Description

本発明は、回転電機の分割コアステータ及び分割コアステータ製造方法に関する。   The present invention relates to a split core stator of a rotating electric machine and a split core stator manufacturing method.

複数の分割コアから構成される回転電機の分割コアステータでは、各分割コアに巻回されたコイルから引出される引出し線をバスバーやプリント基板に接続する。しかしながら、上記した回転電機では、複雑な構造のバスバーやプリント基板などによって引出し線を互いに結線するため、部品点数が多くなってコストが増大する。   In a split core stator of a rotating electrical machine composed of a plurality of split cores, a lead wire drawn from a coil wound around each split core is connected to a bus bar or a printed board. However, in the above-described rotating electric machine, since the lead wires are connected to each other by a bus bar or a printed board having a complicated structure, the number of parts increases and the cost increases.

特許文献１に記載の分割コアステータでは、隣接する分割コアからの引出し線同士を簡素な構造のターミナルによって相互に接続する。そのため、バスバーやプリント基板などの専用部品が不要となって、部品点数を削減することができる。
特開２００３−３３３７８１号公報 In the split core stator described in Patent Document 1, the lead wires from adjacent split cores are connected to each other by a terminal having a simple structure. Therefore, dedicated parts such as a bus bar and a printed board are not required, and the number of parts can be reduced.
JP 2003-333781 A

ところで、特許文献１に記載の分割コアステータでは、コイルからの引出し線同士をターミナルによって間接的に結線するので、分割コアステータ製造時にこのターミナルを削減することができない。また、ターミナルと隣接する２つの分割コアからの引出し線とをそれぞれ接続するため、１つのターミナルで２回の引出し線を接続する必要があり、組立工数を低減することができないという問題がある。   By the way, in the split core stator described in Patent Document 1, since the lead wires from the coils are indirectly connected by the terminal, this terminal cannot be reduced when the split core stator is manufactured. In addition, since the terminal and the lead lines from the two divided cores adjacent to each other are connected, it is necessary to connect the lead lines twice with one terminal, and there is a problem that the number of assembling steps cannot be reduced.

そこで、本発明では、部品点数を削減するとともに、製造時の組立工数を低減することができる回転電機の分割コアステータ及び分割コアステータ製造方法を提供することを目的とする。   Therefore, an object of the present invention is to provide a split core stator for a rotating electrical machine and a split core stator manufacturing method that can reduce the number of parts and the number of assembly steps during manufacturing.

本発明は、以下のような解決手段によって前記課題を解決する。なお、理解を容易にするために本発明の実施形態に対応する符号を付するが、これに限定されるものではない。   The present invention solves the above problems by the following means. In addition, in order to make an understanding easy, although the code | symbol corresponding to embodiment of this invention is attached | subjected, it is not limited to this.

本発明は、コイル（５０）が巻き回されたインシュレータ（６０）を有する分割コア（４０）と、前記分割コア（４０）を円環状に配置して、隣接する分割コア（４０）のコイル（５０）を相互に接続する分割コアステータ（３０）であって、前記分割コア（４０）は、前記分割コア（４０）のコイル（５０）から引出され、隣接する一方の分割コア（４０）のコイル（５０）と接続する略Ｕ字形状の接続部（５２ｄ）と、隣接する他方の分割コア（４０）のコイル（５０）の接続部（５２ｄ）が掛かる受け部（５２ａ）とを有するコイル引出し線（５２）と、前記インシュレータ（６０）に形成され、接続時に前記コイル引出し線（５２）の位置決めを行う位置決め手段（６６、６７）と、を備える。   In the present invention, a split core (40) having an insulator (60) around which a coil (50) is wound, and the split core (40) are arranged in an annular shape, and a coil ( 50), and the split core (40) is drawn from the coil (50) of the split core (40) and is adjacent to the split core (40). Coil drawer having a substantially U-shaped connection part (52d) connected to (50) and a receiving part (52a) on which the connection part (52d) of the coil (50) of the other adjacent split core (40) is hooked Line (52) and positioning means (66, 67) formed on the insulator (60) and positioning the coil lead wire (52) when connected.

本発明によれば、隣接する２つの分割コアのコイル引出し線を相互に直接結線するので、バスバーやプリント基板などの専用部品が不要となり、分割コアステータ製造時の部品点数を削減することができ、コストダウンを図ることが可能となる。また、引出し線を１回結線するだけでよく、従来技術のようにターミナルを介して引出し線同士を結線する場合よりも分割コアステータ製造時における組立工数を低減することが可能となる。さらに、インシュレータのフランジに切欠きを形成するので、コイル引出し線の位置決めを確実に行うことができる。   According to the present invention, coil lead wires of two adjacent split cores are directly connected to each other, so that dedicated parts such as a bus bar and a printed board are not required, and the number of parts when manufacturing a split core stator can be reduced. Cost can be reduced. Further, it is only necessary to connect the lead wires once, and it is possible to reduce the number of assembling steps at the time of manufacturing the split core stator as compared with the case where the lead wires are connected through the terminal as in the prior art. Further, since the notch is formed in the flange of the insulator, the coil lead wire can be reliably positioned.

From this coil 50, an outer diameter side lead wire 51 is drawn out on the outer diameter side (hereinafter referred to as "stator outer diameter side") when the split core 40 is arranged in an annular shape. Further, the inner diameter side lead wire 52 is drawn out to the inner diameter side (hereinafter referred to as “stator inner diameter side”) when the split core 40 is arranged in an annular shape. The outer diameter side lead wire 51 is connected to one of the input terminals U, V, and W by an annular input line bus bar (not shown).

分割コア４０は、図２（Ａ）に示すように、電磁鋼板を積層してかしめた積層鋼板４１と、分割コア４０が円環状に配置されたときの径方向（以下「ステータ径方向」）側面を覆うインシュレータ６０とを備える。   As shown in FIG. 2A, the split core 40 includes a laminated steel plate 41 obtained by laminating and crimping electromagnetic steel plates, and a radial direction when the split core 40 is arranged in an annular shape (hereinafter, “stator radial direction”). And an insulator 60 covering the side surface.

このインシュレータ６０は、フランジ６１、６２と、巻枠６３と、突出部６４とから構成される。   The insulator 60 includes flanges 61 and 62, a winding frame 63, and a protruding portion 64.

インシュレータ６０は、ステータ外径側に外径側フランジ６１を形成する。同様に、ステータ内径側に内径側フランジ６２を形成する。そして、図２（Ａ）及び図２（Ｂ）に示すように、外径側フランジ６１と内径側フランジ６２との間の巻枠６３にエナメル線を巻き回して、コイル５０を形成する。また、外径側フランジ６１にはコイル５０からの外径側引出し線５１を通す切欠き６５が形成され、内径側フランジ６２にも同様にコイル５０からの内径側引出し線５２を通す切欠き６６が形成される。   The insulator 60 forms an outer diameter side flange 61 on the outer diameter side of the stator. Similarly, an inner diameter side flange 62 is formed on the inner diameter side of the stator. Then, as shown in FIGS. 2A and 2B, an enamel wire is wound around a winding frame 63 between the outer diameter side flange 61 and the inner diameter side flange 62 to form the coil 50. Further, a notch 65 through which the outer diameter side lead wire 51 from the coil 50 passes is formed in the outer diameter side flange 61, and a notch 66 through which the inner diameter side lead wire 52 from the coil 50 passes similarly. Is formed.

突出部６４は、図２（Ａ）及び図２（Ｂ）に示すように、内径側フランジ６２からステータ径方向の内径側に向かって突出形成される。突出部６４は、分割コア４０が円環状に配置されたときの周方向（以下「ステータ周方向」）に形成された第１溝６７と第２溝６８とを有する。この第１溝６７は、分割コアステータ３０を組立てたときに隣接する分割コア４０の第２溝６８と組み合わさって、コイル５０から引出される内径側引出し線５２をステータ周方向にガイドする。   As shown in FIGS. 2A and 2B, the protruding portion 64 is formed to protrude from the inner diameter side flange 62 toward the inner diameter side in the stator radial direction. The protruding portion 64 has a first groove 67 and a second groove 68 formed in the circumferential direction (hereinafter referred to as “stator circumferential direction”) when the divided core 40 is arranged in an annular shape. The first groove 67 is combined with the second groove 68 of the adjacent divided core 40 when the divided core stator 30 is assembled, and guides the inner diameter side lead wire 52 drawn from the coil 50 in the stator circumferential direction.

また、本実施形態の分割コア４０において、コイル５０から引き出される内径側引出し線５２は、図２（Ｂ）及び図２（Ｃ）に示すように、ステータ内径側に向かって延びる根元部５２ａと、根元部５２ａからステータ周方向へと湾曲する湾曲部５２ｂと、湾曲部５２ｂからステータ周方向に延びる延設部５２ｃと、延設部５２ｃの先端に形成される略Ｕ字形状の先端部５２ｄとを有する。そして、この略Ｕ字形状の先端部５２ｄが、隣接する分割コア４０の内径側引出し線５２と接続する。   In the split core 40 of the present embodiment, the inner diameter side lead wire 52 drawn from the coil 50 has a root portion 52a extending toward the inner diameter side of the stator, as shown in FIGS. 2 (B) and 2 (C). A curved portion 52b that curves from the root portion 52a in the circumferential direction of the stator, an extended portion 52c that extends from the curved portion 52b in the circumferential direction of the stator, and a substantially U-shaped distal end portion 52d that is formed at the distal end of the extended portion 52c. And have. The substantially U-shaped tip 52 d is connected to the inner diameter side lead wire 52 of the adjacent split core 40.

上記した構成の分割コア４０によって分割コアステータ３０を組み立てたときの内径側引出し線５２の結線構造について図３を参照して説明する。以下では、隣接する２つの分割コアの構成を区別するため、説明の便宜上、例えば隣接する一方の分割コアを分割コア４０−１、他方の分割コアを分割コア４０−２のように構成番号に「−１」又は「−２」を付す。   A connection structure of the inner diameter side lead wire 52 when the split core stator 30 is assembled by the split core 40 having the above-described configuration will be described with reference to FIG. In the following, in order to distinguish the configuration of two adjacent divided cores, for convenience of explanation, for example, one adjacent divided core is assigned a configuration number such as a divided core 40-1, and the other divided core is assigned a configuration number such as a divided core 40-2. "-1" or "-2" is attached.

図３は、分割コアステータ３０において、隣接する２つの分割コア４０−１、４０−２からの内径側引出し線５２−１、５２−２を相互に接続するときの結線構造を示す図である。図３（Ａ）は、分割コアステータ３０の内径側引出し線５２−１、５２−２の近傍を拡大した図である。また、図３（Ｂ）は、図３（Ａ）を矢印Ｂ側から見たときの図を示す。   FIG. 3 is a diagram showing a connection structure when the inner diameter side lead wires 52-1 and 52-2 from two adjacent divided cores 40-1 and 40-2 are connected to each other in the divided core stator 30. FIG. 3A is an enlarged view of the vicinity of the inner diameter side lead wires 52-1 and 52-2 of the split core stator 30. FIG. FIG. 3B shows a view when FIG. 3A is viewed from the arrow B side.

分割コア４０−１のコイル５０−１から引出された内径側引出し線５２−１は、図３（Ａ）及び図３（Ｂ）に示すように、内径側フランジ６２−１の切欠き６６−１を通って、突出部６４−１に形成された第１溝６７−１と隣接する分割コア４０−２の突出部６４−２に形成された第２溝６８−２とによってステータ周方向にガイドされる。このようにガイドされた内径側引出し線５２−１は図中下側に押し下げられ、内径側引出し線５２−１の先端部５２ｄ−１が隣接する分割コア４０−２の内径側引出し線５２−２の根元部５２ａ−２に掛かり電気的に接続する。このように内径側引出し線５２−１の先端部５２ｄ−１の略Ｕ形状がフックとしての機能を果たし、内径側引出し線５２−１、５２−２が直接的に接続される。   As shown in FIGS. 3 (A) and 3 (B), the inner diameter side lead wire 52-1 drawn from the coil 50-1 of the split core 40-1 has a notch 66- of the inner diameter side flange 62-1. 1 in the circumferential direction of the stator by the first groove 67-1 formed in the protruding portion 64-1 and the second groove 68-2 formed in the protruding portion 64-2 of the adjacent split core 40-2. Guided. The inner diameter side lead wire 52-1 guided in this way is pushed down in the figure, and the inner diameter side lead wire 52-1 of the split core 40-2 adjacent to the tip end portion 52d-1 of the inner diameter side lead wire 52-1. 2 and is electrically connected to the root portion 52a-2. As described above, the substantially U shape of the distal end portion 52d-1 of the inner diameter side lead wire 52-1 functions as a hook, and the inner diameter side lead wires 52-1 and 52-2 are directly connected.

ここで、図３（Ｂ）に示すように、内径側引出し線５２−１の先端部５２ｄ−１において、略Ｕ字形状の入口部５２ｅ−１の隙間Ａは、エナメル線の直径よりも小さく設定する。このように先端部５２ｄ−１の入口部５２ｅ−１の隙間Ａを素線直径よりも小さくすると、内径側引出し線５２−１がスプリングバックにより図中上方に引っ張られたとしても、隣接する分割コア４０−２の内径側引出し線５２−２からの外れが抑制される。   Here, as shown in FIG. 3B, the gap A of the substantially U-shaped inlet portion 52e-1 is smaller than the diameter of the enamel wire at the distal end portion 52d-1 of the inner diameter side lead wire 52-1. Set. When the gap A of the inlet portion 52e-1 of the tip end portion 52d-1 is made smaller than the strand diameter in this way, even if the inner diameter side lead wire 52-1 is pulled upward in the figure by the spring back, the adjacent divisions Disengagement of the core 40-2 from the inner diameter side lead wire 52-2 is suppressed.

上述した回転電機１００では、以下のようにして分割コアステータ３０を製造する。   In the rotating electrical machine 100 described above, the split core stator 30 is manufactured as follows.

図４は、回転電機１００の分割コアステータ３０の製造方法を示す図である。   FIG. 4 is a diagram illustrating a method for manufacturing the split core stator 30 of the rotating electrical machine 100.

まず、図４（Ａ）に示すように、分割コア４０のコイル５０から外径側引出し線５１と内径側引出し線５２とを引出す。そして、内径側引出し線５２に、ステータ内径側に向かって延びる根元部５２ａと、根元部５２ａらステータ周方向へと湾曲する湾曲部５２ｂと、湾曲部５２ｂから周方向に延びる延設部５２ｃと、略Ｕ字形状の先端部５２ｄとを形成する。また、内径側引出し線５２の先端部５２ｄでは、図４（Ａ）の波線Ａで示す部分の素線の絶縁被覆が除去される。   First, as shown in FIG. 4A, an outer diameter side lead wire 51 and an inner diameter side lead wire 52 are drawn from the coil 50 of the split core 40. Then, a root portion 52a extending toward the stator inner diameter side, a curved portion 52b that curves in the stator circumferential direction from the root portion 52a, and an extending portion 52c that extends in the circumferential direction from the curved portion 52b are provided on the inner diameter side lead wire 52. And a substantially U-shaped tip 52d. In addition, at the tip end portion 52 d of the inner diameter side lead wire 52, the insulation coating of the portion of the wire indicated by the wavy line A in FIG.

先端部５２ｄの素線の被覆を除去した後、分割コア４０を円環状に配置して（図１参照）、図４（Ｂ）に示すように、分割コア４０−１からの内径側引出し線５２−１の延設部５２ｃ−１と先端部５２ｄ−１とを押し下げる。そうすると、内径側引出し線５２−１の延設部５２ｃ−１は、分割コア４０−１の第１溝６７−１と分割コア４０−２の第２溝６８−２とによってステータ周方向に案内され、先端部５２ｄ−１は隣接する分割コア４０−２の内径側引出し線５２−２の根元部５２ａ−２に接続する（接続工程）。このとき、内径側引出し線５２−１は、切欠き６６−１や第１溝６７−１や第２溝６８−２によって位置決めされる（位置決め工程）。   After removing the covering of the strand of the tip 52d, the split core 40 is arranged in an annular shape (see FIG. 1), and the inner diameter side lead wire from the split core 40-1 is shown in FIG. 4 (B). The extending part 52c-1 and the tip part 52d-1 of 52-1 are pushed down. Then, the extending portion 52c-1 of the inner diameter side lead wire 52-1 is guided in the circumferential direction of the stator by the first groove 67-1 of the split core 40-1 and the second groove 68-2 of the split core 40-2. The tip 52d-1 is connected to the root 52a-2 of the inner diameter side lead wire 52-2 of the adjacent split core 40-2 (connection process). At this time, the inner diameter side lead wire 52-1 is positioned by the notch 66-1, the first groove 67-1, and the second groove 68-2 (positioning step).

その後、図４（Ｃ）に示すように、内径側引出し線５２−１、５２−２を相互に接続した状態で、先端部５２ｄ−１の絶縁被覆を除去した部分を圧着かしめ電極２００によって圧着通電して、接続部分を加熱する。これにより、隣接する分割コア４０−１、４０−２の内径側引出し線５２−１、５２−２を電気的に接続し（結線工程）、回転電機１００の分割コアステータ３０を製造する。なお、結線工程は接続工程の後に行うようにしたが、接続工程と同時に行うようにしてもよい。   After that, as shown in FIG. 4C, the portion from which the insulating coating of the tip end portion 52d-1 is removed is crimped by the crimping and crimping electrode 200 while the inner diameter side lead wires 52-1 and 52-2 are connected to each other. Energize to heat the connection. Thereby, the inner diameter side lead wires 52-1 and 52-2 of the adjacent split cores 40-1 and 40-2 are electrically connected (connection process), and the split core stator 30 of the rotating electrical machine 100 is manufactured. In addition, although the connection process was performed after the connection process, it may be performed simultaneously with the connection process.

以上により、第１実施形態の分割コアステータは下記の効果を得ることができる。   As described above, the divided core stator of the first embodiment can obtain the following effects.

隣接する２つの分割コア４０−１、４０−２の内径側引出し線５２−１、５２−２を直接的に結線するので、複雑な構成となるバスバーやプリント基板などの専用部品が不要となり、分割コアステータ製造時の部品点数を削減することができ、コストダウンを図ることが可能となる。また、内径引出し線５２−１、５２−２を１回結線するだけでよく、従来技術のようにターミナルを介して引出し線同士を結線する場合よりも分割コアステータ３０の製造時における組立工数を低減することが可能となる。   Since the inner diameter side lead wires 52-1 and 52-2 of the two adjacent split cores 40-1 and 40-2 are directly connected, dedicated components such as a bus bar and a printed circuit board having a complicated configuration become unnecessary. It is possible to reduce the number of parts when manufacturing the split core stator, and it is possible to reduce the cost. Moreover, it is only necessary to connect the inner diameter lead wires 52-1 and 52-2 once, and the assembly man-hour at the time of manufacturing the split core stator 30 is reduced as compared with the case where the lead wires are connected to each other through a terminal as in the prior art. It becomes possible to do.

また、一方の分割コア４０−１の内径側引出し線５２−１の先端部５２ｄ−１を略Ｕ字形状とし、隣接する他方の分割コア４０−２の内径側引出し線５２−２の根元部５２ａ−２に掛けるようにしたため、内径側引出し線外れを抑制することができる。   Moreover, the front-end | tip part 52d-1 of the inner diameter side leader line 52-1 of one division | segmentation core 40-1 is made into a substantially U shape, and the root part of the inner diameter side extension line 52-2 of the other adjacent division | segmentation core 40-2 is carried out. Since it is hung on 52a-2, it is possible to suppress the disconnection of the inner diameter side lead line.

さらに、インシュレータ６０の内径側フランジ６２の切欠き６６によって内径側引出し線５２を下側から保持するとともに、突出部６４に形成した第１溝６７と第２溝６８とによって内径側引出し線５２をステータ周方向にガイドするようにしたので、内径側引出し線５２の位置決めを確実に行うことができる。   Further, the inner diameter side lead wire 52 is held from below by the notch 66 of the inner diameter side flange 62 of the insulator 60, and the inner diameter side lead wire 52 is formed by the first groove 67 and the second groove 68 formed in the protruding portion 64. Since the guide is provided in the circumferential direction of the stator, the inner diameter side lead wire 52 can be reliably positioned.

（第２実施形態）
図５は、分割コアステータ３０の第２実施形態を示す図である。 (Second Embodiment)
FIG. 5 is a diagram illustrating a second embodiment of the split core stator 30.

分割コアステータ３０の構成は第１実施形態とほぼ同様であるが、分割コア４０のインシュレータ６０の突出部６４の構成において一部相違する。つまり、突出部６４に突起７０を設けるようにしたもので、以下にその相違点を中心に説明する。なお、以下では、隣接する２つの分割コアの構成を区別するため、説明の便宜上、例えば隣接する一方の分割コアを分割コア４０−１、他方の分割コアを分割コア４０−２のように構成番号に「−１」又は「−２」を付す。   The configuration of the split core stator 30 is substantially the same as that of the first embodiment, but is partially different in the configuration of the protruding portion 64 of the insulator 60 of the split core 40. That is, the protrusion 70 is provided on the protrusion 64, and the difference will be mainly described below. In the following, in order to distinguish the configuration of two adjacent split cores, for convenience of explanation, for example, one adjacent split core is configured as a split core 40-1, and the other split core is configured as a split core 40-2. Appends "-1" or "-2" to the number.

図５に示すように、分割コア４０−１のインシュレータ６０−１の突出部６４−１には、積層鋼板４１−１の積層方向と同方向に突出する突起７０−１が形成される。この突起７０−１の端面７１−１は、内径側引出し線５２−１の湾曲部５２ｂ−１に図中下側から当接する。そのため、図５のように、一方の分割コア４０−２の内径側引出し線５２−２を、隣接する他方の分割コア４０−１の内径側引出し線５２−１に接続するときに、内径側引出し線５２−２を押し下げても、内径側引出し線５２−１の湾曲部５２ｂ−１の高さが確実に保持される。   As shown in FIG. 5, a protrusion 70-1 that protrudes in the same direction as the stacking direction of the laminated steel plates 41-1 is formed on the protruding portion 64-1 of the insulator 60-1 of the split core 40-1. The end surface 71-1 of the projection 70-1 contacts the curved portion 52b-1 of the inner diameter side lead wire 52-1 from the lower side in the drawing. Therefore, as shown in FIG. 5, when the inner diameter side lead wire 52-2 of one split core 40-2 is connected to the inner diameter side lead wire 52-1 of the other adjacent split core 40-1, the inner diameter side Even if the lead wire 52-2 is pushed down, the height of the curved portion 52b-1 of the inner diameter side lead wire 52-1 is reliably maintained.

このように、第２実施形態では、インシュレータ６０−１の突出部６４−１に突起７０−１を形成して、内径側引出し線５２−１の湾曲部５２ｂ−１を支持するようにしたので、内径側引出し線５２−１、５２−２同士の接続が容易となり、さらに第１実施形態よりも内径側引出し線５２−１、５２−２の位置決めを確実に行うことができる。   Thus, in 2nd Embodiment, since the protrusion 70-1 was formed in the protrusion part 64-1 of the insulator 60-1, and the curved part 52b-1 of the inner diameter side extraction line 52-1 was supported, it is. The inner diameter side lead wires 52-1 and 52-2 can be easily connected to each other, and the inner diameter side lead wires 52-1 and 52-2 can be more reliably positioned than those in the first embodiment.

（第３実施形態）
図６は、分割コアステータ３０の第３実施形態を示す図である。 (Third embodiment)
FIG. 6 is a diagram illustrating a third embodiment of the split core stator 30.

分割コアステータ３０の構成は第１実施形態とほぼ同様であるが、分割コア４０のインシュレータ６０の突出部６４の構成において一部相違する。つまり、突出部６４に位置決め穴８０を設けるようにしたもので、以下にその相違点を中心に説明する。なお、以下では、隣接する２つの分割コアの構成を区別するため、説明の便宜上、例えば隣接する一方の分割コアを分割コア４０−１、他方の分割コアを分割コア４０−２のように構成番号に「−１」又は「−２」を付す。   The configuration of the split core stator 30 is substantially the same as that of the first embodiment, but is partially different in the configuration of the protruding portion 64 of the insulator 60 of the split core 40. That is, the positioning hole 80 is provided in the protrusion 64, and the difference will be mainly described below. In the following, in order to distinguish the configuration of two adjacent split cores, for convenience of explanation, for example, one adjacent split core is configured as a split core 40-1, and the other split core is configured as a split core 40-2. Appends "-1" or "-2" to the number.

図６に示すように、分割コア４０−１のインシュレータ６０−１の突出部６４−１には、位置決め穴８０−１が形成される。この位置決め穴８０−１の径は、エナメル線の直径と略同程度に設定されている。そして、第３実施形態では、一方の分割コア４０−２の内径側引出し線５２−２の先端部５２ｄ−２を、隣接する他方の分割コア４０−１の内径側引出し線５２−１に掛けて結線するだけでなく、その内径側引出し線５２−２の端５２ｆ−２を位置決め穴８０−１に挿入する。そのため、第３実施形態では、内径側引出し線５２−１、５２−２の位置決めを確実に行うことができる。   As shown in FIG. 6, a positioning hole 80-1 is formed in the protruding portion 64-1 of the insulator 60-1 of the split core 40-1. The diameter of the positioning hole 80-1 is set to be approximately the same as the diameter of the enameled wire. And in 3rd Embodiment, the front-end | tip part 52d-2 of the inner diameter side leader line 52-2 of one division | segmentation core 40-2 is hung on the inner diameter side extraction line 52-1 of the other adjacent division | segmentation core 40-1. In addition, the end 52f-2 of the inner diameter lead wire 52-2 is inserted into the positioning hole 80-1. Therefore, in the third embodiment, the inner diameter side lead wires 52-1 and 52-2 can be reliably positioned.

また、位置決め穴８０−１に内径側引出し線５２−１の端５２ｆ−１を挿入することで、結線工程において内径側引出し線５２−１、５２−２同士の接続部分を手などで押さえて圧着通電する必要がなく、内径側引出し線５２−１、５２−２を相互に接続した状態に保持したまま結線することができるようになって、分割コアステータ３０の組立工数を低減できる。   Further, by inserting the end 52f-1 of the inner diameter side lead wire 52-1 into the positioning hole 80-1, the connecting portion between the inner diameter side lead wires 52-1 and 52-2 is pressed by hand or the like in the connection process. It is not necessary to carry out the crimping current, and the inner diameter side lead wires 52-1 and 52-2 can be connected while being connected to each other, so that the number of assembling steps of the split core stator 30 can be reduced.

本発明は上記した実施形態に限定されずに、その技術的な思想の範囲内において種々の変更がなし得ることは明白である。   It is obvious that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical idea.
