Abstract

1. Holding device made of plastic material for toroidal transformers provided with windings, which is composed of a carrier member (2) adapted on the external diameter of the toroidal transformer winded (f) and having a centering pin (3) disposed centrally and especially formed as a hollow cylinder, on which the toroidal transformer winded is fixed by means of sealing material (4), characterized in that the carrier member (2) is formed as a circular plate with means (8, 12) serving to hind at fixing of the holding device on a support (15) a distortion of the holding device relatively against said support.
