[0002] A soft magnetic core is a component used to assemble a transformer. Soft magnetic is a magnetic material with a powered coil wound on its surface. When the coil is powered, the soft magnetic surface will have a magnetic field. When using a soft magnetic core, the surface of the core body is generally provided with a support frame, which makes it easier to use the soft magnetic core to assemble a transformer.

[0003] The inventors have found in their daily work that the soft magnetic core still has at least the following problems: when using the soft magnetic core, the surface of the core body is generally provided with a support frame, but in actual use, the support frame is generally connected to the core body by glue. When the soft magnetic core needs to be disassembled, the connection parts need to be heated and then the support frame is slowly separated. Because the texture of the soft magnet is relatively brittle, the soft magnet may be broken when the support frame is pulled, which makes it more troublesome to disassemble the soft magnetic core.
