Die Neuerung betrifft einen Tastenwahlblock mit optoelektronischer Codierung, der alle bisher bekannten mechanischen und elektrischen Probleme auf neuartige Weise löst.The innovation concerns a keypad with optoelectronic Coding that addresses all previously known mechanical and electrical problems in a novel way solves.
Es ist bereits bekannt, die Kontaktgabe in Tastenwahlblocken
zum Zweck der Codierung für Diodenerdverfahren, Impulswahlverfahren und Mehrfrequenzwahlverfahren mit
Kontakten in herkömmlicher stehender Bauweise (z.B. DE*PS 12 05 587), liegender Bauweise (z.B.DE-OS 23 51
367) und auch in Schutzgastechnik auszuführen.
Allen diesen Verfahren haften mechanische und elektrische Mängel an, die durch die erfindungsgemäße Codierung
beseitigt werden.It is already known to make contacts in keypad selection blocks for the purpose of coding for diode earth procedures, pulse dialing procedures and multi-frequency dialing procedures with contacts in conventional vertical construction (e.g. DE * PS 12 05 587), horizontal construction (e.g. DE-OS 23 51 367) and also in protective gas technology .
All of these methods have mechanical and electrical defects which are eliminated by the coding according to the invention.
So treten insbesondere bei Kontakten in stehender Bauweise hohe Betätigungskräfte auf, die - bedingt durch mechanische Umlenkverfahren - verschleißträchtig sind.In particular, when the contacts are in an upright position, high actuation forces occur due to the mechanical deflection processes - are prone to wear and tear.
Bei Kontakten in liegender Bauweise verringern Verschmutzung und geringe Kontaktkräfte die Lebensdauer und Schutzgaskontakte haben unzureichende Kontakteigenschaften beim Übertragen kleinster Schaltleistungen.In the case of contacts in a horizontal design, contamination and low contact forces reduce the service life and inert gas contacts have inadequate contact properties when transmitting the smallest switching capacities.
Demgegenüber ist die vorliegende Neuerung aus der Aufgabe entstanden, einen weitgehend verschleißfreien kontaktsicheren Tastenwahlblock zu schaffen, der die bisherige mechanische Kontaktgabe durch eine neuartige optoelektronische Ausführung ersetzt.In contrast, the present innovation has arisen from the task of providing a largely wear-free, reliable contact To create keypad, the previous mechanical contact through a new optoelectronic version replaced.
Diese Ausführung besteht im wesentlichen aus einem orthogonalen System von sich kreuzenden lichtleitenden Kanälen, das an jedem Kreuzungspunkt ein in Form einer Taste mit zwei um 90° versetzten und im Abstand der sich kreuzenden Kanäle angebrachten lichtleitenden Durchbrüchen ausgebildetes Betätigungselement aufweist.This design essentially consists of an orthogonal system of intersecting light-conducting lines Channels, which at each intersection one in the form of a button with two offset by 90 ° and at a distance of having intersecting channels attached light-guiding openings formed actuating element.
Die Kanäle werden an ihrem einen Ende von Lichtquellen eingespeist, wobei - unter Verwendung eines entsprechend ausgebildeten lichtleitenden Systems - alle Kanaleingänge gemeinsam von einer Lichtquelle oder zur Funktionssicherheit bei Ausfall - aus mehreren Lichtquellen gespeist werden können.The channels are fed by light sources at one end, using a corresponding trained light-guiding system - all channel entrances together from a light source or to Functional reliability in the event of failure - can be fed from several light sources.

Das Betätigungselement taucht in den an dem jeweiligen Kreuzungspunkt zweier Kanäle befindlichen Schacht und verändert die Lichtintensität in den beiden Kanälen simultan.The actuating element dips into the shaft located at the respective intersection of two channels and changes the light intensity in the two channels simultaneously.
An den der Lichteinspeisung gegenüberliegenden Kanalenden befinden sich separate opotelektrische Einrichtungen, die die Veränderungen der Lichtintensität auswerten und aus denen die für das im Tastenwahlblock angewendete Wählverfahren (DEV, IWV, MFV) erforderlichen codierten Schaltfunktionen in bekannter Weise abgeleitet werden.At the channel ends opposite the light feed there are separate optical electrical devices that evaluate and evaluate the changes in light intensity which the coded switching functions required for the dialing method used in the keypad (DEV, IWV, MFV) can be derived in a known manner.
Die Figur 1 stellt das Funktionsprinzip .dar:
Sie zeigt die sich kreuzenden lichtleitenden Kanäle 1 mit
am Kanalanfang 4 liegenden Lichtquellen 6 und am Kanalende 5 befindlicher Optoelektronik 7.Figure 1 shows the functional principle .dar:
