Claims (6)

1. The deflection device for a cathode ray tube consists of a pair of horizontal deflection coils and a pair of vertical deflection coils, at least of which two pairs are in the shape of a workhorse. A separator separating the two pairs of coils, which acts as the main part of the front cone of the tube section on the deflection line, is arranged, and the front end, consisting of a rigid section that flares out from the tube frame and the inner circumference consisting of the main part, coils of the coil pairs in the shape of a workhorse, have an front lead, a rear lead, and a side group of lines connecting the front lead to the rear lead. The front lead is supported on one of the walls of the front end, which is characterized in such a way that at least the inner circumference of the front lead, which is in a radial angular position with a range between 0 and 30 degrees, is arranged above the inner circumference of the flared front end of the separator. 2. The device according to the preceding claim shall be characterized in such a way that at least one of the two walls of the anterior flared end is a truncated cone. 3. The device under claim 1 shall be characterized in such a way that the surface of the front end on which the workpiece coil is supported is perpendicular to the main Z-axis of the tube. 4. The device according to any of the preceding claims shall be characterized in such a way that the majority of the side wires are located in the front portion of the coils at an angular position with a range between 0 and 30 degrees. 5. Any device under any of the preceding claims shall be characterized in such a way that the workpiece coil shall be a horizontal deflection coil. 6. The cathode ray tube is constructed with an electron beam deflection device in accordance with any of the preceding claims.
