Abstract

The carrier (10), provided with a groove (11), has in the area of the groove flange (13) a slightly larger diameter than in its other areas. In this way, the rotatable spring ring (15) can rest in one position with its end (16) on this groove flange, as a result of which the locking pressure on the optical waveguide (20) is cancelled so that it can be positioned. With a small rotation of the spring ring in the direction of the arrow (17) the optical waveguide (20) can be locked again immediately. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Lichtwellenleiter- Verbinder, bei dem die zu verbindenden Lichtwellenleiter in einem mit einer Nut versehenen etwa zylindrischen Träger geführt und mit Hilfe von offenen Federringen, die den zylindrischen Träger annähernd umschließen, fixiert werden.The invention relates to an optical waveguide. Connector in which the optical fibers to be connected in an approximately cylindrical carrier provided with a groove guided and with the help of open spring washers that the approximately enclose the cylindrical support, be fixed.

Ein Lichtwellenleiter-Verbinder dieser Art wird u. a. in der DE-OS 27 37 114 beschrieben. Dabei werden zum Fixieren der zu verbindenden Lichtwellenleiter Federringe verwendet, die drehbar auf dem zylindrischen Träger angeordnet sind.An optical fiber connector of this type is u. a. in the DE-OS 27 37 114 described. Doing so will fix the connecting fiber optic spring washers used are rotatably arranged on the cylindrical support.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Art der Fixierung so auszubilden, daß die Manipulation der Lichtwellen­ leiter zum Justieren weiter vereinfacht wird. Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß der Träger im Bereich der Nut derart unsymmetrisch ausgebildet ist, daß der Träger an der Stelle einer Nutflanke einen etwas größeren Durchmesser als in den anderen Bereichen aufweist.The invention has for its object the known type of Fixation so that the manipulation of light waves head for adjustment is further simplified. To solve this Object is proposed according to the invention that the carrier is so asymmetrical in the region of the groove that the carrier has a slightly larger one at the location of a groove flank Has diameter than in the other areas.

Auf diese Weise gelingt es, mit Hilfe eines solchen drehbar angeordneten Federringes mit einer ganz einfachen Manipulation einen Lichtwellenleiter entweder zu fixieren oder ihn zu ent­ arretieren, so daß die exakte Positionierung eines Licht­ wellenleiters mit ganz geringem Aufwand durchführbar ist.In this way it is possible to rotate with the help of such arranged spring ring with a very simple manipulation either fix an optical fiber or remove it lock so that the exact positioning of a light waveguide can be carried out with very little effort.

Die Erfindung wird anhand des nachfolgend beschriebenen und in der Zeichnung dargestellten Ausführungsbeispieles im einzelnen erläutert. In der Zeichnung zeigt:The invention is described in the following and in the drawing shown embodiment in detail explained. The drawing shows:

Fig. 1 einen Querschnitt durch einen zylindrischen Träger einschließlich eines drehbaren Federringes und Fig. 1 shows a cross section through a cylindrical support including a rotatable spring ring and

Fig. 2 den gleichen Querschnitt mit einer anderen Position des Federringes. Fig. 2 shows the same cross section with a different position of the spring ring.

Der in Fig. 1 im Querschnitt dargestellte Träger 10 ist mit einer Nut 11 versehen, deren beide Nutflanken 12 und 13 dadurch unsymmetrisch ausgebildet sind, daß die Nutflanke 13 eine wesentlich größere Länge als die andere Nutflanke aufweist, d. h. der Träger besitzt an der Stelle der Nutflanke 13 einen größeren Durchmesser als im Bereich der anderen Nutflanke. Dadurch kann der auf dem Träger 10 drehbar angeordnete geschlitzte Federring 15 in der in Fig. 1 dargestellten Lage mit seinem einen Ende 16 den in der Nut 11 zu fixierenden Lichtwellenleiter 20, wie dargestellt, arretieren. Wird der Federring 15 in die in Fig. 2 dargestellte Position gedreht, liegt das eine Ende 16 jetzt auf der höheren Nutflanke 13 auf, wodurch der Druck auf den Lichtwellenleiter aufgehoben wird, so daß dieser frei in der Nut hin- und hergeschoben werden kann. Nach vollendeter Justage kann durch einfache Verdrehung des Federringes die Fixierung des Lichtwellenleiters in der Nut wiederhergestellt werden.The carrier 10 shown in cross section in FIG. 1 is provided with a groove 11 , the two groove flanks 12 and 13 of which are formed asymmetrically in that the groove flank 13 has a substantially greater length than the other groove flank, ie the carrier has at the point of Groove flank 13 has a larger diameter than in the area of the other groove flank. As a result, the slotted spring ring 15 rotatably arranged on the carrier 10 can, in the position shown in FIG. 1, lock the one end 16 of the optical waveguide 20 to be fixed in the groove 11 , as shown. If the spring ring 15 is rotated into the position shown in FIG. 2, the one end 16 now lies on the higher groove flank 13 , as a result of which the pressure on the optical waveguide is released so that it can be freely pushed back and forth in the groove. After the adjustment has been completed, the optical fiber can be fixed in the groove by simply turning the spring ring.
