Abstract

An electrical connector including a housing and electrical conductor plating. The housing includes a first member and a second member. The first member is made of plastic and forms at least one first contact receiving channel therein. The second member is attached around the first member, and the first and second members form at least one second contact receiving channel therebetween. The electrical conductor plating is on the first member. The electrical conductor plating includes at least one first section along the at least one first contact receiving channel and at least one second section along an exterior side of the first member at the at least one second contact receiving channel. The first and second sections of the electrical conductor plating are electrically separate from one another.

First claim

What is claimed is:

1. An electrical connector comprising:
a housing comprising a first member and a second member, where the first member is made of plastic and forms at least one first contact receiving channel therein, where the second member is attached around the first member, and where the first and second members form at least one second contact receiving channel therebetween; and
electrical conductor plating on the first member, where the electrical conductor plating comprises at least one first section along the at least one first contact receiving channel and at least one second section along an exterior side of the first member at the at least one second contact receiving channel, and where the first and second sections of the electrical conductor plating are electrically separate from one another.

2. An electrical connector comprising:
a housing comprising a first member made of an electrically insulative material that forms at least one first contact receiving channel therein; and
electrical conductor plating on the first member, where the electrical conductor plating comprises at least one first section along the at least one first contact receiving channel and at least one second section along an exterior side of the first member where the first and second sections of the electrical conductor plating are electrically separate from one another.

3. The electrical connector as claimed in claim 2 wherein the at least one first section is configured to transmit signals.

4. The electrical connector as claimed in claim 3 wherein the at least one second section is configured to be electrically connected to one of power or ground.

5. The electrical connector as claimed in claim 2 wherein the at least one first contact receiving channel defines two contact receiving channels that are electrically isolated from one another.

6. The electrical connector as claimed in claim 5 wherein the two contact receiving channels are configured to carry differential signals and have a differential impedance of 100±10 Ohms or 85±10 Ohms.

7. The electrical connector as claimed in claim 6 , wherein the differential impedance does not change even if there are no connector pins received in one or both of the two contact receiving channels.

8. The electrical connector as claimed in claim 2 further comprising a second member, wherein the second member is attached around the first member, and where-the first and second members form at least one second contact receiving channel therebetween.

9. The electrical connector as claimed in claim 5 , wherein the two contact receiving channels are C-shaped and are oriented in a mirror image with respect to one another.

10. The electrical connector as claimed in claim 9 , wherein the C-shaped two contact receiving channels are oriented back-to-back with openings extending away from each other.

11. The electrical connector as claimed in claim 1 wherein the housing is mechanically flexible.

12. The electrical connector as claimed in claim 1 wherein the housing is part of an electrical cable assembly.

13. An electrical connector comprising:
a housing comprising a first member made of plastic that forms at least one first contact receiving channel therein, the at least one first contact receiving channel defined by only three closed walls to form a partially open C-shaped cavity; and
electrical conductor plating on the first member, where the electrical conductor plating comprises at least one first section along the at least one first contact receiving channel and at least one second section along an exterior side of the first member at an at least one second contact receiving channel,
wherein the first and second sections of the electrical conductor plating are electrically separate.

14. The electrical connector as claimed in claim 13 wherein the at least one first section is configured to transmit signals.

15. The electrical connector as claimed in claim 13 wherein the at least one second section is configured to be electrically connected to one of power or ground.

16. The electrical connector as claimed in claim 13 wherein the at least one first contact receiving channel defines two contact receiving channels that are electrically isolated from one another.

17. The electrical connector as claimed in claim 16 wherein the two contact receiving channels are configured to carry differential signals and have a differential impedance of 100±10 Ohms or 85±10 Ohms.

18. The electrical connector as claimed in claim 17 , wherein the differential impedance does not change even if there are no connector pins received in one or both of the two contact receiving channels.

19. The electrical connector as claimed in claim 13 further comprising
a second member, wherein the second member is attached around the first member, and where the first and second members form at least one second contact receiving channel therebetween.

20. The electrical connector as claimed in claim 16 , wherein the two contact receiving channels are C-shaped and are oriented in a mirror image with respect to one another.

21. The electrical connector as claimed in claim 20 , wherein the C-shaped two contact receiving channels are oriented back-to-back with openings extending away from each other.

22. The electrical connector as claimed in claim 13 wherein the housing is mechanically flexible.

23. The electrical connector as claimed in claim 13 wherein the housing is part of an electrical cable assembly.

24. A method for connecting a mating electrical connector to an electrical connector, wherein the electrical connector comprises a first member, wherein the first member comprises electrically insulative material and has an elongated first section of electrical conductor plated thereon, the elongated first section being elongated in a first direction, and the method comprises:
inserting a conductive element from the mating electrical connector into the electrical connector, wherein the at least one conductive element is elongated in the first direction;
urging the first member towards the conductive element from the mating electrical connector such that the elongated first section contacts the conductive element.

25. The method of claim 24 , wherein:
urging the first member towards the conductive element comprises generating a spring force on the first member with a second member at least partially encircling the first member.

26. The method of claim 25 , wherein:
the conductive element comprises a first conductive element having a first width;
the mating electrical connector comprises a second conductive element having a second width, greater than the first width;
the first section of electrical conductor is on a first surface of the first member;
the first member comprises a second surface facing the second member;
the method comprises inserting the second conductive element between the second surface of the first member and the second member.

27. The method of claim 26 , wherein:
the second surface is plated with a second section of electrical conductor, electrically insulated within the electrical connector from the elongated first section; and
generating a spring force on the first member with a second member at least partially encircling the first member further comprises urging the second member towards second section.
