Description

Technical Field

[0001] The utility model relates to the technical field of ferrites, in particular to a ferrite structure and a ferrite product. Background Art

[0002] Manganese zinc soft ferrite has physical and chemical properties such as high magnetic permeability, low coercive force and low power loss. It is widely used in the automotive industry, mainly used to manufacture high-frequency transformers, sensors, noise filters, etc. As the environmental requirements of the application field increase, the strength requirements for ferrite are also getting higher and higher.

[0003] In order to increase the core strength of existing ferrite products, the wall thickness and leg size of the product are usually increased. However, due to the large density difference at the intersection of the core leg root and the base plate, the core obtained by increasing the wall thickness and leg size is prone to cracking during temperature shock verification, and the expected effect is not achieved. For this reason, the design of the fillet at the intersection of the core leg root and the base plate is correspondingly increased. Although the core strength is increased to a certain extent, however, only by increasing the design of a single fillet at the intersection, a single fillet arc surface at the intersection of the core leg root and the base plate still has through cracks, and the crack depth is deep, which does not achieve the expected effect.

[0045] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0046] Combine the following Figures 1 to 14 , describing an embodiment of the utility model.

[0047] According to an embodiment of the present utility model, on the one hand, a ferrite structure is provided, comprising:

[0048] A bottom plate portion 100, a side leg portion 200 extending from at least a portion of a circumferential edge of the bottom plate portion 100 along a first direction away from the bottom plate portion 100, and a center column portion 300 extending from a central area of ​​the bottom plate portion 100 along the first direction away from the bottom plate portion 100;

[0049] The bottom plate portion 100 includes a first surface 10, and the side leg portion 200 and the center column portion 300 each include a second surface 20, and the first surface 10 intersects with the second surface 20;

[0050] See also Figure 2 and Fig.12 As shown, the intersection of the first surface 10 and the second surface 20 forms a first transition angle 30, please combine Figure 3 As shown, the first transition angle 30 is a chamfer C.

[0051] It should be noted that, for the purpose of better explanation and understanding, the terms “low strength”, “medium strength” and “high strength” are used in this article to evaluate the measured results of the core strength.

[0052] The measured results show that in the related art, when the single fillet R at the intersection of the core leg root and the bottom plate is R=0.1mm, a through crack appears at the intersection of the core leg root and the bottom plate, and the core strength is low; when the single fillet R at the intersection of the core leg root and the bottom plate is R=0.3mm, although the core strength is medium, through cracks appear on the arc surface of the single fillet, and the depth of the through cracks is deep. The ferrite structure provided by the utility model forms a first transition angle 30 at the intersection of the first surface 10 and the second surface 20, and the first transition angle 30 is a chamfer C. The measured results show that the ferrite structure provided by the utility model has medium strength, and there is no through crack on the inclined surface of the first transition angle 30.

[0053] The ferrite structure provided by the utility model forms a first transition angle 30 at the intersection of the first surface 10 and the second surface 20, and the first transition angle 30 is a chamfer C, so that a "C"-shaped transition angle structure is formed at the intersection of the bottom plate portion 100 and the side leg portion 200 and at the intersection of the bottom plate portion 100 and the middle column portion 300, thereby avoiding the occurrence of through cracks on the inclined surface at the intersection, improving the degree of cracking at the intersection of the bottom plate portion 100 and the side leg portion 200 and at the intersection of the bottom plate portion 100 and the middle column portion 300, and improving the strength of the ferrite, which is conducive to meeting the application requirements of high-end ferrite products while reducing product costs.

[0054] In some embodiments, see Figure 3 As shown, the length of the right-angled side of the first transition angle 30 along the first direction is C1, and the length of the right-angled side of the first transition angle 30 along the second direction is C2, and C1 and C2 satisfy 0.518≤C2 / C1≤0.718, which can not only effectively avoid the occurrence of through cracks on the inclined surface at the intersection of the first surface 10 and the second surface 20, ensuring the strength of the ferrite, but also help to improve the fluidity of the powder during the preparation of the ferrite.

[0055] Furthermore, in a specific implementation, for example, the value of C2 / C1 may be 0.518, 0.6, 0.618, 0.7 or 0.718.

[0056] In some embodiments, C1 and C2 satisfy C2 / C1=7 / 11. On the one hand, it can effectively avoid the occurrence of through cracks on the inclined surface of the first transition angle 30 at the intersection of the first surface 10 and the second surface 20, thereby improving the strength of the ferrite. On the other hand, it is beneficial to improve the fluidity of the powder during the preparation of the ferrite. On the other hand, it is more conducive to dispersing the stress of the ferrite structure, thereby extending the service life of the ferrite structure.

[0057] In some embodiments, see Figure 5 and Fig.13 As shown, the second transition angle 40 is formed at the intersection of the first transition angle 30 and the first surface 10 and at the intersection of the first transition angle 30 and the second surface 20. The second transition angle 40 is a rounded angle R, thereby forming an "RCR" type transition angle structure at the intersection of the bottom plate portion 100 and the side leg portion 200 and at the intersection of the bottom plate portion 100 and the center column portion 300.

[0058] The measured results show that, in the ferrite structure provided in the present embodiment, the intersection of the first surface 10 and the second surface 20 forms a first transition angle 30, the first transition angle 30 is a chamfer C, and the intersection of the first transition angle 30 with the first surface 10 and the intersection of the first transition angle 30 with the second surface 20 both form a second transition angle 40, the second transition angle 40 is a rounded angle R, the ferrite structure thus obtained has high strength, the inclined surface of the first transition angle 30 has no through cracks, and the intersection of the first transition angle 30 with the first surface 10 and the intersection of the first transition angle 30 with the second surface 20 have no through cracks, which further improves the degree of cracking at the intersection of the first surface 10 and the second surface 20, and further improves the strength of the ferrite.

[0059] In some embodiments, see Figure 5 As shown, the size of the second transition angle 40 is R, and the value range of R is 0.2mm≤R≤0.7mm.

[0060] It should be noted that the value of the dimension R of the second transition angle 40 cannot be too small, otherwise it will not only be difficult to process, but also easily cause through cracks to appear at the intersection of the first transition angle 30 and the first surface 10 and at the intersection of the first transition angle 30 and the second surface 20. Therefore, the value range of R must satisfy R≥0.2mm; the value of the dimension R of the second transition angle 40 cannot be too large, otherwise it will easily cause through cracks to appear on the arc surface of the second transition angle 40. Therefore, the value range of R must also satisfy R≤0.7mm.

[0061] In this embodiment, the second transition angle 40 is formed at the intersection of the first transition angle 30 and the first surface 10, and at the intersection of the first transition angle 30 and the second surface 20. The second transition angle 40 is a rounded angle, and the size of the second transition angle 40 satisfies 0.2mm≤R≤0.7mm. On the one hand, through cracks are avoided from occurring on the inclined surface of the first transition angle 30, and on the other hand, through cracks are avoided from occurring at the intersection of the first transition angle 30 and the first surface 10, and at the intersection of the first transition angle 30 and the second surface 20. On the other hand, through cracks are avoided from occurring on the arc surface of the second transition angle 40, which further improves the degree of cracking at the intersection of the first surface 10 and the second surface 20, thereby ensuring the high strength of the ferrite.

[0062] In some embodiments, see Figure 7and Fig.14 As shown, the intersection of the first transition angle 30 and the first surface 10 and the intersection of the first transition angle 30 and the second surface 20 form a third transition angle 50, and the third transition angle 50 is a chamfer C, thereby forming a "CCC" type transition angle structure at the intersection of the bottom plate portion 100 and the side leg portion 200 and the intersection of the bottom plate portion 100 and the center column portion 300.

[0063] The measured results show that, in the ferrite structure provided in the present embodiment, the first transition angle 30 is formed at the intersection of the first surface 10 and the second surface 20, and the first transition angle 30 is a chamfer. The intersection of the first transition angle 30 and the first surface 10 and the intersection of the first transition angle 30 and the second surface 20 both form a third transition angle 50, and the third transition angle 50 is a chamfer. The ferrite structure obtained in this way has high strength, and there is no through crack on the inclined surface of the first transition angle 30. There is no through crack at the intersection of the first transition angle 30 and the first surface 10 and the intersection of the first transition angle 30 and the second surface 20, which further improves the degree of cracking at the intersection of the first surface 10 and the second surface 20, and further improves the strength of the ferrite.

[0064] In some embodiments, see Figure 7 As shown, the length of the right angle side of the third transition angle 50 along the first direction is C3, the length of the right angle side of the third transition angle 50 along the second direction is C4, and C3 and C4 satisfy 0≤

[0065]

[0066] It should be noted that the length of the hypotenuse of the third transition angle 50 cannot be too large, otherwise it is easy to cause the function of the third transition angle 50 to fail, resulting in the risk of through cracks at the intersection of the first transition angle 30 and the first surface 10 and the intersection of the first transition angle 30 and the second surface 20. Therefore, C3 and C4 satisfy 0≤

[0067]

[0068] In this embodiment, the intersection of the first transition angle 30 and the first surface 10 and the intersection of the first transition angle 30 and the second surface 20 form a third transition angle 50, the third transition angle 50 is a chamfer, and C3 and C4 of the third transition angle 50 meet On the one hand, through cracks are avoided from occurring on the inclined surface of the first transition angle 30, and on the other hand, through cracks are effectively avoided from occurring at the intersection of the first transition angle 30 and the first surface 10 and at the intersection of the first transition angle 30 and the second surface 20, further improving the degree of cracking at the intersection of the first surface 10 and the second surface 20, thereby ensuring the high strength of the ferrite.

[0069] In some embodiments, a third transition angle 50 is formed at the intersection of the first transition angle 30 and the first surface 10, and the third transition angle 50 is a chamfer C; a second transition angle 40 is formed at the intersection of the first transition angle 30 and the second surface 20, and the second transition angle 40 is a rounded angle R, thereby forming a "CCR" type transition angle structure at the intersection of the bottom plate portion 100 and the side leg portion 200 and at the intersection of the bottom plate portion 100 and the center column portion 300.

[0070] Please note that, see Fig. 9 As shown, Fig. 9 The “CCR” type transition angle structure formed at the intersection of the bottom plate portion 100 and the side leg portion 200 is shown. The formation principle of the “CCR” type transition angle structure at the intersection of the bottom plate portion 100 and the center column portion 300 is the same as above and will not be repeated here.

The ferrite structure thus obtained has high strength, and there is no through crack on the inclined surface of the first transition angle 30, and there is no through crack at the intersection of the first transition angle 30 and the first surface 10 and at the intersection of the first transition angle 30 and the second surface 20, which further improves the degree of cracking at the intersection of the first surface 10 and the second surface 20, and further improves the strength of the ferrite.

[0072] It should be noted that, in this embodiment, the length of the hypotenuse of the third transition angle 50 and the size of the second transition angle 40 can be adjusted according to the parameter range in the above embodiment, which will not be described in detail here.

[0074] Please note that, see Fig.11 As shown, Fig.11 The “RCC” type transition angle structure formed at the intersection of the bottom plate portion 100 and the side leg portion 200 is shown. The formation principle of the “RCC” type transition angle structure at the intersection of the bottom plate portion 100 and the center column portion 300 is the same as above and will not be repeated here.
