Abstract

The present invention relates to a device for converting the mains voltage into a lower voltage, wherein said device comprises a first connector which can be inserted in a mains plug, a second connector which can be inserted in a load as well as a voltage conversion circuit essentially provided between the two connectors. In the device of the present invention, the circuit forms together with the second connector (2) a rigid unit which reduces to a minimum both the electric resistance and the electric connection between said circuit and said second connector (2). The losses and line overloads can thus be practically eliminated.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Umwandlung von Netzspannung (in der Regel 230 V) in Niederspannung (in der Regel "Sicherheitskleinspannung"), bestehend aus einem ersten in eine Netzsteckdose steckbaren Stecker, einem zweiten in einen Verbraucher steckbaren Stecker und einer Schaltung, die zwischen den beiden Steckern zur Spannungsumwandlung angeordnet ist.The invention relates to a device for conversion from mains voltage (usually 230 V) to low voltage (usually "safety extra-low voltage") consisting of a first plug that can be plugged into a mains socket, one second plug into a consumer and one Circuit that connects between the two plugs Voltage conversion is arranged.

Bei bekannten, auf dem Markt befindlichen Vorrichtungen dieser Art ist die Schaltung über eine elektrische Leitung von nicht unerheblicher Länge, z.B. 2 m, mit dem zweiten Stecker verbunden. Diese Lösung hat den Nachteil, daß in der Leitung deutliche Verluste auftreten können, die häufig unerwünscht sind. Auch kann es passieren, daß die Leitung überlastet wird.In known devices on the market Art is the circuit via an electrical line from not inconsiderable length, e.g. 2 m, with the second connector connected. This solution has the disadvantage that in the line significant losses can occur which are often undesirable are. It can also happen that the line is overloaded becomes.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs erwähnte Vorrichtung derart auszubilden, daß Verluste und eventuelle Leitungsüberlastungen so weit wie möglich vermieden werden.The invention is based on the object mentioned Train the device so that losses and possible line overloads avoided as far as possible become.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schaltung mit dem zweiten Stecker eine in sich starre Baueinheit mit möglichst kurzer elektrischer Verbindung zwischen Schaltung und zweitem Schalter mit möglichst kleinem elektrischen Widerstand bildet.This object is achieved in that the Circuit with the second connector is a rigid unit with the shortest possible electrical connection between Circuit and second switch with the smallest possible forms electrical resistance.

Auf diese Weise wird erreicht, daß Verluste und Leitungsüberlastungen praktisch vermieden werden können, letzteres deshalb, weil bei einer kurzen, eingebauten Verbindung der Querschnitt der Verbindung eher entsprechend groß sein kann als bei einer langen, freiliegenden Leitung, die dann unhandlich würde.In this way it is achieved that losses and line overloads can practically be avoided, the latter This is because with a short, built-in connection the Cross-section of the connection can be rather large than with a long, exposed line, which is then unwieldy would.

Als weiterer Vorteil kommt hinzu, daß man besser als im oben erwähnten bekannten Fall zusätzliche Signale (über zusätzliche elektrische Verbindungen) übertragen kann, weil bei der erfindungsgemäßen Vorrichtung die lange Leitung, die bei der bekannten Vorrichtung vorhanden ist, fehlt.Another advantage is that you can do better than in the above known case mentioned additional signals (via additional electrical connections) can transmit, because at the The device according to the invention the long line, which at known device is missing.

Eine Weiterentwicklung der Erfindung besteht darin, daß an der Vorrichtung ein Ein/Ausschalter für die Netzspannung angebracht ist. Der Vorteil dieser Lösung gegenüber der eingangs erwähnten Lösung mit Ein/Ausschalter für die Netzspannung besteht darin, daß der Ein/Ausschalter praktisch immer benutzt wird, wenn der Verbraucher ausgeschaltet werden soll. Im bekannten Fall wird der Ein/Ausschalter häufig nicht benutzt, weil sich die Spannungsumwandlungsvorrichtung an schwer zugänglicher bzw. nicht ohne weiteres sichtbarer Stelle, nämlich entfernt vom Verbraucher, befindet. Man läßt also den Verbraucher häufig eingeschaltet und verbraucht damit nutzlos Energie, oder es wird in primitiver Weise der Netzstecker herausgezogen. Wohl nicht zuletzt aus diesem Grunde haben die bekannten Vorrichtungen häufig gar keinen Ein/Ausschalter.A further development of the invention is that the device an on / off switch for the mains voltage is appropriate. The advantage of this solution compared to the beginning mentioned solution with on / off switch for the mains voltage is that the on / off switch is almost always is used when the consumer is switched off should. In the known case, the on / off switch is common not used because the voltage conversion device in difficult to access or not easily visible Location, namely away from the consumer. You leave that is, the consumer is frequently switched on and consumed thus useless energy, or it becomes the primitive Pulled out the mains plug. Last but not least from this Basically, the known devices often have none On / off switch.

Weiterhin wird vorgeschlagen, daß der zweite Stecker mindestens dreipolig ist. Zur Übertragung zusätzlicher Signale ist diese Lösung sinnvoll.It is also proposed that the second connector at least is three-pole. For the transmission of additional signals this solution makes sense.

Sodann wird vorgeschlagen, daß an der Vorrichtung eine Einrichtung zur Anzeige des Betriebszustandes vorgesehen ist.Then it is proposed that a device on the device is provided to display the operating state.

Schließlich wird vorgeschlagen, daß der zweite Stecker leicht von dem Rest der Baueinheit entfernbar und gegebenenfalls durch einen anderen austauschbar ist. Auf diese Weise ist es möglich, die erfindungsgemäße Vorrichtung verschiedenen Verbrauchern bequem anzupassen. Finally, it is proposed that the second connector easily removable from the rest of the assembly and if necessary is interchangeable with another. In this way it is possible to different the device according to the invention Easily adapt to consumers.
