Description
* 1* 1
Die Erfindung betrifft elektrisches Niederfrequenzkabel mit zumindest zwei elektrischen Leitern aus Kupfer und zumindest einem Isolator.The invention relates to a low-frequency electrical cable with at least two electrical conductors made of copper and at least one insulator.
Derartige Niederfrequenzkabel sind insbesondere aus dem Audio-, Videobereich als Verbindungskabel, Lautsprecherkabel hinlänglich bekannt. Jedoch weisen diese Kabel aufgrund hoher elektrischer Verluste den Nachteil eines erheblichen Leistungsverlustes, beispielsweise in Bezug auf den Klang, auf, der durch die erheblich verbesserte Aufnahme- und Wiedergabequalität heutiger Audio-, Videogeräte besonders deutlich wird.Such low frequency cables are well known, particularly in the audio and video sector, as connecting cables and loudspeaker cables. However, due to high electrical losses, these cables have the disadvantage of a significant loss of performance, for example in terms of sound, which is particularly evident due to the significantly improved recording and playback quality of today's audio and video devices.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, den obengenannten Nachteil zu vermeiden.The present invention is therefore based on the object of avoiding the above-mentioned disadvantage.
Diese Aufgabe wird dadurch gelöst, daß der Isolator aus Teflon besteht. Die niedricge Reiheninduktivität und sehr niedriege Kapazität eines derartigen Niederfrequenzkabels bedingen shr geringe Leitungsverluste.This task is solved by using a Teflon insulator. The low series inductance and very low capacitance of such a low frequency cable result in very low line losses.
Ein optimaler Widerstandswert wird darüberhinaus dadurch bedingt, daß der Isolator ein Teflonschlauch ist, auf dem zwei sechsfach-Massivleiter sich unter einem Winkel von ca. 90° kreuzend angeordnet sind, wobei die sechsfach Massivleiter versilbert sein können.An optimal resistance value is also achieved by the fact that the insulator is a Teflon tube on which two six-fold solid conductors are arranged crossing at an angle of approx. 90°, whereby the six-fold solid conductors can be silver-plated.
Die sich kreuzenden sechsfach-Massivleiter können dabei mit einem Abstand von ca. 2,5 cm auf dem Teflonschlauch angeordnet sein, wobei der Teflonschlauch einen Innendurchmesser von ca. 4 mm und einen Aussendurchmesser von ca. 8 mm aufweist.The crossing six-fold solid conductors can be arranged on the Teflon tube with a distance of approx. 2.5 cm, whereby the Teflon tube has an inner diameter of approx. 4 mm and an outer diameter of approx. 8 mm.
Auch kann ein elektrisches Niederfrequenzkabel derart ausgeführt sein, daß als erster Leiter ein Kupferdraht vorgesehen ist, um den ein Wabenisolator aus Teflon angeordnet ist, der auf seiner Aussenfläche einen Kupferschirm als zweitem Leiter aufweist, der wiederum durch einen Schrumpfschlauch aus Teflon umhüllt ist. Vorteilhafterweise besitzt der Kupferschirm dabei eine Dicke von 0,1 mm. Diese Ausführungsform ist insbesonder zur Verwendung eines Lautsprecherkabels geeignet, daß zwei derartige elektrische Niederfrequenzkabeln aufweist, die mittels Abstandshaltern parallel zueinander verlaufend von jeweils einem Gewebeschlauch umhüllt sind. Dabei ist die Verlustleistung besonders gering, wenn der erste Leiter des ersten Niederfrequenzkabels mit dem zweiten Leiter des zweiten Niederfrequenzkabels elektrisch verbunden ist und der zweite Leiter des ersten Niederfrequenzkabels mit dem ersten Leiter des zweiten Niederfrequenzkabels elektrisch verbunden ist.An electrical low-frequency cable can also be designed in such a way that a copper wire is provided as the first conductor, around which a honeycomb insulator made of Teflon is arranged, which has a copper shield on its outer surface as the second conductor, which in turn is covered by a shrink tube made of Teflon. The copper shield advantageously has a thickness of 0.1 mm. This embodiment is particularly suitable for use in a loudspeaker cable that has two such electrical low-frequency cables, which run parallel to one another by means of spacers and are each covered by a fabric tube. The power loss is particularly low if the first conductor of the first low-frequency cable is electrically connected to the second conductor of the second low-frequency cable and the second conductor of the first low-frequency cable is electrically connected to the first conductor of the second low-frequency cable.

Figur 1 zeigt ein erstes Ausführungsbeispiel des erfindungsgemäßen elektrischen Niederfrequenzkabels 1. Dabei sind auf einem Teflonschlauch 2, der vorteilhafterweise einen Innendurchmesser von 4 mm und einen Aussendurchmesser von 8 mm aufweisen kann zwei versilberte sechsfach-Massivleiter 3, 4 aus Kupfer angeordnet. Die sechsfach-Massivleiter 3, 4kreuzen sich dabei vorteilhafterweise unter einem Winkel von a=90° und weisen einen Abstand d=2,5 cm auf.Figure 1 shows a first embodiment of the electrical low-frequency cable 1 according to the invention. Two silver-plated six-fold solid copper conductors 3, 4 are arranged on a Teflon tube 2, which can advantageously have an inner diameter of 4 mm and an outer diameter of 8 mm. The six-fold solid conductors 3, 4 advantageously cross each other at an angle of a=90° and have a distance d=2.5 cm.

Figur 2 zeigt ein zweites Ausfuhrungsbeispiel des erfindungsgemäßen Niederfrequenzkabels 1 im Querschnitt, das sich besonders zur Verwendung als Lautsprecherkabel 5 eignet. Hierbei ist um einen massiven Kupferleiter 6 ein Wabenisolator 7 aus Teflon angeordnet, der widerum von einem Kupferschirm 8 umhüllt wird. Der Kupferschirm 8 ist vorteilhafterweise 0,1 mm dick. Um diesen Kupferschirm 8 ist ein Schrumpfschlauch 9 als zweiter Isolator aus Teflon angeordnet.Figure 2 shows a second embodiment of the low frequency cable 1 according to the invention in cross section, which is particularly suitable for use as a loudspeaker cable 5. In this case, a honeycomb insulator 7 made of Teflon is arranged around a solid copper conductor 6, which in turn is covered by a copper shield 8. The copper shield 8 is advantageously 0.1 mm thick. A shrink tube 9 is arranged around this copper shield 8 as a second insulator made of Teflon.
Zwei derartige parallel verlaufende Niederfrequenzkabel 1.1 und 1.2 bilden das Lautsprecherkabel 5, wobei jedes Niederfrequenzkabel 1.1, 1.2 durch einen Gewebeschlauch 10.1 und 10.2 umhüllt ist, die durch Abstandshalter 11 miteinander verbunden sind. Gewebeschläuche 10.1, 10.2 und Abstandshalter 11 können natürlich auch aus einem Stück gefertigt sein.Two such parallel low frequency cables 1.1 and 1.2 form the loudspeaker cable 5, whereby each low frequency cable 1.1, 1.2 is covered by a fabric hose 10.1 and 10.2, which are connected to each other by spacers 11. Fabric hoses 10.1, 10.2 and spacers 11 can of course also be made from one piece.
Ein optimales Klangerlebnis wird insbesondere dadurch erzielt, daß der erste Leiter 6.1 des ersten Niederfrequenzkabels 1.1 mit dem zweiten Leiter 8.2 des zweiten Niederfrequenzkabels 1.2 elektrisch verbunden ist und der zweite Leiter 8.1 des ersten Niederfrequenzkabels 1.1 mit dem ersten Leiter 6.2 des zweiten Niederfrequenzkabels 1.2 elektrisch verbunden ist.An optimal sound experience is achieved in particular by the fact that the first conductor 6.1 of the first low-frequency cable 1.1 is electrically connected to the second conductor 8.2 of the second low-frequency cable 1.2 and the second conductor 8.1 of the first low-frequency cable 1.1 is electrically connected to the first conductor 6.2 of the second low-frequency cable 1.2.
