Definitions

  • the present invention essentially relates to a method and a device ensuring the fixing on the neck of a cathode ray tube of the deflection collar of the tube, after adjusting the position of said collar relative to the tube.
  • the adjustment is carried out on machines, either manually controlled or automatic, which make it possible to determine the position of the deflection collar on the neck of the tube to obtain the best image performance of the tube (purity of colors and distortions in particular ).
  • the object of the invention is to provide an improved method and device making it very simple, reliable and inexpensive to obtain the correct positioning of the deflection collar on a tube of conventional construction, after adjusting the position. axial, centering or angle with the axis of the collar on the tube was determined in the manner and with conventional conventional machines.
  • the method of fixing on the neck of a cathode ray tube the deflection collar of the tube is characterized according to the invention in that the deflection collar is immobilized on the neck of the tube between a fixed stop adjustable in position, on which s 'supports the collar after adjusting its positioning, and an elastic annular ring which is disposed between the flared part of the tube and the collar.
  • This elastic ring being initially moved away from the collar by extension during adjustment so as to allow the collar to tilt relative to the fixed stop, then released to immobilize the collar after execution of the adjustment.
  • the operation is efficient, fast and economical.
  • the device according to the invention ensuring the fixing on the neck of a cathode ray tube of the tube deflection collar is characterized in that it comprises a fixed stop adjustable in position on the neck of the tube and serving to support a side of the collar and a fixed elastic stop clamped between the flared part of the tube and the other side of said collar.
  • an elastic stop is placed against the rear face 2 of the tube which is constituted in the example illustrated by an annular ring made of rubber or the like 6 kept stretched by any means (not shown) of the laying machine.
  • the ring can be maintained in a substantially flattened position, and in an extended state. In this position, the ring 6 therefore does not interfere with the positioning and subsequent positioning of the deflection collar 3 which is threaded onto the neck of the tube as indicated by the arrows 8.
  • the deflection collar 3 has been optimally positioned, that is to say so as to give the best rendering ment of use of the tube 1.
  • This position is determined in a conventional manner.
  • an adjustable fixed stop 9 which can be constituted by any mechanical means such as for example a metal clamping collar, which will grip the neck 5 of the tube.
  • the stop 9 can also be constituted by a washer, for example plastic, which will be glued to the neck 5 bearing behind the collar 3.
  • the material constituting the ring 6 it is advantageous to use a silicone elastomer or any other material having similar qualities of stability at high temperatures, elasticity and mechanical resistance.
  • the material constituting the ring 5 it is advantageous to use a silicone elastomer or any other material having similar qualities of stability at high temperatures, elasticity and mechanical resistance.
