Abstract

Die vorliegende Erfindung betrifft eine Montagevorrichtung für eine ein magnetisch leitendes Kernelement (1) aufweisende Spulenvorrichtung, insbesondere für einen Transformator und eine Drossel, zur Verspannung des Kernelements. Um bei bekannten Montagevorrichtungen Ströme in Montageschrauben, die durch Querbohrungen in dem Kernelement zur Montage der Montagevorrichtung an dem Kernelement geführt sind, was zu zusätzlichen Wärmeverlusten führt, zu verhindern, ist erfindungsgemäß vorgesehen, dass die Montagevorrichtung (2) an gegenüberliegenden Seiten des Kernelements (1) anzubringende Formteile (20, 21) aufweist und dass die Formteile (20, 21) jeweils mindestens einen Steg (22) aufweisen zur Einbringung in korrespondierende, in dem Kernelement (1) angebrachte Bohrungen (3), wobei die Stege (22) so ausgestaltet und angeordnet sind, dass sich bei an der Spulenvorrichtung angebrachter Montagevorrichtung Stege (22) unterschiedliche Formteile (20, 21) nicht berühren.

The present invention relates to a mounting device for a magnetically conductive core element (1) having coil device, in particular for a transformer and a choke, for clamping the core element. In order to prevent in known mounting devices currents in mounting screws, which are guided by transverse holes in the core element for mounting the mounting device on the core element, resulting in additional heat losses, according to the invention it is provided that the mounting device (2) on opposite sides of the core element (1 ) and that the molded parts (20, 21) each have at least one web (22) for introduction into corresponding, in the core element (1) mounted holes (3), wherein the webs (22) so are configured and arranged that when mounted on the coil device mounting device webs (22) different mold parts (20, 21) do not touch.
