Definitions

the invention relates to a picture tube holder with a contact spring chamber and a focus chamber connected to the contact spring for the focus voltage.
a picture tube socket - sometimes also called a picture tube connection base - to make 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.
Focus voltage and an S chirmgitterhard needed.
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.
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.
an expedient embodiment of the invention provides 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 in any case within the focus chamber.
the series resistor mentioned can be accommodated within a pocket provided on the side of the focus chamber.
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 region 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.
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.
FIG. 5 shows a solution comparable to that of FIG. 4, with the difference that here the focus voltage U F is tapped directly at the focus voltage regulator 48.
