Further, the terminal body member 15A has a communication cable opening 15M into which a communication cable (not shown) used for communication with sensors (not shown) in the assembled battery case 18 is inserted (see FIG. 4A). .

また、正極金属端子１５Ｘは、正極担持部１５ｂＸよりも上述の台座部１８Ｄ側に位置する正極基端部１５Ｘｂを有する（図４（ｂ）参照）。正極金属端子１５Ｘは、この正極基端部１５Ｘｂで、各電池１１のうち最も正電位側の電池の端子（図示しない）と電気的に接続している。
また、この正極金属端子１５Ｘは、正極担持部１５ｂＸから台座部１８Ｄに直交して脱離方向ＤＲ側に突出する正極突出部１５Ｘａ、および、この正極突出部１５Ｘａの先端部分に形成した凹溝状の溝部１５Ｘｃを有する。この正極金属端子１５Ｘは、図３に示すように、後述の正極接続ケーブル２０の正極ケーブル端子本体２１と接続される。 Moreover, the positive electrode metal terminal 15X has the positive electrode base end part 15Xb located in the above-mentioned base part 18D side rather than the positive electrode support part 15bX (refer FIG.4 (b)). The positive electrode metal terminal 15X is electrically connected to the terminal (not shown) of the battery on the most positive potential side among the batteries 11 at the positive electrode base end portion 15Xb.
The positive metal terminal 15X includes a positive electrode protrusion 15Xa that protrudes from the positive electrode carrier 15bX perpendicular to the pedestal 18D toward the detaching direction DR, and a concave groove formed at the tip of the positive electrode protrusion 15Xa. Groove portion 15Xc. As shown in FIG. 3, the positive metal terminal 15 </ b> X is connected to a positive cable terminal body 21 of a positive connection cable 20 described later.

一方、負極金属端子１５Ｙもまた、上述の正極金属端子１５Ｘと同様に、外部接続端子１５の底部１５ｂよりも台座部１８Ｄ側に位置する負極基端部１５Ｙｂを有する。この負極基端部１５Ｙｂは、各電池１１のうち最も負電位側の電池の端子（図示しない）と電気的に接続している。また、負極金属端子１５Ｙも、台座部１８Ｄに直交して、脱離方向ＤＲ側に突出する負極突出部１５Ｙａ、および、この負極突出部１５Ｙａの先端部分に形成した凹溝状の溝部１５Ｙｃを有する。この負極金属端子１５Ｙは、後述の負極接続ケーブル３０の負極ケーブル端子本体３１と接続される。   On the other hand, the negative electrode metal terminal 15Y also has a negative electrode base end portion 15Yb located on the pedestal portion 18D side with respect to the bottom portion 15b of the external connection terminal 15 in the same manner as the positive electrode metal terminal 15X described above. The negative electrode base end portion 15 </ b> Yb is electrically connected to a terminal (not shown) of the battery on the most negative potential side among the batteries 11. The negative electrode metal terminal 15Y also includes a negative electrode protrusion 15Ya that protrudes perpendicularly to the pedestal 18D toward the detaching direction DR, and a groove-shaped groove 15Yc formed at the tip of the negative electrode protrusion 15Ya. . The negative electrode metal terminal 15Y is connected to a negative electrode terminal body 31 of a negative electrode connection cable 30 described later.

次に、正極接続ケーブル２０について、図５を参照しつつ説明する。この正極接続ケーブル２０は、銅製の導線ＣＬを絶縁性樹脂ＰＶで被覆してなる正極ケーブル２４と、この正極ケーブル２４の先端部２４ｄに結合され、外部接続端子１５のうち正極金属端子１５Ｘと着脱可能に接続する正極ケーブル端子２３とを有する。さらに、この正極ケーブル端子２３は、正極ケーブル端子本体２１、およびこれに係合する正極プルタブ２２を有する。なお、この正極ケーブル２４は、正極ケーブル端子２３とは逆側（基端側）で、図示しないインバータ装置と接続している。   Next, the positive electrode connection cable 20 will be described with reference to FIG. The positive connection cable 20 is coupled to a positive cable 24 formed by coating a copper conducting wire CL with an insulating resin PV, and a tip 24d of the positive cable 24, and is attached to and detached from the positive metal terminal 15X among the external connection terminals 15. It has a positive cable terminal 23 that can be connected. Further, the positive cable terminal 23 includes a positive cable terminal main body 21 and a positive pull tab 22 that engages with the positive cable terminal main body 21. The positive cable 24 is connected to an inverter device (not shown) on the side opposite to the positive cable terminal 23 (base end side).

正極ケーブル端子本体２１は、金属からなる正極金属体２１Ａと、この正極金属体２１Ａをほぼ覆ってなる絶縁性樹脂製の正極端子ケース２１Ｃとを有する。このうち、正極金属体２１Ａは、正極金属端子１５Ｘの正極突出部１５Ｘａと接触する有底円筒形状の嵌合部２１Ａｍ、および正極ケーブル２４の先端部２４ｄを周囲から包囲して挟持する挟持部２１Ａｎを含む。   The positive electrode cable terminal main body 21 has a positive electrode metal body 21A made of metal and a positive electrode terminal case 21C made of an insulating resin substantially covering the positive electrode metal body 21A. Among these, the positive electrode metal body 21A includes a bottomed cylindrical fitting portion 21Am that comes into contact with the positive electrode protrusion 15Xa of the positive electrode metal terminal 15X, and a sandwiching portion 21An that surrounds and sandwiches the front end portion 24d of the positive electrode cable 24. including.

このうち、嵌合部２１Ａｍは、この内側面２１Ａｍａに半球状の突起部２１Ａｍｐを複数有する。この突起部２１Ａｍｐは、嵌合部２１Ａｍを正極金属端子１５Ｘの正極突出部１５Ｘａに被せて、この正極突出部１５Ｘａを嵌合部２１Ａｍ内に押し込んだとき、正極金属端子１５Ｘの溝部１５Ｘｃと嵌合して、機械的にも、かつ、電気的にも両者を接続する。   Of these, the fitting portion 21Am has a plurality of hemispherical protrusions 21Amp on the inner surface 21Ama. The protrusion 21Amp is fitted with the groove 15Xc of the positive metal terminal 15X when the fitting 21Am is put on the positive electrode protrusion 15Xa of the positive metal terminal 15X and the positive electrode protrusion 15Xa is pushed into the fitting 21Am. Then, both are connected mechanically and electrically.

一方、正極プルタブ２２は、略コ字状の形態を有し、その両端部に位置する支持部２２Ｔと、これらの中間に位置し、手指を係合して引っ張るのに用いる手指係合部２２Ｓとを有する。この正極プルタブ２２の２つの支持部２２Ｔは、それぞれ一部が正極端子ケース２１Ｃ内に回動可能に挿入されている。これにより、手指係合部２２Ｓを含め正極プルタブ２２全体が、支持部２２Ｔを中心として回動可能である。
従って、例えば、図６（ａ）に示すように、正極プルタブ２２を寝かせる、即ち、手指係合部２２Ｓを正極ケーブル端子本体２１の受け板部２１ＣＭに当接させるようにすると、手指係合部２２Ｓを含めた正極プルタブ２２は、この正極ケーブル端子本体２１のうちで最も脱離方向ＤＲ側に位置する上端面２１Ｃａよりも、脱離方向ＤＲとは逆側（図６中、下方）に位置する。つまり、この状態では、正極プルタブ２２は、正極ケーブル端子本体２１よりも脱離方向ＤＲ側に突出しないようにすることができる。 On the other hand, the positive electrode pull tab 22 has a substantially U-shaped form, a support portion 22T positioned at both ends thereof, and a finger engagement portion 22S that is positioned between them and used for engaging and pulling fingers. And have. A part of each of the two support portions 22T of the positive pull tab 22 is rotatably inserted into the positive terminal case 21C. Thereby, the whole positive electrode pull tab 22 including finger engagement part 22S can be rotated centering on support part 22T.
Therefore, for example, as shown in FIG. 6A, when the positive pull tab 22 is laid down, that is, when the finger engaging portion 22S is brought into contact with the receiving plate portion 21CM of the positive cable terminal main body 21, the finger engaging portion The positive pull tab 22 including 22S is located on the opposite side (downward in FIG. 6) to the detachment direction DR from the upper end surface 21Ca located most on the detachment direction DR side in the positive cable terminal body 21. To do. That is, in this state, the positive electrode pull tab 22 can be prevented from projecting toward the detaching direction DR from the positive cable terminal body 21.

一方、図６（ｂ）に示すように、正極プルタブ２２を起こす、即ち、支持部２２Ｔを中心に正極プルタブ２２を回動させて脱離方向ＤＲに延びる形態とすると、その手指係合部２２Ｓは、上端面２１Ｃａよりも、脱離方向ＤＲに位置する状態となる。
なお、負極接続ケーブル３０についても、正極接続ケーブル２０と同様の形態を有するので、説明を省略する。 On the other hand, as shown in FIG. 6B, when the positive pull tab 22 is raised, that is, when the positive pull tab 22 is rotated around the support portion 22T and extends in the detaching direction DR, the finger engaging portion 22S. Is positioned in the detaching direction DR with respect to the upper end surface 21Ca.
Note that the negative electrode connection cable 30 has the same form as the positive electrode connection cable 20, and therefore the description thereof is omitted.

次に、接続ケーブル２０，３０と組電池１０（外部接続端子１５）とを接続した組電池構造体１について説明する。前述したように、この組電池構造体１では、正極接続ケーブル２０および負極接続ケーブル３０は、その正極ケーブル端子２３および負極ケーブル端子３３が、組電池ケース１８の台座部１８Ｄにおいて、外部接続端子１５に接続している。接続した正極接続ケーブル２０の正極ケーブル端子２３、および、負極接続ケーブル３０の負極ケーブル端子３３は、正極ケーブル２４、負極ケーブル３４が延出する延出方向ＤＡを除く３方向から、外部接続端子１５のうち壁部１５Ｗの内壁面１５Ｗｂに囲まれている。   Next, the assembled battery structure 1 in which the connection cables 20 and 30 and the assembled battery 10 (external connection terminal 15) are connected will be described. As described above, in this assembled battery structure 1, the positive connection cable 20 and the negative connection cable 30 have the positive cable terminal 23 and the negative cable terminal 33 at the pedestal portion 18 </ b> D of the assembled battery case 18. Connected to. The positive electrode cable terminal 23 of the connected positive electrode connection cable 20 and the negative electrode cable terminal 33 of the negative electrode connection cable 30 are connected to the external connection terminal 15 from three directions excluding the extending direction DA in which the positive electrode cable 24 and the negative electrode cable 34 extend. Is surrounded by an inner wall surface 15Wb of the wall portion 15W.

図３に、正極接続ケーブル２０の正極ケーブル端子２３と外部接続端子１５が接続した状態における断面図（図２（ｂ）のＡ−Ａ断面）を示す。正極ケーブル端子２３の正極ケーブル端子本体２１は、その嵌合部２１Ａｍが正極金属端子１５Ｘと嵌合することにより、電気的にも、機械的にも、これと接続している。   FIG. 3 shows a cross-sectional view (A-A cross section in FIG. 2B) in a state where the positive electrode cable terminal 23 of the positive electrode connection cable 20 and the external connection terminal 15 are connected. The positive cable terminal main body 21 of the positive electrode cable terminal 23 is electrically and mechanically connected to the positive electrode metal terminal 15X by fitting the fitting portion 21Am thereof.

なお、この図３から判るように、本実施形態では、外部接続端子１５に正極ケーブル端子２３を接続した状態で、正極ケーブル端子本体２１の上端面２１Ｃａよりも、壁部１５Ｗの内壁面１５Ｗｂのうち、脱離方向ＤＲの端である壁面上端１５Ｗｂａの方が、脱離方向ＤＲの側に位置する形態としてある。つまり、正極ケーブル端子本体２１は、その全体が、脱離方向ＤＲに見て、壁面上端１５Ｗｂａよりも低位とされている。   As can be seen from FIG. 3, in this embodiment, in the state where the positive cable terminal 23 is connected to the external connection terminal 15, the inner wall surface 15 </ b> Wb of the wall portion 15 </ b> W is more than the upper end surface 21 </ b> Ca of the positive cable terminal body 21. Of these, the wall surface upper end 15Wba, which is the end of the detachment direction DR, is located on the detachment direction DR side. That is, the whole positive electrode cable terminal body 21 is lower than the wall surface upper end 15Wba when viewed in the detaching direction DR.

また、正極接続ケーブル２０の正極ケーブル２４は、外部接続端子１５のうちケーブル支持部１５Ｎにより支持されている。このケーブル支持部１５Ｎは、その上面高さが正極ケーブル端子本体２１から延出する正極ケーブル２４の底部高さと同じにしてあり、正極ケーブル２４をほぼまっすぐ保持して、振動等による応力が正極ケーブル２４の先端部２３ｄにかかりにくくしてある。
なお、接続している負極接続ケーブル３０についても、正極接続ケーブル２０と同様にして外部接続端子１５に接続しているので、説明を省略する。 Further, the positive cable 24 of the positive connection cable 20 is supported by the cable support 15 </ b> N of the external connection terminal 15. The cable support portion 15N has the same height as the bottom portion of the positive cable 24 extending from the positive cable terminal body 21, and holds the positive cable 24 substantially straight so that stress due to vibration or the like is positive. 24 is difficult to be applied to the distal end portion 23d.
Note that the connected negative connection cable 30 is also connected to the external connection terminal 15 in the same manner as the positive connection cable 20, and therefore the description thereof is omitted.

次いで、図６を用いて外部接続端子１５から正極接続ケーブル２０の正極ケーブル端子２３を脱離させる手法を示す。
正極ケーブル端子２３を脱離させない場合（通常の場合）には、図６（ａ）に示すように、正極プルタブ２２を寝かせておく。
一方、正極ケーブル端子２３を脱離させるときには、正極プルタブ２２を、支持部２２Ｔを中心に回動させて起こし、その手指係合部２２Ｓを正極端子ケース２１Ｃの上端面２１Ｃａおよび壁部１５Ｗよりも脱離方向ＤＲ（図６中、上方）に位置させる（図６（ｂ）参照）。 Next, a method of detaching the positive electrode cable terminal 23 of the positive electrode connection cable 20 from the external connection terminal 15 will be described with reference to FIG.
When the positive electrode cable terminal 23 is not detached (normal case), the positive electrode pull tab 22 is laid as shown in FIG.
On the other hand, when detaching the positive electrode cable terminal 23, the positive electrode pull tab 22 is raised by rotating around the support portion 22T, and the finger engaging portion 22S is positioned more than the upper end surface 21Ca and the wall portion 15W of the positive electrode terminal case 21C. It is located in the detaching direction DR (upward in FIG. 6) (see FIG. 6B).

その後、この手指係合部２２Ｓに手指を係合する。この際、壁部１５Ｗや正極端子ケース２１Ｃが手指の係合の障害にならないため、容易に手指を手指係合部２２Ｓに係合させることができる。ついで、正極プルタブ２２を脱離方向ＤＲ（図６中、上方）に引っ張る。すると、支持部２２Ｔに係合する正極端子ケース２１Ｃも脱離方向ＤＲに引っ張られ、正極ケーブル端子２３全体を正極金属端子１５Ｘの正極突出部１５Ｘａから脱離させることができる（図６（ｃ））。
なお、外部接続端子１５から負極ケーブル端子３３を脱離させる手法も、上述と同様であるので、説明を省略する。 Thereafter, the fingers are engaged with the finger engaging portions 22S. At this time, since the wall portion 15W and the positive terminal case 21C do not become obstacles to finger engagement, the finger can be easily engaged with the finger engagement portion 22S. Next, the positive electrode pull tab 22 is pulled in the detaching direction DR (upward in FIG. 6). Then, the positive terminal case 21C engaged with the support portion 22T is also pulled in the detaching direction DR, and the entire positive cable terminal 23 can be detached from the positive electrode protrusion 15Xa of the positive metal terminal 15X (FIG. 6C). ).
Note that the method of detaching the negative cable terminal 33 from the external connection terminal 15 is the same as described above, and thus the description thereof is omitted.

以上で説明したように、本実施形態の組電池構造体１において、正極ケーブル端子２３および負極ケーブル端子３３は、それぞれプルタブ２２，３２を備えている。このため、これらプルタブ２２，３２の手指係合部２２Ｓ，３２Ｓに手指を係合して、プルタブ２２，３２を脱離方向ＤＲに引っ張り、正極ケーブル端子２３（負極ケーブル端子３３）を組電池１０の外部接続端子１５から容易に脱離させることができる。また、正極ケーブル端子２３（負極ケーブル端子３３）を脱離させる際、プルタブ２２，３２の手指係合部を脱離方向ＤＲに引っ張って脱離させるので、例えば、正極ケーブル端子本体２１（負極ケーブル端子本体３１）の嵌合部２１Ａｍ，３１Ａｍおよび外部接続端子１５の金属端子１５Ｘ，１５Ｙの一方あるいは両方をこじるなどして変形させてしまう不具合の発生を防止できる。   As described above, in the assembled battery structure 1 of the present embodiment, the positive cable terminal 23 and the negative cable terminal 33 include the pull tabs 22 and 32, respectively. For this reason, fingers are engaged with the finger engaging portions 22S and 32S of the pull tabs 22 and 32, the pull tabs 22 and 32 are pulled in the detaching direction DR, and the positive electrode cable terminal 23 (negative electrode cable terminal 33) is connected to the assembled battery 10. Can be easily detached from the external connection terminal 15. Further, when detaching the positive cable terminal 23 (negative cable terminal 33), the finger engaging portions of the pull tabs 22 and 32 are pulled and detached in the detaching direction DR. For example, the positive cable terminal main body 21 (negative cable) It is possible to prevent the occurrence of a problem in which one or both of the fitting portions 21Am, 31Am of the terminal body 31) and the metal terminals 15X, 15Y of the external connection terminal 15 are deformed.

その他、本実施形態の組電池構造体１は、外部接続端子１５は壁部１５Ｗの内壁面１５Ｗｂを有する。このため、正極金属端子１５Ｘと負極金属端子１５Ｙを含む外部接続端子１５に対する、ケーブル端子２３，３３および電線２４，３４の接続時の姿勢を一定に規定できる。例えば、外部接続端子１５の表面に沿う沿面放電が懸念される場合でも、内壁面１５Ｗｂを設けたことにより、沿面距離を長く取ることができ、この外部接続端子１５における沿面放電の発生を抑制することができる。   In addition, in the assembled battery structure 1 of the present embodiment, the external connection terminal 15 has an inner wall surface 15Wb of the wall portion 15W. For this reason, the attitude | position at the time of connection of the cable terminals 23 and 33 and the electric wires 24 and 34 with respect to the external connection terminal 15 containing the positive electrode metal terminal 15X and the negative electrode metal terminal 15Y can be prescribed | regulated. For example, even when creeping discharge along the surface of the external connection terminal 15 is concerned, by providing the inner wall surface 15Wb, it is possible to increase the creeping distance and suppress the occurrence of creeping discharge at the external connection terminal 15. be able to.

さらに、本実施形態の組電池構造体１で、プルタブ２２，３２は手指係合部２２Ｓ，３２Ｓを有する。この手指係合部２２Ｓ，３２Ｓは、壁部１５Ｗの内壁面１５Ｗｂよりも脱離方向ＤＲに位置させ得るので、これに手指等を係合させて、脱離方向ＤＲにプルタブ２２，３２を移動させることができる。従って、ケーブル端子２３，３３を外部接続端子１５から容易に脱離させることができる。   Further, in the assembled battery structure 1 of the present embodiment, the pull tabs 22 and 32 have finger engagement portions 22S and 32S. Since the finger engaging portions 22S and 32S can be positioned in the detaching direction DR with respect to the inner wall surface 15Wb of the wall portion 15W, the pull tabs 22 and 32 are moved in the detaching direction DR by engaging fingers or the like with this. Can be made. Accordingly, the cable terminals 23 and 33 can be easily detached from the external connection terminal 15.

しかも、プルタブ２２，３２は、壁面上端１５Ｗｂａおよび上端面２１Ｃａのうち、脱離方向ＤＲに位置する壁面上端１５Ｗｂａよりも低位、つまり、これらよりも脱離方向ＤＲとは逆側に位置させることができる。これにより、手指係合部２２Ｓ，２３Ｓを含め、プルタブ２２，３２全体が、壁面上端１５Ｗｂａおよび上端面２１Ｃａよりも脱離方向ＤＲに突出しないので、このプルタブ２２，３２が、正極ケーブル端子本体２１（負極ケーブル端子本体３１）の脱離方向ＤＲで、他の部材と干渉（接触等）することも防止できる。
なお、ケーブル端子２３，３３を囲む内壁面１５Ｗｂが、ケーブル端子２３，３３の近くに位置しているために、内壁面１５Ｗｂとケーブル端子２３，３３との間に、手指を入れてケーブル端子２３，３３を把持して脱離させがたい本実施形態には、本発明が特に有効である。 Moreover, the pull tabs 22 and 32 are positioned lower than the wall surface upper end 15Wba located in the detaching direction DR among the wall surface upper end 15Wba and the upper end surface 21Ca, that is, on the opposite side to the detaching direction DR. it can. As a result, the entire pull tabs 22 and 32 including the finger engaging portions 22S and 23S do not protrude in the detaching direction DR from the wall surface upper end 15Wba and the upper end surface 21Ca. Interference (contact etc.) with other members can be prevented in the detaching direction DR of the (negative electrode cable terminal body 31).
Since the inner wall surface 15Wb surrounding the cable terminals 23 and 33 is located near the cable terminals 23 and 33, a finger is put between the inner wall surface 15Wb and the cable terminals 23 and 33, and the cable terminal 23 is inserted. The present invention is particularly effective for this embodiment in which it is difficult to grip and detach 33.

なお、ケーブル端子本体２１，３１は電池接続端子本体に、上端面２１Ｃａ，３１Ｃａは端子本体脱離方向側端に、プルタブ２２，３２は脱離補助部材、脱離用係合部に、ケーブル端子２３，３３は電池接続端子に、ケーブル２４，３４は電線に、それぞれ対応している。   The cable terminal main bodies 21 and 31 are the battery connection terminal main body, the upper end surfaces 21Ca and 31Ca are the terminal main body detachment direction side ends, the pull tabs 22 and 32 are the detachment auxiliary members, the detachment engagement portions, and the cable terminals. Reference numerals 23 and 33 correspond to battery connection terminals, and cables 24 and 34 correspond to electric wires.

（変形形態１）
次に、上述した実施形態の第１の変形形態について、図１および図７を参照しつつ説明する。
本変形形態１の組電池構造体１０１は、実施形態におけるプルタブ２２，３２に代えてひも状のプルタブを有する点で上述の実施形態と異なり、それ以外は同様である。
そこで、異なる点を中心に説明し、同様の部分の説明は省略または簡略化する。なお、同様の部分については同様の作用効果を生じる。また、同内容のものには同番号を付して説明する。 (Modification 1)
Next, a first modification of the above-described embodiment will be described with reference to FIGS. 1 and 7.
The assembled battery structure 101 of Modification 1 is different from the above-described embodiment in that it has a string-like pull tab instead of the pull tabs 22 and 32 in the embodiment, and is otherwise the same.
Therefore, different points will be mainly described, and description of similar parts will be omitted or simplified. In addition, about the same part, the same effect is produced. In addition, the same contents are described with the same numbers.

本変形形態にかかる組電池構造体１０１の正極接続ケーブル１２０は、図７（ａ）に示すように、正極端子ケース２１Ｃにその両端部１２２Ｔで固着された正極プルタブ１２２を有する。但し、この正極プルタブ１２２は、合成繊維からなり可撓性のあるひも状である点で実施形態と異なる。   As shown in FIG. 7A, the positive electrode connection cable 120 of the assembled battery structure 101 according to this modification has a positive electrode pull tab 122 fixed to the positive electrode terminal case 21C at both ends 122T. However, this positive electrode pull tab 122 is different from the embodiment in that it is made of a synthetic fiber and has a flexible string shape.

この端部１２２Ｔはいずれも、正極端子ケース２１Ｃの上端面２１Ｃａよりも脱離方向ＤＲとは逆側（図７（ａ）中、下方）に位置している。一方、これら端部１２２Ｔの間に位置する手指係合部１２２Ｓは、手指を係合させてこれを引っ張ることができる部位である。なお、壁部１５Ｗおよび正極ケーブル端子本体２１より脱離方向ＤＲの側で、手指係合部１２２Ｓを手指に係合させると、容易に行うことができる。   All of the end portions 122T are located on the opposite side (downward in FIG. 7A) to the detachment direction DR from the upper end surface 21Ca of the positive electrode terminal case 21C. On the other hand, the finger engaging part 122S located between these end parts 122T is a part which can engage and pull a finger. In addition, it can carry out easily when the finger engagement part 122S is engaged with a finger on the side of the detachment direction DR from the wall 15W and the positive electrode cable terminal main body 21.

一方、正極プルタブ１２２の一部を、例えば正極端子ケース２１Ｃの受け板部２１ＣＭ上に配置すると（図７（ｂ）参照）、ひも状の正極プルタブ１２２は、壁部１５Ｗの壁面上端１５Ｗｂａおよび上端面２１Ｃａよりも低位、つまり、これらよりも脱離方向ＤＲとは逆側に位置する。このため、この正極プルタブ１２２でも、正極ケーブル端子本体２１の脱離方向ＤＲで、他の部材と干渉することを防止できる。
なお、負極接続ケーブル１３０における負極プルタブ１３２についても、正極接続ケーブル１２０と同様の形態を有するので、説明を省略する。 On the other hand, when a part of the positive electrode pull tab 122 is disposed, for example, on the receiving plate portion 21CM of the positive electrode terminal case 21C (see FIG. 7B), the string-like positive electrode pull tab 122 is connected to the wall upper end 15Wba and the upper side of the wall portion 15W. It is positioned lower than the end face 21Ca, that is, on the side opposite to the detaching direction DR. For this reason, even this positive electrode pull tab 122 can prevent interference with other members in the detaching direction DR of the positive electrode cable terminal body 21.
Note that the negative electrode pull tab 132 in the negative electrode connection cable 130 has the same configuration as that of the positive electrode connection cable 120, and thus the description thereof is omitted.

（変形形態２）
次に、実施形態の第２の変形形態について、図１、図８および図９を参照しつつ説明する。
本変形形態２の組電池構造体２０１は、外部接続端子からケーブル端子を脱離させないとき（通常時）に、端子ケースにプルタブを固定可能な形態とされている点で上述の実施形態と異なり、それ以外は同様である。
そこで、異なる点を中心に説明し、同様の部分の説明は省略または簡略化する。なお、同様の部分については同様の作用効果を生じる。また、同内容のものには同番号を付して説明する。 (Modification 2)
Next, a second modification of the embodiment will be described with reference to FIG. 1, FIG. 8, and FIG.
The assembled battery structure 201 of the second modification differs from the above-described embodiment in that the pull tab can be fixed to the terminal case when the cable terminal is not detached from the external connection terminal (normal time). The others are the same.
Therefore, different points will be mainly described, and description of similar parts will be omitted or simplified. In addition, about the same part, the same effect is produced. In addition, the same contents are described with the same numbers.

本変形形態２にかかる組電池構造体２０１の正極接続ケーブル２２０は、実施形態の正極接続ケーブル２０と同様の正極プルタブ２２を有する。但し、正極ケーブル端子本体２２１に、正極プルタブ２２を固定する爪部２２１ＣＮを有する。
具体的には、正極端子ケース２２１Ｃの上面（受け板部２２１ＣＭ上）から薄板状の爪部２２１ＣＮが突出している（図８（ｂ）参照）。この爪部２２１ＣＮの先端部２２１ＣＮａは、正極プルタブ２２の支持部２２Ｔ側に向かって屈曲してなり、この端部２２１ＣＮａと受け板部２２１ＣＭとの間で、正極プルタブ２２（手指係合部２２Ｓ）を固定することができる。つまり、正極プルタブ２２を用いないとき、例えば、正極プルタブ２２を用いて外部接続端子１５から正極ケーブル端子２２３を脱離させないとき、爪部２２１ＣＮに、正極プルタブ２２を係合させ固定しておくことができる（図９参照）。なお、外部接続端子１５から正極ケーブル端子２２３を脱離させるときなど、正極プルタブ２２を用いるときは、爪部２２１ＣＮの端部２２１ＣＮａを正極ケーブル２４の延出方向ＤＡに押して、正極プルタブ２２の固定を解けば良い。
なお、負極接続ケーブル２３０についても、正極接続ケーブル２２０と同様の形態を有するので、説明を省略する。 The positive electrode connection cable 220 of the assembled battery structure 201 according to the second modification has a positive electrode pull tab 22 similar to the positive electrode connection cable 20 of the embodiment. However, the positive electrode cable terminal main body 221 has a claw portion 221CN for fixing the positive electrode pull tab 22.
Specifically, a thin plate-like claw portion 221CN protrudes from the upper surface (on the receiving plate portion 221CM) of the positive electrode terminal case 221C (see FIG. 8B). The tip portion 221CNa of the claw portion 221CN is bent toward the support portion 22T side of the positive electrode pull tab 22, and the positive electrode pull tab 22 (finger engagement portion 22S) is formed between the end portion 221CNa and the receiving plate portion 221CM. Can be fixed. That is, when the positive electrode pull tab 22 is not used, for example, when the positive electrode cable terminal 223 is not detached from the external connection terminal 15 using the positive electrode pull tab 22, the positive electrode pull tab 22 is engaged and fixed to the claw portion 221CN. (See FIG. 9). When the positive electrode pull tab 22 is used, such as when the positive electrode cable terminal 223 is detached from the external connection terminal 15, the end portion 221 CNa of the claw portion 221 CN is pushed in the extending direction DA of the positive electrode cable 24 to fix the positive electrode pull tab 22. To solve.
Note that the negative electrode connection cable 230 has the same form as the positive electrode connection cable 220, and thus the description thereof is omitted.

本変形形態にかかる組電池構造体２０１は、実施形態における作用効果に加えて、外部接続端子１５からケーブル端子２２３，２３３を脱離させないときに、ケーブル端子本体２２１，２３１の爪部２２１ＣＮ，２３１ＣＮで、プルタブ２２，３２を固定できる。これにより、外部からの振動によりプルタブ２２，３２が振動する、またこれによって、プルタブ２２，３２と他の部材とが当たって異音を発生することを抑制できる。   The assembled battery structure 201 according to the present modified embodiment has the claw portions 221CN and 231CN of the cable terminal bodies 221 and 231 when the cable terminals 223 and 233 are not detached from the external connection terminals 15 in addition to the effects in the embodiment. Thus, the pull tabs 22 and 32 can be fixed. Thereby, the pull tabs 22 and 32 are vibrated by vibrations from the outside, and it is possible to suppress the generation of noise due to the pull tabs 22 and 32 hitting other members.

（変形形態３）
次に、実施形態の第３の変形形態について、図１、図１０および図１１を参照しつつ説明する。
本変形形態３の組電池構造体３０１は、これに用いる正極ケーブル端子（負極ケーブル端子）が、脱離方向に突出して固定されたプルタブを備える点、および、外部端子部材が壁部を有さない点で、上述の実施形態と異なり、それ以外は同様である。
そこで、異なる点を中心に説明し、同様の部分の説明は省略または簡略化する。なお、同様の部分については同様の作用効果を生じる。また、同内容のものには同番号を付して説明する。 (Modification 3)
Next, a third modification of the embodiment will be described with reference to FIGS. 1, 10, and 11.
In the assembled battery structure 301 of the third modification, the positive electrode cable terminal (negative electrode cable terminal) used for this has a pull tab fixed to protrude in the detaching direction, and the external terminal member has a wall portion. Unlike the above-described embodiment, the other points are the same.
Therefore, different points will be mainly described, and description of similar parts will be omitted or simplified. In addition, about the same part, the same effect is produced. In addition, the same contents are described with the same numbers.

本変形形態３にかかる組電池構造体３０１の正極接続ケーブル３２０について、図１０（ａ）を参照しつつ説明する。
このうち、正極プルタブ３２２は、実施形態と同様、略コ字状の形態を有し、その両端部に位置する支持部３２２Ｔと、これらの中間に位置し、手指を係合して引っ張るのに用いる係合部３２２Ｓとを有する。但し、正極プルタブ３２２は正極端子ケース３２１Ｃと一体に形成され、２つの支持部３２２Ｔは、正極ケーブル端子本体３２１の上端面３２１Ｃａから延出し、正極プルタブ３２２全体が、正極ケーブル端子本体３２１（上端面３２１Ｃａ）から脱離方向ＤＲに向けて突出してなる。なお、正極プルタブ３２２は固定されているので、実施形態と異なり、正極接続ケーブル３２０は受け板部を持たない。
また、負極接続ケーブル３３０についても、正極接続ケーブル３２０と同様の形態を有するので、説明を省略する。 The positive electrode connection cable 320 of the assembled battery structure 301 according to the third modification will be described with reference to FIG.
Among these, the positive electrode pull tab 322 has a substantially U-shaped form, similar to the embodiment, and is positioned in the middle between the support portions 322T located at both ends thereof, to engage and pull fingers. And an engaging portion 322S to be used. However, the positive electrode pull tab 322 is formed integrally with the positive electrode terminal case 321C, and the two support portions 322T extend from the upper end surface 321Ca of the positive electrode cable terminal main body 321. The entire positive electrode pull tab 322 is connected to the positive electrode cable terminal main body 321 (the upper end surface). 321Ca) protrudes in the detaching direction DR. Since the positive electrode pull tab 322 is fixed, unlike the embodiment, the positive electrode connection cable 320 does not have a receiving plate portion.
Also, the negative electrode connection cable 330 has the same form as the positive electrode connection cable 320, and thus the description thereof is omitted.

図１０（ｂ）に、接続ケーブル３２０，３３０と、これを接続してなる外部接続端子３１５を示す。この外部接続端子３１５は、前述の実施形態と異なり、壁部を持たない。つまり、接続ケーブル３２０，３３０のケーブル端子３２３，３３３は、他の部材に囲まれていない。   FIG. 10B shows the connection cables 320 and 330 and the external connection terminal 315 formed by connecting them. The external connection terminal 315 does not have a wall portion unlike the above-described embodiment. That is, the cable terminals 323 and 333 of the connection cables 320 and 330 are not surrounded by other members.

図１１に、正極接続ケーブル３２０を外部接続端子３１５に接続させた状態における断面図（図１０（ｂ）のＥ−Ｅ断面）を示す。正極接続ケーブル３２０の正極ケーブル端子３２３は、実施形態と同様、その嵌合部２１Ａｍが正極金属端子１５Ｘと嵌合することにより、電気的にも、機械的にも、これと接続している。
なお、接続している負極接続ケーブル３３０についても、正極接続ケーブル３２０と同様にして外部接続端子３１５と接続しているので、説明を省略する。 FIG. 11 shows a cross-sectional view (cross-section EE in FIG. 10B) in a state where the positive electrode connection cable 320 is connected to the external connection terminal 315. Similarly to the embodiment, the positive cable terminal 323 of the positive electrode connection cable 320 is electrically and mechanically connected to the positive electrode metal terminal 15X by fitting the fitting portion 21Am.
Note that the connected negative electrode connection cable 330 is also connected to the external connection terminal 315 in the same manner as the positive electrode connection cable 320, and thus the description thereof is omitted.

以上で説明したように、本変形形態３の組電池構造体３０１では、正極ケーブル端子３２３および負極ケーブル端子３３３は、それぞれプルタブ３２２，３３２を備えている。このため、これらプルタブ３２２，３３２に手指を係合させて、正極ケーブル端子３２３（負極ケーブル端子３３３）を組電池１０の外部接続端子３１５から容易に脱離させることができる。また、正極ケーブル端子３２３（負極ケーブル端子３３３）を脱離させる際、例えば、正極ケーブル端子本体３２１（負極ケーブル端子本体３３１）の嵌合部２１Ａｍ，３１Ａｍおよび外部接続端子３１５の金属端子１５Ｘ，１５Ｙの一方あるいは両方をこじるなどして変形させてしまう不具合の発生を防止して、正極ケーブル端子３２３（負極ケーブル端子３３３）を適切に外部接続端子３１５から脱離させることができる。   As described above, in the assembled battery structure 301 of the third modification, the positive cable terminal 323 and the negative cable terminal 333 include the pull tabs 322 and 332, respectively. Therefore, the positive cable terminal 323 (the negative cable terminal 333) can be easily detached from the external connection terminal 315 of the assembled battery 10 by engaging the fingers with the pull tabs 322 and 332. Further, when the positive cable terminal 323 (negative cable terminal 333) is detached, for example, the fitting portions 21Am and 31Am of the positive cable terminal body 321 (negative cable terminal body 331) and the metal terminals 15X and 15Y of the external connection terminal 315 are used. Therefore, the positive cable terminal 323 (the negative cable terminal 333) can be appropriately detached from the external connection terminal 315 by preventing the occurrence of a problem that deforms one or both of them.
