[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0031] This application proposes a frame for inductors that serves as insulation and support while also facilitating automated assembly. To achieve these objectives, the frame features easy positioning. For better illustration, [details omitted]. Figure 1 The following description uses other embodiments as examples. Figure 1 The structure described herein does not limit the scope of protection of this application.

[0032] See Figure 1The inductor 10 includes a base 101, an insulator 102, a core 103, a winding (coil) 104, and a rectangular magnetic ring 105. Assembling these components forms the inductor 10. Given a fixed number of turns in the winding, a core 103, and a rectangular magnetic ring, the inductor's electrical parameters, such as inductance, quality factor, and DC resistance, are also fixed. The base and insulator form the inductor's skeleton, providing support and insulation.

[0033] This application discloses an inductor frame, including a base 101 and an insulator 102. For details, see [link to details]. Figure 2 The base 101 is generally rectangular in shape and symmetrical about axes 11 and 12, which are orthogonal. This axially symmetrical or centrally symmetrical structure facilitates easy placement and removal during mechanized automated assembly processes, eliminating the need to distinguish between left and right orientations. Furthermore, symmetrical notches 1011 are provided on corresponding sides of the base for easy positioning and placement. Symmetrical grooves 1012 are constructed on the adjacent edge of the notches 1011 within the plane 101a of the base 101. This structure serves to fix and position the base, while also saving material and reducing its weight.

[0034] See Figure 2 and Figure 3 The inner side of the plane 101a of the base 101 has a contoured surface 1013 that matches the shape of the winding. In this embodiment, the contoured surface is a concave arc surface, which can accommodate part of the winding, serving a positioning and stabilizing function, and can also reduce the overall height of the inductor to a certain extent. It is understood that the contoured surface matches the winding, which can be a circular winding, a rectangular winding, or an elliptical winding; similarly, the contoured surface matches it to ensure the stability of the assembly between the winding and the base.

[0035] An annular groove 1014 for accommodating the insulating member 102 is constructed on the outer side of the contoured surface 1013. The annular groove is located between the groove 1012 and the contoured surface 1013. The insulating member mates with the annular groove, increasing the overall stability.

[0036] See also Figure 3 Platforms 1015 are formed on both sides of the contoured surface 1013. Pin holes 1016 are constructed at both ends of the platforms along the long axis for the free ends of the windings to pass through. To facilitate automated assembly, the pin holes are close to the annular groove 1014, and the two ends of the platforms are constructed with beveled surfaces 1017 to guide the free ends of the windings smoothly into the pin holes 1016.

[0037] In some embodiments, an elongated groove 1018 is provided on the platform 1015, which can reduce the weight of the base 101 to a certain extent and save materials.

[0038] In some embodiments, the platform 1015 is provided with an elongated protrusion 1019 for assembly positioning and can also fix the winding.

[0039] The inductor frame proposed in this application includes a base 101 and an insulator 102. A structural diagram of the insulator is shown in Figure 4. The insulator 102 is a one-piece molded structure, forming a first space 1021 for accommodating the winding by adjacent surfaces 102a and 102b. The horizontal cross-section of the insulator 102 is rectangular and mates with an annular groove 1014 on the base 101.

[0040] An opening 1022 is formed on the opposite surface of the insulating member 102, such as surface 102b, for the central core 103 to pass through. The thickness of the surface of the insulating member matches the annular groove 1014 of the base 101.

[0041] In some embodiments, the top of the opposite surface of the insulating element, such as surface 102b, is slightly higher than the adjacent surface. This structure ensures easy handling and placement during mechanized automated assembly processes and facilitates the differentiation of surfaces with holes.

[0042] During assembly, the base 101 can be fixed, and then the insulating component 102 can be placed in the annular groove 1014 of the base. The winding 104 can be assembled into the first space 1021 of the insulating component, and the free end of the winding passes through the pin hole 1016 of the base. Then, the central core 103 passes through the hole 1022 of the insulating component and the winding 104. Finally, the rectangular magnetic ring 105 is assembled onto the base. The rectangular magnetic ring is sleeved on the outside of the insulating component 102. The insulating component 102 completely isolates the winding 104 from the rectangular magnetic ring 105 and provides support for the winding and the central core. Finally, the complete inductor device is formed by gluing or soldering.

[0043] It should be noted that the aforementioned central core 103 is cylindrical, and the hole 1022 on the insulating component 102 matches the central core 103. The cross-section of the central core may also include square, elliptical, rhomboid or irregular structure, and the hole on the insulating component is adjusted accordingly.

[0044] In some embodiments, the four sides of the insulating member 102 can also be a separate structure, with each side being independent, which can accommodate bases 101 of different lengths and sizes.

[0045] This application also proposes another insulating element, see [link to relevant documentation] Figure 4b The insulating component 202 has a split structure on the left and right sides and its cross-section is U-shaped. The surface 202a partially wraps the winding. The rest of the structure is the same as the insulating component 102 in the above embodiment. The split structure design can adapt to bases 101 of different lengths. After assembly, it can be completely isolated by insulating material, which improves the applicability of the insulating component.

[0046] This application also proposes another insulating element, see [link to relevant documentation] Figure 4c Compared with the insulating member 102 in the above embodiment, the insulating member 302 is divided into upper and lower split structures. The upper part has a half hole on the opposite surface 302b and matches the half hole on the opposite surface 302b of the lower part, which is used to wrap the central column magnetic core 103 so that the winding 104 is completely isolated from the rectangular magnetic ring 105.

[0047] In some embodiments, the lower portion of the insulating element may also be integrally formed with the base 101. This reduces the number of steps in the automated assembly process.

[0048] This application also proposes another insulating element, see [link to relevant documentation] Figure 4d Compared with the insulating member 102 in the above embodiment, the insulating member 402 is divided into upper and lower split structures, and one side face is omitted. The upper part has a half hole on the opposite face 402b and matches the half hole on the opposite face 402b of the lower part, which is used to wrap the central column magnetic core 103. The side can be completely isolated by setting insulating material, which improves the applicability of the insulating member.

[0049] In some embodiments, the lower portion of the insulating member 402 may also be integrally formed with the base 101. This reduces the number of steps in the automated assembly process.

[0050] It should be noted that due to the structural differences of the insulating components, adjustments can be made during the assembly process based on common assembly methods. For example, if the insulating component is a split structure with the lower part integrally formed with the base, the upper part can be assembled last and then fixed by gluing or soldering.

[0051] The above embodiments are assembled to form the corresponding inductor device.
