Abstract
Description
Die Erfindung bezieht sich auf einen optischen Schalter mit einem translatorisch bewegten oder schwenkbaren Schaltstück und mit wenigstens einem die Bewegung des Schaltstücks über ver längerte Hebelarme relativ zum Grundkörper führenden Material gelenk (Filmscharnier).The invention relates to an optical switch a translationally moved or swiveling contact piece and with at least one the movement of the contact piece via ver longer lever arms relative to the material guiding the body joint (film hinge).
Optische Schalter mit den zuvor erwähnten Merkmalen sind bereits aus den DE-OS 34 37 489 und DE-OS 37 41 761 bekannt. Bei diesen Schaltern wird die Bewegung des Schaltstücks von zwei oder mehr Blattfedern bzw. Federblechabschnitten geführt, so daß sich eine Parallel- bzw. eine Geradführung ergibt. Nachteilig ist der aus der Verwendung diskreter Bauteile resultierende hohe Montageaufwand.Optical switches with the aforementioned features are already known from DE-OS 34 37 489 and DE-OS 37 41 761. With these switches, the movement of the contact from guided two or more leaf springs or spring plate sections, so that there is parallel or straight guidance. The disadvantage of using discrete components resulting high assembly effort.
Der Erfindung liegt die Aufgabe zugrunde, für eine Verbesserung der Konstruktion eines solchen Schalters den hohen Montage aufwand erheblich zu reduzieren. Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß der Grundkörper, das Schaltstück, die Schwenkarme und die Materialgelenke material gleich und einstückig hergestellt sind. Hierdurch ergibt sich ein wesentlich verringerter Fertigungsaufwand bei gleichzeitig erhöhter Unempfindlichkeit gegenüber nicht zur Bewegungsebene parallelen Störkräften. Gleichzeitig wird durch die Material gleichheit aller Teile, insbesondere bei zusätzlicher An gleichung der Materialquerschnitte, eine Kompensation der temperaturunterschiedsbedingten Veränderung des Abstandes zwischen Schaltstück und Grundkörper erreicht.The invention is based, for an improvement the construction of such a switch the high assembly reduce effort significantly. To solve this problem proposed according to the invention that the base body, the Switch piece, the swivel arms and the material joints material are made the same and in one piece. This results in a significantly reduced manufacturing effort at the same time increased insensitivity to the plane of movement parallel interference forces. At the same time, through the material Equality of all parts, especially with additional parts equation of the material cross sections, a compensation of the change in distance due to temperature difference reached between contact and main body.
Die Erfindung wird anhand der nachstehend beschriebenen und in der Zeichnung dargestellten Ausführungsbeispiele im einzelnen erläutert. In der Zeichnung zeigt - jeweils in perspektivischer Darstellung -,The invention is described in the following and in the drawing shown embodiments in detail explained. The drawing shows - each in perspective Presentation -,
Fig. 1 einen optischen Schalter mit Parallelführung und Fig. 1 shows an optical switch with parallel guidance and
Fig. 2 einen optischen Schalter mit einfacher Schwenkführung. Fig. 2 shows an optical switch with a simple swivel guide.
Der in Fig. 1 perspektivisch dargestellte optische Schalter 10 besteht im wesentlichen aus einer Bodenplatte 11, einem Grundkörper 12 und einem Schaltstück 15. Grundkörper 12 und Schaltstück 15 dienen als Träger von Lichtwellenleitern 8, die untereinander unterschiedlich zu verbinden sind. Zu diesem Zweck wird das Schaltstück 15 über zwei Schwenkarme 16 gegen über dem Grundkörper 11 parallelgeführt. Für die bewegliche Verbindung sorgen an beiden Enden jedes Schwenkarmes Film scharniere 17. Dabei sind Grundkörper 12, Schaltstück 15, Schwenkarme 16 und Filmscharniere 17 materialgleich und ein stückig ausgebildet, so daß temperaturbedingte Längenänderungen weitgehend kompensiert werden.The optical switch 10 shown in perspective in FIG. 1 essentially consists of a base plate 11 , a base body 12 and a switching piece 15 . Base body 12 and switching piece 15 serve as carriers of optical fibers 8 , which are to be connected to one another differently. For this purpose, the switching piece 15 is guided in parallel via two swivel arms 16 relative to the base body 11 . The moveable connection is provided by film hinges 17 at both ends of each swivel arm. Base body 12 , switching piece 15 , swivel arms 16 and film hinges 17 are made of the same material and are of one piece, so that temperature-related changes in length are largely compensated for.
In Fig. 2 ist ebenfalls perspektivisch ein optischer Schalter 20 mit einfachem Schwenkarm dargestellt. Der besseren Übersicht halber sind die zu schaltenden optischen Elemente, die sich auf der Oberfläche des Grundkörpers 22 und des Schaltstücks 25 befinden müßten, nicht dargestellt. Auch in diesem Falle ist der Grundkörper 22 mit dem Schaltstück 25, das zugleich als Schwenkarm dient, über ein Filmscharnier 27 verbunden. Im teilweise aufgeschnittenen Grundkörper 22 ist das aus den Teilen 28 und 29 bestehende Anschlagsystem dargestellt.An optical switch 20 with a simple swivel arm is also shown in perspective in FIG. 2. For the sake of a better overview, the optical elements to be switched, which should be on the surface of the base body 22 and the switching element 25, are not shown. In this case too, the base body 22 is connected to the switching element 25 , which also serves as a swivel arm, via a film hinge 27 . The stop system consisting of the parts 28 and 29 is shown in the partially cut-open base body 22 .
