Abstract

In the case of the device, two essentially identical conical sleeves which can be pushed over one another are threaded onto at least one strain-relief layer. That end section of the strain-relief layer which is to be fixed is wrapped around the outer surface of the first sleeve, which is arranged closer to the fibre end, and the second sleeve is pushed over the fibres, which are distributed on the outer surface, of the strain-relief layer such that the fibres are clamped in between the two sleeves. It is furthermore provided for that end surface of the second sleeve which points towards the cable to be supported such that, in the event of a tension load, the two sleeves are pushed even more firmly into one another, and the strain-relief layer is in consequence clamped in even more firmly.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Fixieren von wenigstens einer faserförmigen Zugentlastungsschicht an wenigstens einem Kabelende, beispielsweise einem Lichtwellenleiterkabel.The invention relates to a device for fixing at least one fibrous strain relief layer on at least a cable end, for example an optical fiber cable.

Eine solche Vorrichtung ist beispielsweise aus der US-PS 41 14 979 bekannt.Such a device is for example from US-PS 41 14th 979 known.

Ein Nachteil dieser bekannten Lösung besteht darin, daß sie im wesentlichen irreversibel ist.A disadvantage of this known solution is that it is essentially irreversible.

Es hat sich nämlich gezeigt, daß es unter Umständen notwendig sein kann, die Verbindung zwischen Kabel und beispielsweise einem Steckergehäuse wieder zu lösen.It has been shown that it may be necessary can be the connection between cables and for example to detach a connector housing.

Aufgabe der Erfindung ist daher, eine Vorrichtung nach dem Obergriff zu schaffen, die es möglich macht, eine solche Ver­ bindung beliebig lösbar zu gestalten.The object of the invention is therefore a device according to To create a grip that makes it possible to create such a ver to make the binding detachable.

Bei der Vorrichtung der eingangs genannten Gattung wird diese Aufgabe erfindungsgemäß durch die Merkmale des kennzeichnenden Teils in Anspruch 1 gelöst.In the device of the type mentioned at the beginning, this is Task according to the invention by the features of the characteristic Partly solved in claim 1.

Vorteilhafte weitere Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous further embodiments of the invention are in the Subclaims specified.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand von zwei Figuren näher erläutert. An embodiment of the invention is described below explained in more detail by two figures.  

Es zeigen:Show it:

Fig. 1 zwei kegelige, auf ein Kabel gefädelte Hülsen in geschnittener Ansicht und Fig. 1 two conical sleeves threaded on a cable in a sectional view and

Fig. 2 die beiden kegeligen Hülsen übereinandergeschoben in ein Steckergehäuse eingesetzt. Fig. 2 inserted the two tapered sleeves one over the other in a connector housing.

Wie aus Fig. 1 ersichtlich, sind zwei kegelige Hülsen 1, 2 vorgesehen, die mit der konisch verjüngten Seite voraus so auf einen vom Kabelmantel 4 freigelegten Endabschnitt 3 eines Kabels 10 aufgeschoben sind, daß sie zunächst mit einem gewissen Abstand voneinander hintereinander auf dem Kabel 10 sitzen. Der Endabschnitt 3 einer aus zahlreichen Fasern bestehenden Zug­ entlastungsschicht 11 ist im wesentlichen gleichmäßig um die in Aufschieberichtung hintere Hülse 1 verteilt und soweit nach hin­ ten umgelegt, daß der faserförmige Endabschnitt 3 die Außen­ fläche 6 der Hülse 1 überdeckt. Nach Verschieben der anderen Hülse 2 entgegen der Aufschieberichtung (in Pfeilrichtung) sitzt der Endabschnitt 3 eingeklemmt zwischen Hülse 1 und Hülse 2. Die Klemmwirkung kann noch verbessert werden, wenn man zumindest die Innenfläche 5 oder Außenfläche 6 mit einer rauhen, also reibungs­ erhöhenden Struktur versieht.As can be seen from Fig. 1, two tapered sleeves 1 , 2 are provided, which are pushed with the conically tapered side in advance onto an exposed from the cable sheath 4 end portion 3 of a cable 10 that they are initially at a certain distance from each other on the cable 10 sit. The end portion 3 of a train consisting of numerous fibers relief layer 11 is distributed substantially uniformly around the rear sleeve 1 in the push-on direction and as far as folded down that the fibrous end portion 3 covers the outer surface 6 of the sleeve 1 . After moving the other sleeve 2 against the push-on direction (in the direction of the arrow), the end section 3 is clamped between the sleeve 1 and sleeve 2 . The clamping effect can be further improved if at least the inner surface 5 or outer surface 6 is provided with a rough, that is to say friction-increasing, structure.

Aus Fig. 2 ist zu entnehmen, daß die bereits übereinander ge­ schobenen Hülsen 1 und 2 mit dem zwischen ihnen eingeklemmten Endabschnitt 3 quer zur Verlaufsrichtung des Kabels 10 so in ein Steckergehäuse 9 eingelegt sind, daß eine dem Kabel 10 zuge­ wandte Stirnfläche 7 der Hülse 2 an einer Anlagefläche 8 im Steckergehäuse 9 anliegt. Wird die Zugentlastungsschicht 11 in Pfeilrichtung belastet, dann werden dadurch die Hülsen 1 und 2 weiter ineinandergeschoben, wodurch die Klemmwirkung der Hülsen 1, 2 verstärkt und der zwischen den Hülsen 1, 2 festsitzende Endabschnitt 3 noch mehr fixiert wird.From Fig. 2 it can be seen that the sleeves 1 and 2 already pushed one above the other with the end portion 3 clamped between them are inserted transversely to the direction of the cable 10 in a plug housing 9 that a cable 10 facing end face 7 of the sleeve 2 bears against a contact surface 8 in the connector housing 9 . If the strain relief layer 11 is loaded in the direction of the arrow, then the sleeves 1 and 2 are pushed further into one another, as a result of which the clamping action of the sleeves 1 , 2 is strengthened and the end section 3 which is stuck between the sleeves 1 , 2 is fixed even more.
