A deflection yoke for a cathode-ray tube, includes a pair of vertical deflection coils, a pair of horizontal deflection coils and a rigid separator insulating the pairs of deflection coils from each other. The separator has on its surface an arrangement for positioning and holding in place front and rear parts of saddle-shaped deflection coils. The arrangement forms an integral part of a body of the separator and is produced when molding the body.

Electron beam deflection system for a cathode ray tube

A cathode ray tube display with scanning beam velocity modulation comprises a cathode ray tube with a neck and gun for generating an electron beam. A deflection yoke is mounted on the cathode ray tube for electron beam deflection. A first flexible support having a side for conductor fabrication and a second flexible support having a side for conductor fabrication are superimposed and wrapped to conform to the neck circumference. A first coil pattern is formed as a conductor on the first conductor fabrication side and a second coil pattern is formed as a conductor on the second conductor fabrication side. A conductive connection couples between the first coil pattern and the second coil pattern. A connector couples scanning velocity modulation current to energize said first coil pattern and said second coil pattern for scanning beam velocity modulation.

Flexible auxiliary deflection coil

A yoke separator or liner includes a body having a conical shape and a ring shaped retraining member that is attachable to a rear portion of the body by four pairs of pawls and studs. A beam s velocity modulation coil is installed on a support member made of flexible material using a printed circuit technique. The studs are inserted in orifices formed in the support member. The pawls snap onto the studs and press against the support member in a manner to secure the modulation coil.
