    A deflection yoke comprises a core and at least two layers of conductor turns wound about the core. A return traverse conductor traverses the core from a finishing conductor turn of one of the layers to a starting conductor turn of the other layer. At least three projections are located adjacent an outer surface of the core for providing pivot points for the return traverse conductor. A first projection is located near a starting conductor turn of one of the layers, a second projection is located near a finishing conductor turn, and a third projection is located between the first and second projections for preventing the return traverse conductor from protruding beyond a core end.

    The invention relates to television technology, in particular to devices, to the deflection of an electron beam.
    Deflecting systems (OC) based on the principles of electron beam deflection in a magnetic field and made, for example, in the form of saddle-shaped coils, spanning the neck of the kinescope Ij are known.
    However, such operating systems do not provide sufficient repeatability of mixing parameters in production.
    Closest to the proposed OS is an annular magnetic core extending in the axial direction and a set of turns of a toroidal multilayer winding comprising a reverse transverse wire intersecting the magnetic conductor from the final turn of one of the layers to the initial turn of the subsequent layer 2j
    In this OS, when winding wires according to various known methods, when moving from one layer to another, reverse transverse wires are formed, which are laid at a large angle to the longitudinal axis of the magnetic circuit. These wires create parasitic magnetic fields that distort the resulting image.
    In particular, the method of winding on a reverse helix, although it allows to obtain a relatively fast transition, however, is associated with the necessity of laying transverse turns of the wire on the inner active surface of the magnetic circuit. Laying the inner wires of the second and subsequent layers of turns with sufficient accuracy is complicated by the fact that the wire must be laid over the transverse turns of the return wire. The use of the reverse helix method also leads to a relative decrease in the sensitivity of the internal wires of several first layers. Since the subsequent layers must be laid on top of the transverse wires, each n next layer may be more and more. deform or go out into the inner space of the core, which eliminates the need to increase
    the diameter of the magnetic circuit while reducing the efficiency of the OS.
    In order to eliminate the internal transverse wires, crossing in the opposite direction can be carried out by another known method of the reverse method.
    In this case, the runner belt is periodically stopped at given points, creating zones free of internal wires. When one of these zones reaches its reverse crossing, the slider stops, lays the inner wire in the longitudinal direction, then continues to rotate, moving along the outer surface of the magnetic core element until it reaches another gap, and then lays the other longitudinal wire. These operations are repeated until the slider occupies the initial position of the next layer. As a result, only the outer transverse wires remain, and the inner ones are actually part of the active inner wires of the previous layers. However, the slider stops increase the time required for laying the layer of turns, and consequently, for the manufacture of a core element with a full winding consisting of multiple layers.
    The aim of the invention is to reduce the influence of the parasitic magnetic field by eliminating the transverse wires on the inner surface of the magnetic circuit and reducing the time
    winding.
    This goal is achieved by the fact that in a deflecting system comprising an annular magnetic core, expanding in the axial direction, and a multilayer winding of a toroidal type, including a reverse transverse coupling from the final turn of one of the layers to the initial turn of the subsequent layer, on its outer surface ends made at least three protrusions, two of which are located in the zone of the initial and final turns, and the third is located between the first two, and the reverse transverse
