Description
neschreibung:Description:
Zugfeste und feuchtigkeitsdichte Vertappunz von Lichtwellenleiter-
Sollen Kabel insbesondere Lichtwellenleiterkabel, deren Übertragungselemente nicht für eine Zugbelastung geeignet sind, in einen Kabelkanal mittels eines Ziehseils eingezogen werden, ist eine zuverlässige Verbindung zwischen Zugseil und dem Kabelanfang erforderlichO Zu diesem Zweck hat man man am Ende von Lichtwellenleiter-Kabeln und Koaxialkabeln Verkappungen mit Gießharzfüllung eingesetzt, wobei durch die Gießharzfüllung die Ubertragungselemente kraftschlüssig mit dem Kabelmantel verbunden sind, so daß die auf Verkappung ausgeübten Zugkräfte auf die Ubertragungselemente übertragen werden0 Die Kabel werden mit außen an denselben angebrachten Ziehstrümpfen gezogen und teilweise geschoben.Should cables especially fiber optic cables, their transmission elements are not suitable for a tensile load, in a cable duct by means of a pull rope be pulled in, is a reliable connection between the pull rope and the beginning of the cable requiredO For this purpose one has at the end of fiber optic cables and Coaxial cable caps with cast resin filling used, whereby through the cast resin filling the transmission elements are positively connected to the cable jacket, so that transmit the tensile forces exerted on the cap to the transmission elements werden0 The cables are pulled with pulling stockings attached to the outside of the same and partially pushed.
Die der Erfindung zugrunde liegende Aufgabe besteht nun darin, eine zugfeste und feuchtigkeitsdichte Verkappung für Lichtwellenleiterkabel und Spezialkabel zu schaffen die gleichermaßen als Lager=, Strecken- und Werksverkappung, also Einheitsverkappung universell eingesetzt werden kann. Dabei soll der Materialaufwand gering sein die Montage und die Kabelverlegung mit gebräuchlichem Werkzeug sicher und schnell erfolgen können. Gießharze sollen nicht verwendet werden, damit eine mugbelastuag der Übertragungselemente vermieden wird und die Verkappung unmittelbar nach Herstellung einsatzbereit ist0 Die Verkappung zum Verbinden eines Lichtwellenleiterkabels oder Koaxialkabels mit einem nugsel der eingangs beschriebenen Art ist erfindungsgemäß dadurch gekennzeichnet, daß vor Beginn der Montage des " Preß - Zugankers " auf das Kabelende ein kurzes Stück vom Kabel ende her der Kabelmantel - ohne die im mantel eingebetteten flexiblen Zugelemente (7) - und alle Ubertragungselemente (11) entfernt werden, damit nur die Zugelemente (6) und oder (7 frei liegen0 Hierüber wird zunächst der hintere Kegelstumpf (2) und der in der Mitte angeordnete Preßkörper (4) vom Kabelende her zentrisch und axial bis an die Kabelseele t10) aufgeschoben, bei flexiblen Zugelementen g7) werden zusätzlich die zugelemente t7) zurück über den rreßkonus t5) in Richtung Kabel gelegt, vorzugsweise wird in das Gewinde des hinteren Kegelstumpfs t2) luetallkleber aufgetragen. mit einem Schraubenschlüssel wird der hintere Kegelstumpf (2) festgehalten und mit einem durch die Bohrung des -Ziehkopfs (1) solange gedreht, bis der in gewissen Grenzen bewegliche Preßkörper (4) mit hohem Preßdruck gegen die Zugelemente (6) und (7) gedrückt hat. Anschließend wird nach dem Aufschrumpfen eines schmel zkleberbeschi chteten Schrumpfschlauches (8) der Spalt zwischen Ziehkopf (1) und Kabelmantel (9) abgedichtet.The object of the invention is now to provide a Tensile and moisture-proof encapsulation for fiber optic cables and special cables to create the same as warehouse, line and factory capping, i.e. unit capping can be used universally. The cost of materials should be low Assembly and cable routing can be carried out quickly and safely with common tools can. Casting resins should not be used, so that a mugladenuag of the transmission elements is avoided and the capping is ready for use immediately after manufacture0 The capping for connecting a fiber optic cable or coaxial cable with a nugsel of the type described above is characterized according to the invention, that before starting the assembly of the "press-tie rod" on the cable end a short one Piece from the cable end of the cable sheath - without the flexible embedded in the sheath Tension elements (7) - and all transmission elements (11) are removed so that only the tension elements (6) and or (7 are exposed) Truncated cone (2) and the pressed body (4) arranged in the middle from the end of the cable centrically and axially pushed up to the cable core t10), with flexible tension elements g7), the tightening elements t7) are also moved back over the rupture cone t5) in the direction of Cable is laid, preferably in the thread of the rear truncated cone t2) metallic glue applied. the rear truncated cone (2) is held in place with a wrench and with a through the hole of the pulling head (1) rotated until the in certain Limits movable pressing body (4) with high pressure against the Has pressed tension elements (6) and (7). Then after shrinking on one Melt-adhesive-coated shrink tubing (8) the gap between the pulling head (1) and cable jacket (9) sealed.
Die Erfindung wird im folgenden anhand eines in den Fig. 1 und 2 dargestellten Ausführungsbeispieles näher erläutert.The invention is illustrated below with reference to one in FIGS Embodiment explained in more detail.
Fig. 1 zeigt die Anordnung eines fertig montierten Preß-Zugankers.Fig. 1 shows the arrangement of a fully assembled press tie rod.
Der Preß-Zuganker besitzt an seinem hinteren Teil einen Kegelstumpf mit Außengewinde (2) und einen Zweikant (3), in seinem mittleren Bereich Preßschalen (4) und in seinem vorderen Bereich einen Ziehkopf mit Kegelstumpf und Innengewinde (1). Durch Drehen am Ziehkopf (1) und festhalten des hinteren Kegelstumpfes (2) werden die Preßschalen (4) mit hohem Preßdruck gegen das innenliegende massive Zugelement (6) gepreßt. Über das so ausgebildete Kabelende wird ein Schrumpfschlauch (8) geschoben, durch Wärmezufuhr wird eine dichte Werbindung von Ziehkopf (1) und Kabelmantel (9)hergestellt.The press tie rod has a truncated cone on its rear part with external thread (2) and a two-edge (3), in its central area compression shells (4) and in its front area a pulling head with a truncated cone and internal thread (1). By turning the pulling head (1) and holding the rear truncated cone (2) the pressing shells (4) with high pressure against the internal massive tension element (6) pressed. A shrink tube (8) is pushed over the cable end formed in this way, By supplying heat, a tight binding is created between the pulling head (1) and the cable sheath (9).
Fig.2 zeigt abweichend zu Fig. 1, daß die Zugelemente (7) flexibel sind und über den Preßkonus (5) zurück in Richtung Kabel gebogen sind0In contrast to FIG. 1, FIG. 2 shows that the tension elements (7) are flexible and are bent over the press cone (5) back towards the cable0
