[0002] As electronic circuits develop towards high frequency, high power density, high reliability and high integration, higher requirements are placed on the ripple, interference and efficiency of electronic circuits. There are many electronic components in electronic circuits, among which inductors mainly play the role of filtering, oscillation, delay and trapping in the circuit. With the development of electronic equipment, people pay more and more attention to the production efficiency and quality of pot-type magnetic core inductors. However, when processing large-sized integral tanks, a large-tonnage press is required for processing and production. Therefore, in order to facilitate processing in production, combined pot-type magnetic core inductors have appeared.

[0003] In the prior art, the can body of the enclosed magnetic core in the combined can-type magnetic core inductor is mostly spliced ​​and needs to be fixed by bonding. However, this bonding splicing has high requirements, increases the complexity of assembly, and thus reduces the production efficiency of the inductor.

[0004] Therefore, a combined pot-type magnetic core inductor with an improved structure is provided to overcome the above-mentioned defects in the prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a combined pot-type magnetic core inductor to solve the problem that the pot body of the existing combined pot-type magnetic core inductor proposed in the above background technology needs to be fixed by difficult bonding, which increases the complexity of assembly and thus reduces production efficiency.

[0048] See also Figure 1-Figure 4 As shown, this embodiment is a combined pot-type magnetic core inductor, comprising:

[0049] A pot-shaped frame 11, in which a magnetic core 12 is arranged;

[0050] A cover plate 14 is covered on the pot-shaped frame 11 to cover the magnetic core 12;

[0051] A fixing column 21 extends from the lower end of the cover plate 14 toward the can-shaped frame 11, and a fixing groove 22 is formed on the fixing column 21;

[0052] in,

[0053] The magnetic core 12 has a hollow through hole 121, and an elastic block 25 is arranged inside the magnetic core 12 near the through hole 121;

[0054] When the fixing post 21 is inserted into the through hole 121 , the elastic block 25 is held in the fixing groove 22 .

[0055] Specifically, the fixing column 21 is detachably disposed at the lower end of the cover plate 14 ; and the outer surface of the magnetic core 12 is wound with a winding 13 .

[0056] It should be noted that the winding 13 is a key part of the inductor, and the current passing through the coil generates a magnetic field; the magnetic core 12 is the core part of the inductor, made of a material with high magnetic permeability, and is used to enhance the magnetic field inside the inductor; the cover plate 14 is installed on the upper surface of the magnetic core 12 and cooperates with the pot-shaped frame 11 to close the magnetic core 12 and protect the winding; the fixing column 21 is used to cooperate with the inner wall of the magnetic core 12 to ensure a firm connection between the cover plate 14 and the magnetic core 12.

[0057] When assembling the pot-type magnetic core inductor, the staff will align the cover plate 14 with the pot-type frame 11 in a positive direction, and insert the fixing column 21 into the through hole 121 inside the magnetic core 12. At this time, rotating the cover plate 14 will synchronously drive the fixing column 21 to rotate. When the elastic card block 25 corresponds to the fixing groove 22, the end of the elastic card block 25 will be inserted into the fixing groove 22 to fix the cover plate 14 and ensure a firm connection between the cover plate 14 and the pot-type frame 11. This step not only realizes the rapid assembly of the pot-type magnetic core inductor and improves production efficiency, but also ensures the stability of the overall structure of the pot-type magnetic core inductor.

[0058] Furthermore, a mounting groove 23 is provided in the middle of the inner wall of the magnetic core 1, and a fixing shaft 24 is installed in the mounting groove 23;

[0059] The elastic block 25 is disposed on the fixed shaft 24 .

[0060] It should be noted that the outer surface of the fixed shaft 24 has a coil spring, which can drive the fixed shaft 24 to rotate, and when the elastic block 25 contacts the outer surface of the fixed column 21, the coil spring is deformed, and when the elastic block 25 is stuck into the fixed groove 22, the coil spring recovers its deformation.

[0061] Specifically, the fixed shaft 24 is clamped in the mounting groove 23 .

[0062] Furthermore, a plurality of fixing grooves 22 are provided along the length direction of the fixing column 21 , thereby being able to adjust the height of the cover plate 14 to a suitable position.

[0063] Specifically, the fixing grooves 22 are evenly arranged along the length direction of the fixing column 21 .

[0064] Furthermore, the tank-shaped frame 11 has:

[0065] Bottom plate portion 111;

[0066] Two symmetrically arranged annular enclosure portions 112, wherein the annular enclosure portions 112 extend from the bottom plate portion 111 toward the cover plate 14;

[0067] A gap 15 is formed between the two symmetrically arranged annular enclosure parts 112 to facilitate the winding operation.

[0068] In order to prevent external electromagnetic interference from appearing through the gap 15 , a slide plate 33 is slidably provided on the outer wall surface of the can-shaped frame 11 , and the slide plate 33 can cover the gap 15 .

[0069] Furthermore, a first track 31 is provided at the outer wall of the lower end of the tank-shaped frame 11;

[0070] and / or

[0071] A second track 32 is provided on the outer wall of the upper end of the tank-shaped frame 11;

[0072] The slide plate 33 slides in the first track 31 and / or the second track 32 , so that the slide plate 33 can move along the first track 31 and the second track 32 .

[0073] When the pot-type magnetic core inductor is assembled, the magnetic core 12 needs to be closed. At this time, the worker only needs to pull the slide plate 33 to slide it inside the first track 31 and the second track 32, and move the slide plate 33 to the outside of the gap 15 to close the gap 15. This step allows the winding to be completely wrapped by the magnetic core, effectively blocking the influence of external electromagnetic waves.

[0074] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
