COIL STRUCTURE AND ELECTROMAGNETIC COMPONENT USING THE SAME

摘要

An electromagnetic component including a multi-layer, spiral coil structure embedded in a molded body is disclosed. Each layer of the coil structure makes approximately one and a quarter turns of a winding. Each layer of the coil structure has a loose middle segment, two slim end segments overlapping each other with a spacing therebetween, and tapered neck segments respectively connecting the loose middle segment with the two slim end segments.

主权项

1. An electromagnetic component, comprising:
a conductive structure, comprising at least one conductive layer to form a coil, wherein a conductive layer comprises a middle segment, a first slim segment and a second slim segment, wherein the width of the middle segment is respectively greater than that of the first slim segment and the second slim segment, wherein a portion of an outer side surface of the first slim segment and a portion of an inner side surface of the second slim segment are placed side by side for matching the line width of the middle segment with a total of the width of the first slim segment, the width of the second slim segment and a spacing between said two slim segments.
