Description

本発明は、巻線部品に関する。   The present invention relates to a winding component.

従来より、巻芯コアに巻線コイルが巻回された巻線部品がある（例えば、下記特許文献１を参照。）。このような巻線部品では、巻線コイルの端部と電気的に接続された電極端子を介して外部からの電力供給が可能となっている。   Conventionally, there is a winding component in which a winding coil is wound around a winding core (see, for example, Patent Document 1 below).

That is, both end portions of each copper wire constituting the winding coil 3 are integrally joined to the electrode terminals 4 at the drawn positions as end portions 3 a of the winding coil 3.

ここで、巻線コイル３と電極端子４との接合部分について、図２〜図５を参照しながら説明する。なお、図２は、図１に示す巻線コイル３と電極端子４との接合部分を拡大して示す斜視図である。図３は、図２に示す巻線コイル３と電極端子４との接合部分を示す断面図である。図４は、図３に示す電極端子４の構成を示す斜視図である。図５は、参考例として示す巻線コイル３と電極端子４との接合部分を示す断面図である。   Here, the joint portion between the winding coil 3 and the electrode terminal 4 will be described with reference to FIGS. 2 is an enlarged perspective view showing a joint portion between the winding coil 3 and the electrode terminal 4 shown in FIG. FIG. 3 is a cross-sectional view showing a joint portion between the winding coil 3 and the electrode terminal 4 shown in FIG. FIG. 4 is a perspective view showing a configuration of the electrode terminal 4 shown in FIG. FIG. 5 is a cross-sectional view showing a joint portion between the winding coil 3 and the electrode terminal 4 shown as a reference example.

電極端子４は、図２、図３及び図４に示すように、巻線コイル３の端部３ａと当接される台座部５と、台座部５に対向して折り曲げられる第１の折曲片６及び第２の折曲片７と、台座部５に当接された巻線コイル３の端部３ａを第１の折曲片６に接近する側へと傾斜させる傾斜部８とを有している。   As shown in FIGS. 2, 3, and 4, the electrode terminal 4 includes a pedestal portion 5 that is in contact with the end portion 3 a of the winding coil 3 and a first bent portion that is bent to face the pedestal portion 5. It has a piece 6 and a second bent piece 7, and an inclined part 8 for inclining the end 3 a of the winding coil 3 abutted against the pedestal part 5 toward the side approaching the first bent piece 6. is doing.

台座部５は、上述したボス部２ｃの形状に沿って折り曲げられた電極端子４の一面により構成されている。台座部５は、ボス部２ｃの一面に対向して平坦な面を形成している。   The pedestal portion 5 is configured by one surface of the electrode terminal 4 bent along the shape of the boss portion 2c described above. The pedestal portion 5 forms a flat surface facing one surface of the boss portion 2c.

第１の折曲片６は、台座部５のフランジ部２ｂと対向する側の端部から延長して設けられている。接合前の第１の折曲片６は、フランジ部２ｂの一面に対向して台座部５に対して略直角に折り曲げられた状態となっている。   The first bent piece 6 is provided so as to extend from the end portion on the side facing the flange portion 2 b of the pedestal portion 5. The first bent piece 6 before joining is in a state of being bent at a substantially right angle with respect to the pedestal portion 5 so as to face one surface of the flange portion 2b.

また、第１の折曲片６は、折り曲げられる部分（以下、折曲部という。）６ａよりも、台座部５と対向させる部分（以下、溶接部という。）６ｂが大きくなるように形成されている。   Moreover, the 1st bending piece 6 is formed so that the part (henceforth a welding part) 6b facing the base part 5 may become larger than the part (henceforth bending part) 6a to be bent. ing.

第２の折曲片７は、第１の折曲片６よりも巻線コイル３の端部３ａの基端側に位置して、台座部５のフランジ部２ｂと対向する側の端部から延長して設けられている。接合前の第２の折曲片７は、フランジ部２ｂの一面に対向して台座部５に対して略直角に折り曲げられた状態となっている。   The second bent piece 7 is located closer to the base end side of the end portion 3 a of the winding coil 3 than the first bent piece 6 and from the end portion on the side facing the flange portion 2 b of the pedestal portion 5. It is extended. The second bent piece 7 before joining is in a state of being bent at a substantially right angle with respect to the pedestal portion 5 so as to face one surface of the flange portion 2b.

また、第２の折曲片７は、カシメ部として、第１の折曲片６（溶接部６ｂ）よりも小さくなるように形成されている。   Moreover, the 2nd bending piece 7 is formed so that it may become smaller than the 1st bending piece 6 (welding part 6b) as a crimping part.

傾斜部８は、台座部５に形成された溝部９によって構成されている。溝部９は、台座部５の巻線コイル３が位置する側の端部から、第１の折曲片６及び第２の折曲片７の折曲方向とは交差（本実施形態では略直交）する方向に亘って設けられている。   The inclined portion 8 is constituted by a groove portion 9 formed in the pedestal portion 5. The groove portion 9 intersects with the bending direction of the first bent piece 6 and the second bent piece 7 from the end portion of the pedestal portion 5 on the side where the winding coil 3 is located (substantially orthogonal in this embodiment). ).

また、溝部９は、互いに逆向きに傾斜した一対の傾斜面９ａを有して断面略Ｖ字状に形成されている。さらに、溝部９は、一対の傾斜面９ａの間に配置される巻線コイル３の端部３ａの先端側に向かって、その深さが漸次浅くなる形状を有している。なお、溝部９の深さについては、最も深い位置において、例えば巻線コイル３の直径に対して０．５〜１倍程度とすることが好ましい。   Moreover, the groove part 9 has a pair of inclined surfaces 9a inclined in opposite directions and is formed in a substantially V-shaped cross section. Further, the groove portion 9 has a shape in which the depth gradually decreases toward the distal end side of the end portion 3a of the winding coil 3 disposed between the pair of inclined surfaces 9a. In addition, about the depth of the groove part 9, it is preferable to set it as about 0.5 to 1 time with respect to the diameter of the winding coil 3, for example in the deepest position.

これにより、傾斜部８は、溝部９に沿って配置された巻線コイル３の端部３ａを直線的に延長させることで、第１の折曲片６に接近する側へと傾斜させることができる。また、巻線コイル３の端部３ａは、溝部９の内側に配置されることによって、台座部５に対する幅方向（Ｙ軸方向）の位置ずれが防止されている。   Accordingly, the inclined portion 8 can be inclined toward the side approaching the first bent piece 6 by linearly extending the end portion 3a of the winding coil 3 disposed along the groove portion 9. it can. Further, the end portion 3 a of the winding coil 3 is disposed inside the groove portion 9, thereby preventing the positional deviation in the width direction (Y-axis direction) with respect to the base portion 5.

また、溝部９の終端部分は、第１の折曲片６と対向する部分よりも第２の折曲片７側に位置することが好ましい。これにより、溝部９の内側に配置された巻線コイル３の端部３ａを第２の折曲片７で挟み込みながら、台座部５の平坦な面と溶接部６ｂ（第１の折曲片６）との間で巻線コイル３の端部３ａを挟み込むことができる。   Moreover, it is preferable that the terminal part of the groove part 9 is located in the 2nd bending piece 7 side rather than the part facing the 1st bending piece 6. FIG. Accordingly, the end portion 3a of the winding coil 3 disposed inside the groove portion 9 is sandwiched between the second bent pieces 7, while the flat surface of the pedestal portion 5 and the welded portion 6b (first bent piece 6). ) Between the ends 3a of the winding coil 3.

以上のような構成を有する本実施形態の巻線部品１では、巻線コイル３の端部３ａと電極端子４とをレーザー溶接により一体に接合することが行われている。具体的には、先ず、巻線コイル３の端部３ａを溝部９（傾斜部８）に沿って配置し、台座部５に当接された巻線コイル３の端部３ａを第１の折曲片６に接近する側へと傾斜した状態とする。   In the winding component 1 of the present embodiment having the above-described configuration, the end 3a of the winding coil 3 and the electrode terminal 4 are integrally joined by laser welding. Specifically, first, the end portion 3a of the winding coil 3 is arranged along the groove portion 9 (inclined portion 8), and the end portion 3a of the winding coil 3 in contact with the pedestal portion 5 is first folded. The state is inclined toward the side approaching the curved piece 6.

次に、この状態から、第２の折曲片７を台座部５に接近する方向へと折り曲げることによって、巻線コイル３の端部３ａを台座部５と第２の折曲片７との間で挟み込まれた状態（カシメた状態）とする。これにより、巻線コイル３の端部３ａは、台座部５に対して位置決め固定（仮固定）される。   Next, from this state, by bending the second bent piece 7 in a direction approaching the pedestal 5, the end 3 a of the winding coil 3 is moved between the pedestal 5 and the second bent piece 7. It is assumed that it is sandwiched between them (crimped state). As a result, the end 3 a of the winding coil 3 is positioned and fixed (temporarily fixed) with respect to the pedestal 5.

次に、この状態から、第１の折曲片６を台座部５に接近する方向へと折り曲げることによって、巻線コイル３の端部３ａを台座部５と溶接部６ｂ（第１の折曲片６）との間で挟み込まれた状態とする。このとき、巻線コイル３の端部３ａは、溶接部６ｂに接近する側へと傾斜しているため、溶接部６ｂとの間に隙間を生じさせることなく、溶接部６ｂと接触した状態とすることができる。   Next, from this state, by bending the first bent piece 6 in a direction approaching the pedestal 5, the end 3 a of the winding coil 3 is connected to the pedestal 5 and the welded portion 6 b (first bent It is assumed that it is sandwiched between the pieces 6). At this time, since the end 3a of the winding coil 3 is inclined toward the side approaching the weld 6b, the end 3a is in contact with the weld 6b without creating a gap with the weld 6b. can do.

次に、この状態から、レーザー溶接により巻線コイル３の端部３ａを溶接部６ｂ（第１の折曲片６）と共に溶融した状態で接合する。これにより、巻線コイル３の端部３ａと電極端子４とを一体に接合することができる。   Next, from this state, the end 3a of the winding coil 3 is joined together with the welded portion 6b (first bent piece 6) by laser welding. Thereby, the edge part 3a of the winding coil 3 and the electrode terminal 4 can be joined integrally.

本実施形態の巻線部品１では、上述した巻線コイル３の端部３ａを溶接部６ｂ（第１の折曲片６）に接近する側へと傾斜させる溝部９（傾斜部８）を設けることによって、巻線コイル３の端部３ａと溶接部６ｂとの間に隙間を生じさせることなく、これらをレーザー溶接により確実に接合させることが可能である。   In the winding component 1 of the present embodiment, a groove portion 9 (inclined portion 8) is provided to incline the end portion 3a of the winding coil 3 described above toward the side closer to the welded portion 6b (first bent piece 6). Thus, it is possible to reliably join these by laser welding without generating a gap between the end 3a of the winding coil 3 and the weld 6b.

一方、このような溝部９（傾斜部８）を台座部５に設けなかった場合には、図５に示すように、巻線コイル３の端部３ａと溶接部６ｂとの間に隙間Ｓが生じることがある。この場合、レーザー溶接時に、溶接部６ｂから巻線コイル３の端部３ａへと伝わる熱が不十分となり、溶接不良を発生させることがある。   On the other hand, when such a groove 9 (inclined part 8) is not provided in the base part 5, as shown in FIG. 5, there is a gap S between the end 3a of the winding coil 3 and the welded part 6b. May occur. In this case, at the time of laser welding, the heat transmitted from the welded part 6b to the end part 3a of the winding coil 3 becomes insufficient, which may cause poor welding.

以上のようにして、本実施形態の巻線部品１では、巻線コイル３の端部３ａと電極端子４との接続信頼性を向上させることが可能である。また、この巻線部品１の歩留まりを向上させることが可能である。   As described above, in the winding component 1 of the present embodiment, the connection reliability between the end 3a of the winding coil 3 and the electrode terminal 4 can be improved. In addition, the yield of the winding component 1 can be improved.

なお、本発明は、上記実施形態のものに必ずしも限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば、上記傾斜部８については、上述したＶ字の溝部９を例示しているが、溝部９の形状については、このような形状に限らず、例えばＵ字状など適宜変更を加えることが可能である。また、溝部９については、その深さが連続的に変化する形状に限らず、その深さが段階的に変化する形状であってもよい。 In addition, this invention is not necessarily limited to the thing of the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, although the V-shaped groove portion 9 described above is illustrated for the inclined portion 8, the shape of the groove portion 9 is not limited to such a shape, and can be appropriately changed, for example, a U-shape. It is. Further, the groove 9 is not limited to a shape whose depth changes continuously, but may be a shape whose depth changes stepwise.
