Claims15
A magnetic device comprising:
- a winding having a rectangular shape when viewed from an axial direction of the winding;
- and
- combined insulators that form a rectangular shape surrounding four sides of the winding when viewed from the axial direction of the winding,
- wherein the combined insulators include:
- a first L-shaped insulator being in direct contact with two sides of the rectangular shape of the winding;
- and
- a second L-shaped insulator being in direct contact with two sides of the rectangular shape of the winding, and
- the combined insulators have a first gap at a first corner of the rectangular shape of the combined insulators located at a first corner of the rectangular shape of the winding.
