Definitions

  • the holding the vertical deflection coils and the ring in position ferromagnetic material is accomplished through a crown 13, coming to be fixed on rails 10 arranged on the substantially cylindrical part of the separator 2; this separator is also provided with feet, the housings 11 are shown in the figure, as well as a crown elastic 14 allowing the fixing of the deflection device 1 on the neck of the tube thanks to a clamping collar arranged around 14.
  • the crown 13 slides in the rails 10 until the deflection coils are pressed vertical against the front of the separator; a step of bonding the crown 13 completes the immobilization of the assembly.
  • This device does not can however be used reliably only for the assembly of toroidal type vertical deflection coils, i.e.
