Description
Verbindungsanordnung zwischen einem Koax-Kabel und den Messern einer Rückwand-Verdrahtungsplatte innerhalb eines Baugruppenrahmens, bei der die Rückwand-Verdrahtungsplatte durchgehend mit im Rechteckmuster angeordneten Kontaktmessern bestückt ist und jeweils ein ein elektrisches Signal führendes Kontaktmesser von mit Schirmpotential verbundenen Kontaktmessern umgeben ist, wobei mittels eines Steckers der Innenleiter des Kabels über eine innerhalb des Steckers angeordnete Kontaktfeder mit dem signalführenden Kontaktmesser und der Geflechtschirm des Kabels über im vorderen Bereich des Steckers angeordneten Federzungen mit den auf Schirmpotential liegenden Kontaktmessern verbunden ist.Connection arrangement between a coax cable and the knives of a rear wall wiring board within a module frame, in which the rear wall wiring board is continuously equipped with contact knives arranged in a rectangular pattern and in each case a contact knife carrying an electrical signal is surrounded by contact knives connected to shielding potential, whereby by means of a Plug of the inner conductor of the cable is connected to the signal-carrying contact knife via a contact spring arranged inside the plug, and the braided shield of the cable is connected to the contact knives located at shield potential via spring tongues arranged in the front region of the plug.
Immer häufiger tritt das Problem auf, daß ein Koax-Kabel elektrisch mit Leitungen einer Rückwand-Verdrahtungsplatte verbunden werden muß. Dazu wurden in der Regel herkömmliche und teure Koax-Stecker eingesetzt, die direkt mitsamt der Baugruppe gesteckt wurden und aufgrund ihrer Größe hierfür in der Rückwand-Verdrahtungsplatte ein verhältnismäßig großes Loch benötigten. Da immer größere Datenmengen immer schneller und sicherer zu transportieren sind, gewinnt das Problem der Schirmung immer größere Bedeutung. Daher sind Durchführungslöcher in der RückwandVerdrahtungsplatte bei einer großen Anzahl von Koax-Steckern sehr nachteilig, da dies zu großen Auflösungs- und Schirmungsproblemen führt.The problem arises more and more frequently that a coax cable must be electrically connected to lines of a rear wall wiring board. For this purpose, conventional and expensive coax plugs were generally used, which were plugged in directly together with the module and, due to their size, required a relatively large hole in the rear wall wiring plate. Since ever larger amounts of data can be transported faster and more safely, the problem of shielding is becoming increasingly important. Therefore, through holes in the backplane wiring board are very disadvantageous with a large number of coax connectors, since this leads to large resolution and shielding problems.
Aus der US-A-4 494 816 ist eine Verbindungsanordnung der eingangs genannten Art bekannt, welche diese Nachteile nicht aufweist und die eine einfache Verbindung von Koax-Kabeln mit den Messern einer Rückwand erlaubt, ohne daß ein zusätzlicher Eingriff z.B. in Form eines Durchbruchs in die Rückwand-Verdrahtungsplatte vorgenommen werden muß, und bei der für jede Verbindung eine ausreichende Schirmung gewährleistet ist.From US-A-4 494 816 a connection arrangement of the type mentioned is known, which does not have these disadvantages and which allows a simple connection of coaxial cables to the knives of a rear wall, without additional intervention, for example in the form of an opening in the backplane wiring board must be made and sufficient shielding is guaranteed for each connection.
Nachteilig bei dieser bekannten Verbindungsanordnung ist, daß die Verbindung keine Zugkräfte, welche auf das Kabel ausgeübt werden, auffangen kann. Bei Auftreten einer derartigen Zugkraft kann die Verbindung unbeabsichtigt gelöst werden.A disadvantage of this known connection arrangement is that the connection cannot absorb any tensile forces which are exerted on the cable. If such a tensile force occurs, the connection can be unintentionally released.
Aufgabe der vorliegenden Erfindung ist es, eine Verbindungsanordnung der eingangs genannten Art anzugeben, welche in der Lage ist, am Kabel angreifende Zugkräfte aufzunehmen.The object of the present invention is to provide a connection arrangement of the type mentioned at the outset which is capable of absorbing tensile forces acting on the cable.
Diese Aufgabe wird für eine Verbindungsanordnung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß das signalführende Kontaktmesser durch einen Durchbruch eines auf der Rückwand-Verdrahtungsplatte aufliegenden Rastknopfs, welcher fest mit dem das elektrische Signal führenden Kontaktmesser verbunden ist, hindurchragt, und daß der Stecker auf dem Rastknopf aufrastbar ist, wobei der Geflechtschirm des Kabels über einen zwischen einer äußeren Quetschhülse und dem Kunststoffgehäuse des Steckers angeordneten gefiederten Federkranz mit den Federzungen verbunden ist, welche offen nach außen abgebogen sind.This object is achieved according to the invention for a connection arrangement of the type mentioned at the outset in that the signal-carrying contact knife protrudes through an opening in a latching button resting on the rear wall wiring plate, which is firmly connected to the contact knife carrying the electrical signal, and in that the plug on the Locking button can be snapped on, the braided shield of the cable being connected to the spring tongues, which are openly bent outwards, via a feathered spring collar arranged between an outer crimp sleeve and the plastic housing of the plug.
Mit Hilfe der erfindungsgemäßen Verbindungsanordnung ist es auf einfache Weise möglich, eine Verbindung zwischen einem Koax-Kabel und den Leitungen einer Rückwand-Verdrahtungsplatte zu schaffen, bei welcher auf das Kabel einwirkende Zugkräfte nicht zu einer unbeabsichtigten Trennung der Verbindung führen.With the help of the connection arrangement according to the invention, it is possible in a simple manner to create a connection between a coax cable and the lines of a rear wall wiring board, in which tensile forces acting on the cable do not lead to an unintentional disconnection of the connection.
Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Verbindungsanordnung ist dadurch gekennzeichnet, daß der Rastknopf in seinem vorderen Bereich einen nach außen gerichteten kreisförmigen Wulst aufweist, welcher von einem am Kopf des Steckers befindlichen Federkranz umgriffen wird, und daß beim Stecker zwischen Federkranz und Federzungen ein Führungsteil mit quadratischem Querschnitt vorgesehen ist, welches an seinen äußeren Rändern und Ecken Einschnitte aufweist, deren Konturen mit den Konturen der dem Stecker zugewandten Seite der benachbarten Kontaktmesser übereinstimmen. Auf diese Weise wird eine sichere Führung des Steckers vor seinem Einrasten bewirkt, so daß die nach außen gebogenen offenen Federzungen exakt an den Schirmpotential führenden benachbarten Kontaktmessern anliegen.An advantageous embodiment of the connection arrangement according to the invention is characterized in that the latching button has in its front area an outwardly directed circular bead which is encompassed by a spring collar located on the head of the plug, and that a guide part with a square cross section is located between the spring collar and spring tongues is provided, which has cuts on its outer edges and corners, the contours of which match the contours of the side of the adjacent contact blade facing the plug. This way it becomes a safe one Guidance of the plug before it snaps into effect, so that the outwardly bent open spring tongues lie exactly against the adjacent contact blades carrying the shield potential.
Eine weitere besonderes vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß innerhalb des Rastknopfes im Bereich des Durchbruchs eine Befestigungsscheibe eingebettet ist, die mit einem Durchbruch zum Durchstecken des Kontaktmessers versehen ist, und derart verdreht wird, daß Teile der inneren Kanten der Befestigungsscheiben in das Kontaktmesser und Teile der äußeren Kanten der Befestigungsscheiben in das Material des Rastknopfs einschneiden.A further particularly advantageous embodiment of the invention is characterized in that a fastening disk is embedded within the latching button in the area of the opening , which is provided with an opening for inserting the contact knife, and is rotated such that parts of the inner edges of the fastening disks cut into the contact knife and parts of the outer edges of the fastening disks into the material of the locking button.
Somit wird auf einfache Weise eine fest Verbindung zwischen signalführendem Kontaktmesser, Rastknopf und Rückwand-Verdrahtungsplatte hergestellt.Thus, a fixed connection between the signal-carrying contact knife, locking button and rear wall wiring plate is easily established.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Verbindungsanordnung ergeben sich aus den Unteransprüchen sowie der nachfolgenden Beschreibung eines Ausführungsbeispiels.Further advantageous configurations of the connection arrangement according to the invention result from the subclaims and the following description of an exemplary embodiment.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawing.

Die erfindungsgemaße Verbindungsanordnung besteht im wesentlichen aus dem noch näher zu beschreibenden Stecker, dem Rastknopf 6 und dem zur Verbindung gehörenden Kontaktmesser der Rückwand-Verdrahtungsplatte 9. Der Rastknopf 6 ist über das das elektrische Signal führende Kontaktmesser gestülpt und liegt auf der Rückwand-Verdrahtungsplatte 9 an. Die Befestigung des Rastknopfes 6 mittels der Befestigungsscheibe 7 wird später erläutert. Das jeweils das elektrische Signal führende Kontaktmesser ist von acht mit Schirmpotential verbundenen Kontaktmessern 8 umgeben.The connection arrangement according to the invention essentially consists of the plug to be described in more detail, the
Das ankommende Koax-Kabel 14 ist durch einen Koax-Stecker abgeschlossen. Der Koax-Stecker besteht aus dem Kunststoffgehäuse 1, der Druckhülse 3 und der Quetschhülse 4, sowie dem gefiederten Federkranz 2a mit den Federzungen 2b. Weiterhin befindet sich im Steckerinneren eine Kontaktfeder 5, die mit dem Innenleiter 10 des Koax-Kabels 14 fest kontaktiert ist. Mittels dieser Kontaktfeder 5 erfolgt der Kontakt mit dem das elektrische Signal führenden Kontaktmesser. Der Kabelgeflechtschirm 12 des Koax-Kabels 14 wird über eine Druckhülse 3 gestülpt, die vorher auf das Koax-Kabel 14 aufgestülpt worden ist. Dann wird von der Kabelseite her eine Quetschhülse über die Anordnung geschoben, so daß der Kabelgeflechtschirm 12 zwischen Druckhülse 3 und Quetschhülse 4 mit dem gefiederten Federkranz 2a fest kontaktiert wird. Die Montage und die Zugentlastung entspricht im wesentlichen den konstruktiven Lösungen der derzeit bekannten Koax-Stecker. Der Geflechtschirm 12 wird über die Quetschhülse 4 mit darunter liegendem gefiederten Federkranz 2a auf die Druckhülse 3 mit einer handelsüblichen Handzange gequetscht, wodurch die Zugentlastung für den Innenleiter realisiert wird. Zur größeren Sicherheit beim Ziehen des Steckers ist der gefiederten Federkranz 2a mit Krallen 11, die in das Kunststoffgehäuse 1 eingreifen, gesichert.The
Der gefiederte Federkranz 2a endet beim vorliegenden Ausführungsbeispiel in vier Federzungen 2b, die den Geflechtschirm 12 des Koax-Kabels 14 mit den Schirmpotential führenden benachbarten Kontaktmessern 8 verbinden.In the present exemplary embodiment, the feathered spring ring 2a ends in four
Am Ende des Steckers ist ein Federkranz 16 vorgesehen, der kreisförmig ausgebildet ist und um den Wulst 15 des Rastknopfes 6 greift und den Stecker so arretiert. Oberhalb des Federkranzes 16 in Richtung zum Kabel ist bei dem Stecker gemäß der vorliegenden Erfindung ein Führungsteil 22 vorgesehen. Dieses Führungsteil 22 weist einen quadratischen Umfang auf, wie besonders aus Figur 2 zu entnehmen ist. An den Seiten und an den Ecken dieses Führungsteils 22 sind Ausschnitte vorgesehen, die den benachbarten Kontaktmessern entsprechen. Auf diese Weise wird beim Stecken eine Zwangsführung des Steckers erreicht, womit sichergestellt wird, daß auch alle Federzungen 2b mit den Schirmpotential führenden Kontaktmessern 8 kontaktieren.At the end of the plug, a
Der Rastknopf 6 ist mittels einer Befestigungsscheibe 7 im aufliegenden Zustand auf der Rückwand-Verdrahtungsplatte 9 fest mit dem das elektrische Signal führenden Kontaktmesser verbunden. Bei der Befestigungsscheibe handelt es sich um eine Scheibe, wie sie in den Figuren 3 bis 5 dargestellt ist. Figur 3 zeigt eine Draufsicht, Figur 4 einen Querschnitt und Figur 5 einen Längsschnitt der Befestigungsscheibe 7. Die Außenabmessungen der Befestigungsscheibe 7 sind im wesentlichen rechteckförmig. Die längeren Außenkanten sind gerade ausgebildet und weisen jeweils in der Mitte Vorsprünge 20 auf. Die Vorsprünge 20 befinden sich im eingebauten Zustand der Befestigungsscheibe unter hier nicht näher dargestellten Prägungen, die die Scheibe nach dem Einlegen in den Rastknopf in ihrer Position halten. Die kürzeren Außenkanten der Befestigungsscheibe 7 sind kreisbogenförmig ausgebildet. Der Durchbruch 17 der Befestigungsscheibe 7 ist düsenförmig ausgebildet, was den Aufsteckvorgang auf das Kontaktmesser erleichtert. Die Abmessungen des Durchbruchs 17 entsprechen im wesentlichen dem Querschnitt des Kontaktmessers. Ein weiterer Vorteil des düsenförmig ausgebildeten Durchbruchs 17 ist, daß eine scharfe Innenkante entsteht. An zwei diagonal gegenüberliegenden Ecken der Befestigungsscheibe 7 sind Ausnehmungen 21 vorgesehen, in welche Zapfen eines Drehwerkzeugs zum Verdrehen der Befestigungsscheiben eingreifen können.The
Nach dem Aufstecken der mit den Befestigungsscheiben bestückten Rastknöpfe auf die Kontaktmesser wird die Befestigungsscheibe mittels eines Drehwerkzeugs verdreht. Wird ein Drehsinn im Uhrzeigersinn vorausgesetzt, so läßt sich der Figur 3 entnehmen, daß sich alle vier scharfen Innenkanten 18 in das Material des Kontaktmesser einschneiden, während die rechte obere und die linke untere Ecke der Befestigungsscheibe in das Material des Rastknopfs 6 einschneiden. Dieses Einschneiden in das Material des Rastknopfs 6 wird durch die kreisbogenförmige Ausbildung der kürzeren Außenkanten begünstigt. Nach dem Verdrehen der Befestigungsscheiben kommt es somit zu einer formschlüssigen Verankerung zwischen dem Kontaktmesser der Befestigungsscheibe und dem Rastknopf. Damit ist ein mehrmaliges sicheres Ziehen und Stecken des Steckers gewährleistet.After the snap buttons equipped with the fastening disks have been placed on the contact blades, the fastening disk is rotated using a turning tool. If a clockwise direction of rotation is assumed, it can be seen from FIG. 3 that all four sharp
Die in der Zeichnung dargestellte Steckverbindung hat eine Grundfläche von 5 x 5 mm bei einem Teilungsabstand der Kontaktmesser von 2,5 mm und ist auf der Rückwand-Verdrahtungsplatte ohne Teilungsverlust steckbar. Es lassen sich mit der erfindungsgemäßen Verbindungsanordnung Koax-Verbindungen mit der Rückwand-Verdrahtungsplatte verwirklichen, ohne diese zu durchlöchern und ohne zusätzliche Eingriffe in die Struktur der Rückwand-Verdrahtungsplatte. Dabei können bei der Verbindungsanordnung gemäß der vorliegenden Erfindung die Erdpunkte jeweils von zwei Steckern gemeinsam kontaktiert werden.The connector shown in the drawing has a base area of 5 x 5 mm with a pitch of the contact blades of 2.5 mm and can be plugged onto the rear wall wiring board without loss of pitch. With the connection arrangement according to the invention, coaxial connections can be realized with the rear wall wiring board without perforating it and without additional interventions in the structure of the rear wall wiring board. In this case, in the connection arrangement according to the present invention, the earth points can be contacted together by two plugs.
