Description

Die vorliegende Erfindung betrifft ein Stromleitprofil für ein Stromschienensystem gemäß dem Oberbegriff des Anspruch 1.The present invention relates to a Stromleitprofil for a busbar system according to the preamble of claim 1.

Stromschienensysteme finden in der Beleuchtungstechnik in vielfacher Form Verwendung, da sie im Vergleich zu fest installierten oder eingebauten Leuchten eine hohe Flexibilität bei der individuellen Planung von Beleuchtungsanordnungen für spezifische Anforderungen bieten. Üblicherweise bestehen Stromschienensysteme aus mehreren einzelnen Elementen, die nach dem Baukasten-Prinzip zusammengesetzt werden, sodass die gesamte Anordnung in einfacher Weise an die zu beleuchtenden Räumlichkeiten angepasst werden kann. Hierbei können nicht nur zweidimensionale sondern auch dreidimensionale Strukturen gebildet werden.Busbar systems are used in lighting technology in many forms, as they offer a high degree of flexibility in the individual planning of lighting arrangements for specific requirements compared to permanently installed or built-in luminaires. Usually busbar systems consist of several individual elements, which are assembled according to the modular principle, so that the entire arrangement can be easily adapted to the space to be illuminated. Here, not only two-dimensional but also three-dimensional structures can be formed.

Ein Stromschienensystem der eingangs geschilderten Art, welches auf dem Markt sehr erfolgreich ist, ist in der DE 100 25 647 A1 der Anmelderin beschrieben. Wie bei nahezu jedem Stromschienensystem wird auch hier das Grundgerüst durch Tragschienen gebildet, die zu der gewünschten Struktur zusammengesetzt werden und der Halterung der Stromversorgungs- und Steuerleitungen sowie der einzelnen Leuchten dienen. Die Drähte sind hierbei innerhalb eines so genannten Stromleitprofils angeordnet, welches in Längsrichtung verlaufende und von einer Kontaktierungsseite zugängliche Nuten aufweist, in der die Drähte aufgenommen sind. Die Besonderheit des aus der DE 100 25 647 A1 bekannten Systems besteht dabei darin, dass das Stromleitprofil durch mehrere ineinander gesetzte Kunststoffelemente gebildet wird, die an ihren Endbereichen derart ausgestaltet sind, dass sie mit entsprechenden Vorsprüngen überlappend ineinander greifen und in dem Verbindungsbereich den Nuten entsprechende und zur Kontaktierungsseite hin offene Kanäle bilden. Hierdurch wird die Möglichkeit geschaffen, über die gesamte Länge des Stromschienensystems hinweg Leuchten frei anzuordnen, wobei trotz allem ein aus Sicherheitsgründen geforderter Berührungsschutz gewährleistet ist.A busbar system of the type described above, which is very successful in the market, is in the DE 100 25 647 A1 the applicant described. As with almost every busbar system, the basic framework is formed here by mounting rails, which are assembled to the desired structure and serve to hold the power supply and control lines and the individual lights. The wires are in this case arranged within a so-called Stromleitprofils, which has longitudinally extending and accessible from a contacting side grooves, in which the wires are accommodated. The peculiarity of the DE 100 25 647 A1 known system consists in the fact that the Stromleitprofil is formed by a plurality of nested plastic elements which are configured at their end portions such that they overlap with corresponding projections overlapping each other and form in the connection region of the grooves corresponding to the contacting and open channels. As a result, the possibility is created, freely arranged over the entire length of the busbar system away lights, despite all a required for safety reasons contact protection is guaranteed.

Bei den in der DE 100 25 647 A1 beschriebenen Kunststoffelementen zur Bildung des Stromleitprofils handelt es sich um verhältnismäßig kurze Kunststoffteile, welche wie oben beschrieben zu der länglichen Struktur zusammengefügt werden. Die Herstellung dieser Kunststoffelemente erfolgt üblicherweise im Spritzgussverfahren. In der Zwischenzeit wurden allerdings neuartige Herstellungsverfahren entwickelt, mit deren Hilfe auch verhältnismäßig komplexe Kunststoffelemente über eine größere Länge hinweg hergestellt werden können. Die Verwendung solcher längeren Kunststoffteile zum Bilden eines Stromleitprofils würde den Vorteil mit sich bringen, dass die Montage des Systems aufgrund der reduzierten Bauteile deutlich erleichtert werden würde. Auf der anderen Seite besteht dann das Problem, dass sich die Kunststoffteile im Vergleich zu der üblicherweise aus Metall bestehenden Tragschiene verhältnismäßig stark ausdehnen bzw. zusammenziehen, falls Temperaturänderungen auftreten. Eine einfache Verlängerung der aus der DE 100 25 647 A1 bekannten Kunststoffteile ist dementsprechend nicht ohne Weiteres möglich.In the in the DE 100 25 647 A1 described plastic elements to form the Stromleitprofils are relatively short plastic parts, which are assembled as described above to the elongated structure. The production of these plastic elements is usually carried out by injection molding. In the meantime, however, novel manufacturing processes have been developed with which Help even relatively complex plastic elements over a greater length can be produced. The use of such longer plastic parts to form a Stromleitprofils would bring the advantage that the installation of the system would be much easier due to the reduced components. On the other hand, then there is the problem that the plastic parts in comparison to the usually made of metal support rail relatively strong expand or contract, if temperature changes occur. A simple extension of the DE 100 25 647 A1 Accordingly, known plastic parts is not readily possible.

In der EP 1 353 415 A1 , der DE 10 2007 026 907 A1 , der EP 0 938 168 A2 und der US 3,337,697 A sind Stromschienensysteme gezeigt, die entsprechende Vorrichtungen aufweisen, um die unterschiedlich starke Ausdehnung auszugleichen.In the EP 1 353 415 A1 , of the DE 10 2007 026 907 A1 , of the EP 0 938 168 A2 and the US 3,337,697 A Busbar systems are shown having appropriate devices to compensate for the different degrees of expansion.

Der vorliegenden Erfindung liegt nun die Aufgabe zu Grunde, eine neuartige Lösung zum Realisieren eines Stromleitprofils für ein Stromschienensystem zu bilden, bei dem ebenso die Probleme im Hinblick auf eine unterschiedliche Längenausdehnung im Vergleich zu der aus Metall bestehenden Tragschiene vermieden werden.The present invention is based on the object to form a novel solution for realizing a Stromleitprofils for a busbar system, in which also the problems in terms of a different longitudinal extent compared to the metal support rail are avoided.

Die Aufgabe wird durch ein Stromleitprofil für ein Stromschienensystem mit den Merkmalen des Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a Stromleitprofil for a busbar system with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Lösung beruht auf dem Gedanken, auch bei längeren einstückigen Kunststoffelementen zum Bilden eines Stromleitprofils einen Längenausgleich zu ermöglichen. Dies wird dadurch geschaffen, dass das Kunststoffelement einen speziell ausgestalteten Ausgleichsbereich aufweist, der eine Relativbewegung zweier durch diesen Ausgleichsbereich miteinander verbundenen Abschnitte des Kunststoffelements zulässt.The solution according to the invention is based on the idea of enabling length compensation even with longer one-piece plastic elements for forming a current-conducting profile. This is achieved by virtue of the fact that the plastic element has a specially designed compensation region which permits a relative movement of two sections of the plastic element which are interconnected by this compensation region.

Dementsprechend wird gemäß der vorliegenden Erfindung ein Stromleitprofil für ein Stromschienensystem vorgeschlagen, wobei das Stromleitprofil in Längsrichtung verlaufende und von einer Kontaktierungsseite her zugängliche Nuten zur Aufnahme von Drähten für die Stromversorgung und/oder Übertragung von Steuersignalen aufweist. Erfindungsgemäß weist das Stromleitprofil ein längliches Kunststoffelement auf, welches zumindest einen Längenausgleichsbereich aufweist, der in Längsrichtung des Stromleitprofils eine Relativbewegung zweier durch den Längenausgangsbereich miteinander verbundene Abschnitte des Kunststoffelements zulässt.Accordingly, according to the present invention, a Stromleitprofil proposed for a busbar system, wherein the Stromleitprofil extending in the longitudinal direction and accessible from a contacting side grooves for receiving wires for the power supply and / or transmission of control signals. According to the invention, the current-conducting profile has an elongate plastic element which has at least one length compensation region which permits a relative movement of two sections of the plastic element connected to one another in the longitudinal direction of the current-conducting profile.

Durch die Nutzung des erfindungsgemäßen Längenausgleichsbereich wird nunmehr die Möglichkeit eröffnet, auch längere Kunststoffelemente zum Bilden eines Stromleitprofils einzusetzen. Ein entsprechendes Stromschienensystem kann dementsprechend in deutlich einfacherer und kostengünstigerer Weise montiert werden.The use of the length compensation area according to the invention now opens up the possibility of using longer plastic elements to form a current-conducting profile. A corresponding busbar system can Accordingly, be mounted in a much simpler and cheaper way.

Gemäß einem besonders bevorzugten Ausführungsbeispiel der vorliegenden Erfindung ist vorgesehen, dass die durch den Längenausgleichsbereich miteinander verbundenen Abschnitte mit Vorsprüngen derart ineinander greifen, dass über den gesamten Längenausgleichsbereich hinweg den Nuten entsprechende und zu der Kontaktierungsseite hin offene Kanäle gebildet sind. Dementsprechend ist auch in dem Längenausgleichsbereich die Kontaktierung der Drähte und damit eine Anordnung einer Leuchte ermöglicht, wobei trotz allem die einschlägigen Sicherheitsnormen erfüllt werden. Vorzugsweise sind hierbei an dem Stirnbereich eines Abschnitts Vorsprünge ausgebildet, welche in an dem gegenüberliegenden Abschnitt ausgebildete Ausnehmungen eingreifen.According to a particularly preferred embodiment of the present invention, it is provided that the portions interconnected by projections with the length compensation region interlock with one another in such a way that channels corresponding to the grooves and open towards the contacting side are formed over the entire length compensation region. Accordingly, the contacting of the wires and thus an arrangement of a lamp is also in the length compensation range allows, despite all the relevant safety standards are met. In this case, projections are preferably formed on the end region of a section, which engage in recesses formed on the opposite section.

Der Längenausgleichsbereich selbst wird vorzugsweise durch eine das Kunststoffelement durchbrechende Fuge gebildet, welche an ihren Seiten zwei die beiden Abschnitte miteinander verbindende Federbereiche aufweist. Diese können insbesondere V-förmig ausgebildet sein. Ferner kann vorgesehen sein, dass an dem Längenausgleichsbereich Begrenzungselemente ausgebildet sind, welche eine Ausdehnung dieses Bereichs auf eine vorgegebene Länge begrenzen. Ein zu starkes Zusammenziehen des Kunststoffelements wird auf diese Weise vermieden. Das Kunststoffelement selbst kann an den Längsseiten Arme aufweisen, mit deren Hilfe eine Befestigung an einer Tragschiene ermöglicht wird.The length compensation region itself is preferably formed by a gap which penetrates the plastic element and has on its sides two spring regions interconnecting the two sections. These may be formed in particular V-shaped. Furthermore, provision may be made for limiting elements to be formed on the length compensation region which delimit an extension of this region to a predetermined length. Too much contraction of the plastic element is avoided in this way. The plastic element itself may have on the longitudinal sides of arms, by means of which an attachment to a mounting rail is made possible.

Figur 1 zeigt zunächst eine Schnittdarstellung durch ein Stromschienensystem gemäß der vorliegenden Erfindung. Das System besteht zunächst aus einem aus Metall bzw. Blech gebildeten U-förmigen, länglichen Trägerelement 1, das nachfolgend als Stromschiene bezeichnet wird, welches mit seinem Mittelschenkel zwei durch nicht dargestellte Befestigungsmittel an einem Träger beispielsweise einer Decke oder einer Raumwand befestigbar ist. Die Abdeckung der nach unten offenen Stromschiene erfolgt in denjenigen Bereichen, in denen keine Leuchten angeordnet werden, durch eine mit dieser verrastbaren Abdeckschiene 4. FIG. 1 shows first a sectional view through a busbar system according to the present invention. The system consists initially of a formed from metal or sheet U-shaped, elongated support member 1, which is hereinafter referred to as a busbar, which is fastened with its center leg two fastening means not shown on a support such as a ceiling or a room wall. The cover of the downwardly open busbar is in those areas where no lights are arranged by a latchable with this cover rail. 4

Für die Stromversorgung bzw. Übermittlung von Steuerinformationen bzw. Steuerbefehlen für die Leuchten sind mehrere Leiterdrähte 61 bis 65 und 71 bis 76 vorgesehen, die an den Innenseiten der beiden Seitenwände 3a und 3b in Längsrichtung der Stromschiene 1 verlaufen. Die Halterung der Leiterdrähte 61 bis 65 und 71 bis 76 erfolgt mit Hilfe von in die Seitenbereiche der Stromschiene 1 eingelegten Trägerelementen 8 aus einem isolierenden Material. Die über Trägerelemente 8 weisen jeweils entsprechende Nuten 9 auf, in welche die nichtisolierten Leiterdrähte 61 bis 65 und 71 bis 76 des Stromschienensystems eingelegt werden. Die Form der Nuten 9 ist dabei derart gewählt, dass ein Berührungsschutz gewährleistet wird. Dies bedeutet, dass die Nuten 9 derart bemessen sind, dass ein versehentliches Berühren der Leiterdrähte 61 bis 65 und 71 bis 76 ausgeschlossen ist. Die Leiterdrähte 61 bis 65 und 71 bis 76 werden lediglich von einem in die Stromschiene 1 einzuführenden - nicht dargestellten - Drehabgriff kontaktiert, der in die jeweiligen Nuten 9 der Trägerelementen 8 einzuführende Kontakte aufweist und über diese die Leuchte mit Strom und Steuerinformationen versorgt. Das gesamte Stromschienensystem setzt sich dann aus einer Vielzahl solcher einzelnen Stromschienen zusammen.For the power supply or transmission of control information or control commands for the lights a plurality of conductor wires 6 1 to 6 5 and 7 1 to 7 6 are provided, which extend on the inner sides of the two side walls 3 a and 3 b in the longitudinal direction of the bus bar 1. The holder of the conductor wires 6 1 to 6 5 and 7 1 to 7 6 takes place with the aid of inserted into the side regions of the busbar 1 support elements 8 made of an insulating material. The carrier elements 8 each have corresponding grooves 9, in which the non-insulated conductor wires 6 1 to 6 5 and 7 1 to 7 6 of the busbar system are inserted. The shape of the grooves 9 is chosen such that a contact protection is ensured. This means that the grooves 9 are dimensioned such that an inadvertent contact of the conductor wires 6 1 to 6 5 and 7 1 to 7 6 is excluded. The conductor wires 6 1 to 6 5 and 7 1 to 7 6 are contacted only by one to be introduced into the busbar 1 - not shown - Drehabgriff having inserted into the respective grooves 9 of the support elements 8 contacts and on this the lamp with power and control information provided. The entire busbar system is then composed of a plurality of such individual busbars.

Bei dem aus der DE 100 25 647 A1 bekannten Stromschienensystem werden mehrere, verhältnismäßig kurze Trägerelemente zu einem sog. Stromleitprofil für die Halterung der Leiterdrähte zusammengefügt. Durch dieses modulare Zusammenfügen und eine spezielle Ausgestaltung der Endbereiche der Trägerelemente werden in Abständen von ca. 30 cm bis 60 cm Ausgleichsstellen gebildet, die eine "Wärmeatmung" des Stromleitprofils ermöglichen. Dies ist deshalb von Bedeutung, da sich die aus Kunststoff bestehenden Isolierstoffträger bei Wärme wesentlich stärker als die darin eingebetteten Leiterdrähte und die metallische Tragschiene ausdehnen oder bei Kälte sich entsprechend stärker zusammenziehen. Durch das modulare Zusammenfügen der Trägerelemente wird gewährleistet, dass auch bei einem Zusammenziehen bzw. Ausdehnen der Kunststoffteile durchgehende Nuten zur Aufnahme der Leiterdrähte gebildet werden und dementsprechend zu jedem Zeitpunkt ein ausreichender Berührungsschutz gegeben ist. Somit wird letztendlich ermöglicht, dass die Leuchten an einer beliebigen Stelle in die Stromschiene eingesetzt werden können. Die angesprochene spezielle Ausgestaltung der Endbereiche der Isolierstoffträger kann der DE 100 25 647 A1 entnommen werden.In the from the DE 100 25 647 A1 known busbar system several, relatively short carrier elements are joined together to form a so-called. Stromleitprofil for holding the conductor wires. By means of this modular assembly and a special design of the end regions of the carrier elements, equalization points are formed at intervals of approximately 30 cm to 60 cm, which enable "thermal ventilation" of the current-conducting profile. This is important because the plastic insulating material carrier is much stronger in heat than that in it expand embedded conductor wires and the metallic support rail or contract in the cold correspondingly stronger. The modular assembly of the support elements ensures that even when a contraction or expansion of the plastic parts continuous grooves for receiving the conductor wires are formed and, accordingly, at all times sufficient protection against contact is given. Thus, it is ultimately possible that the lights can be used anywhere in the busbar. The mentioned special design of the end portions of the insulating material can the DE 100 25 647 A1 be removed.

Anstelle dieser verhältnismäßig kurzen Trägerelemente kommen bei dem System der vorliegenden Erfindung nunmehr längere Kunststoffelemente zum Einsatz. Derartige längere Elemente können beispielsweise mit einer neuartigen Technologie erstellt werden, die unter der Bezeichnung EXJECTION-Technologie bekannt wurde. Diese ermöglicht es, extrusionsähnliche Profile zu spritzen, welche über ihre Länge hinweg gesehen spritztechnische Merkmale aufweisen können, beispielsweise Durchbrüche, Querrippen, Querschnittsänderungen und dergleichen. Auf diese Weise wird die Herstellung eines länglichen Stromleitprofils erleichtert, gleichzeitig müssen allerdings Maßnahmen getroffen werden, welche das zuvor beschriebene Ausdehnen und Zusammenziehen bei Wärmeänderungen ermöglichen. Hierzu werden speziell ausgestaltete Kunststoffelemente eingesetzt, wie sie zunächst in den Figuren 2 bis 4 dargestellt sind.Instead of these relatively short carrier elements, longer plastic elements are now used in the system of the present invention. Such longer elements can be created for example with a novel technology, which became known as EXJECTION technology. This makes it possible to inject extrusion-like profiles which, viewed over their length, can have injection-molding characteristics, for example breakthroughs, transverse ribs, cross-sectional changes and the like. In this way, the production of an elongated Stromleitprofils is facilitated, however, at the same time measures must be taken, which allow the previously described expansion and contraction with heat changes. For this purpose, specially designed plastic elements are used, as they first in the FIGS. 2 to 4 are shown.

Diese allgemein mit dem Bezugszeichen 10 versehenen Kunststoffelemente weisen zunächst wiederum in Querschittsrichtung gesehen und - wie in Figur 4 dargestellt - ein wellenförmiges Profil auf, durch welche nebeneinander in Längsrichtung verlaufende Nuten 9 gebildet sind, in denen die hier nicht dargestellten Drähte aufgenommen werden. Diese Nuten 9 sind zur Innenseite der Tragschiene 1 hin offen und erlauben dementsprechend eine Kontaktierung der Drähte durch ein entsprechendes Kontaktierungselement, beispielsweise durch den aus der DE 100 25 647 A1 bekannten Drehabgriff.These generally provided with the reference numeral 10 plastic elements have first seen again in the cross-sectional direction and - as in FIG. 4 shown - a wave-shaped profile, by which side by side extending in the longitudinal direction grooves 9 are formed, in which the wires not shown here are added. These grooves 9 are open to the inside of the support rail 1 and accordingly allow a contacting of the wires by a corresponding contacting element, for example by the from DE 100 25 647 A1 known Drehabgriff.

Die Besonderheit besteht nunmehr darin, dass das wellenförmige Profil des Kunststoffelements 10 in einem bestimmten Abschnitt 15, der nachfolgend als Längenausaleichsabschnitt bezeichnet wird, unterbrochen ist. Die Unterbrechung erfolgt durch eine Fuge 16, welche sich in Querrichtung erstreckt und dementsprechend das Kunststoffelement 10 in zwei benachbarte Abschnitte 20, 30 unterteilt, welche über den Längenausgleichsbereich 15 miteinander verbunden sind. Genaugenommen erfolgt die Verbindung zwischen beiden Bereichen 20 und 30 an zwei länglichen Seitenarmen 11 des Kunststoffelements 10, deren Aufgabe es zunächst ist, das Kunststoffelement 10 in der Tragschiene 2 zu halten. Die Seitenarme 11 werden hierbei wie in Figur 1 dargestellt in die entsprechend profilierten Seitenwände 3a, 3b der Tragschiene 1 eingeschoben. In dem Längenausgleichsbereich 15 sind nunmehr auch diese Seitenarme 11 unterbrochen, derart, dass lediglich eine Verbindung über einen V-förmigen Abschnitt 17 verbleibt, wobei die beiden Seitenarme 18 des V-förmigen Abschnitts 17 im Außenbereich schmaler ausgebildet sind und ihre Breite zur Mitte hin zunimmt.The special feature consists in the fact that the wave-shaped profile of the plastic element 10 in a certain section 15, which is hereinafter referred to as Längenausaleichsabschnitt interrupted. The interruption is effected by a joint 16, which extends in the transverse direction and accordingly divides the plastic element 10 into two adjacent sections 20, 30, which are connected to one another via the length compensation region 15. Strictly speaking, the connection between the two regions 20 and 30 takes place two elongate side arms 11 of the plastic element 10, the task of which is first to hold the plastic element 10 in the support rail 2. The side arms 11 are here as in FIG. 1 shown in the corresponding profiled side walls 3a, 3b of the support rail 1 is inserted. In the length compensation region 15, these side arms 11 are now also interrupted, such that only one connection remains over a V-shaped section 17, wherein the two side arms 18 of the V-shaped section 17 are narrower in the outer region and their width increases towards the center ,

Diese besondere Ausgestaltung der Arme 18 des V-förmigen Abschnitts 17 ermöglicht eine Relativverschiebung zwischen beiden Abschnitten 20 und 30, wie dies in den Figuren 6a und 6b dargestellt ist. Figur 6a zeigt dabei die Anordnung im Normalzustand, in dem das Kunststoffelement 10 in der Tragschiene 1 montiert ist, wobei die Montage vorzugsweise derart erfolgt, dass das Kunststoffelement 10 mit seinen stirnseitigen Enden fest an der Tragschiene 1 befestigt wird. Erhöht sich nunmehr die Temperatur, so hat dies zur Folge, dass sich das Kunststoffelement 10 bzw. die Abschnitte 20, 30 ausdehnen. Die Ausdehnung wird nunmehr dadurch ausgeglichen, dass - wie in Figur 6b dargestellt - sich die beiden Abschnitte 20 und 30 in dem Längenausgleichsbereich 15 aufeinander zu bewegen, was durch ein entsprechendes Verformen des V-förmigen Abschnitts 17 ermöglicht wird. Die Längsausdehnung der Trennfuge 16 reduziert sich hierbei, erlaubt allerdings, dass die Abschnitte 20 und 30 selbst weiterhin die durchgehenden Nuten 9 zur Aufnahme der Drähte 6 bilden können.This particular embodiment of the arms 18 of the V-shaped portion 17 allows a relative displacement between the two sections 20 and 30, as shown in the Figures 6a and 6b is shown. FIG. 6a shows the arrangement in the normal state in which the plastic element 10 is mounted in the support rail 1, wherein the assembly is preferably carried out such that the plastic element 10 is fixedly secured with its front ends to the support rail 1. Increases now the temperature, this has the consequence that the plastic element 10 and the sections 20, 30 expand. The expansion is now compensated by the fact that - as in FIG. 6b shown - the two sections 20 and 30 in the length compensation area 15 to move toward each other, which is made possible by a corresponding deformation of the V-shaped portion 17. The longitudinal extent of the parting line 16 is reduced here, but allows the sections 20 and 30 themselves to continue to form the continuous grooves 9 for receiving the wires 6.

Eine Besonderheit liegt nunmehr darin, dass an dem Stirnende des Abschnitts 20 stiftförmige Vorsprünge 21 ausgebildet sind, welche in entsprechende Ausnehmungen an dem zweiten Abschnitt 30 eingreifen. Durch diese Vorsprünge 21 werden auch im Bereich der Trennfuge 16 die Nuten 9 des Stromleitprofils weitergeführt, und zwar unabhängig davon, ob eine zusätzliche Ausdehnung in Längsrichtung vorliegt oder nicht. Dies ist in den Figuren 6a und 6b gezeigt, bei denen sich die Vorsprünge 21 grundsätzlich bis zu dem gegenüberliegenden Stirnbereich des Abschnitts 30 erstrecken.A special feature lies in the fact that at the front end of the section 20 pin-shaped projections 21 are formed, which engage in corresponding recesses on the second portion 30. Through these projections 21, the grooves 9 of the Stromleitprofils be continued even in the region of the parting line 16, regardless of whether an additional extension in the longitudinal direction or not. This is in the Figures 6a and 6b shown, in which the projections 21 in principle extend to the opposite end region of the portion 30.

Ferner sind Mittel vorgesehen, mit denen ein übermäßiges Zusammenziehen der Abschnitte 20 und 30, also eine übermäßige Vergrößerung der Trennfuge 16 verhindert wird. Diese Abgrenzungsmittel sind an einem der beiden Seitenarme 11 ausgebildet und in den Figuren 7a und 7b dargestellt. Es handelt sich hierbei um einen zusätzlichen Steg 19, der am Ende des V-förmigen Bereichs 17 angeordnet ist und an seinen Enden zwei hakenartige Elemente 19a und 19b aufweist. Diese Haken 19a, 19b übergreifen seitliche Vorsprünge 25 und 35 an den Abschnitten 20 und 30, wie insbesondere in Figur 3 gezeigt ist. Ziehen sich nunmehr aufgrund einer Temperatursenkung die Abschnitte 20 und 30 zusammen, was aufgrund der Befestigung der Enden des Kunststoffelements 10 an der Tragschiene 1 eine Ausdehnung der Trennfuge 16 zur Folge hat, so begrenzen die Vorsprünge 19a und 19b ein übermäßiges Ausdehnen der Fuge 16, was ggf. zur Folge hätte, dass die Vorsprünge 21 nicht mehr über die gesamte Länge hinweg die Nuten 9 des Stromleitprofils fortführen. Es liegt also ein mechanischer Stopp vor, der ein zu weites Auseinanderziehen der Fuge 16 verhindert.Furthermore, means are provided with which an excessive contraction of the sections 20 and 30, ie an excessive enlargement of the parting line 16 is prevented. These delimiting means are formed on one of the two side arms 11 and in the FIGS. 7a and 7b shown. This is an additional web 19, which is arranged at the end of the V-shaped portion 17 and has at its ends two hook-like elements 19a and 19b. These hooks 19a, 19b engage over lateral projections 25 and 35 at the portions 20 and 30, in particular in FIG. 3 is shown. Pull now due to a decrease in temperature, the sections 20 and 30 together, which has an extension of the parting line 16 results due to the attachment of the ends of the plastic element 10 to the support rail 1 result, so limit the projections 19a and 19b, an excessive expansion of the joint 16, what possibly would have the consequence that the projections 21 no longer continue over the entire length of the grooves 9 of the Stromleitprofils. So there is a mechanical stop, which prevents too wide pulling the joint 16.

Letztendlich wird also durch das erfindungsgemäße Kunststoffelement wiederum ein Stromleitprofil geschaffen, welches über die gesamte Länge eines Stromschienensystems hinweg eine Kontaktierung der Drähte und damit ein Montieren einer Leuchte ermöglicht, gleichzeitig allerdings auch in geeigneter Weise auf Temperaturschwankungen reagieren kann. Dadurch, dass das Stromleitprofil nunmehr durch ein einstückiges Kunststoffelement gebildet ist, wird die Herstellung und insbesondere auch die Montage des Systems vereinfacht.Ultimately, therefore, a Stromleitprofil is again created by the plastic element according to the invention, which allows contacting the wires over the entire length of a busbar system and thus mounting a lamp, but at the same time can also respond in a suitable manner to temperature fluctuations. The fact that the Stromleitprofil is now formed by a one-piece plastic element, the production and in particular the installation of the system is simplified.
