Description

Die Erfindung bezieht sich auf einen LWL-Steckverbinder für Einschubsysteme der Fernmeldetechnik gemäß dem Ober­ begriff des Anspruches 1.The invention relates to an optical fiber connector for slide-in systems for telecommunications according to the Ober Concept of claim 1.

Derartige LWL-Steckverbinder sind aus DIN 47 257, Teil 3, vorbekannt. Die Anordnung der LWL-Steckverbinder zwischen einem Gestell und einem Einschub ist aus telcom report 10 (1987), Seite 24, Bild 6, vorbekannt. Beim Einstecken des Einschubsteckers in die Einschubkupplung des LWL-Steck­ verbinders und insbesondere beim Herausziehen des Ein­ schubsteckers aus der Einschubkupplung sind Probleme auf­ getreten, die auf eine Klemmung in Folge des axialen Spiels der Einschubkupplung im Halter sowie den Ferti­ gungstoleranzen von Einschubkupplung und -stecker zurück­ zuführen sind. Die Einschubkupplung ist mit ihrem Ansatz in einer im Durchmesser etwas größeren Montageöffnung des Halters aufgenommen und trotz der auf das Außengewinde des Ansatzes aufgeschraubten Mutter in Axialrichtung und Radialrichtung innerhalb der Montageöffnung beweglich. Beim Verbinden des LWL-Steckverbinders mit einem vom Ge­ stell zugeführten Verbindungskabel über einen Handstecker werden von diesem Verbindungskabel herrührende Spannungen auf den LWL-Steckverbinder aufgebracht, die dazu führen, daß dieser mit seiner Achse gegenüber der Steckachse des Einschubsteckers geneigt wird, woraus die oben beschrie­ benen Klemmwirkungen resultieren. Darüber hinaus ist der LWL-Steckverbinder mittels der im Querschnitt rechteckigen Mutter im Halter derart lagegesichert, daß eine Verdrehung des LWL-Steckverbinders um seine Achse nur in geringem Maße möglich ist. Hierdurch kann die zur Verdrehsicherung im LWL-Steckverbinder auf der Anschlußseite für das Ver­ bindungskabel vorgesehene Nut von der am Handstecker des Verbindungskabels angebrachten Nase nur dann erreicht wer­ den, wenn das Verbindungskabel entsprechend gerdreht wird. Dieses notwendige Verdrehen des Verbindungskabels bringt eine zusätzliche Torsionsspannung auf den LWL-Steckverbin­ der, die sich der Auslenkung aus der Achse des Einschub­ steckers noch überlagert.Such fiber optic connectors are from DIN 47 257, part 3, previously known. The arrangement of the FO connectors between one frame and one insert is from telcom report 10 (1987), page 24, picture 6, previously known. When inserting the Insert plug into the insertion coupling of the fiber optic plug connector and especially when pulling out the one push plug from the plug-in coupling are problems stepped on a clamping as a result of the axial Game of the plug-in coupling in the holder and the Ferti tolerance of plug-in coupling and plug back are to be fed. The plug-in coupling is with its approach in a slightly larger mounting opening of the Holder included and despite the on the external thread the approach screwed nut in the axial direction and Radial direction movable within the mounting opening. When connecting the fiber optic connector with a Ge connect connecting cables via a hand plug voltages originating from this connecting cable applied to the fiber optic connector, which cause that this with its axis opposite the thru-axle of Insert plug is inclined, from which the above described clamping effects result. In addition, the FO connectors using the rectangular cross-section  Locked nut in the holder in such a way that a twist of the fiber optic connector only slightly around its axis Dimensions is possible. This can be used to prevent rotation in the fiber optic connector on the connection side for ver Connection cable provided groove of the on the hand plug of the Connecting cable attached nose only then who reaches if the connecting cable is turned accordingly. This necessary twisting of the connecting cable brings an additional torsional tension on the fiber optic connector the one that is the deflection from the axis of the insert plug still superimposed.

Der Erfindung liegt von daher die Aufgabe zugrunde, einen LWL-Steckverbinder der gattungsgemäßen Art zu schaffen, der einerseits für den Einschubstecker axial fluchtend und andererseits drehbar im Halter aufgenommen werden kann.The invention is therefore based on the object To create fiber optic connectors of the generic type, the one for the plug-in connector axially aligned and on the other hand, can be rotatably received in the holder.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeich­ nenden Merkmalen des Anspruches 1. Durch Verwendung der unter Wirkung der sich an der Mutter abstützenden Druck­ feder gegen den Halter drückbaren Scheibe wird erreicht, daß sich der LWL-Steckverbinder im Halter axial fluchtend zum Einschubstecker einstellt und auch unter Einwirkung eines vom Verbindungkabel herrührenden Torsionsmomentes leicht um seine Steckachse neigen läßt, so daß beim Ein­ stecken des Einschubsteckers in den LWL-Steckverbinder und beim Herausziehen des Einschubsteckers aus dem LWL- Steckverbinder keine Klemmwirkung auftritt. Darüber hinaus ist der LWL-Steckverbinder um seine Steckachse drehbar, so daß die auf der für das Verbindungskabel vorgesehenen An­ schlußseite des LWL-Steckverbinders angeordnete Nut leicht in die Flucht der Nase gedreht werden kann, welche als Verdrehsicherung am Handstecker des Verbindungskabels an­ gebracht ist. Somit wirkt kein zusätzliches Torsionsmoment auf den LWL-Steckverbinder ein. The solution to this problem results from the characteristics nenden features of claim 1. By using the under the pressure of the mother disc that can be pressed against the holder is reached that the fiber optic connector is axially aligned in the holder to the plug-in connector and also under influence a torsional moment originating from the connecting cable can easily tilt around its thru-axle, so that when entering insert the plug-in connector into the fiber optic connector and when pulling out the plug connector from the fiber optic Connector no clamping effect occurs. Furthermore is the fiber optic connector rotatable about its thru axis, so that the on the intended for the connecting cable groove on the end of the fiber optic connector can be turned into the flight of the nose, which as Anti-rotation device on the hand connector of the connecting cable brought. So there is no additional torsional moment on the fiber optic connector.  

Weitere vorteilhafte Ausgestaltungen der Erfindung erge­ ben sich aus den Unteransprüchen.Other advantageous embodiments of the invention are derived from the subclaims.

Der Erfindung ist nachfolgend anhand eines in den Zeich­ nungen dargestellten Ausführungsbeispieles eines LWL- Steckverbinders näher erläutert. Es zeigtThe invention is based on a in the drawing illustrated embodiment of an optical fiber Connector explained in more detail. It shows

Fig. 2 einen Längsschnitt durch den LWL-Steck­ verbinder. Fig. 2 shows a longitudinal section through the fiber optic connector.

Die Fig. 1 zeigt ein Gestell 1 und einen in dieses ein­ setzbaren Einschub 2 eines Einschubsystemes der Fernmel­ detechnik. Im Gestell 1 verlaufen in vertikaler Richtung Verbindungskabel 3, die um etwa 90° umgelenkt sind und in Handsteckern 4 enden. Auf der Rückseite des Einschu­ bes 2 ist ein Einschubstecker 5 fest montiert. Der Hand­ stecker 4 des Verbindungskabels 3 und der Einschub­ stecker 5 des Einschubes 2 werden über einen LWL-Steck­ verbinder 6 miteinander verbunden, der in einem gestell­ festen Halter 7 aufgenommen ist. Der Einschub 2 des Ein­ schubsystemes der Fernmeldetechnik enthält nicht näher dargestellte opto-elektronische Sende- und Empfangsein­ richtungen, welche über die Einschubstecker 5 und den LWL-Steckverbinder 6 mit dem Handstecker 4 des Verbin­ dungskabels 3 zu verbinden sind. Fig. 1 shows a frame 1 and in this a settable insert 2 of an insertion system of telecommunications technology. In the frame 1 extending in the vertical direction, connecting cable 3, which are deflected by about 90 ° and terminate in hand connectors. 4 On the back of the insert 2 , a plug-in connector 5 is permanently mounted. The hand connector 4 of the connecting cable 3 and the plug connector 5 of the insert 2 are connected to one another via an optical fiber plug connector 6 , which is accommodated in a frame-fixed holder 7 . The insert 2 of a plug-in system for telecommunications contains opto-electronic transmitting and receiving devices (not shown in more detail) which are to be connected via the plug-in connector 5 and the fiber optic connector 6 to the hand connector 4 of the connecting cable 3 .

Der in Fig. 2 im Querschnitt dargestellte LWL-Steckver­ binder 6 enthält eine nach DIN 47 256/47 257 ausgebildete Steckbuchse 10, auf welche eine Einschubkupplung 11 fest aufgeschraubt ist. Die Einschubkupplung 11 dient auf der in Fig. 2 dargestellten rechten Seite zum Einstecken des Einschubsteckers 5, der fest am Einschub 2 angebracht ist. Die Einschubkupplung 11 übergreift mit einem hül­ senförmigen Ansatz 12 den Längsmittelteil der Steck­ buchse 10 und ist mit der endseitigen Wandung 13 auf einen Gewindeansatz 14 der Steckbuchse 10 aufgeschraubt. Dieser Gewindeansatz 14 dient zum Aufschrauben des Hand­ steckers 4 des Verbindungskabels 3.The fiber optic connector 6 shown in cross section in FIG. 2 contains a socket 10 designed according to DIN 47 256/47 257, onto which an insertion coupling 11 is firmly screwed. The plug-in coupling 11 is used on the right-hand side shown in FIG. 2 for inserting the plug-in plug 5 , which is fixedly attached to the plug-in 2 . The slide coupling 11 engages with a projection 12 Sleeve Shirt senförmigen the longitudinal central part of the receptacle 10 and is screwed with the end wall 13 on a threaded shoulder 14 of the female connector 10 degrees. This threaded attachment 14 is used for screwing on the hand connector 4 of the connecting cable 3 .

An beiden stirnseitigen Enden der Steckbuchse 10 sind Schlitze 15 in der Mantelfläche der hohlen Steckbuchse 10 vorgesehen. Der Schlitz 15 auf der in Fig. 2 links dargestellten Seite der Steckbuchse 10 dient zum Einfüh­ ren einer Nase 16 des Handsteckers 4, welcher als Ver­ drehsicherung für das Verbindungskabel 3 vorgesehen ist.At both front ends of the socket 10 , slots 15 are provided in the outer surface of the hollow socket 10 . The slot 15 on the left in Fig. 2 side of the socket 10 serves to insert a nose 16 of the hand connector 4 , which is provided as a rotation lock for the connecting cable 3 .

Auf den mit einem Außengewinde versehenen hülsenförmigen Ansatz 12 der Einschubkupplung 11 ist eine Scheibe 20 aufgesteckt, welche gegen die Wandung 21 des Halters 7 anliegt, der wiederum am Kupplungskopf 22 der Einschub­ kupplung 11 anliegt. Die Scheibe 20 trägt auf einem kreisförmigen Ansatz 23 eine Druckfeder 24, welche wie­ derum auf einem entsprechenden kreisförmigen Ansatz 25 einer Mutter 26 aufliegt, welche auf den mit Außengewin­ de versehenen Ansatz 12 der Einschubkupplung 11 aufge­ schraubt ist.On the externally threaded sleeve-shaped extension 12 of the plug-in coupling 11 , a disc 20 is attached, which bears against the wall 21 of the holder 7 , which in turn bears against the coupling head 22 of the plug-in coupling 11 . The disc 20 carries on a circular extension 23 a compression spring 24 , which in turn rests on a corresponding circular extension 25 of a nut 26 which is screwed onto the externally threaded de extension 12 of the plug-in coupling 11 .

Die Scheibe 20 ist kreisförmig und die Mutter 26 ist achteckförmig ausgebildet.The disc 20 is circular and the nut 26 is octagonal.

Mittels der Mutter 26 wird die Vorspannung der Druckfe­ der 24 fixiert. Mit der Vorspannung der Druckfeder 24 drückt die Scheibe 20 gegen den Halter 7, in welchen der LWL-Steckverbinder 6 innerhalb der Montageöffnung 27 mit radialem Spiel eingesteckt ist. Die Anordnung der Druck­ feder 24 bewirkt einerseits, daß der LWL-Steckverbinder 6 mit fluchtender Steckachse 28 im Halter 7 aufgenommen ist. Andererseits kann der LWL-Steckverbinder 6 beim Auftreten einer über das Verbindungskabel 3 und den Hand­ stecker 4 eingeleiteten Spannung um seine Steckachse 28 geneigt werden. Diese Neigung ist federelastisch, so daß der von rechts in die Einschubkupplung 11 eingesteckte Einschubstecker 5 des Einschubes 2 ein elastisches Nach­ geben der Steckbuchse 10 sowohl beim Einstecken als auch beim Herausziehen bewirken kann. Klemmungen des Einschub­ steckers 5 im LWL-Steckverbinder 6 sind daher nicht zu befürchten. Darüber hinaus ist der LWL-Steckverbinder 6 auch um seine Steckachse 28 drehbar, so daß der Schlitz 15 fluchtend zur Nase 16 des Handsteckers 4 des Verbin­ dungskabels 3 eingestellt werden kann.By means of the nut 26 , the bias of the Druckfe 24 is fixed. With the pretension of the compression spring 24 , the disk 20 presses against the holder 7 , in which the fiber optic connector 6 is inserted with radial play within the mounting opening 27 . The arrangement of the compression spring 24 causes on the one hand that the fiber optic connector 6 with aligned thru axis 28 is received in the holder 7 . On the other hand, the fiber optic connector 6 can be inclined about its plug axis 28 when a voltage introduced via the connecting cable 3 and the hand plug 4 occurs . This inclination is resilient so that the plug-in plug 5 of the plug-in 2 inserted from the right into the plug-in coupling 11 can give an elastic after the socket 10 both when plugging in and when pulling out. Pinches of the plug 5 in the fiber optic connector 6 are therefore not to be feared. In addition, the fiber optic connector 6 is also rotatable about its thru axis 28 , so that the slot 15 in alignment with the nose 16 of the hand connector 4 of the connec tion cable 3 can be adjusted.

Der gemäß Fig. 2 von rechts in die Einschubkupplung 11 des LWL-Steckverbinders 6 eingesteckte Einschubstecker 5 umgreift das in Fig. 2 rechts dargestellte Ende der Steckbuchse 10. Deren konkrete innere Ausbildung ist in DIN 47 256/47 257 näher beschrieben, auf welche ausdrück­ lich verwiesen wird.The FIG. 2 from the right inserted into the insertion coupling 11 of the optical connector plug insertion 6 5 engages around the end of the female connector 10 shown in Fig. 2 to the right. Their specific internal training is described in more detail in DIN 47 256/47 257, to which express reference is made.

Bei den an den LWL-Steckverbindern 6 angeschlossenen Ka­ beln handelt es sich um Lichtwellenleiter (LWL).The cables connected to the FO connectors 6 are optical fibers.
