Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Conventional transformer is upper around the former secondary winding of multiturn at an iron core (ferrite iron core), thereby produces larger leakage inductance, causes larger noise and loss.
Its winding mode of the transformer of current use is mainly: a roll, one is wound in the coil on this roll, one assembly is placed in the iron core on roll, one is packaged in aforementioned roll forms with outside housing unshakable in one's determination, and two can divide into a primary coil and secondary coil at the aforementioned coil being wound on roll.And aforesaid primary coil and secondary coil are in the time being wound around, first primary coil is wound on elementary bobbin groove position, after primary coil has been wound around, on same bobbin, be wound around again secondary coil, therefore, secondary voltage is higher, and the number of turns is more.
For above-mentioned defect, having some correlation techniques solves, mainly to adopt copper cash to be wound around in lamination mode, the number of secondary turns that winding completes, the equal stay aligned of every circle copper cash, between copper cash, potential difference is less, and every layer of copper cash all coated one deck insulation film isolate doing, be difficult for forming short circuit, can guarantee transformer output electrical characteristic, and can improve confidence level and the quality of transformer.
In order further to improve high efficiency and the high-quality of transformation, also traditional iron core can be divided into two winding regions and wind the line and increase operation rate and output quality.But the mode of its coiling is one deck primary coil in the past and one deck or the stack of multilayer secondary coil still.
But coil winding mode in the past is not well positioned to meet the demand in market, output precision is little, and withstand voltage is little etc.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art, a kind of method for winding of transformer coiling group is provided, its objective is the winding mode that changes current enamelled wire, save winding space, improve winding efficiency, delivery efficiency and output accuracy, reduce the impact of coiling on output.

Embodiment
Below with reference to accompanying drawing 1 to Fig. 4, the present invention is described further, but should not limit the scope of the invention with this.
Contrast Fig. 1 to Fig. 4:
The basic technical scheme of the method for winding of transformer coiling group of the present invention is:
(1) become the magnetic core of closed to be divided at least one winding region one Intermediate Gray through hole and head and the tail;
(2) parallel with secondary rolling thread elementary coiling placement arranged side by side is formed at least one group of coiling; And
(3) at least one group of above-mentioned coiling being around in respectively at least one described winding region forms at least one group of coiling group and consists of transformer group.
As known technology, transformer coiling group comprises iron core and is wrapped in the coiling group on iron core.But as innovative point of the present invention, it is wrapped on iron core side by side by elementary coiling is parallel with secondary rolling thread.In the present invention, iron core is circular; Certainly in addition, the iron core of use can be also frame structure.In the present invention, iron core is evenly divided into three winding regions, then three groups of coilings is wrapped in to three winding regions.
