Abstract

The tension-resistant and moisture-proof capping of an optical waveguide cable, coaxial cable or power cable has a casting-resin tie rod in which the tensile load members anchored in casting resin are anchored as barbs. The casting-resin tie rod has on its rear part a cable guide (15) with external thread, and in its front part a drawing head with internal thread (12) or (14). A shrink-on tube (8) is arranged over the casting-resin tie rod (12) or (14) and the cable jacket (9). <IMAGE>

Description

beschreibung description

Gießharz - Zuganker Die Wrtindung betrifft eine zugfeste und feuchtigkeitsdichte Verkappung von Kabeln deren Elemente ein Eintreiben eines Zugdornes in die abelseele nicht erlaubt (um diese am Zug beteiligen zu können), insbesondere Xichtwellenleiterkabel, Koaxialkabel, Starkstromkabel, bestehend aus einer über die Zugelemente und Kabelmantel aufgeschobenen Kabelführung mit Außengewinde, aus einem biehkop! mit Innengewinde der nach ießharzfüllung auf die Labelführung aufgeschraubt den zugfesten verbund zum Kabel herstellt, und aus einem als dichten Abschluß des Kabels und des Ziehkopfes aufgeschrumpften, wärmeschrumpfenden Schrumpfschlauches Sollen Kapsel mit geringem Durchmesser oder Kabel deren Kabelseele ein Eintreiben eines Zugankers in die Kabelseele nicht erlaubt, insbesondere Lichtwellenleiterkabel oder Koaxialkabel in einen Kabelkanal mittels eines Ziehseils eingezogen werden, ist eine zuverlässige Verbindung zwischen Zugseil und dem Kabelanfang erforderlich.Cast resin - tie rod The term concerns a tensile strength and moisture-proof Capping of cables, the elements of which involve driving a pull rod into the cable core not allowed (in order to be able to involve them in the train), especially non-waveguide cables, Coaxial cable, power cable, consisting of one over the tension elements and cable sheath pushed-on cable guide with external thread, from a biehkop! with internal thread which is screwed onto the label guide after the resin has been filled with the high tensile strength to the cable, and from one as a tight seal of the cable and the pulling head Shrink-fit, heat-shrinkable tubing should be capsule with low Diameter or cable with a cable core driving a tie rod into the cable core not allowed, especially fiber optic cables or coaxial cables in a cable duct be pulled in by means of a pull rope is a reliable connection between Pull rope and the beginning of the cable required.

Zu diesem Zweck hat man am sunde von Lichtwellenleiterkabeln und Koaxialkabeln Gießharzverkappungen angebracht. Die Kabel werden mit außen an denselben angebrachten Ziehstrümpfen gezogen, daher müssen die Verkappungen hauptsächlich sicherstellen, daß die Zugkraft nicht ausschließlich über den Kabelmantel, sondern im gleichen Maße auch über die Zugelemente oder Kabelseele übertragen wird, damit keine Xelativbewegung zwischen Kabelseele und Kabelmantel auftritt.For this purpose, fiber optic cables and coaxial cables are popular Cast resin caps attached. The cables are attached to the outside of the same Pulling stockings pulled, so the capping must mainly ensure that the tensile force is not exclusively through the cable jacket, but in the same way Dimensions are also transferred via the tension elements or cable core so that no relative movement is possible occurs between the cable core and the cable sheath.

Eine derartige Verkappung geht beispielsweise aus der DE 2509474 hervor.Such a capping emerges from DE 2509474, for example.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, eine zugfeste und feuchtigkeitsdichte Verkappung für Lichtwellenleiterkabel, Koaxialkabel, Starkstromkabel und Spezialkabel zu schaffen, die gleichermaßen als Lager - und Werksverkappung universell eingesetzt werden kann. Dabei soll, insbesondere bei Lichtwellenleiterkabeln, die Zugbelastung nur über die Zugelemente erfolgen.The object of the invention is to provide a tensile strength and moisture-proof encapsulation for fiber optic cables, coaxial cables, power cables and to create special cables that can be used both as warehouse and factory encapsulation can be used universally. In doing so, especially in the case of fiber optic cables, the tensile load is only carried out via the tension elements.

Die Verkappung zum Verbinden eines Lichtwellenleiterkabels oder Koaxialkabels mit einem Zugseil der eingangs beschriebenen Art ist erfindungsgemäß d a d u r c h g e k e n n z e i c 11 n e t, daß vor beginn der montage des Gießharz - Zugankers auf das Kabelende ein kurzes Stück vom Kabelende her der Kabelmantel und evtl. Isolierungen entfernt werden, damit die Kabelführung (15) vom Kabelende her zentrisch und axial über die Zugelemente (6) oder (13) bis über den Kabelmantel (9) aufgeschoben und die Zugelemente (6) oder (13) für die Gießharzverankerung präpariert werden kann. Nach Gießharzfüllung (16) des Ziehkopfes mit Innengewinde (12) oder (14) wird der Ziehkopf (12) oder (14) auf die Kabelführung (15) aufgeschraubt, der Verschluß senkrecht auf eine Unterlage gestellt und gegebenenfalls von der Kabelführung (15) aus, der Verschluß vollständig mit Gießharz (16) aufgefüllt0 Anschließend wird nach dem Aufschrumpfen eines schmelzkleberbeschichteten Schrumpfschlauches (8) der Spalt zwischen Ziehkopf (12) oder (14) und Kabelmantel (9) abgedichtet.The capping for connecting a fiber optic cable or coaxial cable with a pull rope of the type described above, according to the invention, d a d u r c h e k e n n e i c 11 n e t that before starting the assembly of the cast resin tie rod on the end of the cable a short distance from the end of the cable, the cable sheath and any insulation be removed so that the cable guide (15) is centered and axial from the cable end pushed over the tension elements (6) or (13) to over the cable jacket (9) and the tension elements (6) or (13) prepared for the cast resin anchoring will can. After the cast resin filling (16) the pulling head with internal thread (12) or (14) is the pulling head (12) or (14) screwed onto the cable guide (15), the lock placed vertically on a base and, if necessary, removed from the cable guide (15) off, the cap is completely filled with casting resin (16) the shrinking on of a hot-melt adhesive-coated shrink tube (8), the gap sealed between pulling head (12) or (14) and cable jacket (9).

Die Erfindung wird im folgenden anhand eines in den Fig. 1 bis 3 dargestellten ÅusführungsbeisDieles näher erläutert.The invention is illustrated below with reference to one in FIGS The execution example is explained in more detail.

Fig. 1 zeigt die Anordnung eines fertig montierten Gießharz -Zugankers für Lichtwellenleiterkabel.Fig. 1 shows the arrangement of a fully assembled cast resin tie rod for fiber optic cables.

Der Gießharz - Zuganker besitzt an seinem hinteren Teil eine Kabelführung (15)- mit Außengewinde, in seinem mittleren Bereich das im Gießharz (16) vergossene Zugelement (6) und in seinem vorderen Bereich einen auf die Kabelführung (15) aurgeschraubten Ziehkopf mit Innengewinde (12).The cast resin tie rod has a cable guide on its rear part (15) - with an external thread, in its central area the one encapsulated in the cast resin (16) Tension element (6) and in its front area one screwed onto the cable guide (15) Pulling head with internal thread (12).

Leber das so ausgebildete Kabelende wird ein Schrumpfschlauch (8) geschoben, durch Wärmezufuhr wird eine dichte verbindung von Ziehkopf (12) und Kabelmantel (9) herstellt.Liver the cable end formed in this way becomes a shrink tube (8) pushed, the heat supply creates a tight connection between the pulling head (12) and the cable sheath (9) manufactures.
