Description

Die vorliegende Erfindung betrifft eine Leuchte, insbesondere für ein zumindest zwei Leuchten aufweisendes Lichtband. Die Erfindung betrifft außerdem ein mit zumindest zwei solchen Leuchten ausgestattetes Lichtband. Ferner betrifft die Erfindung eine Endkappe für eine solche Leuchte bzw. für ein solches Lichtband.The present invention relates to a luminaire, in particular for a luminous band having at least two luminaires. The invention also relates to a light strip equipped with at least two such lights. Furthermore, the invention relates to an end cap for such a luminaire or for such a light band.

Als Lichtband wird beispielsweise eine bandartige Aneinanderreihung von einzelnen Leuchten bezeichnet. Hierbei weist ein Lichtband zum Beispiel eine Länge ab 3 m auf. Innerhalb eines Lichtbands ist auch die Verkabelung für die Energieversorgung von Leuchtmitteln der einzelnen Leuchten vorgesehen. Eine durchgehende Verkabelung ermöglicht es, lediglich an einer Stelle das Lichtband mit Energie zu versorgen, indem die Verkabelung an eine Gebäudeenergieversorgung angeschlossen wird.As a light band, for example, a band-like juxtaposition of individual lights is called. Here, a light band, for example, a length from 3 m. Within a light band, the wiring for the power supply of light sources of the individual lights is provided. A continuous wiring makes it possible to supply the light band with energy only in one place by connecting the wiring to a building energy supply.

Die einzelnen Leuchten, die innerhalb eines derartigen Lichtbands in ihrer Längsrichtung aufeinanderfolgen, weisen üblicherweise jeweils eine Tragschiene auf, die einen U-förmigen Schienenquerschnitt besitzt. Hierzu weist die Tragschiene ein Basisprofil und zwei davon abstehende Stegprofile auf, wobei das Basisprofil einer offenen Seite des Schienenprofils gegenüberliegt und mit Hilfe eines Geräteträgers verschließbar ist. An diesem Geräteträger können sich dann zumindest ein Leuchtmittel oder ein anderes, insbesondere elektrisches, Gerät befinden. Über die Tragschiene erfolgt üblicherweise die Aufhängung bzw. Abhängung der jeweiligen Leuchte bzw. des Lichtbands an einer Gebäudedecke.The individual lamps, which follow one another in such a light band in their longitudinal direction, usually each have a mounting rail, which has a U-shaped rail cross-section. For this purpose, the support rail on a base profile and two projecting web profiles, wherein the base profile of an open side of the rail profile opposite and can be closed by means of a device carrier. At least one illuminant or another, in particular electrical, device can then be located on this device carrier. About the mounting rail is usually the suspension or suspension of the respective light or the light band to a building ceiling.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Leuchte bzw. für ein damit ausgestattetes Lichtband eine verbesserte Ausführungsform anzugeben, die sich insbesondere dadurch auszeichnet, dass sie eine erhöhte Betriebssicherheit besitzt.The present invention is concerned with the problem of providing an improved embodiment for a luminaire or for a light strip equipped therewith, which is characterized in particular by the fact that it has an increased operational reliability.

Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

Die Erfindung beruht auf dem allgemeinen Gedanken, in der Tragschiene ein Stromführungsprofil anzuordnen, das bezüglich der Tragschiene ein separates Bauteil darstellt und das mehrere von einem Trägerabschnitt abstehende Stegabschnitte aufweist. Dabei sind diese Stegabschnitte am Trägerabschnitt so angeordnet, dass sie unter Ausbildung von Lücken zueinander beabstandet sind und zueinander parallel verlaufen. Wenigstens einer dieser Stegabschnitte trägt wenigstens einen elektrischen Leiter, der zu einer der Lücken seitlich freistehend oder offen, also kontaktierbar ist. Ein derartiges Stromführungsprofil kann besonders preiswert als Endlosmaterial hergestellt werden. Durch Ablängen des Endlosmaterials lassen sich die Stromführungsprofile vereinzeln, derart, dass sie in die jeweilige Tragschiene einsetzbar sind. Problematisch kann dabei der Umstand sein, dass an den axialen Enden des Stromführungsprofils die elektrischen Leiter frei oder offen sind. Dies widerspricht den üblichen Sicherheitsbestimmungen und kann bei unsachgemäßer Montage zu einem Kurzschluss oder zu einer Gefahrenquelle für den jeweiligen Monteur führen. Um dies zu vermeiden, ist das Stromführungsprofil erfindungsgemäß zumindest an einem seiner Längsenden mit einer Endkappe versehen. Diese ist bezüglich des Stromführungsprofils als separates Bauteil konzipiert und dementsprechend an das Stromführungsprofil angebaut. Ferner ist die jeweilige Endkappe so konzipiert, dass sie den wenigstens einen elektrischen Leiter axial abdeckt. Die vorstehend genannten Gefahren sind dadurch signifikant vermindert. Die Endkappe ist hierzu elektrisch isolierend ausgestaltet. Zweckmäßig besteht sie aus einem elektrisch isolierenden Material, wie zum Beispiel Kunststoff.The invention is based on the general idea of arranging a current-carrying profile in the mounting rail, which is a separate component with respect to the mounting rail and which has a plurality of web sections projecting from a support section. In this case, these web portions are arranged on the support portion so that they are spaced apart to form gaps and parallel to each other. At least one of these web sections carries at least one electrical conductor, which is laterally free-standing or open, that is to say contactable, to one of the gaps. Such a current-carrying profile can be produced particularly inexpensively as continuous material. By cutting the endless material to length, the current-carrying profiles can be singulated so that they can be inserted into the respective mounting rail. The problem may be the fact that the electrical conductors are free or open at the axial ends of the current-carrying profile. This contradicts the usual safety regulations and can lead to a short circuit or a source of danger for the respective installer if improperly installed. To avoid this, the current-carrying profile according to the invention is provided with an end cap at least at one of its longitudinal ends. This is designed with respect to the current-carrying profile as a separate component and attached accordingly to the current-carrying profile. Further, the respective end cap is designed to axially cover the at least one electrical conductor. The aforementioned dangers are thereby significantly reduced. The end cap is designed for this purpose electrically insulating. Suitably, it consists of an electrically insulating material, such as plastic.

Gemäß einer vorteilhaften Ausführungsform kann die Endkappe für den jeweiligen von ihr axial abgedeckten elektrischen Leiter einen Ausweichraum aufweisen, in den der jeweilige elektrische Leiter axial eintauchen kann, wenn er sich thermisch bedingt stärker ausdehnt als das übrige Stromführungsprofil. Üblicherweise wird das Stromführungsprofil aus Kunststoff hergestellt, zum Beispiel durch Extrusion oder Strangpressen. Im Unterschied dazu sind die davon aufgenommenen elektrischen Leiter aus Metall, vorzugsweise aus Kupfer bzw. aus einer Kupferlegierung, hergestellt. Während des Betriebs der jeweiligen Leuchte bzw. des jeweiligen Lichtbands kann es zu einer signifikanten Temperaturerhöhung im Stromführungsprofil kommen. Einerseits besitzen Kunststoff und Metall stark unterschiedliche thermische Ausdehnungskoeffizienten. Andererseits kann das einzelne Stromführungsprofil innerhalb der jeweiligen Leuchte eine vergleichsweise große Länge aufweisen. In der Folge kann es bei den üblichen Temperaturzunahmen dazu kommen, dass sich der jeweilige elektrische Leiter an den axialen Enden des Stromführungsprofils deutlich herausbewegt, also aus dem Kunststoffkörper des Stromführungsprofils axial herausragt. Durch die hier vorgeschlagene Modifikation der Endkappe taucht der sich axial aus dem Kunststoffkörper des Stromführungsprofils herausbewegende Leiter in besagten Ausweichraum ein, wodurch weiterhin die elektrisch isolierende Abdeckung durch die Endkappe gewährleistet ist. Gleichzeitig wird durch diese Konstruktion der Endkappe sichergestellt, dass der sich ausdehnende elektrische Leiter die Endkappe nicht vom Kunststoffkörper des Strömungsprofils wegdrücken oder trennen kann.According to an advantageous embodiment, the end cap for the respective electrical conductor axially covered by it can have an escape space into which the respective electrical conductor can dip axially if it expands more thermally than the rest of the current-carrying profile. Usually, the current-carrying profile is made of plastic, for example by extrusion or extrusion. In contrast, the electrical conductors received therefrom are made of metal, preferably of copper or of a copper alloy. During operation of the respective luminaire or the respective light band, a significant increase in temperature can occur in the current-carrying profile. On the one hand, plastic and metal have very different thermal expansion coefficients. On the other hand, the individual current-carrying profile can have a comparatively long length within the respective luminaire. As a result, in the case of the usual temperature increases, the respective electrical conductor can move out clearly at the axial ends of the current-carrying profile, ie protrude axially from the plastic body of the current-carrying profile. Due to the modification of the end cap proposed here, the conductor which moves axially out of the plastic body of the current-carrying profile emerges in said escape space, whereby the electrically insulating cover is furthermore ensured by the end cap. At the same time, this construction of the end cap ensures that the expanding electrical conductor can not push away or separate the end cap from the plastic body of the airfoil.

Besonders vorteilhaft ist hierbei eine Weiterbildung, bei welcher die Endkappe für jeden von ihr axial abgedeckten elektrischen Leiter einen separaten Ausweichraum aufweist. Hierdurch wird vermieden, dass bei mehreren axial aus dem Kunststoffkörper des Stromführungsprofils abstehenden elektrischen Leitern eine direkte Kontaktierung benachbarter Leiter auftritt.Particularly advantageous in this case is a development in which the end cap has a separate escape space for each of its axially covered electrical conductors. This avoids that in the case of several electrical conductors projecting axially from the plastic body of the current-carrying profile, a direct contacting of adjacent conductors occurs.

Gemäß einer anderen vorteilhaften Ausführungsform kann die Endkappe zumindest einen Zapfen aufweisen, der axial in eine der Lücken des Stromführungsprofils einsteckbar ist und durch Kraftschluss und/oder Reibschluss an den Stegabschnitten fixiert ist. Diese Bauweise vereinfacht die Montage der Endkappe am Stromführungsprofil, da die Endkappe lediglich auf das jeweilige axiale Ende des Stromführungsprofils aufgesteckt werden muss.According to another advantageous embodiment, the end cap may have at least one pin, which is axially inserted into one of the gaps of the current-carrying profile and is fixed by frictional connection and / or frictional engagement on the web portions. This construction simplifies the assembly of the end cap on the current guide profile, since the end cap must be attached only to the respective axial end of the current-carrying profile.

Entsprechend Fig. 1 umfasst ein nur teilweise dargestelltes Lichtband 1 zumindest zwei Leuchten 2, die in einer durch einen Doppelpfeil angedeuteten Längsrichtung 3 des Lichtbands 1 bzw. der jeweiligen Leuchte 2 unmittelbar aufeinanderfolgen. Diese Längsrichtung 3 definiert dabei gleichzeitig eine Axialrichtung oder Achsrichtung des Lichtbands 1 sowie der jeweiligen Leuchte 2 und deren Komponenten. Dabei stoßen benachbarte Leuchten 2 innerhalb des Lichtbands 1 stirnseitig bzw. axial aneinander. Entsprechende Stoßgrenzen sind in Fig. 1 mit 4 bezeichnet. Es ist klar, dass die Übergänge benachbarter Leuchten 2 bzw. diese Stoßgrenzen 4 bei fertiggestelltem Lichtband 1 mit entsprechenden Dichtmitteln staubdicht und/oder feuchtigkeitsdicht ausgestaltet sein können. Im Bereich dieser Stoßgrenzen 4 erstreckt sich jeweils ein, durch eine geschweifte Klammer gekennzeichneter Verbindungsbereich, in dem die benachbarten Leuchten aneinander befestigt sind.Corresponding Fig. 1 comprises a partially shown light band 1 at least two lights 2, which follow one another directly in a direction indicated by a double arrow longitudinal direction 3 of the light band 1 and the respective lamp 2. This longitudinal direction 3 defines at the same time an axial direction or axial direction of the light band 1 and the respective lamp 2 and its components. In this case, adjacent lights 2 abut each other within the light band 1 at the front or axially. Corresponding impact limits are in Fig. 1 denoted by 4. It is clear that the transitions of adjacent lights 2 or these impact limits 4 with finished light strip 1 with corresponding sealing means dustproof and / or moistureproof can be configured. In the region of these impact boundaries 4 extends in each case one, characterized by a brace connection region in which the adjacent lights are attached to each other.

Entsprechend Fig. 2 umfasst eine solche Leuchte 2 eine Tragschiene 6, an der zumindest ein Geräteträger 7 befestigbar ist. Die Tragschiene 6 und der Geräteträger 7 sind langgestreckt, d. h., sie sind deutlich, also mindestens dreimal oder mindestens fünfmal länger als breit und hoch. Der Geräteträger 7 ist außerdem flach, d. h., er ist deutlich, also mindestens dreimal oder mindestens fünfmal breiter und länger als hoch. Im Beispiel besitzt der Geräteträger 7 die gleiche Länge wie die Tragschiene 6. Hierdurch ist die jeweilige Leuchte 2 auch als Einzelleuchte außerhalb des Lichtbands 1 verwendbar. Ebenso ist es denkbar, an einer Tragschiene 6 mehrere Geräteträger 7 zu befestigen. Sofern die Leuchte 2 in einem solchen Lichtband 1 verwendet wird, ist es auch möglich, Geräteträger 7 zu verwenden, die länger sind als die einzelnen Tragschienen. Innerhalb des Lichtbands 1 können einzelne Geräteträger 7 auch gleichzeitig an mehreren Tragschienen 6 befestigt sein.Corresponding Fig. 2 Such a luminaire 2 comprises a mounting rail 6, to which at least one device carrier 7 can be fastened. The support rail 6 and the equipment carrier 7 are elongated, ie, they are clear, so at least three times or at least five times longer than wide and high. The equipment carrier 7 is also flat, ie, it is clear, so at least three times or at least five times wider and longer than high. In the example, the device carrier 7 has the same length as the mounting rail 6. As a result, the respective lamp 2 as a single luminaire outside the light band 1 can be used. It is also conceivable to fasten a plurality of equipment carriers 7 to a mounting rail 6. If the luminaire 2 is used in such a light band 1, it is also possible to use device carrier 7, which are longer than the individual mounting rails. Within the light band 1, individual device carriers 7 may also be fastened to a plurality of mounting rails 6 at the same time.

Im gezeigten Beispiel der Fig. 2 weist der Geräteträger 7 an einer der Tragschiene 6 zugewandten Oberseite eine elektrische Kontakteinrichtung 8 sowie zumindest eine elektronische Baugruppe 9 auf. An einer von der Tragschiene 6 abgewandten Unterseite sind am Geräteträger 7 hier zwei elektrische Anschlüsse 10 vorgesehen, über die ein hier nicht dargestelltes Leuchtmittel an den Geräteträger 7 angebaut und elektrisch angeschlossen werden kann.In the example shown the Fig. 2 the device carrier 7 on an upper side facing the carrier rail 6 has an electrical contact device 8 and at least one electronic module 9. At one side facing away from the mounting rail 6 underside two electrical connections 10 are provided on the equipment rack 7 here, via which a light bulb, not shown here, can be attached to the equipment carrier 7 and electrically connected.

Entsprechend Fig. 2 kann die Tragschiene 6 beispielsweise als U-förmiger Profilkörper ausgestaltet sein und dementsprechend einen U-förmigen Schienenquerschnitt 11 besitzen. Dieser Schienenquerschnitt 11 bzw. der Profilkörper der Tragschiene 6 umfasst zum Beispiel ein Basisprofil 12, von dem seitlich zwei Stegprofile 13 abstehen. Eine dem Basisprofil 12 gegenüberliegende Seite bildet eine offene Seite 14 des Schienenquerschnitts 11. In der Tragschiene 6, also in einem Innenraum 15 der Tragschiene 6 bzw. der Leuchte 2 kann ein Stromführungsprofil 16 angeordnet sein. Dieses kann sich z. B. bandförmig im Wesentlichen über die gesamte Länge der Tragschiene 6 erstrecken und kann die Stromversorgung sowie die elektrische Ansteuerung elektrischer Verbraucher der Leuchte 2 ermöglichen. Das Stromführungsprofil 16 ist dabei zweckmäßig im Bereich des Basisprofils 12 untergebracht. Es bildet bezüglich der Tragschiene 6 ein separates Bauteil und ist zweckmäßig flach.Corresponding Fig. 2 For example, the support rail 6 can be configured as a U-shaped profile body and accordingly have a U-shaped rail cross-section 11. This rail cross-section 11 and the profile body of the Support rail 6 includes, for example, a base profile 12, projecting from the side two web sections 13. A side facing the base profile 12 forms an open side 14 of the rail cross-section 11. In the support rail 6, that is to say in an interior 15 of the support rail 6 or the luminaire 2, a current-carrying profile 16 can be arranged. This can be z. B. extend band-shaped substantially over the entire length of the support rail 6 and can allow the power supply and the electrical control of electrical loads of the lamp 2. The current-carrying profile 16 is expediently accommodated in the region of the base profile 12. It forms a separate component with respect to the mounting rail 6 and is expediently flat.

Entsprechend den Fig. 3 bis 7 umfasst das Stromführungsprofil 16 einen Körper 17, der durch einen Trägerabschnitt 18 und mehrere Stegabschnitte 19 gebildet ist. Die Stegabschnitte 19 stehen dabei vom Trägerabschnitt 18 ab, und zwar vorzugsweise senkrecht. Die Stegabschnitte 19 sind am Trägerabschnitt 18 so angeordnet, dass sie zueinander parallel verlaufen und zueinander beabstandet sind, wodurch sie zwischen sich Lücken 20 ausbilden. Zweckmäßig ist der Körper 17 des Stromführungsprofils 16 aus einem elektrisch isolierenden Material hergestellt, zum Beispiel aus Kunststoff. Im Folgenden wird der Körper 17 auch als Kunststoffkörper 17 bezeichnet. Zweckmäßig ist dieser Kunststoffkörper 17 als Strangpressprofil oder Extrusionsprofil konzipiert. Im Beispiel weist das Stromführungsprofil 16 sechs Stegabschnitte 19 auf, nämlich zwei äußere Stegabschnitte 19 und vier mittlere oder innere Stegabschnitte 19. Dementsprechend sind fünf Lücken 20 vorhanden. Es ist klar, dass auch eine andere Anzahl an Stegabschnitten 19 und Lücken 20 vorgesehen sein kann.According to the Fig. 3 to 7 the current-carrying profile 16 comprises a body 17, which is formed by a support portion 18 and a plurality of web portions 19. The web portions 19 are from the support portion 18 from, preferably perpendicular. The web portions 19 are arranged on the support portion 18 so that they are parallel to each other and spaced from each other, whereby they form gaps 20 between them. Suitably, the body 17 of the current-carrying profile 16 is made of an electrically insulating material, for example of plastic. In the following, the body 17 is also referred to as a plastic body 17. Suitably, this plastic body 17 is designed as an extruded profile or extrusion profile. In the example, the current-carrying profile 16 has six web sections 19, namely two outer web sections 19 and four middle or inner web sections 19. Accordingly, there are five gaps 20. It is clear that a different number of web portions 19 and gaps 20 may be provided.

Zumindest einer der Stegabschnitte 19 trägt zumindest einen elektrischen Leiter 21 bzw. 22. Der jeweilige Leiter 21, 22 besteht in üblicher Weise aus Metall, z. B. Kupfer bzw. eine Kuperlegierung. Im Beispiel sind fünf elektrische Leiter 21, 22 vorgesehen. Erkennbar sind an den Stegabschnitten 19 weitere Aufnahmen 23 zum Aufnehmen weiterer elektrischer Leiter 21 vorgesehen. Dementsprechend ist auch eine andere Anzahl an Leitern 21, 22 denkbar. Die mit 21 bezeichneten elektrischen Leiter sind an den Stegabschnitten 19 so angeordnet, dass sie jeweils zu einer der Lücken 20 seitlich freistehend sind. Hierdurch sind diese elektrischen Leiter 21 innerhalb der jeweiligen Lücke 20 seitlich elektrisch kontaktierbar. Im Unterschied dazu ist der mit 22 bezeichnete elektrische Leiter, der an einem der äußeren Stegabschnitte 19 angeordnet ist, an einer von den Lücken 20 abgewandten Seite vorgesehen. Dieser Leiter wird im Folgenden auch als elektrischer Schutzleiter 22 bezeichnet. Während besagter Schutzleiter 22 durch die Schutzleitungsfunktion belegt ist, können die anderen Leiter 21 zur Stromversorgung und/oder zur Ansteuerung elektrischer Komponenten bzw. Geräte genutzt werden, die am jeweiligen Geräteträger 7 angeordnet sind.At least one of the web portions 19 carries at least one electrical conductor 21 and 22, respectively. The respective conductor 21, 22 consists in the usual way of metal, for. As copper or a copper alloy. In the example, five electrical conductors 21, 22 intended. Recognizable 19 further receptacles 23 are provided for receiving further electrical conductors 21 at the web portions. Accordingly, a different number of conductors 21, 22 is conceivable. The designated 21 electrical conductors are arranged on the web portions 19 so that they are each free laterally to one of the gaps 20. As a result, these electrical conductors 21 can be electrically contacted laterally within the respective gap 20. In contrast, the electrical conductor designated 22, which is arranged on one of the outer web portions 19, provided on a side facing away from the gaps 20 side. This conductor is also referred to below as the electrical protective conductor 22. While said protective conductor 22 is occupied by the protective line function, the other conductors 21 can be used for the power supply and / or for the control of electrical components or devices which are arranged on the respective equipment carrier 7.

Entsprechend den Fig. 4 bis 7 ist das Stromführungsprofil 16 zumindest an einem seiner Längsenden 24, die auch als axiale Enden 24 bezeichnet werden können, mit einer Endkappe 25 versehen. Es ist klar, dass zweckmäßig beide Längsenden 24 des Stromführungsprofils 16 jeweils mit einer solchen Endkappe 25 versehen sein können. Die jeweilige Endkappe 25 bildet bezüglich des Stromführungsprofils 16 ein separates Bauteil und ist entsprechend den Fig. 5 bis 7 im fertiggestellten Zustand des Stromführungsprofils 16 an dieses axial angebaut. Dabei ist die Endkappe 25 so konzipiert, dass sie den wenigstens einen elektrischen Leiter 21 axial abdeckt. Wie den Fig. 5 bis 7 entnehmbar ist, lassen sich die von der Endkappe 25 abgedeckten elektrischen Leiter 21 nicht mehr axial kontaktieren, wodurch ein effizienter Schutz realisiert wird.According to the Fig. 4 to 7 the current-carrying profile 16 is provided with an end cap 25 at least at one of its longitudinal ends 24, which may also be referred to as axial ends 24. It is clear that expediently both longitudinal ends 24 of the current-carrying profile 16 can each be provided with such an end cap 25. The respective end cap 25 forms with respect to the current-carrying profile 16 is a separate component and is corresponding to the Fig. 5 to 7 in the finished state of the current-carrying profile 16 attached to this axially. In this case, the end cap 25 is designed so that it covers the at least one electrical conductor 21 axially. Like that Fig. 5 to 7 is removed, the covered by the end cap 25 electrical conductors 21 can no longer contact axially, whereby an efficient protection is realized.

Die Endkappe 25 ist aus einem elektrisch isolierenden Werkstoff hergestellt. Bevorzugt wird dabei Kunststoff. Insbesondere handelt es sich bei der Endkappe 25 um ein Spritzgussteil.The end cap 25 is made of an electrically insulating material. Preference is given to plastic. In particular, the end cap 25 is an injection molded part.

Bemerkenswert ist nun, dass die Endkappe 19 nur diejenigen elektrischen Leiter 21 axial abdeckt, die zu einer der Lücken 20 freistehen. Im Unterschied dazu deckt die Endkappe 25 den elektrischen Schutzleiter 22, der an einem der außenliegenden Stegabschnitte 19 an der Außenseite 26 freistehend angeordnet ist, axial nicht ab. Hierdurch kann die Schutzleiterfunktion auch bei montierter Endkappe 25 gewährleistet werden. Da sich der Schutzleiter 22 nur an einem der außenliegenden Stegabschnitte 19 befindet, gibt es für den Fall, dass das Stromführungsprofil 16 an beiden Längsenden 24 jeweils mit einer solchen Endkappe 25 versehen sein soll, zwei verschiedene Ausführungsformen für die Endkappe 25, nämlich eine für das "linke" Längsende 24 und eine für das "rechte" Längsende 24. Die linke und die rechte Endkappe 25 sind zweckmäßig bezüglich einer Querschnittsebene spiegelsymmetrisch ausgestaltet.It is noteworthy that the end cap 19 only axially covers those electrical conductors 21 that are exposed to one of the gaps 20. In contrast, the end cap 25 covers the electrical protective conductor 22, which is arranged free-standing on one of the outer web portions 19 on the outer side 26, axially not. As a result, the protective conductor function can be ensured even when mounted end cap 25. Since the protective conductor 22 is located only on one of the outer web portions 19, there are two different embodiments for the end cap 25, namely one for the case that the current-carrying profile 16 is to be provided at both longitudinal ends 24 each with such an end cap 25 "left" longitudinal end 24 and one for the "right" longitudinal end 24. The left and the right end cap 25 are expedient designed with respect to a cross-sectional plane mirror symmetry.

Entsprechend den Fig. 8 bis 10 kann die Endkappe 25 für den jeweiligen von ihr axial abgedeckten elektrischen Leiter 21 einen Ausweichraum 27 aufweisen. Grundsätzlich kann bis auf den Schutzleiter 22 für alle Leiter 21 ein gemeinsamer Ausweichraum 27 vorgesehen sein. Bevorzugt wird jedoch die hier gezeigte Ausführung, die für jeden Leiter 21 einen separaten Ausweichraum 27 aufweist. Da die Endkappe 25 alle elektrischen Leiter 21 bis auf den Schutzleiter 22 abdeckt, sind im Beispiel zumindest vier Ausweichräume 27 vorhanden. Da das Stromführungsprofil 16 unter Berücksichtigung der noch freien Aufnahmen 23, von denen gemäß Fig. 3 sechs vorhanden sind, im Beispiel insgesamt elf Leiter 21 aufweisen kann, weist die Endkappe 25 zweckmäßig zumindest elf derartige Ausweichräume 27 auf, die je einem solchen elektrischen Leiter 21 zugeordnet sind. Dabei sind die einzelnen Ausweichräume 27 voneinander getrennt. Die Ausweichräume 27 fluchten im montierten Zustand axial zu dem jeweils zugeordneten elektrischen Leiter 21. Auf diese Weise kann der jeweilige Leiter 21 axial in den zugehörigen Ausweichraum 27 eintauchen, wenn er sich thermisch bedingt stärker ausdehnt als das übrige Stromführungsprofil 16, also wenn er sich stärker ausdehnt als der Kunststoffkörper 17. Entsprechend Fig. 8 besitzt die Endkappe 25 in einem Bereich 28, der im montierten Zustand axial zum Schutzleiter 22 fluchtet, eine Ausnehmung 29, wodurch kein Ausweichraum 27 für den Schutzleiter 22 vorgesehen ist.According to the Fig. 8 to 10 For example, the end cap 25 may have an escape space 27 for the respective electrical conductor 21 axially covered by it. In principle, a common escape space 27 can be provided for all conductors 21 except for the protective conductor 22. However, the embodiment shown here, which has a separate escape space 27 for each conductor 21, is preferred. Since the end cap 25 covers all electrical conductors 21 except for the protective conductor 22, at least four escape spaces 27 are present in the example. Since the current-carrying profile 16, taking into account the still free shots 23, of which according to Fig. 3 six are present, in the example may have a total of eleven conductors 21, the end cap 25 expediently at least eleven such alternative spaces 27, which are each associated with such an electrical conductor 21. The individual alternative spaces 27 are separated from each other. In the assembled state, the escape spaces 27 are aligned axially with the respective associated electrical conductor 21. In this way, the respective conductor 21 can dip axially into the associated escape space 27 if it becomes stronger thermally expands as the rest of the current guide profile 16, so if it expands more than the plastic body 17. Accordingly Fig. 8 has the end cap 25 in a region 28 which is aligned in the assembled state axially to the protective conductor 22, a recess 29, whereby no escape space 27 is provided for the protective conductor 22.

Entsprechend den Fig. 8 bis 10 ist die Endkappe 25 mit wenigstens einem Zapfen 30 ausgestattet. Im Beispiel sind genau fünf Zapfen 30 vorgesehen. Die Anzahl der Zapfen 30 entspricht zweckmäßig der Anzahl der Lücken 20. Zum Montieren der Endkappe 25 wird der jeweilige Zapfen 30 axial in eine der Lücken 20 eingesteckt. Dabei ist der jeweilige Zapfen 30 so auf die jeweilige Lücke 20 abgestimmt, dass sich durch den Steckvorgang eine kraftschlüssige bzw. reibschlüssige Fixierung des jeweiligen Zapfens 30 und somit der Endkappe 25 an den Stegabschnitten 19 und somit am Stromführungsprofil 16 ergibt.According to the Fig. 8 to 10 the end cap 25 is equipped with at least one pin 30. In the example, exactly five pins 30 are provided. The number of pins 30 expediently corresponds to the number of gaps 20. To mount the end cap 25, the respective pin 30 is inserted axially into one of the gaps 20. In this case, the respective pin 30 is matched to the respective gap 20 that results from the insertion process, a frictional or frictional fixation of the respective pin 30 and thus the end cap 25 on the web portions 19 and thus the current-carrying profile 16.

Wie sich insbesondere Fig. 9 entnehmen lässt, können benachbarte Zapfen 30 unterschiedliche axiale Längen aufweisen. Im gezeigten Beispiel sind drei kürzere Zapfen 30 und zwei längere Zapfen 30 vorgesehen, die sich abwechseln. Hierdurch kann die Montage der Endkappe 25 vereinfacht werden. Beim Einstecken der längeren Zapfen 30 in die zugehörigen Lücken 20 können die betroffenen Stegabschnitte 19 noch seitlich ausweichen, wodurch das Einstecken vereinfacht ist und außerdem eine Vorfixierung der Endkappe 25 am Stromführungsprofil 16 erzielbar ist. Gleichzeitig ergibt sich hierdurch bereits eine Führungswirkung, die das Einführen der verbleibenden kürzeren Zapfen 30 in die übrigen Lücken 20 vereinfacht.How, in particular Fig. 9 can be seen, adjacent pins 30 may have different axial lengths. In the example shown, three shorter pins 30 and two longer pins 30 are provided, which alternate. As a result, the assembly of the end cap 25 can be simplified. When inserting the longer pin 30 in the associated gaps 20, the affected web portions 19 can still escape laterally, whereby the insertion is simplified and also a prefixing of the end cap 25 on the current-carrying profile 16 can be achieved. At the same time, this already results in a guiding action which simplifies the insertion of the remaining shorter pins 30 into the remaining gaps 20.

Um die reibschlüssige bzw. kraftschlüssige Fixierung zwischen Endkappe 25 und Stromführungsprofil 16 zu begünstigen, kann der jeweilige Zapfen 30 entsprechend den Fig. 9 und 10 an seiner mit den Stegabschnitten 19 zusammenwirkenden Oberfläche eine reibungserhöhende Struktur 31 aufweisen. Im Beispiel ist diese reibungserhöhende Struktur 31 als Wiederhakenstruktur oder Dübelstruktur konzipiert. Es ist klar, dass auch andere reibungserhöhende Strukturen 21 realisierbar sind.In order to favor the frictional or non-positive fixation between the end cap 25 and current-carrying profile 16, the respective pin 30 can according to the FIGS. 9 and 10 at its cooperating with the web portions 19 Surface have a friction-increasing structure 31. In the example, this friction-increasing structure 31 is designed as a re-hook structure or dowel structure. It is clear that other friction-increasing structures 21 can be realized.

Um ein ordnungsgemäßes Positionieren der Endkappe 25 am Axialende 24 des Stromführungsprofils 16 zu vereinfachen, können die Stegabschnitte 19 gemäß Fig. 3 in Bereichen 32 zur jeweiligen Lücke 20 hin konkav geformt sein. In diesen Bereichen 32 dringt der jeweilige Zapfen 30 in die jeweilige Lücke 20 ein. Die konkave Formgebung ist im gezeigten Beispiel gestuft. Ebenso ist eine abgerundete Formgebung denkbar. Um die Fixierung zwischen Endkappe 25 und Stromführungsprofil 16 signifikant zu verbessern, kann es möglich sein, für die Herstellung der Endkappe 25 einen härteren Werkstoff zu verwenden als für den Körper 17 des Stromführungsprofils 16. Insbesondere kann daher die Endkappe 25 aus einem härteren Kunststoff hergestellt sein als der Kunststoffkörper 17. Hierdurch kann sich die reibungserhöhende Struktur 31 seitlich in die Stegabschnitte 19 eingraben, wodurch zusätzlich ein gewisser Formschluss realisiert wird.In order to facilitate a proper positioning of the end cap 25 at the axial end 24 of the current-carrying profile 16, the web portions 19 can according to Fig. 3 be concave in areas 32 to the respective gap 20. In these areas 32, the respective pin 30 penetrates into the respective gap 20. The concave shape is stepped in the example shown. Likewise, a rounded shape is conceivable. In order to significantly improve the fixation between the end cap 25 and the current-carrying profile 16, it may be possible to use a harder material for the production of the end cap 25 than for the body 17 of the current-carrying profile 16. In particular, therefore, the end cap 25 can be made of a harder plastic As a result, the friction-increasing structure 31 can dig itself laterally into the web sections 19, whereby in addition a certain positive connection is realized.

Die Zapfen 30 sind zweckmäßig als Hohlkörper ausgestaltet. Die Rückwand 34 ist geschlossen, wodurch auch die Ausweichräume 27 an einer vom Stromführungsprofil 16 abgewandten Seite verschlossen sind. Die Zapfen 30 weisen im Anschluss an ihre reibungserhöhende Struktur 31 einen zylindrischen Abschnitt 39 auf, von dem die Stege 33 abstehen. Die Zapfen 30 bzw. deren zylindrische Abschnitte 39 erstrecken sich bis zur Rückwand 34.The pins 30 are expediently designed as a hollow body. The rear wall 34 is closed, whereby the escape spaces 27 are closed at a side remote from the current-carrying profile 16 side. Following their friction-increasing structure 31, the pins 30 have a cylindrical section 39 from which the webs 33 protrude. The pins 30 and their cylindrical portions 39 extend to the rear wall 34th

Im Beispiel ist die Endkappe 25 entsprechend den Fig. 9 und 10 an jedem Zapfen 30 mit zwei Stegen 33 ausgestattet. Bezüglich des zugehörigen Zapfens 30 stehen die Stege 33 von diesem radial ab. Dabei liegen sich die beiden Stege 33 am jeweiligen Zapfen 30 diametral gegenüber. Ferner sind sie an der Endkappe 25 so positioniert, dass sie beim Montieren der Endkappe 25 in die dem zugehörigen Zapfen 30 zugeordnete Lücke 20 eintauchen. Die Stege 33 beginnen dabei axial versetzt zum freien Ende der Zapfen 30 und enden an einer Rückwand 34 der Endkappe 25. Außerdem sind die Stege 33 so dimensioniert, dass sie sich bis zu einer seitlichen Wand 35 der Endkappe 25 erstrecken. Dementsprechend trennen die Stege 33 innerhalb dieser seitlichen Wand 35 benachbarte Ausweichräume 27 voneinander. Gleichzeitig wird die Endkappe 25 durch diese Stege 33 sehr steif und formstabil.In the example, the end cap 25 is corresponding to the FIGS. 9 and 10 equipped with two webs 33 on each pin 30. With respect to the associated pin 30, the webs 33 are radially from this. In this case, the two webs 33 are diametrically opposed to the respective pin 30. Further, they are on the end cap 25th positioned so that they dive into the associated pin 30 associated gap 20 when mounting the end cap 25. The webs 33 thereby begin axially offset to the free end of the pin 30 and terminate at a rear wall 34 of the end cap 25. In addition, the webs 33 are dimensioned so that they extend to a lateral wall 35 of the end cap 25. Accordingly, the webs 33 separate within this lateral wall 35 adjacent escape spaces 27 from each other. At the same time the end cap 25 is very stiff and dimensionally stable by these webs 33.

Die Endkappe 25 kann außerdem mit einer Stoßkante 36 ausgestattet sein. Sie ist zweckmäßig durch eine dem Stromführungsprofil 16 zugewandte axiale Stirnseite der seitlichen Wand 35 gebildet. Im montierten Zustand kommt diese Stoßkante 36 an der der Endkappe 25 zugewandten axialen Stirnseite des Trägerabschnitts 18 des Stromführungsprofils 16 axial zur Anlage. Dabei kann die seitliche Wand 35 der Endkappe 25 im Wesentlichen die gleiche Dicke wie der Trägerabschnitt 18 des Stromführungsprofils 16 besitzen. Dementsprechend kann sich die Endkappe 25 im montierten Zustand flächenbündig an die Außenkontur des Stromführungsprofils 16 anschließen.The end cap 25 may also be equipped with a butt edge 36. It is expediently formed by a current-carrying profile 16 facing axial end face of the lateral wall 35. In the mounted state, this abutting edge 36 comes axially against the end cap 25 facing axial end face of the support portion 18 of the current-carrying profile 16. In this case, the lateral wall 35 of the end cap 25 may have substantially the same thickness as the carrier section 18 of the current-carrying profile 16. Accordingly, the end cap 25 in the mounted state can be flush with the outer contour of the current-carrying profile 16.

Die axiale Kontur der Endkappe 25 ist zweckmäßig an die axiale Kontur des Stromführungsprofils 16 bzw. des Körpers 17 angepasst. Beispielsweise besitzt das Stromführungsprofil 16 gemäß Fig. 3 an seinem Kunststoffkörper 17 an einem der außenliegenden Stegabschnitte 19 einen seitlich nach außen abstehenden Steg 37. Komplementär dazu ist auch die Endkappe 25 an ihrer seitlichen Wand 35 mit einem seitlich nach außen abstehenden Steg 38 versehen, der im montierten Zustand axial an den Steg 37 des Stromführungsprofils 16 anstößt. Dies ist zum Beispiel den Fig. 5 bis 7 entnehmbar.The axial contour of the end cap 25 is suitably adapted to the axial contour of the current-carrying profile 16 or of the body 17. For example, the current-carrying profile 16 has according to Fig. 3 At its plastic body 17 at one of the outer web portions 19 a laterally outwardly projecting web 37. Complementary to the end cap 25 is provided on its lateral wall 35 with a laterally outwardly projecting web 38 which in the assembled state axially to the web 37 of the Stromführungsprofils 16 abuts. This is for example the Fig. 5 to 7 removable.

Das Stromführungsprofil 16 besitzt im Beispiel der Fig. 3 an den seitlichen Enden des Tragabschnitts 18 angeformte Federstege 40, die im montierten Zustand des Stromführungsprofils 16 formschlüssig an einer entsprechenden Kontur der Tragschiene 6 bzw. des Basisprofils 12 einrasten.The current-carrying profile 16 has in the example of Fig. 3 formed on the lateral ends of the support portion 18 spring bars 40 which engage positively in the assembled state of the current-carrying profile 16 to a corresponding contour of the support rail 6 and der Basisprofils 12.
