Abstract

An arrangement of contact pairs (1, 2; 3, 6; 4, 5; 7, 8; 201, 202; 203, 206; 204, 205; 207, 208) for an electric patch plug for compensating the near-end crosstalk with contact pairs interlaced with one another, especially for an RJ-45 patch plug, in which the contacts (4, 5) are crossed for compensation. The crossing point (11) is placed in the elastically mounted part of the contacts (1, 2; 3, 6; 4, 5; 7, 8) of the socket.

a second contact pair, each second contact pair contact having a second contact pair terminal area, each second contact pair contact having a second contact pair contact area, each second contact pair contact being fixed to said contact support and defining a fixedly mounted second contact pair contact partial area adjacent to said second contact pair terminal area with each second contact pair contact having a portion mounted in a fixed manner defining a fixedly mounted contact partial area and each second contact pair contact having a second contact pair elastically mounted partial area with the second contact pair contact mounted elastically for movement in the socket body, said second contact pair being disposed between respective contacts of said first contact pair, said contacts of said second contact pair crossing each other to define a crossing point and to position one of said contacts of said second contact pair closer to one of said contacts of said first contact pair at one side of said crossing point and closer to the other of said contacts of said first contact pair at another side of said crossing point and to position the other of said contacts of said second contact pair closer to said other of said contacts of said first contact pair at said one side of said crossing point and closer to said one of said contacts of said first contact pair at said another side of said crossing point, said crossing point being located at the elastically mounted partial area of said contacts of said contacts of said second contact pair.

2. The arrangement in accordance with claim 1, wherein a region of said crossing point is directly adjacent to said contact area.

3. The arrangement in accordance with claim 2, wherein:

said contacts of said second contact pair extend in parallel in said contact area which is in a first partial area;

contacts of said first contact pair extend in parallel to said contacts of said first contact pair in said contact area and extend in a direction which is opposite a direction of extent of said contacts of said second contact pair;

said contacts of said second contact pair change direction by 180°

in a second partial area;

said crossing point of said contacts of said second contact pair is in said second partial area;

said contacts of said second contact pair extend from said second partial area, in parallel to said first partial area, in another partial area adjoining said second partial area.

4. The arrangement in accordance with claim 3, wherein:

said contacts of said second contact pair have a further contact adjoining area, adjoining said first partial area, said contacts of said second contact pair being bent in said adjoining area and extending in parallel in a parallel run partial area; and

said contacts of said second contact pair have another crossing contact adjoining area, adjoining said another partial area, said crossing contacts being bent in said crossing contact adjoining area and extending in parallel in said parallel run partial area.

5. The arrangement in accordance with claim 4, wherein said crossing contacts are bent off from said parallel run partial area toward said terminal area and are led in parallel in a decoupled position relative to said further contacts.

6. The arrangement in accordance with claim 3, further comprising further contact pairs extending in said contact area in a same direction and in parallel to said contacts of said second contact pair and being bent in or adjacent to said second partial area and extending parallel and being bent again and extending parallel to said parallel run area to said terminal area.

7. A socket for an electric patch plug, comprising a socket body and a set of contacts, wherein said contacts are designed as an arrangement including:

a socket body with a contact support;

at least two contact pairs interlaced with one another, wherein the contacts have a terminal area and a contact area and a fixedly mounted partial area mounted in a fixed manner to said contact support and with said fixedly mounted partial area positioned adjacent to said terminal area and having an elastically mounted partial area mounted elastically in said socket body adjacent to said contact area;

one of said contact pairs being two crossing contacts with a crossing point of said two crossing contacts to provide said two crossing contacts in a crossed position, said crossing point being located in the elastically mounted partial area of the contacts.

8. The arrangement in accordance with claim 7, wherein said crossing point directly joins said contact area.

9. The arrangement in accordance with claim 8, wherein:

said contact area of said crossing contacts extend in parallel in said contact area which is in a first partial area;

the other of said contact pairs interlaced with one another extend in parallel to said crossing contacts in said contact area and in an opposite direction to said two crossing contacts;

said two crossing contacts change direction by 180°

in a second partial area;

said crossing point is in said second partial area;

said two crossing contacts extend from said second partial area, in parallel to said first partial area, in another partial area adjoining said second partial area.

10. The arrangement in accordance with claim 9, further comprising:

a further contact adjoining area, adjoining said first partial area, said further contacts being bent in said adjoining area and extending in parallel in a parallel run partial area; and

another crossing contact adjoining area, adjoining said another partial area, said crossing contacts being bent in said crossing contact adjoining area and extending in parallel in said parallel run partial area.

11. The arrangement in accordance with claim 10, wherein said crossing contacts are bent off from said parallel run partial area toward said terminal area and are led in parallel in a decoupled position relative to said further contacts.

12. The arrangement in accordance with claim 9, further comprising further contact pairs extending in said contact area in a same direction and in parallel to said crossing contacts and being bent in or adjacent to said second partial area and extending parallel and being bent again and extending parallel to said parallel run area to said terminal area.

13. RJ-45 type patch plug, comprising

a plug arrangement of plug contact pairs including at least two plug contact pairs interlaced with one another and arranged in parallel to one another and uncrossed in a contact area, contacts of said plug contact pairs extending from a terminal area to form a defined side-to-side crosstalk zone and a decoupled contact pair zone with contacts of each pair extending in a decoupled position in relation to one another from adjacent to said crosstalk zone to said terminal area;

and

a socket with a socket body with a contact support and with arrangement of socket contact pairs with at least two socket contact pairs interlaced with one another, wherein each socket contact of said socket arrangement of socket contact pairs is arranged partially in a fixedly mounted partial area and is mounted in a fixed manner adjacent to a terminal area and each contact has an elastically mounted part in an elastically mounted partial area with socket contacts mounted elastically in said socket body adjacent to a contact area, the socket arrangement including a crossing point of two crossing contacts of said contact pairs interlaced with one another to provide said two crossing contacts in a crossed position, said crossing point being located in the elastically mounted partial area of the contacts.

14. The RJ-45 type patch plug in accordance with claim 13, wherein one of a contact length and/or distances between said contacts in the area of said side-to-side crosstalk zone are selected to so as to provide that a greater side-to-side crosstalk becomes established in said crosstalk zone compared with a category 5 plug.

15. The arrangement in accordance with claim 13, wherein two of said plug contacts are crossed between said side-to-side crosstalk zone and said terminal area and form a compensation area.
