Definitions
- the invention relates to a switchable power connector, in particular a composed of switchable power connector and a flexible arm device.
- a switchable socket essentially consists of a socket and a switch connected to the socket.
- the socket can be embedded in a wall, for example, or it may be a secondary outlet, which is plugged into a recessed in a wall outlet.
- Switchable sockets or power strips are usually used to disconnect electrical devices from the mains. Many electrical devices consume power even when turned off when the device is in a standby state. By using a switchable socket so power consumption of a device can be prevented in the off state.
- the switch can be connected to the socket by means of a cable, the cable being a conventional power cable suitable for laying on the ground.
- the cable usually has a relatively short length, so that when the socket is plugged in e.g. behind furniture is the switch is difficult to access.
- the remote-controlled socket may, for example, be a remotely operable socket which contains a transmitting unit and a receiving unit arranged in the socket.
- the remote-controlled socket has a number of disadvantages.
- the necessity of providing a transmitting and receiving unit leads to an increased complexity and a consequent error-proneness compared to a wired system.
- the remote control is usually battery operated, ie there is a need to replace the Batteries after their lifetime.
- the dimensions of a remote control compared to a wired switch are usually large and there is a need to store the remote control.
- Object of the present invention is to provide a switchable power plug, which has a simple structure and ensures easy accessibility of the switch, regardless of the position of the power plug.
- the present invention provides a switchable power plug, comprising: a switch contact, which is actuated by a switch, an arm attached to the power plug, at the end of which the switch is arranged, characterized in that the arm has a rigidity, which allows the arm to maintain any shape regardless of its orientation.
- the attached to the power plug flexible arm can have different lengths.
- the length of the arm is preferably in a range of 30cm to 150cm, in particular, the dimensions of the arm may be, for example, 30cm, 60cm, 90cm, 120cm or 150cm.
- the arm has, according to a preferred embodiment, a cylindrical cross-section. However, another shape of the cross section is also possible.
- the arm here consists of an inner layer and an outer layer.
- the inner layer of the arm has a higher rigidity than the outer layer of the arm.
- the inner layer consists of a material of a given stiffness, which can be bent into any shape and maintains this shape regardless of its orientation.
- the material of the inner layer may be a conductive material, such as a metal wire, which connects the switch disposed at the end of the arm to the circuit.
- the inner layer may be formed of a bendable material, wherein additionally a current carrying wire is arranged, which, like describe above the switch arranged at the end of the arm connects to the circuit.
- the outer layer of the arm consists of a plurality of spaced-apart elements, wherein the inner layer is received in the outer layer.
- the elements determine the possible bending radius of the arm.
- the outer layer of the arm may consist of a flexible hose.
- the hose may for example be formed of PVC or other suitable plastic.
- other embodiments of the inner and outer layer of the arm are also possible.
- the power plug may additionally be provided with an overvoltage protection. This prevents any overvoltage caused by a lightning strike in the network from damaging electrical devices connected to the power plug.

In this case, not all of the current required by the load flows through the arm and across the switch, only the current to drive the switch contact. This makes it possible to dimension the arm and the switch correspondingly smaller and thus to make more appealing.
- a surge relay also called current surge switch
- a push button instead of the switch
- the mains voltage is applied to the button, so that the arm and button must be insulated.
- the surge relay is bistable (ie, the two switching states are stored purely mechanically) and unipolar (ie with the same pulse is switched back and forth between the two switching states).
- a control of the switching contact via a low-voltage unit can take place.
- a small control voltage for example 3 V
- the actuation of the switching contact takes place purely mechanically via a ram shaft (for example a fiberglass core) running in the flexible arm.
- a ram shaft for example a fiberglass core
- the switching contact is bistable (i.e., the two switching states are stored purely mechanically).
- the switch can also have a control LED.
- the control LED indicates whether a mains voltage is applied to the power plug or whether the power plug is disconnected from the mains. For example, lighting up the LED may indicate that a mains voltage is applied to the power plug, while not lighting the LED may indicate that the power plug is disconnected from the mains.
- a two-color LED may be used whose color indicates the switching state.
- the switch may be, for example, a push button switch, a push button switch or a rotary switch. However, the use of another suitable type of switch is also possible.

Abstract
Description
Die Erfindung betrifft einen schaltbaren Stromstecker, insbesondere eine aus schaltbarem Stromstecker und einem flexiblen Arm zusammengesetzte Vorrichtung.The invention relates to a switchable power connector, in particular a composed of switchable power connector and a flexible arm device.
Eine schaltbare Steckdose besteht im Wesentlichen aus einer Steckdose und einem mit der Steckdose verbundenem Schalter. Die Steckdose kann hierbei beispielsweise in eine Wand eingelassen sein, oder es kann sich um eine sekundäre Steckdose handeln, die in eine in einer Wand eingelassene Steckdose eingesteckt wird.A switchable socket essentially consists of a socket and a switch connected to the socket. The socket can be embedded in a wall, for example, or it may be a secondary outlet, which is plugged into a recessed in a wall outlet.
Schaltbare Steckdosen bzw. Steckdosenleisten dienen in der Regel dazu, elektrische Vorrichtungen vom Stromnetz trennen zu können. Viele elektrische Vorrichtungen verbrauchen auch in ausgeschaltetem Zustand Strom, falls sich die Vorrichtung in einem Standby Zustand befindet. Durch Verwendung einer schaltbaren Steckdose kann so ein Stromverbrauch einer Vorrichtung in ausgeschaltetem Zustand verhindert werden.Switchable sockets or power strips are usually used to disconnect electrical devices from the mains. Many electrical devices consume power even when turned off when the device is in a standby state. By using a switchable socket so power consumption of a device can be prevented in the off state.
Der Schalter kann mit der Steckdose zum einen mittels einem Kabel verbunden sein, wobei es sich bei dem Kabel um ein herkömmliches Stromkabel handelt, das sich zur Verlegung am Boden eignet. Das Kabel weist zumeist eine relativ kurze Länge auf, so dass wenn sich die Steckdose z.B. hinter Möbeln befindet der Schalter schwer zugänglich ist.The switch can be connected to the socket by means of a cable, the cable being a conventional power cable suitable for laying on the ground. The cable usually has a relatively short length, so that when the socket is plugged in e.g. behind furniture is the switch is difficult to access.
Es kann sich zum anderen beispielsweise um eine fernbedienbare Steckdose handeln, welche eine Sendeeinheit und eine in der Steckdose angeordnete Empfangseinheit enthält. Die fernbedienbare Steckdose weist hierbei eine Reihe von Nachteilen auf. Die Notwendigkeit des Vorsehens einer Sende- und Empfangseinheit führt zu einer erhöhten Komplexität und einer daraus resultierenden Fehleranfälligkeit im Vergleich zu einem kabelgebundenem System. Des Weiteren ist die Fernbedienung in der Regel batteriebetrieben, d.h. es besteht ein Bedarf zum Austausch der Batterien nach Ablauf deren Lebensdauer. Weiterhin sind die Abmessungen einer Fernbedienung im Vergleich zu einem kabelgebundenem Schalter zumeist groß und es besteht die Notwendigkeit der Aufbewahrung der Fernbedienung.On the other hand, it may, for example, be a remotely operable socket which contains a transmitting unit and a receiving unit arranged in the socket. The remote-controlled socket has a number of disadvantages. The necessity of providing a transmitting and receiving unit leads to an increased complexity and a consequent error-proneness compared to a wired system. Furthermore, the remote control is usually battery operated, ie there is a need to replace the Batteries after their lifetime. Furthermore, the dimensions of a remote control compared to a wired switch are usually large and there is a need to store the remote control.
Aufgabe der vorliegenden Erfindung ist es, einen schaltbaren Stromstecker vorzusehen, welcher einen einfachen Aufbau aufweist und eine leichte Zugänglichkeit des Schalters unabhängig von der Position des Stromsteckers gewährleistet.Object of the present invention is to provide a switchable power plug, which has a simple structure and ensures easy accessibility of the switch, regardless of the position of the power plug.
Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruchs gelöst.This object is solved by the features of the independent claim.
Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den abhängigen Ansprüchen wiedergegeben.Advantageous developments of the present invention are given in the dependent claims.
Entsprechend einer bevorzugten Ausführungsform sieht die vorliegende Erfindung einen schaltbaren Stromstecker vor, aufweisend: einen Schaltkontakt, welcher durch einen Schalter betätigbar ist, einen an dem Stromstecker angebrachten Arm, an dessen Ende der Schalter angeordnet ist, dadurch gekennzeichnet, dass der Arm eine Steifigkeit aufweist, die es ermöglicht, dass der Arm unabhängig von seiner Ausrichtung eine beliebige Form beibehält.According to a preferred embodiment, the present invention provides a switchable power plug, comprising: a switch contact, which is actuated by a switch, an arm attached to the power plug, at the end of which the switch is arranged, characterized in that the arm has a rigidity, which allows the arm to maintain any shape regardless of its orientation.
Der an dem Stromstecker angebrachte flexible Arm kann dabei unterschiedliche Längen aufweisen. Die Länge des Arms liegt bevorzugterweise in einem Bereich von 30cm bis 150cm, insbesondere können die Abmessungen des Arms beispielsweise 30cm, 60cm, 90cm, 120cm oder 150cm betragen.The attached to the power plug flexible arm can have different lengths. The length of the arm is preferably in a range of 30cm to 150cm, in particular, the dimensions of the arm may be, for example, 30cm, 60cm, 90cm, 120cm or 150cm.
Der Arm weist entsprechend einer bevorzugten Ausführungsform einen zylinderförmigen Querschnitt auf. Eine andere Form des Querschnitts ist jedoch ebenfalls möglich. Der Arm besteht hierbei aus einer inneren Schicht und einer äußeren Schicht. Die innere Schicht des Arms weist eine höhere Steifigkeit als die äußere Schicht des Arms auf. Die innere Schicht besteht aus einem Material einer vorgegebenen Steifigkeit, welches in eine beliebige Form gebogen werden kann und diese Form unabhängig von seiner Ausrichtung beibehält. Das Material der inneren Schicht kann ein leitendes Material wie z.B. ein Metalldraht sein, welcher den am Ende des Arms angeordneten Schalter mit dem Stromkreis verbindet. Alternativ kann die innere Schicht aus einem biegbaren Material gebildet sein, wobei zusätzlich ein stromführender Draht angeordnet ist, welcher wie vorstehend beschreiben den am Ende des Arms angeordneten Schalter mit dem Stromkreis verbindet.The arm has, according to a preferred embodiment, a cylindrical cross-section. However, another shape of the cross section is also possible. The arm here consists of an inner layer and an outer layer. The inner layer of the arm has a higher rigidity than the outer layer of the arm. The inner layer consists of a material of a given stiffness, which can be bent into any shape and maintains this shape regardless of its orientation. The material of the inner layer may be a conductive material, such as a metal wire, which connects the switch disposed at the end of the arm to the circuit. Alternatively, the inner layer may be formed of a bendable material, wherein additionally a current carrying wire is arranged, which, like describe above the switch arranged at the end of the arm connects to the circuit.
Die äußere Schicht des Arms besteht entsprechend einer bevorzugten Ausführungsform aus einer Vielzahl voneinander beabstandeter Elemente, wobei die innere Schicht in der äußeren Schicht aufgenommen ist. Die Elemente bestimmen hierbei den möglichen Biegeradius des Arms. Entsprechend einer weiteren Ausführungsform kann die äußere Schicht des Arms aus einem flexiblen Schlauch bestehen. Der Schlauch kann beispielsweise aus PVC oder einem anderen geeigneten Kunststoff gebildet sein. Andere Ausgestaltungen der inneren sowie äußeren Schicht des Arms sind jedoch ebenfalls möglich.The outer layer of the arm according to a preferred embodiment consists of a plurality of spaced-apart elements, wherein the inner layer is received in the outer layer. The elements determine the possible bending radius of the arm. According to a further embodiment, the outer layer of the arm may consist of a flexible hose. The hose may for example be formed of PVC or other suitable plastic. However, other embodiments of the inner and outer layer of the arm are also possible.
Der Stromstecker kann zusätzlich mit einem Überspannungsschutz versehen sein. Dieser verhindert, dass es bei einer durch einen Blitzschlag im Netz verursachten Überspannung zu Beschädigungen von an dem Stromstecker angeschlossenen elektrischen Vorrichtungen kommt.The power plug may additionally be provided with an overvoltage protection. This prevents any overvoltage caused by a lightning strike in the network from damaging electrical devices connected to the power plug.
In einer Ausführungsform der Erfindung wird der Stromkreis über den Schalter geschlossen, d.h. der gesamte vom Verbraucher benötigte Strom fließt über den Schalter des Stromsteckers. In diesem Fall muss der Schalter ausreichend dimensioniert sein, um auch für den Anschluss eines oder mehrerer starker Verbraucher geeignet zu sein. Auch der flexible Arm des erfindungsgemäßen Stromsteckers muss ausreichend dimensioniert sein. Bei den üblicherweise im Haushalt verwendeten Sicherungen kann die Stromstärke über den Schalter bis zu 16 A betragen.In one embodiment of the invention, the circuit is closed via the switch, i. All the electricity required by the consumer flows through the switch of the power plug. In this case, the switch must be sufficiently dimensioned to be suitable for the connection of one or more strong consumers. Also, the flexible arm of the power plug according to the invention must be sufficiently dimensioned. With the fuses usually used in the household, the current through the switch can be up to 16A.
In einer weiteren Ausführungsform befindet sich der Schaltkontakt im Steckerteil des Stromsteckers und wird durch die Betätigung des Schalters am Arm geschlossen bzw. geöffnet. In diesem Fall fließt nicht der gesamte vom Verbraucher benötigte Strom durch den Arm und über den Schalter, sondern nur der Strom zur Ansteuerung des Schaltkontakts. Dadurch ist es möglich, den Arm und den Schalter entsprechend geringer zu dimensionieren und somit auch ansprechender zu gestalten.In a further embodiment, the switching contact is in the plug part of the power plug and is closed or opened by the operation of the switch on the arm. In this case, not all of the current required by the load flows through the arm and across the switch, only the current to drive the switch contact. This makes it possible to dimension the arm and the switch correspondingly smaller and thus to make more appealing.
Beispielsweise kann ein Stromstoßrelais (auch Stromstroßschalter genannt) verwendet werden, das über einen Taster (anstelle des Schalters) am Ende des flexiblen Arms angesteuert wird. Auch in diesem Fall liegt am Taster die Netzspannung an, sodass Arm und Taster schutzisoliert sein müssen. Jedoch fließt im eingeschalteten Zustand nicht mehr der gesamte vom Verbraucher benötigte Strom durch den Arm und über den Taster. Vorzugsweise ist das Stromstoßrelais bistabil (d.h. die beiden Schaltzustände werden rein mechanisch gespeichert) und unipolar (d.h. mit dem gleichen Impuls wird zwischen den beiden Schaltzuständen hin- und hergeschaltet).For example, a surge relay (also called current surge switch) can be used, which is controlled by a push button (instead of the switch) at the end of the flexible arm. In this case too, the mains voltage is applied to the button, so that the arm and button must be insulated. However, in the switched-on state, the entire current required by the load no longer flows through the arm and via the push-button. Preferably, the surge relay is bistable (ie, the two switching states are stored purely mechanically) and unipolar (ie with the same pulse is switched back and forth between the two switching states).
Alternativ kann auch eine Ansteuerung des Schaltkontakts über eine Niedervolteinheit erfolgen. In diesem Fall liegt am Taster oder Schalter nur mehr eine geringe Steuerspannung (z.B. 3 V) an.Alternatively, a control of the switching contact via a low-voltage unit can take place. In this case, only a small control voltage (for example 3 V) is present at the pushbutton or switch.
In einer weiteren Ausführungsform erfolgt die Betätigung des Schaltkontakts rein mechanisch über eine im flexiblen Arm verlaufende Stößelwelle (z.B. eine Fiberglasseele). In diesem Fall fließt gar kein Strom mehr durch den Arm und über den Taster oder Schalter. Dadurch sind auch keine elektrischen Isolationsmaßnahmen erforderlich. Vorzugsweise ist der Schaltkontakt bistabil (d.h. die beiden Schaltzustände werden rein mechanisch gespeichert).In a further embodiment, the actuation of the switching contact takes place purely mechanically via a ram shaft (for example a fiberglass core) running in the flexible arm. In this case, no current flows through the arm and the push button or switch. As a result, no electrical insulation measures are required. Preferably, the switching contact is bistable (i.e., the two switching states are stored purely mechanically).
Der Schalter kann zudem eine Kontroll-LED aufweisen. Die Kontroll-LED zeigt an, ob an dem Stromstecker eine Netzspannung angelegt ist, oder ob der Stromstecker vom Netz getrennt ist. Ein Aufleuchten der LED kann beispielsweise anzeigen, dass an dem Stromstecker eine Netzspannung angelegt ist, während ein Nicht-Leuchten der LED anzeigen kann, dass der Stromstecker vom Netz getrennt ist. Alternativ kann eine zweifarbige LED verwendet werden, deren Farbe den Schaltzustand anzeigt.The switch can also have a control LED. The control LED indicates whether a mains voltage is applied to the power plug or whether the power plug is disconnected from the mains. For example, lighting up the LED may indicate that a mains voltage is applied to the power plug, while not lighting the LED may indicate that the power plug is disconnected from the mains. Alternatively, a two-color LED may be used whose color indicates the switching state.
Der Schalter kann beispielsweise ein Druckknopfschalter, ein Drucktastenschalter oder ein Drehschalter sein. Die Verwendung eines anderen geeigneten Typs von Schalter ist jedoch ebenfalls möglich.The switch may be, for example, a push button switch, a push button switch or a rotary switch. However, the use of another suitable type of switch is also possible.
