Description

固定子、電動機および空気調和機Stator, electric motor and air conditioner
　本発明は、固定子、電動機、および空気調和機に関する。 The present invention relates to a stator, an electric motor, and an air conditioner.
　従来より空気調和機の室内機用または室外機用のファンモータにはモールド電動機が採用されている。このモールド電動機は固定子がモールド樹脂によりモールド成形されて外郭が形成され、その外殻の内側に回転子が配置されている。モールド電動機には配線基板に接続されたリード線を外部に引き出すための口出し部品であるリード線導出部が付けられている。リード線導出部は固定子と配線部品と共にモールド樹脂により一体成形されている。 Conventionally, a mold motor has been adopted as a fan motor for an indoor unit or an outdoor unit of an air conditioner. In this mold motor, a stator is molded with a mold resin to form an outer shell, and a rotor is disposed inside the outer shell. The mold motor is provided with a lead wire lead-out portion that is a lead-out component for drawing out the lead wire connected to the wiring board. The lead wire lead-out portion is integrally formed of a mold resin together with the stator and the wiring component.
　特許文献１に示す電動機は、位置検出用のセンサ回路が形成された基板と、固定子組立の軸方向の一端部に組付けられて口出し部を有するリード線配線部と、口出し部に組付けられ電源リード線を保持する電源リード線保持部品と、口出し部に組付けられセンサリード線を保持するセンサリード線保持部品とを備える。口出し部の一端側にはセンサリード線の挿入溝が形成され、口出し部の他端側には電源リード線の挿入溝が形成され、電源リード線とセンサリード線が口出し部の表裏から二段で外部に引き出される。 The electric motor shown in Patent Document 1 includes a substrate on which a sensor circuit for position detection is formed, a lead wire wiring portion that is assembled to one end portion in the axial direction of the stator assembly, and has a lead portion, and is assembled to the lead portion.

　ここでモールド電動機の種類には基板を搭載しない電動機と基板を搭載する電動機とがある。基板を搭載する電動機に利用されるリード線配線部が基板を搭載しない電動機に流用された場合、モールド成形時の樹脂が、口出し部に形成されたセンサリード線用の挿入溝から外部に漏れるという問題が生じる。そのため基板を搭載する電動機に利用されるリード線配線部は基板を搭載しない電動機に流用することができなかった。従って従来のモールド電動機は、固定子に基板を搭載する場合のリード線配線部と固定子に基板を搭載しない場合のリード線配線部とを異なる仕様にしており、成形樹脂部品の金型数の増加や、電動機の仕様変更に伴う部品点数の増大等による管理コストの増加が問題であった。 Here, there are two types of mold motors: a motor without a substrate and a motor with a substrate. When the lead wire wiring part used for the motor that mounts the board is diverted to the motor that does not mount the board, the resin at the time of molding leaks outside from the insertion groove for the sensor lead wire formed in the lead-out part. Problems arise. Therefore, the lead wire wiring part used for the motor on which the board is mounted cannot be diverted to the motor without the board. Therefore, the conventional mold motor has different specifications for the lead wire wiring portion when the substrate is mounted on the stator and the lead wire wiring portion when the substrate is not mounted on the stator, and the number of molds of the molded resin parts is different. The increase in management cost due to an increase in the number of parts accompanying the change in the motor specifications and the like was a problem.
　本発明は、上記に鑑みてなされたものであって、モールド成形時の樹脂漏れを防止するための電動機の仕様変更に伴うコストの増加を抑えることができる固定子を得ることを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to obtain a stator capable of suppressing an increase in cost associated with a change in the specification of an electric motor for preventing resin leakage during molding.
　上述した課題を解決し、目的を達成するために、本発明に係る固定子は、リード線が接続された固定子であって、固定子の外部にリード線を導くリード線導出部を備え、リード線導出部は、第１の板面と第２の板面を有する第１の板状部材と、第１の板面に対向する第３の板面と第４の板面を有する第２の板状部材と、第４の板面に対向する第５の板面と第６の板面を有する第３の板状部材とで構成され、第２の板状部材は、第１の板状部材と第３の板状部材とで挟まれ、第１の板面は、リード線を保持する第１の溝を有し、第３の板面は、リード線を保持する第２の溝を有し、第４の板面は、リード線を保持する第３の溝を有し、第５の板面は、第３の溝に嵌る形状の突部を有する。 In order to solve the above-described problems and achieve the object, the stator according to the present invention is a stator to which a lead wire is connected, and includes a lead wire lead-out portion that guides the lead wire to the outside of the stator, The lead wire lead-out portion includes a first plate member having a first plate surface and a second plate surface, a second plate surface having a third plate surface and a fourth plate surface opposite to the first plate surface. And a third plate member having a fifth plate surface and a sixth plate surface opposite to the fourth plate surface, and the second plate member is a first plate. The first plate surface has a first groove for holding the lead wire, and the third plate surface has a second groove for holding the lead wire. The fourth plate surface has a third groove for holding the lead wire, and the fifth plate surface has a protrusion shaped to fit into the third groove.
　この発明によれば、モールド成形時の樹脂漏れを防止するための電動機の仕様変更に伴うコストの増加を抑えることができる、という効果を奏する。 According to this invention, there is an effect that it is possible to suppress an increase in cost associated with a change in the specification of the electric motor for preventing resin leakage during molding.

Note that the present invention is not limited to the embodiments.
実施の形態１．
　図１は本発明の実施の形態１に係る電動機の固定子組立をリード線配線部側から見た斜視図である。固定子組立１００は、後述するモールド固定子と同軸となるように配置される環状の固定子２と、固定子２の軸方向の一端にて固定子２に組付けられた環状のリード線配線部１とを備える。固定子２は、帯状に打ち抜かれた複数の電磁鋼板をかしめ、溶接、または接着で軸方向に積層して成る固定子コア５と、熱可塑性樹脂により固定子コア５と一体に成形されまたは成形後に固定子コア５に組付けることで形成される絶縁部３と、絶縁部３にマグネットワイヤが巻回されて成る巻線４と、第１の端面２Ａと、第２の端面２Ｂとを有して構成されている。第１の端面２Ａは固定子コア５の端子２１を備える側の端面であり、第２の端面２Ｂはその反対側の端面である。 Embodiment 1 FIG.
1 is a perspective view of a stator assembly of an electric motor according to Embodiment 1 of the present invention as viewed from the lead wire wiring portion side. The stator assembly 100 includes an annular stator 2 disposed so as to be coaxial with a mold stator described later, and an annular lead wire that is assembled to the stator 2 at one end in the axial direction of the stator 2. Part 1. The stator 2 is formed integrally with the stator core 5 by caulking a plurality of electromagnetic steel plates punched in a strip shape and laminated in the axial direction by welding or adhesion, and the stator core 5 by a thermoplastic resin. An insulating portion 3 formed by later being assembled to the stator core 5, a winding 4 formed by winding a magnet wire around the insulating portion 3, a first end surface 2A, and a second end surface 2B are provided. Configured. The first end face 2A is an end face on the side provided with the terminals 21 of the stator core 5, and the second end face 2B is an end face on the opposite side.
　絶縁部３には、リード線配線部１側に突出してリード線配線部１を固定子コア５に取付けるための複数のピン２０と、外部からの電源が供給される複数の端子２１とが設けられている。マグネットワイヤの端末の一方は、端子２１のフック部２１ａに引回され、ヒュージングまたは半田で端子に接合される。マグネットワイヤの端末の他方は、全相の端末がまとめられて中性点を形成する。絶縁部３のピン２０を例えば超音波溶着または熱溶着することでリード線配線部１が固定子コア５が固定される。 The insulating portion 3 is provided with a plurality of pins 20 that protrude to the lead wire wiring portion 1 side and attach the lead wire wiring portion 1 to the stator core 5 and a plurality of terminals 21 to which power from the outside is supplied. It has been. One end of the magnet wire is drawn around the hook portion 21a of the terminal 21 and joined to the terminal by fusing or soldering. On the other end of the magnet wire, the terminals of all phases are combined to form a neutral point. The stator core 5 is fixed to the lead wire part 1 by, for example, ultrasonic welding or heat welding of the pins 20 of the insulating part 3.
　以下の説明では、固定子コア５の軸方向の端面外側、すなわち端子２１を備える側を結線側と称し、その反対側を反結線側と称する。 In the following description, the axial end face outside of the stator core 5, that is, the side provided with the terminal 21 is referred to as a connection side, and the opposite side is referred to as an anti-connection side.
　絶縁部３を構成する絶縁内壁３ｂは巻線４が固定子コア５の内側に倒れるのを防止する。絶縁内壁３ｂの反結線側の軸方向端部には、固定子組立１００をモールド成形する際、金型芯金部に対して軸方向に当て止めされる図示しない突起が設けられている。絶縁部３を構成する絶縁外壁３ａの軸方向端部の高さは、巻線４の軸方向における最大の高さよりも高くなるように形成されている。 The insulating inner wall 3b constituting the insulating portion 3 prevents the winding 4 from falling inside the stator core 5. A protrusion (not shown) is provided at the axial end of the insulating inner wall 3b on the side opposite to the connection side, and is fixed in the axial direction against the mold core when the stator assembly 100 is molded. The height of the end portion in the axial direction of the insulating outer wall 3a constituting the insulating portion 3 is formed to be higher than the maximum height in the axial direction of the winding 4.
　また、巻線４は、その軸方向における高さが、絶縁外壁３ａから絶縁内壁３ｂに向かうにつれて低くなるように形成されている。絶縁内壁３ｂの反結線側の突起の高さを、絶縁外壁３ａの軸方向端部の高さと同じにした場合、巻線４までの距離を十分に確保することができる。そのため、固定子２の反結線側を下にした状態で金型芯金部に固定子２を設置したとき、金型芯金部に巻線４が当たることなく固定子２を安定して置くことができる。その結果、生産性が向上すると共に品質も向上する。 The winding 4 is formed such that its axial height decreases as it goes from the insulating outer wall 3a toward the insulating inner wall 3b. When the height of the protrusion on the anti-connection side of the insulating inner wall 3b is the same as the height of the axial end of the insulating outer wall 3a, a sufficient distance to the winding 4 can be ensured. Therefore, when the stator 2 is installed on the die core with the anti-connection side of the stator 2 down, the stator 2 is stably placed without the winding 4 hitting the die core. be able to.

　第１の板状部材１１は、第２の板状部材１２との対向面である第１の板面に、電源リード線３０を保持する第１の溝１１ａを有する。 The first plate member 11 has a first groove 11 a that holds the power supply lead wire 30 on the first plate surface that is the surface facing the second plate member 12.
　第２の板状部材１２は、第１の板状部材１１の第１の板面との対向面である第３の板面１２ｆと、第３の板面１２ｆに形成され電源リード線３０を保持する第２の溝１２ａと、第３の板状部材１３の第５の板面との対向面である第４の板面１２ｇと、第４の板面１２ｇに形成される第３の溝１２ｂとを有する。第３の溝１２ｂは後述するようにセンサリード線を用いる場合においてセンサリード線を保持するための溝である。 The second plate-like member 12 is formed on the third plate surface 12f, which is a surface facing the first plate surface of the first plate-like member 11, and the third plate surface 12f. The second groove 12a to be held, the fourth plate surface 12g which is a surface facing the fifth plate surface of the third plate-like member 13, and the third groove formed on the fourth plate surface 12g 12b. The third groove 12b is a groove for holding the sensor lead wire when the sensor lead wire is used as will be described later.
　第１の溝１１ａ、第２の溝１２ａ、および第３の溝１２ｂの各々の数はリード線の本数に対応するものとする。すなわち第１の溝１１ａおよび第２の溝１２ａは電源リード線３０の本数に対応し、図示例のように３本のリード線群で構成される電源リード線３０を用いる場合には、第１の溝１１ａおよび第２の溝１２ａの各々は３つであり、３本のリード線群をシース被覆で１本にまとめた電源リード線３０を用いる場合には第１の溝１１ａおよび第２の溝１２ａの各々は１つである。 The number of each of the first groove 11a, the second groove 12a, and the third groove 12b corresponds to the number of lead wires. That is, the first groove 11a and the second groove 12a correspond to the number of the power supply lead wires 30, and when the power supply lead wire 30 composed of three lead wire groups is used as in the illustrated example, Each of the groove 11a and the second groove 12a is three, and when the power supply lead wire 30 in which three lead wire groups are combined into one by sheath coating is used, the first groove 11a and the second groove 12a Each of the grooves 12a is one.

Is used, the number of the third grooves 12b is one.
　第３の板状部材１３は、センサリード線を用いない場合に第２の板状部材１２に取付けられる。第３の板状部材１３は第３の溝１２ｂに嵌る形状の突部１３ｂを有する。突部１３ｂは第３の溝１２ｂの形状に沿った形状である。突部１３ｂの数は、第３の溝１２ｂと同様にリード線の本数に対応するものとする。 The third plate member 13 is attached to the second plate member 12 when the sensor lead wire is not used. The 3rd plate-shaped member 13 has the protrusion part 13b of the shape fitted to the 3rd groove | channel 12b. The protrusion 13b has a shape along the shape of the third groove 12b. The number of the protrusions 13b corresponds to the number of lead wires as in the third groove 12b.
　図１に示すリード線配線部１を基板非搭載仕様のリード線組立部品として使用する場合、第３の溝１２ｂには後述するセンサリード線が配線されないため、第３の溝１２ｂはモールド成形の際に樹脂が漏れる経路となりうる。 When the lead wire wiring portion 1 shown in FIG. 1 is used as a lead wire assembly part of a board non-mounting specification, since the sensor lead wire described later is not wired in the third groove 12b, the third groove 12b is formed by molding. This can be a path for resin to leak.
　図２に示す第３の板状部材１３を用いることにより、第３の溝１２ｂが突部１３ｂで封止され、モールド成形時に樹脂が漏れる経路を遮断することができる。また第３の板状部材１３を用いることにより、図１に示すリード線配線部１を基板非搭載仕様または基板搭載仕様のリード線組立部品として使用することができるため、仕様の異なるリード線配線部１を製造する必要がなく、成形樹脂部品の金型数、管理部品点数の削減により、製造コストや管理コストを削減することができる。 By using the third plate-like member 13 shown in FIG. 2, the third groove 12b is sealed by the protrusion 13b, and the path through which resin leaks during molding can be blocked. Further, by using the third plate-like member 13, the lead wire wiring portion 1 shown in FIG. 1 can be used as a lead wire assembly part of a board non-mounting specification or a board mounting specification. It is not necessary to manufacture the part 1, and the manufacturing cost and the management cost can be reduced by reducing the number of molds of the molded resin parts and the number of management parts.
　また第３の板状部材１３は、図１に示すリード線配線部１側の端部に封止部１３ａを備える。図２（Ｂ）に示す封止部１３ａは、第３の板状部材１３が第２の板状部材１２に組付けられた際、第２の板状部材１２のリード線配線部１側の端面に当接する。第３の溝１２ｂと突部１３ｂとの間に隙間が形成された場合、モールド成形時の樹脂圧によりこの隙間から樹脂が漏れる可能性がある。封止部１３ａが第２の板状部材１２のリード線配線部１側の端面に当接することにより、当該隙間から樹脂が漏れることを抑制することができ、更なる品質の向上が図れる。 Further, the third plate-like member 13 includes a sealing portion 13a at the end portion on the lead wire wiring portion 1 side shown in FIG. 2B, when the third plate-like member 13 is assembled to the second plate-like member 12, the sealing portion 13a on the lead wire wiring portion 1 side of the second plate-like member 12 Abuts against the end face. When a gap is formed between the third groove 12b and the protrusion 13b, the resin may leak from this gap due to resin pressure during molding. When the sealing portion 13a contacts the end surface of the second plate-like member 12 on the lead wire wiring portion 1 side, it is possible to prevent the resin from leaking from the gap and further improve the quality.
　図示例の封止部１３ａは長方形であるが、第３の溝１２ｂと突部１３ｂとの間の隙間を封止することができれば封止部１３ａの形状は長方形以外の形状、例えば櫛形状または円筒状でもよい。 The sealing portion 13a in the illustrated example is rectangular, but if the gap between the third groove 12b and the protrusion 13b can be sealed, the shape of the sealing portion 13a is a shape other than a rectangle, for example, a comb shape or It may be cylindrical.

　係り止め足１１ｂの端部には突起１１ｆが設けられている。リード線配線部１に電源リード線３０が配線された後、係り止め足１１ｂを第２の板状部材１２に係止させることによって、第１の板状部材１１が第２の板状部材１２に組付けられる。これにより部品外れを抑制することができ、また第２の板状部材１２への組付けが容易化され、コストの低減が図れる。また第２の板状部材１２への組付け容易化されることに伴い品質の向上が図れる。 A protrusion 11f is provided at the end of the anchoring foot 11b. After the power supply lead wire 30 is wired to the lead wire wiring portion 1, the locking plate 11 b is engaged with the second plate member 12, so that the first plate member 11 becomes the second plate member 12. Assembled to. As a result, component detachment can be suppressed, and the assembly to the second plate-like member 12 is facilitated, and the cost can be reduced. Further, the quality can be improved as the assembly to the second plate member 12 is facilitated.

FIG. 6 is a perspective view of the lead wire wiring portion of the electric motor according to Embodiment 1 of the present invention as viewed from the other end face side. FIG. 7 is a diagram illustrating a state where power supply lead wires are wired in the lead wire wiring portion of the electric motor according to Embodiment 1 of the present invention.
　リード線配線部１は、熱可塑性樹脂の一例であるＰＢＴ（Ｐｏｌｙ　Ｂｕｔｙｌｅｎｅ　Ｔｅｒｅｐｈｔｈａｌａｔｅ）を成形して形成される環状の配線部１ａと、配線部１ａの内側に形成される基板保持部１ｈと、リード線保持部１ｖを有して構成される。 The lead wire wiring portion 1 includes an annular wiring portion 1a formed by molding PBT (Poly Butylene Terephthalate) which is an example of a thermoplastic resin, a substrate holding portion 1h formed inside the wiring portion 1a, a lead It has a line holding part 1v.
　配線部１ａの外側には、複数の取付け足１ｂと、複数のリード線端末保持部１ｆと、芯線保持部１ｍとが形成されている。配線部１ａの内側には、基板保持部１ｈ、内壁１ｑ、および位置決め部１ｐが形成されている。図示例では４つの取付け足１ｂが形成されている。 A plurality of mounting legs 1b, a plurality of lead wire terminal holding portions 1f, and a core wire holding portion 1m are formed outside the wiring portion 1a. Inside the wiring part 1a, a substrate holding part 1h, an inner wall 1q, and a positioning part 1p are formed. In the illustrated example, four mounting legs 1b are formed.
　各取付け足１ｂは、図１の固定子２にリード線配線部１を組付ける際に使用される。各取付け足１ｂは、配線部１ａの外側に張り出し、図１の絶縁部３に設けられた端子２１を挿入するための穴１ｃを有する。リード線配線部１が固定子２に組付けられた際、取付け足１ｂが固定子２の絶縁部３の設置面に接することにより、リード線配線部１の軸方向の位置決めがなされる。また図１の絶縁部３のピン２０が、図５の取付け足１ｂの穴１ｃに挿入されることにより、リード線配線部１の回転方向の位置決めがなされる。 Each mounting foot 1b is used when the lead wire wiring portion 1 is assembled to the stator 2 in FIG. Each mounting foot 1b has a hole 1c for projecting outside the wiring portion 1a and for inserting a terminal 21 provided in the insulating portion 3 of FIG. When the lead wire wiring portion 1 is assembled to the stator 2, the mounting feet 1 b come into contact with the installation surface of the insulating portion 3 of the stator 2, whereby the lead wire wiring portion 1 is positioned in the axial direction. 1 is inserted into the hole 1c of the mounting foot 1b in FIG. 5, the lead wire wiring portion 1 is positioned in the rotational direction.
　図５の配線部１ａには、電源リード線３０の数に対応する複数のリード線端末保持部１ｆが形成されている。芯線保持部１ｍは、リード線端末保持部１ｆと組みで、リード線端末保持部１ｆから一定距離を隔てた位置に設けられている。 A plurality of lead wire terminal holding portions 1f corresponding to the number of power supply lead wires 30 are formed in the wiring portion 1a of FIG. The core wire holding part 1m is provided at a position spaced apart from the lead wire terminal holding part 1f by a combination with the lead wire terminal holding part 1f.
　配線部１ａの反固定子側には、台形状の複数の台座１ｒが形成されている。モールド成形の際、台座１ｒの端面が金型に接することにより、固定子組立１００の軸方向の位置決めが可能となる。台座１ｒを台形状にすることで、台座１ｒの端部が後述するモールド固定子の外部に表出する面積を少なくすることができ、また、台座１ｒの座屈強度を高めることもできる。 A plurality of trapezoidal pedestals 1r are formed on the anti-stator side of the wiring portion 1a. At the time of molding, the end surface of the base 1r is in contact with the mold, so that the stator assembly 100 can be positioned in the axial direction. By making the pedestal 1r into a trapezoidal shape, the area where the end of the pedestal 1r is exposed to the outside of the mold stator described later can be reduced, and the buckling strength of the pedestal 1r can be increased.
　基板保持部１ｈには、一対の組付け足１ｉと一対の溝１ｗと基板保持用の複数の突起１ｅが形成されている。組付け足１ｉは、後述するセンサ基板を配線部１ａに組付けるためのものである。図６に示すように組付け足１ｉの先端には爪１ｙが形成されている。組付け足１ｉは薄肉構造であるため、モールド成形時にセンサ基板が受ける成形圧力を分散させることができる。また、モールド成形時に突起１ｅが金型に当接することにより、センサ基板の軸方向への位置決めがなされ、センサ基板の軸方向へのずれが抑制される。 The substrate holding portion 1h is formed with a pair of assembly legs 1i, a pair of grooves 1w, and a plurality of protrusions 1e for holding the substrate. The assembly foot 1i is for assembling a sensor board, which will be described later, to the wiring portion 1a. As shown in FIG. 6, a claw 1y is formed at the tip of the assembly foot 1i. Since the assembly foot 1i has a thin structure, the molding pressure received by the sensor substrate during molding can be dispersed. Further, when the protrusion 1e contacts the mold during molding, the sensor substrate is positioned in the axial direction, and displacement of the sensor substrate in the axial direction is suppressed.
　また、センサ基板の切欠きが基板保持部１ｈの溝１ｗに嵌め込まれるため、成形圧力によるセンサ基板の移動または変形を抑制することが可能となり、電動機の品質の向上を図ることができる。またセンサ基板の面積を縮小した場合でもセンサ基板を配線部１ａへ容易に組付けることができるため、センサ基板の小型化に伴い電動機の固定子の低コスト化を図ることができる。 Further, since the notch of the sensor substrate is fitted into the groove 1w of the substrate holding portion 1h, it is possible to suppress the movement or deformation of the sensor substrate due to the molding pressure, and it is possible to improve the quality of the electric motor. Further, even when the area of the sensor board is reduced, the sensor board can be easily assembled to the wiring portion 1a, so that the cost of the stator of the motor can be reduced with the downsizing of the sensor board.
　内壁１ｑは、電源リード線３０をリード線保持部１ｖからリード線端末保持部１ｆまで引回すためのものである。図６に示すように内壁１ｑには、径方向外側に向けて突出する複数の突起１ｄが形成されている。各突起１ｄは、配線部１ａに配線される電源リード線３０の軸方向の位置ずれを防止するためのものである。 The inner wall 1q is for routing the power supply lead wire 30 from the lead wire holding portion 1v to the lead wire terminal holding portion 1f. As shown in FIG. 6, the inner wall 1q is formed with a plurality of protrusions 1d protruding outward in the radial direction. Each protrusion 1d is for preventing the axial displacement of the power supply lead wire 30 wired to the wiring portion 1a.
　配線部１ａには複数の凹部１ｊが形成されている。各凹部１ｊは、図１に示す固定子２の端子２１と電源リード線３０の芯線とを挟み込む電極であるフック部２１ａの空間を確保するためのものである。 A plurality of recesses 1j are formed in the wiring part 1a. Each recess 1j is for securing a space of a hook portion 21a that is an electrode for sandwiching the terminal 21 of the stator 2 and the core wire of the power supply lead wire 30 shown in FIG.
　第２の板状部材１２と第２の板状部材１２に隣接する取付け足１ｂとの間に、リード線配線部１の外側に壁部１ｘが形成される。壁部１ｘを設けることによりピンにリード線配線部１を溶着する際に溶けた樹脂がモールド固定子の外部に表出するのを抑制することができ、品質の向上が図れる。 A wall 1x is formed outside the lead wire wiring portion 1 between the second plate-like member 12 and the mounting leg 1b adjacent to the second plate-like member 12. By providing the wall portion 1x, it is possible to suppress the melted resin from being exposed to the outside of the mold stator when the lead wire wiring portion 1 is welded to the pin, and the quality can be improved.
　また、図１の固定子２のモールド成形の際、リード線導出部１０の周辺の樹脂の流れが整えられ、品質の向上が図れる。さらに壁部１ｘはリード線配線部１の組付け時に用いる治具の位置決めにも使用することができ、リード線配線部１の組付け作業性の向上が図れる。 Further, when the stator 2 of FIG. 1 is molded, the resin flow around the lead wire lead-out portion 10 is arranged, and the quality can be improved. Furthermore, the wall portion 1x can be used for positioning a jig used when the lead wire wiring portion 1 is assembled, and the workability of assembling the lead wire wiring portion 1 can be improved.
　第２の板状部材１２は、長方形板状の基部１２ｅと、第３の板状部材１３の係り止め足１３ｃに係止される一対の係り止め１２ｄと、第１の板状部材１１の突起１１ｆに係止される一対の係り止め１２ｃとを備える。第２の板状部材１２に図４の第３の板状部材１３を組付ける場合、第３の板状部材１３は、第３の板状部材１３の係り止め足１３ｃが固定子２の軸方向の結線側から反結線側へスライドするように、第２の板状部材１２の係り止め１２ｄに組付けられる。 The second plate-like member 12 includes a rectangular plate-like base portion 12e, a pair of latches 12d that are latched to the latching feet 13c of the third plate-like member 13, and a protrusion of the first plate-like member 11. And a pair of locking stoppers 12c locked to 11f. When the third plate member 13 of FIG. 4 is assembled to the second plate member 12, the third plate member 13 has a locking foot 13 c of the third plate member 13 that is the axis of the stator 2. The second plate-like member 12 is assembled to the latch 12d so as to slide from the direction connection side to the anti-connection side.
　また、第２の板状部材１２に図３の第１の板状部材１１を組付ける場合、第１の板状部材１１は、第１の板状部材１１の突起１１ｆがリード線配線部１の中心からリード線配線部１の径方向外側へ向かう方向にスライドするようにして、第２の板状部材１２の係り止め１２ｃに組付けられる。 When the first plate member 11 of FIG. 3 is assembled to the second plate member 12, the first plate member 11 has the protrusion 11 f of the first plate member 11 so that the lead wire wiring portion 1. The second plate-like member 12 is assembled to the latch 12c so as to slide in the direction from the center of the lead wire wiring portion 1 toward the radially outer side.
　このように第１の板状部材１１と第３の板状部材１３とが、異なる方向から第２の板状部材１２に組付けられるため、部品外れを抑制することができる。また第３の板状部材１３が固定子２の軸方向の結線側から反結線側へスライドするように第２の板状部材１２に組付けられるため、組付けが容易になり、コストの低減が図れるだけでなく、組立てが容易になることに伴い品質の向上が図れる。 Since the first plate-like member 11 and the third plate-like member 13 are assembled to the second plate-like member 12 from different directions as described above, it is possible to suppress part disengagement. Further, since the third plate-like member 13 is assembled to the second plate-like member 12 so as to slide from the axial connection side of the stator 2 to the anti-connection side, the assembly becomes easy and the cost is reduced. As well as being easy to assemble, quality can be improved.
　第２の板状部材１２の基部１２ｅには突起１２ｈが形成されている。突起１２ｈを設けることにより、第２の板状部材１２をリード線配線部１に向かって投影してなる領域の投影面積が増加し、モールド成形の際に第２の板状部材１２に加わる成形圧が増加し、半径方向に第２の板状部材１２が押し付けられ、第２の板状部材１２がモールド金型に当接して径方向の位置決めが可能となる。 A protrusion 12h is formed on the base 12e of the second plate member 12. By providing the projections 12h, the projected area of the region formed by projecting the second plate member 12 toward the lead wire wiring portion 1 is increased, and molding applied to the second plate member 12 during molding. The pressure increases, the second plate-like member 12 is pressed in the radial direction, and the second plate-like member 12 comes into contact with the mold and can be positioned in the radial direction.

The terminal of the power supply lead wire 30 is peeled off, and the terminal contacts the inside of the wall 1g of the lead wire terminal holding portion 1f, whereby the power supply lead wire 30 is positioned.
　リード線端末保持部１ｆから引き出された電源リード線３０の芯線３０ａは、芯線保持部１ｍまで引回される。リード線配線部１が図１の固定子２に組付けられた際、芯線３０ａは固定子２の端子２１と接するよう保持され、端子２１にスポット溶接される。 The core wire 30a of the power supply lead wire 30 drawn from the lead wire terminal holding portion 1f is routed to the core wire holding portion 1m. When the lead wire wiring portion 1 is assembled to the stator 2 of FIG. 1, the core wire 30 a is held so as to contact the terminal 21 of the stator 2 and is spot welded to the terminal 21.
　図６に示すようにリード線保持部１ｖには３つの折り返しピン１ｕが形成される。リード線配線部１が固定子２に組付けられた際、電源リード線３０は、図７に示すように内壁１ｑの径方向外側に沿ってリード線保持部１ｖまで引回される。３本の電源リード線３０の内、第２の板状部材１２から最も離れたリード線端末保持部１ｆに保持された電源リード線３０は、３つの折り返しピン１ｕの内、中央の折り返しピン１ｕまで引回される。 As shown in FIG. 6, three folding pins 1u are formed in the lead wire holding portion 1v. When the lead wire wiring portion 1 is assembled to the stator 2, the power supply lead wire 30 is routed to the lead wire holding portion 1v along the radially outer side of the inner wall 1q as shown in FIG. Of the three power supply lead wires 30, the power supply lead wire 30 held by the lead wire terminal holding portion 1f farthest from the second plate-like member 12 is the center return pin 1u among the three return pins 1u. To be routed to.
　３本の電源リード線３０の内、残りの２本の電源リード線３０は、３つの折り返しピン１ｕの内、両側の折り返しピン１ｕまで引回される。なお第２の板状部材１２から最も離れた位置に配線される電源リード線３０以外の２本のリード線の内、何れか一方は、最も離れた位置に配線される電源リード線３０の外側を引回される。 Of the three power supply leads 30, the remaining two power supply leads 30 are routed to the folding pins 1u on both sides of the three folding pins 1u. Note that one of the two lead wires other than the power supply lead wire 30 wired farthest from the second plate-shaped member 12 is outside the power lead wire 30 wired farthest away. Be routed.
　配線部１ａには凹部１ｊが設けられているため、電源リード線３０は、配線部１ａの固定子側の平坦な面よりもさらに固定子側で引回される。その際、内壁１ｑの突起１ｄによって電源リード線３０の軸方向の位置決めがなされる。リード線保持部１ｖまで引回された電源リード線３０は、リード線保持部１ｖの折り返しピン１ｕによって第２の板状部材１２側に折り曲げられる。 Since the wiring portion 1a is provided with the recess 1j, the power supply lead wire 30 is routed further on the stator side than the flat surface on the stator side of the wiring portion 1a. At that time, the power lead 30 is positioned in the axial direction by the projection 1d of the inner wall 1q. The power supply lead wire 30 routed to the lead wire holding portion 1v is bent to the second plate member 12 side by the folding pin 1u of the lead wire holding portion 1v.
　位置決め部１ｐは、配線部１ａの内壁１ｑの径方向内側に形成された基部１ｔと、基部１ｔに形成された挿入穴１ｓと、基部１ｔに形成された突起１ｎとを備える。挿入穴１ｓは、図１の固定子組立１００の回転方向の位置決めを行うためのものであり、固定子２の内径側面よりも内側に位置する。 The positioning portion 1p includes a base portion 1t formed on the inner side in the radial direction of the inner wall 1q of the wiring portion 1a, an insertion hole 1s formed in the base portion 1t, and a protrusion 1n formed in the base portion 1t. The insertion hole 1s is for positioning the stator assembly 100 in FIG. 1 in the rotational direction, and is located on the inner side of the inner diameter side surface of the stator 2.
　具体的には、挿入穴１ｓは、モールド金型の径方向の位置決めを行うためのセンターシャフトから突出するピンまたは突起に対応する位置に形成されている。センターシャフトから突出するピンまたは突起を挿入穴１ｓに挿入することによって、固定子組立１００の回転方向の位置決めがなされ、モールド金型に固定されるリード線導出部１０と固定子組立１００に接続されたリード線とが同一直線上に位置決めされる。 Specifically, the insertion hole 1s is formed at a position corresponding to a pin or protrusion protruding from the center shaft for positioning the mold in the radial direction. By inserting a pin or protrusion protruding from the center shaft into the insertion hole 1s, the stator assembly 100 is positioned in the rotational direction and connected to the lead wire lead-out portion 10 fixed to the mold and the stator assembly 100. The lead wire is positioned on the same straight line.
　同一直線上に位置決めされることで、固定子２が回転方向にずれた状態でモールド金型に挿入されることを防止でき、あるいは、リード線導出部１０と固定子２との角度のずれを防止することができる。従って、固定子組立１００に接続されたリード線が引っ張られて、後述するセンサ基板の半田部に負荷が加わることを抑制することができる。さらに、モールド成形時の樹脂圧により固定子２に回転方向の力が加わった際、回転止めの役割を果たすことができる。 By positioning on the same straight line, it is possible to prevent the stator 2 from being inserted into the mold in a state of being displaced in the rotational direction, or to prevent the angle deviation between the lead wire lead-out portion 10 and the stator 2. Can be prevented. Therefore, it is possible to prevent the lead wire connected to the stator assembly 100 from being pulled and a load from being applied to the solder portion of the sensor substrate described later. Furthermore, when a force in the rotational direction is applied to the stator 2 due to resin pressure during molding, it can serve as a rotation stopper.
　なお図５，６に示す基部１ｔは、配線部１ａの内壁１ｑの２カ所に連結された薄肉形状にすることで、モールド成形中の樹脂圧によって、位置決め部１ｐが変形するのを防止することができ、あるいは、モールド成形中の樹脂圧によって、位置決め部１ｐがモールド固定子６０の内径部側に表出するのを防止することができ、固定子２の品質の向上が図れる。 The base 1t shown in FIGS. 5 and 6 has a thin shape connected to two locations on the inner wall 1q of the wiring portion 1a, thereby preventing the positioning portion 1p from being deformed by the resin pressure during molding. Alternatively, it is possible to prevent the positioning portion 1p from being exposed to the inner diameter side of the mold stator 60 due to the resin pressure during molding, and the quality of the stator 2 can be improved.
　突起１ｎは、基部１ｔの固定子側面に形成され、モールド金型の半径方向の位置決めを行うセンターシャフトの軸方向端面に接するよう一定の高さに形成されている。突起１ｎを備えることで、モールド成形時に突起１ｎがセンターシャフトに接し、軸方向の位置決めがなされる。このことにより、モールド成形中の樹脂圧によって、位置決め部１ｐがモールド固定子６０の内径部側に表出するのを防止することができ、固定子２の品質の向上が図れる。 The protrusion 1n is formed on the side surface of the stator of the base 1t, and is formed at a certain height so as to contact the axial end surface of the center shaft that performs positioning in the radial direction of the mold. By providing the protrusion 1n, the protrusion 1n contacts the center shaft at the time of molding and positioning in the axial direction is performed. Thus, the positioning portion 1p can be prevented from being exposed to the inner diameter side of the mold stator 60 due to the resin pressure during molding, and the quality of the stator 2 can be improved.
　また位置決め部１ｐは、配線部１ａの内壁１ｑにおいて、リード線保持部１ｖと１８０度対向する位置に形成されている。このように構成した場合、例えば図１の固定子組立１００を用いたモールド電動機のシャフトが水平になるように室外機に設置し、さらにリード線保持部１ｖが下側であり位置決め部１ｐが上側となる位置関係にすることで、リード線導出部１０から水が浸入した場合でも、その水がセンサ基板に到達するのを抑制することができ、固定子２の品質の向上が図れる。 The positioning portion 1p is formed at a position facing the lead wire holding portion 1v at 180 degrees on the inner wall 1q of the wiring portion 1a. In such a configuration, for example, the shaft of the molded motor using the stator assembly 100 of FIG. 1 is installed in the outdoor unit so that the shaft is horizontal, the lead wire holding portion 1v is on the lower side, and the positioning portion 1p is on the upper side. With this positional relationship, even when water enters from the lead wire lead-out portion 10, the water can be prevented from reaching the sensor substrate, and the quality of the stator 2 can be improved.

　図８に示す基板搭載仕様のリード線配線部１では、基板保持部１ｈにセンサ基板６が組付けられている。また図８に示すリード線導出部１０では、第３の板状部材１３の代わりに第４の板状部材１４が用いられている。図示例のようにリード線配線部１にセンサ基板６を組付けた後、センサ基板とセンサリード線４０のボードイン形コネクタが半田で接合される。センサリード線４０は、リード線配線部１に電源リード線３０が配線された面の反対側面に引回される。 In the lead wire wiring part 1 of the board mounting specification shown in FIG. 8, the sensor board 6 is assembled to the board holding part 1h. Further, in the lead wire outlet 10 shown in FIG. 8, a fourth plate member 14 is used instead of the third plate member 13. After the sensor substrate 6 is assembled to the lead wire wiring portion 1 as in the illustrated example, the sensor substrate and the board-in connector of the sensor lead wire 40 are joined by soldering. The sensor lead wire 40 is routed to the side surface opposite to the surface where the power supply lead wire 30 is wired to the lead wire wiring portion 1.
　図９に示すセンサ基板６は、対角線上の角を面取りした長方形状であり、センサ基板６には、回転子の位置検出回路であるホールＩＣ７が実装されている。またセンサ基板６には、複数の端子挿入孔６ｄが形成されている。 The sensor substrate 6 shown in FIG. 9 has a rectangular shape with chamfered corners on a diagonal line, and a Hall IC 7 that is a rotor position detection circuit is mounted on the sensor substrate 6. The sensor board 6 has a plurality of terminal insertion holes 6d.
　各端子挿入孔６ｄは、センサリード線に設けられたボードイン形コネクタの端子を挿入するための穴である。端子挿入孔６ｄは、センサ基板６上の図示しない配線パターンと結ばれている。ボードイン形コネクタの端子が端子挿入孔６ｄに半田接合されることにより、後述するセンサリード線はセンサ基板６上の電子部品と電気的に接合される。 Each terminal insertion hole 6d is a hole for inserting a terminal of a board-in connector provided on the sensor lead wire. The terminal insertion hole 6d is connected to a wiring pattern (not shown) on the sensor substrate 6. A terminal of the board-in connector is soldered to the terminal insertion hole 6d, so that a sensor lead wire to be described later is electrically joined to an electronic component on the sensor substrate 6.
　センサ基板６の一方の長辺には、溝６ａと切欠き６ｂとが形成されている。溝６ａには、図８に示す基板保持部１ｈの組付け足１ｉが係り止めされる。切欠き６ｂは、基板保持部１ｈにセンサ基板６を組付けた際に位置決めとなる。センサ基板６の他方の長辺には、基板保持部１ｈにセンサ基板６を組付けた際に位置決めとなる２つの切欠き６ｃが形成されている。 A groove 6 a and a notch 6 b are formed on one long side of the sensor substrate 6. The assembly foot 1i of the substrate holding part 1h shown in FIG. 8 is latched to the groove 6a. The notch 6b is positioned when the sensor substrate 6 is assembled to the substrate holding part 1h. On the other long side of the sensor substrate 6, two notches 6c are formed for positioning when the sensor substrate 6 is assembled to the substrate holder 1h.
　図１０に示す第４の板状部材１４は、センサリード線が接する基部１４ｅと、基部１４ｅのセンサリード線接面に形成され第４の溝１４ｇと、一対の係り止め足１４ｃとを有する。係り止め足１４ｃは、基部１４ｅの側面から鉛直方向に延び、かつ、径方向内側に屈曲するＬ字状に形成されている。 The fourth plate member 14 shown in FIG. 10 has a base portion 14e with which the sensor lead wire contacts, a fourth groove 14g formed on the sensor lead wire contact surface of the base portion 14e, and a pair of locking feet 14c. The retaining foot 14c is formed in an L shape that extends in the vertical direction from the side surface of the base portion 14e and bends inward in the radial direction.
　係り止め足１４ｃは、図５に示す第２の板状部材１２の係り止め１２ｄと基部１２ｅとの間の開口部に挿入されて、係り止め１２ｄの端部に係止される。すなわち第２の板状部材１２に第４の板状部材１４を組付ける場合、第４の板状部材１４は、第４の板状部材１４の係り止め足１４ｃがリード線配線部１の径方向外側からリード線配線部１の中心へ向かう方向にスライドするようにして、第２の板状部材１２の係り止め１２ｄに組付けられる。 The locking foot 14c is inserted into an opening between the locking plate 12d and the base portion 12e of the second plate-like member 12 shown in FIG. 5, and is locked to the end of the locking plate 12d. That is, when the fourth plate member 14 is assembled to the second plate member 12, the fourth plate member 14 has the locking foot 14 c of the fourth plate member 14 having a diameter of the lead wire wiring portion 1. The second plate-like member 12 is assembled to the latch 12d so as to slide in the direction from the outside in the direction toward the center of the lead wire wiring portion 1.
　図８に示す基板搭載仕様のリード線配線部１では、第２の板状部材１２の一端面の他端面の各々に電源リード線３０とセンサリード線４０が配線される。そのため、組立てが容易となりコストの低減が図れ、また組立てが容易になることに伴い品質の向上が図れる。 8, the power supply lead wire 30 and the sensor lead wire 40 are wired on each of the other end surfaces of the one end surface of the second plate-like member 12. Therefore, the assembly is facilitated and the cost can be reduced, and the quality can be improved as the assembly is facilitated.
　また第２の板状部材１２は２種類の係り止め構造を有するため、電源リード線３０とセンサリード線４０の各々をリード線導出部１０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。さらに、第１の板状部材１１の係り止め足１１ｂを第４の板状部材１４の保持に利用することができ、組立てが容易となりコストの低減が図れ、組立てが容易になることに伴い品質の向上が図れる。 In addition, since the second plate-like member 12 has two types of locking structures, each of the power supply lead wire 30 and the sensor lead wire 40 can be firmly assembled to the lead wire lead-out portion 10 to improve reliability. Can improve quality. Furthermore, the locking foot 11b of the first plate-like member 11 can be used for holding the fourth plate-like member 14, and assembling becomes easy and costs can be reduced. Can be improved.
　図８に示すリード線配線部１は図７のリード線配線部１と同様に図１の絶縁部３のピン２０を例えば超音波溶着または熱溶着することで固定子コア５に固定される。 The lead wire wiring portion 1 shown in FIG. 8 is fixed to the stator core 5 by, for example, ultrasonic welding or heat welding of the pins 20 of the insulating portion 3 in FIG. 1 in the same manner as the lead wire wiring portion 1 in FIG.
　図１１は本発明の実施の形態１に係るモールド固定子の斜視図である。図１２は本発明の実施の形態１に係るモールド電動機の斜視図である。図１に示す固定子組立１００に熱硬化性樹脂の一例であるＢＭＣ（Ｂｕｌｋ　Ｍｏｌｄｉｎｇ　Ｃｏｍｐｏｕｎｄ）を成形することによりモールド固定子６０が得られる。モールド固定子６０の開口部には図示しない回転子とブラケット７４が組み込まれる。 FIG. 11 is a perspective view of the mold stator according to the first embodiment of the present invention. FIG. 12 is a perspective view of the molded electric motor according to Embodiment 1 of the present invention. A molded stator 60 is obtained by molding BMC (Bulk Molding Compound), which is an example of a thermosetting resin, in the stator assembly 100 shown in FIG. A rotor and a bracket 74 (not shown) are incorporated in the opening of the mold stator 60.
　またモールド固定子６０には、回転子のシャフト７２と防水キャップ７１とＥリング７３とが組付けられる。防水キャップ７１は、シャフト７２とブラケット７４との間からの水の浸入を防ぐためのものである。このことにより、生産性が良く、これに伴い品質が良く、かつ、コスト低減を図ることが可能なモールド電動機７０が得られる。 Further, a rotor shaft 72, a waterproof cap 71, and an E ring 73 are assembled to the mold stator 60. The waterproof cap 71 is for preventing water from entering between the shaft 72 and the bracket 74. As a result, a molded electric motor 70 is obtained that has good productivity, is accompanied by good quality, and can reduce costs.

　以上に説明したように本発明の実施の形態１に係る電動機によれば、リード線配線部１を基板非搭載仕様または基板搭載仕様のリード線組立部品として使用することができるため、仕様の異なるリード線配線部１を製造する必要がなく、成形樹脂部品の金型数の増加を抑えることができ、また仕様変更に伴うコストの増加を抑えることができる。 As described above, according to the electric motor according to the first embodiment of the present invention, the lead wire wiring portion 1 can be used as a lead wire assembly part of a board non-mounting specification or a board mounting specification, so that the specifications are different.

　別体リード線導出部品２２０は、一体リード線導出部品２１０に対向する第３の板面であるリード線当接面２２１と、リード線当接面２２１の反対側の第４の板面であるリード線非当接面２２２とを有する。リード線当接面２２１には、３つの円弧状の溝２２０ａと５つの円弧状の溝２２０ｂが並んで形成されている。 The separate lead wire lead-out component 220 is a lead wire contact surface 221 that is a third plate surface facing the integrated lead wire lead-out component 210, and a fourth plate surface opposite to the lead wire contact surface 221. And a lead wire non-contact surface 222. On the lead wire contact surface 221, three arc-shaped grooves 220a and five arc-shaped grooves 220b are formed side by side.
　３つの溝２２０ａの各々は、電源リード線用の挿通溝であり、３つの溝２２０ａの各々の幅は、電源リード線３０の外径よりも大きい。３つの溝２２０ａの各々には電源リード線３０が収められる。３つの溝２２０ａの各々の幅は、隣接する溝２２０ａの間の幅を表す。 Each of the three grooves 220 a is an insertion groove for a power supply lead wire, and the width of each of the three grooves 220 a is larger than the outer diameter of the power supply lead wire 30.

The sensor lead wire 40 is accommodated in each of the five grooves 220b. The width of each of the five grooves 220b represents the width between adjacent grooves 220b.
　別体リード線導出部品２２０の３つの溝２２０ａは、各々が一体リード線導出部品２１０の３つの溝２１０ａの各々と対向した位置に形成される。また別体リード線導出部品２２０の５つの溝２２０ｂは、各々が一体リード線導出部品２１０の５つの溝２１０ｂの各々と対向した位置に形成される。溝２１０ａと溝２２０ａとで囲われて構成された円筒状の空間には、電源リード線３０が挿通され保持されている。溝２１０ｂと溝２２０ｂとで囲われて構成された円筒状の空間には、センサリード線４０が挿通され保持されている。 The three grooves 220a of the separate lead wire lead-out component 220 are formed at positions facing each of the three grooves 210a of the integrated lead wire lead-out component 210, respectively.

　溝２１０ａの数および溝２２０ａの数は電源リード線３０の本数と等しく、溝２１０ｂの数および溝２２０ｂの数はセンサリード線４０の本数と等しい。なお、電源リード線３０の外径とセンサリード線４０の外径が等しい場合、リード線当接面２１１には、３つの溝２１０ａおよび５つの溝２１０ｂの代わりに、電源リード線３０の本数とセンサリード線４０の本数を合わせた数と等しい８つの溝２１０ａが形成され、または当該数と等しい８つの溝２１０ｂが形成される。 The number of grooves 210a and the number of grooves 220a are equal to the number of power supply lead wires 30, and the number of grooves 210b and the number of grooves 220b are equal to the number of sensor lead wires 40.

Alternatively, eight grooves 220b equal to the number are formed.
　次に、図１６および図１８を用いて、実施の形態２に係る電動機のリード線配線部１に、センサ基板６を取り付けない場合のリード線導出部２００の構成例を説明する。 Next, a configuration example of the lead wire deriving unit 200 when the sensor substrate 6 is not attached to the lead wire wiring unit 1 of the electric motor according to the second embodiment will be described with reference to FIGS. 16 and 18.
　図１６に示すように、リード線導出部２００を基板非搭載仕様のリード線組立部品として使用する場合、リード線配線部１にはセンサ基板６が取り付けられず、センサリード線は取り付けられていない。リード線導出部２００には電源リード線３０のみが挿通される。 As shown in FIG. 16, when the lead wire lead-out portion 200 is used as a lead wire assembly part of a board non-mounting specification, the sensor substrate 6 is not attached to the lead wire wiring portion 1 and the sensor lead wire is not attached. . Only the power supply lead wire 30 is inserted into the lead wire outlet 200.
　図１８に示すように、リード線導出部２００は、配線部１ａと一体で形成された第１の板状部材である一体リード線導出部品２１０と、配線部１ａと別体で形成され一体リード線導出部品２１０に重なって取り付けられる第２の板状部材である別体リード線導出部品２３０とで構成される。互いに重なり合った一体リード線導出部品２１０と別体リード線導出部品２３０とで挟まれた空間には、３本の電源リード線３０が挿通されている。 As shown in FIG. 18, the lead wire lead-out portion 200 is formed as a single body lead and lead component 210 that is a first plate-like member formed integrally with the wiring portion 1 a and the lead portion 1 a as a separate lead. It is comprised with the separate lead wire derivation | leading-out component 230 which is a 2nd plate-shaped member attached overlapping the wire derivation | leading-out component 210. FIG. Three power supply lead wires 30 are inserted in a space between the integrated lead wire lead-out component 210 and the separate lead wire lead-out component 230 that overlap each other.
　一体リード線導出部品２１０は、リード線導出部２００を基板搭載仕様のリード線組立部品として使用する場合と同一の形態である。別体リード線導出部品２３０は、一体リード線導出部品２１０に対向する第３の板面であるリード線当接面２３１と、リード線当接面２３１の反対側の第４の板面であるリード線非当接面２３２とを有する。 The integrated lead wire lead-out component 210 has the same form as when the lead wire lead-out portion 200 is used as a lead wire assembly component of board mounting specifications. The separate lead wire lead-out component 230 is a lead wire contact surface 231 that is a third plate surface facing the integrated lead wire lead-out component 210 and a fourth plate surface opposite to the lead wire contact surface 231. A lead wire non-contact surface 232.
　リード線当接面２３１には、３つの円弧状の溝２３０ａと５つの円弧状の突部２３０ｂとが並んで形成されている。 In the lead wire contact surface 231, three arc-shaped grooves 230a and five arc-shaped protrusions 230b are formed side by side.
　３つの溝２３０ａの各々は、電源リード線用の挿通溝であり、一体リード線導出部品２１０の３つの溝２１０ａの各々と対向した位置に形成されている。３つの溝２３０ａの各々の幅は、電源リード線３０の外径よりも大きい。３つの溝２３０ａの各々には、電源リード線３０が収められる。３つの溝２３０ａの各々の幅は、隣接する溝２３０ａの間の幅を表す。溝２１０ａと溝２３０ａとで囲われて構成された円筒状の空間には、電源リード線３０が挿通され保持されている。 Each of the three grooves 230 a is an insertion groove for a power supply lead wire, and is formed at a position facing each of the three grooves 210 a of the integrated lead wire lead-out component 210. The width of each of the three grooves 230 a is larger than the outer diameter of the power supply lead wire 30. The power supply lead wire 30 is accommodated in each of the three grooves 230a. The width of each of the three grooves 230a represents the width between adjacent grooves 230a. The power supply lead wire 30 is inserted and held in a cylindrical space surrounded by the groove 210a and the groove 230a.
　５つの突部２３０ｂの各々は、センサリード線用の挿通溝を埋める突部であり、一体リード線導出部品２１０の５つの溝２１０ｂの各々と対向した位置に形成されている。５つの突部２３０ｂの各々の幅は、一体リード線導出部品２１０の溝２１０ｂの幅と同等である。すなわち５つの突部２３０ｂの各々は、一体リード線導出部品２１０の溝２１０ｂに嵌まる形状であり、一体リード線導出部品２１０の溝２１０ｂを塞いでいる。これにより、モールド成形時に樹脂が漏れる経路を遮断している。 Each of the five protrusions 230b is a protrusion that fills the insertion groove for the sensor lead wire, and is formed at a position facing each of the five grooves 210b of the integrated lead wire lead-out component 210. The width of each of the five protrusions 230b is equal to the width of the groove 210b of the integrated lead wire outlet component 210. That is, each of the five protrusions 230 b has a shape that fits into the groove 210 b of the integrated lead wire outlet component 210 and closes the groove 210 b of the integrated lead wire outlet component 210. Thereby, the path | route which resin leaks at the time of mold shaping is interrupted | blocked.
　以上のように、実施の形態２に係るリード線導出部２００を基板非搭載仕様のリード線組立部品として使用する場合、リード線導出部２００に形成された溝にはセンサリード線４０が配線されず、リード線導出部２００内を貫通する円筒状の空間が形成されるため、モールド成形の際に樹脂が漏れる経路となりうる。実施の形態２では、突部２３０ｂを有する別体リード線導出部品２３０を用いることにより、円筒状の空間が突部２３０ｂで封止され、モールド成形時に樹脂が漏れる経路を遮断することができる。 As described above, when the lead wire lead-out portion 200 according to the second embodiment is used as a lead wire assembly part of a board non-mounting specification, the sensor lead wire 40 is wired in the groove formed in the lead wire lead-out portion 200. In addition, since a cylindrical space penetrating the inside of the lead wire outlet 200 is formed, it can be a path for resin to leak during molding. In the second embodiment, by using the separate lead wire lead-out component 230 having the protrusion 230b, the cylindrical space is sealed by the protrusion 230b, and the path through which resin leaks during molding can be blocked.
　従ってリード線配線部１を、基板非搭載仕様または基板搭載仕様のリード線組立部品として共用でき、仕様の異なるリード線配線部１を製造する必要がなく、成形樹脂部品の金型数、管理部品点数の削減により、製造コストや管理コストを削減することができる。また同一仕様のリード線配線部を使用することができるため、例えば基板非搭載仕様のリード線組立の製造工場が被災した場合の隘路対策となりうる。 Therefore, the lead wire wiring part 1 can be shared as a lead wire assembly part of a board non-mounting specification or a board mounting specification, and there is no need to manufacture the lead wire wiring part 1 having different specifications, the number of molds of molded resin parts, and management parts By reducing the number of points, manufacturing costs and management costs can be reduced. Moreover, since the lead wire wiring part of the same specification can be used, for example, it can be a countermeasure against a bottleneck when a manufacturing factory for a lead wire assembly of a board non-mounting specification is damaged.
　また実施の形態１に係るリード線導出部１０は、３つの板状部材で構成されていたが、実施の形態２に示すリード線導出部２００は２つの板状部材で構成でき、より少ない部材でリード線導出部を形成できるため、板状部材の金型の削減および板状部材の材料の削減ができ、さらなるコストの低減を実現できる。 In addition, the lead wire lead-out portion 10 according to the first embodiment is configured with three plate-like members, but the lead wire lead-out portion 200 illustrated in the second embodiment can be configured with two plate-like members, and fewer members. Since the lead wire lead-out portion can be formed, the number of plate-shaped members and the material of the plate-shaped members can be reduced, and further cost reduction can be realized.
　なお、実施の形態２では、溝２１０ａ、溝２２０ａ、および溝２３０ａの各々の幅は、電源リード線３０の外径よりも大きいが、電源リード線３０の外径よりも小さくし、または電源リード線３０の外径と同等にしてもよい。この場合、電源リード線３０は、その外径がつぶれるように溝２１０ａ、溝２２０ａ、および溝２３０ａに挿通される。 In the second embodiment, the width of each of the groove 210a, the groove 220a, and the groove 230a is larger than the outer diameter of the power supply lead wire 30, but smaller than the outer diameter of the power supply lead wire 30, or the power supply lead. The outer diameter of the wire 30 may be the same. In this case, the power supply lead wire 30 is inserted into the groove 210a, the groove 220a, and the groove 230a so that the outer diameter thereof is crushed.
　同様に、溝２１０ｂおよび溝２２０ｂの各々の幅は、センサリード線４０の外径よりも大きいが、センサリード線４０の外径よりも小さいし、またはセンサリード線４０の外径と同等にしてもよい。この場合、センサリード線４０は、その外径がつぶれるように溝２１０ｂおよび溝２２０ｂに挿通される。 Similarly, the width of each of the groove 210b and the groove 220b is larger than the outer diameter of the sensor lead wire 40, but smaller than the outer diameter of the sensor lead wire 40, or equal to the outer diameter of the sensor lead wire 40. Also good. In this case, the sensor lead wire 40 is inserted into the groove 210b and the groove 220b so that the outer diameter thereof is crushed.
　また、突部２３０ｂが溝２１０ｂを塞ぐ、または突部２３０ｂが溝２１０ｂに嵌まるとは、溝２１０ｂの幅と突部２３０ｂの外径が完全に一致する状態のみを示すわけではない。この「塞ぐ」または「嵌まる」という意味は、突部または溝の成形時の寸法誤差が生じても、モールド樹脂が漏れださない程度の多少の隙間が空いている場合も含む。 Further, the fact that the protrusion 230b closes the groove 210b or the protrusion 230b fits into the groove 210b does not indicate only a state in which the width of the groove 210b and the outer diameter of the protrusion 230b completely coincide with each other. The meaning of “closing” or “fitting” includes the case where there is a slight gap that does not allow the mold resin to leak out even if a dimensional error occurs when the protrusion or groove is formed.
　また、溝２１０ａ、溝２１０ｂ、溝２２０ａ、溝２２０ｂ、および溝２３０ａの各々の形状は、円弧状に限定されず、電源リード線３０またはセンサリード線４０が挿通できる形状であればよく、矩形状または三角形状といった凹状でも良い。突部２３０ｂの形状も同様に円弧状に限定されず、溝２１０ｂに嵌め合わされた際、モールド樹脂が漏れださない形状であればどのような形状であっても良い。 Further, the shape of each of the groove 210a, the groove 210b, the groove 220a, the groove 220b, and the groove 230a is not limited to an arc shape, and may be any shape as long as the power supply lead wire 30 or the sensor lead wire 40 can be inserted. Alternatively, a concave shape such as a triangular shape may be used. Similarly, the shape of the protrusion 230b is not limited to an arc shape, and may be any shape as long as the mold resin does not leak when fitted into the groove 210b.
　さらに溝２１０ａおよび溝２２０ａの各々の数は、電源リード線３０の本数と等しく、溝２１０ｂ、溝２２０ｂおよび突部２３０ｂの各々の数は、センサリード線４０の本数と等しい。前述した５本のセンサリード線群を用いる場合、溝２１０ｂ、溝２２０ｂおよび突部２３０ｂは各々５つであるが、例えば６本のセンサリード線群を用いる場合、溝２１０ｂ、溝２２０ｂおよび突部２３０ｂは各々６つとなる。この場合、６本のリード線群をシース被覆で１本にまとめたセンサリード線を用いる場合には溝２１０ｂ、溝２２０ｂおよび突部２３０ｂは各々が１つである。 Further, the number of each of the groove 210a and the groove 220a is equal to the number of the power supply lead wires 30, and the number of each of the groove 210b, the groove 220b and the protrusion 230b is equal to the number of the sensor lead wires 40. When the five sensor lead wire groups described above are used, there are five grooves 210b, 220b, and protrusions 230b. For example, when six sensor lead wire groups are used, the grooves 210b, grooves 220b, and protrusions are used. 230b is six each. In this case, when using a sensor lead wire in which six lead wire groups are combined into one by sheath coating, each of the groove 210b, the groove 220b, and the protrusion 230b is one.

In the third embodiment, a configuration example in which the lead wire insertion groove provided in the first plate-like member is provided as one is described.
　実施の形態３に係る電動機が実施の形態２に係る電動機と異なる点は、リード線配線部のリード線導出部の溝と突部の構成である。その他の構成は実施の形態２と同一または同等であり、実施の形態２と同一又は同等な構成部分は同一符号を付し、その説明を省略する。 The difference between the electric motor according to the third embodiment and the electric motor according to the second embodiment is the configuration of the grooves and protrusions of the lead wire lead-out portion of the lead wire wiring portion. Other configurations are the same as or equivalent to those of the second embodiment, and the same or equivalent components as those of the second embodiment are denoted by the same reference numerals and the description thereof is omitted.

When the sensor substrate 6 is attached to the lead wire wiring portion 1 shown in FIG. The shape differs depending on whether it is not installed.
　はじめに図１９を用いて、実施の形態３に係る電動機のリード線配線部１に、センサ基板６を取り付けた場合のリード線導出部３００の構成例を説明する。 First, a configuration example of the lead wire lead-out unit 300 when the sensor substrate 6 is attached to the lead wire wiring unit 1 of the electric motor according to Embodiment 3 will be described with reference to FIG.
　図１９に示すリード線導出部３００は、配線部１ａと一体で形成された第１の板状部材である一体リード線導出部品３１０と、配線部１ａと別体で形成され一体リード線導出部品３１０に重なって取り付けられる第２の板状部材である別体リード線導出部品３２０とで構成される。互いに重なり合った一体リード線導出部品３１０と別体リード線導出部品３２０とで挟まれた空間３４０には、３本の電源リード線３０および５本のセンサリード線４０が挿通されている。 A lead wire lead-out portion 300 shown in FIG. 19 is an integrated lead wire lead-out component 310 that is a first plate member formed integrally with the wiring portion 1a, and an integrated lead wire lead-out component formed separately from the wiring portion 1a. It is comprised with the separate lead wire derivation | leading-out component 320 which is a 2nd plate-shaped member attached so that it may overlap with 310. FIG. Three power supply lead wires 30 and five sensor lead wires 40 are inserted into a space 340 sandwiched between the integrated lead wire lead-out component 310 and the separate lead wire lead-out component 320 that overlap each other.
　一体リード線導出部品３１０は、別体リード線導出部品３２０に対向する第１の板面であるリード線当接面３１１と、リード線当接面３１１の反対側の第２の板面であるリード線非当接面３１２とを有する。リード線当接面３１１は矩形状の溝３１０ａを１つ有する。溝３１０ａは電源リード線およびセンサリード線用の挿通溝である。 The integrated lead wire lead-out component 310 is a lead wire contact surface 311 that is a first plate surface facing the separate lead wire lead-out component 320 and a second plate surface opposite to the lead wire contact surface 311. Lead wire non-contact surface 312. The lead wire contact surface 311 has one rectangular groove 310a. The groove 310a is an insertion groove for a power supply lead wire and a sensor lead wire.
　別体リード線導出部品３２０は、一体リード線導出部品３１０に対向する第３の板面であるリード線当接面３２１と、リード線当接面３２１の反対側の第４の板面であるリード線非当接面３２２とを有する。 The separate lead wire lead-out component 320 is a lead wire contact surface 321 that is a third plate surface facing the integrated lead wire lead-out component 310 and a fourth plate surface opposite to the lead wire contact surface 321. A lead wire non-contact surface 322.
　リード線当接面３２１には７つの矩形状の突部３２０ａが形成されている。７つの突部３２０ａの各々の高さは、溝３１０ａの深さと等しく、電源リード線３０の外径またはセンサリード線４０の外径よりも高い。また７つの突部３２０ａは一定の間隔Ａを空けて並んで形成されている。 Seven rectangular protrusions 320a are formed on the lead wire contact surface 321. The height of each of the seven protrusions 320 a is equal to the depth of the groove 310 a and is higher than the outer diameter of the power supply lead 30 or the sensor lead 40. Further, the seven protrusions 320a are formed side by side with a predetermined interval A therebetween.
　７つの矩形状の突部３２０ａが溝３１０ａに嵌め合わされることにより、別体リード線導出部品３２０のリード線当接面３２１と一体リード線導出部品３１０の溝３１０ａとの間の空間３４０には、３本の電源リード線３０および５本のセンサリード線４０が収められる。 By fitting the seven rectangular protrusions 320a into the groove 310a, the space 340 between the lead wire contact surface 321 of the separate lead wire lead-out component 320 and the groove 310a of the integrated lead wire lead-out component 310 is formed in the space 340. Three power supply lead wires 30 and five sensor lead wires 40 are accommodated.
　隣接する突部３２０ａの間には空間３００ａが形成される。６つの突部３２０ａの内、最も外側に設けられた２つの突部３２０ａの各々とリード線当接面３２１と溝３１０ａとに囲まれた部分には、空間３００ａが形成される。図１９に示すリード線導出部３００には、６つの空間３００ａと２つの空間３００ｂとが形成されている。 A space 300a is formed between adjacent protrusions 320a. Among the six protrusions 320a, a space 300a is formed in a portion surrounded by each of the two outermost protrusions 320a, the lead wire contact surface 321 and the groove 310a. In the lead wire outlet 300 shown in FIG. 19, six spaces 300a and two spaces 300b are formed.
　６つの空間３００ａの各々の幅は、電源リード線３０の外径またはセンサリード線４０の外径よりも広い。６つの空間３００ａの各々の高さは、溝３１０ａの深さと等しく、また電源リード線３０の外径またはセンサリード線４０の外径よりも高い。 The width of each of the six spaces 300a is wider than the outer diameter of the power supply lead wire 30 or the sensor lead wire 40. The height of each of the six spaces 300 a is equal to the depth of the groove 310 a and is higher than the outer diameter of the power supply lead 30 or the sensor lead 40.
　２つの空間３００ｂの各々の幅は、電源リード線３０の外径またはセンサリード線４０の外径よりも広い。２つの空間３００ｂの各々の高さは、溝３１０ａの深さと等しく、また電源リード線３０の外径またはセンサリード線４０の外径よりも高い。 The width of each of the two spaces 300b is wider than the outer diameter of the power supply lead wire 30 or the outer diameter of the sensor lead wire 40. The height of each of the two spaces 300b is equal to the depth of the groove 310a, and is higher than the outer diameter of the power supply lead 30 or the sensor lead 40.

The sensor lead wire 40 is housed in a space 300b on the right side of the paper surface of FIG. 19, and is further housed in a first, second, third, and fourth space 300a from the right side of the paper surface of FIG.
　次に図２０を用いて、実施の形態３に係る電動機のリード線配線部１に、センサ基板６を取り付ない場合のリード線導出部３００の構成例を説明する。 Next, a configuration example of the lead wire lead-out unit 300 when the sensor substrate 6 is not attached to the lead wire wiring unit 1 of the electric motor according to Embodiment 3 will be described with reference to FIG.
　図２０に示すリード線導出部３００は、配線部１ａと一体で形成された第１の板状部材である一体リード線導出部品３１０と、配線部１ａと別体で形成され一体リード線導出部品３１０に重なって取り付けられる第２の板状部材である別体リード線導出部品３３０とで構成される。互いに重なり合った一体リード線導出部品３１０と別体リード線導出部品３３０とで挟まれた空間３４０には、３本の電源リード線３０が挿通されている。 The lead wire lead-out portion 300 shown in FIG. 20 is an integrated lead wire lead-out component 310 that is a first plate member formed integrally with the wiring portion 1a, and an integrated lead wire lead-out component formed separately from the wiring portion 1a. It is comprised with the separate lead wire derivation | leading-out component 330 which is a 2nd plate-shaped member attached so that it may overlap with 310. FIG. Three power supply lead wires 30 are inserted into a space 340 sandwiched between the integrated lead wire lead-out component 310 and the separate lead wire lead-out component 330 that overlap each other.
　一体リード線導出部品３１０の構造は、一体リード線導出部品３１０と同一である。別体リード線導出部品３３０は、一体リード線導出部品３１０に対向する第３の板面であるリード線当接面３３１と、リード線当接面３３１の反対側の第４の板面であるリード線非当接面３３２とを有する。 The structure of the integrated lead wire deriving component 310 is the same as that of the integrated lead wire deriving component 310. The separate lead wire lead-out component 330 is a lead wire contact surface 331 that is a third plate surface facing the integrated lead wire lead-out component 310 and a fourth plate surface opposite to the lead wire contact surface 331. A lead wire non-contact surface 332.
　リード線当接面３３１には、２つの矩形状の突部３３０ａと、突部３３０ａよりも幅の広い１つの突部３３０ｂとが形成されている。２つの突部３３０ａの各々は、図１９に示す突部３２０ａと同様の形状であり、一定の間隔Ａを空けて並んで形成されている。また突部３３０ｂは突部３３０ａから一定の間隔Ａを空けて形成されている。 The lead wire contact surface 331 is formed with two rectangular protrusions 330a and one protrusion 330b wider than the protrusion 330a. Each of the two protrusions 330a has the same shape as the protrusion 320a shown in FIG. 19, and is formed side by side with a constant interval A therebetween. The protrusion 330b is formed with a certain distance A from the protrusion 330a.
　隣接する突部３３０ａの間には空間３００ａが形成される。突部３３０ａと突部３３０ｂとの間には空間３００ｂが形成される。２つ突部３３０ａの内、最も外側に設けられた突部３３０ａとリード線当接面３３１と溝３１０ａとに囲まれた部分には、空間３００ｃが形成される。すなわち図２０に示すリード線導出部３００には、３つの空間３００ａ，３００ｂ，３００ｃが形成されている。 A space 300a is formed between adjacent protrusions 330a. A space 300b is formed between the protrusion 330a and the protrusion 330b. A space 300c is formed in a portion surrounded by the outermost protrusion 330a, the lead wire contact surface 331, and the groove 310a among the two protrusions 330a. That is, three spaces 300a, 300b, and 300c are formed in the lead wire outlet 300 shown in FIG.
　３つの空間３００ａ，３００ｂ，３００ｃの各々の幅は、電源リード線３０の外径よりも広い。３つの空間３００ａ，３００ｂ，３００ｃの各々の高さは、溝３１０ａの深さと等しく、また電源リード線３０の外径よりも高い。そして、３つの空間３００ａ，３００ｂ，３００ｃの各々には、電源リード線３０が収められている。 The width of each of the three spaces 300a, 300b, and 300c is wider than the outer diameter of the power supply lead wire 30. The height of each of the three spaces 300a, 300b, and 300c is equal to the depth of the groove 310a and higher than the outer diameter of the power supply lead wire 30. A power supply lead wire 30 is housed in each of the three spaces 300a, 300b, and 300c.
　突部３３０ｂの幅は、５つ分の空間３００ａの幅と４つ分の突部３３０ａの幅とを足し合わせた幅に等しい。 The width of the protrusion 330b is equal to the sum of the width of the five spaces 300a and the width of the four protrusions 330a.
　このように一体リード線導出部品３１０には、電源リード線３０用の３つの空間３００ａ，３００ｂ，３００ｃと、電源リード線３０が挿通される３つの空間３００ａ，３００ｂ，３００ｃと、１つの突部３３０ｂとが形成される。一体リード線導出部品３１０は、突部３３０ｂにより、モールド成形時に樹脂が漏れる経路を遮断している。 Thus, the integrated lead wire lead-out component 310 has three spaces 300a, 300b, 300c for the power supply lead wire 30, three spaces 300a, 300b, 300c through which the power supply lead wire 30 is inserted, and one protrusion. 330b is formed. The integral lead wire lead-out component 310 blocks the path through which resin leaks during molding by the protrusion 330b.
　なお、実施の形態３では、溝３１０ａの深さと、突部３２０ａ、突部３３０ａおよび突部３３０ｂの高さと、間隔Ａの幅とが、電源リード線３０の外径またはセンサリード線４０の外径よりも深い。しかしながら、溝３１０ａの深さと、突部３２０ａ、突部３３０ａおよび突部３３０ｂの高さと、間隔Ａの幅とは、電源リード線３０の外径またはセンサリード線４０の外径よりも浅くてもよい。この場合、電源リード線３０またはセンサリード線４０は、その外径がつぶれるように３つの空間３００ａ，３００ｂ，３００ｃに挿通される。 In the third embodiment, the depth of the groove 310a, the height of the protrusions 320a, the protrusions 330a and the protrusions 330b, and the width of the interval A are determined by the outer diameter of the power supply lead wire 30 or the sensor lead wire 40. Deeper than the diameter. However, the depth of the groove 310a, the height of the protrusions 320a, the protrusions 330a and the protrusions 330b, and the width of the interval A may be shallower than the outer diameter of the power supply lead wire 30 or the sensor lead wire 40. Good. In this case, the power supply lead wire 30 or the sensor lead wire 40 is inserted into the three spaces 300a, 300b, and 300c so that the outer diameter thereof is crushed.
　以上のように、実施の形態３に係るリード線導出部３００を基板非搭載仕様のリード線組立部品として使用する場合、リード線導出部３００に形成された溝３１０ａにはセンサリード線４０が配線されず、リード線導出部３００内を貫通する円筒状の空間が形成され、モールド成形の際に樹脂が漏れる経路となりうる。実施の形態３では、一体リード線導出部品３１０に形成された溝３１０ａの一部に嵌る形状の突部３３０ｂが形成された別体リード線導出部品３３０を用いることにより、電源リード線３０が挿通される空間以外の空間が突部３３０ｂにより封止され、モールド成形時に樹脂が漏れる経路を遮断することができる。 As described above, when the lead wire lead-out part 300 according to the third embodiment is used as a lead wire assembly part of a board non-mounting specification, the sensor lead wire 40 is wired in the groove 310a formed in the lead wire lead-out part 300. Instead, a cylindrical space penetrating the lead wire lead-out portion 300 is formed, which can be a path for resin to leak during molding. In the third embodiment, the power supply lead wire 30 is inserted by using the separate lead wire lead-out component 330 formed with the protrusion 330b that fits in a part of the groove 310a formed in the integrated lead wire lead-out component 310. A space other than the space to be formed is sealed by the protrusion 330b, and a path through which resin leaks during molding can be blocked.
　従ってリード線配線部１を、基板非搭載仕様または基板搭載仕様のリード線組立部品として共用でき、仕様の異なるリード線配線部１を製造する必要がなく、成形樹脂部品の金型数、管理部品点数の削減により、製造コストや管理コストを削減することができる。また同一仕様のリード線配線部１を使用することができるため、例えば基板非搭載仕様のリード線組立の製造工場が被災した場合の隘路対策となりうる。 Therefore, the lead wire wiring part 1 can be shared as a lead wire assembly part of a board non-mounting specification or a board mounting specification, and there is no need to manufacture the lead wire wiring part 1 having different specifications, the number of molds of molded resin parts, and management parts By reducing the number of points, manufacturing costs and management costs can be reduced. Moreover, since the lead wire wiring part 1 of the same specification can be used, for example, it can be a countermeasure against a bottleneck when a manufacturing factory of a lead wire assembly not mounted on a board is damaged.
　また、実施の形態３に係るリード線導出部３００は、リード線導出部に形成させる溝を電源リード線３０およびセンサリード線４０の本数と同じにする必要がないため、リード線の本数が異なる電動機にもリード線配線部１を共用できる。従って共用するリード線配線部１をさらに増やすことができ、製造コストおよび管理コストをさらに削減をすることができる。 Further, the lead wire lead-out portion 300 according to the third embodiment does not need to have the same number of grooves formed in the lead wire lead-out portion as the number of the power supply lead wires 30 and the sensor lead wires 40, and therefore the number of lead wires is different. The lead wire wiring part 1 can also be shared by the electric motor. Therefore, the shared lead wire wiring part 1 can be further increased, and the manufacturing cost and the management cost can be further reduced.
　さらに実施の形態１に係るリード線導出部１０は、３つの板状部材で構成されていたが、実施の形態３に示すリード線導出部３００は２つの板状部材で構成でき、より少ない部材でリード線導出部１０を形成することができるため、板状部材の金型の削減および板状部材の材料の削減ができ、さらなるコストの低減を実現できる。 Furthermore, the lead wire lead-out portion 10 according to the first embodiment is configured with three plate-like members, but the lead wire lead-out portion 300 illustrated in the third embodiment can be configured with two plate-like members, and there are fewer members. Since the lead wire lead-out portion 10 can be formed, it is possible to reduce the mold of the plate-like member and the material of the plate-like member, thereby realizing further cost reduction.

　図２２は本発明の実施の形態４に係る電動機のリード線配線部を、基板非搭載仕様のリード線組立部品として使用する場合のリード線導出部を説明するための図である。実施の形態４に係る電動機のリード線配線部１にセンサ基板６を取り付けない場合、リード線導出部４００は、センサリード線４０が挿通されず、電源リード線３０のみが挿通される基板非搭載仕様のリード線組立部品として使用される。そしてリード線導出部４００には、新たな部品が追加される。 FIG. 22 is a view for explaining a lead wire lead-out portion when the lead wire wiring portion of the electric motor according to the fourth embodiment of the present invention is used as a lead wire assembly part of a board non-mounting specification. When the sensor substrate 6 is not attached to the lead wire wiring portion 1 of the electric motor according to the fourth embodiment, the lead wire lead-out portion 400 is not mounted on the substrate where the sensor lead wire 40 is not inserted and only the power supply lead wire 30 is inserted. Used as a lead wire assembly part for specifications. A new part is added to the lead wire lead-out unit 400.
　図２１に示すリード線導出部４００は、図２０に示すリード線導出部４００と同様に、リード線導出部４００は、一体リード線導出部品４１０と、別体リード線導出部品４２０と、別体リード線導出部品４３０で構成される。 The lead wire lead-out part 400 shown in FIG. 21 is similar to the lead wire lead-out part 400 shown in FIG. 20, and the lead wire lead-out part 400 includes an integrated lead wire lead-out part 410, a separate lead wire lead-out part 420, and a separate body. The lead wire lead-out component 430 is used.
　そして、一体リード線導出部品４１０の溝４１０ａと別体リード線導出部品４２０の溝４２０ａとで囲われて構成された電源リード線用の挿通空間である３つの円筒状の空間４００ａの各々には、電源リード線３０が挿通され保持されている。一方、一体リード線導出部品４１０の溝４１０ｂと別体リード線導出部品４３０の溝４３０ａとで囲われて構成されたセンサリード線用の挿通空間である５つの円筒状の空間４００ｂには、センサリード線４０の代わりに、５つの空間４００ｂの各々を塞ぐ円筒状の栓４４０が挿通されている。 Each of the three cylindrical spaces 400a, which is an insertion space for the power supply lead wire surrounded by the groove 410a of the integral lead wire lead-out component 410 and the groove 420a of the separate lead wire lead-out component 420, is included in each of the three cylindrical spaces 400a. The power supply lead wire 30 is inserted and held. On the other hand, the five cylindrical spaces 400b, which are insertion spaces for sensor lead wires, which are surrounded by the groove 410b of the integrated lead wire lead-out component 410 and the groove 430a of the separate lead wire lead-out component 430, Instead of the lead wire 40, a cylindrical plug 440 that closes each of the five spaces 400b is inserted.
　栓４４０は円筒状であり、栓４４０の直径は、一体リード線導出部品４１０の溝４１０ｂと別体リード線導出部品４３０の溝４３０ａとで囲われて構成された円筒状の空間４００ｂの内径と等しく、または、空間４００ｂの内径より大きい。 The plug 440 is cylindrical, and the diameter of the plug 440 is equal to the inner diameter of a cylindrical space 400b configured by being surrounded by the groove 410b of the integrated lead wire lead-out component 410 and the groove 430a of the separate lead wire lead-out component 430.

That is, five plugs 440 are packed. By using the plug 440, the cylindrical space 400b is sealed, and a path through which resin leaks during molding can be blocked.
　以上のように、実施の形態４に係るリード線導出部４００を基板非搭載仕様のリード線組立部品として使用する場合、溝４１０ｂ、溝４３０ａにはセンサリード線４０が配線されず、リード線導出部４００内を貫通する空間４００ｂが形成されるため、モールド成形の際に樹脂が漏れる経路となりうる。実施の形態４では、栓４４０を用いることにより、円筒状の空間４００ｂが栓４４０で封止され、モールド成形時に樹脂が漏れる経路を遮断することができる。 As described above, when the lead wire lead-out portion 400 according to the fourth embodiment is used as a lead wire assembly part of a board non-mounting specification, the sensor lead wire 40 is not wired in the groove 410b and the groove 430a, and the lead wire is led out. Since the space 400b penetrating through the portion 400 is formed, it can be a path through which resin leaks during molding. In the fourth embodiment, by using the plug 440, the cylindrical space 400b is sealed with the plug 440, and a path through which resin leaks during molding can be blocked.
　従ってリード線配線部１を、基板非搭載仕様または基板搭載仕様のリード線組立部品として共用でき、仕様の異なるリード線配線部１を製造する必要がなく、成形樹脂部品の金型数、管理部品点数の削減により、製造コストや管理コストを削減することができる。また同一仕様のリード線配線部１を使用することができるため、例えば基板非搭載仕様のリード線組立の製造工場が被災した場合の隘路対策となりうる。 Therefore, the lead wire wiring part 1 can be shared as a lead wire assembly part of a board non-mounting specification or a board mounting specification, and there is no need to manufacture the lead wire wiring part 1 having different specifications, the number of molds of molded resin parts, and management parts By reducing the number of points, manufacturing costs and management costs can be reduced. Moreover, since the lead wire wiring part 1 of the same specification can be used, for example, it can be a countermeasure against a bottleneck when a manufacturing factory of a lead wire assembly not mounted on a board is damaged.
　またリード線導出部４００の外郭を構成する第１の板状部材、第２の板状部材および第３の板状部材よりも体積の小さな栓の金型を使用すればよいため、金型の小型化により、製造コスト、管理コストおよび材料コストをさらに抑えることができる。 In addition, since it is only necessary to use a plug mold having a smaller volume than the first plate-shaped member, the second plate-shaped member, and the third plate-shaped member constituting the outline of the lead wire lead-out portion 400, By downsizing, manufacturing cost, management cost and material cost can be further suppressed.
　なお、実施の形態４では、溝４１０ａおよび溝４２０ａの幅が電源リード線３０の外径よりも大きい。しかしながら、溝４１０ａおよび溝４２０ａの幅は、電源リード線３０の外径よりも小さくてもよいし、電源リード線３０の外径と同等でもよい。この場合、電源リード線３０は、その外径がつぶれるように溝４１０ａおよび溝４２０ａに挿通される。 In the fourth embodiment, the width of the groove 410 a and the groove 420 a is larger than the outer diameter of the power supply lead wire 30. However, the widths of the grooves 410 a and 420 a may be smaller than the outer diameter of the power supply lead wire 30 or may be equal to the outer diameter of the power supply lead wire 30. In this case, the power supply lead wire 30 is inserted into the groove 410a and the groove 420a so that the outer diameter thereof is crushed.
　同様に、実施の形態４では、溝４１０ｂおよび溝４３０ａの幅は、センサリード線４０の外径よりも大きい。しかしながら、溝４１０ｂおよび溝４３０ａの幅は、センサリード線４０の外径よりも小さくてもよいし、センサリード線４０の外径と同等でもよい。この場合、センサリード線４０は、その外径がつぶれるように溝４１０ｂおよび溝４３０ａに挿通される。 Similarly, in the fourth embodiment, the width of the groove 410b and the groove 430a is larger than the outer diameter of the sensor lead wire 40. However, the width of the groove 410b and the groove 430a may be smaller than the outer diameter of the sensor lead wire 40 or may be equal to the outer diameter of the sensor lead wire 40. In this case, the sensor lead wire 40 is inserted into the groove 410b and the groove 430a so that the outer diameter thereof is crushed.
　また、栓４４０が空間４００ｂを塞ぐとは、空間４００ｂの内径と栓４４０の外径が完全に一致する状態のみを示すわけではない。この「塞ぐ」という意味は、栓４４０または溝４２０ａの成形時の寸法誤差が生じても、モールド樹脂が漏れださない程度の多少の隙間が空いている場合も含む。 In addition, the fact that the plug 440 blocks the space 400b does not indicate only a state where the inner diameter of the space 400b and the outer diameter of the plug 440 completely coincide with each other. The meaning of “closing” includes a case where there is a slight gap that does not allow the mold resin to leak even if a dimensional error occurs when the plug 440 or the groove 420a is molded.
　また、溝４１０ａ、溝４１０ｂ、溝４２０ａ、および溝４３０ａの各々の形状は、円弧状に限定されず、電源リード線３０またはセンサリード線４０が挿通できる形状であればよく、矩形状または三角形状といった凹状でも良い。栓４４０の形状も円筒状に限定されず、空間４００ｂに嵌め合わされた際、モールド樹脂が漏れださない形状であればどのような形状であっても良い。 The shape of each of the groove 410a, the groove 410b, the groove 420a, and the groove 430a is not limited to the arc shape, and may be any shape that allows the power supply lead wire 30 or the sensor lead wire 40 to be inserted, and may be rectangular or triangular. It may be concave. The shape of the plug 440 is not limited to a cylindrical shape, and may be any shape as long as the mold resin does not leak when fitted into the space 400b.
　また、実施の形態４では、空間４００ｂを塞ぐ栓４４０が円筒状である例を示したが、栓４４０の代わりに、５つの空間４００ｂの各々に嵌まる形状の５つの円筒状部材と、栓部材とを用いてもよい。この栓部材は、５つの円筒状部材の各々の一端を固定し、または５つの円筒状部材の各々の一端に一体に形成される部材である。このように５つの栓４４０を一つの部材として構成しても良い。栓４４０を一つの部材にすることで５つの空間４００ｂを一度に塞ぐことができる。そのため、５つの空間４００ｂの各々を栓４４０の塞ぐ場合に比べて、組み立て時間が短縮され製造コストを抑えることができる。 In the fourth embodiment, the plug 440 that closes the space 400b is cylindrical. However, instead of the plug 440, five cylindrical members that fit in the five spaces 400b, and the plug You may use a member. The plug member is a member that fixes one end of each of the five cylindrical members or is integrally formed at one end of each of the five cylindrical members. Thus, you may comprise the five stoppers 440 as one member. By using the plug 440 as one member, the five spaces 400b can be closed at once. Therefore, as compared with the case where each of the five spaces 400b is closed by the plug 440, the assembly time is shortened and the manufacturing cost can be suppressed.
　また実施の形態４では、実施の形態１に係るリード線導出部１０と同様の形状のリード線導出部４００に形成された空間４００ｂを栓４４０で塞ぐ例を説明したが、栓４４０は、実施の形態２，３に係るリード線導出部２００，３００に形成された空間を塞ぐ閉塞部材として用いてもよい。 In the fourth embodiment, the example in which the space 400b formed in the lead wire lead-out portion 400 having the same shape as the lead wire lead-out portion 10 according to the first embodiment is blocked by the plug 440 has been described. You may use as a closure member which plugs up the space formed in lead wire derivation parts 200 and 300 concerning forms 2 and 3.
　また、実施の形態２から４に示す一体リード線導出部品および別体リード線導出部品は、一体リード線導出部品と別体リード線導出部品との嵌め合いを保持するために、封止部、係り止め足および爪部を有しているが、実施の形態２から４ではその説明を省略する。封止部、係り止め足および爪部の形状は、実施の形態１と同一または同等であってもよく、実施の形態１と異なっていてもよい。 In addition, the integrated lead wire lead-out component and the separate lead wire lead-out component shown in the second to fourth embodiments are provided with a sealing portion in order to maintain the fitting between the integral lead wire lead-out component and the separate lead wire lead-out component, Although it has a retaining foot and a claw part, the description is abbreviate | omitted in Embodiment 2-4. The shapes of the sealing portion, the retaining foot, and the claw portion may be the same as or equivalent to those in the first embodiment, and may be different from those in the first embodiment.
　また、実施の形態１から４では、リード線導出部におけるセンサリード線用の挿通溝に、センサリード線が挿通されない場合において、センサリード線用の挿通溝を塞ぐ構成を説明した。しかしながら、当該構成は、センサリード線用の挿通溝に限らず、リード線導出部における電源リード線用の挿通溝に電源リード線が挿通されない場合には、電源リード線用の挿通溝を有するリード線導出部材、または電源リード線用の挿通空間に適用しても良い。 Further, in the first to fourth embodiments, the configuration in which the sensor lead wire insertion groove is blocked when the sensor lead wire is not inserted into the sensor lead wire insertion groove in the lead wire lead-out portion has been described. However, the configuration is not limited to the insertion groove for the sensor lead wire. If the power supply lead wire is not inserted into the insertion groove for the power supply lead wire in the lead wire lead-out portion, the lead having the insertion groove for the power supply lead wire is used. You may apply to the insertion space for a wire lead-out member or a power supply lead wire.
　また、実施の形態１，４では、３枚の板状部材から構成されるリード線導出部のうち、中間部の板状部材が、リード線配線部品と一体形成されている形態を示したが、中間部以外の板状部材がリード線配線部品と一体形成されていても良い。 In the first and fourth embodiments, among the lead wire lead-out portions composed of three plate members, the intermediate plate member is formed integrally with the lead wire wiring component. A plate-like member other than the intermediate portion may be integrally formed with the lead wire wiring component.
　また実施の形態２～４に係るリード線導出部を備えたモールド電動機は、実施の形態１で説明した空気調和機１３００の室内機１１００および室外機１２００の少なくとも一方の送風機用電動機として用いることができる。これにより送風機用電動機の固定子内部への水の浸入が抑制され、低コストで品質の良い空気調和機１３００を得ることができる。 In addition, the molded motor provided with the lead wire lead-out portion according to Embodiments 2 to 4 is used as the blower motor of at least one of the indoor unit 1100 of the air conditioner 1300 and the outdoor unit 1200 described in Embodiment 1. it can. As a result, water permeation into the stator of the blower motor can be suppressed, and the air conditioner 1300 with good quality can be obtained at low cost.
