Description

Die vorliegende Erfindung betrifft einen Anschlussblock für elektrische Leitungen nach dem Oberbegriff des Anspruchs 1, um beispielsweise Leuchten oder andere elektrische Geräte an eine elektrische Leitung anzuschließen. Ein solcher anschlussblock ist aus der EP 2 631 996 A2 bekannt. Die EP 1 388 914 A1 offenbart einen ähnlichen Anschlussblock. EP2 631 996 A2 offenbart den Oberbegriff des Anspruchs 1.The present invention relates to a connection block for electrical lines according to the preamble of claim 1, for example to connect lights or other electrical devices to an electrical line. Such a connection block is from EP 2 631 996 A2 known. the EP 1 388 914 A1 discloses a similar terminal block. EP2 631 996 A2 discloses the preamble of claim 1.

Insbesondere bei Deckenleuchten, jedoch auch bei Wandleuchten oder anderen elektrischen Geräten, die an Decke oder Wand montiert werden müssen, ergibt sich häufig die Situation, dass der Monteur über Kopf montieren muss, wobei lediglich zwei Hände zur Verfügung stehen. Bei Verwendung von hierzu üblichen Lüsterklemmen müssen Kabel, Werkzeug und Lüsterklemme gleichzeitig gehalten werden, was sowohl bei einer Erstmontage wie auch bei einer Reparatur oder einem Austausch der Installation zu Schwierigkeiten führen kann.Particularly in the case of ceiling lights, but also in the case of wall lights or other electrical devices that have to be mounted on the ceiling or wall, the situation often arises that the installer has to mount overhead, with only two hands being available. When using the usual luster terminals for this purpose, the cable, tool and luster terminal must be held at the same time, which can lead to difficulties both during initial assembly and when repairing or replacing the installation.

Es ist die Aufgabe der vorliegenden Erfindung, einen Anschlussblock für elektrische Leitungen zu schaffen, mit dem sowohl eine einfache Montage wie auch eine einfache Demontage möglich ist.It is the object of the present invention to provide a connection block for electrical lines with which both simple assembly and simple disassembly are possible.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.This problem is solved by the features of claim 1.

Durch Vorsehen von Klemmkontakten in dem Anschlussblock, die durch eine Betätigungswippe in ihre Öffnungsstellung bringbar sind, können elektrische Leitungen auf äußerst einfache Weise wieder aus dem Anschlussblock entfernt werden, wenn eine Reparatur oder Demontage erforderlich ist. Hierzu muss lediglich die Betätigungswippe mit einem Finger niedergedrückt werden, so dass sich der Klemmkontakt öffnet. Gleichzeitig weist der Anschlussblock eine Koppeleinrichtung auf, so dass eine Steckaufnahme für einen elektrischen Stecker mit dem Anschlussblock gekoppelt werden kann. Hierdurch kann bei angekoppeltem Anschlussblock ein elektrisches Gerät auf einfachste Weise mit dem Anschlussblock verbunden werden, indem der elektrische Stecker in die Steckaufnahme eingesteckt wird.By providing terminal contacts in the connection block, which can be brought into their open position by means of an actuating rocker, electrical lines can be removed from the connection block again in an extremely simple manner if repair or disassembly is required. For this purpose, only the rocker switch must be depressed with a finger, so that the Clamp contact opens. At the same time, the connection block has a coupling device, so that a plug-in receptacle for an electrical plug can be coupled to the connection block. As a result, when the connection block is coupled, an electrical device can be connected to the connection block in the simplest manner by the electrical plug being plugged into the plug-in receptacle.

Die Steckaufnahme ist quaderförmig, wobei die Betätigungswippen zumindest teilweise seitlich von der Steckaufnahme vorstehen. Hierdurch wird eine besonders gute Betätigung der Betätigungswippen erzielt, da die Steckaufnahme eine Führungswand für den Betätigungsfinger des Monteurs bildet.The plug-in receptacle is cuboid, with the rocker switches protruding at least partially laterally from the plug-in receptacle. This achieves a particularly good actuation of the rocker switches, since the plug-in receptacle forms a guide wall for the fitter's actuating finger.

Vorteilhafte Ausführungsformen der Erfindung sind in der Beschreibung, der Zeichnung sowie den Unteransprüchen beschrieben.Advantageous embodiments of the invention are described in the description, the drawing and the dependent claims.

Nach einer ersten vorteilhaften Ausführungsform können die Betätigungswippen einstückig miteinander verbunden sein. Dies ermöglicht eine kostengünstige Herstellung und eine sehr schnelle Montage, da sämtliche Betätigungswippen zu einem Bauteil integriert sind.According to a first advantageous embodiment, the rocker switches can be connected to one another in one piece. This enables cost-effective production and very quick assembly, since all the rocker switches are integrated into one component.

Nach einer weiteren vorteilhaften Ausführungsform können die Betätigungswippen Teil einer Gehäuseabdeckung sein, was die Montage ebenfalls signifikant erleichtert, da keine einzelnen Wippen an der richtigen Position montiert werden müssen. Vielmehr muss lediglich die Gehäuseabdeckung mit dem Gehäuse verbunden werden, was insbesondere durch Aufklipsen auf das Gehäuse ermöglicht werden kann. In diesem Fall ist es lediglich erforderlich, die Klemmkontakte in das Gehäuse einzusetzen und die Gehäuseabdeckung auf das Gehäuse aufzuklipsen, um den werkzeuglos kontaktierbaren Anschlussblock fertigzustellen.According to a further advantageous embodiment, the rocker switches can be part of a housing cover, which also makes assembly significantly easier, since individual rockers do not have to be mounted in the correct position. Rather, only the housing cover has to be connected to the housing, which can be made possible in particular by clipping it onto the housing. In this case, it is only necessary to insert the terminal contacts into the housing and clip the housing cover onto the housing in order to complete the terminal block that can be contacted without tools.

Nach einer weiteren vorteilhaften Ausführungsform kann die Gehäuseabdeckung über ein Filmscharnier mit dem Gehäuse verbunden sein. Dies ermöglicht eine einstückige Ausbildung von Gehäuse und Gehäuseabdeckung, wobei nach einem Umklappen der Gehäuseabdeckung auf das Gehäuse eine Rasteinrichtung dafür sorgen kann, dass die Gehäuseabdeckung geschlossen bleibt.According to a further advantageous embodiment, the housing cover can be connected to the housing via a film hinge. This enables the housing and housing cover to be formed in one piece, with a latching device being able to ensure that the housing cover remains closed after the housing cover has been folded over onto the housing.

Nach einer weiteren vorteilhaften Ausführungsform kann jede Betätigungswippe ein Filmscharnier aufweisen, wodurch eine freie und unabhängige Bewegung der einzelnen Betätigungswippen sichergestellt ist.According to a further advantageous embodiment, each rocker switch can have a film hinge, which ensures free and independent movement of the individual rocker switches.

Nach einer weiteren vorteilhaften Ausführungsform kann die Koppeleinrichtung zum Koppeln der Steckaufnahme eine Gleitführung mit einem Anschlag und einer Verriegelung aufweisen. Bei dieser Ausführungsform sind Anschlussblock und Steckaufnahme ineinander einschiebbar. Die Gleitführung sorgt für eine sichere und dauerhafte Verbindung und durch Anschlag und Verriegelung, beispielsweise Reibschlussverriegelung, ist gewährleistet, dass beide Bauteile relativ zueinander richtig und dauerhaft positioniert sind.According to a further advantageous embodiment, the coupling device for coupling the plug receptacle can have a sliding guide with a stop and a lock. In this embodiment, the connection block and plug-in receptacle can be pushed into one another. The sliding guide ensures a secure and permanent connection and the stop and locking, for example frictional locking, ensures that both components are correctly and permanently positioned relative to one another.

Nach einer weiteren vorteilhaften Ausführungsform der Erfindung kann im Bereich jedes Klemmkontakts eine Kontaktierungsöffnung vorgesehen sein, durch die ein elektrischer Leiter eines Steckers in den Klemmkontakt einführbar ist, um eine elektrische Verbindung mit einer von dem Klemmkontakt kontaktierten Leitung herzustellen. Hierbei können vorzugsweise eine sich in Steckrichtung des Steckers durch die Kontaktierungsöffnung erstreckende Achse und eine Achse entlang der die Leitung in das Gehäuse des Anschlussblocks einführbar ist, quer zueinander verlaufen. Dies bedeutet, dass die Steckrichtung des in die Steckaufnahme einzuführenden elektrischen Steckers und die Zuführrichtung der elektrischen Leitungen quer zueinander orientiert sind, insbesondere etwa annähernd rechtwinklig oder unter einem stumpfen Winkel. Eine solche Anordnung hat sich in der Praxis bei der Montage als vorteilhaft erwiesen.According to a further advantageous embodiment of the invention, a contacting opening can be provided in the area of each clamping contact, through which an electrical conductor of a plug can be inserted into the clamping contact in order to establish an electrical connection with a line contacted by the clamping contact. In this case, an axis extending through the contacting opening in the plug-in direction of the plug and an axis along which the line can be inserted into the housing of the connection block can preferably run transversely to one another. This means that the insertion direction of the electrical plug to be inserted into the receptacle and the feed direction of the electrical lines are oriented transversely to one another, in particular approximately at right angles or at an obtuse angle. Such an arrangement has proven to be advantageous in practice during assembly.

Nach einer weiteren vorteilhaften Ausführungsform können die elektrischen Leitungen entlang einer Achse in das Gehäuse einführbar sein, die unter einem spitzen Winkel zur Ebene der Gehäuseabdeckung verläuft, wobei der spitze Winkel insbesondere zwischen 5° und 45° beträgt. Auch dies trägt zu einer vereinfachten Montage und Demontage bei, wenn die elektrischen Leitungen in den Anschlussblock eingeführt oder aus diesem entfernt werden müssen.According to a further advantageous embodiment, the electrical lines can be inserted into the housing along an axis which runs at an acute angle to the plane of the housing cover, the acute angle being in particular between 5° and 45°. This also contributes to simplified assembly and disassembly when the electrical lines have to be inserted into or removed from the connection block.

Erfindungsgemäß ist mit dem Anschlussblock eine Steckaufnahme für einen elektrischen Steckverbinder gekoppelt, dessen Einsteckrichtung sich insbesondere quer zur Einführrichtung der elektrischen Leiter erstreckt. Insbesondere können Einsteckrichtung und Einführrichtung unter einem Winkel von etwa 90° bis 135°, insbesondere etwa 95° bis 125° zueinander verlaufen.According to the invention, a plug-in receptacle for an electrical connector is coupled to the terminal block, the insertion direction of which extends in particular transversely to the direction of insertion of the electrical conductors. In particular, the plug-in direction and the insertion direction can run at an angle of approximately 90° to 135°, in particular approximately 95° to 125°, to one another.

Nach einer weiteren vorteilhaften Ausführungsform kann die Steckaufnahme oberhalb der Kontaktierungsöffnungen angeordnet sein, wodurch auf zusätzliche Leiter innerhalb des Anschlussblocks verzichtet werden kann, da die Kontakte des Steckers dann durch die Kontaktierungsöffnungen unmittelbar in Federklemmen der Klemmkontakte eingeführt werden können.According to a further advantageous embodiment, the plug receptacle can be arranged above the contacting openings, which means that additional conductors within the connection block can be dispensed with, since the contacts of the plug can then be inserted directly into the spring terminals of the terminal contacts through the contacting openings.

Nach einer weiteren vorteilhaften Ausführungsform kann der Anschlussblock in eine Anschlussdose eingesetzt sein, die einen Klappdeckel aufweist, der in seiner geschlossenen Stellung verrastet. Hierdurch lassen sich die elektrischen Leitungen und auch der Anschlussbereich des Anschlussblocks schützen, insbesondere wenn der Klappdeckel die Betätigungswippen überdeckt.According to a further advantageous embodiment, the connection block can be inserted into a connection box which has a hinged cover which latches in its closed position. In this way, the electrical lines and also the connection area of the connection block can be protected, in particular if the hinged cover covers the rocker switches.

Fig. 1 zeigt eine perspektivische Ansicht eines werkzeuglos kontaktierbaren Anschlussblocks 10 für elektrische Leitungen sowie einer mit dem Anschlussblock 10 koppelbaren Steckaufnahme 12, in die ein elektrischer Stecker einsteckbar ist, um ein elektrisches Gerät, beispielsweise eine Deckenleuchte mit elektrischen Leitungen zu verbinden, die in den Anschlussblock 10 eingeführt sind. 1 shows a perspective view of a connection block 10 for electrical lines that can be contacted without tools and a plug-in receptacle 12 that can be coupled to the connection block 10 and into which an electrical plug can be inserted in order to connect an electrical device, for example a ceiling light, to electrical lines that are inserted into the connection block 10 are.

Wie Fig. 2 verdeutlicht, besteht der Anschlussblock 10 aus insgesamt nur drei verschiedenen Komponenten, nämlich einem Gehäuse 14, in das Gehäuse eingesetzten Klemmkontakten 16 sowie einer Gehäuseabdeckung 18.As 2 makes clear, the connection block 10 consists of a total of only three different components, namely a housing 14, terminal contacts 16 inserted into the housing and a housing cover 18.

Das Gehäuse 14 besitzt grundsätzlich die Form eines flachen Quaders und in dem Gehäuse sind bei dem dargestellten Ausführungsbeispiel insgesamt drei Kammern für jeweils einen Klemmkontakt 16 gebildet. Jede Kammer besitzt an ihrer Vorderseite zwei kreisförmige Einlassöffnungen 20, durch die jeweils eine elektrische Leitung (nicht dargestellt) entlang einer Achse A1 oder A2 in das Gehäuse 14 eingeführt werden kann. Die Achsen A1 oder A2 bezeichnen somit die Einführrichtung der elektrischen Leiter.The housing 14 basically has the shape of a flat cuboid and in the illustrated embodiment a total of three chambers for one clamping contact 16 each are formed in the housing. Each chamber has two circular inlet openings 20 at its front, through each of which an electrical lead (not shown) can be introduced into the housing 14 along an axis A1 or A2. The axes A1 or A2 thus denote the direction of insertion of the electrical conductors.

In jede Kammer des Gehäuses 14 ist ein Klemmkontakt 16 eingesetzt (vgl. Fig. 3), so dass beim Einführen eines Leiters in eine Einführöffnung 20 dieser selbsttätig in dem zugehörigen Klemmkontakt 16 verklemmt und gehalten ist. Bei dem dargestellten Ausführungsbeispiel können somit je Klemmkontakt 16 insgesamt zwei elektrische Leitungen kontaktiert werden.A clamping contact 16 is inserted into each chamber of the housing 14 (cf. 3 ), so that when a conductor is inserted into an insertion opening 20, it is automatically clamped and held in the associated clamping contact 16. In the exemplary embodiment shown, a total of two electrical lines can thus be contacted for each terminal contact 16 .

Fig. 3 zeigt das Gehäuse 14 mit in die Kammern eingesetzten Klemmkontakten 16, wobei jedoch die Gehäuseabdeckung 18 noch nicht aufgesetzt ist. Durch Aufsetzen der Gehäuseabdeckung 18 auf das Gehäuse 16 gleiten zwei an der Gehäuseabdeckung 18 vorgesehene Rastlaschen 24 über an dem Gehäuse 14 angeformte Rastnasen 26, so dass die Gehäuseabdeckung 18 an dem Gehäuse 14 aufgeklipst und verrastet ist (vgl. Fig. 1). 3 shows the housing 14 with the terminal contacts 16 inserted into the chambers, but with the housing cover 18 not yet in place. By placing the housing cover 18 on the housing 16, two locking tabs 24 provided on the housing cover 18 slide over locking lugs 26 formed on the housing 14, so that the housing cover 18 is clipped and locked on the housing 14 (cf. 1 ).

Die Klemmkontakte 16 sind so ausgebildet, dass diese durch Niederdrücken in eine Öffnungsstellung gebracht werden können, in welcher eine elektrische Leitung wieder aus dem Klemmkontakt entfernbar ist. Bei dem Anschlussblock 10 erfolgt das Niederdrücken eines Klemmkontakts durch eine zugeordnete Betätigungswippe 28, wobei jedem Klemmkontakt 16 eine Betätigungswippe 28 zugeordnet ist. Alle drei Betätigungswippen 28 sind bei dem dargestellten Ausführungsbeispiel einstückig miteinander verbunden und Teil der Gehäuseabdeckung 18. Um eine freie Bewegbarkeit der einzelnen Betätigungswippen 28 unabhängig voneinander zu gewährleisten, ist jede Betätigungswippe 28 über ein Filmscharnier 30 mit der Gehäuseabdeckung 18 verbunden. Auch ist es möglich, die Gehäuseabdeckung 18 selbst über ein (nicht dargestelltes) Filmscharnier mit dem Gehäuse 14 zu verbinden, so dass die Gehäuseabdeckung 18 nach Einsetzen der Klemmkontakte 16 in die Kammern lediglich umgeklappt und verrastet werden muss. Ein solches Filmscharnier könnte beispielsweise entlang der hinteren Kante 32 des Gehäuses 14 angeformt werden.The terminal contacts 16 are designed in such a way that they can be brought into an open position by pressing them down, in which an electrical line can be removed from the terminal contact again. In connection block 10 , a clamp contact is pressed down by an associated rocker switch 28 , with each clamp contact 16 being associated with a rocker switch 28 is. In the exemplary embodiment shown, all three rocker switches 28 are connected to one another in one piece and are part of the housing cover 18. In order to ensure that the individual rocker switches 28 can move freely independently of one another, each rocker switch 28 is connected to the housing cover 18 via a film hinge 30. It is also possible to connect the housing cover 18 itself to the housing 14 via a film hinge (not shown), so that the housing cover 18 only has to be folded over and latched after the terminal contacts 16 have been inserted into the chambers. Such a film hinge could be formed along the rear edge 32 of the housing 14, for example.

Wie insbesondere die Fig. 2 und Fig. 3 verdeutlichen, ist an der Unterseite jeder Betätigungswippe 28 ein Zapfen 34 angeformt, der bei Druck auf die Betätigungswippe 28 eine Kraft auf den Klemmkontakt 16 ausübt, so dass sich dieser in die Öffnungsstellung bewegt.Like those in particular 2 and 3 illustrate, a pin 34 is formed on the underside of each rocker switch 28, which exerts a force on the terminal contact 16 when pressure is applied to the rocker switch 28, so that it moves into the open position.

Zum Koppeln des Anschlussblocks 10 mit der Steckaufnahme 12 ist zu beiden Seiten des Anschlussblocks 10 eine Gleitrippe 40 angeformt, an deren vorderem Ende sich ein Anschlag 42 befindet. Entsprechend weist die Steckaufnahme 12 an ihrer Unterseite zwei parallele Gleitnuten 44 auf, in welche die Gleitrippen 40 eingeschoben werden können, bis die Steckaufnahme 12 an den Anschlägen 42 anstößt. In dieser Position können die beiden Bauteile durch einen Rasthaken 46 an der Steckaufnahme und/oder durch ein Reibschlusselement 48 an den Gleitrippen aneinander fixiert werden.In order to couple the connection block 10 to the plug-in socket 12, a sliding rib 40 is formed on both sides of the connection block 10, and a stop 42 is located at the front end of said rib. Correspondingly, the plug-in receptacle 12 has two parallel sliding grooves 44 on its underside, into which the sliding ribs 40 can be pushed until the plug-in receptacle 12 abuts against the stops 42 . In this position, the two components can be fixed to one another by a latching hook 46 on the socket and/or by a frictional engagement element 48 on the sliding ribs.

Im gekoppelten Zustand von Anschlussblock 10 und Steckaufnahme 12 (vgl. Fig. 4) kann ein elektrischer Stecker in einer Steckrichtung S in die Steckaufnahme 12 eingesteckt werden. Damit elektrische Kontakte des Steckers mit den Klemmkontakten 16 in Verbindung treten können, sind im Bereich jedes Klemmkontakts 16 an der Gehäuseabdeckung 18 drei Kontaktierungsöffnungen 50 vorgesehen, durch die ein elektrischer Leiter des Steckers in den zugehörigen Klemmkontakt 16 einführbar ist, um eine elektrische Verbindung mit einer von den Klemmkontakten 16 kontaktierten Leitung herzustellen. Wie insbesondere Fig. 4 verdeutlicht, verlaufen dabei eine sich in Steckrichtung S durch die Kontaktierungsöffnung 50 erstreckende Achse und eine Achse A1 bzw. A2, entlang der die elektrische Leitung in das Gehäuse 14 einführbar ist, quer zueinander. Für diese Kontaktierung durch einen elektrischen Leiter des Steckers weist jeder Klemmkontakt 16 eine an seiner Rückseite angeformte und nach oben offene Federklemme 52 auf, in die der elektrische Leiter leitend eingesteckt werden kann, nachdem dieser durch die Kontaktierungsöffnung 50 hindurchgetreten ist.When the connection block 10 and plug-in receptacle 12 are connected (cf. 4 ) an electrical plug can be plugged into the plug-in receptacle 12 in a plug-in direction S. So that electrical contacts of the plug can be connected to the terminal contacts 16, three contact openings 50 are provided in the area of each terminal contact 16 on the housing cover 18, through which an electrical conductor of the plug can be inserted into the associated terminal contact 16 in order to establish an electrical connection with a line contacted by the terminal contacts 16 . How in particular 4 clarified, an axis extending through the contact opening 50 in the insertion direction S and an axis A1 or A2, along which the electrical line can be inserted into the housing 14, run transversely to one another. For this contacting by an electrical conductor of the plug, each clamping contact 16 has a spring clamp 52 formed on its rear side and open at the top, into which the electrical conductor can be conductively inserted after it has passed through the contacting opening 50 .

Wie eine Zusammenschau von Fig. 1 und Fig. 4 verdeutlicht, sind die elektrischen Leitungen entlang einer Achse A1 oder A2 in das Gehäuse 14 einführbar, die unter einem spitzen Winkel zur Ebene der Gehäuseabdeckung 14 verläuft, wobei der Winkel insbesondere zwischen etwa 5° und 45° betragen kann. Weiterhin verlaufen die Einsteckrichtung S (Fig. 4) und die Einführrichtung A1 oder A2 der elektrischen Leitungen unter einem Winkel von etwa 90° bis 135°, insbesondere unter etwa 95° bis 125° zueinander. Weiterhin verdeutlicht eine Zusammenschau von Fig. 1 und Fig. 4, dass der Anschlussblock 10 und die Steckaufnahme 12 ineinander einschiebbar sind und dass die Steckaufnahme 12 im eingeschobenen und miteinander gekoppelten Zustand oberhalb der Kontaktierungsöffnungen 50 angeordnet ist. Im gekoppelten Zustand stehen die Betätigungswippen 28 zumindest teilweise seitlich von der Steckaufnahme 12 vor, wodurch eine vordere Wand 13 (Fig. 5) der Steckaufnahme 12 eine Anschlagwand bzw. Führungswand für einen Betätigungsfinger des Monteurs bildet.Like a synopsis of 1 and 4 As illustrated, the electrical lines can be inserted into the housing 14 along an axis A1 or A2, which runs at an acute angle to the plane of the housing cover 14, the angle being in particular between approximately 5° and 45°. Furthermore, the insertion direction S ( 4 ) and the insertion direction A1 or A2 of the electrical lines at an angle of approximately 90° to 135°, in particular approximately 95° to 125° to one another. Furthermore, a synopsis of 1 and 4 that the terminal block 10 and the plug-in receptacle 12 can be pushed into one another and that the plug-in receptacle 12 is arranged above the contacting openings 50 when it is pushed in and coupled to one another. In the coupled state, the actuating rockers 28 protrude at least partially laterally from the plug-in receptacle 12, as a result of which a front wall 13 ( figure 5 ) of the plug-in receptacle 12 forms a stop wall or guide wall for an actuating finger of the fitter.

Der vorstehend beschriebene Anschlussblock 10 mit gekoppelter Steckaufnahme 12 kann in eine Anschlussbasis 60 eingesetzt werden, wie dies in Fig. 6 gezeigt ist. Elektrische Leiter 62 eines Kabels, welche durch die Rückwand der Anschlussbasis 60 eingeführt sind, können dann durch einfaches Einstecken in den Anschlussblock 10 mit den Klemmkontakten 16 verbunden werden. Nach der Kontaktierung der elektrischen Leitungen 62 können diese sowie die Betätigungswippen 28 durch einen Klappdeckel 64 geschützt werden, der im geschlossenen Zustand an einem Steg 66 der Anschlussbasis 60 schwenkbar befestigt ist und in der geschlossenen Stellung über einen Rasthaken 68 verrastet, der an dem Klappdeckel 64 angeformt und mit Hilfe eines Schraubendrehers auch wieder lösbar ist. Der Außenumfang der Anschlussbasis kann durch einen zweiten Deckel geschlossen werden, an dem auch eine Abdeckung für den in Fig. 7 noch offenen Teil der Anschlussbasis 60 angeformt ist. Durch einen offenen Randabschnitt des zweiten Deckels lässt sich dann ein elektrischer Stecker in die Steckaufnahme 12 einstecken.The above-described terminal block 10 with coupled receptacle 12 can be inserted into a terminal base 60 as shown in FIG 6 is shown. Electrical conductors 62 of a cable, which are introduced through the rear wall of the connection base 60, can then be simply plugged into the Connection block 10 are connected to the terminal contacts 16. After contact has been made with the electrical lines 62, these and the rocker switches 28 can be protected by a hinged cover 64 which, when closed, is pivotably attached to a web 66 of the connection base 60 and, in the closed position, latches via a latching hook 68 which is attached to the hinged cover 64 molded on and can also be detached again with the help of a screwdriver. The outer perimeter of the connection base can be closed by a second lid, which also has a cover for the in 7 still open part of the connection base 60 is formed. An electrical plug can then be plugged into the socket 12 through an open edge section of the second cover.

Wie Fig. 6 und 7 zeigen, ist der Klappdeckel 64 etwa viertelkreisförmig ausgebildet und an einem etwa radial verlaufenden Rand klappbar befestigt.As Figures 6 and 7 show, the hinged cover 64 is formed approximately in the shape of a quarter circle and is foldably fastened to an approximately radially extending edge.

Fig. 8 und 9 zeigen eine weitere Ausführungsform einer Anschlussbasis, die als Deckenanschluss 70 ausgebildet ist. Der Deckenanschluss 70 ist wie auch die Anschlussbasis 60 mit einem kreisförmigen Umfang ausgebildet und ein mit der Steckaufnahme 12 gekoppelter Anschlussblock 10 ist so an dem Deckenanschluss 70 befestigt, dass die Einstecköffnung der Steckführung 12 bündig zu der Außenseite des Deckenanschlusses 70 verläuft. Figures 8 and 9 show another embodiment of a connection base, which is designed as a ceiling connection 70. Like the terminal base 60 , the ceiling connector 70 is formed with a circular periphery, and a terminal block 10 coupled to the socket 12 is attached to the ceiling connector 70 such that the insertion opening of the connector guide 12 is flush with the outside of the ceiling connector 70 .

Der Deckenanschluss 70 kann auf einfache Weise in eine (nicht dargestellte) Anschlussdose eingesetzt werden, die an der Decke befestigt ist. Zuvor müssen lediglich die elektrischen Leitungen in die Einführöffnungen 20 des Anschlussblockes 10 eingesteckt werden, woraufhin der Deckenanschluss 70 mit der Anschlussdose verbunden werden kann. Anschließend kann eine Deckenleuchte an einem mit dem Deckenanschluss 70 verbundenen Haken 72 (Fig. 9) eingehängt werden.The ceiling connector 70 is easily inserted into a junction box (not shown) that is attached to the ceiling. Beforehand, only the electrical lines have to be plugged into the insertion openings 20 of the connection block 10, whereupon the ceiling connection 70 can be connected to the connection box. A ceiling light can then be attached to a hook 72 ( 9 ) to be mounted.
