Description
Abdeckung für einen Lichtwellenleiterspleiß Cover for a fiber optic splice
Die vorliegende Erfindung betrifft eine Abdeckung für einen Lichtwellenleiterspleiß, bestehend aus zwei Plättchen, die beide auf einer Seite mit einem klebenden Material beschichtet sind, wobei die Plättchen, mit ihren klebenden Flächen aufeinandergelegt, den Spleiß zwischen sich aufnehmen.The present invention relates to a cover for an optical fiber splice, Consists of two platelets, both on one side with an adhesive material are coated, whereby the platelets, with their adhesive surfaces placed one on top of the other, take up the splice between them.
Eine derartige Spleißabdeckung ist bekannt aus G. K. Pacey and J. R. Scott," A Splicing System for Optical Fiber Cables", International Wire & Cable Symposium Proceedings 1981, 5.362-369. Die hier verwendeten Plättchen weisen keine besonderen Mittel auf, welche verhindern, daß die aufeinander gelegten Plättchen sich gegenseitig in lateraler und axialer Richtung zu den zwischen ihnen liegenden Lichtwellenleitern verschieben. Diese Aufgabe müßte die Klebeschicht übernehmen; das kann aber nur ein Klebematerial, welches mit der Zeit aushärtet. Ein solches aushärtendes Klebematerial hat aber den Nachteil, daß es auf die darin eingebetteten Lichtwellenleiter einen zu hohen Druck ausübt, was zu einer Dämpfungserhöhung in den Lichtwellenleitern führt.Such a splice cover is known from G. K. Pacey and J. R. Scott, "A Splicing System for Optical Fiber Cables," International Wire & Cable Symposium Proceedings 1981, 5,362-369. The platelets used here point no special means to prevent the stacked platelets mutually in the lateral and axial directions to those between them Move fiber optics. The adhesive layer would have to take on this task; but only an adhesive material that hardens over time can do this. One such curing adhesive material has the disadvantage that it is embedded in it Optical fiber exerts too high a pressure, which leads to an increase in attenuation in the fiber optics leads.
Der Erfindung liegt nun die Aufgabe zugrunde, eine Abedeckung für einen Lichtwellenleiterspleiß der eingangs genannten Art anzugeben, die dem Spleiß auf Dauer einen sicheren Schutz bietet, dabei aber eine dämpfungserhöhende mechanische Belastung der verspleißten Lichtwellenleiter vermeidet.The invention is now based on the object of a cover for specify an optical waveguide splice of the type mentioned, which is the splice offers reliable protection in the long term, but mechanical damping-enhancing Avoids stress on the spliced fiber optic cable.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das klebende Material dauerelastisch ist und daß die beiden Plättchen an den Rändern abgewinkelte Laschen aufweisen, die derart bemessen und in einem solchen Abstand voneinander angeordnet sind, daß die Laschen des einen Plättchens jeweils in die Lücken zwischen den Laschen des anderen Plättchens eingreifen.According to the invention this object is achieved in that the adhesive Material is permanently elastic and that the two plates are angled at the edges Have tabs that are sized and at such a distance from each other are arranged that the tabs of a plate each in the gaps between engage the tabs of the other plate.
Als klebendes, dauereleastisches Material zwischen den Plättchen wird zweckmäßigerweise Polyisobutylen verwendet. Dieses Material hat die vorteilhafte Eigenschaft, daß es sehr temperaturbeständig und feuchtigkeitsisolierend ist.As an adhesive, permanently elastic material between the plates expediently used polyisobutylene. This material has the beneficial Property that it is very temperature-resistant and moisture-insulating.
Anhand eines in der Zeichnung dargestellen Ausführungsbeispiels wird nachfolgend die Erfindung näher erläutert.Based on an embodiment shown in the drawing the invention is explained in more detail below.
Die in der Figur dargestelle Abdeckung für einen Lichtwellenleiterspleiß besteht aus zwei Plättchen 1 und 2, die beide auf einer Seite mit einer Schicht 3,4 aus Polyisobutylen belegt sind. Zwischen den Plättchen 1,2 sind zwei miteinander verspleißte Lichtwellenleiter 5 und 6 eingefügt. Werden nun die Plättchen aufeinander gedrückt, so haften die Polyisobutylenschichten 3 und 4 aufgrund ihrer Klebewirkung fest zusammen.The cover shown in the figure for an optical fiber splice consists of two platelets 1 and 2, both on one side with a layer 3.4 are occupied by polyisobutylene. Between the platelets 1,2 are two together spliced optical waveguides 5 and 6 inserted. Now the tiles are on top of each other pressed, the polyisobutylene layers 3 and 4 adhere due to their adhesive effect firmly together.
Dabei umgibt das dauerelastische Schichtenmaterial den Spleiß, ohne daß auf die Lichtwellenleiter ein zu hoher Druck ausgeübt wird, der zu Dämpfungserhöhung führen könnte. Der Lichtwellenleiterspleiß ist damit vor mechanischen Beanspruchungen sehr gut geschützt.The permanently elastic layer material surrounds the splice without that too high a pressure is exerted on the optical waveguide, which leads to an increase in attenuation could lead. The fiber optic splice is thus protected from mechanical stresses very well protected.
An den Rändern parallel zu den Lichtwellenleitern sind beide Plättchen 1, 2 mit Laschen 7,8 versehen, die um 90 0 zu den mit dem klebenden, dauerelastischen Material beschichteten Flächen abgewinkelt sind. Die Laschen 7,8 beider Plättchen haben gleich große Abmessungen und sind jeweils versetzt zueinander so angeordnet, daß die Laschen 6 des unteren Plättchens 1 zahnartig zwischen die Laschen 8 des oberen Plättchens 2 greifen. Die Lücke zwischen zwei Laschen ist jeweils so groß, daß dort genau eine andere Lasche hineinpaßt. Diese miteinander verzahnten Laschen verhindern ein gegenseitiges Verschieben der beiden Plättchen sowohl in lateraler als auch in axialer Richtung zu den Lichtwellenleitern.At the edges, parallel to the optical fibers, are both small plates 1, 2 provided with tabs 7, 8, which by 90 0 to the with the adhesive, surfaces coated with permanently elastic material are angled. The tabs 7,8 both plates have the same size and are offset from one another arranged so that the tabs 6 of the lower plate 1 tooth-like between the Grasp the tabs 8 of the upper plate 2. The gap between two tabs is each so big that another tab fits exactly there. These interlocked Lugs prevent the two plates from shifting in both directions laterally as well as in the axial direction to the optical waveguides.
