Abstract

L'INVENTION CONCERNE UN COUPE-CIRCUIT THERMIQUE A FUSIBLE DU TYPE A RETABLISSEMENT AUTOMATIQUE. CE COUPE-CIRCUIT EST CONCU POUR ROMPRE LA CONTINUITE ELECTRIQUE ENTRE DEUX FILS CONDUCTEURS 2A, 2B PAR FUSION D'UN ELEMENT THERMOSENSIBLE 7 LORSQUE LA TEMPERATURE AMBIANTE ATTEINT UNE VALEUR PREDETERMINEE. EN FONDANT, CET ELEMENT 7 AUGMENTE DE VOLUME AFIN D'ELOIGNER UN ORGANE 4 DE CONTACT D'UNE BORNE 3A SITUEE A L'EXTREMITE DE L'UN 2A DES FILS CONDUCTEURS. UN RESSORT 5 RAMENE L'ORGANE 4 DE CONTACT CONTRE LA BORNE 3A AU FUR ET A MESURE QUE L'ELEMENT 7 SE SOLIDIFIE EN DIMINUANT DE VOLUME, UNE FOIS QUE LA TEMPERATURE AMBIANTE EST RETOMBEE AU-DESSOUS DE LA TEMPERATURE PREDETERMINEE. DOMAINE D'APPLICATION: APPAREILS ELECTRIQUES, UTILISATION A LA PLACE DE THERMOSTATS, ETC.
