Abstract
The utility model relates to a dual-magnetic-line four-channel dual-winding transformer, comprising a magnetic corn, two rubber corns, an insulated cover, and an insulated copper wire. The invention is characterized in that two rubber corns, while the magnetic corn through the cover is inserted into the holes of the rubber corns, each rubber corn is fixed with a winding area of one primary winding and the winding areas of two secondary windings, the primary windings are fixed between two secondary windings, each winding area is disposed with the plug position of at least one winding. The invention can be used in membrane electric crystal or liquid crystal display, and direct-current converter of cold cathode tubular lamp, while the signal is input from the primary winding to form four channels in four secondary windings to generate four output to drive four luminous tubes, wherein the middle post of the magnetic corn is exposed to improve the heat radiation of magnetic corn most.
Description
Technical field
The utility model relates to a kind of transformer device structure, is used to export burning voltage to electronic installation, is specifically related to a kind of bias light transformer that the double magnetic circuit of four groups of burning voltages can be provided simultaneously.
Background technology
In the prior art, have suitable many about the structural improvement of transformer, main purpose all is how to reduce the volume of transformer, this shows the demand property of volume-diminished, especially current electronic installation is many with little, microminiaturized, the slim trend that turns to of volume, accordingly, relevant electronic building brick configuration promptly must be followed the reduced volume design, and reduce and build the space of putting; With the sizable display unit of demand in the market, promptly towards the main developing direction that is designed to of slimming, yet the design of slimming has but comprised many urgency technical bottleneck to be overcome.The main separated into two parts of LCD light source: external light source and back light, external light source belong to objective uncontrollable light source, are absorbed outward by the liquid crystal crystal; And back light is provided by cathode fluorescent tube, is the main light source at the inner liquid crystal panel back side, and its brightness, the uniformity directly influence color contrast, full screen regional luminance effect, visible angle or the like.Because the problem of self character and technology in the display left and right sides and central authorities, the phenomenon of brightness irregularities usually can obviously occur, is referred to as " dark space ".Phenomenon for the dark space, the number that increases fluorescent tube is a kind of more general mode, so large-sized LCD screen must use many fluorescent tubes just can reach certain display effect, four above fluorescent tubes of the many employings of present big screen LCD are arranged in parallel on screen.Though for preferable display effect can appear in the more fluorescent tube of number, but in fact, one tubes promptly needs an alterating and direct current pressure converter to drive, and an alterating and direct current pressure converter also needs a transformer to cooperate, therefore the number of fluorescent tube is many more, and the number of electric pressure converter and transformer also increases thereupon, and it is big that the volume of relative display also must become, except that the cost increase of product, the requirement of slimming also can't be reached.
The utility model content
The purpose of this utility model provides a kind of double magnetic circuit four-way bias light transformer, and it is luminous that it can drive four or eight luminous tubes simultaneously.And keep current balance type between each root fluorescent tube.
To achieve these goals, the utility model adopts following technical scheme:
Double magnetic circuit four-way double wrap coil holder transformer device structure, it comprises magnetic core, glue core, insulation lid, insulated copper wire, it is characterized in that: two glue cores are fixed in the insulation lid, the both sides magnetic core of E type magnetic core passes the insulation lid respectively and inserts in the hole of corresponding glue core, on each glue core, fix the winding region of a primary coil and the winding region of two secondary coils respectively, primary coil is fixed on the centre of two secondary coils, and the groove position of at least one coiling is set on each winding region.
The utility model structure can produce a higher secondary leakage inductance, and the magnetic circuit operation principle is different with mill run, and the magnetic core center pillar does not have winding, and two secondary winding and an elementary winding are installed in respectively on two side columns of magnetic core, forms the magnetic circuit of two UU types.Two magnetic circuits will pass through the magnetic core center pillar simultaneously.Thereby obtain four higher secondary leakage inductances.The parameter of same four secondary winding is all identical with structure, and work magnetic circuit is very symmetrical, is easy to obtain the secondary leakage inductance of four balances.Export the leakage inductance of four balances and the requirement that high voltage just can satisfy conventional power LCD simultaneously.Replace existing single channel and twin-channel transformer easily, because existing those transformers all are the designs of low leakage inductance and high voltage output.
Lid described in the utility model can accurately be located two glue cores, control effectively winding to the safe distance of winding, each winding is to the safe distance of magnetic core; Lid can be isolated secondary high pressure to people or the discharge of other article, also can prevent dust; Perforate on the lid can improve the effect of the heat dispersion and the impregnation varnish of winding.Maximum characteristics allow the magnetic core center pillar be exposed, and have improved the magnetic core heat dispersion widely.
Bias light transformer described in the utility model can be used for membrane transistor or LCD, and on the cold cathode lamp direct current transducer.Signal is imported from primary coil, forms four passages at four secondary coils, produces four outputs and removes to drive four luminous tubes.Like this, a four-way transformer is equivalent to four or eight existing transformers, and less its occupation space; Stable performance and useful life that the appearance of four secondary leakage inductances of balance, good radiating mode and alignment buffer has improved product.
