Description

lie Erfindung betrifft ein Netztrenngerät, das zur Verwendung im Zusammenhang mit Fernsprechanlagen verwendet wird.lie invention relates to a power disconnector that is used for Use in conjunction with telephone systems.

Die Erfahrung zeigt, daß es schwierig, wenn nicht gar unmöglich ia. ein Telefongespräch zu führen, wenn zur gleichen Zeit ein im gleichen Raum betriebenes elektro-akustisches Unterhaltungsgerät betrieben wird oder wenn der Telefonierende daneben noch ein anderes elektrisches Gerät zu beobachten hat, das bei Erreichen eines bestimmten Betriebszustandes abgeschaltet werden muß (Kochplatte Bügeleisen u. dgl.).Experience shows that it is difficult, if not impossible impossible ia. make a phone call when to an electro-acoustic entertainment device operated in the same room is operated at the same time or if the person making the call has to observe another electrical device next to it, which is at Must be switched off when a certain operating state is reached (hotplate, iron, etc.).

Der Erfindung liegt die Aufgabe zugrunde, ein Netztrenngerät zu schaffen, das so an das Fernmeldenetz gekoppelt ist, daß bei einem ankommenden Ruf entweder das störende akustische Gerät vom Netz getrennt oder .ber dessen nachgeschaltete Lautsprecher abgeschaltet werden. Die letztgenannte Forderung ist insbesondere dann von Bedeutung, wenn in bestimmten Räumen lediglich Lautsprecher installiert sind, die von einer zentralen, in einem anderen Raum befindlichen elektro-akustischen Anlage gespeist werden. The invention is based on the object of creating a network isolating device that can be connected to the telecommunications network is coupled that with an incoming call either the disturbing acoustic device from the network be switched off separately or via its downstream loudspeaker. The latter requirement is particularly important if only loudspeakers are installed in certain rooms that are fed by a central electro-acoustic system located in another room.

Erfindungsgemäß wird zur Lösung dieser Aufgabe ein Netztrenngerät mit einer galvanischen, induktiven oder kapazitiven Ankopplung in der Weise, daß durch das Anrufsignal ein gerade in Betrieb befindliches akustisches oder sonstiges elektrisches Gerät über eineAccording to the invention to solve this problem, a power disconnect device with a galvanic, inductive or capacitive coupling in such a way that the call signal produces an acoustic signal that is currently in operation or other electrical device via a

Die Wiedereinschaltung des Gerätes bzw. derThe restart of the device or the

Lautsprecher des Gerätes erfolgt in Weiterbildung der Erfindung über eine Handschaltung, sie kann jedoch auch automatisch durch das Netztrenngerät erfolgen.The loudspeaker of the device is carried out in the development of the Invention via a manual switch, but it can also be done automatically by the power disconnector.

Das erfindungsgemäde Netztrenngerät wird zweckmäßig mit den Femsprechleitungsklemmen innerhalb einer Anschlußdose verbunden, falls eine galvanische Ankopplung an das Netz gewünscht wird. Statt dessen kann das erfindungsgemäße Netztrenngerät unmittelbar neben dem zu überwachenden Fernsprechapparat angeordnet werden, wobei dann die Rufankopplung kapazitiv oder induktiv erfolgt
Die Erfindung wird im folgenden unter Bezugnahme auf das in der Zeichnung dargestellte Ausführungsbeispiel der Schaltung eines erfindungsgemäßen Netztrenngerätes näher erläutert. Gemäß diesem Blockschaltbild ist in die Fernsprech-Anschlußleitung 1 die Verbindungsdose 1 geschaltet, an der der Fernsprechap-
The mains disconnection device according to the invention is expediently connected to the telephone line terminals within a junction box if a galvanic coupling to the mains is desired. Instead, the power disconnection device according to the invention can be arranged directly next to the telephone set to be monitored, the call coupling then taking place capacitively or inductively
The invention is explained in more detail below with reference to the exemplary embodiment of the circuit of a mains isolating device according to the invention shown in the drawing. According to this block diagram, the junction box 1 is connected in the telephone connection line 1 to which the telephone
