Abstract

A fibre holder holds optical fibres in position in an optical fibre connector. The optical fibre connector consists of a profiled base body and at least a covering body. A fibre holder which consists of two half-shells each provided with an optical fibre receiving groove which extends coaxially to their longitudinal axis is laid into the optical fibre connector. A ring-shaped, semi-circular protruding web is formed on the half-shells (17, 18) which constitute the optical fibre holder. An outer clamping device (1) sits on the web when the optical fibre holder (2) is assembled.

Description

Faserhalter Fiber holder
Die Erfindung betrifft einen Faserhalter für Lichtwellen¬ leiter zur Lagefixierung in einer Anschlußvorrichtung für Lichtwellenleiter, die aus einem Grundprofilkörper und mindestens einem Abdeckkörper besteht, die miteinander verbindbar sind und Nuten aufweisen, in die die Faserhalter und die Lichtwellenleiter eingelegt werden, wobei die Faserhalter aus jeweils zwei Halbschalen mit einer koaxial zu deren Längsachse ausgebildeten Nut zur Aufnahme eines Lichtwellenleiters bestehen und in der Anschlußvorrichtung durch eine äußere Klemmeinrichtung zusammengehalten werden, die auf die Halterhälften geschoben wird.The invention relates to a fiber holder for optical waveguides for fixing the position in a connecting device for optical fibers, which consists of a basic profile body and at least one cover body, which can be connected to one another and have grooves into which the fiber holders and the optical fibers are inserted, the fiber holders each consisting of two half shells with a coaxial to their longitudinal axis groove for receiving an optical waveguide and are held together in the connecting device by an external clamping device which is pushed onto the holder halves.
Ein derartiger Faserhalter ist nach der DE 92 10 401 Ul bekannt. Bei diesem Faserhalter sind an den Halterhälften im mittleren Bereich halbkreisförmige Material¬ verdickungen ausgebildet, um die beim Zusammenbau der Halterhälften ein Klemmring befestigt wird. Der Nachteil bei diesem Faserhalter besteht darin, daß bei nicht zu vermeidenden Toleranzungenauigkeiten des Innendurch¬ messers des Klemmrings dieser lose auf den Materialver¬ dickungen sitzen und sich verschieben kann, wodurch der Einbau in die für die Materialverdickungen vorgesehenen Ausnehmungen im Grundprofilkörper und dem mindestens einen Abdeckkörper nicht möglich ist.Such a fiber holder is known from DE 92 10 401 Ul. In this fiber holder, semicircular material thickenings are formed on the holder halves in the central region, around which a clamping ring is fastened when the holder halves are assembled. The disadvantage of this fiber holder is that if the inaccurate tolerances of the inside diameter of the clamping ring cannot be avoided, the clamping ring can sit loosely on the material thickenings and move, as a result of which the installation in the recesses provided for the material thickenings in the base profile body and the at least one cover body not possible.
Die Aufgabe der Erfindung besteht darin, den Faserhalter der eingangs genannten Art so zu verbessern, daß die äußere Klemmeinrichtung auf den aufeinanderliegenden Halterhälften gegen Verrutschen gesichert angeordnet werden kann.The object of the invention is to improve the fiber holder of the type mentioned in such a way that the outer clamping device can be arranged secured against slipping on the superimposed holder halves.
Erfindungsgemäß erfolgt die Lösung der Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung werden in den abhängigen Ansprüchen beschrieben.According to the invention, the object is achieved by the characterizing features of claim 1. Advantageous Embodiments of the invention are described in the dependent claims.
Der erfindungsgemäße Faserhalter ist vorzugsweise ein mehrteiliger Kunststoffkörper, der zusammengesetzt einen Faserkontakt darstellt. Der Faserhalter besteht aus zwei gleichartigen Halterhälften zwischen denen ein Lichtwellenleiter wie eine Glasfaser mit Kunststoff- beschichtung problemlos eingelegt und festgeklemmt werden kann. In den Nuten der Halterhälften wird der Lichtwellenleiter geführt, wobei durch eine besondere Oberflächenauslegung hohe Zugentlastungskräfte erzielbar sind.The fiber holder according to the invention is preferably a multi-part plastic body which, when put together, represents a fiber contact. The fiber holder consists of two identical holder halves between which an optical fiber such as a glass fiber with a plastic coating can be inserted and clamped without any problems. The optical waveguide is guided in the grooves of the holder halves, whereby high tensile relief forces can be achieved through a special surface design.
Die Erfindung wird nachstehend am Beispiel des in den Zeichnungen dargestellten Faserhalters näher erläutert. Es zeigt:The invention is explained below using the example of the fiber holder shown in the drawings. It shows:
Fig. 1 einen Faserhalter in der Seitenansicht im teilweisen Schnitt,1 is a fiber holder in side view in partial section,
Fig. 2 den Faserhalter nach Fig. 1 in der Drauf¬ sicht mit abgeschliffenem Stirnabschnitt,2 is a top view of the fiber holder according to FIG. 1 with a ground end section,
Fig. 3 einen Faserhalter nach Fig. 1 mit einer weiteren Ausbildung einer Klemmeinrichtung in der Seitenansicht,3 shows a side view of a fiber holder according to FIG. 1 with a further embodiment of a clamping device,
Fig. 4 eine Halterhälfte des Faserhalters nach und 5 Fig. 1 in der Draufsicht und Seitenansicht,4 shows a holder half of the fiber holder according to and FIG. 1 in top view and side view,
Fig. 6 eine weitere Ausbildung eines Faserhalters in der Seitenansicht im Schnitt,6 shows a further embodiment of a fiber holder in a side view in section,
Fig. 7 den Faserhalter nach Fig. 6 mit einsatzfer¬ tiger Kontaktspitze. Jeder Faserhalter 2 besteht aus zwei Halterhälften 17, 18, in denen jeweils mittig eine sich koaxial zur Längs¬ achse 14 des Faserhalters 2 erstreckende Nut 21 zur Auf¬ nahme eines Lichtwellenleiters ausgebildet ist. Das Mittelteil 30 eines jeden Faserhalters 2 weist zwei an den Halterhälften 17, 18 ausgebildete halbzylinderför ige Materialverdickungen 19 auf, an deren einem Endabschnitt 3 ein gegenüber den Materialverdickungen 19 vorragender halbkreisringförmiger Steg 4 ausgeformt ist. An den auf- einander zur Anlage kommenden Flächen 23 der Halterhälf¬ ten 17, 18 sind Sacklöcher 25 und Zapfen 26 sowie ein Steg 27 ausgebildet. Die Zapfen 26 und der Steg 27 sind bei Aufeinanderlage der beiden Halterhälften 17, 18 in jeweils zugehörige Sacklöcher 25 eingeführt, so daß die Halterhälften 17, 18 sich nicht aufeinander verschieben können. In dieser Lage wird auf die Materialverdickungen 19 eine Klemmeinrichtung 1 bis zur Anlage an die Stege 4 geschoben. Die Klemmeinrichtung 1 kann eine Klemmbuchse 15 oder eine Feder 5 sein. Die Verwendung einer Feder 5 ist besonders dann vorteilhaft, wenn bei Klemmbuchsen 15 bestehende Probleme hinsichtlich der Innendurchmesser¬ toleranzen vermieden werden sollen.7 shows the fiber holder according to FIG. 6 with a contact tip ready for use. Each fiber holder 2 consists of two holder halves 17, 18, in each of which a groove 21, which extends coaxially to the longitudinal axis 14 of the fiber holder 2, is formed in the center for receiving an optical waveguide. The middle part 30 of each fiber holder 2 has two semi-cylindrical material thickenings 19 formed on the holder halves 17, 18, at one end section 3 of which a semicircular web 4 projecting from the material thickenings 19 is formed. Blind holes 25 and pins 26 and a web 27 are formed on the surfaces 23 of the holder halves 17, 18 that come into contact with one another. The pins 26 and the web 27 are inserted when the two holder halves 17, 18 lie one on top of the other in the respective blind holes 25, so that the holder halves 17, 18 cannot move towards one another. In this position, a clamping device 1 is pushed onto the material thickenings 19 until it abuts against the webs 4. The clamping device 1 can be a clamping bush 15 or a spring 5. The use of a spring 5 is particularly advantageous if existing problems with regard to the inner diameter tolerances are to be avoided in the case of clamping bushes 15.
Es ist auch möglich, die Klemmeinrichtung 1 als elastischen Rollring aus Gummi od. dgl. auszubilden. Sofern ein Rollring für eine solche Verbindung der Halterhälften 17, 18 nicht ausreichend ist, können weitere Rollringe auf die Materialverdickungen 19 geschoben werden.It is also possible to design the clamping device 1 as an elastic rolling ring made of rubber or the like. If a rolling ring is not sufficient for such a connection of the holder halves 17, 18, further rolling rings can be pushed onto the material thickenings 19.
Fig. 6 zeigt einen Faserhalter 12, der ebenfalls aus zwei Halterhälften 17, 18 besteht. Die Stege 4 sind an dem einen Endabschnitt 6 der Halterhälften 17, 18 angeordnet. An dem anderen Endabschnitt 8 sind die Halterhälften 17, 18 wie auch beim Faserhalter 2 abgeschrägt ausgebildet. Als Klemmeinrichtung 1 dient eine Klemmbuchse 15, die auf die Halterhälften 17, 18 bis zur Anlage an den Stegen 4 geschoben ist. Den einbaufertigen Zustand des Faserhalters 12 mit einem Lichtwellenleiter 7 zeigt Fig. 7. Hierbei ist der Stirnabschnitt 28 des Faserhalters 12 plangeschliffen und poliert.Fig. 6 shows a fiber holder 12, which also consists of two holder halves 17, 18. The webs 4 are arranged on one end section 6 of the holder halves 17, 18. At the other end section 8, the holder halves 17, 18 are also bevelled, as is the case with the fiber holder 2. A clamping bush 15 is used as the clamping device 1, which fits onto the holder halves 17, 18 until it abuts the webs 4 is pushed. The ready-to-install state of the fiber holder 12 with an optical waveguide 7 is shown in FIG. 7. Here, the end section 28 of the fiber holder 12 is ground and polished.
Vor Einsetzen eines jeden Faserhalters 2 in den jeweiligen Grundprofilkörper einer Anschlußvorrichtung wird in bekannter Weise der jeweilige Stirnabschnitt 28 des Faserhalters 2 mit den eingeklemmten Lichtwellen- leitern rechtwinklig zur Längsachse 14 des Faserhalters 2 plangeschliffen und poliert. Hierdurch entsteht eine definierte Übertragungsflache für Meßwerte, die an dem jeweiligen optischen oder optoelektronischen Koppelglied unverrückbar anliegt, sofern der oder die Abdeckkörper fest mit dem Grundprofilkörper verbunden sind. Durch die besondere Kontaktgestaltung wird kein weiteres Installationswerkzeug für die Positionierung und Halterung des Lichtwellenleiters benötigt. Dieser braucht nicht abisoliert und z. B. mit einem Kleber in der Anschlußvorrichtung befestigt werden. Als Anschlußvor¬ richtung können Einzel- und Mehrfachstecker dienen, für die die Faserhalter 2, 12 geeignet sind. Bei der Installation von Einzelsteckern kann im Regelfall auf eine Klemmbuchse od. dgl. als Klemmeinrichtung verzichtet werden, da der Steckerkörper die Funktion einer Klemmeinrichtung übernimmt. Der unterschiedlich der jeweiligen Steckerart angepaßte Faserhalter mit Lichtwellenleiter wird bis zum rückwärtigen Anschlag in das Gehäuse des Steckers eingeschoben. Der Stirnabschnitt 28 des Faserhalters 2 einschließlich Lichtwellenleiter wird dann nach Fertigstellung der Steckerinstallation abgeschliffen und auspoliert.Before each fiber holder 2 is inserted into the respective basic profile body of a connecting device, the respective end section 28 of the fiber holder 2 with the clamped optical waveguides is ground and polished at right angles to the longitudinal axis 14 of the fiber holder 2 in a known manner. This creates a defined transmission area for measured values, which rests immovably on the respective optical or optoelectronic coupling element, provided that the cover body or bodies are firmly connected to the base profile body. Due to the special contact design, no additional installation tools are required for the positioning and mounting of the optical fiber. This does not need to be stripped and z. B. with an adhesive in the connector. Single and multiple plugs for which the fiber holders 2, 12 are suitable can serve as the connecting device. When installing individual plugs, a clamping bush or the like can generally be dispensed with as a clamping device, since the plug body takes on the function of a clamping device. The fiber holder with optical waveguide, which is adapted differently to the respective connector type, is pushed into the housing of the connector up to the rear stop. The end section 28 of the fiber holder 2 including the optical waveguide is then ground and polished after completion of the plug installation.
Die erforderliche Zugentlastung des Lichtwellenleiters kann mit einer Einklemmvorrichtung durch Verschraubung und/oder Verrastung erfolgen. The necessary strain relief of the optical fiber can be done with a clamping device by screwing and / or locking.
