Abstract

La presente invención se refiere a un conjunto delantero para un tubo de rayos catódixos caracterizado porque incluye una placa delantera substancialmente plana que tiene sobre su superficie interna una pantalla fosforescente dispuesta centralmente rodeada por un área periférica sellante adaptada para acoplarse con un embudo, y un bastidor rígido por separado montado en la placa delantera que incluye un metal soldable y asegurado a la mencionada superficie interna entre la mencionada área sellante y la pantalla para soportar una máscara de sombra de lámina de tensión soldada en el mismo a una distancia predeterminada de la superficie interna de la placa delantera, la máscara tiene una área central provista de aberturas y un área periférica que está soldada al bastidor, la unión entre el bastidor y la placa delantera es de un área tal y de una resistencia tal como para resistir en forma substancial la totalidad de las fuerzas de presión ejercidas por la mencioanda máscara de lámina.The present invention relates to a front assembly for a cathode ray tube characterized in that it includes a substantially flat front plate having on its inner surface a centrally arranged phosphorescent screen surrounded by a sealing peripheral area adapted to engage with a funnel, and a frame separately rigid mounted on the front plate that includes a weldable metal and secured to the said inner surface between the said sealing area and the screen to support a tension foil shadow mask welded thereon at a predetermined distance from the inner surface of the front plate, the mask has a central area provided with openings and a peripheral area that is welded to the frame, the connection between the frame and the front plate is of such an area and of such resistance as to substantially resist the all the pressure forces exerted by the mentioned men reed plow.
