[0017] 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. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0018] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0019] To facilitate understanding, the relevant terms and concepts involved in the embodiments of this application will be introduced below.

[0020] Inductors include vertical and horizontal types, for example... Figure 1The vertical inductor 11 shown has winding leads 111 and 112 extending from both ends of the coil winding, used to connect to external circuits. When the winding leads 112 at the top of the inductor 11 are led to the frame or PCB board at the bottom of the inductor 11 (marked by reference numeral 12), there are technical problems: difficulty in fixing them; contact between the winding leads 112 and the winding; and contact between the winding leads 111 and 112 and the magnetic core when soldering them to the circuit. These technical problems affect the inductance of the inductor and result in an irregular overall appearance after soldering.

[0021] Based on the above description, this application proposes an inductor frame 22, see [link to relevant documentation]. Figure 2 and Figure 3 It includes a base 221 and a column bracket 222 disposed on the side of the base 221, which is used to guide and fix the winding lead and to isolate the winding lead from the winding.

[0022] In some embodiments, the base 221 has symmetrically arranged ears 221a for the winding leads to pass through. Preferably, one ear 221a is located on the outer side of the column support 222. The ear 221a has a through hole 221b. The through hole 221b matches the winding lead; for example, when the winding lead is a flat wire, the through hole is a flat hole; when the winding lead is a round wire, the through hole is a round hole. When soldering the winding leads to pins or circuits, this structure ensures that the winding leads are relatively fixed, facilitating soldering.

[0023] In some embodiments, flanges 221c are provided circumferentially on the side of the base 221. The flanges 221c and the base 221 form an opening space 221d for enclosing part of the magnetic core. For example, the bottom of the magnetic core of the vertical inductor is housed in the opening space 221d. This facilitates assembly and fixation during manual or mechanized assembly and completely isolates the magnetic core from the circuit.

[0024] It should be noted that this application does not limit the material requirements of the magnetic core, and it can be a ferrite core, a nickel-zinc core, a manganese-zinc core, an iron-silicon-aluminum core, an amorphous nanocrystalline core, etc.

[0025] In some embodiments, the shape of the base 221 matches the cross-sectional shape of the inductor core, for example, including rectangle, circle, polygon, etc. Figure 2 The example given is a rectangle, but this application does not impose any limitations on it.

[0026] The column bracket 222 is located on the side of the base 221. The column bracket 222 and the base 221 are integrally formed. As the skeleton of the inductor, its material includes plastic, ceramic or bakelite, etc., and can be formed by injection molding, sintering or pressing.

[0027] In some embodiments, the side of the column support 222 near the base 221 is provided with an arc surface 222a that matches the shape of the winding, in order to absorb the space occupied by the winding protruding the magnetic core.

[0028] In some embodiments, the column support 222 has a notch 222b at the top for the winding lead at the top of the winding to pass through and be confined within the notch 222b.

[0029] In some embodiments, the side of the column bracket 222 away from the base 221 is provided with a groove 222c, the groove 222c is connected to the ear hole 221b of one of the ears 221a, and the winding lead can be disposed in the groove 222c and pass through the ear hole 221b of the ear 221a connected thereto.

[0030] In some embodiments, the top of the column support 222 is flush with the top of the magnetic core, such as... Figure 4 As shown.
