Abstract
Deflection unit for a display tube, comprising a coil support (8) with a saddle-type field deflection coil (12) and a yoke ring (14) surrounding this coil. A form-filling adhesive material (extending between the open portions of the field deflection coil as far as the support) is provided in the free space between the support (8) and the yoke ring (14), with which material the support and the field deflection coil are rigidly connected to the inner surface of the yoke ring. Vibrations of the yoke ring, and noise generated by the coil support due to transmission of these vibrations to the support, are substantially prevented, particularly if the adhesive material also has a damping effect, or if a thin layer of visco-elastic material preferably realizing a detachable connection between the adhesive material and the yoke ring is provided between this adhesive material and the yoke ring.
