Abstract
The utility model relates to a kind of miniaturization high-power transformer components；Including magnetic core, with a root multi-layer insulated wire successively secondary side of coiling and the flatwise coil being independently made at the primary side of N number of ring pie of series-like and N+1 using enamel-cover flat type copper wire；N number of ring pie and N+1 flatwise coil are superimposed, and are assemblied on magnetic core center pillar；The distance between the utility model has deliberately pulled open distance between the copper sheet on flatwise coil pair side, while also having pulled open primary side ring pie, play the role of fine security isolation, while being conducive to radiate, realizes small size assembly.
Description
Technical field
The utility model relates to transformer technologies, and in particular to a kind of miniaturization high-power transformer component.
Background technique
In the high-power high-currents products such as exploitation Switching Power Supply, it is desirable that higher and higher power density, that is, it is necessary
Power is constantly improved under identical volume.But the promotion of power will be so that small product size increase, increased costs；With
It is desirable to smaller volume, lower cost is contradictory.Therefore existing transformer device structure, is difficult to meet this requirement.
On November 09th, 2011, Chinese utility model patent Authorization Notice No. CN202034188U are disclosed a kind of flat
Coil-copper sheet type transformer, the primary side including turning to line pie with three layer insulation wire, the secondary side being made into using copper sheet and magnetic
Core, primary and secondary side are assemblied on magnetic core center pillar, and secondary side uses copper sheet, are placed with insulating film between the copper sheet on secondary side, can be carried
High current, can effectively reduce copper loss, and it is thermally conductive also to can be used as radiator.But this transformer is due to distance between the copper sheet on secondary side
It is close, when needing to carry bigger electric current, generates heat and be easy heap aggregation, it is of no avail increasing copper sheet quantity.
To solve the above-mentioned problems, we are made that a series of improvement.
Utility model content
The purpose of the utility model is to provide a kind of miniaturization high-power transformer components, to overcome prior art institute
Existing disadvantages mentioned above and deficiency.
The technical solution of utility model is as follows:
A kind of miniaturization high-power transformer component, comprising: magnetic core, with a root multi-layer insulated wire successively coiling and at series connection
The secondary side of the primary side of N number of ring pie of shape and the N+1 flatwise coil being independently made into using enamel-cover flat type copper wire；N number of ring cake
Shape coil and N+1 flatwise coil are superimposed, and are assemblied on magnetic core center pillar；All first extractions of the N+1 flatwise coil
End in parallel is a total first exit, and all tail exit parallel connections are a total tail exit；
Above-mentioned N number of ring pie the number of turns is all the same, around to consistent when assembly；Above-mentioned N+1 flatwise coil, each the number of turns
Also identical, around to consistent when assembly;
The N is the integer greater than 2.
Further, the ring pie and flatwise coil overlap two-by-two between be placed with insulating film.
The utility model has the beneficial effects that
The primary and secondary side of the utility model all it is exposed in air, winding itself generate heat distributed by air.
The utility model is compared with traditional technology, with multiple flatwise coil pair sides for separating independent coiling, flatwise coil pair
Primary side ring pie is accompanied between side, has deliberately pulled open distance between the copper sheet on flatwise coil pair side, while also having pulled open original
The distance between side ring pie plays the role of fine security isolation, while being conducive to radiate, and realizes small size dress
Match.The utility model flatwise coil consistency is good, does not influence whole production difficulty, and synchronous production may be implemented, and improves work
Efficiency reduces production cost.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the connection signal view of 3 ring pies of the utility model.
Appended drawing reference: 1 magnetic core；2 ring pies；3 flatwise coils；4 first exits；5 tail exits.
Specific embodiment
Below in conjunction with specific embodiment, progress explanation is made to the utility model.It should be understood that following embodiment is merely to illustrate
The utility model is not for restriction the scope of the utility model.
Embodiment 1
Fig. 1 is the structure chart of the utility model.
As shown in Figure 1, a kind of miniaturization high-power transformer component, comprising: magnetic core 1, with a root multi-layer insulated wire successively
Coiling and the flatwise coils 3 being independently made at the primary side of three ring pies 2 of series-like and four use enamel-cover flat type copper wires
Secondary side；Three ring pies 2 and four flatwise coils 3 are superimposed, and are assemblied on 1 center pillar of magnetic core；Described four flat
All first exits 4 of coil 3 in parallel are a total first exit, and all tail exits 5 in parallel are a total tail exit；
Above three ring 2 the number of turns of pie are all the same, around to consistent when assembly；Aforementioned four flatwise coil 3, each circle
Number is also identical, around to consistent when assembly.
Insulating film is placed between the overlapping of the ring pie 2 and flatwise coil 3 two-by-two.
