Abstract
A coil device includes a first core, a second core, and a conductor. The first core includes a first leg. The second core is disposed with a gap between the first leg and the second core. The conductor is at least partly disposed between the first core and the second core. A notch is formed on the conductor at a position corresponding to the gap.
Claims19
A coil device comprising:
- a first core including a first leg;
- a second core disposed with a gap between the first leg and the second core and separated from the first core;
- and
- a conductor at least partly disposed between the first core and the second core,
- wherein a notch is formed on the conductor at a position corresponding to the gap,
- the conductor is an elongated body having an outer surface and an inner surface opposite to the outer surface,
- the notch notches the outer surface without penetrating the elongated body from the outer surface to the inner surface,
- the conductor includes a conductor side part extending along the first leg, and a mounting part being bent substantially perpendicularly to the conductor side part and extending outward along a bottom of the first leg,
- the notch is formed continuously from the conductor side part to the mounting part,
- the mounting part is arranged in a notch-shaped side groove formed at an end of the first leg of the first core,
- a ratio of a width of the notch in a direction perpendicular to an extending direction of the notch to a width of the conductor in a direction perpendicular to an extending direction of the conductor is 0.3 to 0.5,
- the notch-shaped side groove defines opening connecting an interior of the coil device with an exterior of the coil device,
- the mounting part is arranged in the opening,
- an end surface of the mounting part is exposed through the opening to the exterior of the coil device, and
- the ratio remains 0.3 to 0.5 in the opening.
