しかしながら、現在の電池集合体は、高電圧化に伴い、電池の重なり方向の数が多くなる事により、累積公差（各電池ごとの公差が累積して生じる公差）が従来品に比べて大きくなっていることから、この現在の電池集合体に前述した従来のバスバモジュール１００を取り付けようとした場合、以下に示す問題があった。   However, with current battery assemblies, as the voltage increases, the number of batteries in the stacking direction increases, so the cumulative tolerance (tolerance generated by the accumulated tolerance of each battery) becomes larger than that of the conventional product. Therefore, when the above-described conventional bus bar module 100 is attached to the current battery assembly, there are the following problems.

即ち、従来のバスバモジュール１００は、各バスバ１０５，１０５’と各電極との僅かな位置ずれを調整するピッチ調整手段１０７が設けられてはいたが、電池集合体にプラスの累積公差が生じてプレート１１６が引き伸ばされる場合に備えて端子１２８に接続された電線１３２に予め余長、即ちたるみ、を持たせておく必要があり、「プレート１１６が引き伸ばされても電線１３２につっぱりが生じないようにするための対策」として、「端子１２８に接続された電線１３２に予め余長、即ちたるみ、を持たせておく」ことは想到し得るが、電線１３２に余長を持たせた状態にしてプレート１１６に収容する作業は煩雑であるという問題があった。また、プレート１１６に収容された電線１３２が全体的にたるんだ状態であると、この電線１３２がばたついたり過度に屈曲されたり他部品に引っ掛かったりするおそれがあるので、電線１３２を単純にたるませた状態としておくのは好ましくない。さらに、電池集合体は、マイナスの累積公差が生じる場合、即ちプレート１１６を縮めなければならない場合、もあり、その場合は、前述した電線１３２のたるみ量がさらに大きくなるので、「電線１３２がばたついたり過度に屈曲されたり他部品に引っ掛かったりする」ことを防止する手段を設けることがさらに重要になる。   That is, the conventional bus bar module 100 is provided with the pitch adjusting means 107 that adjusts a slight positional deviation between each bus bar 105, 105 ′ and each electrode, but a positive cumulative tolerance occurs in the battery assembly. In preparation for the case where the plate 116 is stretched, it is necessary to provide the wire 132 connected to the terminal 128 with an extra length, that is, a slack, in advance. “Even if the plate 116 is stretched, the wire 132 is not pulled. It is conceivable that “the wire 132 connected to the terminal 128 has a surplus length, that is, a slackness in advance” as a measure for making it, but the wire 132 has a surplus length. There is a problem that the operation of accommodating the plate 116 is complicated. Further, if the electric wire 132 accommodated in the plate 116 is in an overall slack state, the electric wire 132 may flutter, bend excessively, or be caught by other parts. It is not preferable to leave it in a slack state. Further, the battery assembly may have a negative cumulative tolerance, that is, the plate 116 must be contracted. In this case, the amount of sag of the electric wire 132 is further increased. It becomes even more important to provide a means for preventing “shaking, excessive bending, or being caught by other parts”.

そこで、本発明は、上記のような問題点に着目し、電池集合体に取り付けるのに好適なバスバモジュール、及び、前記バスバモジュールを容易に組み立てるための組み立て方法を提供することを目的とする。   Accordingly, the present invention focuses on the above-described problems, and an object thereof is to provide a bus bar module suitable for being attached to a battery assembly, and an assembly method for easily assembling the bus bar module.

The bottom wall 21a positions a connection portion between the electric wire 8 and the terminal 7 on the surface. The “connection portion” means the wire attachment portion 73 and the wire connection portion 72 of the terminal 7 and one end of the electric wire 8 to which the wire attachment portion 73 and the wire connection portion 72 are attached. Further, one end of the electric wire 8 accommodated in the electric wire accommodating portion 20 is bent by approximately 90 degrees and accommodated in the third accommodating portion 21.

上記第１ヒンジ１３は、図３及び図５などに示すように、互いに隣接する第１収容部１２の周壁１２ｂ同士を連結しており、弾性変形自在に形成されている。また、第１ヒンジ１３は、断面Ｃ字形状に形成されており、Ｃ字形状の両端部が互いに近付く方向、または、Ｃ字形状の両端部が互いに離れる方向に弾性変形すること、即ち伸縮するように弾性変形することで、互いに隣接する第１収容部１２間の間隔を変更させる。また、このような第１ヒンジ１３は、１つの第１収容部１２おきに配置されている。また、図３中のＶ１、図６中のＶ２、図７中のＶ３は、それぞれ、互いに隣接する第１収容部１２間の間隔を表している。   As shown in FIGS. 3 and 5, the first hinge 13 connects the peripheral walls 12 b of the first accommodating portions 12 adjacent to each other, and is formed to be elastically deformable. The first hinge 13 is formed in a C-shaped cross section, and elastically deforms, that is, expands and contracts in a direction in which both ends of the C-shape approach each other, or in a direction in which both ends of the C-shape are separated from each other. Thus, the space | interval between the 1st accommodating parts 12 adjacent to each other is changed by elastically deforming. Further, such first hinges 13 are arranged every other first accommodating portion 12. Further, V1 in FIG. 3, V2 in FIG. 6, and V3 in FIG. 7 each represent a distance between the first accommodating portions 12 adjacent to each other.

上記第２ヒンジ１５は、図３及び図４などに示すように、互いに隣接する第２収容部１４同士を連結しており、弾性変形自在に形成されている。また、第２ヒンジ１５は、断面Ｃ字形状に形成されており、Ｃ字形状の両端部が互いに近付く方向、または、Ｃ字形状の両端部が互いに離れる方向に弾性変形すること、即ち伸縮するように弾性変形することで、互いに隣接する第２収容部１４間の間隔を変更させる。また、第２ヒンジ１５は、複数の電線８の配索経路上の障害物となることを避けるために、第２収容部１４の矢印Ｚ方向の両端部それぞれに対をなして配置されている。また、このような第２ヒンジ１５は、１つの第２収容部１４おきに配置されている。また、図３中のＷ１、図６中のＷ２、図７中のＷ３は、それぞれ、互いに隣接する第２収容部１４間の間隔を表している。   As shown in FIGS. 3 and 4, the second hinge 15 connects the second accommodating portions 14 adjacent to each other, and is formed to be elastically deformable. The second hinge 15 is formed in a C-shaped cross section, and elastically deforms, that is, expands and contracts in a direction in which both ends of the C-shape approach each other, or in a direction in which both ends of the C-shape are separated from each other. Thus, the space | interval between the 2nd accommodating parts 14 adjacent to each other is changed by elastically deforming. Further, the second hinges 15 are arranged in pairs at both end portions in the arrow Z direction of the second housing portion 14 in order to avoid an obstacle on the routing route of the plurality of electric wires 8. . Further, such second hinges 15 are arranged every other second accommodating portion 14. Further, W1 in FIG. 3, W2 in FIG. 6, and W3 in FIG. 7 each represent an interval between the second accommodating portions 14 adjacent to each other.

上記固定部１８は、底壁１４ａから円柱状に突出した２つの突出物で構成されている。この２つの突出物は、プレート１１の幅方向に沿って、即ち矢印Ｚに沿って、互いに間隔をあけて配置されており、互いの間に複数の電線８を挟むことでこれら複数の電線８を固定する。   The fixing portion 18 is composed of two protrusions protruding in a columnar shape from the bottom wall 14a. The two protrusions are arranged along the width direction of the plate 11, that is, along the arrow Z, with a space between each other, and the plurality of electric wires 8 are sandwiched between the plurality of electric wires 8. To fix.

また、前記複数の電線８は、図１などに示すように、前記コネクタに接続された各他端がプレート１１の矢印Ｘ方向の一端に位置付けられ、当該プレート１１の一端から電線収容部２０内をプレート１１の他端側に向かって配索されている。そして、各端子７の電線取付部７３及び電線接続部７２に取り付けられた各電線８の一端、即ち接続部分、が当該電線取付部７３及び電線接続部７２が収容された第３収容部２１内に収容されている。さらに、このようにして配索された複数の電線８は、電線収容部２０内において、前述した固定部１８によって固定されている。   Further, as shown in FIG. 1 and the like, each of the plurality of electric wires 8 has the other end connected to the connector positioned at one end in the arrow X direction of the plate 11, and from the one end of the plate 11 to the inside of the electric wire housing 20. Is routed toward the other end of the plate 11. Then, one end of each electric wire 8 attached to the electric wire attaching portion 73 and the electric wire connecting portion 72 of each terminal 7, that is, the connecting portion is in the third accommodating portion 21 in which the electric wire attaching portion 73 and the electric wire connecting portion 72 are accommodated. Is housed in. Further, the plurality of electric wires 8 arranged in this manner are fixed by the fixing portion 18 described above in the electric wire accommodating portion 20.

さらに、上述した複数の電線８は、それぞれ、公差範囲内の最大寸法に形成された電池集合体２の各電極３１，３２に接続可能な位置に各バスバ６が位置付けられた状態のプレート１１の前記一端から各電線８の前記接続部分を収容する第３収容部２１まで届く長さに形成されている。   Further, the plurality of electric wires 8 described above are formed on the plate 11 in a state where each bus bar 6 is positioned at a position connectable to each electrode 31, 32 of the battery assembly 2 formed in the maximum dimension within the tolerance range. The length is formed so as to reach from the one end to the third accommodating portion 21 that accommodates the connecting portion of each electric wire 8.

即ち、プレート１１は、電池３の重なり方向である複数の第１収容部１２の並び方向に沿って最大に引き伸ばされた状態で、図６に示すように、互いに隣接する第１収容部１２間の間隔がＶ２であり、互いに隣接する第２収容部１４間の間隔がＷ２となっており、この状態でのプレート１１の前記一端に位置するバスバ６の穴６１からプレート１１の前記他端に位置するバスバ６の穴６１までの間隔が、公差範囲内の最大寸法に形成された電池集合体２の矢印Ｘ方向の一端に位置する電極３１，３２から電池集合体２の矢印Ｘ方向の他端に位置する電極３１，３２までの間隔よりも大きくなるように形成されている。   That is, the plate 11 is stretched to the maximum along the arrangement direction of the plurality of first accommodating portions 12 that are the overlapping direction of the batteries 3, as shown in FIG. 6, between the first accommodating portions 12 adjacent to each other. The distance between the second accommodating portions 14 adjacent to each other is W2, and the hole 61 of the bus bar 6 located at the one end of the plate 11 in this state is connected to the other end of the plate 11. The distance to the hole 61 of the bus bar 6 positioned from the electrodes 31 and 32 positioned at one end in the arrow X direction of the battery assembly 2 formed in the maximum dimension within the tolerance range to the other in the arrow X direction of the battery assembly 2 It is formed to be larger than the distance to the electrodes 31 and 32 located at the ends.

そして、本発明では、このようにプレート１１が最大に引き伸ばされた状態で、複数の電線８がつっぱりを生じない程度にまっすぐに伸ばされた状態で固定部１８に固定されてプレート１１に収容されている。このため、公差範囲内の最大寸法に形成された電池集合体２に取り付けられる際のプレート１１は、図６に示す最大に引き伸ばされた状態よりも緩んだ状態、即ち引き伸ばし量が小さい状態、となるので、本バスバモジュール１が公差範囲内の最大寸法に形成された電池集合体２に取り付けられる場合でも、電線８につっぱりが生じることがない。即ち、図６に示す状態よりも電線８が引っ張られることがない。   And in this invention, in the state which the plate 11 was extended to the maximum in this way, it fixes to the fixing | fixed part 18 in the state where the some electric wire 8 was extended straightly so that it may not be pulled, and is accommodated in the plate 11 ing. For this reason, the plate 11 when being attached to the battery assembly 2 formed in the maximum dimension within the tolerance range is in a loosened state, that is, a state in which the amount of extension is small, compared to the state shown in FIG. Therefore, even when the present bus bar module 1 is attached to the battery assembly 2 formed to the maximum dimension within the tolerance range, the electric wire 8 is not pulled. That is, the electric wire 8 is not pulled more than the state shown in FIG.

また、本発明では、図３に示すプレート１１が引き伸ばされていない状態、即ち第１ヒンジ１３や第２ヒンジ１５などが非変形の状態、では、互いに隣接する第１収容部１２間の間隔が、図６に示すＶ２よりも小さいＶ１となり、互いに隣接する第２収容部１４間の間隔が、図６に示すＷ２よりも小さいＷ１となる分、対をなす固定部１８間において複数の電線８に余長、即ちたるみ、が生じる。しかしながら、本発明では、各固定部１８においてこれら複数の電線８が固定されているので、一箇所に大きな余長、即ちたるみ、が集中することがなく、そのために、当該電線８がばたついたり過度に屈曲されたり他部品に引っ掛かったりするおそれがない。   In the present invention, when the plate 11 shown in FIG. 3 is not stretched, that is, when the first hinge 13 and the second hinge 15 are not deformed, the distance between the first accommodating portions 12 adjacent to each other is A plurality of electric wires 8 are formed between the pair of fixed portions 18 so that V1 is smaller than V2 shown in FIG. 6 and the interval between the second accommodating portions 14 adjacent to each other is W1 smaller than W2 shown in FIG. In this case, an extra length, that is, sagging occurs. However, in the present invention, since the plurality of electric wires 8 are fixed at each fixing portion 18, a large extra length, that is, sagging is not concentrated in one place, and therefore the electric wires 8 flutter. There is no risk of being bent or excessively bent or caught by other parts.

また、本発明では、図７に示すプレート１１が縮められた状態、即ち第１ヒンジ１３や第２ヒンジ１５などが縮められた状態、では、互いに隣接する第１収容部１２間の間隔が、図３に示すＶ１よりも小さいＶ３となり、互いに隣接する第２収容部１４間の間隔が、図３に示すＷ１よりも小さいＷ３となる分、対をなす固定部１８間において複数の電線８にさらなる余長、即ちたるみ、が生じる。しかしながら、本発明では、前述したように、各固定部１８においてこれら複数の電線８が固定されているので、一箇所に大きな余長、即ちたるみ、が集中することがなく、そのために、当該電線８がばたついたり過度に屈曲されたり他部品に引っ掛かったりするおそれがない。   Further, in the present invention, in a state where the plate 11 shown in FIG. 7 is contracted, that is, in a state where the first hinge 13 and the second hinge 15 are contracted, the interval between the first accommodating portions 12 adjacent to each other is V3 is smaller than V1 shown in FIG. 3, and the interval between the second accommodating portions 14 adjacent to each other is W3 smaller than W1 shown in FIG. 3. Further extra length, i.e. sagging, occurs. However, in the present invention, as described above, since the plurality of electric wires 8 are fixed in each fixing portion 18, a large extra length, that is, a slack is not concentrated in one place. There is no possibility that 8 will flutter, bend excessively, or be caught by other parts.

即ち、本発明のバスバモジュール１は、プレート１１が引き伸ばされても電線８につっぱりが生じないようにするための余長を複数個所で確保しつつ、当該電線８を複数個所で固定しているので、累積公差が大きい（±１０ｍｍ〜１５ｍｍ）電池集合体２に取り付けるのに好適となる。   That is, the bus bar module 1 according to the present invention secures the electric wires 8 at a plurality of locations while securing extra lengths at the plurality of locations so that the electric wires 8 are not pulled even when the plate 11 is stretched. Therefore, it becomes suitable for attaching to the battery assembly 2 having a large accumulated tolerance (± 10 mm to 15 mm).

また、各サーミスタに接続された複数の電線の収容構造についての詳細な説明は省略するが、この電線についても、前述した電線８と同様に、電池集合体２の寸法に応じて伸縮するプレート１１に対応したつっぱりを生じないための余長が確保され、かつ、固定部１８と同様の電線固定手段が設けられた収容構造となっている。   Moreover, although detailed description about the accommodation structure of the some electric wire connected to each thermistor is abbreviate | omitted, the plate 11 which expands-contracts according to the dimension of the battery assembly 2 also about this electric wire similarly to the electric wire 8 mentioned above. The housing structure is provided with a surplus length for preventing the occurrence of pulling corresponding to, and provided with electric wire fixing means similar to the fixing portion 18.

続いて、上記構成のバスバモジュール１の組み立て方法について説明する。バスバモジュール１を組み立てる際は、プレート１１、バスバ６、端子７、などを別々に製造しておき、次に、各第１収容部１２に各バスバ６を嵌め込む（バスバ６をプレート１１にインサート成形するようにしても良い。）。次に、プレート１１を複数の第１収容部１２の並び方向に沿って、即ち矢印Ｘ方向に沿って、最大に引き伸ばし、この状態を維持する（請求項中の「プレート引き伸ばし工程」に相当する。）。次に、複数の電線８をまっすぐに伸ばした状態で固定部１８を構成する２つの前記突出物間に押し込むことで、引き伸ばされたプレート１１の電線収容部２０に複数の電線８を収容し、各電線８と各端子７との前記接続部分を所定の第３収容部２１に収容するとともに（請求項中の「収容工程」に相当する。）、各電線８に接続された各端子７のバスバ接続部７１を各バスバ６の上に重ねるようにして各第１収容部１２に嵌め込む。また、これと同様にして複数の電線と各電線に接続された各サーミスタをサーミスタ収容部２７に収容する。そして、引き伸ばされたプレート１１に加えた引っ張り力を解除して、該プレート１１を引き伸ばされていない状態に弾性復帰させる。こうしてバスバモジュール１が組み立てられる。   Then, the assembly method of the bus bar module 1 of the said structure is demonstrated. When assembling the bus bar module 1, the plate 11, the bus bar 6, the terminal 7, etc. are manufactured separately, and then each bus bar 6 is fitted into each first accommodating portion 12 (the bus bar 6 is inserted into the plate 11. It may be molded.) Next, the plate 11 is stretched to the maximum along the direction in which the plurality of first accommodating portions 12 are arranged, that is, along the direction of the arrow X, and this state is maintained (corresponding to the “plate stretching step” in the claims). .) Next, the plurality of electric wires 8 are accommodated in the electric wire accommodating portion 20 of the stretched plate 11 by being pushed between the two protrusions constituting the fixing portion 18 in a state where the plural electric wires 8 are straightened. While accommodating the said connection part of each electric wire 8 and each terminal 7 in the predetermined | prescribed 3rd accommodating part 21 (equivalent to the "accommodating process" in a claim), each terminal 7 connected to each electric wire 8 is used. The bus bar connection portions 71 are fitted into the first accommodating portions 12 so as to overlap the bus bars 6. In the same manner, a plurality of electric wires and the thermistors connected to the electric wires are accommodated in the thermistor accommodating portion 27. Then, the pulling force applied to the stretched plate 11 is released, and the plate 11 is elastically returned to the unstretched state. Thus, the bus bar module 1 is assembled.

さらに、前述した手順で組み立てられたバスバモジュール１は、図８に示す方法で電池集合体２の上面に取り付けられる。即ち、図８（ａ）に示すように、最初にバスバモジュール１の矢印Ｘ方向の一端が電池集合体２の矢印Ｘ方向の一端に重ねられて、この電池集合体２の一端に位置する電極３１，３２がバスバ６の穴６１及び端子７の穴７１ａを通される。そこから図８（ｂ）に示すように、矢印Ｘ方向の他端側に向かって徐々にバスバモジュール１が電池集合体２に重ねられる。この際、電池集合体２にプラスの累積公差が生じている場合は、バスバモジュール１が引き伸ばされながら、電池集合体２の電極３１，３２のピッチに合わせられる。また、電池集合体２にマイナスの累積公差が生じている場合は、バスバモジュール１が縮められながら、電池集合体２の電極３１，３２のピッチに合わせられる。こうして、図８（ｃ）に示すように、バスバモジュール１の全体が電池集合体２に重ねられてこのバスバモジュール１が電池集合体２に取り付けられる。その後、各穴６１，７１ａに通された各電極３１，３２にナットが螺合されることで各電極３１，３２と各バスバ６とが固定されて、前記電源装置が組み立てられる。   Furthermore, the bus bar module 1 assembled in the above-described procedure is attached to the upper surface of the battery assembly 2 by the method shown in FIG. That is, as shown in FIG. 8A, first, one end of the bus bar module 1 in the direction of the arrow X is overlapped with one end of the battery assembly 2 in the direction of the arrow X, and the electrode located at one end of the battery assembly 2 31 and 32 are passed through the hole 61 of the bus bar 6 and the hole 71 a of the terminal 7. 8B, the bus bar module 1 is gradually overlapped with the battery assembly 2 toward the other end side in the arrow X direction. At this time, if a positive cumulative tolerance is generated in the battery assembly 2, the bus bar module 1 is stretched and adjusted to the pitch of the electrodes 31 and 32 of the battery assembly 2. Further, when a negative cumulative tolerance is generated in the battery assembly 2, the bus bar module 1 is contracted and adjusted to the pitch of the electrodes 31 and 32 of the battery assembly 2. Thus, as shown in FIG. 8C, the entire bus bar module 1 is overlaid on the battery assembly 2, and the bus bar module 1 is attached to the battery assembly 2. Thereafter, nuts are screwed into the electrodes 31 and 32 passed through the holes 61 and 71a, so that the electrodes 31 and 32 and the bus bars 6 are fixed, and the power supply apparatus is assembled.

このように、本発明では、引き伸ばされたプレート１１の電線収容部２０に複数の電線８を収容するようにしてバスバモジュール１を組み立てるので、複数の電線８をまっすぐに伸ばした状態で単純に固定部１８を構成する２つの前記突出物間に押し込むことで、複数の電線８と各固定部１８との位置合わせ等を考慮することなく、即ち複数の電線８を余長確保のために曲げる作業を行うことなく、プレート１１が引き伸ばされていない状態で対をなす各固定部１８間に電線８の余長が均等に確保されたバスバモジュールを１を容易に組み立てることができる。   In this way, in the present invention, the bus bar module 1 is assembled so that the plurality of wires 8 are accommodated in the wire accommodating portion 20 of the stretched plate 11, so that the plurality of wires 8 are simply fixed in a state where they are straightened. The operation of bending the plurality of electric wires 8 to secure the extra length without considering the alignment between the plural electric wires 8 and each fixing portion 18 by pushing between the two protrusions constituting the portion 18 1 is easily assembled without securing the extra length of the electric wires 8 between the fixed portions 18 that are paired in a state where the plate 11 is not stretched.

また、上記バスバモジュール１は、プレート１１が引き伸ばされていない状態で対をなす各固定部１８間に電線８の余長が均等に確保されているので、電池集合体２に取り付けられる際にプレート１１が引き伸ばされた場合にも、電線８が部分的に引っ張られることがない。   In addition, the bus bar module 1 is configured such that when the plate 11 is attached to the battery assembly 2, the extra length of the electric wires 8 is ensured evenly between the fixed portions 18 that are paired in a state where the plate 11 is not stretched. Even when 11 is stretched, the electric wire 8 is not partially pulled.

また、上記バスバモジュール１は、第１ヒンジ１３が１つの第１収容部１２おきに配置され、第２ヒンジ１５が１つの第２収容部１４おきに配置されているので、電池集合体２の累積公差による各バスバ６と各電極３１，３２との位置ずれを調整する「調整代」が従来品よりも大きくなる。よって、累積公差が大きい電池集合体２に取り付けるのにさらに好適となる。   Further, in the bus bar module 1, the first hinge 13 is arranged every other first accommodating part 12, and the second hinge 15 is arranged every other second accommodating part 14. The “adjustment allowance” for adjusting the positional deviation between each bus bar 6 and each electrode 31 and 32 due to the accumulated tolerance is larger than that of the conventional product. Therefore, it becomes more suitable for attaching to the battery assembly 2 having a large cumulative tolerance.

また、本実施形態に示すバスバモジュール１は、複数の電線８が収容された第２収容部１４の開口部を覆う蓋部１６を有しているが、本発明では、複数の電線８を固定する、即ち複数の電線８が第２収容部１４から飛び出すことを防止する、固定部１８を有しているので、蓋部１６を省略した構成とすることもできる。その場合は、前記バスバモジュールの軽量化及び簡素化を図ることができ、また、前記プレートの可撓性向上、即ち前記バスバモジュールの電池集合体２への取り付け易さの向上、を図ることができる。   In addition, the bus bar module 1 shown in the present embodiment includes the lid portion 16 that covers the opening of the second housing portion 14 in which the plurality of wires 8 are housed. In the present invention, the plurality of wires 8 are fixed. That is, since it has the fixing | fixed part 18 which prevents the some electric wire 8 jumping out from the 2nd accommodating part 14, it can also be set as the structure which abbreviate | omitted the cover part 16. FIG. In that case, the bus bar module can be reduced in weight and simplified, and the flexibility of the plate can be improved, that is, the ease of attaching the bus bar module to the battery assembly 2 can be improved. it can.

（第２の実施形態）
続いて、本発明の第２の実施形態に係るバスバモジュール、及び、バスバモジュールの組み立て方法を、図９及び図１０を参照して説明する。図９は本発明の第２の実施形態に係るバスバモジュールの一部を示す平面図であり、第１ピッチ調整手段及び第２ピッチ調整手段が非変形の状態の前記バスバモジュールを示す平面図である。図１０は本発明の第２の実施形態に係るバスバモジュールの一部を示す平面図であり、第１ピッチ調整手段及び第２ピッチ調整手段が縮められた状態の前記バスバモジュールを示す平面図である。また、図９及び図１０において、前述した第１の実施形態と同一構成部分には同一符号を付して説明を省略する。 (Second Embodiment)
Subsequently, a bus bar module and a method for assembling the bus bar module according to the second embodiment of the present invention will be described with reference to FIGS. 9 and 10.

本実施形態のバスバモジュール１’は、弾性変形自在の第１ヒンジ１３’（請求項中の第１ピッチ調整手段に相当する。）が、互いに隣接する第１収容部１２同士を連結しており、かつ、弾性変形自在の第２ヒンジ１５’（請求項中の第２ピッチ調整手段に相当する。）が、互いに隣接する第２収容部１４同士を連結したプレート１１’を有している。   In the bus bar module 1 ′ of the present embodiment, a first hinge 13 ′ (corresponding to the first pitch adjusting means in the claims) that is elastically deformable connects the first accommodating portions 12 adjacent to each other. The second hinge 15 ′ that is elastically deformable (corresponding to the second pitch adjusting means in the claims) has a plate 11 ′ that connects the second accommodating portions 14 adjacent to each other.

上記プレート１１’は、図９に示すプレート１１’が引き伸ばされていない状態、即ち第１ヒンジ１３’や第２ヒンジ１５’などが非変形の状態、で、互いに隣接する第１収容部１２間の間隔がＶ２であり、互いに隣接する第２収容部１４間の間隔がＷ２となっており、この状態でのプレート１１’の矢印Ｘ方向の一端に位置するバスバ６の穴６１からプレート１１’の矢印Ｘ方向の他端に位置するバスバ６の穴６１までの間隔が、公差範囲内の最大寸法に形成された電池集合体２の矢印Ｘ方向の一端に位置する電極３１，３２から電池集合体２の矢印Ｘ方向の他端に位置する電極３１，３２までの間隔よりも大きくなるように形成されている。   The plate 11 ′ is in a state in which the plate 11 ′ shown in FIG. The distance between the second accommodating portions 14 adjacent to each other is W2, and the plate 11 ′ from the hole 61 of the bus bar 6 located at one end in the arrow X direction of the plate 11 ′ in this state The battery assembly from the electrodes 31 and 32 positioned at one end in the arrow X direction of the battery assembly 2 formed so that the distance to the hole 61 of the bus bar 6 positioned at the other end in the arrow X direction is the maximum dimension within the tolerance range. It is formed to be larger than the distance to the electrodes 31 and 32 located at the other end of the body 2 in the arrow X direction.

そして、本発明では、このようにプレート１１’が引き伸ばされていない状態で、複数の電線８がつっぱりを生じない程度にまっすぐに伸ばされた状態で固定部１８に固定されてプレート１１’に収容されている。このため、公差範囲内の最大寸法に形成された電池集合体２に取り付けられる際のプレート１１’は、図９に示す、引き伸ばされていない状態よりも縮められた状態となるので、本バスバモジュール１’が公差範囲内の最大寸法に形成された電池集合体２に取り付けられる場合でも、電線８につっぱりが生じることがない。即ち、図９に示す状態よりも電線８が引っ張られることがない。   In the present invention, the plate 11 ′ is not stretched as described above, and is fixed to the fixing portion 18 in a state where the plurality of electric wires 8 are straightly stretched so as not to be pulled, and accommodated in the plate 11 ′. Has been.
