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.
A method of mounting a deflection unit on a cathode ray tube envelope, comprising disposing a deflection unit on the envelope, the deflection unit having at least six connecting members, pairs of the connecting members having corresponding ends connected at spaced apart positions to the deflection unit, each connection point being contiguous with a connection point of an end of an adjacent member of another pair, the members of each pair being mutually convergent so that their terminal portions are contiguous;
A display device comprising a cathode ray tube having an envelope formed of an optically transparent faceplate, a neck and a conical portion interconnecting the faceplate and the neck, a deflection unit disposed about the neck-conical portion transition of the envelope, and at least six elongate connecting members connecting the deflection unit to at least three points of attachment on the conical portion, pairs of the connecting members having corresponding ends connected at spaced apart positions on the deflection unit, each connection point being contiguous with a connection point of an end of an adjacent member of another pair, the members of each pair being mutually convergent so that their terminal portions are attached substantially contiguously to the conical portion, the pairs being inclined with respect to a longitudinal axis of the cathode ray tube, the inclination of each of the pairs being such that each pair is substantially tangential to the conical portion at its point of attachment therewith so that substantially shear stress is applied to the point of attachment.
