Abstract
Description
In der Fig. 4 ist dargestellt, wie die Lichtwellenleiterenden 4 in den V-Nuten 11a, 11b des Grundkörpers 1 und in der V-Nut 31a des zylinderförmigen Stiftes 31 aufliegen und wie die Durchmesserdifferenz ausgegli- chen wird. 4 shows how the optical fiber ends 4 in the V-grooves 11a, 11b of the base body 1 and in the V-groove 31a of the cylindrical Of pin 31 and how the difference in diameter is compensated chen will.
Die zusätzliche Toleranz einer exzentrischen Lage des Lichtwellenleiter-Kerns zum Coating hat somit keinen Einfluß auf die Dämpfungswerte. The additional tolerance of an eccentric position of the fiber optic core the coating has no influence on the damping values.
Um den zylinderförmigen Stift 31 schließt sich eine aus vier Spannbändern 32a, 32b, 32c, 32d ausgeführte Blechfeder 30. die im Grundkörper 1 - wie die Fig.3 zeigt - gehalten wird. One of four tensioning straps closes around the cylindrical pin 31 32a, 32b, 32c, 32d executed sheet metal spring 30. which in the base body 1 - like the Fig.3 shows - is held.
Mittels einer nicht dargestellten Vorrichtung werden die Spann bänder 32a, 32b, 32c, 32dso verformt, daß sich zwischen der V-Nut 31a des zylinderförmigen Stiftes 31 und den Spannbändern 32a, 32b, 32c, 32d eine Öffnung bildet, die so groß ist, daß die beiden Lichtwellenleiterenden frei hindurchgleiten können. Hierdurch ist gewährleistet, daß die Lichtwellenleiter-Frontflächen (Stirnflächen) bei der Montage nicht durch die Halteeinrichtung3 beschädigt werden. By means of a device, not shown, the tensioning straps 32a, 32b, 32c, 32ds so deformed that between the V-groove 31a of the cylindrical Pin 31 and the straps 32a, 32b, 32c, 32d forms an opening that is so large is that the two fiber optic ends can slide freely. Through this it is ensured that the optical waveguide front surfaces (end surfaces) at the Assembly cannot be damaged by the holding device3.
Je zwei der vier Spannbänder halten ein Lichtwellenleiterende 4, so daß die Haltekraft gleichmäßig verteilt wird. Zwischen den einzelnen Spannbändern wird die Positionierung der Lichtwellenleiter optisch überwacht. Two of the four tensioning straps each hold an optical fiber end 4, so that the holding force is evenly distributed. Between the individual straps the positioning of the fiber optic cables is monitored optically.
In einer weiteren Ausführungsmöglichkeit kann hier die unbehinderte Einbringung eines zusätzlichen, dämpfungsmindernden Mediums zwischen den Lichtwellenleiter-Endflächen erfolgen. Another option here is the unhindered Introduction of an additional, attenuation-reducing medium between the optical waveguide end faces take place.
In vorteilhafter Weise ist durch die Formgebung der Blechfeder 30 eine Festlegung unterschiedlicher Lichtwellenleiter-Durchmesser möglich, da die Spannbänder 32a, 32b, 32c, 32d mittels einer nicht dargestellten Vorrichtung durch die Öffnung 15 einzeln bewegt werden können. Zum Verschließen des Grundkörpers 1 ist -wie die F i g. l und 2 zeigen - eine Oberschale 2 vorgesehen. Diese Oberschale 2 besitzt vier Rastösen 22a, 22b, 22c, 22d, die in die Rasthaken 12a, 12b, 12c, 12ddes Grundkörpers 1 einrasten. The shape of the sheet metal spring 30 a definition of different fiber optic diameters possible, since the Tensioning straps 32a, 32b, 32c, 32d by means of a device not shown the opening 15 can be moved individually. To close the main body 1 is -like the fig. 1 and 2 show - an upper shell 2 is provided. This upper shell 2 has four locking eyes 22a, 22b, 22c, 22d, which are inserted into the locking hooks 12a, 12b, 12c, 12d of the base body 1 into place.
Zur Zugentlastung der Lichtwellenleiterenden 4 weist die Oberschale 2 zwei Flächen 23a, 23b auf, die die Lichtwellenleiterenden 4 in die V-Nuten 11a, 11h der Aussparungen 13a, 13b, des Grundkörpers 1 pressen und damit zugentlasten. Gleichzeitig wird die Spleißstelle gegen schädliche Umwelteinflüsse abgedichtet. To relieve the strain on the optical fiber ends 4, the upper shell 2 two surfaces 23a, 23b which the optical waveguide ends 4 in the V-grooves 11a, 11h of the recesses 13a, 13b of the base body 1 and thus relieve tension. At the same time, the splice point is sealed against harmful environmental influences.
An der Oberschale 2 sind außerdem zwei Dichtungsflächen 24a, 24b angeordnet, die in die Nuten 14a, 14b des Grundkörpers eingreifen, um die Spleißstellen gegen schädliche Umwelteinflüsse abzudichten. There are also two sealing surfaces 24a, 24b on the upper shell 2 arranged, which engage in the grooves 14a, 14b of the base body to the splice points to seal against harmful environmental influences.
