The upper conductive foil such as Copper Foil of laying of printed circuit board (Printed circuit board, PCB) as winding,
The transformator of storehouse, the winding of this planar structure can be substantially reduced the thickness of transformator.Plane transformation
Device is widely used in the products such as communication, computer, Industry Control, aeronautical engineering, armarium.But,
Due to printed circuit board machining process and the limitation of copper clad layers thickness, the umber of turn that monolayer Copper Foil is formed
The most extremely limited with water conservancy diversion cross section, it is suitable only for the utilization condition of some small-power low voltage DC/DC changers.Right
In requiring umber of turn more (such as: there is the AC/DC of high voltage input) or requiring larger current density
Application occasion, can only be by the string of the circuit board of multilamellar the requirement reaching the number of turn and electric current density, this
Sample one carrys out flat surface transformer and is accomplished by using the circuit board of quite a lot of number of plies to build up, make flat-plate transformer little,
Thin structure feature is all gone.Meanwhile, make between Winding Design, board layer, to cross line and all define technology difficulty
Degree and manufacturing cost rise violently；Blocked up winding causes stray transformer flux to raise on the contrary, efficiency reduces, noise is done
The a series of problem such as disturb.As can be seen here, existing its practicality of plate surface transformator is quite to limit to.
How at the bar keeping many technical characteristics such as printing board type flat surface transformer slimming, low magnetism leakage, high efficiency
Under part, effectively solve the technical barrier that above-mentioned industry urgently overcomes.The technology puts into the technology of research and development just
Background.
Summary of the invention
This utility model is for the deficiencies in the prior art, it is proposed that a kind of plane being applicable to twin columns core structure

A kind of flat-faced tube winding coil being applicable to twin columns core structure, especially one can pass through lamination
The two-sided PCB of combo flat surface transformer covers copper coil.
The plated through-hole pad that the initial and end end of pcb board series connection winding is all arranged from the outer edge of pcb board
Draw；Have two magnetic core posts arranged in parallel on pcb board and through hole is installed；With double-sided copper-clad base material cabling,
And form four windings around two core pole holes；Each core pole hole edge passes through copper face cabling via, makes to enclose
The copper cabling that covers being around in same stem stem is formed around to identical " double-deck series connection winding "；Make around different cores
Two " double-deck series connection windings " of post i.e. may make up twin columns, four windings in series by around to carrying out on the contrary connecting
Imposite winding.
Described each core pole hole edge passes through multiple copper face cabling vias.
Beneficial effect:
1, this utility model is changed conventional print-circuit board and is made the technology limitation of flat surface transformer single-column winding,
Under conditions of identical winding current carrying density, the number of turns of lamina face twice and the winding of four times can be obtained
Inductance value；
2, compared with the board-like winding of single-column structure, can minimizing at double under conditions of identical umber of turn
Total number of plies of board-like winding, greatly reduces the gross thickness of board-like transformator, is to realize plate surface transformator
The key technology of slim words；
3, between the twin columns that this technological innovation is released, 8 font strings, around connection, cross the winding of line in post center interlayer
Method of attachment, makes the design of form printed circuit coils winding become very simple, makes identical number of plies printed circuit lines
Circle realizes number of turns and maximizes；
4, this technology is by serial for the standardized structural that printed circuit Winding Design is " two-sided winding soleplate ".
Corresponding magnetic core and soleplate is matched, by string winding according to the transformer parameter required by various electric source topologies
Flaggy obtains required umber of turn and winding current, combo can become the various dissimilar and transformation of specification
Device.Change the limitation that traditional circuit-board winding can only be special；Meanwhile, printed circuit winding system is greatly reduced
The technical difficulty made and higher processing cost.The flexible craft making normalized base plate combo transformator becomes
Reality
5, this printed circuit winding soleplate winding relates to into the symmetrical structure that the twin columns number of turn is divided equally, it is ensured that
Magnetomotive balance between twin columns, makes the specification of magnetoelectricity electromagnetism and the minimizing of leakage magnetic flux obtain fabulous effect；
6 diaphragms that are dielectrically separated from simultaneously used from this soleplate combo transformator can be by different dielectric strengths
Join and insulate between lap winding, isolate physical layer and make the isolated form AC/DC, DC/DC of the various topology of high density combo all
Become and facilitate technique and technology；
7, use the technology can directly save compared with tradition and coiling making high frequency transformer and account for tradition work
Skill coiling expends the processing cost of about 50%, and cannot ensure and make quality and the technique of transformator
The limitation of mode, is also the important prerequisite of conventional highfrequency transformator automated production.
