Title:
COIL DEVICE AND ELECTRICAL JUNCTION BOX
Document Type and Number:
WIPO Patent Application WO/2020/066563
Kind Code:
A1
Abstract:
A coil device 20 that comprises: a core 30 that is a magnetic body that has a pair of facing walls 32A, 32B that are arranged so as to face and a plurality of leg parts 40 that protrude toward the sides toward which the facing walls 32A, 32B face at different areas of the facing walls 32A, 32B; and a plurality of windings 21 that are wound on the plurality of leg parts 40. In an area that is between the adjacent plurality of windings 21, the facing walls 32A, 32B of the coil device 20 comprise a reduced-diameter part 38 at which the cross-sectional area of the facing walls 32A, 32B in a cross-section that is orthogonal to the direction of the magnetic flux ϕ1 that is generated inside the facing walls 32A, 32B as a result of energization of the windings 21 is smaller.
