Abstract

Die Vorrichtung dient zum elektrischen Anschließen eines Modems 1 bei der leitungsgebundenen Datenübertragung an ein Stromnetz, wobei die Verbindungsleitung 4 des Modems 1 einen Netzstecker 5 aufweist. Der Netzstecker 5 ist mit einem Breitband-Netzfilter 3 zum Ausfiltern von Störimpulsen durch induktive oder kapazitive Verbraucher und von in das Netz zurückgespeisten hochfrequenten Strömen versehen.The device is used for the electrical connection of a modem 1 in the case of wired data transmission to a power grid, the connecting line 4 of the modem 1 having a power plug 5. The mains plug 5 is provided with a broadband mains filter 3 for filtering out interference pulses by inductive or capacitive loads and high-frequency currents fed back into the mains.

Description

Die Erfindung betrifft eine Vorrichtung zum elektrischen Anschließen eines Modems bei der leitungsgebundenen Datenübertragung an ein Stromnetz, wobei die Verbindungsleitung des Modems einen Netz­ stecker aufweist.The invention relates to a device for electrical connection a modem in the wired data transmission to Power network, the connecting line of the modem is a network has plug.

Bei der leitungsgebundenen Datenübertragung werden Datensignale neben der üblichen 50 Hz-Spannung auf Stromleitungen aufmoduliert. Hierbei übersteigen die Pegel der Signalspannungen den 1 V-Wert nicht und die Frequenzen liegen, abhängig von den benutzten Modulations­ verfahren, im Bereich von 1,5 bis 30 MHz. Die Verbindung zwischen Geräten, die in einem vermaschten Stromnetz angeschlossen sind, erfolgt nach den Prinzipien eines Datennetzes mit einem Bus als Medium.In the case of wired data transmission, data signals modulated on power lines in addition to the usual 50 Hz voltage. The levels of the signal voltages do not exceed the 1 V value and the frequencies are depending on the modulation used process, in the range of 1.5 to 30 MHz. The connection between Devices that are connected in a meshed power network takes place according to the principles of a data network with a bus as Medium.

Der Anschluß des Modems erfolgt normalerweise über übliche Netz­ stecker, wie sie an Haushaltsgeräten vorhanden sind. Die langen, ungeschirmten und geradlinig verlaufenden Stromleitungen wirken für hochfrequente Signale wie Antennen. Im Spektrum des Signals sind alle Radiosender hörbar. Diese Störungen aus der Sicht der leitungs­ gebundenen Datenübertragung, können nicht umgangen werden. Eine andere Störquelle sind Haushaltsgeräte (induktive oder kapazitive Verbraucher), zum Beispiel alle Geräte mit Motoren, die hochfrequente Impulse ins Netz zurückspeisen.The modem is usually connected via a normal network plugs as they are on household appliances. The lengths, unshielded and rectilinear power lines work for high-frequency signals such as antennas. Everyone is in the spectrum of the signal Radio station audible. This interference from the point of view of the management bound data transmission, can not be bypassed. A other sources of interference are household appliances (inductive or capacitive Consumers), for example all devices with motors that are high-frequency Feed impulses back into the network.

Der Erfindung liegt die Aufgabe zugrunde, diese Störimpulse durch eine einfache Einrichtung zu beseitigen.The invention has for its object this interference by a easy to eliminate setup.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Netzstecker mit einem Breitband-Netzfilter zum Ausfiltern von Störimpulsen durch induktive oder kapazitive Verbraucher und von in das Netz zurückgespeisten hochfrequenten Strömen versehen ist.This object is achieved according to the invention in that the Power plug with a broadband line filter to filter out  Interference from inductive or capacitive loads and from the network is fed back with high-frequency currents.

Die Erfindung bringt den Vorteil, dass der Nutzer der Einrichtung keine zusätzlichen Geräte oder Installationen braucht, um diese Störimpulse auszuschließen. Er braucht lediglich den Netzstecker an das Stromnetz anzuschließen bzw. in die entsprechende Steckdose einzustecken.The invention has the advantage that the user of the device no additional equipment or installations needed to do this Exclude interference pulses. He only needs the power plug connect the power supply or into the appropriate socket insert.

Die Erfindung wird in der nachfolgenden Beschreibung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung ist eine herkömmliche Steckdose 2 dargestellt, in die ein Netzstecker 5, der über eine Verbindungsleitung 4 mit dem Modem 1 verbunden ist, eingesteckt wird. In den Netzstecker 5 ist ein Breitband-Netzfilter 3 integriert, der die HF-Signale ins Stromnetz lässt, wobei der Filter vermeidet, dass andere induktive oder kapazitive Verbraucher das Datenübertragungs-Signal stören.The invention is explained in more detail in the following description with reference to an embodiment shown in the drawing. In the drawing, a conventional socket 2 is shown, into which a power plug 5 , which is connected to the modem 1 via a connecting line 4 , is inserted. A broadband network filter 3 is integrated in the mains plug 5 , which lets the HF signals into the power network, the filter avoiding that other inductive or capacitive consumers interfere with the data transmission signal.
