Description

Die Erfindung betrifft eine Steckdose bestehend aus einem Isolierstoffsockel mit einem mittig angeordneten Buchsenpaar, welches im Eingriff mit Steckerstiften eines Steckers einen Schaltkontakt bildet, einer Abdeckplatte aus Isolierstoff für die Steckdose und einem mit dem Isolierstoffsockel elektrisch und mechanisch verbindbaren Modul für Zusatzfunktionen gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a socket consisting of a Insulating base with a pair of sockets in the middle, which engages with connector pins of a connector forms a switch contact, a cover plate made of insulating material for the socket and one with the insulating base electrically and mechanically connectable module for Additional functions according to the preamble of claim 1.

Um einen Isolierstoffsockel von Steckdosen für Zusatzfunktionen in seiner Höhe unverändert zu belassen, ist aus der EP-A-0 654 864 ein elektrotechnisches Installationsgerät, beispielsweise in Form einer Steckdose und damit gemäß dem Oberbegriff des Anspruches 1 in Modulbauweise bekannt, bei der durch das von der Bauwerksseite der Steckdose her an deren Isolierstoffsockel ansteckbare Modul der Steckdose Zusatzfunktionen gegeben werden. Die elektrische Kontaktgabe für das steckbare Modul wird jeweils durch gefederte Kontakte erzielt, wenn ein Steckerstift eines Steckers in das Buchsenpaar der Steckdose eingeführt wird.To an insulating base of sockets for additional functions to remain unchanged in height is from the EP-A-0 654 864 an electrotechnical installation device, for example in the form of a socket and thus according to The preamble of claim 1 is known in modular design, at by the from the building side of the socket whose insulating base is pluggable module of the socket Additional functions are given. The electrical contact spring-loaded contacts are used for the pluggable module achieved when a connector pin of a connector in the Socket pair of the socket is inserted.

Die DE-U-295 07 448 zeigt eine Steckdose, bestehend aus einem Isolierstoffsockel mit einem mittig angeordneten Buchsenpaar, welches im Eingriff mit Steckerstiften eines Steckers einen Schaltkontakt bildet. Dort ist vorgesehen, neben dem Isolierstoffsockel einen Freiraum zu belassen bzw. diesen Freiraum so zu nutzen, daß auf einer Platte angeordnete elektronische Bauelemente hineinragen können. Problematisch sind jedoch die für die Verbindung zwischen den eigentlichen Überspannungsschutz-Bauelementen und den elektrischen Anschlüssen der Schutzkontakt-Steckdose notwendigen flexiblen Leitungen. Dies führt zu wesentlichen Nachteilen hinsichtlich des Montageaufwands und der Gefahr von Verpolungen. DE-U-295 07 448 shows a socket consisting of an insulating base with a central one Pair of sockets, which in engagement with connector pins Plug forms a switching contact. There is provided to leave a space next to the insulating base or to use this free space so that arranged on a plate can protrude electronic components. However, those for the connection between are problematic the actual surge protection components and the electrical connections of the protective contact socket necessary flexible lines. This leads to essentials Disadvantages in terms of assembly effort and risk of reverse polarity.

Weiterhin ist aus der DE-OS 37 36 945 eine Steckdose mit Zusatzmodul bekannt, bei der an die Unterseite des Isolierstoffsockels die Oberseite des Zusatzmoduls angebracht ist. Dabei ist der Isolierstoffsockel dahingehend geändert worden, daß er gekürzte Abstandsstege besitzt und mit diesen Abstandsstegen am Tragring angebracht ist. Ferner kann eine Anhebung des äußeren Steckertopfes erfolgen. Das Zusatzmodul wird hier ebenso wie bei dem Gegenstand von EP 0 654 864 mittels klammerartig ausgebildeter Rasthaken an Vorsprüngen des Isolierstoffsockels unmittelbar an diesem anliegend verankert. Durch die o.g. Kürzung der Abstandsstege und dem damit verbundenen Anheben des Isolierstoffsockels kann der genormte Mindestabstand zwischen der Steckdose und dem Dosenboden einer Unterputzdose eingehalten werden. Auf der Leiterplatte des Zusatzmoduls sind die Bauelemente einer Überspannungsschutzeinrichtung so positioniert, daß sie in Freiräumen Platz finden können, die sich ebenso wie beim - Gegenstand von EP-0 654 864 zwischen dem Boden der Unterputzdose und der diesem Boden gegenüberliegenden Unterfläche des Isolierstoffsockels befinden. Dabei ist zu beachten, daß der Freiraum zwischen dem Boden der Unterputzdose und der diesem Boden zugewandten Fläche des Isolierstoffsockels in seiner Höhe aufgrund der vorgeschriebenen Abmessungen der Unterputzdose und der erforderlichen Abmessung des Isolierstoffsockels begrenzt und damit nicht beliebig vergrößerbar ist.Furthermore, from DE-OS 37 36 945 an outlet with Additional module known, at the bottom of the insulating base the top of the additional module is attached. The base of the insulating material has been changed that he has shortened spacers and with these Spacers is attached to the support ring. Furthermore, a Lift the outer connector pot. The additional module here as well as the subject of EP 0 654 864 by means of clip-like locking hooks on projections of the insulating base directly adjacent to this anchored. Through the above Reduction of the spacer bars and the associated lifting of the insulating base can standardized minimum distance between the socket and the The bottom of a flush-mounted box can be observed. On the PCB of the additional module are the components of a Surge protection device positioned so that it in Free space that can be found just like the - Subject of EP-0 654 864 between the bottom of the flush-mounted box and the lower surface opposite this floor of the insulating base. It should be noted that the space between the bottom of the flush-mounted box and the this floor facing surface of the insulating base in its height due to the prescribed dimensions of the Flush-mounted box and the required dimension of the insulating base limited and therefore not expandable is.

Es hat sich nun gezeigt, daß derartig gestaltete, jeweils zwischen Isolierstoffsockel und Boden der Unterputzdose befindende Module für Zusatzfunktionen nicht allen Anforderungen in der Praxis genügen, insbesondere wenn die für die Realisierung der Zusatzfunktionen benötigten diskreten Bauelemente so groß sind, daß diese nicht in den vorhandenen Freiräumen untergebracht werden können.It has now been shown that such a design, in each case between the insulating base and the bottom of the flush-mounted box modules for additional functions not all requirements in practice are sufficient, especially if those for the implementation of the additional functions required discrete Components are so large that they are not in the existing ones Free spaces can be accommodated.

Der Erfindung liegt daher zunächst das Problem zugrunde, die aus EP A1 0 654 864 bekannte Steckdose derart auszugestalten, daß auch voluminöse Module im zur Verfügung stehenden Raum unter Einhaltung der erforderlichen Innenabmessungen einer Steckdose mit Isolierstoffsockel untergebracht werden können.The invention is therefore initially based on the problem that To design the socket known from EP A1 0 654 864 in such a way that even voluminous modules are available standing space while observing the required internal dimensions a socket with an insulating base can be.

Dieses Problem wird, ausgehend von einer Steckdose gemäß dem Oberbegriff gemäß Anspruch 1 dadurch gelöst, daß der Isolierstoffsockel asymmetrisch zum Buchsenpaar angeordnet ist und daß ein dadurch neben dem Isolierstoffsockel geschaffener und sich über die Höhe des Isolierstoffsockels erstreckender Freiraum für die Unterbringung eines Teiles des Moduls genutzt wird. Weiterhin besitzt der Isolierstoffsockel mindestens eine Ausnehmung an seiner Unterseite zur Aufnahme von Bauelementen des Moduls.This problem is caused by an outlet according to the Preamble according to claim 1 solved in that the Insulation base arranged asymmetrically to the pair of sockets is and that a thereby created next to the insulating base and the height of the insulating base extending space for the accommodation of a part of the module is used. Furthermore, the insulating base has at least one recess on its underside to accommodate components of the module.

Durch die erfindungsgemäße Gestaltung der Steckdose ist die Möglichkeit gegeben, entsprechend groß dimensionierte Bauelemente eines Moduls unterzubringen, ohne die Höhe des Isolierstoffsockels ändern zu müssen bzw. durch Kürzung der Abstandsstege entsprechende konstruktive Aufwendungen zu verursachen. Zweckmäßigerweise sind die Gestaltung des vorgenannten Freiraumes einerseits und die Gestaltung der hierin einzubringenden Bauteile des Moduls in ihrer Formgebung andererseits aufeinander abgestimmt, um den vorhandenen Platz des Freiraumes optimal ausnützen zu können. Die Bemühungen beim Stand der Technik gehen dagegen in die Richtung, die benötigten Bauelemente entweder so klein zu machen, daß sie bei normalen, d.h. unveränderten Isolierstoffsockeln in sowieso vorhandene Ecken bzw. Freiräume passen. Oder man ordnete dagegen die großen Bauelemente auf der Unterseite der Leiterplatte an, womit die Bauhöhe für das Modul erhöht wurde. Dies erlaubten entsprechende Zusatzmaßnahmen, wie beispielsweise die o.g. Verkürzung der Abstandsstege zum Tragring (DE-OS 37 36 945).Due to the design of the socket according to the invention Possibility given correspondingly large dimensions To accommodate components of a module without the height of the Need to change the insulating base or by reducing the Spacer webs corresponding design expenses cause. The design of the aforementioned free space on the one hand and the design of the Components of the module to be incorporated therein in their shape on the other hand matched to the existing one To be able to make optimal use of space. The However, efforts in the prior art go into the Direction, the components required are either too small make that with normal, i.e. unchanged insulating base in existing corners or open spaces anyway fit. Or you ordered the large components the underside of the circuit board, with which the overall height for the module was increased. This allowed corresponding Additional measures, such as the above Shortening the Spacers to the support ring (DE-OS 37 36 945).

Gemäß der Erfindung beinhaltet das Modul eine Überspannungsschutzeinrichtung, welche eine parallel zum Boden des Isolierstoffsockels verlaufende Leiterplatte mit mindestens zwei Ecken aufweist, einschließlich der im einzelnen in ihrer Anordnung erläuterten Varistoren. Dies ergibt den Vorteil, daß man auch große Varistoren zusammen mit den übrigen Bauelementen der Überspannungsschutzeinrichtung mit vorsehen kann. Die Leiterplatte kann nur an einer Seite, nämlich der dem Isolierstoffsockel zugewandten Seite, bestückt werden. Eine Bestückung der Leiterplatte auf beiden Seiten ist nicht erforderlich. Da es somit nicht notwendig ist, an der dem Isolierstoffsockel abgewandten Unterseite der Leiterplatte Bauelemente des Überspannungsschutzes, insbesondere auftragende Varistoren oder Gasableiter unterzubringen, ergibt sich der aufgabengemäße Vorteil der Raumersparnis. Auch kann man die an der Unterseite des Isolierstoffsockels befindlichen elektrischen Elemente der Leiterplattenoberseite klein halten. Die großen Bauelemente dieses Überspannungsschutzes, nämlich die Varistoren, sind dagegen in den Ecken der Leiterplatte angeordnet und ragen in den geschaffenen Freiraum neben dem Isolierstoffsockel hinein.According to the invention, the module contains an overvoltage protection device, which is parallel to the bottom of the PCB with a minimum of has two corners, including the one in detail their arrangement explained varistors. This gives the Advantage that you can also large varistors together with the other components of the surge protection device with can provide. The circuit board can only on one side, namely the side facing the insulating base, be equipped. A PCB assembly on both Pages are not required. Because it is not necessary is on the underside facing away from the insulating base the circuit board components of surge protection, in particular applied varistors or gas discharge tubes to accommodate, the task-related advantage of Space saving. You can also see the bottom of the Electrical elements of the insulating base Keep the top of the PCB small. The big components this overvoltage protection, namely the varistors on the other hand, arranged and protruding in the corners of the circuit board in the created space next to the insulating base into it.

Es wirken also die Ausbildung des Steckdosensockels mit Schaffung des Freiraumes einerseits und die zugehörige Ausgestaltung des Moduls, insbesondere in Form einer Überspannungsschutzeinrichtung mit zwei relativ großen Varistoren, zur Lösung der erfindungsgemäßen Aufgabe bei einem Modul zum Überspannungsschutz zusammen.So the formation of the socket base also contribute Creation of free space on the one hand and the associated Design of the module, in particular in the form of an overvoltage protection device with two relatively large varistors, to achieve the object of the invention in a Surge protection module together.

Die Ausgestaltung nach Anspruch 4 ergibt den Vorteil, daß sowohl der Isolierstoffsockel als auch die Überspannungsschutzeinrichtung gegen Beschädigung bei der Lagerung und beim Transport geschützt ist, zudem kann hiermit auf einfache Art und Weise ein Berührungsschutz realisiert werden.The embodiment according to claim 4 gives the advantage that both the insulating base and the overvoltage protection device against damage during storage and is protected during transport, moreover it can be easily used Protection against accidental contact.

Die Ausgestaltungen der Steckdose nach den Ansprüchen 5, 6 und 7 weisen den Vorteil auf, daß der Zusammenbau von Überspannungsschutzeinrichtung und Isolierstoffsockel mit Hilfe der Kappe schnell und mittels einfacher Handgriffe vorgenommen werden kann.The configurations of the socket according to claims 5, 6 and 7 have the advantage that the assembly of surge protective device and insulating base with the help the cap quickly and easily done can be.

Bei Anordnung von Überspannungsschutzelementen ist häufig eine optische Anzeige dahingehend vorgesehen, ob die Überspannungsschutzelemente einer solchen Überspannungsschutzeinrichtung noch in Ordnung sind. Entsprechende Anzeigemittel sind in der Regel in einer Ecke der Leiterplatte'angeordnet. Um nun im vorliegenden Fall durch die Abdeckplatte der Steckdose hindurch eine entsprechende optische Signalgebung nach außen zu ermöglichen, einschließich einer klaren Unterscheidung unterschiedlicher Signale, sind die Merkmale des Anspruches 9 vorgesehen. Hierdurch können von den in den Eckenbereichen befindlichen Varistoren relativ kurze Leitungen durch die Abdeckplatte hindurch nach oben geführt werden. Damit befinden sich die Signallampen an zwei im Abstand voneinander befindlichen Ecken der Steckdose. Sie sind hiermit von der Raumseite her sowohl gut zu erkennen als auch vor allen Dingen gut voneinander zu unterscheiden. Selbst bei grellem Licht ist für den Benutzer durch die räumliche Trennung, beispielsweise einer roten von einer grünen Anzeige, die Erkennbarkeit jederzeit gegeben.When arranging surge protection elements is common an optical display is provided as to whether the surge protection elements such a surge protection device are still fine. Corresponding display means are usually arranged in a corner of the circuit board. To now in the present case through the cover plate a corresponding optical signaling through the socket to allow outside, including a clear one Distinguishing different signals are the characteristics of claim 9 provided. As a result, of the in the Varistors located in corner regions have relatively short lines passed up through the cover plate become. This means that the signal lamps are located on two in the Distance from the corners of the socket. she are both clearly visible from the room side as well as differentiating from each other. Even in bright light, the user is able to use the spatial separation, for example a red from a green display, recognizability given at all times.

Vorteilhafterweise wird durch eine Anordnung der Sicherungen räumlich benachbart zu den Varistoren ferner eine kompakte, raumsparende Gestaltung der erfindungsgemäßen Steckdose und eine optimale Wärmeübertragung vom Varistor auf diese thermischen Sicherungen erreicht.An arrangement of the fuses is advantageous a compact, spatially adjacent to the varistors space-saving design of the socket and optimal heat transfer from the varistor to this thermal fuses reached.

Durch die Merkmale des Anspruches 11 wird die räumliche Unterbringung der Varistoren im Freiraum und damit die Ausnützung des geschaffenen Freiraumes innerhalb der Unterputzdose oder der Kunststoffkappe weiter verbessert.Due to the features of claim 11, the spatial Housing the varistors in the free space and thus the Exploitation of the space created within the flush-mounted box or the plastic cap further improved.
