Its function is to bypass the noise in the current and stabilize the current in the circuit to prevent electromagnetic interference. To store and release the electrical energy in the circuit to adjust the stability of the current, except that the capacitor is an electric field (electrical form to store electrical energy, and the inductance is in the form of a magnetic field. However, the electric and magnetic can mutually Conversion, a magnetic field is generated around the wire through which the current flows; on the contrary, a current is generated in the coil that cuts the magnetic field line. The structure of the inductor is to wind the wire around the coil, which is somewhat like a full-length sewing line, when current flows It will be filled with magnetic energy. When the current is small, the coil will generate a force to prevent current changes. It can be used in a wide range of applications, including power supplies, monitors, switches, motherboards, scanners, telephones, modems, etc. With the rapid development of the electronics industry, the requirements for the precision of the dragon sensor are relatively higher, and the demand for the loss is 1 low and the product is small and Low production cost and production in a fully automated manner, which is the trend of the current electronics industry, while the traditional inductor is wound by a ring-shaped magnetic conductor (as shown in the figure). Guardian production, contact efficiency and cost and loss are all major problems. ..., the patent number applied by Shen Mingren · · 2〇〇42〇〇43695· 3 and patent number: 5 M344559 200420074369.9 inductance The device is made of E/I type magnetic conductor with the density of casting pressure, and the winding coil is arranged in the E-type magnetic conductor, and then the 鳞-shaped scale body is covered, and the squash type is combined by the manufacturing method. After the conductor is cast, the density is more compact, so that the E/Ι type magnetic conductor is tightly combined, and after the winding is completed, the ends m, m are formed, and before the E-shaped magnetic conductor is placed. Firstly, it is pressed into a flat shape and then placed into the magnetic body. After the casting is completed, the flat ends ln and m are bent, and the efficiency is small, the cost is reduced, and the production is easy. (As shown in Figure 2). 'Inductors can also be divided into plug-in type and SM D type (as shown in Figures 1-2, 1-3, 1-4), wherein the #SMD type inductor manufacturing step (as shown in Figure 6-1) includes: a winding step (8) providing a coil η Winding-fixing ugly, forming-winding; pressing step (a2), providing Xuan two-end box, (1), pressing by the tool to form a riding shape, if the system is smaller, at the end 112, 112, the sleeve The copper sleeves 13 and 13 are further stamped and pressed to form a word; the accommodating step (10) is provided to provide the impurity suppression to be placed in the E-type magnetic conductor 1 ;; and the sealing step (a4) is provided to provide the j-type magnetic conductor 12 In the step of f-folding (10), the extended magnetic conductor 10 and the outer flat-shaped coil η end portions 112, 112' are bent to form an SMD-type inductor structure ι; The disadvantage of the type inductor is small, and the production process is complicated, and it needs to be processed manually; 2. The E/Ι type magnetic conductor is produced separately in the early days, which increases the cost and time-consuming, and the error between the two castings is high, resulting in poor inductance.
