Insulating element, toroidal core, toroidal core choke, and method for producing said toroidal core choke

摘要

The invention relates to an insulating part for fitting into the core hole of a toroidal core ( 2 ), containing a number n>=2 of webs ( 31, 32, 33 ) running radially outwards, whereby at least one web ( 31, 32, 33 ) has a spring element ( 4 ) elastically deformable in the radial direction. Furthermore, the invention relates to a toroidal core ( 2 ), a method for the winding of the toroidal core ( 2 ) and a toroidal core choke. Tolerances in the core hole diameter can easily be compensated for by the insulating part ( 1 ).
