That is, a notch 101a is also formed between the recess 800 and the accommodating portion 101 on the upper surface 121 of the box-shaped portion 120 on the right side, and the inside of the two recesses 800 of the box-shaped portion 120 on the right side is formed through the notch 101a. Is filled with the filling resin 700.
　こうして、図１に示すようにフィルムコンデンサ１が完成する。 In this way, the film capacitor 1 is completed as shown in FIG.
　図５（ａ）、（ｂ）は、左側の箱状部１２０の上面１２１に形成された２つの凹部８００の近傍における断面図である。 5 (a) and 5 (b) are cross-sectional views in the vicinity of two recesses 800 formed on the upper surface 121 of the box-shaped portion 120 on the left side.
　図５（ａ）は、突部３２１の前後方向中央を通る上下方向および左右方向に平行な平面でフィルムコンデンサ１を切断したときの切断面を、前方から見た断面図である。図５（ｂ）は、右側の突部３２１の左右方向中央を通る上下方向および前後方向に平行な平面でフィルムコンデンサ１を切断したときの切断面を、右方から見た断面図である。なお、図５（ａ）に示す断面構成は、右側の箱状部１２０においても同様であり、図５（ｂ）に示す断面構成は、左側の突部３２１および２つの突部４２１においても同様である。 FIG. 5A is a cross-sectional view of the cut surface when the film capacitor 1 is cut in a plane parallel to the vertical direction and the horizontal direction passing through the center of the protrusion 321 in the front-rear direction, as viewed from the front. FIG. 5B is a cross-sectional view of the cut surface when the film capacitor 1 is cut in a plane parallel to the vertical direction and the front-rear direction passing through the center of the right-side protrusion 321 in the left-right direction, as viewed from the right. The cross-sectional structure shown in FIG. 5A is the same for the box-shaped portion 120 on the right side, and the cross-sectional structure shown in FIG. 5B is the same for the left protruding portion 321 and the two protruding portions 421. Is.
　図５（ａ）に示すように、凹部８００は、水平面に平行な底面８１０と、凹部８００の上端付近に形成された傾斜面８２１と、凹部８００の下端付近に形成された側面８２２と、を備える。凹部８００の内側面に傾斜面８２１が形成されることにより、凹部８００は、上端から下方に向かうにしたがって、凹部８００の水平面における幅が狭くなる。 As shown in FIG. 5A, the recess 800 includes a bottom surface 810 parallel to a horizontal plane, an inclined surface 821 formed near the upper end of the recess 800, and a side surface 822 formed near the lower end of the recess 800. Be prepared. By forming the inclined surface 821 on the inner side surface of the recess 800, the width of the recess 800 in the horizontal plane becomes narrower from the upper end to the lower side.
　また、凹部８００の後端と収容部１０１との間には、図４（ｂ）を参照して説明したように、切欠き１０１ａが形成されている。切欠き１０１ａは、凹部８００の内部と収容部１０１の内部とを接続する接続通路である。切欠き１０１ａが形成されることにより、収容部１０１に充填樹脂７００が液相状態で注入されると、収容部１０１内の充填樹脂７００が切欠き１０１ａを通って凹部８００内に流入する。 Further, as described with reference to FIG. 4B, a notch 101a is formed between the rear end of the recess 800 and the accommodating portion 101. The notch 101a is a connecting passage connecting the inside of the recess 800 and the inside of the accommodating portion 101. When the filling resin 700 is injected into the accommodating portion 101 in a liquid phase state due to the formation of the notch 101a, the filling resin 700 in the accommodating portion 101 flows into the recess 800 through the notch 101a.
　図５（ｂ）に示すように、凹部８００は、切欠き１０１ａの下方に、切欠き１０１ａの下端から下方に形成された傾斜面８３１と、凹部８００の下端付近に形成された側面８３２と、を備える。切欠き１０１ａの下方に傾斜面８３１が形成されることにより、凹部８００は、切欠き１０１ａの下端から下方に向かうにしたがって、凹部８００の水平面における幅が狭くなる。傾斜面８２１、８３１が形成されることにより、図３に示したように、コンデンサ素子ユニット１ａがケース１００の収容部１０１内に収容される際に、突部３２１、４２１を円滑に凹部８００内に挿入できる。これにより、第１バスバー３００の接続孔３２２に接続端子部５２０を円滑に挿入でき、第２バスバー４００の接続孔４２２に接続端子部６２０を円滑に挿入できる。 As shown in FIG. 5B, the recess 800 includes an inclined surface 831 formed below the notch 101a from the lower end of the notch 101a and a side surface 832 formed near the lower end of the recess 800. To prepare for. By forming the inclined surface 831 below the notch 101a, the width of the recess 800 in the horizontal plane of the recess 800 becomes narrower from the lower end of the notch 101a toward the lower side. By forming the inclined surfaces 821 and 831, as shown in FIG. 3, when the capacitor element unit 1a is housed in the housing portion 101 of the case 100, the protrusions 321 and 421 are smoothly inserted in the recess 800. Can be inserted into. As a result, the connection terminal portion 520 can be smoothly inserted into the connection hole 322 of the first bus bar 300, and the connection terminal portion 620 can be smoothly inserted into the connection hole 422 of the second bus bar 400.
　次に、図１を参照して、フィルムコンデンサ１と外部装置との接続について説明する。 Next, the connection between the film capacitor 1 and the external device will be described with reference to FIG.
　フィルムコンデンサ１は、たとえば、電気自動車において電気モータを駆動するためのインバータ装置に搭載される。インバータ装置には、電源装置（バッテリー）から直流の電力が供給される。インバータ装置は、ＩＧＢＴ（Insulated Gate Bipolar Transistor）を含むインバータ回路を備え、直流の電力を３相交流の電力に変換し、電気モータへ供給する。 The film capacitor 1 is mounted on, for example, an inverter device for driving an electric motor in an electric vehicle. DC power is supplied to the inverter device from the power supply device (battery). The inverter device includes an inverter circuit including an IGBT (Insulated Gate Bipolar Transistor), converts direct current power into three-phase alternating power, and supplies it to an electric motor.
　第１バスバー３００の外部接続端子部３１０には、対応する外部装置（電源装置およびインバータ装置）の外部端子が、取付孔３１１を用いたネジ止めにより接続される。同様に、第２バスバー４００の外部接続端子部４１０には、対応する外部装置（電源装置および電源モータ）の外部端子が、取付孔４１１を用いたネジ止めにより接続される。 The external terminals of the corresponding external devices (power supply device and inverter device) are connected to the external connection terminal portion 310 of the first bus bar 300 by screwing using the mounting holes 311. Similarly, the external terminals of the corresponding external devices (power supply device and power supply motor) are connected to the external connection terminal portion 410 of the second bus bar 400 by screwing using the mounting holes 411.
　また、第１端子５００の外部接続端子部５１０および第２端子６００の外部接続端子部６１０には、コンデンサ素子２００の電圧値を監視するための外部装置の外部端子が、半田付け等の接合方法により接続される。フィルムコンデンサ１の通電時、コンデンサ素子２００の電圧が電圧信号として、接続端子部３２０、４２０を介して、信号出力端子である外部接続端子部５１０、６１０から外部装置に出力される。これにより、外部装置に含まれる、電圧信号を監視するための監視装置において、コンデンサ素子２００の電圧を検出し、監視することが可能となる。 Further, an external terminal of an external device for monitoring the voltage value of the capacitor element 200 is attached to the external connection terminal portion 510 of the first terminal 500 and the external connection terminal portion 610 of the second terminal 600 by a joining method such as soldering. Connected by. When the film capacitor 1 is energized, the voltage of the capacitor element 200 is output as a voltage signal from the external connection terminal portions 510 and 610, which are signal output terminals, to the external device via the connection terminal portions 320 and 420. This makes it possible to detect and monitor the voltage of the capacitor element 200 in the monitoring device for monitoring the voltage signal included in the external device.
　＜実施の形態の効果＞
　以上、本実施の形態によれば、以下の効果が奏される。 <Effect of embodiment>
As described above, according to the present embodiment, the following effects are achieved.
　第１バスバー３００は、電極端子部３３０および接続端子部３２０を備え、電極端子部３３０は、コンデンサ素子２００の第１電極２１０に接続される。第２バスバー４００は、電極端子部４３０および接続端子部４２０を備え、電極端子部４３０は、コンデンサ素子２００の第２電極２２０に接続される。接続端子部３２０は、収容部１０１の外部（上方）に位置付けられるとともに突部３２１を有する。接続端子部４２０は、収容部１０１の外部（上方）に位置付けられるとともに突部４２１を有する。ケース１００は、突部３２１、４２１が挿入される凹部８００を有する。 The first bus bar 300 includes an electrode terminal portion 330 and a connection terminal portion 320, and the electrode terminal portion 330 is connected to the first electrode 210 of the capacitor element 200. The second bus bar 400 includes an electrode terminal portion 430 and a connection terminal portion 420, and the electrode terminal portion 430 is connected to the second electrode 220 of the capacitor element 200. The connection terminal portion 320 is positioned outside (above) the accommodating portion 101 and has a protrusion 321. The connection terminal portion 420 is positioned outside (above) the accommodating portion 101 and has a protrusion 421. The case 100 has a recess 800 into which the protrusions 321 and 421 are inserted.
　この構成によれば、凹部８００に突部３２１、４２１を挿入することにより、第１バスバー３００および第２バスバー４００をケース１００に対して設置できる。これにより、第１バスバー３００および第２バスバー４００をケース１００に対して簡易に設置できる。 According to this configuration, the first bus bar 300 and the second bus bar 400 can be installed on the case 100 by inserting the protrusions 321 and 421 into the recess 800. As a result, the first bus bar 300 and the second bus bar 400 can be easily installed on the case 100.
　ここで、本実施の形態では、第１バスバー３００の接続端子部３２０および第２バスバー４００の接続端子部４２０は、コンデンサ素子２００の電圧値を監視するための外部装置へ電圧値を中継するために設けられている。したがって、本実施の形態の本体部３２０ａ、４２０ａ（図２参照）は、左右方向の幅が狭くなるよう構成されている。このように本体部３２０ａ、４２０ａの左右方向の幅が狭くなると、接続端子部３２０、４２０をケース１００に設置するための嵌合孔を本体部３２０ａ、４２０ａに設けるのが困難になる。これに対し、本実施の形態では、接続端子部３２０の左右に突部３２１が設けられ、接続端子部４２０の左右に突部４２１が設けられている。これにより、本体部３２０ａ、４２０ａの左右方向の幅が狭くても、突部３２１、４２１を凹部８００に挿入することにより、接続端子部３２０、４２０をケース１００に設置できる。 Here, in the present embodiment, the connection terminal portion 320 of the first bus bar 300 and the connection terminal portion 420 of the second bus bar 400 relay the voltage value to an external device for monitoring the voltage value of the capacitor element 200. It is provided in. Therefore, the main body portions 320a and 420a (see FIG. 2) of the present embodiment are configured to have a narrow width in the left-right direction. When the widths of the main bodies 320a and 420a in the left-right direction are narrowed in this way, it becomes difficult to provide fitting holes for installing the connection terminal portions 320 and 420 in the case 100 in the main bodies 320a and 420a. On the other hand, in the present embodiment, protrusions 321 are provided on the left and right sides of the connection terminal portion 320, and protrusions 421 are provided on the left and right sides of the connection terminal portion 420. As a result, even if the widths of the main bodies 320a and 420a in the left-right direction are narrow, the connection terminal portions 320 and 420 can be installed in the case 100 by inserting the protrusions 321 and 421 into the recess 800.
　なお、電気抵抗の増加を抑制するために、左右方向の幅が広くなるよう本体部３２０ａ、４２０ａが構成された場合、本体部３２０ａ、４２０ａに嵌合穴が設けられると電気抵抗が増加してしまう。したがって、この場合も、嵌合穴を本体部３２０ａ、４２０ａに設けるのが困難となる。これに対し、本実施の形態によれば、接続端子部３２０、４２０にそれぞれ突部３２１、４２１が設けられることにより、電気抵抗の増加を抑制しながら、接続端子部３２０、４２０をケース１００に設置できる。 In addition, when the main body portions 320a and 420a are configured so that the width in the left-right direction becomes wide in order to suppress the increase in the electric resistance, the electric resistance increases when the fitting holes are provided in the main body portions 320a and 420a. It ends up. Therefore, in this case as well, it is difficult to provide the fitting holes in the main body portions 320a and 420a. On the other hand, according to the present embodiment, the connection terminal portions 320 and 420 are provided with the protrusions 321 and 421, respectively, so that the connection terminal portions 320 and 420 are placed in the case 100 while suppressing an increase in electrical resistance. Can be installed.
　突部３２１は、接続端子部３２０の一部が折り曲げられることにより形成され、突部４２１は、接続端子部４２０の一部が折り曲げられることにより形成される。 The protrusion 321 is formed by bending a part of the connection terminal portion 320, and the protrusion 421 is formed by bending a part of the connection terminal portion 420.
　この構成によれば、接続端子部３２０、４２０の幅が狭い場合でも、第１バスバー３００に突部３２１を簡易に形成でき、第２バスバー４００に突部４２１を簡易に形成できる。 According to this configuration, even when the widths of the connection terminal portions 320 and 420 are narrow, the protrusion 321 can be easily formed on the first bus bar 300, and the protrusion 421 can be easily formed on the second bus bar 400.
　凹部８００は、上端（入口部）から下方（内部）に向かうにしたがって、凹部８００の幅が狭くなるように傾斜面８２１、８３１を有する。 The recess 800 has inclined surfaces 821 and 831 so that the width of the recess 800 becomes narrower from the upper end (entrance portion) toward the lower side (inside).
　この構成によれば、突部３２１、４２１を傾斜面８２１、８３１に沿って凹部８００の内部へと円滑に挿入できる。 According to this configuration, the protrusions 321 and 421 can be smoothly inserted into the recess 800 along the inclined surfaces 821 and 831.
　第１端子５００は、ケース１００にインサート成形され、外部接続端子部５１０（第１端子５００の一端）は、外部に引き出されている。第２端子６００は、ケース１００にインサート成形され、外部接続端子部６１０（第２端子６００の一端）は、外部に引き出されている。第１バスバー３００の接続端子部３２０は、突部３２１が凹部８００に挿入されたときに、接続端子部５２０（第１端子５００の他端）に接続可能な位置に位置付けられるよう構成される。第２バスバー４００の接続端子部４２０は、突部４２１が凹部８００に挿入されたときに、接続端子部６２０（第２端子６００の他端）に接続可能な位置に位置付けられるよう構成される。 The first terminal 500 is insert-molded into the case 100, and the external connection terminal portion 510 (one end of the first terminal 500) is pulled out to the outside. The second terminal 600 is insert-molded into the case 100, and the external connection terminal portion 610 (one end of the second terminal 600) is pulled out to the outside. The connection terminal portion 320 of the first bus bar 300 is configured to be positioned at a position where it can be connected to the connection terminal portion 520 (the other end of the first terminal 500) when the protrusion 321 is inserted into the recess 800. The connection terminal portion 420 of the second bus bar 400 is configured to be positioned at a position where it can be connected to the connection terminal portion 620 (the other end of the second terminal 600) when the protrusion 421 is inserted into the recess 800.
　この構成によれば、突部３２１、４２１を凹部８００に挿入して第１バスバー３００および第２バスバー４００をケース１００に対して設置することにより、第１バスバー３００の接続端子部３２０および第１端子５００の接続端子部５２０の位置を一致させることができ、第２バスバー４００の接続端子部４２０および第２端子６００の接続端子部６２０の位置を一致させることができる。よって、第１バスバー３００と第１端子５００との接続および第２バスバー４００と第２端子６００との接続を円滑に行うことができる。 According to this configuration, by inserting the protrusions 321 and 421 into the recess 800 and installing the first bus bar 300 and the second bus bar 400 with respect to the case 100, the connection terminal portions 320 and the first bus bar 300 of the first bus bar 300 are installed. The positions of the connection terminal portion 520 of the terminal 500 can be matched, and the positions of the connection terminal portion 420 of the second bus bar 400 and the connection terminal portion 620 of the second terminal 600 can be matched. Therefore, the connection between the first bus bar 300 and the first terminal 500 and the connection between the second bus bar 400 and the second terminal 600 can be smoothly performed.
　第１バスバー３００の接続端子部３２０は、第１端子５００の接続端子部５２０を挿入可能な接続孔３２２を有し、第２バスバー４００の接続端子部４２０は、第２端子６００の接続端子部６２０を挿入可能な接続孔４２２を有する。接続孔３２２は、突部３２１が凹部８００に挿入されたときに接続端子部５２０（第１端子５００の他端）に挿入される位置に設けられ、接続孔４２２は、突部４２１が凹部８００に挿入されたときに接続端子部６２０（第２端子６００の他端）が挿入される位置に設けられる。 The connection terminal portion 320 of the first bus bar 300 has a connection hole 322 into which the connection terminal portion 520 of the first terminal 500 can be inserted, and the connection terminal portion 420 of the second bus bar 400 has a connection terminal portion of the second terminal 600. It has a connection hole 422 into which a 620 can be inserted. The connection hole 322 is provided at a position where the protrusion 321 is inserted into the connection terminal portion 520 (the other end of the first terminal 500) when the protrusion 321 is inserted into the recess 800, and the connection hole 422 has the protrusion 421 of the recess 800. It is provided at a position where the connection terminal portion 620 (the other end of the second terminal 600) is inserted when it is inserted into.
　この構成によれば、突部３２１、４２１を凹部８００に挿入して、第１バスバー３００および第２バスバー４００をケース１００に対して設置することにより、接続孔３２２および接続端子部５２０の位置を一致させることができ、接続孔４２２および接続端子部６２０の位置を一致させることができる。よって、第１バスバー３００と第１端子５００との接続および第２バスバー４００と第２端子６００との接続を、確実かつ円滑に行うことができる。 According to this configuration, by inserting the protrusions 321 and 421 into the recess 800 and installing the first bus bar 300 and the second bus bar 400 with respect to the case 100, the positions of the connection hole 322 and the connection terminal portion 520 can be determined. It can be matched, and the positions of the connection hole 422 and the connection terminal portion 620 can be matched. Therefore, the connection between the first bus bar 300 and the first terminal 500 and the connection between the second bus bar 400 and the second terminal 600 can be surely and smoothly performed.

By filling 700, it is fixed to the recess 800.
　この構成によれば、第１バスバー３００および第２バスバー４００をケース１００に対して確実に固定することができる。 According to this configuration, the first bus bar 300 and the second bus bar 400 can be securely fixed to the case 100.
　ケース１００は、コンデンサ素子２００を収容する収容部１０１と、凹部８００とを接続する切欠き１０１ａ（接続通路）を備える。突部３２１、４２１は、コンデンサ素子２００と収容部１０１との間に充填された充填樹脂７００が切欠き１０１ａを介して凹部８００に充填されることにより、凹部８００に対して固定される。 The case 100 includes a notch 101a (connection passage) for connecting the accommodating portion 101 accommodating the capacitor element 200 and the recess 800. The protrusions 321 and 421 are fixed to the recess 800 by filling the recess 800 with the filling resin 700 filled between the capacitor element 200 and the accommodating portion 101 via the notch 101a.

It can be fixed smoothly.
　以上、本発明の実施の形態について説明したが、本発明は、上記実施の形態に限定されるものではなく、また、本発明の適用例も、上記実施の形態の他に、種々の変更が可能である。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and the application examples of the present invention may be changed in various ways in addition to the above embodiments. It is possible.
　＜変更例１＞
　上記実施の形態では、凹部８００に傾斜面８２１、８３１が設けられたが、変更例１では、突部３２１、４２１に傾斜面が設けられる。 <Change example 1>
In the above embodiment, the recesses 800 are provided with inclined surfaces 821 and 831, but in the first modification, the protrusions 321 and 421 are provided with inclined surfaces.
　図６（ａ）、（ｂ）は、変更例１に係る、左側の箱状部１２０の上面１２１に形成された凹部８００の近傍における断面図である。図６（ａ）、（ｂ）は、それぞれ、図５（ａ）、（ｂ）と同様の断面図である。 6 (a) and 6 (b) are cross-sectional views in the vicinity of the recess 800 formed on the upper surface 121 of the left box-shaped portion 120 according to the first modification. 6 (a) and 6 (b) are cross-sectional views similar to those of FIGS. 5 (a) and 5 (b), respectively.
　変更例１では、図６（ａ）に示すように、突部３２１の左右の側面に傾斜面３２１ａが形成され、図６（ｂ）に示すように、突部３２１の前後の側面に傾斜面３２１ｂが形成される。これにより、接続端子部３２０に設けられた突部３２１の断面は、下方に進むにつれて左右方向および前後方向の幅が小さくなるよう構成される。また、上記実施の形態と比較して、凹部８００の側面から傾斜面が省略され、側面８２２、８３２が上方向に延びている。変更例１では、２つの突部４２１と、２つの突部４２１に対応する２つの凹部８００も、図６（ａ）、（ｂ）と同様に構成される。 In the first modification, as shown in FIG. 6A, inclined surfaces 321a are formed on the left and right side surfaces of the protrusion 321 and as shown in FIG. 6B, inclined surfaces are formed on the front and rear side surfaces of the protrusion 321. 321b is formed. As a result, the cross section of the protrusion 321 provided on the connection terminal portion 320 is configured so that the width in the left-right direction and the width in the front-rear direction becomes smaller as it goes downward. Further, as compared with the above embodiment, the inclined surface is omitted from the side surface of the recess 800, and the side surfaces 822 and 832 extend upward. In the first modification, the two protrusions 421 and the two recesses 800 corresponding to the two protrusions 421 are also configured in the same manner as in FIGS. 6A and 6B.
　変更例１においても、突部３２１、４２１に傾斜面が形成されることにより、突部３２１、４２１は、上端から下方に向かうにしたがって幅が狭くなっている。これにより、突部３２１、４２１を凹部８００の内部へと円滑に挿入できる。 Also in the first modification, the width of the protrusions 321 and 421 becomes narrower from the upper end to the lower side due to the formation of the inclined surface on the protrusions 321 and 421. As a result, the protrusions 321 and 421 can be smoothly inserted into the recess 800.
　なお、上記実施の形態および変更例１では、突部３２１、４２１と凹部８００のいずれか一方に傾斜面が設けられたが、両方に傾斜面が設けられてもよい。また、突部３２１、４２１および凹部８００に設ける傾斜面に代えて、幅が下方に進むにつれて段階的に狭くなるよう、断面が階段状の面が形成されてもよい。 In the above-described embodiment and modification 1, an inclined surface is provided on either one of the protrusions 321 and 421 and the recess 800, but an inclined surface may be provided on both of them. Further, instead of the inclined surfaces provided in the protrusions 321 and 421 and the recess 800, a surface having a stepped cross section may be formed so that the width gradually narrows as the width advances downward.

　図７（ａ）は、変更例２に係る、左側の箱状部１２０の近傍の上面図である。なお、右側の箱状部１２０の近傍の構成も同様であるため、以下、左側の箱状部１２０の近傍の構成についてのみ説明する。 FIG. 7A is a top view of the vicinity of the box-shaped portion 120 on the left side according to the second modification. Since the configuration in the vicinity of the box-shaped portion 120 on the right side is the same, the configuration in the vicinity of the box-shaped portion 120 on the left side will be described below.
　図７（ａ）に示すように、変更例２では、接続端子部３２０の本体部３２０ａの下面に、２つの突部３２１が間隔を開けて形成されている。これにより、２つの突部３２１の左右方向における中心間の距離は、上記実施の形態よりも短くなる。したがって、変更例２では、２つの凹部８００の中心間の距離が上記実施の形態よりも短くなるよう、２つの凹部８００が、左側の箱状部１２０の上面１２１に形成される。 As shown in FIG. 7A, in the second modification, two protrusions 321 are formed at intervals on the lower surface of the main body 320a of the connection terminal 320.

　図７（ｂ）は、変更例３に係る、左側の箱状部１２０の近傍の上面図である。なお、右側の箱状部１２０の近傍の構成も同様であるため、以下、左側の箱状部１２０の近傍の構成についてのみ説明する。 FIG. 7B is a top view of the vicinity of the box-shaped portion 120 on the left side according to the modified example 3. Since the configuration in the vicinity of the box-shaped portion 120 on the right side is the same, the configuration in the vicinity of the box-shaped portion 120 on the left side will be described below.
　図７（ｂ）に示すように、変更例３では、２つの突部３２１と接続孔３２２との間に、さらに突部３２３が形成されている。突部３２３は、本体部３２０ａの下面に溶接等により接合されている。突部３２３は、突部３２１と同様の形状を有し、上下方向および左右方向に平行な面を有する。また、変更例３では、突部３２３の下方において、箱状部１２０の上面１２１に凹部９００が形成されている。凹部９００は、凹部８００と同様の形状を有する。 As shown in FIG. 7B, in the modified example 3, a protrusion 323 is further formed between the two protrusions 321 and the connection hole 322. The protrusion 323 is joined to the lower surface of the main body 320a by welding or the like. The protrusion 323 has the same shape as the protrusion 321 and has planes parallel to the vertical and horizontal directions. Further, in the third modification, a recess 900 is formed on the upper surface 121 of the box-shaped portion 120 below the protrusion 323. The recess 900 has the same shape as the recess 800.

After that, the accommodating portion 101 is filled with the filling resin 700, so that the accommodating portion 101 and the recess 800 are filled with the filling resin 700. Further, the recess 900 is also separately filled with the filling resin 700.
　変更例３によれば、２つの突部３２１を２つの凹部８００に挿入し、さらに突部３２３を凹部９００に挿入することにより、第１バスバー３００をケース１００に対して、さらに強固に設置できる。右側の箱状部１２０についても同様に、３つの突部が３つの凹部に挿入されることにより、第２バスバー４００をケース１００に対して、さらに強固に設置できる。 According to the third modification, the first bus bar 300 can be installed more firmly with respect to the case 100 by inserting the two protrusions 321 into the two recesses 800 and further inserting the protrusions 323 into the recesses 900. ..

　なお、変更例３では、凹部９００は収容部１０１に繋がっていないため、突部３２３を固定する際に、別途、充填樹脂７００を凹部９００に充填する必要がある。したがって、変更例３において、凹部９００と凹部８００とを接続する切欠きを設け、収容部１０１への充填樹脂７００の充填に応じて、凹部９００にも充填樹脂７００が充填されるようにしてもよい。 In the third modification, since the recess 900 is not connected to the accommodating portion 101, it is necessary to separately fill the recess 900 with the filling resin 700 when fixing the protrusion 323. Therefore, in the third modification, a notch connecting the recess 900 and the recess 800 is provided so that the recess 900 is also filled with the filling resin 700 according to the filling of the accommodating portion 101 with the filling resin 700. good.
