Method for manufacturing common mode inductor

The invention discloses a method for manufacturing a common mode inductor, comprising the following steps: S1 of manufacturing of a skeleton: the skeleton comprises a concentric-square-shaped base, the top four corners of the concentric-square-shaped base are provided with columns, and the columns and the concentric-square-shaped base are in integrated structure; S2 of manufacturing of a magneticcore; S3 of assembly: the magnetic core is installed inside the skeleton and clamped by the columns; two coils are wound around the magnetic core and the skeleton, and are respectively located on bothsides of the magnetic core, and the coils wrap the skeleton and the magnetic core together; S4 of soldering: pins are soldered at the bottom four corners of the concentric-square-shaped base, and areconnected to the coils; and S5 of package: the common mode inductor after assembling and soldering is packaged. No need to be separately fixed, the skeleton and the magnetic core provided by the invention are directly fixed to
