Abstract

THERMORUPTEUR EN FORME DE DISQUE. UN CONTACT ELASTIQUE EN FORME DE CUVETTE EST AJUSTE SUR UN ISOLATEUR DE CERAMIQUE QUI ENTOURE UN FIL. LE CENTRE DE LA CUVETTE DE CONTACT EST DECOUPE SUIVANT UN DESSIN QUI LUI CONFERE DE LA FLEXIBILITE ET UN DISQUE METALLIQUE PLACE CONTRE LA SURFACE DE CETTE CUVETTE DE CONTACT EN APPLIQUE LES PARTIES FLEXIBLES CONTRE LA TETE DU FIL QUI SUPPORTE L'ISOLATEUR DE CERAMIQUE. LE BOITIER EN FORME DE COUPELLE EST CONDUCTEUR ET LOGE ETROITEMENT LE CONTACT DE MANIERE A BOUCLER LE CIRCUIT AVEC LUI. UN SECOND FIL EST FIXE A LA SURFACE EXTERIEURE DE CE BOITIER ET UNE PASTILLE DE MATIERE THERMOFUSIBLE EST MONTEE ENTRE CE DERNIER ET LE DISQUE METALLIQUE DE MANIERE QUE, LORSQU'IL FOND, LES PARTIES FLEXIBLES DE LA CUVETTE DE CONTACT S'ECARTENT DE L'AUTRE FIL. APPLICATION AUX THERMORUPTEURS MINIATURES.
