the other row of the upper row and the lower row toward the ground terminal in the one row of the upper row and the lower row;
a third extending section laterally extending from the bending section; and
a fourth extending section bending backward and extending from the third extending section;

wherein the first extending section and the third extending section are in surface attachment contact with each other, and the second extending section and the fourth extending section are in surface attachment contact with each other.

2. The electrical connector according to claim 1 , wherein at least one through slot is provided on at least one of the side walls, the through slot has a first slot wall and a second slot wall provided opposite to each other, the elastic portion is connected to the second slot wall and extends toward the first slot wall from the second slot wall, and a free end of the elastic portion is disconnected from the first slot wall.

3. The electrical connector according to claim 2 , wherein the first slot wall and the second slot wall are provided opposite to each other in a front-rear direction.

4. The electrical connector according to claim 2 , wherein the second slot wall is provided to be spaced apart from a rear edge of the lower wall.

5. The electrical connector according to claim 2 , wherein a metal shell is sleeved on the shielding shell, and the metal shell covers the through slot and the elastic portion.

6. The electrical connector according to claim 5 , wherein:
a side surface of the metal shell is provided with at least one first locking portion, and the side walls are correspondingly provided with at least one second locking portion configured to be matched with the at least one first locking portion;
the second slot wall comprises an upper slot wall and a lower slot wall spaced apart from each other by the elastic portion; and
a distance between the upper slot wall and the second locking portion is greater than a distance between the lower slot wall and the second locking portion.

7. The electrical connector according to claim 1 , wherein a free end of the elastic portion is inclined toward a direction close to the first grounding portion.

8. The electrical connector according to claim 1 , wherein the second extending section laterally extends to form a protruding portion, and the cutting surface is provided on the protruding portion and configured to be in contact with the inner wall surface of the elastic portion.

9. The electrical connector according to claim 1 , wherein the shielding sheet comprises a plate body and at least one abutting portion extending from the plate body toward a side thereof, and the abutting portion is exposed from the insulating body and is in rigid contact with the side walls.

10. The electrical connector according to claim 9 , wherein the first grounding portion and the abutting portion are provided on a same side of the insulating body, and a height of the abutting portion is different from a height of the first grounding portion in a vertical direction.

11. The electrical connector according to claim 9 , wherein the insulating body comprises a base portion, the base portion is provided with a recess portion, and the first grounding portion and the abutting portion are located in the recess portion.

12. The electrical connector according to claim 9 , wherein a side surface of the metal shell is provided with at least one first locking portion, at least one of the side walls is provided with a connecting portion and at least one second locking portion located behind the elastic portion, the second locking portion is configured to be matched with the first locking portion, the connecting portion is connected to the second locking portion and the elastic portion, and the abutting portion is in rigid contact with the connecting portion.

13. An electrical connector, comprising:
an insulating body;
a plurality of terminals fixedly provided on the insulating body in an upper row and a lower row, and comprising at least two ground terminals provided in the upper row and the lower row, wherein each of the ground terminals in one row of the upper row and the lower row is provided with a first grounding portion, each of the ground terminals in the other row of the upper row and the lower row is provided with a second grounding portion, and the first grounding portion and the second grounding portion are in lap joint contact;
a shielding sheet embedded in the insulating body and located between the ground terminals in the upper row and the lower row; and
a shielding shell sleeved outside the insulating body and comprising two side walls in a lateral direction, wherein at least one of the two side walls is provided with at least one elastic portion, and the elastic portion has an elastic contact surface;
wherein the first grounding portion is exposed from the insulating body and abuts the elastic contact surface,
wherein the first grounding portion comprises:
a first extending section laterally extending from the ground terminal in the one row; and
a second extending section bending backward and extending from the first extending section;

wherein the second grounding portion comprises:
