Abstract

An electrical connector includes a body having a tongue, a pair of first differential signal terminals and a pair of second differential signal terminals fixed to the body, and a middle shielding sheet fixed to the tongue, and located between the first and second differential signal terminals. The tongue includes an upper surface having two depressed first receiving slots and a lower surface having two depressed second receiving slots. A first groove is depressed from each first receiving slot. A second groove is upward depressed from each second receiving slot. Each first differential signal terminal has a first contact portion fixed to and exposed from the upper surface of the tongue. Each second differential signal terminal has a second contact portion fixed to and exposed from the lower surface of the tongue. The first and second contact portions are partially accommodated in the first and second receiving slot respectively.

First claim

What is claimed is:

1. An electrical connector, comprising:
a body having a tongue extending along a direction from front to rear, wherein the tongue comprises an upper surface and a lower surface opposite to each other, two first receiving slots are depressed from the upper surface, a first groove is downward depressed from the upper surface from each of the first receiving slots, two second receiving slots are depressed from the lower surface, and a second groove is upward depressed from the lower surface from each of the second receiving slots;
a pair of first differential signal terminals fixed to the body, wherein each of the first differential signal terminals has a first contact portion fixed to and exposed from the upper surface of the tongue, and the first contact portion is partially accommodated in the first receiving slot;
a pair of second differential signal terminals fixed to the body, wherein each of the second differential signal terminals has a second contact portion fixed to and exposed from the lower surface of the tongue, and the second contact portion is partially accommodated in the second receiving slot; and
a middle shielding sheet, fixedly disposed at the tongue, and located between the first differential signal terminals and the second differential signal terminals.

2. The electrical connector according to claim 1 , wherein the first receiving slot has a bottom wall supporting the first contact portion.

3. The electrical connector according to claim 2 , wherein the first contact portion has a first contact location used for contacting a mating element, and the bottom wall is located right below the first contact location.

4. The electrical connector according to claim 1 , wherein the second receiving slot has a top wall supporting the second contact portion.

5. The electrical connector according to claim 4 , wherein the second contact portion has a second contact location used for contacting a mating element, and the top wall is located right above the second contact location.

6. The electrical connector according to claim 1 , wherein the middle shielding sheet comprises a hollow portion corresponding to locations of the first groove and the second groove, and the first groove is in communication with the second groove.

7. The electrical connector according to claim 1 , wherein both the middle shielding sheet and the first differential signal terminals are insert-molded in the tongue, and the second differential signal terminals are assembled to the lower surface.

8. The electrical connector according to claim 1 , wherein the first contact portion is at least partially exposed to the first groove, and the second contact portion is at least partially exposed to the second groove.

9. The electrical connector according to claim 1 , further comprising a depressed slot depressed from the upper surface and located between two first differential signal terminals, wherein the depressed slot is in communication with two adjacent first receiving slots.

10. The electrical connector according to claim 9 , wherein multiple non-high-speed terminals are further insert-molded in the upper surface of the tongue, the non-high-speed terminals and the pair of first differential signal terminals are arranged into a row, multiple first receiving slots correspondingly accommodating the non-high-speed terminals are additionally depressed from the upper surface, multiple positioning slots are further depressed from the upper surface, the positioning slots are located between two adjacent non-high-speed terminals and between a non-high-speed terminal and a first differential signal terminal adjacent to each other, and the positioning slots are in communication with two adjacent first receiving slots.

11. The electrical connector according to claim 10 , wherein the length of at least one positioning slot along the direction from front to rear is less than the length of the depressed slot along the direction from front to rear.

12. The electrical connector according to claim 1 , wherein the tongue has a direction from left to right perpendicular to the direction from front to rear and a direction from top to bottom, the width of the first receiving slot in the direction from left to right is greater than the width of the first groove, and the width of the second receiving slot in the direction from left to right is greater than the width of the second groove.

13. An electrical connector, comprising:
a body having a tongue extending along a direction from front to rear, wherein the tongue comprises an upper surface and a lower surface opposite to each other, four first receiving slots are depressed from the upper surface, a first groove is downward depressed from the upper surface from each of the first receiving slots, four second receiving slots are depressed from the lower surface, and a second groove is further upward depressed from the lower surface from each of the second receiving slots;
two pairs of first differential signal terminals fixed to the body, wherein each of the first differential signal terminals has a first contact portion fixed to and exposed from the upper surface of the tongue, and the first contact portion is partially accommodated in the first receiving slot;
two pairs of second differential signal terminals fixed to the body, wherein each of the second differential signal terminals has a second contact portion fixed to and exposed from the lower surface of the tongue, and the second contact portion is partially accommodated in the second receiving slot; and
two pair of third signal terminals each respectively disposed between each of the two pairs of first differential signal terminals and each of the two pairs of second differential signal terminals, the third signal terminals are non-high-speed terminals, and a grounding terminal is disposed at an outer side of each of the two pairs of first differential signal terminals and the two pairs of second differential signal terminals away from the third signal terminals.

14. The electrical connector according to claim 13 , further comprising a middle shielding sheet fixedly disposed at the tongue, and located between the first differential signal terminals and the second differential signal terminals.

15. The electrical connector according to claim 14 , wherein the middle shielding sheet comprises a hollow portion corresponding to locations of the first groove and the second groove, and the first groove is in communication with the second groove.

16. The electrical connector according to claim 14 , wherein both the middle shielding sheet and the first differential signal terminals are insert-molded in the tongue, and the second differential signal terminals are assembled to the lower surface.

17. The electrical connector according to claim 14 , wherein the middle shielding sheet protrudes from a front edge and left and right side edges of the tongue.

18. The electrical connector according to claim 13 , further comprising multiple power supply terminals and multiple reserved terminals, wherein all of the foregoing terminals are arranged into two rows respectively located on the upper surface and the lower surface, and each row of terminals is sequentially provided in a direction from left to right with: one of the grounding terminals, one of the pairs of first differential signal terminals, one of the power supply terminals, one of the reserved terminals, one of the pairs of third signal terminals, one of the reserved terminals, one of the power supply terminals, one of the pairs of first differenti
