Description

Für Beleuchtungszwecke werden seit einiger Zeit immer häufiger Niedervoltspannungssysteme von vorzugsweise 12 Volt verwendet.Low voltage systems, preferably 12 volts, have been used increasingly for lighting purposes for some time.

Für die Stromverteilung kann dabei mit nicht- isolierten Stromschienen gearbeitet werden, die eine freie Leitungsführung ermöglichen und damit eine beliebige Anordnung von Lichtquellen erlaubt. Die Anordnung der blanken und relativ gross dimensionierten Stromschienen ergibt in einem bewohnten Raum eine wenig ästethische Ambiance.For the current distribution, non-insulated busbars can be used, which enable free cable routing and thus allow any arrangement of light sources. The arrangement of the bare and relatively large busbars results in a less aesthetic ambience in an inhabited room.

Die Erfindung bezweckt, für eine solche Niedervoltanlage ein Leitersystem zu schaffen, das zufolge seiner kleinen Abmessungen ein gefälligeres Aussehen besitzt und zudem eine grössere Freiheit in der Leitungsführung im Raum und längs Wänden ermöglicht.The invention aims to provide a conductor system for such a low-voltage system, which, due to its small dimensions, has a more pleasing appearance and also allows greater freedom in the routing of lines in space and along walls.

Die Erfindung schlägt vor, die beiden Stromleiter einer Leitung koaxial anzuordnen, wobei der Aussenleiter das mechanisch tragende Element bildet. Der Aussenleiter hat dabei vorzugsweise einen Durchmesser von höchstens 8 mm.The invention proposes to arrange the two current conductors of a line coaxially, the outer conductor forming the mechanically load-bearing element. The outer conductor preferably has a diameter of at most 8 mm.

Ausführungsbeispiele der Erfindung werden anhand der Zeichnung näher erläutert. In dieser zeigen:

  • Fig. 1,2,3 die Verbindung zweier koaxialer Leiterstücke,
  • Fig. 4 - 9 einige Beispiele von Leiteranordnungen.
Embodiments of the invention are explained in more detail with reference to the drawing. In this show:
  • 1,2,3 the connection of two coaxial conductor pieces,
  • Fig. 4-9 some examples of conductor arrangements.

In Fig. 1 sind zwei koaxial ausgebildete Leiterstücke 1 mittels eines ebenso ausgebildeten Verbindungsstükes 6 elektrisch und mechanisch miteinander verbunden. Jedes Leiterstück 1 besteht aus einem Aussenleiter 2, einem Innenleiter 4 und einem dazwischen liegenden Isolator 3. Auf einem abgesetzten Teil des Aussenleiters 2 sitzt ein Kontaktlamellenring 5. Beim Verbindungsstück 6 ist der einen Durchmesser von höchstens 8 mm aufweisende Aussenleiter mit 11 und der Isolator mit 10 bezeichnet. Auf dem Innenleiter 8, der als nach beiden Seiten vorstehender Stutzen ausgebildet ist sitzen Kontaktlamellenringe 9. Die mechanische Verbindung von Leiterstück 1 und Verbindungsstück 6 erfolgt über ein Gewinde 11, während eine für die hohen Ströme erforderliche gute elektrische Verbindung durch die Kontaktlamellenringe 5 und 9 gewährleistet wird.In Fig. 1, two coaxially formed conductor pieces 1 are electrically and mechanically connected to one another by means of an equally designed connecting piece 6. Each conductor piece 1 consists of an outer conductor 2, an inner conductor 4 and an insulator 3 located in between. A contact lamella ring 5 sits on a stepped part of the outer conductor 2. The connector 6 has the outer conductor with a diameter of at most 8 mm with 11 and the insulator with Designated 10. Contact lamellar rings 9 sit on the inner conductor 8, which is designed as a protruding piece on both sides Thread 11, while a good electrical connection required for the high currents is ensured by the contact plate rings 5 and 9.

Eine solche Koaxial- Leitung ermöglicht eine sehr kompakte und gefällige Stromversorgung für Niedervolt- Lichtquellen.Such a coaxial line enables a very compact and pleasing power supply for low-voltage light sources.

Die Oberfläche der Aussenleiter 2 und 7 lässt sich den jeweiligen Wünschen anpassen, z.B. durch Verchromen oder durch einen Farbüberzug, der sich in besonders kratzfester Ausführung durch Einbrennen einer elektrostatisch aufgebrachten Pulverschicht herstellen lässt.The surface of the outer conductors 2 and 7 can be adapted to the respective requirements, e.g. by chrome plating or by a color coating, which can be produced in a particularly scratch-resistant version by baking an electrostatically applied powder layer.

Die Fig. 4 - 9 zeigen einige Ausführungsmöglichkeiten für ein Leitersystem.4-9 show some possible embodiments for a conductor system.

Bei den Fig. 6 und 7 ist je ein Verbindungsblock 13 vorgesehen, in welchem 3 bzw 4 Verbindungsstücke,analog zu einer Hälfte des in Fig. 3 dargestellten, eingesetzt in welche eine entsprechende Zahl von Leitungsstücken 1 eingeschraubt werden können, so dass ein T- Stück (Fig. 6) bzw. ein Kreuzstück (Fig. 7) entsteht.6 and 7, a connecting block 13 is provided, in which 3 or 4 connecting pieces, analogous to one half of the one shown in FIG. 3, are inserted, into which a corresponding number of line pieces 1 can be screwed, so that a T- Piece (Fig. 6) or a cross piece (Fig. 7).

Fig. 8 zeigt schematisch einen Adapter 14, mit welchem die vom Transformator kommenden Speiseleiter 15 an die Koaxial- Leitung 1 angeschlossen werden.Fig. 8 shows schematically an adapter 14 with which the feeder 15 coming from the transformer are connected to the coaxial line 1.
