[0036] The working principle of a differential mode inductor core frame provided by the utility model is as follows:

[0037] Step 1: First, when assembling the inductor, the enameled wire is wound around the outside of the winding rod 4 and the winding rod 4 is sleeved inside the limiting groove 3. At this time, the No. 1 clamping column 6 is sleeved inside the clamping groove 7, so that the clamping groove 7 can limit and fix the fixing frame 5 on the top of the limiting frame 2 through the No. 1 clamping column 6, and then the winding rod 4 can be squeezed and fixed inside the limiting groove 3, thereby achieving the effect of fixing and installing the winding rod 4 after winding, thereby avoiding the problem of difficulty in winding after the winding rod 4 is fixed, thereby bringing convenience to the assembly and processing of the inductor. When winding different quantities of enameled wires, the No. 2 clamping column 9 is sleeved inside the adjusting groove 8, so that multiple adjusting grooves 8 can limit the position of the No. 2 clamping column 9, thereby achieving the limiting effect of the position of the closing cover 10, that is The effect of adjusting the distance between the closing cover 10 and the winding rod 4 is achieved, thereby facilitating the positioning and fixing of winding rods 4 of different sizes.

[0038] Step 2: When the temperature inside the closed cover 10 rises, the airflow outside the closed cover 10 can enter the inside of the closed cover 10 through the heat dissipation holes 14, so that the airflow inside the closed cover 10 and the airflow outside the closed cover 10 are quickly exchanged through the heat dissipation holes 14, thereby improving the heat dissipation speed inside the closed cover 10. When assembling and fixing the inductor, the connecting port 151 is sleeved on the outside of the extrusion sheet 152.
