　そして、この高電圧用の二次電池には、複数の板状電池の端子電圧を検知することで充電状態を監視できるように、それぞれ対応するバスバーに接触する複数の検知端子付きの検知電線群を樹脂製の保護カバーに収納した電池配線モジュールが装着されている。 And, in this secondary battery for high voltage, a group of detection wires with a plurality of detection terminals that are in contact with the corresponding bus bars so that the state of charge can be monitored by detecting the terminal voltages of the plurality of plate batteries Is mounted in a protective cover made of resin.
　この種の電池配線モジュールとしては、例えば複数のバスバー保持部と、複数の検知電線を収納する電線収納溝部と、バスバー保持部から電線収納溝部内に検知電線を導入するための複数の切欠部と、電線収納溝部の両側壁の上部に斜下方に向けて突設された複数の対の電線押え片とを有する樹脂製のカバーを備えたものが知られている（例えば、特許文献１参照）。 As this type of battery wiring module, for example, a plurality of bus bar holding portions, a wire storage groove portion for storing a plurality of detection wires, and a plurality of cutout portions for introducing detection wires from the bus bar holding portion into the wire storage groove portion, In addition, there is known a resin cover having a plurality of pairs of electric wire pressing pieces projecting obliquely downward on the upper side walls of the electric wire storage groove (see, for example, Patent Document 1). .

　しかしながら、電線収納溝部の両側壁から溝内に突出する電線押え片を設けた従来の前者の電池配線モジュールにあっては、検知電線（以下、単に電線ともいう）のはみ出しを確実に規制すべく電線押え片の設置数を増やすと、電線収納溝部内に電線を収納する作業の作業性が悪くなるという問題があった。 However, in the former former battery wiring module provided with the electric wire pressing pieces protruding into the groove from both side walls of the electric wire housing groove portion, the protruding of the detection electric wire (hereinafter also simply referred to as an electric wire) should be reliably controlled. When the number of installed wire holding pieces is increased, there is a problem that workability of storing the electric wire in the electric wire storing groove is deteriorated.
　また、蓋部の下面側に電線押え片上から電線を押し出すリブを突設した従来の後者の電池配線モジュールにあっては、電線収納溝部の側壁面に対し電線押え片が垂直に突出する構成であったため、電線収納溝部に収納する際に電線が電線押え片に引っ掛ったり電線収納溝部に入った電線の一部が電線押え片の下面から上方に外れたりし易かった。 Further, in the latter latter battery wiring module in which a rib for pushing out the electric wire from above the electric wire holding piece is provided on the lower surface side of the lid portion, the electric wire holding piece protrudes perpendicularly to the side wall surface of the electric wire housing groove. For this reason, when the electric wire is stored in the electric wire storage groove, the electric wire is easily caught by the electric wire holding piece or a part of the electric wire that has entered the electric wire holding groove is easily detached upward from the lower surface of the electric wire holding piece.
　そのため、電線が電線押え片の基端側やそこからさらに蓋部のヒンジ側へとはみ出す場合があり、その場合、電線押え片とリブおよび蓋部との間に電線を噛み込む可能性があった。そればかりか、そのような樹脂製保護カバー内での電線の噛み込みが発生しても、外部から容易に視認できないために放置されてしまい、電線にダメージを与える可能性が高くなるため、電池配線モジュールの信頼性が低下してしまうという問題があった。 For this reason, the electric wire may protrude from the proximal end side of the electric wire holding piece or from there to the hinge side of the lid portion, in which case there is a possibility that the electric wire may be caught between the electric wire holding piece and the rib and the lid portion. It was. Not only that, even if the electric wire bites inside such a protective cover made of resin, the battery cannot be easily seen from the outside and is left unattended, which increases the possibility of damage to the electric wire. There was a problem that the reliability of the wiring module was lowered.
　本発明は、このような従来の課題を解決するためになされたものであり、検知電線の一部が電線押え片の基端側や蓋部のヒンジ側にはみ出し得る位置にあったとしても、それを外部から容易に視認したり電線収納溝部側に押しこんだりすることができ、電線が噛み込んだままになることを確実に防止することができる信頼性の高い電池配線モジュールを提供することを目的とする。 The present invention has been made to solve such a conventional problem, even if a part of the detection wire is in a position where it can protrude from the proximal end side of the wire pressing piece and the hinge side of the lid portion, To provide a highly reliable battery wiring module that can be easily visually recognized from the outside or pushed into the wire housing groove and can reliably prevent the wire from being caught. With the goal.
　本発明に係る電池配線モジュールは、上記目的達成のため、複数の板状電池が積層配置されるとともに直列に接続された電池集合体に対して装着される電池配線モジュールであって、前記複数の板状電池の端子電圧をそれぞれ検出するよう前記複数の板状電池の積層方向に向けて配置された複数の検知電線と、前記複数の検知電線を収納しつつ前記電池集合体に支持される樹脂製保護カバーと、を備え、前記樹脂製保護カバーが、前記複数の検知電線を収納する電線収納溝部と、前記電線収納溝部の両側壁のうち一方の側壁にヒンジ結合し、前記電線収納溝部を閉塞する蓋部と、前記電線収納溝部の内底壁面から離れる前記一方の側壁の上部側に、前記電線収納溝部の内方に向って突出するように設けられた複数の電線押え片と、を有しており、前記蓋部に、前記電線収納溝部を閉塞するときに前記複数の電線押え片のいずれかを収容しつつ前記一方の側壁の上部側に露出させる切欠き穴が形成されていることを特徴とする。 In order to achieve the above object, the battery wiring module according to the present invention is a battery wiring module in which a plurality of plate-like batteries are stacked and attached to a battery assembly connected in series, A plurality of detection wires arranged in the stacking direction of the plurality of plate batteries to detect terminal voltages of the plate cells, and a resin that is supported by the battery assembly while containing the plurality of detection wires A protective cover made of resin, wherein the protective cover made of resin is hinge-coupled to one of the side walls of the wire storage groove and the side walls of the wire storage groove, and the wire storage groove is A lid portion to be closed, and a plurality of wire pressing pieces provided on the upper side of the one side wall away from the inner bottom wall surface of the wire storage groove portion so as to protrude inward of the wire storage groove portion. Have The lid portion is formed with a notch hole that is exposed to the upper side of the one side wall while accommodating any of the plurality of wire pressing pieces when the wire housing groove portion is closed. And
　この構成により、本発明の電池配線モジュールでは、検知電線の一部が電線押え片の基端側や蓋部のヒンジ側にはみ出し得る位置にあったとしても、それを切欠き穴を通して外部から容易に視認でき、切欠き穴を通して電線収納溝部側に押し込むこともできる。したがって、検知電線が噛み込んだままになることを確実に防止することができる電池配線モジュールとなる。 With this configuration, in the battery wiring module of the present invention, even if a part of the detection wire is at a position where it can protrude from the proximal end side of the wire holding piece or the hinge side of the lid portion, it can be easily removed from the outside through the notch hole. It can also be visually recognized and can be pushed into the wire housing groove side through the notch hole. Therefore, it becomes a battery wiring module which can prevent reliably that the detection electric wire remains stuck.
　本発明の電池配線モジュールにおいては、前記切欠き穴が、前記複数の電線押え片のいずれかに対して少なくとも前記電線収納溝部の溝長さ方向に隙間を隔てる内周縁部を有しているのがよい。 In the battery wiring module of the present invention, the cutout hole has an inner peripheral edge portion that separates a gap in at least the length direction of the wire housing groove portion with respect to any of the plurality of wire pressing pieces. Is good.
　この場合、電線収納溝部の溝長さ方向に隙間を適宜設定することで、検知電線の収納状態を容易に目視できるとともに、蓋部を閉じる際に電線押え片上に検知電線の一部がはみ出していたとしても、検知電線にダメージを与えることを確実に防止できる。 In this case, by appropriately setting the gap in the groove length direction of the electric wire storage groove, the storage state of the detection electric wire can be easily observed, and a part of the detection electric wire protrudes on the electric wire presser piece when the lid is closed. Even if this occurs, it is possible to reliably prevent damage to the detection wires.
　本発明の電池配線モジュールにおいては、前記複数の電線押え片の基端部が、前記蓋部のヒンジ結合位置より前記電線収納溝部の内底壁面から離れる上方側に位置するとともに、前記複数の電線押え片の突出端部が前記基端部より下方側に位置するように傾斜しているのがよい。 In the battery wiring module of the present invention, the base end portions of the plurality of wire pressing pieces are located on the upper side away from the inner bottom wall surface of the wire housing groove portion from the hinge coupling position of the lid portion, and It is preferable to incline so that the protruding end portion of the presser piece is located below the base end portion.
　このようにすると、電線押え片が少なくとも突出端部側で斜下方に傾斜するので、検知電線を電線収納溝部の内方に誘い込み易くなり、かつ、電線収納溝部内に入った検知電線が外方に飛び出し難くなる。また、蓋部を閉じる際に電線押え片上に検知電線が出ていたとしても、その検知電線が蓋部の閉じ方向への回動に伴って電線収納溝部内に押し出され易くなる。 In this case, since the wire holding piece is inclined obliquely downward at least on the protruding end side, it becomes easy to guide the detection wire into the inside of the wire storage groove, and the detection wire entering the wire storage groove is outward. It becomes difficult to jump out. Moreover, even if the detection electric wire has come out on the electric wire pressing piece when the lid portion is closed, the detection electric wire is easily pushed into the electric wire housing groove portion as the lid portion rotates in the closing direction.
　本発明の電池配線モジュールにおいては、前記電線収納溝部の内底壁面に近い前記複数の電線押え片の下面側で、前記切欠き穴の前記内周縁部と前記複数の電線押え片とが、同一高さの電線経路規制面を形成していてもよい。この構成により、蓋部が閉じると、電線収納溝部内の複数の検知電線が電線押え片によって部分的に押圧されることがなく、検知電線にダメージを与え難くなるので、信頼性の高い電池配線モジュールとなる。 In the battery wiring module of the present invention, the inner peripheral edge portion of the notch hole and the plurality of wire holding pieces are the same on the lower surface side of the plurality of wire holding pieces near the inner bottom wall surface of the wire housing groove. A height electric wire path regulating surface may be formed. With this configuration, when the lid is closed, the multiple detection wires in the wire storage groove are not partially pressed by the wire holding piece, and it is difficult to damage the detection wires. It becomes a module.
　本発明は、複数の電線に外装され該電線を保護する樹脂製保護カバーで構成されるプロテクタであって、前記複数の電線を収納する電線収納溝部と、前記電線収納溝部の両側壁のうち一方の側壁にヒンジ結合し、前記電線収納溝部を閉塞する蓋部と、前記電線収納溝部の内底壁面から離れる前記一方の側壁の上部側に、前記電線収納溝部の内方に向って突出するように設けられた複数の電線押え片と、を有しており、前記蓋部に、前記電線収納溝部を閉塞するときに前記複数の電線押え片のいずれかを収容しつつ前記一方の側壁の上部側に露出させる切欠き穴が形成されている構成とすることもできる。その場合も、電線の一部が電線押え片の基端側や蓋部のヒンジ側にはみ出し得る位置にあったとしても、それを切欠き穴を通して外部から容易に視認でき、切欠き穴を通して電線収納溝部側に押し込むこともできる。したがって、電線が噛み込んだままになることを確実に防止することができる電池配線モジュールに好適なプロテクタとなる。 The present invention is a protector comprising a resin protective cover that is externally covered by a plurality of electric wires and protects the electric wires, and one of the electric wire storage groove portion for storing the plurality of electric wires and both side walls of the electric wire storage groove portion. A lid portion that is hinged to the side wall of the wire and closes the wire housing groove portion, and protrudes inward of the wire housing groove portion on the upper side of the one side wall away from the inner bottom wall surface of the wire housing groove portion. A plurality of electric wire pressing pieces provided on the upper side of the one side wall while accommodating one of the electric wire holding pieces when the electric wire storing groove is closed in the lid portion. It can also be set as the structure in which the notch hole exposed to the side is formed. Even in such a case, even if a part of the wire is in a position where it can protrude from the proximal end side of the wire holding piece or the hinge side of the lid, it can be easily seen from the outside through the notch hole, and the electric wire can be seen through the notch hole. It can also be pushed into the storage groove. Therefore, it becomes a protector suitable for the battery wiring module that can reliably prevent the electric wire from being stuck.
　本発明によれば、検知電線の一部が電線押え片の基端側や蓋部のヒンジ側にはみ出し得る位置にあったとしても、それを外部から視認したり電線収納溝部側に押しこんだりすることができ、検知電線が噛み込んだままになることを確実に防止することができる信頼性の高い電池配線モジュールを提供することができる。 According to the present invention, even if a part of the detection electric wire is in a position where it can protrude from the proximal end side of the electric wire holding piece or the hinge side of the lid portion, it can be visually recognized from the outside or pushed into the electric wire storage groove portion side. Therefore, it is possible to provide a highly reliable battery wiring module that can reliably prevent the detection electric wire from being stuck.

　次に作用について説明する。 Next, the operation will be described.
　上述のように構成された本実施形態においては、検知電線２１，２２の一部が電線押え片３７，３８の基端側や蓋部３５，３６のヒンジ結合部３５ａ，３６ａ側にはみ出し得る位置にあったとしても、それを切欠き穴４１，４２を通して外部から容易に視認できる。さらに、そのような検知電線２１，２２の一部を、切欠き穴４１，４２を通して電線収納溝部３３，３４側に押し込むこともできる。 In the present embodiment configured as described above, a position where a part of the detection wires 21 and 22 can protrude to the proximal end side of the wire holding pieces 37 and 38 and the hinge coupling portions 35a and 36a side of the lid portions 35 and 36. Even if it exists, it can be easily visually recognized from the outside through the notch holes 41 and 42. Furthermore, a part of such detection electric wires 21 and 22 can be pushed into the electric wire housing groove portions 33 and 34 through the notches 41 and 42.
　したがって、検知電線２１，２２の一部が樹脂製保護カバー３０内で蓋部３５，３６と電線押え片３７，３８の間に噛み込んだままになるようなことを確実に防止できる。 Therefore, it is possible to reliably prevent a part of the detection wires 21 and 22 from being stuck between the lid portions 35 and 36 and the wire holding pieces 37 and 38 in the protective cover 30 made of resin.
　また、本実施形態では、図３に示すように、切欠き穴４１，４２の内周縁部４１ａ，４２ａが、複数の電線押え片３７，３８のいずれかに対して、少なくとも電線収納溝部３３，３４の溝長さ方向において、隙間ｇ１，ｇ２を隔てている。したがって、電線収納溝部３３，３４の溝長さ方向に隙間ｇ１，ｇ２の大きさを適宜設定することで、検知電線２１，２２の収納状態を容易に目視できるとともに、蓋部３５，３６を閉じる際に電線押え片３７，３８上に検知電線２１，２２の一部がはみ出していたとしても、検知電線２１，２２にダメージを与えることを確実に防止することができる。 In the present embodiment, as shown in FIG. 3, the inner peripheral edge portions 41 a and 42 a of the cutout holes 41 and 42 are at least connected to the wire holding groove portions 33 and 38 with respect to any of the plurality of wire pressing pieces 37 and 38. In the groove length direction of 34, gaps g1 and g2 are separated. Therefore, by appropriately setting the sizes of the gaps g1 and g2 in the groove length direction of the electric wire storage groove portions 33 and 34, the storage state of the detection electric wires 21 and 22 can be easily seen, and the lid portions 35 and 36 are closed. At this time, even if a part of the detection wires 21 and 22 protrudes from the wire holding pieces 37 and 38, the detection wires 21 and 22 can be reliably prevented from being damaged.
　さらに、本実施形態では、複数の電線押え片３７，３８の基端部３７ａ，３８ａが、蓋部３５，３６のヒンジ結合部３５ａ，３６ａの高さ位置より電線収納溝部３３，３４の内底壁面３３ｂ，３４ｂから離れる上方側に位置するとともに、複数の電線押え片３７，３８の突出端部３７ｂ，３８ｂが基端部３７ａ，３８ａより下方側に位置するように傾斜している。したがって、電線押え片３７，３８が少なくとも突出端部側で斜下方に傾斜することになり、検知電線２１，２２を電線収納溝部３３，３４の内方に誘い込み易くなる。しかも、電線収納溝部３３，３４内に入った検知電線２１，２２が外方に飛び出し難くなる。また、蓋部３５，３６を閉じる際に、電線押え片３７，３８上に検知電線２１，２２の一部が出ていたとしても、その検知電線２１，２２が蓋部３５，３６の閉じ方向への回動に伴って電線収納溝部３３，３４内に押し出され易くなる。 Further, in the present embodiment, the base end portions 37a, 38a of the plurality of wire pressing pieces 37, 38 are located at the inner bottoms of the wire receiving groove portions 33, 34 from the height positions of the hinge coupling portions 35a, 36a of the lid portions 35, 36. In addition to being positioned on the upper side away from the wall surfaces 33b, 34b, the protruding end portions 37b, 38b of the plurality of wire pressing pieces 37, 38 are inclined so as to be positioned below the base end portions 37a, 38a. Therefore, the electric wire holding pieces 37 and 38 are inclined obliquely downward at least on the protruding end side, and the detection electric wires 21 and 22 are easily guided into the electric wire housing grooves 33 and 34. In addition, the detection wires 21 and 22 that have entered the wire housing grooves 33 and 34 are less likely to jump out. Further, when the lid portions 35 and 36 are closed, even if a part of the detection wires 21 and 22 is protruding on the wire holding pieces 37 and 38, the detection wires 21 and 22 are closed in the closing direction of the lid portions 35 and 36. It becomes easy to be pushed out into the electric wire accommodation groove parts 33 and 34 with rotation to.

The plurality of electric wire pressing pieces 37 and 38 form electric wire path regulating surfaces 43 and 44 having the same height. Therefore, when the lid portions 35 and 36 are closed, the plurality of detection wires 21 and 22 in the wire housing grooves 33 and 34 are not partially pressed by the wire holding pieces 37 and 38, and the detection wires 21 and 22 are not pressed. Damage can be more reliably prevented and a highly reliable battery wiring module is obtained.

The hinges may be hinged to the inner side walls inside the portions 31 and 32. Moreover, in this embodiment, although the electrode terminal 11 of the plate-shaped battery 12 shall protrude on the same surface, you may protrude on an upper surface and a side surface, for example.
　また、複数の電線押え片３７，３８のうち一部は電線収納溝部３３，３４の両側壁３３ａ，３３ｃ，３４ａ，３４ｃのうちいずれに突設してもよく、切欠き穴４１，４２は、切欠き凹形状に限らず、開口穴形状でもよい。 Further, some of the plurality of electric wire holding pieces 37, 38 may protrude from either of the side walls 33a, 33c, 34a, 34c of the electric wire housing groove portions 33, 34. The shape is not limited to the notched concave shape, and may be an open hole shape.
　電線収納溝部３３，３４の溝長さ方向における複数の電線押え片３７，３８の設置間隔や切欠き穴４１，４２の形成間隔は、勿論任意であり、１つの切欠き穴４１または４２の内方に近接する複数の電線押え片３７または３８が収納されるようにすれば、これらの数が相違することも考えられる。 Of course, the installation interval of the plurality of electric wire holding pieces 37 and 38 and the formation interval of the notch holes 41 and 42 in the groove length direction of the electric wire housing groove portions 33 and 34 are arbitrary, and the inside of one notch hole 41 or 42 is not limited. If a plurality of wire pressing pieces 37 or 38 that are close to each other are accommodated, it is conceivable that these numbers are different.

Therefore, this invention is applicable also to the protector comprised with the resin-made protective cover sheathed by a bundle-shaped some electric wire. Moreover, although the resin protective cover 30 has the two electric wire storage groove portions 33 and 34 as electric wire insertion passages through which the plurality of detection electric wires 21 and 22 are passed, it may be a protector having one electric wire passage. Needless to say.
　よって、本発明をプロテクタに適用する場合、プロテクタは、複数の電線に外装され該電線を保護する樹脂製保護カバーで構成されるプロテクタであって、前記複数の電線を収納する電線収納溝部と、前記電線収納溝部の両側壁のうち一方の側壁にヒンジ結合し、前記電線収納溝部を閉塞する蓋部と、前記電線収納溝部の内底壁面から離れる前記一方の側壁の上部側に、前記電線収納溝部の内方に向って突出するように設けられた複数の電線押え片と、を有しており、前記蓋部に、前記電線収納溝部を閉塞するときに前記複数の電線押え片のいずれかを収容しつつ前記一方の側壁の上部側に露出させる切欠き穴が形成されている構成となる。 Therefore, when the present invention is applied to a protector, the protector is a protector configured by a resin protective cover that is externally covered with a plurality of electric wires and protects the electric wires, and an electric wire storage groove that stores the plurality of electric wires; The electric wire storage on the upper side of the one side wall that is hinged to one of the side walls of the electric wire storage groove and closes the electric wire storage groove and away from the inner bottom wall surface of the electric wire storage groove.
