Die Erfindung betrifft ein Betriebsgerät für elektrische Lampen gemaß dem Obergriff des Schutzanspruchs 1.The invention relates to an operating device for electric lamps according to the preamble of protection claim 1.

Derartige Betriebsgeräte werden insbesondere zum Betrieb von Leuchtstofflampen und Niedervolthalogenglühlampen benötigt.
Sie bestehen aus einer auf die elektrischen Eigenschaften der zu betreibenden Lampen abgestimmten elektrischen Schaltungsanordnung, einem Gehäuse, das die Schaltungsanordnung umschließt, und einem lampenseitigen Anschlußteil, das zum Anschluß der Lampen an das Betriebsgerät dient, sowie einem netzseitigen Anschlußteil, über das das Betriebsgerät mit einer elektrischen Spannungsquelle verbunden ist.Operating devices of this type are required in particular for the operation of fluorescent lamps and low-voltage halogen incandescent lamps.
They consist of an electrical circuit arrangement that is matched to the electrical properties of the lamps to be operated, a housing that encloses the circuit arrangement, and a lamp-side connection part that serves to connect the lamps to the operating device, and a network-side connection part, via which the operating device connects to a electrical voltage source is connected.

Die Anschlußteile gebräuchlicher Betriebsgeräte sind üblicherweise mit einer Zugentlastungsvorrichtung für jeweils zwei Anschlußkabel ausgerüstet. Ein Nachteil dieser Betriebsgeräte besteht darin, daß die Zugentlastungsvorrichtungen ihrer Anschlußteile nur für einen bestimmten Kabeltyp geeignet sind.The connecting parts of common operating devices are usually equipped with a strain relief device for two connecting cables. A disadvantage of these operating devices is that the strain relief devices of their connecting parts are only suitable for a certain type of cable.

Es ist die Aufgabe der Erfindung, ein Betriebsgerät für elektrische Lampen bereitzustellen, bei dem zumindest das netzseitige Anschlußteil eine Zugentlastungsvorrichtung besitzt, die für unterschiedliche Anschlußkabel geeignet ist.It is the object of the invention to provide an operating device for electric lamps in which at least the mains-side connection part has a strain relief device which is suitable for different connection cables.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Schutzanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved by the characterizing features of claim 1. Particularly advantageous embodiments of the invention are described in the subclaims.

Das netzseitige Anschlußteil des erfindungsgemäßen Betriebsgerätes ist mit einer zweiteiligen Zugentlastungsvorrichtung ausgestattet. Sie besteht aus einem Basisteil und einem mit diesem verschraubbaren Bügel, zwischen denen die Anschlußkabel eingeklemmt werden. Der Bügel ist mit zwei unterschiedlich strukturierten, jeweils zwei Vertiefungen aufweisenden Oberflächen versehen, die wahlweise mit einer ebenfalls Vertiefungen besitzenden Oberfläche des Basisteils zusammenwirken können, um die Anschlußkabel klemmend zu fixiern. Die Vertiefungen in den Oberflächen des Bügels und des Basisteils bilden dabei Durchführungen für die Anschlußkabel. Durch Wenden des Bügels ist es möglich, zwei Anschlußkabel gleichen oder unterschiedlichen Querschnitts in die Zugentlastungsvorrichtung einzuspannen. Diese Zugentlastungsvorrichtung erlaubt es, alle gängigen Kabeltypen zu entlasten. Ferner ist es möglich, auch nur ein einziges Kabel in dieser Vorrichtung zu montieren, ohne daß der Bügel verkantet, was eine Deformation des Gehäuses zur Folge hätte.The network-side connection part of the operating device according to the invention is equipped with a two-part strain relief device. It consists of a base part and a bracket that can be screwed to it, between which the connecting cables are clamped. The bracket is provided with two differently structured surfaces, each having two recesses, which can optionally interact with a surface of the base part which also has recesses in order to fix the connecting cable in a clamped manner. The depressions in the surfaces of the bracket and the base part form bushings for the connection cable. By turning the bracket, it is possible to clamp two connecting cables of the same or different cross-section in the strain relief device. This strain relief device allows all common cable types to be relieved. Furthermore, it is possible to mount even a single cable in this device without the bracket tilting, which would result in deformation of the housing.
