Abstract

The invention relates to a device for deflecting an optical waveguide (8, 9) or optical waveguide cable, comprising a grommet whose base in the longitudinal direction has a radius of curvature (R10) which is greater than the minimum bending radius of optical waveguides . To ensure that the device can be used universally it comprises four grommets (a, b, c, d) whose curvatures in the longitudinal direction are situated in the same plane (plane of drawing) and positioned opposite each other in pairs so that one pair of grommets (a-c) opens directly into an opposite pair of grommets (b-d).

Beschreibung des AusführungsbeispielsDescription of the embodiment
An einem Gestellholm 1, der eine Seitenwand 7 trägt, ist mit Hilfe einer Schraube 2 eine Einrichtung nach der Erfindung befestigt. Diese weist ein zweifach abgewinkeltes Halteblech 3 auf, das vier Tüllen a, b, c, d trägt, deren gekrümmte Längsrichtungen in der gemeinsamen Zeichenebene der Figur 2 liegen und die einander paarweise gegenüberliegen. Alle vier Tüllen münden in einen gemeinsamen, zentralen Hohlraum 4. Sie werden von zwei Schellen 5 beziehungsweise 6 zusammengehalten, die an dem Halteblech 3 befestigt sind. Bezüglich zweier senkrecht zur Zeichenebene verlaufender Symmetrieebenen - einer waagerechten und einer senkrechten - sind die Tüllen spiegelsymmetrisch zueinander angeordnet. Die Tüllen a, b sind spiegelsymmetrisch zu c,d angeordnet, und die Tüllen a, c sind spiegelsymmetrisch zu b, d angeordnet.A device according to the invention is fastened to a frame spar 1, which carries a side wall 7, by means of a screw 2. This has a double angled holding plate 3, which carries four grommets a, b, c, d, the curved longitudinal directions of which lie in the common plane of the drawing in FIG. 2 and which lie opposite one another in pairs. All four spouts open into a common, central cavity 4. They are held together by two clamps 5 and 6, respectively, which are fastened to the holding plate 3. With regard to two planes of symmetry running perpendicular to the plane of the drawing - one horizontal and one vertical - the grommets are arranged mirror-symmetrically to each other. The spouts a, b are arranged mirror-symmetrically to c, d, and the grommets a, c are mirror-symmetrical to b, d.
Der Grund jeweils einer Tülle verläuft in einem Bogen von etwa 90° und weist in Längsrichtung einen Krümmungsradius R30 auf, der größer ist, als der Mindestbiegeradius von Lichtwellenleitern 8, 9, die in Figur 2 mit eingezeichnet sind.The base of each grommet runs in an arc of approximately 90 ° and has a radius of curvature R30 in the longitudinal direction which is greater than the minimum bending radius of optical fibers 8, 9, which are also shown in FIG. 2.
Die Einrichtung kann nach Bedarf an der rechten Seite des Gestells (wie dargestellt) oder an der linken Seite montiert sein. Dies ermöglicht die Montagefläche 3a des Haltebleches 3, die senkrecht auf derjenigen Richtung steht, in welcher die einander gegenüber liegenden Tüllenpaare a-c und b-d ineinander münden.The device can be mounted on the right side of the rack (as shown) or on the left side as required. This enables the mounting surface 3a of the holding plate 3, which is perpendicular to the direction in which the opposing pairs of grommets a-c and b-d open into one another.
Die auf der Gestellfront ankommenden Lichtwellenleiter 8,9 werden zunächst durch die Tüllen d, b und dann durch die beiden anderen Tüllen gefädelt. Hiebei kann der aus Richtung B kommende Lichtwellenleiter 9 in Richtung C (wie dargestellt) oder A innerhalb des Kabelraumes 10 geführt werden. Ein Lichtwellenleiterkabel oder Lichtwellenleiter 8 aus Richtung D wird entsprechend in eine der Richtungen A oder C geführt. Somit können mehrere Lichtwellenleiter oder Kabel knickfrei in den Kabelraum 10 geführt werden. The optical fibers 8, 9 arriving on the frame front are first threaded through the grommets d, b and then through the other two grommets. Here, the optical fiber 9 coming from direction B can be guided in direction C (as shown) or A within the cable space 10. An optical waveguide cable or optical waveguide 8 from direction D is guided in one of directions A or C accordingly. Thus, several optical fibers or cables can be led into the cable space 10 without kinks.
