Abstract

The current rail system uses current rails (10) with a hollow outer conductor profile (12) around the outside of an inner conductor profile (14) electrically separated from the outer conductor profile by an intermediate insulation layer (16) and accessed via slits (46) in the outer conductor profile. At least two abutting current rails are joined together via a coupling device with plug pins fitting into the hollow bores of the inner conductor profiles and spring clips cooperating with the outer conductor profiles.

Description

Die Erfindung betrifft ein Niedervolt-Stromschienensystem.The invention relates to a low-voltage busbar system.

Niedervolt-Stromschienensysteme werden insbesondere in der Beleuchtungstechnik eingesetzt. Niedervolt-Stromschienensysteme dienen dabei dem Energietransport von einer Stromquelle zu einer Leuchte.Low-voltage track systems are used particularly in lighting technology. Low-voltage track systems serve to transport energy from a power source to a luminaire.

DE-PS 38 17 133, von der der Oberbegriff des Anspruchs 1 ausgeht, beschreibt ein Niedervolt-Stromschienensystem mit einer Stromschiene, die ein eine Außenwand bildendes hohlgeformtes Außenleiterprofil und ein von dem Außenleiterprofil im wesentlich umgebenes Innenleiterprofil aufweist, das gegenüber dem Außenleiterprofil durch eine Isolierung elektrisch getrennt ist, wobei das Innenleiterprofil durch einen in Achsrichtung des Außenleiterprofils verlaufenden Schlitz zugänglich ist. Das bekannte Niedervolt-Stromschienensystem hat jedoch den Nachteil, daß sich gegeneinandergestossene Stromschienen nur schlecht verbinden lassen.DE-PS 38 17 133, from which the preamble of claim 1 is based, describes a low-voltage busbar system with a busbar which has a hollow-shaped outer conductor profile which forms an outer wall and an inner conductor profile which is substantially surrounded by the outer conductor profile and which is insulated from the outer conductor profile is electrically separated, the inner conductor profile being accessible through a slot running in the axial direction of the outer conductor profile. However, the well-known low-voltage busbar system the disadvantage that it is difficult to connect busbars that have collided with one another.

Der Erfindung liegt die Aufgabe zugrunde, ein Niedervolt-Stromschienensystem zur Verfügung zu stellen, das eine leichte Verbindbarkeit mindestens zweier Stromschienen erlaubt.The invention has for its object to provide a low-voltage busbar system that allows easy connectivity of at least two busbars.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Patentanspruchs 1.This object is achieved according to the invention with the features of patent claim 1.

Gemäß der Erfindung ist das Innenleiterprofil ein Hohlprofil, das einen innenliegenden Kanal aufweist. Dieser Kanal erlaubt das Einstecken von Steckerstiften eines Steckerelements, mit denen Innenleiterprofile mindestens zweier Stromschienen elektrisch miteinander verbindbar sind. Da der Kanal durchlaufend ausgebildet ist, kann eine Stromschiene an jeder beliebigen Stelle abgeschnitten und mit einer weiteren Stromschiene und ggf. auch mit einem Bogenstück verbunden werden. Zur elektrischen Verbindung der Außenleiterprofile sind Federklammern vorgesehen, die die Außenleiterprofile an ihrer Außenseite klemmend umfassen. Durch das Steckerelement werden nicht nur zwei oder mehrere gegeneinandergestoßene Stromschienen mechanisch miteinander verbunden, sondern es wird auch eine elektrische Verbindung zwischen den Innenleiterprofilen hergestellt.According to the invention, the inner conductor profile is a hollow profile which has an internal channel. This channel allows the plug-in pins of a plug element with which inner conductor profiles of at least two busbars can be electrically connected to one another. Since the channel is continuous, a conductor rail can be cut off at any point and connected to a further conductor rail and possibly also to an arc piece. For the electrical connection of the outer conductor profiles, spring clips are provided which clamp the outer conductor profiles on their outside. The plug element not only mechanically connects two or more busbars that collide with one another, but also creates an electrical connection between the inner conductor profiles.

Bei dem Zusammenstecken von Stromschienen zu einem Versorgungssystem werden zunächst die Steckerelemente in die Kanäle von aneinander angrenzenden Stromschienen gesteckt. Dadurch haben aneinandergestoßene Stromschienen schon so viel gegenseitigen Halt, daß sie allenfalls noch mit einer Hand gehalten werden müssen.When the busbars are plugged together to form a supply system, the plug elements are first plugged into the channels of adjacent busbars. As a result, busbars that have collided with one another have so much mutual support that they still have to be held with one hand.

Mit der freien Hand kann ein Benutzer dann leicht auch durch Aufstecken einer Federklammer die Außenleiterprofile elektrisch verbinden, wobei die Federklammer auch die mechanische Festigkeit der Verbindungsstelle erhöht. Insbesondere wenn das Außenleiterprofil im Querschnitt eine im wesentlichen kreisförmige Außenkontur aufweist, können gegeneinandergestossene Stromschienen durch einfaches Aufklippsen einer Federstahlklammer elektrisch miteinander verbunden werden.With the free hand, a user can then easily electrically connect the outer conductor profiles by plugging in a spring clip, the spring clip also increasing the mechanical strength of the connection point. In particular if the outer conductor profile has an essentially circular outer contour in cross section, busbars that are butted against one another can be electrically connected to one another simply by clipping on a spring steel clip.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung im Zusammenhang mit der Zeichnung.Further advantageous refinements and developments of the invention result from the subclaims and from the description in connection with the drawing.

Im folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.In the following an embodiment of the invention will be explained with reference to the drawings.

Es zeigen:

Show it:

a busbar of the low-voltage busbar system according to the invention in a section transverse to the longitudinal axis of the busbar, and
Fig. 2
the busbar in Figure 1 with a connecting device in a section along the line II-II in Figure 1.

Die in Figur 1 gezeigte Stromschiene 10 besteht aus einem Außenleiterprofil 12 und einem Innenleiterprofil 14, zwischen denen als Isolierung 16 ein Polycarbonat-Isolierungsprofil angeordnet ist.The busbar 10 shown in Figure 1 consists of an outer conductor profile 12 and an inner conductor profile 14, between which a polycarbonate insulation profile is arranged as insulation 16.

Das Außenleiterprofil 12 ist ein stranggepreßtes Aluminiumprofil, das eine im wesentlichen kreisförmige Außenkontur 18 aufweist. Im Innern des Außenleiterprofils 12 ist ein längslaufender, im Querschnitt im wesentlichen kreisförmiger Gang 20 ausgebildet, der eine in Längsrichtung des Außenleiterprofils 12 verlaufende durchgehende Öffnung 22 aufweist ist. Die Öffnung 22, die zur Profilaußenseite offen ist und deren Wände 24,26 parallel zu einer Mittenebene 28 des Außenleiterprofils 12 verlaufen, erstreckt sich über einen Winkelbereich von etwa 60°.The outer conductor profile 12 is an extruded aluminum profile which has an essentially circular outer contour 18. In the interior of the outer conductor profile 12 there is a longitudinal passage 20, which is essentially circular in cross section and which has a continuous opening 22 running in the longitudinal direction of the outer conductor profile 12. The opening 22, which is open to the outside of the profile and whose walls 24, 26 run parallel to a central plane 28 of the outer conductor profile 12, extends over an angular range of approximately 60 °.

Im Innern des Gangs 20 ist koaxial zu der Längsachse 30 des Außenleiterprofils 12 das Innenleiterprofil 14 angeordnet, das ein stranggepreßtes Aluminiumhohlprofil ist. Der im Innern des Innenleiterprofils 14 ausgebildete Kanal 32 hat einen kreisförmigen Querschnitt und erstreckt sich koaxial zu der Längsachse 30 des Außenleiterprofils 12. An dem Innenleiterprofil 14, dessen Außenkontur 34 im wesentlichen die Form eines Zylinders beschreibt, ist ein radialer Vorsprung 36 vorgesehen, der im Bereich der Öffnung 22 des Außenleiterprofils 12 angeordnet ist und sich nach radial außen erstreckt. Der Vorsprung 36 weist an seiner Außenseite eine ebene Kontaktfläche 38 auf, die quer zur Mittenebene 28 der Stromschiene 10 verläuft.The inner conductor profile 14, which is an extruded aluminum hollow profile, is arranged coaxially to the longitudinal axis 30 of the outer conductor profile 12 in the interior of the passage 20. The channel 32 formed in the interior of the inner conductor profile 14 has a circular cross section and extends coaxially to the longitudinal axis 30 of the outer conductor profile 12. On the inner conductor profile 14, the outer contour 34 of which essentially describes the shape of a cylinder, a radial projection 36 is provided, which in the Area of the opening 22 of the outer conductor profile 12 is arranged and extends radially outward. The projection 36 has on its outside a flat contact surface 38 which extends transversely to the center plane 28 of the busbar 10.

Die zur elektrischen Trennung des Außenleiterprofils 12 vom Innenleiterprofil 14 vorgesehene Isolierung 16 weist einen im Querschnitt im wesentlichen U-förmigen Verlauf auf, wobei die von einem Bogenabschnitt 40 der Isolierung 16 abstehenden Schenkel 42,44 im Bereich der Öffnung 22 parallel zu den Wänden 24,26 der Öffnung verlaufen und sich nach radial außen so weit erstrecken, daß sie die kreisförmige Außenkontur 18 des Außenleiterprofils 12 ergänzen. Die Isolierung 16 füllt den Zwischenraum zwischen Innenleiterprofil 14 und Außenleiterprofil 12 vollständig aus. Zwischen den Schenkeln 42,44 erstreckt sich ein in Achsrichtung des Außenleiterprofils 12 verlaufender Schlitz 46, durch den das Innenleiterprofil 14 von außen zugänglich ist. Die Isolierung 16 und das Innenleiterprofil 14 sind derart aufeinander abgestimmt, daß die ebene Kontaktfläche 38 die gesamte Breite des längslaufenden Schlitzes 46 überspannt. Die ebene Kontaktfläche 38 ist gegenüber der Außenkontur 18 des Außenleiterprofils 12 nach innen zurückversetzt.The insulation 16 provided for the electrical separation of the outer conductor profile 12 from the inner conductor profile 14 has an essentially U-shaped profile in cross section, the legs 42, 44 projecting from an arch section 40 of the insulation 16 in the region of the opening 22 parallel to the walls 24, 26 of the opening and extend radially outward so far, that they complement the circular outer contour 18 of the outer conductor profile 12. The insulation 16 completely fills the space between the inner conductor profile 14 and the outer conductor profile 12. A slot 46 extends in the axial direction of the outer conductor profile 12 and through which the inner conductor profile 14 is accessible from the outside between the legs 42, 44. The insulation 16 and the inner conductor profile 14 are matched to one another in such a way that the flat contact surface 38 spans the entire width of the longitudinal slot 46. The flat contact surface 38 is set back inwards relative to the outer contour 18 of the outer conductor profile 12.

In Figur 2 ist die Stromschiene 10 zusammen mit einer Verbindungsvorrichtung 50 gezeigt, die aus einem Steckerelement 52 und einer Federklammer 54 besteht.In Figure 2, the busbar 10 is shown together with a connecting device 50, which consists of a plug element 52 and a spring clip 54.

Das Steckerelement 52 weist als Steckerstifte zwei entgegengesetzt gerichtete Lamellenstecker 56,58 auf, die jeweils mehrere an einer Spitze 60 und an ihrem Ende 62 miteinander verbundene, radial federnde Zungen oder Lamellen 64 aufweisen. Die Lamellenstecker sind miteinander über ein Zentralstück 66 verbunden. Das in Fig. 2 gezeigte Steckerelement 52 ist ein langgestrecktes Steckerelement zur geradlinigen Verbindung zweier stirnseitig gegeneinandergestoßener Stromschienen 10. Es ist jedoch auch möglich, die Lamellenstecker eines Steckerelements winklig zueinander anzuordnen, so daß zu verbindende Stromschienen unter einem Winkel zueinander verlaufen. Ferner ist es möglich, an einem Zentralstück mehrere Lamellenstecker sternförmig zueinander anzuordnen, so daß mehrere Stromschienen miteinander verbindbar sind.The plug element 52 has, as plug pins, two oppositely directed lamella plugs 56, 58, each of which has a plurality of radially resilient tongues or lamellas 64 connected to one another at a tip 60 and at their end 62. The lamella plugs are connected to one another via a central piece 66. The plug element 52 shown in FIG. 2 is an elongated plug element for the straight connection of two busbars 10 that are butted against one another on the end face. However, it is also possible to arrange the lamella plugs of a plug element at an angle to one another so that busbars to be connected run at an angle to one another. Furthermore, it is possible to arrange a plurality of lamellar plugs in a star shape relative to one another on a central piece, so that a plurality of busbars can be connected to one another.

Die in Fig. 2 gezeigte äußere Federklammer 54 ist rohrförmig ausgebildet, wobei sie jedoch einen längslaufenden Schlitz aufweist, der ein Aufbiegen der Schenkel der Federklammer 54 erlaubt. Die Schenkel der Federklammer 54 sind derart nach innen vorgespannt, daß die Federklammer 54 in einem auf eine Stromschiene 10 geklippsten Zustand das Außenleiterprofil 12 der Stromschiene 10 klemmend umfaßt. Wenn mit einer Federklammer mehrere Stromschienen miteinander verbunden werden sollen, ist es möglich, die Federklammer sternförmig auszuführen.The outer spring clip 54 shown in FIG. 2 is tubular, but it has a longitudinal slot that allows the legs of the spring clip 54 to bend open. The legs of the spring clip 54 are prestressed inwards such that the spring clip 54, when clipped onto a busbar 10, clamps the outer conductor profile 12 of the busbar 10. If several busbars are to be connected to each other with a spring clip, it is possible to design the spring clip in a star shape.

Im Betrieb stellen Steckerelemente 52 elektrische Verbindungen zwischen Innenleiterprofilen 14 gegeneinandergestoßener Stromschienen 10 her. Federklammern 54 bewirken eine elektrische Verbindung der Außenleiterprofile 12. Auf diese Weise kann ein zweipoliges Stromversorgungssystem insbesondere für Niedervoltbeleuchtungen aufgebaut werden. Die im Zusammenhang mit Fig. 2 beschriebene Verbindungsvorrichtung 50 besteht aus zwei mechanisch voneinander getrennten Elementen. Mit den beschriebenen Stromschienen 10 sind aber auch Verbindungsvorrichtungen verwendbar, bei denen Steckerelmente 52 und Federklammern 54 mittels eines Ioslierkörpers zu einem mechanisch zusammenhängenden Bauteil zusammengefaßt sind.In operation, plug elements 52 make electrical connections between inner conductor profiles 14 of busbars 10 that collide with one another. Spring clips 54 effect an electrical connection of the outer conductor profiles 12. In this way, a two-pole power supply system can be constructed, in particular for low-voltage lighting. The connecting device 50 described in connection with FIG. 2 consists of two mechanically separate elements. With the busbars 10 described, however, connecting devices can also be used, in which plug elements 52 and spring clips 54 are combined to form a mechanically connected component by means of an isomer body.
