  • This Connector has an undesirable in the direction of insertion great length and proves to be sensitive against screen surfaces (shields), as they are on the Are attached to the outside of the sockets to be inserted.
  • EP 0 889 558 describes a special conductor arrangement described a connector which for the Capacitive and inductive coupling compensation between the individual conductors is particularly advantageous. However, this connector is not suitable for one Broadband transmission of category 6.
  • Analog connectors are also from US 5,911,602 and US 5,938,479 known. The ones in these documents Disclosed connectors can meet the standards for Also do not meet Category 6 connectors and do not have a very compact design.
  • RJ45 plug connections are included a definition for the design of the mating face, whereas for the course of the contacts from the mating area there are no regulations. Therefore, RJ45 plug connections are with a variety of different arranged conductor tracks known. Especially with RJ-45 connectors Category 5 is known for example from the cited document, the course arrange the conductor tracks in such a way that a targeted Crosstalk compensation occurs. All of these for one Signal bandwidth of 100 MHz plug connections has in common that it consists of the following, physical Reasons for higher bandwidths hardly or not at all are suitable. The mechanical dimensions of this Systems, especially the distance between the connector and Compensation, as well as the expansion of the compensations, are so big that at high frequencies one additional phase shift between the interference signal and the compensation signal occurs, which affects the effectiveness the existing compensation for these frequencies limits.
  • the connector part according to the invention has a Compensation of crosstalk on, the compensation is extremely compact and both capacitive and also contains inductive coupling paths.
  • the conductor tracks of the connector part have a minimal spatial Extension to.
  • certain conductor tracks are crossed and for mutual compensation in two parallel planes, whereby between an electrical insulator to these two parallel planes or a dielectric is arranged around a to achieve capacitive coupling path.
  • An advantage of the connector comprising the inventive Connector part is the fact that this even with signals with a bandwidth of 200 MHz only one Crosstalk of at most -48 dB.
  • Another advantage is the fact that the connector part is very compact and small. This enables existing sockets by containing a socket the broadband connector part according to the invention exchange, thereby the bandwidth of existing Increase network. Those permanently installed in a building mutually twisted electrical conductors must be used not be replaced, which is an inexpensive Bandwidth expansion allowed.

  • Fig. 2 shows a connector part 80 from the viewing direction B.
  • Eight tracks 1-8 each have one at one end Contact spring 11-18 on and at the other end one each Output contact 71-78, which is designed as an insulation displacement terminal is.
  • the contact springs 11-18 run along one Contact spring section 19 in a common area and mutually parallel.
  • the contact springs 11-18 are in their V-shaped longitudinal direction and each have a contact point lla-18a, which at inserted plug 83 on the respective contact points of the plug 83 rest.
  • the contact springs 11-18 start at one, facing away from the output contacts 71-78 End, and run to the output contacts 71-78.

  • crossover section 39 within which the conductor pairs 1,2; 4.5 and 7,8 cross each other.
  • the partial lengths 41-48 arranged in section 49 of the conductor tracks 1-8 are partially in the longitudinal direction of the insulator 40 widely configured to be a to effect correspondingly greater capacity. Also are individual partial lengths 41-48 with respect to the insulator 40 arranged opposite, thereby also a increased capacity between the respective conductor tracks 1-8 to effect.
  • the conductor tracks 1-8 open after the Section 49 in a deflection section 59, inside which deflects the conductor tracks 1-8 by about 90 degrees are.
  • a crossover section 69 arranged, within which the conductors 1-8, as in 4b shown in a developed top view, cross.
  • the crossover section 69 is subsequent an insulation displacement region 79 with insulation displacement contacts 71-78 arranged.
  • the course of the conductor tracks 1-8 can also be configured in this way be at least some of the traces 1-8 cross each other in the deflection section 29, 59, so that the deflection section 29, 59 also the Crossover section 39, 69 corresponds.

All contact springs 11-18 run in the same plane, whereby only the contact spring 11 with contact point 11a is designated. The course changes at the deflection point 29 of the conductor tracks 1-8 with respect to the alignment of the Contact springs 11-18 about 90 degrees. The conductor tracks 1-8 then run in two parallel planes, with the one level the conductor track sections 41, 42 and in the another level, the conductor track section 43 is shown. The isolator 40 is between these two levels arranged.
