[0002] Inductors are components that convert electrical energy into magnetic energy and store it. They are widely used in a variety of electronic products, including aerospace, aviation, communications, and household appliances. An inductor typically consists of a bobbin, windings, a shielding cover, packaging materials, and a magnetic or iron core. Inductor bobbins in existing technology typically have pins. There are two main production methods: 1. During the integral injection molding of the inductor bobbin within a mold, the pins are placed within the mold, forming the inductor bobbin and pins as a single piece; 2. After the inductor bobbin is injection-molded, the pins are soldered to the inductor bobbin.

[0003] In view of this, an inductor frame is disclosed in the patent document with application number 201820184958.4. The inductor frame in the above-mentioned prior art has a large side width of the base 3 (i.e., the side width of the base 3 in the present application). Figure 6 The winding base 41 is arranged in a rectangular structure, and the height of the winding clamp 42 is equal to the height of the winding base 41. Due to the influence of the tension when hanging the wire, the overall breakage rate reaches 3%. Utility Model Content

[0005] The technical solution adopted by the utility model to solve the above problems is: the patch skeleton is arranged in an I-shaped structure, which includes a skeleton body, a top plate, a base and a winding structure, the top plate and the base are respectively fixed at two ends of the skeleton body, the winding structure is fixed on the base, the skeleton body is provided with a skeleton through hole, the top plate is provided with a top plate through groove, the base is provided with a base through groove, the two ends of the skeleton through hole are respectively connected with the top plate through groove and the base through groove. Its structural characteristics are: the winding structure includes a winding seat, a winding clamping platform, a winding clamping slot and a wire entry slot, the winding seat is fixed on the side of the base, the winding clamping platform is fixed on the winding seat and forms a winding clamping slot, the wire entry slot is arranged on the base, and the wire entry slot is located above the winding seat; the winding seat includes a trapezoidal seat and a rectangular seat, the trapezoidal seat is fixed to the rectangular seat, and the winding clamping platform is fixed on the rectangular seat.

[0006] Furthermore, a rounded corner R is provided at the junction of the winding clamping platform and the rectangular seat.

[0007] Furthermore, the length of the skeleton through hole, the length of the top plate through groove, and the length of the base through groove are all equal and are all L.

[0008] Furthermore, the material of the patch skeleton is phenolic plastic.

[0009] Furthermore, the wire entry slot is arranged at an angle.

[0010] Compared with the prior art, the present invention has the following advantages: the side width of the base in the patch frame (ie the side width of the present invention) Figure 6 The L2-L4 in the middle is small, which can reduce the size of the PCB board. In addition, since the upper part of the winding seat is a trapezoidal seat and the lower part is a rectangular seat, and the height of the winding clamp is equal to the height of the rectangular seat, the influence of tension when hanging the wire is small, and the product loss rate can be controlled within 0.5%.
