    The base comprises a tubular housing adapted to fit over the exhaust tubulation of an electron tube stem, and a wafer flange extending outwardly from the open end thereof. The flange is apertured to receive an array of conductors of the stem. A recess is provided in the wafer flange facing the stem and a passageway communicating therewith is provided through the base separate from the housing cavity for the purpose of injecting a dielectric material into the recess around some of the stem conductors. The passageway may, e.g., be through the flange or in the housing wall.

    one
    This invention relates to the production of electron beam tubes (CRT), in particular to CRT caps.
    The known base of a CRT containing a cylindrical body, openings for inlets, a CRT and openings for the springing pin) 1.
    The disadvantage of this base is the complexity of its installation on the neck of a CRT.
    The base of the electron tube is known, comprising a tubular body made from an open end to accommodate the deflected pinge of the lamp, a flange on the open end, holes arranged around the circumference to accommodate the lamp inlets, a recess in the flange 2.
    The disadvantage of this basement is that, when mounted on a CRT, a mastic of dielectric material is applied to the CRT in the flange, after which the basement is put on the release pin. As a result of the fact that the mastic is put into contact, prior to the installation of the plinth on the unclamped pinge, contamination occurs. Since the free volume between the tube and the base is not the same for different tubes, it is difficult to determine the amount of mastic injected, which complicates the process.
    Another disadvantage of the known plinth is its bias when mounted on
    tube arising from the presence in the welding spot legs schva. In addition, the gap between the base and the tube causes leakage of the plastics mastic inserted into the base.
    The aim of the invention is to facilitate the insertion of a dielectric material into a recess in the flange.
    The goal is achieved by the fact that in the base of the electron tube containing
    a tubular body made with an open end to accommodate the detached lamp hinge, a flange at the open end, holes arranged around the circumference to accommodate the lamp inlets, a recess in the flange, the base has a channel extending in the wall of the tubular body and connected to a recess in the flange.
    In the proposed base, the recess in the flange is divided by a protrusion into two sections, and the channel at the point of entry of the dielectric material, mastic, is offset to the axis of the tubular body.
    FIG. I shows the base, side view, with a partial cut; in fig. 2 - the bottom view; in fig. 3 - the same, top view; on fng. 4, 5 - discharge of a modified base; in fig. 6 is a section A-A of FIG. 2; in fig. 7 and 8 - modified base, top view; in fig. 9 - section bb FIG. 2; in fig. 10 is a sectional view BB of FIG. 2; in fig. 11 is a sectional view of the FIG. 2; in fig. 12 - modified base, general view.
    The neck of the SLT 1 (Fig. 1) has a leg 2 containing a series of rigid conductors or bushings 3. The bushings 3 are hollowed into the leg 2 and pass through it along the ring parallel to each other. Leg 2 has an otted out shtengel 4 located in the center of the ring of bushings 3. The socle 5 is attached to the end of leg 2.
    The base 5 comprises a cylindrical body 6 with a hole 7 and a flange 8. The body 6 is freely mounted on the pingee 4. The external surface of the body 6 has a series of longitudinal grooves 9 that extend from the flange. The flange 8 has holes 10. Inputs 3 pass through holes 10 and are located in grooves 9.
    The base 5 is provided with a tubular chamber 11 (FIG. 2) located along the body 6. On one side, the chamber is closed by a flange 8, on the other side it is open. In chamber I is located one of the inputs 3, to which a high voltage is applied. This camera is designed to improve the isolation of the high-voltage input, to any neighboring input.
    In order to increase the breakdown voltage between inputs, a radial edge 12 is provided between two adjacent inputs 3. The edge 12, although not as effective as chamber 11, is high enough for avoiding high voltage breakdown for lower voltages.
    The foot-contacting surface 13 (Fig. 3) of the flange 8 has a recess 14. The height of the recess 14 should be such that a thin layer of dielectric material is formed that will come in contact with several leads 3. This value is usually 2.5 mm. The recess 14 has a width sufficient to completely cover the high-voltage inlet 3 in the chamber 11 and the adjacent inlet located between the chamber 11 and the rib 12. Also provided are cavities 15 in the form of a rim near the inlets 3, so that the dielectric material introduced into the recess 14 also surrounds inputs in the place of their exit from a leg 2.
    In practice, a high voltage is not applied to all inputs and therefore there is no need to surround them with a dielectric material. It is recommended to introduce the dielectric material into the recess 14, it will not surround the high-voltage input 3 in the chamber 11 and the other input between the chamber 11 and the edge 12 and extend further through the recess 14 until half of the recess is filled.
    So that the dielectric material gets into the recess 14, a channel 16 is provided
    the wall of the housing 6, the socle 5 extending from the distal end and connecting with the recess 14. A dielectric material or mastic is introduced by means of a nozzle in the opposite end from the flange 8 of the socle 5. Since the channel 16 has the same volume in each socle, an exactly measured amount of mastic can be distributed into channel 16 and fill in the recess 14, flow into body 6 around the stem
    4. Thus, regardless of the volume
    the recess 14 is filled without
    risk of leakage to the base 5, as a result
    what causes smudges.
    To ensure complete coverage
    the parts of the recess 14 near the high-voltage input, the recess is divided into two parts.
    One part 17 has an arcuate shape and covers a high-voltage input, channel 16 and adjacent input between the chamber 11
    and rib 12. The other part is a continuation of the recess 18. The recess in the flange is separated by a protrusion 19. When the dielectric material is introduced into the recess 14 through the channel 16, it first enters section 17 and fills it, rather than pouring over the projection 19 into the second section 18. This ensures coverage of the two inputs in section 17, where insulation from the high-voltage breakdown is most important.
    Various channel shapes may be provided, for example, as shown in FIG. 4. In this modification, the basement of the channel 16 has two sections. One portion of the channel 20 is connected to a recess 14 in the flange 8
    a plinth 5, and another section of the channel 21, which deflects towards the axis of the socle 5 and is somewhat larger compared to the first section of the channel. Due to this channel displacement, the force of the injector applied to the base, to a lesser extent
    tends to turn the base on the leg 2.
    The expansion of the channel 21 facilitates
    the introduction of a dielectric material.
    Another channel option is possible for
    filling (see fig. 5). The portion of the channel 21 is located coaxially with the base 5. With the help of this base, the loading of the dielectric material can be performed by means of a piston 22 with a rubber ring 23, which forces mastic in the channel.
    Since there is a seam in the place of welding of the CRT tokens with a bulb, which, when installed, can cause its distortion, a protrusion 24 is provided on the base (Fig. 6). The seam on the tube is compensated by a protrusion 24 having a height of about 0.75 mm.
    In order for the mastic to flood the high-voltage input, a portion of the projection 24 may
    cut near this pin or bend
    him (see Fig. 7 and 8). Due to this, the dielectric material flows around the high-voltage pin 25 better (Fig. 7). The protrusion 24 has an arcuate portion 26 (FIG. 8), which also allows the mastic to flow around the high-voltage output better.
    A deep hole 27 is provided in the housing 6 (FIG. 9). It serves to use the proposed base for universal type CRT legs, having a certain number of terminals 3.
    Input 3 can also be located in channel 16. At the same time, channel 16 is located in accordance with the position of the input in the flange.
    FIG. Figure 12 shows the base used when the high voltage applied to a CRT is not so large.
    The use of the proposed plinth simplifies the technological process of socle, increases the electrical strength.
