Abstract

UN TECLADO PARA UN ORDENADOR QUE SEGUN UNA ESTRUCTURA PREFERENTE TIENE MULTIPLES TECLAS NO CONDUCTORAS Y AL MENOS UNA TECLA CONDUCTORA MONTADA EN UN RECEPTACULO DEL TECLADO. LA TECLA CONDUCTORA INCLUYE UN CUERPO DE LA TECLA DE PLASTICO MOLDEADO QUE TIENE UN MATERIAL CONDUCTOR EMBEBIDO EN EL MISMO. HAY UNAS CLAVIJAS CONDUCTORAS CONECTADAS ELECTRICAMENTE Y MONTADAS EN EL CUERPO DE LA TECLA CONDUCTORA. HAY UNA ALMOHADILLA DE DESCARGA ELECTROSTATICA DISPUESTA SOBRE UN CONJUNTO DE CONMUTACION QUE HAY POR DEBAJO DE LAS TECLAS DEL TECLADO. LA ALMOHADILLA DE DESCARGA SE ACOPLA A TIERRA A TRAVES DE UN RESISTOR CIRCUITAL. CUANDO SE PULSA EL CUERPO DE LA TECLA CONDUCTORA A UNA POSICION ACTIVADA, LAS CLAVIJAS SE ENGANCHAN A LAS ALMOHADILLAS DE DESCARGA ELECTROSTATICA DE MODO QUE LAS CARGAS ELECTROSTATICAS DEL USUARIO SE DISIPEN PROGRESIVAMENTE A TIERRA A TRAVES DEL CUERPO DE LA TECLA, LA CLAVIJA, LA ALMOHADILLA DE DESCARGA Y EL RESISTOR CIRCUITAL. AL MENOS UNO DE LOS RESISTORES CIRCUITALES O DE LAS CLAVIJAS TIENE UNA RESISTENCIA MAYOR A LA RESISTENCIA DEL CUERPO DE LA TECLA CONDUCTORA. DE ESTE MODO, LA CARGA ELECTROSTATICA SE DISIPA DE FORMA RUTINARIA DEL USUARIO DEL ORDENADOR AL TIEMPO QUE ASEGURA QUE EL USUARIO NO SUFRE UNA DESCARGA CUANDO TOCA POR PRIMERA VEZ Y ACCIONA LA TECLA CONDUCTORA.
