請求項２記載の本発明は、請求項１記載の本発明において、前記突出部は、突出方向に向かうに従って前記配列方向の寸法が徐々に小さくなるように形成されていることを特徴とする。   According to a second aspect of the present invention, in the first aspect of the present invention, the projecting portion is formed such that the dimension in the arrangement direction gradually decreases toward the projecting direction.

請求項３記載の本発明は、請求項１又は請求項２記載の本発明において、前記配索部に並設されて、前記各バスバ、及び、前記各端子を収容する複数の収容部と、前記カバーに連続されているとともに、前記収容部と連結された連結部と、をさらに備え、前記連結部には、係止部が設けられ、前記配索部は、底壁と、該底壁から立設して互いに対向する一対の対向壁と、を備え、前記一対の対向壁のうち、前記収容部から離れた側の一方の前記対向壁には、前記突出部が設けられ、前記収容部に近接した側の他方の前記対向壁には、その外面に、前記係止部に係止される係止受け部が設けられ、前記係止部が前記係止受け部に係止されることにより、前記カバーによって前記配索部の開口を覆った状態が維持されることを特徴とする。   According to a third aspect of the present invention, in the first or second aspect of the present invention, a plurality of accommodating portions that are arranged in parallel to the routing portion and accommodate the bus bars and the terminals, A connecting portion that is continuous with the cover and that is connected to the housing portion, the locking portion being provided in the connecting portion, and the routing portion having a bottom wall and the bottom wall A pair of opposing walls that are erected from each other, and one of the pair of opposing walls that is away from the accommodating portion is provided with the protruding portion, and the accommodating portion The other opposing wall on the side close to the portion is provided with a locking receiving portion locked to the locking portion on the outer surface, and the locking portion is locked to the locking receiving portion.

Features.

請求項５記載の本発明は、正極及び負極が交互に逆向きに重ね合わされた複数の電池から構成された電池集合体と、請求項１乃至請求項３のうちいずれか一項に記載されたバスバモジュールと、を備えたことを特徴とする電源装置である。   The invention according to claim 5 is described in any one of claims 1 to 3, and a battery assembly including a plurality of batteries in which positive electrodes and negative electrodes are alternately stacked in opposite directions. And a bus bar module.

請求項１、５記載の本発明によれば、ケースには、電池の配列方向に沿って設けられて、端子に接続される電線を配列方向に沿って配索させる樋形状の配索部と、該配索部の開口を覆うカバーと、が設けられ、配索部とカバーとの間には、配索部とカバーとのうちいずれか一方から突出して形成されて、他方に当接される突出部が設けられている。配索部とカバーとの間には、突出部が設けられているから、カバーが配索部の開口を覆った状態で、他方は、一方に形成された突出部に当接されることとなり、配索部とカバーとの接触面積が小さくされるから、一方と他方との間で生じる電線の噛み込みを抑制することができる。   According to the first and fifth aspects of the present invention, the case is provided with a hook-shaped routing portion that is provided along the arrangement direction of the batteries and that wires the wires connected to the terminals along the arrangement direction. A cover that covers the opening of the routing portion is provided, and is formed between the routing portion and the cover so as to protrude from one of the routing portion and the cover and is in contact with the other. A protrusion is provided. Since the protruding portion is provided between the routing portion and the cover, the other side comes into contact with the protruding portion formed on one side in a state where the cover covers the opening of the routing portion. Since the contact area between the routing portion and the cover is reduced, it is possible to suppress the biting of the electric wire that occurs between one and the other.

請求項２記載の発明によれば、突出部は、突出方向に向かうに従って配列方向の寸法が徐々に小さくなるように形成されているから、配索部とカバーとの接触面積が、より一層、小さくされ、より一層、配索部内を配索された電線の噛み込み抑制することができる。   According to invention of Claim 2, since the protrusion part is formed so that the dimension of an arrangement direction may become small gradually as it goes to a protrusion direction, the contact area of a routing part and a cover is much more, It is possible to further reduce the biting of the electric wires routed in the routing portion.

請求項３記載の発明によれば、配索部に並設されて、各バスバ、及び、各端子を収容する収容部と、カバーに連続されているとともに、収容部と連結された連結部と、をさらに備え、連結部には、係止部が設けられ、配索部は、底壁と、該底壁から立設して互いに対向する一対の対向壁と、を備え、一対の対向壁のうち、収容部から離れた側の一方の対向壁には、突出部が設けられ、収容部に近接した側の他方の対向壁には、その外面に、係止部に係止される係止受け部が設けられ、係止部が係止受け部に係止されることにより、カバーによって配索部の開口を覆った状態が維持される。ここで、従来技術において、係止受け部は、配索溝の開口縁部に設けられていて、係止部の係止受け部への係止力は、配索溝の開口縁部に直接作用していたから、信号線を噛み込んだ場合には、配索溝の開口縁部と溝カバーとの間に隙間を生じさせるように撓ませることができず、信号線を配索溝に収容する際の作業性が悪かったが、配索部の開口から離れた位置で、係止部を係止受け部に係止させることで、係止部の係止受け部への係止力が、配索部とカバーとの接触部分に直接作用しないから、例えば、配索部とカバーとの間で電線を噛み込むことがあっても、一方（例えばカバー）を、配索部とカバーとの間に隙間が生じるように撓ませることにより、他方（例えば配索部）に電線を押し込むことができる。よって、電線を配索部に収容する際の作業性の向上を図ることができる。   According to invention of Claim 3, it is arranged in parallel by the routing part, The accommodating part which accommodates each bus bar and each terminal, The connection part connected with the accommodating part while being connected to the cover, The connecting portion is provided with a locking portion, and the routing portion is provided with a bottom wall and a pair of facing walls that stand from the bottom wall and face each other, and a pair of facing walls One of the opposing walls on the side away from the housing portion is provided with a protrusion, and the other opposing wall on the side close to the housing portion is engaged with the engaging portion on the outer surface thereof. The stop receiving part is provided, and the state in which the opening of the wiring part is covered by the cover is maintained by locking the locking part to the locking receiving part. Here, in the prior art, the latch receiving portion is provided at the opening edge of the routing groove, and the locking force of the locking portion to the latch receiving portion is directly applied to the opening edge of the routing groove. Because it worked, when the signal line is bitten, it cannot be bent so as to create a gap between the opening edge of the wiring groove and the groove cover, and the signal line is accommodated in the wiring groove. Although the workability at the time was bad, by locking the locking part to the locking receiving part at a position away from the opening of the routing part, the locking force to the locking receiving part of the locking part is Since the wire does not act directly on the contact portion between the routing portion and the cover, for example, even if an electric wire is bitten between the routing portion and the cover, one side (for example, the cover) is connected between the routing portion and the cover. The electric wire can be pushed into the other (for example, the routing portion) by bending the gap so that a gap is generated between them. Therefore, the workability | operativity at the time of accommodating an electric wire in a wiring part can be aimed at.

請求項４記載の発明によれば、係止部及び係止受け部は、突出部の配列方向側に位置をずらされて設けられているから、さらに、配索部の開口から離れた位置で、係止部を係止受け部に係止させることができる。また、突出部と対向する位置に、配索部内に電線を導入するための導入口が設けられていた場合には、電線に干渉することなく、係止部を係止受け部に係止させることができる。   According to invention of Claim 4, since the latching | locking part and the latching receiving part are shifted and provided in the sequence direction side of the protrusion part, it is further in the position away from the opening of the routing part. The locking portion can be locked to the locking receiving portion. Further, when an introduction port for introducing the electric wire into the routing portion is provided at a position facing the protruding portion, the engaging portion is engaged with the engaging receiving portion without interfering with the electric wire. be able to.

続いて、上記構成の電源装置１０の組み立て手順を、図３を参照して説明する。まず、バスバ３、電圧検出用端子４、ケース６などを別々に製造しておく。そして、各バスバ３をケース６の各バスバ収容部７に押し込んで係止爪７３Ａで係止する。さらに、バスバ３に電圧検出用端子４を重ねるようにバスバ収容部７に押し込んで係止爪７３Ｂで係止する。バスバ収容部７に設けられた基壁７Ｂ側の開口とバスバ３に設けられた一対の貫通孔３ａとが重なるとともに、バスバ収容部７、及びバスバ３の一対の貫通孔３ａのうち一方に電圧検出用端子４に設けられた貫通孔４ａが重なる。さらに、各電圧検出用端子４に各電圧検出線５の一端部を接続する。各電圧検出線５の他端側を、導入口８Ａ内に挿入させて、配索部８内に配索させる。   Next, an assembly procedure of the power supply apparatus 10 having the above configuration will be described with reference to FIG. First, the bus bar 3, the voltage detection terminal 4, the case 6 and the like are manufactured separately. Then, each bus bar 3 is pushed into each bus bar accommodating portion 7 of the case 6 and locked by the locking claws 73A. Further, the voltage detection terminal 4 is pushed onto the bus bar 3 so as to overlap the bus bar 3 and locked by the locking claws 73B. The opening on the base wall 7B side provided in the bus bar housing portion 7 and the pair of through holes 3a provided in the bus bar 3 are overlapped, and a voltage is applied to one of the bus bar housing portion 7 and the pair of through holes 3a of the bus bar 3. The through holes 4a provided in the detection terminal 4 overlap. Further, one end of each voltage detection line 5 is connected to each voltage detection terminal 4. The other end side of each voltage detection line 5 is inserted into the introduction port 8 </ b> A and routed in the routing unit 8.

そして、回動部９を図３（Ａ）に示す開位置から、１８０度回動させて図３（Ｂ）に示す閉位置に位置付ける。すると、規制片９５がバスバ収容部７の基壁７Ｂに当接する。また、係止部９４が係止受け部８４内に進入して、爪部が係止受け部８４の下端に係止される。これと同時に、カバー９１が、突出部８３の頂部に接触されて、配索部８の開口の一部が覆われる。   And the rotation part 9 is rotated 180 degree | times from the open position shown to FIG. 3 (A), and is located in the closed position shown in FIG. 3 (B). Then, the restriction piece 95 comes into contact with the base wall 7 </ b> B of the bus bar housing portion 7. Further, the locking portion 94 enters the locking receiving portion 84 and the claw portion is locked to the lower end of the locking receiving portion 84. At the same time, the cover 91 is brought into contact with the top of the protruding portion 83 to cover a part of the opening of the routing portion 8.

このように、配索部８とカバー９１との間には、突出部８３が設けられているから、カバー９１が配索部８の開口を覆った状態で、カバー９１及び配索部８のそれぞれに対向面が設けられ、カバー９１の対向面は、配索部８に形成された突出部の頂部に当接されることとなり、配索部８とカバー９１との接触面積が小さくされるから、配索部８とカバー９１との間で生じる電圧検出線５の噛み込みを抑制することができる。 Thus, since the protrusion part 83 is provided between the routing part 8 and the cover 91, the cover 91 and the routing part 8 are in a state where the cover 91 covers the opening of the routing part 8. Each is provided with a facing surface , and the facing surface of the cover 91 is brought into contact with the top of the protruding portion formed in the routing portion 8 so that the contact area between the routing portion 8 and the cover 91 is reduced. Therefore, it is possible to suppress the biting of the voltage detection line 5 that occurs between the routing unit 8 and the cover 91.

ここで、例えば、配索部８とカバー９１との間で電圧検出線５を噛み込むことがあっても、配索部８の開口から離れた位置で、係止部９４を係止受け部８４に係止させることにより係止部９４の係止受け部８４への係止力を、配索部８とカバー９１との接触部分に直接作用させないから、カバー９１を、配索部８とカバー９１との間に隙間を生じさせるように撓ませることにより、配索部８内に電圧検出線５を押し込むことができる。こうして、バスバモジュール１の組み立てが完了する。   Here, for example, even if the voltage detection line 5 is bitten between the routing portion 8 and the cover 91, the locking portion 94 is held at a position away from the opening of the routing portion 8. Since the locking force of the locking portion 94 to the locking receiving portion 84 is not directly applied to the contact portion between the routing portion 8 and the cover 91 by being locked by the locking portion 84, the cover 91 is connected to the routing portion 8. The voltage detection line 5 can be pushed into the routing portion 8 by bending the cover 91 so as to create a gap. Thus, the assembly of the bus bar module 1 is completed.

上述した手順で組み立てられたバスバモジュール１は、電池集合体２の上面に重ねられ、ケース６の基壁７Ｂ側の開口、バスバ３の貫通孔３ａ、電圧検出用端子４の貫通孔４ａを挿入された正極２２、及び負極２３にナットが螺合されて、電池２０の電極２２、２３、バスバ３及び電圧検出線５が電気的に接続されて、電源装置１０の組み立てが完了する。   The bus bar module 1 assembled in the above-described procedure is overlaid on the upper surface of the battery assembly 2, and the opening on the base wall 7B side of the case 6, the through hole 3a of the bus bar 3, and the through hole 4a of the voltage detection terminal 4 are inserted. The nuts are screwed into the positive electrode 22 and the negative electrode 23, and the electrodes 22, 23, the bus bar 3, and the voltage detection line 5 of the battery 20 are electrically connected, and the assembly of the power supply device 10 is completed.
