Abstract

L'invention concerne une unité d'empilage destinée à recevoir des plaques de noyau pour un composant inductif, comprenant une pluralité d'éléments d'empilage dans ou sur chacun desquels une des plaques de noyau est maintenue. Les éléments d'empilage sont configurés de telle sorte qu'une partie d'un élément d'empilage peut être logée dans une partie d'un autre élément d'empilage et les éléments d'empilage individuels ainsi que les plaques de noyau qui y sont logées peuvent être empilés les uns sur les autres.
