Title:
TRANSMITTING END MAGNETIC CORE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/040533
Kind Code:
A1
Abstract:
Disclosed herein are a transmitting end magnetic core and a preparation method therefor. The transmitting end magnetic core comprises a magnetic core body, the magnetic core body being a flat disk structure; a winding center column is disposed on an end surface of one side of the magnetic core body, the winding center column being used for winding a magnetic induction coil; a winding groove is penetratingly disposed on the magnetic core body, one end of the winding groove being located on the winding center column or the magnetic core body, and the other end penetrating through the edge of the magnetic core body; an outer wall is circumferentially arranged at the edge of the end surface of the same side of the magnetic core body as the winding center column, at least one of two end portions of the outer wall along the circumferential direction of the magnetic core body disposed separated from the winding groove; and the end surface of the magnetic core body is smoothly connected to the side surface of the magnetic core body. The end surface of the magnetic core body of the transmitting end magnetic core disclosed in the present application is smoothly connected to the side surface of the magnetic core body, so that no damage is caused to an insulation layer of a wire; this eliminates a positioning groove on the back surface of the magnetic core body, simplifying a processing technique for the transmitting end magnetic core, and improving the yield of the transmitting end magnetic core.
