Abstract
The invention relates to a coil, in particular to a deflection coil comprising a line deflection coil, a field deflection coil, a magnetic ring and a central adjusting ring, wherein the field deflection coil is directly wound outside the magnetic ring, the line deflection coil is divided into an upper winding and a lower winding, the upper winding and the lower winding both penetrate through a magnetic ring hole and are in saddle shapes, and the central adjusting ring is located at the rear end of the magnetic ring. The deflection coil is simple in structure, reasonable in winding of the line deflection coil and the field deflection coil, and capable of well controlling scanning motion directions of electron beams.
Description
Technical field
The present invention relates to a kind of coil, especially a kind of deflecting coil.
Background technology
Deflecting coil is the important composition parts of CRT picture tube, is enclosed within the cone position of picture tube and is connected with scanning circuit on the substrate, in order to realize the row-field scanning function of image.The winding of line deflector coil and field deflection coil directly affects the scanning motion direction of electron beam in the deflecting coil.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides the rational deflecting coil of a kind of winding.
The technical solution adopted for the present invention to solve the technical problems is: a kind of deflecting coil is provided, comprise line deflector coil, field deflection coil, magnet ring and center adjustment ring, field deflection coil is directly outside magnet ring, line deflector coil is divided into up and down two windings, all pass the magnet ring hole, two winding profiles are the shape of a saddle, and the center adjustment ring is positioned at the magnet ring rear end.
The material of described magnet ring is ferrite, can play the effect of filtering, noise reduction.
The invention has the beneficial effects as follows: the present invention is simple in structure, and the winding of line deflector coil and field deflection coil is reasonable, controls well the scanning motion direction of electron beam.
