Description

Die Erfindung betrifft ein Signalkabel, wie als Verstärkerkabel, mit zwei nebeneinander verlaufenden isolierten Leitern mit Anschlußelementen.The invention relates to a signal cable, such as an amplifier cable, with two insulated conductors running alongside one another with connection elements.

Die Erfindung bezieht sich insbesondere auf ein Signalkabel, wie sie bei der Übertragung von Musiksignalen zwischen Komponenten einer Musikanlage auftreten.Neben solchen Phonokabeln bezieht sich die Erfindung auch auf Kabel zur Übertragung digitaler Signale, beispielsweise in der Datenkommunikation.The invention relates in particular to a signal cable such as occurs in the transmission of music signals between components of a music system. In addition to such phono cables, the invention also relates to cables for the transmission of digital signals, for example in data communication.

Üblicherweise werden beispielsweise als Signalkabel solche mit einer gemeinsamen Abschirmung beider Leiter durch eine diese umgebende Schirmleitung benutzt,die mit einer der Einzel leitern am Anschlußelement elektrisch verbunden ist.Usually, for example, those with a common shielding of both conductors are used as signal cables by a surrounding shielding line which is electrically connected to one of the individual conductors on the connecting element.

Weiterhin wurde schon versucht Koaxialkabel einzusetzen, bei denen also der eine Einzelleiter eine Litze Ist und der andere Einzelleiter ein diese umgebender koaxialer Schirm ist. Schließlich wurde versucht zwei im Querschnitt ringförmige Leitungen koaxial zueinander anzuordnen, um so die Übertragungseigenschaften eines solchen Kabels zu verbessern. Im allgemeinen bedingt aber die Erreichung der Verbesserung hinsichtlich einer Kenngröße eine Verschlechterung hinsichtlich anderer Kenngrößen, so daß im allgemeinen bei den bekannten Kabeln immer gewisse Nachteile in Kauf zu nehmen sind bzw. in Kauf genommen werden, wenn diese als weniger gewichtig bewertet werden.Furthermore, attempts have already been made to use coaxial cables in which one single conductor is a stranded wire and the other single conductor is a coaxial shield surrounding it. Finally, attempts were made to arrange two lines which are ring-shaped in cross-section coaxially with one another in order to improve the transmission properties of such a cable. In general, however, the achievement of the improvement with regard to one parameter causes a deterioration with respect to other parameters, so that in general with the known cables there are always certain disadvantages to be accepted or accepted if these are rated as less important.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Signalkabel in der eingangs genannten Art zu entwickeln, das gegenüber den bekannten Kabeln wesentlich bessere Übertragungseigenschaften aufweist und insbesondere parasitäre magnetische und/oder kapazitive Verkopplungen der beiden Einzelleiter mit hierdurch verbundenen nachteiligen Impulsverzögerungen und hierdurch bedingten Verzerrungen ebenso vermeidet, wie äußere Störungen und deren Einfluß auf die Einzelleiter bzw. die durch diese übertragenen Signale.The invention is therefore based on the object of developing a signal cable of the type mentioned which has significantly better transmission properties than the known cables and in particular also avoids parasitic magnetic and / or capacitive couplings of the two individual conductors, with the associated disadvantageous pulse delays and distortions caused thereby , such as external disturbances and their influence on the individual conductors or the signals transmitted through them.

Erfindungsgemäß wird die genannte Aufgabe dadurch gelöst, daß jeder Leiter von einem gegen ihn und gegeneinander isolierten eigenen koaxialen Einzelschirm umgeben ist und daß die Einzelschirme gegen die Anschlußelemente isoliert sind. Durch die erfindungsgemäße Ausgestaltung wird zunächst eine Abschirmung der parallel verlaufenden Einzelleiter gegen Außenstörungen erreicht,darüberhinaus aber eine gegenseitige Abschirmung der Einzelleiter sowie eine Senkung der Gesamtkapazität des Kabels, wodurch eine Verringerung der gegenseitigen Beeinflussung der signalführenden Einzelleiter erzielt wird. Wesentlichist nicht nur, daß die Einzel leiter jeweils durch Einzelschirme nach außen hin und gegeneinander abgeschirmt sind, sondern darüberhinaus daß die einzelnen Schirme selbst nicht mit den Anschlußelementen und insbesondere auch dadurch auch nicht mit einem Einzelleiter elektrisch verbunden sind, sondern vielmehr in jeder Hinsicht elektrisch isoliert sind. Durch die erfindungsgemäße Ausgestaltung werden einerseits induktive, eine ungestörte Signalübertragung hindernde bzw. einer solchen entgegenstehende Einflüsse vermieden und andererseits praktisch eine Reihenanordnung von Kapazitäten mit der hierdurch bedingten Verringerung der Gesamtkapazität erzielt.According to the invention, the stated object is achieved in that each conductor is surrounded by its own coaxial individual shield that is insulated against it and against one another and that the individual shields are insulated from the connection elements. Due to the configuration according to the invention First a shielding of the parallel single conductors against external interference is achieved, but moreover a mutual shielding of the individual conductors and a reduction in the total capacitance of the cable, thereby reducing the mutual influence of the signal-carrying individual conductors. It is essential not only that the individual conductors are each shielded from one another to the outside and against one another, but moreover that the individual shields themselves are not electrically connected to the connecting elements and in particular also not to a single conductor, but rather are electrically insulated in every respect are. The design according to the invention on the one hand avoids inductive influences which prevent an undisturbed signal transmission or oppose such interference and on the other hand practically achieves a series arrangement of capacitances with the resulting reduction in the total capacitance.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, daß die Leiter und die Einzelschirme gemeinsam von einem isolierten Gesamtschirm umgeben sind, wobei insbesondere auch in ansich bekannter Weise vorgesehen sein kann, daß der Gesamtschirm, nicht aber die Einzelschirme mit einem der Anschlußelemente elektrisch verbunden sind. In weiterer Ausgestaltung ist vorgesehen, daß die Einzelschirme als blanke verzinnte Kupfergewebe ausgebildet sind und/oder daß die Leiter versilbert sind. Grundsätzlich könnte auch der Gesamtschirm als blankes oder verzinntes Kupfergewebe ausgebildet sein, aber gemäß einer bevorzugten Ausgestaltung ist aber vorgesehen, daß der Gesamtschirm als versilbertes Kupfergewebe ausgebildet ist. Ins- , besondere in dem Fall, daß die Einzelleiter eine größere Stärke, beispielsweise im Bereich von einem Querschnitt über 0,5mm2 aufweisen, bestehen diese vorteilhafterweise aus einzeln isolierten Litzen, die vorzugsweise selbst versilbert sind; es kann eine Isolierung, aus Fluorkohlenstoffmaterial, wie (P)TFE, FEP, PFA gewählt werden.According to a preferred embodiment of the invention it is provided that the conductors and the individual shields are jointly surrounded by an insulated overall shield, it being possible in particular in a manner known per se that the overall shield, but not the individual shields, is electrically connected to one of the connection elements. In a further embodiment it is provided that the individual shields are designed as bare tinned copper mesh and / or that the conductors are silver-plated. In principle, the overall screen could also be designed as a bare or tinned copper mesh, but according to a preferred embodiment, it is provided that the overall screen is designed as a silver-plated copper mesh. In particular, in the event that the individual conductors have a greater thickness, for example in the region of a cross section of more than 0.5 mm 2, these advantageously consist of individually insulated strands, which are preferably themselves silver-plated; insulation made of fluorocarbon material such as (P) TFE, FEP, PFA can be selected.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Ansprüchen und aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel des erfindungsgemäßen Kabels unterBezugnahme auf die Zeichnung im einzelnen erläutert ist. Dabei zeigt:

  • Figur 1 eine Seitenansicht einer bevorzugten Ausgestaltung des erfindungsgemäßen Kabels, mit teilweise weggebrochenen Teilen;
  • Figur 2 eine schematische Darstellung der einzelnen nicht isolierenden Elemente des Kabels nach Figur 1;
  • Figur 3 einen Schnitt entlang der Linie III-III der Figur 1; und
  • Figur 4 eine schematische Darstellung des Schnitts der Figur 3.
Further advantages and features of the invention result from the claims and from the following description, in which an embodiment of the cable according to the invention is explained in detail with reference to the drawing. It shows:
  • Figure 1 is a side view of a preferred embodiment of the cable according to the invention, with parts broken away;
  • Figure 2 is a schematic representation of the individual non-insulating elements of the cable of Figure 1;
  • 3 shows a section along the line III-III of Figure 1; and
  • Figure 4 is a schematic representation of the section of Figure 3.

Das erfindungsgemäße Signalkabel 1 weist zwei Einzelleiter 2, 3 auf. Die Leiter 2, 3 sind an ihren Enden mit Anschlußelementen 4 in Form von Steckern verbunden, wobei der Leiter 2 mit einer Steckerbuchse 6 und der Leiter 3 jeweils mit einem gegen die Steckerbuchse 6 isolierten Steckstift 7 elektrisch verbunden ist.The signal cable 1 according to the invention has two individual conductors 2, 3. The conductors 2, 3 are connected at their ends to connecting elements 4 in the form of plugs, the conductor 2 being electrically connected to a plug socket 6 and the conductor 3 being each electrically connected to a plug pin 7 insulated from the socket 6.

Die Einzelleiter 2, 3 können beispielsweise aus versilberten Kupferlitzen bestehen. Wenn die Einzelleiter 2, 3 größere Querschnitte, beispielsweise über 0,5 mm2 aufweisen, so ist es vorteilhaft die Leiter mit einzeln isolierten Litzen auszubilden, wobei die Litzen beispielsweise eine PTFE-Isolierung aufweisen.The individual conductors 2, 3 can consist, for example, of silver-plated copper strands. If the individual conductors 2, 3 have larger cross sections, for example more than 0.5 mm 2 , it is advantageous to design the conductors with individually insulated strands, the strands having, for example, PTFE insulation.

Die Leiter 2, 3 sind jeweils als solche von einem Isoliermantel 8, 9 umgeben. Um die Isolierung 8, 9 herum ist jeweils koaxial zu den Leitern 2, 3 ein Einzelschirm 11, 12 aus elektrisch leitfähigem netzartigen Abschirmgeflecht angeordnet. Jeder Einzelschirm 11, 12 ist wiederum von einem Isoliermantel 13, 14 umgeben. Insofern entspricht der beschriebene Aufbau jeder Einzelleiteranordnung 2, 8 , 11, 13 bzw. 3, 9, 12, 14 ansich einem Koaxialkabel. Während bei einem Koaxialkabel aber sowohl der Innenleiter (hier beispielsweise 3) als auch das Abschirmgeflecht (hier beispielsweise12)und einem Pol eines Steckverbinders verbunden ist, enden erfindungsgemäß die Einzelabschirmungen 11, 12 vor den Steckelementen 4, sind mit diesen nicht verbunden, sondern gegenüber diesen Isoliert.The conductors 2, 3 are each as such surrounded by an insulating jacket 8, 9. A single shield 11, 12 made of electrically conductive, mesh-like shielding braid is arranged around the insulation 8, 9 coaxially with the conductors 2, 3. Each individual screen 11, 12 is in turn surrounded by an insulating jacket 13, 14. In this respect, the structure of each individual conductor arrangement 2, 8, 11, 13 or 3, 9, 12, 14 described corresponds to a coaxial cable. While in a coaxial cable both the inner conductor (here, for example, 3) and the shielding braid (here, for example, 12) and a pole of a connector are connected, according to the invention, the individual shields 11, 12 end in front of the plug-in elements 4, are not connected to them, but rather opposite them Isolated.

Beide Einzelleiteranordnungen 2,8, 11, 13 und 3, 9, 12, 14 sind im dargestellten Ausführungsbeispiel in einem gemeinsamen isolierenden Innenmantel 16 angeordnet, der aus elektrotechnischen Gründen bei der dargestellten Ausführungsform des erfindungsgemäßen Signalkabels 1 ansich nicht erforderlich ist, da jede Einzelleiteranordnung durch die Mäntel 13, 14 isoliert ist, aber auch aus mechanischen Gründen vorzuziehen ist. Der Innenmantel 16 ist wiederum koaxial von einem Gesamtschirm 17 in Form ebenfalls eines leitenden Abschirmgeflechts umgeben. Nach außen schließt sich weiterhin ein Außenisollermantel 18 an, der das gesamte Signalkabel nach außen hin abisoliert. Der Gesamtschirm 17 ist zumindestens mit einem der Anschlußelemen te 4 und dort mit einem der Pole 6 bzw. 7, im dargestellten Ausführungsbeispiel mit der Steckhülse 6 elektrisch verbunden.In the exemplary embodiment shown, both individual conductor arrangements 2, 8, 11, 13 and 3, 9, 12, 14 are arranged in a common insulating inner jacket 16, which is not required for electrical engineering reasons in the illustrated embodiment of the signal cable 1 according to the invention, since each individual conductor arrangement is due to the coats 13, 14 is insulated, but is also preferable for mechanical reasons. The inner jacket 16 is in turn coaxially surrounded by an overall screen 17 in the form of a conductive shielding braid. To the outside there is also an outer jacket 18 which strips the entire signal cable from the outside. The overall screen 17 is at least one of the connecting elements te 4 and there with one of the poles 6 and 7, in the illustrated embodiment with the socket 6 electrically connected.

Das erfindungsgemäße Signalkabel 1 bietet nicht nur eine optimale Abschirmung von Außenstörungen, sondern darüberhinaus insbesondere eine Verringerung der gegenseitigen Beeinflussung der signalführenden Leiter, was bei bekannten Signalkabeln zu Störungen, Verzerrungen etc. führt. Die erfindungsgemäßen Vorteile werden insbesondere dadurch erreicht, daß die Abschirmungen 11, 12 selbst nicht in den elektrischen Leitungsvorgang mit eingeschaltet sind, sondern vielmehr gegenüber den Anschlußelementen isoliert sind und ledigl ich Abschirmaufgaben erfüllen. Neben dem Einsatz im Musikbereich eignet sich das erfindungsgemäße Kabel auch zur Übertragung in der Datenkommunikation, da durch die erfindungsgemäße Ausgestaltungen Laufzeitverzerrungen etc . minimiert werden.The signal cable 1 according to the invention not only offers optimal shielding from external interference, but moreover in particular a reduction in the mutual influence of the signal-carrying conductors, which is the case with known signals leads to interference, distortion, etc. The advantages according to the invention are achieved in particular in that the shields 11, 12 themselves are not switched on in the electrical conduction process, but rather are insulated from the connection elements and only perform shielding tasks. In addition to use in the music field, the cable according to the invention is also suitable for transmission in data communication, since the embodiments according to the invention distort runtime etc. be minimized.
