Description

本発明は、電動圧縮機に関する。 The present invention relates to an electric compressor.

特許文献１に開示の電動圧縮機は、冷媒を圧縮する圧縮部と、圧縮部を駆動する電動モータと、電動モータを駆動するモータ駆動回路と、モータ駆動回路と電気的に接続された導電部材と、電動モータから引き出されたモータ配線とを備えている。また、電動圧縮機は、モータ配線と導電部材とを電気的に接続する接続端子と、接続端子を内部に収容する絶縁性の端子収容部材と、圧縮部、電動モータ、及び端子収容部材を収容するハウジングとを備えている。端子収容部材は、接続端子が収容されるクラスタブロックと、クラスタブロック全体を覆うカバー部材とを有している。クラスタブロックは、内部に接続端子を収容するための開口部を有している。クラスタブロックの開口部は、カバー部材によって塞がれている。 The electric compressor disclosed in Patent Document 1 includes a compression unit that compresses a refrigerant, an electric motor that drives the compression unit, a motor drive circuit that drives the electric motor, and a conductive member that is electrically connected to the motor drive circuit. And the motor wiring drawn from the electric motor. Further, the electric compressor accommodates a connection terminal that electrically connects the motor wiring and the conductive member, an insulating terminal accommodating member that internally accommodates the connection terminal, a compression unit, an electric motor, and a terminal accommodating member. It is equipped with a housing. The terminal accommodating member has a cluster block in which connection terminals are accommodated and a cover member that covers the entire cluster block. The cluster block has an opening for accommodating the connection terminal inside. The opening of the cluster block is closed by a cover member.

ところで、冷媒には、電動圧縮機内の摺動部位（例えば、圧縮部）の潤滑を良好とするための潤滑油が含まれている。潤滑油は、クラスタブロック内に侵入すると接続端子とハウジングとを導通させる可能性があるが、特許文献１に開示の電動圧縮機では、クラスタブロックの開口部はカバー部材によって塞がれているため、潤滑液を含んだ冷媒が開口部を介してクラスタブロック内に侵入することを抑制できる。よって、カバー部材によってクラスタブロックが覆われていない場合と比較して、接続端子とハウジングとの絶縁性を高めることができる。 By the way, the refrigerant contains a lubricating oil for improving the lubrication of the sliding portion (for example, the compression portion) in the electric compressor. When the lubricating oil enters the cluster block, it may conduct the connection terminal and the housing. However, in the electric compressor disclosed in Patent Document 1, the opening of the cluster block is closed by the cover member. , It is possible to prevent the refrigerant containing the lubricating liquid from entering the cluster block through the opening. Therefore, the insulation between the connection terminal and the housing can be improved as compared with the case where the cluster block is not covered by the cover member.

特開２０１３−２４５５５５号公報Japanese Unexamined Patent Publication No. 2013-245555

ところで、特許文献１では、クラスタブロック内に接続端子が収容されていることが説明及び図示されているものの、クラスタブロック内における接続端子の具体的な収容態様については開示されていない。導電部材を接続端子に接続する際、クラスタブロック内で接続端子が移動するなどして接続端子に導電部材をスムーズに接続できない虞がある。 By the way, in Patent Document 1, although it is described and illustrated that the connection terminal is accommodated in the cluster block, the specific accommodation mode of the connection terminal in the cluster block is not disclosed. When connecting the conductive member to the connection terminal, the connection terminal may move within the cluster block and the conductive member may not be smoothly connected to the connection terminal.

本発明は、上記課題を解決するためになされたものであり、その目的は、接続端子とハウジングとの絶縁を維持しつつ、接続端子に導電部材を接続しやすくできる電動圧縮機を提供することにある。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an electric compressor capable of easily connecting a conductive member to a connection terminal while maintaining insulation between the connection terminal and the housing. It is in.

上記問題点を解決するための電動圧縮機は、冷媒を圧縮する圧縮部と、前記圧縮部を駆動する電動モータと、前記電動モータを駆動するモータ駆動回路と、前記モータ駆動回路と電気的に接続された導電部材と、前記電動モータから引き出されたモータ配線と、前記モータ配線と前記導電部材とを電気的に接続する接続端子と、前記接続端子を内部に収容する絶縁性の端子収容部材と、前記圧縮部、前記電動モータ、及び前記端子収容部材を収容するハウジングと、を備えた電動圧縮機において、前記端子収容部材は、前記接続端子を保持する端子保持部材と、前記端子保持部材を収容するクラスタブロックとを備え、前記クラスタブロックは、前記端子保持部材を挿入するための収容孔を備え、前記端子保持部材は、前記接続端子を保持する保持部と、前記モータ配線が挿通されるとともに前記収
容孔の開口を閉塞する閉塞壁部とを有することを要旨とする。 An electric compressor for solving the above problems is electrically a compression unit that compresses a refrigerant, an electric motor that drives the compression unit, a motor drive circuit that drives the electric motor, and the motor drive circuit. An insulating terminal accommodating member that internally accommodates the connected conductive member, the motor wiring drawn from the electric motor, the connection terminal that electrically connects the motor wiring and the conductive member, and the connection terminal. In an electric compressor including the compression unit, the electric motor, and a housing for accommodating the terminal accommodating member, the terminal accommodating member includes a terminal holding member for holding the connection terminal and the terminal holding member. The cluster block is provided with a storage hole for inserting the terminal holding member, and the terminal holding member is inserted with a holding portion for holding the connection terminal and the motor wiring. The gist is that it also has a closing wall portion that closes the opening of the accommodation hole.

これによれば、クラスタブロックの収容孔の開口は、端子保持部材の閉塞壁部によって閉塞される。このため、潤滑液を含んだ冷媒が収容孔を介してクラスタブロック内に侵入することが抑制される。よって、接続端子とハウジングとの絶縁を維持できる。また、導電部材は、接続端子を保持している端子保持部材がクラスタブロックの収容孔に収容された後で、接続端子に接続される。端子保持部材の閉塞壁部は収容孔の開口を閉塞し、接続端子は端子保持部材の保持部によって保持されている。つまり、接続端子を保持する端子保持部材の一部が、接続端子を収容する隔壁の一部を構成する。よって、クラスタブロック内での接続端子の移動が規制され、接続端子に導電部材を接続しやすい。また、閉塞壁部にはモータ配線が挿通され、保持部には接続端子が保持されている。このため、閉塞壁部とモータ配線との位置関係、及び保持部と接続端子との位置関係を保ったまま、端子保持部材をクラスタブロックに収容できる。よって、接続端子とハウジングとの絶縁を維持しつつ、クラスタブロックに端子保持部材を組み付けやすくできる。 According to this, the opening of the accommodating hole of the cluster block is closed by the closing wall portion of the terminal holding member. Therefore, it is possible to prevent the refrigerant containing the lubricating liquid from entering the cluster block through the accommodating holes. Therefore, the insulation between the connection terminal and the housing can be maintained. Further, the conductive member is connected to the connection terminal after the terminal holding member holding the connection terminal is accommodated in the accommodating hole of the cluster block. The closing wall portion of the terminal holding member closes the opening of the accommodating hole, and the connection terminal is held by the holding portion of the terminal holding member. That is, a part of the terminal holding member holding the connection terminal constitutes a part of the partition wall accommodating the connection terminal. Therefore, the movement of the connection terminal in the cluster block is restricted, and it is easy to connect the conductive member to the connection terminal. Further, the motor wiring is inserted through the closed wall portion, and the connection terminal is held in the holding portion. Therefore, the terminal holding member can be accommodated in the cluster block while maintaining the positional relationship between the closed wall portion and the motor wiring and the positional relationship between the holding portion and the connection terminal. Therefore, it is possible to easily assemble the terminal holding member to the cluster block while maintaining the insulation between the connection terminal and the housing.

また、上記電動圧縮機について、前記閉塞壁部は、前記収容孔の内周面に嵌合される外周面と、前記外周面に凹設されるとともに前記モータ配線が挿通される挿通溝を有し、
前記保持部は、前記接続端子が挿入されるとともに前記挿通溝と連通しつつ同じ方向に開口する開口部を有するのが好ましい。 Further, with respect to the electric compressor, the closed wall portion has an outer peripheral surface fitted to the inner peripheral surface of the accommodating hole and an insertion groove recessed in the outer peripheral surface and through which the motor wiring is inserted. And
The holding portion preferably has an opening in which the connection terminal is inserted and opens in the same direction while communicating with the insertion groove.

これによれば、接続端子とモータ配線とを接続した後であっても、開口部から保持部に接続端子を挿入できるとともに、挿通溝から閉塞壁部にモータ配線を挿通できる。よって、端子保持部材に接続端子を保持させる際の作業性が良好になる。 According to this, even after connecting the connection terminal and the motor wiring, the connection terminal can be inserted from the opening into the holding portion, and the motor wiring can be inserted from the insertion groove into the closed wall portion. Therefore, workability when the terminal holding member holds the connection terminal is improved.

また、上記電動圧縮機について、前記収容孔と前記閉塞壁部における前記接続端子とは反対側の端面とによって囲まれる空間には、シール部材が設けられているのが好ましい。
これによれば、シール部材によって、収容孔と閉塞壁部との隙間がシールされる。このため、潤滑液を含んだ冷媒が、収容孔と閉塞壁部との隙間を介してクラスタブロック内に侵入することが抑制される。よって、接続端子とハウジングとの絶縁性をより高めることができる。 Further, with respect to the electric compressor, it is preferable that a sealing member is provided in a space surrounded by the accommodating hole and the end surface of the closed wall portion on the side opposite to the connection terminal.
According to this, the gap between the accommodating hole and the closing wall portion is sealed by the sealing member. Therefore, it is possible to prevent the refrigerant containing the lubricating liquid from entering the cluster block through the gap between the accommodating hole and the closed wall portion. Therefore, the insulation between the connection terminal and the housing can be further improved.

また、上記電動圧縮機について、前記クラスタブロックは、前記収容孔の開口側への前記端子保持部材の移動を規制する保持部材規制部を有するのが好ましい。
これによれば、保持部材規制部によってクラスタブロックに対する端子保持部材の移動が規制されるため、端子保持部材に保持されている接続端子についても、収容孔の開口側への移動が規制される。よって、接続端子に導電部材をより接続しやすくなる。 Further, with respect to the electric compressor, it is preferable that the cluster block has a holding member regulating portion that regulates the movement of the terminal holding member to the opening side of the accommodating hole.
According to this, since the movement of the terminal holding member with respect to the cluster block is restricted by the holding member regulating portion, the movement of the connection terminal held by the terminal holding member to the opening side of the accommodating hole is also restricted. Therefore, it becomes easier to connect the conductive member to the connection terminal.

また、上記電動圧縮機について、前記端子保持部材は、前記端子保持部材に対する前記接続端子の移動を規制する端子規制部を有するのが好ましい。
これによれば、端子規制部によって端子保持部材に対する接続端子の移動が規制されるため、端子保持部材から接続端子が外れることを抑制できる。 Further, with respect to the electric compressor, it is preferable that the terminal holding member has a terminal regulating portion that regulates the movement of the connecting terminal with respect to the terminal holding member.
According to this, since the movement of the connection terminal with respect to the terminal holding member is restricted by the terminal regulating portion, it is possible to prevent the connection terminal from being disconnected from the terminal holding member.

本発明によれば、接続端子とハウジングとの絶縁を維持しつつ、接続端子に導電部材を接続しやすくできる。 According to the present invention, it is possible to easily connect the conductive member to the connection terminal while maintaining the insulation between the connection terminal and the housing.

モータハウジング１２内には回転軸１６が収容されている。さらに、モータハウジング１２内には、冷媒を圧縮する圧縮部１７と、圧縮部１７を駆動する電動モータ１８とが収容されている。電動モータ１８は、回転軸１６を駆動させる。圧縮部１７は、回転軸１６が回転することにより駆動する。電動モータ１８は、圧縮部１７よりもモータハウジング１２の底壁１２１（図１の右側）寄りに配置されている。 The rotating shaft 16 is housed in the motor housing 12. Further, a compression unit 17 for compressing the refrigerant and an electric motor 18 for driving the compression unit 17 are housed in the motor housing 12. The electric motor 18 drives the rotating shaft 16. The compression unit 17 is driven by the rotation of the rotating shaft 16. The electric motor 18 is arranged closer to the bottom wall 121 (right side in FIG. 1) of the motor housing 12 than the compression unit 17.

モータハウジング１２内において、圧縮部１７と電動モータ１８との間には軸支部材１９が設けられている。軸支部材１９の中央部には、回転軸１６の一端部が挿通される挿通孔１９ａが形成されている。挿通孔１９ａと回転軸１６の一端部との間にはラジアルベアリング１６ａが設けられている。回転軸１６の一端部は、ラジアルベアリング１６ａを介して軸支部材１９に回転可能に支持されている。 In the motor housing 12, a shaft support member 19 is provided between the compression unit 17 and the electric motor 18. An insertion hole 19a through which one end of the rotating shaft 16 is inserted is formed in the central portion of the shaft support member 19. A radial bearing 16a is provided between the insertion hole 19a and one end of the rotating shaft 16. One end of the rotating shaft 16 is rotatably supported by the shaft support member 19 via a radial bearing 16a.

モータハウジング１２の底壁１２１には、軸受部１２１ａが凹設されている。軸受部１２１ａの内側には回転軸１６の他端部が挿入されている。軸受部１２１ａと回転軸１６の他端部との間にはラジアルベアリング１６ｂが設けられている。回転軸１６の他端部は、ラジアルベアリング１６ｂを介して軸受部１２１ａに回転可能に支持されている。 A bearing portion 121a is recessed in the bottom wall 121 of the motor housing 12. The other end of the rotating shaft 16 is inserted inside the bearing portion 121a. A radial bearing 16b is provided between the bearing portion 121a and the other end of the rotating shaft 16.

圧縮部１７は、モータハウジング１２内に固定された固定スクロール１７ａと、固定スクロール１７ａに対向配置された可動スクロール１７ｂとを備える。固定スクロール１７ａと可動スクロール１７ｂとの間には容積変更可能な圧縮室Ｓ３が区画形成されている。圧縮室Ｓ３の容積変更により圧縮された冷媒は、吐出室Ｓ１に吐出される。モータハウジング１２内、圧縮室Ｓ３、及び吐出室Ｓ１を流れる冷媒には、電動圧縮機１０内の摺動部位の潤滑（本実施形態では、固定スクロール１７と可動スクロール１７ｂとの潤滑）を良好とするための潤滑油が含まれている。 The compression unit 17 includes a fixed scroll 17a fixed in the motor housing 12 and a movable scroll 17b arranged to face the fixed scroll 17a. A volume-changeable compression chamber S3 is formed between the fixed scroll 17a and the movable scroll 17b. The refrigerant compressed by changing the volume of the compression chamber S3 is discharged to the discharge chamber S1. For the refrigerant flowing through the motor housing 12, the compression chamber S3, and the discharge chamber S1, lubrication of the sliding portion in the electric compressor 10 (in this embodiment, lubrication of the fixed scroll 17 and the movable scroll 17b) is good.

The insertion groove 69a communicates with the opening 66a. The tube member 28 and the two motor wirings 27 inserted through the tube member 28 are inserted into the motor wiring insertion portion 69 through the insertion groove 69a.

図４に示すように、第２接続部５２は、Ｘ方向において第１壁部６１の高段部６１ａの内面と第２壁部６２の内面との間に位置する。このため、端子保持部材６０に対して接続端子５０がＸ方向に移動しても、第２接続部５２が第１壁部６１の高段部６１ａ又は第２壁部６２に接触し、接続端子５０の更なる移動が規制される。よって、第１壁部６１の高段部６１ａ及び第２壁部６２は、Ｘ方向において端子保持部材６０に対する接続端子５０の移動を規制する第１端子規制部である。 As shown in FIG. 4, the second connecting portion 52 is located between the inner surface of the high step portion 61a of the first wall portion 61 and the inner surface of the second wall portion 62 in the X direction. Therefore, even if the connection terminal 50 moves in the X direction with respect to the terminal holding member 60, the second connection portion 52 comes into contact with the high step portion 61a or the second wall portion 62 of the first wall portion 61, and the connection terminal is connected. Further movement of 50 is restricted. Therefore, the high step portion 61a and the second wall portion 62 of the first wall portion 61 are first terminal restricting portions that regulate the movement of the connection terminal 50 with respect to the terminal holding member 60 in the X direction.

第２接続部５２は、Ｙ方向において第１壁部６１の第１接続壁６１ｄの内面と第４壁部６４の内面との間に位置する。このため、端子保持部材６０に対して接続端子５０がＹ方向に移動しても、第２接続部５２が第１壁部６１の第１接続壁６１ｄ又は第４壁部６４と接触し、接続端子５０の更なる移動が規制される。よって、第１壁部６１の第１接続壁６１ｄ及び第４壁部６４は、Ｙ方向において端子保持部材６０に対する接続端子５０の移動を規制する第２端子規制部である。 The second connecting portion 52 is located between the inner surface of the first connecting wall 61d of the first wall portion 61 and the inner surface of the fourth wall portion 64 in the Y direction. Therefore, even if the connection terminal 50 moves in the Y direction with respect to the terminal holding member 60, the second connection portion 52 contacts and connects with the first connection wall 61d or the fourth wall portion 64 of the first wall portion 61. Further movement of the terminal 50 is restricted. Therefore, the first connection wall 61d and the fourth wall portion 64 of the first wall portion 61 are second terminal regulation portions that regulate the movement of the connection terminal 50 with respect to the terminal holding member 60 in the Y direction.

図４に示すように、第２接続部５２の係止窓５２５には、第４壁部６４の突起６４ａが挿入されている。このため、端子保持部材６０に対して接続端子５０がＺ方向に移動しても、係止窓５２５の内側が突起６４ａに接触し、接続端子５０の更なる移動が規制される。よって、突起６４ａは、Ｚ方向において端子保持部材６０に対する接続端子５０の移動を規制する第３端子規制部である。 As shown in FIG. 4, the protrusion 64a of the fourth wall portion 64 is inserted into the locking window 525 of the second connecting portion 52. Therefore, even if the connection terminal 50 moves in the Z direction with respect to the terminal holding member 60, the inside of the locking window 525 comes into contact with the protrusion 64a, and further movement of the connection terminal 50 is restricted. Therefore, the protrusion 64a is a third terminal regulating portion that regulates the movement of the connecting terminal 50 with respect to the terminal holding member 60 in the Z direction.

各端子保持部材６０は、第４壁部６４がクラスタブロック７０の底壁７１側、第５壁部６５がクラスタブロック７０の収容孔７３の開口側に位置するように各クラスタブロック７０に収容されている。各端子保持部材６０の第１壁部６１は、導電部材挿通孔７５が形成された側壁７２の内面と対向している。第１壁部６１の高段部６１ａに形成された貫通部６７は、クラスタブロック７０の導電部材挿通孔７５と連通している。各端子保持部材６０の第２壁部６２は、凹部７６が形成された側壁７２の内面と対向している。第２壁部６２の爪部６２ｂの先端側部位は、クラスタブロック７０の凹部７６に収容されている。このため、端子保持部材６０が収容孔７３の開口側に移動しても、爪部６２ｂの先端部が凹部７６の内壁と接触することで、端子保持部材６０の更なる移動が規制される。よって、クラスタブロック７０の凹部７６は、Ｙ方向においてクラスタブロック７０に対する端子保持部材６０の移動を規制する保持部材規制部である。 Each terminal holding member 60 is accommodated in each cluster block 70 so that the fourth wall portion 64 is located on the bottom wall 71 side of the cluster block 70 and the fifth wall portion 65 is located on the opening side of the accommodating hole 73 of the cluster block 70. ing. The first wall portion 61 of each terminal holding member 60 faces the inner surface of the side wall 72 in which the conductive member insertion hole 75 is formed. The through portion 67 formed in the high step portion 61a of the first wall portion 61 communicates with the conductive member insertion hole 75 of the cluster block 70. The second wall portion 62 of each terminal holding member 60 faces the inner surface of the side wall 72 in which the recess 76 is formed. The tip end side portion of the claw portion 62b of the second wall portion 62 is housed in the recess 76 of the cluster block 70. Therefore, even if the terminal holding member 60 moves to the opening side of the accommodating hole 73, the tip of the claw portion 62b comes into contact with the inner wall of the recess 76, so that further movement of the terminal holding member 60 is restricted. Therefore, the recess 76 of the cluster block 70 is a holding member regulating portion that regulates the movement of the terminal holding member 60 with respect to the cluster block 70 in the Y direction.

各端子保持部材６０の第４壁部６４は、クラスタブロック７０の底壁７１の内面と対向する。各端子保持部材６０の第５壁部６５は、外周面６５ａがクラスタブロック７０の各収容孔７３の開口に嵌合されることで、各収容孔７３の開口を閉塞している。よって、第５壁部６５は、閉塞壁部である。第５壁部６５における第４壁部６４とは反対側の端面６５ｂは、Ｙ方向においてクラスタブロック７０の側壁７２の先端面よりも底壁７１側に位置している。 The fourth wall portion 64 of each terminal holding member 60 faces the inner surface of the bottom wall 71 of the cluster block 70. The fifth wall portion 65 of each terminal holding member 60 closes the opening of each accommodating hole 73 by fitting the outer peripheral surface 65a into the opening of each accommodating hole 73 of the cluster block 70. Therefore, the fifth wall portion 65 is a closed wall portion. The end surface 65b of the fifth wall portion 65 opposite to the fourth wall portion 64 is located on the bottom wall 71 side of the front end surface of the side wall 72 of the cluster block 70 in the Y direction.

A member 91 is provided. The first seal member 91 of the present embodiment is an adhesive made of resin. Each terminal holding member 60 and the cluster block 70 are adhered to each other by a first seal member 91. Further, between the inner surface of the side wall 72 and the partition wall 74 forming each accommodating hole 73 and the outer edge portion of the fifth wall portion 65, and between the motor wiring insertion portion 69 of the fifth wall portion 65 and the tube member 28. , It is sealed by the first seal member 91.

The gap between the inner peripheral surface of each guide portion 72b and each conductive member 32 is sealed by the second sealing member 92.

次に、コネクタ４０の組み付け方法について詳述する。
まず、接続端子５０の第１接続部５１に２本のモータ配線２７を接続する。これにより、接続端子５０は、モータ配線２７と電気的に接続される。また、チューブ部材２８の第１接続部５１側の端部、及びモータ配線２７の第１接続部５１側の一部をかしめてかしめ部５３を形成する。 Next, the method of assembling the connector 40 will be described in detail.
First, two motor wirings 27 are connected to the first connection portion 51 of the connection terminal 50. As a result, the connection terminal 50 is electrically connected to the motor wiring 27. Further, the end portion of the tube member 28 on the first connection portion 51 side and a part of the motor wiring 27 on the first connection portion 51 side are crimped to form the caulking portion 53.

次に、図６（ａ）〜図６（ｃ）に示すように、接続端子５０を、Ｚ方向の一方側（第３壁部６３とは反対側）から端子保持部材６０の保持部６６に挿入するとともに、チューブ部材２８を第５壁部６５の挿通溝６９ａからモータ配線挿通部６９に挿入する。このとき、図６（ａ）に示すように、各接続端子５０において、第２接続部５２は、第１接続部５１よりも先に保持部６６に挿入される。第２接続部５２の係止窓５２５には、端子保持部材６０の第４壁部６４の突起６４ａが挿入される。その後、図６（ｂ）に示すように、各接続端子５０の第１接続部５１が保持部６６に挿入され、チューブ部材２８がモータ配線挿通部６９に挿入される。これにより、図６（ｃ）に示すように、接続端子５０は、端子保持部材６０の保持部６６に保持され、チューブ部材２８は、モータ配線挿通部６９に挿通された状態となる。また、端子保持部材６０の第３壁部６３の貫通部６７は、接続端子５０の第２接続部５２の四角筒の内側と連通する。 Next, as shown in FIGS. 6A to 6C, the connection terminal 50 is connected to the holding portion 66 of the terminal holding member 60 from one side in the Z direction (the side opposite to the third wall portion 63). At the same time, the tube member 28 is inserted into the motor wiring insertion portion 69 from the insertion groove 69a of the fifth wall portion 65. At this time, as shown in FIG. 6A, at each connection terminal 50, the second connection portion 52 is inserted into the holding portion 66 before the first connection portion 51. The protrusion 64a of the fourth wall portion 64 of the terminal holding member 60 is inserted into the locking window 525 of the second connecting portion 52. After that, as shown in FIG. 6B, the first connection portion 51 of each connection terminal 50 is inserted into the holding portion 66, and the tube member 28 is inserted into the motor wiring insertion portion 69. As a result, as shown in FIG. 6C, the connection terminal 50 is held by the holding portion 66 of the terminal holding member 60, and the tube member 28 is inserted into the motor wiring insertion portion 69. Further, the penetrating portion 67 of the third wall portion 63 of the terminal holding member 60 communicates with the inside of the square cylinder of the second connecting portion 52 of the connecting terminal 50.

次に、接続端子５０を保持する端子保持部材６０をクラスタブロック７０の収容孔７３に挿入する。このとき、第２壁部６２の爪部６２ｂは、クラスタブロック７０の側壁７２によって第２接続部５２側に押圧される。そして、端子保持部材６０が収容孔７３に完全に収容されると、第２壁部６２の爪部６２ｂは、クラスタブロック７０の凹部７６と対向することで押圧された状態から原形状に復帰するとともに凹部７６に収容される。また、端子保持部材６０の第３壁部６３の貫通部６７、及び接続端子５０の第２接続部５２の四角筒の内側は、クラスタブロック７０の導電部材挿通孔７５と連通する。さらに、端子保持部材６０の第５壁部６５は、クラスタブロック７０の収容孔７３の開口に嵌合されて収容孔７３の開口を閉塞する。 Next, the terminal holding member 60 that holds the connection terminal 50 is inserted into the accommodating hole 73 of the cluster block 70. At this time, the claw portion 62b of the second wall portion 62 is pressed toward the second connecting portion 52 by the side wall 72 of the cluster block 70. When the terminal holding member 60 is completely accommodated in the accommodating hole 73, the claw portion 62b of the second wall portion 62 returns to its original shape from the pressed state by facing the recess 76 of the cluster block 70. It is housed in the recess 76 together with. Further, the through portion 67 of the third wall portion 63 of the terminal holding member 60 and the inside of the square cylinder of the second connecting portion 52 of the connection terminal 50 communicate with the conductive member insertion hole 75 of the cluster block 70. Further, the fifth wall portion 65 of the terminal holding member 60 is fitted into the opening of the accommodating hole 73 of the cluster block 70 to close the opening of the accommodating hole 73.

次に、収容孔７３の開口と第５壁部６５の端面６５ｂとによって囲まれた空間に接着剤を充填することで第１シール部材９１を設ける。また、各導電部材３２の他端を、クラスタブロック７０の導電部材挿通孔７５及び端子保持部材６０の貫通部６７を介して接続端子５０の第２接続部５２の四角筒の内側に挿入する。これにより、接続端子５０は、導電部材３２と電気的に接続される。そして、各ガイド部７２ｂの内周面と導電部材３２との間に第２シール部材９２を取り付ける。 Next, the first seal member 91 is provided by filling the space surrounded by the opening of the accommodating hole 73 and the end surface 65b of the fifth wall portion 65 with an adhesive. Further, the other end of each conductive member 32 is inserted into the inside of the square cylinder of the second connecting portion 52 of the connecting terminal 50 via the conductive member insertion hole 75 of the cluster block 70 and the penetrating portion 67 of the terminal holding member 60. As a result, the connection terminal 50 is electrically connected to the conductive member 32. Then, the second seal member 92 is attached between the inner peripheral surface of each guide portion 72b and the conductive member 32.

上記構成の電動圧縮機１０では、モータ駆動回路２０から、各導電部材３２、各接続端子５０、及び各モータ配線２７を介して電動モータ１８に電力が供給されると、電動モータ１８が駆動し、電動モータ１８の駆動に伴う回転軸１６の回転によって、圧縮部１７が駆動して冷媒が圧縮部１７により圧縮される。 In the electric compressor 10 having the above configuration, when electric power is supplied from the motor drive circuit 20 to the electric motor 18 via each conductive member 32, each connection terminal 50, and each motor wiring 27, the electric motor 18 is driven. The rotation of the rotating shaft 16 accompanying the driving of the electric motor 18 drives the compression unit 17 and compresses the refrigerant by the compression unit 17.

本実施形態の作用及び効果について説明する。
（１）各収容孔７３の開口は、各端子保持部材６０の第５壁部６５によって閉塞されている。このため、潤滑液を含んだ冷媒が各収容孔７３を介してクラスタブロック７０内に侵入することが抑制される。よって、接続端子５０とモータハウジング１２との絶縁を維持できる。また、各導電部材３２は、各接続端子５０を保持している各端子保持部材６０がクラスタブロック７０の各収容孔７３に収容された後で、接続端子５０に接続される。
各端子保持部材６０の第５壁部６５は、各収容孔７３の開口を閉塞し、各接続端子５０は、各端子保持部材６０の保持部６６によって保持されている。つまり、各接続端子５０を保持する各端子保持部材６０の一部が接続端子５０を収容する隔壁の一部を構成している。よって、クラスタブロック７０内での各接続端子５０の移動が規制され、各接続端子５０に各導電部材３２を接続しやすい。 The operation and effect of this embodiment will be described.
(1) The opening of each accommodating hole 73 is closed by the fifth wall portion 65 of each terminal holding member 60. Therefore, it is possible to prevent the refrigerant containing the lubricating liquid from entering the cluster block 70 through each of the accommodating holes 73. Therefore, the insulation between the connection terminal 50 and the motor housing 12 can be maintained. Further, each conductive member 32 is connected to the connection terminal 50 after each terminal holding member 60 holding each connection terminal 50 is accommodated in each accommodation hole 73 of the cluster block 70.
The fifth wall portion 65 of each terminal holding member 60 closes the opening of each accommodating hole 73, and each connection terminal 50 is held by the holding portion 66 of each terminal holding member 60. That is, a part of each terminal holding member 60 holding each connection terminal 50 constitutes a part of a partition wall accommodating the connection terminal 50. Therefore, the movement of each connection terminal 50 in the cluster block 70 is restricted, and it is easy to connect each conductive member 32 to each connection terminal 50.

また、第５壁部６５にはモータ配線２７が挿通され、保持部６６には接続端子５０が保持されている。このため、第５壁部６５とモータ配線２７との位置関係、及び保持部６６と接続端子５０との位置関係を保ったまま、端子保持部材６０をクラスタブロック７０に収容できる。よって、接続端子５０とモータハウジング１２との絶縁を維持しつつ、クラスタブロック７０に端子保持部材６０を組み付けやすくできる。 Further, the motor wiring 27 is inserted through the fifth wall portion 65, and the connection terminal 50 is held in the holding portion 66. Therefore, the terminal holding member 60 can be accommodated in the cluster block 70 while maintaining the positional relationship between the fifth wall portion 65 and the motor wiring 27 and the positional relationship between the holding portion 66 and the connection terminal 50. Therefore, the terminal holding member 60 can be easily assembled to the cluster block 70 while maintaining the insulation between the connection terminal 50 and the motor housing 12.

（２）各端子保持部材６０の保持部６６は、接続端子５０が挿入される開口部６６ａを有している。また、各端子保持部材６０の第５壁部６５は、モータ配線２７が挿通される挿通溝６９ａを有している。開口部６６ａと挿通溝６９ａは、連通しつつ同じ方向に開口している。このため、接続端子５０とモータ配線２７とを接続した後であっても、開口部６６ａ及び挿通溝６９ａから保持部６６及びモータ配線挿通部６９に接続端子５０及びモータ配線２７を挿入できる。よって、各端子保持部材６０に各接続端子５０を保持させる際の作業性が良好になる。 (2) The holding portion 66 of each terminal holding member 60 has an opening 66a into which the connection terminal 50 is inserted. Further, the fifth wall portion 65 of each terminal holding member 60 has an insertion groove 69a through which the motor wiring 27 is inserted. The opening 66a and the insertion groove 69a are open in the same direction while communicating with each other. Therefore, even after the connection terminal 50 and the motor wiring 27 are connected, the connection terminal 50 and the motor wiring 27 can be inserted from the opening 66a and the insertion groove 69a into the holding portion 66 and the motor wiring insertion portion 69. Therefore, workability when each terminal holding member 60 holds each connection terminal 50 is improved.

（３）各クラスタブロック７０の収容孔７３の開口と各端子保持部材６０の第５壁部６５の端面６５ｂとによって囲まれる空間には、第１シール部材９１である接着剤が充填されている。第１シール部材９１によって、収容孔７３の開口と第５壁部６５の外縁部との隙間がシールされる。このため、潤滑液を含んだ冷媒が、収容孔７３の開口と第５壁部６５との隙間を介してクラスタブロック７０内に侵入することが抑制される。よって、接続端子５０とモータハウジング１２との絶縁性をより高めることができる。 (3) The space surrounded by the opening of the accommodating hole 73 of each cluster block 70 and the end surface 65b of the fifth wall portion 65 of each terminal holding member 60 is filled with the adhesive which is the first sealing member 91. .. The gap between the opening of the accommodating hole 73 and the outer edge of the fifth wall portion 65 is sealed by the first sealing member 91. Therefore, it is possible to prevent the refrigerant containing the lubricating liquid from entering the cluster block 70 through the gap between the opening of the accommodating hole 73 and the fifth wall portion 65. Therefore, the insulation between the connection terminal 50 and the motor housing 12 can be further improved.

（４）各クラスタブロック７０の収容孔７３の開口と各端子保持部材６０の第５壁部６５の端面６５ｂとによって囲まれる空間には、第１シール部材９１である接着剤が充填されている。第１シール部材９１によって、チューブ部材２８とモータ配線挿通部６９との隙間がシールされる。このため、潤滑液を含んだ冷媒が、チューブ部材２８と第５壁部６５のモータ配線挿通部６９との隙間を介してクラスタブロック７０内に侵入することが抑制される。よって、接続端子５０とモータハウジング１２との絶縁性をより高めることができる。 (4) The space surrounded by the opening of the accommodating hole 73 of each cluster block 70 and the end surface 65b of the fifth wall portion 65 of each terminal holding member 60 is filled with the adhesive which is the first sealing member 91. .. The first seal member 91 seals the gap between the tube member 28 and the motor wiring insertion portion 69. Therefore, it is possible to prevent the refrigerant containing the lubricating liquid from entering the cluster block 70 through the gap between the tube member 28 and the motor wiring insertion portion 69 of the fifth wall portion 65. Therefore, the insulation between the connection terminal 50 and the motor housing 12 can be further improved.

（５）クラスタブロック７０の導電部材挿通孔７５の一部である各ガイド部７２ｂの内周面と各導電部材３２との間には、第２シール部材９２であるゴム栓が取り付けられている。第２シール部材９２によって、各ガイド部７２ｂの内周面と各導電部材３２との隙間がシールされる。このため、潤滑液を含んだ冷媒が、各ガイド部７２ｂの内周面と各導電部材３２との隙間を介してクラスタブロック７０内に侵入することが抑制される。よって、接続端子５０とモータハウジング１２との絶縁性をより高めることができる。 (5) A rubber stopper, which is a second seal member 92, is attached between the inner peripheral surface of each guide portion 72b, which is a part of the conductive member insertion hole 75 of the cluster block 70, and each conductive member 32. .. The gap between the inner peripheral surface of each guide portion 72b and each conductive member 32 is sealed by the second sealing member 92. Therefore, it is possible to prevent the refrigerant containing the lubricating liquid from entering the cluster block 70 through the gap between the inner peripheral surface of each guide portion 72b and each conductive member 32. Therefore, the insulation between the connection terminal 50 and the motor housing 12 can be further improved.

（６）端子保持部材６０の第２壁部６２は、爪部６２ｂを備える。爪部６２ｂは、クラスタブロック７０の凹部７６に収容されている。このため、端子保持部材６０が収容孔７３の開口側に移動しても、爪部６２ｂの先端部が凹部７６の内壁に接触し、クラスタブロック７０に対する端子保持部材６０の移動が規制される。よって、各端子保持部材６０に保持されている各接続端子５０についても収容孔７３の開口側への移動が規制され、各接続端子５０に各導電部材３２をより接続しやすくなる。 (6) The second wall portion 62 of the terminal holding member 60 includes a claw portion 62b. The claw portion 62b is housed in the recess 76 of the cluster block 70. Therefore, even if the terminal holding member 60 moves to the opening side of the accommodating hole 73, the tip end portion of the claw portion 62b comes into contact with the inner wall of the recess 76, and the movement of the terminal holding member 60 with respect to the cluster block 70 is restricted. Therefore, the movement of each connection terminal 50 held by each terminal holding member 60 to the opening side of the accommodating hole 73 is restricted, and each conductive member 32 can be more easily connected to each connection terminal 50.

（７）各接続端子５０の第２接続部５２は、各端子保持部材６０の第１壁部６１の高段
部６１ａと第２壁部６２とによってＸ方向に挟まれている。第１壁部６１及び第２壁部６２は、端子保持部材６０に対する接続端子５０のＸ方向への移動を規制する。よって、各端子保持部材６０から各接続端子５０が外れることを抑制できる。 (7) The second connection portion 52 of each connection terminal 50 is sandwiched in the X direction by the high step portion 61a and the second wall portion 62 of the first wall portion 61 of each terminal holding member 60. The first wall portion 61 and the second wall portion 62 restrict the movement of the connection terminal 50 with respect to the terminal holding member 60 in the X direction. Therefore, it is possible to prevent each connection terminal 50 from being detached from each terminal holding member 60.

（８）各接続端子５０の第２接続部５２は、各端子保持部材６０の第１壁部６１の第１接続壁６１ｄと第４壁部６４とによってＹ方向に挟まれている。第１壁部６１の第１接続壁６１ｄ及び第４壁部６４は、端子保持部材６０に対する接続端子５０のＹ方向への移動を規制する。よって、各端子保持部材６０から各接続端子５０が外れることを抑制できる。 (8) The second connection portion 52 of each connection terminal 50 is sandwiched in the Y direction by the first connection wall 61d and the fourth wall portion 64 of the first wall portion 61 of each terminal holding member 60. The first connection wall 61d and the fourth wall portion 64 of the first wall portion 61 regulate the movement of the connection terminal 50 with respect to the terminal holding member 60 in the Y direction. Therefore, it is possible to prevent each connection terminal 50 from being detached from each terminal holding member 60.

（９）各接続端子５０の第２接続部５２の係止窓５２５には、各端子保持部材６０の第４壁部６４の突起６４ａが挿入されている。突起６４ａは、端子保持部材６０に対する接続端子５０のＸ方向及びＺ方向への移動を規制する。よって、各端子保持部材６０から各接続端子５０が外れることを抑制できる。 (9) A protrusion 64a of the fourth wall portion 64 of each terminal holding member 60 is inserted into the locking window 525 of the second connection portion 52 of each connection terminal 50. The protrusion 64a regulates the movement of the connection terminal 50 with respect to the terminal holding member 60 in the X direction and the Z direction. Therefore, it is possible to prevent each connection terminal 50 from being detached from each terminal holding member 60.

例えば、端子保持部材６０の第３壁部６３に保持部６６の開口部６６ａ側に突出する突起を形成するとともに、接続端子５０の第２接続部５２に長側壁５２１をＺ方向に貫通する係止窓を形成してもよい。接続端子５０の第２接続部５２の係止窓には、端子保持部材６０の第３壁部６３の突起が挿入される。これにより、端子保持部材６０に対する接続端子５０のＸ方向及びＹ方向への移動を規制できる。また、端子保持部材６０の第４壁部６４の突起の代わりに凹部を形成するとともに、接続端子５０の第２接続部５２の係止窓の代わりに爪部を形成してもよい。第２接続部５２の爪部は、第４壁部６４の凹部に収容される。これにより、端子保持部材６０に対する接続端子５０のＺ方向への移動を規制できる。 For example, the third wall portion 63 of the terminal holding member 60 is formed with a protrusion protruding toward the opening 66a of the holding portion 66, and the second connecting portion 52 of the connecting terminal 50 is engaged with penetrating the long side wall 521 in the Z direction. A stop window may be formed. A protrusion of the third wall portion 63 of the terminal holding member 60 is inserted into the locking window of the second connection portion 52 of the connection terminal 50.
