端子接続部品および電池モジュールTerminal connection parts and battery module
　本発明は、端子接続部品および電池モジュールに関する。 The present invention relates to a terminal connection component and a battery module.
　例えば電気自動車やハイブリッドカー等では、動力源等として、単電池を複数接続してなる電池モジュールを、複数接続して用いることがある。
　複数の単電池あるいは複数の電池モジュールを接続する場合、例えば特許文献１に記載されているように、バスバー等の接続部材を隣り合う単電池のボルト状の端子間に配置して、端子にナットを締め付けることにより接続する。 For example, in an electric vehicle, a hybrid car, or the like, a plurality of battery modules formed by connecting a plurality of single cells may be used as a power source.

　しかしながら、ボルト締結により端子間を接続する場合、端子ごとにボルト締結を行う必要があるので手間がかかり、作業効率が悪いという問題があった。また、ボルト締結により端子間を接続する場合には、トルク管理が行われるためボルト位置の不良等を防止できないという問題があった。 However, when connecting terminals by bolt fastening, there is a problem that it is necessary to perform bolt fastening for each terminal, so that it takes time and work efficiency is poor. In addition, when connecting terminals by bolt fastening, there is a problem that torque management is performed, so that a defect in the bolt position cannot be prevented.
　本発明は上記のような事情に基づいて完成されたものであって、端子間接続作業の作業効率を向上することを目的とする。 The present invention has been completed based on the above circumstances, and an object thereof is to improve the work efficiency of the inter-terminal connection work.
　上記課題を解決するものとして本発明は、第１端子と第２端子とを接続する端子接続部品であって、前記第１端子に対して回転規制される規制部材と、前記第１端子及び前記第２端子を貫通する軸部を有し、前記軸部を回転させることで前記第１端子及び前記第２端子を押圧する押圧部により、前記第１端子及び前記第２端子に荷重がかかる位置に回転可能に保持される回転部材と、を備える端子接続部品である。 In order to solve the above problems, the present invention provides a terminal connection part for connecting a first terminal and a second terminal, a restriction member that is restricted from rotating with respect to the first terminal, the first terminal, and the A position where a load is applied to the first terminal and the second terminal by a pressing portion that presses the first terminal and the second terminal by rotating the shaft portion by having a shaft portion penetrating the second terminal. And a rotating member that is rotatably held by the terminal connecting component.
　本発明において、第１端子と第２端子とを接続するときには、例えば、回転部材の軸部に第１端子および第２端子を貫通させ、軸部を回転させる。軸部を回転させて、押圧部が規制部材とともに第１端子および第２端子を押圧し、第１端子及び第２端子に荷重がかかる位置に至ると、その位置で回転部材が保持される。第１端子および第２端子に荷重がかかると２つの端子は電気的に接続可能な状態となる。 In the present invention, when connecting the first terminal and the second terminal, for example, the first terminal and the second terminal are passed through the shaft portion of the rotating member, and the shaft portion is rotated. When the shaft portion is rotated so that the pressing portion presses the first terminal and the second terminal together with the regulating member, and the load is applied to the first terminal and the second terminal, the rotating member is held at that position. When a load is applied to the first terminal and the second terminal, the two terminals become electrically connectable.
　つまり、本発明によれば、回転部材に第１端子および第２端子を貫通させて、軸部を２つの端子に荷重がかかった状態となるように回転させればよいので、端子間の接続にボルト締結が不要であり、端子間接続作業の作業効率が向上する。 That is, according to the present invention, the first terminal and the second terminal can be passed through the rotating member, and the shaft portion can be rotated so that the load is applied to the two terminals. Bolt fastening is unnecessary, and the work efficiency of inter-terminal connection work is improved.
　本発明は以下の構成としてもよい。
　前記押圧部と、前記第１端子または前記第２端子との間に挟持されたバネ部材を備えていてもよい。このような構成とすると端子の板厚方向における公差を吸収することができる。 The present invention may have the following configurations.
You may provide the spring member clamped between the said press part and the said 1st terminal or the said 2nd terminal. With such a configuration, tolerances in the thickness direction of the terminals can be absorbed.
　前記第１端子は、単電池に設けられた電極端子であってもよい。
　このような構成とすると、単電池を複数接続して電池モジュールを構成するときや複数の電池モジュールを接続する際の接続作業の作業効率が向上する。 The first terminal may be an electrode terminal provided in the unit cell.
With such a configuration, the work efficiency of the connection work when connecting a plurality of single cells to form a battery module or connecting a plurality of battery modules is improved.
　また、本発明は、単電池と、上記端子接続部品と、を備えた電池モジュールであって、前記第１端子は、前記単電池に設けられた電極端子であって、前記第２端子との接続部が前記単電池の前記電極端子が設けられている端子形成面と対向するように配され、前記回転部材は、前記押圧部を前記第１端子と前記単電池の端子形成面との間に配しつつ、前記軸部に前記第１端子を貫通させた状態で、前記単電池に組み込まれている電池モジュールであってもよい。 Moreover, this invention is a battery module provided with the cell and the said terminal connection component, Comprising: The said 1st terminal is an electrode terminal provided in the said cell, Comprising: With the said 2nd terminal, The connecting portion is disposed so as to face the terminal forming surface on which the electrode terminal of the unit cell is provided, and the rotating member has the pressing portion between the first terminal and the terminal forming surface of the unit cell. It may be a battery module incorporated in the unit cell with the first terminal penetrating through the shaft portion.
　このような構成とすると、単電池の電極端子の第２端子との接続部が単電池の端子形成面と対向するように配されるとともに、回転部材の押圧部が、単電池の端子形成面との間に配されているので、端子接続部品の低背化を図ることができる。また、上記構成において、単電池に組み込まれている回転部材の軸部には第１端子（電極端子）が貫通されており、第２端子および規制部材を軸部の延びる方向から組み付けていけばよいので組み付け作業を簡素化することができる。 With such a configuration, the connection portion of the unit cell electrode terminal with the second terminal is arranged so as to oppose the unit cell terminal formation surface, and the rotating member pressing portion is the unit cell terminal formation surface. Therefore, it is possible to reduce the height of the terminal connection parts. Further, in the above configuration, the first terminal (electrode terminal) is passed through the shaft portion of the rotating member incorporated in the unit cell, and the second terminal and the regulating member are assembled from the direction in which the shaft portion extends.

When the rotation pin 33 is inserted into the pin insertion hole 31A of the shaft portion 31 and the rotation pin 33 is attached to the shaft portion 31, the state shown in FIG.
　回転部材３０および規制部材２６を取り付けた電極端子１２の上側から第１ハウジング２０を取り付ける。第１ハウジング２０の係止爪２１をセパレータ１５のハウジング固定孔１６に対応させて上方から第１ハウジング２０をセパレータ１５に取り付けると、第１ハウジング２０の係止爪２１がセパレータ１５のハウジング固定孔１６に係止されて固定される（図５を参照）。 The first housing 20 is attached from the upper side of the electrode terminal 12 to which the rotating member 30 and the regulating member 26 are attached. When the locking claw 21 of the first housing 20 is made to correspond to the housing fixing hole 16 of the separator 15 and the first housing 20 is attached to the separator 15 from above, the locking claw 21 of the first housing 20 becomes the housing fixing hole of the separator 15. 16 and fixed (see FIG. 5).
　第１ハウジング２０の取付作業と同時又は前後して、以下に説明する手順で第２ハウジング４０に第２端子５０とシャッター６０を取り付ける作業を行う。 At the same time as or before or after the mounting operation of the first housing 20, the operation of mounting the second terminal 50 and the shutter 60 on the second housing 40 is performed according to the procedure described below.
　まず、第２端子５０の幅狭領域５３に電線５５を接合する。具体的には、電線５５の両端末において絶縁被覆５７を剥離除去して、芯線５６を露出させておき、電線５５の両端末で露出する露出芯線５６にそれぞれ第２端子５０を接合する（図１０を参照）。露出芯線５６と第２端子５０の接合は、各種溶接法等、公知の接合方法により行われる。 First, the electric wire 55 is joined to the narrow region 53 of the second terminal 50. Specifically, the insulation coating 57 is peeled and removed at both ends of the electric wire 55 to expose the core wire 56, and the second terminals 50 are joined to the exposed core wires 56 exposed at both ends of the electric wire 55 (FIG. 10). The exposed core wire 56 and the second terminal 50 are joined by a known joining method such as various welding methods.
　次に、電線５５が第２ハウジング４０の蓋部４７の切欠部４７Ｂから外側に配されるように第２端子５０を配して、第２端子５０の上端部を蓋部４７の端子保持部４７Ｃに嵌めこんで保持させる。第２端子５０を保持させた蓋部４７を第２ハウジング４０の本体部４１に取り付ける。このとき第２端子５０の電線５５が本体部４１の切欠部４１Ａから外側に配されるように蓋部４７を配置する。蓋部４７を本体部４１に取り付けると蓋部４７が本体部４１の蓋係止孔４２Ａに係止され、電線５５が電線配置孔４８から外側に配される。また、第２端子５０の係止凸部５２が第２ハウジング４０の本体部４１内の端子係止部４４より係止され第２端子５０が本体部４１によっても保持される。 Next, the second terminal 50 is arranged so that the electric wire 55 is arranged on the outside from the notch 47 </ b> B of the lid portion 47 of the second housing 40, and the upper end portion of the second terminal 50 is connected to the terminal holding portion of the lid portion 47. Fit into 47C and hold. The lid 47 holding the second terminal 50 is attached to the main body 41 of the second housing 40. At this time, the lid portion 47 is arranged so that the electric wire 55 of the second terminal 50 is arranged outside from the cutout portion 41 </ b> A of the main body portion 41. When the lid portion 47 is attached to the main body portion 41, the lid portion 47 is locked in the lid locking hole 42 </ b> A of the main body portion 41, and the electric wire 55 is arranged outside from the electric wire arrangement hole 48. Further, the locking projection 52 of the second terminal 50 is locked by the terminal locking portion 44 in the main body 41 of the second housing 40, and the second terminal 50 is also held by the main body 41.
　第２端子５０を保持させた第２ハウジング４０の蓋部４７のシャッター配置孔４９に、上側からシャッター６０を差し込むと、第２ハウジング４０の本体部４１の内壁に設けた係止凹部４５に、ハウジング係止突部６２が係止され、シャッター６０の上端部が蓋部４７の上方からはみ出した状態で保持される。このようにして図５に示すような第２端子５０およびシャッター６０を取り付けた第２ハウジング４０が得られる。 When the shutter 60 is inserted into the shutter placement hole 49 of the lid portion 47 of the second housing 40 holding the second terminal 50 from above, the locking recess 45 provided on the inner wall of the main body portion 41 of the second housing 40 The housing locking projection 62 is locked, and the upper end of the shutter 60 is held in a state of protruding from the upper side of the lid 47. In this way, the second housing 40 to which the second terminal 50 and the shutter 60 are attached as shown in FIG. 5 is obtained.
　第２端子５０およびシャッター６０を取り付けた第２ハウジング４０を、図５に示すように、電極端子１２等を収容した第１ハウジング２０に嵌合させる。開口部を下側に向けた状態とした第２ハウジング４０を、第１ハウジング２０に上方から嵌合させる。第２ハウジング４０を下方に移動させて、第２端子５０の下端部が第１ハウジング２０の端子挿入口２２に至ると、第２端子５０が端子挿入口２２に挿入されて第２端子５０の溝部５１が回転部材３０の軸部３１に案内される。 The second housing 40 to which the second terminal 50 and the shutter 60 are attached is fitted into the first housing 20 in which the electrode terminals 12 and the like are accommodated, as shown in FIG. The second housing 40 with the opening directed downward is fitted into the first housing 20 from above. When the second housing 40 is moved downward and the lower end portion of the second terminal 50 reaches the terminal insertion port 22 of the first housing 20, the second terminal 50 is inserted into the terminal insertion port 22 and the second terminal 50. The groove portion 51 is guided to the shaft portion 31 of the rotating member 30.
　第２ハウジング４０をさらに下方に移動させて第１ハウジング２０との嵌合位置にまで至ると、図６に示すように、第２ハウジング４０の側壁の係止突部４３が第１ハウジング２０の側壁のハウジング係止孔２５に嵌り込んで第２ハウジング４０が第１ハウジング２０に係止される。また、第２ハウジング４０の治具挿入口４６と第１ハウジング２０の治具挿入口２４とが重なり合って１つの治具挿入口となる。 When the second housing 40 is further moved downward to reach the fitting position with the first housing 20, as shown in FIG. 6, the locking projections 43 on the side walls of the second housing 40 are formed on the first housing 20. The second housing 40 is locked to the first housing 20 by fitting into the housing locking hole 25 on the side wall. In addition, the jig insertion port 46 of the second housing 40 and the jig insertion port 24 of the first housing 20 overlap to form one jig insertion port.
　この状態において、第２端子５０の溝部５１に回転部材３０の軸部３１が配され、第２端子５０は電極端子１２と規制部材２６との間に挟まれる（図７および図８を参照）るが、シャッター６０の一部は第２ハウジング４０の蓋部４７の上方からはみ出したままである。 In this state, the shaft portion 31 of the rotating member 30 is disposed in the groove portion 51 of the second terminal 50, and the second terminal 50 is sandwiched between the electrode terminal 12 and the regulating member 26 (see FIGS. 7 and 8). However, a part of the shutter 60 still protrudes from above the lid portion 47 of the second housing 40.
　次に、図９に示すように第２ハウジング４０の治具挿入口４６から治具を挿入して回転ピン３３を回動させる。回動させる前の回転ピン３３は上下方向を向いている（図１０の右側の端子接続部品１０および図１２を参照）。回転ピン３３が上下方向を向いているときには、図１２に示すように、シャッター６０の規制リブ６３と回転ピン３３とが当接しておりシャッター６０の下方への移動が規制されている。 Next, as shown in FIG. 9, a jig is inserted from the jig insertion port 46 of the second housing 40 to rotate the rotary pin 33. The rotating pin 33 before rotating is directed in the vertical direction (see the terminal connection component 10 on the right side of FIG. 10 and FIG. 12). When the rotating pin 33 faces in the up-down direction, as shown in FIG. 12, the regulating rib 63 of the shutter 60 and the rotating pin 33 are in contact with each other, and the downward movement of the shutter 60 is regulated.
　治具６４を操作して回転ピン３３が横方向を向いている状態から回動させると、シャッター６０と回転ピン３３との当接状態が解除されて、回転ピン３３とシャッター６０とが非当接状態となる（図１３を参照）。本実施形態では回転ピン３３を９０°回動させた状態のときにも、シャッター６０が治具６４と当接しているので、下方への移動が規制されているが、電極端子１２および第２端子５０は皿バネ３５を介して押圧部３２により押圧され相互に接触し荷重のかかった状態（電気的な接続可能な状態）となる。次いで、治具６４を抜くと、治具６４とシャッター６０との当接状態が解除されるので、治具６４を抜くだけでシャッター６０が下方に移動して治具挿入口２４，４６が閉じた状態となる（図３を参照）。 When the jig 64 is operated to rotate the rotating pin 33 from the horizontal direction, the contact state between the shutter 60 and the rotating pin 33 is released, and the rotating pin 33 and the shutter 60 are not applied. The contact state is established (see FIG. 13). In the present embodiment, the shutter 60 is in contact with the jig 64 even when the rotary pin 33 is rotated by 90 °, so that the downward movement is restricted, but the electrode terminal 12 and the second The terminals 50 are pressed by the pressing portion 32 via the disc spring 35 and come into contact with each other and are in a state where a load is applied (a state where electrical connection is possible). Next, when the jig 64 is removed, the contact state between the jig 64 and the shutter 60 is released. Therefore, the shutter 60 moves downward by simply removing the jig 64 and the jig insertion ports 24 and 46 are closed. (See FIG. 3).
　同様の作業を繰り返し全ての回転ピン３３を回動させる操作および治具６４の抜き取り作業が終了すると、端子接続部品１０の取り付け作業ならびに単電池１１の接続作業が終了する。 When the same operation is repeated and the operation of rotating all the rotation pins 33 and the extraction operation of the jig 64 are completed, the installation operation of the terminal connection component 10 and the connection operation of the unit cells 11 are completed.
　（本実施形態の作用および効果）
　本実施形態によれば、回転部材３０に電極端子１２および第２端子５０を貫通させて、軸部３１を２つの端子１２，５０に荷重がかかった状態となるように回転させればよいので、端子１２，５０間の接続にボルト締結が不要であり、端子間接続作業の作業効率が向上する。 (Operation and effect of this embodiment)
According to the present embodiment, the electrode terminal 12 and the second terminal 50 may be passed through the rotating member 30 and the shaft portion 31 may be rotated so that a load is applied to the two terminals 12 and 50. The bolt fastening is unnecessary for the connection between the terminals 12 and 50, and the work efficiency of the inter-terminal connection work is improved.
　また、本実施形態によれば、押圧部３２と、電極端子１２との間に挟持された皿バネ３５を備えているから、端子１２，５０の板厚方向における公差を吸収することができる。 In addition, according to the present embodiment, since the disc spring 35 sandwiched between the pressing portion 32 and the electrode terminal 12 is provided, the tolerance in the plate thickness direction of the terminals 12 and 50 can be absorbed.
　また、本実施形態によれば、第１端子１２は、単電池１１に設けられた電極端子１２であるから、単電池１１を複数接続して電池モジュールを構成するときや複数の電池モジュールを接続する際の接続作業の作業効率が向上する。 Moreover, according to this embodiment, since the 1st terminal 12 is the electrode terminal 12 provided in the single battery 11, when connecting the multiple single battery 11 and comprising a battery module, or connecting several battery modules. The work efficiency of the connection work when doing is improved.
　また、本実施形態によれば、回転部材３０の回動操作を治具６４により行うようになっているので、端子１２，５０に直接指が触れることがなく安全性が高い。 Further, according to the present embodiment, since the rotation operation of the rotating member 30 is performed by the jig 64, the finger is not directly touched to the terminals 12 and 50, and the safety is high.
　さらに本実施形態によれば、回転ピン３３の回動操作により、電極端子１２と第２端子５０との接続作業を行うとともに、電極端子１２と第２端子５０との接続部分をシャッター６０により閉じる作業を行うことができるので、作業効率に優れる。 Furthermore, according to the present embodiment, the connecting operation between the electrode terminal 12 and the second terminal 50 is performed by rotating the rotating pin 33, and the connecting portion between the electrode terminal 12 and the second terminal 50 is closed by the shutter 60. Since work can be performed, work efficiency is excellent.
　＜実施形態２＞
　本発明に係る実施形態２の端子接続部品７０を図１４ないし図２４によって説明する。以下の説明において図１４における上方を上とし下方を下とする。図１４においては電池ケース１４の一部を示しているが、他の図では、単電池１１に関してセパレータ１５よりも上の部分のみを描いている。 <Embodiment 2>
A terminal connection component 70 according to a second embodiment of the present invention will be described with reference to FIGS. In the following description, the upper side in FIG. In FIG. 14, a part of the battery case 14 is shown, but in the other figures, only the part above the separator 15 with respect to the unit cell 11 is drawn.
　本実施形態の端子接続部品７０は、回転部材７１の回転ピン７２が図２１における左右方向（横方向）を向いているときにシャッター７３が開いており、回転ピン７２が上下方向（縦方向）を向いているときにシャッター７３が閉じるという点で実施形態１とは相違する。実施形態１と同様の構成については同じ符号を付し、重複した説明は省略する。 In the terminal connection component 70 of the present embodiment, the shutter 73 is opened when the rotation pin 72 of the rotation member 71 faces in the left-right direction (lateral direction) in FIG. 21, and the rotation pin 72 is in the vertical direction (vertical direction). This is different from the first embodiment in that the shutter 73 is closed when facing the screen. The same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
　本実施形態において、回転ピン７２が左右方向（横方向）を向いているとき（図１６～図２０、図２３）よりも、上下方向（縦方向）を向いているとき（図１５および図２４）に、２つの端子にかかる荷重が大きくなっている。 In the present embodiment, when the rotating pin 72 is oriented in the vertical direction (vertical direction) rather than when the rotational pin 72 is oriented in the horizontal direction (lateral direction) (FIGS. 16 to 20, FIG. 23). ), The load applied to the two terminals is large.
　第２ハウジング４０の治具通し孔４６と第１ハウジング２０の治具通し孔２４を閉じる樹脂製のシャッター７３は、略中央にＵ字状のスリット６１が形成されており、スリット６１の内側にハウジング係止突部６２が形成されている点では実施形態１と同様である。しかしながら本実施形態では、図２１に示すように、シャッター７３の下端部には、回転部材７１の回動操作を妨げないように半円状の切欠部７３Ａが形成されており、かつ、シャッター７３の背面側の面には、円弧状の規制リブ７４が回転ピン７２が上下方向（縦方向）に配されるときに干渉しないように形成されている。 A resin-made shutter 73 that closes the jig through hole 46 of the second housing 40 and the jig through hole 24 of the first housing 20 has a U-shaped slit 61 formed at a substantially central portion. It is the same as that of the first embodiment in that the housing locking projection 62 is formed. However, in the present embodiment, as shown in FIG. 21, a semicircular cutout portion 73 </ b> A is formed at the lower end portion of the shutter 73 so as not to hinder the rotation operation of the rotating member 71, and the shutter 73. An arc-shaped regulating rib 74 is formed on the rear side surface of the motor so as not to interfere when the rotary pin 72 is arranged in the vertical direction (vertical direction).
　本実施形態の端子接続部品７０の接続方法について説明する。本実施形態では回転ピン７２を、初期位置（左右方向を向いている位置、図２１の右側の端子接続部品７０の回転ピン７２の位置）から例えば右回りに少し回動させると、回転ピン７２の左端部は引き続き規制リブ７４と干渉するが、回転ピン７２の右端部は規制リブ７４と干渉しない位置に配される。一方、電極端子１２および第２端子５０にかかる荷重については徐々に大きくなり６０°回動させたところで最大となる（図２５を参照）。 The connection method of the terminal connection component 70 of this embodiment will be described. In the present embodiment, when the rotation pin 72 is slightly rotated clockwise, for example, from the initial position (position facing the left-right direction, position of the rotation pin 72 of the right terminal connection component 70 in FIG. 21), the rotation pin 72 is rotated. The left end portion of the rotating pin 72 continues to interfere with the restricting rib 74, but the right end portion of the rotating pin 72 is disposed at a position where it does not interfere with the restricting rib 74. On the other hand, the load applied to the electrode terminal 12 and the second terminal 50 gradually increases and becomes the maximum when rotated by 60 ° (see FIG. 25).
　回転ピン７２を初期位置から約９０°回動させて、回転ピン７２が規制リブ７４と当接しない位置（干渉しない位置）に配されると、シャッター７３が下方へ移動可能となる（図２２を参照）。回転ピン７２とシャッター７３とが非当接状態となっても、治具６４がハウジング２０，４０内に配されているときには、シャッター７３が治具６４と当接しているので、下方への移動が規制されている。 When the rotation pin 72 is rotated about 90 ° from the initial position and is disposed at a position where the rotation pin 72 does not contact the restriction rib 74 (a position where the rotation pin 72 does not interfere), the shutter 73 can be moved downward (FIG. 22). See). Even when the rotary pin 72 and the shutter 73 are not in contact with each other, when the jig 64 is disposed in the housings 20 and 40, the shutter 73 is in contact with the jig 64, and therefore the movement downward. Is regulated.
　このとき、電極端子１２および第２端子５０は、皿バネ３５を介して押圧部３２により押圧され相互に接触し荷重のかかった状態（電気的な接続可能な状態）である。この状態において電極端子１２および第２端子５０に係る荷重は、回転ピン７２を初期位置から６０°回動したときよりもやや小さくなるが、回転ピン７２が初期位置にあるときより大きい（図２５を参照）。図２５中、「初期状態」とは回転ピン７２が初期位置にある状態のことをいい、「最大荷重時」とは、電極端子１２および第２端子５０にかかる荷重が最大のときをいい、「終了状態」とは、初期位置から９０°回動させた状態をいい、「Ｘ」とは端子が押される力（押圧力）を示す。 At this time, the electrode terminal 12 and the second terminal 50 are pressed by the pressing portion 32 via the disc spring 35 and are in contact with each other and loaded (electrically connectable state). In this state, the load applied to the electrode terminal 12 and the second terminal 50 is slightly smaller than when the rotating pin 72 is rotated by 60 ° from the initial position, but is larger than when the rotating pin 72 is in the initial position (FIG. 25). See). In FIG. 25, “initial state” means a state in which the rotating pin 72 is in the initial position, and “at the time of maximum load” means that the load applied to the electrode terminal 12 and the second terminal 50 is maximum, The “finished state” means a state rotated by 90 ° from the initial position, and “X” indicates a force (pressing force) for pressing the terminal.
　次に、治具通し孔２４，４６から治具６４を抜き取ると、治具６４とシャッター７３との当接状態が解除され、シャッター７３が下方に移動して治具通し孔２４，４６が閉じた状態となる（図１５を参照）。 Next, when the jig 64 is removed from the jig through holes 24 and 46, the contact state between the jig 64 and the shutter 73 is released, the shutter 73 moves downward, and the jig through holes 24 and 46 are closed. (See FIG. 15).
　同様の作業を繰り返し全ての回転ピン７２を回動させる操作および治具６４抜き取り作業が終了すると、端子接続部品７０の取り付け作業ならびに単電池１１の接続作業が終了する。上記以外の構成については実施形態１と概ね同様である。 When the same operation is repeated and the operation of rotating all the rotating pins 72 and the operation of extracting the jig 64 are completed, the installation work of the terminal connection component 70 and the connection work of the unit cells 11 are completed. The configuration other than the above is substantially the same as that of the first embodiment.
　本実施形態によれば、実施形態１と同様の効果に加えて、以下の効果がある。本実施形態では回転ピン７２が上下方向を向いている状態のとき（初期位置から９０°回動させたとき）のみシャッター７３が下方へ移動可能となる。その結果、本実施形態によれば、２つの端子１２，５０に確実な接続状態となるような荷重がかかったときのみシャッター７３が下降するように設定することができるので、端子１２，５０間が接続されているか否かについてのチェックを容易に行うことができる。 According to this embodiment, in addition to the same effects as those of the first embodiment, the following effects can be obtained. In the present embodiment, the shutter 73 can be moved downward only when the rotation pin 72 is oriented in the vertical direction (when rotated by 90 ° from the initial position). As a result, according to the present embodiment, the shutter 73 can be set to be lowered only when a load is applied so that the two terminals 12 and 50 are reliably connected. It is possible to easily check whether or not is connected.

A disk-shaped portion of the electrode terminal 112 that is disposed substantially parallel to the terminal formation surface 114 </ b> A (an example of “facing”) is a connection portion 113 connected to the second terminal 140. A shaft portion insertion hole 113A through which the shaft portion 131 of the rotating member 130 is inserted is formed in the connection portion 113 of the electrode terminal 112 (see FIG. 29).

Hereinafter, a connection method of the terminal connection component 100 of the present embodiment will be described.
While the pressing portion 132 and the disc spring 135 are arranged between the electrode terminal 112 and the terminal forming surface 114A of the single battery 111, the rotating member 130 incorporated is inserted in the state where the electrode terminal 112 is passed through the shaft portion 131. A single battery 111 is prepared. A desired number of unit cells 111 are arranged so that the electrode terminals 112 of adjacent unit cells 111 have opposite polarities, and the housing 120 is attached to the terminal formation surface 114A (the upper surface in the present embodiment) of each unit cell 111. Specifically, when the locking projection 121 of the housing 120 is locked in the locking hole 115 of the battery case 114, the housing 120 is attached to the terminal forming surface 114 </ b> A of the unit cell 111.
　次に、規制部材１２７の貫通孔１２７Ａを回転部材１３０の軸部１３１に貫通させることにより規制部材１２７を回転部材１３０に取り付けると規制部材１２７は電極端子１１２に対して回転規制される。回転が規制されている状態の回転部材１３０のピン挿通孔１３１Ａに回転ピン１３３を挿通させる。このとき、回転ピン１３３の位置を、図３７および図３８に示すように規制部材１２７の厚み寸法が最大になっている位置（図３７における左右方向）からずらしておく。 Next, when the restricting member 127 is attached to the rotating member 130 by passing the through hole 127A of the restricting member 127 through the shaft portion 131 of the rotating member 130, the restricting member 127 is restricted from rotating with respect to the electrode terminal 112. The rotation pin 133 is inserted into the pin insertion hole 131A of the rotation member 130 in a state where the rotation is restricted. At this time, the position of the rotating pin 133 is shifted from the position (the left-right direction in FIG. 37) where the thickness dimension of the restricting member 127 is maximized as shown in FIGS.
　回転ピン１３３を図３７および図３８に示す状態にしておいて、次に、収容突部１２２の開口から第２端子１４０を取り付ける。具体的には、規制部材１２７の取付突部１２８に第２端子１４０の端子接続部１４２の溝部１４１を配して規制部材１２７と電極端子１１２との間に端子接続部１４２を差し込むと、図３９および図４０に示すように、第２端子１４０が規制部材１２７に取り付けられる。このとき、回転ピン１３３の位置は規制部材１２７の厚みが最大の部分の位置ではないので、第２端子１４０と電極端子１１２とは、図４０に示すように、接触しているが、電気的な接続が可能な程度の荷重はかかっていない。ここで、図３２、図３５、図３９および図４０においては、電極端子１１２と第２端子１４０との接続状態を示すため、ハウジング１２０を省略している。 With the rotating pin 133 in the state shown in FIGS. 37 and 38, the second terminal 140 is attached from the opening of the housing projection 122. Specifically, when the groove portion 141 of the terminal connection portion 142 of the second terminal 140 is arranged on the mounting protrusion 128 of the restriction member 127 and the terminal connection portion 142 is inserted between the restriction member 127 and the electrode terminal 112, FIG. As shown in FIG. 39 and FIG. 40, the second terminal 140 is attached to the restricting member 127. At this time, since the position of the rotating pin 133 is not the position of the portion where the thickness of the regulating member 127 is the maximum, the second terminal 140 and the electrode terminal 112 are in contact as shown in FIG. There is no load to the extent that secure connection is possible. Here, in FIGS. 32, 35, 39, and 40, the housing 120 is omitted to show the connection state between the electrode terminal 112 and the second terminal 140.
　次に、治具（図示せず）を用いて回転ピン１３３を図３１に示す位置まで回動させる。すると、電極端子１１２および第２端子１４０は皿バネ１３５を介して押圧部１３２により押圧され相互に接触し荷重のかかった状態（電気的な接続が可能な状態）となる。 Next, the rotating pin 133 is rotated to the position shown in FIG. 31 using a jig (not shown). Then, the electrode terminal 112 and the second terminal 140 are pressed by the pressing portion 132 via the disc spring 135 and come into contact with each other and are in a state where a load is applied (a state where electrical connection is possible).
　次に収容突部１２２の上側の開口にハウジングカバー１２４を被せ付ける。具体的には、ハウジングカバー１２４のピン固定部１２６を回転ピン１３３の上方に配して、ハウジング１２０のカバー係止部１２３をハウジングカバー１２４の係止受け部１２５に係合させる。これにより、ハウジングカバー１２４のピン固定部１２６により回転ピン１３３が移動を規制されるとともに、ハウジングカバー１２４がハウジング１２０に係止される。 Next, the housing cover 124 is put on the upper opening of the housing projection 122. Specifically, the pin fixing portion 126 of the housing cover 124 is disposed above the rotation pin 133, and the cover locking portion 123 of the housing 120 is engaged with the locking receiving portion 125 of the housing cover 124. Accordingly, the movement of the rotation pin 133 is restricted by the pin fixing portion 126 of the housing cover 124, and the housing cover 124 is locked to the housing 120.
　同様の作業を繰り返し全ての回転ピン１３３を回動させる操作およびハウジングカバー１２４の取り付け作業が終了すると、端子接続部品１００の取り付け作業ならびに単電池１１１の接続作業が終了する。 When the same operation is repeated and the operation of rotating all the rotating pins 133 and the mounting operation of the housing cover 124 are completed, the mounting operation of the terminal connection component 100 and the connecting operation of the unit cells 111 are completed.
　（本実施形態の作用および効果）
　本実施形態によれば、実施形態１と同様に、回転部材１３０に電極端子１１２および第２端子１４０を貫通させて、軸部１３１を２つの端子１１２，１４０に荷重がかかった状態となるように回転させればよいので、端子１１２，１４０間の接続にボルト締結が不要であり、端子間接続作業の作業効率が向上する。 (Operation and effect of this embodiment)
According to the present embodiment, as in the first embodiment, the electrode member 112 and the second terminal 140 are passed through the rotating member 130 so that the shaft portion 131 is in a state where a load is applied to the two terminals 112 and 140. Therefore, it is not necessary to fasten the bolts for the connection between the terminals 112 and 140, and the work efficiency of the inter-terminal connection work is improved.
　また、本実施形態によれば、押圧部１３２と、電極端子１１２との間に挟持された皿バネ１３５を備えているから、端子１１２，１４０の板厚方向における公差を吸収することができる。 In addition, according to the present embodiment, since the disc spring 135 sandwiched between the pressing portion 132 and the electrode terminal 112 is provided, the tolerance in the plate thickness direction of the terminals 112 and 140 can be absorbed.
　また、本実施形態によれば、第１端子１１２は、単電池１１１に設けられた電極端子１１２であるから、単電池１１１を複数接続して電池モジュールＭを構成するときや複数の電池モジュールＭを接続する際の接続作業の作業効率が向上する。 In addition, according to the present embodiment, the first terminal 112 is the electrode terminal 112 provided in the unit cell 111. Therefore, when the battery module M is configured by connecting a plurality of unit cells 111, or the plurality of battery modules M. The work efficiency of the connection work when connecting is improved.
　また、本実施形態によれば、回転部材１３０の回動操作を治具により行うようになっているので、端子１１２，１４０に直接指が触れることがなく安全性が高い。 Further, according to the present embodiment, since the rotating operation of the rotating member 130 is performed by the jig, the finger is not directly touched on the terminals 112 and 140 and the safety is high.
　さらに本実施形態によれば、単電池１１１の電極端子１１２の第２端子１４０との接続部１１３が単電池１１１の端子形成面１１４Ａと対向するように配されるとともに、回転部材１３０の押圧部１３２が、電極端子１１２と単電池１１１の端子形成面１１４Ａとの間に配されているので、端子接続部品１００の低背化を図ることができる。 Furthermore, according to the present embodiment, the connection portion 113 of the electrode terminal 112 of the unit cell 111 with the second terminal 140 is disposed so as to face the terminal forming surface 114A of the unit cell 111, and the pressing portion of the rotating member 130 is provided. Since 132 is disposed between the electrode terminal 112 and the terminal formation surface 114A of the unit cell 111, the terminal connection component 100 can be reduced in height.
　また、本実施形態によれば、単電池１１１に組み込まれている回転部材１３０の軸部１３１には電極端子１１２が貫通されており、第２端子１４０および規制部材１２７を軸部１３１の延びる方向（上下方向）から組み付けていけばよいので組み付け作業を簡素化することができる。 Further, according to the present embodiment, the electrode terminal 112 is passed through the shaft portion 131 of the rotating member 130 incorporated in the unit cell 111, and the second terminal 140 and the regulating member 127 are extended in the direction in which the shaft portion 131 extends. Since it is only necessary to assemble from the (up and down direction), the assembling work can be simplified.
　加えて本実施形態によれば、端子接続部品１００を収容するハウジング１２０を覆うハウジングカバー１２４を取り付けることにより、回転ピン１３３の移動が規制され、これにより、電極端子１１２と第２端子１４０との接続状態を電気的な接続が可能な荷重のかかった状態で維持することができるので、電極端子１１２と第２端子１４０との電気的な接続を信頼性の高いものとすることができる。 In addition, according to the present embodiment, the movement of the rotation pin 133 is restricted by attaching the housing cover 124 that covers the housing 120 that houses the terminal connection component 100, and thereby, the electrode terminal 112 and the second terminal 140 are moved. Since the connection state can be maintained in a state where a load capable of electrical connection is applied, the electrical connection between the electrode terminal 112 and the second terminal 140 can be made highly reliable.
