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 color picture tube with such a holder of its mask, which allows easy insertion and removal of the mask during the manufacture of the color picture tube and which does not exert any knock-out forces when subjected to external forces.
  • Fig. 1 only the screen trough 1 with the mask 2 inserted 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 wear the mask 2 via holding members 6. The holding members 6 engage on the edge 7 of the mask 2.
  • the axis of symmetry of the color tube stands at the intersection of the x-axis with the y-axis perpendicular to the plane of the drawing.
  • the mask 2 does not have to be held in the corners of the shield trough 1, but can also be provided at the intersections of the x and y axes with the edge 7 of the mask 2 and the edge 4 of the shield trough 1.
  • FIG. 2 The side view of a holding part for the mask 2, in the direction of the arrow P 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 tube axis.
  • the free end of the pin 5 carries the two-part holding member 6, which is connected to the edge 7 of the mask 2 on the outside via a corner reinforcement 8.
  • the holding member 6 is oriented so that it is perpendicular to the electron 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. At the end of the bracket 9, which is supported on the pin 5, there is an approximately V-shaped curve Locking spring 11 attached, the free end of which holds the link 6 resiliently presses on the pin 5.
  • the bracket 9 is placed on the conical part 13 of the pin 5.
  • the securing spring 11 is fastened, which runs in an arc to a point of the holding angle 9 which lies above the conical part 13.
  • the securing spring is supported on the part of the spherical end 12 pointing towards the constriction 14 and thus presses the bracket 9 onto the conical part 13.
  • the holding member 6 is secured on the spherical end 12 of the pin 5 against slipping.
  • the free end 16 of the securing spring 11 runs out in an arc 17 which is directed towards the holding link.
  • the arch 17 At the apex of the arch 17 there are bulges 18 available, so that only small contact surfaces arise.
  • the forces exerted by the locking spring 11 via the bulges 18 on the holding member 6 run in the direction of the arrow K toward the center of the spherical end 12 of the pin 5.
  • the section shown in FIG. 4 along the line AB in FIG. 3 shows the parts of the holding bracket 9 and the securing spring 11 seated on the pin 5.
  • the holding bracket 9 and the securing spring 11 are both provided with a central incision, so that they each end in two prongs 19 and 20 respectively.
  • the tines 19 and 20 are connected to one another, for example, by welding spots 21.
  • the width of the incision in the securing spring 11 is chosen so that it is larger than the diameter of the constriction 14 but smaller than the diameter of the spherical end 12 of the pin 5.
  • the width of the incision in the holding angle 9 is selected such that it is larger than the diameter of the constriction 14 but smaller than the larger diameter of the conical part 13.
  • the bracket with the locking spring can be placed on the conical part 13 of the pin 5 from above.
  • the holding bracket 9 is then pressed against the widening end of the conical part 13 and thereby secured in this position.
  • the arc 17 of the locking spring 11 is also provided with a central cut, so that the locking spring 11 ends here in two prongs. As a result, the locking spring 11 presses on symmetrically the HALTEgLIED 6.
  • the incision in the holding angle 9 can be seen.
  • the incision is larger at the edge of the bracket than further inside and ends in a circular cutout. It is hereby achieved that the holding angle 9 encompasses the conical part 13 of the pin 5 on as large a part of the circumference as possible. As a result, the bracket 9 is secured in its final position against being pulled upwards.
  • FIG. 6 shows a side view of a second embodiment of the holding part.
  • the conical part 13 runs in the opposite direction than the pin described so far.
  • the thinner end of the cone-shaped part 13 now faces the melted-down end of the pin 5.
  • the locking spring 11 is now V-shaped and is attached at one end to the horizontally extending part of the holding bracket 9.
  • the other end of the locking spring runs out again in two prongs, in each of which a bulge 18 is present. These bulges 18 press resiliently against the holding member 6.
  • the pressing force is directed towards the center of the spherical end 12 of the pin.
  • the holding member consists of two parts, which are designated 6a and 6b.
  • Part 6a of the HaLtegLiedes includes the spherical end of the pin 5 and the part 6b of the holding member carry the corner reinforcement of the mask 2.
  • the part 6a is thicker and rigid, while the part 6b has resilient properties.
  • the parts 6a and 6b are connected to one another by spot welding.
  • FIG. 7 shows the section along the line A-A in FIG. 6. From this it can be seen that the holding member 6 has a trapezoidal shape; one end faces the pin 5 and the base side to the corner reinforcement 8.
  • the upper piece of the holding member is formed by the part 6a and the lower piece is formed by the part 6b.
  • the triangular hole 23 is present near the upper edge of part 6a. Due to the triangular shape of the hole 23, this lies only at three points on the spherical end 12 of the pin 5.
  • the corner reinforcement 8, which supports the mask 2 is fastened to the lower, resilient part 6b.
  • a recess 24 is provided in part 6b and in the associated part of corner reinforcement 8 so that the electron beam is not shadowed when it is deflected into the corner in question.
  • the mask can be provided with an inside corner reinforcement and the holding part attached to it.
