Abstract
The utility model relates to a section frame deflector which is a frame deflector used by a high definition television. The section frame deflector is composed of magnetic cores, a spring clamp and coils, wherein, the magnetic cores are a section type and a separated type. The magnetic cores which are separated are connected together through the spring clamp. The coils are distributed on each section of the magnetic cores. The utility model has the advantages of high deflection sensitivity, low magnetic loss, small aberration, light weight, etc. The structure of the section type magnetic core enhances the definition. A magnetic field which is desired can be easily designed. The utility model is suitable for being used in high definition display devices.
Description
The utility model relates to the frame deflection device that high definition TV is used in the vacuum display device field.
All adopt horn-like magnet ring or long column type magnetic core with the outer frame deflection device of pipe in the existing pipe, and coiling is cosine formula continuous distribution structure.Because this structure can't further reduce aberration, also further the requirement of managing the intrinsic deflection device is satisfied in weight reduction, promotes clearness so influenced further.
The utility model has provided a kind of interior frame deflection device of pipe that can be applicable to High Resolution Display spare at the problems referred to above.
The utility model is horn-like, is made up of magnetic core (1), Spring Card (2), coil (3).Wherein magnetic core (1) is split, segmented, and by Spring Card (2) magnetic core of split being connected becomes an integral body, and coil (3) is distributed on each section of magnetic core.
The utility model compared with prior art has the deflection sensitivity height, and the magnetic loss is low, advantages such as aberration is little and in light weight because magnetic core adopts split, segmentation structure, have improved definition, and easily design required magnetic field, be suitable for using in the High Resolution Display spare.
Fig. 1 is the utility model structural representation.
Fig. 2 is the expanded view of Fig. 1.
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
For the horn magnetic core, be designed to symmetrical segmentation, split type, magnetic core outer surface two magnetic core joints are arranged with two lugs, are blocked by Spring Card (2), and it is joined together; Magnetic core (1) is big, toy trumpet segmentation symmetry concave-convex surface, for 14～19 cun: the protruding degree of depth of toy trumpet stomatodeum is 2～4mm, the protruding degree of depth of typhon stomatodeum is 1～3mm, in order to reduce deflection power, magnetic core toy trumpet mouth internal diameter can be 19～20mm, external diameter is 30～31mm, magnetic core typhon mouth internal diameter can be 36～39mm, external diameter can be 40～42mm, the long 7～8mm of the straight line portion of magnetic core, and the shape of magnetic core can be consistent with the shape that the computer optimization designing and calculating goes out, and core material adopts R2K～R5K high frequency high resistant height to lead ferrite, both improved deflection sensitivity, and reduced magnetic loss and thermal losses again, the segmentation angle of magnetic core (1) is α
1=31～32 °, α
2=α
3=13～14 °, α
4=63～64 °.
During coiling, in order to guarantee vacuum performance, the enamelled wire of coil can adopt polyimide enameled wire on above-mentioned magnetic core, for the ease of joining closely with the row packing, the flyback part must be in the magnetic core outside when frame held line, and section has the apparent in view line of demarcation that shows with section in magnetic core (1) inboard like this, was convenient to the row bag and embedded, make capable frame structure compactness, reduce whole deflection volume, be convenient to microminiaturization, reduced the frame deflection installation weight simultaneously, be easy to manage internalization, and reduced aberration.
Because the vacuum performance requirement, Spring Card (2) can adopt high spring steel alloy.
Make according to the method described above, both can realize the utility model.
