Abstract
Condensateur accordable. Le condensateur comporte deux disques métallisés 18, 22 entre lesquels est emprisonné un rotor 20 muni d'une colonne centrale 34 qui traverse des ouvertures centrales formées dans les disques et est munie d'un évidement 36 destiné à recevoir un outil d'accord. Le condensateur est monté dans un boîtier 12 en matière plastique, la colonne 34 étant montée à frottement dans une ouverture 64 du corps 14 du boîtier et son évidement 36 étant ainsi accessible de l'extérieur. Un fond 16, monté à frottement et éventuellement collé, ferme le dessous de corps et comporte des fentes 66, 68 pour le passage des conducteurs 48, 60 du condensateur. Application à des condensateurs accordables miniatures.
