　固定子組立３０は、環状の固定子１０と、固定子１０の軸方向の一端にて固定子１０に組付けられ、センサリード線７及び電源リード線８が配線されたリード線配線部品１と、リード線配線部品１に組付けられ、ボードインコネクタ８０を介してセンサリード線７が接続されるセンサ基板１１（基板）と、センサリード線７及び電源リード線８を口出しするリード線口出し部品６と、リード線口出し部品６に組付けられ、電源リード線８を保持する電源リード線保持部品４と、リード線口出し部品６に組付けられ、センサリード線７を保持するセンサリード線保持部品５とを備える（図１）。 The stator assembly 30 includes an annular stator 10 and a lead wire wiring component 1 that is assembled to the stator 10 at one end in the axial direction of the stator 10 and to which the sensor lead wire 7 and the power supply lead wire 8 are wired. The sensor substrate 11 (substrate) assembled to the lead wire wiring component 1 and connected to the sensor lead wire 7 via the board-in connector 80, and the lead wire lead-out component for extracting the sensor lead wire 7 and the power supply lead wire 8. 6 and the lead wire lead-out component 6 to hold the power lead wire 8 and the power supply lead wire holding component 4 and the lead wire lead-out component 6 to hold the sensor lead wire 7 and the sensor lead wire holding component. 5 (FIG. 1).
　固定子１０は、電磁鋼板が帯状に打ち抜かれ、かしめ、溶接、及び接着等で積層して形成される固定子鉄心８２と、固定子鉄心８２に施された絶縁部８３と、固定子鉄心８２のティース３１に施された絶縁部８３にマグネットワイヤが巻き付けられて成るコイル８４と、絶縁部８３により支持された端子１２とを備える。 The stator 10 includes a stator core 82 that is formed by punching electromagnetic steel sheets into a band shape and laminated by caulking, welding, adhesion, or the like, an insulating portion 83 that is applied to the stator core 82, and a stator core 82. A coil 84 formed by winding a magnet wire around an insulating portion 83 provided on the tooth 31 and a terminal 12 supported by the insulating portion 83.
　絶縁部８３は、ＰＢＴ（ポリブチレンテレフタレート）等の熱可塑性樹脂を固定子鉄心８２と一体に成形され、又は成形後に固定子１０に組付けることで施される。マグネットワイヤの端末の一方は、端子１２のフック部８５に引回され、ヒュージングあるいは、半田等でフック部８５に接合され、端末の他方は各相まとめられて中性点を形成する。絶縁部８３、コイル８４、及び端子１２等が設けられた固定子鉄心８２を構成する帯状のコアを環状に曲げ、突合せ部を溶接することで固定子１０が構成される。 The insulating part 83 is formed by molding a thermoplastic resin such as PBT (polybutylene terephthalate) integrally with the stator core 82 or by assembling the stator 10 after the molding. One end of the magnet wire is drawn around the hook portion 85 of the terminal 12 and joined to the hook portion 85 by fusing or soldering, and the other end of the end is combined with each other to form a neutral point. The stator 10 is configured by bending a belt-shaped core constituting the stator core 82 provided with the insulating portion 83, the coil 84, the terminal 12, and the like into an annular shape and welding the butted portions.
　なお、以下では、固定子鉄心８２の軸方向における端子１２を備える側を結線側、その反対側を反結線側という。また、「軸方向」は、固定子鉄心８２の軸方向である。 In the following, the side including the terminal 12 in the axial direction of the stator core 82 is referred to as a connection side, and the opposite side is referred to as an anti-connection side. The “axial direction” is the axial direction of the stator core 82.
　絶縁部８３を構成する絶縁外壁８３ａは、コイル８４が外周側に倒れるのを防止する。絶縁外壁８３ａの結線側には、リード線配線部品１を固定子１０に取り付けるための複数のピン８１が設けられている（図６）。絶縁部８３を構成する絶縁内壁８３ｂは、コイル８４が内周側に倒れるのを防止する。絶縁内壁８３ｂの反結線側には、突起（図示せず）が設けられている。この反結線側に設けられた突起（図示せず）は、モールド成形時に固定子１０が金型芯金部に設置された際に、金型芯金部に当接して軸方向の当て止めとして使用される。 The insulating outer wall 83a constituting the insulating portion 83 prevents the coil 84 from falling to the outer peripheral side. A plurality of pins 81 for attaching the lead wire wiring component 1 to the stator 10 are provided on the connection side of the insulating outer wall 83a (FIG. 6). The insulating inner wall 83b that constitutes the insulating portion 83 prevents the coil 84 from falling to the inner peripheral side. A protrusion (not shown) is provided on the side opposite to the insulating inner wall 83b. A protrusion (not shown) provided on the side opposite to the connection side is in contact with the die core member when the stator 10 is placed on the die core member during molding, and serves as an axial stopper. used.
　なお、絶縁外壁８３ａは、その軸方向の長さがコイル８４よりも若干長くなるように形成され、絶縁外壁８３ａの反結線側の高さもコイル８４の反結線側の高さよりも若干高い。また、コイル８４は、その軸方向の長さが絶縁外壁８３ａから絶縁内壁８３ｂに向かうにつれて短くなるように形成され、その反結線側の高さも絶縁外壁８３ａから絶縁内壁８３ｂに向かうにつれて低くなる。絶縁内壁８３ｂの反結線側の突起（図示せず）の高さを、絶縁外壁８３ａの反結線側の高さと同じにした場合、固定子１０の反結線側の端からコイル８４までの軸方向の距離を十分に確保することができる。この場合、固定子１０の反結線側を下にした状態で固定子１０を金型芯金部に設置したとき、コイル８４が金型芯金部に当たることなく、固定子１０を安定して置くことが可能となり、生産性の向上が図れ、それに伴い品質も向上する。 The insulating outer wall 83a is formed so that its axial length is slightly longer than that of the coil 84, and the height of the insulating outer wall 83a on the anti-connection side is slightly higher than the height of the coil 84 on the anti-connection side. Further, the coil 84 is formed such that its axial length becomes shorter as it goes from the insulating outer wall 83a toward the insulating inner wall 83b, and its height on the anti-connection side becomes lower as it goes from the insulating outer wall 83a toward the insulating inner wall 83b. When the height of the protrusion (not shown) on the anti-connection side of the insulating inner wall 83b is the same as the height of the anti-connection side of the insulating outer wall 83a, the axial direction from the end of the anti-connection side of the stator 10 to the coil 84 It is possible to secure a sufficient distance. In this case, when the stator 10 is installed on the die core member with the anti-connection side of the stator 10 facing down, the stator 10 is stably placed without the coil 84 hitting the die core member. It is possible to improve productivity and quality accordingly.

In FIG. 2, the lead wire assembly 90 is viewed from the stator 10 side.
　電源リード線８は、電源（図示せず）に接続されて、コイル８４に電力を供給する。電源リード線８は、マグネットワイヤの端末が接合された端子１２まで引回され、被覆を剥いて端子１２とスポット溶接、あるいは、半田等で接合される。 The power supply lead 8 is connected to a power supply (not shown) and supplies power to the coil 84. The power supply lead 8 is routed to the terminal 12 to which the end of the magnet wire is joined, and the coating is peeled off and joined to the terminal 12 by spot welding or soldering.
　センサ基板１１には、ホールＩＣ３２等の電子部品が実装されている。回転子の位置検出素子（回路）としてのホールＩＣ３２は、センサ基板１１の反結線側の面に実装される。 An electronic component such as a Hall IC 32 is mounted on the sensor substrate 11. The Hall IC 32 as a rotor position detection element (circuit) is mounted on the surface of the sensor substrate 11 on the side opposite to the connection.
　センサリード線７の端末は、ボードインコネクタ８０に接続される。この場合の端末は、モールド内部となる側の端末である。ボードインコネクタ８０は、センサ基板１１の結線側の面に設置され、基板表面に表出したボードインコネクタ８０の端子がセンサ基板１１に半田接合される。これにより、センサリード線７は、ボードインコネクタ８０を介して、センサ基板１１上の電子部品と電気的に接続される。 The terminal of the sensor lead wire 7 is connected to the board-in connector 80. The terminal in this case is a terminal on the side that is inside the mold. The board-in connector 80 is installed on the surface on the connection side of the sensor substrate 11, and the terminals of the board-in connector 80 exposed on the substrate surface are soldered to the sensor substrate 11. Thereby, the sensor lead wire 7 is electrically connected to the electronic component on the sensor substrate 11 via the board-in connector 80.
　電源リード線８及びセンサリード線７の配線にはリード線配線部品１が用いられ、電源リード線８及びセンサリード線７はリード線配線部品１の外周に組付けられたリード線口出し部品６から固定子１０の外部に表出される。 The lead wire wiring component 1 is used for the wiring of the power supply lead wire 8 and the sensor lead wire 7, and the power supply lead wire 8 and the sensor lead wire 7 are connected to the lead wire wiring component 1 from the lead wire lead-out component 6. Expressed outside the stator 10.
　リード線配線部品１は、環状板部１ａ、内壁１ｂ、取付け足１３、突起１４、リード線端末保持部１５、組付け足１７ａ，１７ｂ、凹部１８、位置ずれ防止用突起１９、及び芯線保持部２０を備える（図３、図５）。 The lead wire wiring component 1 includes an annular plate portion 1a, an inner wall 1b, a mounting foot 13, a projection 14, a lead wire terminal holding portion 15, assembly feet 17a and 17b, a recess portion 18, a misalignment preventing projection 19, and a core wire holding portion. 20 (FIGS. 3 and 5).
　環状板部１ａは、ＰＢＴ等の熱可塑性樹脂を成形して環状に形成されている。環状板部１ａの外周側には、固定子１０にリード線配線部品１を組付ける際に使用される複数個の取付け足１３が設けられている。取付け足１３の個数は例えば４個である。取付け足１３には、端子１２を挿入するための穴１３ａが形成されている。取付け足１３は、リード線配線部品１が固定子１０に組付けられた際に、固定子１０の絶縁部８３の設置面に当接する。これにより、リード線配線部品１の軸方向の位置決めがなされる。また、ピン８１が取付け足１３の穴１３ａに挿入されることで、リード線配線部品１の回転方向の位置決めがなされる。 The annular plate portion 1a is formed in an annular shape by molding a thermoplastic resin such as PBT. On the outer peripheral side of the annular plate portion 1a, a plurality of mounting legs 13 used when the lead wire wiring component 1 is assembled to the stator 10 are provided. The number of mounting feet 13 is, for example, four. A hole 13 a for inserting the terminal 12 is formed in the mounting foot 13. When the lead wire wiring component 1 is assembled to the stator 10, the mounting foot 13 contacts the installation surface of the insulating portion 83 of the stator 10. Thereby, the lead wire wiring component 1 is positioned in the axial direction. Further, the lead 81 is inserted into the hole 13a of the mounting foot 13 so that the lead wire wiring component 1 is positioned in the rotational direction.
　環状板部１ａの外周側には、電源リード線８の本数（３本）に対応する３つのリード線端末保持部１５が設けられている。また、環状板部１ａの外周側には、リード線端末保持部１５と組で芯線保持部２０が設けられている。芯線保持部２０は、リード線端末保持部１５から一定の距離を隔てて設けられている。 Three lead wire terminal holding portions 15 corresponding to the number (three) of power supply lead wires 8 are provided on the outer peripheral side of the annular plate portion 1a.

A pair of assembly legs 17a and 17b are provided, for example, and four protrusions 14 are provided, for example. The assembling feet 17a and 17b are provided on the inner peripheral side of the lead-out portion where the lead wire lead-out component 6 is attached to the lead wire wiring component 1. Since the assembly feet 17a and 17b have a thin-walled structure, the molding pressure received by the sensor substrate 11 during molding can be dispersed. Further, the protrusions 14 come into contact with the mold during molding, whereby the stator 10 is positioned in the axial direction.
　環状板部１ａの内周側には、電源リード線８をリード線口出し部品６からリード線端末保持部１５まで引回すための内壁１ｂが設けられている。リード線配線部品１に配線される電源リード線８の軸方向の位置ずれを防止するため、内壁１ｂには、径方向外側に向かって突出する位置ずれ防止用突起１９が設けられている（図２）。位置ずれ防止用突起１９により、電源リード線８の軸方向の位置決めがなされる。 An inner wall 1b for routing the power supply lead 8 from the lead wire lead-out component 6 to the lead wire terminal holding portion 15 is provided on the inner peripheral side of the annular plate portion 1a. In order to prevent the positional deviation in the axial direction of the power supply lead 8 wired to the lead wire wiring component 1, the inner wall 1b is provided with a positional deviation preventing projection 19 protruding outward in the radial direction (see FIG. 2). The misalignment prevention projection 19 positions the power supply lead 8 in the axial direction.
　３相の電源リード線８は、概略１２０°の間隔で固定子１０の周方向に配置された端子１２まで引回される。電源リード線８の端末は被覆が剥がされて芯線２１が現れ、芯線２１がリード線端末保持部１５の壁に当接されて位置決めがなされる。リード線端末保持部１５から引き出された電源リード線８の芯線２１は、芯線保持部２０まで引回される。芯線２１は、リード線配線部品１が固定子１０に組付けられた際に、芯線２１と端子１２とが互いに近接するように芯線保持部２０で保持される。 The three-phase power supply lead wires 8 are routed to the terminals 12 arranged in the circumferential direction of the stator 10 at intervals of approximately 120 °. The terminal of the power supply lead wire 8 is stripped and the core wire 21 appears, and the core wire 21 is brought into contact with the wall of the lead wire terminal holding portion 15 for positioning. The core wire 21 of the power supply lead wire 8 drawn from the lead wire terminal holding portion 15 is routed to the core wire holding portion 20. The core wire 21 is held by the core wire holding part 20 so that the core wire 21 and the terminal 12 are close to each other when the lead wire wiring component 1 is assembled to the stator 10.
　また、固定子１０にリード線配線部品１が組付けられ、芯線２１と端子１２とがスポット溶接される際に、端子１２と芯線２１とを挟み込む電極であるフック部８５の空間確保のために、環状板部１ａには、電極逃がし用の凹部１８が設けられている。そのため、電源リード線８は、環状板部１ａの固定子１０側の平坦面（リード線配線面）よりもさらに固定子１０側で引回され、凹部１８の両側に設けられた位置ずれ防止用突起１９によって軸方向の位置決めがなされる。 Further, when the lead wire wiring component 1 is assembled to the stator 10 and the core wire 21 and the terminal 12 are spot-welded, the space for the hook portion 85 that is an electrode for sandwiching the terminal 12 and the core wire 21 is secured. The annular plate portion 1a is provided with a recess 18 for electrode escape. Therefore, the power supply lead wire 8 is routed further on the stator 10 side than the flat surface (lead wire wiring surface) on the stator 10 side of the annular plate portion 1a, and is used for preventing misalignment provided on both sides of the recess 18. Positioning in the axial direction is performed by the protrusion 19.
　固定子１０にリード線配線部品１が組付けられる際、３相の電源リード線８は、内壁１ｂに沿ってリード線口出し部品６側に引回され、それぞれ折り返し部３７，３８，３９でリード線口出し部品６の方向に折り曲げられる（図２）。折り曲げられた電源リード線８は、リード線口出し部品６内で周方向に３相分設けられた電源リード線保持部（図示せず）に嵌め込まれることによって保持される。なお、折り返し部３７，３８，３９は、それぞれ電源リード線８の位置ずれを防止する突起３７ａ，３８ａ，３９ａを備えている。 When the lead wire wiring component 1 is assembled to the stator 10, the three-phase power supply lead wire 8 is routed to the lead wire lead-out component 6 side along the inner wall 1 b, and leads at the folded portions 37, 38, and 39, respectively. It is bent in the direction of the wire lead-out component 6 (FIG. 2). The bent power supply lead 8 is held by being fitted into a power supply lead holding part (not shown) provided for three phases in the circumferential direction in the lead wire lead-out component 6. The folded portions 37, 38, 39 are provided with protrusions 37 a, 38 a, 39 a that prevent displacement of the power supply lead 8, respectively.
　また、リード線口出し部品６内で周方向の中央の電源リード線保持部（図示せず）に保持される電源リード線８は、リード線口出し部品６から最も離れたリード線端末保持部１５まで引回される。また、リード線口出し部品６内で周方向の両側の電源リード線保持部（図示せず）にそれぞれ保持される電源リード線８は、リード線口出し部品６からそれぞれの側のリード線端末保持部１５まで引回される。ただし、これらの２本の電源リード線８のどちらか一方は、最も離れたリード線端末保持部１５まで配線される電源リード線８の径方向外側を引回される。 Further, the power supply lead 8 held by the power lead holding part (not shown) at the center in the circumferential direction in the lead wire lead part 6 extends to the lead terminal end holding part 15 farthest from the lead wire lead part 6. Be routed. Further, the power supply lead wires 8 respectively held by the power supply lead wire holding portions (not shown) on both sides in the circumferential direction in the lead wire lead-out component 6 are connected to the lead wire terminal holding portions on the respective sides from the lead wire lead-out component 6. Routed to 15. However, either one of the two power supply leads 8 is routed outside in the radial direction of the power supply lead 8 wired to the farthest lead wire terminal holding portion 15.
　リード線配線部品１は、リード線口出し部品６が取り付けられる外周側の部位、すなわち、リード線口出し部品６との対向部に、リード線ガイド２３を備える。リード線ガイド２３は、例えば平板状である。リード線ガイド２３は、リード線配線部品１上を引回されたセンサリード線７及び電源リード線８の軸方向の移動を抑制し、センサリード線７及び電源リード線８をリード線口出し部品６にガイドする。リード線ガイド２３には、リード線口出し部品６が着脱可能である。 The lead wire wiring component 1 includes a lead wire guide 23 at a portion on the outer peripheral side to which the lead wire lead-out component 6 is attached, that is, a portion facing the lead wire lead-out component 6. The lead wire guide 23 has a flat plate shape, for example. The lead wire guide 23 suppresses axial movement of the sensor lead wire 7 and the power supply lead wire 8 routed on the lead wire wiring component 1, and the sensor lead wire 7 and the power supply lead wire 8 are connected to the lead wire lead-out component 6. To guide. The lead wire lead-out component 6 can be attached to and detached from the lead wire guide 23.
　リード線口出し部品６は、板状の基部６ｊと、基部６ｊの両側に設けられた一対の係り止め部６ａ（第１の係り止め部）と、基部６ｊの両側に設けられた一対の係り止め部６ｂ（第２の係り止め部）と、基部６ｊと一体に形成され、基部６ｊからリード線配線部品１側に配置される板状部６ｅと、板状部６ｅの反固定子側の面上に設けられ、センサリード線７を保持するためのセンサリード線保持部６ｇを構成する複数の保持突起６ｈと、板状部６ｅの端部からリード線配線部品１側に突き出た複数の突起部２２とを備えている（図４）。 The lead wire lead-out component 6 includes a plate-like base portion 6j, a pair of locking portions 6a (first locking portions) provided on both sides of the base portion 6j, and a pair of locking pins provided on both sides of the base portion 6j. A portion 6b (second locking portion), a plate-like portion 6e formed integrally with the base portion 6j and disposed on the lead wiring component 1 side from the base portion 6j, and a surface of the plate-like portion 6e on the side opposite to the stator A plurality of holding projections 6h that are provided above and constitute a sensor lead wire holding portion 6g for holding the sensor lead wire 7, and a plurality of projections protruding from the end of the plate-like portion 6e toward the lead wire wiring component 1 side Part 22 (FIG. 4).
　基部６ｊは、反固定子側の面に、センサリード線７の本数（図示例では５本）と同数のセンサリード線配線用の溝６ｆを有し、固定子側の面に、電源リード線８の本数（３本）と同数の電源リード線配線用の溝（図示せず）を有する。保持突起６ｈの個数は、センサリード線７の本数よりも１つ少ない。板状部６ｅの固定子側の面上には、電源リード線８を保持するための電源リード線保持部（図示せず）を構成する複数の保持突起（図示せず）が設けられている。 The base 6j has the same number of sensor lead wire grooves 6f as the number of sensor lead wires 7 (five in the illustrated example) on the surface on the side opposite to the stator, and the power lead wire on the surface on the stator side. There are as many power supply lead wiring grooves (not shown) as eight (three). The number of holding protrusions 6h is one less than the number of sensor lead wires 7. A plurality of holding projections (not shown) constituting a power lead holding part (not shown) for holding the power lead 8 are provided on the surface of the plate-like part 6e on the stator side. .
　突起部２２は、リード線ガイド２３と対向して配置され、リード線口出し部品６から例えば径方向内側に向かって伸びている。突起部２２は、例えば、概略リード線ガイド２３の板厚の間隔で軸方向に配置された突起部２２ａ，２２ｂから成り、リード線ガイド２３の上下に分かれて二段に形成される。なお、突起部２２ａは、軸中心に向かって直線的に延伸し、突起部２２ｂは、一度軸方向に伸びた後に径方向に折れ曲がって軸中心に向かって直線的に延伸している。突起部２２ａは周方向に離隔した例えば２個から成る。突起部２２ｂも周方向に離隔した例えば２個から成る。 The protruding portion 22 is disposed to face the lead wire guide 23 and extends from the lead wire lead-out component 6 toward the inside in the radial direction, for example. The protrusion 22 includes, for example, protrusions 22 a and 22 b that are arranged in the axial direction at an interval of the thickness of the lead wire guide 23. The protrusion 22 is divided into two parts at the top and bottom of the lead wire guide 23. The protruding portion 22a extends linearly toward the axial center, and the protruding portion 22b extends once in the axial direction, then bends radially and extends linearly toward the axial center. The protrusion 22a is composed of, for example, two spaced apart in the circumferential direction. The protrusion 22b is also composed of, for example, two spaced apart in the circumferential direction.
　リード線口出し部品６は、突起部２２をリード線ガイド２３に嵌め合わせることにより、リード線配線部品１に組み付けることができる。すなわち、突起部２２ａ，２２ｂでリード線ガイド２３の両面を挟み込むようにして、突起部２２をリード線ガイド２３に嵌め合わせることにより、リード線口出し部品６をリード線配線部品１に組み付けることができる。また、リード線ガイド２３に嵌め合わされた突起部２２を径方向外側に引き抜くことで、リード線口出し部品６をリード線配線部品１から容易に取り外すことができる。 The lead wire lead-out component 6 can be assembled to the lead wire wiring component 1 by fitting the protrusion 22 to the lead wire guide 23. That is, the lead wire lead-out component 6 can be assembled to the lead wire wiring component 1 by fitting the protrusion 22 to the lead wire guide 23 so that both surfaces of the lead wire guide 23 are sandwiched between the protrusions 22a and 22b. . Further, the lead wire lead-out component 6 can be easily detached from the lead wire wiring component 1 by pulling out the protrusion 22 fitted to the lead wire guide 23 radially outward.
　リード線口出し部品６をリード線配線部品１に組み付け、リード線配線部品１とリード線口出し部品６とを一体に取り扱うことを可能とすることで、センサリード線７及び電源リード線８の配線を容易にすることができる。また、センサリード線７及び電源リード線８を組み付けた固定子１０を搬送する際に、センサリード線７及び電源リード線８に負荷がかかったとしてもリード線口出し部品６がリード線配線部品１に組み付けられているため、電源リード線８と固定子１０との接合部、あるいは、センサリード線７とセンサ基板１１との接合部に負荷がかかることがなく、組立の作業性が向上し、品質が向上する。なお、突起部２２は、リード線配線部品１から引き出されたセンサリード線７及び電源リード線８をリード線口出し部品６にガイドする機能も併せ持つ。 The lead wire lead component 6 is assembled to the lead wire lead component 1 so that the lead wire lead component 1 and the lead wire lead component 6 can be handled as a single unit so that the sensor lead wire 7 and the power supply lead wire 8 can be wired. Can be easily. Further, when the stator 10 assembled with the sensor lead wire 7 and the power supply lead wire 8 is transported, even if a load is applied to the sensor lead wire 7 and the power supply lead wire 8, the lead wire lead-out component 6 becomes the lead wire wiring component 1. Therefore, no load is applied to the joint between the power supply lead wire 8 and the stator 10 or the joint between the sensor lead wire 7 and the sensor substrate 11, and the assembly workability is improved. Quality is improved. The protrusion 22 also has a function of guiding the sensor lead wire 7 and the power supply lead wire 8 drawn from the lead wire wiring component 1 to the lead wire lead-out component 6.
　なお、本実施の形態では、リード線ガイド２３の上下に分かれた突起部２２ａ，２２ｂでリード線ガイド２３を挟み込むようにして、リード線口出し部品６をリード線配線部品１に組み付けたが、これに限らず、リード線口出し部品６をリード線配線部品１に着脱可能に組み付けることができれば他の構造でもよい。例えば、リード線ガイド２３に突起部２２が挿入可能な挿入孔を備えた部位を別途設けるようにし、突起部２２を挿入孔に挿入することでリード線口出し部品６をリード線配線部品１に組み付けることも可能である。また、突起部２２は、リード線配線部品１に向かう方向に伸びていればよく、例えば軸方向に伸びるようにしてもよく、いずれの場合も、リード線配線部品１に組付け可能であればよい。 In the present embodiment, the lead wire lead-out component 6 is assembled to the lead wire wiring component 1 so that the lead wire guide 23 is sandwiched between the projecting portions 22a and 22b divided above and below the lead wire guide 23. Not limited to this, other structures may be used as long as the lead wire lead-out component 6 can be detachably assembled to the lead wire wiring component 1. For example, the lead wire guide 23 is separately provided with an insertion hole into which the protrusion 22 can be inserted, and the lead wire lead-out component 6 is assembled to the lead wire wiring component 1 by inserting the protrusion 22 into the insertion hole. It is also possible. Further, the protruding portion 22 only needs to extend in a direction toward the lead wire wiring component 1, for example, may extend in the axial direction. In any case, the protrusion 22 can be attached to the lead wire wiring component 1. Good.
　また、突起部２２は、リード線ガイド６に係り止めされるフック部（図示せず）を備えていてもよい。例えば、突起部２２ｂの先端部を軸方向に突起部２２ａ側に僅かに伸びるようにＬ字型としてフック部（図示せず）を構成し、このフック部（図示せず）をリード線ガイド２３の軸中心側の端部に引っ掛けるようにすることができる。この場合、突起部２２ａの径方向の長さは少なくともリード線ガイド６の幅を要する。なお、フック部（図示せず）は、突起部２２ｂ、または、突起部２２ａ，２２ｂの双方に設けることもできる。また、リード線ガイド６にフック部（図示せず）を係り止める係止部（図示せず）を別途設けてもよい。突起部２２のフック部（図示せず）をリード線ガイド６に引っ掛けることにより、さらに強固にリード線口出し部品６とリード線配線部品１とを組み付けることが可能となる。 Further, the protrusion 22 may include a hook portion (not shown) that is engaged with the lead wire guide 6. For example, a hook portion (not shown) is formed in an L shape so that the tip end portion of the projection portion 22b extends slightly toward the projection portion 22a in the axial direction, and the hook portion (not shown) is used as the lead wire guide 23. It can be hooked on the end of the shaft center side. In this case, the length of the protrusion 22a in the radial direction requires at least the width of the lead wire guide 6. In addition, a hook part (not shown) can also be provided in both protrusion part 22b or protrusion part 22a, 22b. Further, a locking portion (not shown) for engaging the hook portion (not shown) with the lead wire guide 6 may be separately provided. By hooking the hook portion (not shown) of the protrusion 22 to the lead wire guide 6, the lead wire lead-out component 6 and the lead wire wiring component 1 can be more firmly assembled.
　係り止め部６ａは、基部６ｊの周方向側面から周方向に延びた後、径方向外側に屈曲するように形成されている。係り止め部６ａの先端部と基部６ｊとの間には、径方向外側に開口する開口部６ｄが形成される。開口部６ｄには、センサリード線保持部品５の足５ｂ（図６）が挿入される。すなわち、係り止め部６ａはセンサリード線保持部品５をリード線口出し部品６に組付ける際に使用され、センサリード線保持部品５の足５ｂを径方向内側に向かって係り止め部６ａに挿入することで、センサリード線保持部品５がリード線口出し部品６に組付けられる。 The anchoring portion 6a is formed so as to bend radially outward after extending in the circumferential direction from the circumferential side surface of the base portion 6j. An opening 6d that opens radially outward is formed between the distal end of the anchoring portion 6a and the base 6j. The foot 5b (FIG. 6) of the sensor lead wire holding component 5 is inserted into the opening 6d. That is, the latching portion 6a is used when the sensor lead wire holding component 5 is assembled to the lead wire lead-out component 6, and the legs 5b of the sensor lead wire holding component 5 are inserted into the latching portion 6a radially inward. Thus, the sensor lead wire holding component 5 is assembled to the lead wire lead-out component 6.
　係り止め部６ｂは、基部６ｊの周方向側面から径内側に延びている。係り止め部６ｂの先端部と基部６ｊとの間には、径方向内側に開口する開口部６ｃが形成される。開口部６ｃには、電源リード線保持部品４の足４ｂ（図６）が挿入される。すなわち、係り止め部６ｂは電源リード線保持部品４をリード線口出し部品６に組付ける際に使用され、電源リード線保持部品４の足４ｂを径方向外側に向かって係り止め部６ｂに挿入することで、電源リード線保持部品４がリード線口出し部品６に組付けられる。 The locking portion 6b extends radially inward from the circumferential side surface of the base portion 6j. An opening 6c that opens radially inward is formed between the distal end of the anchoring portion 6b and the base 6j. The foot 4b (FIG. 6) of the power supply lead wire holding component 4 is inserted into the opening 6c. That is, the locking portion 6b is used when the power supply lead wire holding component 4 is assembled to the lead wire lead-out component 6, and the foot 4b of the power supply lead wire holding component 4 is inserted into the locking portion 6b radially outward. Thus, the power supply lead wire holding component 4 is assembled to the lead wire lead-out component 6.
　電源リード線保持部品４は、リード線口出し部品６が設置される面から垂直方向に延びる一対の足４ｂと、足４ｂの先端部に設けられ、軸方向と直交する方向に伸びる突起４ｆとを備えている。 The power supply lead wire holding component 4 includes a pair of legs 4b extending in a vertical direction from a surface on which the lead wire lead-out component 6 is installed, and a protrusion 4f provided at the tip of the leg 4b and extending in a direction perpendicular to the axial direction. I have.
　リード線配線部品１に電源リード線８が配線された後、足４ｂをリード線口出し部品６の係り止め部６ｂに係止させることによって、電源リード線保持部品４がリード線口出し部品６に組付けられる。この際、電源リード線保持部品４は、突起４ｆにより、軸方向に位置決めがなされる。また、電源リード線保持部品４がリード線口出し部品６に係り止められた際に、電源リード線保持部品４に設けられたリブ４ｃがリード線口出し部品６に当接することにより、電源リード線８がリード線口出し部品６から表出する開口の大きさを抑えることができる。 After the power supply lead wire 8 is wired to the lead wire wiring component 1, the power lead wire holding component 4 is assembled to the lead wire lead-out component 6 by engaging the foot 4 b with the locking portion 6 b of the lead wire lead-out component 6. Attached. At this time, the power supply lead wire holding component 4 is positioned in the axial direction by the protrusion 4f. Further, when the power supply lead wire holding component 4 is engaged with the lead wire lead-out component 6, the rib 4 c provided on the power supply lead wire holding component 4 comes into contact with the lead wire lead-out component 6, whereby the power supply lead wire 8. However, the size of the opening exposed from the lead wire lead-out component 6 can be suppressed.
　センサリード線保持部品５は、リード線口出し部品６に係り止めされる足５ｂを備え、センサリード線７が引回された後に、径方向内側に向かってリード線口出し部品６に組付けられる。 The sensor lead wire holding component 5 includes a foot 5b that is engaged with the lead wire lead-out component 6, and is assembled to the lead wire lead-out component 6 radially inward after the sensor lead wire 7 is routed.
　センサ基板１１は、リード線配線部品１の組付け足１７ａ，１７ｂ及び突起１４により、リード線配線部品１に組付けられる。センサ基板１１がリード線配線部品１に組付けられた後、ボードインコネクタ８０が基板１１に半田付けされる。センサリード線７は、リード線配線部品１に電源リード線８が配線されている面とは反対側の面（リード線配線部品１の反固定子側面）に配線され、リード線口出し部品６に向って引回される。センサリード線７は、リード線口出し部品６の保持突起６ｈと電源リード線保持部品４の係り止め足４ｂとにより軽く保持される。 The sensor substrate 11 is assembled to the lead wire wiring component 1 by the assembly legs 17 a and 17 b and the protrusions 14 of the lead wire wiring component 1. After the sensor substrate 11 is assembled to the lead wire wiring component 1, the board-in connector 80 is soldered to the substrate 11. The sensor lead wire 7 is wired to the surface opposite to the surface where the power supply lead wire 8 is wired to the lead wire wiring component 1 (the side opposite to the stator of the lead wire wiring component 1), and is connected to the lead wire lead-out component 6. It is drawn around. The sensor lead wire 7 is held lightly by the holding protrusion 6 h of the lead wire lead-out component 6 and the locking foot 4 b of the power supply lead wire holding component 4.
　このように、電源リード線８がリード線配線部品１の固定子側面で引回され、センサリード線７がリード線配線部品１の反固定子側面で引回されることから、組立てが容易となりコストの低減が図れ、かつ、組立てが容易になることに伴い品質の向上が図れる。 Thus, since the power supply lead 8 is routed on the side surface of the stator of the lead wire wiring component 1 and the sensor lead wire 7 is routed on the side opposite to the stator of the lead wire wiring component 1, assembly is facilitated. Cost can be reduced and quality can be improved as assembly becomes easier.
　また、電源リード線８を環状板部１ａの複数の位置ずれ防止用突起１９で保持し、軸方向の位置ずれを防止することで、品質の向上が図れる。 Further, the power lead 8 is held by the plurality of misalignment prevention protrusions 19 of the annular plate portion 1a to prevent the misalignment in the axial direction, thereby improving the quality.
　また、リード線口出し部品６に２種類の係り止め部（係り止め部６ａ及び係り止め部６ｂ）を設けることで、センサリード線７はセンサリード線保持部品５で保持され、電源リード線８は電源リード線保持部品４で保持される。そのため、センサリード線７及び電源リード線８をそれぞれリード線口出し部品６に強固に組付けることが可能となり、信頼性の向上に伴う品質の向上が図れる。 Further, by providing the lead wire lead-out component 6 with two types of locking portions (the locking portion 6a and the locking portion 6b), the sensor lead wire 7 is held by the sensor lead wire holding component 5, and the power supply lead wire 8 is It is held by the power supply lead wire holding component 4. As a result, the sensor lead wire 7 and the power supply lead wire 8 can be firmly assembled to the lead wire lead-out component 6 respectively, and the quality can be improved as the reliability is improved.
　さらに、電源リード線保持部品４の足４ｂは、センサリード線７の保持にも使用されるため、組立てが容易となり、コストの低減が図れ、かつ、組立てが容易になることに伴い品質の向上が図れる。 Furthermore, since the foot 4b of the power supply lead wire holding component 4 is also used to hold the sensor lead wire 7, the assembly becomes easy, the cost can be reduced, and the quality improves as the assembly becomes easy. Can be planned.
　リード線配線部品１は、センサリード線７及び電源リード線８が配線された後、固定子１０に組付けられる。その際、取付け足１３の穴１３ａには固定子１０のピン８１が表出し、このピン８１が熱溶着、超音波溶着などされることで、リード線配線部品１が固定子１０に固定される。その後、芯線２１と端子１２とにスポット溶接が施され、電源リード線８と端子１２とが電気的に接続されて、固定子組立３０が得られる。 The lead wire wiring component 1 is assembled to the stator 10 after the sensor lead wire 7 and the power supply lead wire 8 are wired. At that time, the pin 81 of the stator 10 is exposed in the hole 13a of the mounting foot 13, and the lead wire wiring component 1 is fixed to the stator 10 by heat welding, ultrasonic welding or the like. . Thereafter, spot welding is performed on the core wire 21 and the terminal 12, and the power supply lead wire 8 and the terminal 12 are electrically connected to obtain the stator assembly 30.
　以上のようにセンサリード線７及び電源リード線８が組み付けられた固定子組立３０は、モールド成形時にモールド金型に設置する際に、リード線口出し部品６をリード線配線部品１から取り外して、ＢＭＣ（バルクモールディングコンパウンド）等の熱硬化性樹脂であるモールド樹脂で成形されて、モールド固定子が得られる。 The stator assembly 30 assembled with the sensor lead wire 7 and the power supply lead wire 8 as described above removes the lead wire lead-out component 6 from the lead wire wiring component 1 when it is installed in the mold during molding. A mold stator is obtained by molding with a mold resin which is a thermosetting resin such as BMC (bulk molding compound).
　固定子組立３０のモールド成形の際には、リード線口出し部品６は、中心から径方向外側に押し出されるため、固定子鉄心８２に接触することなく所定の位置を維持することが可能なため、センサリード線７同士あるいは電源リード線８同士の接触をリード線配線部品１に配線された状態以上に悪化させることなく、リード線口出し部品６とモールド樹脂との界面を伝わる水分の浸入を可能な限り抑制が可能なため、固定子１０の品質向上が可能となる。 When molding the stator assembly 30, the lead wire lead-out component 6 is pushed radially outward from the center, and therefore can maintain a predetermined position without contacting the stator core 82. Infiltration of moisture transmitted through the interface between the lead wire lead-out component 6 and the mold resin is possible without deteriorating the contact between the sensor lead wires 7 or between the power supply lead wires 8 more than the state of being wired to the lead wire wiring component 1. Since the suppression is possible as much as possible, the quality of the stator 10 can be improved.
　また、固定子１０を金型に設置した際、絶縁内壁８３ｂの反結線側に形成された突起（図示せず）は、金型に形成された設置部で支えられる。この設置部は、例えば、固定子鉄心８２の内径寸法より若干大きい外径の段付き部、金型芯金部の開口部設置面から固定子１０側に突状に延びる複数の爪、あるいは、金型芯金部の近傍のブラケット設置面から固定子鉄心８２の内径とは繋がらない状態で延びる複数の突起などである。 Further, when the stator 10 is installed in the mold, the protrusions (not shown) formed on the side opposite to the insulating inner wall 83b are supported by the installation section formed in the mold. This installation part is, for example, a stepped part having an outer diameter slightly larger than the inner diameter dimension of the stator core 82, a plurality of claws extending in a protruding manner from the opening part installation surface of the die core part to the stator 10 side, or A plurality of protrusions that extend from the bracket installation surface in the vicinity of the die core part and not connected to the inner diameter of the stator core 82.
　このように、固定子１０が金型の設置部で支えられるため、モールド成形時に固定子１０の外周部を金型（規制部材）で支える必要が無い。従って、モールド固定子の外郭には、固定子鉄心８２とモールド樹脂との間の境界面が形成されることがない。 Thus, since the stator 10 is supported by the installation part of the mold, it is not necessary to support the outer peripheral part of the stator 10 by the mold (regulating member) at the time of molding. Therefore, no boundary surface between the stator core 82 and the mold resin is formed on the outer periphery of the mold stator.

Needless to say, the method of manufacturing the motor includes a method of manufacturing the stator of the motor. With reference to FIG. 9, the manufacturing process of the electric motor according to the present embodiment will be described.
(1) Step 1: The stator core 82 is manufactured. In addition, a lead wire wiring assembly (sensor lead wire 7, power supply lead wire 8, and board-in connector 80) is manufactured. In addition, the lead wire wiring component 1 and the lead wire lead-out component 6 are manufactured.
(2) Step 2: A coil 84 is provided by winding around the stator core 82. At the same time, after the lead wire lead-out component 6 is assembled to the lead wire wiring component 1, the power supply lead wire 8 is wired to the lead wire wiring component 1. At this time, the core wire 21 of the power supply lead wire 8 is routed to the core wire holding portion 20. At the same time, the power supply lead wire holding component 4 is manufactured.
(3) Step 3: The power supply lead wire holding component 4 is assembled to the lead wire lead-out component 6. In addition, the sensor substrate 11 is manufactured.
(4) Step 4: Assemble the sensor substrate 11 to the lead wire wiring component 1. The terminals of the board-in connector 80 are soldered to the sensor substrate 11. In addition, the sensor lead wire holding component 5 is manufactured.
(5) Step 5: Assemble the sensor lead wire holding component 5 to the lead wire lead-out component 6.
(6) Step 6: The lead wire wiring component 1 is assembled to the stator 10, the pins 81 coming out from the mounting legs 13 of the lead wire wiring component 1 are thermally welded, and the terminals 12 and the core wire 21 are spot welded.
(7) Step 7: The lead wire lead-out component 6 is removed from the lead wire wiring component 1 when the stator assembly 30 is installed in the mold.
(8) Step 8: The stator assembly 30 is molded to produce a mold stator. In addition, parts such as rotors and brackets are manufactured.
(9) Step 9: An electric motor is manufactured by assembling a rotor or the like to the mold stator.
　以上説明したように、本実施の形態では、リード線配線部品１上を引回された電源リード線８及びセンサリード線７の軸方向の移動を抑制して電源リード線８及びセンサリード線７をリード線口出し部品６にガイドするリード線ガイド２３をリード線配線部品１に設けるとともに、リード線口出し部品６にはリード線ガイド２３に組み付けることが可能な突起部２２を設け、リード線口出し部品６をリード線配線部品１に着脱可能にしている。 As described above, in the present embodiment, the power supply lead wire 8 and the sensor lead wire 7 are restrained from moving in the axial direction of the power supply lead wire 8 and the sensor lead wire 7 routed on the lead wire wiring component 1. A lead wire guide 23 for guiding the lead wire lead part 6 is provided on the lead wire wiring part 1, and the lead wire lead part 6 is provided with a protrusion 22 that can be assembled to the lead wire guide 23. 6 is detachable from the lead wire wiring component 1.
　このような構成により、固定子組立３０をモールド金型に設置する際に、リード線口出し部品６をリード線配線部品１から取り外すことにより、モールド成形後のモールド樹脂部内ではリード線口出し部品６はリード線配線部品１から取り外された状態となり、リード線口出し部品６とモールド樹脂との界面を伝わる水分の浸入を可能な限り抑制が可能なため、固定子１０の品質向上が可能となる。 With such a configuration, when the stator assembly 30 is installed in a mold, the lead wire lead-out component 6 is removed from the lead wire lead-out component 1 so that the lead wire lead-out component 6 is formed in the mold resin portion after molding. Since the lead wire wiring component 1 is removed and the intrusion of moisture transmitted through the interface between the lead wire lead-out component 6 and the mold resin can be suppressed as much as possible, the quality of the stator 10 can be improved.
　また、電源リード線８及びセンサリード線７を組み付けた固定子１０を搬送する際に、電源リード線８及びセンサリード線７に負荷がかかったとしても、リード線口出し部品６がリード線配線部品１に組付けられて仮固定されているため、電源リード線８と固定子１０との接合部、あるいは、センサリード線７とセンサ基板１１との接合部に負荷がかかることがなく、組立の作業性が向上し、品質が向上する。 Further, even when a load is applied to the power supply lead wire 8 and the sensor lead wire 7 when the stator 10 assembled with the power supply lead wire 8 and the sensor lead wire 7 is conveyed, the lead wire lead-out component 6 becomes the lead wire wiring component. 1 and is temporarily fixed so that no load is applied to the joint between the power supply lead 8 and the stator 10 or the joint between the sensor lead 7 and the sensor substrate 11. Workability is improved and quality is improved.
　また、本実施の形態では、突起部２２はリード線口出し部品６から固定子１０の径方向内側に向かって伸びている。 Further, in the present embodiment, the protrusion 22 extends from the lead wire lead-out component 6 toward the radially inner side of the stator 10.
　このような構成により、固定子組立３０のモールド成形の際には、リード線口出し部品６は、モールド成形の圧力により中心から外側に押し出されるため、固定子鉄心８２に接触することなく、リード線口出し部品６の所定の位置を維持することが可能なため、リード線配線部品１とリード線口出し部品６とを確実に分離することが可能となる。 With such a configuration, when the stator assembly 30 is molded, the lead wire lead-out component 6 is pushed out from the center by the molding pressure, so that the lead wire is not in contact with the stator core 82. Since the predetermined position of the lead-out component 6 can be maintained, the lead wire wiring component 1 and the lead wire lead-out component 6 can be reliably separated.
　また、固定子組立３０のモールド成形の際には、リード線口出し部品６は、モールド成形の圧力により中心から外側に押し出されるため、人手をかけることなく、リード線口出し部品６とリード線配線部品１とを分離させることが可能となる。 In addition, when the stator assembly 30 is molded, the lead wire lead-out component 6 is pushed outward from the center by the molding pressure, so that the lead wire lead-out component 6 and the lead wire wiring component are not required manually. 1 can be separated.
　本実施の形態では、突起部２２は、概略リード線ガイド２３の板厚で軸方向に互いに離隔して配置された突起部２２ａ，２２ｂから成る。 In the present embodiment, the protrusion 22 is composed of protrusions 22 a and 22 b that are spaced apart from each other in the axial direction by the thickness of the lead wire guide 23.
　リード線口出し部品６の突起部２２ａ，２２ｂ間にリード線配線部品１のリード線ガイド２３を嵌め込むことにより、リード線口出し部品６を容易にリード線配線部品１に組み付けることが可能となる。 The lead wire lead-out component 6 can be easily assembled to the lead wire wiring component 1 by fitting the lead wire guide 23 of the lead wire wiring component 1 between the protrusions 22a, 22b of the lead wire lead-out component 6.
　また、リード線口出し部品６の突起部２２に、リード線配線部品１のリード線ガイド２３に係り止めするためのフック部（図示せず）を設けることができる。これにより、リード線口出し部品６を強固にリード線配線部品１に仮固定することが可能となる。 Further, a hook portion (not shown) for engaging with the lead wire guide 23 of the lead wire wiring component 1 can be provided on the protruding portion 22 of the lead wire lead-out component 6. Accordingly, the lead wire lead-out component 6 can be temporarily fixed to the lead wire wiring component 1 firmly.
　また、本実施の形態によれば、低コストで品質の良い固定子１０を用いることにより、電動機の品質向上を図ることができる。 Further, according to the present embodiment, the quality of the electric motor can be improved by using the stator 10 having a good quality at a low cost.
　また、固定子１０を備えた電動機を例えば、室外機の送風機に搭載することにより、空気調和機の品質向上を図ることができる。 Moreover, the quality improvement of an air conditioner can be aimed at by mounting the electric motor provided with the stator 10 in the air blower of an outdoor unit, for example.
　以上のように、本発明は、電動機の固定子、電動機、空気調和機、及び電動機の固定子の製造方法として有用である。 As described above, the present invention is useful as an electric motor stator, an electric motor, an air conditioner, and a method of manufacturing an electric motor stator.
