Abstract

PURPOSE:To prevent a pipe discharge encountered at the time of switch-on-off by separating a clamping metal from earth and the covering the surface of the clamping metal with an insulation film. CONSTITUTION:The clamping metal 14 is separated from the earth, whereby the voltage of the point P1 approximates to the voltage of the anode 16, the potential difference between it and the end of the inside conductive film 4 becomes smaller, and creeping discharge becomes hard to occur. Also, the periphery of the clamping metal 14 is provided with the insulation film 30 prevent the occurrence of creeping discharge when the lead line or earth line of the deflecting yoke 12 comes near the clamping metal 14.
