TH9569A - How to make a downgraded explosion proof bar - Google Patents

Abstract

The diluted edge band for cathode ray tubes with arc angles is fixed diagonally 1.0% to 1.5% to form the cathode area in the band.

Claims (8)

1.How to make a downgraded explosion-proof bar before assembly Into a rectangular cathode ray tube with curved angles. It consists of a process of - creating at least one strip of material in a four shaped loop. A rectangle with curved corners and smaller dimensions than dimensions. Of such a cathode ray tube a little By connecting the ends of At least one of the strips together - fixing the loop along its own diagonal until Slightly beyond the limit on the elasticity of the loop material. In this way, it will enlarge the dimension of the diagonal line. The angle of the hoop is approximately 1.0% to 1.5% and makes There is a slight induced area of the loop. 2. Method according to claim 1, where the inner radius of the corner Of such a loop is equal to the outer radius of the angle of the tube. Such cathode rays 3. Method according to claim 1, where of the welding procedure This link includes joining the ends of the band together. 4. Method according to claim 1, where of the welding procedure This extension includes clamping the ends of the tabs together. 5. How to test the anti-explosion bar before assembling the loud strip? Mentioned to rectangular cathode ray tubes with curved angles. It consists of a process of - creating at least one strip of material in the shield. A rectangular explosion with curved corners. And have dimensions Smaller than the corresponding dimensions of the cathode ray tubes Slightly, by the way, the ends of the strips are connected, at least that One end of the bar joined together, in such a way it will cause a point. Connect the ends that are connected together - test the connection points by fastening the protective tabs along the Diagonal, holding to exceed the elastic limit of the material Used to make that protective bar a little, that way it would be The magnification of the diagonal of the protective bar is approximately 1.0% to 1.5%, and this causes a small portion of the Such protection tab 6. Method according to claim 5, where the inner radius of the corner Of such protective bar is the same size as the outer radius of the corner of the Such cathode ray tubes 7. Method according to claim 5, where of the welding procedure This link includes joining the ends of the band together. 8. Method according to claim 5, where of the welding procedure This extension includes clamping the ends of the tabs together.
