Abstract
A magnetic path is formed of a center core disposed inside a first coil and second coil, a first side core and second side core disposed outside the first coil and second coil and coming into contact with the center core, and a magnet disposed between the first side core and second side core, wherein a shape of a space formed by a portion of contact between the first side core and second side core is a shape that forms an insertion portion of the magnet disposed obliquely with respect to the magnetic path, and voids perpendicular with respect to the magnetic path at either end portion of the magnet.
Claims4
An ignition coil, comprising:
- a center core disposed inside a first coil and second coil;
- a first side core and second side core disposed outside the first coil and second coil and coming into contact with the center core;
- and
- a magnet disposed between the first side core and second side core,
- thereby forming a magnetic path passing through the center core, the first side core and second side core, and the magnet, wherein
- the first side core and second side core form a space at a portion of contact between the two, and a shape of the space is a shape that forms an insertion portion of the magnet disposed obliquely with respect to the magnetic path, and voids perpendicular with respect to the magnetic path at either end portion of the magnet,
- wherein a first end of the first side core comes into contact with a first end surface of the center core portion and a first end of the second side core comes into contact with a second end surface of the center core portion, the second end surface being opposite to the first end surface.
