Aus der
Aufgabe der Erfindung ist es demnach, eine Einrichtung zur kontaktlosen Übertragung von Wechselsignalen zu schaffen, die nicht nur sehr einfach in ihrer konstruktiven Ausgestaltung und damit wirtschaftlich herzustellen ist, sondern die auch klein baut und äußerst vielseitig eingesetzt werden kann. Vor allem soll erreicht werden, daß eine hohe Datenübertragungsrate gegeben und ohne Schwierigkeiten auch eine Abschirmung gegen Störfelder zu bewerkstelligen ist, so daß die Einrichtung auch in einer gestörten Umgebung verwendet werden kann.The object of the invention is therefore a device for the contactless transmission of alternating signals to create that not only very simple in their constructive design and is therefore economical to manufacture, but also builds small and extremely versatile can be used. Above all, it should be achieved that a high Data transfer rate given and without difficulty also shielding against interference fields is to be accomplished so that the Establishment even in a disturbed Environment can be used.
Gemäß der Erfindung wird dies bei einer Einrichtung zur kontaktlosen Übertragung von Wechselsignalen der vorgenannten Gattung durch die Merkmale des Patentanspruches 1 erreicht.According to the invention, this is at a device for the contactless transmission of alternating signals the aforementioned type by the features of the claim 1 reached.
Weitere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous developments the invention emerge from the subclaims.
Wird eine Einrichtung zur kontaktlosen Übertragung von Wechselsignalen gemäß der Erfindung ausgebildet, so ist nicht nur eine kraftfreie und berührungslose Übertragung von analogen oder digitalen Wechselsignalen von einem Sender zu einem Empfänger problemlos bei störungsfreiem Betrieb zu bewerkstelligen, sondern es ist auch eine hohe Datenübertragungsrate gegeben. Werden nämlich de Sender und der Empfänger als flächige auf einem starren Träger aufgebrachte und unmittelbar einander gegenüberliegend angeordnete Antennen ausgebildet, so ist es möglich, diese auf sehr einfache Weise gegen Störfelder abzuschirmen. Außerdem weist die vorschlagsgemäß gestaltete Einrichtung ein geringes Eigengewicht auf, und diese baut auch klein, so daß, da somit nur wenig Bauraum zu deren Unterbringung erforderlich ist, ein vielseitiger Einsatz, gegebenenfalls auch in einer gestörten Umgebung, möglich ist.Becomes a device for contactless transmission of alternating signals according to the invention, So is not only a force-free and contactless transmission of analog or digital alternating signals from a transmitter to a receiver without any problems with trouble-free Operation accomplished, but there is also a high data transfer rate given. Because namely en Sender and receiver as flat on a rigid support applied and directly opposite antennas trained so it is possible shield them from interference fields in a very simple way. Also points the designed according to the proposal Device has a low weight, and it also builds small, so that there therefore only little installation space is required to accommodate them, versatile use, possibly also in a disturbed environment, possible is.
