In addition, when the crimp terminal 25 is inserted between the collar 7 and the bus bar 20, the crimp terminal 25 is passed through each terminal 6 after the collar 7, and when the crimp terminal 25 is inserted between the bus bar 20 and the terminal fixing nut 8. In this case, the crimp terminal 25 may be passed through each terminal 6 after the bus bar 20.

次に、絶縁距離について説明する。絶縁距離とは、短絡する可能性がある導電部から別の導電部までの最短距離のことである。絶縁距離には、空間距離と沿面距離の２種類の距離が存在する。空間距離は、２つの導電部間の空間的な最短距離であり、沿面距離は、２つの導電部間に設けられた絶縁体の外形に沿った最短距離である。 Next, the insulation distance will be explained. Insulation distance is the shortest distance from one conductive part to another that can cause a short circuit. There are two types of insulation distances: spatial distance and creepage distance. The spatial distance is the shortest spatial distance between two conductive parts, and the creepage distance is the shortest distance along the outline of the insulator provided between the two conductive parts.

図５は、導電部３０間の空間距離を説明する図である。図５（ａ）は平らな絶縁板３１を用いる場合、図５（ｂ）は導電部３０間に導電部３０の高さよりも高い凸部が設けられた絶縁板３２を用いる場合、図５（ｃ）は導電部３０間に凹部が設けられた絶縁板３３を用いる場合を示す。図５（ａ）～（ｃ）において、破線で示した部分の長さが導電部３０間の空間距離を示している。 FIG. 5 is a diagram illustrating the spatial distance between the conductive parts 30. FIG. 5(a) shows the case where a flat insulating plate 31 is used, and FIG. c) shows a case where an insulating plate 33 in which a recess is provided between the conductive parts 30 is used. In FIGS. 5(a) to 5(c), the length of the portion indicated by the broken line indicates the spatial distance between the conductive parts 30.

図５（ａ）に示すように、平らな絶縁板３１を用いる場合は、導電部３０間の空間距離は絶縁板３１の表面に沿った長さとなる。図５（ｂ）に示すように、凸部が設けられた絶縁板３２を用いる場合は、導電部３０間の空間距離は、一方の導電部３０の先端と絶縁板３２の凸部の先端との最短距離、絶縁板３２の凸部の上面の長さおよび絶縁板３２の凸部の先端と他方の導電部３０の先端との最短距離を加算した長さとなる。この場合、図５（ａ）に示した平らな絶縁板３１を用いる場合と比較して導電部３０間の空間距離は長くなる。図５（ｃ）に示すように、凹部が設けられた絶縁板３３を用いる場合は、導電部３０間の空間距離は、２つの導電部３０間の最短距離となる。この場合、図５（ａ）に示した平らな絶縁板３１を用いる場合と導電部３０間の空間距離は同じ長さとなる。したがって、図５（ｂ）に示すように導電部３０間に導電部３０の高さよりも高い凸部が設けられた絶縁板３２を用いる場合は、平らな絶縁板３１を用いる場合と比較して、導電部３０間の空間距離が長くなる。一方、図５（ｃ）に示すように導電部３０間に凹部が設けられた絶縁板３３を用いる場合は、導電部３０間の空間距離は、平らな絶縁板３１を用いる場合と同じ長さになる。 As shown in FIG. 5A, when a flat insulating plate 31 is used, the spatial distance between the conductive parts 30 is the length along the surface of the insulating plate 31. As shown in FIG. 5(b), when using an insulating plate 32 provided with a convex part, the spatial distance between the conductive parts 30 is the same as that between the tip of one conductive part 30 and the tip of the convex part of the insulating plate 32. , the length of the upper surface of the convex portion of the insulating plate 32 , and the shortest distance between the tip of the convex portion of the insulating plate 32 and the tip of the other conductive portion 30 . In this case, the spatial distance between the conductive parts 30 becomes longer than in the case of using the flat insulating plate 31 shown in FIG. 5(a). As shown in FIG. 5C, when an insulating plate 33 provided with a recessed portion is used, the spatial distance between the conductive parts 30 is the shortest distance between two conductive parts 30. In this case, the spatial distance between the conductive parts 30 is the same as in the case of using the flat insulating plate 31 shown in FIG. 5(a). Therefore, as shown in FIG. 5(b), when using an insulating plate 32 in which a convex part higher than the height of the conductive parts 30 is provided between the conductive parts 30, compared to using a flat insulating plate 31, , the spatial distance between the conductive parts 30 becomes longer. On the other hand, when using an insulating plate 33 in which a recess is provided between the conductive parts 30 as shown in FIG. 5(c), the spatial distance between the conductive parts 30 is the same length as when using a flat insulating plate 31. become.

図６は、導電部３０間の沿面距離を説明する図である。図６（ａ）は平らな絶縁板３１を用いる場合、図６（ｂ）は導電部３０間に凸部が設けられた絶縁板３２を用いる場合、図６（ｃ）は導電部３０間に凹部が設けられた絶縁板３３を用いる場合を示す。図６（ａ）～（ｃ）において、破線で示した部分の長さが導電部３０間の沿面距離を示している。 FIG. 6 is a diagram illustrating the creepage distance between the conductive parts 30. 6(a) shows a case where a flat insulating plate 31 is used, FIG. 6(b) shows a case where an insulating plate 32 with a protrusion is provided between the conductive parts 30, and FIG. 6(c) shows a case where a flat insulating plate 31 is used. A case is shown in which an insulating plate 33 provided with a recessed portion is used. In FIGS. 6A to 6C, the length of the portion indicated by the broken line indicates the creepage distance between the conductive parts 30.

図６（ａ）に示すように、平らな絶縁板３１を用いる場合は、導電部３０間の沿面距離は絶縁板３１の表面に沿った長さとなる。図６（ｂ）に示すように、凸部が設けられた絶縁板３２を用いる場合は、導電部３０間の沿面距離は絶縁板３２の凸部を含む表面の外形に沿った距離となる。この場合、図６（ａ）に示した平らな絶縁板３１を用いる場合と比較して導電部３０間の沿面距離は長くなる。図６（ｃ）に示すように、凹部が設けられた絶縁板３３を用いる場合は、導電部３０間の沿面距離は絶縁板３３の凹部を含む表面の外形に沿った長さとなる。この場合、図６（ａ）に示した平らな絶縁板３１を用いる場合と比較して導電部３０間の沿面距離は長くなる。したがって、図６（ｂ）および図６（ｃ）に示すように、導電部３０間に凸部が設けられた絶縁板３２を用いる場合、および、導電部３０間に凹部が設けられた絶縁板３３を用いる場合には、平らな絶縁板３１を用いる場合と比較して、導電部３０間の沿面距離が長くなる。 As shown in FIG. 6A, when a flat insulating plate 31 is used, the creepage distance between the conductive parts 30 is the length along the surface of the insulating plate 31. As shown in FIG. 6B, when an insulating plate 32 provided with a convex portion is used, the creepage distance between the conductive parts 30 is a distance along the outer shape of the surface of the insulating plate 32 including the convex portion. In this case, the creepage distance between the conductive parts 30 becomes longer than in the case of using the flat insulating plate 31 shown in FIG. 6(a). As shown in FIG. 6C, when an insulating plate 33 provided with a recess is used, the creepage distance between the conductive parts 30 is a length along the outer shape of the surface of the insulating plate 33 including the recess. In this case, the creepage distance between the conductive parts 30 becomes longer than in the case of using the flat insulating plate 31 shown in FIG. 6(a). Therefore, as shown in FIG. 6(b) and FIG. 6(c), when using an insulating plate 32 in which a convex part is provided between the conductive parts 30, and in a case where an insulating plate 32 is used in which a concave part is provided between the conductive parts 30, 33, the creepage distance between the conductive parts 30 becomes longer than when using a flat insulating plate 31.

以上のように、平らな絶縁板３１を用いる場合と比較して、導電部３０間に導電部３０の高さよりも高い凸部が設けられた絶縁板３２を用いる場合は、導電部３０間の空間距離と沿面距離が共に長くなり、導電部３０間に凹部が設けられた絶縁板３３を用いる場合は、導電部３０間の沿面距離が長くなるといえる。導電部３０間に凸部または凹部を設けることによって導電部３０間の絶縁距離、すなわち空間距離および／または沿面距離が長くなると、その分だけ導電部３０間の最短距離を短くしても短絡を防ぐことができる。よって、導電部３０間に凸部または凹部を設けることによって絶縁距離を確保しつつ小型化をすることができる。 As described above, compared to the case where a flat insulating plate 31 is used, when the insulating plate 32 in which a convex part higher than the height of the conductive part 30 is provided between the conductive parts 30 is used, the distance between the conductive parts 30 is Both the spatial distance and the creepage distance become long, and when an insulating plate 33 in which a recess is provided between the conductive parts 30 is used, it can be said that the creepage distance between the conductive parts 30 becomes long. If the insulation distance between the conductive parts 30, that is, the spatial distance and/or creepage distance becomes longer by providing a protrusion or a recess between the conductive parts 30, short circuits will not occur even if the shortest distance between the conductive parts 30 is shortened accordingly. It can be prevented. Therefore, by providing a convex portion or a concave portion between the conductive portions 30, it is possible to downsize while ensuring an insulation distance.

したがって、第一の絶縁板４ａの端子用貫通孔５に端子６を挿入した端子台１ａにおいて、第一の絶縁板４ａの回転電機３側の面２１ａにおいて第一の貫通孔１００と第二の貫通孔１０１との間に凹部２３が、第一の絶縁板４ａの外部電源側の面２２において第一の貫通孔１００と第二の貫通孔１０１との間に凹部２４が設けられることで、第一の貫通孔１００に挿入された端子６と第二の貫通孔１０１に挿入された端子６との間の沿面距離を長くすることができる。 Therefore, in the terminal block 1a in which the terminal 6 is inserted into the terminal through-hole 5 of the first insulating plate 4a, the first through-hole 100 and the second through-hole By providing a recess 23 between the through hole 101 and a recess 24 between the first through hole 100 and the second through hole 101 on the external power supply side surface 22 of the first insulating plate 4a, The creepage distance between the terminal 6 inserted into the first through hole 100 and the terminal 6 inserted into the second through hole 101 can be increased.

また、カラー７が導電性材料で形成されている場合、同様に、第一の貫通孔１００に挿入された端子６に装着されたカラー７と第二の貫通孔１０１に挿入された端子６に装着されたカラー７との間の沿面距離も長くすることができる。 In addition, when the collar 7 is formed of a conductive material, similarly, the collar 7 attached to the terminal 6 inserted into the first through hole 100 and the terminal 6 inserted into the second through hole 101 are connected to each other. The creepage distance between the attached collar 7 can also be increased.

また、端子固定用ナット８が導電性材料で形成されている場合、同様に、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６に装着された端子固定用ナット８との間の沿面距離も長くすることができる。 In addition, when the terminal fixing nut 8 is formed of a conductive material, similarly, the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 and the second through hole 101 are connected to each other. The creeping distance between the inserted terminal 6 and the terminal fixing nut 8 attached thereto can also be increased.

凹部２３および凹部２４を設けたことによって端子６間、カラー７間および端子固定用ナット８間の沿面距離が長くなるので、端子６間、カラー７間および端子固定用ナット８間の最短距離を短くしても短絡を防ぐことができる。言い換えると、第一の絶縁板４ａの第一の貫通孔１００と第二の貫通孔１０１との間の距離を短くすることができ、端子台１ａを小型化することができる。 By providing the recesses 23 and 24, the creepage distance between the terminals 6, between the collars 7, and between the terminal fixing nuts 8 becomes longer, so the shortest distance between the terminals 6, between the collars 7, and between the terminal fixing nuts 8 is Short circuits can be prevented even if the length is shortened. In other words, the distance between the first through hole 100 and the second through hole 101 of the first insulating plate 4a can be shortened, and the terminal block 1a can be downsized.

ここで、第一の絶縁板４ａの回転電機３側の面２１ａあるいは第一の絶縁板４ａの外部電源側の面２２において第一の貫通孔１００と第二の貫通孔１０１との間に凸部を設けると、第一の貫通孔１００に挿入された端子６と第二の貫通孔１０１に挿入された端子６との間の沿面距離だけでなく空間距離も長くすることができる。しかし、上述のとおり、空間距離を長くするためには、凸部の高さを導電部すなわち端子６の高さよりも高く設計する必要があり、端子６の長手方向において端子台１ａを小型化することが困難となる。一方、第一の絶縁板４ａに凹部２３および凹部２４を設ける場合は、凹部２３および凹部２４を設けたことに起因して端子６の長手方向における端子台１ａの小型化が妨げられるようなことはない。 Here, a convex portion is formed between the first through hole 100 and the second through hole 101 on the surface 21a of the first insulating plate 4a on the rotating electrical machine 3 side or on the surface 22 of the first insulating plate 4a on the external power source side. By providing a portion, not only the creepage distance but also the spatial distance between the terminal 6 inserted into the first through hole 100 and the terminal 6 inserted into the second through hole 101 can be increased. However, as mentioned above, in order to increase the spatial distance, it is necessary to design the height of the convex part to be higher than the height of the conductive part, that is, the height of the terminal 6, and this reduces the size of the terminal block 1a in the longitudinal direction of the terminal 6. This becomes difficult. On the other hand, when providing the recesses 23 and 24 in the first insulating plate 4a, the provision of the recesses 23 and 24 may impede miniaturization of the terminal block 1a in the longitudinal direction of the terminals 6. There isn't.

以上のように、実施の形態１における端子台１ａは、第一の面である第一の絶縁板４ａの回転電機３側の面２１ａと、回転電機３側の面２１ａと対向する第二の面である外部電源側の面２２と、を有し、回転電機３側の面２１ａから外部電源側の面２２まで貫通する第一の複数の貫通孔である端子用貫通孔５を有し、端子用貫通孔５の各々に端子６を挿入可能である第一の絶縁板４ａを備え、端子用貫通孔５は、第一の貫通孔１００と、第一の貫通孔１００以外の端子用貫通孔５のうち第一の貫通孔１００に最も近い第二の貫通孔１０１と、を含み、第一の絶縁板４ａは、回転電機３側の面２１ａにおいて、第一の貫通孔１００と第二の貫通孔１０１との間に第一の凹部である凹部２３を有し、外部電源側の面２２において、第一の貫通孔１００と第二の貫通孔１０１との間に第二の凹部である凹部２４を有することで、端子６間の絶縁距離を確保しつつ端子台１ａを小型化することができる。 As described above, the terminal block 1a in the first embodiment has a first surface 21a of the first insulating plate 4a on the rotating electrical machine 3 side, and a second surface 21a facing the rotating electrical machine 3 side. a surface 22 on the external power source side which is a surface, and terminal through holes 5 which are first plurality of through holes penetrating from the surface 21a on the rotating electric machine 3 side to the surface 22 on the external power source side; Each of the terminal through-holes 5 includes a first insulating plate 4a into which a terminal 6 can be inserted, and the terminal through-holes 5 include a first through-hole 100 and terminal through-holes other than the first through-hole 100. The first insulating plate 4a includes a second through hole 101 that is closest to the first through hole 100 among the holes 5, and the first insulating plate 4a has a first through hole 100 and a second through hole 101 on the surface 21a on the rotating electric machine 3 side. A recess 23, which is a first recess, is provided between the first through hole 101 and the second through hole 101, and a second recess is provided between the first through hole 100 and the second through hole 101 on the external power supply side surface 22. By having a certain recess 24, it is possible to downsize the terminal block 1a while ensuring the insulation distance between the terminals 6.

また、回転電機３と、回転電機３と電気的に接続された端子台１ａを備えることで、端子６間の絶縁距離を確保しつつ端子台１ａを小型化したエレベータ装置を得ることができる。 Moreover, by providing the rotating electrical machine 3 and the terminal block 1a electrically connected to the rotating electrical machine 3, it is possible to obtain an elevator apparatus in which the terminal block 1a is miniaturized while ensuring the insulation distance between the terminals 6.

なお、実施の形態１では、第一の絶縁板４ａの回転電機３側の面２１ａに凹部２３を設け、外部電源側の面２２に凹部２４を設けたが、第一の絶縁板４ａの回転電機３側の面２１ａだけに凹部２３を設け、外部電源側の面２２には凹部２４を設けないようにしてもよいし、逆に、第一の絶縁板４ａの回転電機３側の面２１ａには凹部２３を設けずに、外部電源側の面２２だけに凹部２４を設けてもよい。これらの場合においても、端子６間の絶縁距離を確保しつつ端子台１ａを小型化することができる。 In the first embodiment, the recess 23 is provided in the surface 21a of the first insulating plate 4a facing the rotating electrical machine 3, and the recess 24 is provided in the surface 22 facing the external power source. The recess 23 may be provided only on the surface 21a on the electric machine 3 side and the recess 24 may not be provided on the surface 22 on the external power supply side, or conversely, the recess 23 may be provided on the surface 21a on the rotating electric machine 3 side of the first insulating plate 4a. Instead of providing the recess 23, the recess 24 may be provided only on the surface 22 facing the external power source. Even in these cases, the terminal block 1a can be downsized while ensuring the insulation distance between the terminals 6.

なお、実施の形態１では、凹部２３および凹部２４は、第一の絶縁板４ａの第一の貫通孔１００と第二の貫通孔１０１との間に線状の溝を作るように形成されているが、凹部２３および凹部２４の形状は線状の溝には限定されない。例えば、回転電機３側あるいは外部電源側から見た平面視において丸い形状や多角形の形状の凹部２３および凹部２４を形成してもよい。 In the first embodiment, the recesses 23 and 24 are formed to form a linear groove between the first through hole 100 and the second through hole 101 of the first insulating plate 4a. However, the shapes of the recesses 23 and 24 are not limited to linear grooves. For example, the recesses 23 and 24 may have a round shape or a polygonal shape when viewed from above from the rotating electric machine 3 side or from the external power source side.

さらに、実施の形態１では、第一の絶縁板４ａの回転電機３側の面２１ａの第一の貫通孔１００と第二の貫通孔１０１との間に１つの凹部２３を、外部電源側の面２２の第一の貫通孔１００と第二の貫通孔１０１との間に１つの凹部２４を設けたが、第一の絶縁板４ａの回転電機３側の面２１ａの第一の貫通孔１００と第二の貫通孔１０１との間に２つ以上の凹部２３を設けてもよいし、外部電源側の面２２の第一の貫通孔１００と第二の貫通孔１０１との間に２つ以上の凹部２４を設けてもよい。 Furthermore, in the first embodiment, one recess 23 is provided between the first through hole 100 and the second through hole 101 on the surface 21a of the first insulating plate 4a on the side of the rotating electric machine 3, and the one recess 23 is provided on the side of the external power source. Although one recess 24 was provided between the first through hole 100 and the second through hole 101 on the surface 22, the first through hole 100 on the surface 21a on the rotating electric machine 3 side of the first insulating plate 4a Two or more recesses 23 may be provided between the first through hole 100 and the second through hole 101 on the surface 22 on the external power supply side. The above recess 24 may be provided.

なお、実施の形態１では、端子台１ａがエレベータの回転電機３に電力供給を行うために使用される例について説明したが、エレベータの回転電機３に限らず、その他の電気機器に使用される回転電機に電力供給を行うために端子台１ａを使用してもよい。また、端子台１ａは、電力供給以外の目的で機器間を電気的に接続するためにも使用可能である。例えば、端子台１ａは、電気機器の制御盤内部の電磁リレーやＰＬＣ、インバータ等を電気的に接続するための中継器として使用されてもよいし、電気機器の制御盤外部に設けられた中継箱内の中継器として使用されてもよい。 In addition, in Embodiment 1, an example was explained in which the terminal block 1a is used to supply power to the rotating electric machine 3 of an elevator, but the terminal block 1a is used not only for the rotating electric machine 3 of the elevator but also for other electrical equipment. The terminal block 1a may be used to supply power to the rotating electric machine. Furthermore, the terminal block 1a can also be used to electrically connect devices for purposes other than power supply. For example, the terminal block 1a may be used as a relay for electrically connecting an electromagnetic relay, PLC, inverter, etc. inside a control panel of an electrical device, or as a relay provided outside a control panel of an electrical device. May be used as a repeater inside the box.

実施の形態２．
実施の形態２における端子台１ｂの構成を説明する。図７は実施の形態２における第一の絶縁板４ｂを示す図である。図７（ａ）は回転電機３側から見た図であり、図７（ｂ）は外部電源側から見た図である。実施の形態２における第一の絶縁板４ｂは、第一の面である回転電機３側の面２１ｂに固定部材用凹部である切り欠き４０を有する点が実施の形態１の第一の絶縁板４ａと相違する。なお、実施の形態１と同一の構成には同一符号を付してその説明を省略する。なお、実施の形態２では端子固定用ナット８は導電性材料で形成されているものとする。 Embodiment 2.
The configuration of the terminal block 1b in the second embodiment will be explained. FIG. 7 is a diagram showing the first insulating plate 4b in the second embodiment. FIG. 7(a) is a diagram seen from the rotating electric machine 3 side, and FIG. 7(b) is a diagram seen from the external power supply side. The first insulating plate 4b in the second embodiment is different from the first insulating plate in the first embodiment in that the first insulating plate 4b has a notch 40, which is a recess for a fixing member, on the first surface 21b on the rotating electric machine 3 side. Different from 4a. Note that the same components as those in Embodiment 1 are given the same reference numerals, and their descriptions will be omitted. In the second embodiment, it is assumed that the terminal fixing nut 8 is made of a conductive material.

図７（ａ）に示すように、切り欠き４０は、第一の絶縁板４ｂの回転電機３側の面２１ｂに、回転電機３側の面２１ｂを平面視で見たときに端子用貫通孔５をそれぞれ含むように設けられている。以下では、複数の切り欠き４０のうち、回転電機３側の面２１ｂを平面視で見たときに第一の貫通孔１００を内部に含む切り欠き４０に注目して説明する。そのため、以下では、特段の説明無しに単に「切り欠き４０」と記載すれば、回転電機３側の面２１ｂを平面視で見たときに第一の貫通孔１００を内部に含む切り欠き４０を指すものとする。 As shown in FIG. 7(a), the notch 40 is a through-hole for a terminal in the surface 21b of the first insulating plate 4b on the rotating electrical machine 3 side, when the surface 21b on the rotating electrical machine 3 side is viewed from above. 5, respectively. In the following description, among the plurality of notches 40, the notch 40 that includes the first through hole 100 therein when the surface 21b on the rotating electric machine 3 side is viewed in plan will be described. Therefore, in the following, simply writing "notch 40" without special explanation will mean the notch 40 that includes the first through hole 100 inside when the surface 21b on the rotating electrical machine 3 side is viewed from above. It shall point to

切り欠き４０は、回転電機３側の面２１ｂに平行な断面において、第二の貫通孔１０１に最も近い側壁部に、第一の貫通孔１００の中心と第二の貫通孔１０１の中心とを結ぶ直線と垂直な第一の直線部４１を有する。また、第二の貫通孔１０１に最も近い側壁部と対向する側壁部に、第一の直線部４１に平行な第二の直線部４２を有する。なお、図７（ａ）では、第二の貫通孔１０１は２つ図示されているが、第一の貫通孔１００と第一の貫通孔１００の上側に位置する第二の貫通孔１０１との位置関係に注目して、第一の直線部４１および第二の直線部４２を図示している。第一の貫通孔１００と第一の貫通孔１００の下側に位置する第二の貫通孔１０１との間の位置関係に注目する場合は、切り欠き４０の側壁部のうち図７（ａ）における下側の側壁部に第一の直線部４１が、図７における上側の側壁部に第二の直線部４２が設けられる。なお、ここで、「垂直」や「平行」とは、厳密な意味での垂直や平行だけでなく、多少のずれがあっても実質的に垂直や平行と言えるものも含むものとする。 The notch 40 is formed in the side wall portion closest to the second through hole 101 in a cross section parallel to the surface 21b on the side of the rotating electric machine 3, so that the center of the first through hole 100 and the center of the second through hole 101 are connected to each other. It has a first straight portion 41 perpendicular to the connecting straight line. Further, a second straight portion 42 parallel to the first straight portion 41 is provided on a side wall portion opposite to the side wall portion closest to the second through hole 101 . Although two second through holes 101 are shown in FIG. 7(a), the first through hole 100 and the second through hole 101 located above the first through hole 100 The first straight section 41 and the second straight section 42 are illustrated with attention to their positional relationship. When focusing on the positional relationship between the first through hole 100 and the second through hole 101 located below the first through hole 100, the side wall of the notch 40 shown in FIG. A first straight portion 41 is provided on the lower side wall in FIG. 7, and a second straight portion 42 is provided on the upper side wall in FIG. Note that "perpendicular" and "parallel" herein include not only perpendicular and parallel in the strict sense, but also those that can be said to be substantially perpendicular or parallel even if there is some deviation.

FIG. 9 is a diagram showing the positional relationship between the notch 40 of the first insulating plate 4b and the terminal fixing nut 8 in the second embodiment. 9(a) shows a case where the outer shape of the terminal fixing nut 8 is a regular hexagon, FIG. 9(b) shows a case where the outer shape of the terminal fixing nut 8 is a hexagon, and FIG. 9(c) shows a case where the terminal fixing nut 8 has a hexagonal outer shape. FIG. 8 is a diagram showing a case where the outer shape of 8 is a pentagon.

実施の形態２において用いられる端子固定用ナット８は、第一の絶縁板４ｂの回転電機３側の面２１ｂと平行な断面における外形の一部に直線部４３を有する。例えば、図９（ａ）～（ｃ）に示すように、端子固定用ナット８の外形が多角形である場合、この多角形の一辺が直線部４３である。また、端子固定用ナット８は、貫通孔１０２を有し、この貫通孔１０２に端子６を挿入して端子固定用ナット８を締めることで端子６と第一の絶縁板４ｂとを固定することができる。なお、端子固定用ナット８としては、図９（ａ）に示すような外形が正六角形である六角ナットを用いることがより好ましい。ここで、「多角形」や「正六角形」とは、厳密な意味での多角形や正六角形だけでなく、例えば頂点部分が面取り加工されていたり多少の歪みがあったりしても実質的に多角形や正六角形と言えるものも含むものとする。 The terminal fixing nut 8 used in the second embodiment has a straight portion 43 in a part of its outer shape in a cross section parallel to the rotating electric machine 3 side surface 21b of the first insulating plate 4b. For example, as shown in FIGS. 9(a) to 9(c), when the outer shape of the terminal fixing nut 8 is a polygon, one side of this polygon is the straight portion 43. Further, the terminal fixing nut 8 has a through hole 102, and by inserting the terminal 6 into the through hole 102 and tightening the terminal fixing nut 8, the terminal 6 and the first insulating plate 4b can be fixed. I can do it. As the terminal fixing nut 8, it is more preferable to use a hexagonal nut having a regular hexagonal outer shape as shown in FIG. 9(a). Here, "polygon" and "regular hexagon" do not only mean polygons or regular hexagons in the strict sense, but also, for example, even if the apex part is chamfered or slightly distorted, It also includes polygons and regular hexagons.

第一の貫通孔１００に挿入された端子６と第一の絶縁板４ｂとを端子固定用ナット８によって固定するとき、端子固定用ナット８は、端子固定用ナット８の直線部４３が切り欠き４０の第一の直線部４１と接触するように切り欠き４０内に配置される。端子固定用ナット８の直線部４３と切り欠き４０の第一の直線部４１とが互いに接触するように切り欠き４０内に端子固定用ナット８を配置することによって、端子固定用ナット８が切り欠き４０内で回転することを防ぐことができる。例えば、図９（ａ）～（ｃ）に示すように、端子固定用ナット８の外形が多角形である場合について説明すると、端子固定用ナット８が制限なく回転可能な場合、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８の外形の頂点部分が第二の貫通孔１０１に挿入された端子６側を向いてしまうことがある。そうすると、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８の直線部４３が第二の貫通孔１０１に挿入された端子６側を向く場合と比較して、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６との最短距離、あるいは、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６に装着された端子固定用ナット８との最短距離が短くなり、絶縁距離の確保が難しくなる。したがって、端子固定用ナット８の直線部４３と切り欠き４０の第一の直線部４１とが互いに接触するように切り欠き４０内に端子固定用ナット８を配置して端子固定用ナット８が切り欠き４０内で回転することを防ぐことによって、絶縁距離を確保することができる。なお、必ずしも端子固定用ナット８の直線部４３の全面が切り欠き４０の第一の直線部４１に接触している必要はなく、端子固定用ナット８の直線部４３の少なくとも一部が切り欠き４０の第一の直線部４１に接触していればよい。 When fixing the terminal 6 inserted into the first through hole 100 and the first insulating plate 4b with the terminal fixing nut 8, the straight part 43 of the terminal fixing nut 8 is notched. It is arranged in the notch 40 so as to be in contact with the first straight portion 41 of the cutout 40 . By arranging the terminal fixing nut 8 in the notch 40 so that the straight part 43 of the terminal fixing nut 8 and the first straight part 41 of the notch 40 are in contact with each other, the terminal fixing nut 8 is cut. Rotation within the notch 40 can be prevented. For example, as shown in FIGS. 9(a) to 9(c), when the outer shape of the terminal fixing nut 8 is polygonal, if the terminal fixing nut 8 is rotatable without restriction, the first through-hole The apex portion of the outer shape of the terminal fixing nut 8 attached to the terminal 6 inserted into the hole 100 may face toward the terminal 6 inserted into the second through hole 101. In this case, compared to the case where the straight portion 43 of the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 faces the terminal 6 inserted into the second through hole 101, The shortest distance between the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 and the terminal 6 inserted into the second through hole 101, or the shortest distance between the terminal 6 inserted into the first through hole 100 The shortest distance between the terminal fixing nut 8 attached to the terminal 6 and the terminal fixing nut 8 attached to the terminal 6 inserted into the second through hole 101 becomes short, making it difficult to secure an insulation distance. Therefore, the terminal fixing nut 8 is arranged in the notch 40 so that the straight part 43 of the terminal fixing nut 8 and the first straight part 41 of the notch 40 are in contact with each other, and the terminal fixing nut 8 is notched. By preventing rotation within the notch 40, an insulation distance can be ensured. Note that the entire surface of the straight portion 43 of the terminal fixing nut 8 does not necessarily have to be in contact with the first straight portion 41 of the notch 40, and at least a portion of the straight portion 43 of the terminal fixing nut 8 is notched. It is sufficient if the first straight portion 41 of 40 is contacted.

次に、切り欠き４０の第一の直線部４１と第二の直線部４２との間の距離について説明する。第一の直線部４１と第二の直線部４２との間の距離は、第一の貫通孔１００に端子６が挿入され、端子固定用ナット８が端子６に装着された状態において、端子固定用ナット８が切り欠き４０内で回転することを防ぐように設計される。 Next, the distance between the first straight part 41 and the second straight part 42 of the notch 40 will be explained. The distance between the first straight part 41 and the second straight part 42 is determined when the terminal 6 is inserted into the first through hole 100 and the terminal fixing nut 8 is attached to the terminal 6. The nut 8 is designed to prevent rotation within the notch 40.

より具体的には、図９（ａ）～（ｃ）に示すように、第一の絶縁板４ｂの回転電機３側の面２１ｂに平行な断面において、端子固定用ナット８の貫通孔１０２の中心が第一の直線部４１と第二の直線部４２との間の中間に位置する場合を想定して説明する。図９（ａ）～（ｃ）において、端子固定用ナット８の貫通孔１０２の中心と端子固定用ナット８の外周上の点を結ぶ線分のうち最も長い線分の２倍の長さを持つ線分を線分Ａ、端子固定用ナット８の直線部４３と垂直な直線が交わる端子固定用ナット８の外周上の２点を結ぶ線分のうち最も長い線分を線分Ｂとする。 More specifically, as shown in FIGS. 9(a) to 9(c), in a cross section parallel to the surface 21b of the first insulating plate 4b on the rotating electric machine 3 side, the through hole 102 of the terminal fixing nut 8 is The following description assumes that the center is located midway between the first straight section 41 and the second straight section 42. In FIGS. 9(a) to 9(c), the length of the longest line connecting the center of the through hole 102 of the terminal fixing nut 8 and a point on the outer periphery of the terminal fixing nut 8 is twice the length of the longest line segment. The line segment having the terminal fixing nut 8 is defined as a line segment A, and the longest line segment connecting two points on the outer periphery of the terminal fixing nut 8 where a straight line perpendicular to the straight line part 43 of the terminal fixing nut 8 intersects is defined as a line segment B. .

第一の直線部４１と第二の直線部４２との間の距離が、線分Ａの長さ以上である場合、端子固定用ナット８が第一の直線部４１および第二の直線部４２と接触しないので、端子固定用ナット８が制限なく回転してしまう可能性がある。一方で、第一の直線部４１と第二の直線部４２との間の距離が、線分Ｂの長さより小さい場合、端子固定用ナット８の直線部４３が切り欠き４０の第一の直線部４１に接触した状態で切り欠き４０内に端子固定用ナット８を配置することができない。よって、第一の直線部４１と第二の直線部４２との間の距離は、線分Ａの長さよりも小さく、すなわち、端子固定用ナット８の貫通孔１０２の中心と端子固定用ナット８の外周上の点を結ぶ線分のうち最も長い線分の長さの２倍よりも小さくなるように設計される。これにより、端子固定用ナット８が切り欠き４０内で第一の直線部４１または第二の直線部４２と干渉するので、切り欠き４０内で端子固定用ナット８が回転することを防ぐことができる。さらに、第一の直線部４１と第二の直線部４２との間の距離は、線分Ｂの長さ以上に、すなわち、端子固定用ナット８の直線部４３と垂直な直線が交わる端子固定用ナット８の外周上の２点を結ぶ線分のうち最も長い線分の長さ以上になるように設計される。これにより、端子固定用ナット８の直線部４３が切り欠き４０の第一の直線部４１に接触した状態で切り欠き４０内に端子固定用ナット８を配置することができる。 When the distance between the first straight part 41 and the second straight part 42 is longer than the length of the line segment A, the terminal fixing nut 8 is attached to the first straight part 41 and the second straight part 42. Since the terminal fixing nut 8 does not come into contact with the terminal fixing nut 8, there is a possibility that the terminal fixing nut 8 may rotate without restriction. On the other hand, if the distance between the first straight part 41 and the second straight part 42 is smaller than the length of the line segment B, the straight part 43 of the terminal fixing nut 8 is aligned with the first straight line of the notch 40. The terminal fixing nut 8 cannot be placed inside the notch 40 while being in contact with the portion 41 . Therefore, the distance between the first straight part 41 and the second straight part 42 is smaller than the length of the line segment A, that is, the distance between the center of the through hole 102 of the terminal fixing nut 8 and the terminal fixing nut 8 is smaller than the length of the line segment A. The length of the line segment is designed to be less than twice the length of the longest line segment connecting points on the outer periphery of the line segment. As a result, the terminal fixing nut 8 interferes with the first linear portion 41 or the second linear portion 42 within the notch 40, so that it is possible to prevent the terminal fixing nut 8 from rotating within the notch 40. can. Further, the distance between the first straight part 41 and the second straight part 42 is longer than the length of the line segment B, that is, the distance between the first straight part 41 and the second straight part 42 is longer than the length of the line segment B, that is, the distance between the first straight part 41 and the second straight part 42 is longer than the length of the straight part 43 of the terminal fixing nut 8. The length is designed to be longer than the longest line segment connecting two points on the outer circumference of the nut 8. Thereby, the terminal fixing nut 8 can be placed in the notch 40 with the straight part 43 of the terminal fixing nut 8 in contact with the first straight part 41 of the notch 40.

以上のように、第一の絶縁板４ｂは、第一の面である回転電機３側の面２１ｂを平面視で見たときに第一の貫通孔１００を内部に含む固定部材用凹部である切り欠き４０を有し、切り欠き４０は、第一の絶縁板４ｂの回転電機３側の面２１ｂに平行な断面において、第二の貫通孔１０１に最も近い側壁部に、第一の貫通孔１００の中心と第二の貫通孔１０１の中心とを結ぶ直線と垂直な第一の直線部４１を有し、導電性材料で形成され、第一の絶縁板４ｂの回転電機３側の面２１ｂと平行な断面における外形の一部に直線部４３を有し、第一の貫通孔１００に挿入された端子６と第一の絶縁板４ｂとを固定する固定部材である端子固定用ナット８を、切り欠き４０の第一の直線部４１と端子固定用ナット８の直線部４３が接触するように切り欠き４０内に配置可能とすることで、端子固定用ナット８が切り欠き４０内で回転することを防ぐことができる。これにより、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６との間の絶縁距離、あるいは、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６に装着された端子固定用ナット８との間の絶縁距離を確保することができ、端子台１ｂを小型化することができる。 As described above, the first insulating plate 4b is a fixing member recess that includes the first through hole 100 therein when the first surface 21b on the side of the rotating electric machine 3 is viewed from above. The notch 40 has a first through hole in the side wall portion closest to the second through hole 101 in a cross section parallel to the surface 21b of the first insulating plate 4b on the rotating electric machine 3 side. 100 and the center of the second through hole 101, is formed of a conductive material, and has a surface 21b on the rotating electric machine 3 side of the first insulating plate 4b. A terminal fixing nut 8, which is a fixing member that has a linear portion 43 in a part of its outer shape in a cross section parallel to the above, and fixes the terminal 6 inserted into the first through hole 100 and the first insulating plate 4b. By making it possible to arrange the terminal fixing nut 8 in the notch 40 so that the first straight part 41 of the notch 40 and the straight part 43 of the terminal fixing nut 8 are in contact with each other, the terminal fixing nut 8 rotates within the notch 40. can be prevented from happening. Thereby, the insulation distance between the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 and the terminal 6 inserted into the second through hole 101, or the It is possible to ensure an insulation distance between the terminal fixing nut 8 attached to the terminal 6 inserted into the hole 100 and the terminal fixing nut 8 attached to the terminal 6 inserted into the second through hole 101. Therefore, the terminal block 1b can be downsized.

また、切り欠き４０は、第一の絶縁板４ｂの回転電機３側の面２１ｂに平行な断面において、第二の貫通孔１０１に最も近い側壁部と対向する側壁部に、第一の直線部４１に平行な第二の直線部４２を有し、端子固定用ナット８は、端子６を挿入可能な貫通孔１０２を有し、第一の直線部４１と第二の直線部４２との間の距離は、第一の絶縁板４ｂの回転電機３側の面２１ｂと平行な断面において、端子固定用ナット８の貫通孔１０２の中心と端子固定用ナット８の外周上の点を結ぶ線分のうち最も長い線分の長さの２倍よりも小さく、端子固定用ナット８の直線部４３と垂直な直線が交わる端子固定用ナット８の外周上の２点を結ぶ線分のうち最も長い線分の長さ以上であることで、端子固定用ナット８が切り欠き４０内で回転することを防ぐことができる。これにより、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６との間の絶縁距離、あるいは、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６に装着された端子固定用ナット８との間の絶縁距離を確保することができ、端子台１ｂを小型化することができる。 In addition, the notch 40 has a first linear portion in a side wall portion opposite to the side wall portion closest to the second through hole 101 in a cross section parallel to the surface 21b of the first insulating plate 4b on the rotating electric machine 3 side. 41, the terminal fixing nut 8 has a through hole 102 into which the terminal 6 can be inserted, and the terminal fixing nut 8 has a through hole 102 in which the terminal 6 can be inserted. The distance is a line segment connecting the center of the through hole 102 of the terminal fixing nut 8 and a point on the outer periphery of the terminal fixing nut 8 in a cross section parallel to the surface 21b of the first insulating plate 4b on the rotating electrical machine 3 side. The length of the longest line segment is smaller than twice the length of the longest line segment, and the longest line segment connects two points on the outer periphery of the terminal fixing nut 8 where the straight line perpendicular to the straight line part 43 of the terminal fixing nut 8 intersects. By being longer than the length of the line segment, it is possible to prevent the terminal fixing nut 8 from rotating within the notch 40. Thereby, the insulation distance between the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 and the terminal 6 inserted into the second through hole 101, or the It is possible to ensure an insulation distance between the terminal fixing nut 8 attached to the terminal 6 inserted into the hole 100 and the terminal fixing nut 8 attached to the terminal 6 inserted into the second through hole 101. Therefore, the terminal block 1b can be downsized.

なお、実施の形態２では、切り欠き４０の第一の直線部４１が、回転電機３側の面２１ｂに平行な断面において、第一の貫通孔１００の中心と第二の貫通孔１０１の中心とを結ぶ直線と垂直になるように設けられているが、第一の直線部４１は、第一の貫通孔１００の中心と第二の貫通孔１０１の中心とを結ぶ直線と垂直でなくてもよい。例えば、端子固定用ナット８として外形が正六角形である六角ナットを用いる場合、切り欠き４０の第一の直線部４１を、第一の貫通孔１００の中心と第二の貫通孔１０１の中心とを結ぶ直線とのなす角が６０度より大きく９０度以下になるように設けることができる。これにより、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８の外形の頂点部分が第二の貫通孔１０１に挿入された端子６側を向く場合と比較して、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６との間の絶縁距離、あるいは、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６に装着された端子固定用ナット８との間の絶縁距離を確保することができ、端子台１ｂを小型化することができる。なお、ここで、「なす角」とは、２つの直線によって形成される角のうち角度が小さい方を指すものとする。 Note that in the second embodiment, the first linear portion 41 of the notch 40 is located between the center of the first through hole 100 and the center of the second through hole 101 in a cross section parallel to the surface 21b on the rotating electrical machine 3 side. However, the first straight portion 41 is not perpendicular to the straight line connecting the center of the first through hole 100 and the center of the second through hole 101. Good too. For example, when using a hexagonal nut with a regular hexagonal outer shape as the terminal fixing nut 8, the first straight portion 41 of the notch 40 is aligned with the center of the first through hole 100 and the center of the second through hole 101. It can be provided so that the angle formed with a straight line connecting the two is greater than 60 degrees and less than 90 degrees. As a result, compared to the case where the apex part of the outer shape of the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 faces the side of the terminal 6 inserted into the second through hole 101, , the insulation distance between the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 and the terminal 6 inserted into the second through hole 101, or the first through hole 100 An insulation distance can be secured between the terminal fixing nut 8 attached to the terminal 6 inserted into the second through hole 101 and the terminal fixing nut 8 attached to the terminal 6 inserted into the second through hole 101. The terminal block 1b can be downsized. Note that the term "angle formed" herein refers to the smaller angle of the angles formed by two straight lines.

なお、実施の形態２では、図７（ａ）、図８（ａ）および図９に示すように、切り欠き４０として、第一の絶縁板４ｂの回転電機３側の面２１ｂに平行な断面において、第一の直線部４１、第二の直線部４２および第一の直線部４１と第二の直線部４２とを接続する曲線部を有する形状の溝を設けたが、切り欠き４０の形状はこれに限定されない。例えば、第一の直線部４１と第二の直線部４２とを接続する曲線部の代わりに直線部を設けてもよい。また、第二の直線部４２の代わりに曲線部を設けてもよい。また、実施の形態２では、図９における右側部分には側壁を有さない形状の切り欠き４０を設けたが、図９における右側部分にも側壁を有する形状の切り欠き４０を設けてもよい。この場合の右側部分の側壁の形状は、直線状であっても、曲線状であってもよい。 In the second embodiment, as shown in FIGS. 7(a), 8(a), and 9, the cutout 40 is a cross section parallel to the surface 21b of the first insulating plate 4b on the rotating electrical machine 3 side. In , a groove having a shape having a first straight part 41 , a second straight part 42 , and a curved part connecting the first straight part 41 and the second straight part 42 was provided, but the shape of the notch 40 is not limited to this. For example, a straight part may be provided instead of the curved part connecting the first straight part 41 and the second straight part 42. Further, a curved portion may be provided instead of the second straight portion 42. Further, in the second embodiment, the cutout 40 having a shape without a side wall is provided in the right side portion in FIG. 9, but the cutout 40 in a shape having a side wall may also be provided in the right side portion in FIG. . In this case, the shape of the side wall of the right side portion may be linear or curved.

Note that the same components as those in the second embodiment are given the same reference numerals, and their explanations will be omitted. In the third embodiment, it is assumed that the terminal fixing nut 8 is made of a conductive material.

図１０において、第二の絶縁板５０は、第一の絶縁板４ｂの回転電機３側の面２１ｂと接触し、凸部５３が第一の絶縁板４ｂの凹部２３と嵌合するように配置される。また、各端子６は、第一の絶縁板４ｂの端子用貫通孔５および第二の絶縁板５０の端子用貫通孔５４に挿入されている。また、各スタッドボルト１０は、第一の絶縁板４ｂのスタッドボルト用貫通孔９および第二の絶縁板５０のスタッドボルト用貫通孔５５に挿入されている。第一の絶縁板４ｂおよび第二の絶縁板５０を挟んで各スタッドボルト１０の回転電機３側と外部電源側にそれぞれスタッドボルト固定用ナット１１を装着することで、スタッドボルト１０、第一の絶縁板４ｂおよび第二の絶縁板５０が固定されている。 In FIG. 10, the second insulating plate 50 is arranged so that it contacts the surface 21b of the first insulating plate 4b on the rotating electric machine 3 side, and the convex part 53 fits into the concave part 23 of the first insulating plate 4b. be done. Moreover, each terminal 6 is inserted into the terminal through-hole 5 of the first insulating plate 4b and the terminal through-hole 54 of the second insulating plate 50. Further, each stud bolt 10 is inserted into a stud bolt through hole 9 of the first insulating plate 4b and a stud bolt through hole 55 of the second insulating plate 50. By attaching the stud bolt fixing nuts 11 to the rotating electric machine 3 side and the external power supply side of each stud bolt 10 with the first insulating plate 4b and the second insulating plate 50 in between, the stud bolts 10 and the first Insulating plate 4b and second insulating plate 50 are fixed.

図１１において、第二の絶縁板５０は、第一の絶縁板４ｂの回転電機３側の面２１ｂと接触する接触面である外部電源側の面５１と、外部電源側の面５１と対向する対向面である回転電機３側の面５２と、を有し、外部電源側の面５１から回転電機３側の面５２まで貫通する第二の複数の貫通孔である複数の端子用貫通孔５４および複数のスタッドボルト用貫通孔５５を有する。さらに、第二の絶縁板５０は、外部電源側の面５１に凸部５３を有する。第二の絶縁板５０は絶縁体で形成される。 In FIG. 11, the second insulating plate 50 faces an external power source side surface 51, which is a contact surface that contacts the rotating electric machine 3 side surface 21b of the first insulating plate 4b, and an external power source side surface 51. A plurality of terminal through-holes 54 are second plurality of through-holes that penetrate from the surface 51 on the external power supply side to the surface 52 on the rotary electric machine 3 side, and have a surface 52 on the rotating electrical machine 3 side that is an opposing surface. and a plurality of through holes 55 for stud bolts. Further, the second insulating plate 50 has a convex portion 53 on the surface 51 facing the external power source. The second insulating plate 50 is made of an insulator.

各端子用貫通孔５４には端子６をそれぞれ挿入可能であり、各スタッドボルト用貫通孔５５にはスタッドボルト１０をそれぞれ挿入可能である。また、複数の端子用貫通孔５４は、第一の絶縁板４ｂの第一の貫通孔１００に対応する位置に設けられた第三の貫通孔１０３と、第一の絶縁板４ｂの第二の貫通孔１０１に対応する位置に設けられた第四の貫通孔１０４と、を含む。言い換えると、第三の貫通孔１０３以外の端子用貫通孔５４のうち第三の貫通孔１０３に最も近い端子用貫通孔５４が第四の貫通孔１０４である。また、外部電源側の面５１に平行な断面における端子用貫通孔５４の各々の形状は、端子固定用ナット８によって端子６と第一の絶縁板４ｂが固定され、端子６が端子用貫通孔５４に挿入された状態において、端子固定用ナット８と端子用貫通孔５４の各々の側壁との間に空間を有するように形成されている。言い換えると、端子用貫通孔５４は、端子固定用ナット８と端子用貫通孔５４の側壁とが互いに接触しないような形状および大きさを有する。 A terminal 6 can be inserted into each terminal through hole 54, and a stud bolt 10 can be inserted into each stud bolt through hole 55. Further, the plurality of terminal through holes 54 include a third through hole 103 provided at a position corresponding to the first through hole 100 of the first insulating plate 4b, and a second through hole 103 of the first insulating plate 4b. A fourth through hole 104 provided at a position corresponding to the through hole 101 is included. In other words, among the terminal through holes 54 other than the third through hole 103 , the terminal through hole 54 closest to the third through hole 103 is the fourth through hole 104 . Further, the shape of each terminal through hole 54 in a cross section parallel to the surface 51 on the external power supply side is such that the terminal 6 and the first insulating plate 4b are fixed by the terminal fixing nut 8, and the terminal 6 is fixed to the terminal through hole 54. 54, a space is formed between the terminal fixing nut 8 and each side wall of the terminal through hole 54. In other words, the terminal through hole 54 has a shape and size such that the terminal fixing nut 8 and the side wall of the terminal through hole 54 do not come into contact with each other.

凸部５３は、第二の絶縁板５０の外部電源側の面５１において、第三の貫通孔１０３と第四の貫通孔１０４との間に形成されている。凸部５３は、例えば、図１１（ｂ）に示すように、第三の貫通孔１０３と第四の貫通孔１０４との間に線状の突起を作るように形成されている。また、凸部５３は第一の絶縁板４ｂの回転電機３側の面２１ｂの凹部２３と篏合できるように形成されている。 The convex portion 53 is formed between the third through hole 103 and the fourth through hole 104 on the external power supply side surface 51 of the second insulating plate 50 . The convex portion 53 is formed to form a linear protrusion between the third through hole 103 and the fourth through hole 104, for example, as shown in FIG. 11(b). Further, the convex portion 53 is formed so as to be able to fit into the concave portion 23 on the surface 21b of the first insulating plate 4b on the rotating electric machine 3 side.

次に、実施の形態３における端子固定用ナット８間の空間距離について説明する。図１２は、実施の形態３における端子固定用ナット８間の空間距離を説明する図である。図１２（ａ）は比較例として実施の形態２における端子固定用ナット８間の空間距離を示し、図１２（ｂ）は実施の形態３における端子固定用ナット８間の空間距離を示す。なお、図１２において破線で示した部分の長さが端子固定用ナット８間の空間距離を示している。 Next, the spatial distance between the terminal fixing nuts 8 in Embodiment 3 will be explained. FIG. 12 is a diagram illustrating the spatial distance between the terminal fixing nuts 8 in the third embodiment. FIG. 12(a) shows the spatial distance between the terminal fixing nuts 8 in the second embodiment as a comparative example, and FIG. 12(b) shows the spatial distance between the terminal fixing nuts 8 in the third embodiment. In addition, the length of the part shown by the broken line in FIG. 12 shows the spatial distance between the terminal fixing nuts 8.

図１２（ａ）に示すように、実施の形態２では、第二の絶縁板５０を用いずに第一の絶縁板４ｂのみを用いており、端子固定用ナット８は、第一の絶縁板４ｂの切り欠き４０から、回転電機３側に一部が露出している。よって、端子固定用ナット８間の空間距離は、一方の端子固定用ナット８と他方の端子固定用ナット８との最短距離となる。 As shown in FIG. 12(a), in the second embodiment, only the first insulating plate 4b is used without using the second insulating plate 50, and the terminal fixing nut 8 is attached to the first insulating plate 4b. A portion is exposed to the rotating electric machine 3 side from the notch 40 of 4b. Therefore, the spatial distance between the terminal fixing nuts 8 is the shortest distance between one terminal fixing nut 8 and the other terminal fixing nut 8.

一方で、図１２（ｂ）に示すように、実施の形態３では、第一の絶縁板４ｂおよび第二の絶縁板５０を用いている。端子固定用ナット８は、第一の絶縁板４ｂの切り欠き４０から、回転電機３側に一部が露出しているが、切り欠き４０から露出している部分は第二の絶縁板５０の端子用貫通孔５４内に位置し、端子用貫通孔５４の側壁によって周囲を囲われている。よって、端子固定用ナット８間の空間距離は、一方の端子固定用ナット８と第二の絶縁板５０の端子用貫通孔５４の側壁の回転電機３側の端部との最短距離、第二の絶縁板５０の回転電機３側の面５２の２つの端子用貫通孔５４間の長さおよび第二の絶縁板５０の端子用貫通孔５４の側壁の回転電機３側の端部と他方の端子固定用ナット８との最短距離を加算した長さとなる。この場合、図１２（ａ）に示した場合と比較して端子固定用ナット８間の空間距離は長くなる。 On the other hand, as shown in FIG. 12(b), in the third embodiment, a first insulating plate 4b and a second insulating plate 50 are used. A part of the terminal fixing nut 8 is exposed to the rotating electric machine 3 side through the notch 40 of the first insulating plate 4b, but the part exposed from the notch 40 is exposed to the side of the second insulating plate 50. It is located within the terminal through-hole 54 and is surrounded by the side wall of the terminal through-hole 54 . Therefore, the spatial distance between the terminal fixing nuts 8 is the shortest distance between one terminal fixing nut 8 and the end of the side wall of the terminal through hole 54 of the second insulating plate 50 on the side of the rotating electrical machine 3; The length between the two terminal through holes 54 on the surface 52 of the second insulating plate 50 on the rotating electric machine 3 side, and the length between the end of the side wall of the terminal through hole 54 on the rotating electric machine 3 side of the second insulating plate 50 and the other side. The length is the sum of the shortest distance to the terminal fixing nut 8. In this case, the spatial distance between the terminal fixing nuts 8 becomes longer than in the case shown in FIG. 12(a).

以上のように、実施の形態３における端子台１ｃは、第一の面である第一の絶縁板４ｂの回転電機３側の面２１ｂと接触する接触面である外部電源側の面５１と、外部電源側の面５１と対向する対向面である回転電機３側の面５２と、を有し、外部電源側の面５１から回転電機３側の面５２まで貫通する第二の複数の貫通孔である端子用貫通孔５４を有し、端子用貫通孔５４の各々に端子６を挿入可能である第二の絶縁板５０を備える。また、第二の絶縁板５０は、外部電源側の面５１に、第一の絶縁板４ｂの凹部２３と篏合する凸部５３を有することによって、第一の絶縁板４ｂに対する第二の絶縁板５０の位置決めが容易になる。さらに、第一の絶縁板４ｂに対する第二の絶縁板５０の位置ずれも防止することができる。 As described above, the terminal block 1c in the third embodiment has a surface 51 on the external power supply side, which is a contact surface that contacts the surface 21b on the rotating electrical machine 3 side of the first insulating plate 4b, which is the first surface, and A second plurality of through holes having a surface 51 on the external power source side and a surface 52 on the rotating electric machine 3 side which is an opposing surface, and penetrating from the surface 51 on the external power source side to the surface 52 on the rotating electric machine 3 side. A second insulating plate 50 is provided which has terminal through holes 54 and into which terminals 6 can be inserted. In addition, the second insulating plate 50 has a convex portion 53 on the surface 51 on the external power supply side that engages with the concave portion 23 of the first insulating plate 4b, thereby providing a second insulating plate with respect to the first insulating plate 4b. Positioning of the plate 50 becomes easy. Furthermore, it is also possible to prevent the second insulating plate 50 from being misaligned with respect to the first insulating plate 4b.

また、実施の形態３における端子台１ｃは、第二の絶縁板５０の外部電源側の面５１に平行な断面における端子用貫通孔５４の各々の形状は、導電性材料で形成された固定部材である端子固定用ナット８によって端子６と第一の絶縁板４ｂとが固定され、端子６が端子用貫通孔５４に挿入された状態において、端子固定用ナット８と端子用貫通孔５４の各々の側壁との間に空間を有するように形成される。これにより、第一の貫通孔１００に挿入された端子６に装着された端子固定用ナット８と第二の貫通孔１０１に挿入された端子６に装着された端子固定用ナット８との間の絶縁距離、特に空間距離を確保することができ、端子台１ｃを小型化することができる。 Further, in the terminal block 1c in the third embodiment, the shape of each terminal through hole 54 in a cross section parallel to the surface 51 on the external power supply side of the second insulating plate 50 is formed by a fixing member made of a conductive material. In a state where the terminal 6 and the first insulating plate 4b are fixed by the terminal fixing nut 8 and the terminal 6 is inserted into the terminal through hole 54, each of the terminal fixing nut 8 and the terminal through hole 54 is It is formed so as to have a space between it and the side wall. As a result, the distance between the terminal fixing nut 8 attached to the terminal 6 inserted into the first through hole 100 and the terminal fixing nut 8 attached to the terminal 6 inserted into the second through hole 101 is reduced. The insulation distance, especially the spatial distance, can be ensured, and the terminal block 1c can be downsized.

なお、実施の形態３では、凸部５３は第三の貫通孔１０３と第四の貫通孔１０４との間に線状の突起を作るように形成されているが、凸部５３の形状は線状の突起には限定されない。例えば、外部電源側から見た平面視において丸い形状や多角形の形状の凸部５３を形成してもよい。 In the third embodiment, the convex portion 53 is formed to form a linear protrusion between the third through hole 103 and the fourth through hole 104, but the convex portion 53 has a linear shape. It is not limited to shaped protrusions. For example, the convex portion 53 may have a round or polygonal shape when viewed from the external power source side.

さらに、実施の形態３では、第二の絶縁板５０の外部電源側の面５１の第三の貫通孔１０３と第四の貫通孔１０４との間に１つの凸部５３を設けたが、第二の絶縁板５０の外部電源側の面５１の第三の貫通孔１０３と第四の貫通孔１０４との間に２つ以上の凸部５３を設けてもよい。 Furthermore, in the third embodiment, one convex portion 53 is provided between the third through hole 103 and the fourth through hole 104 on the external power supply side surface 51 of the second insulating plate 50. Two or more convex portions 53 may be provided between the third through hole 103 and the fourth through hole 104 on the external power supply side surface 51 of the second insulating plate 50.

なお、実施の形態３では、図１１に示すように、平面視において円形状を有する端子用貫通孔５４を形成したが、端子用貫通孔５４の形状は、端子固定用ナット８によって端子６と第一の絶縁板４ｂとが固定され、端子６が端子用貫通孔５４に挿入された状態において、端子固定用ナット８と端子用貫通孔５４の側壁との間に空間を有するような形状であれば何でもよく、例えば平面視において長方形状や楕円状であってもよい。 In addition, in the third embodiment, as shown in FIG. 11, the terminal through hole 54 is formed to have a circular shape in plan view, but the shape of the terminal through hole 54 is such that the terminal 6 is connected to the terminal 6 by the terminal fixing nut 8. In a state where the first insulating plate 4b is fixed and the terminal 6 is inserted into the terminal through hole 54, the terminal is shaped such that there is a space between the terminal fixing nut 8 and the side wall of the terminal through hole 54. Any shape may be used, for example, it may be rectangular or elliptical in plan view.

なお、実施の形態３では、端子台１ｃに第一の絶縁板４ｂを用いたが、実施の形態１で示した第一の絶縁板４ａを用いてもよい。 Note that in the third embodiment, the first insulating plate 4b is used for the terminal block 1c, but the first insulating plate 4a shown in the first embodiment may also be used.
