Claims

[Scope of utility model registration request]

A bobbin consisting of a rectangular cylindrical winding core with rectangular donut plate-shaped flanges at both ends, a coil wound around the bobbin, a ferrite core to which the bobbin is attached, and a top of the coil. In a high-frequency transformer having an insulating plate that insulates between layer surfaces, the insulating material includes a first part that covers one surface of the winding core, and the upper and lower parts of the first part are respectively connected to the winding core through mountain fold lines. A fourth part is connected to the upper part of the second part and the lower part of the third part through a mountain fold line and covers half of the remaining surface of the winding core part. and a fifth part, and sixth and seventh parts connected to both sides of the two parts via valley fold lines, having vertical dimensions twice as large as the second part, and disposed on the inner surface of each of the flange parts. and eighth and ninth parts connected to both sides of the third part via valley fold lines, having vertical dimensions twice as large as the third part, and disposed on the inner surface of each of the flange parts. , a tenth part and an eleventh part are connected to the outside of each of the sixth part and the seventh part via valley fold lines, and cover the upper surface of the coil wound around the bobbin in two layers to insulate the coil from the ferrite core. and a twelfth part that is connected to the outside of each of the eighth part and the ninth part via valley fold lines and covers the upper surface of the coil wound around the bobbin in two layers to insulate between it and the ferrite core. 13. A high-frequency transformer comprising a thirteenth part, and formed of a sheet of insulating paper that forms a horizontally long rectangular shape in an unfolded state.
