Description

The transformer coiling structure

Technical field

The utility model relates to a kind of transformer coiling structure, refers to a kind of transformer coiling structure that is used for converter (Inverter) especially.

Background technology

General transformer is that an iron core is set in the roll, coil with identical or different line footpath is wound in first siding ring and second siding ring on roll again, coat with a housing again after twining first siding ring and second siding ring on this iron core, so can constitute the transformer of an induction coil and be applied to provide the electronic installation of electric power, as liquid crystal panel etc., and general liquid crystal panel adopts a plurality of cold cathode fluorescent lamp to improve the brightness of liquid crystal panel in processing procedure mostly, so above-mentioned transformer must cooperate the design of a plurality of second siding rings with a plurality of first siding rings, could export many group drive currents to drive these cold cathode fluorescent lamp, but this design can cause drive current difference that the secondary side that drives cold cathode fluorescent lamp exports and brightness irregularities, and the electric current that the drives cold cathode fluorescent lamp problem of briliancy of throwing light on that concerning again.

As shown in Figure 1, user mode schematic diagram for known transformer, as shown in the figure, mainly include iron core group 100, two groups of first siding rings 110 that are set around iron core group 100 mid portions respectively, 120, two groups of second siding rings 130 that are set around iron core group 100 two ends respectively, 140 and two loads 30, and this first siding ring 110,120 with this second siding ring 130,140 are respectively isolated with a distance piece 101, wherein, input voltage (Vi) is imported this first siding ring 110,120, these iron core group 100 excitatory backs of process are by this second siding ring 130,140 provide drive current and drive rear end load 30 (load 30 is a cold cathode fluorescent lamp), though this transformer can be supplied electric power to two load, it is formed structure and also derives following point:

One, because two loads 30 are the same ends that are arranged at iron core group 100, so be set around two groups of second siding rings 130 at the two ends of iron core group 100 respectively, 140, certainly will have one group must be when circuit board (PCB) prints, this could be organized second siding ring 130 in the wire jumper mode, 140 are connected to rear end load 30, and driven, or must just this can be organized second siding ring 130 with double-layer circuit board, 140 are connected to rear end load 30, the practice like this, not only processing procedure is more complicated but also consume man-hour, if with the double-layer circuit board setting, not only increase its design difficulty and also increase cost of manufacture, be not inconsistent the demand of industry now in fact.

Two, the design of this known core group 100, formed with two E sections cores, its inter-engagement part two ends, in order to this first siding ring 110 of difference winding, 120, not only make the discontinuous facts of loss that also can cause of the magnetic line of force take place, moreover, aforesaid this second siding ring 130,140, be set around the two ends of iron core group 100 respectively, cause sensibility reciprocal difference and output voltage and drive current to produce bigger difference easily, and drive current is in order to drive two loads 30 of rear end, as this second siding ring 130,140 drive current is unequal, must cause these two loads, 30 illumination luminance nonuniformities of rear end.

Above variety of problems, real be now the producer problem extremely to be solved.

The utility model content

Main purpose of the present utility model, be to improve above-mentioned defective, and can export a plurality of identical drive currents driving the load of rear end in secondary side, and can simplify structure and can allow rear end load power output identical with primary side that single iron core and single winding body twined.

For achieving the above object, the utility model proposes a kind of transformer coiling structure, include a drum stand, this drum stand has primary side and secondary side and input voltage is carried out exporting after the voltage transitions, and this secondary side is provided with a plurality of dividing plates and separates out winding slot, wherein, at least two juxtaposed winding bodies are wound on these winding slots across these dividing plates in regular turn.

By technique scheme, make the utility model produce following beneficial effect compared to known technology:

One, is wound in the secondary side of this drum stand jointly by these two winding bodies, make this transformer reel not need to organize in addition to establish circuit board, or via of at least two loads of mode transferring electric powers such as wire jumper to this secondary side rear end, thereby simplify the structure of transformer, and reduce the effect of processing procedure required time and production cost.

Two, also be wound in this drum stand the same side, make this secondary side can produce identical driving electric supplying with this two loads, and then make the load power output identical by these two winding bodies.
