Description
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. A power supply lead wire holding component that holds the power supply lead wire, and a sensor lead wire holding component that is assembled to the lead-out portion and holds the sensor lead wire. An insertion groove for the sensor lead wire is formed on one end side of the lead-out portion, and an insertion groove for the power supply lead wire is formed on the other end side of the lead-out portion. The power supply lead wire and the sensor lead wire are arranged in two steps from the front and back of the lead-out portion. It is pulled out at.
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.

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。

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.

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.

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.
図7に示すように電源リード線30を構成する3本のリード線の各々は、120°間隔で配線部1aに配置された3つのリード線端末保持部1fの各々に引回される。電源リード線30の端末の被覆が剥がされ、端末がリード線端末保持部1fの壁1gの内側に接することで、電源リード線30の位置決めがなされる。
As shown in FIG. 7, each of the three lead wires constituting the power supply lead wire 30 is routed to each of the three lead wire terminal holding portions 1f arranged in the wiring portion 1a at intervals of 120 °. 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.

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 power supply lead wire 30 is accommodated in each of the three grooves 220a. The width of each of the three grooves 220a represents the width between adjacent grooves 220a.
5つの溝220bの各々は、センサリード線用の挿通溝であり、5つの溝220bの各々の幅は、センサリード線40の外径よりも大きい。5つの溝220bの各々にはセンサリード線40が収められる。5つの溝220bの各々の幅は、隣接する溝220bの間の幅を表す。
Each of the five grooves 220b is an insertion groove for a sensor lead wire, and the width of each of the five grooves 220b is larger than the outer diameter of the sensor lead wire 40. 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. Further, the five grooves 220b of the separate lead wire lead-out component 220 are formed at positions facing each of the five grooves 210b of the integral lead wire lead-out component 210, respectively. The power supply lead wire 30 is inserted and held in a cylindrical space surrounded by the groove 210a and the groove 220a. The sensor lead wire 40 is inserted and held in a cylindrical space formed by being surrounded by the groove 210b and the groove 220b.
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。

When the outer diameter of the power supply lead wire 30 and the outer diameter of the sensor lead wire 40 are equal, the lead wire contact surface 211 has the number of the power supply lead wires 30 instead of the three grooves 210a and the five grooves 210b. Eight grooves 210a equal to the total number of sensor lead wires 40 are formed, or eight grooves 210b equal to the number are formed.
同様に、リード線当接面221には、3つの溝220aおよび溝220b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220aが形成され、または当該数と等しい8つの溝220bが形成される。
Similarly, eight grooves 220a equal to the total number of the power supply lead wires 30 and the sensor lead wires 40 are formed on the lead wire contact surface 221 instead of the three grooves 220a and 220b. 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.

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.

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. It is equal to or larger than the inner diameter of the space 400b.
栓440の数はセンサリード線40の本数と等しく、円筒状の5つの空間400bの各々には、栓440がひとつずつ詰められている。すなわち5つの栓440が詰められている。栓440を用いることによって、円筒状の空間400bが封止され、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。
The number of plugs 440 is equal to the number of sensor lead wires 40, and one plug 440 is packed in each of the five cylindrical spaces 400b. 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.
