    摘要: A Focusing electrode in an electron gun for a color cathode ray tube provides a higher degree of freedom in electron gun design and reduces errors during assembly of the electron gun. A first focusing electrode that receives a constant voltage has vertically elongated electron beam pass-through holes formed in it. A second focusing electrode that receives a dynamic voltage has electron beam pass-through holes that include a pair of burring parts formed on their upper and lower edges. The burring parts are disposed in each of the vertically elongated electron beam pass-through holes in the first focusing electrode without changing a horizontal diameter of the electron beam pass-through holes in the first focusing electrode.
