Abstract

An electrical connector includes an insulating body provided with multiple accommodating holes penetrating through the insulating body vertically, multiple terminals used for contacting a chip module, and at least one shielding sheet accommodated in the insulating body. The accommodating holes include signal accommodating holes and ground accommodating holes. Each signal accommodating hole is provided with a stopping portion. The terminals include signal terminals accommodated in the signal accommodating holes and ground terminals accommodated in the ground accommodating holes. Each shielding sheet or each terminal is provided with an urging portion. The ground terminals and the shielding sheet contact each other through the urging portion, and the stopping portions stop the urging portion to prevent the signal terminals and the shielding sheet from contacting each other.

First claim

What is claimed is:

1. An electrical connector, comprising:
an insulating body, provided with a plurality of accommodating holes penetrating through the insulating body vertically, the accommodating holes comprising signal accommodating holes and ground accommodating holes, wherein each of the signal accommodating holes is provided with a stopping portion;
a plurality of terminals, configured for contacting a chip module, and comprising signal terminals accommodated in the signal accommodating holes and ground terminals accommodated in the ground accommodating holes; and
at least one shielding sheet, accommodated in the insulating body;
wherein the at least one shielding sheet or each of the terminals is provided with an urging portion, the ground terminals and the at least one shielding sheet contact each other through the urging portion, and the stopping portions stop the urging portion to prevent the signal terminals and the at least one shielding sheet from contacting each other.

2. The electrical connector of claim 1 , wherein each of the signal terminals and each of the ground terminals are of a same structure and respectively provided with a connecting portion in a planar shape, and an upper elastic arm formed by bending and extending upward from the connecting portion, configured for conductively connected to the chip module.

3. The electrical connector of claim 2 , wherein a plurality of urging portions are provided, and the urging portions are only provided on the at least one shielding sheet.

4. The electrical connector of claim 3 , wherein the stopping portion of each of the signal accommodating holes is located between a corresponding one of the urging portions and the upper elastic arm of a corresponding one of the signal terminals, and the urging portion corresponding to each of the ground accommodating holes urges against the upper elastic arm of a corresponding one of the ground terminals.

5. The electrical connector of claim 3 , wherein a lower elastic arm is formed by bending and extending downward from the connecting portion, configured for conductively connected downward to a circuit board; the stopping portion of each of the signal accommodating holes is located between a corresponding one of the urging portions and the lower elastic arm of a corresponding one of the signal terminals, and the urging portion corresponding to each of the ground accommodating holes urges against the lower elastic arm of the ground terminals.

6. The electrical connector of claim 3 , wherein each of the signal terminals is farther away from the urging portions than each of the ground terminals.

7. The electrical connector of claim 3 , wherein each of the signal accommodating holes is farther away from the urging portions than each of the ground accommodating holes.

8. The electrical connector of claim 2 , wherein each of the signal accommodating holes and each of the ground accommodating holes are respectively provided with at least one position limiting portion located between the at least one shielding sheet and the upper elastic arm.

9. The electrical connector of claim 3 , wherein the shielding sheet has a flat portion located at one side of an edge of the connecting portion, each of the urging portions is formed by bending and extending from the flat portion, and a plate surface of each of the urging portions urges against an edge of a corresponding one of the ground terminals.

10. The electrical connector of claim 9 , wherein the upper elastic arm bends and extends from a top end of the connecting portion to one side of the flat portion, and then bends and extends to an opposite side of the flat portion.

11. The electrical connector of claim 9 , wherein a retaining portion is formed by extending from a side of the connecting portion opposite to the shielding sheet to be retained to the insulating body.

12. The electrical connector of claim 11 , wherein the retaining portion is parallel to a plate surface of the flat portion.

13. The electrical connector of claim 9 , further comprising a metal sheet having a planar base located below the flat portion, wherein a bottom end of the flat portion contacts a top end of the base.

14. The electrical connector of claim 13 , wherein a plurality of openings are concavely provided at the bottom end of the flat portion, an extending portion is formed by extending upward from the top end of the base to be accommodated in one of the openings, and a contact portion is formed by bending and extending upward from the extending portion to urge against a plate surface of the corresponding shielding sheet.

15. The electrical connector of claim 14 , wherein each of the urging portions is formed by bending and extending downward from one of the openings, and the contact portion urges against the plate surface of a corresponding one of the urging portions.

16. The electrical connector of claim 15 , wherein a protruding portion is protrudingly provided on a plate surface of the contact portion to urge against the plate surface of a corresponding one of the urging portions.

17. The electrical connector of claim 9 , wherein a notch is concavely provided at a top end of the flat portion, each of the urging portions is formed by bending and extending upward from the notch, and the plate surface of each of the urging portions urges against an edge of the upper elastic arm of a corresponding one of the ground terminals.

18. The electrical connector of claim 17 , wherein each of the urging portions has a connecting section formed by bending and extending from the notch toward the edge of the upper elastic arm, and an urging section formed by vertically extending upward from the connecting section, wherein a free end is formed by bending and extending from the urging section to be away from the edge of the upper elastic arm, and a plate surface of the urging section urges against the edge of the upper elastic arm.

19. The electrical connector of claim 1 , wherein the at least one shielding sheet corresponds to a row of the terminals, the insulating body is provided with an accommodating groove for accommodating the at least one shielding sheet, and the accommodating groove is communicated with the signal accommodating holes and the ground accommodating holes.

20. The electrical connector of claim 1 , wherein the shielding sheet is provided with a plurality of through slots, the insulating body is provided with a plurality of positioning portions accommodated in the through slots respectively, a partitioning wall is provided between each of two adjacent ones of the accommodating holes, and the partitioning wall and the positioning portions are arranged abreast.
