Abstract
The utility model discloses a double-ring 8-shaped anti-magnetic coil, which is characterized in that the back surface of a kinescope is provided with two groups of frame-shaped anti-magnetic coils. The two groups of anti-magnetic coils are connected with any side of a deflecting coil, and the outgoing line of the deflecting coil is connected with a plug. The utility model has the advantages of novel structure, uniform degaussing, low cost, pure true color of pictures and strong anti-interference capability. The double-ring 8-shaped anti-magnetic coil also can obviously reduce the copper loss cost of the coils.
Description
Technical field:
The utility model relates to a kind of coil, relates more specifically to a kind of color picture tube, display tube of being used for, for eliminating earth magnetism, the used two circle 8 font anti-magnetized coils of stray magnetic field.
Background technology:
Be used for colour TV now, the anti-magnetized coil of colour display screen, of a great variety, its version is not outer in five kinds, as: the individual pen outer ring, semi-circular, the following figure of eight, the horizontal figure of eight, reach anti-magnetized coils such as two casts, the defective of the equal various degrees of these products, the demagnetization ability that has is inhomogeneous, and is poor to the nearly core erasure effect of picture tube, or local demagnetization's weak effect, the lead that has is long, and it is many to consume enamelled wire, the cost height, the crosspoint that has is many, the magnetic line of force is cancelled out each other, cause the anti-magnetized coil induction line, the interference of field causes the variation of picture tube colour purity, and general two cast anti-magnetized coils, the manufacturing process complexity, cost is higher, and DeGrain is difficult for promoting.
Summary of the invention:
The utility model provides a kind of two circle 8 font anti-magnetized coils, not only adopts two cast anti-magnetized coils in the design, and adopts horizontal, vertical 8 font syndetons, reaches the series and parallel connected mode, has overcome the weak point of above-mentioned anti-magnetized coil.
The technical solution of the utility model is: a kind of two circle 8 font anti-magnetized coils, it is characterized in that: be provided with the anti-magnetized coil of two groups of shaped as frames at the back side of picture tube, two groups of anti-magnetized coils are connected in any side of deflecting coil, and its lead-out wire connects a plug.
The utility model novel structure, demagnetization is even, with low cost, the figure euchroic is pure, and antijamming capability is strong, also can obviously reduce the copper loss cost of coil, is a kind of optimization product that is worthy to be popularized.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another example structure schematic diagram of the present utility model.
Fig. 3 is a parallel connection type circuit diagram of the present utility model.
Fig. 4 is a tandem type circuit diagram of the present utility model.
Among the figure: 1 picture tube, 2 anti-magnetized coils, 3 deflecting coils, 4 lead-out wires, 5 plugs
Embodiment:
As shown in Figure 1: the utility model is provided with two groups of shaped as frames at the back side of picture tube 12, two groups of anti-magnetized coils 2 of anti-magnetized coil are connected in any side of deflecting coil 3, and its lead-out wire 4 connects a plug 5.
As shown in Figure 1 and Figure 2: two groups of anti-magnetized coils 2 of the present utility model can be fixed in a upper and lower side of deflecting coil 3, for perpendicular 8 words connect, also can be fixed in a left and right side of deflecting coil 3, for horizontal 8 words connect.
As shown in Figure 3, Figure 4: two groups of anti-magnetized coils 2 of the present utility model can back attachment plug 5 in parallel, the back attachment plug 5 of also can connecting.
As Fig. 1, Fig. 2 arrow, shown in Fig. 3, Fig. 4 stain: the current direction of two groups of anti-magnetized coils 2 of the present utility model up and down symmetry, phase place to instead.
In sum, structure of this product and mode have four kinds of types of attachment: two circles erect the perpendicular 8 word tandem types of 8 word parallel connection types, two circle, the horizontal 8 word parallel connection types of two circle, the horizontal 8 word tandem types of two circle, thereby are applicable to the picture tube fields such as colour, display, monitor of any specification and model.
This product is when 34 cun colour kinescope alternating current 220V work:
The original product anti-magnetized coil requires: AT=4600ATp-p, field-discharge resistance=9 Ω encloses * 2 around 100 for 0.70 millimeter with diameter of wire and connects, internal resistance=18 Ω, 1.95 meters long of copper cash, consumption copper 1501 grams.
With this product anti-magnetized coil: for reaching AT=4600ATp-p, with field-discharge resistance=9 Ω * 2, one coil adopts 0.51 millimeter of diameter of wire around 118 circles, internal resistance=20 Ω, 2.04 meters of copper cash are long, and another coil adopts 0.44 millimeter of diameter of wire around 101 circles, internal resistance=20 Ω, 1.74 meters of copper cash are long, and two groups of anti-magnetized coils only consume copper 759 grams, than anti-magnetized coil joint copper 742 grams of original product.
The above-mentioned superiority that has more fully shown this product aspect demagnetization ability, image symmetrical, energy savings, is that other products does not have especially.
