IN-TUBE RESISTOR AND CATHODE-RAY TUBE

摘要

PROBLEM TO BE SOLVED: To perfectly prevent destruction of an edge part of an electrode for a terminal by in-tube discharge and to avoid concentration of an electric field on the edge part of the electrode for a terminal. SOLUTION: A groove 37 is formed around the electrodes 30 for terminals on an insulation substrate 29 so as to surround the electrodes. A metal eyelet part 32 at one end of a terminal piece is inserted in a through-hole 31 formed at the center of the electrodes 30. A collar part 24 in contact with the electrodes 30 is formed around the eyelet part 32, and a bent part 40 bent with respect to the collar part 34 is formed in the periphery of the collar part 34. The bent part 40 is fitted into the groove 37. COPYRIGHT: (C)2005,JPO&NCIPI
