Abstract

The invention relates to a regular jack (RJ) connector for information and data technology, having contacts of the insulation-displacement technology type. The object, namely to develop a regular jack connector which is substantially improved with respect to its electrical parameters and which corresponds to category 5 of the technical requirements for cable and connector technology (EIA), is achieved through the fanning-out of the individual contacts in the regular jack connector and their extension to the insulation-displacement (LSA) contacts, which are arranged set back, on two levels.

Description

Die Erfindung bezieht sich auf einen RJ-Verbinder für die Nachrichten- und Datentechnik gemäß dem Oberbegriff des Anspruches 1.The invention relates to an RJ connector for communications and data technology according to the preamble of claim 1.

In der Schneid-Klemm-Technik sind zur Sprach- und Datenübertragung RJ-Verbinder (Regular Jack) bekannt, bei denen RJ-Kontakte über lange Wege mit sehr geringen Abständen voneinander parallel zueinander geführt sind (LSA PLUS Kabelanschlußtechnik der KRONE AG: Planungshinweise, Ausgabe 06.92, KRONE LINK mit LSA-PROFIL). Dadurch entsteht eine Kondensatorwirkung zwischen den Kontaktbahnen, die zu einer Verschlechterung einiger elektrischer Kennwerte der Verbinder führt. Die Werte der Nebensprechdämpfung/Übersprechdämpfung erfüllen nicht die Anforderungen, wenn ihre Verwendung in Hochgeschwindigkeitsnetzen vorgesehen ist (CDDI/FDDI-Anordnungen: Cooper Distributed Data Interface/Fiber Distributed Data Interface). Die inneren Kontakte der RJ-Verbinder sind zudem in der Materialstärke und der Materialqualität unterschiedlich zu den äußeren Kontakten der Schneid-Klemm-Technik ausgebildet. Die Verbindung zwischen den inneren und äußeren Kontakten ist bei den bekannten Verbindern durch Löten oder Schweißen oder über Leiterplatten/Leiterkarten hergestellt. Die damit entstandenen Übergangsstellen bewirken ebenfalls eine negative Beeinflussung einiger elektrischer Kennwerte der Verbinder. Die Sprach- und Datenübertragung über Übertragungswege mit 100 MBit/s bzw. der Einsatz von RJ-Verbindern im Frequenzbereich von 20 bis 100 MHz stellt u.a. an die Nebensprechdämpfung, Einfügungsdämpfung und Reflexionsdämpfung sehr hohe Anforderungen, die durch die bekannten RJ-Verbinder nicht erfüllt werden.RJ-connectors (regular jacks) are known in insulation displacement technology for voice and data transmission, in which RJ contacts are routed parallel to each other over long distances with very small distances (LSA PLUS cable connection technology from KRONE AG: planning information, output 06.92, KRONE LINK with LSA PROFILE). This creates a capacitor effect between the contact tracks, which leads to a deterioration in some electrical characteristics of the connectors. The values of crosstalk attenuation / crosstalk attenuation do not meet the requirements if their use is intended in high-speed networks (CDDI / FDDI arrangements: Cooper Distributed Data Interface / Fiber Distributed Data Interface). The inner contacts of the RJ connectors are also different in material thickness and material quality than the outer contacts of the insulation displacement technology. The connection between the inner and outer contacts is made in the known connectors by soldering or welding or via printed circuit boards / printed circuit boards. The resulting transition points also have a negative influence on some electrical characteristics of the connectors. The voice and data transmission via transmission paths with 100 Mbit / s or the use of RJ connectors in the frequency range from 20 to 100 MHz places very high demands on the crosstalk attenuation, insertion loss and reflection attenuation, which are not met by the known RJ connectors .

Der Erfindung liegt von daher die Aufgabe zugrunde, einen RJ-Verbinder der gattungsgemäßen Art zu entwickeln, der in seinen elektrischen Parametern wesentlich verbessert ist und welcher der Kategorie 5 der technischen Anforderungen für Kabel und Verbindertechnik (EIA) entspricht.The invention is therefore based on the object of developing an RJ connector of the generic type which is significantly improved in its electrical parameters and which corresponds to Category 5 of the technical requirements for cables and connector technology (EIA).

Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruches 1.The solution to this problem results from the characterizing features of claim 1.

Durch die Auffächerung der im vorher bestimmten Rastermaß parallel geführten Einzelkontakte im RJ-Verbinder und deren Weiterführung zu Kontakten der Schneid-Klemm-Technik auf zwei Ebenen wird eine optimierte Anordnung der RJ-Kontakte und damit eine wesentliche Verbesserung der elektrischen Parameter des RJ-Verbinders erreicht. Die Verbesserung der elektrischen Parameter, insbesondere der Dämpfungswerte, resultiert aus dem Wegfall jeglicher Übergangsstellen in der Kontaktführungsbahn, da die Kontaktfedern direkt in einen der Doppelkontakte der Schneid-Klemm-Technik für den Kabelanschluß geführt sind (LSA-Kontakte). Es entfallen Löt- oder Schweißverbindungen und Materialunterschiede in der Kontaktbahn. Des weiteren sind die Kontaktführungen kürzer und die Abstände zwischen den Kontakten im vorgegebenen Rahmen maximiert. Dadurch werden die Koppelkapazitäten zwischen den Kontaktbahnen minimiert. Die Verwendung von ausschließlicher Schneid-Klemm-Technik (LSA PLUS) ermöglicht des weiteren, daß auf der Kabelanschlußseite des Verbinders Adern mit unterschiedlichem Durchmesser angeschlossen werden können. Die erfindungsgemäßen Maßnahmen machen die RJ-Verbinder tauglich für die Anwendung in CDDI-Anordnungen.By fanning out the individual contacts in the RJ connector, which are guided in parallel in the predetermined grid dimension, and extending them to contacts of the insulation displacement technique on two levels, an optimized arrangement of the RJ contacts and thus a substantial improvement in the electrical parameters of the RJ connector is achieved . The improvement in the electrical parameters, in particular the damping values, results from the Elimination of any transition points in the contact guide track, since the contact springs are led directly into one of the double contacts of the insulation displacement technology for the cable connection (LSA contacts). There are no soldered or welded connections and material differences in the contact path. Furthermore, the contact guides are shorter and the distances between the contacts are maximized within the given frame. This minimizes the coupling capacities between the contact tracks. The use of exclusive insulation displacement technology (LSA PLUS) also enables wires with different diameters to be connected on the cable connection side of the connector. The measures according to the invention make the RJ connectors suitable for use in CDDI arrangements.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention result from the subclaims.

Die Fig. 1 zeigt in schematischer Darstellung eine Seitenansicht der Grundanordnung der Einzelkontakte eines RJ-Verbinders 1 kombiniert mit Doppelkontakten 3 der Schneid-Klemm-Technik (LSA PLUS) für unterschiedliche Durchmesser der Adern 7 eines anzuschließenden Kabels 4. Die übereinander bzw. parallel im definierten Rastermaß für RJ-Verbinder 1 geführten Kontaktfedern 2 sind am Eingang des Doppelkontaktes 3 in zwei Ebenen mit jeweils vier oberen und unteren Kontakten 5,6 aufgeteilt und in die unteren Kontakte 5 von vier Doppelkontakten 3 der Schneid-Klemm-Technik (LSA PLUS) geführt. Die Kontaktfedern 2 der RJ-Verbinder 1 haben einheitliche Abmessungen. Die oberen Kontakte 6 der Doppelkontakte 3 sind so ausgebildet, daß unterschiedliche Durchmesser von Adern 7 des horizontal herangeführten Kabels 4 kontaktiert werden können. Mit der Anordnung gemäß Fig. 1 ist eine achtdrähtige Kontaktierung realisierbar.1 shows a schematic representation of a side view of the basic arrangement of the individual contacts of an RJ connector 1 combined with double contacts 3 of insulation displacement technology (LSA PLUS) for different diameters of the wires 7 of a cable 4 to be connected Defined pitch for RJ connectors 1 guided contact springs 2 are divided at the input of the double contact 3 into two levels, each with four upper and lower contacts 5,6 and into the lower contacts 5 of four double contacts 3 of the insulation displacement technology (LSA PLUS) guided. The contact springs 2 of the RJ connector 1 have uniform dimensions. The upper contacts 6 of the double contacts 3 are designed so that different diameters of wires 7 of the horizontally guided cable 4 can be contacted. With the arrangement according to FIG. 1, an eight-wire contact can be implemented.

Durch diese versetzte Kontaktführung werden die Abstände zwischen den Kontakten 2 des RJ-Verbinders 1 maximiert, so daß verbesserte Werte des Verbinders 1 bezüglich der Dämpfung, insbesondere der Übersprechdämpfung, durch die Minimierung der Koppelkapazitäten erreicht werden. Die durchgehende Verwendung der Schneid-Klemm-Technik (LSA-Technik) für das Kontaktieren der RJ-Kontakte 2 und zum Kontaktieren der Kabeladern 7 ermöglicht eine weitere Optimierung der Kontaktführung durch den Fortfall jeglicner Schweiß- oder Löttechnik. Insgesamt werden für den Verbinder 1 elektrische Parameter erreicht, die den CDDI-Anordnungen genügen.This offset contact routing maximizes the distances between the contacts 2 of the RJ connector 1, so that improved values of the connector 1 with regard to the attenuation, in particular the crosstalk attenuation, are achieved by minimizing the coupling capacitances. The continuous use of insulation displacement technology (LSA technology) for contacting the RJ contacts 2 and for contacting the cable wires 7 enables the contact to be further optimized by eliminating any welding or soldering technology. Overall, electrical parameters are achieved for the connector 1 which satisfy the CDDI arrangements.

Die Fig. 2 zeigt in schematischer Darstellung die Rückseite eines RJ-Verbinders 1. Die innere Seite 9 des Verbinders 1 weist 8 Doppelkontakte 3 in Schneid-Klemm-Technik (LSA PLUS) auf, die zum Anschluß der 8 RJ-Kontakte 2 dienen.Fig. 2 shows a schematic representation of the back of an RJ connector 1. The inner side 9 of the connector 1 has 8 double contacts 3 in insulation displacement technology (LSA PLUS), which are used to connect the 8 RJ contacts 2.

Die innere Seite 9 des Verbinders 1 ist dem Anwender nicht zugänglich. Die versetzte Anordnung der Doppelkontakte 3 vergrößert auch hier den Abstand zwischen den RJ-Kontakten 2, so daß sich die Koppelkapazitäten zwischen den Einzeladern 7 verringern.The inner side 9 of the connector 1 is not accessible to the user. The offset arrangement of the double contacts 3 also increases the distance between the RJ contacts 2, so that the coupling capacitances between the single wires 7 decrease.

In der Fig. 3 ist in schematischer Darstellung die Draufsicht auf die Kontaktführung in dem Verbinder 1 nach Fig. 2 gezeigt, bei dem durch die Auffächerung der RJ-Kontakte 2 und durch die versetzte Anordnung der Doppelkontakte 3 die Bedingungen für eine verbesserte Übertragung von Daten und Sprache bei gleichzeitiger Verkleinerung der Einbaumaße des RJ-Verbinders 1 durch die Vermeidung einer Leiterkarte geschaffen sind.3 shows a schematic representation of the top view of the contact guide in the connector 1 according to FIG. 2, in which the conditions for an improved transmission of data are achieved by the fanning out of the RJ contacts 2 and by the offset arrangement of the double contacts 3 and speech with a simultaneous reduction in the installation dimensions of the RJ connector 1 by avoiding a printed circuit board.

Die Fig. 4 zeigt eine schematische Draufsicht auf einen Verbinder 1 mit zwei Doppelkontakten 3 pro RJ-Kontakt 2. Mit der Implementierung eines zweiten Kontaktes 32 pro RJ-Kontakt 2 ist die ISDN-Nutzung des Verbinders 1 gewährleistet.FIG. 4 shows a schematic top view of a connector 1 with two double contacts 3 per RJ contact 2. The implementation of a second contact 32 per RJ contact 2 ensures the ISDN use of the connector 1.

In den Fig. 3 und 4 ist eine paarige Aderzuordnung vorgesehen.3 and 4, a paired wire assignment is provided.
