しかしながら、上記従来のバッテリ接続体にあっては、電圧検知用の端子付き電線をケースの電線挿通溝内に収容して長形の蓋を閉めた際に、長形の蓋の端部が外部の構造物や作業者の手等に引っ掛かりやすく、長形の蓋が不用意に開いてしまうという問題があった。その場合には、電線挿通溝から各電線が飛び出してしまうので、それを防止するために、予め各電線をバンド等でケースに固定しておく必要が生じ、さらに、開いた蓋を再度締め直すという面倒な作業が必要であった。   However, in the above conventional battery connector, when the electric wire with terminal for voltage detection is accommodated in the electric wire insertion groove of the case and the long lid is closed, the end of the long lid is external. There is a problem that the long lid is inadvertently opened due to being easily caught in the structure of the operator or the hand of the operator. In that case, since each electric wire jumps out from the electric wire insertion groove, in order to prevent it, it is necessary to fix each electric wire to the case in advance with a band or the like, and further retighten the opened lid. The troublesome work was necessary.
また、例えばバッテリの電極の位置が低く設定された場合に、車両のパックケースに邪魔されて、端末のバッテリの電極をバッテリ接続体のケース内で外部の電線付き端子に側方(水平方向)からナットで締付接続することが困難になるという問題があった。   For example, when the position of the battery electrode is set low, the battery case of the terminal is obstructed by the pack case of the vehicle, and the terminal of the battery of the terminal is laterally (horizontal) to the terminal with the electric wire in the case of the battery connector Therefore, there is a problem that it is difficult to tighten and connect with a nut.

図2の如く蓋35を閉じた状態で、可撓杆58は電線挿通溝の開口の中央に位置し、可撓杆58に対向して側方の切欠孔72や底部の孔73(図5)が位置する。可撓杆58は電圧検出用の複数本の電線45(図5)と一緒にバンド等の固定材で巻回固定される。従って、可撓杆58が外部の構造物や作業者の手等に引っ掛かり難く、たとえ引っ掛った場合でも、可撓杆58が電線45に一体的に固定されているから、蓋35の不用意な開きが確実に防止される。また、可撓杆58が蓋35の開き防止用の固定部として作用するから、蓋35の端部にロック爪74等のロック部材を配設する必要がなくなる。   With the lid 35 closed as shown in FIG. 2, the flexible rod 58 is positioned at the center of the opening of the wire insertion groove, and faces the flexible rod 58 with a side cutout hole 72 and a bottom hole 73 (FIG. 5). ) Is located. The flexible rod 58 is wound and fixed together with a plurality of electric wires 45 for voltage detection (FIG. 5) with a fixing material such as a band. Therefore, the flexible rod 58 is difficult to be caught by an external structure or an operator's hand. Even when the flexible rod 58 is caught, the flexible rod 58 is integrally fixed to the electric wire 45. Opening is reliably prevented. Further, since the flexible rod 58 functions as a fixing portion for preventing the lid 35 from opening, it is not necessary to provide a lock member such as the lock claw 74 at the end of the lid 35.
また、可撓杆58は電線挿通溝27の内側に向けて電線45の径方向に撓み自在であるから、電線45に密着しやすく、電線45が可撓杆58に向けて外向きに屈曲したりすることが防止され、電線45は少なくとも電線挿通溝27内で真直に配置される。   Further, since the flexible rod 58 can bend in the radial direction of the electric wire 45 toward the inner side of the electric wire insertion groove 27, it is easy to be in close contact with the electric wire 45, and the electric wire 45 bends outward toward the flexible rod 58. The electric wire 45 is arranged straight at least in the electric wire insertion groove 27.
また、可撓杆58を使用しない場合(電線45を固定材で結束しない等の場合)は、例えば可撓杆58をヒンジから内向きに折り曲げて電線挿通溝27内に隠すことができる。これにより、可撓杆58が邪魔になったり、突出した可撓杆58で外観を損なったりすることがなくなる。   When the flexible rod 58 is not used (when the electric wire 45 is not bundled with a fixing material), for example, the flexible rod 58 can be bent inward from the hinge and hidden in the electric wire insertion groove 27. Thereby, the flexible rod 58 does not get in the way, and the appearance of the protruding flexible rod 58 is not impaired.
蓋35のヒンジ56とは反対側の回動端にはロック爪74が直交して複数並列に設けられている。ロック爪74は外面に突起74aを有し、電線挿通溝27の内側壁28の外面に、ロック爪74に対する係合枠片75(図5)が設けられている。係合枠片75はバスバー収容部4の内側壁と平行な電線挿通溝27の内側壁28との間の隙間に配置されている。   A plurality of lock claws 74 are orthogonally arranged at the rotation end of the lid 35 on the opposite side to the hinge 56 in parallel. The lock claw 74 has a protrusion 74 a on the outer surface, and an engagement frame piece 75 (FIG. 5) for the lock claw 74 is provided on the outer surface of the inner wall 28 of the wire insertion groove 27. The engaging frame piece 75 is disposed in a gap between the inner wall of the bus bar housing portion 4 and the inner wall 28 of the wire insertion groove 27 parallel to the inner wall.
電線挿通溝27の内側壁28には略U字状の可撓ヒンジ76(図5)が形成され、可撓ヒンジ76に対向して外側壁34に切欠スリット77が設けられ、電線挿通溝27は各バスバー収容部4と共に長手方向に伸縮して位置ずれを吸収可能である。   A substantially U-shaped flexible hinge 76 (FIG. 5) is formed on the inner wall 28 of the wire insertion groove 27, and a notch slit 77 is provided on the outer wall 34 so as to face the flexible hinge 76. Can be expanded and contracted in the longitudinal direction together with each bus bar accommodating portion 4 to absorb the displacement.
