Embodiment Construction

[0023] Specific embodiments are listed below to describe the content of the present invention in detail, and illustrations are used as auxiliary descriptions. The symbols mentioned in the description refer to the symbol symbols.

[0024] Please refer to figure 2 As shown, it is a schematic diagram of the closed loop iron core winding structure proposed by the present invention. The closed loop iron core winding structure proposed by the present invention includes a closed loop iron core 31 , a conductive layer 32 and a plurality of connection terminals 33 . The closed loop core 31 can be made of MnZn ferrite or NiZn ferrite. After covering part of the surface of the closed loop iron core 31 through a shield (not shown in the figure), the conductive layer 32 is attached to the uncovered part of the closed loop iron core 31 to form two parallel helical coils around the closed loop iron core 31 . A plurality of connection terminals 33 are respectively connected to two ends o...

Abstract

The invention provides a closed loop iron core winding structure, comprising a closed loop iron core, a conducting layer and a plurality of connection endpoints. After at least shielding and covering a part of surface of the closed loop iron core, the conducting layer is attached to the uncovered part of the closed loop iron core so as to form two parallel spiral coils surrounding the closed loop iron core. The plurality of connection endpoints are connected to the two ends of the spiral coils. A coil is formed on the surface of the closed loop iron core through the conducting layer attached with the spiral conducting layer. The problem that the coil cannot be wound accurately when the closed loop iron core is small can be solved. Furthermore, a closed loop iron core winding method is further provided herein.

Description

technical field [0001] The invention relates to an iron core winding method and structure, in particular to a closed loop iron core winding structure and a manufacturing method thereof. 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 formed by pressing manganese-zinc ferrite magnets or nickel-zinc ferrite magnets. The coil 21a and the coil 22a are metal wires, usually made of copper, whose outer layer is painted and i...
