Abstract

EL OBJETIVO DE LA INVENCION ES ATENUAR LAS EMISIONES ELECTROMAGNETICAS DE APARATOS ELECTRONICOS, ESPECIALMENTE DE AQUELLOS QUE UN TABLERO DE CIRCUITOS IMPRESOS, UNA CARCASA CONDUCTORA Y QUE REQUIEREN CONEXIONES EXTERNAS A OTROS DISPOSITIVOS. LA DISPOSICION INCLUYE UNA SEPARACION DEL TABLERO DE CIRCUITOS IMPRESOS EN DOS ZONAS, UNA PRIMERA ZONA (8) QUE TIENE FUENTES DE ENERGIA ELECTROMAGNETICA NO DESEADA Y UNA SEGUNDA ZONA (8'') CONECTADA ELECTRICAMENTE A LA PRIMERA ZONA A TRAVES DE UNOS CONDUCTORES (12), CUYA SEGUNDA ZONA PERMITE UNA CONEXION ADECUADA A OTROS DISPOSITIVOS. HAY INCORPORADO UN ELEMENTO FILTRANTE (13, 14) EN EL TABLERO DE CIRCUITOS IMPRESOS JUNTO CON UNAS ZONAS CONDUCTORAS INTEGRADAS (17, 18) QUE PROPORCIONAN UNA CONEXIONES ADECUADAS (19, 20) A UNA CARCASA METALICA DE PROTECCION (9, 10) PARA ELIMINAR O ATENUAR LOS COMPONENTES DE UNA SEÑAL NO DESEADOS DE LAS SEÑALES TRANSMITIDAS DESDE LA PRIMERA ZONA (8) HASTA LA SEGUNDA ZONA (8'') A TRAVES DE LOS CONDUCTORES (12). LOS COMPONENTESDE LA CARCASA DE PROTECCION (9, 10) CUBREN AL MENOS PORCIONES DE LA PRIMERA ZONA (8) DEL TABLERO DE CIRCUITOS IMPRESOS PARA BLINDAR LAS EMISIONES ELECTROMAGNETICAS QUE SE ORIGINAN EN LA PRIMERA ZONA ANTEDICHA.
