FIG. 1 is a cross-sectional explanatory view illustrating an embodiment of the electric compressor of the present invention.
In FIG. 1, reference numeral 10 denotes an internal intermediate pressure multistage compression rotary electric compressor using carbon dioxide (CO 2 ) as a refrigerant. The electric compressor 10 includes a cylindrical sealed container 12 made of an aluminum-based metal, The electric element 14 arranged and housed above the internal space of the sealed container 12 and the lower rotary compression element 32 (first stage) arranged below the electric element 14 and driven by the rotating shaft 16 of the electric element 14. ) And an upper rotary compression element 34 (second stage).
The sealed container 12 has an oil reservoir at the bottom, a container body 12A that houses the electric element 14 and the rotary compression mechanism 18, and a generally bowl-shaped end cap (lid body) 12B that closes the upper opening of the container body 12A. It is configured.
A circular mounting hole 12D is formed at the center of the upper surface of the end cap 12B, and a terminal 20 for supplying power to the electric element 14 is fixedly mounted in the mounting hole 12D.

電動要素１４は所謂磁極集中巻き式のＤＣモータであり、密閉容器１２の上部空間の内周面に沿って環状に取り付けられたステータ２２と、このステータ２２の内側に若干の間隔を設けて挿入設置されたロータ２４とからなる。このロータ２４は中心を通り鉛直方向に延びる回転軸１８に固定されている。
ステータ２２は、ドーナッツ状の電磁鋼板を積層した積層体２６と、この積層体２６の歯部に直巻さ（集中巻き）方式により巻装されたステータコイル２８を有している。また、ロータ２４はステータ２２と同様に電磁鋼板の積層体３０で形成され、この積層体３０内に永久磁石ＭＧを挿入して形成されている。 The electric element 14 is a so-called magnetic pole concentrated winding type DC motor, and is inserted into the stator 22 in an annular shape along the inner peripheral surface of the upper space of the hermetic container 12, and is inserted inside the stator 22 with a slight gap therebetween. The rotor 24 is installed. The rotor 24 is fixed to a rotating shaft 18 that passes through the center and extends in the vertical direction.
The stator 22 includes a laminated body 26 in which donut-shaped electromagnetic steel plates are laminated, and a stator coil 28 wound around the teeth of the laminated body 26 by a direct winding (concentrated winding) method. Similarly to the stator 22, the rotor 24 is formed of a laminated body 30 of electromagnetic steel plates, and is formed by inserting a permanent magnet MG into the laminated body 30.

ターミナル２０は図示しない外部電源に接続されており、ターミナル２０に接続するリード線１と、電動要素１４のステータコイル２８に接続するモータ引出線２とが接続部３を介して接続してあり、図示しない外部電源からターミナル２０→リード線１→接続部３→モータ引出線２を経てステータコイル２８に給電するようになっている。
そして、後述するように接続部３はその周囲が絶縁性プラスチックシートから形成されてなるカバー４で包まれている。 The terminal 20 is connected to an external power source (not shown), and the lead wire 1 connected to the terminal 20 and the motor lead wire 2 connected to the stator coil 28 of the electric element 14 are connected via the connection portion 3. Electric power is supplied to the stator coil 28 from an external power source (not shown) via the terminal 20 → the lead wire 1 → the connection portion 3 → the motor lead wire 2.
As will be described later, the connection portion 3 is wrapped with a cover 4 formed around an insulating plastic sheet.

下段の回転圧縮要素３２と上段の回転圧縮要素３４との間には中間仕切板３６が狭持されている。即ち、下段の回転圧縮要素３２と上段の回転圧縮要素３４は、中間仕切板３６と、この中間仕切坂３６の上下に配置された上シリンダ３８、下シリンダ４０と、この上下シリンダ３８、４０内を、１８０度の位相差を有して回転軸１６に設けられた上下遍心部４２、４４により遍心回転される上下ローラ４６、４８と、この上下ローラ４６、４８に当接して上下シリンダ３８、４０内をそれぞれ低圧室側と高圧室側に区画するベーン５０、５２と、上シリンダ３８の上側の開口面および下シリンダ４０の下側の開口面を閉塞して回転軸１６の軸受けを兼用する支持部材としての上部支持部材５４および下部支持部材５６にて構成されている。   An intermediate partition plate 36 is sandwiched between the lower rotary compression element 32 and the upper rotary compression element 34. That is, the lower rotary compression element 32 and the upper rotary compression element 34 include an intermediate partition plate 36, an upper cylinder 38 and a lower cylinder 40 disposed above and below the intermediate partition slope 36, and the upper and lower cylinders 38, 40. The upper and lower rollers 46 and 48 are rotated omnidirectionally by upper and lower omnidirectional portions 42 and 44 provided on the rotary shaft 16 with a phase difference of 180 degrees, and the upper and lower 38 and 40 are divided into a low pressure chamber side and a high pressure chamber side, respectively, and the upper opening surface of the upper cylinder 38 and the lower opening surface of the lower cylinder 40 are closed to support the bearing of the rotary shaft 16. The upper support member 54 and the lower support member 56 are also used as the supporting members.

一方、上部支持部材５４および下部支持部材５６には、図示しない吸込ポートにて上下シリンダ３８、４０の内部とそれぞれ連通する吸込通路６０（上側の吸込通路は図示せず）と、一部を凹陥させ、この凹陥部を上部カバー６６、下部カバー６８にて閉塞することにより形成される吐出消音室６２、６４とが設けられている。
尚、吐出消音室６４と密閉容器１２内とは、上下シリンダ３８、４０や中間仕切板３６を貫通する連通路にて連通されており、連通路の上端には中間吐出管１２１が立設され、この中間吐出管１２１から下段の回転圧縮要素３２で圧縮された中間圧の冷媒ガスが密閉容器１２内に吐出される。 On the other hand, the upper support member 54 and the lower support member 56 are respectively provided with a suction passage 60 (the upper suction passage is not shown) that communicates with the inside of the upper and lower cylinders 38 and 40 through a suction port (not shown), and a part thereof is recessed. Discharge silencing chambers 62 and 64 formed by closing the recessed portion with an upper cover 66 and a lower cover 68 are provided.
The discharge silencer chamber 64 and the inside of the sealed container 12 are communicated with each other through a communication passage that penetrates the upper and lower cylinders 38 and 40 and the intermediate partition plate 36, and an intermediate discharge pipe 121 is provided upright at the upper end of the communication passage. The intermediate pressure refrigerant gas compressed by the lower rotary compression element 32 is discharged from the intermediate discharge pipe 121 into the sealed container 12.

そして、潤滑油としてのオイルは、例えば鉱物油（ミネラルオイル）、アルキベンゼン油、エーテル油、エステル油、ＰＡＧ（ポリアルキルグリコール）など既存のオイルが使用される。   For example, mineral oil (mineral oil), alkylbenzene oil, ether oil, ester oil, or PAG (polyalkyl glycol) is used as the lubricating oil.

密閉容器１２の容器本体１２Ａの側面には、上部支持部材５４と下部支持部材５６の吸込通路６０（上側は図示せず）、吐出消音室６２、上部カバー６６の上側（電動要素１４の下端に略対応する位置）に対応する位置に、スリーブ１４２および１４３が溶接固定されている。
また、スリーブ１４２内には下シリンダ４０に冷媒ガスを導入するための冷媒導入管９４の一端が挿入接続され、この冷媒導入管９４の一端は下シリンダ４０の吸込通路６０と連通する。また、スリーブ１４３内には冷媒吐出管９６の一端が挿入接続され、この冷媒吐出管９６の一端は吐出消音室６２と連通通する。 On the side surface of the container main body 12A of the sealed container 12, the suction passage 60 (upper side is not shown) of the upper support member 54 and the lower support member 56, the discharge silencer chamber 62, the upper side of the upper cover 66 (on the lower end of the electric element 14). The sleeves 142 and 143 are fixed by welding at positions corresponding to the substantially corresponding positions.
In addition, one end of a refrigerant introduction pipe 94 for introducing refrigerant gas into the lower cylinder 40 is inserted and connected in the sleeve 142, and one end of the refrigerant introduction pipe 94 communicates with the suction passage 60 of the lower cylinder 40. One end of a refrigerant discharge pipe 96 is inserted and connected into the sleeve 143, and one end of the refrigerant discharge pipe 96 communicates with the discharge silencer chamber 62.

図示しない外部電源からターミナル２０→リード線１→接続部３→モータ引出線２を経てステータコイル２８に通電されると、電動要素１４が起動してロータ２４が回転する。この回転により回転軸１６と一体に設けた上下偏心部４２、４４に嵌合された上下ローラ４６、４８が上下シリンダ３８、４０内を偏心回転する。
これにより、冷媒導入管９４および下部支持部材５６に形成された吸込通路６０を経由して図示しない吸込ポートからシリンダ４０の低圧室側に吸入された低圧の冷媒ガスは、ローラ４８とベーン５２の動作により圧縮されて中間圧となり下シリンダ４０の高圧室側より図示しない連通路を経て中間吐出管１２１から密閉容器１２内に吐出される。これによって、密閉容器１２内は中間圧となる。 When the stator coil 28 is energized from an external power source (not shown) through the terminal 20 → the lead wire 1 → the connection portion 3 → the motor lead wire 2, the electric element 14 is activated and the rotor 24 rotates. By this rotation, the upper and lower rollers 46 and 48 fitted to the upper and lower eccentric portions 42 and 44 provided integrally with the rotary shaft 16 rotate eccentrically in the upper and lower cylinders 38 and 40.
Thereby, the low-pressure refrigerant gas sucked into the low-pressure chamber side of the cylinder 40 from the suction port (not shown) via the suction passage 60 formed in the refrigerant introduction pipe 94 and the lower support member 56 is transferred between the roller 48 and the vane 52. It is compressed by the operation to become an intermediate pressure, and is discharged from the intermediate discharge pipe 121 into the sealed container 12 through a communication path (not shown) from the high pressure chamber side of the lower cylinder 40. As a result, the inside of the sealed container 12 becomes an intermediate pressure.

そして、中間圧の冷媒ガスは上部支持部材５４に形成された図示しない吸込通路を経由して、図示しない吸込ポートから上段の回転圧縮要素３４の上シリンダ３８の低圧室側に吸入され、ローラ４６とベーン５０の動作により２段目の圧縮が行われて高圧高温の冷媒ガスとなり、高圧室側から図示しない吐出ポートを通り上部支持部材５４に形成された吐出消音室６２を経て冷媒吐出管９６より外部に吐出され、循環して使用される。   The intermediate-pressure refrigerant gas is drawn into a low pressure chamber side of the upper cylinder 38 of the upper rotary compression element 34 from a suction port (not shown) via a suction passage (not shown) formed in the upper support member 54, and the roller 46. Then, the second stage of compression is performed by the operation of the vane 50 to form high-pressure and high-temperature refrigerant gas, and from the high-pressure chamber side, through a discharge port (not shown), and through a discharge silencer chamber 62 formed in the upper support member 54, It is discharged to the outside and used in circulation.

図２（１）〜（６）は、図１に示した本発明の電動圧縮機のリード線とモータ引出線との接続部を包むカバーを作成し、接続部を包む工程の一実施の形態を説明する説明図である。
図２（１）において、厚さ約５０μｍ程度のポリエステル、ポリアミド、ポリオレフィン、ポリカーボネート、エンジニアリングプラスチック、熱可塑性エラストマー、熱硬化性プラスチックなどの冷媒や潤滑油に耐性があり、耐熱性、強度などに優れる特性を有する絶縁性プラスチックシート７０を準備する。厚さは２〜４回など複数回巻いてチューブ状にした時に、重ね厚さが約１５０μｍ程度になるようにすることが強度、安定性、固定性などの観点から好ましい。１回巻きでは形成されるチューブが不安定であり、強度も低く、チューブを位置ぎめして密着して固定することができなくなる。 2 (1) to 2 (6) show an embodiment of a process for creating a cover for wrapping the connecting portion between the lead wire and the motor lead wire of the electric compressor of the present invention shown in FIG. 1, and wrapping the connecting portion. It is explanatory drawing explaining these.
In FIG. 2 (1), it is resistant to refrigerants and lubricating oils such as polyester, polyamide, polyolefin, polycarbonate, engineering plastics, thermoplastic elastomers, thermosetting plastics and the like having a thickness of about 50 μm, and is excellent in heat resistance and strength. An insulating plastic sheet 70 having characteristics is prepared. It is preferable from the viewpoint of strength, stability, fixability, and the like that the thickness is about 150 μm when the thickness is wound a plurality of times such as 2 to 4 times to form a tube. In a single turn, the tube formed is unstable, the strength is low, and the tube cannot be positioned and closely adhered.

そして図２（２）に示したように、この絶縁性プラスチックシート７０を複数回巻いてチューブ７１（例えば長さ約５０ｍｍ、内径約５ｍｍ）に形成する。   Then, as shown in FIG. 2 (2), the insulating plastic sheet 70 is wound a plurality of times to form a tube 71 (for example, a length of about 50 mm and an inner diameter of about 5 mm).

そして図２（３）に示したように、このチューブ７１の一端の所定部を公知の方法、装置を用いて溶着する。７２は溶着部、７３は未溶着部を示す。溶着部７２の形状や寸法などは、チューブ７１の溶着した側の反対側にリード線１を挿入でき、そしてチューブ７１の未溶着部７３にモータ引出線２を密着して挿入して固定できればよく、特に限定されるものではない。
この未溶着部７３にモータ引出線２を挿入して密着して固定するので、未溶着部７３の内径Ｄ１とモータ引出線２の外径Ｄ２（例えば約０．５〜１．２ｍｍ）とがほぼ同じかあるいは未溶着部７３の内径Ｄ１がモータ引出線２の外径Ｄ２よりやや大きくなるように溶着することが肝要である。
すなわち、Ｄ１≧Ｄ２となるようにするが、未溶着部７３の内径Ｄ１が、モータ引出線２の外径Ｄ２よりあまり大き過ぎると、ブカブカになり、位置が定まらず、位置ぎめして密着して固定することがでさなくなる。 Then, as shown in FIG. 2 (3), a predetermined portion at one end of the tube 71 is welded using a known method and apparatus. Reference numeral 72 denotes a welded portion, and 73 denotes an unwelded portion. The shape and dimensions of the welded portion 72 may be such that the lead wire 1 can be inserted on the opposite side of the welded side of the tube 71, and the motor lead wire 2 can be inserted into the unwelded portion 73 of the tube 71 and fixed. There is no particular limitation.
Since the motor lead wire 2 is inserted into and closely fixed to the unwelded portion 73, the inner diameter D1 of the unwelded portion 73 and the outer diameter D2 (for example, about 0.5 to 1.2 mm) of the motor lead wire 2 are obtained. It is important that welding is performed so that the inner diameter D1 of the unwelded portion 73 is substantially the same or slightly larger than the outer diameter D2 of the motor lead wire 2.
That is, D1 ≧ D2 is satisfied, but if the inner diameter D1 of the unwelded portion 73 is too large than the outer diameter D2 of the motor lead-out wire 2, the position becomes unsteady and the position is not fixed, and it is positioned and closely adhered. Can not be fixed.

そして図２（４）に示したように、チューブ７１の一端からモータ引出線２を挿入し、チューブ７１の他端から少し引き出す。７４はリード線１と接続するための端部である。   Then, as shown in FIG. 2 (4), the motor lead wire 2 is inserted from one end of the tube 71 and pulled out a little from the other end of the tube 71. Reference numeral 74 denotes an end for connecting to the lead wire 1.

次に、図２（５）に示したように、リード線１とモータ引出線２を接続し、ハンダ溶接する。７５はハンダ溶接部を示す。   Next, as shown in FIG. 2 (5), the lead wire 1 and the motor lead wire 2 are connected and soldered. Reference numeral 75 denotes a solder weld.

そして図２（６）に示したように、ハンダ溶接した後、チューブ７１を所定の位置に移動させ、そのままその位置に固定して接続部３をカバー４で包むことができる。   Then, as shown in FIG. 2 (6), after solder welding, the tube 71 can be moved to a predetermined position, fixed at that position, and the connecting portion 3 can be wrapped with the cover 4.
