Definitions

  • the present invention relates to connected connection devices pairs of multi-pair high signal cable frequencies and provided with crosstalk compensation means between these pairs to connect to other pairs.
  • connection devices include contact elements which are arranged side by side in the same row and to which the wires isolated from cable pairs.
  • the pairs of insulated wires are made free by stripping the part end of the cable and are removed.
  • the proximity and parallelism of different pairs of wires isolated on this stripped and stripped end part of the cable and the proximity of the contact elements in their row give problems of crosstalk between adjacent pairs, which limit the permissible transmission frequencies on the pairs.
  • Document DE-C1-196 49 668 discloses such a male connector mounted on a cable with four individually screened pairs.
  • This connector has eight contact elements adjacent to each other. to others in a row and a support for flat wiring of pairs and wires isolated from these pairs.
  • This wiring support has a rear part of holding the pairs, a front part for guiding or connecting the wires isolated and an intermediate part called crossover.
  • This intermediate part area is divided into four parallel channels by separators provided thereon. Extreme pairs of insulated wires received on it are each guided in one of the two extreme channels and are kept screened practically up to the front part of connection. The two sons isolated and freed from their screen from each of them are connected to the two contact elements located at one end of the row. On the other hand, the two middle pairs received on the intermediate part are immediately released from their individual screen. Their isolated sons are crossed, in being guided in the two median channels and having in one of these two middle channels two isolated wires belonging to one of the two median pairs, thereby creating coupling compensations along these middle channels. They end up in the connection part in a desired order, which is changed from their original order, where they are connected to the four middle contact elements in the row.
  • This connector is relatively complex. It takes advantage of the cable to screened pairs on which it is mounted, but such a cable is very expensive compared to a cable with unshielded pairs. Its mounting on such a cable is made difficult and particularly long.
  • This female connector is internally fitted with conductive inserts flexible and arched, which are arranged in a row, are accessible to through a front opening for plugging in a male connector complementary and are retained in a rear part of this connector female. It also has a row of flat insulation displacement contacts, the first insulation displacement ends of which are connected to the inserts conductors in the rear part of the female connector and the second insulation displacement ends protrude externally on this part back.
  • the rear coupling compensation module is fitted directly on the cable and is snapped onto the rear of the connector female. It is made up of two similar parts and assembled one to the other, which successively define a rear entry between them cable retention, a rear row of separation channels and holding flat wires isolated from different pairs of cable, a crossover cavity of these insulated wires and a front row of guide and connection channels wires with insulation displacement contacts. These connecting channels are split right through their length for the insertion of insulation displacement contacts in these when the rear module is snapped onto the female connector before.
  • the rear row channels, and therefore the insulated wires present in these upstream of the crossing cavity are of predetermined length, to achieve coupling compensation between the parallel paths of transmission defined downstream of the crossings, by the insulation displacement contacts and the conductive inserts of the socket connected to each other and to the cable pairs.
  • This female connection set uses conductive inserts significantly reduced length in its front female connector, which correspondingly reduces the couplings to be compensated.
  • it uses contacts insulation displacement insulation for the connection of the pairs of insulated wires to the inserts conductors.
  • These insulation displacement contacts which are parallel and face to face in their row, considerably increase the coupling to compensate in said rear row channels and limit the accuracy of the balance sought by the compensation to be achieved. They also create areas with high characteristic impedance break of the pairs, which is added to the break characteristic impedance also provided by the conductive inserts and is due to the spacing of the isolated wires of the pairs along the module of compensation and at the predetermined length but relatively large necessary rear row channels.
  • connection of these insulation displacement contacts to the insulated wires in the connection channels of the coupling compensation module which is made parallel to the wires isolated, requires a very large insertion force, makes it not easy to click of this rear module on the front female connector and may cause a slip of the insulated wires in the connection channels and / or a incorrect connection of these wires to the insulation displacement contacts.
  • This mode of connection of the insulation displacement contacts to the insulated wires prohibits that these wires isolated have a multi-strand core.
  • the object of the present invention is to overcome the drawbacks of the aforementioned known connection devices, to improve the compensation of coupling performed and reduce the harmful effects.
  • a device for connecting a multi-pair cable, to reduced crosstalk rate comprising a stripped end portion of said cable, an insulating body, a row of first contacts mounted in said body, and, along said stripped end portion of said cable, means rear support provided with a row of channels, parallel to each other and of defined length, of keeping the wires isolated from said pairs, a means front support for guiding said wires at the pitch of said first contacts and in a defined order different from that of said wires in said channels, for the connection of said wires and of said first contacts to each other, and a so-called intermediate crossing part of the wires isolated from said pairs, characterized in that said channels are open laterally in each others along their length and define a closed passage peripherally of clamping of all of said insulated wires, joined in sheet form against each other, and clamping towards the end of the sheath of said cable and in that said front support means includes a connection path transverse of said insulated wires to said first contacts.
  • connection devices illustrated in these drawings are all intended to ensure the connection of multipair cables, which is carried out as appropriate using a male connector according to the invention and a conventional complementary female connector both of the type RJ45, or in a connection strip equipped according to the invention, or even using a patch connector equipped according to the invention and a conventional connection strip receiving this patch connector.
  • These devices according to the present invention are provided to allow high speed transmissions, ranging from 100 M bits / sec. at several G bits / sec., improving the crosstalk performance between pairs and thus making it possible to meet the requirements of category 5 + and 6 transmission standards.
  • the male connector is of the RJ45 type designed for a cable C comprising four unshielded pairs, the wires of which isolated from different pairs are organized in a terminal row in this connector.
  • These insulated wires were numbered from 1 to 8 along the row terminal. They are in a pre-established order along this terminal row, to respect the order as provided in the usual way of the points of connection to the corresponding pairs in a female RJ45 connector so as to limit in it the couplings between median pairs.
  • the pairs of cable C are those formed for wires 1 and 2, 3 and 6, 4 and 5, 7 and 8.
  • This connector integrates the terminal part of the stripped cable and comprises an insulating body 10, an insulating wiring support 11, a stud so-called coupling compensation insulator 12 and a set of eight contacts 13.
  • the coupling compensation pad 12 mounts directly on the assembly insulated wires from the cable pairs and removably attaches to the wiring support 11.
  • the latter and the aforementioned stud which it then carries are mounted in the insulating body 10, which covers them completely and extends as far as cable C.
  • This insulating body is of known type. We see a terminal row front of slots 14 through its front face and one of its main faces, which receive the contacts 13 at the desired step between them. We also see a paw 15 for guidance and elastic locking in the female RJ45 connector, this tab being integral with the front part of the other main face and lying moreover freely opposite it. The rear end 16 of the body is open.
  • the contacts 13 are flat and of known type in the connectors RJ45 males. Their first ends 17 received in the insulating body are perforating. Their second opposite ends 18 constitute the terminals of connection of this male connector to those of the female connector.
  • the wiring support 11 has a front end portion 21 of guiding insulated wires for their connection to the contacts, part rear terminal 22 between them insulated wires for the coupling compensation to be achieved and an intermediate part 23 of crossing of the insulated wires between the two parts 21 and 22.
  • the front part 21 has a row of guide channels 24, parallel and defined in pitch contacts 13 in the slots 14. These channels are split on one side only, for the insertion of the perforating ends of the contacts into them. They are of reduced and defined length and allow the connection of wires and contacts along a transverse path.
  • the rear part 22 is assigned to the detachable holding of the stud on the support.
  • the coupling compensation pad 12 has a row of parallel channels 27, which are open laterally along one in the others and thus define a single peripherally closed passage of clamping of all of the insulated wires, joined together in ply against others. It also ensures the maintenance of this layer of son at a distance as small as possible from the end of the cable sheath C.
  • These channels 27 and therefore the stud are of very short predetermined length.
  • flexible lateral tabs 28, with internal tooth 29, ensure the retention of the stud by hooking into the shoulder notches of the cable support.
  • This stud 12 is preferably made in one piece. He can variant be in two parts which can be superimposed and assembled to each other or be formed half on the rear part 22 and the other half by a cover retained on it.
  • the intermediate part 23 of the support 11 is like the stud 12 of very short length, which is preferably that just necessary to realize crossings and then ensure that they remain unchanged in position.
  • the crosses of wires 1 to 8 thereon are preferably made using all pairs and advantageously avoiding crossing more than two son over each other. They are made between wires 1 and 2, 4 and 5, 7 and 8 as shown in Figure 2. Alternatively, they can be made between wires 3 and 6 with the wires 3, 6 and 4 and the wires 3, 6 and 5 superimposed. The order of passage of the wires in the stud is then that of the wires 2, 1, 3, 5, 4, 6, 8, and 7. In the variant indicated, this order is that of the wires 1, 2, 6, 4, 5, 3, 7 and 8.
  • this connector on the stripped end portion of the cable is very fast and very easy. It is done by first mounting the stud 12 on all of the insulated wires put in the order of passage indicated above. The stud is then fully slid towards the sheathed cable to obtain a very short distance between the stud and the end of the cable sheath. Insulated wires are then crossed as also indicated above and inserted in the guide channels 24, the stud being already fixed or being so after on the support of wiring. Wires are taut, cable support pushed against cable sheathed and the excess lengths of the cut wires. The cable support thus fully equipped is fully mounted in the insulating body, which positions the stud in the insulating body. Contacts are inserted in slots 14 and into the channels 24, being in this way connected to the wires held in place in them. The insulating body is therefore directly blocked on the cable.
  • This insulating body is provided long enough to come over the sheathed cable. It can of course be associated with a rear cap, which is previously threaded on the cable or made in two assemblable parts and is then received and held on the rear end of the insulating body, or a molding or a rear finishing sleeve made between the insulating body and the sheathed cable.
  • the insulating body can be coated with a shield outside.
  • the tightening in length of the stud 12 of the wires contiguous, which belong to different pairs, allows a very rigorous, reliable and reproducible compensation for couplings between pairs after crossing the wires. It allows with a very long stud reduced, by more than 5 mm, obtaining the fairest compensation sought couplings between pairs in the male connector.
  • the length reduced of the intermediate part 23 allows the invariant maintenance in position different crossings made, for this compensation obtained without special care when mounting the connector on the cable and for its conservation over time.
  • the length of this intermediate part 23 can be less than 5 mm.
  • the cable support thus has a length itself reduced to no more than 15 mm, to be easily installed in a standard RJ45 male connector body.
  • the standard connector thus produced enables the requirements of transmission standards to be met without problems in category 6 using a female connector complementary to reduced compensation of couplings therein.
  • the four median channels of the stud are provided longer than the two lateral channels of this stud and the four median guide channels of the front part of the cable support on the intermediate part are shorter than the lateral ones.
  • the four median channels of the stud are salient and the four middle channels of the front part of the wiring support are set back, by relative to the ends of their lateral channels.
  • Other provisions could be planned. This allows to offset the crossing of the two wires medians compared to the crossings of the two extreme wires while now the invariant crossovers and get stronger compensation of coupling between some of the pairs, preferably between the pairs medians, ie where the coupling is precisely the strongest.
  • connection strip classic to improve its transmission performance, as described opposite Figures 3 and 4.
  • This strip has an insulating body 30 and two rows of insulation displacement contacts 32, mounted in the body, being from one row to the other two by two opposite and connected to the rear of the body and being kept separate from each other along these rows by partitions insulating 33. It has on each of its faces a front terminal series flat lugs 34 which delimit slots 35 between them located at the level of the insulation displacement slots 36 of the contacts.
  • each row has eight contacts.
  • An incoming cable marked C with four pairs of insulated wires marked 1 to 8 is connected to the contacts of one of the rows, the pairs being successive the along this row.
  • Other pairs called another's subscriber lines or other cables not shown are connected directly without compensation of coupling to the successive pairs of contacts of the other row and are thus connected to the pairs of cable C in the strip.
  • the strip can of course include a greater number of contacts per row and be served by one cable or more cables large overall capacity than the aforementioned cable C. It may also include already known way of the screens between the pairs of contacts of one and the other of the two rows to reduce crosstalk between successive pairs connected to subscriber lines.
  • the stud 40 is advantageously assigned to 4 pairs of insulated wires, is analogous to stud 12 in Figures 1 and 2 and is centered with respect to the 4 pairs contacts to which these 4 pairs of wires are connected. It ensures the tightening of the set of insulated wires joined in ply against each other, at a reduced distance from the end of the cable sheath C. Its possible differences with the stud 12 are its length which can be slightly more large and / or its mode of retention on the insulating body. It is therefore not described in more detail.
  • the part 31 of the insulating body 32 defines, as the wiring support Figures 1 and 2, a front portion 41, which is assigned to the guide wires 1 to 8 parallel to each other, at the contact pitch and transversely to these contacts, a non-terminal rear part 42 assigned to the retention of the stud 40 on it, and an intermediate portion 43 for crossing the wires. These parts have reduced lengths, which are predetermined between them.
  • the front part 41 guide is defined by the bottom of the different slots 35, the bottoms of these slots constituting paths for the insulated wires which are bent at this level and are connected transversely to the contacts 32.
  • Two passages 46 through the rear part 42 are provided opposite to receive the side tabs 48 for fixing the stud 40 and retaining it positioned relative to the front part 41, allowing the crossings on the intermediate part 43.
  • the crossings of the wires on this intermediate part are made between the two wires of the same pair, treating the pairs according to their rank and length between the stud and the contacts to which they are connected.
  • An even number of crosses (0 or 2 crosses) is made on pairs of even rank considered from one end of the layer of wires emerging from the pad 40, while an odd number of crosses (1 or 3 crosses) are made on odd-numbered pairs. So as shown for example, wires 1 and 2 are crossed once one on the other, wires 3 and 4 are uncrossed, wires 5 and 6 are crossed once and wires 7 and 8 are not crossed.
  • the end wires 1 and 2 can be crossed three times one over the other and the extreme wires 7 and 2 twice, to hold account for the fact that these wires are left longer than the wires of the pairs to ensure reinforced twist in the wires of these extreme pairs and thus obtain a better tightening of the crossings for their maintenance invariant and better control of coupling compensations.
  • the connector illustrated in Figure 5 allows connection removable from a multi-pair cable also noted C to a conventional strip of connection, this generally having a higher number of contacts per row.
  • This cable C thus equipped is then a connection cord and brewing. It corresponds to a given variant compared to the connection fixes pairs of cable C in the strip of the type of that of FIGS. 3 and 4. It is inserted between the two rows of contacts of the strip and connects the wires isolated from the pairs of cable C at as many successive contacts of one of the two rows of contacts of the strip and thus to other pairs of wires connected fixedly to the other row of contacts on the strip.
  • this so-called patch connector is equipped with means wiring and coupling compensation, while the strip is not and remains unchanged and used as in the past.
  • This patch connector has a wiring and coupling compensation 50 and a cover 60 which can be assembled on the support, thereby defining the body of the connector.
  • the support 50 comprises a terminal front part 51, a part non-terminal rear 52 and an intermediate portion 53, which are analogous to the corresponding parts 41, 42, and 43 on the part 31 of the insulating body 30 of the strip of Figures 3 and 4 and the corresponding parts on the support 10 of FIG. 1.
  • the front part 51 is provided with a row of channels 54 of guiding the insulated wires of the pairs of the cable C, in parallel and at the pitch of contacts to which they are to be connected.
  • the intermediate part 53 is affected at the crossings of the isolated wires made on it as indicated on the part intermediate 43 of the strip of Figures 3 and 4.
  • a shoulder 55 is provided between the intermediate and front parts.
  • the rear part 52 retains a stud 62 coupling compensation.
  • This rear part 52 is extended by a rear terminal return at bracket 57, which is crossed by the sheathed cable and receives just before the stud the insulated wires released from the underside of the sheathed cable sheath.
  • Lateral notches such as 56 are provided on the support of wiring 50 for retention of cover 60.
  • the pad 62 is similar to the pad 40 of the strip of Figures 3 and 4, itself similar to the pin 12 of the connector of Figures 1 and 2. It is therefore no longer described.
  • the lateral lugs for hooking this stud 62 on the support 50 can be omitted, keeping the stud in place can be ensured by the cover 60 in place on the support.
  • the cover 60 fits on the support 50 which it covers and closes in long. Legs 66 received in the lateral notches 56 ensure its hold in place. It carries a row of contacts 67 retained in one part front of this cover, being in line with the channels 54. These contacts 67 have one end with piercing points 68, which protrudes internally on the cover and located to the right of the insulated wires in the channels 54 to be there transversely connected. They have another end 69, which is slightly protruding externally on the cover for their connection to one of the rows of contacts of the strip receiving this connector. Of course these contacts may have a insulation displacement end instead of the tip perforating, the channels 54 then being split transversely to allow a connection of the insulation displacement contacts transversely to the wires in square.
  • This connector improves the performance of the strip in which it is plugged in, reducing the couplings between the pairs of cable C connected to other pairs in this strip and thus obtaining the performance of the strips fitted according to Figures 3 and 4.
  • the patch connector according to the given embodiment variant in FIGS. 6 to 8 is a connector of global type also known which has been equipped according to the present invention.
  • It comprises an insulating body 70, in which a row is mounted eight contacts 75.
  • the front of this connector is plugged into a strip classic connection by ensuring the elastic connection of its contacts 75 to eight successive contacts from one of the two rows of contacts on the strip.
  • Keying means are provided in the front face of the insulating body for this plug-in.
  • the contacts 75 of this connector have their rear end insulation displacement insulation which is connected to one of the insulated wires 1 to 8 of the pairs of a multipair cable C, using on these wires the arrangements according to the invention of compensation of couplings between pairs.

  • the crossings of the insulated wires in the intermediate part are similar to the crossings made on the strip of Figure 3.
  • This patch connector also includes protection assembly 77, also ensuring the holding in position of the pad 72 relatively to the insulating body and therefore to the contacts therein and relatively i to the sheathed cable C.
  • This protection 77 is advantageously an overmolding on the insulating body and even on the sheathed cable, in which the stud is embedded and the crossings of the wires thus made invariant in position. It forms a transition 78 between the insulating body and the sheathed cable, which has grooves peripherals 79 giving it good flexibility.
