Abstract
The utility model discloses a fly back transformer for black and white picture TV, which is improved in structure of three aspects comparing with the existing fly back transformer; (1) a high and low pressure coil bobbin in the shape of a straight barrel is designed; (2) a ferrite core has a design of unequal section; (3) high voltage diodes adopt a structure installation of 'plug-in type '. The utility model has the advantages of simple structure, high reliability and low cost, which can be applied for various black and white picture televisions.
Description
The utility model relates to the integrated kickback transformer that a kind of television set assembly, particularly black and white television receiver are used.
Through the retrieval of Shanghai research institute of scientific-technical information, there be not to find the black and white television receiver integrated kickback transformer identical with the utility model.Before the utility model is made, the integrated kickback transformer of black and white television receiver, its skeleton majority is the slot type structure, prismatic magnetic core is fastening by U bolt, high-voltage diode adopts support to fix, the product structure complexity, especially the skeleton of multi-groove structure, groove is narrow and dark, and the mould manufacturing is difficulty quite, during the coiling embedded coil, to having relatively high expectations of enamelled wire, even use the special varnish envelope curve, reliability of products is still relatively poor, most factory products failure rates are about the W level, and product cost is higher.
The purpose of this utility model provides a kind of simple in structure, good reliability, the black and white television receiver kickback transformer that cost is low.
Main points of the present utility model are: the skeleton to kickback transformer has been done redesign, has promptly designed the skeleton of straight barrel shaped structure, and coil adopts the layer of interlayer pad insulation film to carry out coiling around mode; FERRITE CORE adopts the non-constant section design; The high-voltage diode mounting means has been done improvement---adopt " plug-in type " structure.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The utility model by housing (10), high-tension coil (7), low-voltage coil (8), high-voltage diode (5), magnetic core (6), magnetic core folder (4), and leading foot (9), cavity cap (1), high-voltage line (2), sheath parts such as (3) form.Housing (10) is injection molded with the flame retardant type engineering plastics, is divided into upper and lower two-section, goes up to cut to be provided with straight barrel-shaped coil rack, the tube chamber that inserts high-voltage diode (5) and the outlet of high-voltage line (2) etc.Following section is provided with low-voltage coil skeleton and 8 leading foots.The internal diameter of low-voltage coil skeleton is slightly larger than footpath outside the high voltage ring skeleton.High-tension coil (7) by the preceding working procedure coiling after, refill the skeleton that go up to cut to housing (10), low-voltage coil (8) can directly be wound on the low pressure skeleton of following section of housing (10).Magnetic core (6) is made up of two block-shaped, physical dimension and all identical " U " shape ferrite magnetic material of magnetic permeability, in order to reduce the distributed capacitance of coil, the inventor has made particular design to the cross section of " U " shape magnetic material: under the prerequisite of the magnetic circuit total characteristic in not changing former design, the design of employing non-constant section is about to magnetic core (6) and is designed to insert the sectional area of the interior magnet sectional area of high and low pressure coil rack less than the housing outer magnet.In the utility model, the magnetic core that inserts coil rack is a cylinder, is positioned at the outer magnet cross section of housing (10) and is square, and the cylinder cross-sectional diameter equals the length of side of the outer four-prism cross section of housing.Two blocks of " U " shape magnetic materials by one with heavy wire make " (" shape magnetic core folder (4) is fixing.High-voltage diode (5) is connected with high-tension coil (7) and high-voltage line (2) after inserting the tube chamber of housing (1) again.The electrical connection of related elements in the utility model and the television set, in full accord with existing integrated kickback transformer.
--once assembling--dehumidifying--embedding--secondary assembling--detection--packing that main process flow process of the present utility model is: the high-tension coil coiling.
Compared with prior art, the utility model is simple in structure, and materials are few, and cost can reduce more than 15%, and product reliability is good, and the material of coiling can with common QA enamel-covered wire, need not to use Special enameled wire.
