Description

Die Erfindung betrifft einen Adapter für Stromschienen nach dem Oberbegriff des Anspruchs 1.The invention relates to an adapter for busbars according to the preamble of claim 1.

Bei einem bekannten Adapter dieser Art sind die beiden Schenkel über eine Schwenkachse miteinander verbunden. Die Schenkel werden unter Federkraft gegeneinandergedrückt, ähnlich wie dies bei Wäschefederklammern der Fall ist. Die Kontakte liegen unter Federvorspannung an den Stromleitern der umgriffenen Stromschiene an. Ein wesentlicher Nachteil dieses bekannten Adapters liegt darin, daß er nicht gegen ein unbeabsichtigtes Abstreifen gesichert ist. Die Fixierung erfolgt ausschließlich über Federkraft. Außerdem erweist es sich als nachteilig, daß die elektrischen Kontakte gleichzeitig die mechanischen Halteelemente des Adapters darstellen.In a known adapter of this type, the two legs are connected to one another via a pivot axis. The legs are pressed against each other under spring force, similar to the case with clothes pegs. The contacts are spring-loaded on the conductors of the encompassed busbar. A major disadvantage of this known adapter is that it is not secured against unintentional stripping. The fixation takes place exclusively by spring force. In addition, it proves disadvantageous that the electrical contacts simultaneously represent the mechanical holding elements of the adapter.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Adapter der als bekannt vorausgesetzten Art zu schaffen, der in seiner Gebrauchslage arretierbar ist und bei dem voneinander unterschiedliche elektrische Kontaktelemente und mechanische Halteelemente vorgesehen sind.Based on this prior art, the invention has for its object to provide an adapter of the type presumed to be known, which can be locked in its position of use and in which different electrical contact elements and mechanical holding elements are provided.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß mindestens ein Schenkel gradlinig bewegbar und in der Anlageposition der elektrischen Kontakte an den Stromleitern der Stromschiene und bei Eingriff von Halteelementen in Ausnehmungen der Stromschiene arretierbar ist.This object is achieved according to the invention in that at least one leg can be moved in a straight line and can be locked in the contact position of the electrical contacts on the current conductors of the busbar and upon engagement of holding elements in recesses in the busbar.

Der erfindungsgemäße Adapter hat den Vorteil, daß er gegen unbeabsichtigtes Lösen von der Stromschiene gesichert ist. Darüberhinaus kann er sehr paßgenau mit der Stromschiene verbunden werden, so daß eine besonders genaue Zuordnung zwischen Adapter und Stromschiene im Verbindungszustand gewährleistet ist.The adapter according to the invention has the advantage that it is secured against unintentional detachment from the busbar. In addition, it can be connected to the busbar with a very precise fit, so that a particularly precise assignment between the adapter and the busbar is ensured in the connected state.

Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung erläutert. Es zeigen:

eine perspektivische Darstellung des Adapters im Verriegelungszustand vor einer perspektivischen Darstellung eines Teiles der zugehörigen Stromschiene,
Figur 2 -
eine Ansicht auf den Adapter gemäß Figur 1 von unten bei entferntem Halterohr 7.
A preferred embodiment of the invention is explained below with reference to the drawing. Show it:
Figure 1 -
1 shows a perspective illustration of the adapter in the locked state before a perspective illustration of a part of the associated conductor rail
Figure 2 -
2 shows a view of the adapter according to FIG. 1 from below with the holding tube 7 removed.

Der Adapter weist ein längliches metallisches Basisteil 12 auf, das auf einer Seite zwei Führungsstifte 13 und 15 und auf der anderen Seite zwei Führungsstifte 16 und 14 aufweist. Auf den Führungsstiften sind die unteren Enden von zwei Schenkeln 1 und 5 querverschieblich geführt. Die Führungsstifte werden von Druckfedern 17 umgeben, welche die beiden Schenkel 1 und 5 auseinanderdrücken.The adapter has an elongated metallic base part 12 which has two guide pins 13 and 15 on one side and two guide pins 16 and 14 on the other side. On the guide pins, the lower ends of two legs 1 and 5 are guided so that they can move. The guide pins are surrounded by compression springs 17 which press the two legs 1 and 5 apart.

Aus der in Figur 2 dargestellten, auseinandergefahrenen Lage können die Schenkel 1 und 5 in die in Figur 1 dargestellte Anlageposition und Verriegelungsposition verfahren werden. In der Anlage- und Verriegelungsposition liegen die elektrischen Kontakte 2, welche in beiden Schenkeln 1 und 5 und auf gleicher Höhe angeordnet sind, an den Stromleitern 21a und 22a der Stromschiene 20 an. Die Stromleiter sind in Aufnahmenuten 21 und 22 angeordnet. In die Aufnahmenuten 21 und 22 greifen die an beiden Stirnseiten in beiden Schenkeln vorgesehenen Haltenasen 3 und 4 ein. In dieser Eingriffsposition, in der auch die Kontakte an den elektrischen Leitern anliegen, wird der Adapter mit Hilfe eines Arretierhebels 6 gesichert:
Ein Zugbolzen 11 besitzt einen Kopf 11a, der fest mit dem Schenkel 1 verbunden ist. Der Zugbolzen 11 durchsetzt das Basisteil 12 und ist in einer Durchgangsbohrung frei querverschieblich bewegbar. Am dem Kopf 11a gegenüberliegenden Ende ist auf dem Zugbolzen 11 ein als Winkelhebel ausgebildeter Arretierhebel 6 schwenkbar um eine Achse 18 gelagert. Die Achse 18 wird von einem Spannstift gebildet, der den doppelt, also auf Unterseite und Oberseite des Schaftes des Zugbolzens vorgesehenen Winkelschenkel 6b durchsetzt und in einer Querbohrung des Schaftes des Zugbolzens 11 gelagert ist. Der Arretierhebel 6 besitzt außer dem doppelt vorgesehenen Winkelschenkel 6b einen äußeren Winkelschenkel 6a, der zur Betätigung dient. Bei einem Verschwenken des Winkelhebels 6 aus der in Figur 2 dargestellten Position in die Position gemäß Figur 1, also in die Arretierposition, läuft der Winkelschenkel 6b an einer exzentrisch zur Schwenkachse 18 verlaufenden Gleitfläche 19 des Schenkels 5 ab. Hierdurch werden die beiden Schenkel 1 und 5 mittels des Zugbolzens 11 unter Überwindung der Kraft der Federn 17 bis in die in Figur 1 dargestellte Lage gezogen.From the one shown in Figure 2, moved apart Position the legs 1 and 5 can be moved into the contact position and locking position shown in Figure 1. In the contact and locking position, the electrical contacts 2, which are arranged in both legs 1 and 5 and at the same height, bear against the current conductors 21a and 22a of the busbar 20. The current conductors are arranged in grooves 21 and 22. The retaining lugs 3 and 4 provided on both end faces in both legs engage in the receiving grooves 21 and 22. In this engagement position, in which the contacts also rest on the electrical conductors, the adapter is secured with the aid of a locking lever 6:
A tension bolt 11 has a head 11 a, which is firmly connected to the leg 1. The tension bolt 11 passes through the base part 12 and can be moved freely in a through bore. At the end opposite the head 11a, a locking lever 6, designed as an angle lever, is pivotably mounted about an axis 18 on the tension bolt 11. The axis 18 is formed by a dowel pin which passes through the angle leg 6b provided twice on the underside and top of the shank of the draw bolt and is mounted in a transverse bore in the shank of the draw bolt 11. The locking lever 6 has, in addition to the double provided angle leg 6b, an outer angle leg 6a, which is used for actuation. When the angle lever 6 is pivoted from the position shown in FIG. 2 into the position according to FIG. 1, that is to say into the locking position, the angle leg 6b runs on a sliding surface extending eccentrically to the pivot axis 18 19 of the leg 5 from. As a result, the two legs 1 and 5 are pulled by means of the tension bolt 11 while overcoming the force of the springs 17 into the position shown in FIG. 1.

Die elektrischen Kontakte 2 sind an entsprechenden Kontaktfahnen 8 vorgesehen, an die Stromleiter 9 und 10 angelötet sind. Die Stromleiter 9 und 10 durchsetzen ein am Basisteil 12 befestigtes Auslegerohr 7, welches an seinem unteren Ende einen Bestandteil eines Schwenkgelenkes für eine Leuchte trägt. In Figur 2 ist der besseren Darstellung wegen das Halterohr 7 nicht dargestellt.The electrical contacts 2 are provided on corresponding contact lugs 8, to which the current conductors 9 and 10 are soldered. The current conductors 9 and 10 pass through an extension tube 7 fastened to the base part 12, which carries at its lower end a component of a swivel joint for a lamp. For better illustration, the holding tube 7 is not shown in FIG. 2.
