Stand der TechnikState of the art
Die Erfindung geht aus von einer elektrischen Anschluß-Vorrichtung nach der Gattung des Hauptanspruchs. Die bekannten Anschluß-Vorrichtungen dieser Gattung sind zur Anbringung an den Kabelenden ausgebildet, sodaß ein beispielsweise als Ring- oder Sammelleitung dienendes Kabel in Einzelabschnitte aufgetrennt werden muß, wenn eine oder mehrere Leitungen an verschiedenen Stellen mit den Leitungsadern des Kabels kontaktiert werden sollen. Ferner ist es bekannt, Leitungen mittels Schneid-Klemm-Kontakten an ein durchlaufendes, einadriges, Kabel anzuschließen. Diese Lösung ist oft zu aufwendig und für den Anschluß an mehradrige Koaxialkabel mit einer die Leitungsadern umgebenden Abschirmung nicht geeignet.The invention is based on an electrical connection device according to the type of the main claim. The known connection devices of this type are designed to be attached to the cable ends, so that a cable serving, for example, as a ring or bus line must be split into individual sections if one or more lines are to be contacted at different points with the cable wires. It is also known to connect lines to a continuous, single-core cable using insulation displacement contacts. This solution is often too complex and not suitable for connection to multi-core coaxial cables with a shield surrounding the cable wires.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Anordnungen mit den kennzeichnenden Merkmalen der unabhängigen Ansprüche hat gegenüber der gattungsmäßigen Ausbildung von Anschluß-Vorrichtungen an ein- oder mehradrigen Kabeln den Vorteil, daß eine schnelle, gasdichte Kontaktierung ohne aufwendige Abisolierschritte an verschiedenen Stellen desThe arrangements according to the invention with the characterizing features of the independent claims have the advantage over the generic design of connection devices on single- or multi-core cables that a quick, gas-tight contact can be made without complex stripping steps at different points of the

durchlaufenden Kabels möglich ist. Der Abstand der Kontaktierungspunkte am Kabel ist frei wählbar und durch die fertigungsgerechte, einfache Verarbeitung ergibt sich ein beachtlicher Kostenvorteil gegenüber der bekannten Ausführung.continuous cable is possible. The distance between the contact points on the cable can be freely selected and the easy processing for production results in a considerable cost advantage compared to the known design.
Die anzuschließenden Leitungen können vorteilhaft mittels geeigneter Federelemente, z. B. mittels sogenannter Speed nuts, die einfach auf den Kabelmantel aufsteckbar sind, oder dergleichen, mit den freien Schenkelenden verbunden werden. Bei Anschlußvorrichtungen an Koaxialkabeln, deren Leitungsadern von einer Abschirmung umgeben sind, werden die Stifte oder Klammern vor dem Eintreiben in das Kabel an den die Abschirmung durchdringenden Bereichen ihrer Schenkel mit einem elektrisch isolierenden, abriebfesten Überzug versehen, der beispielsweise als Lackschicht oder als Keramikoxid-Schicht ausgebildet sein kann.The cables to be connected can advantageously be connected to the free leg ends using suitable spring elements, e.g. using so-called speed nuts, which can be easily plugged onto the cable sheath, or the like. In the case of connection devices on coaxial cables whose cable cores are surrounded by a shield, the pins or clamps are provided with an electrically insulating, abrasion-resistant coating on the areas of their legs that penetrate the shield before being driven into the cable. This coating can be designed, for example, as a layer of lacquer or a ceramic oxide layer.
Zeichnungdrawing
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Die einzige Figur zeigt einen Querschnitt durch ein schwachstromfuhrendes, zweiadriges Koaxialkabel mit einer Anschlußvorrichtung für zwei Signal- oder Steuerleitungen.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. The single figure shows a cross section through a low-current, two-wire coaxial cable with a connection device for two signal or control lines.
Beschreibung des AusführungsbeispielsDescription of the embodiment
Das Kabel hat zwei elektrische Leitungsadern 10, 12 mit rechteckigem Querschnitt, die in ein inneres Elektrikum 14 eingebettet sind. Dieses ist von einer Abschirmung 16 umgeben, die aus einem verzinktem Kupfergewebe besteht und außen von einer Schutzfolie 18 aus Polyester abgedeckt ist. Alle genannten Teile 10 - 18 sind von einem äußeren Kabelmantel 20 aus Polyuretan umschlossen.The cable has two electrical conductors 10, 12 with a rectangular cross-section, which are embedded in an inner electrical medium 14. This is surrounded by a shield 16, which consists of a galvanized copper mesh and is covered on the outside by a protective film 18 made of polyester. All of the parts 10 - 18 mentioned are enclosed by an outer cable sheath 20 made of polyurethane.

Das Kabel ist an dem dargestellten Querschnitt mit einer Anschluß-Vorrichtung versehen, die zwei radial aus dem Kabel austretende, je mit einer der Leitungsadern 10, 12 verbundene, gestreckte Kontakt-Elemente 22, 24 zum Anschluß der Signal- bzw. Steuerleitungen hat. Die Kontakt-Elemente 22, 24 sind durch die freien Enden von Schenkeln 26, 28 einer U-förmigen Klammer 30 gebildet, die radial so in das Kabel eingetrieben ist, daß die Schenkel 26, 28 die Leitungsädern 10, 12 durchdringen. An den mit den strichpunktierten Linien 32 gekennzeichneten, die Abschirmung durchdringenden Bereiche sind die Schenkel 26, 28 mit einem elektrisch isolierenden, abriebfesten Überzug, z. B. einer Lackschicht oder einer Keramikoxid-Schicht versehen, der einen metallischen Kontakt mit der Abschirmung 16 vermeidet.The cable is provided with a connection device in the cross-section shown, which has two elongated contact elements 22, 24 for connecting the signal or control lines, each of which emerges radially from the cable and is connected to one of the conductor wires 10, 12. The contact elements 22, 24 are formed by the free ends of legs 26, 28 of a U-shaped clamp 30, which is driven radially into the cable in such a way that the legs 26, 28 penetrate the conductor wires 10, 12. In the areas marked with the dot-dash lines 32 that penetrate the shield, the legs 26, 28 are provided with an electrically insulating, abrasion-resistant coating, e.g. a layer of varnish or a ceramic oxide layer, which prevents metallic contact with the shield 16.
Die Klammer 30 ist so weit in das Kabel eingetrieben, daß ihr Steg 34 am Kabelmantel 32 anliegt. Danach ist der Steg 34 durch einen Trennschlitz 36 geteilt, der eine für die elektrische Isolierung ausreichende Breite B aufweist. Auf diese Weise ist jedes der beiden Kontakt-Elemente 22, 24 für sich mit einer der beiden Leitungsadern 10 bzw. 12 verbunden und gasdicht aus dem Kabelmantel 20 herausgeführt. Die weiterführenden Leitungen können über bekannte Verbindungselemente, wie Speed nuts und dergleichen, an die Kontakt-Elemente 22, 24 angeschlossen werden.The clamp 30 is driven into the cable so far that its web 34 rests against the cable sheath 32. The web 34 is then divided by a separating slot 36, which has a width B sufficient for electrical insulation. In this way, each of the two contact elements 22, 24 is connected to one of the two cable wires 10 or 12 and is led out of the cable sheath 20 in a gas-tight manner. The further cables can be connected to the contact elements 22, 24 using known connecting elements, such as speed nuts and the like.
Bei einem einadrigen Kabel wird statt der U-förmigen Klammer 30 ein einzelner Stift mit einem Schenkel 26 in das Kabel eingetrieben. Der Stift kann einseitig einen Kopf oder ein abgewinkeltes Ende aufweisen. Diese Ausführung entspricht dann der in der Figur gezeigten, wobei eine Leitungsader 12 und ein Schenkel 28 fehlt.In the case of a single-core cable, a single pin with a leg 26 is driven into the cable instead of the U-shaped clamp 30. The pin can have a head or an angled end on one side. This design then corresponds to the one shown in the figure, with a cable core 12 and a leg 28 missing.
Bei mehradrigen Kabeln können einzelne oder alle Leitungsadern 10, 12 kontaktiert werden, indem einzelne Stifte, U-förmig Klammern oder Klammern mit mehreren Schenkeln eingetrieben werden.In the case of multi-core cables, individual or all of the conductor cores 10, 12 can be contacted by driving in individual pins, U-shaped clamps or clamps with multiple legs.
