Description of the Invention (1) Technical Field of the Invention The present invention relates to choke coils, and in particular, there is no risk of terminals being damaged or broken. The choke ring is simplified in structure and easy to assemble as a whole. Conventional Techniques A conventional example of a SMD (’Surface Mount Device) choke coil will be described with reference to FIGS. 4 and 5. Fig. 4 (a) is an oblique view of the S M D choke coil, and Fig. 4 (b) is a sectional view taken along line b-b 'of Fig. 4 (a). Fig. 5 is an exploded perspective view of the SMD choke coil of Fig. 4. In Figs. 4 and 5, 1 is a ring-shaped core, 2 is a cylindrical core, 3 is a coiled wire, and 4 is a terminal. These toroidal cores 1 and cylindrical cores 2 are made of fernte, which is an electrically insulating material. The ring-shaped core 1 is formed with a pair of flat portions 12 facing each other on a part of its side surface. The arcuate surface portions 13 adjacent to the pair of flat portions 12 facing each other form a notch 11 in the lower end portion thereof. The cylindrical core 2 is formed by a pair of crotch portions 21 and a core portion 22 which is integrated with the two crotch portions 21 to connect the two. Part of these two cymbals 21 is formed with a pair of flat portions 211 facing each other. A coil 3 is wound around the core portion 22 of the cylindrical core 2 to form a coil 30. The terminal 4 is formed with a cut-and-raised piece at a central portion thereof as a terminal core fixing portion 41. Moreover, at one end portion of this terminal 4, its front end is slightly bent on the same plane as the abdomen of the terminal body to be used as a welding pad. ιτ ------ ^ (Please read the notes on the back before filling this page) This paper size applies to the national standard of China (CNS) Α4 specification (210X297 mm) -4-412761 Α7 Β7 Central Bureau of Standards, Ministry of Economic Affairs Printed by the employee's consumer cooperative V. Description of the invention (2) 4 2 At the same time, the other end's end was bent at a right angle to be used as the rising part 4 3 0 Manufactured above the ring-shaped core 1 'Cylinder core 2, coil 3, Terminal 4. Here, referring to FIG. 5 (b), the terminal 4 is passed through the iron core fixing portion 41 and connected to and fixed to the surface of the cymbal portion 21 of one of the cylindrical iron cores 2 by a resin-based adhesive. In this case, the rising portion 43 of the terminal 4 faces the flat portions 2 1 1 of the two flange portions 21 of the cylindrical core 2 and is connected and fixed in parallel with each other. Next, referring to Fig. 5 (c), the winding wire 3 is wound around the core portion 22 of the cylindrical core 2 having the structure shown in Fig. 5 (b). Furthermore, the ends of the two coils of the coil 3 are wound around the solder portion 42. In a state in which the solder portion 42 of the terminal 4 is wound around the coil end of the coil 3, reflow soldering is performed on the wound solder portion 42 to electrically and mechanically connect the terminal 4 and the coil 3 to each other. The cylindrical core 2, the coil 3, the terminal 4, and the ring-shaped core 1 are fitted. When the ring-shaped iron core 1 is fitted, the notch 1 1 at the lower end of the arc surface portion 1 3 of the ring-shaped iron core 1 faces the wound solder portion 4 2, and the lower end of the flat portion 12 corresponds to the rising portion 4 3 of the terminal. Fit them parallel to each other. The wound solder portion 4 2 of the terminal 4 is bent after being soldered, and the notch 11 constitutes an area for accommodating this bent wound solder portion 4 2. Problems to be Solved by the Invention Here, 5 indicates the gap between the coil 30 and the toroidal core 1 formed by the cylindrical core 2 and the coil 3. The gap 5 is filled with heat-hardening adhesive, and then a filler is added and hardened to complete the assembly of the entire choke. However, the problem lies in that the terminal 4 passes through the terminal iron core fixing part 41. The Chinese national standard (CNS) M size (210X297 cm) is applied to the paper size of the ring (please read the precautions on the back before filling this page)- s 412761 A7 B7 Printed by the Consumer Sample Cooperative of the Sample Prospective Bureau in the Ministry of Economic Affairs 5. Description of the invention (3) An epoxy resin adhesive is connected and fixed to the surface of one of the cymbals 2 1 of the cylindrical core 2 and this connection is fixed Due to the addition of thermosetting adhesive and hardener, it will be damaged when it is added. In addition, the connection and fixing of the core fixing portion 41 of the terminal 4 on the surface of one of the crotch portions 21 of the cylindrical core 2 is accompanied by difficulties. That is, careful attention needs to be paid to the management and adjustment of the application amount of the adhesive, and the adjustment of the application amount of the adhesive requires a long time. In addition, when there is a difference in the application amount of the adhesive, a large difference occurs in the bonding strength of the product and the stability of the bonding time. In addition, the above choke ring has no centering structure. In the manufacturing process, no special centering project is taken, and the finished product is likely to be eccentric. In addition, during the manufacturing process, including the adhesive bonding process and the heat-hardening and adhesive hardening process, the total manufacturing time is longer. The present invention is to provide a choke ring which eliminates the above problems.

Description of the invention (6) The adhesive of the wire terminal 31 has cured the wire 圏 30 and the insulating pipe 6 made of insulating material. Referring to FIG. 3 (d), this shows the assembly of the coil and the insulating tube 6 made of insulating material in the circular hole 10 of the ring-shaped iron core 1. The pull-out end 3 of the coil 3 is passed through the temporary fixing groove 2 1 2. The groove 14 formed at the lower end of the ring-shaped iron core 1 is pulled out, and then the square-shaped terminal 4 ′ is elastically covered and fixed to the ring-shaped iron core 1 as described previously. Referring to Fig. 3 (e), this shows a winding solder portion 42 of the winding end 3 3 of the coiled wire 3 wrapped around and fixed to the 3-shaped terminal 4 'of the ring-shaped core 1. Referring to Fig. 3 (f), this shows that the pull-out end 33 of the coil 3 is soldered to the wound solder portion 42 to become the solder portion 45. Referring to FIG. 3 (g), this shows that the winding-soldering portion 42 after the pull-out end 33 is soldered is bent so as to be close to the ring-shaped core 1, so that the outer dimension of the choke ring becomes small.
