    After an electron tube is exhausted and sealed, a base (18) is pushed into position on the stem (12) of the tube the space between the stem and the base, at least around one pin (14) of the tube destined to have high voltages applied to it, is filled with a sealing substance; and then the stem and the pins are heated until the sealing substance is at least partially cured by heat from the stem to form a dielectric material (32).

    The invention relates to methods for manufacturing electronic devices, and specifically to methods for connecting a socket to a vacuum electron tube. The purpose of the invention is to increase the electrical strength of a tube and reduce assembly time.
    Figures 1 and 2 schematically show the base and throat attached in accordance with the inventive method. Vacuum electronic tube; FIG. 3 is a curve of the temperature change between the base and the neck of the tube during electrical processing of the tube according to one of the specific treatment programs.
    The base 1 is connected to the neck 2 of the electron tube, which contains the pingee 3 with the glass plate and the sealed tube-shaped process 4, through the glass plate the electrically conducting pins 5, located around the circumference of the process 4, are passed.
    The base 1 comprises a cylindrical body 6 open at one end with a radial flange 7 having a recess for the sealant 8 and a shoulder. 9. The outer cylindrical surface of the housing 6 is provided with a number of longitudinal grooves 10 extending from the flange 7 to the opposite end of the housing 6.

    The flange 7 has a group of circumferentially arranged holes i for the pins 5 of the pingels 3. The cap 1 also has an elongated chamber 11 for accommodating one of the pins 5 operating at a much higher voltage than the others, and radial fins 12 for separating the other neighboring pins. pins.
    The method can be carried out as follows.
    The pins 5 of the pingee 3 are passed into the corresponding holes in the base 1 and the base is pressed by the flange 9 to the glass pinge 3. At this, the body 6 freely surrounds the appendix 4. Through the filling hole 13 in the body 6 into the space between the body 4 of the pinge and the shoulder 9 of the base A metered amount of a thermosetting liquid sealant 8, for example silicone rubber, is introduced. The sealant can cover either all pins 5, or only high-voltage pin 5 located in chamber 11 and two adjacent pins.
    Then the electron tube with the base is placed on the stand or conveyor for electric processing (aging, training) of the tube, so that, to prevent air bubbles near the pin, do not swing or move the base relative to the pins, connecting the pins of the tube to the source of electrical energy and performing the electrical treatment of the tube electrodes according to a predetermined frame. As a result of this treatment, the pins 5 of the pinge are heated, causing initiation of curing and at least partial curing of the sealant 8 between the base 1 and the pin 3 of the neck 2 of the tube. The treatment should be carried out with an electric current sufficient to raise the temperature in the space between the base and the neck of the tube — 200fc in 60–120 min, and this should occur

    curing the sealant layer around the pins to a thickness of at least 0.15 mm.
    As an example illustrating the change in the temperature of the sealant in the space of one of the specific programs for electrical processing of a color kinescope, the curve in FIG. 3 is shown. The following main points and periods of the treatment program are indicated on this curve: A is the beginning of the electrical treatment at room temperature, AB is the activation of the cathode, BC is the period of switching on voltage only, CD is the period of switching on voltage of voltage and voltage Ge, DE is period knocking out the spot, EF is the period of undervoltage when the voltage is turned off when G is off, FG is the period of disconnection of all voltages, GH is the period of activation of undervoltage, HI is the period of disconnection of all voltages. Over the course of time CF, a rapid removal of sealant occurred.

    As a result of electrical treatment, the sealant becomes sufficiently viscous, which eliminates the formation of air bubbles near the pins of the electron tube. Invention Formula
