If this is expressed as an experimental result, it is as shown in FIG. 5. Fig. 5 (a) is a graph showing a direct current-inductance characteristic curve of an experimental example of a surface-mounted current-resistant coil using a core formed by a toroidal core and a cylindrical core. Figure 5 (b) is a graph showing a DC current-inductance characteristic curve of a conventional test case of a PR-type core with a combination of a pot-type core and a rivet-type core on the surface of a PR-type core. The external dimensions of any of the current-resistant coils are composed of 12.5 mm in height and width, and 5 · 5 mm in height. Rated inductance: 10 volts. Product: The measurement is performed at room temperature of 25 ° C. The conventional example in FIG. 5 (a) is that the superimposed DC current slightly exceeds 4 · 〇 4A. The characteristics will decrease sharply: but the embodiment shown in Fig. 5 (b) is an superimposed DC current to 7. A can be used for products of 10 to Η. If the experimental example of the conventional example and the experimental example of the example are compared, the DC current overlap characteristic is improved by about 3.0 A, and: in terms of the number of assembly operations of the surface-mounted anti-current line, although the present invention seems to Compared with the previous 6 process to 5 process, but when in-depth review of the work content of each process, each work content of the present invention is Thai paper size applicable to Chinese National Standard (CNS) A4 specification (210 X 297 mm)- ----------- — -Installing --- < Please read the note on the back page of Dongxiang Factory first) Order-line. Printed by A7 B7 434593, Consumer Cooperatives, Bureau of Intellectual Property, Ministry of Economic Affairs V. Description of the invention (9) How to simplify and shorten the assembly operation: it is easy to understand. In addition, as the electric wires constituting the coil 3, the use of a flat-angle electric wire having a rectangular cross-section of a rectangular rectangular copper wire formed by cutting an extremely thin electrical copper plate and applying a film of an insulating material can reduce the number of surface-mounted anti-current coils. Internal resistance. That is to say, the flat-angle electric wire commercially available generally has an oblong cross-sectional shape. In contrast, the flat-angle electric wire formed by the above process has a rectangular cross-sectional shape, and the cross-sectional shape is a rectangular flat angle. The ratio of the cross-sectional area of the flat-angle wire itself when the wire forms the coil can be almost 100%. This is not only to reduce the internal resistance of the surface-mounted current-resistant coil, but also to help increase the surface area. The rated current of the current-carrying coil is installed; and, when a commercially-available flat-angle wire is used to form a flat-angle wire coil, those who construct a flat-angle wire coil according to the present invention can reduce the manufacturing cost of the flat-angle wire coil by about 3: This will help reduce the overall manufacturing cost of the surface mounted anti-current coil: And, it is not necessary to form a through hole 10 2 on the top wall 10 of the pot-shaped iron core 10, and only open the peripheral edge of the lower end, By sealing the flat-angle wire coil 3 tightly «in the space formed by the pot-shaped iron core 10 and the rivet-shaped iron core 20, there will be almost no leakage of magnetic flux. [Effect of the invention] As mentioned above, The surface-mounted current-resistant coil core can improve the DC current overlap characteristics of the surface-mounted current-resistant coil by combining the pot-shaped iron core 10 and the rivet-type iron core 20 with the p R-shaped iron core. "PR-type iron core" can simplify the assembler. Please read the note on the back. I.
