Abstract
The utility model discloses field controller of color kinescope, comprising the symmetrical edges of the rectangle plane. Two symmetrical edges are respectively provided with stiles which are vertical to the edges, while the other two symmetrical edges are provided with lug bosses; the geometric centre of the field controller element is provided with a circular pore which has the same pore diameter as the electron beam of the central cap. The utility model has a unique structure and convenient manufacture; therefore, the problem of coma is solved.
Description
One, technical field
The utility model relates to a kind of field controller of color picture tube, particularly a kind of field controller that is complementary with super flat panel color picture tube of 40cm and the pure flat panel color picture tube of 40cm.
Two, background technology
The field controller is the interior part of a pipe of color picture tube, be installed in the convergence cap of electron gun, its role is to control the rear portion leakage magnetic flux of deflecting coil, the deflection sensitivity of the middle relatively bundle of limit bundle is changed, thus the coma aberration on the correcting color picture tube picture.Usually auto-convergence yi word pattern color picture tube all produces coma aberration, and most economical solution is for being provided with a controller in picture tube.Yet according to kind, size and manufacturing firm's difference of color picture tube, the planform and the size of a controller are also far from each other.
Three, technology contents
The purpose of this utility model is to overcome the shortcoming that above-mentioned prior art can not satisfy new type colorful picture tube needs, provides a kind of physical dimension uniqueness, technology to realize easy field controller, and the problem of coma aberration is resolved.
To achieve the above object of the invention, the technical solution of the utility model is: on two symmetrical limits of controller rectangular plane on the scene perpendicular stile is set, be provided with boss on two other symmetrical limit, the geometric center position of controller part on the scene is provided with the circular hole that equates with the electron beam aperture of convergence cap.
The utility model also has following characteristics: a material that controller adopted is the iron-nickel alloy band with high magnetic property.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model rectangle plane.
Five, embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
With reference to Fig. 1, Fig. 2, the utility model comprises the symmetrical limit of rectangle plane 1, two symmetrical limits at rectangle plane are respectively arranged with perpendicular stile (3), be provided with boss (2) on two other symmetrical limit, the geometric center position of controller part on the scene is provided with the circular hole that equates with the electron beam aperture of convergence cap (4).
Operation principle of the present utility model is as follows: a controller is welded on two lateral opening places of convergence cap (4), is respectively arranged with perpendicular stile (3) on two symmetrical limits of rectangle plane, and vertical stile (3) is vertical with X-axis towards Y direction.Be provided with boss (2) on two other symmetrical limit, boss (2) is vertical with Y-axis towards X-direction.
The utility model technology realizes easy, has realized good coupling with super flat panel color picture tube of 40cm and the pure flat panel color picture tube of 40cm, thereby has solved the problem of coma aberration.
Claims (2)
- A color picture tube the field controller, the symmetrical limit that comprises rectangle plane (1), it is characterized in that: on two symmetrical limits, be provided with perpendicular stile (3) respectively, be provided with boss (2) on two other symmetrical limit, the geometric center position of controller part on the scene is provided with the circular hole that equates with the electron beam aperture of convergence cap (4).
- 2. the field controller of a kind of color picture tube according to claim 1, it is characterized in that: the material that controller adopted is the iron-nickel alloy band with high magnetic property.
