Abstract

UN CELULA ELECTROQUIMICA DE TIPO CILINDRICO CON UNA CUBIERTA METALICA (12), UN ANODO (18), UN SEPARADOR (20) Y UN CATODO (14) COLOCADOS CONCENTRICAMENTE UNO RESPECTO AL OTRO, EN UNA SOLUCION ELECTROLITICA, ALCALINA, ACUOSA, Y UN DISPOSITIVO DE CIERRE. EL DISPOSITIVO DE CIERRE CONSTA DE UNA TAPA DE PLASTICO (28) QUE SE INSERTA EN EL EXTREMO ABIERTO DE LA CUBIERTA (12) Y TIENE UNA ZONA CILINDRICA EXTERIOR, UN REBORDE INFERIOR (40), UNA PORCION CENTRAL (34) QUE DEFINE UN AGUJERO CENTRAL Y UNA PORCION INTERMEDIA (38) QUE INTERCONECTA LA PORCION CENTRAL CON EL REBORDE INFERIOR. A TRAVES DEL AGUJERO CENTRAL SE INTRODUCE UN CLAVO DE TOMA DE CORRIENTE (26) EL CUAL PENETRA PROFUNDAMENTE EN EL ANODO. UNA CUBIERTA NEGATIVA (24) DE UN MATERIAL DE HOJA METALICA FORMA EL TERMINAL NEGATIVO DE LA CELULA. LA CUBIERTA NEGATIVA TIENE UNA PORCION SALIENTE (47) QUE TERMINA EN UN REBORDE DOBLADO HACIA ADENTRO (48), LA CUBIERTA TIENE UN AISLADOR TIPO PERLA (30) A UNA DISTANCIA PREDETERMINADA DE SU EXTREMO ABIERTOY EL AISLADOR TIPO PERLA ACTUA COMO MIEMBRO DE TOPE PARA EL DISPOSITIVO DE CIERRE CUANDO ESTE SE INSERTA EN LA CUBIERTA.. LA TAPA DE PLASTICO DEFINE UNA SUPERFICIE DE SOPORTE CONFORMADORA PARA EL REBORDE DOBLADO HACIA ADENTRO EN SUSTANCIALMENTE LA ZONA DE CONEXION DE LA ZONA CILINDRICA EXTERIOR Y EL REBORDE INFERIOR. LA CUBIERTA TIENE UNA ZONA OBTURADORA (31) POR ENCIMA DEL AISLADOR TIPO PERLA Y SE APLICA UN SELLADOR PARA CUBRIR LA SUPERFICIE INTERIOR DE LA CUBIERTA EN LA ZONA OBTURADORA. LA PORCION FINAL DE LA ZONA OBTURADORA PLIEGA QUEDANDO SOBRE EL REBORDE DOBLADO HACIA ADENTRO DE TAL MODO QUE LA ZONA CILINDRICA EXTERIOR DE LA TAPA DE PLASTICO QUEDE PRESIONADA Y FIJADA POR PRESION ENTRE MEDIAS CON LO QUE EL REBORDE DOBLADO HACIA ADENTRO PROPORCIONA UNA ACCION DE RESORTE PRESIONANDO LA ZONA CILINDRICA EXTERIOR EN UNA DIRECCION RADIAL HACIA LA ZONA OBTURADORA Y EN UNA DIRECCION AXIAL HACIA EL AISLADOR TIPO PERLA.
