　前記特許文献１に記載のバスバーは、前記第１及び第２プレートの積層構造、並びに、前記第１及び第２プレートの凸状形状によって、前記第１及び第２プレートの板厚方向に沿った衝撃（振動）を緩衝させることができる点において有用であるが、前記第１及び第２プレートの板面方向の衝撃（振動）については対応することができない。 The bus bar described in Patent Document 1 is along the thickness direction of the first and second plates due to the stacked structure of the first and second plates and the convex shape of the first and second plates. Although it is useful in that the impact (vibration) can be buffered, the impact (vibration) in the plate surface direction of the first and second plates cannot be dealt with.
　特に、前記バスバーにシャント抵抗が組み込まれる場合には、前記バスバーに衝撃（振動）が付加されると、前記シャント抵抗の溶接部に応力が集中し、微細な亀裂の発生による機能低下を招くと共に、場合によっては破断を招く虞がある。 In particular, when a shunt resistor is incorporated in the bus bar, if an impact (vibration) is applied to the bus bar, stress concentrates on the welded portion of the shunt resistor, resulting in functional deterioration due to the occurrence of fine cracks. In some cases, there is a risk of breakage.

In the figure, the same members as those in the present embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate.
　前記第２変形例１Ｃは、前記波状部３１の両側に一対の捻り部３５ａ、３５ｂが設けられている点においては本実施の形態と共通しているが、一対の捻り部３５ａ、３５ｂの捻り角が異なっている点において本実施の形態１Ａと相違している。 The second modification 1C is common to the present embodiment in that a pair of twisted portions 35a and 35b are provided on both sides of the wave-like portion 31, but the twist of the pair of twisted portions 35a and 35b is common. The difference from Embodiment 1A is that the corners are different.
　即ち、本実施の形態１Ａにおいては、前記一対の捻り部３５は捻り角が同一とされており、これにより、前記第１及び第２平面領域１０、２０が互いに対して平行とされている。 That is, in the present embodiment 1A, the pair of twisted portions 35 have the same twist angle, whereby the first and second planar regions 10 and 20 are parallel to each other.
　これに対し、前記第２変形例１Ｃにおいては、前記第１平面領域１０及び前記波状部３１の間に位置する第１捻り部３５ａの捻り角と、前記第２平面領域２０及び前記波状部３１の間に位置する第２捻り部３５ｂの捻り角とが異なっており、図１１に示すように、前記第１及び第２捻り部３５ａ、３５ｂでの捻り角度差に応じた角度で前記第１及び第２平面領域１０、２０が互いに対して傾斜されている。
　図示の形態においては、図１１に示すように、前記第１及び第２平面領域１０、２０は互いに対して直交配置されている。 On the other hand, in the second modified example 1C, the twist angle of the first twisted portion 35a located between the first plane region 10 and the waved portion 31, and the second plane region 20 and the waved portion 31 are included. The twist angle of the second twist portion 35b located between the first twist portion 35b and the second twist portion 35b is different from the twist angle of the first twist portion 35a, 35b as shown in FIG. And the second planar regions 10, 20 are inclined with respect to each other.
In the illustrated embodiment, as shown in FIG. 11, the first and second planar regions 10 and 20 are arranged orthogonal to each other.
　前記第１及び第２変形例に係るバスバー１Ｂ、１Ｃにおいても、前記第１及び第２平面領域１０、２０の板厚方向Ｖに沿った衝撃のみならず、前記第１及び第２平面領域１０、２０の板面方向（長手方向Ｌ及び幅方向Ｗ）に沿った衝撃も有効に緩衝することができる。
　従って、前記バスバー１Ｂ、１Ｃによって電気的に接続される二つの電気部材９０に衝撃又は振動が加わったとしても、前記バスバー１Ｂ、１Ｃによる前記二つの電気部材９０間の電気接続を良好に維持することができる。 Also in the bus bars 1B and 1C according to the first and second modified examples, not only the impact along the thickness direction V of the first and second planar regions 10 and 20 but also the first and second planar regions 10 are used. , The impact along the plate surface direction (longitudinal direction L and width direction W) can be effectively buffered.
Therefore, even if an impact or vibration is applied to the two electric members 90 electrically connected by the bus bars 1B and 1C, the electric connection between the two electric members 90 by the bus bars 1B and 1C is maintained well. be able to.
　前記中間領域３０に前記波状部３１を設け、縦断面視において前記波状部３１を前記第１及び第２平面領域１０、２０の少なくとも一方に対して傾斜させる前記構成は、シャント抵抗が備えられる場合に特に有効である。
　図１２に、シャント抵抗８０が備えられた、変形例に係るバスバー１Ａ’の斜視図を示す。 The configuration in which the corrugated portion 31 is provided in the intermediate region 30 and the corrugated portion 31 is inclined with respect to at least one of the first and second planar regions 10 and 20 in a longitudinal sectional view is provided with a shunt resistor. Is particularly effective.
FIG. 12 is a perspective view of a bus bar 1A ′ according to a modification in which the shunt resistor 80 is provided.
　図１２に示すように、前記バスバー１Ａ’は、前記第１平面領域１０、前記中間領域３０及び前記第２平面領域２０に加えて、前記第１及び第２平面領域１０、２０の少なくとも一方に介挿されたシャント抵抗８０と、前記シャント抵抗８０を挟んで長手方向両側に設けられた一対の検出端子８５とを有している。 As shown in FIG. 12, the bus bar 1 </ b> A ′ is formed in at least one of the first and second planar regions 10, 20 in addition to the first planar region 10, the intermediate region 30, and the second planar region 20. It has a shunt resistor 80 inserted and a pair of detection terminals 85 provided on both sides in the longitudinal direction across the shunt resistor 80.
　前記シャント抵抗８０は、予め抵抗値が測定されており、前記一対の検出端子８５間で測定される電圧値と前記シャント抵抗８０の抵抗値とに基づき、前記バスバー１Ａ’（即ち、前記バスバー１Ａ’によって連結される二つの電気部材９０間）を流れる電流値を算出する為に備えられるものである。 The shunt resistor 80 has a resistance value measured in advance. Based on the voltage value measured between the pair of detection terminals 85 and the resistance value of the shunt resistor 80, the bus bar 1A ′ (that is, the bus bar 1A It is provided for calculating the value of the current flowing between the two electric members 90 connected by '.
　前記シャント抵抗８０は溶接によって対応する平面領域（図１２においては第２平面領域２０）に接合されるが、図１２に示すように、前記中間領域３０に前記波状部３１を設け、前記板状部材の板厚方向に沿った縦断面視において前記波状部３１が前記第１及び第２平面領域１０、２０に対して傾斜するように構成することにより、前記第１及び第２平面領域１０、２０の板厚方向Ｖ及び板面方向（長手方向Ｌ及び幅方向Ｗ）の何れの方向に沿った衝撃又は振動が前記バスバー１Ａ’に付加されたとしても、前記シャント抵抗８０の溶接部分に応力が集中することを有効に防止することができる。 The shunt resistor 80 is joined to a corresponding planar region (second planar region 20 in FIG. 12) by welding. As shown in FIG. 12, the corrugated portion 31 is provided in the intermediate region 30, and the plate shape By configuring the corrugated portion 31 to be inclined with respect to the first and second planar regions 10 and 20 in a longitudinal sectional view along the plate thickness direction of the member, the first and second planar regions 10 and 20 Even if an impact or vibration along any one of the plate thickness direction V and the plate surface direction (longitudinal direction L and width direction W) is applied to the bus bar 1A ′, stress is applied to the welded portion of the shunt resistor 80. Can be effectively prevented from concentrating.
　従って、前記シャント抵抗付きのバスバー１Ａ’においては、当該バスバー１Ａ’及び／又は当該バスバー１Ａ’によって電気的に接続される二つの電気部材９０に衝撃又は振動が加わったとしても、前記衝撃又は振動に起因して前記シャント抵抗８０の溶接部に亀裂及び／又は破断が発生することを有効に防止することができる。 Accordingly, in the bus bar 1A ′ with a shunt resistor, even if an impact or vibration is applied to the bus bar 1A ′ and / or two electric members 90 electrically connected by the bus bar 1A ′, the shock or vibration It is possible to effectively prevent cracks and / or breakage from occurring in the welded portion of the shunt resistor 80 due to the above.
　これにより、前記衝撃又は振動によって、シャント抵抗機能、即ち、前記一対の検出端子８５間の電圧測定に基づき前記バスバー１Ａ’を流れる電流値を知る機能が損なわれることを有効に防止することができる。 Accordingly, it is possible to effectively prevent the impact or vibration from damaging the shunt resistance function, that is, the function of knowing the value of the current flowing through the bus bar 1A ′ based on the voltage measurement between the pair of detection terminals 85. .
　さらに、前記バスバー１Ａ’が温度上昇に伴って膨張したとしても、前記波状部３１が熱膨張を吸収することができるので、前記熱膨張によって前記シャント抵抗８０に応力が掛かることを有効に防止することもできる。 Furthermore, even if the bus bar 1A ′ expands as the temperature rises, the corrugated portion 31 can absorb thermal expansion, so that it is possible to effectively prevent stress from being applied to the shunt resistor 80 due to the thermal expansion. You can also.
