Abstract

The utility model discloses a ring vertical deflection coil for a color kinescope, which is composed of an upper single coil and a lower single coil which can wind on an ring ferrite magnet core; the upper single coil consists of a left upper winding and a right upper winding which are eudipleural, and the lower single coil consists of a left lower winding and a right lower winding. The utility model can divide traditional vertical single coil into two windings of the left winding and the right winding; two windings which are respectively positioned at the left sides of the single coils can be connected so as to form a left coil group according to magnetic flux parallel/serial connection mode at the time of circuit connection; meanwhile, two windings which are respectively positioned at the right side of the single coils can be connected, so as to form a right coil group according to magnetic flux parallel/serial mode; the magnetic fluxes of the left/right coil groups are wholly and sequentially connected so as to form the main magnetic field of the vertical coil. Utilizing an adjustable potentiometer to change the assembling and distorting states, so as to realize the adjustability of the assembly and distortion.

Description

A kind of annular vertical deflecting coil of color picture tube

Technical field

The utility model relates to a kind of color picture tube deflecting coil, particularly a kind of annular vertical deflecting coil.

Background technology

In traditional color picture tube deflecting coil structure, have only the saddle type vertical coil to have the circuit adjustability of YV and trapezoidal distortion, and annular vertical coil lower as cost, that produce in enormous quantities again can't be realized such function.In the loop coil coiling is produced, tend to produce deviation, it is asymmetric to cause vertical coil YV to assemble, be T, B order blue in or blue phenomenon such as outer, trapezoidal distortion or these convergences and the conflicting phenomenon of distortion up and down also can appear, the operator uses the correcting element adjustment, need take a long time and energy.

Summary of the invention

The utility model is in order to improve the operating efficiency of coil debugging operation and homogeneous tube ITC operation, a kind of novel annular vertical deflecting coil is provided, can realize the dynamic convergence that only on the saddle type vertical coil, could implement and the circuit adjustability of distortion, have characteristics simple in structure, that testing and measuring technology is easy, with low cost.

For achieving the above object, the utility model takes following technical scheme to be achieved:

A kind of annular vertical deflecting coil of color picture tube is characterized in that: comprise being wound on the last monomer coil on the annular ferrite core, the body coil that places an order, last monomer coil is made up of symmetrical upper left winding and upper right winding; The body coil that places an order is made up of symmetrical lower-left winding and bottom right winding.

When circuit connects, can be with upper left winding and the lower-left winding left coil group that forms in parallel; With upper right winding and the right coil groups of bottom right winding formation in parallel; The left coil group is connected with right coil groups again.Also upper left winding and lower-left windings in series can be formed the left coil group; Upper right winding and bottom right windings in series are formed right coil groups; The left coil group is connected with right coil groups again.

The utility model has the advantages that: with the monomer coil windings of traditional vertical coil, be divided into symmetrical two windings, in vertical coil, just form four windings like this.By the mode of magnetic flux parallel connection, connect two left windings on the left side and two right windings on the right, keep the magnetic direction of vertical coil constant.Thereby realized the correspondence of magnetic field, the left and right sides and left and right coil groups,, separated being included in a contradiction characteristic in the monomer coil originally.

Another advantage of the present utility model is: utilize two resistance and adjustable potentiometers that are connected in parallel on left and right coil groups two ends respectively, the electric current of realizing these two coil groups is variable, make the both sides bundles (R electron beam and B electron beam) that are in respectively about magnetic field, be subjected to the action of a magnetic field of different sizes, change and assemble and distortion status, realize the controllability of convergence and distortion.Under the condition that material is constant and technique change is less, improve the yields of coil, improve the operating speed of debugging operation.
