Abstract:
An auxiliary coil for a deflection yoke of a Braun tube having a horizontal deflection coil for horizontally deflecting electron beams radiated from an electron gun, a vertical deflection coil for vertically deflecting the electron beams, and a holder inserted between the horizontal and the vertical deflection coils for mechanically fixing them and electrically insulating them, the auxiliary coil comprising:a first deflection portion coil extending from a â€˜3-o'clockâ€™ position on a neck side of the Braun tube to a â€˜3-o'clockâ€™ position on a screen side of the Braun tube relative to a long dimension of the deflection yoke; a first flange portion extending a predetermined length from the â€˜3-o'clockâ€™ position on the screen side to a â€˜12-o'clockâ€™ position on the screen side; a second deflection portion extending a predetermined length from the â€˜12-o'clockâ€™ position on the screen side to the â€˜12-o'clockâ€™ position on the neck side; a second flange portion extending a predetermined length from the â€˜12-o'clockâ€™ position on the neck side to a â€˜9-o'clockâ€™ position on the neck side; a third deflection portion extending a predetermined length from the â€˜9-o'clockâ€™ position on the neck side to a â€˜9-o'clockâ€™ position on the screen side; a third flange portion extending from the â€˜9-o'clockâ€™ position on the screen side to a â€˜6-o'clockâ€™ position on the screen side; a fourth deflection portion extending a predetermined length from the â€˜6-o'clockâ€™ position on the screen side to a â€˜6-o'clockâ€™ position on the neck side; and a fourth flange extending from the â€˜6-o'clockâ€™ position on the neck side to a â€˜3-o'clockâ€™ position on the neck side.
