Abstract

Un disco de soporte (10) de metal, para un sello de celda electroquímica, ejerce una fuerza resiliente radial hacia afuera contra el sello, para mantener la integridad del sello en un amplio intervalo de temperaturas de operacion y, al mismo tiempo, ejerce una fuerza hacia arriba contra el fondo de la terminal de tapa de extremo de metal de la celda, para asegurar el contacto eléctrico entre el ánodo dentro de la celda y la terminal. El disco incluye una plataforma (14) central, circular, conectada a un reborde sellador (28) del borde de sellado externo, por un elemento anular de flexion, la cual permite el movimiento radialmente al interior y al exterior del borde sellador (30), cuando el extremo de la celda se ondula radialmente, durante el proceso sellador. El ondulado también mueve la porcion central (12) del disco hacia arriba, lo cual resulta en una fuerza ascendente ejercida contra la terminal de extremo. El elemento de flexion es una serie de tres nervaduras anulares, curvadas, con la primera (20) y la tercera (26) curvadas hacia abajo y la segunda (24) curvada hacia arriba. un anillo (22) que depende radialmente hacia afuera y en un ángulo hacia arriba desde la primera nervadura, conecta esta primera nervadura a la segunda nervadura y ayuda a impedir la deformacion plástica del sellado de disco.
