BeschreibungDescription
Die Erfindung betrifft eine Anordnung zum Verbinden des Schirmgeflechtes von Kabeln mit Metallgehäusen von Baugruppenträgern.The invention relates to an arrangement for connecting the shielding braid of cables to metal housings of subracks.
Anlagen, z. B. der Telekommunikationstechnik werden in Baugruppenträgern angeordnet, die gegen äußere Störbeeinflussungen als Faradaysche Käfige ausgebildet sind. Zur elektrischen Verbindung mehrerer Baugruppenträger untereinander und/oder mehrerer Gehäusemodule werden geschirmte Kabel verwendet. Das Schirmgeflecht dieser Kabel ist bei dessen Heraus- oder Hereinführen aus bzw. in einen Faradayschen Käfig mit dessen die Masse führenden Teilen zu verbinden.Systems, e.g. in telecommunications technology, are arranged in subracks that are designed as Faraday cages to protect against external interference. Shielded cables are used to electrically connect several subracks to each other and/or several housing modules. The braided shield of these cables must be connected to the parts that carry the ground when leading them out of or into a Faraday cage.
Aufgabe der vorliegenden Erfindung war es, eine sichere Massekontaktierung zwischen Schirmgeflecht eines Kabels und dem Gehäuse und/oder dem Baugruppenträger zu schaffen, die einfach zu installieren ist.The object of the present invention was to create a secure ground contact between the braided shield of a cable and the housing and/or the module carrier that is easy to install.
Diese Aufgabe ist durch die Erfindung gelöst, wie sie im Kennzeichnungsteil des ersten Schutzanspruches dargelegt ist. Weitere vorteilhafte Maßnahmen sind Gegenstand der Unteransprüche.This object is achieved by the invention as set out in the characterizing part of the first claim. Further advantageous measures are the subject of the subclaims.
Anhand einer aus drei Figuren bestehenden Zeichnung wird die Erfindung näher erläutert. In der Zeichnung zeigen dieThe invention is explained in more detail using a drawing consisting of three figures. In the drawing, the
Fig. 1 ein geschirmtes Kabelende mit den erfindungsgemäßFig. 1 a shielded cable end with the inventive
verwendeten zusätzlichen Teilen, die Fig. 2 ein Kabelende mit angeschlossenem Buchsenstecker undused additional parts, Fig. 2 a cable end with connected socket plug and
einer Befestigungsfeder und die Fig. 3 die Befestigung eines Kabelendes an einen Baugruppenträger.a fastening spring and Fig. 3 shows the fastening of a cable end to a subrack.
Ein Kabel mit Schintigeflecht besteht aus einer Anzahl von Kabelleitern 1, die vom Schirmgeflecht 2 umhüllt sind und dem Kabelmantel 3. Um das Schirmgeflecht 2 eines solchen Kabels mit einer möglichst großen Fläche von Teilen eines Metallgehäuses von Baugruppenträgern in Kontakt zu bringen, insbesondere für Kabel, über die Bus-Leitungen geführt werden, wird das Kabel an beiden Enden abgemantelt und mit einer zweigeteilten Hülse 4, bestückt. Der innere Teil 4 wird unter und der äußere Teil 5 über das Schirmgeflecht 2 geschoben. Durch Verformen des äußeren Teils 5 durch Verpressung wird eine nicht lösbare Verbindung und sichere Kontaktierung erzielt. Die sichere Kontaktierung wird durch entsprechende Materialwahl erreicht. Der innere Teil besteht vorzugsweise aus Kupfer mit verzinnter Oberfläche. Er ist zudem mehrfach eingeschnitten. Für den äußeren Teil wird vorzugsweise eine Kupfer-Zink-Legierung verwendet, deren Oberfläche vernickelt und mit einer Zinnschicht überzogen ist.A cable with a Schintig braid consists of a number of cable conductors 1, which are covered by the shield braid 2 and the cable sheath 3. In order to bring the shield braid 2 of such a cable into contact with as large an area as possible of parts of a metal housing of module carriers, in particular for cables over which bus lines are routed, the cable is stripped at both ends and fitted with a two-part sleeve 4. The inner part 4 is pushed under and the outer part 5 over the shield braid 2. By deforming the outer part 5 by pressing, a non-detachable connection and secure contact is achieved. Secure contact is achieved by choosing the appropriate material. The inner part is preferably made of copper with a tinned surface. It is also cut several times. For the outer part, a copper-zinc alloy is preferably used, the surface of which is nickel-plated and covered with a layer of tin.
Nach der Montage von Steckern 6, im gezeigten Beispiel der Figur 2 ein 20-poliger Buchsenstecker, wird über die zweiteilige Hülse 4, 5 ein handelsüblicher blankverzinkter Kabelbefestiger 7 mit Druckfederwirkung geschoben. Der Kabelbefestiger 7 wird in eine Lochung 8 eines Wandbleches des Baugruppenträgers 9 eingerastet. Durch die Federkraft und die breite Auflagefläche des Kabelbefestigers 7 wird zwischen Hülse 4, 5 und Baugruppenträger 9 ein sicherer Kontakt gewährleistet.After the assembly of plugs 6, in the example shown in Figure 2 a 20-pin socket plug, a commercially available bright galvanized cable fastener 7 with a compression spring effect is pushed over the two-part sleeve 4, 5. The cable fastener 7 is snapped into a hole 8 in a wall plate of the module carrier 9. The spring force and the wide contact surface of the cable fastener 7 ensure a secure contact between the sleeve 4, 5 and the module carrier 9.
