Nach Fig. 1 umfasst die erfindungsgemäße elektrische Anordnung im wesentlichen ein Befehls- und/oder Meldegerät 2 und ein mit diesem lösbar verbundenes Koppelmodul 4. Im dargestellten Ausführungsbeispiel ist ein als Leuchtdrucktaste ausgebildetes Befehls- und Meldegerät dargestellt.According to Fig. 1, the electrical arrangement according to the invention essentially comprises a command and / or signaling device 2 and a releasably connected thereto coupling module 4. In the illustrated embodiment, designed as a light-emitting button command and signaling device is shown.

Dieses besteht im wesentlichen aus einem als beleuchtete Drucktaste ausgebildeten Frontelement 6, drei Funktionselementen 8 und einem das Frontelement 6 und die Funktionselemente 8 verbindenden Befestigungselement 10. Als Funktionselemente 8 sind zum Beispiel ein Öffner-Kontaktelement zur Trennung des Stromkreises, ein Schließer-Kontaktelement zur Fernmeldung eines Ausgelöstsignals und ein Leuchtelement zur Ausgelöstmeldung vor Ort angebracht. Die Kombination von einzelnen Funktionselementen 8 sowie die entsprechende Kombination eines zugehörigen Frontelementes 6 sind je nach gewünschter Funktion frei wählbar.This consists essentially of a trained as an illuminated push button front element 6, three functional elements 8 and the front element 6 and the functional elements 8 connecting fastener 10. As functional elements 8, for example, a normally closed contact element for the separation of the circuit, a make contact element for remote signaling a tripping signal and a Illuminated element for triggering message mounted on site. The combination of individual functional elements 8 and the corresponding combination of an associated front element 6 are freely selectable depending on the desired function.

Die Funktionselemente 8 sind vorzugsweise zumindest was die äußeren Konturen des Gehäuseteils angeht gleich ausgebildet. Sie weisen im wesentlichen flache quaderförmige Gehäuse auf, die auf ihrer oberen schmalen Stirnseite Öffnungen für Betätigungsstößel oder Leuchtelemente, auf ihren seitlichen Schmalseiten einander gegenüberliegende Kabeleinführöffnungen zu den Anschlußstellen insbesondere Schraubklemmen (für die konventionelle Verdrahtung) und auf der unteren Schmalseite Einführöffnungen für Schraubendreher zur Betätigung der Schraubklemmen aufweisen. In der vorliegenden Ausführungsform ist unterhalb jeder Kabeleinführöffnung eine Rastvertiefung 12 zur Befestigung des Koppelmoduls 4 ausgebildet.The functional elements 8 are preferably at least the same as the outer contours of the housing part. They have substantially flat rectangular housing, the openings on their upper narrow side openings for actuating plunger or lighting elements, on their lateral narrow sides opposite Kabeleinführöffnungen to the terminals in particular screw terminals (for conventional wiring) and on the lower narrow side insertion holes for screwdriver for actuating the Have screw terminals. In the present embodiment, a latching recess 12 is formed below each cable insertion opening for attachment of the coupling module 4.

Das Koppelmodul 4 umfasst ein quaderförmiges Gehäuse 40, welches auf seiner Oberseite mechanische Verbindungsmittel 41 (Fig. 2) zur lösbaren Befestigung des Koppelmoduls 4 an dem mindestens einen Funktionselement 8 sowie vorzugsweise elektrische Verbindungsmittel 42 zur elektrischen Kontaktierung zwischen Koppelmodul 4 und dem mindestens einen Funktionselement 8 aufweist. Dabei umfassen die mechanischen Verbindungsmittel 41 auf einer Seite vorzugsweise drei jeweils über einen Freiraum 41 a voneinander beabstandete feststehende Hintergriffe 41 b sowie auf der gegenüberliegenden Seite einen federnd beweglich ausgebildeten Rastarm mit drei jeweils über einen Freiraum 41 a voneinander beabstandeten Rastvorsprüngen 41 c (Fig. 3). Vorzugsweise weist der Rastarm Mittel 41 d zum Angriff eines Werkzeuges auf, mit dessen Hilfe der Rastarm zur Entriegelung einer Rastverbindung verbiegbar ist. Bevorzugt sind diese Mittel 41 d als schlitzförmige Aufnahme zum Eingriff eines Schraubendrehers ausgeführt. Denkbar sind allerdings auch andere Mittel 41 d wie Fortsätze zur Handbetätigung. Die Rastvorsprünge 41 c und die Hintergriffe 41 b sind kopfseitig mit zur Oberfläche des Koppelmoduls 4 hin abfallenden Schrägflächen ausgebildet, so dass durch ein einfaches Aufeinanderdrücken von Befehls- und/oder Meldegerät 2 und Koppelmodul 4 diese durch eine mechanische Rastverbindung miteinander verbindbar sind.The coupling module 4 comprises a cuboidal housing 40 which has on its upper side mechanical connecting means 41 (FIG. 2) for releasably securing the coupling module 4 to the at least one functional element 8 and preferably electrical connecting means 42 for electrical contacting between the coupling module 4 and the at least one functional element 8 having. In this case, the mechanical connecting means 41 preferably comprise on one side three spaced from each other via a free space 41 a fixed rearward handles 41 b and on the opposite side a resiliently movable latching arm with three each spaced over a free space 41 a latching projections 41 c (Fig ). Preferably, the latching arm has means 41 d for attacking a tool, by means of which the latching arm for unlocking a latching connection is bendable. Preferably, these means 41 d are designed as a slot-shaped receptacle for engagement of a screwdriver. Conceivable, however, are other means 41 d as extensions for manual operation. The locking projections 41 c and the rear handles 41 b are formed on the head side sloping to the surface of the coupling module 4 sloping surfaces, so that they are connected to each other by a simple pressing together of command and / or signaling device 2 and coupling module 4 by a mechanical latching connection.

Die elektrischen Verbindungsmittel 42 sind mit Vorteil durch Kontaktfedern gebildet, die im Gehäuseinneren die elektrische Verbindung zu einer Logikeinheit darstellen. Vorzugsweise sind die Kontaktfedern kraftformschlüssig und lösbar im Gehäuse fixierbar, so dass zum einen eine sichere Kontaktierung und zum anderen durch Hinzufügen oder Herausnehmen der Kontaktfedern eine einfache Erweiterung oder Verminderung von Kontaktstellen ermöglicht wird. In einer bevorzugten Ausführung hat das Koppelmodul 4 die Breite von drei Funktionselementen 8 und weist insgesamt sechs Öffnungen zur Aufnahme bzw. Durchführung der Kontaktfedern auf. Dabei sind die Öffnungen derart positioniert, dass die Kontaktfedern bei Befestigung des Koppelmoduls 4 an den Funktionselementen 8 des Befehls- und Meldegerätes direkt in die Schraubendreher-Einführöffnungen der Funktionsmodule hineinragen und dort auf die Schraubköpfe der Anschlußklemmen der Funktionselemente 8 drücken und so eine elektrisch leitende Verbindung zwischen Koppelmodul 4 und den Funktionselementen 8 gewährleisten. Zur mechanischen Befestigung des Koppelmoduls 4 wird dieses entweder von unten i.w. parallel auf die Unterseite der Funktionselemente 8 aufgedrückt oder mit seinen feststehenden Hintergriffen 41 b in die Rastvertiefung 12 auf einer Seite der Funktionselemente 8 eingehakt und Richtung Funktionselemente 8 eingeschwenkt bis der gegenüberliegende Rastarm des Koppelmoduls 4 mit seinen Rastvorsprüngen 41 c in die gegenüberliegenden Rastvertiefungen 12 der Funktionselemente 8 einrastet. Hierdurch wird im wesentlichen zeitgleich eine mechanische und elektrische Verbindung hergestellt. Das Koppelmodul 4 weist auf seiner den Funktionselementen 8 zugekehrten Seite hervorstehende, in Positionierungsöffnungen 44 der Unterseite der Funktionselemente 8 eingreifende Fangmittel 45 zur Sicherung gegen seitliche Verschiebung auf. Hierdurch wird die Position der modular aufgebauten Anordnung gegen ungewolltes Verschieben - wodurch auch Fehlfunktionen hervorgerufen werden können - zusätzlich gesichert. Mit Vorteil sind die Positionierungsöffnungen 44 als eckige Erweiterungen der Schraubendreheröffnungen ausgebildet (Fig. 3 und Fig. 4).
Die Rastvertiefungen 12 jedes Funktionselementes 8 weisen vorzugsweise seitliche Begrenzungswände 8a auf, die ebenfalls zum Zwecke der Sicherung gegen seitliche Verschiebung und/oder Verdrehung zwischen Koppelelement 4 und Befehls- und Meldegerät 2 mit den Hintergriffen 41 b bzw. den Rastvorsprüngen 41 c zusammenwirken (Fig. 4).
The electrical connection means 42 are advantageously formed by contact springs, which constitute the electrical connection to a logic unit inside the housing. Preferably, the contact springs are frictionally and releasably fixable in the housing, so that on the one hand a secure contact and on the other by adding or removing the contact springs a simple extension or reduction of contact points is possible. In a preferred embodiment, the coupling module 4 has the width of three functional elements 8 and has a total of six openings for receiving or performing the contact springs. The openings are positioned such that the contact springs protrude when attaching the coupling module 4 to the functional elements 8 of the command and signaling device directly into the screwdriver insertion of the function modules and press there on the screw heads of the terminals of the functional elements 8 and so an electrically conductive connection ensure between coupling module 4 and the functional elements 8. For mechanical attachment of the coupling module 4, this is either from below iw pressed parallel to the underside of the functional elements 8 or hooked with its fixed rear handles 41 b in the locking recess 12 on one side of the functional elements 8 and direction functional elements 8 pivoted to the opposite locking arm of the coupling module. 4 with its latching projections 41 c in the opposite locking recesses 12 of the functional elements 8 engages. As a result, a mechanical and electrical connection is made substantially at the same time substantially. The coupling module 4 has on its side facing the functional elements 8 side protruding, in positioning openings 44 of the underside of the functional elements 8 engaging catching means 45 for securing against lateral displacement. As a result, the position of the modular structure against unintentional shifting - which can also cause malfunctions - additionally secured. The positioning openings 44 are advantageously designed as angular extensions of the screwdriver openings (FIGS. 3 and 4).
The locking recesses 12 of each functional element 8 preferably have lateral boundary walls 8a, which also cooperate for the purpose of securing against lateral displacement and / or rotation between the coupling element 4 and command and signaling device 2 with the rear handles 41b and the latching projections 41c (Fig. 4).

Um die Berührungssicherheit der elektrischen Anordnung hinsichtlich der seitlichen Kabeleinführöffnungen der Funktionselemente 8 zu gewährleisten können die Hintergriffe 41 b und die Rastvorsprünge 41 c des Rastarms derart ausgebildet sein, dass die Kabeleinführöffnungen bei montierter Koppeleinheit 4 verschlossen sind. Hierfür können die Hintergriffe 41 b bzw. die Rastvorsprünge 41 c mit schildartigen Fortsätzen ausgebildet sein. In einer anderen Ausführung können die Hintergriffe 41 b und die Rastvorsprünge 41 c zwecks Befestigung des Koppelmoduls 4 auch unmittelbar in die Kabeleinführöffnungen der Funktionselemente 8 eingreifen und so eine Berührungssicherheit gewährleisten.In order to ensure the contact reliability of the electrical arrangement with respect to the lateral cable entry openings of the functional elements 8, the rear handles 41 b and the latching projections 41 c of the latching arm may be designed such that the cable entry openings are closed when the coupling unit 4 is mounted. For this purpose, the rear grips 41 b and the latching projections 41 c may be formed with shield-like extensions. In another embodiment, the rear handles 41 b and the latching projections 41 c for the purpose of attaching the coupling module 4 also engage directly in the cable entry openings of the functional elements 8 and thus ensure a contact security.

Die Fig. 2 zeigt die erfindungsgemäße Anordnung gemäß Fig. 1, wobei ein seitlich befestigtes Funktionselement 8 kein Deckelteil aufweist. Hier ist deutlich erkennbar, dass bei montierter Koppeleinheit 4 die feststehenden Hintergriffe 41 b und die gegenüber angeordneten Rastvorsprünge 41 c des Rastarms in die unterhalb der Kabeleinführöffnungen der Funktionselemente 8 befindlichen Rastvertiefungen 12 einer jeden Seite der Funktionselemente 8 eingreifen. Auch ist die Kontaktierung zwischen Koppelmodul 4 und den Funktionselementen 8 durch die auf die Schraubköpfe der Anschlußklemmen der Funktionselemente 8 drückenden Kontaktfedern erkennbar.FIG. 2 shows the arrangement according to the invention according to FIG. 1, wherein a laterally fixed functional element 8 has no cover part. Here it is clearly seen that when mounted coupling unit 4, the fixed rear grips 41 b and the opposite locking projections 41 c of the latching arm engage in the below the cable entry openings of the functional elements 8 locking recesses 12 of each side of the functional elements 8. Also, the contact between the coupling module 4 and the functional elements 8 can be seen by the pressing on the screw heads of the terminals of the functional elements 8 contact springs.

In Fig. 1 und 2 sind weiterhin die Busanschlußmittel 43 in Form einer Anschlußbuchse zur Aufnahme eines Steckerteils dargestellt.In Fig. 1 and 2, the bus connection means 43 are further shown in the form of a connector socket for receiving a plug part.

Mit Vorteil soll die Anbindung an ein serielles Bussystem, insbesondere AS-i oder Profibus realisiert werden. Hierfür sind natürlich auch entsprechende andere Busanschlußmittel vorgesehen, wie Messerkontaktanschlüsse an eine AS-i-Zweidrahtleitung oder einfache Schraubanschlüsse oder dergleichen mehr.Advantageously, the connection to a serial bus system, in particular AS-i or Profibus should be realized. Of course, corresponding other bus connection means are provided for this purpose, such as blade contact connections to an AS-i two-wire line or simple screw connections or the like.

In Fig. 3 ist noch einmal das Koppelmodul 4 separat dargestellt.In Fig. 3, the coupling module 4 is shown separately again.
