Description

A kind of two coiled pipe type inductor that twines

Technical field

The utility model relates to a kind of inductor, especially relates to a kind of two coiled pipe type inductor that twines.

Background technology

In known technical field, the design of traditional inductor adopts normal ferrite magnetic core, this inductor is for reaching small inductor amount, must open very large air gap to FERRITE CORE, in order to reach high-power, logical large electric current, needs again large volume simultaneously, this volume larger in practice is difficult to accept, and can not obtain the inductance value that precision is higher.Therefore, how providing a kind of small inductor amount, high-power, large electric current, small size and high-precision inductor is technical issues that need to address.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of pair to twine coiled pipe type inductor, make inductor have small inductor amount, high-power, large electric current, small size and high-precision feature.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of two coiled pipe type inductors that twine, on having, lower upper cylinder end cap and the lower cylinder end cap arranging respectively, in region on described between cylinder end cap and lower cylinder end cap, be arranged at intervals with left magnetic column and right magnetic column, on described left magnetic column and right magnetic column, be wound with respectively left copper cash group and right copper cash group, cylindrical end covers and is provided with anodal access point and negative pole access point on described, and two exits of described left copper cash group are weldingly fixed on respectively anodal access point and negative pole access point, two exits of described right copper cash group are weldingly fixed on respectively anodal access point and negative pole access point, the cross section of described left magnetic column and right magnetic column is all half-circle-arc shape, between described left magnetic column and right magnetic column, be provided with electro-insulating rubber piece.

Further, as a kind of concrete fixed form, the two ends of left magnetic column described in the utility model are adhesively fixed with the lower surface of upper cylinder end cap and the upper surface of lower cylinder end cap respectively, and the two ends of described right magnetic column are adhesively fixed with the lower surface of upper cylinder end cap and the upper surface of lower cylinder end cap respectively.

Further, as a kind of concrete fixed form, the utility model is all coated with epoxy resin layer in the outermost of described left copper cash group and right copper cash group.

Adopted technique scheme, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, the version of organizing by two windings, simplify the volume of inductor, make inductor there is small inductor amount, high-power, large electric current, small size and high-precision feature.

Wherein: 1. go up cylinder end cap, 11. anodal access points, 12. negative pole access points, 2. descend cylinder end cap, 3. left magnetic column, 31. left copper cash groups, 4. right magnetic column, 41. right copper cash group, 5. electro-insulating rubber pieces.

embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As Fig. 1, two coiled pipe type inductors that twine shown in Fig. 2 and Fig. 3, on having, lower upper cylinder end cap 1 and the lower cylinder end cap 2 arranging respectively, in region on described between cylinder end cap 1 and lower cylinder end cap 2, be arranged at intervals with left magnetic column 3 and right magnetic column 4, on described left magnetic column 3 and right magnetic column 4, be wound with respectively left copper cash group 31 and right copper cash group 41, on cylinder end cap 1, be provided with anodal access point 11 and negative pole access point 12 on described, and two exits of described left copper cash group 31 are weldingly fixed on respectively anodal access point 11 and negative pole access point 12, two exits of described right copper cash group 41 are weldingly fixed on respectively anodal access point 11 and negative pole access point 12, the cross section of described left magnetic column 3 and right magnetic column 4 is all half-circle-arc shape, between described left magnetic column 3 and right magnetic column 4, be provided with electro-insulating rubber piece 5.

The two ends of described left magnetic column 3 are adhesively fixed with the lower surface of upper cylinder end cap 1 and the upper surface of lower cylinder end cap 2 respectively, and the two ends of described right magnetic column 4 are adhesively fixed with the lower surface of upper cylinder end cap 1 and the upper surface of lower cylinder end cap 2 respectively.

Outermost in described left copper cash group 31 and right copper cash group 41 is all coated with epoxy resin layer.

The utility model is simple in structure, reasonable in design, and the version of organizing by two windings is simplified the volume of inductor, makes inductor have small inductor amount, high-power, large electric current, small size and high-precision feature.
