（４） 複数の電池で構成された電池集合体と、前記電池集合体に重ねて取り付けられるとともに前記各電池を互いに電気的に接続するバスバモジュールと、を備える電源装置において、
前記バスバモジュールとして、上記（１）〜（３）のいずれか１項に記載のバスバモジュールを有していること。 In order to achieve the above-described object, the bus bar module and the power supply device according to the present invention are characterized by the following points.
(1) A plurality of bus bars that electrically connect each battery of a battery assembly composed of a plurality of batteries, a plurality of electric wires that are electrically connected to the respective batteries via the plurality of bus bars, A bus bar module comprising: a wire arrangement that accommodates the plurality of wires;
The wire arrangement is
An electric wire routing groove portion that is formed in a bowl shape that opens upward, and accommodates the electric wire;
A lid portion that is rotatably connected to one side wall of the wire routing groove portion via a hinge and covers the wire routing groove portion so as to close a groove opening of the wire routing groove portion,
An electric wire holding portion projecting from the one side wall toward the other side wall;
When the electric wire is positioned above the electric wire holding portion when the cover portion is protruded on the hinge side and the cover portion rotates and covers the electric wire routing groove portion, A rib for extruding the electric wire from above the electric wire holding portion;
Having
(2) A bus bar module configured as described in (1) above,
The wire holding portion and the rib are formed at different positions in the longitudinal direction of the wire routing groove portion,
At a position corresponding to the rib on the one side wall, a notch is formed through which a part of the rib passes when the lid portion rotates and covers the wire routing groove portion.
about.
(3) A bus bar module configured as one of the above (1) and (2),
The rib has an inclined surface inclined so as to be separated from the lid portion toward the hinge side,
When the lid is rotated and covered with the wire routing groove, the inclined surface comes into contact with the electric wire and pushes out the electric wire from the upper part of the electric wire holding portion.
about.
(4) In a power supply device comprising: a battery assembly composed of a plurality of batteries; and a bus bar module that is attached to the battery assembly and is electrically connected to each other.
The bus bar module according to any one of (1) to (3) above is provided as the bus bar module.

上記（１）の構成のバスバモジュールにおける電線配索体のように電線抑え部を備える場合には、電線配索溝部に電線を収容すると、電線抑え部によって電線の浮き上がりが抑制される。これにより、電線配索溝部へ電線を円滑に収容することができる。そして、この電線配索溝部に電線を収容した状態で蓋部を回動させ、電線配索溝部の溝開口を塞ぐことで、電線配索溝部に収容された電線の保護を図るとともに電線配索溝部からの電線の飛び出しを防止することができる。
ところで、電線抑え部を設けた電線配索体では、電線配索溝部に電線を収容する際に、電線が電線配索溝部内へ入らず、電線抑え部に電線が引っ掛かり、電線抑え部の上方に電線が配置された状態となる場合がある。この電線抑え部の上方に配置された電線は、電線抑え部の上部に接触していたり、電線自体の張力によって電線抑え部の上部から僅かに浮き上がった状態となっている。
このような状態で、電線配索溝部の溝開口を塞ぐべく、蓋部を回動させると、電線抑え部と蓋部との間に電線を挟み込んでしまう虞がある。このような場合、蓋部を閉じる作業を一旦中断させ、蓋部を逆方向へ回動させて溝開口を開き、電線抑え部の上方に配置された電線を改めて電線配索溝部内へ収容させ、蓋部を再度回動させて電線配索溝部の溝開口を塞がなければならず、電線の配索時における作業性が低下してしまう。
これに対して、上記（１）の構成のバスバモジュールにおける電線配索体では、電線抑え部に電線が引っ掛かり、電線抑え部の上方に電線が配置された状態で、電線配索溝部の溝開口を塞ぐべく、蓋部を回動させると、蓋部のヒンジ側に突設するリブが電線に接触する。この状態で蓋部を更に回動させると、電線がリブによって一方の側壁側から他方の側壁側へ向かって押し出される。これにより、電線は、電線抑え部上を他方の側壁側へ向かってスライド移動し、電線抑え部の上方から押し出されて電線抑え部と他方の側壁との間から電線配索溝部内へ入れられる。そして、蓋部を更に回動させることで、蓋部によって電線配索溝部の溝開口が塞がれる。
このため、上記（１）の構成のバスバモジュールによれば、電線配索溝部の溝開口を塞ぐべく、蓋部を回動させる際の電線抑え部と蓋部との間への電線の挟み込みを確実に防止することができる。したがって、電線抑え部と蓋部との間への電線の挟み込みによる電線の配索作業の中断などをなくし、円滑に配索作業を行うことができる。
このように、上記（１）の構成のバスバモジュールによれば、電線の配索時における作業性が向上されたバスバモジュールを提供できる。
上記（２）の構成のバスバモジュールにおける電線配索体では、電線抑え部とリブとが、電線配索溝部の長手方向において異なる位置に形成されており、一方の側壁におけるリブに対応する位置に、蓋部が回動して電線配索溝部に被せられる際にリブの一部が通過する切欠きが形成されている。これにより、蓋部を回動させて電線配索溝部の溝開口を覆うように塞ぐ際に、リブが一方の側壁に干渉するようなことがなく、また、電線配索溝部内に収容されている電線がリブと一方の側壁との間で挟まれるような不具合も抑制することができる。このため、上記（２）の構成のバスバモジュールによれば、電線の配索の作業性の円滑化を図ることができる。
上記（３）の構成のバスバモジュールにおける電線配索体では、リブが、ヒンジ側に向けて蓋部から離間するように傾斜した傾斜面を有しているので、蓋部が回動して電線配索溝部に被せられる際に、傾斜面が電線に接触して電線を電線抑え部の上部から徐々に押し出すこととなる。これにより、電線抑え部の上部から電線を極めて円滑に押し出すことができる。このため、上記（３）の構成のバスバモジュールによれば、電線の配索の作業性の更なる円滑化を図ることができる。
上記（４）の構成の電源装置によれば、上述した理由と同様の理由により、電線の配索時における作業性が向上した電源装置を提供できる。 In the case where the wire restraining portion is provided like the wire routing body in the bus bar module having the configuration of (1) above, when the wire is accommodated in the wire routing groove portion, the wire restraining portion suppresses the lifting of the wire. Thereby, an electric wire can be smoothly accommodated in an electric wire routing groove part. Then, the lid portion is rotated in a state where the electric wire is accommodated in the electric wire arrangement groove portion, and the groove opening of the electric wire arrangement groove portion is closed, thereby protecting the electric wire accommodated in the electric wire arrangement groove portion and the electric wire arrangement. It is possible to prevent the electric wire from jumping out of the groove.
By the way, in the electric wire arrangement body provided with the electric wire holding portion, when the electric wire is accommodated in the electric wire arrangement groove portion, the electric wire does not enter the electric wire arrangement groove portion, and the electric wire is caught in the electric wire holding portion, and above the electric wire holding portion. There is a case where the electric wire is arranged in the state. The electric wire arranged above the electric wire holding portion is in contact with the upper portion of the electric wire holding portion or slightly lifted from the upper portion of the electric wire holding portion due to the tension of the electric wire itself.
In such a state, if the lid portion is rotated so as to close the groove opening of the electric wire routing groove portion, the electric wire may be sandwiched between the electric wire holding portion and the lid portion. In such a case, the operation of closing the lid is temporarily interrupted, the lid is rotated in the reverse direction to open the groove opening, and the electric wire arranged above the electric wire holding portion is accommodated again in the electric wire routing groove. Then, the lid portion must be rotated again to close the groove opening of the electric wire routing groove portion, and workability during wiring of the electric wire is reduced.
On the other hand, in the electric wire arrangement body in the bus bar module having the configuration (1), the electric wire is hooked on the electric wire holding portion, and the electric wire is arranged above the electric wire holding portion. When the lid is turned to close the cover, the rib protruding from the hinge side of the lid contacts the electric wire. When the lid portion is further rotated in this state, the electric wire is pushed out from one side wall side to the other side wall side by the rib. As a result, the electric wire slides on the electric wire holding portion toward the other side wall, is pushed out from above the electric wire holding portion, and is inserted into the electric wire routing groove from between the electric wire holding portion and the other side wall. . And the groove opening of an electric wire wiring groove part is block | closed by a cover part by further rotating a cover part.
For this reason, according to the bus bar module having the configuration of (1), the electric wire is sandwiched between the electric wire holding portion and the lid portion when the lid portion is rotated so as to close the groove opening of the electric wire routing groove portion. It can be surely prevented. Therefore, it is possible to eliminate the interruption of the wiring operation due to the insertion of the electric wire between the electric wire holding portion and the lid portion, and to perform the wiring operation smoothly.
As described above, according to the bus bar module having the configuration (1), it is possible to provide a bus bar module with improved workability at the time of wiring.
In the wire routing body in the bus bar module configured as described above (2), the wire holding portion and the rib are formed at different positions in the longitudinal direction of the wire routing groove portion, and at a position corresponding to the rib on one side wall. A notch through which a part of the rib passes is formed when the lid portion is rotated and covered with the electric wire routing groove portion. This prevents the rib from interfering with one of the side walls when the lid is rotated so as to cover the groove opening of the electric cable routing groove, and is also accommodated in the electric cable routing groove. It is also possible to suppress a problem such that the existing electric wire is sandwiched between the rib and one side wall. For this reason, according to the bus bar module of the structure of said (2), smoothness of the workability | work of wiring of an electric wire can be aimed at.
In the wire arrangement body in the bus bar module having the configuration of (3) above, the rib has an inclined surface that is inclined so as to be separated from the lid portion toward the hinge side. When covering the wiring groove portion, the inclined surface comes into contact with the electric wire, and the electric wire is gradually pushed out from the upper portion of the electric wire holding portion. Thereby, an electric wire can be extruded very smoothly from the upper part of an electric wire control part. For this reason, according to the bus bar module having the configuration (3), it is possible to further facilitate the workability of the wiring of the electric wires.
According to the power supply device having the configuration (4), it is possible to provide a power supply device with improved workability at the time of wiring, for the same reason as described above.

本発明によれば、電線の配索時における作業性を向上可能なバスバモジュール及び電源装置を提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the bus bar module and power supply device which can improve workability | operativity at the time of wiring of an electric wire can be provided.

上記構成の電線配索体６において、電線配索溝部６４に電線５を収容すると、電線５は、電線抑え部９１によって浮き上がりが抑えられる。これにより、電線配索溝部６４への電線５の収容作業を円滑に行うことができる。そして、この電線配索溝部６４に電線５を収容した状態で蓋部６７を、電線配索溝部６４に被せる方向（図５中矢印Ａ方向）へ回動させ、電線配索溝部６４の溝開口６４Ａを塞ぐことで、電線配索溝部６４に収容された電線５の保護を図ることができるとともに電線配索溝部６４からの電線５の飛び出しを防止することができる。   When the electric wire 5 is accommodated in the electric wire routing groove portion 64 in the electric wire routing body 6 having the above-described configuration, the electric wire 5 is suppressed from being lifted by the electric wire holding portion 91. Thereby, the accommodation operation | work of the electric wire 5 to the electric wire routing groove part 64 can be performed smoothly. Then, the lid 67 is rotated in a direction (in the direction of arrow A in FIG. 5) in the state where the electric wire 5 is accommodated in the electric wire routing groove 64 to open the groove opening of the electric wire routing groove 64. By blocking 64A, it is possible to protect the electric wire 5 accommodated in the electric wire routing groove 64 and to prevent the electric wire 5 from jumping out from the electric wire routing groove 64.

以下では、実施形態に係るバスバモジュール１及び電源装置１０の作用及び効果について説明する。   Below, the effect | action and effect of the bus bar module 1 and the power supply device 10 which concern on embodiment are demonstrated.

まず、図６を参照して、比較例として示すバスバモジュール１Ａの電線配索体６Ａについて説明する。図６は、比較例として示すバスバモジュールの電線配索体を示す図であり、図６（ａ）は蓋部を開いた状態を、図６（ｂ）は蓋部を閉じる途中の状態を示している。   First, with reference to FIG. 6, the electric wire arrangement | positioning body 6A of the bus bar module 1A shown as a comparative example is demonstrated. 6A and 6B are diagrams showing a wire arrangement of a bus bar module shown as a comparative example. FIG. 6A shows a state in which the lid is opened, and FIG. 6B shows a state in the middle of closing the lid. ing.

図６（ａ）及び図６（ｂ）に示す比較例に係るバスバモジュール１Ａの電線配索体６Ａは、リブ９５、切欠き９７等が形成されていない点以外は上記実施形態に係るバスバモジュール１の電線配索体６と同一の構成を有するので、同一の部材については同一の符号を付して説明を省略する。   6A of the bus bar module 1A according to the comparative example shown in FIG. 6A and FIG. 6B is the bus bar module according to the above embodiment except that the rib 95, the notch 97 and the like are not formed. Since it has the same configuration as that of the one electric wire routing body 6, the same members are denoted by the same reference numerals and description thereof is omitted.

図６（ａ）に示すように、比較例に係る電線配索体６Ａでは、リブ９５、切欠き９７等を備えていない。この電線配索体６Ａにおいても、電線配索溝部６４に電線５を収容すると、電線抑え部９１によって電線５の浮き上がりが抑えられる。これにより、電線配索溝部６４への電線５の収容作業が円滑に行える。そして、この電線配索溝部６４に電線５を収容した状態で蓋部６７を、電線配索溝部６４に被せる方向（図６中矢印Ａ方向）へ回動させ、電線配索溝部６４の溝開口６４Ａを塞ぐことで、電線配索溝部６４に収容された電線５の保護が図られるとともに電線配索溝部６４からの電線５の飛び出しが防止される。   As shown to Fig.6 (a), in the electric wire wiring body 6A which concerns on a comparative example, the rib 95, the notch 97 grade | etc., Is not provided. Also in this electric wire routing body 6 </ b> A, when the electric wires 5 are accommodated in the electric wire routing grooves 64, the lifting of the electric wires 5 is suppressed by the electric wire holding portion 91. Thereby, the accommodation operation | work of the electric wire 5 to the electric wire routing groove part 64 can be performed smoothly. Then, the lid 67 is rotated in a direction (in the direction of arrow A in FIG. 6) to cover the electric wire routing groove 64 in a state where the electric wire 5 is accommodated in the electric wire routing groove 64, thereby opening the groove of the electric wire routing groove 64. By blocking 64A, the electric wire 5 accommodated in the electric wire routing groove 64 is protected and the electric wire 5 is prevented from jumping out from the electric wire routing groove 64.

ところで、電線配索溝部６４に電線５を収容する際に、電線５が電線配索溝部６４内へ入らず、電線抑え部９１に電線５が引っ掛かり、電線抑え部９１の上方に電線５が配置された状態となることがある。この電線抑え部９１の上方に配置された電線５は、電線抑え部９１の上部に接触していたり、電線５自体の張力によって電線抑え部９１の上部から僅かに浮き上がった状態となる。   By the way, when the electric wire 5 is accommodated in the electric wire routing groove portion 64, the electric wire 5 does not enter the electric wire routing groove portion 64, the electric wire 5 is caught by the electric wire holding portion 91, and the electric wire 5 is arranged above the electric wire holding portion 91. It may become the state that was done. The electric wire 5 arranged above the electric wire holding portion 91 is in contact with the upper portion of the electric wire holding portion 91 or slightly lifted from the upper portion of the electric wire holding portion 91 due to the tension of the electric wire 5 itself.

このような状態で、電線配索溝部６４の溝開口６４Ａを塞ぐべく、蓋部６７を回動させると、図６（ｂ）に示すように、電線抑え部９１と蓋部６７との間に電線５を挟み込んでしまうことがある。このような場合、蓋部６７を閉じる作業を一旦中断させ、蓋部６７を逆方向へ回動させて溝開口６４Ａを開き、電線抑え部９１の上方に配置された電線５を改めて電線配索溝部６４内へ収容させ、蓋部６７を再度矢印Ａ方向へ回動させて電線配索溝部６４の溝開口６４Ａを塞がなければならず、電線５の配索時における作業性が低下してしまう。   In such a state, when the lid portion 67 is rotated so as to close the groove opening 64A of the wire routing groove portion 64, as shown in FIG. 6B, between the wire holding portion 91 and the lid portion 67, as shown in FIG. The electric wire 5 may be pinched. In such a case, the operation of closing the lid portion 67 is temporarily interrupted, the lid portion 67 is rotated in the reverse direction to open the groove opening 64A, and the electric wire 5 disposed above the electric wire holding portion 91 is re-wired. The groove opening 64A is accommodated in the groove portion 64 and the lid portion 67 is rotated again in the direction of the arrow A to close the groove opening 64A of the wire wiring groove portion 64. End up.

図７は、実施形態に係る電線配索体の一部の、蓋部を閉じる途中の状態における斜視図である。図８は、図７に示す電線配索体の一部の断面図である。   FIG. 7 is a perspective view of a part of the electric wire arrangement according to the embodiment in a state in the middle of closing the lid. FIG. 8 is a cross-sectional view of a part of the electric wire arrangement shown in FIG.

上記のような比較例に対して、実施形態に係るバスバモジュール１の電線配索体６では、図７及び図８に示すように、電線抑え部９１に電線５が引っ掛かり、電線抑え部９１の上方に電線５が配置された状態で、電線配索溝部６４の溝開口６４Ａを塞ぐべく、蓋部６７を、電線配索溝部６４に被せる方向（図５中矢印Ａ方向）へ回動させると、蓋部６７のヒンジ６７Ａ側に突設するリブ９５が電線５に接触する。この状態で蓋部６７を更に回動させると、電線５がリブ９５によって、一方の側壁６６Ａ側から他方の側壁６６Ｂ側へ向かって押し出される。これにより、電線５は、電線抑え部９１上を他方の側壁６６Ｂ側へ向かってスライドし、電線抑え部９１の上方から押し出されて電線抑え部９１と他方の側壁６６Ｂとの間から電線配索溝部６４内へ向かって（図８中矢印Ｂ方向）へ移動され、電線配索溝部６４内へ入れられる。そして、蓋部６７を更に回動させることで、蓋部６７によって電線配索溝部６４の溝開口６４Ａが塞がれる。   In contrast to the comparative example as described above, in the electric wire routing body 6 of the bus bar module 1 according to the embodiment, as shown in FIGS. 7 and 8, the electric wire 5 is caught on the electric wire holding portion 91, and the electric wire holding portion 91 When the lid 67 is rotated in a direction (arrow A direction in FIG. 5) to cover the wire routing groove 64 in order to close the groove opening 64A of the wire routing groove 64 with the electric wire 5 disposed above. The rib 95 protruding from the lid 67 on the hinge 67 </ b> A side contacts the electric wire 5. When the lid 67 is further rotated in this state, the electric wire 5 is pushed out by the rib 95 from the one side wall 66A side toward the other side wall 66B side. Thereby, the electric wire 5 slides on the electric wire holding | suppressing part 91 toward the other side wall 66B side, and is pushed out from the upper direction of the electric wire holding | suppressing part 91, and electric wire routing is carried out from between the electric wire holding | suppressing part 91 and the other side wall 66B. It moves toward the inside of the groove part 64 (in the direction of arrow B in FIG. 8) and is put into the electric wire routing groove part 64. Then, by further rotating the lid portion 67, the groove opening 64 </ b> A of the wire routing groove portion 64 is closed by the lid portion 67.

このため、実施形態に係るバスバモジュール１の電線配索体６では、電線配索溝部６４の溝開口６４Ａを塞ぐべく、蓋部６７を回動させる際の電線抑え部９１と蓋部６７との間への電線５の挟み込みを確実に防止することができる。したがって、電線抑え部９１と蓋部６７との間への電線５の挟み込みによる電線５の配索作業の中断などをなくし、円滑に配索作業を行うことができる。   For this reason, in the electric wire routing body 6 of the bus bar module 1 according to the embodiment, the electric wire holding portion 91 and the lid portion 67 when the lid portion 67 is rotated to close the groove opening 64A of the electric wire routing groove portion 64. It is possible to reliably prevent the electric wire 5 from being sandwiched therebetween. Therefore, it is possible to eliminate the interruption of the wiring operation of the electric wire 5 due to the pinching of the electric wire 5 between the electric wire holding portion 91 and the lid portion 67 and perform the wiring operation smoothly.

このため、実施形態に係るバスバモジュール１によれば、電線５の配索時における作業性が向上されたバスバモジュールを提供できる。また、実施形態に係る電源装置１０によれば、上述した理由と同様の理由により、電線の配索時における作業性が向上された電源装置を提供できる。   For this reason, according to the bus bar module 1 which concerns on embodiment, the bus bar module by which the workability | operativity at the time of wiring of the electric wire 5 was improved can be provided. Moreover, according to the power supply device 10 which concerns on embodiment, the power supply device by which the workability | operativity at the time of wiring of an electric wire was improved can be provided for the reason similar to the reason mentioned above.

また、実施形態に係るバスバモジュール１の電線配索体６では、電線抑え部９１とリブ９５とが、電線配索溝部６４の長手方向において異なる位置に形成されており、一方の側壁６６Ａにおけるリブ９５に対応する位置に、蓋部６７が回動して電線配索溝部６４に被せられる際にリブ９５の一部が通過する切欠き９７が形成されている。これにより、蓋部６７を回動させて電線配索溝部６４の溝開口６４Ａを覆うように塞ぐ際に、リブ９５が一方の側壁６６Ａに干渉するようなことがなく、また、電線配索溝部６４内に収容されている電線５がリブ９５と一方の側壁６６Ａとの間で挟まれるような不具合も抑制することができる。この結果、電線５の配索の作業性の円滑化を図ることができる。   Moreover, in the electric wire routing body 6 of the bus bar module 1 according to the embodiment, the electric wire holding portion 91 and the rib 95 are formed at different positions in the longitudinal direction of the electric wire routing groove portion 64, and the rib on one side wall 66A. A notch 97 through which a part of the rib 95 passes is formed at a position corresponding to 95 when the lid portion 67 rotates and covers the wire routing groove portion 64. Thus, when the lid portion 67 is rotated so as to cover the groove opening 64A of the wire routing groove portion 64, the rib 95 does not interfere with the one side wall 66A, and the wire routing groove portion The malfunction that the electric wire 5 accommodated in 64 is pinched | interposed between the rib 95 and one side wall 66A can also be suppressed. As a result, the workability of the wiring of the electric wire 5 can be facilitated.

また、上記実施形態に係るバスバモジュール１の電線配索体６では、リブ９５が、ヒンジ６７Ａ側に向けて蓋部６７から離間するように傾斜した傾斜面９５Ａを有しているので、蓋部６７が回動して電線配索溝部６４に被せられる際に、傾斜面９５Ａが電線５に接触して電線５を電線抑え部９１の上部から徐々に押し出すこととなる。これにより、電線抑え部９１の上部から電線５を極めて円滑に押し出すことができる。このため、上記実施形態に係るバスバモジュール１によれば、電線５の配索の作業性の更なる円滑化を図ることができる。   Moreover, in the electric wire routing body 6 of the bus bar module 1 according to the above-described embodiment, the rib 95 has the inclined surface 95A inclined so as to be separated from the lid portion 67 toward the hinge 67A side. When 67 is rotated and covered with the wire routing groove portion 64, the inclined surface 95 </ b> A comes into contact with the wire 5 and gradually pushes the wire 5 from the upper portion of the wire holding portion 91. Thereby, the electric wire 5 can be extruded very smoothly from the upper part of the electric wire holding | suppressing part 91. FIG. For this reason, according to the bus bar module 1 which concerns on the said embodiment, the further smoothness of the workability | operativity of the wiring of the electric wire 5 can be aimed at.
