Description

Die Erfindung betrifft einen Abgriff für eine lineare Stromverteileranordnung, wobei der Abgriff eine Leiterplatte und eine Anzahl von Kontaktelementen umfasst.The invention relates to a tap for a linear power distribution arrangement, the tap comprising a circuit board and a number of contact elements.

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 and easily varied along a housing body of the power distribution arrangement. The devices can thus be contacted in an electrically conductive manner using a connecting element with the conductors of a linear supply unit at a variably definable installation location. Such power distribution arrangements have the advantage that the devices are carried on the housing body both in an electrically contacting manner and also mechanically.

Zur Verteilung bzw. Weiterleitung der Energie oder Signale werden in den linearen Stromverteileranordnungen meist 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 aus einem sich in Längsrichtung erstreckenden Grundkörper mit einem Kontaktierungsbereich 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 usually used in the linear power distribution arrangements, which are stored in a housing body. These supply units can be designed, for example, as current-carrying profiles but also as ribbon cables. The current-carrying profiles are formed from a base body extending in the longitudinal direction with a contacting area which has a number of chambers in which individual conductors are arranged. These current-carrying profiles are generally 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 supply profiles are usually required, which are then connected via a connecting element be connected to each other both mechanically and electrically. Depending on the length of the ribbon cable, connecting elements can also be used when using ribbon cables.

Die Kontaktierung der Endgeräte mit den Leitern der linearen Versorgungseinheiten erfolgt dabei üblicherweise über einen Abgriff, der eine Anzahl von Kontaktelementen umfasst. Diese Kontaktelemente greifen in die Kammern ein und kontaktieren die entsprechenden Leitern, wodurch die Signale oder die Energie von den Leitern über die Abgriffe an die Endgeräte geleitet werden können. Problematisch bei dieser Art der Ausgestaltung ist allerdings, dass die Abgriffe bislang aus einer Anzahl einzelner Kontaktelemente aufgebaut sind, die jeweils als ein eigenes Bauteil ausgebildet sind, dass nicht nur einzeln in den Abgriff integriert, sondern auch einzeln verdrahtet und angeschlossen werden muss. Dies führt in der Herstellung der Abgriffe zu einem erheblichen Materialmehraufwand, komplizierten und fehleranfälligen Arbeitsschritten bei dem Anschluss der Kontaktelemente und einem erhöhten Platzbedarf, weil auch die Verkabelung der Kontaktelemente in den Abgriff integriert werden muss.The terminal devices are contacted with the conductors of the linear supply units usually via a tap that includes a number of contact elements. These contact elements engage in the chambers and contact the corresponding conductors, whereby the signals or energy from the conductors can be conducted to the terminal devices via the taps. The problem with this type of design, however, is that the taps have so far been constructed from a number of individual contact elements, each of which is designed as a separate component that not only has to be individually integrated into the tap, but also has to be wired and connected individually. This leads to considerable additional material expenditure in the production of the taps, complicated and error-prone work steps when connecting the contact elements and an increased space requirement because the wiring of the contact elements also has to be integrated into the tap.

Darüber hinaus werden die Kontaktelemente im Abgriff aufgrund der oben erwähnten Komplexität und des Aufwandes üblicherweise einmalig eingebaut und angeschlossen, sodass eine spätere Positionsänderung kaum bzw. nur unter erheblichen Arbeitsmehraufwand möglich ist.In addition, due to the above-mentioned complexity and effort, the contact elements in the tap are usually installed and connected once, so that a later change in position is hardly possible or only possible with considerable additional effort.

Abgriffe mit Leiterplatten sind insbesondere aus den Druckschriften EP 3 403 532 A1 und EP 3 539 425 A1 bekannt.Taps with circuit boards are particularly from the publications EP 3 403 532 A1 and EP 3 539 425 A1 known.

Der Erfindung liegt daher die Aufgabe zu Grunde ein System, insbesondere einen Abgriff, zum Abgreifen der Signale und/oder der Energie einer linearen Stromverteileranordnung anzugeben, das besonders kompakt, kostengünstig und leicht herstellbar ist und in dem die Position der Kontaktelemente besonders leicht verändert werden kann.The invention is therefore based on the object of specifying a system, in particular a tap, for tapping the signals and / or the energy of a linear power distribution arrangement, which is particularly compact, inexpensive and easy to manufacture and in which the position of the contact elements can be changed particularly easily .

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved according to the invention by the characterizing features of claim 1.

Die Erfindung geht von der Überlegung aus, dass eine besonders kompakte Bauweise und schnelle und einfache Herstellung dann erreicht werden kann, wenn auf den Anschluss und die Verdrahtung jedes einzelnen Kontaktelements verzichtet werden könnte. Dies könnte dann der Fall sein, wenn der Abgriff bereits vordefinierte Anschlüsse oder Kontaktplätze für die Kontaktelemente bereitstellt, die bereits in einem vorgelagerten Arbeitsschritt und bevorzugt automatisiert angeschlossen sind. Dabei wurde erkannt, dass dies dann erreicht werden kann, wenn für die Verdrahtung der Kontaktelemente Leiterbahnen einer Leiterplatte verwendet werden und die Kontaktelemente an vorgegebenen Positionen auf der Leiterplatte angeordnet werden. Hierbei können die Kontaktelemente an diesen Positionen aufgelötet, aufgesteckt oder angeschraubt werden.The invention is based on the idea that a particularly compact design and quick and simple production can be achieved if the connection and wiring of each individual contact element could be dispensed with. This could be the case if the tap already provides predefined connections or contact locations for the contact elements, which are already connected in a previous work step and preferably automatically. It was recognized that this can be achieved if conductor tracks of a circuit board are used for wiring the contact elements and the contact elements are arranged at predetermined positions on the circuit board. The contact elements can be soldered, plugged or screwed on at these positions.

Für ein besonders leichtes Aufstecken der Kontaktelemente sind die Strombrücken auf der Leiterplatte angeordnet, auf die die Kontaktelemente aufgesteckt werden. Dabei sind diese Kontaktelemente auf den Strombrücken und entlang dieser bewegbar ausgeführt, sodass die Position der Kontaktelemente entlang dieser Strombrücken besonders leicht variiert werden kann. Die Strombrücken sind dabei selbstverständlich nicht nur für die Halterung der Kontaktelemente ausgebildet, sondern können auch die Signale aufnehmen und an die Leiterbahnen weiterleiten. Die Strombrücken werden in bevorzugter Ausgestaltung auf die Leiterplatte gelötet, gesteckt oder verschraubt.To make it particularly easy to plug in the contact elements, the current bridges are arranged on the circuit board onto which the contact elements are plugged. These contact elements are designed to be movable on the current bridges and along them, so that the position of the contact elements along these current bridges can be varied particularly easily. The current bridges are of course not only designed to hold the contact elements, but can also receive the signals and forward them to the conductor tracks. In a preferred embodiment, the current bridges are soldered, plugged or screwed onto the circuit board.

Während die Strombrücken eine Verschieben der Kontaktelemente in der Ebene der Leiterplatte ermöglichen, ist es für eine ausreichend hohe Kontaktkraft wünschenswert, wenn die Kontaktelemente auch senkrecht zur Ebene der Leiterplatte, also in Richtung der Leiter der linearen Versorgungseinheiten, verschoben werden kann. Daher umfassen die Kontaktelemente Federelemente, die eine Federkraft senkrecht zur Ebene der Leiterplatte und in Richtung der Leiter der linearen Versorgungseinheiten erzeugen und so die Kontaktelemente gegen die Leiter drücken. Dadurch kann stets eine ausreichend hohe Kontaktkraft bereitgestellt werden. Die Federelemente sind in den Kontaktelementen bevorzugt derart angeordnet, dass sie sich an den Strombrücken abstützen und somit eine Federkraft in Richtung der Leiter erzeugen.While the current bridges enable the contact elements to be moved in the plane of the circuit board, it is desirable for a sufficiently high contact force if the contact elements can also be moved perpendicular to the plane of the circuit board, i.e. in the direction of the conductors of the linear supply units. Therefore, the contact elements include spring elements that generate a spring force perpendicular to the plane of the circuit board and in the direction of the conductors of the linear supply units and thus press the contact elements against the conductors. This means that a sufficiently high contact force can always be provided. The spring elements are preferably arranged in the contact elements in such a way that they are supported on the current bridges and thus generate a spring force in the direction of the conductors.

Für einen besonders einfachen Anschluss der Endgeräte an den Abgriff umfasst die Leiterplatte mindestens eine Buchse, die über Leiterbahnen elektrisch, d.h. energie- und/oder signaltechnisch, mit den Kontaktelementen verbunden ist. So können die Endgeräte an einer oder mehreren zentralen Stellen mit dem Abgriff verbunden werden und eine Einzelverdrahtung jedes Kontaktelements mit einem Endgerät fällt aus.For a particularly simple connection of the terminal devices to the tap, the circuit board comprises at least one socket, which is electrically connected to the contact elements via conductor tracks, i.e. in terms of energy and/or signaling. In this way, the terminal devices can be connected to the tap at one or more central locations and individual wiring of each contact element to a terminal device is not necessary.

Im Betrieb der linearen Stromverteileranordnung kann es wünschenswert sein, dass die vom Abgriff aufgenommenen Signale oder auch die Energie bereits vor Weiterleitung an die Endgeräte entsprechend verarbeitet werden. Dazu zählt insbesondere das Filtern gewisser Daten und Logikprüfungen bzw. Fallbearbeitungen bei Eintreffen gewisser Signale. Daher umfasst die Leiterplatte in vorteilhafter Ausführung elektronische Bauteile auf der Leiterplatte, um die eintreffende Energie oder die Signale zu verarbeiten. Diese elektronischen Bauteile können dabei insbesondere Chips oder Logikeinheiten sein.During operation of the linear power distribution arrangement, it may be desirable for the signals picked up by the tap or the energy to be processed accordingly before being forwarded to the terminal devices. This includes in particular the filtering of certain data and logic checks or case processing when certain signals arrive. Therefore, in an advantageous embodiment, the circuit board comprises electronic components on the circuit board in order to process the incoming energy or the signals. These electronic components can in particular be chips or logic units.

Für einen erhöhten Schutz kann mindestens eine Strombrücke eine Erdleitung umfassen, die bevorzugt mit dem Gehäuse der Stromverteileranordnung verbunden ist.For increased protection, at least one current bridge can comprise a ground line, which is preferably connected to the housing of the power distribution arrangement.

Um die Leiterbahnen, die elektrischen Bauteile und auch die Strombrücken, insgesamt also die Leiterplatte selbst, zu schützen, umfasst der Abgriff eine Schutzabdeckung. Diese Schutzabdeckung weist dabei eine Anzahl von Öffnungen auf, durch die die Kontaktelemente durchgreifen können. Die Öffnungen sind dabei so ausgeführt, dass die Kontaktelemente weiter entlang der Strombrücken verschoben werden können, bilden also den Verlauf der Strombrücken nach. Die Schutzabdeckung wird dabei nach dem Aufstecken der Kontaktelemente auf die Strombrücken der Leiterplatte aufgesteckt und an ihr befestigt. Im Falle der federnd gelagerten Kontaktelemente, kann die Schutzabdeckung auch als Stopper dienen. Dabei umfasst das Kontaktelement einen Anschlag der breiter ausgeführt ist als die Breite der Öffnungen, wodurch die Kontaktelemente nur bis zu einer gewissen Tiefe durch die Öffnungen durchgreifen können.In order to protect the conductor tracks, the electrical components and also the current bridges, i.e. the circuit board itself, the tap includes a protective cover. This protective cover has a number of openings through which the contact elements can pass. The openings are designed in such a way that the contact elements can be moved further along the current bridges, i.e. they simulate the course of the current bridges. The protective cover is installed after the contact elements have been plugged onto the current bridges plugged into the circuit board and attached to it. In the case of spring-mounted contact elements, the protective cover can also serve as a stopper. The contact element includes a stop that is wider than the width of the openings, whereby the contact elements can only reach through the openings to a certain depth.

Eine besonders kompakte Bauweise kann insbesondere dann erzielt werden, wenn die Kontaktelemente und Strombrücken sich eine Leiterplatte mit den Steuereinheiten der Endgeräte, insbesondere der Treiber für Leuchtmittel, teilen. Hierbei würde dann die zusätzliche Verdrahtung oder der Zusätzliche Anschluss der Steuereinheiten an den Abgriff entfallen, da über die gemeinsam genutzte Leiterplatte und vorhandenen Leiterbahnen alle Bauteile miteinander elektrisch und signaltechnisch verbunden werden können. Daher ist in besonders bevorzugter Ausgestaltung die Treiberleiterplatte, also die Leiterplatte der Steuereinheit eines Endgerätes, gleichzeitig auch die Leiterplatte für einen Abgriff auf dem Kontaktelemente angeordnet sind.A particularly compact design can be achieved in particular if the contact elements and current bridges share a circuit board with the control units of the end devices, in particular the drivers for lighting devices. This would then eliminate the need for additional wiring or additional connection of the control units to the tap, since all components can be connected to one another electrically and in terms of signals via the shared circuit board and existing conductor tracks. Therefore, in a particularly preferred embodiment, the driver circuit board, i.e. the circuit board of the control unit of a terminal, is also arranged at the same time as the circuit board for a tap on which contact elements are arranged.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch die Anordnung der Kontaktelemente auf einer Leiterplatte eine besonders kompakte und einfache Bauweise der Abgriffe ermöglicht wird. Es entfallen die Aufwändigen und platzkostenden Verdrahtungen der einzelnen Kontaktelemente mit den Endgeräten, da diese durch vorgefertigte Leiterbahnen ersetzt werden. Insbesondere kann dabei die ohnehin bereits vorhandene Leiterplatte einer Steuereinheit für die Endgeräte, insbesondere eines Treibers für Leuchtmittel, verwendet werden, wodurch weiterer Platz und weitere Kosten eingespart werden können. Durch die Verwendung einer Leiterplatte können auf einfachste Art und Weise weitere elektrische Bauteile zur Bearbeitung der eintreffenden Energie oder Signale im System integriert werden, was vielfältige Möglichkeiten bietet.The advantages achieved by the invention are, in particular, that the arrangement of the contact elements on a circuit board enables a particularly compact and simple design of the taps. The complex and space-consuming wiring of the individual contact elements to the end devices is no longer necessary, as these are replaced by prefabricated conductor tracks. In particular, the already existing circuit board of a control unit for the end devices, in particular a driver for lighting devices, can be used, whereby further space and additional costs can be saved. By using a circuit board, additional electrical components for processing the incoming energy or signals can be easily integrated into the system, which offers a wide range of possibilities.

Ein Ausführungsbeispiel eines Abgriffs 1 ist Fig. 1 dargestellt. Der Abgriff 1 umfasst dabei eine Leiterplatte 2 auf der eine Vielzahl von Elementen angeordnet sind. Dazu zählen im Wesentlichen eine Anzahl von Strombrücken 4, die auf der Leiterplatte 2 verlötet oder gesteckt sind und mit nicht dargestellten Leiterbahnen elektrisch oder signaltechnisch verbunden werden. Diese Strombrücken 4 dienen dabei als Steckplätze für die Kontaktelemente 6 und stellen ebenfalls eine elektrische oder signaltechnische Verbindung zwischen den Leiterbahnen und den Kontaktelementen 6 her. Die Strombrücken 4 sind dabei senkrecht zur Leiterplattenebene angeordnet und erstrecken sich in Richtung der zu kontaktierenden Leiter. Für eine zuverlässige Kontaktierung der Leiter durch die Kontaktelemente 6 umfassen diese über nicht dargestellte Federelemente. Diese Federelemente sind innerhalb der Kontaktelemente 6 angeordnet und stützen sich auf den Strombrücken 4, bzw. in der Regel auf dem oberen, d.h. der Leiterplatte 2 abgewandten Rand der Strombrücken 4 ab und erzeugen eine Federkraft, die die Kontaktelemente 6 in Richtung der Leiter drückt. Dies bedeutet, dass die Federelemente gezielt dazu ausgebildet sind den Kontakt zwischen den Kontaktelementen 6 und den Leitern zu sichern und nicht, um eine Kontaktierung der Kontaktelemente 6 auf den Strombrücken 4 zu ermöglichen. Aus diesem Grund sind die Federelemente auch im Wesentlichen nicht stromführend ausgebildet. Die Stromführung zwischen den Kontaktelementen 6 und den Strombrücken 4 wird bevorzugt durch einen Gabelkontakt ausgeführt.An embodiment of a tap 1 is Fig. 1 shown. The tap 1 includes a circuit board 2 on which a large number of elements are arranged. These essentially include a number of current bridges 4, which are soldered or plugged onto the circuit board 2 and are connected electrically or for signaling purposes to conductor tracks (not shown). These current bridges 4 serve as slots for the contact elements 6 and also establish an electrical or signaling connection between the conductor tracks and the contact elements 6. The current bridges 4 are arranged perpendicular to the circuit board plane and extend in the direction of the conductors to be contacted. For reliable contacting of the conductors by the contact elements 6, they include spring elements (not shown). These spring elements are arranged within the contact elements 6 and are supported on the current bridges 4, or generally on the upper edge of the current bridges 4, ie the edge facing away from the circuit board 2, and generate a spring force which presses the contact elements 6 in the direction of the conductors. This means that the spring elements are specifically designed to secure the contact between the contact elements 6 and the conductors and not to enable contacting of the contact elements 6 on the current bridges 4. For this reason, the spring elements are essentially not designed to carry current. The current conduction between the contact elements 6 and the current bridges 4 is preferably carried out by a fork contact.

Wie dargestellt, sind die Strombrücken 4 verbreitert ausgeführt, sodass die Kontaktelemente 6 entlang der Strombrücken 4 verschoben werden können, um so unterschiedliche Leiter einer linearen Versorgungseinheit kontaktieren zu können.As shown, the current bridges 4 are designed to be widened, so that the contact elements 6 can be moved along the current bridges 4 in order to be able to contact different conductors of a linear supply unit.

Weiterhin umfasst die Leiterplatte 2 eine Anzahl von Buchsen 8, die ebenfalls elektrisch und signaltechnisch mit den Leiterbahnen verbunden sind somit direkt mit den Kontaktelementen 6. In diese Buchsen 8 können Stecker oder Einzelleiter der Endgeräte oder der Steuerelemente für Endgeräte eingesteckt werden, sodass ein besonders einfacher Anschluss des Abgriffs 1 möglich ist.Furthermore, the circuit board 2 comprises a number of sockets 8, which are also electrically and signally connected to the conductor tracks and thus directly to the contact elements 6. Plugs or individual conductors of the terminal devices or the control elements for terminal devices can be inserted into these sockets 8, so that a particularly simple Connection of tap 1 is possible.

Im Ausführungsbeispiel nach der Fig. 2 ist die Leiterplatte 2 in ein Gehäuse 10 gefasst und mit einer Schutzabdeckung 12 versehen. Diese Schutzabdeckung 12 umfasst dabei eine Anzahl von Öffnungen 14, die in der Position und Dimensionierung an die Strombrücken 4 auf der Leiterplatte 2 angepasst sind. Durch diese Öffnungen 14 können die Kontaktelemente 6 durchgreifen. Um ein herausfallen oder abrutschen der Kontaktelemente 6 durch die Öffnungen 14 und von den Strombrücken 4 zu verhindern, umfassen die Kontaktelemente 6 einen Anschlag 16, der im Ausführungsbeispiel nach der Fig. 1 sichtbar ist. Durch die Abstimmung der Öffnungen 14 an die Strombrücken 4 können die Kontaktelemente 6 auch bei aufgesetzter Schutzabdeckung 12 weiter entlang der Strombrücken 4 verschoben werden, ohne von diesen abzurutschen.In the exemplary embodiment according to the Fig. 2 the circuit board 2 is housed in a housing 10 and provided with a protective cover 12. This protective cover 12 includes a number of openings 14, the position and dimensions of which are adapted to the current bridges 4 on the circuit board 2. The contact elements 6 can pass through these openings 14. In order to prevent the contact elements 6 from falling out or slipping through the openings 14 and from the current bridges 4, the contact elements 6 include a stop 16, which in the exemplary embodiment according to Fig. 1 is visible. By matching the openings 14 to the current bridges 4, the contact elements 6 can be moved further along the current bridges 4 without slipping off them, even when the protective cover 12 is in place.

Für einen sicheren Halt der Schutzabdeckung 12 an dem Gehäuse 10 umfassen beide Elemente entsprechende Halterungen 18 beispielsweise in Form eines Rasthakens.For a secure hold of the protective cover 12 on the housing 10, both elements include corresponding holders 18, for example in the form of a locking hook.

Im Ausführungsbeispiel nach Fig. 3 ist ein solcher Abgriff 1 im Einsatz, das heißt, in der Kontaktierung mit einer linearen Versorgungseinheit 20 dargestellt.In the exemplary embodiment according to Fig. 3 Such a tap 1 is shown in use, that is, in contact with a linear supply unit 20.

Eine solche lineare Versorgungseinheit 1 wird üblicherweise in nicht dargestellten linearen Stromverteileranordnungen verwendet. Diese lineare Stromverteileranordnungen umfassen dabei regelmäßig einen Gehäusekörper, der einen Bodenabschnitt und zwei Seitenwandabschnitte aufweist, die sich jeweils von den gegenüberliegenden Randbereichen des Bodenabschnitts wegerstrecken und im Wesentlichen parallel zueinander und senkrecht zum Bodenabschnitt ausgebildet sind. Diese Gehäusekörper werden dabei an der Decke eines Gebäudes befestigt und umfassen eine Halterung zur Aufnahme einer linearen Versorgungseinheit 20.Such a linear supply unit 1 is usually used in linear power distribution arrangements, not shown. These linear power distribution arrangements regularly include a housing body which has a base section and two side wall sections, which each extend away from the opposite edge regions of the base section and are designed essentially parallel to one another and perpendicular to the base section. These housing bodies are attached to the ceiling of a building and include a holder for receiving a linear supply unit 20.

Ein ebenfalls nicht dargestellter Einspeiser leitet dann Strom und/oder Signale in die linearen Versorgungseinheiten 20.A feeder, also not shown, then directs current and/or signals into the linear supply units 20.

Die lineare Versorgungseinheit 20 ist in Fig. 3 Stromführungsprofil ausgebildet und umfasst einen Grundkörper 22 aus einem Basismaterial mit einer Anzahl von nebeneinander angeordneten Kammern 24 zur Aufnahme von Leitern 26. Neben der in Fig. 3 dargestellten Anordnung der Kammern nebeneinander und in einer Ebene, ist auch die Anordnung der Kammern in mehreren Ebenen bzw. versetzt zueinander denkbar.The linear supply unit 20 is in Fig. 3 Current-carrying profile is formed and comprises a base body 22 made of a base material with a number of chambers 24 arranged next to one another for receiving conductors 26. In addition to the one in Fig. 3 As shown in the arrangement of the chambers next to each other and in one plane, the arrangement of the chambers in several planes or offset from one another is also conceivable.

Der Abgriff 1 greift dabei im Ausführungsbeispiel nach Fig. 3 mit seinen Kontaktelementen 6 in die Kammern 24 der linearen Versorgungseinheit 20 ein und kontaktiert die Leiter 26. Über die Kontaktelemente 6, die Strombrücken 4, die Leiterbahnen und die Buchsen 8 kann so der Strom oder die Signale von den Leitern 26 der linearen Versorgungseinheit 20 an die Endgeräte weitergegeben werden. Soll im vorliegenden Fall ein Leiter 26 einer anderen, benachbarten Kammer 24 durch ein Kontaktelement 6 kontaktiert werden, kann das Kontaktelement 26 wie oben bereits erwähnt entlang der Strombrücke 4 in die neue Position verschoben werden, ohne dass dadurch eine neue Verkabelung der Kontaktelemente notwendig ist.The tap 1 follows in the exemplary embodiment Fig. 3 with its contact elements 6 into the chambers 24 of the linear supply unit 20 and contacts the conductors 26. The current or the signals from the conductors 26 of the linear supply unit 20 can be sent via the contact elements 6, the current bridges 4, the conductor tracks and the sockets 8 the end devices are passed on. If in the present case a conductor 26 of another, adjacent chamber 24 is to be contacted by a contact element 6, the contact element 26 can, as already mentioned above, be moved along the current bridge 4 into the new position without the need for new wiring of the contact elements.

Ein Treiber 28 eines Leuchtmittels ist in den Ausführungsbeispielen nach der Fig. 4 und 5 dargestellt. Der Treiber 28 ist dabei als Steuerelement des Leuchtmittels ausgebildet und umfasst dazu ohnehin eine Leiterplatte 2. Diese Leiterplatte 2 wird im vorliegenden Ausführungsbeispiel nun zusätzlich als Leiterplatte 2 für den Abgriff verwendet. Dadurch können die in den Fig. 1 bis 3 dargestellten Buchsen 8 eingespart werden, da die Weiterleitung der Energie und/oder Signale an das Endgerät, hier der Treiber 1 selbst, über die Leiterbahnen der Leiterplatte 2 realisiert werden kann.A driver 28 of a lamp is in the exemplary embodiments according to Figs. 4 and 5 shown. The driver 28 is designed as a control element of the lamp and includes a circuit board 2 anyway. In the present exemplary embodiment, this circuit board 2 is now additionally used as a circuit board 2 for the tap. This allows them to be in the Fig. 1 to 3 Sockets 8 shown can be saved, since the forwarding of the energy and / or signals to the end device, here the driver 1 itself, can be realized via the conductor tracks of the circuit board 2.

Auf die Leiterplatte 2 des Treibers 28 werden daher die bereits in den Ausführungsbeispielen nach Fig. 1 bis 3 verwenden Elemente zur Kontaktierung in gleicher Art und Weise angeordnet. Somit wird auch hier eine Anzahl von Strombrücken 4 verwendet, auf die die Kontaktelemente 6 verschiebbar angeordnet werden. Und auch eine Schutzabdeckung 12 mit einer Anzahl von Öffnungen 14 ist vorgesehen, die sich nun wahlweise über den gesamten Treiber 28 erstrecken kann oder wie in den Ausführungsbeispielen nach Fig. 4 und 5 dargestellt nur über den Bereich der Leiterplatte 2, in der die Elemente zur Kontaktierung angeordnet sind.The circuit board 2 of the driver 28 is therefore already used in the exemplary embodiments Fig. 1 to 3 Use elements for contacting arranged in the same way. This means that there are a number of current bridges here too 4 used, on which the contact elements 6 are displaceably arranged. And a protective cover 12 with a number of openings 14 is also provided, which can now optionally extend over the entire driver 28 or as in the exemplary embodiments Figs. 4 and 5 shown only over the area of the circuit board 2, in which the elements for contacting are arranged.

Insgesamt sei erwähnt, dass die Kontaktelemente 6 selbstverständlich nicht auf die hier dargestellten Kontaktelemente 6 beschränkt sind, sondern je nach verwendeten Leitern 26 oder Kammern 24 auch andere Kontaktelemente 6, beispielsweise Piercingkontakte oder eine seitliche Kontaktierung der Leiter 26, möglich sind.Overall, it should be mentioned that the contact elements 6 are of course not limited to the contact elements 6 shown here, but depending on the conductors 26 or chambers 24 used, other contact elements 6, for example piercing contacts or lateral contacting of the conductors 26, are also possible.
