Abstract

UN MONTAJE DE INTERRUPTOR TERMICO UNITARIO AUTONOMO (10) QUE TIENE UNA CARCASA DE CONMUTADOR SELLADA HUECA FORMADA POR UN COLECTOR (12) Y UNA TAPA (14) QUE SIRVEN COMO CONTACTOS DE CONMUTACION. SEPARANDO EL COLECTOR Y LA TAPA HAY UN REVESTIMIENTO AISLANTE DE PLASTICO (16) QUE GENERALMENTE SIGUE EL CONTORNO INTERIOR DEL COLECTOR (12). LA TAPA (14) SE MANTIENE EN SU LUGAR EN EL EXTREMO ABIERTO DEL COLECTOR PLEGANDO EL REBORDE SUPERIOR DEL COLECTOR QUE, AL MISMO TIEMPO, SE PLEGARA SOBRE EL AISLADOR EN FORMA DE U EN TORNO AL BORDE DE LA TAPA Y SUJETARA Y AISLARA LA TAPA EN UNA RELACION ESPACIADA CON EL COLECTOR. UN COLECTOR DE MEMORIA DE FORMA (18) FORMADO COMO UN TROZO DE HILO RECTO ESTA SITUADO ENTRE LA TAPA (14) Y EL LADO DEL COLECTOR (12) OPUESTO A LA TAPA (14). EL HILO SE MANTIENE EN ALINEACION MEDIANTE UNA ABERTURA A TRAVES DEL AISLADOR (16) QUE SOPORTA UNA PARTE DE EXTREMO DEL HILO ADYACENTE AL FONDO DEL COLECTOR (12). CUANDO SE SOMETE EL CORTE TERMICO A UNA TEMPERATURA IGUAL O SUPERIORA LA TEMPERATURA DE RECUPERACION DEL CONDUCTOR DE MEMORIA DE FORMA (18), EL CONDUCTOR CAMBIARA A SU FORMA RECUPERADA Y ABRIRA EL CIRCUITO. SI ES NECESARIO UN CIRCUITO DE RESISTENCIA ELEVADA A TRAVES DEL INTERRUPTOR TERMICO ABIERTO, EL AISLADOR DE PLASTICO (16) PUEDE MOLDEARSE DE UN COMPUESTO PARCIALMENTE CONDUCTIVO UTILIZANDO UNA MEZCLA COMO POLIPROPILENO Y NEGRO DE HUMO DE GAS NATURAL.
