本発明は上記問題に鑑みてなされたものであり、従来に比べて組立作業効率が高く、密封端子の再利用が可能な、電動圧縮機を提供することを目的とする。 In electric compressors in which insulating resin is poured into the housing to insulate the connection between the conductive pins of the sealed terminal and the lead wires of the electric motor, a curing waiting time for the insulating resin poured into the housing occurs. There is a problem that the assembly work efficiency is reduced and the sealed terminal is hardened with resin and cannot be reused.
The present invention has been made in view of the above problems, and an object of the present invention is to provide an electric compressor that has higher assembly work efficiency than conventional ones and can reuse a sealed terminal.

本発明に係る電動圧縮機においては、ハウジングの内面全体と密封端子を取り付けた蓋部材の内面とに絶縁処理が施されているので、密封端子の導電ピンとモータのリード線との接続部からハウジングと蓋部材とへ漏電しない。ハウジング内面全体と密封端子を取り付けた蓋部材の内面とは、絶縁性樹脂コーティング等により予め絶縁処理しておけば良い。本発明に係る電動圧縮機においては、密封端子の導電ピンとモータのリード線との接続部を絶縁するために圧縮機の組立中にハウジング内に絶縁性樹脂を流し込む必要がないので、従来に比べて組立作業効率が高く、且つ密封端子の再利用が可能である。 In order to solve the above problems, in the present invention, a compression mechanism, an electric motor that drives the compression mechanism, a connection portion between a conductive pin of a sealed terminal connected to an external power source, and a lead wire of the electric motor, and a compression mechanism And an electric motor and a housing that accommodates the connecting portion, and a lid member to which a sealed terminal is attached closes an opening formed in the housing, the lid member having an entire inner surface of the housing and a sealed terminal attached An electric compressor is provided in which an inner surface is insulated.
In the electric compressor according to the present invention, since the entire inner surface of the housing and the inner surface of the lid member to which the sealing terminal is attached are insulated, the housing is connected to the connecting portion between the conductive pin of the sealing terminal and the lead wire of the motor. And no leakage to the lid. The entire inner surface of the housing and the inner surface of the lid member to which the sealing terminal is attached may be insulated in advance by an insulating resin coating or the like. In the electric compressor according to the present invention, in order to insulate the connection portion between the conductive pin of the sealed terminal and the lead wire of the motor, it is not necessary to pour the insulating resin into the housing during the assembly of the compressor. As a result, the assembly work efficiency is high and the sealed terminal can be reused.

本発明においては、圧縮機構と、圧縮機構を駆動する電動モータと、外部電源に接続された密封端子の導電ピンと電動モータのリード線との接続部と、圧縮機構と電動モータと接続部とを収容するハウジングとを備え、密封端子を取り付けた蓋部材がハウジングに形成した開口を塞いだ電動圧縮機であって、電動モータを収容する第１区画と、密封端子の導電ピンと電動モータのリード線との接続部を収容する第２区画と、圧縮機構を収容する第３区画区とがハウジング内に形成され、ハウジング内面の第１区画と第２区画とに対峙する部位と密封端子を取り付けた蓋部材の内面とに絶縁処理が施されていることを特徴とする電動圧縮機を提供する。

It is possible to leak electricity only to remote parts. By increasing the length of the leakage path, leakage from the connecting portion between the conductive pin of the sealed terminal and the lead wire of the motor is suppressed to the housing.

本発明においては、圧縮機構と、圧縮機構を駆動する電動モータと、外部電源に接続された密封端子の導電ピンと電動モータのリード線との接続部と、圧縮機構と電動モータと接続部とを収容するハウジングとを備え、密封端子を取り付けた蓋部材がハウジングに形成した開口を塞いだ電動圧縮機であって、密封端子の導電ピンと電動モータのリード線との接続部の導電体が剥き出しになっている部位の表面に絶縁処理が施されていることを特徴とする電動圧縮機を提供する。
本発明に係る電動圧縮機においては、密封端子の導電ピンと電動モータのリード線との接続部の導電体が剥き出しになっている部位の表面に絶縁処理が施されているので、密封端子の導電ピンとモータのリード線との接続部からは電流は漏出できず、ハウジングと蓋部材とへ漏電できない。絶縁性樹脂コーティング等により、密封端子の導電ピンと電動モータのリード線との接続部の導電体が剥き出しになっている部位の表面を容易に絶縁処理でき、塗膜の乾燥時間も短い。本発明に係る電動圧縮機においては、密封端子の導電ピンとモータのリード線との接続部を絶縁するために圧縮機の組立中にハウジング内に絶縁性樹脂を流し込む必要がないので、従来に比べて組立作業効率が高く、且つ密封端子の再利用が可能である。 In the present invention, a compression mechanism, an electric motor that drives the compression mechanism, a connection portion between a conductive pin of a sealed terminal connected to an external power source and a lead wire of the electric motor, a compression mechanism, an electric motor, and a connection portion are provided.

密封端子８が取り付けられた蓋部材１７が、ハウジング１０の筒状突起部１０ｃの先端に固定され、筒状突起部１０ｃの先端開口を塞いでいる。
ハウジング１０の内面全体と蓋部材１７の内面とに、絶縁性樹脂コーティング等の絶縁処理が施されている。 As shown in FIG. 1, the scroll compressor A includes a fixed scroll 1 having an end plate having a discharge hole 1a formed at the center thereof and a spiral body, and a movable scroll 2 having an end plate and a spiral body. ing. The spiral body of the fixed scroll 1 and the spiral body of the movable scroll 2 are engaged with each other to form a plurality of pairs of working spaces 3.
A main shaft 4, a motion conversion mechanism 5 that converts the rotational motion of the main shaft 4 into a turning motion and transmits it to the movable scroll 2, and a rotation prevention mechanism 6 that prevents the movable scroll 2 from rotating are disposed.
The fixed scroll 1, the movable scroll 2, the motion conversion mechanism 5, and the rotation prevention mechanism 6 form a compression mechanism.
An electric motor 7 composed of a stator 7a and a rotor 7b is disposed. The electric motor 7 drives the main shaft 4 and drives the compression mechanism via the main shaft 4.
A connecting portion 9 between the conductive pin 8 a of the sealed terminal 8 connected to an external power source and the lead wire 7 c of the motor 7 is disposed slightly apart from the motor 7.
The compression mechanism, the main shaft 4, the motor 7, and the connection portion 9 are accommodated in the housing 10. An end portion of the main shaft 4 on the motor 7 side is rotatably supported by a boss portion 10 a formed on the housing 10, and an end portion on the motion conversion mechanism 5 side is rotatable by a center plate 11 disposed in the housing 10. It is supported.

A suction port 13 is formed at a portion of the housing 10 that faces the first section 12a. The third section 12 c is divided into a suction chamber 14 and a discharge chamber 15 with the end plate of the fixed scroll 1 as a boundary. The suction chamber 14 communicates with the first compartment 12a through an opening 11a formed in the center plate 11. A discharge port 16 is formed at a portion of the housing 10 facing the discharge chamber 15.
A lid member 17 to which the sealing terminal 8 is attached is fixed to the tip of the cylindrical projection 10c of the housing 10 and closes the tip opening of the cylindrical projection 10c.
The entire inner surface of the housing 10 and the inner surface of the lid member 17 are subjected to an insulation treatment such as an insulating resin coating.

本実施例に係る電動圧縮機Ａにおいては、電動モータ７により主軸４が回転駆動される。主軸４の回転は、運動変換機構５を経て旋回運動に変換され、可動スクロール２に伝達される。可動スクロール２の自転は自転阻止機構６により阻止される。
可動スクロール２が旋回することにより、空調装置の低圧側回路から吸入ポート１３と第１区画１２ａとを経て吸入室１４へ流入した冷媒ガスが、渦巻体の径方向外方から一対の作動空間３へ取り込まれる。前記一対の作動空間３は、体積を減少させつつ渦巻体の中心部へ向けて移動し、最終的に相互に連通して吐出孔１ａに連通する。作動空間３内で圧縮された冷媒ガスは、吐出孔１ａを開閉する吐出弁を経て吐出室１５に吐出し、吐出ポート１６を通って、空調装置の高圧側回路へ流出する。 In the electric compressor A according to this embodiment, the main shaft 4 is rotationally driven by the electric motor 7.

The rotation of the movable scroll 2 is blocked by the rotation blocking mechanism 6.
As the movable scroll 2 turns, the refrigerant gas flowing into the suction chamber 14 from the low-pressure side circuit of the air conditioner through the suction port 13 and the first compartment 12a flows from the outside of the spiral body in the radial direction. It is taken in. The pair of working spaces 3 move toward the center of the spiral body while reducing the volume, and finally communicate with each other and communicate with the discharge hole 1a. The refrigerant gas compressed in the working space 3 is discharged to the discharge chamber 15 through the discharge valve that opens and closes the discharge hole 1a, and flows out to the high-pressure side circuit of the air conditioner through the discharge port 16.

本実施例に係る電動圧縮機Ａにおいては、ハウジング１０の内面全体と密封端子８を取り付けた蓋部材１７の内面とに絶縁処理が施されているので、密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９からハウジング１０と蓋部材１７とへ漏電しない。ハウジング１０の内面全体と蓋部材１７の内面とは、絶縁性樹脂コーティング等により予め絶縁処理しておけば良い。電動圧縮機Ａにおいては、密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９を絶縁するために圧縮機の組立中にハウジング１０内に絶縁性樹脂を流し込む必要がないので、従来に比べて組立作業効率が高く、且つ密封端子８の再利用が可能である。 In the electric compressor A according to this embodiment, since the entire inner surface of the housing 10 and the inner surface of the lid member 17 to which the sealing terminal 8 is attached are insulated, the conductive pins 8a of the sealing terminal 8 and the motor 7 are insulated. No leakage occurs from the connecting portion 9 to the lead wire 7 c to the housing 10 and the lid member 17. The entire inner surface of the housing 10 and the inner surface of the lid member 17 may be insulated in advance by an insulating resin coating or the like. In the electric compressor A, in order to insulate the connection portion 9 between the conductive pin 8a of the sealing terminal 8 and the lead wire 7c of the motor 7, there is no need to pour insulating resin into the housing 10 during assembly of the compressor. The assembly work efficiency is higher than in the prior art, and the sealing terminal 8 can be reused.

ハウジング１０の内面全体と密封端子８を取り付けた蓋部材１７の内面とに絶縁処理を施すのに代えて、ハウジング１０の内面の第１区画１２ａと第２区画１２ｂとに対峙する部位と密封端子８を取り付けた蓋部材１７の内面とに絶縁処理を施しても良い。
ハウジング１０の内面の第１区画１２ａと第２区画１２ｂとに対峙する部位と蓋部材１７の内面とに絶縁処理が施されているので、密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９からハウジング１０の近傍部位と蓋部材１７とへは漏電できず、圧縮機構を収容する第３区画１２ｃに対峙するハウジング１０の遠隔部位にしか漏電できない。漏電経路長が長くなることにより、密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９からハウジング１０への漏電が抑制される。密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９を絶縁するために圧縮機の組立中にハウジング１０内に絶縁性樹脂を流し込む必要がないので、従来に比べて組立作業効率が高く、且つ密封端子８の再利用が可能である。 Instead of applying insulation treatment to the entire inner surface of the housing 10 and the inner surface of the lid member 17 to which the sealing terminal 8 is attached, a portion of the inner surface of the housing 10 facing the first section 12a and the second section 12b and the sealing terminal You may insulate the inner surface of the lid member 17 to which 8 is attached.
Since the insulation treatment is applied to the portion of the inner surface of the housing 10 facing the first section 12a and the second section 12b and the inner surface of the lid member 17, the conductive pin 8a of the sealing terminal 8 and the lead wire 7c of the motor 7 are provided. From the connecting portion 9 to the vicinity of the housing 10 and the lid member 17, no leakage can occur, and only the remote portion of the housing 10 facing the third section 12 c that houses the compression mechanism can leak. By increasing the leakage path length, leakage from the connecting portion 9 between the conductive pin 8a of the sealing terminal 8 and the lead wire 7c of the motor 7 to the housing 10 is suppressed. Insulating resin does not need to be poured into the housing 10 during assembly of the compressor in order to insulate the connecting portion 9 between the conductive pin 8a of the sealed terminal 8 and the lead wire 7c of the motor 7, and therefore, assembly work is possible as compared with the conventional case The efficiency is high and the sealing terminal 8 can be reused.

ハウジング１０の内面全体と密封端子８を取り付けた蓋部材１７の内面とに絶縁処理を施すのに代えて、ハウジング１０の内面の第２区画１２ｂに対峙する部位と密封端子８を取り付けた蓋部材１７の内面とに絶縁処理を施しても良い。
ハウジング１０の内面の第２区画１２ｂに対峙する部位と蓋部材１７の内面とに絶縁処理が施されているので、密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９からハウジング１０の近傍部位と蓋部材１７とへは漏電できず、モータ７を収容する第１区画１２ａまたは圧縮機構を収容する第３区画１２ｃに対峙するハウジング１０の遠隔部位にしか漏電できない。漏電経路長が長くなることにより、密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９からハウジング１０への漏電が抑制される。密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９を絶縁するために圧縮機の組立中にハウジング１０内に絶縁性樹脂を流し込む必要がないので、従来に比べて組立作業効率が高く、且つ密封端子８の再利用が可能である。 Instead of applying insulation treatment to the entire inner surface of the housing 10 and the inner surface of the lid member 17 to which the sealing terminal 8 is attached, a portion facing the second section 12b of the inner surface of the housing 10 and the lid member to which the sealing terminal 8 is attached The inner surface of 17 may be insulated.
Since the insulation treatment is applied to the portion of the inner surface of the housing 10 facing the second section 12 b and the inner surface of the lid member 17, the connection portion 9 between the conductive pin 8 a of the sealing terminal 8 and the lead wire 7 c of the motor 7 is used. Electrical leakage cannot occur in the vicinity of the housing 10 and the lid member 17, and electrical leakage can only occur in the remote portion of the housing 10 that faces the first compartment 12 a that houses the motor 7 or the third compartment 12 c that houses the compression mechanism. By increasing the leakage path length, leakage from the connecting portion 9 between the conductive pin 8a of the sealing terminal 8 and the lead wire 7c of the motor 7 to the housing 10 is suppressed. Insulating resin does not need to be poured into the housing 10 during assembly of the compressor in order to insulate the connecting portion 9 between the conductive pin 8a of the sealed terminal 8 and the lead wire 7c of the motor 7, and therefore, assembly work is possible as compared with the conventional case. The efficiency is high and the sealing terminal 8 can be reused.

ハウジング１０の内面全体と密封端子８を取り付けた蓋部材１７の内面とに絶縁処理を施すのに代えて、密封端子８の導電ピン８ａと電動モータ７のリード線７ｃとの接続部の導電体が剥き出しになっている部位の表面に絶縁処理を施しても良い。
密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９からは電流は漏出できず、ハウジング１０と蓋部材１７とへ漏電できない。絶縁性樹脂コーティング等により、密封端子８の導電ピン８ａと電動モータ７のリード線７ｃとの接続部９の導電体が剥き出しになっている部位の表面を容易に絶縁処理でき、塗膜の乾燥時間も短い。密封端子８の導電ピン８ａとモータ７のリード線７ｃとの接続部９を絶縁するために圧縮機の組立中にハウジング１０内に絶縁性樹脂を流し込む必要がないので、従来に比べて組立作業効率が高く、且つ密封端子８の再利用が可能である。 Instead of applying insulation treatment to the entire inner surface of the housing 10 and the inner surface of the lid member 17 to which the sealing terminal 8 is attached, the conductor at the connection portion between the conductive pin 8a of the sealing terminal 8 and the lead wire 7c of the electric motor 7 is used. Insulation treatment may be applied to the surface of the exposed part.
The current cannot leak from the connecting portion 9 between the conductive pin 8 a of the sealing terminal 8 and the lead wire 7 c of the motor 7, and cannot leak to the housing 10 and the lid member 17. By insulating resin coating or the like, the surface of the portion where the conductor of the connecting portion 9 between the conductive pin 8a of the sealed terminal 8 and the lead wire 7c of the electric motor 7 is exposed can be easily insulated, and the coating film can be dried. The time is short. Insulating resin does not need to be poured into the housing 10 during assembly of the compressor in order to insulate the connecting portion 9 between the conductive pin 8a of the sealed terminal 8 and the lead wire 7c of the motor 7, and therefore, assembly work is possible as compared with the conventional case. The efficiency is high and the sealing terminal 8 can be reused.
