Abstract
A deflection coil consisting of a number of elementary coils formed by folding flat coils along four folding lines such that at the area of the folding lines each turn crosses all other turns. Very accurate deflection coils can thus be manufactured in a simple manner.
Claims3
A deflection coil for a cathode-ray tube having a partly flared outer surface, said coil comprising at least one elementary coil having a plurality of turns formed by at least one conductor, said conductor extending about a window, the elementary coil being folded along four folding lines, each folding line intersecting the turns only once, and each turn crossing all other turns only in the vicinity of each folding line.
