Abstract

The invention provides a closed loop iron core coiling structure which comprises a closed loop iron core, a photosensitive layer, a conductive layer and a plurality of connecting endpoints, wherein the photosensitive layer is positioned on the surface of the closed loop iron core and is patterned to form two parallel spiral patterns surrounding the closed loop iron core; the conductive layer is attached to the parallel spiral patterns to form two spiral coils; and the plurality of connecting endpoints are connected to two ends of the spiral coils. According to the invention, by attaching the spiral conductive layer to the surface of the closed loop iron core to form the coils, the problem that the closed loop iron core is too small to accurately wind the coils is solved. In addition, the invention provides a closed loop iron core coiling method.

Description

technical field [0001] The invention relates to an iron core winding method and structure, in particular to a closed loop iron core winding method and structure. Background technique [0002] In view of the trend that electronic products pay more and more attention to thinness, lightness and shortness, in the case of limited internal space of electronic products, there is a need for miniaturization of internal electronic components. Therefore, how to manufacture a filter that is small in size and complies with electrical safety regulations and maintains required efficacy is also an urgent problem. [0003] see figure 1 As shown, it is a schematic diagram of a closed loop iron core winding structure in the known technology. The closed-loop iron core 1a is generally made of manganese-zinc ferrite magnets or nickel-zinc ferrite magnets by pressing. The coil 21a and the coil 22a are metal wires, usually made of copper, whose outer layer is painted and insulated, and wound aro...
