Description

Triple channel high-tension transformer structure

Technical field

The utility model relates to a kind of transformer device structure of burning voltage to electronic installation that be used to export, and is specifically related to the bias light transformer that a kind of volume I provides three groups of stability characteristic (quality)s 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, present large-screen (more than 19 cun) LCD adopts four above fluorescent tubes more, and is evenly distributed according to different modes on screen.Though for preferable display effect can appear in the more fluorescent tube of number, but being based on each alterating and direct current pressure converter of original technology drives, and an alterating and direct current pressure converter also needs a transformer to cooperate, therefore the number of fluorescent tube is many more, the number of electric pressure converter and transformer also increases thereupon, it is big that the volume of relative display also must become, and except that the cost increase of product, the requirement of slimming also can't be reached.And every tubes needs identical brightness and can guarantee that the brightness of display screen is even, and the brightness of a tubes is mainly guaranteed by current's intensity, thereby needs to use multichannel technology to guarantee the current balance type of every tubes.For this reason, binary channels and 4 passage transformer device structure technology have been developed at present, but present technology spininess is to 2 fluorescent tubes, 4 fluorescent tubes, 8 fluorescent tubes, modules backlight such as 16 fluorescent tubes seem that then efficient is not high and are difficult to lay printed circuit board (PCB) with respect to 20 ~ 22 cun 6 fluorescent tubes commonly used and 12 later fluorescent tubes, and this is real to be the difficult problem of industry.

The utility model content

In order to solve an above-mentioned difficult problem, the purpose of this utility model provides a kind of triple channel high-tension transformer structure, it combines the dual characteristics of UU, EE structure, output parameter providing away by different three directions will be equated, can provide the output of three groups of complete equipilibriums simultaneously, in order to drive 3 or 6 or 12 CCFL fluorescent tubes.

To achieve these goals, the utility model adopts following technical scheme:

Triple channel high-tension transformer structure, comprise magnetic core, glue core, insulated copper wire, secondary winding and elementary winding, it is characterized in that: at grade, distance is identical and be fixed on around the elementary winding between at least 3 secondary winding and elementary winding, primary and secondary winding is independent disjunct separately individual, pass secondary winding and be connected one, make the magnetic circuit between each winding equal fully with the magnetic core of elementary winding.

An above-mentioned secondary winding is vertical with the distance of elementary winding with two secondary winding of distance and other of elementary winding.

Distance between above-mentioned secondary winding equates.

The utility model structure can be provided with a plurality of passages, and the magnetic circuit operation principle of each passage is equivalent to the loop of a plurality of E types.In order to realize gathering around simultaneously the magnetic core in a plurality of E types loop, realize this purpose so respectively add a side column two of magnetic cores.Its advantage is to guarantee that above-mentioned a plurality of passage all has the electrical characteristic of a balance.The utility model is realized increasing the transformer number by a plurality of outputs, and the thin characteristics of volume.
