Der Elektronikteil ist hinsichtlich der Ausgestaltung der elektrischen Anschlussmittel in aller Regel anwenderspezifisch konstruiert. In Abhängigkeit vom Bedarf des jeweiligen Anwenders sind daher die Anschlussmittel von Fall zu Fall beispielsweise als Rundstecker mit unterschiedlichen Durchmessern, als Flachstecker, oder mit einer sonstigen geeigneten Anschlusstechnik ausgeführt. Dies führt zu hohen Herstellungs- und Lagerhaltungskosten, da eine Vielzahl von Varianten des Elektronikteils bereitgestellt werden muss.The electronic part is usually designed user-specific in terms of the design of the electrical connection means. Depending on the needs of the respective user, therefore, the connection means are designed on a case-by-case basis, for example, as circular connectors with different diameters, as flat connectors, or with any other suitable connection technology. This leads to high manufacturing and storage costs, since a variety of variants of the electronic part must be provided.

Während die Ausgestaltung der zweiten elektrischen Schnittstellenmittel standardisiert ist, d.h. zur Kontaktierung unterschiedlicher Adapter geeignet ist, sind an den Steckadaptern typabhängig unterschiedlich gestaltete erste elektrische Schnittstellenmittel vorgesehen.From the US-A-5 501 608 shows a computer system having the features cited in the introduction, which has at least one receptacle in which second electrical interface means connected to an internal electronic unit are provided. Optionally, different plug-in adapters which have first electrical interface means that can be contacted by the second electrical interface means can be inserted into the receptacle. While the configuration of the second electrical interface means is standardized, ie, is suitable for contacting different adapters, the plug adapters are type-dependent provided differently shaped first electrical interface means.

Es ist die Aufgabe der vorliegenden Erfindung, ein Elektronikteil der eingangs genannten Art sowie eine damit ausgestattete Steuereinrichtung zu schaffen, dessen bzw. deren elektrische Anschlusstechnik so ausgeführt ist, dass den Kundenwünschen mit geringerem Aufwand Rechnung getragen werden kann.It is the object of the present invention to provide an electronic part of the aforementioned type and a control device equipped therewith, whose or their electrical connection technology is designed so that the customer's wishes can be met with less effort.

Zur Lösung dieser Aufgabe ist bei einem Elektronikteil der eingangs genannten Art vorgesehen, dass die sich in ihrer Ausgestaltung voneinander unterscheidenden Anschlussmittel mehrerer Adapter Ausgänge und/oder Eingänge für Sensoren und/oder elektrische Aktoren bilden, wobei die ersten elektrischen Schnittstellenmittel dieser Adapter ebenfalls standardisiert sind.To solve this problem, it is provided in an electronic part of the type mentioned that form in their design mutually different connection means of several adapters outputs and / or inputs for sensors and / or electrical actuators, wherein the first electrical interface means of these adapters are also standardized.

Die Aufgabe wird außerdem gelöst durch eine Steuereinrichtung, bei der das Elektronikteil mit einem elektronischen Steuerteil verdrahtet ist, das eine Steuerelektronik aufweist, die zur Versorgung der Ventilantriebe eines Ventilteils mit Steuersignalen dient.The object is also achieved by a control device in which the electronic part is wired to an electronic control part having an electronic control unit which serves to supply the valve actuators of a valve member with control signals.

Auf diese Weise erfolgt innerhalb des Elektronikteils eine Auftrennung von elektrischer Funktion und Anschlusstechnik, wobei die miteinander kooperierenden ersten und zweiten elektrischen Schnittstellenmittel die lösbare Schnittstelle zwischen den beiden Komponenten darstellen. Die elektrische bzw. elektronische Funktion, beispielsweise gewisse Steuerungsvorgaben und/oder elektronische Speichermaßnahmen, die unabhängig von der gewählten Anschlusstechnik ist und diesbezüglich keinen Anpassungen bedarf, verbleibt als Bestandteil der internen Elektronikeinheit in der Basis des Elektronikteils. Die individuell gewünschte Anschlusstechnik ist an einem Adapter vorgesehen, der sich an einem dafür vorgesehenen Bestückungsplatz an der Basis montieren lässt, wobei die Möglichkeit besteht, hinsichtlich ihrer Anschlusstechnik unterschiedlich ausgeführte Adapter wahlweise an ein und demselben Bestückungsplatz anzubringen. Um unterschiedlichen Kundenwünschen Rechnung zu tragen, ist das Elektronikteil mithin nur mit dem entsprechenden Adapter auszustatten, dessen Anschlussmittel den gewünschten Vorgaben entsprechen. Ein derartiges modulares Konzept ermöglicht es auch, auf wechselnden Sückzahlbedarf rasch reagieren zu können, da eine mit den kostenaufwendigen elektronischen Bauteilen ausgestattete Basis in einheitlicher Bauform für alle Anwendungsfälle zur Verfügung gestellt werden kann, die dann nur noch anwendungsspezifisch mit einem oder mehreren, die gewünschten Anschlussmittel aufweisenden Adaptern ausgerüstet werden muss. Auch hat der Anwender die Möglichkeit, nachträgliche Änderungen an der Anschlusstechnik vornehmen zu können, ohne den Elektronikteil komplett austauschen zu müssen. Die elektrischen Anschlussmittel bilden elektrische Ausgänge und/oder Eingänge, die das Anschließen von Sensoren und/oder von Aktoren ermöglichen.In this way, a separation of electrical function and connection technology takes place within the electronic part, wherein the cooperating first and second electrical interface means represent the detachable interface between the two components. The electrical or electronic function, for example certain control specifications and / or electronic storage measures, which is independent of the chosen connection technology and requires no adjustments in this regard, remains as part of the internal electronics unit in the base of the electronic part. The individually desired connection technology is provided on an adapter, which can be mounted at a designated mounting position on the base, with the possibility exists, with regard to their connection technology differently designed adapters either at one and the same placement place. In order to accommodate different customer requirements, the electronics part is therefore only equipped with the appropriate adapter whose connection means meet the desired specifications. Such a modular concept also makes it possible to respond quickly to changing Sückzahlbedarf, as equipped with the costly electronic components base in a uniform design for all applications can be made available, the then only application-specific with one or more, the desired connection means equipped with adapters. The user also has the option of making subsequent changes to the connection technology without having to replace the electronics part completely. The electrical connection means form electrical outputs and / or inputs, which allow the connection of sensors and / or actuators.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous developments of the invention will become apparent from the dependent claims.

Das Elektronikteil kann dahingehend modular aufgebaut sein, dass es über mehrere aneinandergesetzte Elektronikmodule verfügt, die jeweils mit mindestens einem Adapter und einer zugehörigen internen Elektronikeinheit ausgestattet sind.The electronic part may be constructed to be modular in that it has a plurality of juxtaposed electronic modules, which are each equipped with at least one adapter and an associated internal electronics unit.

Der Adapter weist zweckmäßigerweise ein Adaptergehäuse auf, in dem ein Kontaktmittelträger angeordnet ist, der sowohl die ersten elektrischen Schnittstellenmittel als auch die elektrischen Kontaktmittel der zugeordneten elektrischen Anschlussmittel trägt. Dies ermöglicht eine getrennte Fertigung der rein mechanischen Zwecken und der elektrischen Zwecken dienenden Komponenten des Adapters. Dabei kann insbesondere vorgesehen sein, dass die elektrischen Anschlussmittel über mechanische Befestigungsmittel verfügen, die die mechanische Fixierung der anzuschließenden weiterführenden elektrischen Leiter ermöglichen und die als Bestandteil des Adaptergehäuses ausgeführt sind, wobei insbesondere eine integrale Bauweise der mechanischen Befestigungsmittel und des Adaptergehäuses vorgesehen sein kann.The adapter expediently has an adapter housing, in which a contact means carrier is arranged, which carries both the first electrical interface means and the electrical contact means of the associated electrical connection means. This allows separate production of purely mechanical purposes and the electrical components of the adapter components. It can in particular be provided that the electrical connection means have mechanical fastening means which allow the mechanical fixing of the connected further electrical conductors and which are designed as part of the adapter housing, in particular an integral construction of the mechanical fastening means and the adapter housing may be provided.

Der Kontaktmittelträger ist vorzugsweise plattenartig ausgeführt und kann insbesondere von einer mit den Kontaktmitteln und mit den ersten elektrischen Schnittstellenmitteln bestückten Leiterplatte gebildet sein.The contact means carrier is preferably designed plate-like and may be formed in particular by a equipped with the contact means and with the first electrical interface means printed circuit board.

Eine besonders kompakte Anordnung ergibt sich, wenn der Adapter als Deckel der Basis ausgeführt ist, so dass bei entferntem Adapter am zugeordneten Bestückungsplatz eine den Zugang zur internen Elektronikeinheit ermöglichende Zugangsöffnung der Basis freigelegt ist.A particularly compact arrangement results when the adapter is designed as a cover of the base, so that when the adapter is removed at the associated placement space an access to the internal electronics unit enabling access opening of the base is exposed.

Die die elektrische Verbindung mit dem Adapter bewirkenden zweiten elektrischen Schnittstellenmittel sind zweckmäßigerweise unmittelbar an der internen Elektronikeinheit vorgesehen und können somit unmittelbar bei deren Fertigung angebracht werden.The electrical connection to the adapter causing the second electrical interface means are expediently provided directly to the internal electronics unit and can thus be mounted directly during their production.

Die interne Elektronikeinheit ist zweckmäßigerweise in einem Gehäusehauptkörper des Elektronikteils untergebracht, der zusammen mit dem als Deckel ausgeführten Adapter das Gehäuse des Elektronikteils bilden kann.The internal electronics unit is conveniently housed in a housing main body of the electronic part, which together can form the housing of the electronic part with the adapter designed as a lid.

Die interne Elektronikeinheit ist zweckmäßigerweise auf einer Leiterplatte ausgeführt und lässt sich somit sehr einfach herstellen und in der Basis installieren.The internal electronics unit is expediently designed on a printed circuit board and can thus be very easily manufactured and installed in the base.

Im Zusammenhang mit der modularen Anschlusstechnik ist es von Vorteil, wenn eventuell vorhandene optische Anzeigemittel und/oder Markierungen, die beispielsweise den Betätigungszustand der internen Elektronikeinheit wiedergeben, nicht am Adapter, sondern an der Elektronikeinheit vorgesehen sind. Sie werden in diesem Falle von einem Austausch des Adapters nicht berührt. Um gleichwohl die optischen Anzeigen und/oder die Markierungen für einen Betrachter von außen her gut sichtbar zu machen, ist der Adapter zweckmäßigerweise zumindest teilweise und vorzugsweise zur Gänze durchsichtig.ausgeführt, besteht also insoweit aus transparentem Material, und ermöglicht somit eine bequeme Sichtbarmachung der optischen Anzeigen und/oder der Markierungen. In diesem Zusammenhang kann vorgesehen sein, die Markierungen an einem insbesondere auswechselbaren Markierungsträger der internen Elektronikeinheit vorzusehen, der über Lichtleitkanäle verfügen kann, durch die hindurch von den optischen Anzeigemitteln hervorgerufene Lichtsignale zu einem durchsichtigen Bereich des Adapters gelangen können.In connection with the modular connection technology, it is advantageous if any existing optical display means and / or markers, which reproduce, for example, the operating state of the internal electronics unit, are not provided on the adapter, but on the electronic unit. You will not be affected in this case by an exchange of the adapter. Nevertheless, in order to make the visual displays and / or the markings easily visible to a viewer from the outside, the adapter is expediently at least partially and preferably completely transparent. It thus consists of transparent material, and thus makes possible a comfortable visualization of the optical Ads and / or markers. In this context, it may be provided to provide the markings on a particular interchangeable marking carrier of the internal electronic unit, which may have light guide channels through which light signals caused by the optical display means can pass to a transparent region of the adapter.

Die Figur 1 zeigt eine allgemein mit Bezugsziffer 1 bezeichnete Steuereinrichtung, die im Zusammenhang mit der gesteuerten Betätigung beliebiger Aktoren einsetzbar ist, bei denen es sich um durch Fluidkraft und/oder elektrisch betätigte Aktoren handeln kann.1 shows a generally designated by reference numeral 1 control device which can be used in connection with the controlled operation of any actuators, which may be by fluid power and / or electrically actuated actuators.

Die Steuereinrichtung 1 enthält beim Ausführungsbeispiel einen Ventilteil 2, der über mehrere batterieartig zusammengefasste Ventile 3 verfügt, deren Betätigung durch elektrische Signale hervorgerufen wird. Sie enthalten nicht näher dargestellte, elektrisch betätigbare Ventilantriebe, beispielsweise Elektromagnete oder Piezoantriebe. In Abhängigkeit von der vorgegebenen Schaltstellung eines jeweiligen Ventils 3 erfolgt die Betätigung nicht dargestellter angeschlossener Verbraucher, bei denen es sich beispielsweise um fluidbetriebene Antriebe handelt. Bei 4 sind Anschlussöffnungen gezeigt, über die das zu verteilende Druckmedium eingespeist und abgeführt wird und an die sich Fluidleitungen anschließen lassen, die zu den zu versorgenden Verbrauchern führen.In the exemplary embodiment, the control device 1 contains a valve part 2 which has a plurality of battery-like combined valves 3 whose actuation is caused by electrical signals. They contain not shown in detail, electrically actuated valve actuators, such as electromagnets or piezo drives. Depending on the predetermined switching position of a respective valve 3, the operation is not shown connected Consumers, which are, for example, fluid-operated drives. At 4 port openings are shown, via which the pressure medium to be distributed is fed and discharged and can connect to the fluid lines leading to the consumers to be supplied.

Ein elektronisches Steuerteil 5 der Steuereinrichtung 1 enthält eine Steuerelektronik, über die die Ventilantriebe des Ventilteils 2 in der gewünschten Weise mit Steuersignalen versorgt werden. Das elektronische Steuerteil 5 enthält zweckmäßigerweise eine Feldbuseinheit 10, über die eine Datenkommunikation mit einer übergeordneten Steuerung und/oder mit anderen Steuereinrichtungen stattfinden kann. Ferner kann das Steuerteil bei Bedarf mit einem eigenen, individuell programmierbaren Steuerprogramm ausgestattet sein.An electronic control part 5 of the control device 1 contains control electronics, via which the valve drives of the valve part 2 are supplied in the desired manner with control signals. The electronic control part 5 expediently contains a field bus unit 10, via which data communication with a higher-level control and / or with other control devices can take place. Furthermore, the control part can be equipped with its own, individually programmable control program if required.

Eine weitere Komponente der Steuereinrichtung 1 wird von dem erfindungsgemäßen Elektronikteil 6 repräsentiert. Dieses ist intern mit dem elektronischen Steuerteil 5 verdrahtet und enthält an seiner Außenfläche eine Mehrzahl von außen her zugänglicher elektrischer Anschlussmittel 7, die das Anschlie-ßen zumindest eines und vorzugsweise mehrerer weiterführender elektrischer Leiter ermöglichen, die in der Zeichnung nicht näher dargestellt sind. Die elektrischen Leiter sind in der Regel als Bestandteile von flexiblen Kabeln ausgestaltet und ermöglichen beispielsweise das elektrische Anschließen von Sensoren oder von elektrischen Aktoren wie Magnetventile oder Relais. Beim Ausführungsbeispiel bilden die elektrischen Anschlussmittel 7 dementsprechend Ausgänge und/oder Eingänge für elektrische Signale, wobei über die elektrischen Anschlussmittel durchaus auch beliebige Steuersignale in der einen oder anderen Richtung versandt werden können.Another component of the control device 1 is represented by the electronic part 6 according to the invention. This is internally wired to the electronic control part 5 and contains on its outer surface a plurality of externally accessible electrical connection means 7, which allow the connecting at least one and preferably several further electrical conductors, which are not shown in detail in the drawing. The electrical conductors are usually designed as components of flexible cables and allow, for example, the electrical connection of sensors or electrical actuators such as solenoid valves or relays. In the embodiment form the electrical connection means Accordingly, outputs and / or inputs for electrical signals, which can be sent via the electrical connection means quite any control signals in one or the other direction.

Die elektrischen Anschlussmittel 7 sind beim Ausführungsbeispiel als Bestandteile zweier Adapter 8 ausgebildet, die jeweils auswechselbar an einem dafür vorgesehenen Bestückungsplatz 11 einer Basis 12 des Elektronikteils 6 lösbar angebracht sind. Jedem Adapter 8 ist eine im Innern der Basis 12 plazierte interne Elektronikeinheit 13 zugeordnet, wobei zweckmäßigerweise jeder Adapter 8 über eine eigene Elektronikeinheit 13 verfügt. Jede Elektronikeinheit 13 steht mit den elektrischen Anschlussmitteln 7 des ihr zugeordneten Adapters 8 in elektrischer Verbindung.The electrical connection means 7 are formed in the embodiment as components of two adapters 8, which are each removably attached to a designated placement space 11 of a base 12 of the electronic part 6 releasably attached. Each adapter 8 is assigned an internal electronic unit 13 placed inside the base 12, wherein expediently each adapter 8 has its own electronic unit 13. Each electronic unit 13 is in electrical connection with the electrical connection means 7 of the associated adapter 8.

Die Elektronikeinheit 13 beinhaltet zweckmäßigerweise eine mit elektronischen Bauteilen bestückte Leiterplatte 14 und ist in einem zumindest partiell hohl ausgeführten Gehäusehauptkörper 15 des Elektronikteils 6 untergebracht. Sie ist dort durch geeignete Befestigungsmittel 16 fest verankert, wobei aber eine einen Austausch ermöglichende lösbare Befestigungsart vorgesehen sein kann.The electronic unit 13 expediently contains a printed circuit board 14 equipped with electronic components and is accommodated in an at least partially hollow casing main body 15 of the electronic component 6. It is firmly anchored there by suitable fasteners 16, but it can be provided an exchange enabling releasable fastening.

Die elektrische Verbindung zwischen der Elektronikeinheit 13 und den elektrischen Anschlussmitteln 7 des jeweils zugeordneten Adapters 8 erfolgt über miteinander korrespondierende erste und zweite Schnittstellenmittel 17, 18, die zum einen am Adapter 8 und zum anderen an der Elektronikeinheit 13 vorgesehen sind. Während die vorzugsweise unmittelbar an der Leiterplatte 14 vorgesehenen zweiten Schnittstellenmittel 18 mit den Elektronikbauteilen der Elektronikeinheit 13 verbunden sind, stehen die ersten Schnittstellenmittel 17 innerhalb des Adapters 8 über elektrische Leiter 9 mit dessen elektrischen Anschlussmitteln 7 in Verbindung.The electrical connection between the electronic unit 13 and the electrical connection means 7 of the respective associated adapter 8 via mutually corresponding first and second interface means 17, 18, the one are provided on the adapter 8 and on the other to the electronic unit 13. While the second interface means 18, which are preferably provided directly on the printed circuit board 14, are connected to the electronic components of the electronic unit 13, the first interface means 17 are connected within the adapter 8 via electrical conductors 9 to its electrical connection means 7.

Während die elektrischen Anschlussmittel 7 der einzelnen Adapter 8 in ihrer konkreten Ausgestaltung und insbesondere in der konkret verwirklichten Anschlusstechnik voneinander abweichen können, sind die miteinander kooperierenden ersten und zweiten Schnittstellenmittel 17, 18 bei jeder Adapter-Elektronikeinheit-Paarung gleich ausgeführt und können daher als standardisierte Bauteile bezeichnet werden. Beim Ausführungsbeispiel sind sie von Steckmitteln gebildet, insbesondere in Form von ineinander einsteckbaren Steckerleisten. Wird ein Adapter 8 an einem der Bestückungsplätze 11 montiert, erfolgt beim Ansetzen unmittelbar die elektrische Kontaktierung der ersten und zweiten Schnittstellenmittel 17, 18. In vergleichbarer Weise wird diese elektrische Verbindung beim Entfernen eines Adapters 8 von der Basis 12 selbsttätig getrennt.While the electrical connection means 7 of the individual adapters 8 may differ from one another in their concrete configuration and in particular in the concrete connection technology implemented, the cooperating first and second interface means 17, 18 are identical in each adapter-electronics unit pairing and can therefore be considered as standardized components be designated. In the embodiment, they are formed by plug-in means, in particular in the form of plug-in connector strips. If an adapter 8 is mounted on one of the placement places 11, the electrical contacting of the first and second interface means 17, 18 takes place directly during attachment. In a comparable manner, this electrical connection is automatically separated from the base 12 when an adapter 8 is removed.

In den Elektronikeinheiten 13 sind die vom Elektronikteil 6 auszuführenden elektrischen bzw. elektronischen Funktionen zusammengefasst. Die Adapter 8 beinhalten lediglich die Anschlusstechnik, die benötigt wird, um nach bestimmten mechanischen Vorgaben den elektrischen Anschluss der weiterführenden externen Leiter zu ermöglichen. Im Zusammenhang damit, dass von den Anwendern der Steuereinrichtung 1 individuell unterschiedlich ausgestaltete elektrische Anschlussmittel 7 benötigt werden - bedingt durch anwenderseitig bereits vorhandene elektrische Installationen -, bietet die erfindungsgemäße Ausgestaltung des Elektronikteils 6 die Möglichkeit, die Basis 12 an jedem einzelnen Bestückungsplatz 11 wahlweise mit unterschiedlichen Adaptern 8 auszurüsten, die über voneinander abweichend gestaltete elektrische Anschlussmittel 7 verfügen. Man hat also die Möglichkeit, das Elektronikteil 6 individuell nach Kundenwunsch mit nur geringem Aufwand mit der benötigten Anschlusstechnik auszurüsten.In the electronic units 13, the electronic or electronic functions to be executed by the electronic part 6 are summarized. The adapters 8 contain only the connection technique required to operate according to specific mechanical conditions Specifications to allow the electrical connection of the secondary external conductors. In connection with the fact that the user of the control device 1 individually differently designed electrical connection means 7 are required - due to existing already existing electrical installations - the inventive design of the electronic part 6 offers the possibility of the base 12 at each assembly station 11 optionally with different To equip adapters 8, which have different from each other designed electrical connection means 7. So you have the opportunity to customize the electronic part 6 according to customer requirements with little effort with the required connection technology.

Zugunsten einer kompakten Bauform sind die Adapter 8 beim Ausführungsbeispiel so ausgebildet, dass sie einen Deckel 23 der Basis 12 bilden. Der Gehäusehauptkörper 15 ist im Bereich der Bestückungsplätze 11 jeweils mit einer Zugangsöffnung 24 versehen, die bei entferntem Adapter 8 freigelegt ist und zweckmäßigerweise einen Zugang zu der im Innern des Gehäusehauptkörpers 15 untergebrachten internen Elektronikeinheit 13 ermöglicht. Ist der Adapter 8 installiert, deckt er die Zugangsöffnung 24 ab, und zwar vorzugsweise unter Abdichtung, so dass ein ringsum dicht geschlossenes Gehäuse des Elektronikteils 6 vorliegt.For the sake of a compact design, the adapters 8 in the exemplary embodiment are designed such that they form a cover 23 of the base 12. The housing main body 15 is provided in the region of the placement slots 11 each with an access opening 24 which is exposed with the adapter 8 removed and expediently allows access to the inside of the housing main body 15 accommodated internal electronic unit 13. If the adapter 8 is installed, it covers the access opening 24, preferably under sealing, so that there is a tightly sealed housing of the electronic part 6 all around.

Ein jeweiliger Adapter 8 verfügt zweckmäßigerweise über ein beim Ausführungsbeispiel kastenähnlich gestaltetes Adaptergehäuse 22, das über eine offene Unterseite 25 verfügt, die im montierten Zustand dem Bestückungsplatz 11 zugewandt ist. Im Innern des Adaptergehäuses 22 befindet sich ein Kontaktmittelträger 26, der zweckmäßigerweise plattenartig ausgeführt ist und insbesondere von einer in geeigneter Weise bestückten Leiterplatte gebildet wird. Er trägt zum einen die ersten elektrischen Schnittstellenmittel 17 und zum anderen die elektrischen Kontaktmittel 27 der elektrischen Anschlussmittel 7. Ferner verfügt er über elektrische Leiter 9, vorzugsweise in Gestalt von Leiterbahnen, die die ersten Schnittstellenmittel 17 mit den elektrischen Kontaktmitteln 27 zuordnungsrichtig elektrisch verbinden.A respective adapter 8 has expediently a box-like designed in the embodiment adapter housing 22, which has an open bottom 25, which faces the assembly space 11 in the assembled state. In the interior of the adapter housing 22 there is a contact means carrier 26, which is expediently plate-like and in particular is formed by a suitably equipped printed circuit board. It carries on the one hand the first electrical interface means 17 and on the other hand, the electrical contact means 27 of the electrical connection means 7. Furthermore, it has electrical conductors 9, preferably in the form of conductor tracks, which electrically connect the first interface means 17 to the electrical contact means 27.

Die elektrischen Anschlussmittel 7 sind zweckmäßigerweise mit mechanischen Befestigungsmitteln 28 ausgestattet, die die mechanische Fixierung der anzuschließenden weiterführenden elektrischen Leiter ermöglichen. Die Befestigungsmittel 28 können beispielsweise einfache Steckfortsätze oder Schraubgewinde oder Bajonettverbindungsmittel sein. Obgleich es prinzipiell möglich wäre, die mechanischen Befestigungsmittel 28 als separate Teile am Adaptergehäuse 22 anzubringen, empfiehlt sich die beim Ausführungsbeispiel realisierte Bauform einer einstückigen Verbindung zwischen den Befestigungsmitteln 28 und dem Adaptergehäuse 22. Es ist auf diese Weise eine einheitliche und kostengünstige Herstellung möglich, beispielsweise durch Spritzgießen.The electrical connection means 7 are expediently equipped with mechanical fastening means 28, which allow the mechanical fixation of the connected electrical conductors to be connected. The fastening means 28 may be, for example, simple plug-in extensions or screw thread or bayonet connection means. Although it would be possible in principle to attach the mechanical fasteners 28 as separate parts on the adapter housing 22, the embodiment realized in the embodiment of a one-piece connection between the fastening means 28 and the adapter housing 22 is recommended. It is possible in this way a uniform and cost-effective production, for example by injection molding.

Der Kontaktmittelträger 26 und das Adaptergehäuse 22 sind ursprünglich getrennte Bauteile, die unter Bildung des Adapters 8 vereinigt werden. Hierzu wird beim Ausführungsbeispiel der plattenartige Kontaktmittelträger 26 über die offene Unterseite 25 hinweg in das Adaptergehäuse 22 eingesetzt, wobei sich die elektrischen Kontaktmittel 27 mit den mechanischen Befestigungsmitteln 28 zu den elektrischen Anschlussmitteln 7 vereinigen. Beim Ausführungsbeispiel verfügen hierzu die mechanischen Befestigungsmittel 28 über jeweils einen nach außen ragenden Vorsprung, der mit einer oder mehreren Durchbrechungen versehen ist, durch die stiftartige elektrische Kontaktmittel 27 beim Einsetzen des Kontaktmittelträgers 26 hindurchgreifen. Der Kontaktmittelträger 26 wird durch geeignete Haltemittel 32 im Adaptergehäuse 22 fixiert, beispielsweise durch Rastverbindung.The contact means carrier 26 and the adapter housing 22 are originally separate components, which are combined to form the adapter 8. For this purpose, in the embodiment of the plate-like contact means carrier 26 is inserted over the open bottom 25 away in the adapter housing 22, wherein the electrical contact means 27 unite with the mechanical fastening means 28 to the electrical connection means 7. In the embodiment, for this purpose, the mechanical fastening means 28 each have an outwardly projecting projection which is provided with one or more apertures, reach through the pin-like electrical contact means 27 during insertion of the contact means carrier 26. The contact means carrier 26 is fixed by suitable holding means 32 in the adapter housing 22, for example by latching connection.

Es versteht sich, dass die elektrischen Kontaktmittel 27 und die mechanischen Befestigungsmittel 28 alternativ auch an einem einheitlichen Adapterkörper vorgesehen sein können. Die mehrteilige Bauform hat allerdings fertigungstechnische Vorteile.It is understood that the electrical contact means 27 and the mechanical fastening means 28 can alternatively also be provided on a unitary adapter body. However, the multi-part design has manufacturing advantages.

Bei montiertem Adapter 8 verlaufen beim Ausführungsbeispiel der Kontaktmittelträger 26 und die Leiterplatte 14 der zugeordneten Elektronikeinheit 23 zweckmäßigerweise in zueinander parallelen Ebenen, so dass man von einem Schichtaufbau sprechen kann, der ausweislich der Figur 3 sehr kompakte Höhenabmessungen zulässt.When mounted adapter 8 extend in the embodiment of the contact means carrier 26 and the circuit board 14 of the associated electronics unit 23 expediently in mutually parallel planes, so that one can speak of a layer structure that allows evidenced by Figure 3 very compact height dimensions.

Wie aus Figur 1 hervorgeht, kann der Adapter 8 versenkt in der Basis untergebracht sein, so dass sich keine störend überstehenden Teile ergeben und eine weitere Voraussetzung für einen kompakten Aufbau gegeben ist.As is apparent from Figure 1, the adapter 8 can be housed sunk in the base, so that there are no disturbing protruding parts and another prerequisite for a compact design is given.

Beim Ausführungsbeispiel der Figur 1 ist das Elektronikteil 6 modular auch insofern aufgebaut, als es sich aus mehreren lösbar aneinandergesetzten Elektronikmodulen 32 zusammensetzt. Jedes dieser Elektronikmodule 32 beinhaltet eine interne Elektronikeinheit 13 und einen zugeordneten Adapter 8. Je nach Bedarf können mehrere derartige Elektronikmodule 32 aneinandergereiht werden, um die Steuereinrichtung 1 beliebig zu erweitern.In the embodiment of Figure 1, the electronic part 6 is also modular in so far as it is composed of several releasably juxtaposed electronic modules 32. Each of these electronic modules 32 includes an internal electronics unit 13 and an associated adapter 8. Depending on requirements, a plurality of such electronic modules 32 can be strung together to expand the control device 1 arbitrarily.

Es sei darauf hingewiesen, dass das Elektronikteil 6 durchaus über nur einen einzigen Adapter 8 verfügen kann, der mit der momentan gewünschten Anschlusstechnik ausgestattet ist. Ein und derselbe Bestückungsplatz kann hier wahlweise mit unterschiedlichen Adaptern ausgestattet werden.It should be noted that the electronic part 6 may well have only a single adapter 8, which is equipped with the currently desired connection technology. One and the same placement space can be equipped with different adapters.

Zur lösbaren und auswechselbaren Befestigung des Adapters 8 an der Basis 12 sind beim Ausführungsbeispiel Befestigungsmittel 33 in Gestalt von Schraubverbindungsmitteln vorgesehen. Allerdings sind auch andere Bauformen denkbar, beispielsweise eine Fixierung durch Rastverbindungsmittel.For detachable and replaceable attachment of the adapter 8 to the base 12 fastening means 33 are provided in the form of screw connection means in the embodiment. However, other designs are conceivable, for example, a fixation by locking connection means.

Das Elektronikteil 6 ist mit optischen Anzeigemitteln 34 ausgestattet, die optische Signale abgeben können, welche gewisse Betätigungszustände anzeigen. So kann beispielsweise die Anzeige bestimmter Betätigungszustände angeschlossener Sensoren oder Aktoren erfolgen. Zweckmäßigerweise sind die optischen Anzeigemittel 34 als Leuchtmittel ausgeführt, beispielsweise in Gestalt von LED's.The electronic part 6 is provided with optical display means 34 which can emit optical signals indicating certain states of actuation. For example, the display of certain states of actuation of connected sensors or actuators can take place. Conveniently, the optical display means 34 are designed as bulbs, for example in the form of LEDs.

Des weiteren verfügt der Elektronikteil 6 über Markierungen 35, insbesondere in Gestalt von Beschriftungen, die den optischen Anzeigemitteln 34 zugeordnet sind und die es einem Betrachter ermöglichen, die Bedeutung eines optischen Signals leicht festzustellen.Furthermore, the electronic part 6 has marks 35, in particular in the form of labels, which are associated with the optical display means 34 and allow a viewer to easily determine the importance of an optical signal.

Vorteilhafterweise sind sowohl die optischen Anzeigemittel 34 als auch die Markierungen 35 an der internen Elektronikeinheit vorgesehen, die unabhängig vom jeweils verwendeten Adapter 8 an Ort und Stelle verbleibt. Dies hat den Vorteil, dass die Anzeige- und Markierungsmaßnahmen sich auf die Elektronikeinheit 13 beschränken, während die Vielzahl eventuell zur Verfügung gestellter Adapter 8 selbst nicht mit Anzeigemitteln oder gar Markierungen ausgestattet werden müssen.Advantageously, both the optical display means 34 and the marks 35 are provided on the internal electronics unit, which remains in place regardless of the adapter 8 used in each case. This has the advantage that the display and marking measures are limited to the electronic unit 13, while the large number of possibly provided adapter 8 itself need not be equipped with display means or even markings.

Beim Ausführungsbeispiel befinden sich die optischen Anzeigemittel 34 an der dem Adapter 8 zugewandten Oberseite der Leiterplatte 14. Um die optischen Signale für einen Außenstehenden sichtbar zu machen, ist das Adaptergehäuse 22 zumindest in dem den optischen Anzeigemitteln 34 gegenüberliegenden Bereich durchsichtig ausgebildet und besteht dort insbesondere aus transparentem Kunststoffmaterial. Zugunsten einer einfachen Herstellung ist zweckmäßigerweise das gesamte Adaptergehäuse 32 transparent ausgeführt.In the exemplary embodiment, the optical display means 34 are located on the upper side of the printed circuit board 14 facing the adapter 8. In order to make the optical signals visible to an outsider, the adapter housing 22 is at least in the region opposite the optical display means 34 formed transparent and consists there in particular of transparent plastic material. For ease of manufacture, the entire adapter housing 32 is expediently made transparent.

Die Markierungen 35 können ebenfalls unmittelbar an der Leiterplatte 14 der Elektronikeinheit 13 vorgesehen sein. Sie können, wie die optischen Signale, von außen her durch das zumindest partiell durchsichtige Adaptergehäuse 22 hindurch visuell erfasst bzw. abgelesen werden.The markings 35 can likewise be provided directly on the printed circuit board 14 of the electronic unit 13. Like the optical signals, they can be visually detected or read from outside through the at least partially transparent adapter housing 22.

Ist allerdings die Leiterplatte 14 wie abgebildet mit einem größeren Abstand zu der ihr parallelen Gehäusewand 36 des Adaptergehäuses 32 angeordnet, empfiehlt sich die beim Ausführungsbeispiel realisierte Maßnahme des zusätzlichen Einbaus eines Markierungsträgers 37 zwischen die besagte Gehäusewand 36 und die Leiterplatte 14 der Elektronikeinheit 13. Dieser Markierungsträger 37 kann der Elektronikeinheit 13 zugerechnet werden und verbleibt bei dieser ungeachtet des Austausches eines Adapters 8. Er könnte fest mit der Leiterplatte. 14 verbunden sein, wobei sich aber aus Variabilitätsgründen eine auswechselbare Bauform empfiehlt.If, however, the printed circuit board 14 is arranged at a greater distance from its parallel housing wall 36 of the adapter housing 32, the measure of additional installation of a marking carrier 37 between said housing wall 36 and the printed circuit board 14 of the electronic unit 13 is recommended 37 may be attributed to the electronic unit 13 and remains in this regardless of the replacement of an adapter 8. It could be stuck to the circuit board. 14 be connected, but for reasons of variability recommends an interchangeable design.

Der Markierungsträger 37 besitzt eine mit den Markierungen 35 versehene Tragfläche 38, die bei montiertem Adapter 8 in dessen Innenraum in unmittelbarer Nähe zu der vorerwähnten Gehäusewand 36 zu liegen kommt. Die Markierungen 35 können daher durch die transparente Gehäusewand 36 hindurch sehr gut abgelesen werden.The marking carrier 37 has a bearing surface 38 provided with the markings 35, which, when the adapter 8 is mounted, comes to rest in the interior thereof in the immediate vicinity of the aforementioned housing wall 36. The marks 35 can therefore be read very well through the transparent housing wall 36 therethrough.

Zweckmäßigerweise verfügt der Markierungsträger 37 über einen oder mehrere Durchbrüche 42, durch die hindurch die ersten und zweiten Schnittstellenmittel 17, 18 problemlos kontaktiert werden können.Conveniently, the marker carrier 37 has one or more apertures 42 through which the first and second interface means 17, 18 can be easily contacted.

Um durch den Markierungsträger 37 eine Behinderung des Erkennens der durch die optischen Anzeigemittel 34 ausgegebenen Signale zu vermeiden, ist der Markierungsträger 37 beim Ausführungsbeispiel mit Lichtleitkanälen 43 versehen, die die im Bereich der Leiterplatte 14 erzeugten optischen Signale bis hin zur Tragfläche 38 leiten, so dass sie dort neben den Markierungen 35 erscheinen. Es versteht sich, dass der Markierungsträger 37 anstelle der Realisierung einzelner Lichtleitkanäle 43 auch vollständig transparent ausgebildet sein kann, zumindest in dem zwischen den optischen Anzeigemitteln 34 und der gegenüberliegenden Gehäusewand 36 des Adaptergehäuses 22 liegenden Abschnitt.In order to prevent the marking carrier 37 from obstructing the signals emitted by the optical display means 34, the marker carrier 37 in the exemplary embodiment is provided with light guide channels 43 which guide the optical signals generated in the area of the printed circuit board 14 all the way to the support surface 38, so that they appear there beside the marks 35. It is understood that the marking carrier 37 may be formed completely transparent instead of the realization of individual light guide channels 43, at least in the lying between the optical display means 34 and the opposite housing wall 36 of the adapter housing 22 section.

Eine weitere Möglichkeit zur Überbrückung des Abstandes zwischen den optischen Anzeigemitteln 34 und der gegenüberliegenden Gehäusewand 36 des Adaptergehäuses 32 besteht darin, am Adaptergehäuse 32 an der Innenfläche der vorgenannten Gehäusewand 36 Lichtleitvorsprünge vorzusehen, die insbesondere stiftartig ausgebildet sind und sich bis hin zu den optischen Anzeigemitteln 34 an der Leiterplatte 14 erstrecken. In Figur 3 ist exemplarisch ein solcher Lichtleitvorsprung strichpunktiert bei 44 angedeutet. Die Lichtleitvorsprünge 44 bestehen vorzugsweise aus lichtleitendem Material, beispielsweise aus transparentem Kunststoffmaterial, und leiten die von den optischen Anzeigemitteln emittierten Lichtsignale insbesondere punktuell zu einem durchsichtigen Bereich des Adaptergehäuses 32. Bevorzugt sind sie einstückig mit dem Adaptergehäuse 32 ausgebildet.Another possibility for bridging the distance between the optical display means 34 and the opposite housing wall 36 of the adapter housing 32 is to provide on the adapter housing 32 on the inner surface of the aforementioned housing wall 36 Lichtleitvorsprünge, which are formed in particular pin-like and down to the optical display means 34th extend on the circuit board 14. In FIG 3, such a Lichtleitvorsprung dash-dotted lines at 44 is an example. The Lichtleitvorsprünge 44 are preferably made of a light-conducting material, such as transparent plastic material, and direct the light emitted by the optical display means light signals in particular selectively to a transparent region of the adapter housing 32. Preferably, they are integrally formed with the adapter housing 32.

Die Lichtleitvorsprünge 44 können auch in Verbindung mit einem Markierungsträger 37 vorhanden sein. Dessen Lichtleitkanäle 43 können dabei von einfachen Durchbrechungen gebildet sein, in die die Lichtleitvorsprünge 44 hineinragen bzw. die von den Lichtleitvorsprüngen 44 durchsetzt werden.The Lichtleitvorsprünge 44 may also be present in conjunction with a marking carrier 37. Wherein Lichtleitkanäle 43 may be formed by simple openings, in which the Lichtleitvorsprünge 44 protrude or are penetrated by the Lichtleitvorsprüngen 44.
