Abstract

LA PRESENTE INVENTION CONCERNE UN CIRCUIT MAGNETIQUE POUR INDUCTANCE AINSI QUE DES INDUCTANCES UTILISANT UN TEL CIRCUIT MAGNETIQUE. ELLE CONCERNE EGALEMENT UN PROCEDE DE REALISATION DUDIT CIRCUIT MAGNETIQUE. SELON L'INVENTION, LE CIRCUIT MAGNETIQUE EST CONSTITUE PAR UN PARRALLELEPIPEDE COMPORTANT AU MOINS DEUX GORGES 6, 7 DISPOSEES SENSIBLEMENT L'UNE AU-DESSUS DE L'AUTRE DANS LESQUELLES EST DISPOSE UN BOBINAGE 24, LEDIT CIRCUIT MAGNETIQUE AYANT SENSIBLEMENT LA FORME D'UN H DANS UN PLAN PERPENDICULAIRE AUX GORGES. LES BRANCHES INFERIEURES 3, 15 DUDIT CIRCUIT MAGNETIQUE SONT MUNIES DE MOYENS DE CONNEXIONS ELECTRIQUES 19, 20. CECI PERMET DE FIXER SOLIDEMENT ET SANS DIFFICULTE LES INDUCTANCES AINSI REALISEES SOIT SUR DES CIRCUITS IMPRIMES, SOIT DIRECTEMENT SUR DES SUPPORTS DE CIRCUITS HYBRIDES. APPLICATION : INDUCTANCE MINIATURE.
