Definitions

  • the unit is to be fixed to the tube in the position achieved. According to the prior art, this is done either by turning screws which are mounted in a holding part until they rest against the tube cone, or by pushing wedges between said holding part 1 and the tube cone. With both types of attachment, it has been found that it is difficult to carry out the fixing so that the set position of the deflection unit is retained. It should be noted that the deflection unit, like the picture tube, is firmly held within the alignment device. If an operator now turns one of the screws mentioned more tightly than the others, the holding part warps a little. Accordingly, an elastic force builds up, which relaxes when the tube with the fixed deflection unit is removed from the alignment device. The same happens when one of the fixing wedges is pressed more firmly between the cone and the holding part than the others.
  • each support element is guided in a bearing in the bearing direction and can be locked in this bearing position in several positions.
  • Such a support device is particularly suitable for the adjusted holding of a deflection unit, but can also be used for the adjusted holding, e.g. B. a magnetic multipole unit can be used.
  • the support element is a pin which is guided in a bearing aligned with the picture tube and can be glued in any position in the bore. If this pin is moved so far after reaching the desired orientation that it comes into contact with the picture tube, the pressing force on the pin has no influence on the holding part of the deflection unit, since the pin can be moved freely in the bore in the holding part. Only when the pin is glued in the hole can it transmit a force between the picture tube and the deflection unit. However, if the pin is essentially inelastic, no adjustment force occurs even after it has been glued.
  • the clamping force when using an elastic pin depends solely on the pressing force used, provided that there is no very great friction between the pin and the bore. The latter can be easily prevented, however, since it does not matter in the least on the appropriate guidance of the pin in the bore.
  • Each support foot 15 has a guide bore 16 (FIG. 4) with a pin 17 mounted therein.
  • Each pin 17 acts as a support element for supporting the deflection unit 10 on the cone 18.K of the tube.
  • the deflection unit is fastened to the tube neck 18.H with the aid of the clamping ring 12.
  • each pin 17 can be pushed back and forth as desired in the associated guide bore, that is to say pushed in particular up to the bearing on the tube cone 18.K. If the pin 17 is rotated by 90 °, the partial thread 19 cuts into the non-recessed parts of the wall of the guide bore 16. As a result, the pin 17 is fixed in the guide bore 16 and at the same time it becomes a small distance depending on the direction of rotation, the angle of rotation and the thread pitch shifted.
  • the deflection unit is pushed in a conventional manner over the picture tube neck 18.H and then fastened to the tube neck in a fixed longitudinal position by tightening a clamping screw 22 on the clamping ring 12. Then the tube and the deflection unit 10 are contacted and in the operation of these parts the deflection unit 10 is adjusted with the aid of an adjusting device until imaging properties are within predetermined tolerances.
  • the deflection unit 10 must be fixed in the aligned position. This is where the described pins 17 begin to be used. These are namely in the position shown in FIG. 4A except for the Tube cone 18.K pushed.
  • the pins 17 shown in FIGS. 1-3 carry a widened head with a slot 24 for rotation. However, there must be no widened head and instead of a slot, e.g. B. an outer or inner polygon. Furthermore, the pin can be modified so that 19 more or less partial threads are present instead of two partial threads. If there is only a partial thread, there is the advantage that when fixing z. B. can be rotated by 270 ° to thereby achieve a particularly large fixing voltage, if this should be necessary.
  • the pin 17.5 and the guide bore 16.5 according to FIG. 5 have catches 25.17 and 25.16, respectively, which are aligned in such a way that they allow the pin 17 to be displaced in the direction of the picture tube cone 18.K.
  • the pin 17.5 has a rubber cap at its front end. The pin is used when fixing the deflection unit specified force pressed against the tube cone. The rubber cap 26 is slightly compressed. The longitudinal displacement position of the pin 17.5 in the guide bore 16.5 is determined by the detent achieved in each case. If the deflection unit is released by the alignment device, the elastic deformation force of the rubber cap 26 has the effect that the deflection unit is braced against the tube with a predetermined force.
  • a pin 17.6 with grooves 27 is present.
  • the associated guide bore 16.6 has an adhesive channel 28 for gluing the grooved pin 17.6 when it is displaced up to the picture tube cone.
  • the grooved pin 17.6 also has a rubber cap 26 at its front end for the purpose explained above.
  • the exemplary embodiments relate to configurations of guide bores and pins which are adapted to one another in such a way that the pins can be displaced in the guide bore without great force, but can be fixed relative to the guide in a plurality of displacement positions, preferably in any displacement position.
  • Combinations of guides and pins with these properties can be produced in many other embodiments, e.g. B. also in dowel-like embodiments, d. H. with arrangements in which a wedge is driven into the pin after its advancement to the tube cone in order to expand the pin and thereby jam it in the guide.
  • the pin is advantageously slotted for such a purpose.
  • the pins according to the exemplary embodiments are further designed such that a predetermined voltage between the deflection unit and the tube cone can be achieved with them.
  • a tension of a predetermined size can, however, also be realized in that the support feet 15 are given a predetermined by the alignment device Force is withdrawn while the pins are being advanced to and attached to the tube. After the deflection unit has been released by the alignment arrangement, the elastic restoring force of the support feet 15 provides the desired clamping force. It is pointed out that there are not necessarily three support feet 15 in the deflection unit, but that it can also be a different number.
  • the exemplary embodiment relates exclusively to a deflection unit.
  • Pins that can be moved and locked in the manner described can also be used to hold other components in an adjusted position, e.g. B. for magnetic multi-poles, as used for setting z. B. serve convergence and color purity.
  • the pins can be supported on the tube neck or on the deflection unit in front of it.
