Description

Die Erfindung betrifft eine Buchse und eine Anschlussdose zur Herstellung einer Hochleistungs-Datenleitungsverbindung mit einer solche Buchse nach Anspruch 1 bzw. 9.The invention relates to a socket and a junction box for producing a high performance data line connection with such a socket according to claim 1 or 9.

Zur Herstellung einer Datenleitungsverbindung von einem Server zu einem Endgerät (Channel) bzw. zwischen den entsprechenden Anschlussdosen (Link) mit hoher Datenübertragungskapazität müssen sämtliche Komponenten des Channels bzw. Links, insbesondere Datenkabel und Anschlussdosen, gewisse Mindestanforderungen in Bezug auf ihre Übertragungseigenschaften erfüllen. Die Komponenten werden gemäss ihren Übertragungseigenschaften in verschiedene Kategorien eingeteilt, von denen derzeit die Kategorien 5, 5e und 6 von besonderem Interesse sind. Es ist geplant, die Spezifikationen für Komponenten der betreffenden Kategorien zu normieren. Nach einem solchen Normierungs-vorschlag müssen Kabel der Kategorien 5, 5e und 6 Kabel bei 100 MHz das Nahnebensprechen (Near End Cross Talk bzw. NEXT) mit 32.3, 35.3 bzw. 44.3 dB unterdrücken. Für Anschlussdosen der Kategorien 5, 5e und 6 gelten für NEXT-Verluste bei 100 MHz Werte von 40, 43 bzw. 54 dB. Die Anforderungen der Klassen 5, 5e und 6 können derzeit für Kabel verhältnismässig gut erfüllt werden, für Anschlussdosen insbesondere der Kategorie 6 existiert jedoch keine befriedigende Lösung.For producing a data line connection of a Server to a terminal (channel) or between the corresponding junction boxes (link) with high data transmission capacity need all the components of Channels or links, especially data cables and Junction boxes, certain minimum requirements regarding fulfill their transmission properties. The components become different according to their transmission properties Categories, of which currently the Categories 5, 5e and 6 are of particular interest. It is planned, the specifications for components of the to normalize the categories concerned. After such a Standardization proposal must have Category 5, 5e cables and 6 cables at 100 MHz near end crosstalk (Near End Cross Talk or NEXT) with 32.3, 35.3 and 44.3 dB respectively suppress. For junction boxes of categories 5, 5e and 6 apply to NEXT losses at 100 MHz values of 40, 43 or 54 dB. The requirements of classes 5, 5e and 6 can currently be met relatively well for cables for junction boxes, in particular category 6 However, there is no satisfactory solution.

Anschlussdosen umfassen üblicherweise wenigstens eine Buchse, z.B. eine RJ45-Buchse, mit einem Aufnahmeelement für den Stecker eines Datenkabels und einer Mehrzahl von hakenförmig gebogenen, länglichen Kontaktelementen, die sich über einen Grossteil der Länge des Aufnahmeelements erstrecken und im Anwendungsfall mit den einzelnen Leitungen des Datenkabels bzw. den entsprechenden Kontaktelementen am Stecker in Kontakt stehen. Die Buchse ist auf einer Basisleiterplatte befestigt, die Leitungsverbindungen zu einer Anschlussleiste für ein weiteres, in der Regel stationäres Datenkabel enthält. Jeweils ein Ende der hakenförmigen Kontaktelemente der Buchse ist aus dem Aufnahmeelement hinausgeführt und direkt mit der Basisleiterplatte bzw. einer Leitungsverbindung darauf verlötet. Bei bekannten Konstruktionen befinden sich die elektrisch leitfähigen Komponenten ohne Abschirmung in unmittelbarer räumlicher Nähe zueinander und stören sich gegenseitig. RJ45-Buchsen haben 8 nebeneinander liegende Kontaktelemente für die 4 Paare von Leitungen der entsprechenden Datenkabel. Jeweils ein Leitungspaar ist den Kontaktelementen 1/2, 4/5 und 7/8 zugeordnet, ein weiteres Leitungspaar entfällt auf die Kontaktelemente 3 und 6. Aufgrund dieser räumlichen Anordnung sind die Störungen zwischen dem Paar 3/6 und 4/5 besonders gross.Junction boxes usually comprise at least one Socket, e.g. an RJ45 socket, with a receiving element for the connector of a data cable and a plurality of hook-shaped, elongated contact elements, the over a majority of the length of the receiving element extend and in the case of use with the individual Lines of the data cable or the corresponding Contact elements on the connector in contact. The socket is mounted on a base board, the line connections to a terminal block for another, in usually contains stationary data cable. One end each the hook-shaped contact elements of the socket is made of the Receiving element led out and directly with the Base circuit board or a line connection on it soldered. In known constructions are the electrically conductive components without shielding in immediate spatial proximity to each other and interfere each other. RJ45 jacks have 8 juxtaposed Contact elements for the 4 pairs of wires corresponding data cable. Each is a pair of wires assigned to the contact elements 1/2, 4/5 and 7/8, a another line pair is attributable to the contact elements. 3 and 6. Due to this spatial arrangement are the Disturbances between the pair 3/6 and 4/5 particularly large.

Es ist zur Störungsverminderung bekannt, die Basisleiterplatte mit einer Kompensationsschaltung auszustatten, die einzelne Leitungen bzw. Leitungspaare gegeneinander entkoppelt, z.B. kapazitiv. Anschlussdosen mit derartigen Kompensationsschaltung erfüllen in der Regel die Anforderungen der Kategorie 5 oder 5e. Zum Sprung in die Kategorie 6 ist jedoch eine Verbesserung um 11 dB bei 100 MHz erforderlich, die mit dem geschilderten Design bisher nicht realisiert wurde.It is known for mitigation, the base board equipped with a compensation circuit, the individual lines or pairs of lines are decoupled from each other, e.g. capacitive. Junction boxes with such Compensation circuit usually meet the requirements category 5 or 5e. To jump into the Category 6, however, is an improvement of 11 dB at 100 MHz required with the described design so far was not realized.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Buchse und eine Anschlussdose mit verbesserten Übertragungseigenschaften anzugeben. Die Buchse soll vorzugsweise die Geometrie bereits verwendeter Buchsen aufweisen, insbesondere gemäss RJ45, um mit gängigen Standard-Steckern kompatibel zu sein.The invention is therefore based on the object, a Socket and a junction box with improved transmission characteristics indicated. The socket should preferably have the geometry of already used sockets, especially in accordance with RJ45, with standard plug connectors to be compatible.

Die Aufgabe wird gelöst durch eine Buchse mit den Merkmalen von Anspruch 1 sowie durch eine Anschlussdose mit den Merkmalen von Anspruch 9. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüche, der Beschreibung und den Zeichnungen.The problem is solved by a socket with the Features of claim 1 and by a junction box with the features of claim 9. Advantageous developments The invention will become apparent from the dependent Claims, the description and the drawings.

Der Erfindung liegt die überraschende Erkenntnis zugrunde, dass auch Strukturen unterhalb von 1/10 der Wellenlänge der betreffenden Signale einen Einfluss auf die wechselseitigen Störungen haben. Die Verlagerung der Kompensationsschaltung von der Basisleiterplatte in unmittelbare räumliche Nähe der Kontaktelemente der Buchse führt zu einer deutlich verbesserten Kompensation insbesondere der NEXT Werte. Diese Effekt wird verstärkt durch eine Verkürzung der Länge der Kontaktelemente bzw. der Signalwege von den Kontaktelementen des Steckers bis zur Kompensationsschaltung bzw. zu den Anschlüssen eines weiteren Kabels. Die Signale verlassen die Buchse bereits kompensiert und müssen auf der Basisleiterplatte nicht oder weniger aufwendig korrigiert werden.The invention is based on the surprising finding that also structures below 1/10 of the wavelength the signals in question have an influence on the mutual Have disorders. The relocation of Compensation circuit from the base board in immediate spatial proximity of the contact elements of the socket leads to a significantly improved compensation especially the NEXT values. This effect is amplified by a shortening of the length of the contact elements or the signal paths from the contact elements of the plug up to the compensation circuit or to the terminals of a another cable. The signals already leave the socket compensated and do not need to on the base board or less expensive to be corrected.

Erfindungsgemäss sind die Kontaktelemente einer Buchse an einer Kompensationsleiterplatte befestigt, die eine Kompensationsschaltung zur Verminderung von Störeinflüssen, insbesondere Übersprecheinflüssen, zwischen Leitungen enthält und die innerhalb des Aufnahmeelements für den Stecker angeordnet ist. Die Kontaktelemente der Buchse können sehr kurz ausgebildet werden, da sie nur von den Kontaktelementen des Steckers bis zur Kompensationsleiterplatte reichen und nicht wie beim Stand der Technik aus der Buchse bzw. dem Aufnahmeelement hinausgeführt werden müssen. Die Stärke der gegenseitigen Störungen zwischen den Signalwegen, insbesondere des gegenseitigen Übersprechens, wird vermindert. Schliesslich kann die Kompensationsschaltung auf der Kompensationsleiterplatte vereinfacht werden, z.B. durch Verwendung von Kondensatoren mit geringeren Kapazitäten.According to the invention, the contact elements to a socket a compensation printed circuit board attached, the one Compensation circuit for the reduction of disturbing influences, especially crosstalk, between Contains lines and the inside of the receiving element is arranged for the plug. The contact elements of Socket can be made very short, since it only from the contact elements of the plug to Kompensationsleiterplatte rich and not as in the prior art led out of the socket or the receiving element Need to become. The strength of mutual interference between the signal paths, especially the mutual Crosstalk is reduced. Finally, the Compensation circuit on the compensation PCB be simplified, e.g. through use of Capacitors with lower capacities.

Die Kompensationsleiterplatte kann in beliebige Buchsen integriert werden, deren Aufnahmeelement insbesondere an Stecker mit an sich bekannter Form angepasst ist. Damit werden Kompatibilitätsprobleme beim Umstellen auf Komponenten der Kategorie 6 vermieden. Vorzugsweise werden Aufnahmeelemente bzw. Buchsen verwendet, die der RJ45-Form entsprechen. Die Kompensationsleiterplatte erstreckt sich beispielsweise über die Bodenfläche des Aufnahmeelementes oder bildet die Bodenfläche. Sie kann herausnehmbar sein. Vorzugsweise sind Montageelemente zur Befestigung auf der Basisleiterplatte vorhanden, besonders bevorzugt erlauben sie die Befestigung in verschiedenen Stellungen relativ zu dieser.The compensation PCB can be used in any sockets be integrated, the receiving element in particular Plug is adapted with a known form. In order to will have compatibility issues when switching to Category 6 components avoided. Preferably Receptacles or jacks used that the RJ45 shape correspond. The compensation PCB extends for example, over the bottom surface of the receiving element or forms the bottom surface. It can be removable. Preferably, mounting elements for attachment to the Base PCB available, allow more preferably they attach to different positions relative to this.

Die Anschlussdose umfasst neben wenigstens einer erfindungsgemässen Buchse eine Basisleiterplatte und eine Anschlussleiste. Es können weitere Elemente vorhanden sein, z.B. zur Bildung eines vorzugsweise abgeschirmten Gehäuses. Das Gehäuse kann auf bekannte Weise gestaltet sein, z.B. gemäss EP-A 0928052.The junction box includes at least one Socket according to the invention, a base circuit board and a Terminal strip. There may be more items available be, e.g. to form a preferably shielded Housing. The housing can be designed in a known manner be, e.g. according to EP-A 0928052.
