发明名称 ELECTRODE FRAME STRUCTURE OF CATHODE RAY TUBE ELECTRON GUN
摘要 PURPOSE:To easily and accurately mount a number of conductive elasticity support pieces on the fixed position by mounting them on the flange-shaped edge of an electron beam emitting final electrode whose part projects higher than the concentration magnetic pole bottom. CONSTITUTION:The conical concentration magnetic pole 30 with its bottom which has electron beam passing holes on the bottom is provided on the flange-shaped edge 2 of the electron beam emitting final electrode (G4 electrode) 20 which constitutes an electron gun. The flange-shaped edge 20A of the electrode 20 is formed so as to project outside the bottom of the magnetic pole 30. The hole 20D for inserting and fixing the lower projection end 40C of the elasticity support piece 40 is perforated to transmit anode voltage from the conductive film coated on the inside of the CRT to the electrode 20. After the magnetic pole 30 is fixed to the electrode 20 and the projection end 40C of the elasticity support piece 40 is inserted into the flange-shaped edge hole 20, the mounting section 40B of the elasticity support 40 is welded and fixed to the side of the magnetic pole 30.
