ROUNDABOUT DURABLE INDUCTOR

WIPO Patent Application WO/2021/109173

A1

The present invention belongs to the technical field of electrical equipment, and in particular to a roundabout durable inductor. The inductor comprises a magnetic ring core, around which an inductive coil is wound. An elastic sleeve is sleeved between the inductive coil and the magnetic ring core. The elastic sleeve is used for reducing the radian of bending of the inductive coil, reducing the abrasion of the inductive coil during winding, guaranteeing the insulation performance, and thereby improving the durability of the inductor. The present invention makes it possible to reduce the winding difficulty of an inductive coil by winding the inductive coil in an arc-shaped slot, and to also reduce sliding of the inductive coil on the magnetic ring core, thereby ensuring that the inductive coil is uniformly and accurately wound at the periphery of the magnetic ring core, and thus improving both the performance and durability of the inductor; in addition, the present invention makes it possible to intuitively check whether the number of turns of the inductive coil is enough, so as to increase the qualified rate of the inductive coil.
