Description

Die Erfindung betrifft eine lineare Stromverteileranordnung mit einer linearen Versorgungseinheit mit wenigstens einem Schutzleiter und einem Gehäusekörper, wobei die lineare Versorgungseinheit in dem Gehäusekörper gelagert ist.The invention relates to a linear power distribution arrangement with a linear supply unit with at least one protective conductor and a housing body, wherein the linear supply unit is mounted in the housing body.

Lineare Stromverteileranordnungen werden insbesondere für Beleuchtungssysteme in Gebäuden eingesetzt, um Leitungen zur Versorgung von Geräten mit Energie und/oder Signalen kostengünstig und optisch ansprechend zu verlegen. Unter Signalen wird dabei sowohl die Übertragung von allgemeinen Signalen, wie beispielsweise Steuersignalen, als auch die Übertragung von Daten, wie beispielsweise Mess- oder Informationsdaten, verstanden. Der Einbauort der Geräte kann flexibel entlang eines Gehäusekörpers der Stromverteileranordnung gewählt und leicht variiert werden. Die Geräte können damit auf einfache Weise mit einem Verbindungselement elektrisch leitend mit den Leitern einer linearen Versorgungseinheit an einem variabel festlegbaren Einbauort kontaktiert werden. Solche Stromverteileranordnungen haben den Vorteil, dass die Geräte sowohl elektrisch kontaktierend und auch zu gleich mechanisch an dem Gehäusekörper getragen werden.Linear power distribution arrangements are used in particular for lighting systems in buildings in order to lay cables for supplying devices with energy and/or signals in a cost-effective and visually appealing manner. Signals are understood to mean both the transmission of general signals, such as control signals, and the transmission of data, such as measurement or information data. The installation location of the devices can be flexibly selected along a housing body of the power distribution arrangement and easily varied. The devices can thus be easily electrically connected to the conductors of a linear supply unit at a variably definable installation location using a connecting element. Such power distribution arrangements have the advantage that the devices are both electrically contacted and mechanically supported on the housing body.

Zur Verteilung bzw. Weiterleitung der Energie oder Signale werden in den linearen Stromverteileranordnungen und so auch im Rahmen dieser Erfindung lineare Versorgungseinheiten verwendet, die in einem Gehäusekörper gelagert werden. Diese Versorgungseinheiten können dabei beispielsweise als Stromführungsprofile aber auch als Flachbandkabel ausgebildet sein. Die Stromführungsprofile sind dabei aus einem sich in Längsrichtung erstreckenden Grundkörper ausgebildet, der eine Anzahl von Kammern aufweist, in denen einzelne Leiter angeordnet sind. Diese Stromführungsprofile sind in der Regel starr ausgebildet und weisen herstellungsbedingt eine begrenzte Länge auf. Für längere Stromverteileranordnungen, wie sie beispielsweise in größeren Werks- oder Lagerhallen eingesetzt werden, sind daher üblicherweise mehrere Stromführungsprofile nötig, die dann über ein Verbindungselement sowohl mechanisch als auch elektrisch miteinander verbunden werden. Auch bei der Verwendung von Flachbandkabeln können je nach Länge des Flachbandkabels Verbindungselemente eingesetzt werden.To distribute or forward the energy or signals, linear supply units are used in the linear power distribution arrangements and thus also in the context of this invention, which are mounted in a housing body. These supply units can be designed, for example, as power guide profiles or as ribbon cables. The power guide profiles are made of a base body that extends in the longitudinal direction and has a number of chambers in which individual conductors are arranged. These power guide profiles are usually rigid and have a limited length due to the manufacturing process. For longer power distribution arrangements, such as those used in larger factories or warehouses, several power guide profiles are therefore usually required, which are then connected via a Connecting elements can be used to connect each other both mechanically and electrically. Connecting elements can also be used when using ribbon cables, depending on the length of the ribbon cable.

Da diese linearen Versorgungseinheiten meist über mehrere Meter verlegt werden, sind diese besonders anfällig für Längenausdehnungen des Materials aufgrund von hohen Temperaturen bzw. allgemein Temperaturschwankungen in der Umgebung. Dies führt in der Praxis regelmäßig dazu, dass die linearen Versorgungseinheiten bei der Ausdehnung einen Druck auf die Verbindungselemente oder Endkappen an den Enden der Versorgungseinheiten aufbauen, welcher entweder in einer Ausweichbewegung der Versorgungseinheiten quer zur linearen Erstreckungsrichtung oder in einer Verschiebung der Verbindungselemente bzw. Endkappen führt. Dies kann eine Kontaktierung der Endgeräte erschweren oder sogar unterbrechen. Umgekehrt kann es bei einer Verkürzung der Versorgungseinheiten durch Absenkung der Raumtemperatur dazu kommen, dass die Kontaktierung der Leiter der Versorgungseinheit mit den Verbindungselementen unterbrochen wird, sodass die nachfolgenden Versorgungseinheiten nicht mehr mit Signalen oder Strom versorgt werden können.Since these linear supply units are usually laid over several meters, they are particularly susceptible to linear expansion of the material due to high temperatures or general temperature fluctuations in the environment. In practice, this regularly leads to the linear supply units building up pressure on the connecting elements or end caps at the ends of the supply units when they expand, which either leads to an evasive movement of the supply units perpendicular to the linear extension direction or to a displacement of the connecting elements or end caps. This can make contact with the end devices more difficult or even interrupted. Conversely, if the supply units are shortened due to a drop in room temperature, the contact between the supply unit conductors and the connecting elements can be interrupted, meaning that the subsequent supply units can no longer be supplied with signals or power.

Erdungsbleche zur Verbindung eines Schutzleiters mit einem Gehäusekörper sind beispielsweise aus der Druckschrift EP 1 475 565 A2 und JP S57 85817 U bekannt.Earthing plates for connecting a protective conductor to a housing body are known, for example, from the publication EP 1 475 565 A2 and JP S57 85817 U known.

Die Aufgabe der vorliegenden Erfindung besteht daher darin eine lineare Stromverteileranordnung anzugeben, deren lineare Versorgungseinheit bestmöglich gegen Längenausdehnung durch Temperaturschwankungen geschützt bzw. im Gehäusekörper fixiert ist.The object of the present invention is therefore to provide a linear power distribution arrangement whose linear supply unit is protected as best as possible against linear expansion due to temperature fluctuations or is fixed in the housing body.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich durch die Merkmale der Unteransprüche.The object is achieved according to the invention by the characterizing features of independent claim 1. Advantageous embodiments result from the features of the subclaims.

Die Erfindung geht von der Überlegung aus, dass oben beschriebene lineare Versorgungseinheiten entsprechende Schutzleiter aufweisen, die elektrisch mit dem Gehäusekörper verbunden werden müssen, um den Schutzleiter zu erden. Da dies ohnehin über einen separaten Kontakt und somit ein separates Bauteil geschieht, wird im Rahmen der Erfindung dieser Kontakt dahingehend erweitert, dass er einerseits wie bisher die elektrische Verbindung zwischen dem Schutzleiter und dem Gehäusekörper herstellt, andererseits den Schutzleiter in der linearen Versorgungseinheit zentriert und drittens eine lineare Ausdehnung oder gar Verschiebung der Versorgungseinheiten verhindert. Das ursprünglich als reines Kontaktelement aufgebautes Bauteil, wird somit nun in einer Dreifachfunktion als Fixierungselement ausgebildet.The invention is based on the idea that the linear supply units described above have corresponding protective conductors that must be electrically connected to the housing body in order to ground the protective conductor. Since this is done via a separate contact and thus a separate component anyway, within the scope of the invention this contact is expanded so that on the one hand it creates the electrical connection between the protective conductor and the housing body as before, on the other hand it centers the protective conductor in the linear supply unit and thirdly it prevents linear expansion or even displacement of the supply units. The component that was originally designed as a pure contact element is now designed with a triple function as a fixing element.

Um die lineare Versorgungseinheit bestmöglich umgreifen zu können und so auch den Schutzleiter innerhalb der Versorgungseinheit zu zentrieren und zu fixieren, ist das Fixierungselement in bevorzugter Ausführung E-förmig ausgebildet. Dabei erstrecken sich die Halteschenkel an den Randbereichen des Fixierungselement, während der Kontaktierungssteg zwischen den Halteschenkel, insbesondere mittig zwischen diesen, angeordnet ist. Sowohl der Kontaktierungssteg als auch die Halteschenkel erstrecken sich in die gleiche Richtung, was insgesamt zu einem E-förmigen Querschnitt führt.In order to be able to grasp the linear supply unit as well as possible and thus also to center and fix the protective conductor within the supply unit, the fixing element is preferably designed in an E-shape. The holding legs extend along the edge areas of the fixing element, while the contacting web is arranged between the holding legs, in particular in the middle between them. Both the contacting web and the holding legs extend in the same direction, which leads to an overall E-shaped cross section.

Um die lineare Ausdehnung und Verschiebung der linearen Versorgungseinheit weiter einzuschränken, umfassen die Halteschenkel eine Anzahl von Lamellenelemente. Diese Lamellenelemente sind bevorzugt gegenüber der Ebene des jeweiligen Halteschenkels schräg ausgebildet, so dass diese schräg auf die lineare Versorgungseinheit und den Gehäusekörper wirkenden Lamellenelemente eine Kontaktkraft ausüben und dadurch die lineare Versorgungseinheit an einer Ausdehnung oder Verschiebung bei Temperaturschwankungen hindern.In order to further limit the linear expansion and displacement of the linear supply unit, the holding legs comprise a number of lamella elements. These lamella elements are preferably designed to be inclined relative to the plane of the respective holding leg, so that these lamella elements acting at an angle on the linear supply unit and the housing body exert a contact force and thereby prevent the linear supply unit from expanding or shifting in the event of temperature fluctuations.

Um diese Kräfte in beide Ausbreitungsrichtung gleichmäßig ausüben zu können, sind die Lamellenelemente in bevorzugter Ausgestaltung zumindest teilweise in verschiedene Richtungen orientiert.In order to be able to exert these forces evenly in both directions of propagation, the lamella elements are, in a preferred embodiment, at least partially oriented in different directions.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch die Weiterbildung eines Kontaktelements für den Schutzleiter zu einem Fixierungselement, mit einem einzelnen Bauteil und somit kostengünstig und platzsparend auch eine Fixierung des Schutzleiters und eine Längenausdehnung oder Verschiebung der linearen Versorgungseinheiten erzielt werden kann. Dabei müssen für diese Art der Kontaktierung und Fixierung die bestehenden Geometrien der linearen Versorgungseinheit und des Gehäusekörpers nicht gesondert angepasst werden, was das Fixierungselement sehr flexibel und leicht einsetzbar macht.The advantages achieved with the invention are in particular that by developing a contact element for the protective conductor into a fixing element, a fixing of the protective conductor and a length extension or displacement of the linear supply units can be achieved with a single component and thus cost-effectively and in a space-saving manner. The existing geometries of the linear supply unit and the housing body do not have to be specially adapted for this type of contacting and fixing, which makes the fixing element very flexible and easy to use.

Eine lineare Stromverteileranordnung 1 ist im Ausführungsbeispielnach der Fig. 1 gezeigt. Diese umfasst einen Gehäusekörper 2 mit einer Länge L in dem eine lineare Versorgungseinheit 4 angeordnet ist. Dazu umfasst der Gehäusekörper 2 einen entsprechend ausgeformten Aufnahmebereich 6 in dem die lineare Versorgungseinheit 4 an entsprechenden Kontaktzonen 5 eingeklemmt werden kann. Die lineare Versorgungseinheit 4 ist im Ausführungsbeispiel als Stromführungsprofil ausgebildet und umfasst eine Anzahl von Kammern 8 in denen Leiter 10 eingelegt werden können. Einer dieser Leiter 10, im Ausführungsbeispiel nach Fig. 1 der mittlere Leiter 10, ist als Schutzleiter 12 ausgebildet und muss im Betrieb mit dem Gehäusekörper 2 elektrisch verbunden bzw. geerdet werden.A linear power distribution arrangement 1 is in the embodiment according to the Fig.1 shown. This comprises a housing body 2 with a length L in which a linear supply unit 4 is arranged. For this purpose, the housing body 2 comprises a correspondingly shaped receiving area 6 in which the linear supply unit 4 can be clamped at corresponding contact zones 5. The linear supply unit 4 is designed in the embodiment as a current-carrying profile and comprises a number of chambers 8 in which conductors 10 can be inserted. One of these conductors 10, in the embodiment according to Fig.1 the middle conductor 10 is designed as a protective conductor 12 and must be electrically connected or earthed to the housing body 2 during operation.

Durch Temperaturschwankungen kann es allerdings passieren, dass sich die lineare Versorgungseinheit 4 ausdehnt bzw. zusammenzieht und auch bei mehreren Schwankungen innerhalb des Gehäusekörpers 2 verschiebt bzw. wandert. Für eine Fixierung der linearen Versorgungseinheit 4 und gleichzeitig einer Erdung des Schutzleiters 12 ist ein in Fig. 2 dargestelltes Fixierungselement 14 vorgesehen. Dieses Fixierungselement 14 umfasst einen Basisbereich 16 an dem sich auf einer Seite zwei Halteschenkel 18 und ein Kontaktierungssteg 20 erstrecken und somit einen E-förmigen Querschnitt bilden. Der Kontaktierungssteg 20 ist entsprechend der Position des Schutzleiters 12 mittig angeordnet. Er ist üblicherweise nicht über die gesamte Länge des Fixierungselementes in x Richtung ausgebildet, sondern erstreckt sich nur über einen Teilbereich. Kann sich aber auch im Einzelfall über die gesamte Länge erstrecken.However, due to temperature fluctuations, the linear supply unit 4 may expand or contract and even with several Fluctuations within the housing body 2. For fixing the linear supply unit 4 and at the same time earthing the protective conductor 12, a Fig.2 shown fixing element 14 is provided. This fixing element 14 comprises a base area 16 on which two holding legs 18 and a contacting web 20 extend on one side and thus form an E-shaped cross section. The contacting web 20 is arranged centrally according to the position of the protective conductor 12. It is usually not formed over the entire length of the fixing element in the x direction, but only extends over a partial area. However, it can also extend over the entire length in individual cases.

Die Halteschenkel 18 sind in den Randbereichen des Basisbereichs 16 angeformt und erstrecken sich in die gleiche Richtung wie der Kontaktierungssteg 20. Am vom Basisbereich 18 abgewandten Ende der Halteschenkel 18 ist eine Lamellenstruktur vorgesehen mit einer Anzahl vom Lamellenelementen 22, die leicht aus der Ebene 24 des Halteschenkels 18 heraus verdreht angeordnet sind. Dies ist im Ausführungsbeispiel nach Fig. 3 noch einmal verdeutlicht dargestellt. Fig. 3 zeigt ein Halteschenkel 18 von unten, wodurch sichtbar ist, dass sich die Lamellenelemente 22 aus der Ebene 24 des Halteschenkel 18 herausdrehen. In diesem Ausführungsbeispiel sind dabei vier Lamellenelemente 22a gegen den Uhrzeigersinn herausgebogen und vier Lamellenelemente 22b im Uhrzeigersinn verdreht. Je nach Einsatzzweck und Anwendungsfall kann aber auch eine alternierende Anordnung bevorzugt werden, wie auch der Winkel der Verdrehung entsprechend den Anforderungen verändert werden kann.The holding legs 18 are formed in the edge areas of the base area 16 and extend in the same direction as the contacting web 20. At the end of the holding legs 18 facing away from the base area 18, a lamellar structure is provided with a number of lamellar elements 22 which are arranged slightly twisted out of the plane 24 of the holding leg 18. This is the case in the embodiment according to Fig.3 once again made clearer. Fig.3 shows a holding leg 18 from below, whereby it is visible that the slat elements 22 rotate out of the plane 24 of the holding leg 18. In this embodiment, four slat elements 22a are bent out anti-clockwise and four slat elements 22b are rotated clockwise. Depending on the intended use and application, an alternating arrangement may also be preferred, and the angle of rotation can also be changed according to requirements.

Das Fixierungselement 14 ist im Ausführungsbeispiel nach Fig. 4 im Einsatz gezeigt. Das Fixierungselement 14 wird dabei so eingesetzt, dass der Kontaktierungssteg 20 den Schutzleiter 12 berührt und somit kontaktiert. Der Basisbereich 16 des Fixierungselementes 14 ist dabei so ausgebildet, dass die Halteschenkel 18 die lineare Versorgungseinheit 4 umgreifen und in die Kontaktzone 5 eingreifen. Durch dieses Eingreifen wird die lineare Versorgungseinheit 4 weiter im Aufnahmebereich 6 des Gehäusekörpers 2 gehalten und fixiert. Da sowohl der Kontaktierungssteg 20 als auch der Basisbereich 16 und die Halteschenkel 18 elektrisch leitend ausgebildet sind, wird hierbei eine elektrische Verbindung vom Schutzleiter 12 zum Gehäusekörper 2 hergestellt, wodurch der Schutzleiter 12 geerdet wird. Weiterhin wird der Schutzleiter 12 durch diese Anordnung in der Mitte fixiert.The fixing element 14 is in the embodiment according to Fig.4 shown in use. The fixing element 14 is inserted in such a way that the contacting web 20 touches the protective conductor 12 and thus makes contact. The base area 16 of the fixing element 14 is designed in such a way that the holding legs 18 encompass the linear supply unit 4 and engage in the contact zone 5. This engagement further holds and fixes the linear supply unit 4 in the receiving area 6 of the housing body 2. Since both the contacting web 20 and the base area 16 and the holding legs 18 are designed to be electrically conductive, an electrical connection is made from the protective conductor 12 to the housing body 2, whereby the protective conductor 12 is earthed. Furthermore, the protective conductor 12 is fixed in the middle by this arrangement.

Die Lamellenelemente 22 sorgen darüber hinaus durch ihre entsprechende Ausrichtung dafür, dass eine lineare Ausdehnung und Verschiebung der linearen Versorgungseinheit 4 vermieden wird und diese somit in ihrer Position fixiert wird. Weiterhin können sich die Lamellenelemente 22 in eine mögliche Pulverbeschichtung oder Isolierung des Gehäusekörpers 2eindringen und so direkt metallischen Grundkörper des Gehäusekörpers 2 kontaktieren.Furthermore, the slat elements 22 ensure, through their appropriate alignment, that a linear expansion and displacement of the linear supply unit 4 is avoided and this is thus fixed in its position. Furthermore, the slat elements 22 can penetrate into a possible powder coating or insulation of the housing body 2 and thus directly contact the metallic base body of the housing body 2.

In den Ausführungsbeispielen nach der Fig. 5 und Fig. 6 sind alternative, einstückige Fixierungselemente 14 aus einem Blechteil gezeigt. Oben ist jeweils der Grundschnitt mit entsprechenden Falzlinien 26 dargestellt und in der unteren Abbildung das zugehörige gefalzte und einsatzbereite Fixierungselement 14. Durch diese einstückige Ausbildung des Fixierungselements 14 kann dieses besonders leicht und kostengünstig an bestehende lineare Stromführungsprofile 1 angepasst bzw. für diese gefertigt werden.In the examples according to the Fig. 5 and Fig. 6 alternative, one-piece fixing elements 14 made from a sheet metal part are shown. The basic section with corresponding fold lines 26 is shown at the top and the corresponding folded and ready-to-use fixing element 14 is shown in the lower figure. Due to this one-piece design of the fixing element 14, it can be adapted to existing linear current-carrying profiles 1 or manufactured for them particularly easily and inexpensively.

Sollte im Einzelfall eine Erdung des Schutzleiters bereits auf anderem Wege geschehen sein und nur noch eine Fixierung der linearen Versorgungseinheit im Gehäusekörper gewünscht werden, können die Halteschenkel in allen hier erwähnten Ausführungsbeispielen auch einzeln verwendet werden und in die Kontaktzone des Gehäusekörpers und der linearen Versorgungseinheit eingeschoben werden. In diesem Fall ist der Basisbereich und der Kontaktierungssteg nicht mehr nötig und die Halteschenkel als einfache Bleche mit gegebenenfalls Lamellenelementen wie beispielsweise in Fig. 3 dargestellt ausgebildet.If in an individual case the protective conductor has already been earthed in another way and only the linear supply unit needs to be fixed in the housing body, the retaining legs can also be used individually in all the embodiments mentioned here and inserted into the contact zone of the housing body and the linear supply unit. In this case, the base area and the contacting bar are no longer required and the retaining legs can be designed as simple metal sheets with, if necessary, lamella elements, such as in Fig.3 shown.
