Abstract
The utility model discloses a kind of high performance mini transformer device, comprise a skeleton, the first magnetic core, the second magnetic core, described skeleton central authorities are provided with one longitudinally through the magnetic core groove on the upper and lower surface of skeleton, and lower surface is medianly zygomorphic is provided with one group of magnetic core draw-in groove; Described skeleton is provided with a winding slot between upper and lower two surfaces; Being installed on skeleton upper and lower surface of described the first magnetic core, the second magnetic core symmetry.This transformer device structure is optimized design, has reduced the size of skeleton and magnetic core, makes the outward appearance dexterity of product attractive in appearance, reduces material usage, reduces costs.
Description
Technical field
The utility model relates to a kind of transformer device structure, relates in particular to high performance mini transformer device, belongs to transformer parts technical field.
Background technology
Existing EE13 miniature transformer thickness has reached 13mm, and product appearance is too fat to move, and material usage is large, and product cost is higher.
, when the core production of existing EE13 miniature transformer, be easily out of shape, fraction defective is high meanwhile, and assembly difficulty is large, and speed is slow, and finished product inductance value error is also larger.This is just in the urgent need to the easy moulding of a kind of magnetic core, and yields is high, not yielding, good assembling, and inductance consistency is high, the new micro transformer device structure that inductance value accuracy is high.
Summary of the invention
The utility model, in order to overcome the deficiencies in the prior art, provides high performance mini transformer device, its objective is the thickness that reduces product, makes the outward appearance dexterity of product attractive in appearance, reduces material usage, reduces costs.Meanwhile, make the easy moulding of magnetic core, yields is high, not yielding, good assembling, and inductance consistency is high, and inductance value accuracy is high.
In order to solve above-mentioned technical problem, basic solution technical scheme of the present utility model is:
High performance mini transformer device, comprises a skeleton, the first magnetic core, the second magnetic core, and described skeleton central authorities are provided with one longitudinally through the magnetic core groove on the upper and lower surface of skeleton, and lower surface is medianly zygomorphic is provided with one group of magnetic core draw-in groove; Described skeleton is provided with a winding slot between upper and lower two surfaces; Being installed on skeleton upper and lower surface of described the first magnetic core, the second magnetic core symmetry.
Further set forth, on described skeleton lower surface, be also provided with 2 groups or 3 groups of PIN stitch, for external primary coil lead-in wire and secondary coil lead-in wire.
Further set forth, after described the first magnetic core, the second magnetic core assemble, the thickness between the upper surface of the first magnetic core and the lower surface of the second magnetic core is 10.4mm.
The invention has the beneficial effects as follows:
1, the thickness that reduces product, makes the outward appearance dexterity of product attractive in appearance, reduces material usage, reduces costs;
2, make the easy moulding of magnetic core, yields is high, not yielding, good assembling, and inductance consistency is high, and inductance value accuracy is high.
Brief description of the drawings
Fig. 1 is the overall structure figure of the utility model high performance mini transformer device;
Fig. 2 is the blast structure chart of the utility model high performance mini transformer device;
Fig. 3 is the structure chart of the utility model high performance mini transformer device magnetic core;
In figure: high performance mini transformer device 1, the first magnetic core 11, skeleton 12, the second magnetic core 13, magnetic core groove 121, winding slot 122, magnetic core draw-in groove 123.
Embodiment
Below with reference to accompanying drawing 1, Fig. 2, Fig. 3, the utility model is described further, but should limit the scope of the invention with this.
For convenience of description and understand technical scheme of the present invention, the orientation that the noun of locality that below explanation is used is all shown with accompanying drawing is as the criterion.
As shown in Figure 1, high performance mini transformer device 1, comprises a skeleton 12, the first magnetic core 11, the second magnetic core 13.
As shown in Figure 3, this transformer device structure skeleton 12 central authorities are provided with one longitudinally through the magnetic core groove 121 on skeleton 12 upper and lower surfaces, and lower surface is medianly zygomorphic is provided with one group of magnetic core draw-in groove 123; Skeleton 12 is provided with a winding slot 122 between upper and lower two surfaces, and coil windings is wire-wrapped in winding slot 122.
As shown in Figure 2, being installed on skeleton 12 upper and lower surfaces of the first magnetic core 11, the second magnetic core 13 symmetries, central magnetic core is just in time placed in magnetic core groove 121, and magnetic core both sides are stuck in magnetic core draw-in groove 123.
Meanwhile, when enforcement, for going between and secondary coil lead-in wire by external primary coil, on transformer framework lower surface, be also provided with 2 groups or 3 groups of PIN stitch.
Simultaneously, after the first magnetic core 11, the second magnetic core 13 assemble on skeleton 12, thickness between the lower surface of the upper surface of the first magnetic core and the second magnetic core is only 10.4mm, is significantly smaller than the thickness of EE13 miniature transformer 13mm, has obviously reduced the size of this transformer device structure 1.
The announcement of book and instruction according to the above description, those skilled in the art in the invention can also change and revise above-mentioned execution mode.Therefore, the present invention is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present invention modifications and changes more of the present invention.In addition,, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the present invention.
