Abstract (en)

[origin: WO2004077459A1] The invention relates to an insulating element for integrating into the hole of a toiroidal core (2), said element consisting of a number n = 2 of radially outwardly extending sections (31, 32, 33), at least one section (31, 32, 33) comprising a spring element (4) which can be elastically deformed in the radial direction. The invention also relates to a toroidal core (2), a method for applying windings to said toroidal core (2), and a toroidal choke core. Tolerances in the diameter of the core hole can be compensated by means of the inventive insulating element (1).
