<< 1-1 >> Structure of Stator FIG. 1 is a perspective view showing a schematic structure of a stator 100 according to Embodiment 1 of the present invention. As shown in FIG. 1, three power supply lead wires (lead wires) 40 are connected to the stator 100. In addition, a lead wire wiring component 10 as a wiring component is assembled above the stator 100 (+ Z direction), and the power supply lead wire 40 is guided to the lead wire wiring component 10 through the lead-out component 30. In the following description, the upper side (+ Z direction) in FIG. 1 of the lead wire wiring component 10 is referred to as an anti-stator core side, and the lower side (−Z direction) is referred to as a stator core side.
　図１に示されるように、固定子１００は、固定子鉄心１と、絶縁部２と、巻線３と、端子４と、取付けピン５とを有する。固定子鉄心１は、積層された複数の電磁鋼板を有する。複数の電磁鋼板は、帯状に打ち抜かれた孔を有し、積層された複数の電磁鋼板は、かしめ、溶接、又は接着等で互いに固定される。絶縁部２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１と一体になるように成形することで、または、成形後に固定子に組付けることで、形成される。巻線３は、固定子１００のティースに施された絶縁部２にマグネットワイヤーが巻付けられてコイルを形成し、マグネットワイヤーの端末が端子４のフック部に引き回され、ヒュージング（熱かしめ）、あるいは、半田等で接合し、所定の方向に帯状のコアが曲げられて、突合せ部が溶接されることにより形成される。 As shown in FIG. 1, the stator 100 includes a stator core 1, an insulating portion 2, a winding 3, a terminal 4, and a mounting pin 5. The stator core 1 has a plurality of laminated magnetic steel sheets. The plurality of electromagnetic steel sheets have holes punched in a band shape, and the plurality of laminated electromagnetic steel sheets are fixed to each other by caulking, welding, adhesion, or the like. The insulating portion 2 is formed by molding a thermoplastic resin such as PBT (polybutylene terephthalate) or the like so as to be integrated with the stator core 1 or by assembling the stator with the stator after molding. In the winding 3, a magnet wire is wound around the insulating portion 2 applied to the teeth of the stator 100 to form a coil, and the end of the magnet wire is drawn around the hook portion of the terminal 4, so that fusing (heat caulking) is performed. ), Or by joining with solder or the like, the band-shaped core is bent in a predetermined direction, and the butt portion is welded.
　絶縁部２の外壁には、リード線配線部品１０を固定する複数の柱状（例えば、八角柱）の取付けピン５が複数箇所備えられている。取付けピン５がリード線配線部品１０の後述する挿入孔１１ａに挿入されることにより、リード線配線部品１０は固定子１００に対して固定される。また、固定子１００の内壁の－Ｚ方向側の端部には、固定子１００をモールド成形する際に、金型芯金部に固定子１００を設置して軸方向に当て止めされる内壁突起（図示しない）を備えている。内壁突起は、固定子１００の周方向に等間隔（ほぼ等間隔であればよい。）で設けられている。 The outer wall of the insulating part 2 is provided with a plurality of columnar (for example, octagonal column) mounting pins 5 for fixing the lead wire wiring component 10. The lead wire wiring component 10 is fixed to the stator 100 by inserting the mounting pin 5 into an insertion hole 11 a described later of the lead wire wiring component 10. Further, at the end of the inner wall of the stator 100 on the −Z direction side, when the stator 100 is molded, an inner wall protrusion that is fixed in the axial direction by installing the stator 100 on the metal core part. (Not shown). The inner wall projections are provided at regular intervals (substantially at regular intervals) in the circumferential direction of the stator 100.
　内壁突起は、その軸方向の高さが、絶縁部２の外壁の軸方向の高さ以下となるように形成することが望ましい。絶縁部２の外壁の軸方向の先端は、その高さが巻線３の軸方向における最大の高さよりも若干高くなるように形成されており、さらに巻線３は、その軸方向における高さが、絶縁部２の外壁から絶縁部２の内壁に向かうにつれて低くなるように形成される。そのため、内壁突起の軸方向の先端から巻線３までの距離が十分に確保される内壁突起の高さで、かつ、絶縁部２の外壁の高さ以下とする構成により、固定子１００の固定子鉄心側（－Ｚ方向側）を下にした状態で金型芯金部に固定子１００を設置したとき、金型芯金部に巻線３が当たることなく固定子１００を安定して置くことができる。コイルに電源を供給する電源リード線４０は、リード線配線部品１０により端子４まで引き回され、被覆を剥いて端子４とスポット溶接、あるいは、半田等で接合される。 The inner wall protrusion is preferably formed such that its axial height is equal to or less than the axial height of the outer wall of the insulating portion 2. The tip of the outer wall of the insulating portion 2 in the axial direction is formed such that its height is slightly higher than the maximum height in the axial direction of the winding 3, and the winding 3 is further increased in height in the axial direction. Is formed so as to become lower from the outer wall of the insulating portion 2 toward the inner wall of the insulating portion 2. For this reason, the stator 100 is fixed by a configuration in which the distance from the tip of the inner wall protrusion in the axial direction to the winding 3 is sufficiently high and the height of the outer wall of the insulating portion 2 is not more than the height. When the stator 100 is installed on the die core part with the core side (-Z direction side) down, the stator 100 is stably placed without the winding 3 hitting the mold core part. be able to. The power supply lead wire 40 that supplies power to the coil is routed to the terminal 4 by the lead wire wiring component 10, and the coating is peeled off and joined to the terminal 4 by spot welding or soldering.

FIG. 3 is an enlarged perspective view of the periphery of the wall surface portion 12 in FIG. As shown in FIG. 2, for example, an annular (doughnut type) lead wire wiring component 10 is used so that it can be assembled to the stator core 1. The lead wire wiring component 10 is manufactured by molding a thermoplastic resin such as PBT (Polybutylene terephthalate).

The terminal holding unit 15 and the positioning unit 16 are included.
　図２に示されるように、リード線配線部品１０の外周には、リード線配線部品１０を固定子１００へ組付ける際に使用される取付け足１１が複数箇所備えられている。固定子鉄心１にリード線配線部品１０が組付けられた際に、取付け足１１が絶縁部２の配線部品の設置面に当接して軸方向の位置決めがされる。取付け足１１には、固定子鉄心１の絶縁部２に備えられた取付けピン５を挿入する挿入孔１１ａが設けられ、絶縁部２の取付けピン５が取付け足１１の挿入孔１１ａに挿入されることで、リード線配線部品１０の回転方向の位置決めがなされる。絶縁部２の取付けピン５は、例えば、超音波溶着等により取付け足１１の挿入孔１１ａに挿入された状態で固定される。 As shown in FIG. 2, a plurality of mounting feet 11 used when the lead wire wiring component 10 is assembled to the stator 100 are provided on the outer periphery of the lead wire wiring component 10. When the lead wire wiring component 10 is assembled to the stator core 1, the mounting foot 11 comes into contact with the wiring component installation surface of the insulating portion 2 and is positioned in the axial direction. The mounting foot 11 is provided with an insertion hole 11 a for inserting the mounting pin 5 provided in the insulating portion 2 of the stator core 1, and the mounting pin 5 of the insulating portion 2 is inserted into the insertion hole 11 a of the mounting foot 11. As a result, the lead wire wiring component 10 is positioned in the rotational direction. The attachment pin 5 of the insulating part 2 is fixed in a state where it is inserted into the insertion hole 11a of the attachment foot 11 by, for example, ultrasonic welding or the like.
　図２及び図３に示されるようにリード線配線部品１０はリード線配線部品１０の外周から口出し部品３０に向かって径方向外向きに伸びた板状の部材である壁面部１２を備える。壁面部１２は壁面部１２の径方向端部から反固定子鉄心側に向けて突出した壁面部突起１２ａを備える。壁面部突起１２ａは、固定子１００のモールド成形時にモールド金型に当接する。壁面部１２は、口出し部品３０及び口出し部品３０に挿入される電源リード線４０に対して反固定子鉄心側（＋Ｚ方向側）に位置している。 2 and 3, the lead wire wiring component 10 includes a wall surface portion 12 that is a plate-like member extending radially outward from the outer periphery of the lead wire wiring component 10 toward the lead component 30. The wall surface portion 12 includes a wall surface portion protrusion 12 a that protrudes from the radial end portion of the wall surface portion 12 toward the anti-stator core side. The wall surface projections 12 a abut against the mold when the stator 100 is molded. The wall surface portion 12 is located on the anti-stator core side (+ Z direction side) with respect to the lead part 30 and the power supply lead wire 40 inserted into the lead part 30.
　図３に示されるように、リード線配線部品１０の壁面部１２の径方向外側には、口出し部品３０がリード線配線部品１０から間隔を空けて配置されている。口出し部品３０は、電源リード線４０を取りまとめ、口出しするための部品である。図３に示されるように、口出し部品３０は電源リード線４０を挿入するリード線挿入溝３１を３本備えている。また、口出し部品３０は電源リード線保持部品５０を保持する係り止め部３２を備えている。係り止め部３２は後述する電源リード線保持部品５０の足部５２と組み合うことにより、電源リード線保持部品５０を係り止める。図３に示されるように、口出し部品３０の径方向内側（－Ｙ方向側）の端面は、径方向外側に湾曲した湾曲部３３を備える。 As shown in FIG. 3, the lead-out component 30 is arranged at a distance from the lead wire wiring component 10 on the radially outer side of the wall surface portion 12 of the lead wire wiring component 10.

　以上に説明したように、実施の形態１に係る固定子１００によれば、以下のような効果を得ることができる。 << 1-2 >> Effects As described above, according to the stator 100 according to the first embodiment, the following effects can be obtained.
　実施の形態１に係る固定子１００によれば、口出し部品３０とリード線配線部品１０が間隔を空けて配置されるため、リード線配線部品１０と口出し部品３０との連結部分であって、水分の移動経路となっていた部分を取り除くことができ、口出し部品３０とモールド樹脂６０との境界部分又は電源リード線４０と口出し部品３０との境界部分から浸入した水分が、リード線配線部品１０と口出し部品３０との連結部分を伝わって固定子１００（固定子内部）に達することを防ぐことができる。したがって、固定子１００の性能の低下を防止することができ、品質が向上する。 According to the stator 100 according to the first embodiment, since the lead part 30 and the lead wire part 10 are arranged with a space therebetween, the lead part 30 and the lead part 30 are connected to each other. , The moisture that has entered from the boundary portion between the lead-out component 30 and the mold resin 60 or the boundary portion between the power supply lead wire 40 and the lead-out component 30 can be removed from the lead wire wiring component 10.

Therefore, the performance of the stator 100 can be prevented from being lowered, and the quality is improved.
　実施の形態１に係る固定子１００によれば、リード線配線部品１０は口出し部品３０に向かって伸びた壁面部１２を備えている。これにより、電源リード線４０が壁面部１２により覆われるため、製造工程において設備のエッジ部、治具などにより電源リード線４０が損傷することを抑制することができ、固定子１００の性能の低下を防止することができ、品質が向上する。 According to the stator 100 according to the first embodiment, the lead wire wiring component 10 includes the wall surface portion 12 extending toward the lead component 30. Thereby, since the power supply lead 40 is covered with the wall surface part 12, it can suppress that the power supply lead 40 is damaged by the edge part, jig | tool, etc. of an installation in a manufacturing process, and the performance of the stator 100 falls. Can prevent and improve the quality.
　実施の形態１に係る固定子１００によれば、壁面部１２は口出し部品３０及び口出し部品３０に挿入される電源リード線４０に対して反固定子鉄心側に位置している。これにより、固定子のモールド成形の際に電源リード線４０折り返し部周辺のＢＭＣ（不飽和ポリエステル）樹脂の流れが口出し部品３０側へと整流されるため、モールド金型の口出し部品３０の近傍に設けられた、エア抜き箇所に空気を送り込むことが可能となり、ボイドの発生が抑制でき、固定子１００の性能の低下を防止することができ、品質が向上する。 According to the stator 100 according to the first embodiment, the wall surface portion 12 is positioned on the side opposite to the stator core with respect to the lead part 30 and the power supply lead 40 inserted into the lead part 30. As a result, the flow of the BMC (unsaturated polyester) resin around the folded portion of the power supply lead wire 40 is rectified toward the lead-out component 30 when the stator is molded, so that it is near the lead-out component 30 of the mold. It becomes possible to send air to the provided air venting location, the generation of voids can be suppressed, the deterioration of the performance of the stator 100 can be prevented, and the quality is improved.
　実施の形態１に係る固定子１００によれば、壁面部１２と口出し部品３０の両末端の間には、略長穴形状の孔部２２が形成されている。これにより、固定子のモールド成形の際に折り返しピン１９周辺のＢＭＣ（不飽和ポリエステル）樹脂の流れがさらに口出し部品３０側へと整流されやすくなるため、モールド金型の口出し部品３０近傍に設けられた、エア抜き箇所に空気を送り込むことが可能となり、ボイドの発生が抑制でき、固定子１００の性能の低下を防止することができ、品質が向上する。 According to the stator 100 according to the first embodiment, the substantially elongated hole portion 22 is formed between the both ends of the wall surface portion 12 and the lead part 30. As a result, the flow of the BMC (unsaturated polyester) resin around the folding pin 19 is more easily rectified toward the lead-out component 30 when the stator is molded, so that the stator is provided near the lead-out component 30 of the mold. In addition, it becomes possible to send air into the air venting location, the generation of voids can be suppressed, the deterioration of the performance of the stator 100 can be prevented, and the quality is improved.
　実施の形態１に係る固定子１００によれば、リード線配線部品１０の壁面部１２は反固定子鉄心側の面に固定子の軸方向外側に突出した壁面部突起１２ａを備える。壁面部１２の壁面部突起１２ａがモールド成形時にモールド金型に当接することにより、モールド成形時の樹脂圧により壁面部１２が反固定子鉄心側に反ってしまうのを抑制することができ、固定子１００の性能の低下を防止することができ、品質が向上する。 According to the stator 100 according to the first embodiment, the wall surface portion 12 of the lead wire wiring component 10 includes the wall surface portion protrusion 12a that protrudes outward in the axial direction of the stator on the surface on the side opposite to the stator core. Since the wall surface protrusion 12a of the wall surface portion 12 abuts on the mold during molding, the wall surface portion 12 can be prevented from warping to the anti-stator core side due to the resin pressure during molding. A decrease in the performance of the child 100 can be prevented, and the quality is improved.

Therefore, it is not necessary to provide a protrusion or the like on the lead part 30. Therefore, the lead part 30 can be downsized.
　実施の形態１に係る固定子１００によれば、リード線配線部品１０に引き回された電源リード線４０は、リード線保持突起１７により保持される。これにより、引き回された電源リード線４０が口出し部品３０に向かってストレートに伸びるため、口出し部品３０と電源リード線保持部品５０の組付けの際に、電源リード線４０のクセによって電源リード線４０が電源リード線挿入溝５１に挿入されず組付けが困難となることを抑制でき、口出し部品３０と電源リード線保持部品５０との組付けが容易となる。 According to the stator 100 according to the first embodiment, the power supply lead wire 40 routed around the lead wire wiring component 10 is held by the lead wire holding protrusion 17. As a result, the routed power supply lead 40 extends straight toward the lead-out component 30, so that the power supply lead wire 40 may have a power lead when the lead-out component 30 and the power supply lead holding component 50 are assembled. 40 can be prevented from being inserted into the power supply lead wire insertion groove 51 and difficult to assemble, and the lead component 30 and the power supply lead wire holding component 50 can be easily assembled.
　実施の形態１に係る固定子１００によれば、リード線配線部品１０の壁面部１２の外径側の末端１２ｂは、前記口出し部品３０の内径側の末端３０ａと径方向同位置に位置する。これにより、リード線配線部品１０の上（反固定子鉄心側）から見た際に、電源リード線４０が壁面部１２により覆われ、電源リード線４０が表出することがないため、製造工程において設備のエッジ部、治具などにより電源リード線４０が損傷することを抑制することができ、固定子１００の性能の低下を防止することができ、品質が向上する。 According to the stator 100 according to the first embodiment, the outer end 12b of the wall surface portion 12 of the lead wire wiring component 10 is located at the same radial position as the inner end 30a of the lead-out component 30. Accordingly, when viewed from above the lead wire wiring component 10 (on the side opposite to the stator core), the power supply lead wire 40 is covered with the wall surface portion 12, and the power supply lead wire 40 is not exposed. In this case, it is possible to prevent the power supply lead wire 40 from being damaged by an edge portion of the equipment, a jig, or the like, to prevent the performance of the stator 100 from being deteriorated, and to improve the quality.
　実施の形態１に係る固定子１００によれば、リード線配線部品１０の壁面部１２の外径側の末端１２ｂは、口出し部品３０の内径側の末端３０ａに対して内径側に位置する構造としてもよい。これにより、リード線配線部品１０と口出し部の距離を確保することができ、固定子１００内部への水分の浸入を抑制することができ、固定子１００の性能の低下を防止することができ、品質が向上する。 According to the stator 100 according to the first embodiment, the outer end 12b of the wall surface portion 12 of the lead wire wiring component 10 is positioned on the inner diameter side with respect to the inner end 30a of the lead-out component 30.

　上記説明においては、リード線配線部品１０の位置決め部１６はリード線配線部品１０の本体に設けた例を説明したが、位置決め部１６はリード線配線部品１０と連結させた別部材としてもよい。位置決め部１６を別部材とする場合には、リード線配線部品１０本体と位置決め部１６との連結部分を薄肉連結形状とすることでモールド成形中の樹脂圧によって位置決め部１６が変形し、モールド樹脂の内径側に表出してしまうのを抑制することができる。 << 1-3 >> Modification of Embodiment 1 In the above description, the example in which the positioning portion 16 of the lead wire wiring component 10 is provided in the main body of the lead wire wiring component 10 has been described. A separate member connected to the component 10 may be used.
