Description

Technical Field

[0001] This utility model relates to the field of filters, specifically a common-mode filter with a sealed packaging structure. Background Technology

[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out a specific frequency point or frequencies other than that frequency point in a power line to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency.

[0003] Traditional filters typically use a 4-pin lead configuration, which generally results in a relatively high profile. However, conventional surface mount technology (SMT) methods cannot meet customer expectations, and achieving the required height does not satisfy the performance requirements. In the current market trend, traditional through-hole and surface mount technologies cannot meet the miniaturization and portability needs of actual products. Therefore, those skilled in the art have provided a common-mode filter with a hermetically sealed package structure to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a common-mode filter with a sealed encapsulation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a common-mode filter with a sealed encapsulation structure, comprising a base, two skeletons symmetrically fixedly connected to the top of the base, and the same LUF16 magnetic core fixedly connected to one side of the two skeletons, and copper wire wound on the outer wall of the LUF16 magnetic core, and two conductive sheets symmetrically fixedly connected to the top of the skeletons, and copper wire can be wound on the conductive sheets.

[0006] As a further improvement of this utility model: slots are provided on both sides of the base, and plugs are inserted through both slots. The tops of the two plugs are fixedly connected to the same top cover. Iron shells are fixedly connected to both sides of the plugs, and the iron shells are adsorbed on the top of the base.

[0007] As a further improvement of this utility model: a magnetic plate is fixedly connected to the bottom of the iron shell, and the magnetic plate is attracted to the top of the base.

[0008] As a further improvement of this utility model: the overall height of the base and the frame is twelve centimeters, and the base and the two frames are U-shaped.

[0009] As a further improvement of this utility model: the top rectangular array of the top cover is provided with multiple rectangular holes, and multiple conductive sheets pass through the multiple rectangles respectively.

[0010] As a further improvement of this utility model: the base is a hollow structure, and the top of the frame and the bottom of the top cover are fitted together.

[0011] As a further embodiment of this utility model: the iron shell and the insert block enclose the LUF16 magnetic core and copper wire inside, and the height of the iron shell is less than the height of the insert block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Align the two plugs with the slots and insert them. The two metal shells will descend and adhere to the top of the base. Multiple magnetic plates will adhere to the top of the base, securing the metal shells. Copper wires can be wound around multiple conductive plates. The top of the top cover has multiple rectangular holes, allowing the plugs to be in the installation state or the conductive plates to be exposed, thus facilitating wiring. The base adopts a hollow design, which effectively reduces the overall weight of the filter. The metal shells, plugs, and top cover are used to protect the LUF16 magnetic core and copper wires inside.

[0014] This utility model is simple to use. This filter achieves ultra-low height and small size for the same power, and the surface mount installation method better matches and meets the requirements of the whole machine to be light and thin. The low height and reduced size not only change the lack of surface mount products with this series of structural designs, but also meet the market demand for miniaturized surface mount development.
