Abstract

En la presente invencion se proporciona un tubo de rayos catodicos. El tubo de rayos catodicos de acuerdo con la presente invencion incluye un panel que tiene una película fluorescente formada en la superficie interior del mismo, un montaje de estructura de máscara de sombra colocado dentro del panel, una embocadura a la cual se sella el panel y que tiene una cañon electronico instalado en una porcion de cuello de la misma y un yugo de desviacion instalado alrededor de una porcion conica de la misma, y una porcion protectora contra los campos magnéticos que se instala a lo largo de la pared de la embocadura e incluye una placa metálica para bloquear las influencias de los campos magnéticos terrestres. En el tubo de rayos catodicos de acuerdo con la presente invencion, es posible bloquear las influencias de los campos magnéticos terrestres con una porcion protectora contra los campos magnéticos que tiene una estructura simple.
