Description

Technical Field

[0001] This utility model belongs to the field of inductor potting, specifically, it relates to an inductor potting structure. Background Technology

[0002] As the current flowing through an inductor increases, the inductor releases enormous energy during normal use or when a fault occurs. The inductor structure cannot absorb this energy, causing the inductor to burst. Typically, insulating glue is encapsulated in the gap between the inner and outer cylinders of the inductor to protect the inductor from energy release. However, due to the narrow gap between the inner and outer cylinders, the sealing effect of the insulating glue is poor and inefficient, resulting in incomplete sealing and air bubbles.

[0003] To address the aforementioned issues, patent document 203366989U discloses an inductor sealing device, comprising a base and a glue-brushing plate located on the base. The base and the glue-brushing plate are equipped with a card holder and an inductor card strip that can be moved within the card holder. The inductor card strip has several inductor slots. Before the sealing operation, this inductor sealing device can remove the inductor card strip and sequentially place each inductor into the inductor slot on the inductor card strip. Then, the inductor card strip is placed under the card holder, and the glue-brushing plate is pressed onto the card holder and glue is applied to the glue-brushing plate. This allows the glue to be evenly applied to the terminals at one end of the inductor, but it cannot solve the aforementioned problems. Utility Model Content

Its purpose is to provide an inductor potting structure that facilitates the encapsulation of high-current inductors, improves encapsulation effect and efficiency, and avoids incomplete encapsulation leading to blistering.

Detailed Implementation

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0018] Figure 1 This is a schematic diagram of the structure of the inductor body in an embodiment of this utility model; Figure 2 This is a schematic diagram of the inductor potting structure in an embodiment of this utility model.

[0019] like Figure 1 and Figure 2 As shown, the inductor potting structure provided by this utility model includes an inductor body 10, a vacuum assembly 20, and an adhesive injection assembly 30. The vacuum assembly 20 is connected to one side of the inductor body 10, and the adhesive injection assembly 30 is connected to the other side of the inductor body 10. The inductor body 10 includes an outer cylinder 11 and an inner cylinder winding 12. The diameter of the inner cylinder winding 12 is slightly smaller than the inner diameter of the outer cylinder 11, so that a cavity 14 is formed between the outer cylinder 11 and the inner cylinder winding 12. The cavity 14 can be used to pot insulating adhesive. The vacuum assembly 20 can draw a vacuum into the cavity 14 between the outer cylinder 11 and the inner cylinder winding 12 of the inductor body 10, thereby cooperating with the adhesive injection assembly 30 to draw the insulating adhesive into the cavity 14 between the outer cylinder 11 and the inner cylinder winding 12, completing the encapsulation of the inner cylinder winding 12, improving the encapsulation effect and efficiency, and effectively avoiding the problem of incomplete encapsulation leading to blistering.

[0020] The inductor body 10 also includes a cover plate 13, which is adapted to the outer cylinder 11. The two cover plates 13 are respectively disposed at both ends of the outer cylinder 11 to further encapsulate the inner cylinder winding 12. The two ends of the inner cylinder winding 12 are provided with connecting pieces 121. The two cover plates 13 are provided with connecting holes 131 adapted to the connecting pieces 121. The connecting pieces 121 extend from the connecting holes 131 on both sides, so as to facilitate the connection of the inductor to the circuit and facilitate the use of the inductor.

[0021] The cover plate 13 at one end of the outer cylinder 11 is provided with a first threaded hole 132, which can be used to connect the vacuum assembly 20; the cover plate 13 at the other end of the outer cylinder 11 is provided with a second threaded hole 133, which can be used to connect the impregnation assembly 30. Both the first threaded hole 132 and the second threaded hole 133 are connected to the cavity 14.

[0022] The vacuum assembly 20 includes a vacuum tube 21, a first threaded connector 22, and a vacuum pump 23. The first threaded connector 22 is located at one end of the vacuum tube 21, and the vacuum pump 23 is located at the other end of the vacuum tube 21. The first threaded connector 22 is screwed into the first threaded hole 132, so that the vacuum pump 23 can draw a vacuum into the cavity 14 through the vacuum tube 21, thereby creating a negative pressure in the cavity 14. This allows the insulating adhesive to be drawn into and encapsulated in the cavity 14, resulting in a good encapsulation effect and high efficiency, effectively avoiding the problem of incomplete encapsulation leading to blistering.

[0023] The glue injection assembly 30 includes a glue injection tube 31, a second threaded connector 32, and a glue bottle 33. The second threaded connector 32 is located at one end of the glue injection tube 31, and the glue bottle 33 is located at the other end of the glue injection tube 31. The second threaded connector 32 is screwed into the second threaded hole 133. The glue bottle 33 stores insulating glue. Under the action of negative pressure in the cavity 14, the insulating glue can enter the cavity 14 through the glue bottle 33 and the glue injection tube 31, thereby quickly completing the potting and sealing of the cavity 14.

[0024] By screwing the first threaded connector 22 into the first threaded hole 132 and the second threaded connector 32 into the second threaded hole 133, the vacuum component 20 and the glue injection component 30 can be quickly connected, thereby further completing the potting and encapsulation of the inductor body 10 and improving production efficiency.

[0026] The inductor potting structure provided by this utility model includes an inductor body 10, a vacuum assembly 20, and a glue injection assembly 30. The vacuum assembly 20 is connected to one side of the inductor body 10, and the glue injection assembly 30 is connected to the other side of the inductor body 10. The inductor body 10 includes an outer cylinder 11 and an inner cylinder winding 12. The diameter of the inner cylinder winding 12 is slightly smaller than the inner diameter of the outer cylinder 11, so that a cavity 14 is formed between the outer cylinder 11 and the inner cylinder winding 12. The cavity 14 can be used to pot insulating glue. The vacuum assembly 20 can encapsulate the inductor body 10. The cavity 14 between the outer cylinder 11 and the inner cylinder winding 12 is vacuumed, thereby cooperating with the glue injection assembly 30 to draw insulating glue into the cavity 14 between the outer cylinder 11 and the inner cylinder winding 12, completing the encapsulation of the inner cylinder winding 12, improving the encapsulation effect and efficiency, and effectively avoiding the problem of voids caused by incomplete encapsulation.
