Description

Technical Field

[0001] The utility model relates to the technical field of inductors for electronic engineering, in particular to an amorphous large-current anti-interference magnetic ring inductor. Background Art

[0002] An inductor is a crucial component in circuits, primarily used to store electrical energy and control current flow. Its fundamental principle is based on the phenomenon of electromagnetic induction. When current flows through an inductor coil, it generates a magnetic field around it. As the current changes, the magnetic field also changes, generating an induced electromotive force in the inductor that resists the change in current flow.

[0003] In power supplies and signal processing, inductors are often used in filters to remove unnecessary frequency components. Inductors are the basic component of transformers and are used for voltage conversion. In switching power supplies and motor drives, inductors are used to store and release energy.

[0004] An amorphous magnetic ring inductor is an inductor made from amorphous materials (such as amorphous alloys). Compared to traditional crystalline or ferrite materials, amorphous materials have some unique properties that make them excel in certain applications. Amorphous materials generally have higher magnetic permeability, which means they can store more magnetic energy in a smaller volume. Amorphous materials also have lower electromagnetic losses, which can effectively reduce energy loss and improve efficiency, especially in high-frequency applications. Amorphous magnetic ring inductors maintain good performance over a wide frequency range, making them suitable for high-frequency circuits. Due to their high magnetic permeability, amorphous magnetic ring inductors can achieve higher inductance values ​​in a smaller volume, making them suitable for space-constrained applications. Amorphous materials are less sensitive to temperature changes and can maintain stable performance over a wide temperature range.

[0005] In some complex circuits with densely packed electronic components, many need to be close together. Due to the principle of electromagnetic induction, current flowing through a powered circuit generates a magnetic field, which affects the operation of inductors. While multiple inductors are sometimes necessary for mutual induction, in most cases the magnetic field's effect on inductors is negative, leading to signal distortion or current fluctuations. This is particularly noticeable in high-frequency circuits. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , the utility model provides a technical solution:

[0029] An amorphous high-current, anti-interference magnetic toroidal inductor includes a base 2, on which an inductor 5 is mounted. Two sets of solder pins 3 are provided at the bottom of the base 2, extending through the base 2 and electrically connected to the inductor 5. The inductor 5 is wrapped with an insulating layer 4, which is then wrapped with a magnetic shielding layer 1. The two sets of solder pins 3 can be directly soldered to a circuit. This inductor performs all the functions of a conventional inductor and prevents the magnetic field generated by densely arranged circuits from affecting the inductor's operation.

[0030] Furthermore, the insulating layer 4 is made of metal aluminum, and a cavity corresponding to the inductor 5 is defined in the insulating layer 4. Metal aluminum is a non-magnetic material that does not absorb magnetic fields and is not affected by magnetic field forces. It is also inexpensive and can be used as a high-quality insulating material.

[0031] Furthermore, the magnetic shielding layer 1 is made of an iron-nickel alloy and has a cavity defined therein corresponding to the isolation layer 4. The iron-nickel alloy has a very high magnetic permeability and can effectively guide magnetic field lines, concentrating the surrounding magnetic field lines within the magnetic shielding layer, thereby preventing external magnetic fields from affecting the operation of the internal inductor 5.

[0032] Furthermore, the inductor 5 includes a cover 6, an amorphous magnetic ring 7, a coil 8, a fixed plate 9, a mounting post 10, and an insulating housing 11. The mounting post 10 is fixedly connected to the center of the fixed plate 9. The amorphous magnetic ring 7 is sleeved on the mounting post 10. The coil 8 is wound around the amorphous magnetic ring 7. The coil 8 is electrically connected to the solder pin 3. The insulating housing 11 is provided on the outside of the amorphous magnetic ring 7 and the coil 8. The cover 6 is installed on the side of the insulating housing 11 facing away from the fixed plate 9. The insulating housing 11 and the cover 6 must be made of insulating material to prevent the coil 8 from short-circuiting with the external insulation layer 4.

[0033] Furthermore, the mounting plate 9 is provided with positioning bumps 12. Two sets of through-holes are defined at the bottom of the mounting plate 9, through which the ends of the coil 8 pass to electrically connect to the solder pins 3. The positioning bumps 12 and the inductor mounting slots 13 work together to define the position of the mounting plate 9 and prevent the mounting plate 9 from rotating within the inductor mounting slots 13, which could damage the wires.

[0034] Furthermore, the base 2 is provided with an inductor mounting groove 13 corresponding to the fixing plate 9 , and a positioning matching opening 14 corresponding to the positioning protrusion 12 is provided in the inductor mounting groove 13 , and the fixing plate 9 is plugged and installed in the inductor mounting groove 13 .

[0035] Working principle: When using this device, you can use it like a conventional inductor. Just solder the two sets of welding pins 3 to the circuit board and connect them to the circuit. The magnetic field generated by the other electronic components in the dense circuit structure during operation is absorbed and shielded by the magnetic shielding layer 1, and cannot affect the operation of the internal inductor 5.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
