Patent Images
1. A coil device comprising:
- an inner core having a winding core with column shape extending in an axial direction and a pair of flanges arranged on both ends of the winding core;
a wire having (1) a winding portion winding around the winding core and (2) a first end and a second end extending from the winding portion;
an outer core having a through hole that receives the inner core and being arranged on an outer periphery of the inner core;
a first terminal portion provided with a first wirebound portion having a first wirebound bottom portion that (1) abuts a core end surface of one of end surfaces of the outer core in the axial direction and (2) is directly connected to the first end anda second terminal portion provided with a second wirebound portion having a second wirebound bottom portion that (1) abuts the core end surface, (2) is rotated in a peripheral direction by a predetermined angle from the first wirebound bottom portion on the core end surface and (3) is directly connected to the second end,wherein;
the first wirebound portion is provided with a first wire fixing portion bending from the first wirebound bottom portion toward a first rotating direction as seen from a tip side of the first end and fixing the first end, the first rotating direction being around a first axis of rotation that is perpendicular to the axial direction; and
the second wirebound portion is provided with a second wire fixing portion bending from the second wirebound bottom portion toward the same rotating direction as the first rotating direction as seen from a tip side of the second end and fixing the second end.

Abstract
A coil device includes an inner core having a winding core and a pair of flanges, a wire, an outer core arranged outside the inner core, a first terminal with a first wirebound having a first wirebound bottom arranged axially on a core end surface of the outer core and connected to a first end of the wire, and a second terminal with a second wirebound having a second wirebound bottom arranged on the core end surface and connected to a second end of the wire. The first wirebound has a first wire fixing portion bending from the first wirebound bottom toward a first rotating direction and fixing the first end. The second wirebound has a second wire fixing portion bending from the second wirebound bottom toward the same rotating direction as the first rotating direction and fixing the second end.
