Abstract

An electrical connector system, comprising: an electrical connector; a plurality of wires extending from the connector and arranged in a plurality of twisted pairs; and an insert separating the wires defining each of the twisted pairs. A method of reducing cross-talk in an electrical connector system that produces an unwanted cross-talk, comprising the steps of: providing an electrical connector with a plurality of wires extending therefrom and arranged in a plurality of twisted pairs; providing an insert; placing the insert between the wires defining each of the twisted pairs. The insert causes the wires to produce a compensating cross-talk that offsets the unwanted cross-talk. A method of using an electrical connector that exhibits an acceptable level of cross-talk within a desired frequency range, comprising the steps of: providing an electrical connector system that is unable to exhibit the acceptable level of cross-talk within the desired frequency range, the system including: an electrical connector; and a plurality of wires extending from the connector and arranged in a plurality of twisted pairs; separating the wires defining each of the twisted pairs; and operating the connector system within the desired frequency range. As a result, the connector system exhibits the desired level of cross-talk.

Claims

1. An electrical connector system, comprising:

an electrical connector;

a plurality of wires extending from said connector and arranged in a plurality of twisted pairs; and

an insert separating said wires defining each of said twisted pairs.

2. The electrical connector system as recited in

claim 1

, wherein said insert includes opposed surfaces, and each of said wires of each of said twisted pairs correspond to a respective one of said surfaces of said insert.

3. The electrical connector system as recited in

claim 2

, wherein said opposed surfaces each include a groove, said wires being positioned within said grooves.

4. The electrical connector system as recited in

claim 3

, wherein said wires are arranged side-by-side within said grooves.

5. The electrical connector system as recited in

claim 3

, wherein said wires are superposed within said grooves.

6. The electrical connector system as recited in

claim 1

, wherein said twisted pairs have a plurality of twists, and one of said twists of at least one of said twisted pairs is located between said insert and said connector.

7. The electrical connector system as recited in

claim 1

, further comprising an electrical connector at an opposite end of said twisted pairs.

8. The electrical connector system as recited in

claim 1

, wherein said insert is positioned entirely outside of said connector.

9. A method of reducing cross-talk in an electrical connector system that produces an unwanted cross-talk, comprising the steps of:

providing an electrical connector with a plurality of wires extending therefrom and arranged in a plurality of twisted pairs;

providing an insert;

placing said insert between said wires defining each of said twisted pairs;

wherein said insert causes said wires to produce a compensating cross-talk that offsets said unwanted cross-talk.

10. The method as recited in

claim 9

, wherein the insert placing step includes the step of placing said insert entirely outside of said connector.

11. The method as recited in

claim 9

, wherein said twisted pairs includes twists, and the insert placing step includes the step of positioning one of said twists of at least one of said twisted pairs between said insert and said connector.

12. The method as recited in

claim 9

, wherein said insert includes opposed surfaces, and the insert placing step comprises placing each of said wires of each of said twisted pairs on respective surfaces of said insert.

13. The method as recited in

claim 12

, wherein said surfaces of said insert each include a groove, and the insert placing step includes placing said wires in said grooves.

14. The method as recited in

claim 13

, wherein said wires are placed side-by-side within said grooves.

15. The method as recited in

claim 13

, wherein said wires are superposed within said grooves.

16. In an electrical connector system having an electrical connector with at least two twisted pairs of wires extending therefrom, the improvement comprising an insert placed between said wires defining each of said twisted pairs.

17. The electrical connector as recited in

claim 16

, wherein said insert is entirely outside of said connector.

18. A method of using an electrical connector that exhibits an acceptable level of cross-talk within a desired frequency range, comprising the steps of:

providing an electrical connector system that is unable to exhibit said acceptable level of cross-talk within said desired frequency range, said system including;

an electrical connector; and

a plurality of wires extending from said connector and arranged in a plurality of twisted pairs;

separating said wires defining each of said twisted pairs; and

operating said connector system within said desired frequency range;

wherein said connector system exhibits said desired level of cross-talk.

19. The method as recited in

claim 18

, wherein said separating step includes the steps of:

providing an insert; and

placing said insert between selected ones of said wires.

20. The method as recited in

claim 19

, wherein said twisted pairs include twists, and the insert placing step includes the step of positioning one of said twists of at least one of said twisted pairs between said insert and said connector.
