The utility model discloses the inductor winds coil winding immediately by the individual layer flat line and on the arc magnetic core, is single line contact or point contact between the coil adjacent turns, and the parasitic capacitance that the coil formed is the series connection of all numbers of turns, and inductor EMC effect is improved by a wide margin. Coil individual layer coiling structure is that the flat line winds immediately moreover, and the space is great between line and the line, is favorable to the heat dissipation, reduces the temperature rise, and to the same application of power, the coil wire can adopt higher current density design, can promote the umber of turn.
Description
Technical field
The utility model relates to inductor, relate to specifically a kind of with Novel arc magnetic core, flat wire stand around inductor.
Background technology
Usual magnetic annular inductor, as boost inductor in PFC inducer, photovoltaic in communication and inversion inductor device adopt closed ring powder core magnetic core, because toroidal inductor technique for coiling cannot adopt machine coiling substantially, by hand wound, labour intensity is large and quality is unstable, discreteness is large, more, the shortcoming such as production efficiency is low consuming time, is widely used in toroidal inductor product.But along with the pay rise of workman, the advantage of toroidal core inductor is more and more not obvious, and the disappearance of Chinese labour force bonus, coiling inductor, annual cost of labor is increased beyond 20%, in this context, Novel arc magnetic core and flat wire is adopted to stand the automation that can realize processing around inductor, thus the use of few workman of slowing down.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of arc magnetic core and flat wire stand around inductor.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of with Novel arc magnetic core, flat wire stand around inductor, comprise magnetic core and the flat wire be around in outside magnetic core founds coiling, described magnetic core is arc, it comprises two or more arc magnetic core, together, form a closed toroidal core, described flat wire stands the periphery that coiling is wound in annular arc magnetic core to each arc core combination.
Further, described flat wire founds coiling is flat enamel covered wire or enamel-cover flat type aluminium wire pitch of the laps.
Further, it is that simple squamous line founds coiling that described flat wire founds coiling, and arc magnetic core is close to by its wire, and it is single linear contact lay or point cantact that described flat wire stands between the adjacent wire turn of coiling.
Further, the shape of the cross section of described arc magnetic core is rectangle.
Further, the material of described magnetic core at least comprises iron aluminum silicon powder, iron silica flour, iron nickel powder, iron nickel molybdenum, iron silicon boron.
Relative to prior art, the beneficial effects of the utility model are:
1. the utility model inductor founds coiling by simple squamous line and is wound on arc magnetic core, and be single linear contact lay or point cantact between coil adjacent turns, the parasitic capacitance that coil is formed is the series connection of all numbers of turn, and inductor EMC effect is greatly improved.
2. due to coil adopt pancake wire vertical around, wire can be close to magnetic core, owing to being individual layer coiling, and be close to magnetic core, therefore single turn wire rod used is the shortest, reduces the consumption of Coil resistance and copper cash, therefore, the utility model structure can improve product efficiency, can reduce inductor cost simultaneously.
3. owing to being individual layer winding structure, and be flat wire vertical around, space is comparatively large between the lines, is conducive to heat radiation, reduces temperature rise, and for the application that power is identical, winding wire can adopt higher current density design, can promote umber of turn.
4. flat wire is vertical around adopting machine coiling, is conducive to automated production, enhances productivity.
