In detail, this creation provides an inductor that can replace the magnetic core to make the inductive component have different inductance characteristics. element. [Prior Art] Inductive components have functions such as filtering, suppressing transient current, reducing EMI noise and power conversion, and have been widely used in various electronic products for a long time, and are indispensable components in electronic products. Furthermore, the inductive component is a passive component in an electronic circuit and can be classified into different types according to its application environment, product structure, shape, and use. In general, *inductive components are mostly in the form of coil windings. The coil thickness can be used to control the withstand current, and the number of coil turns can be adjusted to adjust the inductance value. On the other hand, the product characteristics of the inductor component are mainly affected by the core material. For example, ceramic cores are commonly used for signals, while ferrite cores are used to suppress EMI. Therefore, the design of the inductor component covers the electromagnetic theory, magnetic materials and the knowledge of many aspects of the Anji Temple. Designers need to design the coil of the inductor according to the working conditions and related requirements, such as current, voltage, frequency, temperature and material properties. Number and size, core shape and material. For example, an integrally formed inductor component is fabricated by using a conventional component molding apparatus by first placing a raw material powder and a coil into a cavity of the component molding apparatus, and then using the upper and lower punches to press and form. The inductor element shown in FIG. 1 is a schematic view of an integrally formed inductor element. The inductor element 1 includes a coil 12 and a cover M383190 11 which is formed by pressing the raw material powder. The coil 12 is wound by a spiral conductor. The coil body 120 and the front and rear wiring portions 121 and 122 extend from the front and rear end portions of the coil main body 120, and the coil main body 120 has a hollow portion (not shown), and the cover body 11 is exposed to the outer portion of the coil 12. The coil 12 is covered by the front and rear wiring portions 121 and 122, and it is to be noted that the hollow portion of the coil main body 120 is filled with the raw material powder forming the cover 11. Therefore, in the integrally formed inductor element 1, the substance in the hollow portion of the coil main body 120 is the same material as the cover body 11, in other words, the magnetic core surrounded by the coil 12 and the outer cover of the cover coil 12 are identical in material. . However, when it is necessary to adjust the material in the hollow portion of the coil main body 120 and the material of the cover 11 in order to produce an inductance having different characteristics, it is necessary to increase the manufacturing procedure or cost. Therefore, how to provide an inductive component can retain the advantage of a small volume of the integrally formed inductor component, and at the same time has the flexibility of replacing the core surrounded by the coil, which has become an urgent problem to be solved. [New content] In view of the above disadvantages of the prior art, the purpose of the present invention is to provide an inductor element with a replaceable magnetic core, which can be formed by replacing magnetic cores of different materials or shapes to form inductance elements having different inductance characteristics. Increase the variability of the inductive components and reduce the cost of making various inductive components.

The cover of the inductive component of the replaceable magnetic core created by the powder can be (4) different materials, &' and the material constituting the core and the material constituting the cover are replaceable by the prior art The inductor and the cover of the core are not integrally formed, but the cover that is covered with the coil is first made _ "the core is combined, so the variability and flexibility of the finished product can be increased" while 70 manufacturers are based on the inductance characteristics. f When manufacturing a customized inductive component, the manufacturing cost thereof is also reduced. [Embodiment] M383190 Hereinafter, embodiments of the present invention will be described by way of specific embodiments, and those skilled in the art can be disclosed by the present specification. The contents can easily understand other advantages and effects of the present invention, and can be implemented or applied by other different embodiments. Please also refer to Figures 2A and 2B, and Figure 2A shows the replaceable magnetic core of the present invention.

The coil body 220 is formed in a spiral shape and has a hollow portion 213. The hollow portion 213 may be circular or elliptical. The spiral wrapping technique is a conventional technique for manufacturing an inductive component, and thus will not be described herein. The coil 22 is covered with a portion of the front terminal portion 221 and the rear terminal portion 222, and as shown in FIG. 1A, the cover body 21 forms a through hole 210 through the hollow portion 213 of the coil body 220. In an embodiment, The cover 21 can be press-formed by the component molding apparatus using the raw material powder. The magnetic core 20 is passed through the hole 210 of the cover 21 to form the inductive component of the present invention. The magnetic core 20 is detachable. In addition, the inductive component 2 of the replaceable magnetic core of the present invention includes an adhesive (not shown) applied to the magnetic core and/or the hole of the cover to penetrate the magnetic core 20 into the cover 21 . When the hole 210 is formed, the core 20 is bonded to the cover 21. Generally speaking, The coil 22 is made of a conductive material, for example, a copper wire covered with an insulating paint of M383190. It is worth mentioning that the front wire portion 221 and the rear wire portion 222 can be formed by pressing the copper wire as shown in FIG. 2A. In a specific implementation, the cover 21 may be composed of a magnetic material or a non-magnetic material. If the cover 21 is a magnetic material, the inductor element 2 is a closed magnetic circuit mode, and if the cover 21 is a non-magnetic material, the inductor is made. The element 2 is an open magnetic circuit mode. In an embodiment, the non-magnetic material may be, for example, a plastic, a resin, or the like, and the magnetic material may be divided into a metal magnetic material and a ferrite, wherein the metal magnetic material is mainly iron, nickel, cobalt. Elements and their alloys, such as iron-silicon alloy, iron-alloyed alloy, iron-bonded gold, Pengshi alloy, pulverized alloy and fierce alloy, etc.; ferrite system refers to magnetic oxide containing iron oxide as the main component, also known as Magnetic porcelain. Secondly, the adhesive may be a thermosetting or quick-drying adhesive, the thermosetting adhesive may be, for example, an epoxy resin, and the fast drying adhesive may be, for example, a UV quick-drying adhesive. It should be noted that, in the present creation, the appearance of the magnetic core 20 or the cover 21 is not limited to the second and second views, and the front terminal portion 221 and the rear connection portion 222 of the coil 22 may also extend. It changes according to the actual circuit. It can be understood from the above embodiments that the inductor element of the magnetic core can be replaced by forming the cover body and the coil first, and then replacing different magnetic cores according to customer requirements to fabricate the customized inductance component. Further, the material constituting the magnetic core and the material constituting the cover are different materials. Furthermore, please refer to Fig. 3, which is a schematic view of another embodiment of the inductive component of the replaceable magnetic core. The inductance element 3 mainly includes a magnetic core 30, a cover 31, and a coil 32. 7 M383190 - ♦ The coil 32 is composed of a conductor having a coil main body 320, a front wiring portion 321, and a rear wiring portion 32, and the coil main body 320 is formed in a spiral shape and has a hollow portion. The magnetic core 30 is provided in the hollow portion of the coil main body 320. The cover 31 covers the coil 32 and the magnetic core 30, and exposes a part of the front wiring portion 321 and the rear wiring portion 322 of the coil 32. In a specific implementation, the inductive component as shown in FIG. 3 can be fabricated by the component molding apparatus, and the magnetic core 30, the coil 32, and the raw material powder to be formed into the outer cover 31 are placed in the cavity of the component molding apparatus according to a predetermined procedure. Then use the upper and lower punches to press and form. In the present embodiment, since the magnetic core 30 and the raw material powder to be formed into the cover 31 are respectively placed in the cavity, the magnetic core 30 and the outer cover 31 may be composed of different materials. Further, since the inductance element shown in Fig. 3 is integrally formed, it is not necessary to use the adhesive included in the inductance element shown in Fig. 2. In summary, in the embodiment in which the cover body is not covered with the magnetic core, the cover body covering only the coil can be fabricated first, and different magnetic cores are added according to customer requirements to become a customized inductor. When the cover body is coated with the magnetic component of the magnetic core, the coil, the magnetic core, and the powder raw material may be placed in the cavity of the component molding device in a predetermined order, and then pressed by the upper and lower punches. Therefore, the inductor element of the magnetic core can be replaced by the difference between the magnetic core surrounded by the coil and the cover body covering the coil, so that the inductance component with different inductance characteristics can be fabricated, and the variation of the finished inductor component can be increased. Sex and flexibility, and can retain the M383190 advantage of the small size of the integrated inductor component, which in turn reduces production costs. The above embodiments are merely illustrative of the principles and functions of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify and change the above embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation should be as listed in the patent application mentioned later.
