The coils are as shown in Figures 1A, 16, 1C and 1D. Attached to a circuit board 12, it includes a body 14 from which the first electrode 16 and the second electrode 18 extend and are respectively connected to the solder joints 20, 22 on the circuit board. The coil 1 is formed by a vertical flat wire having a right-angled cross section, and the coil is spiraled, has a plurality of turns 30, and includes an inner end 26 and an outer end 28, and a first lead 16 is included. The lead frame 32 of the second wire 18 is spliced with the two ends 34, 38 and the inner end 26 and the outer end 28 of the coil 24, and then the wires 16 and 18 are welded. The coil 24 is placed in a mold, and a magnetic powder material is injected into the mold. After demolding, the portion of the lead frame 32 is cut to obtain the inductance of the U.S. patent. However, the US Patent No. 6,204,744B1 has the following defects: 3 M420809 1. If the coil component is wound by a flat wire, the winding of the flat wire takes into account that the two free ends of the coil are located at the coil. When it is external, its winding process is more complicated. 2. If the coil component is wound by a circular wire during manufacture, as shown in Fig. 1D, the multilayer structure of the pattern wire is difficult to meet the requirements of light, thin, short, and small electronic components, and the cost thereof is relatively increased. 3. At the time of manufacture, the coil component is first welded to the wire, and then placed in the casting mold, and then the magnetic powder material is placed in the mold, thus, the coil component and the coated magnetic material are less likely to be completely tightly bonded. problem. 4. Because the number of overlapping turns of the coil wire is high, the electromagnetic interference between the multi-layer wires will cause the loss of the inductance value to be large. There is a 'square; white 1 see power inductors have the above-mentioned missing, this creator is the improvement of the needle X X deficiency research, after long-term research, the end of this creation [new content] component I two creations is intended to provide a Power inductors, their coils are wound with special wires, so there is no need to consider the problem of the two “ends and ends of the special guide islands. The process is relatively simple.” 囤美囤ί: This kind of power inductor, The coil component will not be wound with a round wire as in the US patent case, which will make it difficult to obtain the requirements of thinness, shortness, and smallness. This is the second purpose of the creation. The date is in line with the current electronic components. The formation of this power inductor can be greatly reduced. The coil components are not soldered first, and the watch is not covered with magnetic powder material, that is, the coilless component and the coated magnetic material are not completely closely attached. The problem is this one; another purpose of the 。 。 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 依 功率 依Loss Small, this is another purpose of the creation. As for the detailed structure, application principle, function and power of this creation, it can be fully understood by referring to the following description according to the drawings. [Embodiment] As in the first eight, 16.1〇1/74431, US, No. 6/2〇4/74431, the power inductor, its structure and its absence have been described above, and will not be repeated here. As shown in Figures 2A and 2B The first embodiment of the present invention includes a lower substrate U, a coil 12 disposed on the lower substrate, an intermediate layer 13 ′ surrounding the coil 22, and a middle portion disposed therebetween. The upper substrate 14 above the layer; wherein the lower substrate 11 is a magnetic substrate' is preferably a slab-like body sintered by a ferromagnetic substance; the coil 12 is wound with a surface-insulated wire to wrap the M420809 1 _ blade The wire can be a flat wire, a round wire or the like, and the winding can form a spiral coil extending outward from the center, or a state in which the multilayer winding wires overlap each other, since the coil 12 is a wire Continuously wound, it has two The free end 'two free ends 12A, 12B extend in different directions. The intermediate layer 13 covered with the coil 12 is composed of a ferromagnetic substance powder and an adhesive having a suitable thickness and applied to the lower substrate 1 The coil 12 is completely covered, and only the ends of the two free ends 12A, 12B of the coil 12 are exposed on the side of the intermediate layer 13; above the intermediate layer 13, an upper substrate 14 is provided, and the upper substrate 14 is the same as the lower substrate 11 The magnetic substrate is preferably a sheet-like body sintered by a ferromagnetic material. This constitutes the first embodiment of the power inductor body. As shown in FIG. 2C, in implementation, the power inductor An electrode 15 and 16 are respectively formed on both end faces of the body, and the electrodes 15 and 16 are respectively in contact with the ends of the two free ends of the coil 12, so that the electrodes 15, 16 and the coil 12 can be turned on, and the electrodes 15 and 16 can be Form a surface adhesive type. [Second Embodiment] As shown in Figs. 3A, 3B and 3C, the second embodiment of the power inductor body of the present invention is similar to the power inductor body of the first embodiment described above, but Without the upper substrate, the structure of the power inductor body of the second embodiment can increase the thickness of the intermediate layer 13, so that the intermediate layer 13 and the lower substrate M420809 11 and the upper substrate 14 have the same material. The same effect is also achieved. [Second embodiment] As shown in FIGS. 4A, 4B and 4C, the third embodiment of the power inductor body of the present invention is constructed in accordance with the second embodiment. The power inductor body is similar, but the lower substrate is not provided. In the configuration of the power inductor body of the third embodiment, the thickness of the intermediate layer 13 can be further increased, such that the intermediate layer 13 and the lower substrate 11 and the upper substrate are 14 is the same material, so it has the same effect' is understandable. As can be seen from the above, the power inductor of the present invention is indeed simpler to manufacture, and the manufacturing is more subtle. ^Feng Heyi is more safe when it is known, and these effects can be changed. θ, whitening see power inductor Disadvantages, and its j has not been publicly used, and it is in line with the provisions of the special and profit-seeking laws. < The person who is required to give special permission to Chen Ming, the above-mentioned example, if the better specific stain effect is made according to the idea of this sword, it still does not go beyond the specification and the change of the title, and the merits of its creation are in this creation. In the scope of the eight + Θ not covered spirit, should be & in Chen Ming. M420809 [Simple description of the diagram] The picture shows US Patent No. 6,204,744 B1
