Abstract (en)
[origin: EP0169613A1] A saddle coil for a deflection coil assembly in an electromagnetic deflection unit is formed from a plurality of layer each of which comprises a conductive pattern on an insulating film and may be produced by printed wiring techniques. Each layer is constructed from first and second lamelliform parts, the first of which is substantially 'U' shaped, these parts being assembled by distorting the shape of the first part and bridging its distal ends, which may have inward facing projections (14A, 15A), with the second part. In the assembled layer the transverse limb of the first part is at the gun end (9) and the flared side limbs of this part form the side members (11,12) whilst the second part forms at least part of the screen end (13). Conductive patterns on the first and second part are interconnected to form a coil. A number of such layers so formed are assembled to produce the saddle coil with the required electrical connections between the layers. Saddle coils produced in this manner have the advantage that the conductors are accurately positioned from coil to coil with a consequence accuracy of deflection. Two such saddle coils are used to form a deflection coil assembly (line and/or field) which assemblies can be used in the construction of a deflection unit.
