Description

Die Erfindung betrifft eine Mehrfachsteckdose der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a multiple socket of the type mentioned in the preamble of claim 1.

Zum Anschliessen von elektrischen Geräten an das Netz sind nur solche Steckvorrichtungen zugelassen, die die jeweiligen Sicherheitsvorschriften erfüllen. Die wohl häufigste Art den Bedienenden vor gefährlichen Berührungsspannungen zu schützen, ist die Verwendung einer dreipoligen Steckvorrichtung. Der als Schutzkontakt wirkende dritte Pol sorgt dafür, dass bei Isolationsmängeln auftretende Fehlerströme gegen die Erde abgeleitetwerden. Der Aufbau einer derartigen Schutzkontakt-Steckvorrichtung ist in den verschiedenen Ländern zum Teil recht unterschiedlich. In Deutschland ist die sogenannte Schuko-Steckvorrichtung genormt.Only connectors that meet the relevant safety regulations are permitted to connect electrical devices to the network. The most common way to protect the operator from dangerous touch voltages is to use a three-pin connector. The third pole, which acts as a protective contact, ensures that fault currents occurring in the event of poor insulation are discharged against the earth. The structure of such a protective contact plug device is sometimes quite different in the different countries. In Germany, the so-called Schuko plug device is standardized.

Eine weitere, in der Häufigkeit ihrer Anwendung ständig zunehmende Schutzmöglichkeit ist die Schutzisolierung. Durch die Isolierung wird von vornherein das Entstehen gefährlicher Fehlerströme oder Fehlerspannungen im Berührungsbereich des Bedienenden verhindert. Bei diesen Steckvorrichtungen kann dementsprechend, der als Schutzkontakt dienende dritte Pol enffallen, so dass eine wesentlich kleinere und handlichere Zweipol-Steckvorrichtung verwendet werden kann. Steckvorrichtungen dieser Art sind in Deutschland unter dem Namen Euro-Steckvorrichtung bekannt. Ein hierzu gehörigerZweipol-Stecker passt zwar in eine Schutzkontakt-Steckdose, ein Schutzkontakt-Stecker darf jedoch nicht in eine Zweipol-Steckdose passen, da hier der Schutzkontakt fehlt. Zweipol-Steckdosen sind deshalb im allgemeinen mit kleineren Stecköffnungen zur Aufnahme der Steckerstifte versehen, durch die die dickeren Steckerstifte eines Schutzkontakt-Steckers nicht hindurchpassen.Another type of protection that is constantly increasing in frequency of use is protective insulation. The insulation prevents the occurrence of dangerous fault currents or fault voltages in the contact area of the operator from the outset. Accordingly, in these plug-in devices, the third pole serving as a protective contact can be omitted, so that a much smaller and handier two-pole plug-in device can be used. Plug devices of this type are known in Germany under the name Euro plug device. A two-pin plug belonging to this fits into a protective contact socket, but a protective plug must not fit into a two-pin socket, since the protective contact is missing here. Two-pin sockets are therefore generally provided with smaller plug openings for receiving the plug pins, through which the thicker plug pins of an earthed plug do not fit.

Der steigende Anteil der schutzisolierten Geräte hat dazu geführt, dass auch der Bedarf an Zweipol-Steckdosen gestiegen ist. Diese sind im Vergleich zu Schutzkontakt-Steckdosen nicht nur in ihrem Aufbau einfacherer und damit billiger sondern vor allem kleiner, so dass auf der gleichen Fläche etwa die doppelte Anzahl montiert werden kann. Es werden deshalb bereits Steckdosen-Anordnungen gebaut, insbesondere beweglicher Art, wie z.B. Tischsteckdosen, bei denen neben Schutzkontakt-Steckdosen angeordnet sind. Um nun zu verhindern, dass an einigen Stellen eines installierten Hauses nur Zweipol-Steckdosen zur Verfügung stehen, sieht ein deutscher Normentwurf vor, dass bei der Montage von maximal zwei Zweipol-Steckdosen mindestens eine Schutzkontakt-Steckdose anzubringen ist.The increasing proportion of insulated devices has led to an increase in the need for two-pin sockets. Compared to earthed sockets, these are not only simpler in terms of their construction and therefore cheaper, but above all smaller, so that roughly twice the number can be installed on the same area. Socket arrangements are therefore already being built, in particular of a movable type, such as Table sockets, which are arranged next to earthed sockets. In order to prevent that only two-pole sockets are available in some places of an installed house, a German draft standard stipulates that at least one protective contact socket must be attached when installing a maximum of two two-pole sockets.

Auch wenn der Normentwurf zunächst nur für einen territorial begrenzten Bereich gilt, so besitzt doch die ihm zugrundeliegende Forderung Allgemeingültigkeit. Die Erfindung geht nun von der Überlegung aus, dass der Installateur am sichersten dadurch zur Einhaltung bestimmter Vorschriften odersachgerechter Empfehlungen zu bewegen ist, wenn das zur Verfügung stehende Installationsmaterial in optimaler Weise so vorbereitet ist, dass die unerwünschten Kombinationen gar nicht realisierbar sind.Even if the draft standard initially only applies to a territorially limited area, the underlying requirement is still generally applicable. The invention is now based on the consideration that the installer can be most safely moved to comply with certain regulations or appropriate recommendations if the available installation material is optimally prepared in such a way that the undesired combinations cannot be implemented at all.

Es ist weiterhin zu berücksichtigen, dass sich die Zahl der Geräte mit Zweipol-Stecker insbesondere in den letzten Jahren stark erhöht hat, so dass bereits erstellte Installationen diesem Umstand kaum Rechnung tragen. Es wird deshalb relativ oft erforderlich sein, bereits vorhandene Einrichtungen den neuen Gegebenheiten anzupassen, also z.B. bereits installierte Unterputzdosen mit einer Mehrfachsteckdose zu versehen.It should also be borne in mind that the number of devices with a two-pin connector has increased significantly in recent years, so that installations that have already been made hardly take this into account. It will therefore be relatively often necessary to adapt existing facilities to the new conditions, e.g. to provide already installed flush-mounted sockets with a multiple socket.

Die DE-A-2 344 412 beschreibt eine für UP-Einbau vorgesehene Doppelsteckdose, deren Sockel Doppelkontaktfedern aufweist. Sie ermöglicht nebeneinander die Anordnung von entweder zwei Schuko- oder zwei Zweipolsteckern; nicht jedoch deren Kombination.DE-A-2 344 412 describes a double socket provided for flush mounting, the base of which has double contact springs. It enables the arrangement of either two Schuko or two two-pin plugs next to each other; but not their combination.

Aufgabe der Erfindung ist es, eine Mehrfachsteckdose zu schaffen, die nebeneinander sowohl Schutzkontakt-Steckdosen wie auch Zweipol-Steckdosen umfasst und die unter Verwendung einer vorhandenen Unterputzdose montierbar ist.The object of the invention is to provide a multiple socket that includes both protective contact sockets as well as two-pin sockets next to each other and that can be installed using an existing flush-mounted socket.

Diese Aufgabe wird durch die in Anspruch 1 genannten Merkmale gelöst. Weitere Ausgestaltungen und Fortbildung der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features mentioned in claim 1. Further refinements and developments of the invention are characterized in the subclaims.

Durch die unveränderbare Ausbildung der Abdeckplatte sowohl mit einem Schutzkontakt-Stecktopf wie auch mit einem Zweipol-Stecktopf (-Nichtschutzkontaktstecktopf) ist sichergestellt, dass die Montage einer Schutzkontakt-Steckdose nicht versäumt wird. Durch die Ausbildung eines besonderen Stecksockels, der Kontaktteile besitzt, die nebeneinander das Kontaktieren sowohl eines Schutzkontakt-Steckers wie auch mindestens eines Zweipol-Steckers ermöglichen, gelingt es die Mehrfachsteckdose mit Hilfe einer Unterputzdose aufzubauen.The unchangeable design of the cover plate with a protective contact socket as well as a two-pole socket (non-protective contact socket) ensures that the installation of a protective contact socket is not missed. Through the formation of a special plug-in base, which has contact parts which, next to each other, make it possible to contact both a protective contact plug and at least one two-pin plug, the multiple socket can be set up using a flush-mounted socket.

Die geringe Grösse der Zweipol-Stecker erlaubt es, in derAbdeckplatte mehr als einen Zweipol-Stecktopf auszubilden. Bei mehreren Zweipol-Stecktöpfen können diese, je nach Ausbildung des Stecksockels, ein- oder mehrseitig zum Schutzkontakt-Stecktopf angeordnet werden. Der Abstand von zwei gleichpoligen, nebeneinanderliegenden Steckbuchsen des Zweipol-Steckers muss nur geringfügig grösser sein als seine Breite.The small size of the two-pole plug allows more than one two-pole socket to be formed in the cover plate. In the case of several two-pin plug-in pots, depending on the design of the plug-in base, these can be arranged on one or more sides of the protective contact plug-in pot. The distance from two same-pole, adjacent sockets of the two-pin connector only has to be slightly larger than its width.

Die noch zulässige Breite des Stecksockels ist in den Prüfungsanforderungen vorgeschrieben. Wird so ein entsprechend breiter Stecksockel verwendet so ist es zweckmässig, seine Steckbuchsen in einer Ebene anzuordnen. Bei einem in der Unterputzdose montierten Stecksockel werden in diesem Fall die Steckbuchsen unterhalb der Oberflächenebene der Einbauwand zu liegen kommen. Dementsprechend sind auch die in der Abdeckung ausgebildeten Stecktöpfe gleich tief.The still permissible width of the plug-in base is prescribed in the test requirements. If such a correspondingly wide plug-in base is used, it is expedient to arrange its sockets in one plane. In this case, with a plug-in base mounted in the flush-mounted socket, the sockets will come to lie below the surface level of the installation wall. Accordingly, the plug formed in the cover pots the same deep.

In den gleich tiefen Stecktöpfen haben die zwei nebeneinanderliegenden Zweipol-Stecker eine zu geringe Griff-Fläche beim Ein- und Ausstecken in den ca. 17,5 mm tiefen Stecktopf, deshalb ist es günstiger die Steckbuchsen der Zweipol-Steckdosen über die Oberfläche der Einbauwand herausragen zu lassen.In the same-deep plug-in pots, the two adjacent two-pin plugs have too little grip area when plugging in and unplugging the approx. 17.5 mm deep plug-in pot, which is why it is cheaper to project the sockets of the two-pin sockets over the surface of the installation wall allow.

Durch die in verschiedenen Ebenen liegenden Kontakte verlagen sich auch die Auflageflächen für die verschiedenen Steckerarten. So ist der Zweipol-Stecktopf durch eine zur Oberfläche der Einbauwand parallel liegende Zwischenwand in seiner Höhe stark reduziert. Die am Stecksockel befestigten Buchsen kommen bei montierter Steckdose in dem Raum unterhalb der Zwischenwand zu liegen.Due to the contacts located on different levels, the contact surfaces for the different connector types have also shifted. The height of the two-pin socket is greatly reduced by an intermediate wall lying parallel to the surface of the installation wall. The sockets attached to the plug base come to rest in the room below the partition when the socket is installed.

Um die Zahl der Teile zu reduzieren und die Montage zu erleichtern ist es zweckmässig gleichpolige Steckbuchsen des Stecksockels einstückig und zwar fürdie Verwendung in mehreren Ebenen liegend, also stufig versetzt oder in einer Ebene liegend auszubilden. Vorteilhafterweise sind an den einstückig ausgebildeten Steckbuchsen auch Elemente zum Leitungsanschluss und zur Eigenhalterung im Sockel angeformt.In order to reduce the number of parts and to facilitate assembly, it is expedient to design the same-pole sockets of the plug base in one piece, namely for use in several levels, that is to say staggered or in one level. Advantageously, elements for line connection and self-holding in the base are also integrally formed on the one-piece plug sockets.

Weitere Vorteile des Erfindungsgegenstandes sind anhand von Ausführungsbeispielen der Erfindung in den Zeichnungen dargestellt und werden im Folgenden näher erläutert.Further advantages of the subject matter of the invention are illustrated in the drawings using exemplary embodiments of the invention and are explained in more detail below.

  • Figur 2 : Eine Mehrfachsteckdose mit einem Stecksockel, bei dem gleichartige Kontaktteile auf mehrere Ebenen stufig verteilt sind.
  • Figur 3 : Ein einstückig hergestelltes Kontaktteil sowohl für Zweipol- wie auch für Schutzkontakt-Stecker.

  • Figure 1: A multiple socket with a plug base, in which the same contact parts are arranged in one plane.
  • Figure 2: A multiple socket with a plug base, in which the same contact parts are distributed on several levels.
  • Figure 3: A one-piece contact part for both two-pin as well as earthing contact plug.

Die in den Figuren 1 und 2 dargestellte Mehrfachsteckdose besteht aus einer Abdeckplatte 1, einem Stecksockel 4, einer Unterputzdose 6 und einem Tragring 13. In der Abdeckplatte 1 sind ein Schutzkontakt-Stecktopf 2 für einen Schutzkontakt-Stecker und ein Zweipol-Stecktopf 3 für zwei Zweipol-Stecker ausgebildet. Abdeckplatte 1 und Stecksockel 4 sind so aufeinander abgestimmt, dass unterhalb der Stecköffnungen 9, 10 jeweils die zugehörigen Steckbuchsen angeordnet sind. Die am Stecksockel befestigten Steckbuchsen sind in den Figuren ebensowenig dargestellt wie die zur Schutzkontakt-Steckdose gehörigen Schutzkontakte, da es sich hierbei um bekannte Anordnungen handelt.The multiple socket shown in Figures 1 and 2 consists of a cover plate 1, a socket 4, a flush-mounted socket 6 and a support ring 13. In the cover plate 1 are a protective contact socket 2 for a protective contact plug and a two-pin socket 3 for two Two-pin connector designed. Cover plate 1 and plug-in base 4 are matched to one another in such a way that the associated plug sockets are arranged below the plug openings 9, 10. The sockets attached to the plug base are shown in the figures as little as the protective contacts belonging to the protective contact socket, since these are known arrangements.

Durch Vergleich der Figuren 1 und 2 wird deutlich, dass sowohl die Gestaltung der Abdeckplatte 1 wie auch des Stecksockels 4 von der Festlegung der Tiefe der Stecktöpfe abhängig ist. In einem Stecksockel mit maximal zulässiger Breite ist es möglich, alle Steckbuchsen in einer gemeinsamen Ebene liegend unterzubringen. In eingebautem Zustand der Mehrfachsteckdose liegen damit alle Steckbuchsen unterhalb der Oberflächenebene der Wand 5. Dementsprechend sind auch der Schutzkontakt-Stecktopf 2 und der Zweipol-Stecktopf 3 gleich tief, d.h. die Anschlagebenen 11, 12a für die Stecker liegen auf gleicher Höhe.By comparing FIGS. 1 and 2, it becomes clear that both the design of the cover plate 1 and of the plug-in base 4 depend on the definition of the depth of the plug-in pots. In a plug-in base with a maximum permissible width, it is possible to accommodate all sockets lying on a common level. When the multiple socket is installed, all of the sockets are below the surface level of wall 5. Accordingly, the protective contact socket 2 and the two-pole socket 3 are of the same depth, i.e. the stop levels 11, 12a for the plug are at the same height.

Andere Verhältnisse ergeben sich bei der in Figur 2 dargestellten, erheblich verringerten Tiefe des Stecktopfes für die Zweipol-Steckdosen mit abgestuftem Stecksockel 4b. Die Lage der Buchsen muss sich deshalb auf verschiedene Ebenen verteilen, um die gleiche Zahl von Steckern kontaktieren zu können. Während die Steckbuchsen für die Schutzkontakt-Steckdose unterhalb der Oberflächenebene der Zimmerwand 5 angeordnet sein können, müssen alle oder zumindest ein Teil der zu den Zweipol-Steckdosen gehörigen Steckbuchsen über die Oberflächenebene hinausragen. Hierzu ist der Zweipol-Stecktopf 3b durch eine Zwischenwand 7 in seiner Höhe so reduziert, dass sich unterhalb der Zwischenwand 7 ein Raum 14 ausbildet, in den die Steckbuchsen hineinragen können.Other conditions result from the considerably reduced depth of the plug socket for the two-pole sockets with stepped plug base 4b shown in FIG. 2. The position of the sockets must therefore be distributed over different levels in order to be able to contact the same number of plugs. While the sockets for the protective contact socket can be arranged below the surface level of the room wall 5, all or at least some of the sockets belonging to the two-pin sockets must protrude beyond the surface level. For this purpose, the height of the two-pin plug receptacle 3b is reduced by an intermediate wall 7 such that a space 14 is formed below the intermediate wall 7, into which the sockets can protrude.

Wie Figur 3 erkennen lässt, sind gleichpolige Buchsen 8a, b, c, die zu der Schutzkontakt-Steckdose und den beiden Zweipol-Steckdosen gehören, einstückig ausgeführt. Je nach ihrer Verwendung in einem Stecksockel 4a nach Figur 1 oder in einem Stecksockel 4b nach Figur 2 hegen die Steckbuchsen 8 in einer Ebene oder sind stufig versetzt auf mehrere Ebenen verteilt. Den Steckbuchsen 8 können auch noch Elemente zum Leitungsanschluss und zur Eigenhalterung im Sockel angeformt sein, was in der Zeichnung nicht dargestellt ist.As can be seen in FIG. 3, same-pole sockets 8a, b, c, which belong to the protective contact socket and the two two-pin sockets, are made in one piece. Depending on their use in a plug-in base 4a according to FIG. 1 or in a plug-in base 4b according to FIG. 2, the sockets 8 are in one level or are staggered on several levels. The sockets 8 can also be molded on elements for line connection and self-holding in the base, which is not shown in the drawing.

Durch die geringe Tiefe des Zweipol-Stecktopfes 3b ist es nicht möglich, schon auf Grund seiner Form, ein Einstecken von Schutzkontakt-Steckern zu verhindern. Um trotzdem unzulässige Steckungen zu vermeiden, sind die Stecköffnungen 9 mit so geringem Durchmesser versehen, dass Stekkerstifte von Schutzkontakt-Steckern nicht hindurchpassen.Due to the shallow depth of the two-pin socket 3b, it is not possible, due to its shape alone, to prevent the plugging of protective earth plugs. In order to avoid inadmissible plug connections nevertheless, the plug openings 9 are provided with such a small diameter that plug pins of protective contact plugs do not fit through.

Da die in Figur 2 dargestellte Abdeckplatte 1 b ebenso wie die Abdeckplatte 1 a einen Schutzkontakt-stecker und zwei Zweipol-Stecker aufnehmen muss, stimmt sie auch in ihren Abmessungen mit dieser in etwa überein. Das bedeutet aber, dass die Stecktöpfe 2, 3b über den Rand der Unterputzdose 6b hinausragen.Since the cover plate 1 b shown in FIG. 2, like the cover plate 1 a, has to accommodate a protective contact plug and two two-pole plugs, its dimensions are also approximately the same. However, this means that the receptacles 2, 3b protrude beyond the edge of the flush-mounted box 6b.
