Description

Technical Field

[0001] The utility model relates to the technical field of anti-interference annular amorphous magnetic cores, in particular to an anti-interference annular amorphous magnetic core. Background Art

[0002] With the emergence of amorphous magnetic materials, due to their excellent constant electrical properties and resistance to DC bias magnetism, rolled amorphous cores are gradually being used to make inductor cores. Currently, most amorphous annular cores are made by embedding the rolled amorphous cores in an insulating annular box. There is still a certain gap between the insulating annular box and the rolled amorphous core. The rolled amorphous core in the box is easy to move, which can easily change the magnetic field and make the produced inductor unstable. Moreover, the insulating annular box is made of plastic with relatively high hardness. Since rigid objects can transmit force, when the external coil is wound around the core, the coil will exert a strong effect on the amorphous annular core through the insulating annular plastic box, which can easily cause it to deform, thereby affecting the performance of the core.

[0003] In order to solve the above problems, an amorphous annular magnetic core is disclosed in application number CN201220365122.7, in which a layer of buffer medium is filled between the rolled amorphous annular core and the insulating annular box, so that the rolled amorphous annular core is better fixed, avoiding the change of the magnetic field due to the movement of the rolled amorphous annular core in the box, and making the produced inductor more stable; the surface of the rolled amorphous annular core is covered with a layer of buffer medium, so that when the external coil is wound around the magnetic core, no force is applied to the rolled amorphous annular core, so that the amorphous annular core does not deform, and the magnetic core performance is good.

[0004] Although the amorphous annular magnetic core disclosed in the above patent can be protected by the buffer medium, the box cover is directly stuck at the opening of the annular shell, which is difficult to open with glue sealing and easy to loosen without glue sealing, and the anti-interference effect is poor. Utility Model Content

The anti-interference annular amorphous magnetic core disclosed by the utility model is covered with an anti-interference magnetic ring, has good anti-interference effect, and the anti-interference magnetic ring is located between the limiting lower ring and the limiting upper ring, and the annular upper cover and the limiting upper ring are integrally threadedly installed at the opening of the annular shell, which is convenient for the anti-interference magnetic ring and the annular amorphous magnetic core to be quickly disassembled and recycled, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-interference annular amorphous magnetic core, comprising an annular shell, a limiting lower ring fixedly installed on the lower part of the outer wall of the annular shell, an external thread is opened on the upper part of the outer wall of the annular shell and an annular upper cover is threadedly connected to the annular upper cover through the external thread and the internal thread, an internal thread is opened on the inner wall of the annular upper cover, a limiting upper ring is fixedly connected to the outer edge of the bottom of the annular upper cover, the annular shell is covered with an anti-interference magnetic ring, and the anti-interference magnetic ring is located between the limiting lower ring and the limiting upper ring.

[0007] Preferably, an annular amorphous magnetic core is placed in the annular shell, and a buffer medium is filled in the gap between the annular shell and the annular amorphous magnetic core.

[0008] Preferably, the buffer medium is a solid soft gel.

[0009] Preferably, the buffer medium is liquid glue.

[0010] Preferably, a first sealing ring sheet is adhered to the top of the inner side wall of the annular upper cover, and a second sealing ring sheet is adhered to the upper part of the inner side wall of the inner ring through hole of the annular housing.
