It is used to guide a plurality of connecting wires 15 connected to the power supply connector 40 and to connect the connecting wires 15 to a connecting wire 16 that further connects to the power connector 40 .

結線板１７は、周方向Ｙに複数に分割された絶縁体からなる台座部１７Ａと、周方向Ｙに隣合う台座部１７Ａ同士を連結する絶縁体からなる連結部１７Ｂと、複数の接続線１５を備える。連結部１７Ｂは、隣合う台座部１７Ａの径方向Ｘの内側端部、かつ、軸方向Ｚの上端部同士を連結している。 The connection plate 17 includes a pedestal portion 17A made of an insulator divided into a plurality of parts in the circumferential direction Y, a connecting portion 17B made of an insulator that connects the pedestal parts 17A adjacent to each other in the circumferential direction Y, and a plurality of connection wires 15. Equipped with. The connecting portion 17B connects the inner end portions in the radial direction X and the upper end portions in the axial direction Z of the adjacent pedestal portions 17A.

台座部１７Ａの上端面１７Ａｓは、径方向Ｘの内側部分の軸方向Ｚの高さが、径方向Ｘの外側部分の軸方向Ｚの高さよりも高く設定されている。そして、台座部１７Ａには周方向Ｙに平行に、複数の接続線１５を案内する複数の案内溝１７ａが設けられている。 In the upper end surface 17As of the pedestal portion 17A, the height in the axial direction Z of the inner part in the radial direction X is set higher than the height in the axial direction Z of the outer part in the radial direction X. A plurality of guide grooves 17a for guiding the plurality of connection lines 15 are provided in the pedestal portion 17A in parallel to the circumferential direction Y.

したがって、各案内溝１７ａの底１７ａｄの軸方向Ｚの位置は、径方向Ｘの外側から内側に向かって、順に高くなる構造になっている。また、同じ径方向Ｘの位置に存在する、各台座部１７Ａの案内溝１７ａの軸方向Ｚの位置は、軸方向Ｚに垂直な同一平面上にある。 Therefore, the position of the bottom 17ad of each guide groove 17a in the axial direction Z becomes higher in order from the outside to the inside in the radial direction X. Further, the positions in the axial direction Z of the guide grooves 17a of each pedestal portion 17A that are located at the same position in the radial direction X are on the same plane perpendicular to the axial direction Z.

図５Ａ～図５Ｃに示すように、隣合う台座部１７Ａの間には空間Ｒ１が存在する。この空間Ｒ１は、三相交流のＵ、Ｖ、Ｗ相のコイル群を形成し、更にこれらを中性点に接続する複数の接続線１５を作る過程において、導体Ｗを切断するために使用する。 As shown in FIGS. 5A to 5C, a space R1 exists between adjacent pedestals 17A. This space R1 is used to cut the conductor W in the process of forming a group of U, V, and W phase coils of a three-phase AC, and also creating a plurality of connection wires 15 that connect these to a neutral point. .

図５Ｂ、図５Ｃに示すように、結線板１７を径方向Ｘに見た側面図において、連結部１７Ｂの軸方向Ｚの下には、径方向Ｘに貫通する空間Ｒ２が存在する。空間Ｒ２は、接続線１５の溶接時に、ステータ１０の内側から、溶接用の電極を、結線板１７の下部へ挿入するために使用する。 As shown in FIGS. 5B and 5C, in a side view of the connection plate 17 viewed in the radial direction X, a space R2 penetrating in the radial direction X exists below the connecting portion 17B in the axial direction Z. The space R2 is used for inserting a welding electrode into the lower part of the connection plate 17 from inside the stator 10 when welding the connection wire 15.

また、連結部１７Ｂの径方向Ｘの外周面１７Ｂｏｕｔは、台座部１７Ａの最も径方向Ｘの内側に存在する案内溝１７ａの内側側面１７ａｉｎよりも径方向Ｘの内側に凹んでいる。これは、接続線１５の溶接時に、軸方向Ｚの上方から接続線１５に接触する電極が連結部１７Ｂに干渉することを防止するための構造である。 Further, the outer circumferential surface 17Bout of the connecting portion 17B in the radial direction X is recessed inward in the radial direction X from the inner side surface 17ain of the guide groove 17a that is located on the innermost side in the radial direction X of the pedestal portion 17A. This is a structure for preventing the electrode that contacts the connection wire 15 from above in the axial direction Z from interfering with the connecting portion 17B when welding the connection wire 15.

１つの台座部１７Ａの内壁の軸方向Ｚの上方端部には、係止部１７ｋが設けられている。係止部１７ｋは、予め螺旋状に形成された導体Ｗを、径方向Ｘに複数形成された案内溝１７ａに配置する際に、その巻き始め端部Ｓを係止するために使用する。なお、係止部１７ｋを設けた台座部１７Ａには、案内溝１７ａを設けていない。また、以下の説明では係止部１７ｋは、径方向Ｘの内側に設けているが、外側に設けてもよい。 A locking portion 17k is provided at the upper end in the axial direction Z of the inner wall of one pedestal portion 17A. The locking portion 17k is used to lock the winding start end S of the conductor W formed in a spiral shape in advance when the conductor W is arranged in the guide grooves 17a formed in plurality in the radial direction X. Note that the guide groove 17a is not provided in the pedestal portion 17A provided with the locking portion 17k. Further, in the following explanation, the locking portion 17k is provided on the inside in the radial direction X, but it may be provided on the outside.

図６は、接続線１５の形成工程および、結線板１７とコイル１２との接続工程を示すフローチャートである。
図７は、結線板１７の台座部１７Ａ上に、導体Ｗを固定した状態を示す平面図である。
まず、１本の導体Ｗの巻き始め端部Ｓを係止部１７ｋに固定する。ここで、予め螺旋状に形成された１本の導体Ｗを接線板１７上に配置すると、３周ある導体Ｗの内側から１周目部分は、周方向Ｙに時計回りに隣の台座部１７Ａから始めて、径方向Ｘの最も内側の案内溝１７ａの中に周方向Ｙに平行に（ステータ１０と同心に）収納される。導体Ｗのうち、最も内側の１周目の案内溝１７ａに配置される１周目部分は、ステータ１０の軸心に対して同心に配置される。 FIG. 6 is a flowchart showing the process of forming the connection wire 15 and the process of connecting the connection plate 17 and the coil 12.
FIG. 7 is a plan view showing a state in which the conductor W is fixed on the pedestal portion 17A of the wiring board 17.
First, the winding start end S of one conductor W is fixed to the locking part 17k. Here, when one conductor W formed in a spiral shape in advance is arranged on the tangent plate 17, the first round from the inside of the conductor W, which has three rounds, is rotated clockwise in the circumferential direction Y to the adjacent pedestal part 17A. Starting from , it is accommodated in the innermost guide groove 17a in the radial direction X in parallel to the circumferential direction Y (concentrically with the stator 10). The first round portion of the conductor W, which is arranged in the innermost first round guide groove 17a, is arranged concentrically with respect to the axis of the stator 10.

係止部１７ｋを備える台座部１７Ａには、案内溝１７ａが存在しないので、この台座部１７Ａの上で、導体Ｗの２周目となる部分が径方向Ｘに位置を変える。そして、１周目部分と同様に、導体Ｗの内側から２周目部分は、係止部１７ｋを備える台座部１７Ａ以外の全ての台座部１７Ａの、径方向Ｘの内側から２番目の案内溝１７ａの中に周方向Ｙに平行に収納される。導体Ｗの内側から３周目部分は、同様に、径方向Ｘの内側から３番目の案内溝１７ａの中に周方向Ｙに平行に収納される。なお、厳密には、最後の３周目部分は、係止部１７ｋの存在する台座部１７Ａから２つ手前の台座部１７Ａまで配置される（ＳＴ００１：導体配置工程）。 Since the guide groove 17a does not exist in the pedestal part 17A including the locking part 17k, the second round of the conductor W changes its position in the radial direction X on the pedestal part 17A. Similarly to the first round part, the second round part from the inside of the conductor W is the second guide groove from the inside in the radial direction 17a in parallel to the circumferential direction Y. Similarly, the third circumferential portion of the conductor W from the inner side is accommodated in the third guide groove 17a from the inner side in the radial direction X in parallel to the circumferential direction Y. Strictly speaking, the third and final round portion is arranged from the pedestal part 17A where the locking part 17k is present to the pedestal part 17A two places before (ST001: conductor arrangement step).

このように、１本の導体Ｗを複数の台座部１７Ａに配置した後、台座部１７Ａと導体Ｗとに接着剤１９を塗布して、導体Ｗを台座部１７Ａに接着、固定する（ＳＴ００２：導体固定工程）。 In this way, after arranging one conductor W on the plurality of pedestals 17A, adhesive 19 is applied to the pedestals 17A and the conductors W to adhere and fix the conductors W to the pedestals 17A (ST002: conductor fixing process).

図８は、台座部１７Ａに固定後の導体Ｗを切断し、複数の接続線１５を形成した状態を示す図である。
図９は、実施の形態１によるコイル１２の結線図である。
図１０は、円環状に配置した複数のコイル巻装体１１Ａを、フレーム６０に嵌合した状態を示す斜視図である。 FIG. 8 is a diagram showing a state in which the conductor W after being fixed to the pedestal portion 17A is cut to form a plurality of connection wires 15.
FIG. 9 is a wiring diagram of the coil 12 according to the first embodiment.
FIG. 10 is a perspective view showing a state in which a plurality of coil wrapping bodies 11A arranged in an annular shape are fitted into a frame 60.

図９に示すように、本実施の形態では、各相の２個のコイル１２が並列接続され、３相Ｙ結線されている。そこで、三相交流のＵ、Ｖ、Ｗ相のコイル群を形成し、更にこれらを中性点に接続する複数の接続線１５を作るために、図７のように導体Ｗを台座部１７Ａに固定した後、結線板１７の隣合う台座部１７Ａ間の空間Ｒ１にパンチのダイを挿入し、パンチで導体Ｗを軸方向Ｚの上から打ち抜いて切断する（ＳＴ００３：導体切断工程）。このとき、３周ある導体Ｗの最も内側の１周目部分は、図８に示すように、係止部１７ｋから時計回りに１５°１６５°３４５°の位置で切断する。このように、全ての切断部Ｃは、周方向Ｙに隣合う２つの台座部１７Ａの間に設ける。 As shown in FIG. 9, in this embodiment, two coils 12 of each phase are connected in parallel to form a three-phase Y connection. Therefore, in order to form a coil group of U, V, and W phases of three-phase AC, and to make a plurality of connection wires 15 to connect these to the neutral point, conductor W is attached to pedestal part 17A as shown in FIG. After fixing, a die of a punch is inserted into the space R1 between the adjacent pedestals 17A of the wiring board 17, and the conductor W is punched out from above in the axial direction Z using the punch to cut it (ST003: conductor cutting step). At this time, the innermost first round portion of the conductor W, which has three rounds, is cut at a position of 15°, 165°, and 345° clockwise from the locking portion 17k, as shown in FIG. In this way, all the cutting parts C are provided between the two pedestal parts 17A adjacent in the circumferential direction Y.

また、導体Ｗの内側から２周目部分は、係止部１７ｋから時計回りに４５°、２８５°の位置で切断する。同様に、導体Ｗの最も外側の３周目部分は、係止部１７ｋから時計回りに１３５°、３１５°の位置で切断する。導体Ｗを台座部１７Ａに固定した後、このように切断することによって、Ｕ、Ｖ、Ｗ相のコイル群を形成し、更にこれらを中性点に接続する複数の接続線１５を備える結線板１７を得る。 Further, the second round portion from the inside of the conductor W is cut at positions of 45° and 285° clockwise from the locking portion 17k. Similarly, the outermost third round portion of the conductor W is cut at positions of 135° and 315° clockwise from the locking portion 17k. After fixing the conductor W to the pedestal part 17A, the conductor W is cut in this way to form a group of U, V, and W phase coils, and is further provided with a plurality of connection wires 15 that connect these to a neutral point. Get 17.

次に、完成した結線板１７を、円環状に配置した複数のコイル巻装体１１Ａの上に配置する（ＳＴ００４：結線板配置工程）。結線板１７は、結線側インシュレータ１３の内鍔部１３ｃの軸方向Ｚの端面１３ｃｓと、外鍔部１３ａの軸方向Ｚの端面１３ａｓの径方向Ｘの内側の縁１３ｆ上に配置される。 Next, the completed wiring board 17 is placed on the plurality of coil winding bodies 11A arranged in an annular shape (ST004: wiring board arrangement step). The connection plate 17 is arranged on the inner edge 13f in the radial direction X of the end surface 13cs in the axial direction Z of the inner flange 13c of the connection side insulator 13 and the end surface 13as in the axial direction Z of the outer flange 13a.

なお、結線板配置工程と、次に説明する接続線１５と、コイル巻装体１１Ａのコイル１２の端末線１２ｔとの結線は、複数のコイル巻装体１１Ａが、図１０に示すようにフレーム６０に嵌合された状態で行われる。 In addition, in the connection plate arrangement process and the connection between the connection wire 15 described next and the terminal wire 12t of the coil 12 of the coil winding body 11A, the plurality of coil winding bodies 11A are connected to the frame as shown in FIG. 60 is fitted.

図１１は、結線板１７とコイル巻装体１１Ａの溶接前の要部断面図である。
次に、各コイル１２の端末線１２ｔの被膜を剥離し、端末線１２ｔを結線側インシュレータ１３の第２突起１３ｐ２の外周面に沿って引き回して軸方向Ｚの上方へ折り曲げ、更に径方向Ｘの内側に折り曲げて、結線板１７の接続線１５の被膜を剥離した部分の上に配置する。すなわち、図１１に示すように、端末線１２ｔは、図１０の状態から、先端が径方向Ｘの内側に折り曲げられて溶接対象となる接続線１５の軸方向Ｚの上方に配置される（ＳＴ００５：端末線配置工程）。同様に、全てのコイル巻装体１１Ａの端末線１２ｔを引き回し、結線板１７の接続線１５上に配置する。 FIG. 11 is a sectional view of the main parts of the connection plate 17 and the coil winding body 11A before welding.
Next, the coating of the terminal wire 12t of each coil 12 is peeled off, the terminal wire 12t is routed along the outer peripheral surface of the second protrusion 13p2 of the connection side insulator 13, bent upward in the axial direction Z, and further in the radial direction X. It is bent inward and placed on the portion of the connection plate 17 from which the coating of the connection wire 15 has been peeled off. That is, as shown in FIG. 11, the terminal wire 12t is bent inward in the radial direction X from the state shown in FIG. 10, and is placed above the connection wire 15 to be welded in the axial direction Z (ST005 :Terminal line placement process). Similarly, the terminal wires 12t of all the coil winding bodies 11A are routed and arranged on the connection wires 15 of the connection board 17.

次に、第１電極７０ｉｎを径方向Ｘの内側から、上述の空間Ｒ２の中を通して溶接対象の接続線１５の軸方向Ｚの下に差し込む。次に、第２電極７０ｕを、溶接対象となる端末線１２ｔの軸方向Ｚの上方から、第１電極７０ｉｎの上面との間に、溶接対象となる接続線１５および端末線１２ｔを、軸方向Ｚに挟むように下ろして双方を溶接する（ＳＴ００６：接続工程）。 Next, the first electrode 70 inches is inserted from inside in the radial direction X through the above-mentioned space R2 and under the connection wire 15 to be welded in the axial direction Z. Next, connect the second electrode 70u from above the terminal wire 12t to be welded in the axial direction Z to the upper surface of the first electrode 70in, and connect the connection wire 15 and the terminal wire 12t to be welded in the axial direction. Lower it so that it is sandwiched between Z and weld both sides (ST006: connection process).

同様に、Ｕ、Ｖ、Ｗ相の接続線１５に電源コネクタ４０から電流を供給するための接続線１６の端末の被覆を剥離した後、接続線１５の被膜を剥離した部分の上に配置して溶接する。なお、本実施の形態では、溶接としたが、結線部材を用い、空間Ｒ１、Ｒ２に治具を挿入して結線してもよい。 Similarly, after peeling off the coating at the end of the connection wire 16 for supplying current from the power connector 40 to the U, V, and W phase connection wires 15, the coating is placed on the portion of the connection wire 15 from which the coating has been peeled off. and weld. Although welding is used in this embodiment, the wires may be connected by using a wire connection member and inserting a jig into the spaces R1 and R2.

図１２は、モールドしたステータ１０の斜視図である。
全ての端末線１２ｔを結線板１７の接続線１５に溶接した後、ステータ１０を絶縁樹脂９０でモールドして各溶接部を絶縁する。絶縁樹脂でモールドすることによって、振動により溶接部が破断することも防止できる。 FIG. 12 is a perspective view of the molded stator 10.
After welding all the terminal wires 12t to the connection wires 15 of the connection plate 17, the stator 10 is molded with insulating resin 90 to insulate each welded portion. Molding with insulating resin also prevents the welded portion from breaking due to vibration.

従来の結線板では、渦巻状の導体が、軸方向Ｚに垂直な同一平面上に配置されていたため、導体の上端部が、軸方向Ｚに同じ高さであった。このため、結線のためにステータのコイルの端末線をステータの外側から引き回して溶接する際に、溶接する接続線以外の接続線に干渉し、溶接できなかった。 In the conventional wiring board, the spiral conductors were arranged on the same plane perpendicular to the axial direction Z, so the upper ends of the conductors were at the same height in the axial direction Z. For this reason, when the terminal wires of the stator coils were routed from the outside of the stator for connection and welded, they interfered with connection wires other than the connection wires to be welded, and welding could not be performed.

一方、本実施の形態１による回転電機のステータの結線板、回転電機のステータ、回転電機、回転電機のステータの結線板の製造方法、回転電機のステータの製造方法および回転電機の製造方法によれば、コイル１２の端末線１２ｔを接続する接続線１５は、径方向Ｘの内側ほど軸方向Ｚの高さが高くなっているので、接続線１５とコイル１２の端末線１２ｔとを溶接する際に、ステータ１０の内側から挿入される第１電極７０ｉｎが、他の接続線１５に干渉することがなく、双方の溶接が可能となる。 On the other hand, according to the first embodiment, the stator of a rotating electric machine, the stator of a rotating electric machine, a rotating electric machine, a method of manufacturing a connection plate of a stator of a rotating electric machine, a method of manufacturing a stator of a rotating electric machine, and a method of manufacturing a rotating electric machine. For example, the connection wire 15 that connects the terminal wire 12t of the coil 12 has a height in the axial direction Z that increases toward the inside in the radial direction X, so when welding the connection wire 15 and the terminal wire 12t of the coil 12, In addition, the first electrode 70 inches inserted from the inside of the stator 10 does not interfere with other connection wires 15, making it possible to weld both.

また、図１１に示すように導体Ｗを、軸方向Ｚにずらして、配置することによって、径方向Ｘに隣合う導体Ｗ間の距離が大きくなり、導体Ｗを平面状に成形するよりも導体Ｗ間の絶縁距離を長く確保しつつ径方向Ｘの間隔は縮めることができるので、ステータ１０の径を小さくすることができ、回転電機１００の小型化が可能である。 Furthermore, by arranging the conductors W by shifting them in the axial direction Z as shown in FIG. 11, the distance between the conductors W adjacent to each other in the radial direction Since the interval in the radial direction X can be reduced while ensuring a long insulation distance between the Ws, the diameter of the stator 10 can be reduced, and the rotating electric machine 100 can be downsized.

また、絶縁樹脂を用いて台座部１７Ａ、連結部１７Ｂを形成できるので製造の自由度および搬送性が高く、結線板の組立の効率を向上できる。なお、台座部１７Ａの案内溝１７ａの溝の深さは、図１１に示すように導体Ｗが崩れずに収納できればよい。 Further, since the pedestal portion 17A and the connecting portion 17B can be formed using insulating resin, the degree of freedom in manufacturing and transportability is high, and the efficiency of assembling the wiring board can be improved. Note that the depth of the guide groove 17a of the pedestal portion 17A should be such that the conductor W can be accommodated without collapsing as shown in FIG.

That is, in the first embodiment, the conductor W is wound about three times, but in the second embodiment, it is wound about four times. Therefore, the number of guide grooves 217a formed in the base portion 217A is also four.

本実施の形態では、Ｕ、Ｖ、Ｗ相のコイル群を形成する接続線１５と、中性点を形成する接続線１５と、電源からの給電線を接続する部分の被膜を中間で剥離している。実施の形態１と同様に、１本の導体Ｗが軸方向Ｚの高さ違い、かつ、径方向Ｘの径違いに４重に並んでおり、軸方向Ｚの高さの違う部分を繋ぐ部分が存在する。 In this embodiment, the coating of the connecting wire 15 forming the U, V, and W phase coil groups, the connecting wire 15 forming the neutral point, and the portion connecting the feeder line from the power source is peeled off in the middle. ing.

The innermost first round portion of the conductor W, which has four rounds, is cut at positions of 15°, 135°, 225°, and 345° clockwise from the locking portion 17k.

また、内側から２周目部分は、係止部１７ｋから時計回りに１５°、２２５°の位置で切断する。同様に、内側から３週目部分は、係止部１７ｋから時計回りに１３５°、３４５°の位置で切断する。そして最も外側の４周目部分は、係止部１７ｋから時計回りに１５°の位置で切断する。そして、Ｕ、Ｖ、Ｗ相のコイル群を形成し、更にこれらを中性点に接続する複数の接続線１５を備える結線板２１７を得る。 Further, the second circumference from the inside is cut at positions 15° and 225° clockwise from the locking portion 17k. Similarly, the third week portion from the inside is cut at positions 135° and 345° clockwise from the locking portion 17k. The outermost fourth round portion is cut at a position 15° clockwise from the locking portion 17k. Then, a wiring board 217 is obtained which forms coil groups of U, V, and W phases and further includes a plurality of connecting wires 15 that connect these to a neutral point.

次に、完成した結線板２１７を、円環状に配置した複数のコイル巻装体１１Ａの上に配置する。結線板２１７は、結線側インシュレータ１３の内鍔部１３ｃの軸方向Ｚの端面１３ｃｓと、外鍔部１３ａの軸方向Ｚの端面１３ａｓの径方向Ｘの内側の縁１３ｆ上に配置される。以降の工程は、実施の形態１と同様である。 Next, the completed wiring board 217 is placed on the plurality of coil winding bodies 11A arranged in an annular shape. The connection plate 217 is arranged on the inner edge 13f in the radial direction X of the end surface 13cs in the axial direction Z of the inner flange 13c of the connection side insulator 13 and the end surface 13as in the axial direction Z of the outer flange 13a.
