Abstract

The invention relates to a magnetic core structure capable of reducing the insertion loss. The magnetic core structure comprises a magnetic core body and a magnetic core cover body, wherein two sidesof the magnetic core body are respectively provided with a first flange and a second flange in an extending manner, the first flange is provided with a first groove, the second flange is provided witha second groove, and the first groove and the second groove are respectively arranged on the same side surface of the first flange and the second flange; and the magnetic core cover body is adjacentto the first groove and the second groove, and the magnetic core cover body is combined onto the same side of the first flange and the second flange. The magnetic core structure is simple in structureand reasonable in design; and by adopting the magnetic core structure, the overflow rubber can be improved, the parasitic capacitance generated by a coil winding can be reduced, the insertion loss ofa signal can be reduced, the electric (magnetic) characteristics are good, the stability of the product yield can be maintained, and an efficacy can be achieved.

Description

【Technical field】 [0001] The invention relates to a magnetic core structure, in particular to a magnetic core structure capable of reducing insertion loss. 【Background technique】 [0002] Inductor, Common Mode Choke or Transformer are often used in electronic products. In the electronic circuit, it has the functions of resisting current changes, filtering current noise, stabilizing the current value in the circuit, reducing electromagnetic interference (EMI), and power conversion. [0003] In this regard, China Taiwan Patent No. M445243 discloses an "inductance element". The adhesive can be made of thermosetting adhesive, thermoplastic adhesive, silicone adhesive, etc., and an enameled wire is wound on the I-shaped iron core to form an inductance element. [0004] In this technical solution, when the adhesive is used for the bonding (contact surface) between the I-shaped iron core and the cover plate iron core, no matter how much the adhesive is applied, when the I-shaped ...
