Referring to the figure, the conventional inductor 1 is provided with an I-shaped core 丨1, and the core is wound with a plurality of turns of the wire 1 2 (such as an enameled wire) to form a coil 丨3; The two ends of the crucible 3 are led out to the two electrodes 14 of the core for soldering to a circuit board (pCB) (not shown). When the current on the board passes through the inductor, the coil 13 of the inductor generates a magnetic field that stabilizes the current and removes the noise generated on the board. However, the structure of the conventional inductor 1 , is provided by a 铁-shaped iron core for winding the coil 13, thereby generating an inductive effect; however, the processing procedure of the winding of the coil 13 is complicated.

The reason is that the ends of the I-shaped iron core 11 are closed and the middle is slender, and the coil 13 that is wound beforehand cannot be directly placed on the 形-shaped core ,, but must be on each of the iron cores 11, one by one. The coil 丨3 is wound around; that is, if the iron core 11 is not provided, the winding of the coil 13 cannot be performed, resulting in prolonged man-hours during production, and product defects are likely to occur during production operations. Further, the I-shaped core U of the conventional inductor 1G is supported at both ends by the intermediate elongated mandrel portion, and its strength is insufficient. In addition, in order to increase the strength and reduce the electromagnetic interference, the conventional inductor must be disposed outside the coil 13 as shown in FIGS. 2 and 3) to suppress electromagnetic interference and shield the outer cover 15 (thus, increase) 5 M304761 Difficulties and costs of production [New content] The creator has provided the novel inductor structure in view of the shortcomings of the conventional inductor structure described above, in order to eliminate the defects caused by the prior art. An inductor structure is provided to simplify assembly process, improve strength, and reduce electromagnetic interference. According to the above object, the inductor of the present invention is provided with a flat core body and a coil, wherein one side of the body is an open surface. The other side is a closed surface; the open mask has a groove, and the center of the groove is provided with a convex column, and the groove and the protruding column are matched with the shape of the coil and the through hole formed by the central portion thereof. The open end can be directly assembled into the groove and the stud of the body, that is, the inductive state is formed. The assembly is simple, and the strength of the inductor can be improved according to the closed surface of the body itself. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings. Figures 4 and 5 respectively A planar exploded view and a side cross-sectional view of a preferred embodiment of the novel inductor structure are shown. As shown in the drawings, the novel inductor mainly includes a flat core body 20 and a coil 30. 20—the mask has a recess 21, and a recess 22 is formed in the center of the recess 21. The recess 21 and the post 22 respectively correspond to the outer shape of the coil 3〇 and the through hole 31 formed at the center thereof. The body 2 has a groove 21 and a protrusion 6 M304761 • the column 22 forms an open surface 23; the other opposite surface of the body 20 forms a closed surface 24. The open surface 23 of the body 20 is in the corresponding groove 21 An electrode 25, 26 is provided on each of the two sides as a lead end of the coil 30, and is used for soldering with other objects such as a circuit board (not shown). The coil 30 is wound by a wire such as an enameled wire or the like. Completed coil 30' has a through hole 31 formed in its central portion. Since the body 20 has an open face 23, the coil 30 can be allowed to be placed into the recess 21 of the body 20 from the open face 23; thus, the coil 30 can be wound in a large amount. After the system is assembled, the coil 3〇 is simply placed in the recess 21 of the body 2〇, and the coil 3〇 does not have to be wound with the body 2, and it is not necessary to stick to the limited space of the body 20. Therefore, the present invention can simplify the processing and assembly process of the inductor and the difficulty; it is not necessary to stick to the body 2〇, and the winding of the coil 30 is delayed; and the assembly process is not complicated or the assembly space is limited. When the coil 30 and the body 20 are assembled, it is only necessary to directly mount the previously wound coil 30 from the open face 23 of the body 20 in the groove 21, and to make the through hole 31 of the coil 3〇. The inductors of the present invention are formed by being aligned with the protrusions 22 of the body 2〇 and positioning the two ends 32 and 33 of the coils on the two electrodes 25 and 26, respectively. It is extremely easy to assemble, achieves a simple manufacturing process, and significantly reduces the effectiveness of product defect rates. Moreover, the assembled inductor of the present invention naturally forms a closed surface 24 on the 20-face of the body, which can improve the support of the inductor _ ^ degree, and can reduce the electromagnetic interference, without having to additionally set the metal. In the case of a new inductor, the two electrodes 25, 26 are soldered to the circuit of the circuit 7 M3 04761, so that when the current passes through the coil 3, an inductive effect can be produced. Since the two electrodes 25 and 26 are soldered on the surface of the circuit board, the four sides of the open surface 23 of the main body 2 and the protrusions 22 can abut against the circuit board, and the strength can be increased by the board and the support. The circuit board can also enclose the electromagnetics of the coils and reduce electromagnetic interference. 'A Please refer to Fig. 6, which shows another embodiment of the present invention. This embodiment reveals that a shielded magnetic field is attached to the recess 21 of the open face 23 of the body 20 to enclose the electromagnetic field of the coil 30 to avoid electromagnetic interference. The masking sheet 27 can be a core sheet or other sheeting article having a shielding effect. Referring to Figure 7, a further embodiment of the present invention is illustrated. The actual example is not disclosed, the open faces 23 of the two bodies 20 of the two inductors can be connected together, and the pins 4 引 are respectively led out from the two electrodes 25 and 26 for soldering with the circuit board; (4) The inductor of the embodiment of Fig. 7 has the same resistance to current and reduced line impedance. In addition, as shown in FIG. 8, when the two inductors are connected together by the open faces of the bodies 20, the coils 3 of the two inductors can be connected in series to form a set of coils 3 0; The inductor gate of the embodiment of Fig. 8 has the effect of increasing the inductance value. In this way, the two bodies 2 形成 form a closed shape due to the docking of the open faces 23, thereby closing the electromagnetic force of the coil 3〇 to avoid electromagnetic interference; and having the resistance of the two coils 3〇, and the L lowering line The effect of the impedance or increasing the inductance value; and the strength of the body 20 can be enhanced by the combination of the two bodies 20. Although the present invention has been described in detail by the above-described preferred embodiments, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the present invention to M304761, that is, the application according to the present invention.
