Electrical connector with two signal and two grounding contact ends alternately positioned in two rows

1. An electrical connector comprising:

a plurality of contacts having

contact ends positioned in two rows, and

terminating ends positioned in one row; and

a first grouping of the plurality of contacts which includes units of two differential signal carrying contacts having signal carrying

contact ends connected to two signal terminating ends on a one to one ratio, and

grounding contacts positioned adjacent to the signal carrying contacts and having grounding contact ends connected to grounding terminating ends with a number of grounding contact ends being greater than a number of grounding terminating ends;

wherein two of the signal carrying contact ends and two of the grounding contact ends are alternately positioned in the two rows such that the signal carrying contact ends are surrounded by the grounding contact ends.

2. The electrical connector according to claim 1 , wherein the units of signal carrying contact ends and the grounding contact ends are positioned such that the phases of the signal contact ends and the grounding contact ends alternate between the two rows so that the signal contact ends and the grounding contact ends in opposing rows face each other.

3. The electrical connector according to claim 1 , wherein two grounding contact ends are positioned adjacent to the two signal carrying contact ends.

4. The electrical connector according to claim 1 , further comprising a second grouping of the plurality of contacts having the same composition as the first grouping.

5. The electrical connector according to claim 4 , wherein the two grounding contact ends of the first grouping are positioned adjacent to two grounding contact ends of the second grouping.

6. The electrical connector according to claim 5 , wherein the two grounding contact ends of the first grouping and the two grounding contact ends of the second grouping are alternately positioned.

7. The electrical connector according to claim , wherein all of the grounding contact ends and all of the grounding terminating ends are connected to each other.

8. The electrical connector according to claim 1 , wherein the contact ends are divided into a plurality of contact end groups.

9. The electrical connector according to claim 8 , wherein each contact end group has eight contact ends positioned in two rows.

10. The electrical connector according to claim 9 , wherein each row includes four consecutive contact ends.

11. The electrical connector according to claim 9 , wherein each contact end group is connected to six contact terminating ends.

12. The electrical connector according to claim 11 , wherein each contact end group includes four grounding contact ends connected to two grounded terminating ends, and four signal contact ends connected with four signal terminating ends.

13. The electrical connector according to claim 12 , wherein each contact end group includes four signal contact ends connected with four signal terminating ends.

14. The electrical connector of claim 11 , wherein each contact end group includes three grounding contact ends connected to a first grounded terminating end, and one grounding contact end connected to second grounding terminating end.

15. The electrical connector according to claim 14 , wherein each contact end group includes four signal contact ends connected with four signal terminating ends.

16. The electrical connector according to claim 1 , wherein the contact ends are male-type contact ends.

17. The electrical connector according to claim 1 , wherein the contact ends are female-type contact ends.
