Abstract

Une couche (4) de résine tendre à bas point de fusion est liée à une résistance (2). Un conducteur (3) en papier non combustible est fixé à la surface supérieure de la couche (4) de résine tendre. Les bords opposés de la résistance (2) sont dotés de bandes d'électrode (9, 9) et de bornes (10, 10), les bornes (10, 10) étant connectées à un contrôleur (6). Le conducteur (3) est formé par impression d'encre conductive sur une surface d'une feuille de papier non combustible (12), et une borne (11) de détection de courant de fuite, laquelle est comprimée en contact dans le conducteur (3), est connectée à la borne du contrôleur (6) par un fil conducteur. Lorsque la résistance (2) atteint des températures anormales, la couche (4) de résine tendre fond, de telle manière que le conducteur (3) et la résistance (2) viennent en contact mutuel, produisant un courant de fuite lequel est détecté, coupant ainsi l'alimentation.
