Abstract

PROBLEM TO BE SOLVED: To provide a coil bobbin in which wires of respective layers can be arranged with no clearance gap in superimposed state, and to provide a coil component using such a coil bobbin.SOLUTION: In a coil bobbin 2, a step D comparable to the diameter of a wire 3 is provided between a first edge 14 facing a cutout part 13 and a second edge 15 on an inside surface 12b of a flange 12. When the wire 3 introduced from the cutout part 13 is wound along the inside surface 12b of the flange 12, a bent portion 3a of the wire 3 can be offset by the diameter of the wire 3 to the outside surface 12a side of the flange 12 by means of the step D. Since deformation of the wire 3 which is wound in second lap or thereafter and follows up the shape of the bent portion 3a of the wire 3 can be relaxed in the coil bobbin 2, occurrence of a clearance gap between the wires 3 and 3 can be minimized and the wires 3 and 3 of respective layers can be arranged with no clearance gap in superimposed state.

Description

本発明は、コイルボビン及びコイル部品に関する。   The present invention relates to a coil bobbin and a coil component.

従来、コイルボビンの巻芯にワイヤを多層に巻き付けてなるコイル部品がある。このようなコイル部品では、巻き付けるワイヤの長さのばらつきを抑えるため、各層のワイヤ同士が重なるように隙間なく整列した状態でワイヤを巻き付けることが理想的である。ワイヤの巻き付け手法に関する技術として、例えば特許文献１に記載の線材フォーミング方法がある。   Conventionally, there is a coil component in which wires are wound around a core of a coil bobbin in multiple layers. In such a coil component, in order to suppress variation in the length of the wire to be wound, it is ideal that the wire is wound in a state where the wires in each layer are aligned with no gap so as to overlap each other. As a technique related to a wire winding method, for example, there is a wire forming method described in Patent Document 1.

この線材フォーミング方法では、ノズルから繰り出されるワイヤの先端を屈曲させておき、ワイヤの先端部分をコイルボビンの鍔部の開口部に通した状態で、線材の直線部分を鍔部の内面に沿わせながらワイヤの巻き付けを行っている。   In this wire forming method, the tip of the wire fed out from the nozzle is bent, and the wire tip is passed through the opening of the flange portion of the coil bobbin, and the straight portion of the wire is aligned with the inner surface of the flange portion. The wire is wound.

しかしながら、上述した従来の方法では、鍔部の縁に沿うワイヤの屈曲部分が巻芯に対するワイヤの巻き始め部分となっている。このため、２周目以降に巻き付けられるワイヤがワイヤの屈曲部分の形状に追従して変形してしまうという問題があった。ワイヤの変形は、ワイヤの巻き付けの進行と共に強調されて伝播することがあり、ワイヤ間に隙間が生じる要因となる。ワイヤ間に隙間が生じると、各層のワイヤ同士の位置がずれてしまい、ワイヤ同士を重ねた状態で隙間なく整列させることが困難となる。   However, in the conventional method described above, the bent portion of the wire along the edge of the collar portion is the winding start portion of the wire around the winding core. For this reason, there is a problem that the wire wound after the second round is deformed following the shape of the bent portion of the wire. The deformation of the wire may be emphasized and propagated as the winding of the wire progresses, causing a gap between the wires. When a gap is generated between the wires, the positions of the wires in each layer are shifted, and it is difficult to align the wires without any gap in a state where the wires are overlapped.

本発明は、上記課題の解決のためになされたものであり、各層のワイヤ同士を重ねた状態で隙間なく整列させることが可能なコイルボビン、及びこのようなコイルボビンを用いたコイル部品を提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides a coil bobbin that can be aligned without gaps in a state in which the wires of each layer are overlapped, and a coil component using such a coil bobbin. With the goal.

上記課題の解決のため、本発明に係るコイルボビンは、ワイヤが巻き付けられる巻芯と、巻芯の両端にそれぞれ設けられる一対の鍔部とを備えたコイルボビンであって、鍔部には、ワイヤの引き出し口となる切欠部が径方向に形成され、鍔部の内側面は、巻芯の軸方向に直交する基準面からの距離が周方向で一定の増分で変化し、内側面において切欠部を臨む一方の縁部と他方の縁部との間にワイヤの直径と同等の段差が設けられていることを特徴としている。   In order to solve the above problems, a coil bobbin according to the present invention is a coil bobbin provided with a winding core around which a wire is wound and a pair of flanges provided at both ends of the winding core. A notch portion serving as a lead-out opening is formed in the radial direction, and the inner side surface of the collar portion changes in a constant increment in the circumferential direction from the reference plane perpendicular to the axial direction of the core, and the notch portion is formed on the inner side surface. A step equivalent to the diameter of the wire is provided between the one edge facing the other and the other edge.

このコイルボビンでは、鍔部の内側面において、切欠部を臨む一方の縁部と他方の縁部との間にワイヤの直径と同等の段差が設けられている。このため、切欠部から導入したワイヤを鍔部の内側面に沿って巻き付ける際に、ワイヤの屈曲部分を段差によってワイヤの直径分だけオフセットさせることができる。したがって、このコイルボビンでは、２周目以降に巻き付けられるワイヤが、ワイヤの屈曲形状に追従して変形することを緩和でき、ワイヤ間に隙間が生じることを抑制できるので、各層のワイヤ同士を重ねた状態で隙間なく整列させることが可能となる。   In this coil bobbin, a step equivalent to the diameter of the wire is provided between one edge part facing the notch part and the other edge part on the inner surface of the collar part. For this reason, when winding the wire introduced from the notch portion along the inner side surface of the flange portion, the bent portion of the wire can be offset by the diameter of the wire by the step. Therefore, in this coil bobbin, it is possible to alleviate the deformation of the wire wound after the second round following the bending shape of the wire, and to suppress the formation of a gap between the wires. It is possible to align without gaps in the state.

また、一方の鍔部に形成された切欠部と他方の鍔部に形成された切欠部とは、巻芯の軸方向から見た場合に互いに重ならない位置に形成されていることが好ましい。こうすると、一方の鍔部の切欠部からワイヤを導入し、他方の鍔部の切欠部からワイヤを巻き付ける際の整列ガイドを導入する場合に、整列ガイドからの押圧力によって一方の鍔部が変形することを防止できる。   Moreover, it is preferable that the notch part formed in one collar part and the notch part formed in the other collar part are formed in the position which does not mutually overlap when it sees from the axial direction of a core. In this way, when the wire is introduced from the notch of one collar and the alignment guide for winding the wire from the notch of the other collar is introduced, one collar is deformed by the pressing force from the alignment guide. Can be prevented.

一方の鍔部の内側面と他方の鍔部の内側面との間の距離は、ワイヤの直径の整数倍となっていることが好ましい。この場合、両鍔部の内側面にワイヤを密着して沿わせることができる。したがって、より好適にワイヤを整列させることが可能となる。   It is preferable that the distance between the inner side surface of one collar part and the inner surface of the other collar part is an integral multiple of the diameter of a wire. In this case, the wire can be closely attached to the inner side surfaces of the both flanges. Therefore, it is possible to align the wires more suitably.

また、本発明に係るコイル部品は、上記のワイヤボビンの巻芯にワイヤを多層に巻き付けてなるコイル部品であって、ワイヤは、鍔部の内側面が巻芯の中央に近づいていく方向に巻き付けられていることを特徴としている。   The coil component according to the present invention is a coil component in which a wire is wound around the winding core of the wire bobbin in multiple layers, and the wire is wound in a direction in which the inner surface of the collar portion approaches the center of the winding core. It is characterized by being.

このコイル部品では、鍔部の内側面において、切欠部を臨む一方の縁部と他方の縁部との間にワイヤの直径と同等の段差が設けられている。このため、切欠部から導入したワイヤを鍔部の内側面に沿って巻き付ける際に、ワイヤの屈曲部分を段差によってワイヤの直径分だけオフセットさせることができる。したがって、このコイル部品では、２周目以降に巻き付けられるワイヤが、ワイヤの屈曲形状に追従して変形することを緩和でき、ワイヤ間に隙間が生じることを抑制できるので、各層のワイヤ同士を重ねた状態で隙間なく整列させることが可能となる。   In this coil component, a step equivalent to the diameter of the wire is provided between one edge facing the notch and the other edge on the inner surface of the flange. For this reason, when winding the wire introduced from the notch portion along the inner side surface of the flange portion, the bent portion of the wire can be offset by the diameter of the wire by the step. Therefore, in this coil component, it is possible to alleviate the deformation of the wire wound around the second and subsequent turns following the bending shape of the wire and to suppress the formation of a gap between the wires. It is possible to align without any gaps in the state.

本発明によれば、各層のワイヤ同士を重ねた状態で隙間なく整列させることができる。   According to the present invention, the wires of each layer can be aligned with no gap in a state where the wires are overlapped.

以下、図面を参照しながら、本発明に係るコイルボビン及びコイル部品の好適な実施形態について詳細に説明する。   Hereinafter, preferred embodiments of a coil bobbin and a coil component according to the present invention will be described in detail with reference to the drawings.

図１は、本発明に係るコイル部品の一実施形態を示す斜視図である。また、図２は、図１におけるＩＩ−ＩＩ線断面図である。図１に示すように、コイル部品１は、例えば電源用のトランスやリアクトル等に使用される部品であり、コイルボビン２にワイヤ３を多層に巻き付けることによって構成されている。   FIG. 1 is a perspective view showing an embodiment of a coil component according to the present invention. 2 is a cross-sectional view taken along line II-II in FIG. As shown in FIG. 1, the coil component 1 is a component used for, for example, a power transformer or a reactor, and is configured by winding wires 3 around a coil bobbin 2 in multiple layers.

ワイヤ３は、例えば直径１ｍｍ程度の線状部材である。ワイヤ３は、各層のワイヤ３，３同士が同じ位置で重なるように隙間なく整列した状態で、コイルボビン２に巻き付けられている。また、ワイヤ３の端部は、コイルボビン２の鍔部１２に形成された切欠部１３（後述）を通して外部に引き出されている。   The wire 3 is a linear member having a diameter of about 1 mm, for example. The wire 3 is wound around the coil bobbin 2 in a state where the wires 3 and 3 of each layer are aligned with no gap so that they overlap at the same position. Further, the end portion of the wire 3 is drawn out through a notch portion 13 (described later) formed in the flange portion 12 of the coil bobbin 2.

次に、コイルボビン２の構成について説明する。図３は、コイルボビン２の側面図である。図３に示すように、コイルボビン２は、例えばフェライトやアルミナの混合体を焼成することによって形成され、ワイヤ３が巻き付けられる巻芯１１と、巻芯１１の両端にそれぞれ設けられる一対の鍔部１２，１２とを備えている。   Next, the configuration of the coil bobbin 2 will be described. FIG. 3 is a side view of the coil bobbin 2. As shown in FIG. 3, the coil bobbin 2 is formed, for example, by firing a mixture of ferrite and alumina, and a winding core 11 around which the wire 3 is wound, and a pair of flanges 12 provided at both ends of the winding core 11. , 12.

巻芯１１は、例えば長さ６０ｍｍ、直径３０ｍｍ程度の円筒状をなしている。また、鍔部１２は、例えば直径５０ｍｍ程度の円板状をなしている。鍔部１２には、図４に示すように、ワイヤ３の引き出し口となる幅８ｍｍ程度の切欠部１３が径方向に形成されている。切欠部１３は、鍔部１２の周方向に例えば９０°間隔で計４箇所に設けられている。一方の鍔部１２に形成された切欠部１３と、他方の鍔部１２に形成された切欠部１３とは、巻芯１１の軸方向から見た場合に例えば４５°ずれており、互いに重ならない位置に配置されている。   For example, the core 11 has a cylindrical shape with a length of 60 mm and a diameter of about 30 mm. Moreover, the collar part 12 has comprised the disk shape about 50 mm in diameter, for example. As shown in FIG. 4, the flange portion 12 is formed with a notch portion 13 having a width of about 8 mm that serves as a lead-out port for the wire 3 in the radial direction. The notches 13 are provided in a total of four locations, for example, at 90 ° intervals in the circumferential direction of the flange portion 12. The notch 13 formed in one collar 12 and the notch 13 formed in the other collar 12 are, for example, 45 ° apart when viewed from the axial direction of the core 11 and do not overlap each other. Placed in position.

また、鍔部１２の厚さは、図５に示すように、鍔部１２の周方向で徐々に変化している。より具体的には、例えば鍔部１２の外側面１２ａを巻芯１１の軸方向に直交する基準面Ｓとした場合に、鍔部１２の内側面１２ｂは、基準面Ｓからの距離が周方向で一定の増分で変化している。この結果、内側面１２ｂにおいて、特定の１箇所の切欠部１３を臨む一方の縁部１４と他方の縁部１５との間にワイヤ３の直径と同等の段差Ｄが生じた状態となっており、縁部１５は、縁部１４に対してワイヤ３の１本分だけコイルボビン２の中央側に張り出した状態となっている。   Moreover, the thickness of the collar part 12 is changing gradually in the circumferential direction of the collar part 12, as shown in FIG. More specifically, for example, when the outer surface 12a of the flange portion 12 is a reference surface S orthogonal to the axial direction of the core 11, the inner surface 12b of the flange portion 12 has a distance from the reference surface S in the circumferential direction. It is changing at a constant increment. As a result, in the inner surface 12b, a step D equivalent to the diameter of the wire 3 is generated between one edge 14 facing the specific notch 13 and the other edge 15. The edge 15 protrudes toward the center of the coil bobbin 2 by one wire 3 with respect to the edge 14.

なお、４箇所の切欠部１３のうちの特定の１箇所について、縁部１４の内側面１２ｂ側には、切欠部１３に向かって厚みが薄くなるようなテーパ部１４ａが設けられている。また、この切欠部１３における縁部１５の外側面１２ａ側にも、切欠部１３に向かって厚みが薄くなるようなテーパ部１５ａが設けられている。これらのテーパ部１４ａ，１５ａには、切欠部１３から外部に引き出されるワイヤ３の引き出し部分の基端部を沿わせることができる。   In addition, a taper portion 14 a whose thickness decreases toward the notch portion 13 is provided on the inner surface 12 b side of the edge portion 14 at a specific one of the four notch portions 13. In addition, a tapered portion 15 a whose thickness decreases toward the notch portion 13 is also provided on the outer surface 12 a side of the edge portion 15 in the notch portion 13. These taper portions 14a and 15a can be provided with the base end portion of the lead-out portion of the wire 3 drawn out from the notch portion 13 to the outside.

以上の構成を有する一対の鍔部１２，１２は、内側面１２ｂ，１２ｂが略平行となるように巻芯１１に固定されている（図３参照）。鍔部１２，１２は、周方向で厚みが変化しているが、内側面１２ｂ，１２ｂが略平行となっていることで、内側面１２ｂ，１２ｂ間の距離Ｋは巻芯１１の長さと同等となっており、その全周にわたってワイヤ３の直径の整数倍となっている。   The pair of flange portions 12 and 12 having the above configuration are fixed to the core 11 so that the inner side surfaces 12b and 12b are substantially parallel (see FIG. 3). Although the thicknesses of the flange portions 12 and 12 change in the circumferential direction, the distance K between the inner side surfaces 12b and 12b is equal to the length of the core 11 because the inner side surfaces 12b and 12b are substantially parallel. It is an integral multiple of the diameter of the wire 3 over its entire circumference.

続いて、上述したコイルボビン２の作用効果について説明する。   Then, the effect of the coil bobbin 2 mentioned above is demonstrated.

このコイルボビン２にワイヤ３を巻き付ける場合、まず、一方の鍔部１２の特定の１箇所の切欠部１３にワイヤ３を通し、縁部１４のテーパ部１４ａに沿わせたワイヤ３を内側面１２ｂに沿って屈曲させる。そして、このワイヤ３の屈曲部分を巻き始め部分として、鍔部１２の厚さが厚くなる向きにワイヤ３を巻芯１１に巻き付ける。   When the wire 3 is wound around the coil bobbin 2, first, the wire 3 is passed through one specific notch 13 of the one flange portion 12, and the wire 3 along the tapered portion 14a of the edge portion 14 is applied to the inner surface 12b. Bend along. Then, the wire 3 is wound around the winding core 11 in the direction in which the thickness of the flange portion 12 is increased, with the bent portion of the wire 3 being a winding start portion.

ここで、図６に示すように、鍔部１２の厚さが周方向で一定となっている従来のコイルボビン１０１では、２周目以降に巻き付けられるワイヤ３が、ワイヤ３の屈曲部分３ａの形状に追従して変形してしまうという問題があった。このようなワイヤ３の変形は、ワイヤ３の巻き付けの進行と共に強調されて伝播することがあり、ワイヤ３，３間に隙間が生じる要因となる。ワイヤ３，３間に隙間が生じると、各層のワイヤ３，３同士の位置がずれてしまい、ワイヤ３，３同士を重ねた状態で隙間なく整列させることが困難になる。   Here, as shown in FIG. 6, in the conventional coil bobbin 101 in which the thickness of the flange portion 12 is constant in the circumferential direction, the wire 3 wound after the second round is formed in the shape of the bent portion 3 a of the wire 3. There was a problem that it deformed following the above. Such deformation of the wire 3 may be emphasized and propagated as the winding of the wire 3 progresses, which causes a gap between the wires 3 and 3. When a gap is generated between the wires 3 and 3, the positions of the wires 3 and 3 in each layer are shifted, and it is difficult to align the wires 3 and 3 without gaps in a state where the wires 3 and 3 are overlapped.

これに対し、コイルボビン２では、鍔部１２の内側面１２ｂにおいて、特定の１箇所の切欠部１３を臨む一方の縁部１４と他方の縁部１５との間にワイヤ３の直径と同等の段差Ｄが設けられている。このため、図７に示すように、切欠部１３から導入したワイヤ３を鍔部１２の内側面１２ｂに沿って巻き付ける際に、ワイヤ３の屈曲部分３ａを段差Ｄによってワイヤ３の直径分だけ鍔部１２の外側面１２ａ側にオフセットさせることができる。したがって、このコイルボビン２では、２周目以降に巻き付けられるワイヤ３が、ワイヤ３の屈曲部分３ａの形状に追従して変形することを緩和でき、ワイヤ３，３間に隙間が生じることを抑制できるので、各層のワイヤ３，３同士を重ねた状態で隙間なく整列させることが可能となる。   On the other hand, in the coil bobbin 2, on the inner surface 12 b of the flange portion 12, a step equivalent to the diameter of the wire 3 is formed between one edge portion 14 facing the specific notch 13 and the other edge portion 15. D is provided. Therefore, as shown in FIG. 7, when the wire 3 introduced from the notch 13 is wound along the inner surface 12 b of the flange 12, the bent portion 3 a of the wire 3 is bent by the step D by the diameter of the wire 3. The portion 12 can be offset toward the outer surface 12a. Therefore, in this coil bobbin 2, it is possible to alleviate the deformation of the wire 3 wound around the second and subsequent turns following the shape of the bent portion 3 a of the wire 3, and to suppress the formation of a gap between the wires 3 and 3. Therefore, it is possible to align the wires 3 and 3 of each layer with no gap in a state where the wires 3 and 3 are overlapped.

また、コイルボビン２では、一方の鍔部１２の内側面１２ｂと他方の鍔部１２の内側面１２ｂとの間の距離は、ワイヤ３の直径の整数倍となっている。両鍔部１２，１２の内側面１２ｂ，１２ｂにワイヤ３を密着して沿わせることができる。したがって、好適にワイヤ３を整列させることが可能となる。   Further, in the coil bobbin 2, the distance between the inner side surface 12 b of one flange portion 12 and the inner surface 12 b of the other flange portion 12 is an integral multiple of the diameter of the wire 3. The wire 3 can be brought into close contact with the inner side surfaces 12b, 12b of the both flange portions 12, 12. Therefore, the wires 3 can be suitably aligned.

また、コイルボビン２では、一方の鍔部１２に形成された切欠部１３と他方の鍔部１２に形成された切欠部１３とは、巻芯１１の軸方向から見た場合に互いに重ならない位置に形成されている。これにより、例えば図８に示すように、コイルボビン２をワイヤ巻付装置２１の回転軸２２にセットし、一方の鍔部１２の切欠部１３からワイヤ３を導入し、他方の鍔部１２の切欠部１３からワイヤ３を巻き付ける際の整列ガイド２３を導入する場合に、整列ガイド２３からの押圧力が鍔部１２の肉厚部分（切欠部１３が形成されていない部分）に加わるので、鍔部１２が変形することを防止できる。   Further, in the coil bobbin 2, the cutout portion 13 formed in the one flange portion 12 and the cutout portion 13 formed in the other flange portion 12 are positioned so as not to overlap each other when viewed from the axial direction of the core 11. Is formed. Thus, for example, as shown in FIG. 8, the coil bobbin 2 is set on the rotating shaft 22 of the wire winding device 21, the wire 3 is introduced from the notch 13 of the one collar 12, and the notch of the other collar 12 is When introducing the alignment guide 23 when winding the wire 3 from the portion 13, the pressing force from the alignment guide 23 is applied to the thick portion of the flange portion 12 (the portion where the notch portion 13 is not formed). 12 can be prevented from being deformed.

コイルボビン２にワイヤ３を巻き付けてなるコイル部品１では、各層のワイヤ３，３同士を重ねた状態で隙間なく整列させることで、巻き付けるワイヤ３の長さのばらつきを抑制できる。したがって、コイル部品１の個体間の特性の均一化が図られる。   In the coil component 1 in which the wire 3 is wound around the coil bobbin 2, by arranging the wires 3 and 3 of the respective layers without any gaps in an overlapped state, variations in the length of the wire 3 to be wound can be suppressed. Accordingly, the characteristics of the individual coil parts 1 can be made uniform.
