Description

Die Erfindung bezieht sich auf eine Antennensteckdose, insbesondere zur Anbringung an Gebäudewänden, mit einer ersten Koaxial-Steckbuchse für eine Entnahme von TV-Signalen, mit einem Bandsperrfilter für Hörrundfunk-Signale, dessen Ausgang mit der ersten Koaxial-Steckbuchse verbunden ist, mit einer zweiten Koaxial-Steckbuchse für eine Entnahme von Hörrundfunk-Signalen, mit einem Bandpaßfilter für Hörrundfunk-Signale, dessen Ausgang mit der zweiten Koaxial-Steckbuchse verbunden ist, mit einem ersten Anschluß für ein Koaxialkabel zur Antennensignalzuführung, mit einem zweiten Anschluß für ein Koaxialkabel zur Antennensignalweiterleitung und mit einem Richtungskoppler in Form eines Leitungskopplers oder eines Übertragerkopplers, dessen Durchgangsleitungseingang mit den ersten Anschluß verbunden ist.The invention relates to an antenna socket, in particular for attachment to building walls, with a first coaxial socket for extracting TV signals, with a bandstop filter for radio broadcast signals, the output of which is connected to the first coaxial socket, with a second Coaxial socket for taking radio broadcast signals, with a bandpass filter for radio signals, the output of which is connected to the second coaxial socket, with a first connection for a coaxial cable for antenna signal supply, with a second connection for a coaxial cable for antenna signal transmission and with a directional coupler in the form of a line coupler or a transformer coupler, the feed-through line input of which is connected to the first connection.

Die konstruktive Ausgestaltung einer derartigen Antennensteckdose ist aus der DE-AS 27 33 200, aus der DE-PS 27 33 220 und aus dem Siemens Prospekt "Neue Antennensteckdosen - die Summe Ihrer und unserer Erfahrung", Bestell-Nr. N285/5072 zu entnehmen. Letzterer zeigt weiterhin, daß die Antennensteckdosen einen Richtungskoppler und Filter enthalten.The design of such an antenna socket is from DE-AS 27 33 200, from DE-PS 27 33 220 and from the Siemens brochure "New antenna sockets - the sum of your and our experience", order no. N285 / 5072. The latter further shows that the antenna sockets contain a directional coupler and filter.

Nach einem älteren Vorschlag (P 31 01 288.4) wird eine Antennensteckdose mit einem dritten Anschluß versehen, der einer Einspeisung von Rückkanalsignalen für eine Zentrale dient. Derartige Signale sind beim Fernsehen, beim Hörrundfunk, bei der Text- und Bildverteilung, bei Warndiensten, bei Teilnehmersignalea, beim Fernmessen, bei der Überwachung, bei lokalen Programmen, beim Auftragsdienst, beim Informationsdienst, beim Bibliotheksdienst, bei interaktiven Diensten, bei der Bestandsführung und bei der Datenfernverarbeitung von Interesse.According to an older proposal (P 31 01 288.4) an antenna socket is provided with a third connection, which is used to feed back channel signals for a control center. Such signals are used in television, radio broadcasting, text and image distribution Warning services of interest to subscriber signals, telemetry, surveillance, local programs, order service, information service, library service, interactive services, inventory management and remote data processing.

Der Erfindung liegt die Aufgabe zugrunde, einen derartigen dritten Anschluß unter Verwendung herkömmlicher Antennensteckdosen zu realisieren.The invention has for its object to realize such a third connection using conventional antenna sockets.

Ausgehend von einer Durchgangssteckdose der einleitend geschilderten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß der Durchgangsleitungsausgang des Richtungskopplers mit den Eingängen des Bandpaßfilters und des Bandsperrfilters verbunden ist und daß der Ausgang der Koppelschleife des Richtungskopplers mit dem zweiten Anschluß verbunden ist.Starting from a through socket of the type described in the introduction, this object is achieved according to the invention in that the through line output of the directional coupler is connected to the inputs of the bandpass filter and the bandstop filter and that the output of the coupling loop of the directional coupler is connected to the second connection.

Die erfindungsgemäß beschaltete Dose stellt eine Stichleitungsdose dar, über deren "abgehende" Koaxialleitung Zusatzsignale eingespeist oder entnommen werden können. Beispielsweise kommen trägerfrequente Digitalsignale zur Teilnehmeradressierung in Frage. Die "abgehende" Koaxialleitung führt dann zu einem Modem. Die Frequenz der eingespeisten Signale kann unterhalb 40 MHz liegen; die entnommenen Signale können das Frequenzband von 40 bis 860 MHz einnehmen.The socket connected according to the invention represents a stub socket, via whose “outgoing” coaxial line additional signals can be fed in or taken out. For example, carrier-frequency digital signals can be used for addressing subscribers. The "outgoing" coaxial line then leads to a modem. The frequency of the signals fed in can be below 40 MHz; the extracted signals can occupy the frequency band from 40 to 860 MHz.

Die erfindungsgemäße Antennensteckdose kann anstelle eines Richtungskopplers auch eine entsprechende Frequenzweichenschaltung enthalten.The antenna socket according to the invention can also contain a corresponding crossover circuit instead of a directional coupler.

Außerdem ist es vorteilhaft, wenn an die Stelle des Richtungskopplers die Kombination von Richtungskoppler und frequenzselektiven Mitteln für Zusatzsignale tritt.It is also advantageous if the combination of directional coupler and frequency-selective means for additional signals takes the place of the directional coupler.

Anhand eines Ausführungsbeispiels wird die Erfindung nachstehend näher erläutert.

  • Fig. 1 zeigt eine Draufsicht einer bekannten Durchgangsdose und
  • Fig. 2 zeigt die Beschaltung der Dose nach Fig. 1 als Durchgangsdose nach dem Stand der Technik.
  • Fig. 3 zeigt die Beschaltung der Dose nach Fig. 1 als Stichleitungsdose nach dem Stand der Technik.
  • Fig. 4 zeigt die erfindungsgemäße Beschaltung der Dose nach Fig. 1 mit einem Leitungskoppler und
  • Fig. 5 zeigt die erfindungsgemäße Beschaltung der Dose nach Fig. 1 mit einem Ubertragerkoppler.
  • Fig. 1 zeigt die aus der eingangs genannten DE-PS 27 33 220 bekannte Antennensteckdose. Diese enthält einen ersten Anschluß 1 für ein erstes Koaxialkabel, eine erste Koaxial-Steckbuchse 2, eine zweite Koaxial-Steckbuchse 3 und einen zweiten Anschluß 4 für ein zweites Koaxialkabel. Die beiden Koaxialkabel befinden sich in der Darstellung unter einer Klappschelle. Die Hinweislinien von den Bezugszeichen 1 und 4 weisen auf Stellen, wo sich die Koaxialkabel unter der Klappschelle befinden.
  • Fig. 2 zeigt die bekannte Beschaltung der Dose nach Fig. 1 als Durchgangsdose. Diese enthält einen Richtungskoppler 5 für 40 bis 860 MHz, ein Bandsperrfilter 6 für Hörrundfunk-Signale und ein Bandpaßfilter 7 für Hörrundfunk-Signale. Die Antennensignale durchlaufen die Dose unverändert vom Anschluß 1 zum Anschluß 4. An der Koaxial-Steckbuchse 2 liegen TV-Signale ohne Hörrundfunk-Signale und an der Koaxial-Steckbuchse 3 nur Hörrundfunk-Signale an.
  • Fig. 3 zeigt die Beschaltung der Dose nach Fig. 1 als Stichleitungsdose. Im Gegensatz zur Schaltung nach Fig. 2 erübrigt sich der Richtungskoppler 5 und ein Koaxialkabel zur Antennensignalweiterleitung. Die Eingänge des Bandsperrfilters 6 und des Bandpaßfilters 7 sind unmittelbar mit dem Koaxialkabel-Anschluß 1 verbunden.
  • Fig. 4 zeigt die erfindungsgemäße Beschaltung der Dose 1. Im Gegensatz zur Schaltung nach Fig. 3 ist zwischen den Koaxialkabel-Anschluß 1 und die Eingänge des Bandsperrfilters 6 und des Bandpaßfilters 7 ein Richtungskoppler 5' für 5 bis 860 MHz zwischengeschaltet. Der Ausgang der Auskoppelschleife des Richtungskopplers 5' ist mit dem Anschluß 4 verbunden.
The invention is explained in more detail below using an exemplary embodiment.

  • Fig. 2 shows the wiring of the box of Fig. 1 as a through box according to the prior art.
  • Fig. 3 shows the wiring of the box of FIG. 1 as a branch line box according to the prior art.
  • Fig. 4 shows the circuit according to the invention of the box of FIG. 1 with a line coupler and
  • FIG. 5 shows the circuitry according to the invention for the socket according to FIG. 1 with a transmitter coupler.
  • Fig. 1 shows the antenna socket known from the aforementioned DE-PS 27 33 220. This contains a first connection 1 for a first coaxial cable, a first coaxial socket 2, a second coaxial socket 3 and a second connection 4 for a second coaxial cable. The two coaxial cables are shown under a hinged clamp. The lines of reference from the reference numerals 1 and 4 indicate where the coaxial cables are located under the clip.
  • Fig. 2 shows the known wiring of the box of Fig. 1 as a through box.

The antenna signals pass through the socket unchanged from connection 1 to connection 4. TV signals without radio broadcast signals are located at the coaxial socket 2 and at the coaxial socket 3 only radio broadcast signals.
  • Fig. 3 shows the wiring of the box according to Fig. 1 as a branch line box. In contrast to the circuit according to FIG. 2, the directional coupler 5 and a coaxial cable for antenna signal transmission are unnecessary. The inputs of the bandstop filter 6 and the bandpass filter 7 are connected directly to the coaxial cable connection 1.
  • Fig. 4 shows the wiring of the socket 1 according to the invention. In contrast to the circuit according to Fig. 3, a directional coupler 5 'for 5 to 860 MHz is interposed between the coaxial cable connection 1 and the inputs of the bandstop filter 6 and the bandpass filter 7. The output of the coupling loop of the directional coupler 5 'is connected to the terminal 4.

Der Anschluß 4 bietet jetzt eine Anschlußmöglichkeit für Geräte zusätzlicher Dienste, die sowohl in Rückrichtung Signale abgeben als ggf. auch aus der Anlagenverteilrichtung Zusatzsignale, wie beispielsweise trägerfrequente Digitalsignale zur Teilnehmeradressierung aufnehmen können.The connection 4 now offers a connection option for devices for additional services which can emit signals both in the reverse direction and, if appropriate, also receive additional signals from the system distribution direction, such as, for example, carrier-frequency digital signals for subscriber addressing.

Vom Anschluß 4 kann eine Verbindung zu einem Modem hergestellt werden, das die Trägerfrequenz-Zusatzsignale der Abwärtsrichtung, die beispielsweise im Frequenzbereich 40 bis 860 MHz übertragen werden können, aufnimmt und trägerfrequente Zusatzrücksignale unterhalb 40 MHz in die Anlage einspeist. Der breitbandige Richtungskoppler 5' bietet den Vorteil der gegenseitigen Entkopplung von an die Koaxial-Steckbuchsen 2 und 3 angeschlossenen Fernseh (TV)- bzw. Hörrundfunkgeräten und dem Gerät für Zusatzdienste.A connection can be made from port 4 to a modem which receives the carrier frequency additional signals in the downward direction, which can be transmitted, for example, in the frequency range 40 to 860 MHz, and feeds carrier-frequency additional return signals below 40 MHz into the system. The broadband directional coupler 5 'offers the advantage of mutual decoupling of television (TV) or radio broadcasting devices connected to the coaxial sockets 2 and 3 and the device for additional services.

Fig. 5 zeigt eine der Anordnung nach Fig. 4 entsprechende Anordnung mit einem Übertragerkoppler 5".FIG. 5 shows an arrangement corresponding to the arrangement according to FIG. 4 with a transformer coupler 5 ".

Anstelle des Richtungskopplers 5' kann je nach Frequenzbelegung auch eine entsprechende Frequenzweichenschaltung treten.Instead of the directional coupler 5 ', a corresponding crossover circuit can also be used, depending on the frequency assignment.
