Abstract
The invention provides a novel deflecting coil with low cost which is composed of a saddle-shaped horizontal coil, an annular vertical coil wound on an annular ferrite magnetic core, and a coil skeleton, a terminal plate and an opening portion lateral magnetic block, shape of the inner curved surface of the magnetic core is designed in similar to a tube awl, the horizontal coil is provided with an internally-recessed structure with opening turn-over and is also provided with a neck half turn-over trapezoid structure, which improves strength and distribution of a body magnetic field, forms high magnetic beam density in an effective region within a teletube, enhances deflecting sensitivity of electronic beams and eradicates various distortions (pincushion distortion, seagull distortion, internal distortion and the like) caused by reduction of the coil structure, and various high order aberrations ([delta]HCR, [delta]VCR and the like). In addition to meeting the primary features of the deflecting coil, the inventive deflecting coil has the characteristics, compared to the conventional deflecting coil for teletube, of high efficiency, small volume, light weight, 10% of cost reduction in comparison to the conventional deflecting coil.
Description
Technical field
The invention belongs to color picture tube/display tube deflecting coil and make field, specifically a kind of deflecting coil that is applicable to tricolour picture tube.
Background technology
Current 25 " FS (tricolour picture tube) deflecting coil is eight, the product of the nineties design, the design margin broad, and the power of consumption material big, that use is many, and weight is also heavier.In order to improve this coil; Reduce materials used and cut down the consumption of energy, design and a kind of low-cost deflecting coil of producing are under the constant condition of deflection power; Efficient design through the horizontal and vertical lines circle; Dwindled the coil shape structure, realized each item characteristic of deflecting coil equally, the material of use also reduces widely.
The utility model content
The objective of the invention is to realize a kind of deflecting coil cheaply, under same deflection power, materials used can reduce more than 10%.
For realizing above-mentioned function; Technical scheme of the present invention is: a kind of deflecting coil; The skeleton of the pipe awl of picture tube is provided with a pair of horizontal coil, is arranged on vertical coil, the magnetic patch of magnetic core periphery, and horizontal coil has half turnup structure and trapezoidal-structure at neck; Have the structure of caving in and local no turnup structure at peristome.Designed with the positive camber shape of pipe awl is approaching by the negative camber shape of the magnetic core of vertical coil winding, and be close on the horizontal coil positive camber of pipe awl.Saidly be arranged on half turnup structure of horizontal coil, the part of trapezoidal-structure winds the line direct loop line around the ancillary coil top, another part around half flange above be trapezoidal-structure.
The flange centre that is arranged on the horizontal coil peristome has the part wire turn recessed to coil inside, is local no turnup structure.The neck that is arranged on horizontal coil presents two segmentation distributed architectures, and is provided with the space; Peristome presents three segmental structures, is provided with the space.
On the core shapes of frame deflector coil carrier, adopt and pipe awl curve and the closely approaching design of horizontal coil positive camber curved surface on the one hand, shortened the magnetic loop path, improved magnetic field intensity.Be on the other hand on the horizontal deflection coil structure, adopt neck half flange trapezoidal-structure, make horizontal coil big around circle density, magnetic field distribution is concentrated, and the efficient in magnetic field is improved; The peristome flange of the horizontal coil structure of caving in makes the magnetic field of coil aperture portion be strong pincushion and distributes, and has improved top bottoms pincushion and sea-gull distortion.Proofread and correct magnetic patch in four bights that the coil peristome is provided with simultaneously, the segment design of hydrous water flat coil, the contradiction of having separated pattern distortion and convergence has been eliminated high order aberrations such as Δ HCR, Δ VCR, makes each item characteristic of coil satisfy instructions for use.
Characteristics of the present invention are: after taking above loop construction design, compare with traditional deflecting coil, reduced the use of material, dwindled deflecting coil length or volume, realized that cost is low, volume is little, lightweight deflecting coil.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Referring to Fig. 1, the structural representation of deflecting coil of the present invention, deflecting coil is made up of a pair of horizontal coil 1, pair of vertical coil 2 and magnetic core 3, coil rack 5, peristome magnetic patch 4 etc.
Referring to Fig. 2, be the schematic cross-section of low-cost deflecting coil of the present invention, near the magnetic core curved surface 13 of pipe awl curved surface 6 designs, compare forr a short time with the magnetic core overall dimension of traditional deflecting coil, optimize and form magnetic core cross section 14.Become small coil structure more closely, shortened magnetic loop, improved the sensitivity of coil.
Referring to Fig. 3, the contour structures sketch map of horizontal coil 1 of the present invention, the coiling of neck 7 distributes, and the space 18 of being pinned is divided into two sections coilings; The flange of neck 7 distributes, and the direct loop line of part coiling is around ancillary coil 15 tops 16, another part around half flange 8 on form ladder type 9 and distribute; The coiling of peristome distributes, and the space 19 and 20 of being pinned is divided into three sections coilings; Some wire turn of peristome zone line forms the local no turnup structure 12 of peristome to coil inside depression 11.
The coiling distributed architecture of this coil; Make Distribution of Magnetic Field that multipole variation take place; Improved the convergence performance of the electron beam deflecting to the phosphor screen corners; Improve characteristics such as convergence characteristics, distortion such as pincushion distortion, the sea-gull distortion of whole deflecting coil, interior distortion, reduced various high order aberrations such as Δ HCR, Δ VCR etc.
