Abstract
The utility model discloses a kind of transformer framework, the magnetic core center pillar comprising supporting base and be mounted thereon, described magnetic core center pillar is provided with some baffle plates, cross-line space is installed with between the described baffle plate of same level, described magnetic core center pillar is divided into upper groove, middle slot and lower groove by the described baffle plate being positioned at same vertical plane, wherein said upper groove, lower groove are used for coiling, and middle slot is vacated, and is also provided with top board above described magnetic core center pillar.This transformer framework, by design baffle plate, magnetic core center pillar is divided into upper groove, middle slot and lower groove, the single groove in existing structure is made to become multiple-grooved, when winding divides groove coiling, adjustment leakage inductance that can be effective and stable, effectively restriction winding position does not offset, and middle slot is beneficial to the product self heat that sheds, eliminate that barricade, wide high temperature gummed tape etc. are used design, reduce product cost and improving product overall appearance degree.
Description
Technical field
The utility model relates to field transformer, is specially the transformer framework that a kind of cost is low and both artistic and practical.
Background technology
Transformer framework, also known as transformer coil holder, being the agent structure composition in transformer, is the parts that in transformer one is indispensable.
The main effect of transformer framework is that the magnetic core of stationary transformer, for the stitch of transformer provides support, the installation for transformer provides necessary interface for the coil in transformer provides the space of winding.Along with socioeconomic development, transformer is widely used, and the quality of transformer is very important, and correspondingly, whether the performance of transformer framework is qualified, and the requirement whether reaching use is equally also very important.
And the design of existing transformer framework is reasonable not, structure still there is defect, is mainly manifested in:
1, when high-power transformer or inductance open dark air gap, the magnetic core center pillar temperature rise of transformer framework is higher, and the barricade temperature resistant grade intercepting winding is low, and barricade trap heat sheds and meeting carbonization;
2, barricade can squeeze crooked by product actual winding process line bag, causes the temperature rise of magnetic core center pillar higher and to affect Total Product attractive in appearance;
3, special transformer can have special requirement to leakage inductance, how to regulate degree of coupling between winding to be crucial;
4, barricade increases products material cost, and coiling expends man-hour.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of Novel transformer bobbin being applicable to the number of turns is few, air gap is dark transformer or inductance, and its good heat dissipation effect, cost are low, and reasonable in design, Total Product aesthetics is high.
The utility model solves the technical scheme that its technical problem adopts:
A kind of transformer framework, the magnetic core center pillar comprising supporting base and be mounted thereon, described magnetic core center pillar is provided with some baffle plates, cross-line space is installed with between the described baffle plate of same level, described magnetic core center pillar is divided into upper groove, middle slot and lower groove by the described baffle plate being positioned at same vertical plane, wherein said upper groove, lower groove are used for coiling, and middle slot is vacated, and is also provided with top board above described magnetic core center pillar.
As the improvement of technique scheme, described top board front and back end all offers the lead-out groove of the fly line extraction being beneficial to not hanging feet.
As the improvement of technique scheme, described magnetic core center pillar is provided with four pieces of baffle plates, wherein between the described baffle plate of same level, front and back is all installed with cross-line space, and the equal decile of described magnetic core center pillar is divided into upper groove, middle slot and lower groove by the described baffle plate being positioned at same vertical plane.
The beneficial effect that the utility model brings has:
This transformer framework, by design baffle plate, magnetic core center pillar is divided into upper groove, middle slot and lower groove, the single groove in existing structure is made to become multiple-grooved, when winding divides groove coiling, adjustment leakage inductance that can be effective and stable, effectively restriction winding position does not offset, and middle slot is beneficial to the product self heat that sheds, eliminate that barricade, wide high temperature gummed tape etc. are used design, reduce product cost and improving product overall appearance degree.
