Claims

[Scope of utility model registration request]

In a deflection yoke device comprising a coil bobbin, a horizontal deflection coil and a vertical deflection coil attached to the coil bobbin, the coil bobbin is attached to an in-line array color picture tube to deflect three electron beams. At the rear end, a pair of static convergence correction devices each having a correction coil wound around a U-shaped core are disposed facing each other upwardly and downwardly on both sides in a direction perpendicular to the in-line arrangement, and each static convergence correction device The correction coil is connected to a DC power supply, and each correction coil is configured to generate a correction magnetic field that concentrates the left and right electron beams arranged in-line into a central electron beam. Yoke device.
