Abstract

Se describe un yugo de deflexion para tubos de rayos catodicos con una correccion de geometria de norte/sur que comprende un par de espirales (3) de deflexion horizontal y un par de espirales (4) de deflexion vertical, los dos pares que se aislan entre si por un separador (2), un anillo (5) de ferrita que cubre al menos parcialmente las espirales de deflexion y que tiene una parte frontal ensanchada, el yugo de deflexion que comprende en su region frontal al menos un par de medios magneticos para modificar localmente el campo magnetico en la region frontal y para corregir la geometria de la imagen creada en la pantalla del tubo, los medios magneticos se colocan en el espacio de una manera tal, que, para un plano (P) que contiene el eje longitudinal (Z) del yugo de deflexion y el eje de simetria (Y) de un medio magnetico, y para el punto M del plano (P) que corresponde al punto de coordenadas minimas de los medios, la interseccion del anillo con (P) es al menos parcialmente en su parte frontal, localizado fuera de la region delimitada por la linea media (D1) que pasan a traves de M y es perpendicular a Z, y la linea media (D2) que pasa a traves de M y que hace un angulo de 45 degree con (D1).
