Description

本発明は、回転電機に関する。 The present invention relates to a rotary electric machine.

従来、端子台を備えた回転電機が知られている（たとえば、特許文献１参照）。 Conventionally, a rotary electric machine provided with a terminal block is known (see, for example, Patent Document 1).

上記特許文献１には、三相回転電機に設けられる端子台が開示されている。この端子台は、三相回転電機と、インバータ回路とを接続する中継部を備える。具体的には、中継部は、三相回転電機に設けられる各相の巻線のケーブル（コイル部）と、インバータ回路に設けられる各相のケーブルとを接続することにより、三相回転電機とインバータ回路とを接続するように設けられている。また、中継部は、端子台に固定される固定部を有している。 The above-mentioned Patent Document 1 discloses a terminal block provided in a three-phase rotary electric machine. This terminal block includes a relay unit that connects a three-phase rotary electric machine and an inverter circuit. Specifically, the relay unit can be connected to the three-phase rotary electric machine by connecting the winding cable (coil part) of each phase provided in the three-phase rotary electric machine and the cable of each phase provided in the inverter circuit. It is provided so as to connect to an inverter circuit. Further, the relay portion has a fixing portion fixed to the terminal block.

特開２０１０−１１６５６号公報Japanese Unexamined Patent Publication No. 2010-11656

しかしながら、上記特許文献１に記載の回転電機では、中継部は、固定部により端子台に固定されている。ここで、端子台と三相回転電機との離間距離が大きい場合等において、中継部の長さを大きくする必要がある。この場合、回転電機の振動に起因して中継部に生じる振動が比較的大きくなるため、中継部から三相回転電機に加わる負荷が大きくなるという問題点がある。 However, in the rotary electric machine described in Patent Document 1, the relay portion is fixed to the terminal block by the fixing portion. Here, when the separation distance between the terminal block and the three-phase rotary electric machine is large, it is necessary to increase the length of the relay portion. In this case, since the vibration generated in the relay portion due to the vibration of the rotary electric machine becomes relatively large, there is a problem that the load applied from the relay portion to the three-phase rotary electric machine becomes large.

この発明は、上記のような課題を解決するためになされたものであり、この発明の１つの目的は、中継部材の長さが大きくなった場合でも、中継部材から回転電機に加わる負荷が大きくなるのを防止することが可能な回転電機を提供することである。 The present invention has been made to solve the above-mentioned problems, and one object of the present invention is that even when the length of the relay member is increased, the load applied from the relay member to the rotary electric machine is large. It is to provide a rotary electric machine which can prevent the occurrence.

上記目的を達成するために、この発明の一の局面における回転電機は、コイル部が配置されているステータと、ステータが収容されているケース部と、外部から電力が供給される端子台と、コイル部に接続されるステータ接続端子部と、端子台に設けられる端子に接続される端子台接続端子部とを含み、端子台とコイル部とを電気的に接続する中継部材と、を備え、中継部材は、中継部材をケース部に固定するための中継部材固定部を含む。 In order to achieve the above object, the rotary electric machine in one aspect of the present invention includes a stator in which a coil portion is arranged, a case portion in which the stator is housed, and a terminal block to which power is supplied from the outside. It includes a stator connection terminal portion connected to the coil portion and a terminal block connection terminal portion connected to a terminal provided on the terminal block, and includes a relay member for electrically connecting the terminal block and the coil portion. The relay member includes a relay member fixing portion for fixing the relay member to the case portion.

この発明の一の局面による回転電機では、上記のように、中継部材は、中継部材をケース部に固定するための中継部材固定部を含む。これにより、中継部材は、端子台接続端子部により端子台に接続されていることに加えて、中継部材固定部によってケース部に固定されるので、中継部材が端子台にのみ固定されている場合に比べて中継部材を安定して固定することができる。その結果、中継部材の長さが大きくなった場合でも、中継部材の振動を低減することができるので、中継部材から回転電機に加わる負荷が大きくなるのを防止することができる。また、ケース部は、端子台に比べて一般的に剛性が高いので、中継部材がケース部に固定されていることによって、中継部材の振動をより低減することができる。 In the rotary electric machine according to one aspect of the present invention, as described above, the relay member includes a relay member fixing portion for fixing the relay member to the case portion. As a result, in addition to being connected to the terminal block by the terminal block connection terminal section, the relay member is fixed to the case portion by the relay member fixing portion, so that the relay member is fixed only to the terminal block. The relay member can be fixed more stably than the above. As a result, even when the length of the relay member is increased, the vibration of the relay member can be reduced, so that it is possible to prevent the load applied from the relay member to the rotary electric machine to be increased. Further, since the case portion is generally more rigid than the terminal block, the vibration of the relay member can be further reduced by fixing the relay member to the case portion.

本発明によれば、中継部材の長さが大きくなった場合でも、中継部材から回転電機に加わる負荷が大きくなるのを防止することができる。 According to the present invention, even when the length of the relay member is increased, it is possible to prevent the load applied from the relay member to the rotary electric machine to be increased.

In this embodiment, the following effects can be obtained.

本実施形態では、上記のように、中継部材（６０）は、中継部材（６０）をケース部（４０）に固定するための中継部材固定部（６４）を含む。これにより、中継部材（６０）は、端子台接続端子部（６２）により端子台（５０）に接続されていることに加えて、中継部材固定部（６４）によってケース部（４０）に固定されるので、中継部材（６０）が端子台（５０）にのみ固定されている場合に比べて中継部材（６０）を安定して固定することができる。その結果、中継部材（６０）の長さが大きくなった場合でも、中継部材（６０）の振動を低減することができるので、中継部材（６０）から回転電機（１２０）に加わる負荷が大きくなるのを防止することができる。また、ケース部（４０）は、端子台（５０）に比べて一般的に剛性が高いので、中継部材（６０）がケース部（４０）に固定されていることによって、中継部材（６０）の振動をより低減することができる。 In the present embodiment, as described above, the relay member (60) includes a relay member fixing portion (64) for fixing the relay member (60) to the case portion (40). As a result, the relay member (60) is fixed to the case portion (40) by the relay member fixing portion (64) in addition to being connected to the terminal block (50) by the terminal block connecting terminal portion (62). Therefore, the relay member (60) can be stably fixed as compared with the case where the relay member (60) is fixed only to the terminal block (50). As a result, even when the length of the relay member (60) is increased, the vibration of the relay member (60) can be reduced, so that the load applied from the relay member (60) to the rotary electric machine (120) is increased. Can be prevented. Further, since the case portion (40) is generally more rigid than the terminal block (50), the relay member (60) is fixed to the case portion (40), so that the relay member (60) has a higher rigidity. Vibration can be further reduced.

また、本実施形態では、上記のように、ケース部（４０）は、ステータ（１００）の軸方向から見て、ステータ（１００）を取り囲むように設けられる外壁部（４１）と、ステータ（１００）と外壁部（４１）との間に設けられ、中継部材（６０）の中継部材固定部（６４）と接続されるケース固定部（４１ｃ）と、を含む。このように構成すれば、中継部材固定部（６４）が外壁部（４１）と接続される場合に比べて、ステータ（１００）に対してより近い位置において中継部材（６０）を固定することができるので、中継部材（６０）の振動をより一層低減することができる。 Further, in the present embodiment, as described above, the case portion (40) includes the outer wall portion (41) provided so as to surround the stator (100) and the stator (100) when viewed from the axial direction of the stator (100). ) And the case fixing portion (41c) provided between the outer wall portion (41) and connected to the relay member fixing portion (64) of the relay member (60). With this configuration, the relay member (60) can be fixed at a position closer to the stator (100) than when the relay member fixing portion (64) is connected to the outer wall portion (41). Therefore, the vibration of the relay member (60) can be further reduced.

また、本実施形態では、上記のように、ケース部（４０）のケース固定部（４１ｃ）は、ケース部（４０）の外壁部（４１）と一体的に形成されている。このように構成すれば、ケース固定部（４１ｃ）と外壁部（４１）とが別個に設けられている場合に比べて、部品点数を低減することができる。また、ケース固定部（４１ｃ）が独立して設けられる場合に比べて、ケース固定部（４１ｃ）の剛性（機械的強度）をより高くすることができる。 Further, in the present embodiment, as described above, the case fixing portion (41c) of the case portion (40) is integrally formed with the outer wall portion (41) of the case portion (40). With this configuration, the number of parts can be reduced as compared with the case where the case fixing portion (41c) and the outer wall portion (41) are separately provided. Further, the rigidity (mechanical strength) of the case fixing portion (41c) can be made higher than that in the case where the case fixing portion (41c) is provided independently.

また、本実施形態では、上記のように、中継部材固定部（６４）は、第１固定部（６４ａ）と、第１固定部（６４ａ）とは別個に設けられる第２固定部（６４ｂ）とを含む。このように構成すれば、中継部材（６０）を複数の固定部により固定することができるので、中継部材（６０）を単一の固定部により固定する場合に比べて、中継部材（６０）の振動をより軽減することができる。 Further, in the present embodiment, as described above, the relay member fixing portion (64) is provided separately from the first fixing portion (64a) and the first fixing portion (64a). And include. With this configuration, the relay member (60) can be fixed by a plurality of fixing portions, so that the relay member (60) can be fixed as compared with the case where the relay member (60) is fixed by a single fixing portion. Vibration can be further reduced.

As a result, the relay member (60) can be fixed in a well-balanced manner.

また、本実施形態では、上記のように、第１固定部（６４ａ）および第２固定部（６４ｂ）は、樹脂製保持部（６３）から互いに反対側に突出するように設けられている。このように構成すれば、第１固定部（６４ａ）および第２固定部（６４ｂ）により、樹脂製保持部（６３）を挟んで両側から中継部（６０）を固定することができる。その結果、中継部（６０）をより安定して固定することができる。また、第１固定部（６４ａ）および第２固定部（６４ｂ）が互いに同じ方向に突出するように設けられる場合に比べて、第１固定部（６４ａ）と第２固定部（６４ｂ）との離間距離を容易に大きくすることができる。これにより、樹脂製保持部（６３）を大型化せずに、第１固定部（６４ａ）と第２固定部（６４ｂ）との離間距離を容易に大きくすることができる。その結果、樹脂製保持部（６３）の大型化を防止しながら、第１固定部（６４ａ）と第２固定部（６４ｂ）との離間距離を大きくすることにより中継部材（６０）の振動を軽減することができる。 Further, in the present embodiment, as described above, the first fixing portion (64a) and the second fixing portion (64b) are provided so as to project from the resin holding portion (63) on opposite sides to each other. With this configuration, the relay portion (60) can be fixed from both sides of the resin holding portion (63) by the first fixing portion (64a) and the second fixing portion (64b). As a result, the relay unit (60) can be fixed more stably. Further, as compared with the case where the first fixed portion (64a) and the second fixed portion (64b) are provided so as to project in the same direction from each other, the first fixed portion (64a) and the second fixed portion (64b) are The separation distance can be easily increased. As a result, the separation distance between the first fixing portion (64a) and the second fixing portion (64b) can be easily increased without increasing the size of the resin holding portion (63). As a result, the relay member (60) is vibrated by increasing the separation distance between the first fixing portion (64a) and the second fixing portion (64b) while preventing the resin holding portion (63) from becoming larger. It can be mitigated.

With this configuration, the distance between the first fixed portion (64a) and the second fixed portion (64b) in a predetermined direction (A direction) can be increased. As a result, the relay member (60) can be stably fixed as compared with the case where the separation distance between the first fixing portion (64a) and the second fixing portion (64b) is relatively small. Further, since the first fixing portion (64a) is not provided between the stator connecting terminal portions (61), the insulation distance between the first fixing portion (64a) and the stator connecting terminal portion (61) can be easily secured. be able to.
