Problems solved by technology

In order to increase the inductance of the electromagnetic coil, the iron core is made as large and as long as possible; however, the hollow section of the skeleton is limited, and the length of the iron core is also limited due to the miniaturization requirements of the device, which makes it difficult to produce high inductance coils. , and in the existing magnetic core, if the right angle is used excessively, the magnetic force line is prone to magnetic force fracture during the divergence process, thus affecting the optimal inductance of the magnetic core

Abstract

The invention provides a soft magnetic ferrite core and a method for manufacturing the same. The soft magnetic ferrite core includes a framework, a wire winding a trunking in the framework, and a magnetic core arranged in the framework; a fixing hole is formed in the framework; the magnetic core is inserted in the fixing hole; the magnetic core includes an installation section which is connected and fixed to the fixing hole formed in the framework, an amplification section which is arranged on one end of the installation section and is used for improving the flux efficiency, and a transition section which is arranged between the amplification section and the installation section, wherein the transition section transits in the manner of a magnetic force line divergent curve rule. The method for manufacturing the soft magnetic ferrite core includes grinding, compressing, sintering, and grinding machining. The soft magnetic ferrite core can improve the inductance of a solenoid coil without increasing the length of the magnetic core, can effectively eliminate sudden change of inner stress of the magnetic core, has high magnetic induction, can perform direct forming on products, effectively avoids the problem that the inner stress is centralized in the prior art, enables more stable inner structures of the products, is low in labor intensity, and is high in working efficiency.

Description

technical field [0001] The invention relates to the field of magnetic flux media of electromagnetic coils, in particular to a soft ferrite core and a manufacturing method thereof. Background technique [0002] The important parameter of the electromagnetic coil is the inductance, and the inductance of the electromagnetic coil is proportional to the quality of the iron core. In order to increase the inductance of the electromagnetic coil, the iron core is made as large and as long as possible; however, the hollow section of the skeleton is limited, and the length of the iron core is also limited due to the miniaturization requirements of the device, which makes it difficult to produce high inductance coils. , and in the existing magnetic core, if the right angle is excessively used, the magnetic force line is prone to magnetic fracture during the divergence process, thereby affecting the optimal inductance of the magnetic core. Contents of the invention [0003] The techni...
