Title:
MAGNETIC COUPLING INDUCTOR AND ASSEMBLY METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/188026
Kind Code:
A1
Abstract:
[Problem] In a magnetic coupling inductor in which two installed inductors are caused to operate in interleave, to facilitate adjustment of a leakage inductance value and, in such adjustment, to ensure the dimensional accuracy of terminal pin intervals of both terminal blocks and the rigidity of a winding shaft part of a bobbin. [Solution] The present invention comprises a ring-shaped spacer member 5 which is split in the circumferential direction and attached to a bobbin 4 in a circumferential direction of a winding shaft part (42) through which a middle leg part (11, 21) is inserted. The spacer member comprises: a cylinder section (5C) on which an annular third core 3 (3A, 3B) is placed; and flange sections 5A, 5B provided at both ends thereof. The third core 3 is split in the circumferential direction and mounted on the outer periphery of the cylinder section (5C) of the spacer member 5 in a state in which, of elements of the shape of the third core 3 and the material characteristic of the third core 3, the magnitude of at least one of the elements is set so that a desired leakage inductance value is generated.
