Description
Die vorliegende Erfindung betrifft ein Schalt-/Anzeigegerät der Steuerungstechnik, mit mindestens einem Paar von Kontakten, an die geräteexterne Kabeladern anschließbar sind, wobei das Paar von Kontakten geräteintern über einen Schalter elektrisch miteinander verbindbar bzw. elektrisch voneinander trennbar ist bzw. über ein binäres Anzeigeelement elektrisch miteinander verbunden ist.The present invention relates to a switching / display device of the control technology, with at least one pair of contacts to the external device cable wires can be connected, wherein the pair of contacts within the device via a switch electrically connected to each other or electrically separated from each other or via a binary display element electrically connected to each other.
Derartige Schalt-/Anzeigegeräte sind allgemein bekannt. Sie weisen in der Regel je ein bis zwei Schalter und binäre Anzeigeelemente auf. Als Schalter kommen von Hand oder maschinell betätigte mechanische Schalter, Lichtschranken usw. in Frage, bei denen der eine Schaltzustand durch einen geschlossenen Schalter und der andere Schaltzustand durch einen geöffneten Schalter charakterisiert ist. Ebenso sind die beiden Anzeigezustände des binären Anzeigeelements durch Abgabe und Nichtabgabe eines Signals gekennzeichnet.Such switching / indicating devices are well known. As a rule, they each have one to two switches and binary display elements. As switch come by hand or mechanically operated mechanical switches, photocells, etc. in question, in which one switching state is characterized by a closed switch and the other switching state by an open switch. Likewise, the two display states of the binary display element are characterized by delivery and non-delivery of a signal.
Im Stand der Technik erfolgt in der Regel eine Einzelverdrahtung der Schalter bzw. Anzeigeelemente mit einer übergeordneten speicherprogrammierbaren Steuerung. Derartige Einzelverdrahtungen sind zeitaufwendig und fehlerträchtig.In the prior art, a single wiring of the switches or display elements is generally carried out with a higher-level programmable logic controller. Such individual wiring is time consuming and error prone.
Es ist auch schon bekannt, die Schalter- und/oder Anzeigeelemente eines Schalt-/Anzeigegeräts geräteintern über ein Flachbandkabel mit einem Busmodul zu verbinden und ein geräteexternes Buskabel an eine Busschnittstelle anzuschließen. Diese Lösung ist aber kostenintensiv.It is also already known to connect the switch and / or display elements of a switching / display device internally via a ribbon cable with a bus module and connect a device external bus cable to a bus interface. This solution is costly.
Schließlich ist noch bekannt, die Schalter und/oder Anzeigeelemente in großer Zahl auf einer großen Leiterplatte aufzulöten und so eine Schalttafel zu erstellen, von der aus über Steckverbindungen Signale mit einer speicherprogrammierbaren Steuerung austauschbar sind. Diese Lösung hat den Nachteil, daß sie starr und unflexibel ist.Finally, it is known to solder the switches and / or display elements in large numbers on a large circuit board and so to create a control panel, from which signals via plug-in connections with a programmable logic Control are interchangeable. This solution has the disadvantage that it is rigid and inflexible.
Aus der
Die Aufgabe der vorliegenden Erfindung besteht darin, eine schnelle und kostengünstige Verkabelungsmöglichkeit kleiner Schalt-/Anzeigegeräte mit einer speicherprogrammierbaren Steuerung zu schaffen.The object of the present invention is to provide a quick and inexpensive cabling option small switching / display devices with a programmable logic controller.
Die Aufgabe wird dadurch gelöst, daß das Paar von Kontakten in einer Steckeraufnahme angeordnet ist, in die ein Stecker einführbar ist, der aus mindestens zwei Steckerteilen besteht, die von einer Öffnungs- in eine Schließstellung überführbar sind, wobei die Kabeladern durch Einführen der Kabeladern mit ihren Aderisolierungen in den Stecker in der Öffnungsstellung und anschließendes Überführen des Steckers in die Schließstellung mit dem Stecker kontaktierbar sind.The object is achieved in that the pair of contacts is arranged in a connector receptacle into which a plug is inserted, which consists of at least two plug parts, which are convertible from an open position to a closed position, wherein the cable cores by inserting the cable cores with their wire insulation in the plug in the open position and subsequent transfer of the plug in the closed position with the plug are contacted.
Denn dadurch ist es möglich, daß die Schalter und/oder Anzeigeelemente geräteintern fest verdrahtet angeordnet sind, z. B. auf eine Leiterplatte aufgelötet, wohingegen der geräteexterne Anschluß über ein einziges Kabel erfolgen kann, das sehr schnell und einfach konfektionierbar ist.Because this makes it possible that the switches and / or display elements are internally wired hard wired, z. B. soldered onto a circuit board, whereas the device external connection can be made via a single cable that is very quick and easy to assemble.
Als Steckeraufnahmen kommen insbesondere eine Steckeraufnahme für einen FCC68-Datenstecker, einen Flachbandkabelstecker und einen Sub-D-Stecker in Frage. Insbesondere der FCC68-Datenstecker (sog. Westernstecker) ist sehr kostengünstig verfügbar. Darüber hinaus bietet er den Vorteil, daß er in der Steckeraufnahme verrastet fixiert ist.In particular, a plug receptacle for an FCC68 data plug, a ribbon cable plug and a sub-D plug come into consideration as plug receptacles. In particular, the FCC68 data connector (so-called Western plug) is available at very low cost. In addition, it offers the advantage that it is fixed in the connector receptacle locked.
Das Schalt-/Anzeigegerät bietet einen guten Kompromiß zwischen Größe und Artenvielfalt, wenn die Steckeraufnahme als Steckeraufnahme für zwei bis fünf Paare für Kontakten ausgebildet ist.The switch / indicator provides a good compromise between size and biodiversity when the plug receptacle is formed as a receptacle for two to five pairs of contacts.
Wenn mindestens ein Paar von Kontakten über einen Schalter elektrisch miteinander verbindbar bzw. elektrisch voneinander trennbar ist und mindestens ein Paar von Kontakten über ein binäres Anzeigeelement elektrisch miteinander verbunden ist, ergibt sich ein noch besserer Kompromiß.When at least one pair of contacts via a switch electrically connectable to each other or electrically from each other is separable and at least one pair of contacts via a binary display element is electrically connected to each other, there is an even better compromise.
Der Kompromiß ist optimal, wenn das Schalt-/Anzeigegerät drei Paare von Kontakten aufweist, zwei Paare von Kontakten über Schalter elektrisch miteinander verbindbar bzw. elektrisch voneinander trennbar sind und ein Paar von Kontakten über ein binäres Anzeigeelement elektrisch miteinander verbunden ist.The compromise is optimal when the switch / indicator has three pairs of contacts, two pairs of contacts are electrically connectable to each other via switches, and a pair of contacts are electrically connected to each other via a binary indicator.
Steuerungsseitig ist es möglich, eine konventionelle Einzelverdrahtung vorzunehmen. Vorzugsweise aber erfolgt die Verdrahtung über eine Adapterplatte mit mehreren Steckeraufnahmen, in die je ein Stecker einführbar ist, der aus mindestens zwei Steckerteilen besteht, die von einer Öffnungs- in eine Schließstellung überführbar sind, wobei die Kabeladern durch Einführen der Kabeladern mit ihren Aderisolierungen in den Stecker in der Öffnungsstellung und anschließendes Überführen des Steckers in die Schließstellung mit dem Stecker kontaktierbar sind, wobei die Steckeraufnahmen mit einer auf der Adapterplatte angeordneten Busschnittstelle verbunden sind.On the control side it is possible to carry out a conventional single wiring. Preferably, however, the wiring via an adapter plate with a plurality of plug receptacles, in each of which a plug is inserted, which consists of at least two plug parts, which can be transferred from an opening to a closed position, wherein the cable wires by inserting the cable wires with their wire insulation in the Plug in the open position and subsequent transfer of the plug in the closed position can be contacted with the plug, wherein the plug receptacles are connected to a arranged on the adapter plate bus interface.
Wenn die Busschnittstelle als serielle Busschnittstelle ausgebildet ist, ist die Weiterverkabelung zur speicherprogrammierbaren Steuerung mit besonders wenig Kabeladern erreichbar.If the bus interface is designed as a serial bus interface, the further wiring to the programmable logic controller can be achieved with particularly few cable cores.

Die Kabelisolierungen müssen nicht entfernt werden. Die Kabeladern 16 werden dann mit ihren Aderisolierungen in den in der Öffnungsstellung befindlichen Stecker 14 eingeführt. Sodann wird der Stecker 14 in seine Schließstellung überführt. Dadurch erfolgt ein automatisches und zwangsweises Kontaktieren der Kabeladern 16 mit dem Stecker 14.To contact the
Gemäß Ausführungsbeispiel ist der Stecker 14 als FCC68-Datenstecker und die Steckeraufnahme 13 für einen FCC68-Datenstecker demzufolge als korrespondierende Steckeraufnahme ausgebildet.
