Abstract

A current conducting system, in particular for lighting systems of the most varied types, has a current conducting rod, at least 50 % of the cross-section area thereof being occupied by at least two mutually-isolated metallic current conductors. Thus it is possible to work with high current densities, especially when using the current conducting system in the low voltage range. The current conducting rod is preferably round, so that holding clamps that carry electric consumers such as lamps, fans, etc. can be rotated thereon. Advantageous implementations of the holders allow the holders to swing as well, so that the user is virtually free to arrange and position the electric consumer as he wishes.

Description

Die Erfindung betrfft eine Stromleiteranordnung in Form eines stromleiterstabs, der wenigstens zwei zur Kontaktgabe frei zugängliche, durch ein Isoliermaterial isolierte metallische Stromleiter aufweist, und dessen Querschnittsfläche zu wenigstens 50% aus dem Material der Stromleiter besteht.The invention relates to a current conductor arrangement in the form of a current conductor rod which has at least two metallic current conductors which are freely accessible for contacting and insulated by an insulating material, and whose cross-sectional area consists of at least 50% of the material of the current conductors.

Aus der DE-B-1 204 731 ist eine Stromleiteranordnung bekannt, die Nuten oder Ausnehmungen aufweist, in denen jeweils ein Metallband mit geringer Querschnittsfläche eingelegt ist. Kontakte der elektrischen Verbraucher, die am Stromleiterstab befestigt sind, stehen mit den Metallbändern in der Nut des Stromleiterstabs zur Stromübertragung in elektrischem Kontakt. Eine axiale Verschiebung der Verbraucherkontakte auf der Stromleiterschiene ist zwar möglich, nicht aber eine Drehung des elektrischen Verbrauchers auf dem Außenumfang des Stromleiterstabs, da der elektrische Kontakt des Verbrauchers in die das Metallband und damit den Stromleiter aufweisende Nut bzw. Nuten eingesetzt ist. Darüber hinaus können auf Grund des einen geringen Querschnitt aufweisenden Metallbands nur geringe Stromstärken mit der bekannten Stromleiteranordnung verwendet werden.From DE-B-1 204 731 a current conductor arrangement is known which has grooves or recesses, in each of which a metal strip with a small cross-sectional area is inserted. Contacts of the electrical consumers, which are attached to the conductor bar, are in electrical contact with the metal strips in the groove of the conductor bar for current transmission. An axial displacement of the consumer contacts on the conductor rail is possible, but not a rotation of the electrical consumer on the outer circumference of the conductor rod, since the electrical contact of the consumer is inserted into the groove or grooves having the metal strip and thus the conductor. In addition, due to the metal strip having a small cross section, only small current intensities can be used with the known current conductor arrangement.

Aus der DE-A-3 120 267 ist eine Stromleiteranordnung bekannt, die Teilschienen aufweist, zwischen denen ein Isolierkörper vorgesehen ist. Dieser Isolierkörper weist zwei Rippen auf, die über die Umfangslinie der Teilschienen vorspringen. Bei dieser bekannten Stromleiteranordnung sind die beiden Rippen unbedingt erforderlich. Wären sie nicht vorhanden, würde ein Kurzschluß bei Verdrehen des Kontaktelements auftreten über das die am Kontaktelement befestigte Lampe mit Strom versorgt wird. Eine weitere Funktion der reippenförmig über die Umfangslinie der Kreisabschnitte vorstehende Isolations-Zwischenschicht besteht darin, eine Ein- und Ausschalfunktion zu erreichen. Die zur Verhinderung eines Kurzschlusses notwendigerweise erforderlichen vorstehenden Rippen weisen jedoch den Nachteil auf, daß die Kontaktteile, mit denen die Lampen an der Stromschiene befestigt sind und über die die elektrische Leitung zwischen der Lampe und der Stromschiene erfolgt, nicht gleichmäßig über den gesamten Umfang der Stromschiene verdreht werden kann, ohne daß durch die vorstehenden Rippen sowohl die mechanische Festigkeit des Klemmsitzes als auch die elektrische Kontaktierung der Lampe mit dem Stromleiter beeinträchtigt wird. Die Kontaktflächen der Lampen liegen durch die am Stromleiter vorgesehenen Rippen nicht definiert am Stromleiterstab an, sondern die Kontaktgabe erfoglt ledigleich über einen kleinen Bereich der Kontaktflächen der Lampe, so daß der Kontakt-Leitungsquerschnitt klein ist. Dasselbe gilt auch für den in der genannten Druckschrift gemachten Vorschlag, als Querschnitt des Stromleiters eine Vieleckform vorzusehen, die der Kreisquerschnittsform angepaßt ist. Auch bei einer derartigen Ausführungsform des Stromleiters beschränkt sich der Kontaktbereich zwischen der Kontaktfläche der Lampe und der Teilschiene auf die Kanten des Vielecks. Abgesehen von der Tatsache, daß dadurch ebenfalls die mechanische Festigkeit der Kontaktverbindung durch die geringere Fläche zwischen Lampenkontakt und Stromleiter und damit durch die geringere Reibung leidet, ist insbesondere auch der Kontaktübergangsquerschnitt zwischen Lampenkontakt und Stromleiteraußenseite klein, so daß kleine Übergangsquerschnitte und damit hohe Übergangswiderstände und hohe Stromdichten auftreten, die bei Verdrehung des Kontaktelements zu Funkenbildungen und Einbrennungen führen können.From DE-A-3 120 267 a current conductor arrangement is known which has partial rails between which an insulating body is provided. This insulating body has two ribs which project over the circumferential line of the partial rails. In this known current conductor arrangement, the two ribs are absolutely necessary. If they were not present, a short circuit would occur when the contact element is twisted that the lamp attached to the contact element is powered. Another function of the intermediate insulation layer protruding in the form of ribs over the circumferential line of the circular sections is to achieve a switch-on and switch-off function. The protruding ribs necessary to prevent a short circuit, however, have the disadvantage that the contact parts with which the lamps are fastened to the busbar and via which the electrical conduction between the lamp and the busbar takes place are not uniform over the entire circumference of the busbar can be rotated without the protruding ribs affecting both the mechanical strength of the clamp seat and the electrical contacting of the lamp with the current conductor. The contact surfaces of the lamps are not defined by the ribs provided on the current conductor on the current conductor rod, but the contact is made only over a small area of the contact surfaces of the lamp, so that the contact line cross section is small. The same also applies to the proposal made in the cited document to provide a polygonal shape as the cross section of the current conductor, which is adapted to the circular cross-sectional shape. Even in such an embodiment of the current conductor, the contact area between the contact surface of the lamp and the partial rail is limited to the edges of the polygon. Apart from the fact that the mechanical strength of the contact connection also suffers as a result of the smaller area between the lamp contact and the current conductor and thus due to the lower friction, the contact transition cross section between the lamp contact and the outside of the conductor is also small, so that small transition cross sections and thus high contact resistance and high Current densities occur which can lead to sparking and burn-in when the contact element is rotated.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Stromleiteranordnung zu schaffen, die bei einfachster Herstellung, Handhabung und Montage eine große Flexibilität der Anbringung, Ausrichtung und Einstellung der elektrischen Verbraucher, beispielsweise von Beleuchtungskörpern, ermöglicht, und insbesondere über den gesamten Stromleiterumfang hinweg eine sichere mechanische und elektrische Verbindung gewährleistet, ohne daß bei Verdrehen der Kontaktelemente die Gefahr eines Kurzschlusses besteht.The invention is therefore based on the object To create a conductor arrangement that allows great flexibility in the attachment, alignment and adjustment of electrical consumers, for example of lighting fixtures, with the simplest manufacture, handling and assembly, and in particular ensures a secure mechanical and electrical connection over the entire circumference of the conductor without twisting the contact elements there is a risk of a short circuit.

Ausgehend von der aus der DE-A-3 120 267 bekannten Stromleiterarnordnung wird die gestellte Aufgabe dadurch gelöst, daß das Isoliermaterial und das Material der Stromleiter eine einheitlich im Querschnitt kreisförmige Oberfläche des Strromleiterstabs bilden, und daß die frei zugänglichen Umfangsflächen der Stromleiter jeweils einen Umfangswinkel aufweisen, der kleiner als jeweils der Umfangswinkel der Isolierumfangsflächen ist.On the basis of the current conductor arrangement known from DE-A-3 120 267, the object is achieved in that the insulating material and the material of the current conductor form a surface of the current conductor rod that is circular in cross-section, and that the freely accessible peripheral surfaces of the current conductor each have a circumferential angle have, which is smaller than the circumferential angle of the insulating circumferential surfaces.

Mit der vorliegenden Erfindung ist es möglich, elektrische Verbraucher, die - wie im weiteren noch ausführlich beschrieben wird - an den Stromleiterstab angeklemmt werden, auf der Stromleiterstab-Oberfläche nicht nur axial sondern auch drehwinkelmäßig beliebig anzubringen und einzustellen. Durch die erfindungsgemäße Maßnahme, das Isolationsmaterial und das Material der Stromleiter so auszubilden, daß eine einheitlich im Querschnit kreisfömige Oberfläche gebildet wird, d. h., daß die Stromleiteroberfläche gegenüber der Isolieroberfläche des Stromleiterstabs radial nicht versetzt ist, sondern beide Materialien einen einheitlichen Kreisumfang bilden, ist sichergestellt, daß in jeder Drehlage des angeklemmten elektrischen Verbrauchers sowohl eine sichere mechanische Verbindung als auch eine gute elektrische Kontaktgabe sichergestellt ist, da die Kontaktflächen zwischen angeklemmtem Verbraucher und dem Stromleiterstab immer den definierten, maximalen Bereich aufweisen. Auf diese Weise ist das Verdrehen eines am Stromleiterstab angebrachten elektrischen Verbrauchers ohne Beeinträchtigung der mechanischen Halterung und/oder der elektrischen Kontaktgabe ohne weiteres möglich, so daß der Benutzer sowohl hinsichtlich der Achslage als auch hinsichtlich der Drehlage bei der Befestigung der elektrischen Verbraucher frei wählen und die Verbraucher auf einfache Weise in ihrer Lage beliebig anbringen bzw. verändern kann.With the present invention, it is possible to attach and adjust electrical consumers, which - as will be described in more detail below - to the conductor bar, on the conductor bar surface not only axially but also in terms of angle of rotation as desired. The measure according to the invention of designing the insulation material and the material of the current conductors in such a way that a surface with a uniform circular cross section is formed, that is to say that the current conductor surface is not radially offset from the insulating surface of the current conductor rod, but rather that both materials form a uniform circumference, is ensured that in every rotational position of the clamped electrical consumer, both a secure mechanical connection and good electrical contact are ensured, since the contact surfaces between the clamped consumer and the conductor bar always have the defined, maximum range. That way the rotation of an electrical consumer attached to the conductor rod without impairing the mechanical holder and / or the electrical contact is readily possible, so that the user can freely choose both in terms of the axial position and in terms of the rotational position in the attachment of the electrical consumer and the consumer in a simple manner can attach or change their position as desired.

Die freie Drehung des Verbrauchers bei guter elektrischer Kontaktgabe über breite Kontaktflächen hinweg ist dabei nur durch die weitere erfindungsgemäße Maßnahme möglich, daß die frei zugänglichen Umfangsflächen der Stromleiter jeweils einen Umfangswinkel aufweisen, der kleiner als die Umfangswinkel der Isolierumfangsflächen ist. Auf diese Weise ist sichergestellt, daß bei Drehen einer Halteklammer um den Stromleiterstab herum kein Kurzschluß auftritt und eine Ein- und Ausschaltwirkung dadurch auftritt, daß die Kontaktflächen der Klammer in und außer Kontakt mit den Stromleitern des Stromleiterstabs gebracht werden. Die erfindungsgemäße Stromleiteranordnung ist insbesondere für den Niedervoltbereich vorgesehen. Zur Befestigung können einfache Halteklammern verwendet werden, die entweder selbst stromleitend sind oder Innenkontaktflächen für die Herstellung des Kontakts mit den Stromleitern des Stromleiterstabs aufweisen.The free rotation of the consumer with good electrical contact across wide contact areas is only possible through the further measure according to the invention that the freely accessible peripheral surfaces of the current conductors each have a peripheral angle that is smaller than the peripheral angle of the insulating peripheral surfaces. In this way it is ensured that when a retaining clip is rotated around the conductor bar there is no short circuit and an on and off effect occurs in that the contact surfaces of the clip are brought into and out of contact with the conductor of the conductor bar. The current conductor arrangement according to the invention is intended in particular for the low-voltage range. Simple retaining clips can be used for fastening, which are either themselves electrically conductive or have internal contact surfaces for making contact with the current conductors of the current conductor rod.

Gemäß einer bevorzugten Ausführungsform der Erfindung besteht der Stromleiterstab zu wenigstens 80% aus dem Material der Stromleiter. Auf diese Weise wird der Stromleiterstab noch besser zur Leitung hoher Stromstärken ausgenutzt. Durch diesen hohen Metallanteil ist die Stromleiteranordnung daher auch im Niedervoltbereich stark belastbar.According to a preferred embodiment of the invention, the conductor bar consists of at least 80% of the material of the conductor. In this way, the conductor bar is used even better to conduct high currents. Due to this high metal content, the current conductor arrangement is therefore also able to withstand high loads in the low-voltage range.

Gemäß einer bevorzugten Ausführungsform der Erfindung wechseln die frei zugänglichen Stromleiter-Umfangsflächen und die Umfangsflächen des Isoliermaterials einander um den Umfang des Stromleiterstabs ab. Die Ausbildung der Querschnittsform der Stromleiter innerhalb des Stromleiterstabs kann dabei je nach den gegebenen Umständen oder den auftretenden Bedingungen gewählt werden. Besonders vorteilhaft ist es, den Stromleiterstab aus sich über den Kreisumfang abwechselnden Segmenten oder Teilsegmenten des Stromleiter- und Isoliermaterials zu fertigen.According to a preferred embodiment of the invention, the freely accessible current conductor peripheral surfaces and the peripheral surfaces of the insulating material alternate with one another around the circumference of the current conductor rod. The design of the cross-sectional shape of the current conductors within the current conductor rod can be selected depending on the given circumstances or the conditions that occur. It is particularly advantageous to manufacture the current conductor rod from segments or sub-segments of the current conductor and insulating material that alternate over the circumference.

Gemäß einer weiteren Ausführungsform der Erfindung weisen die frei zugänglichen Umfangsflächen der Stromleiter jeweils einen Umfangswinkel auf, der kleiner als die Umfangswinkel der Isolierumfangsflächen sind. Auf diese Weise ist es durch einfaches Drehen einer Halteklammer auf dem Stromleiterstab möglich, die Kontaktflächen der Klammer in und außer Kontakt mit den Stromleitern des Stromleiterstabs zu bringen. Dadurch ergibt sich auf einfache Weise eine Ein- und Ausschaltwirkung.According to a further embodiment of the invention, the freely accessible peripheral surfaces of the current conductors each have a peripheral angle that is smaller than the peripheral angles of the insulating peripheral surfaces. In this way, by simply turning a retaining clip on the conductor bar, it is possible to bring the contact surfaces of the clip into and out of contact with the conductor of the conductor bar. This results in a simple manner an on and off effect.

Besonders vorteilhaft ist es, wenn bei einem Stromleiterstab mit zwei metallischen Stromleitern deren frei zugängliche Umfangsflächen einen Umfangswinkel von 80° und die Isolierumfangsflächen einen Umfangswinkel von jeweils 100° aufweisen. Auf diese Weise ist sichergestellt, daß eine Halteklammer, die einen Kontaktwinkel auf dem Stromleiterstab von ca. jeweils 90° auf beiden Seiten aufweist, in der zuvor beschriebenen Weise sicher "geschaltet" werden kann.It is particularly advantageous if, in the case of a current conductor bar with two metallic current conductors, their freely accessible peripheral surfaces have a peripheral angle of 80 ° and the insulating peripheral surfaces each have a peripheral angle of 100 °. This ensures that a retaining clip, which has a contact angle on the conductor bar of approximately 90 ° on each side, can be safely "switched" in the manner described above.

Im Zusammenhang mit den zuvor beschriebenen Ausführungsbeispielen sei nochmals darauf hingewiesen, daß auch bei einem relativ großen Umfangswinkel des Isoliermaterials auf der Umfangsfläche der Stromleiteranteil bezüglich des Stromleiterstabsquerschnitts groß sein kann, da das innere des Stromleiterstabs - abgesehen von einer relativ dünnen Isolierschicht- oder -platte aus dem metallischen Stromleitermaterial bestehen kann.In connection with the previously described exemplary embodiments, it should be pointed out again that even with a relatively large circumferential angle of the insulating material on the circumferential surface, the proportion of current conductors can be large with respect to the cross-section of the conductor rod, since the inside of the conductor rod - apart from a relatively thin insulating layer or plate the metallic conductor material can exist.

Gemäß einer bevorzugten Ausführungsform der Erfindung kann der Stromleiterstab auch in gebogener Form vorliegen, wobei die metallischen Stromleiter im inneren und äusseren Krümmungsradius angeordnet sind. Die metallischen Stromleiter bilden daher bei einem gebogenen Stromleiterstab das Zug- und Druckband.According to a preferred embodiment of the invention, the current conductor rod can also be in a curved shape, the metallic current conductors being arranged in the inner and outer radius of curvature. The metallic current conductors therefore form the tension and compression band in the case of a bent current conductor rod.

Bei einer weiteren bevorzugten Ausführungsform der Erfindung ist das Material der Stromleiter mit dem Isolationsmaterial verpreßt. Auf diese Weise ergibt sich bei einfacher Herstellung eine innige Verbindung des Stromleitermetalls mit dem Isolationsmaterial.In a further preferred embodiment of the invention, the material of the current conductor is pressed with the insulation material. In this way, an intimate connection of the conductor metal results with simple manufacture with the insulation material.

Der erfindungsgemäße Stromleiterstab ist auf Grund seines einfachen Aufbaus vom Benutzer selbst je nach dessen Wünschen ablängbar. Durch einfache Konfektionierung auf der Zuschnittseite können die Stromleiterstäbe miteinander verkuppelt werden.Due to its simple construction, the current conductor bar according to the invention can be cut to length by the user himself, depending on his wishes. The conductor bars can be coupled together by simple assembly on the cut side.

Vorzugsweise ist die Oberfläche des Stromleiterstabs fein geschliffen.The surface of the conductor bar is preferably finely ground.

Die erfindungsgemäße Stromleiteranordnung ist nicht nur als leitendes Element, also als Stromleiter, sondern auch als tragendes Element für die verschiedensten Verwendungsformen geeignet. Beispielsweise ist der erfindungsgemäße Stromleiterstab als gleichzeitig tragendes und leitendes Element für Stromlauf- und Beleuchtungssysteme etwa in Form von Stativstangen, Galerieleisten, Dekorationselementen, Regal- und Trägerlementen, als Lichtschiene usw. einsetzbar. Im technischen Bereich kann der Stromleiterstab ebenfalls als gleichzeitig tragendes gleitendes Element für. Transferstraßen, als Trägerschiene für moderne Rohrpostsysteme, als Stromleiter für galvanische Anlagen oder als Kontaktschiene im Laborbereich insbesondere zum Anklemmen von Niedervoltaggregaten vorgesehen sein. Weiterhin ist es möglich, den Stromleiterstab zusätzlich als Signal- oder Alarm-Leitung für auf die Trägerspannung aufmodulierte, hochfrequente Signale, beispielsweise Alarmsignale, zu verwenden. Durch die einfache, stabile und für den Benutzer eine große Vielfalt aufweisende Konstruktion ist es möglich, die erfindungsgemäße Stromleiteranordnung praktisch unbegrenzt für die verschiedensten Anwendungsfälle vorzusehen.The current conductor arrangement according to the invention is suitable not only as a conductive element, that is to say as a current conductor, but also as a load-bearing element for a wide variety of uses. For example, the current conductor rod according to the invention can be used as a supporting and conductive element for current flow and lighting systems at the same time, for example in the form of tripod rods, gallery rails, decorative elements, shelf and support elements, as a light rail, etc. In the technical field, the conductor bar can also be used as a supporting sliding element for. Transfer lines can be provided as a carrier rail for modern pneumatic tube systems, as a current conductor for galvanic systems or as a contact rail in the laboratory area, in particular for connecting low-voltage units. It is also possible to additionally use the current conductor rod as a signal or alarm line for high-frequency signals, for example alarm signals, which are modulated onto the carrier voltage. Due to the simple, stable and for the user a wide variety of construction, it is possible to provide the current conductor arrangement according to the invention practically unlimited for a wide variety of applications.

Gemäß einer besonders vorteilhaften Ausführungsform der Erfindung werden elektrische Verbraucher, etwa Beleuchtungskörper, Ventilatoren, Motoren, Uhren, Winden, elektrische Bauelemente usw. mittels Halteklemmen am Stromleiterstab befestigt, wobei die Halteklemmen Innenkontaktflächen aufweisen, die mit den Stromleitern des Stromleiterstabs zur elektrischen Versorgung der Verbraucher in Kontakt stehen. Wie bereits erläutert, ist es bei einem runden Stromleiterstab möglich, die Halteklemmen nicht nur axial auf dem Stromleiterstab zu verschieben, sondern auch in einer zur Stromleiterstabachse senkrechten Ebene zu verdrehen. Die Halteklemmen sind analog den Wäscheklammern durch senkrechtes Einschnappen auf dem Stromleiterstab auf einfache Weise arretierbar, wobei ohne Lösen einer Schraube einerseits eine sowohl mechanisch als auch elektrisch feste Verbindung zwischen dem Stromleiterstab und der Halteklemme gewährleistet ist und andererseits eine axiale Verschiebung oder Drehung der Klemme möglich ist.According to a particularly advantageous embodiment of the invention, electrical loads, such as lighting fixtures, fans, motors, clocks, winches, electrical components, etc., are fastened to the current conductor rod by means of retaining clips, the retaining clips having internal contact surfaces which connect the current conductors of the current conductor rod to the electrical supply to the consumer Are in contact. As already explained, it is possible with a round conductor bar not only to move the retaining clamps axially on the conductor bar, but also to rotate them in a plane perpendicular to the axis of the conductor bar. Like the clothes pegs, the retaining clips can be easily locked by snapping them vertically onto the conductor bar, whereby without loosening a screw, both a mechanically and electrically firm connection between the conductor bar and the retaining clip is guaranteed and, on the other hand, axial displacement or rotation of the clip is possible .

Eine weitere Ausführungsform der Erfindung besteht darin, daß Verbindungseinrichtungen vorgesehen sind, die zwei, jeweils zwei Stromleiter aufweisende Stromleiterstäbe mechanisch und elektrisch miteinander verbinden. Auf diese Weise ist es möglich, die Stromleiter beliebig zu verlängern.A further embodiment of the invention consists in the fact that connecting devices are provided which mechanically and electrically connect two current conductor rods, each having two current conductors. In this way it is possible to extend the current conductor as desired.

Vorzugsweise ist vorgesehen, daß die Verbindungseinrichtungen aus jeweils zwei elektrisch leitenden Elementen bestehen, die mit jeweils einem Stromleiter verschraubbar sind, wobei die Elemente miteinander nicht in Berührung stehen. Da auch bei einer Weiterführung eines Stromleiterstabs die einzelnen Stromleiter elektrisch isoliert bleiben sollen, sind die Verbindungseinrichtungen daher so ausgebildet, daß jeweils ein Element immer nur die entsprechenden beiden Stromleiter zweier Stromleiterstäbe verbindet.It is preferably provided that the connecting devices each consist of two electrically conductive elements, each of which can be screwed to a current conductor, the elements not being in contact with one another. Since the individual current conductors should remain electrically insulated even when a current conductor rod is continued, the connecting devices are therefore designed such that one element always connects only the corresponding two current conductors of two current conductor rods.

Besonders vorteilhaft ist es, wenn die elektrisch leitenden Elemente Zylindersegmente sind, deren innerer Krümmungsradius im wesentlichen gleich dem Radius des Stromleiterstabs ist. Auf diese Weise ergeben sich manschettenartige Verbindungseinrichtungen, in denen die Stromleiterstäbe einen festen Halt haben und zuverlässig elektrisch miteinander verbunden sind. Vorzugsweise sind die Segmentwinkel der Zylindersegmente kleiner als 180°, um zu verhindern, daß sich die zylindersegmentförmigen Elemente nach der Montage berühren.It is particularly advantageous if the electrically conductive elements are cylinder segments whose inner radius of curvature is essentially equal to the radius of the current conductor rod. In this way, sleeve-like connecting devices result, in which the current conductor rods have a firm hold have and are reliably electrically connected. The segment angles of the cylinder segments are preferably less than 180 ° in order to prevent the cylinder segment-shaped elements from touching after assembly.

Gemäß einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die elektrisch leitenden Elemente Winkelverbinderelemente sind, deren mit den Stromleitern zu verbindende Schenkel die Form eines Zylindersegments aufweisen, dessen innerer Krümmungsradius im wesentlichen gleich dem Radius des Stromleiterstabs ist. Die Verbinderwinkel können dabei vorzuqsweise 90°, aber auch jeden anderen Winkel aufweisen. Auf diese Weise ergeben sich vielfältigste Montage- und Aufbaumöglichkeiten der erfindungsgemäßen Stromleiteranordnung. Die Verbindungseinrichtunqen können dabei auf einfache Weise mit Schrauben an den Stromleitern befestigt sein, die zuvor mit entsprechenden Gewindebohrungen versehen sind. Die Montage ist denkbar einfach, und es sind auch ohne handwerkliches Geschick und technische Kenntnis vielfältigste Formen und Konstruktionen mit der erfindungsgemäßen Stromleiteranordnung in jeder Umgebung möglich.According to a further embodiment of the invention, it is provided that the electrically conductive elements are angle connector elements, the legs of which are to be connected to the current conductors have the shape of a cylinder segment, the inner radius of curvature of which is substantially equal to the radius of the current conductor rod. The connector angles can preferably have 90 °, but also any other angle. In this way, a wide variety of assembly and construction options for the current conductor arrangement according to the invention result. The Verbindungseinrichtunqen can be easily attached to the current conductors with screws, which are previously provided with corresponding threaded holes. Installation is extremely simple, and a wide variety of shapes and constructions are possible in any environment with the current conductor arrangement according to the invention, even without manual skill and technical knowledge.

The invention is explained below with reference to the drawing, for example. Show it:

Der in Fig. 1 perspektivisch dargestellte Stromleiterstab 1 weist zwei Stromleitern 2, 3 auf, die mit einem Isoliermaterial 4 voneinander elektrisch isoliert sind. Zwischen den Stromleitern 2 und 3 befindet sich eine Zwischenschicht 5 des Isoliermaterials.The current conductor rod 1 shown in perspective in FIG. 1 has two current conductors 2, 3 which are electrically insulated from one another with an insulating material 4. An intermediate layer 5 of the insulating material is located between the current conductors 2 and 3.

Der Stromleiterstab 1 weist, wie aus den Fig. 1 und 2 zu ersehen ist, bei dem dargestellten Ausführungsbeispiel einen runden Querschnitt auf. Die Außenflächen 6, 7 der Stromleiter 2 und 3 bilden einen Teil des Umfangs des gesamten Stromleiterstabs 1. Die übrigen Umfangsbereiche des Stromleiterstabs 1 werden durch die Oberfläche des Isoliermaterials 4 gebildet.The current conductor rod 1, as can be seen from FIGS. 1 and 2, has a round cross section in the exemplary embodiment shown. The outer surfaces 6, 7 of the current conductors 2 and 3 form part of the circumference of the entire current conductor rod 1. The remaining peripheral regions of the current conductor rod 1 are formed by the surface of the insulating material 4.

Der gesamte Stromleiterstab 1 ist vorzugsweise fein geschliffen und weist eine homogene, kreisrunde Oberfläche auf. Die Stromleiter-Flächen 6, 7 liegen frei und dienen der Kontaktgabe mit im weiteren noch zu beschreibenden Halteklemmen, mit denen elektrische Verbraucher an die Stromleiteranordnung angeklemmt werden.The entire conductor bar 1 is preferably finely ground and has a homogeneous, circular surface. The current conductor surfaces 6, 7 are exposed and are used to make contact with retaining clamps to be described below, with which electrical consumers are clamped to the current conductor arrangement.

Die Form der Stromleiter 2 und 3 im Innern des Stromleiterstabs ist so ausgebildet, daß der größte Teil der Querschnittsfläche des Stromleiterstabs 1 aus dem Stromleitermaterial besteht. Auf diese Weise ergibt sich in Relation zum Querschnitt oder zum Durchmesser des Stromleiterstabs 1 ein großer Stromleiterquerschnitt, so daß der Stromleiter° stab 1 trotz seiner Kompaktheit Ströme mit großen Stromstärken leiten kann, ohne daß der Stromleiterstab 1 sich dabei erwärmt.The shape of the current conductors 2 and 3 in the interior of the current conductor rod is designed such that the largest part of the cross-sectional area of the current conductor rod 1 consists of the current conductor material. This results in a large current conductor cross-section in relation to the cross section or the diameter of the current conductor rod 1, so that the current conductor ° rod 1, despite its compactness, can conduct currents with large currents without the current conductor rod 1 heating up.

Auskehlungen 8 an den Stromleitern 2, 3 (vgl. insbesondere Fig. 2) dienen dazu, das Isoliermaterial 4 mechanisch fest mit den Stromleitern 2, 3 zu verbinden.Grooves 8 on the current conductors 2, 3 (cf. in particular FIG. 2) serve to mechanically connect the insulating material 4 to the current conductors 2, 3.

Als Alternative zu der in den Fig. 1 und 2 dargestellten Ausführungsform des Stromleiterstabs 1 besteht auch die Möglichkeit, die Stromleiter und das Isoliermaterial als Kreissegmente auszubilden. Die in Fig. 1 und 2 dargestellte Ausführungsform ist einer Ausführungsform mit Kreissegmenten jedoch dadurch überlegen, daß ein größerer Querschnittsbereich des Stromleiterstabs 1 für die Stromleiter ausgenutzt werden kann.As an alternative to the embodiment of the current conductor rod 1 shown in FIGS. 1 and 2, there is also the possibility of forming the current conductors and the insulating material as circular segments. The embodiment shown in FIGS. 1 and 2 is superior to an embodiment with circular segments in that a larger cross-sectional area of the current conductor rod 1 can be used for the current conductors.

Die Fig. 1 und 2 stellen eine Stromleiteranordnung mit zwei Stromleitern dar. Selbstverständlich ist es auch möglich, Stromleiterstäbe mit mehr als zwei Stromleitern zu schaffen, um mehrere Stromphasen zu haben und elektrische Verbraucher jeweils unabhängig voneinander mit Strom versorgen zu können, ohne daß für die mit unterschiedlichen Stromphasen versorgten elektrischen Verbraucher eigene Stromleiteranordnungen oder Stromleiterstäbe erforderlich sind.1 and 2 illustrate a conductor arrangement with two conductors. Of course, it is also possible to create conductor rods with more than two conductors in order to have several current phases and to be able to supply electrical consumers with current independently of one another without the need for Electrical consumers supplied with different current phases require their own current conductor arrangements or current conductor rods.

Je nach den jeweiligen Anwendungsfällen ist es auch möglich, den Stromleiterstab nicht rund, sondern oval, quadratisch oder rechteckig im Querschnitt auszubilden. Die runde Form hat jedoch den Vorteil, daß Halteklemmen auch um den Stromleiterstab herum gedreht und dadurch in beliebige Positionen gebracht werden können.Depending on the respective application, it is also possible to design the conductor bar not round, but oval, square or rectangular in cross section. However, the round shape has the advantage that retaining clips can also be rotated around the conductor bar and can thus be brought into any position.

Fig. 3a und 3b zeigen ein Ausführungsbeispiel für eine Halteklemme. Zwischen-zwei Halteklemmemschenkel 9 ist mittels einer Schraube 10 ein Halter 11 angeschraubt, der beispielsweise eine Lampenfassung oder eine sonstige Befestigungsmöglichkeit für einen elektrischen Verbraucher, beispielsweise für einen Ventilator, einen Motor, eine Uhr oder eine sonstige Einrichtung aufweist. Der Halter 11 ist zwischen den Halteklemmen um die Achse der Schraube 10 drehbar. Die Halteklemmenschenkel 9 sind auf der jeweiligen Innenseite so ausgebildet, daß sie auf den Stromleiterstab 1 passen. Zur Kontaktgabe sind Kontaktfedern 12 vorgesehen, die im Innern der Halteklemmschenkeln 9 angebracht sind wie im weiteren noch im einzelnen erläutert werden.3a and 3b show an embodiment for a holding clamp. Between two retaining clamp limbs 9, a holder 11 is screwed on by means of a screw 10, which holder has, for example, a lamp holder or another fastening option for an electrical consumer, for example for a fan, a motor, a clock or some other device. The holder 11 is rotatable between the holding clamps about the axis of the screw 10. The retaining clip legs 9 are on the respective Formed on the inside so that they fit on the conductor bar 1. For making contact, contact springs 12 are provided, which are attached to the inside of the holding clamp legs 9, as will be explained in more detail below.

Sowohl die Halteklemmenschenkel 9 als auch die Köntaktfedern 12 sind aus einem elastischen Material hergestellt, so daß die gesamte Halteklemme auf den Stromleiterstab 1 aufgedrückt werden kann.Both the retaining clip legs 9 and the contact springs 12 are made of an elastic material so that the entire retaining clip can be pressed onto the conductor bar 1.

In den Fig. 4a, 4b und 4c ist des besseren Verständnisses halber ein Halteklemmenschenkel nochmals als Einzelteil von den verschiedenen Seiten dargestellt. Für die Schraubverbindung ist ein Loch 13 vorgesehen. Um das Loch 13 herum befindet sich eine Ausnehmung 14, in der die Kontaktfeder 12 (vgl. die Fig. 5a, 5b und 5c) liegt. Wie insbesondere aus Fig. 5b zu ersehen ist, entspricht die Form der Kontaktfeder 12 im Bereich der Auflage auf dem Stromleiterstab der runden Form des Halteklemmenschenkels 9, wie auch aus den Fig. 3a und 3b ersichtlich ist. Die Ausbuchtung 15 des Halteklemmenschenkels ist die komplementäre Form des Stromleiterstabs 1; im dargestellten Ausführungsbeispiel ist der Stromleiterstab 1 rund, so daß die Ausbuchtung 15 kreissegmentförmig ist. In einer Nut 16 am Ende des Halteklemmemschenkels 15 liegt eine Nase 17 der Kontaktfeder 12 zur Fixierung der Kontaktfeder auch am Ende des Halteklemmenschenkels 9.4a, 4b and 4c, for the sake of better understanding, a retaining clip leg is again shown as an individual part from the different sides. A hole 13 is provided for the screw connection. Around the hole 13 there is a recess 14 in which the contact spring 12 (see FIGS. 5a, 5b and 5c) lies. As can be seen in particular from FIG. 5b, the shape of the contact spring 12 in the region of the support on the conductor bar corresponds to the round shape of the holding clamp leg 9, as can also be seen from FIGS. 3a and 3b. The bulge 15 of the retaining clip leg is the complementary form of the current conductor rod 1; In the exemplary embodiment shown, the current conductor rod 1 is round, so that the bulge 15 is in the form of a segment of a circle. In a groove 16 at the end of the holding clamp leg 15 there is a nose 17 of the contact spring 12 for fixing the contact spring also at the end of the holding clamp leg 9.

Die Kontaktfeder 12 leitet den Strom vom Stromleiterstab 1 über Metallscheiben, beispielsweise Kupferscheibeen 18 an elektrische Anschlüsse von elektrischen Verbrauchern, die an oder in den Haltern 11 angebracht sind.The contact spring 12 conducts the current from the conductor bar 1 via metal disks, for example copper washers 18, to electrical connections of electrical consumers which are attached to or in the holders 11.

Eine bevorzugte Ausführungsform des in den Fig. 3a und 3b dargestellten Halters, insbesondere dessen Befestigungsarm 19, an dem die Halteklemmenschenkel 9 mit den Kontaktfedern 12 angebracht sind, ist in den Fig. 6a und 6b dargestellt.A preferred embodiment of the holder shown in FIGS. 3a and 3b, in particular its mounting arm 19, on which the holding clamp legs 9 with the contact springs 12 are attached, is shown in Figs. 6a and 6b.

In einer Kammer 20 des Halters 11 ist ein elektrischer Verbraucher, beispielsweise ein Lampensockel angebracht. Durch zwei Bohrungen 21 ist jeweils eines der beiden Anschlußkabel durch die Wandung durchgeführt, so daß das abisolierte, freie Ende des einen Anschlußkabels in der kreisförmigen Ausnehmung 22 auf der einen Seite des Haltearms und das andere freie Ende des anderen Anschlußkabels in der kreisförmigen Ausnehmung auf der anderen Seite des Haltearms 19 liegt. Auf diese in den Ausnehmungen liegenden freien Leiterenden wird jeweils eine Metallscheibe, vorzugsweise eine gut leitende Kupferscheibe auf- bzw. eingelegt, die bei zusammengesetzter Halteklemme auf dem Teil der Kontaktfeder 12 aufliegt, der durch die Schraube 13 zwischen einem Halteklemmenschenkel einerseits und dem Haltearm 19 des Halters 11 angeordnet ist. Durch festes Verschrauben der Halteklemmenschenkel mittels der Schraube 13 wird die Scheibe 18 fest auf die in den kreisförmigen Ausnehmungen 22 liegenden Leiterenden des elektrischen Verbrauchers aufgepreßt, so daß dadurch ein guter Kontakt und ein geringer ohmscher Widerstand erzielt wird. Andererseits liegen die metallischen Scheiben 18 an den zwischen den Halteklemmenschenkeln 9 angepreßten Teilen der Kontaktfedern.12 an, die ebenfalls aus einem leitenden Material, vorzugsweise Kupfer, sind. Auf diese Weise ergibt sich trotz einer sehr guten elektrischen Verbindung zwischen den Anschlußdrähten und den Scheiben 18 eine gute Gleitwirkung zwischen den Scheiben 18 und den Kontaktfedern 12, so daß der Haltearm 19 und damit der Halter 11 bezüglich der Halteklemmenschenkel verschwenkt werden kann, ohne daß eine Schraube gelöst oder entfernt werden müßte. Auf denkbar einfache Weise ergibt sich dadurch eine grobe Vielfalt bei der Anbringung und Einstellung von elektrischen Verbrauchern, wie beispielsweise Beleuchtungskörpern, Ventilatoren usw., da durch die mögliche Drehung der Halteklemme am Stromleiterstab 1 und durch die Verschwenkung des Halters 11 bezüglich der Halteklemmen für den Benutzer jederzeit auf einfachste Weise eine Neueinstellung oder Änderung praktisch unbegrenzt möglich ist.An electrical consumer, for example a lamp base, is attached in a chamber 20 of the holder 11. Through two holes 21, one of the two connection cables is passed through the wall, so that the stripped, free end of one connection cable in the circular recess 22 on one side of the holding arm and the other free end of the other connection cable in the circular recess on the other side of the holding arm 19 is. On these free conductor ends lying in the recesses, a metal disk, preferably a highly conductive copper disk, is placed or inserted, which rests on the part of the contact spring 12 when the holding clamp is assembled, which is held by the screw 13 between a holding clamp leg on the one hand and the holding arm 19 of the Holder 11 is arranged. By firmly screwing the retaining clip legs by means of the screw 13, the washer 18 is pressed firmly onto the conductor ends of the electrical consumer lying in the circular recesses 22, so that good contact and a low ohmic resistance are thereby achieved. On the other hand, the metallic disks 18 rest against the parts of the contact springs 12 which are pressed between the holding clamp legs 9 and which are likewise made of a conductive material, preferably copper. In this way, despite a very good electrical connection between the connecting wires and the washers 18, there is a good sliding action between the washers 18 and the contact springs 12, so that the holding arm 19 and thus the holder 11 can be pivoted with respect to the retaining clip limbs without one Screw should be loosened or removed. In a very simple way, this results in a wide variety in the attachment and adjustment of electrical consumers, such as lighting fixtures, fans etc., because by the possible rotation of the holding clamp on the conductor bar 1 and by the pivoting of the holder 11 with respect to the holding clamps, a new setting or change is practically unlimited possible for the user at any time.

In den Figuren 7a, 7b und 7c sind Ausführungsbeispiele für Verbindungseinrichtungen dargestellt, mit denen runde, jeweils zwei Stromleiter 2, 3 aufweisende Stromleiterstäbe 1 sowohl mechanisch stabil als auch mit guter elektrischer Kontaktierung miteinander verbunden werden können.FIGS. 7a, 7b and 7c show exemplary embodiments for connecting devices with which round current conductor rods 1, each having two current conductors 2, 3, can be connected to one another both mechanically stable and with good electrical contact.

Fig. 7a ist für die Verbindung zweier Stromleiterstäbe 1 in gerader Richtung vorgesehen. Diese Verbindungseinrichtung gemäß Fig. 7a weist zwei im wesentlichen symmetrische Elemente 71 und 72 auf, die als Zylindersegmente ausgebildet sind. Der Innenradius der Zylindersegmente 71 und 72 entspricht im wesentlichen dem Radius des Stromleiterstabs.7a is provided for the connection of two conductor bars 1 in a straight direction. 7a has two essentially symmetrical elements 71 and 72, which are designed as cylinder segments. The inner radius of the cylinder segments 71 and 72 essentially corresponds to the radius of the conductor bar.

Die zu verbindenden Stromleiterstäbe 1 werden an den zu verbindenden Enden in den beiden Stromleitern 2 und 3 mit Gewindebohrungen versehen, die in radialer Richtung verlaufen. Die Gewindebohiungen enden noch in den jeweiligen Stromleitern 2 und 3 als Sackbohrungen.The current conductor rods 1 to be connected are provided at the ends to be connected in the two current conductors 2 and 3 with threaded bores which run in the radial direction. The threaded holes still end in the respective current conductors 2 and 3 as blind holes.

Über die zu verbindenden Enden zweier Stromleiterstäbe 1 werden dann die zylindersegmentförmigen Elemente 71 und 72 gelegt. Durch die vorbereiteten Löcher 73 und 74 im oberen Element 71 und durch entsprechende, aus der Figur nicht ersichtliche Löcher im unteren Element 72 werden Schrauben hindurchgeführt, die in die Gewindebohrungen der Stromleiter 2 und 3 der Stromleiterstäbe 1 eingeschraubt und damit befestigt werden. Dadurch ergibt sich eine manschettenartige Verbindung zweier Stromleiterstäbe 1.The cylinder segment-shaped elements 71 and 72 are then placed over the ends of two current conductor rods 1 to be connected. Screws are passed through the prepared holes 73 and 74 in the upper element 71 and through corresponding holes in the lower element 72 (not shown in the figure), which are screwed into the threaded bores of the current conductors 2 and 3 of the current conductor rods 1 and are thus fastened. This creates a cuff-like connection two conductor bars 1.

Um sicherzustellen, daß die beiden Stromleiterstäbe miteinander nicht in elektrischen Kontakt kommen, weisen die Zylindersegmente einen Segmentwinkel auf, der kleiner als 180° ist, so daß sich die Segmente nach der Befestigung an den Stromleiterstäben nicht berühren, sondern ein Zwischenraum frei bleibt. Aufgrund der Sackgewindelöcher ist es auch nicht möglich, daß eine elektrische Verbindung der Stromleiter über die Schrauben entsteht.In order to ensure that the two conductor bars do not come into electrical contact with one another, the cylinder segments have a segment angle that is less than 180 °, so that the segments do not touch after attachment to the conductor bars, but a space remains free. Because of the blind threaded holes, it is also not possible for the current conductors to be electrically connected via the screws.

Fig. 7b zeigt eine Verbindungseinrichtung für eine winklige Verbindung. Der Winkel ist in dem dargestellten Ausführungsbeispiel 90°. Die Winkel der beiden Winkelelemente 75 und 75 weisen beidschenklig wiederum die Zylindersegmentform sowie die Schraubenlöcher 77, 78 auf, wie sie bereits anhand der in Fig. 7a dargestellten Ausführungsform beschrieben wurden. Die zu verbindenden Stromleiterstäbe 1 können dabei auf Gehrung geschnitten sein. Erforderlich ist jedoch lediglich, daß die Enden der zu verbindenden Stromleiterstäbe 1 soweit in die Winkelverbinderelemente hereinragen, daß die Schrauben in die entsprechenden Gewindebohrungen ihrer Stromleiter 2 und 3 eingeschraubt werden können.7b shows a connection device for an angled connection. The angle is 90 ° in the illustrated embodiment. The angles of the two angle elements 75 and 75 in turn have the cylindrical segment shape on both legs and the screw holes 77, 78, as have already been described with reference to the embodiment shown in FIG. 7a. The conductor bars 1 to be connected can be mitred. All that is required, however, is that the ends of the conductor bars 1 to be connected protrude into the angle connector elements to such an extent that the screws can be screwed into the corresponding threaded bores of their conductor 2 and 3.

Fig. 7c zeigt ebenfalls eine rechtwinklige Verbindungseinrichtung mit Verbindungselementen 79 und 80. Die Verbindung der Stromleiterstäbe 1 erfolgt wie bei den in den Fig. 7a und 7b dargestellten und in Zusammenhang damit beschriebenen Verbindungseinrichtungen. Die in Fig. 7c dargestellte Verbindungseinrichtung ist jedoch zusätzlich zu der in Fig. 7b dargestellten Verbindungseinrichtung dann erforderlich, wenn eine Verbindung der Stromleiterstäbe in eine Richtung gewünscht ist, die aus der Ebene herauszeigt, die durch die Schenkel der in Fig. 7b dargestellten Verbindungseinrichtung aufgespannt ist.FIG. 7c also shows a right-angled connecting device with connecting elements 79 and 80. The connection of the current conductor rods 1 takes place as in the connecting devices shown in FIGS. 7a and 7b and described in connection therewith. The connection device shown in FIG. 7c is, however, required in addition to the connection device shown in FIG. 7b if connection of the current conductor rods is desired in a direction which points out of the plane spanned by the legs of the connection device shown in FIG. 7b is.

In den in Fig. 7b und 7c dargestellten Winkelverbindungseinrichtungen ist der Verbindungswinkel 90°. Gewünschtenfalls können auch Winkelverbindungseinrichtungen mit anderen Verbindungswinkeln als 90°, z. B. mit einem Verbindungswinkel von 60°, vorgesehen sein.In the angle connection devices shown in FIGS. 7b and 7c, the connection angle is 90 °.
