Definitions

  • the invention relates to grids of electron beam generation systems, such as those used in picture tubes of television sets.
  • Such grids which together with other components form the electron beam generation system of picture tubes in a defined number, have in common that they are shaped sheet metal stampings and that they have an opening for each electron beam source - the so-called cathode - through which those emitted by the cathode Electrons can pass through.
  • the size, shape and spacing of the openings from one another - the so-called s-spacing - can be chosen differently from grating to grating.
  • the openings of the grids are conventionally produced using stamping technology.
  • the invention has for its object to provide a grid that easily meets the highest dimensional accuracy requirements.
  • This object is achieved in that deep-drawn insertion sleeves are inserted into the openings of the grids and are firmly connected to the grille.
  • deep-drawn plug-in sleeves are particularly advantageous because deep-drawn sleeves can be produced in large numbers particularly inexpensively and with extremely high dimensional accuracy due to the radial arrangement in the areas in which the electrons enter the openings of the sleeves.
  • the length of the sleeve body of the insertion sleeve exceeds the thickness of the grid in the region of the opening, it is ensured that the electrons are guided particularly well on their way through the insertion sleeve.
  • the diameter of the openings in the grids is chosen to be larger than the outer diameter of the insertion sleeves, the insertion sleeves can be easily inserted into the grating and, moreover, aligned well with one another.
  • the collar attached to one end of the sleeve body and its special shape ensure that the electron beam guidance is further improved.
  • the extraordinarily good dimensional accuracy of the insertion sleeves is not impaired.
  • the grid constructed according to the invention not only meets the highest dimensional accuracy requirements, but can also be adapted very easily and without great effort to change the s-spacing due to the possibility of aligning the insertion sleeves in the openings of the grid.
  • FIG. 1 shows a grid 10 of an electron beam generation system using in-line technology.
  • the elongated sheet metal stamping body 11 of the lattice 10 which takes up a hat shape in plan view, has three circular openings 13.1, 13.2, 13.3 with a diameter D ö on its base 12.
  • Circular insert sleeves 14.2, 14.3 with an outer diameter D E are inserted into two of these openings 13.2, 13.3.
  • the insertion sleeve 14.2 is still unsecured in the opening 13.2 of the sheet metal stamping body 11, the insertion sleeve 14.3 is already connected to the bottom 12 of the sheet metal stamping body 11 via the laser welding points 15.
  • FIG. 2 shows a circular insertion sleeve 14.1 in detail.
  • sleeve body 16 which with its overall length L exceeds the thickness D of the sheet metal stamping body 11 in the region of the base 12, an outwardly curved collar 17 is arranged.
  • this collar 17 covers the diameter D O of the opening 13.1 in the bottom 12.
  • the transition from the collar 17 to the sleeve body 16 as well as the collar top 18 are rounded.
  • the openings 13.1, 13.2, 13.3 in the base 12 of the stamped metal body 11 can also be oval and the overall length L of the Sleeve body 16 can correspond to the thickness D of the stamped sheet metal body 11 in the region of the openings 13.1, 13.2, 13.3.
  • the connection of the insertion sleeve 13.1, 13.2, 13.3 to the bottom 12 of the sheet metal stamping body 11 can also take place on the side of the bottom 12 which faces away from the collar 17 of the insertion sleeve 13.1, 13.2, 13.3.
