Abstract

The invention relates to an arrangement of at least two contact pairs (1, 2; 3, 4) for compensation of near-end crosstalk, in which one or both contacts (1, 2 or 3, 4) of a contact pair (1, 2; 3, 4) are designed to be angled away once or more than once from a contact region (5), with the result that the contacts (1, 2 and 3, 4) then run parallel once more and the distance between the contacts (1, 3 and 2, 4) of different contact pairs is designed such that crosstalk which is in antiphase with the contact region (5) is produced.

Claims

1. An arrangement of at least two contact pairs, comprising:

a contact region formed by individual contacts of the contact pairs;

at least one contact of a contact pair having an angled away portion, angled away at least once from the contact region;

a parallel run region provided after said angled away portion;

a distance between the contacts of different contact pairs in said parallel run region being set to provide crosstalk which is in antiphase with crosstalk of said contact region; and

a compensation region, said parallel run region forming at least a part of said compensation region said contact zone forming part of said compensation region.

2. The arrangement according to claim 1, wherein the contacts of the contact pair are arranged symmetrically beside one another in said contact region, said parallel run region forming at least a part of a compensation region and the distance in the compensation region between the contacts of different contact pairs is smaller than the distance between the contacts of a contact pair.

3. The arrangement according to claim 1, wherein the contacts of the contact pair are arranged nested in one another symmetrically in the contact region, said parallel run region forming at least a part of a compensation region and in the compensation region the planes covered between the contacts include an angle a<

90°

.

4. The arrangement according to claim 1, wherein said contacts are designed such that they are at least partially flattened.

5. The arrangement according to claim 1, wherein said contacts, following a equidirectional extension portion, are designed such that they are angled away toward an associated contact of each contact pair, with the result that the smaller distance between the contacts produces crosstalk which is in phase with the contact region.

6. An arrangement of at least two contact pairs, comprising:

a contact region formed by individual contacts of the contact pairs, said contacts of each contact pair extending in opposite directions from the contact region;

each contact pair having an angled away portion, angled away at least once from the contact region in the same direction;

a parallel run region provided after said angled away portion; and

a distance between the contacts of different contact pairs in said parallel run region set to provide crosstalk which is in antiphase with crosstalk of said contact region.

7. An arrangement of at least two contact pairs, comprising:

a contact region formed by individual contacts of the contact pairs;

at least one contact of a contact pair having an angled away portion, angled away at least once from the contact region;

a parallel run region provided after said angled away portion; and

a distance between the contacts of different contact pairs in said parallel run region being set to provide crosstalk which is in antiphase with crosstalk of said contact region, wherein the contacts of each contact pair are designed to be equidirectional and parallel in the contact region.

8. An arrangement of at least two contact pairs, comprising:

a contact region formed by individual contacts of the contact pairs;

at least one contact of a contact pair having an angled away portion, angled away at least once from the contact region;

a parallel run region provided after said angled away portion, and a distance between the contacts of different contact pairs in said parallel run region set to provide crosstalk which is in antiphase with crosstalk of said contact region, wherein the contacts of the contact pair are arranged to be parallel and in mutually opposite directions in the contact region.

9. An arrangement of at least two contact pairs, comprising:

a contact region formed by individual contacts of the contact pairs;

at least one contact of a contact pair having an angled away portion, angled away at least once from the contact region;

a parallel run region provided after said angled away portion; and

a distance between the contacts of different contact pairs in said parallel run region set to provide crosstalk which is in antiphase with crosstalk of said contact region, said parallel run region forming at least a part of a compensation region, in order to limit the compensation region, the contacts extending in a decoupled position with respect to one another.

10. An arrangement of at least two contact pairs, comprising:

contact region formed by individual contacts of the contact pairs;

at least one contact of a contact pair having an angled away portion, angled away at least once from the contact region;

a parallel run region provided after said angled away portion; and

a distance between the contacts of different contact pairs in said parallel run region set to provide crosstalk which is in antiphase with crosstalk of said contact region, said contact pairs include four contact pairs with an inner contact pair nested in another contact pair, wherein the associated contacts of the inner contact pair and said another contact pair are arranged to be parallel and extending in mutually opposite directions in said contact region and, following the contact region, are led in loops relative to one another.

11. The arrangement according to claim 10, wherein the contacts of a first outer contact pair of said contact pairs are arranged continuously parallel to one another, the contact being led, in the contact region, parallel and in the opposite direction to the next adjacent contact of the inner contact pairs.

12. The arrangement according to claim 11, wherein the contacts of a second outer contact pair of said contact pairs are arranged continuously parallel to one another, the contact being led in the contact region, parallel and in the opposite direction to the next adjacent contact of the inner contact pairs.

13. The arrangement according to claim 12, wherein the two outer contact pairs are arranged, in the connection region, on a magnetic field line of the inner contact pairs.

14. The arrangement of the contact pairs of a plug for a socket according to claim 10, wherein the contacts are led out in parallel over the contact region and the contacts of the one contact pair are then angled away twice in such a way that the contact pairs are located in a position virtually decoupled with respect to one another or are decoupled from one another by means of a sheet metal shield arranged between the contact pairs.

15. The arrangement according to claim 14, wherein the contacts of a first outer contact pair of said contact pairs are designed to be continuously parallel to one another, the contact being arranged, in the contact region, parallel and in the opposite direction to the next adjacent contact of the inner contact pairs.

16. The arrangement according to claim 15, wherein the contacts of a second outer contact pair of said contact pairs are arranged, in the contact region, parallel and in the opposite direction to one another, and are then extended in the form of a compensation loop, one contact being arranged to be equidirectional to another contact in the contact region and parallel in the region of the compensation loop.
