Fig. 7A is a perspective view showing a configuration example of the bobbin cover 16, and Fig. 7B is a perspective view of the bobbin cover 16 as seen from the bottom surface side. 125497.doc 200849291 The coil component 11 includes a coil bobbin 丨2, a core including a core portion 13 and a core portion 14, and a coil 15 wound by a twisted wire, which are respectively disposed at both ends of the winding core portion 12a of the coil bobbin 12. The bobbin cover 16 disposed between the terminal holding portions 12c extending from the crotch portion 12b is assembled and disposed on the coil bobbin 12 by the central magnetic leg 13a of the core portion 13 and the central magnetic leg i4a of the core portion 14 The core groove 12e is formed, and the coil component ^ is fabricated. The coil bobbin 12 is made of, for example, an insulating resin material, and for example, a thermosetting resin material can be used. Further, the method of forming the coil bobbin 12 can be performed by, for example, injection molding. As shown in FIG. 6A and FIG. 6B, the coil bobbin 12 has a crotch portion 12b at both ends of the cylindrical core portion 12a around which the twisted wire is wound, and a plurality of roots are provided on the terminal holding portion 12c extended to the crotch portion i2b. The terminal 12d is connected to each other. Further, it has a core groove 12e into which the center magnetic leg 13a of the core portion 13 and the central magnetic leg i4a of the core portion 14 are inserted. The connection terminal 12d is a fixing pin for fixing the coil component to, for example, a printed circuit board by soldering or the like. A plurality of connection terminals 12d are provided at the lower portion of the coil bobbin 丨2. Further, in the coil component cartridge of the present embodiment, the connection terminal 12d is used as a terminal. In other words, the connection terminal 12d is made of a conductive material such as metal, and the connection terminal 12d is electrically connected to the connection terminal 12d, for example. The core is composed of, for example, a core portion 13 and a core portion 14 which are formed by press-molding and sintering the ferrite-iron powder, and for example, a core portion (core portion 3 and core portion) having a cross-section E-shaped with three magnetic legs 14), relative to each other in such a way that the three magnetic legs match each other. In other words, the core portion 13 and the core portion 14 are formed in such a manner that the magnetic legs 13a, 13b, and Ue of the core portion 13 and the magnetic legs 14a, 14b, and 14c of the core portion 125497.doc 200849291 are respectively aligned. . The central magnetic leg 13a of the core portion 13 and the central magnetic leg 14a of the core portion 14 are inserted into the core groove 126 of the coil bobbin 12, respectively. The coil 15 is, for example, a coil wound around a copper wire or the like wound around the coil bobbin 12 by a twisted wire. In consideration of the insulating property, the protection of the coil 15, and the like, for example, a sheet member having an insulating property on the outer surface may be covered after winding the twisted wire. The bobbin cover 16 is formed by, for example, injection molding an insulating resin material, and is disposed between the terminal holding portions 12c of the coil bobbin 12 to prevent deformation of the impact-based coil bobbin ,2 and prevent engagement. The crack of the part 12f occurs and is broken. As shown in FIG. 7A and FIG. 7B, the bobbin cover μ is provided with a crotch portion 16b at both ends of the bottom surface portion 16a of the substantially rectangular shape that is in contact with the surface of the printed circuit board when mounted on the printed circuit board, respectively. A fitting rib 16c is extended on the crotch portion 16b.

By the crocodile part b6b, the bobbin cover 6 is disposed between the terminal holding portions 12c, and the ribs 16c are keyed and engaged with the coil bobbin 12, thereby suppressing the arrangement of the bobbin cover 16 to the connection terminal i 2d. mobile. 125497.doc 200849291 The spool cover 16 is preferably made of a high-grade (4) resin material, for example, by injection molding a resin material such as ABS (acrylonitrile-butadiene-styrene) resin or nylon resin. Further, even if it is a resin material such as a low-toughness thermosetting resin, the strength of the bobbin cover can be increased by providing a single or a plurality of reinforcing ribs 16d on the bobbin (four) of FIG. 4, FIG. 7 and FIG. Further, the thermosetting resin may, for example, be an epoxy resin, a melamine resin, a polycarbamic acid, a polyimine, etc. Further, by providing a hole 16e' in the crotch portion 16b of the bobbin cover, the injection may be performed. The flow of the resin material at the time of molding is to improve the formability and increase the strength of the bobbin cover 16. The hole W is not limited to the direction shown in Fig. 7A as long as the flow of the resin material can be made uniform during injection molding, and can be formed in any direction. For example, the boss portion i6b and the crotch portion 16b may be formed as a bobbin cover 16 that is fitted in the same direction 0 as the extending direction of the strength enhancing rib 16d to the coil bobbin 12, and is fixed to the coil bobbin 12. The fixing method includes a method of fixing the fitting holding portion 12c of the coil bobbin 12 and the fitting rib 丨6c of the bobbin cover 16 by ultrasonic welding or an adhesive, or by applying the adhesive tape 2 as shown in FIG. 〇 The bobbin cover 16 thus produced is inserted into the substrate 21 by inserting the connection terminal 12d into the substrate 21, and the connection terminal 12 (i and the substrate 21 are joined by soldering, and the connection terminal 12d and the substrate are bonded as shown in FIG. The conductive pattern portion of the 2 1 is electrically connected. As described above, since the bobbin cover 16 is disposed between the terminal holding portions 12c of the coil bobbin 12, the bobbin cover 16 can be the shaft fixing terminal holding portion 2c, It is possible to prevent the occurrence of cracks on the joint portion 12f of the coil bobbin 12 and the damage of the joint portion 2f of the winding portion of the coil bobbin 12 to obtain a coil component which is excellent in impact resistance. Further, since the coil 15 can be prevented from being broken The wire does not damage the electrical performance of the coil component u. Further, by providing the bobbin cover 16, the coil bobbin 12 is inserted into the substrate 21, and the bottom surface portion 16a is in surface contact with the substrate 2, so that the coil component can be inserted.
