Description of the Related Art Conventionally, a coil component in which a winding wound with a rectangular wire is attached to an annular core is known. This coil component is formed, for example, by winding a rectangular wire around a core that is integrally formed in an annular shape (see, for example, Patent Document 1).

特開２０００−１００６４３号公報JP 2000-1000064 A

しかしながら、円環状のコアに平角線を巻き付ける場合には、巻線の端部をコアの内径よりも長く引き出した状態で巻き付けることができないので、巻線の端部に、引出端子を中継しなければならなかった。そのため、接触抵抗が大きくなり、特性が低下してしまうという問題があった。   However, when winding a rectangular wire around an annular core, it is not possible to wind it with the end of the winding extended beyond the inner diameter of the core, so the lead terminal must be relayed to the end of the winding. I had to. For this reason, there is a problem in that the contact resistance increases and the characteristics deteriorate.

本発明は、このような問題に基づきなされたものであり、特性を向上させることができるコイル部品及びその製造方法を提供することを目的とする。   The present invention has been made based on such a problem, and an object thereof is to provide a coil component capable of improving characteristics and a method for manufacturing the same.

本発明のコイル部品は、平角線を巻回した巻線を円環状の継ぎ目のない一体物よりなるコアに装着したものであって、巻線の一端部には第１引出端子が連続して一体的に形成されると共に、巻線の他端部には第２引出端子が連続して一体的に形成され、第１引出端子及び第２引出端子は、先端が、コアからコアの内径よりも離れた領域まで引き出されているものである。   The coil component of the present invention is obtained by mounting a winding wound with a rectangular wire on a core made of an annular seamless unit, and a first lead terminal is continuously provided at one end of the winding. In addition to being integrally formed, a second lead terminal is continuously formed integrally with the other end of the winding, and the first lead terminal and the second lead terminal have tips from the core to the inner diameter of the core. Is also drawn to a distant area.

本発明のコイル部品の製造方法は、円環状の継ぎ目のない一体物よりなるコアに、平角線を巻回した巻線を装着したコイル部品を製造するものであって、コアに平角線を一方の端部から巻いたのち、巻いていない残りの一部をコアに巻きながら、巻いた一方の端部を伸ばすことにより、巻線と、巻線の一端部に第１引出端子を連続して一体的に形成すると共に、平角線の他方の端部を巻かずに残すことにより、巻線の他端部に第２引出端子を連続して一体的に形成するものである。   The method of manufacturing a coil component according to the present invention is a method of manufacturing a coil component in which a winding made by winding a flat wire is mounted on a core made of an annular seamless integral piece. After winding from the end of the wire, while winding the remaining unwrapped portion around the core, extending one end of the wound, the winding and the first lead terminal to one end of the winding continuously The second lead terminal is continuously formed integrally with the other end portion of the winding by integrally forming and leaving the other end portion of the rectangular wire without being wound.

本発明のコイル部品によれば、巻線に連続して一体的に形成した第１引出端子及び第２引出端子の先端を、コアからコアの内径よりも離れた領域まで引き出すようにしたので、第１引出端子及び第２引出端子を中継接続する必要がなく、接触抵抗を小さくすることができる。よって、特性を向上させることができる。   According to the coil component of the present invention, the leading ends of the first lead terminal and the second lead terminal that are integrally formed continuously with the winding are drawn from the core to a region that is farther from the inner diameter of the core. There is no need to relay-connect the first lead terminal and the second lead terminal, and the contact resistance can be reduced. Therefore, characteristics can be improved.

また、本発明のコイル部品の製造方法によれば、コアに平角線を一方の端部から巻いたのち、巻いていない残りの一部をコアに巻きながら、巻いた一方の端部を伸ばすことにより、巻線と、巻線の一端部に第１引出端子とを連続して一体的に形成するようにしたので、本発明のコイル部品を容易に製造することができる。   Further, according to the method for manufacturing a coil component of the present invention, after winding a rectangular wire around one end of the core, the other end that is wound is stretched while winding the remaining unwrapped portion around the core. Thus, since the winding and the first lead terminal are continuously and integrally formed at one end of the winding, the coil component of the present invention can be easily manufactured.

以下、本発明の実施の形態について図面を参照して詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１は、本発明の一実施の形態に係るコイル部品１０の構成を表すものであり、図２は、図１に示したＩ−Ｉ線に沿った断面構造を表すものである。このコイル部品１０は、例えば、コア１１と、ボビン１２と、巻線１３とを備えている。   FIG. 1 shows a configuration of a coil component 10 according to an embodiment of the present invention, and FIG. 2 shows a cross-sectional structure along the line II shown in FIG. The coil component 10 includes, for example, a core 11, a bobbin 12, and a winding 13.

コア１１は、円環状の継ぎ目のない一体物よりなり、例えば、フェライト等の磁性体材料により構成されている。コア１１の断面形状は、例えば、多角形でも、円形でも、楕円形でもよい。ボビン１２は、コア１１と巻線１３との絶縁性を高めるためのものであり、例えば、中空の円環状とされており、中空部にコア１１を収納し、コア１１を覆うように配設されている。ボビン１２は、例えば合成樹脂により構成されている。なお、ボビン１２は、備えていなくてもよい。また、ボビン１２に代えて絶縁紙をコア１１に巻いてもよい。   The core 11 is made of an annular seamless unit, and is made of, for example, a magnetic material such as ferrite. The cross-sectional shape of the core 11 may be, for example, a polygon, a circle, or an ellipse. The bobbin 12 is for improving the insulation between the core 11 and the winding 13, and is, for example, a hollow annular shape. The core 11 is accommodated in the hollow portion and disposed so as to cover the core 11. Has been. The bobbin 12 is made of, for example, a synthetic resin. The bobbin 12 may not be provided. Further, instead of the bobbin 12, insulating paper may be wound around the core 11.

巻線１３は、例えば、銅やアルミニウム等よりなる導線を絶縁被膜により被覆した平角線をエッジワイズに螺旋状に巻回することにより構成されている。巻線１３は、コア１１に対して１個配設するようにしてもよく、また、複数個配設するようにしてもよい。なお、図１では３個配設した場合を示している。巻線１３の一端部には第１引出端子１４が連続して一体的に形成され、巻線１３の他端部には第２引出端子１５が連続して一体的に形成されている。第１引出端子１４及び第２引出端子１５は、先端が、コア１１から、コア１１の内径Ｌ１よりも離れた領域までそれぞれ引き出されている。なお、図２では、第１引出端子１４の先端がコア１１の内径Ｌ１よりもコア１１から離れた領域まで引き出されている状態を分かりやすく示すために、コア１１の断面部分と、第１引出端子１４と、第１引出端子１４と巻線１３との連続部分とを取り出して表している。   The winding 13 is configured by, for example, spirally winding a rectangular wire in which a conductive wire made of copper, aluminum, or the like is covered with an insulating coating in an edgewise manner. One winding 13 may be disposed with respect to the core 11, or a plurality of windings 13 may be disposed. FIG. 1 shows a case where three are arranged. A first lead terminal 14 is continuously and integrally formed at one end of the winding 13, and a second lead terminal 15 is continuously and integrally formed at the other end of the winding 13. The leading ends of the first lead terminal 14 and the second lead terminal 15 are drawn from the core 11 to a region separated from the inner diameter L <b> 1 of the core 11. In FIG. 2, in order to show the state in which the tip of the first lead terminal 14 is drawn to a region farther from the core 11 than the inner diameter L <b> 1 of the core 11, The terminal 14, the continuous portion of the first lead terminal 14 and the winding 13 are taken out and shown.

このように、このコイル部品１０では、第１引出端子１４及び第２引出端子１５を巻線１３と連続して一体的に形成し、かつ、コア１１からコア１１の内径Ｌ１よりも離れた領域まで引き出すことにより、第１引出端子１４及び第２引出端子１５を中継接続する必要をなくし、接触抵抗を低減することができるようになっている。第１引出端子１４及び第２引出端子１５を引き出す方向は任意であり、図１及び図２に示したのは一例である。   As described above, in this coil component 10, the first lead terminal 14 and the second lead terminal 15 are formed continuously and integrally with the winding 13, and the region is separated from the core 11 than the inner diameter L <b> 1 of the core 11. As a result, it is not necessary to relay-connect the first lead terminal 14 and the second lead terminal 15 and the contact resistance can be reduced. The direction in which the first lead terminal 14 and the second lead terminal 15 are pulled out is arbitrary, and the examples shown in FIGS. 1 and 2 are examples.

このコイル部品１０は、例えば、次のようにして製造することができる。図３から図５は各製造工程を表すものである。このコイル部品１０は、円環状の継ぎ目のない一体物よりなるコア１１に、平角線を巻回することにより製造する。   This coil component 10 can be manufactured as follows, for example. 3 to 5 show each manufacturing process. The coil component 10 is manufactured by winding a rectangular wire around a core 11 made of an annular seamless joint.

まず、例えば図３（Ａ）に示したように、コア１１にボビン１２を介して平角線を一方の端部から螺旋状に巻く。平角線を所定量巻いた後、例えば図３（Ｂ）に示したように、コア１１に巻いた平角線の一方の端部を直線状に伸ばしながら、巻いていない残りの一部をコア１１に巻く。次いで、例えば図４に示したように、平角線の一方の端部をコア１１からコア１１の内径Ｌ１よりも離れた領域まで引き出す。これにより、巻線１３と、巻線１３の一端部に第１引出端子１４とが連続して一体的に形成される。   First, for example, as shown in FIG. 3A, a rectangular wire is spirally wound around the core 11 via a bobbin 12 from one end. After winding the rectangular wire by a predetermined amount, for example, as shown in FIG. 3B, one end of the rectangular wire wound around the core 11 is linearly extended, and the remaining part that is not wound is core 11. Wrap around. Next, for example, as shown in FIG. 4, one end portion of the flat wire is pulled out from the core 11 to a region separated from the inner diameter L <b> 1 of the core 11. As a result, the winding 13 and the first lead terminal 14 are continuously and integrally formed at one end of the winding 13.

また、例えば図５に示したように、平角線の他方の端部は、巻かずにそのまま残すことにより、巻線１３の他端部に第２引出端子１５を連続して一体的に形成する。その際、第２引出端子１５の先端がコア１１からコア１１の内径Ｌ１よりも離れた領域まで引き出されるように、平角線の他方の端部を残す。   For example, as shown in FIG. 5, the other end of the flat wire is left as it is without being wound, so that the second lead terminal 15 is continuously formed integrally with the other end of the winding 13. . At that time, the other end of the rectangular wire is left so that the tip of the second lead-out terminal 15 is pulled out from the core 11 to a region away from the inner diameter L1 of the core 11.

このように本実施の形態によれば、巻線１３に連続して一体的に形成した第１引出端子１４及び第２引出端子１５の先端を、コア１１からコア１１の内径よりも離れた領域まで引き出すようにしたので、第１引出端子１４及び第２引出端子１５を中継接続する必要がなく、接触抵抗を小さくすることができる。よって、特性を向上させることができる。   As described above, according to the present embodiment, the tips of the first lead terminal 14 and the second lead terminal 15 that are formed continuously and integrally with the winding 13 are separated from the inner diameter of the core 11 from the core 11. Therefore, it is not necessary to relay-connect the first lead terminal 14 and the second lead terminal 15 and the contact resistance can be reduced. Therefore, characteristics can be improved.

また、コア１１に平角線を一方の端部から巻いたのち、巻いていない残りの一部をコア１１に巻きながら、巻いた一方の端部を伸ばすことにより、巻線１３と、巻線１３の一端部に第１引出端子１４とを連続して一体的に形成するようにしたので、第１引出端子１４の長さを自由に長くすることができ、本実施の形態に係るコイル部品１０を容易に製造することができる。   Further, after winding a rectangular wire around the core 11 from one end portion, the other end portion that is not wound is wound around the core 11 and the one end portion that is wound is stretched, thereby winding 13 and winding 13. Since the first lead terminal 14 is continuously and integrally formed at one end of the first lead terminal 14, the length of the first lead terminal 14 can be freely increased, and the coil component 10 according to the present embodiment. Can be easily manufactured.

以上、実施の形態を挙げて本発明を説明したが、本発明は上記実施の形態に限定されるものではなく、種々変形可能である。例えば、コア１１は、例えば、薄帯コアを環状に巻くことにより、円環状に形成したものでもよい。   The present invention has been described with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, the core 11 may be formed in an annular shape by, for example, winding a thin ribbon core in an annular shape.

また、上記実施の形態では、コア１１と、ボビン１２と、巻線１３とを備える場合について、各構成要素についても具体的に説明したが、全ての構成要素を備えていなくてもよく、また、他の構成要素を備えていてもよい。   In the above embodiment, each of the constituent elements is specifically described for the case where the core 11, the bobbin 12, and the winding 13 are provided. However, not all the constituent elements may be provided. Other components may be provided.
