ABSTRACT:
A cathode ray tube display device which has an arrangement for mounting a deflection unit on the conical portion of a cathode ray tube envelope. In order to permit a rapid mounting of the deflection unit in a manner which provides shock resistance, and resistance temperature fluctuations in the deflection unit and the envelope, three V-shaped, sheet metal connecting devices connect the deflection unit to the conical portion of the envelope. The free ends of the devices are attached to the deflection unit in such a manner that the vertices of the devices are substantially tangential to the surface of the conical portion. After adjustment of the deflection unit the vertices of the devices are secured to the conical portion in such a manner that the connections are loaded with a shearing force.
