Definitions

  • the invention relates to a picture tube socket according to the preamble of claim 1.
  • a picture tube socket - sometimes also called a picture tube connection base - is used to produce the electrical connections for the picture tube.
  • the picture tube holder has several contact springs in a contact spring chamber, and when the picture tube holder is pushed onto the end of the picture tube, the pins of the picture tube located there come into contact with the contact springs.
  • the picture tube holder itself is located on or on a picture tube connection plate, which is a small printed circuit board which, in addition to the picture tube holder, also carries electrical (protective) resistors and often also the video output stage.
  • a focus voltage and a screen grid voltage are required for the operation of the picture tube.
  • the latter defines the operating point of the picture tube, while the focus voltage is responsible for the focusing of the electron beam and thus for the image sharpness.
  • the location of the focus voltage regulator (or double regulator) within the television chassis is important in the manufacture of televisions from the perspective of their final adjustment. In order to be able to make the necessary settings, the focus voltage regulator must be easily accessible from the outside. This requirement is to be made above all if the final setting is not manual, but automatic (robot setting).
  • the desired accessibility of the focus voltage regulator can be achieved relatively easily with television sets with a relatively large chassis, but the tendency generally leads to increasingly compact structures with less and less space requirement for the chassis.
  • the individual components are arranged in such a way that unimpeded access to the focus voltage regulator from the outside is not readily possible.
  • the possible measure of not locating the focus voltage regulator locally on the high-voltage transformer, but at another location on the chassis cannot always lead to the goal in very compact structures, especially since the focus voltage regulator cannot be arranged anywhere due to the high voltage.
  • the invention provides a remedy for a picture tube holder according to the preamble of claim 1 in that the focus voltage regulator is arranged within the focus chamber.
  • a picture tube connecting plate is known per se, on which on the one hand a picture tube base and on the other hand a focus voltage regulator are arranged.
  • This new and surprising measure which can be implemented in a simple manner, makes it possible to provide the focus voltage regulator as an integrated component of the picture tube holder. This offers significant advantages.
  • the picture tube holder forms a component that is easily accessible from the outside, which means that the required final setting after the manufacture of the television sets can be carried out without any problems. It is also easily possible to use an automatic end setting, as the picture tube holder - as mentioned - remains accessible even with compact structures.
  • the local position of the focus voltage regulator as an integral part of the picture tube holder can be regarded as ideal, since the focus voltage is now set directly at the point where the electrical contact with the picture tube is made via the associated contact spring.
  • the focus voltage regulator can now be easily arranged within the focus chamber of the picture tube holder.
  • the outer dimensions of the picture tube holder can remain unchanged, i.e. the measure according to the invention does not require any additional space. Rather, the space elsewhere, where the focus voltage regulator is usually located, is saved.
  • the focus voltage regulator comprises a rotary knob which, according to an advantageous development of the invention, is held in an opening in the chamber wall of the focus chamber, so that the required adjustment can be made from the outside.
  • the high voltage, from which the focus voltage is tapped, is fed through a further opening in the chamber wall of the focus chamber.
  • the picture tube socket is often located on a circuit board, and this can easily be located at the location of the opening for the rotary knob in the chamber wall dung is also provided with an opening so that the focus voltage regulator remains accessible for the final setting in this case as well.
  • an expedient embodiment of the invention provides for the use of a series resistor, so that the focus voltage is attacked on a series circuit comprising the series resistor and the focus voltage regulator.
  • the focus voltage regulator can be made relatively small, so that it can be accommodated within the focus chamber in any case.
  • the series resistor mentioned can be accommodated within a pocket provided on the side of the focus chamber.
  • the picture tube holder 10 also has a coding 16 in the form of a Incision.
  • a center line 22 indicates that the picture tube holder 10 is composed of an upper and a lower half and is welded in the area of the center line 22, for example by ultrasound.
  • the entire picture tube holder 10 consists of a plastic, three ribs 25 (cf. FIG. 2) being provided on the chamber floor 24 for reasons of injection technology.
  • a focus voltage regulator 48 (cf. FIGS. 4-6) is arranged within the focus chamber 14. This comprises, in a manner known per se, a substrate 32 which carries a resistance track on the lower side (FIG. 3).
  • the focus voltage regulator also includes a rotary knob 44 with a slip ring 42 for the resistance track.
  • Such focus voltage regulators are known per se, so that no further explanations are required at this point.
  • the substrate 32 is held within the focus chamber 14 by locking lugs 30 in connection with a support 28.
  • a support 28 In the lower chamber wall of the focus chamber 14 there is an opening 26 in which the rotary knob 44 is mounted and held, the rotary knob 44 being accessible from outside the focus chamber 14 in order to actuate the focus voltage regulator or to be able to adjust the focus voltage.
  • the side of the focus chamber 14 is the pocket 20 for receiving a series resistor 46, which is formed by a resistance track on a substrate.
  • This series resistor 46 is electrically connected to the focus voltage regulator, as will be explained below with reference to FIGS. 4-6.
  • This spark gap is produced between a focus electrode 34 electrically connected to the focus contact spring - that is to say with the focus voltage - and a spark electrode 40 connected to ground.
  • the focus electrode 34 can be arranged on the upper side of the substrate 32, so that the desired spark gap is retained in the new picture tube holder 10, although the focus chamber 14 also receives the focus voltage regulator.
  • a high-voltage transformer 50 - here a diode-split transformer (DST) - which supplies a high voltage U H is indicated by the dashed outline in the left half of the figure. In the right half of the picture, it is also indicated by dashed lines that the focus voltage regulator 48 is located within the picture tube holder 10.
  • DST diode-split transformer
  • a resistor 52 is connected to the high voltage U H , from which the high-voltage line 54 leads to the picture tube holder 10, and from there via the series resistor 46 to the focus voltage regulator 48.
  • the desired focus voltage U F can be selected by setting the focus voltage regulator 48.
  • the focus voltage regulator 48 would then have to cover a larger voltage range and would therefore have to be made larger in volume.
  • the regulating range of the focus voltage regulator 48 can be dimensioned by the series resistor 46 in such a way that the focus voltage regulator 48 has only relatively small dimensions and can be easily handled can be accommodated within the focus chamber 14.
  • FIG. 5 shows a solution comparable to FIG. 4, with the difference that here the focus voltage U F is tapped directly at the focus voltage regulator 48.
  • the series resistor 46 is, so to speak, connected in series with the resistor 52 on the high-voltage transformer 50, so that only the focus voltage regulator 48 needs to be arranged in the picture tube socket 10 in order to be able to set the focus voltage U F.
