Definitions

  • the invention relates to a color picture tube according to the preamble of claim 1.
  • the invention has for its object to provide a simpler securing the holding members on the pins for such a color picture tube.
  • Fig. 1 only the screen trough 1 with the shadow mask 2 is shown from a conventional color picture tube.
  • the x-axis, the y-axis and the diagonals D1 and D2 are shown in this representation.
  • the fritting surface on the edge 4 of the screen trough 1 is labeled 3.
  • the screen trough 1 carries the luminescent layer, not shown, on its inside.
  • pins 5 are arranged which support the shadow mask 2 via holding members 6.
  • the holding members 6 engage on the edge 7 of the shadow mask 2.
  • the axis of symmetry of the color picture tube is perpendicular to the plane of the drawing at the intersection of the x-axis with the y-axis.
  • the shadow mask does not have to be held in the corners of the screen trough 1, but can also be provided at the intersections of the x and y axes with the edge 7 of the shadow mask 2 and the edge 4 of the screen trough 1.
  • FIG. 2 A section through the lower left corner of the screen trough 1 in FIG. 1 is shown in FIG. 2.
  • the pin 5 is melted at one end.
  • the pin 5 is inserted into the edge 4 so that it is perpendicular to the axis of symmetry of the color picture tube.
  • a different orientation of the pins is also possible.
  • the free end of the pin 5 carries the two-part holding member 6, which is connected to the edge 7 of the shadow mask 2 on the outside via a corner reinforcement 8.
  • the holding member 6 is aligned so that it is perpendicular to the electrode beam E directed into this corner.
  • the pin 5 also carries a bracket 9, at the free end of which the magnetic shield 10 of the color picture tube is attached.
  • a securing element 11 is introduced, which presses the free end of the holding member 6 onto the pin 5.
  • the holding member 6 On the spherical end 12 is the holding member 6, which is held in place by the securing element 11.
  • Other designs of the free ends of the pins are also possible, e.g. a conical shape.
  • the securing element 11 consists in this embodiment example of a cap screw 11.1.
  • This cap screw 11.1 is screwed into a threaded blind hole 15 in the free end of the pin 5.
  • the edge of the head of the cap screw 11.1 comes into contact with the holding member 6 and presses it onto the spherical end 12 of the pin 5.
  • This edge of the cap screw is chamfered at such an angle that the resulting surface 17 runs parallel to the surface of the holding member 6 .
  • the second exemplary embodiment for the securing element 11 shown in FIG. 4 consists of a notch nail 11.2.
  • the notch 11.2 is pressed into a blind hole 16 present in the free end 12 of the pin 5.
  • the head of the notch nail 11.2 presses on the holding member 6 and holds it on the spherical end 12 of the pin 5.
  • the edge of the head of the notch nail 11.2 in contact with the holding member 6 is chamfered at such an angle that the resulting surface 17 is parallel runs to the surface of the holding member 6.
  • the securing element 11 ensures simple and inexpensive securing of the holding members against unhooking. This type of protection is less susceptible to overload than safety springs. The pressure forces generated also show smaller fluctuations in comparison with one another.
