Abstract
An inductor includes a housing composed of an insulating material and a conical coil provided inside the housing. The conical coil is formed of a spirally wound coil conductor. The winding diameter of the conical coil increases in a continuous manner. The coil conductor has a rectangular cross section. Parts of the coil conductor that are adjacent to each other in a winding axis direction of the conical coil are disposed so as to partially overlap when looking in the winding axis direction of the conical coil. The insulating material of the housing is disposed without any gaps along the periphery of the coil conductor.
Claims19
An inductor comprising:
- a housing composed of an insulating material;
- and
- a conical coil provided inside the housing,
- wherein the conical coil is configured of a spirally wound coil conductor,
- a winding diameter of the conical coil increases in a continuous manner,
- the coil conductor has a rectangular cross section, an upper surface, a lower surface, and a peripheral surface extending from the upper surface to the lower surface,
- parts of the coil conductor that are adjacent to each other in a winding axis direction of the conical coil are disposed such that the upper surface of a first turn faces the lower surface of an adjacent second turn, so as to overlap where the upper surface of the first turn faces the lower surface of the adjacent second turn when looking in the winding axis direction of the conical coil,
- the insulating material of the housing is disposed without any gaps along a periphery of the coil conductor, and
- the rectangular cross section of the coil conductor is configured in a shape such that a dimension thereof in a winding diameter direction of the conical coil is larger than a dimension thereof in the winding axis direction of the conical coil.
