Abstract

An electrical connector system with adjusted impedance is described herein. The electrical connector system includes a cable having at least two conductors and a shell element provided at least partially around the cable. Further, the electrical connector system includes a connector housing assembly that is separate from the shell element and is configured to at least partially receive the two conductors and the shell element.

First claim

We claim:

1. An electrical connector system with adjusted impedance, comprising:
a cable having only two solid copper wires separated from one another;
a shell element provided at least partially around said cable; and
a connector housing assembly separate from the shell element and configured to at least partially receive the two solid copper wires and the shell element, wherein the shell element is provided such that it exerts a force on the cable to locally alter a distance between the two solid copper wires, and wherein the shell element comprises fixing means configured to fix the shell element to the cable, wherein said fixing means comprises a tooth-like projection.

2. An electrical connector system with adjusted impedance, comprising:
a cable having only two solid copper wires separated from one another;
a shell element provided at least partially around said cable; and
a connector housing assembly separate from the shell element and configured to at least partially receive the two solid copper wires and the shell element, wherein the shell element is provided such that it exerts a force on the cable to locally alter a distance between the two solid copper wires, wherein the connector housing assembly comprises a separate secondary lock member, and wherein the secondary lock member comprises fastening means for fastening the secondary lock member to the shell element and integrated locking means configured for locking the secondary lock member directly to a corresponding counter connector.

3. An electrical connector system with adjusted impedance, comprising:
a cable having at least two conductors;
a shell element provided at least partially around said cable; and
a connector housing assembly separate from the shell element and configured to at least partially receive the at least two conductors and the shell element, wherein the shell element is provided such that it exerts a force on the cable to locally alter a distance between the at least two conductors, wherein the shell element comprises fixing means configured to fix the shell element to the cable, wherein said fixing means comprises a tooth-like projection.

4. The electrical connector system in accordance with claim 3 , wherein the shell element comprises an indentation.

5. The electrical connector system in accordance with claim 4 , wherein a major direction of the indentation is oriented parallel to a longitudinal direction of the cable.

6. The electrical connector system in accordance with claim 4 , wherein the indentation extends along substantially an entire length of the shell element.

7. The electrical connector system in accordance with claim 3 , wherein the shell element is crimped onto said cable.

8. The electrical connector system in accordance with claim 3 , wherein the shell element is a ferrule.

9. The electrical connector system in accordance with claim 3 , wherein the shell element is provided on an end portion of the cable.

10. The electrical connector system in accordance with claim 3 , wherein the cable comprises a sheathing encompassing the at least two conductors, and wherein the shell element is provided on said sheathing.

11. The electrical connector system in accordance with claim 3 , wherein the shell element is provided such that it exerts the force on the cable to locally shorten the distance between the at least two conductors.

12. The electrical connector system in accordance with claim 3 , wherein the shell element is provided such that it exerts the force on the cable to locally alter the distance between the at least two conductors for adjusting an impedance of the electrical connector system.

13. The electrical connector system in accordance with claim 3 , further comprising a counter connector comprising an aperture configured to receive the connector housing assembly at least partially therein.

14. An electrical connector system with adjusted impedance, comprising:
a cable having at least two conductors;
a shell element provided at least partially around said cable; and
a connector housing assembly separate from the shell element and configured to at least partially receive the at least two conductors and the shell element, wherein the shell element is provided such that it exerts a force on the cable to locally alter a distance between the at least two conductors, wherein the connector housing assembly comprises a separate secondary lock member, wherein the secondary lock member comprises fastening means for fastening the secondary lock member to the shell element and integrated locking means configured for locking the secondary lock member directly to a corresponding counter connector.

15. The electrical connector system in accordance with claim 14 , wherein the shell element comprises at least one protrusion configured to be in blocking contact with a respective recess of the secondary lock member and wherein the secondary lock member comprises at least one protrusion configured to be in blocking contact with a respective recess of the shell element.

16. The electrical connector system in accordance with claim 14 , wherein the connector housing assembly comprises a connector housing configured to receive the at least two conductors at least partially, and wherein the shell element is not connected to the connector housing.

17. The electrical connector system in accordance with claim 16 , wherein the secondary lock member comprises mounting means for mounting the secondary lock member to the connector housing, wherein the mounting means comprise at least one hook configured to envelope the connector housing at least partially when the secondary lock member is mounted thereto.

18. The electrical connector system in accordance with claim 14 , wherein the shell element comprises an indentation.

19. The electrical connector system in accordance with claim 18 , wherein a major direction of the indentation is oriented parallel to a longitudinal direction of the cable.

20. The electrical connector system in accordance with claim 18 , wherein the indentation extends along substantially an entire length of the shell element.

21. The electrical connector system in accordance with claim 14 , wherein the shell element is crimped onto said cable.

22. The electrical connector system in accordance with claim 14 , wherein the shell element is a ferrule.

23. The electrical connector system in accordance with claim 14 , wherein the shell element is provided on an end portion of the cable.

24. The electrical connector system in accordance with claim 14 , wherein the cable comprises a sheathing encompassing the at least two conductors, and wherein the shell element is provided on said sheathing.

25. The electrical connector system in accordance with claim 14 , wherein the shell element is provided such that it exerts the force on the cable to locally shorten the distance between the at least two conductors.

26. The electrical connector system in accordance with claim 14 , wherein the shell element is provided such that it exerts the force on the cable to locally alter the distance between the at least two conductors for adjusting an impedance of the electrical connector system.

27. The electrical connector system in accordance with claim 14 , further comprising a counter connector comprising an aperture configured to receive the connector housing assembly at least partially therein.
