Abstract

The plug connector part has contacts connected to the separated ends of the twisted pair cables for reversible connection to corresponding contacts in a complementary part in the plug connector. The separated cables of the twisted wire pairs are fed directly in the cable outlet region, in a defined sequence, in parallel. This is in two planes and at a defined distance apart into a non-conducting contact housing (11) that can be installed in the contact plug. Here the cables are connected to the contacts (1' to 8') via insulation removal contact elements (9).

Description

Die vorliegende Erfindung betrifft ein Steckverbindungsteil, insbesondere Kontaktestecker einer Steckverbindung für hochfrequente Datenübertragung über mehrere verdrillte elektrische Leiterpaare eines Kabels, welche Leiter am Kabelende durch Auflösung der Verdrillung vereinzelt und über Drahtanschlussmittel an Kontakten angeschlossen sind zur lösbaren Verbindung mit korrespondierenden Kontakten des Gegenstückes der Steckerverbindung.The present invention relates to a connector part, in particular contact plug a connector for high-frequency data transmission via several twisted pairs of electrical conductors of a cable, which conductors at the end of the cable isolated by dissolving the twist and via wire connection means are connected to contacts for detachable connection with corresponding Contacts of the counterpart of the connector.

Im Bereich der Telekommunikation resp. der hochfrequenten Datenübertragung über elektrische Leiter sind modulare Steckverbindungssysteme, wie RJ 45 (8-polig) oder RJ 11 (6-polig), mit vorgegebener Kontaktstellenbelegung üblich, beispielsweise mit einer Belegung der Anschlüsse 4 und 5 oder 1 und 2 für die Empfängerschleife und der Anschlüsse 3 und 6 für die Senderschleife. In the field of telecommunications, respectively. high-frequency data transmission Modular connector systems such as RJ 45 (8-pin) or RJ 11 (6-pin), with specified contact point assignment usual, for example with an assignment of connections 4 and 5 or 1 and 2 for the receiver loop and connections 3 and 6 for the transmitter loop.

Dabei ist es beispielsweise bei RJ 45 - Steckverbindungssysteme Vorschrift, die Anschlusskontakte für das Leiterpaar 3/6 an der Schnittstelle zu trennen und den Anschlusskontakt von Leiter 3 zwischen den Anschlusskontakten der Paare 1/2 und 4/5 sowie den Anschlusskontakt von Leiter 6 zwischen den Anschlusskontakten 4/5 und 7/8 anzuordnen.In the case of RJ 45 connector systems, for example, it is a requirement that Disconnect connection contacts for the conductor pair 3/6 at the interface and the Connection contact of conductor 3 between the connection contacts of pairs 1/2 and 4/5 and the connection contact of conductor 6 between the connection contacts Arrange 4/5 and 7/8.

Die Qualität solcher Steckverbindungssysteme hängt dabei u.a. und im besonderen von der sogenannten Nebensprech- bzw. Übersprechdämpfung ab, da zwischen den Leitern eine Kopplung durch Übersprechen erfolgt. So wird von der störenden auf die gestörte Leitung eine bestimmte Leistung übergekoppelt, wobei die Masszahl hierfür die Übersprechdämpfung in dB ist. Je geringer dabei die Übersprechdämpfung, umso größer die eingekoppelte Störung. Durch eine gezielte Übersprechkompensation kann diese Störleistung verringert bzw. kompensiert werden, wobei eine gezielte Überkopplung einer zusätzlichen gleichgrossen, jedoch gegenphasigen Leistung angestrebt wird.The quality of such connector systems depends, among other things. and in particular from the so-called crosstalk or crosstalk attenuation, since between the conductors are coupled by crosstalk. So from the disturbing coupled to the disturbed line a certain power, whereby the measure for this is the crosstalk attenuation in dB. The lower the Crosstalk attenuation, the greater the coupled interference. Through a targeted Crosstalk compensation can reduce or compensate for this interference power with a targeted coupling of an additional equal-sized, however, phase-to-phase performance is sought.

Es sind deshalb verschiedene Massnahmen bekannt geworden, um die Übersprechdämpfung bei solchen Steckverbindungssystemen mit bereits festgelegter Kontaktbelegung an den Anschlusselementen geeignet zu verbessern. Dies war aber bisher nur über die Anschlussbuchsen der Steckverbindungssysteme möglich, wobei versucht wurde, die schlechten HF-Eigenschaften der Stecker solcher Steckverbindungssysteme zu kompensieren, was nur bedingt und mit grossem Aufwand erreicht werden konnte. Zudem können die bekannten Stecker mit vor gegebener Auskreuzung der Leiter nur aufwendig von Hand beschattet werden, wobei die verwendeten flächigen Piercing-Kontakte neben einer kritischen Kontaktierung der Leiter zudem durch Kondensatorwirkung die HF-Eigenschaften weiter verschlechtern.Various measures have therefore become known to reduce crosstalk in such connector systems with already defined Suitable to improve contact assignment on the connection elements. This was but so far only possible via the connection sockets of the connector systems, an attempt was made to identify the poor RF properties of the plugs To compensate for connector systems, which only to a limited extent and with great Effort could be achieved. In addition, the known plugs can be used given crossing of the ladder can only be shaded by hand, where the flat piercing contacts used in addition to a critical contact the conductor also has the HF properties due to the capacitor effect continue to deteriorate.

Aufgabe der vorliegenden Erfindung ist deshalb die Schaffung eines Steckverbindungsteils, insbesondere Hochfrequenzsteckers von Steckverbindungssystemen der vorgenannten Art, bei dem selbst sowohl elektrische (kapazitive) als auch magnetische (induktive) Übersprechkopplungen soweit als möglich reduziert werden, um damit eine Nebensprechunterdrückung über den 200 MHz-Bereich hinaus zu ermöglichen, respektive um auf spezielle Kompensations-Massnahmen in der Buchse möglichst verzichten zu können. Zudem ist die Anordnung so zu treffen, dass die einzelnen Leiter leicht und auf maschinellem Wege mit den Anschlusskontakten verbindbar sind und sich alles für den Einbau in die genormte Baugrösse eines üblichen Hochfrequenzsteckers eignet.The object of the present invention is therefore to create a plug connection part, especially high-frequency connector of connector systems of the aforementioned type, in which both electrical (capacitive) and magnetic (inductive) crosstalk couplings reduced as much as possible to achieve crosstalk suppression over the 200 MHz range to enable, or in order to special compensation measures to be able to do without in the socket. In addition, the arrangement so that the individual conductors are light and machine-based Paths can be connected to the connection contacts and everything for installation in the standardized size of a conventional high-frequency connector.

Dies wird erfindungsgemäss zunächst dadurch erreicht, dass die vereinzelten Leiter der Leiterpaare unmittelbar im Kabelaustrittsbereich in vorgegebener Reihenfolge parallel und in zwei Ebenen sowie mit vorgegebenem Abstand zueinander in einem in den Kontaktstecker einbaubaren Kontaktgehäuse aus nichtleitendem Material geführt und dort je vorzugsweise über eine Schneidklemme an einem Schneidklemm-(IDC)-Kontaktelement mit den betreffenden Kontakten aufgeschaltet sind. According to the invention, this is first achieved in that the individual Conductor of the pairs of conductors directly in the cable exit area in a predetermined order parallel and in two planes as well as at a predetermined distance from each other in a contact housing made of non-conductive that can be built into the contact plug Material guided and there preferably via an insulation piercing clamp an insulation displacement (IDC) contact element connected to the relevant contacts are.

Hierbei ist es von Vorteil, wenn die vereinzelten Leiter in das Kontaktgehäuse einlegbar sind und sich dort isoliert zwischen Rippen des Kontaktgehäuses erstrecken und ferner, wenn die Kontakte der Schneidklemm-Kontaktelemente eine Reihe bilden und sich am freien Ende von an den Schneidklemmen abragenden und entsprechend abgebogenen Kontaktarmen befinden, wobei zwischen den Kontakten und deren Schneidklemmen ein in Leitererstreckung kürzestmöglicher Abstand besteht. Vorteilhaft hierfür ist weiter, wenn die Schneidklemm-Kontaktelemente im wesentlichen starr ausgebildet sind.It is advantageous if the isolated conductors in the contact housing can be inserted and extend isolated between ribs of the contact housing and further if the contacts of the insulation displacement contact elements are one Form a row and protrude at the free end of those protruding from the insulation displacement clamps and are accordingly bent contact arms, being between the Contacts and their insulation displacement terminals as short as possible in the conductor extension Distance exists. This is also advantageous if the insulation displacement contact elements are essentially rigid.

Für das Aufschalten randnaher Leiter können weiter die betreffenden Schneidklemm-Kontakelemente seitlich nach aussen gebogen sein. Ferner können sich vorgegebene Kontaktarme für eine wechselnde Anordnung von Leiterpaaren bezüglich der Kontakte der Schneidklemm-Kontaktelemente entsprechend übergreifen.For the connection of conductors close to the edge, the relevant ones can also be used Insulation displacement contact elements must be bent laterally outwards. Can also specified contact arms for an alternating arrangement of conductor pairs with respect to the contacts of the insulation displacement contact elements spread.

Somit kann auch die Anordung der Leiterpaare hier, je nach System, beliebig sein, etwa, dass sich in einer ersten Ebene die Leiter 2, 3, 6 und 7 und sich in einer zweiten Ebene die Leiter 1, 4, 5, 8 von Leiterpaaren erstrecken oder, dass sich in einer ersten Ebene die Leiter 5, 4, 3 und 6 und sich in einer zweiten Ebene die Leiter 8, 7, 2, 1 von Leiterpaaren erstrecken.Depending on the system, the pairs of conductors can also be arranged here as desired be, for example, that in a first level the conductors 2, 3, 6 and 7 and in a second level, the conductors 1, 4, 5, 8 extend from pairs of conductors or that the leaders 5, 4, 3 and 6 on a first level and themselves on a second level the conductors 8, 7, 2, 1 extend from pairs of conductors.

Durch diese Massnahmen werden nunmehr bei einem solchen Hochfrequenzstecker sowohl elektrische (kapazitive) als auch magnetische (induktive) Übersprechkopplungen optimal reduziert, wobei hier insbesondere eine Nebensprechunterdrückung erreicht wird durch eine kürzeste Auflösestrecke der Verdrillung der Leiterpaare, durch Parallelführung der vereinzelten Leiter auf kürzester Strecke ohne Auskreuzung in zwei Ebenen und so mit grossem Leiterabstand und durch Vermeidung von als Kondensator wirksamen Piercing-Kontakten. Zudem gestattet die erfindungsgemässe Anordnung ein leichtes, maschinell mögliches Aufschalten der einzelnen Leiter und einen problemlosen Einbau in einen genormten RJ 45 - Hochfrequenzstecker.These measures now apply to such a high-frequency connector both electrical (capacitive) and magnetic (inductive) crosstalk couplings optimally reduced, especially crosstalk suppression is achieved by a shortest dissolving distance of the twist the pairs of conductors, by routing the individual conductors in parallel to the shortest Route without crossing in two levels and thus with a large conductor spacing and by avoiding piercing contacts that act as a capacitor. In addition, the arrangement according to the invention allows a light, mechanical possible connection of the individual conductors and easy installation into a standardized RJ 45 high frequency connector.

Somit können solche Stecker nunmehr auch für Buchsen ohne spezielle Kompensationsmassnahmen verwendet werden.Such plugs can now also be used for sockets without special compensation measures be used.

Bei einem solchen Kontaktestecker einer Steckverbindung für hochfrequente Datenübertragung über mehrere verdrillte elektrische Leiterpaare eines Kabels sind die Leiter am Kabelende durch Auflösung der Verdrillung vereinzelt und über Drahtanschlussmittel an Kontakten angeschlossen zur lösbaren Verbindung mit korrespondierenden Kontakten des Gegenstückes der Steckerverbindung (nicht gezeigt). With such a contact plug of a connector for high-frequency Data transmission over several twisted pairs of electrical cables the conductors are isolated at the end of the cable by dissolving the twist and Connected to contacts via wire connection means for detachable connection with corresponding contacts of the counterpart of the connector (Not shown).

Ertindungswesentlich ist nun, dass die vereinzelten Leiter der Leiterpaare 1/2, 3/6, 5/4, 7/8 unmittelbar im Kabelaustrittsbereich in vorgegebener Reihenfolge parallel und in zwei Ebenen sowie mit vorgegebenem Abstand zueinander im genannten in den Kontaktstecker einbaubaren Kontaktgehäuse 11 aus nichtleitendem Material geführt und dort je über eine Schneidklemme 9' an einem Schneidklemm-(IDC)-Kontaktelement 9 mit den betreffenden Kontakten 1' bis 8' aufgeschaltet sind, wie das die Fig. 2,3 und 4 mehr im Einzelnen zeigen.It is essential to the invention that the isolated conductors of the conductor pairs 1/2, 3/6, 5/4, 7/8 directly in the cable exit area in the specified order parallel and in two planes as well as with a given distance to each other in mentioned in the contact plug mountable contact housing 11 made of non-conductive Material guided and there each on a cutting clamp 9 ' Insulation displacement (IDC) contact element 9 with the relevant contacts 1 'to 8' are connected, as shown in FIGS. 2, 3 and 4 in more detail.

Durch die Verwendung des Kontaktgehäuses 11 ergibt sich die Möglichkeit, die vereinzelten Leiter in das Kontaktgehäuse beispielsweise maschinell einzulegen, wo sich diese isoliert zwischen Rippen 11' des Kontaktgehäuses erstrecken können. Da sich in diesem Kontaktgehäuse die bereits eingesetzten Schneidklemm-Kontaktelemente 9 in vorgegebener Anordnung befinden, kann auch mit dem Einlegen der Leiter deren Aufschaltung erfolgen.The use of the contact housing 11 gives the possibility of inserting the isolated conductors into the contact housing, for example by machine, where they extend in isolation between ribs 11 'of the contact housing can. Because the insulation displacement contact elements already used are in this contact housing 9 are in a predetermined arrangement, can also with the insertion of the conductors take place.

Hierbei bilden die Kontakte 1' bis 8' der Schneidklemm-Kontaktelemente 9 (Fig. 4) eine Reihe und befinden sich am freien Ende von an den Schneidklemmen 9' abragenden und entsprechend abgebogenen Kontaktarmen 20, wobei zwischen den Kontakten und deren Schneidklemmen ein in Leitererstreckung kürzestmöglicher Abstand besteht.The contacts 1 'to 8' of the insulation displacement contact elements 9 hereby form (Fig. 4) a row and are at the free end of the insulation displacement terminals 9 'protruding and correspondingly bent contact arms 20, wherein between the contacts and their insulation displacement terminals in a conductor extension shortest possible distance.

Diese Schneidklemm-Kontaktelemente 9 sind im wesentlichen starr ausgebildet.These insulation displacement contact elements 9 are essentially rigid.

Bei der erfindungsgemässen Anordnung nach den Fig. 2, 3 und 4 erstrecken sich die Leiter 2, 3, 6 und 7 von den Leiterpaaren 1/2, 3/6, 5/4, 7/8 in einer ersten Ebene und die Leiter 1, 4, 5, 8 in einer zweiten Ebene.2, 3 and 4 extend in the arrangement according to the invention the conductors 2, 3, 6 and 7 of the conductor pairs 1/2, 3/6, 5/4, 7/8 in a first Level and the ladder 1, 4, 5, 8 in a second level.

Je nach System können sich aber auch u.a. die Leiter 5,4,3 und 6 von den Leiterpaaren 1/2, 3/6, 5/4, 7/8 in einer ersten Ebene und die Leiter 8, 7, 2 und 1 in einer zweiten Ebene erstrecken, wie das in Fig. 5 veranschaulicht ist. Entsprechend übergreifen sich vorgegebene Kontaktarme 20' für die wechselnde Anordnung der Leiterpaaren bezüglich der Kontakte der Schneidklemm-Kontaktelemente 9.Depending on the system, the conductors 5, 4, 3 and 6 from the pairs of conductors 1/2, 3/6, 5/4, 7/8 in a first level and conductors 8, 7, 2 and 1 in a second level, as illustrated in FIG. 5. Corresponding predetermined contact arms 20 'overlap for the changing arrangement the pairs of conductors with respect to the contacts of the insulation displacement contact elements 9.

Für weitere Ausführungsformen ist es möglich, dass sich gemäss Fig. 6 für das Aufschalten randnaher Leiter die betreffenden Schneidklemm-Kontaktelemente 9 seitlich nach aussen gebogen sind.For further embodiments, it is possible for the Connection of the insulation displacement contact elements 9 near the edge are bent outwards laterally.

Eine Anzahl möglicher Ausgestaltungen von Schneidklemm-Kontaktelementen 9, beispielsweise für die Kontaktsätze gemäss den Fig. 4, 5 und 6 sind in Fig. 7 angedeutet.A number of possible configurations of insulation displacement contact elements 9, for example for the contact sets according to FIGS. 4, 5 and 6 are indicated in FIG. 7.

Aus dem Vorstehenden ergibt sich so ein Steckverbindungsteil, insbesondere Hochfrequenzstecker, bei welchem sowohl elektrische (kapazitive) als auch magnetische (induktive) Übersprechkopplungen optimal reduziert werden.From the above, a plug-in connection part results, in particular High-frequency connector, in which both electrical (capacitive) and magnetic (inductive) crosstalk couplings can be optimally reduced.

Insbesondere wird hier eine Nebensprechunterdrückung erreicht durch eine kürzeste Auflösestrecke der Verdrillung der Leiterpaare, durch Parallelführung der vereinzelten Leiter auf kürzester Strecke ohne Auskreuzung in zwei Ebenen und so mit grossem Leiterabstand und durch Vermeidung von als Kondensator wirksamen Piercing-Kontakten. Zudem gestattet die erfindungsgemässe Anordnung ein leichtes, maschinell mögliches Aufschalten der einzelnen Leiter und einen problemlosen Einbau in einen genormten RJ 45 - Hochfrequenzstecker oder dgl..In particular, crosstalk suppression is achieved here by means of the shortest Resolving distance of the twisting of the pairs of conductors, through parallel guidance the isolated ladder over the shortest distance without crossing in two levels and so with a large conductor spacing and by avoiding as a capacitor effective piercing contacts. In addition, the arrangement according to the invention allows an easy, mechanically possible connection of the individual conductors and easy installation in a standardized RJ 45 high frequency connector or the like ..

Selbstverständlich sind weitere Ausführungsvarianten denkbar, ohne den Erfindungsgedanken hierfür zu verlassen. Insbesondere sind anstelle der hier bevorzugten IDC-Drahtanschlussmittel auch andere Anschlussmittel möglich.Of course, further design variants are conceivable without the inventive concept to leave for this. In particular, instead of the preferred ones here IDC wire connection means also other connection means possible.
