Title:
LEAD FRAME FOR FLUORESCENT DISPLAY TUBE
Document Type and Number:
Japanese Patent JP3156910
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lead frame having excellent workability, high accuracy and high profitability by connecting an anode lead part which is provided with anode leads respectively having an engagement part, and a cathode lead frame with a cathode lead part made of the material different from the material of the anode lead part.
SOLUTION: A first engagement part 13 is provided in both ends of a frame 11 of an anode lead part 10, which is provided with multiple leads 12 in the vertical direction from the anode lead frame 11, and each first engagement part 13 is engaged with each engagement part 23 of a cathode filament 21 forming a cathode part 20 made of the material different from the material of the lead part 10. This filament 21 and a cathode frame 22 are similarly connected to each other, and a lead frame for fluorescent display tube having the excellent workability, high accuracy and high profitability without the necessity of etching and stamping is thereby obtained.
