Definitions

  • the invention relates to an arrangement of contact pairs for compensation the crosstalk for an electrical connector
  • RJ-45 connector The most widespread electrical connector for symmetrical data cables is the RJ-45 connector, which depending on the technical requirements various embodiments is known.
  • Known RJ-45 connectors Category 5 points, for example, between all four Contact pairs have a crosstalk attenuation of> 40 dB at 100 MHz Transmission frequency. Due to the unfavorable contact assignment at Due to the design, RJ-45 occurs particularly with the plug between the both pairs 3, 6 and 4, 5 due to their nested arrangement an increased crosstalk, which can be used at high Restricted transmission frequencies. For reasons of compatibility with the However, the pin assignment cannot be changed with previous plugs. Because of this unfavorable structural arrangement are already for Approaching the near end> 40 dB at 100 MHz of category 5 special measures necessary. All known measures leave the plug untouched and bring about the improvement in the near crosstalk Compensation measures in the socket.
  • WO 98/04020, WO 97/44862 and US 5,310,363 are further Arrangements previously known, the further examples of crossed contact pairs demonstrate.
  • the invention is therefore based on the technical problem of an arrangement of contact pairs for an electrical connector with at least two nested contact pairs, especially for an RJ-45 connector, for higher transmission frequencies with sufficient To create crosstalk attenuation.
  • Another technical problem is that Creation of an electrical connector for high Transmission frequencies that are downward compatible to the known Cat 5 Connectors.
  • the crossing point placed directly behind the contact area, which is a minimal distance caused between the cross-talk zone and the compensation zone, so that Phase shifts due to running times are negligible.
  • the contacts are nested contact pairs run parallel in the contact area, the inner contacts being directed in opposite directions to the outer contacts are what an inductive decoupling of the non-current-carrying Partial areas of the internal contacts. Then there are the inner ones Contacts crossed and bent 180 ⁇ and again parallel to the formed first part. This causes immediately behind the Crossing point the generated crosstalk changes its sign and compensation of the crosstalk from the contact area takes place.
  • the contacts are used to generate the sufficient spring forces then nested contact pairs in a pointed one Angle bent and guided parallel to a connection area. to Decoupling and thus to limit the compensation range the inner contacts in front of the connection area again from the outer ones Bent contacts and again parallel to the outer contacts.
  • the crosstalk in the The connector was specifically chosen larger and then compensated again, whereby preferably the compensation zone divided into two sections, namely a compensation zone in the socket and a compensation zone on Connection area of the plug, for which purpose the internal contacts are also crossed become.
  • the inner contacts are in the compensation zone of the connector with a lower line impedance than trained in the crosstalk zone, so that between the contacts of the nested contact pairs are mostly capacitive Coupling takes place, which is the predominant part of the capacitive coupling in the Area transition plug / socket compensated, where the not current-carrying parts of the contacts of the socket and plug capacitive Act.
  • the outer non-nested contact pairs are parallel to each other performed, these in the contact area for decoupling to the contacts of nested contact pairs are guided in opposite directions. to The outer ones show better decoupling to the contacts of the socket Contacts following the contact area an indentation.
  • FIG. 1 a the pin assignment for an RJ-45 connector is shown.
  • the RJ-45 connector comprises four contact pairs 1, 2; 3, 6; 4, 5; 7, 8.
  • the associated contacts of a contact pair are not always included right next to each other, but the two middle contact pairs 3, 6 and 4, 5 are nested, which is a particularly strong one Crosstalk.
  • Fig. 3 is a perspective view of the middle, one inside the other nested contact pairs 3, 6 and 4, 5 shown.
  • To improve the Compensation gain in the socket is the distance between , Contact area 10, where the contacts of the plug contact those of the socket, and the compensation area is reduced.
  • FIG. 4 is a side view of FIG. 3 explained.
  • the contacts 3 and 6 of the spread pair are parallel and Completely identical, go from the contact area 10 in one first section 31, 61 after lings away, go in after a bend 32, 62 a straight part 33, 63 over and end on the right in a connection area 90, which can be a circuit board, for example.
  • the contacts 4 and 5 of the middle pair run in the contact area 41, 51 parallel to contacts 3 and 6 and go in the opposite direction right away and make a bend of 180 ⁇ 42, 52 where the cross both contacts, i.e. Seen from above, contact 4 takes the place of contact 5 and contact 5 that of contact 4. After crossing 11 the two contacts 4 and 5 run parallel and parallel to each other Contact sections 31 and 61. After another bend 44, 54 are the Contacts 4 and 5 on the same level as 3 and 6.
  • the compensation begins right behind the intersection 11 or bend 42, 52 by the parallelism of the contact areas 31, 61, 43, 53 and 33, 63, 45, 55.
  • leave the two contacts 4 and 5 with a bend 46, 56 decouples the compensation zone and ends in the connection area 90.
  • the contact sections 31, 32 and 41, 42, 43, 44 and 51, 52, 53, 54 and 61, 62 movable while the others lie firmly in the socket.
  • the contacts 203, 204, 205, 206 run completely parallel to each other. Only at the connection area 214 the contacts 204, 205 and 203, 206 are pulled apart, see above that in the connection area 214 due to the spacing of the contact pairs are largely decoupled. This can, as shown in Fig. 6, by a opposing bending of the contact pairs or by a simple one Angling of a contact pair can be achieved.
  • the mode of action of Contact arrangement of the improved connector is that so far restrict the usual large tolerances in crosstalk and that Set crosstalk to a lower tolerance value that is still Cat 5 fulfilled and matched to the compensation in the socket.
  • this crosstalk compensated by a second line section according to Fig.7b, for this purpose a line pair has been crossed, you get a limit curve for the Proximity crosstalk with optimal adjustment, which increases with 40 dB / dec.
  • This Limit curve is clearly explained by the mean distance d between the crosstalk and compensation zone, so that over the Compensation zone running signal a by twice the distance d has a longer term. This leads to an additional frequency dependent Phase shift that deviates from the intended 180 ⁇ to Crosstalk is canceled.
  • a closer look leads to the result that a gain with such compensation only for one Distance d ⁇ / 12 is given.
  • FIG. 9 shows the contact arrangement for the inner contacts 203, 204, 205, 206 shown.
  • the contacts 203, 204, 205, 206 have one low line impedance in compensation zone 213 compared to Crosstalk zone 211 on what, for example, by different Diameter or shape of the contacts is realized. This is what happens the two contact pairs in the compensation zone predominantly capacitive coupling instead.
  • the complete contact arrangement for the plug is shown in FIG. 10.
  • the outer contacts run in the Contact area 210 in opposite directions.
  • the current clearly flows into the outer one Contacts from top to bottom, inside from bottom to top. All Contacts are formed at their contact ends with radii around the To improve contact with the mating contacts of the socket.
  • the outer contacts 201, 202, 207, 208 point directly behind the contact area 210 indentations 215, which for better Decoupling with the contacts of the socket.
  • connection area 214 The continuation of the outer contacts 201, 202, 207, 208 from the contact area 210 to Connection area 214 is carried out parallel to the inner contacts 203, 206, 204, 205 in another plane such that a decoupling between the internal and external contacts takes place.
  • the cable connections in the Connection areas are made in pairs and through a matrix-like 2 x 2 Arrangement spatially separated from each other, so that cable influences due undefined twist are low.
  • 11-13 is the contact arrangement for a socket with a Printed circuit board 91 and the assembled insulation displacement contacts 92 in different perspective views.
  • the contacts are in not installed condition, i.e. without socket body.
  • Will the Contact set installed in a socket body, not shown, are eight contacts in parallel and under the necessary bias.
  • the eyes on the circuit board for contacts 1, 2 and 4, 5 and 7, 8 are offset to here to maintain the necessary minimum clearance for the creepage distances.
