Abstract
A choke coil of the present invention employs a dust core as a material for each core, and includes an outer core having a quadrangular frame shape, a bobbin on which a coil is wound and which is mounted in the frame of the outer core, and an inner core which serves as a magnetic core of the bobbin and which has a core-rod-like shape having a central axis parallel to the winding axial direction of the coil. The inner core is interposed between two flat surfaces facing each other in the inner face of the outer core such that the central axis extends in a direction orthogonal to the two flat surfaces.
Claims11
A choke coil comprising:
- an outer core made of a dust core, the outer core having a quadrangular frame shape at least on an inner face side thereof;
- a bobbin on which a coil is wound and which is mounted in the frame of the outer core;
- and
- an inner core made of a dust core for serving as a magnetic core of the bobbin, the inner core forming a core-rod-like shape having a central axis parallel to a winding axial direction of the coil, the inner core being interposed between two flat surfaces facing each other in the inner face of the outer core such that the central axis extends in a direction orthogonal to the two flat surfaces.
