The operating part includes a base (4) made of two components: an electroplatable plastics, and a non-electroplatable, insulating plastics. The first component forms integrated contact surfaces (5,6) in connection with at least one metal layer. The second component provides a mechanically robust structure and electrically insulates the base. A rocker (1) acts on an operating arm (3) which forms a switch with the contact surfaces.

Description

Die Erfindung bezieht sich auf ein Bedienelement eines elektrischen/elektronischen Installationsgerätes gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung kann beispielsweise bei elektronischen Unterputzgeräten, wie Dimmern und Jalousieschaltern verwendet werden.The invention relates to an operating element of an electrical / electronic installation device according to the preamble of claim 1. The invention can for example for electronic flush-mounted devices such as dimmers and blind switches be used.

Die zur Betätigung von Unterputzgeräten eingesetzten Bedienelemente bestehen zumeist aus einer Wippe und einem Sockel, die ineinander verrastet sind. Zwischen diesen meist aus Kunststoff hergestellten Teilen befindet sich eine zur Betätigung notwendige Elektronik in Form einer einseitig beschichteten Leiterplatte mit einfachem Layout. Die Leiterplatte kann mit elektronischen und/oder elektrischen Bauteilen, beispielsweise Widerständen bestückt sein. Als Schaltelemente können Mikrotaster, Elastomerschaltmatten oder Schaltbleche ("Knackfrosch") verwendet werden. Die Kontaktierung zwischen Bedienteil und Unterputzgerät erfolgt unter Einsatz von auf der Leiterplatte befindlicher (verlöteter) Kontaktstifte oder Stiftleisten. Diese Kontaktstifte/Stiftleisten kontaktieren mit federnden Kontaktstücken, welche im Unterputzgerät eingelötet sind.The controls used to operate flush-mounted devices mostly exist consisting of a rocker and a base, which are locked together. Between these mostly made of plastic parts there is a necessary for actuation Electronics in the form of a circuit board coated on one side with a simple layout. The circuit board can be equipped with electronic and / or electrical components, for example Resistors. Micro switches, elastomer switching mats can be used as switching elements or switch plates ("pop frog") can be used. The contact between The control unit and flush-mounted device are made using those on the circuit board (soldered) contact pins or pin headers. Contact these contact pins / pin headers with resilient contact pieces, which are soldered into the flush-mounted device.

Ein Nachteil eines derartigen, allgemein bekannten Bedienelementes liegt in der hohen erforderlichen Teileanzahl. Die erforderlichen Einzelteile müssen teilweise unter Einsatz teurer Werkzeuge hergestellt werden. Die hohe Teileanzahl erfordert einen erheblichen Aufwand bei der Montage des Bedienelementes. Da die verschiedenen Einzelteile in der Regel übereinander anzuordnen sind, ergibt sich zwangsläufig eine gewisse Mindest-Bauhöhe eines Bedienelementes, die nicht unterschritten werden kann. Hierdurch wird die designerische Freiheit eingeschränkt.A disadvantage of such a generally known control element is the high required number of parts. The required individual parts must be partially used expensive tools are manufactured. The high number of parts requires a considerable amount Effort when installing the control element. Since the various items in are usually to be arranged one above the other, there is inevitably a certain minimum height an operating element that cannot be undercut. Hereby design freedom is restricted.

Der Erfindung liegt die Aufgabe zugrunde, ein Bedienelement eines elektrischen/elektronischen Installationsgerätes der eingangs genannten Art mit vereinfachtem Aufbau anzugeben.The invention has for its object a control element of an electrical / electronic Installation device of the type mentioned with a simplified structure specify.

Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved in connection with the features of the preamble solved by the features specified in the characterizing part of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß das vorgeschlagene Bedienelement aus sehr wenig Einzelteilen zusammengesetzt ist. Dies reduziert die Investitionskosten (beispielsweise die Kosten für Werkzeuge zur Herstellung der Einzelteile) und die Montagekosten. Der Einsatz einer eigenen (getrennten) Leiterplatte und eigener (getrennter) Schaltelemente ist nicht mehr erforderlich. Das vorgeschlagene Bedienelement kann sehr flach ausgebildet werden, was die designerische Freiheit bzw. Gestaltungsmöglichkeit erhöht.The advantages that can be achieved with the invention are, in particular, that the proposed Control element is composed of very few individual parts. This reduces the investment costs (for example, the cost of manufacturing tools of the individual parts) and the assembly costs. The use of your own (separate) circuit board and own (separate) switching elements is no longer required. The proposed Control element can be made very flat, which is the design Freedom or design options increased.

Weitere Vorteile sind aus der nachstehenden Beschreibung ersichtlich.Further advantages are evident from the description below.

In Fig. 1 ist ein Bedienelement erster Ausführungsform im Schnitt dargestellt. Es ist eine Wippe 1 zu erkennen, an deren Innenseite mehrere Rippen 2 angeformt sind. Diese Rippen 2 sind im Eingriff mit auf der Oberseite eines Sockels 4 befindlichen Betätigungsarmen 3. Die Betätigungsarme 3 weisen Kontaktflächen 5 an ihren Enden auf. Hierzu korrespondierende Kontaktflächen 6 sind in entsprechenden Stellen des Sockels 4 integriert. An der Unterseite des Sockels 4 befinden sich mehrere zur Verbindung mit einem Anschlußteil (federnde Kontaktstücke) eines Unterputzgerätes geeignete, integrierte Kontaktstifte 7. Die elektrische Verbindung zwischen diesen Kontaktstiften 7 und den Kontaktflächen 6 erfolgt durch im Sockel 4 integrierte Leiterbahnen 8. An die Leiterbahnen 8 können elektrische/elektronische Bauteile angeschlossen sein (nicht dargestellt).In Fig. 1, an operating element of the first embodiment is shown in section. It is one To recognize rocker 1, on the inside of which a plurality of ribs 2 are formed. This Ribs 2 are engaged with actuating arms located on the top of a base 4 3. The actuating arms 3 have contact surfaces 5 at their ends. Corresponding contact surfaces 6 are in corresponding locations on the base 4 integrated. At the bottom of the base 4 there are several for connection with a connection part (resilient contact pieces) of a flush-mounted device suitable, integrated Contact pins 7. The electrical connection between these contact pins 7 and the contact surfaces 6 are made by conductor tracks 8 integrated in the base 4. To the conductor tracks 8 electrical / electronic components can be connected (not shown).

Die Gestaltung des Sockels 4 beruht auf der Idee, einen Sockel zu schaffen, der neben der üblichen Sockelfunktion möglichst viele Funktionen der bisher üblicherweise eingesetzten zusätzlichen Einzelteile übernimmt, wie

  • die Aufnahme des Layout durch integrierte Leiterbahnen 8 und die Bestückung mit elektrischen/elektronischen Bauelementen (Funktion einer Leiterplatte),
  • die Bestückung mit Schaltelementen bzw. Ausführung der Schaltfunktion - siehe integrierte, sich gegenüberliegende Kontaktflächen 5, 6 und angeformte Betätigungsarme 3 mit Rückstellfunktion zur Rückstellung der Wippe 1 - und
  • die Herstellung der elektrischen Verbindung zwischen Bedienelement und dem Unterputzgerät - siehe angeformte, mit den Leiterbahnen 8 einstückig verbundene Kontaktstifte 7.
The design of the base 4 is based on the idea of creating a base which, in addition to the usual base function, takes on as many functions as possible of the additional items usually used hitherto, such as
  • the inclusion of the layout by integrated conductor tracks 8 and the fitting with electrical / electronic components (function of a printed circuit board),
  • the equipping with switching elements or the execution of the switching function - see integrated, opposing contact surfaces 5, 6 and molded actuating arms 3 with reset function for resetting the rocker 1 - and
  • the establishment of the electrical connection between the control element and the flush-mounted device - see molded contact pins 7 which are integrally connected to the conductor tracks 8.

In Fig. 2 ist eine perspektivische Ansicht der Oberseite eines Sockels 4 dargestellt. Es sind die angeformten Betätigungsarme 3, die mittels der Betätigungsarme beaufschlagbaren integrierten Kontaktflächen 6 und die integrierten Leiterbahnen 8 zu erkennen. 2 shows a perspective view of the top of a base 4. It are the integrally formed actuating arms 3 which can be acted upon by means of the actuating arms integrated contact areas 6 and the integrated conductor tracks 8 to recognize.

In Fig. 3 ist eine Sicht auf die Unterseite eines Sockels 4 dargestellt, wobei insbesondere die Kontaktstifte 7 zu erkennen sind.3 shows a view of the underside of a base 4, in particular the contact pins 7 can be seen.

In Fig. 4 ist ein Bedienelement zweiter Ausführungsform im Schnitt dargestellt. Dieses Bedienelement ist sehr flach ausgebildet und ermöglicht derart die Gestaltung von elektrischen/elektronischen Installationsgeräten mit sehr flachem Design. Der Aufbau des Bedienelementes ist prinzipiell gleichartig dem unter Fig. 1 beschriebenen Aufbau, wobei jedoch aufgrund der flachen Formgebung die zur Beaufschlagung der Betätigungsarme 3 dienenden Rippen 2 lediglich in stark verkleinerter Form vorhanden sind.4 shows an operating element of the second embodiment in section. This Control element is very flat and enables the design of electrical / electronic installation devices with a very flat design. The structure the control element is in principle similar to the structure described in FIG. 1, however, due to the flat shape to act upon the actuating arms 3 serving ribs 2 are only available in a greatly reduced form.

In Fig. 5 sind die einzelnen Schritte zur Herstellung des Sockels 4 dargestellt. Die Herstellung erfolgt vorzugsweise in MID-Technik (Molded Interconnect Devices) und zwar speziell in Zweikomponentenspritzguß-Technik. Dieses spezielle MID-Herstellungsverfahren ermöglicht eine hohe Gestaltungsfreiheit, eine Durchkontaktierung ohne zusätzliche Maßnahmen und eine hohe Flexibilität bezüglich des Schichtaufbaues, wobei die Effizienz des Herstellungsprozesses sehr hoch ist.5 shows the individual steps for producing the base 4. The production is preferably carried out using MID technology (Molded Interconnect Devices) especially in two-component injection molding technology. This special MID manufacturing process enables a high degree of design freedom, through-connection without additional Measures and a high flexibility with regard to the layer structure, whereby the efficiency of the manufacturing process is very high.

In einzelnen wird zur Herstellung des Sockels 4 in einem ersten Schritt eine erste Komponente 9 aus einem galvanisierbarem Kunststoff gespritzt ("erster Schuß"). In einem zweiten Schritt erfolgt die teilweise Umhüllung der Komponente 9 mit einer zweiten Komponente 10 aus einem nicht galvanisierbarem, elektrisch isolierendem Kunststoff ("zweiter Schuß"). Die zweite Komponente 10 dient insbesondere zur Gewährleistung eines mechanisch robusten Aufbaus des Sockels 4 und zu einer elektrischen Isolierung des Sockels zur Wippe 1 und zum Unterputzgerät. In einem dritten Schritt erfolgt eine Oberflächenaktivierung der Komponente 9 aus dem galvanisierbarem Kunststoff. In einem vierten Schritt erfolgt eine Metallisierung der freiliegenden Bereiche der Komponente 9 aus dem galvanisierbarem Kunststoff durch Aufbringung einer ersten Metallschicht 11 (Grundmetallisierung). In einem fünften Schritt erfolgt eine Oberflächenveredelung durch Aufbringung einer zweiten Metallschicht 12 mit sehr guter elektrischer Leitfähigkeit auf die Grundmetallisierung zur Schaffung der Kontaktflächen 5, 6, Kontaktstifte 7 und Leiterbahnen 8. In detail, a first component is used to produce the base 4 in a first step 9 molded from a galvanizable plastic ("first shot"). In one in the second step, component 9 is partially coated with a second Component 10 made of a non-galvanizable, electrically insulating plastic ("second shot"). The second component 10 is used in particular to ensure a mechanically robust structure of the base 4 and for electrical insulation of the base to rocker 1 and the flush-mounted device. In a third step there is a Surface activation of component 9 made of the galvanizable plastic. In one In the fourth step, the exposed areas of the component are metallized 9 made of the galvanizable plastic by applying a first metal layer 11 (basic metallization). In a fifth step, the surface is finished by applying a second metal layer 12 with very good electrical Conductivity on the base metallization to create the contact areas 5, 6, contact pins 7 and conductor tracks 8.

Von Vorteil dabei ist, daß die bei konventionellen Bedienteilen mit einer Leiterplatte zu verlötenden Kontaktstifte/Stiftleisten bei der vorgeschlagenen MID-Lösung von der ersten Komponente 9 gebildet werden, d. h. Leiterbahnen 8 und Kontaktstifte 7 sind ein Teil.The advantage here is that the conventional control panels with a circuit board soldering contact pins / pin headers in the proposed MID solution from the first Component 9 are formed, i. H. Conductor tracks 8 and contact pins 7 are one Part.
