    one
    The invention relates to electrovacuum engineering, namely, devices for mounting a deflection system of a cathode ray tube.
    A device for attaching a deflection system of a cathode-ray tube, including a platform for fastening to a tube, a housing for accommodating a deflecting system, and means for adjusting and securing the housing on the platform 1 are known.
    However, this device does not provide precise adjustment of the deflection system relative to the cathode ray tube. -
    A device for attaching a detachment system of a cathode ray tube is known, comprising an annular platform for attaching to the tube, an annular case for accommodating a deflecting system and means for adjusting and securing the case on the platform 2.
    The disadvantage of such a device is the difficulty of adjusting the position of the deflecting system relative to the cathode ray tube, which does not provide sufficient accuracy when adjusting.
    The aim of the invention is to simplify the adjustment of the position of the deflection system relative to a cathode ray tube.
    The goal is achieved by the fact that the means for adjusting and fixing the housing with the deflecting system on the platform are made in the form of springs attached to the platform or to the case and connected to the possibility of adjustment and fastening with protrusions made respectively on the case or platform. New springs are EXCELLENT either in the form of arcs attached to the platform or to the body with their ends and connected to the projections with its central part, or in the form of plates attached to the platform or to the body with one ends and projections with other ends. Moreover, the said means for adjusting and securing have four said springs and, accordingly, four protrusions arranged in parallel pairs on opposite sides relative to the axis of the device.
    FIG. I shows a cathode ray tube with a partial cut. And a device mounted on it for fastening a deflecting system; fig 2 is the same, another option; in fig. 3 is a plan view of the device for fastening the deflecting system shown in FIG. in fig. 4 is the same side projection; FIG. 5 is a device for attaching a deflecting CHCTeMtj shown in FIG. 2, a plan view; in fig. b - schematic drawing illustrating the action of arcuate springs, plan; The electron-beam tube consists of front glass 1, a cone part 2 and a neck 3. The internal surface 4 of the front glass 1 is covered with phosphors of three colors 5, consisting of parallel rows of different colors. The electronic projectors assembly 6 located in the neck 3 consists of three electronic projectors (not shown for each color of the phosphor in the drawing. The shadow mask 7 is installed near the inner surface 4 of the front glass 1. The shadow mask 7 for a tube with linear phosphors has surface of the slot in the form of slots. On the outer surface of the cathode-ray tube is installed a device 8 for fastening a deflecting system consisting of an annular platform 9 and an annular body 10. The platform 9 is attached to the outer The surface of the conical part 2, and the housing 10, shown together with the deflecting system 11, is located at the junction of the conical part 2 and the throat 3. The deflecting system 11 consists of two pairs of coils (not shown) creating magnetic fields for deflection of electron beams: The platform 9 (FIG. 3 and 4) consists of a short conical part 12, the shape of the inner surface of which corresponds to the shape of the outer surface of the conical part 2. The conical part 12 has four projections 13 with slits 14 for fastening the housing 10 which has even D sides to do a spring 15-18, attached his own. ends to the retaining ring 19 in pairs on opposite sides. On the retaining ring 19 there are four latches 20, with which the deflection system 11 snaps in and is secured. Each arcuate spring 15-1 has a small bracket 21 on the outside (optional). Between each taco bracket 21 and the corresponding arcuate spring 15-1B there are holes 22f into which the projections 13 of the mold 9 enter. On each side of the projections 13 there is a space that allows adjusting the position of these protrusions inside the slots 22 when the deflection system 11 is in position. The protrusion 13 is fixed in slots 22 by bolts 23, which ensures the necessary position of the housing 10 with the deflecting system 11. The projections 13 can also be glued in the slots 22 or welded using ultrasonic welding to permanently fix the deflection They can be made on the housing 10, then the arcuate springs 15-18 are made on the platform 9. The platform 9 (FIG. 5) consists of a ring 24, the shape of the inner surface of which corresponds to the shape of the outer surface of the conical part of the 2-beam radiation tube, Four cantilever leaf spring 25 mounted on the pins 26 tangentially relative to the outer surface of the ring 24 and directed clockwise. The bent ends 27 of the springs 25 are welded to the pins 26 and the ring 24, which provides rigidity for attaching the springs 25. Each spring 25 has an open slot that extends longitudinally along the spring 25 and serves to fasten the housing 10 to the springs 25 with bolts 28. Console leaf spring 25 can be directed counterclockwise. The pins 26 have central holes 29, which extend to the inner surface of the platform 9 and serve to introduce adhesive material in order to secure the platform 9 to the conical part 2 of the tube. The four protrusions 30 are located around the periphery of the housing 10 and serve to connect to the four springs 25 with the aid of bolts 28. The leaf springs 25 can also be fixed to the housing 10, then the protrusions 30 should be located on the platform 9. The device works as follows. The tube 9 is glued to the tapered portion 2 of the platform in a position that allows the housing 10 to move while adjusting the position of the deflecting system 11, which is installed into the housing 10 separately and secured with the latches 20. Thereafter, bolts 23 or the like bolts 28 and do not tighten. Then the housing 10 with the deflecting system 11 is installed on the platform 9, so that the bolts 23 and 28 fit into the slots 14 or into the open slots of the springs 25. The electron-receiving tube and the deflection system 11 are turned on, after which the housing 10 is moved so that the deflecting system 11 occupied the desired position relative to the electron beams of the tube. After the required position has been reached by the deflecting system 11, the bolts 23 and 28 are tightened and, if necessary,
    springs 15-18 and springs 25 may be ultrasonic welded or glued.
    It should be noted that the adjustment with the help of springs 25 provides great opportunities for moving the deflecting system 11. The rotation of the deflecting system 11 is provided by the springs 25 in open slots, and its movement along the tube axis is provided by gaps in the projections 30. With the transverse adjustment of the deflecting System 11 deflection of springs 15-18 and 25 occurs.
    The adjustment in the vertical direction can be made without changing the position in the horizontal direction and vice versa. So, if it is necessary to move the deflecting system of the vertical without affecting its horizontal position, loosen the two horizontal bolts 23 or 28 and move the body 10 With the deflecting system 11 vertically. Similarly, horizontal movement can be obtained by loosening vertical bolts 23 or 28. The effect of the arcuate springs 15-18 is illustrated in FIG.
    The use of the present invention simplifies the process of adjusting the position of the deflection system relative to the electron beams of the cathode ray tube.
