Dongguan Hongheng Electronic Technology Co., Ltd.(www.coils-hhd.com) Reprinted on June 2, 2025:

On April 7, 2025, the financial sector reported that the China National Intellectual Property Administration information showed that Dongguan Hongheng Electronic Technology Co., Ltd. applied for a patent entitled "Low loss, high current, broadband shielded magnetic core device suitable for mobile power supply", with the publication number of CN 119764016 A and the application date of December 2024.

The patent abstract shows that the present invention relates to the field of magnetic core device technology and discloses a low loss, high current, wideband shielded magnetic core device suitable for mobile power supplies, comprising a magnetic core device body. The middle of the magnetic core device body is provided with a central column, and the cross-section of the central column is square and flat. An annular groove is opened between the magnetic core device body and the central column, and the annular groove is rectangular with circular chamfers at the corners. A rectangular notch is opened between the outer wall of the annular groove and the magnetic core device body, and the two magnetic core device bodies can be symmetrically assembled into one. In the present invention, the central pillar set in the middle of the magnetic core device body can wrap the wire, and the wire can be placed through a circular groove, thereby improving the traditional shape of magnetic core devices, which are mostly circular, E-shaped, or can shaped. These shapes may only have semi closed or three-quarters closed shielding structures, which limits their shielding effect and may lead to poor anti-interference ability in practical applications.
