Description

Die Erfindung bezieht sich auf einen z.B. aus der GB-A-2 120 024 bekannten Adapter mit einem Gehäuse zum Anschluß von Gasentladungslampen beziehungsweise Niederspannungsglühlampen an Stromschienen von im wesentlichen U-förmigen Querschnitt, in deren Innerem spannungsführende Leiter angeordnet sind und das Gehäuse einen ersten Abschnitt aufweist, der bei funktionsgerechtem Einsatz in das Innere der Schiene ragt und der verstellbare Riegelglieder aufweist zur Fixierung des Adapters an der Stromschiene und ferner verstellbare elektrisch leitende Kontaktfahnen zum elektrischen Anschluß des Verbrauchers und ferner einen außerhalb der Stromschiene liegenden zweiten Abschnitt mit Stellhebel zur Betätigung der Riegelglieder und/oder der Kontaktfahnen und an diesem zweiten Abschnitt die Gasentladungslampe direkt oder indirekt angeschlossen ist.The invention relates to e.g. from GB-A-2 120 024 known adapter with a housing for connecting gas discharge lamps or low-voltage incandescent lamps to busbars of substantially U-shaped cross section, inside which live conductors are arranged and the housing has a first section, which is used in a functional manner in the interior of the rail protrudes and the adjustable locking members have for fixing the adapter to the power rail and also adjustable electrically conductive contact tabs for the electrical connection of the consumer and also a second section lying outside the power rail with actuating lever for actuating the locking members and / or the contact tabs and on this second section, the gas discharge lamp is connected directly or indirectly.

Unter dem Begriff "Adapter" werden Anschlußvorrichtungen verstanden, mit welchen der Verbraucher nicht nur mechanisch und elektrisch mit der Stromschiene verbunden werden kann, diese Adapter lassen sich auch entlang der Stromschiene verschieben, so daß der Verbraucher an jeder beliebigen Stelle der Stromschiene angeschlossen werden kann. Als Verbraucher kommen bei solchen Stromschienen vor allem Leuchten in Betracht. Solche Stromschienen werden in Schaufenstern montiert zur Ausleuchtung derselben, in Ausstellungsräumen, aber auch in Wohn- und Arbeitsräumen. Wurden bislang die Leuchten mit herkömmlichen Glühlampen bestückt, die direkt und unmittelbar mit Netzspannung betrieben werden, so sind Bestrebungen im Gange, auch hier Niederspannungsglühlampen, bzw. Gasentladungslampen einzusetzen und zwar aus jenen Gründen, die für die Verwendung dieser Lampen sprechen. Solche Lampen können aber nicht mit der üblichen Netzspannung betrieben werden. Gasentladungslampen benötigen Vorschaltgeräte, und die Niederspannungsglühlampen benötigen zur Erzeugung der hier erforderlichen Betriebsspannung einen Frequenz- und Spannungswandler.The term "adapter" is understood to mean connecting devices with which the consumer can not only be mechanically and electrically connected to the busbar, these adapters can also be moved along the busbar, so that the consumer can be connected at any point on the busbar. Luminaires in particular are considered as consumers in such busbars. Such busbars are installed in shop windows to illuminate them, in exhibition rooms, but also in living and working spaces. So far, the luminaires have been equipped with conventional incandescent lamps that are operated directly and directly with mains voltage, efforts are underway to use low-voltage incandescent lamps or gas discharge lamps here, too, for the reasons that speak in favor of using these lamps. However, such lamps cannot be operated with the usual mains voltage. Gas discharge lamps require ballasts, and the low-voltage incandescent lamps require a frequency and voltage converter to generate the operating voltage required here.

Bisher wurden diese Geräte zum Betrieb der erwähnten Lampen unterhalb des Adapters in einem eigenen Gehäuse untergebracht was nicht nur einen unbefriedigenden Anblick bietet, sondern vor allem die Bauhöhe der Einrichtung als Ganzes außerordentlich vergrößert. Die gesamte Stromführungsschiene über einen Spannungs- und Frequenzwandler zu speisen, um für eventuell verwendete Niederspannungslampen die notwendigen Ströme und Spannungen zur Verfügung zu haben, ist aber praktisch nicht möglich. Da hier wegen der niedrigen Betriebsspannung von einigen Volt sehr hohe Ströme fließen, müßten in der Stromschiene Leiter mit großen Querschnitten untergebracht werden, wozu jedoch in diesen Schienen kein ausreichender Platz zur Verfügung steht.So far, these devices for operating the lamps mentioned have been accommodated in a separate housing below the adapter, which not only offers an unsatisfactory view, but above all greatly increases the overall height of the device as a whole. However, it is practically not possible to feed the entire current rail via a voltage and frequency converter in order to have the necessary currents and voltages available for any low-voltage lamps that may be used. Because of the low operating voltage of Very high currents flow a few volts, conductors with large cross-sections would have to be accommodated in the conductor rail, but there is not sufficient space available in these rails.

Die Erfindung zielt nun darauf ab, diese aufgezeigten Nachteile zu beseitigen, was vorschlagsgemäß dadurch gelingt, daß innerhalb des Gehäuses ein elektronisches Vorschaltgerät und/oder ein elektronischer Transformator vorgesehen ist und die das Vorschaltgerät bzw. den Transformator bildenden Schaltglieder wie Spulen, Kondensatoren, Widerstände, Transistoren u. dgl. auf mindestens einer Leiterplatte angeordnet sind.The invention is now aimed at eliminating these disadvantages, which is achieved according to the proposal in that an electronic ballast and / or an electronic transformer is provided within the housing and the switching elements forming the ballast or the transformer, such as coils, capacitors, resistors, Transistors and Like. Are arranged on at least one circuit board.

Die Zeichnung veranschaulicht die Erfindung, ohne sie auf die gezeigten Ausführungsbeispiele einzuschränken. Es zeigen: Fig. 1 einen Adapter in Ansicht; Fig. 2 in Seitensicht (Blickrichtung Pfeil A in Fig. 1); Fig. 3 in Seitensicht (Blickrichtung Pfeil B in Fig. 1); Fig. 4 eine Ansicht nach Fig. 1, jedoch ist das Gehäuse zum Teil aufgerissen und die Darstellung in einem vergrößertem Maßstab gegenüber Fig. 1; Fig. 5 ist eine Seitensicht (Pfeil B in Fig. 1), jedoch bei abgenommenem Gehäusedeckel und im selben Maßstab wie Fig. 4; Fig. 6 veranschaulicht die Ansicht eines weiteren Ausführungsbeispieles.The drawing illustrates the invention without restricting it to the exemplary embodiments shown. 1 shows an adapter in view; Fig. 2 in a side view (viewing direction arrow A in Fig. 1); Fig. 3 in a side view (viewing direction arrow B in Fig. 1); FIG. 4 is a view according to FIG. 1, but the housing is partially torn open and the illustration on an enlarged scale compared to FIG. 1; FIG. 5 is a side view (arrow B in FIG. 1), but with the housing cover removed and on the same scale as FIG. 4; 6 illustrates the view of a further exemplary embodiment.

Der Adapter nach den Fig. 1 bis 3, die ihn in verschiedenen Ansichten zeigen, besitzt ein Gehäuse 1 mit einem ersten oberen Abschnitt 2 und einem unteren Abschnitt 3. Bei funktionsgerechtem Einsatz ist der obere Abschnitt 2 von der hier nicht gezeigten Stromschiene zur Gänze aufgenommen, die in der Regel einen U-förmigen Querschnitt besitzt, in welchem spannungsführende Leiter liegen. An bzw. in diesem Abschnitt 2 sind Riegelglieder 4 und elektrische Kontaktfahnen 5, welche um eine hier gemeinsame Achse, die in der Zeichenebene (Fig. 1) liegt, schwenkbar sind, wobei in der eingeschwenkten Stellung diese Riegelglieder 4 und die Kontaktfahnen 5 vom oberen Abschnitt 2 des Gehäuses 1 zur Gänze aufgenommen werden, so daß dieser Abschnitt 2 in die Stromschiene eingefahren bzw. eingesetzt werden kann. Fig. 2 veranschaulicht diese Riegelglieder 4 und Kontaktfahnen 5 in ausgeschwenkter Stellung also in ihrer Aktivstellung. Zur Betätigung dieser Teile 4 und 5 dient hier eine gerändelte Scheibe 6. Die in diesem Zusammenhang verwendete Mechanik ist zweckmäßigerweise so ausgebildet, daß bei der aktiven Stellung der erwähnten Teile 4 und 5 diese verriegelt sind. Am Boden 7 des Gehäuses 1 ist ein Rohrstück befestigt, an welchem über ein Gelenk oder Scharnier, das hier nicht dargestellt ist, die eigentliche Leuchte angelenkt ist. Aus Herstellungs- und Montagegründen ist das Gehäuse 1 zweckmäßigerweise zweigeteilt gefertigt. Die Trennebene liegt parallel zur Zeichenebene bei der Darstellung nach Fig. 1. Die Trennlinie 9 der beiden Gehäuseteile ist aus Fig. 2 erkennbar. Die Trennebene steht bei der Darstellung nach Fig. 2 rechtwinkelig auf der Zeichenebene zu dieser Figur. Stirnseitig ist das Gehäuse 1 durch einen Gehäusedeckel 10 verschlossen, der mit dem Gehäuse 1 durch Riegelteile und/oder Schrauben 23 fest, jedoch lösbar verbunden ist.The adapter according to FIGS. 1 to 3, which show it in different views, has a housing 1 with a first upper section 2 and a lower section 3. When used correctly, the upper section 2 is completely taken up by the busbar, not shown here , which usually has a U-shaped cross section in which live conductors are located. On or in this section 2 are locking members 4 and electrical contact lugs 5, which are pivotable about a common axis here, which lies in the plane of the drawing (FIG. 1), these locking members 4 and the contact lugs 5 from the top in the pivoted-in position Section 2 of the housing 1 are completely included, so that this section 2 can be inserted or inserted into the busbar. Fig. 2 illustrates these locking members 4 and contact lugs 5 in the pivoted position, ie in their active position. A knurled disc 6 is used to actuate these parts 4 and 5. The mechanism used in this connection is expediently designed such that when the mentioned parts 4 and 5 are locked, they are locked. At the bottom 7 of the housing 1, a piece of pipe is attached, on which The actual lamp is articulated via a joint or hinge, which is not shown here. For manufacturing and assembly reasons, the housing 1 is advantageously made in two parts. The parting plane lies parallel to the drawing plane in the illustration according to FIG. 1. The parting line 9 of the two housing parts can be seen from FIG. 2. In the illustration according to FIG. 2, the parting plane is at right angles on the drawing plane to this figure. On the face side, the housing 1 is closed by a housing cover 10 which is firmly but releasably connected to the housing 1 by means of locking parts and / or screws 23.

Sind nun im linken Teil des Gehäuses 1 (Fig. 1 und 4) jene Mechanismen untergebracht, mit denen die Riegelglieder 4 und die Kontaktfahnen 5 verschwenkt werden, so ist im restlichen Teil des Gehäuses 1 das elektronische Vorschaltgerät bzw. der elektronische Transformator für den Betrieb der Lampe untergebracht. Die Bauteile für diese elektronischen Geräte, nämlich Spulen 11, Transistoren 12, Widerstände 13, Kondensatoren 14 u. dgl. mehr sind auf zwei Leiterplatten 15 und 16 angeordnet, welche zueinander rechtwinkelig stehen, und welche sich in Seitensicht (Fig. 5) als T- darstellen. Die eine Leiterplatte 16 liegt nahe am Boden 7 des Gehäuses 1 und zu ihm parallel, wogegen die dazu rechtwinkelig stehende zweite Leiterplatte 15 bis in den oberen Abschnitt 2 des Gehäuses 1 ragt, was sowohl die Fig. 4 wie auch die Fig. 5 anschaulich macht. Zur Halterung und Fixierung dieser Leiterplatten 15 und 16 im Inneren des Gehäuses sind schlitzartige Führungsnuten 17 und 18 vorgesehen, welche die Ränder der Leiterplatten 15 und 16 aufnehmen, wenn diese Leiterplatten bei der Montage seitlich (in der Richtung des Pfeiles 19 in Fig. 4) in das Gehäuse 1 eingeschoben werden.Are now housed in the left part of the housing 1 (Fig. 1 and 4) those mechanisms with which the locking members 4 and the contact tabs 5 are pivoted, so in the remaining part of the housing 1 is the electronic ballast or the electronic transformer for operation the lamp housed. The components for these electronic devices, namely coils 11, transistors 12, resistors 13, capacitors 14 u. The like. More are arranged on two printed circuit boards 15 and 16, which are at right angles to one another, and which in side view (FIG. 5) are represented as T-. The one printed circuit board 16 is close to the bottom 7 of the housing 1 and parallel to it, whereas the second printed circuit board 15, which is at right angles thereto, projects into the upper section 2 of the housing 1, which makes both FIGS. 4 and 5 clear . To hold and fix these circuit boards 15 and 16 in the interior of the housing, slot-like guide grooves 17 and 18 are provided, which receive the edges of the circuit boards 15 and 16 when these circuit boards laterally during assembly (in the direction of arrow 19 in FIG. 4). be inserted into the housing 1.

Innerhalb des Gehäuses 1 und mit den Kontaktfahnen 5 elektrisch leitend verbunden sind weitere Kontaktfahnen 20 und 21, die mit randseitigen, an der Leiterplatte 15 angeordneten Kontaktelementen 22, bei der Montage in elektrisch leitende Verbindung treten.Within the housing 1 and with the contact tabs 5 are further electrically connected contact tabs 20 and 21, which come into contact with the edge-side contact elements 22 arranged on the printed circuit board 15 during assembly.

Die beiden Leiterplatten 15 und 16 werden in der vorgesehenen Lage durch den das Gehäuse 1 seitlich abschließenden Gehäusedeckel 10 festgehalten. Dieser kann mit Schrauben 23 und eventuell einem Schnappriegel fixiert werden.The two printed circuit boards 15 and 16 are held in the intended position by the housing cover 10 which laterally closes the housing 1. This can be fixed with screws 23 and possibly a snap lock.

Wenn beim gezeigten Ausführungsbeispiel die Leiterplatten 15 und 16 von der Stirnseite her in das Gehäuse 1 eingesetzt und dabei über die Kontaktfahnen 20, 21, 22 mit den spannungsführenden Leitern in der Stromschiene verbunden werden, so liegt es im Rahmen der Erfindung, an einer Flachseite des Gehäuses 1 einen verschließbaren und abnehmbaren Gehäusedeckel anzuordnen, der parallel zur Zeichenebene bei der Darstellung nach den Fig. 1 und 4 liegen würde. Ferner wäre es auch möglich, die Leiterplatten 15 und 16, die ja miteinander fest verbunden sind, von unten her in das Gehäuse 1 einzufügen. Alle diese Möglichkeiten sind durchaus denkbar, wobei jedoch die in der Zeichnung dargestellte Montageart zweckmäßig erscheint, da hier im Inneren des Gehäuses 1 in Längsrichtung verlaufende Führungen 17 und 18 vorgesehen werden können, die den sicheren Halt der Leiterplatten innerhalb des Gehäuses gewährleisten.If, in the exemplary embodiment shown, the circuit boards 15 and 16 are inserted into the housing 1 from the front side and are connected to the live conductors in the conductor rail via the contact tabs 20, 21, 22, it is within the scope of the invention on a flat side of the Housing 1 to arrange a closable and removable housing cover, which would be parallel to the plane of the drawing in the representation of FIGS. 1 and 4. Furthermore, it would also be possible to insert the printed circuit boards 15 and 16, which are firmly connected to one another, from below into the housing 1. All of these possibilities are quite conceivable, but the type of assembly shown in the drawing appears expedient, since here longitudinal guides 17 and 18 can be provided inside the housing 1, which ensure the secure hold of the printed circuit boards within the housing.

Das Einfügen bzw. Einsetzen der Leiterplatten 15 und 16 von unten oder von der Seite her wäre dann als zweckmäßig zu betrachten, wenn am Adapter im Bereich beider Stirnseiten Kontaktfahnen 5 und Riegelglieder 4 sowie die dazugehörenden Stellglieder 6 vorhanden wären, wie dies beispielsweise Fig. 6 veranschaulicht, die einen solchen Adapter in Ansicht und schematisch zeigt. Der Deckel 24 ist hier absatzartig gestuft wie auch das Gehäuse 1 und ist - Fig. 6 - rechtwinkelig zur Zeichenebene nach oben abhebbar, wenn die Verbindungsmittel gelöst worden sind.The insertion or insertion of the printed circuit boards 15 and 16 from below or from the side would be considered expedient if contact tabs 5 and locking elements 4 and the associated actuators 6 were present on the adapter in the area of both end faces, as is the case, for example, in FIG. 6 illustrates which shows such an adapter in view and schematically. The cover 24 is here stepped like the housing 1 and - FIG. 6 - can be lifted upwards at right angles to the plane of the drawing when the connecting means have been released.

Ist beim Ausführungsbeispiel nach den Fig. 1 bis 3 das aus zwei getrennten Schalen gefertigte Gehäuse 1 an seiner einen Stirnseite mit einem Deckel 10 verschlossen, so liegt es im Rahmen der Erfindung, die Teilungsebene an einer anderen Stelle vorzusehen. Beispielsweise können in einem Gehäuseabschnitt - links der Teilungsebene - die mechanischen und elektrischen Riegel und Verbindungsglieder liegen, im anderen Gehäuseteil - rechts der Teilungsebene - die Leiterplatten 15 und 16. Auch in einem solchen Fall der Ausgestaltung des Gehäuses 1 kann für die Aufnahme und Führung dieser Leiterplatten 15 und 16 und für ihre Halterung eine relativ lange Führungsnut vorgesehen werden.If in the exemplary embodiment according to FIGS. 1 to 3 the housing 1 made of two separate shells is closed on one end side with a cover 10, it is within the scope of the invention to provide the division level at another location. For example, the mechanical and electrical latches and connecting links can be located in one housing section - to the left of the division level, and in the other housing part - to the right of the division level - the printed circuit boards 15 and 16. Also in such a case, the design of the housing 1 can accommodate and guide them Printed circuit boards 15 and 16 and a relatively long guide groove are provided for their mounting.

Da die vom Handel zur Verfügung gestellten elektronischen Bauteile sehr klein sind, können diese elektronischen Vorschaltgeräte bzw. Transformatoren in diesen Adaptern untergebracht werden, ohne daß das Gehäuse der bisherigen Adapter erheblich vergrößert werden muß.Since the electronic components available from retailers are very small, these electronic ballasts or transformers can be used in them Adapters can be accommodated without the housing of the previous adapter having to be significantly enlarged.

Ist bei den gezeigten Ausführungsbeispielen vorgesehen, daß am Boden 7 des Gehäuses ein Rohrstück 8 herausgeführt wird, welches als Träger für die Lampe oder Leuchte dient, so wäre es grundsätzlich möglich, hier auch ein Kabel herauszuleiten, welches endseitig dann mit einem oder mehreren Beleuchtungskörpern verbindbar ist.If it is provided in the exemplary embodiments shown that a tube piece 8 is led out on the bottom 7 of the housing and serves as a support for the lamp or light fixture, it would in principle be possible to lead out a cable here, which can then be connected at the end to one or more lighting fixtures is.

Beim gezeigten Ausführungsbeispiel sind im Adapter 2 Leiterplatten 15 und 16 angeordnet. Wenn ein Vorschaltgerät oder ein Transformator benötigt wird, der eine geringere elektrische Leistung aufweist, so liegt es im Rahmen der Erfindung, die das Vorschaltgerät bzw. den Transformator bildenden Schaltglieder auf einer einzigen Leiterplatte anzuordnen. Diese Leiterplatte kann entweder parallel zum Boden 7 des Gehäuses vorgesehen sein oder aber dazu senkrecht stehend. In der Regel wird man der aufrechten Anordnung der Leiterplatte den Vorzug einräumen.In the embodiment shown, 2 circuit boards 15 and 16 are arranged in the adapter. If a ballast or a transformer is required which has a lower electrical power, it is within the scope of the invention to arrange the switching elements forming the ballast or the transformer on a single printed circuit board. This circuit board can either be provided parallel to the bottom 7 of the housing or standing perpendicular to it. As a rule, preference will be given to the upright arrangement of the circuit board.
