[0002] As technology continues to advance, electronic products are becoming more relevant to our lives. The trend toward thinner, lighter, and more efficient products has led to previously untouched needs and sensory experiences. Magnetic components are one of the key components in electronic products. Reducing the size of magnetic components facilitates their configuration and integration in restricted spaces. With the high efficiency demand in the consumer market, several small-sized magnetic assemblies are closer together, resulting in that more electromagnetic interference is formed therebetween, heat is accumulated easily and needs to be dissipated and noise is amplified. In order to keep each magnetic component in a stable working environment and maintain its lifespan, the technology is becoming more and more stringent.

[0003] At present, in order to solve the problem of noise caused by the vibration of the magnetic components, the common technology is to use soft glue to fill in the magnetic components, which can only absorb a small part of the light vibration. Most of the noise generated by the vibration will still be transmitted to the outside through the soft glue. The soft glue is spread by the compression force of the assembly to fill the area which is expect. In the case of mass production, since the spread direction is not easy to control, the topical area is prone to lack of the soft glue.

[0025] FIG. 1 is a schematic view illustrating a magnetic component according to a first embodiment of the present disclosure. FIG. 2 is a schematic exploded view illustrating the magnetic component according to the first embodiment of the present disclosure. FIG. 3 is a cross-sectional view illustrating a first magnetic part and a second magnetic part according to the first embodiment of the present disclosure. In this embodiment, the magnetic component 1 includes a first magnetic core part 10, a second magnetic core part 20, at least one winding component 30 and at least one elastic gasket 40. The first magnetic core part 10 includes a first groove surface 101. The second magnetic core part 20 includes a second groove surface 201. The second magnetic core part 20 and the first magnetic core part 10 are corresponding and connected to each other to form a chamber 50 therebetween. The at least one winding component 30 and at least one elastic gasket 40 are disposed in the chamber 50. The elastic gasket 40 disposed in the chamber 50 is compressed and fixed through the assembly process of the magnetic component 1, to reduce noise caused by the vibration during operating of the magnetic component 1 and enhance the stability of operating environment at the same time.

[0026] FIG. 4 is a cross-sectional view illustrating the magnetic component according to the first embodiment of the present disclosure. FIG. 5 is a cross-sectional view illustrating the magnetic component according to the first embodiment of the present disclosure. FIG. 6 is a cross-sectional view illustrating an elastic gasket according to the first embodiment of the present disclosure. In this embodiment, the winding component 30 includes a bobbin 303 and a winding L. The elastic gasket 40 is compressed along the first direction z by the assembly process of the magnetic component 1. The original elastic-gasket thickness T (in FIG. 6) is compressed to become the compression elastic-gasket thickness H (in FIG. 5). When the compression elastic-gasket thickness H is less than or equal to fifty percent of original elastic-gasket thickness T, the noise is significantly reduced from the magnetic component 1. It is capable of replacing the soft glue of the prior art to fill the second groove surface 201. In the prior art, the soft glue is dispensed on the second groove surface 201, and then the soft glue is extended externally by the compression force of the first direction z through assembly process of the magnetic assembly 1. Since it is difficult to control the extending direction of the soft glue, the soft glue on the second groove surface 201 is uneven distribution, and the effect of the noise blocking is affected. Notably, there are liquid components contained in the soft glue, and the liquid components will be deteriorated easily by the environment and the time. Preferably but not exclusively, in this embodiment, the elastic gasket 40 is a solid structure. This is designed to cover the second groove surface 201 completely. Since the elastic gasket 40 is compressed to press against the second groove surface 201 during the assembly process, the product yield of the magnetic component 1 can be significantly improved in mass production.

[0027] As shown in FIG. 5 and FIG. 6, in this embodiment, the elastic gasket 40 includes a magnetic-shielding structure 401. Preferably but not exclusively, the magnetic-shielding structure 401 includes one selected from the group consisting of aluminum monoxide, silicon monoxide, magnesium monoxide and a combination thereof. The magnetic-shielding structure 401 includes an outer magnetic-shielding-structure surface 4011. The outer magnetic-shielding-structure surface 4011 is in contact with the bottom bobbin surface 3032 to block leakage inductance while the magnetic component 1 is operating. The magnetic-shielding structure 401 is disposed on the elastic gasket 40 to reduce magnetic flux interference and increase efficiency of magnetic component 1. Since the elastic gasket 40 includes a compression structure 402, when the elastic gasket 40 is compressed, the outer magnetic-shielding-structure surface 4011 is compressed to abut the bottom bobbin surface 3032 more tightly. Consequently, the shielding of leakage inductance is further enhanced.

[0028] As shown in FIG. 5 and FIG. 6. In this embodiment, the elastic gasket 40 includes a magnetic-conductive structure 403. The magnetic-conductive structure 403 includes nanoscale iron core. The magnetic-conductive structure 403 includes an outer magnetic-conductive-structure surface 4031. The outer magnetic-conductive-structure surface 4031 is in contact with the second groove surface 201. Since the effective magnetic part is increased, the magnetic flux of the magnetic component 1 is increased. Furthermore, the magnetic flux is guided into the second magnetic core part 20 due to the characteristics of the material of the magnetic-conductive structure 403. Since the elastic gasket 40 includes a compression structure 402, when the elastic gasket 40 is compressed, the outer magnetic-conductive-structure surface 4031 is compressed to abut the second groove surface 201 more tightly. Consequently, the magnetic conductive efficiency is effectively enhanced.

[0029] Notably, preferably but not exclusively, the elastic gasket 40 is made of composite materials. The magnetic-shielding structure 401, the compression structure 402 and the magnetic-conductive structure 403 are stacked in layers and integrally formed into one piece. In that, the assembly method of the magnetic component 1 is simplified, and the yield of the magnetic component 1 is enhanced.

[0030] Please refer to FIG. 4. In this embodiment, the first magnetic core part 10 includes the first lateral pillar 103, and the second magnetic core part 20 includes the second lateral pillar 203. The first lateral pillar 103 is connected to the first groove surface 101, and the second lateral pillar 203 is connected to the second groove surface 201. The first lateral pillar 103 of the first magnetic core part 10 and the second lateral pillar 203 of the second magnetic core part 20 are corresponding to and connected with each other through a hard glue to form a first lateral body P1. The first lateral body P1 is not only a magnetically conductive structure for the magnetic flux but also a magnetically blocking structure for noise suppression during the operation of the magnetic component 1.

[0031] Please refer to FIG. 2. In this embodiment, the lateral-body groove N of the lateral body P and an elastic-gasket bulge 405 are connected and assembled correspondingly to limit the rotation of the elastic gasket 40. It helps to improve the consistency of quality and the yields of magnetic component 1.

[0032] As shown in FIG. 1 and FIG. 4, the first lateral pillar 103 and the second lateral pillar 203 are connected to form the first lateral body P1 in left side of the magnetic component 1. The lateral pillar 103 and the second lateral pillar 203 are connected to form the second lateral body P2 in right side of the magnetic component 1. Preferably but not exclusively, in other embodiments, the first magnetic core part 10 and the second magnetic core part 20 are in L shape, respectively. Therefore, one of the first lateral body P1 is replaced by another lateral body of the magnetic core part in L shape. One of the second lateral body P2 is replaced by another lateral body of the magnetic core part in L shape. The present disclosure is not limited thereto. In this embodiment, the lateral body P of the magnetic component 1 includes the first lateral body P1 and the second lateral body P2, and a first opening S1 and a second opening S2 are formed and disposed between the first lateral body P1 and the second lateral body P2. The first opening S1 and the second opening S2 are disposed on two opposite side of the magnetic component 1. It facilitates the heat conduction to be changed to heat convection so that the hot air can be exhausted effectively.

[0033] As shown in FIG. 2 and FIG. 3, the elastic gasket 40 includes a through hole 400. The through hole 400 is corresponding in position to the first middle pillar 102 and / or a second middle pillar 202 of the magnetic component 1. When the magnetic component 1 is assembled, the first middle pillar 102 and / or the second middle pillar 202 of the magnetic component 1 are connected with each other accurately by aligning with and passing through the through hole 400. Consequently, the assembly yield is improved.

In this embodiment, the winding component 30a includes a printed circuit board 304 and a winding L. The winding L is embedded in the printed circuit board 304. The winding component 30a is thinner than the winding component 30. Therefore, the magnetic component 1a is more easily to achieve small size and high efficacy. Equivalently, the elastic gasket 40 is disposed in the magnetic component 1a, and the high efficacy is achieved.

In this embodiment, two elastic gaskets 40 are disposed in the magnetic component 1b. One of the elastic gaskets 40 is disposed between the first groove surface 101 and the first winding-component surface 3001, and the other of the elastic gaskets 40 is disposed between the second groove surface 201 and the second winding-component surface 3002. The two elastic gaskets 40 are compressed and fixed by assembly process of the magnetic component 1b to reduce the noise further and increase the practicality of different applications.

The components with same marks indicate the same components, structure and function as that of the above-mentioned embodiments, and are not redundantly described hereinafter. In this embodiment, the elastic gasket 40c of the magnetic component 1c includes two elastic-gasket extended parts 404. The two elastic-gasket extended parts 404 are extended outwardly from the first opening S1 and the second opening S2. More specifically, in view of the first direction z, the elastic-gasket extended part 404 is misaligned with the first magnetic core part 10 and the second magnetic core part 20. The heat that is generated when the magnetic component 1 is operated can be exhausted through the first opening S1 and the second opening S2. Consequently, the elastic-gasket extended part 404 can increase the surface area for cooling. Therefore, the elastic gasket 40 with the elastic-gasket extended part 404 can be used to enhance the stability of the working environment for the magnetic component 1c. In addition, the elastic-gasket extended part 404 is utilized to address the issues that the soft glue has insufficient support in the previous technologies, and the soft glue is not possible to reach an extended structure at the periphery of the magnetic component 1c.

[0037] FIG. 11 is a schematic exploded view illustrating a magnetic component according to a fifth embodiment of the present disclosure. In this embodiment, the magnetic component 1d is similar with the magnetic component 1 shown FIG. 1 to FIG. 6. The components with same marks indicate the same components, structure and function as that of the above-mentioned embodiments, and are not redundantly described hereinafter. In this embodiment, the elastic gasket 40d of the magnetic component 1d has a top surface and a bottom surface, and the top surface and the bottom surface are flat surfaces. The top surface and the bottom surface of the elastic gasket 40d are individually in contact with the second winding-component surface 3002 and the second groove surface 201 more fully and tightly. Furthermore, the elastic gasket 40d is a compressible solid material, so that the shape or profile of the elastic gasket 40d is easy to be adjusted for matching with the profiles of the neighboring assemblies or the working environment. In an embodiment, the top surface and the bottom surface of the elastic gasket 40d are adjusted to an irregular up-and-down surface (as shown in FIG. 8) or a regular wave surface (as shown in FIG. 6). Consequently, the heat dissipation is enhanced, the noise is suppressed, and the magnetic conductivity and magnetic shielding are enhanced.

[0038] FIG. 12 is a schematic exploded view illustrating a magnetic component according to a sixth embodiment of the present disclosure. In this embodiment, the magnetic component 1e is similar with the magnetic component 1 shown FIG. 1 to FIG. 6. The components with same marks indicate the same components, structure and function as that of the above-mentioned embodiments, and are not redundantly described hereinafter. In this embodiment, the elastic gasket 40 of the magnetic component 1 is sandwiched between the two winding components 30. The two winding components 30 have the same structure, but are not limited thereto. Each winding component 30 has a first winding-component surface 3001 and a second winding-component surface 3002 disposed on two opposite sides of the winding component 30. The first winding-component surface 3001 spatially faces the first groove surface 101. The second winding-component surface 3002 spatially faces the second groove surface 201. The top surface of the elastic gasket 40 is corresponding to the second winding-component surface 3002 of the upper winding component 30. The bottom surface of the elastic gasket 40 is corresponding to the first winding-component surface 3001 of the lower winding component 30. The elastic gasket 40 is fastened disposed between two winding components 30. The elastic gasket 40 is compressed by assembly process of magnetic component 1 to be fixed between the two winding components 30. It further provides the efficacy of anti-noise, anti-vibration, shielding against leakage inductance, enhancing magnetic conductivity or heat dissipation, etc., while simplifying the assembly process.

[0039] In summary, the magnetic component 1 of the present invention includes a first magnetic core part, a second magnetic core part, at least one winding component and at least one elastic gasket. The first groove surface of the first magnetic core part and the second groove surface of the second magnetic core part are corresponding to each other and the first magnetic core part and the second magnetic core part are connected with each other to form a chamber therebetween. The elastic gasket in the chamber is compressed by assembly process of the magnetic component to form a sealed space. Consequently, the noise problem caused by the vibration of the magnetic component during operation is addressed and the stability of the magnetic component is enhanced. While the elastic gasket is compressed by assembly process of the magnetic component, the original thickness of the elastic gasket is changed to the compression thickness of the elastic gasket. Consequently, a tight configuration of the magnetic component is achieved. When the compression ratio of the thickness of the elastic gasket is equal to or greater than 50%, a better anti-noise effect is achieved. In addition, the elastic gasket is made of composite materials, and the magnetic-conductive structure, the magnetic-shielding structure and the compression structure are stacked together to form a single unit. Consequently, the procedure of assembling the magnetic component is simplified and the process yield of the magnetic component is enhanced. Furthermore, the elastic gasket of the present disclosure is a solid structure with elasticity. The shape or profile of the elastic gasket is more easily to be adjusted based on the changes of the assembly structure or the assembly method of the magnetic component compared to the soft glue used in the prior arts. In addition, the elastic gasket is made of composite materials that can be adjusted easily for matching with the changes of the environmental factors, which is difficult to be achieved by the prior arts.
