Um die Grenzen konventioneller, elektrischer Verbindungen bei komplexen und leistungsfähigen Signalprozessoren zu überwinden, werden optische Verbindungen eingesetzt. In lokalen Verbindungssystemen z. B. bei Vernetzung von Baugruppen innerhalb eines Baugruppenträgers besteht die optische Verbindung von Board zu Board aus Sender, opti scher Backplane und Empfänger. In der Backplane sind ent sprechend der optischen Vernetzung die Lichtwege vorgege ben. Als Sender- und Empfängerelement kommen Halbleiter bauelemente wie Photodiode, LED, und Laser zum Einsatz. Zur Übertragung der Lichtsignale vom Board zur Backplane ist die Kopplung über eine kurze Freistrahlstrecke zwi schen boardseitigem Sender und Backplane eine geeignete Verbindung. Bei derartigen Verbindungen besteht die Not wendigkeit einer Schutzvorrichtung für den Lasersender, wenn das Board getrennt von der Backplane betrieben wird. Diese Schutzvorrichtung ist z. B. wichtig bei der Wartung oder bei Montagearbeiten, um die Augen von Personen vor gefährlicher Laserstrahlung zu schützen.The limits of conventional electrical connections with complex and powerful signal processors overcome, optical connections are used. In local connection systems e.g. B. when networking There are modules within a subrack optical connection from board to board from transmitter, opti shear backplane and receiver. In the backplane are ent the light paths are given according to the optical networking ben. Semiconductors come as transmitter and receiver elements Components such as photodiodes, LEDs and lasers are used. For the transmission of light signals from the board to the backplane is the coupling over a short free jet distance between suitable board-side transmitter and backplane Connection. There is a need for such connections maneuverability of a protective device for the laser transmitter, if the board is operated separately from the backplane. This protective device is e.g. B. important for maintenance or during assembly work to protect people's eyes protect dangerous laser radiation.
Aufgabe der Erfindung ist es deshalb, eine Vorrichtung anzugeben, durch die der Lichtstrahl vom Sender nicht in den freien Raum strahlen kann, wenn bei eingeschaltetem Betriebszustand die Verbindungsleiste von Baugruppenträ gern bzw. Sendern entfernt wird und die einfach und ko stengünstig herstellbar ist.The object of the invention is therefore a device specify by which the light beam from the transmitter is not in can shine the free space when switched on Operating status of the connecting bar of module likes or transmitters is removed and the simple and knockout is inexpensive to manufacture.
Die Aufgabe wird gelöst durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale. Vorteilhafte Ausgestaltungen und/oder Weiterbildungen sind den Unteransprüchen zu entnehmen.The task is solved by the in the characterizing part of claim 1 specified features. Beneficial Refinements and / or further developments are the subclaims refer to.
Die Erfindung hat den Vorteil, daß sich die Vorrichtung in einem Bereich des Senders befindet, in welchem der Strahldurchmesser noch sehr gering ist. Es sind deshalb nur sehr kleine Abmessungen der Bauteile, Umlenkelement und Metall feder, erforderlich. Insbesondere kann der Ver schiebungsweg zwischen Umlenkstellung und Durchlaßstellung der Vorrichtung sehr gering gehalten werden.The invention has the advantage that the device in an area of the transmitter in which the beam diameter is still very low. Therefore, they are only very small dimensions of the components, deflection element and metal feather, required. In particular, the Ver sliding distance between deflection position and open position the device can be kept very low.
Durch eine geneigte Anordnung des Umlenkelementes zur Strahlrichtung, z. B. die Neigung des Umlenkelementes um 45° zur Längsachse der Feder und die Umlenkung des Lichtes in eine Absorptionszone, die z. B. in der Metallhülse für die Linse eingebracht ist, treten lediglich geringe Rück reflexionen auf den Sender auf.Through an inclined arrangement of the deflecting element Beam direction, e.g. B. the inclination of the deflecting element 45 ° to the longitudinal axis of the spring and the deflection of the light in an absorption zone, the z. B. in the metal sleeve for the lens is inserted, there is only slight receding reflections on the transmitter.
Die Erfindung wird im folgenden anhand eines Ausführungs beispiels beschrieben unter Bezugnahme auf schematische Zeichnungen.The invention is based on an embodiment described for example with reference to schematic Drawings.
In einem Ausführungsbeispiel gemäß Fig. 1 besteht der Sen der 1 aus einem Laser in einem hermetisch dichtem Gehäuse. Eine Metallhülse 2 hält eine Kugellinse 3 in ihrer optimalen Lage vor dem Lasergehäuse. Die Kugellinse hat die Auf gabe vom Laser emittiertes Licht zu kollimieren. Sie ist mittels eines Befestigungsringes, durch Klebung oder Lö tung in der Metallhülse 2 fixiert. Zwischen Laser 1 und Kugellinse 3 ist eine z. B. winkelförmige Metallfeder 4 an geordnet, mit einem Umlenkelement 6, z. B. einer Metall scheibe. Sie durchdringt die Metallhülse 2 durch eine Boh rung 5 und ist mit ihrem einen Ende am Außenmantel der Me tallhülse befestigt. Das Umlenkelement 6 der Metallfeder 4 im Gehäuseinneren ist z. B. um 45° zur Längsachse der Me tallfeder gedreht und mit einer Öffnung versehen. Durch die Neigung des Umlenkelementes wird die Reflexion des Lichtes auf den Laser vermieden. In one embodiment according to FIG. 1, Sen 1 consists of a laser in a hermetically sealed housing. A metal sleeve 2 holds a ball lens 3 in its optimal position in front of the laser housing. The ball lens has the task of collimating light emitted by the laser. It is fixed by means of a fastening ring, by gluing or soldering in the metal sleeve 2 . Between laser 1 and ball lens 3 is a z. B. angular metal spring 4 arranged with a deflecting element 6 , z. B. a metal disc. It penetrates the metal sleeve 2 through a drilling tion 5 and is attached at one end to the outer casing of the tall sleeve. The deflecting element 6 of the metal spring 4 inside the housing is, for. B. rotated by 45 ° to the longitudinal axis of the tall spring Me and provided with an opening. Due to the inclination of the deflection element, the reflection of the light on the laser is avoided.
In der Ruhelage der Metallfeder (Fig. 1a) wird der vom La ser emittierte Lichtstrahl durch das Umlenkelement 6 der Feder auf eine absorbierende Zone 7 umgelenkt (Fig. 1b).In the rest position of the metal spring ( Fig. 1a), the light beam emitted by the laser is deflected by the deflecting element 6 of the spring onto an absorbing zone 7 ( Fig. 1b).
Dadurch kann kein Laserlicht durch die Kugellinse hindurch aus dem Gehäuse austreten. Die absorbierende Zone 7 ist beispielsweise in der Metallhülse eingebracht und kann aus einem schwarz eloxiertem Aluminiumteil rauher Oberfläche bestehen.As a result, no laser light can exit the housing through the ball lens. The absorbing zone 7 is, for example, introduced in the metal sleeve and can consist of a black anodized aluminum part with a rough surface.
Wird nun die Metallfeder 4 durch eine Kraft nach oben ge drückt, so wandert gleichzeitig die Öffnung im Umlenkele ment 6 der Feder nach oben und gibt den Lichtweg für das Laserlicht frei (Fig. 2). Laserlicht tritt nun ungehindert aus dem Sendergehäuse. Bei aufgesteckter Backplanleiste aber wird es gefahrlos und augensicher in den Lichtwellen leiter geführt.If the metal spring 4 is now pressed upward by a force, the opening in the deflecting element 6 of the spring simultaneously moves upward and releases the light path for the laser light ( FIG. 2). Laser light now emerges from the transmitter housing unhindered. When the back plan strip is attached, however, it is guided safely and eye-safe in the optical fibers.
Bei der Ausgestaltung des Umlenkelementes muß dabei die Öffnung derart angeordnet sein, daß der Verschiebeweg der Feder in gespannter Stellung dem Verschiebeweg der Öffnung auf der Metallscheibe entspricht.When designing the deflecting element, the Opening be arranged so that the displacement of the Spring in the cocked position the displacement of the opening on the metal disc.
Die Erfindung ist nicht auf das angegebene Ausführungsbei spiel beschränkt, sondern die Gestaltung des Umlenkelemen tes ist in andere die Umlenkung des Lichtes geeigneten formen denkbar. Auch die Neigung des Umlenkelementes ist verschieden einstellbar.The invention is not based on the stated embodiment game limited, but the design of Umlenkelemen It is suitable for deflecting the light into others shapes conceivable. The inclination of the deflecting element is also different adjustable.
