Description

本発明は、電源回路部材およびバスバに関する。 The present invention relates to a power supply circuit component and a bus bar.

車両に配索されるワイヤハーネスにおいて、当該ワイヤハーネスを構成する幹線導体の途中に枝線導体を分岐接続するに当たり、枝線導体の端部に圧接スロットを有する端子部を設け、その端子部を幹線導体に圧接により接続するものがある（例えば、特許文献１参照）。 In some wire harnesses installed in vehicles, when a branch conductor is branched and connected to the trunk conductor that constitutes the wire harness, a terminal portion having a pressure-welding slot is provided at the end of the branch conductor, and the terminal portion is connected to the trunk conductor by pressure welding (see, for example, Patent Document 1).

一方、車両に搭載される電気接続箱では、電源回路などを構成する幹線導体として、バスバを用いることが広く行われている。電源回路をバスバで構成する場合、バスバの一端に形成した端子部を電源側の締結対象部材にネジで締結し、バスバの他端に形成した端子部を負荷側の締結対象部材にネジで締結することが一般的によく行われている。 On the other hand, in electrical junction boxes mounted on vehicles, bus bars are widely used as main conductors that constitute power circuits, etc. When a power circuit is constituted by a bus bar, it is common practice to fasten a terminal portion formed at one end of the bus bar to a fastening target member on the power supply side with a screw, and fasten a terminal portion formed at the other end of the bus bar to a fastening target member on the load side with a screw.

ところで、前述の電源回路を構成するバスバに外部電線を分岐接続する場合には、特許文献１に示すような圧接による方法を採用することは困難であり、一般的には、バスバの端部の端子部を締結対象部材にネジで締結する際に、電線の端末に設けた端子部も一緒に同じネジよって共締めすることが行われている。 However, when branching and connecting an external electric wire to the bus bar that constitutes the power supply circuit described above, it is difficult to adopt the method of crimping as shown in Patent Document 1, and generally, when fastening the terminal portion at the end of the bus bar to the fastening target member with a screw, the terminal portion provided at the end of the electric wire is also fastened together with the same screw.

しかし、既に両端が締結対象部材にネジで締結されているバスバに対して、後から外部電線を分岐接続しようとする場合、既に締結に用いているネジをいったん取り外した上で、改めて外部電線の端子部を同じネジで共締めするのは作業が面倒である。 However, when trying to branch and connect an external electric wire to a bus bar whose both ends are already fastened to the fastening target components with screws, it is cumbersome to first remove the screws already used for fastening and then refasten the terminal part of the external electric wire with the same screws.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、既に両端の締結部が締結対象部材に締結されているバスバに対しても、締結を解除しないで、後から容易に外部電線を分岐接続することのできる電源回路部材およびバスバを提供することにある。 The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a power supply circuit component and a bus bar that allows easy branch connection of external electric wires to a bus bar whose fastening portions at both ends have already been fastened to fastening target members without releasing the fastening.

前述した目的を達成するために、本発明に係る電源回路部材およびバスバは、下記（１）～（４）を特徴としている。
（１）帯板よりなり、延在方向の両端に取付対象部材に対する締結部を有するバスバと、
前記バスバの延在形状に沿って形成されて前記バスバを収容する樹脂製のハウジングと、
を備える電源回路部材であって、
前記バスバは、前記帯板の板面に平行な面内で屈曲された第１の屈曲部および第２の屈曲部と、前記第１の屈曲部および第２の屈曲部の間の直線部とを有し、
前記直線部における前記バスバの側縁部に、外部電線とのコネクタ接続が可能な電線接続端子部が設けられ、
前記電線接続端子部は、
前記第１の屈曲部から一端側の前記締結部へ向かう延在方向に延在する直線部、及び、前記第２の屈曲部から他端側の前記締結部へ向かう延在方向に延在する直線部のうち、一方側の延在方向に延在する直線部と平行な方向に向けて設けられる、
電源回路部材。 In order to achieve the above-mentioned object, a power supply circuit member and a bus bar according to the present invention are characterized by the following (1) to (4).
(1) A bus bar made of a strip plate and having fastening portions for fastening to a target member at both ends in an extension direction;
a resin housing formed along an extension shape of the bus bar and accommodating the bus bar;
A power supply circuit member comprising:
the bus bar has a first bent portion and a second bent portion bent in a plane parallel to a plate surface of the band plate, and a straight portion between the first bent portion and the second bent portion,
a wire connection terminal portion that can be connected to an external wire via a connector is provided on a side edge portion of the bus bar in the straight portion ,

Power supply circuit components.

上記（１）の構成の電源回路部材によれば、バスバの両端の締結部の中間に、外部電線とのコネクタ接続が可能な電線接続端子部が設けられているので、両端の締結部の締結を解除することなく、バスバに対し外部電線を分岐接続することができる。したがって、後から電源回路の分岐の必要が生じた場合にも、単にバスバに設けた電線接続端子部に外部電線をコネクタ接続するだけで簡単に実現できる。また、バスバが複数の屈曲部を有しているので、屈曲部が形成される位置を調整することにより、締結対象のバリエーションに応じたバスバの配索を実現できると共に、両屈曲部間の直線部に設けられた電線接続端子部の位置の調節も容易になる。 According to the power supply circuit member of the configuration (1) above, a wire connection terminal portion capable of connecting to an external electric wire is provided between the fastening portions at both ends of the bus bar, so that an external electric wire can be branched and connected to the bus bar without releasing the fastening portions at both ends. Therefore, even if the need for branching of the power supply circuit arises later, this can be easily achieved by simply connecting the external electric wire to the wire connection terminal portion provided on the bus bar. In addition, since the bus bar has multiple bends, by adjusting the positions at which the bends are formed, the bus bar can be arranged in accordance with the variety of fastening objects, and the position of the wire connection terminal portion provided on the straight portion between the two bends can also be easily adjusted.

（２）前記電線接続端子部として、前記第１の屈曲部および第２の屈曲部の間の直線部における前記バスバの側縁部に、電線接続端子片が突設されており、

The housing is formed with a connector housing portion that receives the electric wire connection terminal piece and forms a connector that can be fitted with a connector of the external electric wire.
The power supply circuit component described in (1) above.

上記（２）の構成の電源回路部材によれば、バスバに設けた電線接続端子片をコネクタハウジング部で収容して外部電線と接続するためのコネクタを形成しているので、外部電線の接続および接続解除も安全かつ容易にでき、不使用時には、電線接続端子片を外部に露出しないように保護することができて安全性を確保することができる。 According to the power supply circuit component of the configuration (2) above, the electric wire connection terminal piece provided on the bus bar is housed in the connector housing to form a connector for connecting to an external electric wire, so that the external electric wire can be safely and easily connected and disconnected, and when not in use, the electric wire connection terminal piece can be protected from exposure to the outside, ensuring safety.

（３）帯板よりなり、延在方向の両端に取付対象部材に対する締結部を有するバスバと、
前記バスバの延在形状に沿って形成されて前記バスバを収容する樹脂製のハウジングと、
を備える電源回路部材であって、
前記バスバは、前記帯板の板面に平行な面内で屈曲された第１の屈曲部および第２の屈曲部と、前記第１の屈曲部および第２の屈曲部の間の直線部とを有し、
前記直線部における前記バスバの側縁部に、外部電線とのコネクタ接続が可能な電線接続端子部が設けられ、
前記電線接続端子部として、前記直線部における前記バスバの側縁部に、電線接続端子片が突設されており、
前記ハウジングに、前記電線接続端子片を収容して前記外部電線のコネクタと嵌合可能なコネクタを形成するコネクタハウジング部が形成され、
前記第１の屈曲部と第２の屈曲部は、前記直線部から見て反対方向に直角に屈曲しており、
前記電線接続端子片は、前記直線部における前記バスバの側縁部に、前記直線部の延在方向に対して垂直方向に突設され、
当該電線接続端子片に対して、前記外部電線のコネクタの端子が、前記直線部の延在方向に垂直な方向に着脱自在とされている、
電源回路部材。 (3) A bus bar made of a strip and having fastening portions for fastening to a target member at both ends in an extension direction;
a resin housing formed along an extension shape of the bus bar and accommodating the bus bar;
A power supply circuit member comprising:
the bus bar has a first bent portion and a second bent portion bent in a plane parallel to a plate surface of the band plate, and a straight portion between the first bent portion and the second bent portion,
a wire connection terminal portion that can be connected to an external wire via a connector is provided on a side edge portion of the bus bar in the straight portion,
As the electric wire connection terminal portion, an electric wire connection terminal piece is provided to protrude from a side edge portion of the bus bar in the straight portion,
a connector housing portion that receives the electric wire connection terminal piece and forms a connector that can be fitted with a connector of the external electric wire,
the first bent portion and the second bent portion are bent at right angles in opposite directions as viewed from the straight portion,
the electric wire connection terminal piece is provided on a side edge portion of the bus bar in the straight portion so as to protrude in a direction perpendicular to an extending direction of the straight portion,
A terminal of the connector of the external electric wire is detachably attached to the electric wire connection terminal piece in a direction perpendicular to the extending direction of the straight portion .
Power supply circuit components .

上記（３）の構成の電源回路部材によれば、バスバの電線接続端子片にコネクタ接続した外部電線の延びる方向を、両屈曲部間の直線部と垂直な方向に設定できるので、バスバと外部電線との相互干渉をできるだけ抑制することができる。また、バスバの電線接続端子片にコネクタ接続した外部電線を、屈曲部から端部に延びるバスバの延在方向と平行な方向に引き延ばすことができるので、バスバと外部電線の配索領域をコンパクトに収めることができる。また、外部電線が接続されていない状態でも、電線接続端子片が、バスバの両屈曲部間の直線部から、バスバの端部と屈曲部との間におけるバスバの延在方向に沿った方向に突出しているので、屈曲部から端部に向けて延びるバスバの部分を「袖」と見立てると、電線接続端子片が袖の内側に隠れて存在するような形になり、バスバを配索する際の邪魔になりにくい。 According to the power supply circuit member having the configuration of (3) above, the direction in which the external electric wire connected to the electric wire connection terminal piece of the bus bar extends can be set perpendicular to the straight portion between the two bent portions, so that mutual interference between the bus bar and the external electric wire can be suppressed as much as possible. In addition, the external electric wire connected to the electric wire connection terminal piece of the bus bar can be extended in a direction parallel to the extension direction of the bus bar extending from the bent portion to the end portion, so that the wiring area of the bus bar and the external electric wire can be compactly stored. In addition, even when the external electric wire is not connected, the electric wire connection terminal piece protrudes from the straight portion between the two bent portions of the bus bar in the direction along the extension direction of the bus bar between the end portion of the bus bar and the bent portion of the bus bar. If the portion of the bus bar extending from the bent portion to the end portion is considered as a "sleeve," the electric wire connection terminal piece is hidden inside the sleeve, and is unlikely to get in the way when wiring the bus bar.

（４）帯板よりなり、延在方向の両端に取付対象部材に対する締結部を有し、
前記帯板の板面に平行な面内で屈曲された第１の屈曲部および第２の屈曲部と、前記第１の屈曲部および第２の屈曲部の間の直線部とを有し、
前記直線部における前記帯板の側縁部に、外部電線との接続が可能な電線接続端子片が突設され、
前記電線接続端子片は、
前記第１の屈曲部から一端側の前記締結部へ向かう延在方向に延在する直線部、及び、前記第２の屈曲部から他端側の前記締結部へ向かう延在方向に延在する直線部のうち、一方側の延在方向に延在する直線部と平行な方向に向けて設けられる、
バスバ。 (4) The plate is made of a strip and has fastening portions for fastening to the attachment member at both ends in the extending direction.
The strip plate has a first bent portion and a second bent portion bent in a plane parallel to a plate surface of the strip plate, and a straight portion between the first bent portion and the second bent portion,
a wire connection terminal piece capable of being connected to an external wire is protrudingly provided on a side edge of the band plate in the straight portion,
The wire connection terminal piece is
a straight line portion extending in an extension direction from the first bent portion toward the fastening portion on one end side, and a straight line portion extending in an extension direction from the second bent portion toward the fastening portion on the other end side, the straight line portion being provided in a direction parallel to the straight line portion extending in the extension direction on one side,
Bus bar.

上記（４）の構成のバスバによれば、バスバの両端の締結部の中間に、外部電線との接続が可能な電線接続端子片が突設されているので、両端の締結部の締結を解除することなく、バスバに対し外部電線を分岐接続することができる。したがって、後から電源回路の分岐の必要が生じた場合にも、単にバスバに設けた電線接続端子片に外部電線を接続するだけで簡単に実現できる。また、バスバが複数の屈曲部を有しているので、屈曲部が形成される位置を調整することにより、締結対象のバリエーションに応じたバスバの配索を実現できると共に、両屈曲部間の直線部に設けられた電線接続端子部の位置の調節も容易になる。 According to the bus bar of the above configuration (4), a wire connection terminal piece that can be connected to an external electric wire is protruded from the middle of the fastening parts at both ends of the bus bar, so that an external electric wire can be branched and connected to the bus bar without releasing the fastening parts at both ends. Therefore, even if it becomes necessary to branch the power supply circuit later, this can be easily achieved by simply connecting the external electric wire to the wire connection terminal piece provided on the bus bar. In addition, since the bus bar has multiple bends, by adjusting the positions at which the bends are formed, it is possible to realize the wiring of the bus bar according to the variation of the fastening object, and it is also easy to adjust the position of the wire connection terminal part provided on the straight part between the two bends.

本発明によれば、既に両端の締結部が締結対象部材に締結されているバスバに対しても、締結を解除しないで、後から容易に外部電線を分岐接続することができ、後付けで電源回路の増設が容易にできる。 According to the present invention, even for bus bars whose fastening portions at both ends are already fastened to the fastening target members, external electric wires can be easily branched and connected later without releasing the fastening, making it easy to add power circuits later.

図１に示すように、本実施形態に係る電源回路部材１は、延在方向の両端に取付対象部材に対する締結部１１、１２を有する良導電性金属のバスバ１０と、バスバ１０の延在形状に沿って形成されてバスバ１０を収容する樹脂製のハウジング３０と、を備えている。ハウジング３０は、バスバ１０を構成する帯板の厚み方向に半割りされて合体されたアッパカバー３０Ａとロアカバー３０Ｂとによって構成されている。 As shown in FIG. 1, the power supply circuit component 1 according to this embodiment includes a bus bar 10 made of a highly conductive metal having fastening portions 11, 12 at both ends in the extension direction for fastening to a target component, and a resin housing 30 formed along the extension shape of the bus bar 10 to accommodate the bus bar 10. The housing 30 is composed of an upper cover 30A and a lower cover 30B that are joined together after being split in half in the thickness direction of the strip that constitutes the bus bar 10.

バスバ１０は、帯板状に形成されており、帯板の板面に平行な面内で屈曲された第１の屈曲部１３および第２の屈曲部１４ならびに両屈曲部１３、１４の間の直線部１６を有している。第１の屈曲部１３および第２の屈曲部１４は、両屈曲部１３、１４間に位置する直線部１６から見て反対方向に直角に屈曲している。 The busbar 10 is formed in a strip shape, and has a first bent portion 13 and a second bent portion 14 that are bent in a plane parallel to the strip surface, and a straight portion 16 between the two bent portions 13, 14. The first bent portion 13 and the second bent portion 14 are bent at right angles in the opposite direction as viewed from the straight portion 16 located between the two bent portions 13, 14.

各屈曲部１３、１４から両端の締結部１１、１２へ向けて延在する部分は、互いに平行な直線部１５、１７として構成されている。また、これら両端の締結部１１、１２へ向けて延在する直線部１５、１７の締結部１１、１２寄りの位置には、両端の締結部１１、１２を互いに反対の外向きに向ける直角屈曲部１８、１９が設けられている。なお、両端の締結部１１、１２は、ネジ止めのための取付孔１１ａ、１２ａが形成された端子部として構成されている。 The portions extending from the bent portions 13, 14 toward the fastening portions 11, 12 at both ends are configured as straight line portions 15, 17 that are parallel to each other. In addition, the straight line portions 15, 17 extending toward the fastening portions 11, 12 at both ends have right-angle bent portions 18, 19 at positions close to the fastening portions 11, 12, which direct the fastening portions 11, 12 at both ends in opposite outward directions. The fastening portions 11, 12 at both ends are configured as terminal portions in which mounting holes 11a, 12a for screw fastening are formed.

また、バスバ１０は、第１の屈曲部１３および第２の屈曲部１４間の直線部１６の側縁部に、外部電線Ｗ１、Ｗ２とのコネクタ接続が可能な２つの電線接続端子片（電線接続端子部）２１、２２を有している。電線接続端子片２１、２２は、両者の間に適当な間隔を開けて側縁部から突設されている。 The busbar 10 also has two wire connection terminal pieces (wire connection terminal parts) 21, 22 that can be connected to external wires W1, W2 at the side edges of the straight section 16 between the first bend 13 and the second bend 14. The wire connection terminal pieces 21, 22 protrude from the side edges with an appropriate gap between them.

電線接続端子片２１、２２は、第１の屈曲部１３および第２の屈曲部１４間の直線部１６の延在方向に対して垂直方向に突設されている。つまり、電線接続端子片２１、２２は、第１の屈曲部１３から一方の端部の締結部１１へ向けて延在する直線部１５と平行な方向へ向けて突設されている。 The electric wire connection terminal pieces 21, 22 are provided so as to protrude perpendicularly to the extending direction of the straight portion 16 between the first bent portion 13 and the second bent portion 14. In other words, the electric wire connection terminal pieces 21, 22 are provided so as to protrude in a direction parallel to the straight portion 15 extending from the first bent portion 13 toward the fastening portion 11 at one end.

したがって、図３に示すように、これらの電線接続端子片２１、２２に対して、外部電線Ｗ１、Ｗ２のコネクタＣ１、Ｃ２の端子１０１、１０２が、第１の屈曲部１３および第２の屈曲部１４間の直線部１６の延在方向に垂直な方向（図１（ａ）および図３中の矢印Ｓ方向）に着脱自在とされている。 Therefore, as shown in FIG. 3, the terminals 101, 102 of the connectors C1, C2 of the external wires W1, W2 can be freely attached and detached to these wire connection terminal pieces 21, 22 in a direction perpendicular to the extension direction of the straight portion 16 between the first bend 13 and the second bend 14 (the direction of the arrow S in FIG. 1(a) and FIG. 3).

ハウジング３０は、図１（ａ）に示すように、バスバ１０の各部を、バスバ１０の延在形状に沿って収容するように形成されている。すなわち、ハウジング３０には、バスバ１０の第１の屈曲部１３、第２の屈曲部１４、直線部１６、１５、１７、直角屈曲部１８、１９をそれぞれ収容する部分として、第１、第２の屈曲部３３、３４、直線部３５、３６、３７、直角屈曲部３８、３９が設けられている。また、バスバ１０の両端の締結部１１、１２を引き出すための部分３１、３２が設けられている。 As shown in FIG. 1(a), the housing 30 is formed to accommodate each portion of the busbar 10 along the extending shape of the busbar 10.

In addition, portions 31 and 32 are provided for drawing out the fastening portions 11 and 12 at both ends of the busbar 10.

このような形状のハウジング３０を構成するために、図１（ｂ）に示すように、アッパカバー３０Ａには、これらの部分３１、３２、３３、３４、３５、３６、３７、３８、３９を構成するための部分３１Ａ、３２Ａ、３３Ａ、３４Ａ、３５Ａ、３６Ａ、３７Ａ、３８Ａ、３９Ａが設けられ、ロアカバー３０Ｂには、３１Ｂ、３２Ｂ、３３Ｂ、３４Ｂ、３５Ｂ、３６Ｂ、３７Ｂ、３８Ｂ、３９Ｂが設けられている。 To form the housing 30 in this shape, as shown in FIG. 1(b), the upper cover 30A is provided with parts 31A, 32A, 33A, 34A, 35A, 36A, 37A, 38A, and 39A for forming these parts 31, 32, 33, 34, 35, 36, 37, 38, and 39, and the lower cover 30B is provided with parts 31B, 32B, 33B, 34B, 35B, 36B, 37B, 38B, and 39B.

また、アッパカバー３０Ａとロアカバー３０Ｂには、両者の間にバスバ１０を収容し合体してハウジング３０を構成する際に、互いをロックするための係合部４１Ａ、４１Ｂが設けられている。 In addition, the upper cover 30A and the lower cover 30B are provided with engagement portions 41A and 41B for locking them together when the bus bar 10 is housed between them and they are combined to form the housing 30.

また、ハウジング３０には、バスバ１０の電線接続端子片２１、２２を収容して外部電線Ｗ１、Ｗ２のコネクタＣ１、Ｃ２と嵌合可能なコネクタ２６、２７を形成するコネクタハウジング部５１、５２が設けられている。コネクタハウジング部５１を構成するために、アッパカバー３０Ａとロアカバー３０Ｂには、両者の間に電線接続端子片２１を収容するコネクタハウジング構成部５１Ａ、５１Ｂが設けられている。また、コネクタハウジング部５２を構成するために、アッパカバー３０Ａとロアカバー３０Ｂには、両者の間に電線接続端子片２２を収容するコネクタハウジング構成部５２Ａ、５２Ｂが設けられている。 The housing 30 is also provided with connector housing portions 51, 52 that accommodate the electric wire connection terminal pieces 21, 22 of the busbar 10 to form connectors 26, 27 that can be mated with the connectors C1, C2 of the external electric wires W1, W2. To form the connector housing portion 51, the upper cover 30A and the lower cover 30B are provided with connector housing components 51A, 51B that accommodate the electric wire connection terminal piece 21 between them. To form the connector housing portion 52, the upper cover 30A and the lower cover 30B are provided with connector housing components 52A, 52B that accommodate the electric wire connection terminal piece 22 between them.

そして、ハウジング３０内にバスバ１０を収容して完成させた電源回路部材１には、図１（ａ）に示すように、バスバ１０の屈曲部１３、１４、直線部１５、１６、１７、直角屈曲部１８，１９にそれぞれ対応した部分３、４、５、６、７、８、９が設けられている。 The power supply circuit component 1, which is completed by housing the bus bar 10 in the housing 30, has sections 3, 4, 5, 6, 7, 8, and 9 that correspond to the bent sections 13, 14, the straight sections 15, 16, and 17, and the right-angle bent sections 18 and 19 of the bus bar 10, as shown in FIG. 1(a).

以上の構成の電源回路部材１によれば、バスバ１０の両端の締結部１１、１２の中間に、外部電線Ｗ１、Ｗ２とのコネクタ接続が可能な電線接続端子片（電線接続端子部）２１、２２が設けられているので、両端の締結部１１、１２の締結を解除することなく、バスバ１０に対し外部電線Ｗ１、Ｗ２を分岐接続することができる。したがって、後から電源回路の分岐の必要が生じた場合にも、単にバスバ１０に設けた電線接続端子片２１、２２に外部電線Ｗ、Ｗ２をコネクタ接続するだけで簡単に実現できる。また、バスバ１０が複数の屈曲部１３、１４を有しているので、屈曲部１３、１４が形成される位置を調整することにより、締結対象のバリエーションに応じたバスバ１０の配索を実現できると共に、両屈曲部１３、１４間の直線部１６に設けられた電線接続端子片２１、２２の位置の調節も容易になる。 According to the power supply circuit member 1 having the above configuration, the wire connection terminal pieces (wire connection terminal parts) 21, 22 capable of connector connection with the external wires W1, W2 are provided between the fastening parts 11, 12 at both ends of the bus bar 10, so that the external wires W1, W2 can be branched and connected to the bus bar 10 without releasing the fastening parts 11, 12 at both ends. Therefore, even if the need for branching of the power supply circuit arises later, it can be easily realized by simply connecting the external wires W, W2 to the wire connection terminal pieces 21, 22 provided on the bus bar 10 by connector connection. In addition, since the bus bar 10 has multiple bends 13, 14, by adjusting the positions at which the bends 13, 14 are formed, the bus bar 10 can be arranged in accordance with the variation of the fastening object, and the positions of the wire connection terminal pieces 21, 22 provided on the straight part 16 between the bends 13, 14 can also be easily adjusted.

また、上記構成の電源回路部材１では、バスバ１０に設けた電線接続端子片２１、２２をコネクタハウジング部５１、５２で収容することで、外部電線Ｗ１、Ｗ２のコネクタＣ１、Ｃ２と接続するためのコネクタ２６、２７を形成している。そのため、外部電線Ｗ１、Ｗ２の接続および接続解除を安全かつ容易に行うことができ、不使用時には、電線接続端子片２１、２２を外部に露出しないように保護することができて安全性を確保することができる。 In addition, in the power supply circuit member 1 configured as described above, the electric wire connection terminal pieces 21, 22 provided on the bus bar 10 are housed in the connector housing parts 51, 52 to form connectors 26, 27 for connecting to the connectors C1, C2 of the external electric wires W1, W2. Therefore, the external electric wires W1, W2 can be safely and easily connected and disconnected, and when not in use, the electric wire connection terminal pieces 21, 22 can be protected from exposure to the outside, ensuring safety.

また、上記構成の電源回路部材１によれば、図２、図３に示すように、バスバ１０の電線接続端子片２１、２２にコネクタ接続した外部電線Ｗ１、Ｗ２の延びる方向を、両屈曲部１３、１４間の直線部１６と垂直な方向に設定できるので、バスバ１０つまり電源回路部材１と外部電線Ｗ１、Ｗ２との相互干渉をできるだけ抑制することができる。 In addition, with the power supply circuit member 1 having the above configuration, as shown in Figures 2 and 3, the direction in which the external electric wires W1, W2 connected to the electric wire connection terminal pieces 21, 22 of the bus bar 10 extend can be set perpendicular to the straight portion 16 between the two bent portions 13, 14, so that mutual interference between the bus bar 10, i.e., the power supply circuit member 1, and the external electric wires W1, W2 can be suppressed as much as possible.

また、バスバ１０の電線接続端子片２１、２２にコネクタ接続した外部電線Ｗ１、Ｗ２を、第１の屈曲部１３から一方の締結部１１に延びるバスバ１０の延在方向と平行な方向に引き延ばすことができる。そのため、バスバ１０つまり電源回路部材１と外部電線Ｗ１、Ｗ２の配索領域をコンパクトに収めることができる。また、図１（ａ）に示すように、外部電線Ｗ１、Ｗ２が接続されていない状態でも、電線接続端子片２１、２２が、バスバ１０の両屈曲部１３、１４間の直線部１６から、バスバ１０の端部（締結部１１）と屈曲部（第１の屈曲部１３）との間におけるバスバ１０の延在方向に沿った方向に突出しているので、屈曲部（第１の屈曲部１３）から端部（締結部１１）に向けて延びるバスバ１０の部分（直線部１５）を「袖」と見立てると、電線接続端子片２１、２２が袖の内側に隠れて存在するような形になり、バスバを配索する際の邪魔になりにくい。 In addition, the external electric wires W1, W2 connected by connectors to the electric wire connection terminal pieces 21, 22 of the bus bar 10 can be extended in a direction parallel to the extension direction of the bus bar 10 extending from the first bend 13 to one of the fastening portions 11. This allows the bus bar 10, i.e., the power supply circuit member 1 and the wiring area for the external electric wires W1, W2 to be compactly stored. Also, as shown in FIG. 1(a), even when the external electric wires W1, W2 are not connected, the electric wire connection terminal pieces 21, 22 protrude from the straight portion 16 between the two bent portions 13, 14 of the bus bar 10 in a direction along the extension direction of the bus bar 10 between the end portion (fastening portion 11) and the bent portion (first bent portion 13) of the bus bar 10. If the portion (straight portion 15) of the bus bar 10 extending from the bent portion (first bent portion 13) toward the end portion (fastening portion 11) is considered as a "sleeve," the electric wire connection terminal pieces 21, 22 are hidden inside the sleeve and are unlikely to get in the way when wiring the bus bar.
