Abstract

The overall sleeve is for cables a metal support cladding. The sleeve is provided with coupling arrangements at its ends, the design being intended to simplify fitting whilst maintaining the required degree of sealing. The sheath, which may provide protection for the junction of several cables with a single one uses a shrink-on end sleeves. Between the shrink-on layer and its mating surface is a layer of glue or some similar material assisting the seal. A pressure relief valve is included at the elbow created by the entry of the single cable into the junction. The sleve junction at this same end is maintained by interlocking rims of the sleeve and inside surface.

Kabelmuffen dieser Art weisen eine Reihe von Vorteilen auf, insbesondere den der einfachen Herstellung, d.h.Cable sleeves of this type have a number of advantages, in particular that of simple manufacture, i.e.

ohne die Notwendigkeit eines größeren apparativen Aufwandes.without the need for a large outlay in terms of equipment.

Nun hat es sich allerdings noch gezeigt, daß beim Anschuß von Kabeln mit Gasdrucküberwachung ein Ablösen infolge des Gasuberwachungsdruckem Inneren der Muffe zwischen Kabel und Kabeleingang der Nuffenköpfe eintreten kann, was, wenn einmal der Beginn der Ablösung gemacht ist, zu einem weiteren langsamen Abschälen des Kabeleingangs und damit schließlich zur Undichtigkeit der betreffenden Muffe führen kann.However, it has now been shown that when cables are connected with gas pressure monitoring a detachment as a result of the gas monitoring pressure inside the Sleeve between cable and cable entry of the socket heads can occur, what if once the start of peeling is done, to another slow peeling of the cable entry and thus ultimately to the leakage of the joint in question can lead.

Aufgabe der Erfindung ist die Schaffung einer Lösung, welche eine derartige vorbeschriebene Schälwirkung bei Muffen mit im Inneren derselben herrschendem Gasüberwachungsdruck mit Sicherheit vermeidet.The object of the invention is to provide a solution which is a such above-described peeling action in sleeves with inside the same prevailing Avoid gas monitoring pressure with certainty.

Bei einer Kabelmuffe der eingangs bezeichneten Art wird diese Aufgabe gemaß der Erfindung dadurch gelöst, daß Jeder Kabeleingang Jedes Muffenkopfes mit einer dem einmündenden Kabel anliegenden, einwärts zur Muffe gerichteten, einstückig mit dem betreffenden Kabeleingang ausgebildeten, manschettenförmigen Verlängerung versehen ist.In the case of a cable sleeve of the type described at the outset, this task becomes solved according to the invention in that each cable entry each sleeve head with one of the leading cables, inwardly directed towards the sleeve, in one piece with the relevant cable entry trained, cuff-shaped extension is provided.

Aufgrund dieser Ausbildung wird erreicht, daß der Druck beidseits dieser manschettenförmigen Verlängerung sich mindestens ausgleicht, wenn nicht ein Drucküberschuß auf der dem Kabelmantel abgelegenen Seite der Verlängerung vorhanden ist, welcher die Verlängerung gegen das Kabel drückt, so daß ein Ablöseprozeß ausgeschlossen ist.Because of this training it is achieved that the pressure is on both sides this cuff-shaped extension at least compensates, if not one Excess pressure on the side of the extension remote from the cable jacket which presses the extension against the cable, so that a detachment process is excluded is.

Eine weiter verbesserte Sicherung kann man dadurch erhalten, wenn man am freien Rand der manschettenförmigen Verlängerung eine Schelle zur festen Anlage der Verlängerung gegen das Kabel vorsieht.A further improved security can be obtained if a clamp on the free edge of the cuff-shaped extension to the fixed Provides for the extension against the cable.

Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert. Diese zeigt einen Teillängsschnitt durch eine Kabelmuffe gemäß der Erfindung mit einem Muffenkopf mit einem Kabeleingang.The invention is illustrated below with reference to the drawing, for example explained in more detail. This shows a partial longitudinal section through a cable sleeve according to FIG of the invention with a socket head with a cable entry.

Wie beim Gegenstand des Hauptpatentes besteht die in der Zeichnung wiedergegebene Kabelmuffe im wesentlichen aus zwei metallischen halbzylindrischen Stützmantelteilen 1 mit einwärts gerichteten Bördelrändern 2, die hinter nach außen gerichtete Bördelränder 3 von metallischen Stützringen 4 greifen, welch letztere sich in den Verbindungsrand lla eines Muffenkopfes 5a mit einem Kabeleingang 6a erstrecken. Über die Stützmantelteile 1 und den Verbindungsrand lla des Muffenkopfes 5a erstreckt sich ein Kunststoff-Schrumpfschlauch 13.As with the subject of the main patent, there is one in the drawing The cable sleeve shown consists essentially of two metallic semi-cylindrical ones Support jacket parts 1 with inwardly directed flanged edges 2, the rear to the outside directed beaded edges 3 grip metallic support rings 4, which latter into the connecting edge 11a of a socket head 5a with a cable entry 6a extend. About the support jacket parts 1 and the connecting edge 11a of the socket head 5a a plastic shrink tube 13 extends.

Im Inneren des Kabeleingangs 6a ist eine Klebeschicht 14 und im Inneren des Endes des Schrumpfschlauches 13 ist eine Klebeschicht 15 aus einem Kleber angebracht, der beim Erreichen der Schrumpftemperatur für die Kabeleingänge und den umhüllenden Schrumpfschlauch flüssig wird.In the interior of the cable entry 6a is an adhesive layer 14 and in the interior an adhesive layer 15 made of an adhesive is attached to the end of the shrink tube 13, when the shrinking temperature is reached for the cable entries and the enveloping Shrink tubing becomes liquid.

Gemäß der Erfindung ist nun der Kabeleingang 6a des Muffenkopfes 5a mit einer einwärts gerichteten manschettenartigen Verlängerung 16 versehen, die dem Kabel K eng anliegt und durch eine anziehbare Schelle 17 zusätzlich fest gegen den Kabelmantel zur Anlage gebracht wird.According to the invention, the cable entry 6a of the socket head 5a is now provided with an inwardly directed cuff-like extension 16 which the cable K rests tightly and additionally firmly against it by means of a tightenable clamp 17 the cable sheath is brought to bear.

Wie erkennbar ist, kann aufgrund dieser Ausbildung auch bei stärkerem Gasdruck innerhalb der fertigen Muffe ein Ablösen bzw. Abschälen des Kabeleingangs des Muffenkopfes von dessen Innenrand her und damit ein IJndichtwerden der Muffe mit Sicherheit nicht mehr eintreten.As can be seen, this training can also be used for stronger Gas pressure within the finished sleeve causes the cable entry to become detached or peeled off of the socket head from its inner edge and thus a leakage of the socket certainly not happen again.
