Description

Die Erfindung bezieht sich auf einen Zwischenstecker gemäß dem Oberbegriff des Anspruches 1.The invention relates to an adapter plug according to the preamble of claim 1.

Solche bekannte Zwischenstecker weisen meist lediglich einen Anschluß für einen vom Ausgang des Netzgerätes versorgten Ausgang auf, an den Kleinverbraucher, wie elektrische Zahnbürsten, Rasierapparate, Tischstaubsauger, Radios, CD-Player, Walkmans, Komfort- oder Schnurlostelefone u.dgl. anschließbar ist.Such known adapter plugs usually only have a connection for an output supplied by the power supply to the small consumer, such as electric toothbrushes, shavers, table vacuum cleaners, radios, CD players, Walkmans, comfort or cordless telephones and the like. can be connected.

In vielen Bereichen des täglichen Lebens werden elektrische Kleinverbraucher eingesetzt, die sehr oft mit Akkumulatoren für den mobilen Betrieb ausgerüstet sind. Um die den Akkumulator für die unmittelbare Verwendung im geladenen Zustand zu halten, wird ein solches Gerät sehr oft im Ruhezustand vom Netz mittels eines Netzgerätes, z.B. eines in einem Zwischenstecker eingebauten Netzgerätes, gepuffert.Small electrical consumers are used in many areas of daily life, which are very often equipped with batteries for mobile operation. In order to keep the battery charged for immediate use, such a device is very often disconnected from the network by means of a power supply, e.g. a power supply installed in an adapter plug, buffered.

Die Steckdose, in die der Zwischenstecker samt eingebauten Netzgerät eingesteckt ist, ist dabei dauerbelegt und für andere Verbraucher verloren. Im Badezimmerbereich ist dies oft recht unangenehm, da wegen der Vorschrift, daß Steckdosen wenigstens 1m von der nächsten Wasserentnahmestelle entfernt angeordnet sein müssen, meist nur eine Steckdose vorhanden ist. Dazu kommt, daß gerade im Naßbereich jedes herumliegende Kabel als störend empfunden wird.The socket into which the adapter plug including the built-in power supply is plugged in is permanently occupied and lost to other consumers. This is often quite uncomfortable in the bathroom area, because due to the requirement that sockets must be located at least 1m from the nearest water supply point, there is usually only one socket. In addition, every cable lying around is perceived as a nuisance, especially in the wet area.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden.The aim of the invention is to avoid these disadvantages.

Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention this is achieved by the characterizing features of claim 1.

Durch die Merkmale des Anspruches 2 ergibt sich die Möglichkeit, daß auch Schutzkontakt-Netzstecker an den erfindungsgemäßen Zwischensteckers angeschlossen werden können.Due to the features of claim 2, there is the possibility that earthed power plugs can also be connected to the adapter plug according to the invention.

Dabei kann in dem Zwischenstecker ein vollständiges Netzgerät eingebaut sein oder auch nur ein Teil eines solchen Netzgerätes. In letzterem Fall können die weiteren Bauteile des Netzgerätes in einem an den Zwischenstecker angeschlossenen Verbraucher angeordnet sein.In this case, a complete power supply unit can be built into the adapter plug, or only a part of such a power supply unit. In the latter case, the other components of the power supply unit can be arranged in a consumer connected to the adapter.

Durch die Merkmale des Anspruches 3 ergibt sich eine in konstruktiver Hinsicht sehr einfache Lösung, wobei die Übertragung der Energie auf den Verbraucher auf induktivem Wege erfolgt. Dabei kann die Steuerung des Netzgerätes im Verbraucher untergebracht werden, wobei dann in dem Zwischenstecker lediglich die Ladespule vorgesehen zu werden braucht.The features of claim 3 result in a very simple solution in terms of design, the energy being transferred to the consumer by inductive means. The control of the power supply unit can be accommodated in the consumer, only the charging coil then having to be provided in the adapter plug.

Durch die Merkmale des Anspruches 4 können mit üblichen Kleinspannungssteckern versehene Verbraucher an den Zwischenstecker, neben einem mit einem üblichen Netzstecker versehenen Verbraucher, angeschlossen werdenDue to the features of claim 4, consumers provided with conventional low-voltage plugs can be connected to the intermediate plug, in addition to a consumer provided with a conventional mains plug
