以下、この発明の実施の形態を添付図面に基づいて説明する。
実施の形態１
図１に、この発明の実施の形態１に係るメス端子部材１０を示す。メス端子部材１０は、単電池の正の電極および負の電極に共通して取り付けられるもので、帯状の板材の両端を互いに接続するように折り曲げて形成された周壁部１１を有している。周壁部１１は、互いに直交する２本の直線Ｌ１およびＬ２に沿ってそれぞれ延びる、ほぼ十字形の断面形状を有している。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1
FIG. 1 shows a female terminal member 10 according to Embodiment 1 of the present invention. The female terminal member 10 is attached in common to the positive electrode and the negative electrode of the unit cell, and has a peripheral wall portion 11 formed by bending both ends of the strip-shaped plate material so as to be connected to each other. The peripheral wall portion 11 has a substantially cross-shaped cross-sectional shape that extends along two straight lines L1 and L2 orthogonal to each other.

直線Ｌ１およびＬ２のうち、一方の直線Ｌ１に沿って延びる部分の周壁部１１の上端から周壁部１１の内側に向けて４本の第１の板バネ１２が湾曲形成されている。これら４本の第１の板バネ１２は、直線Ｌ１およびＬ２の交差点Ｃを挟んで交差点Ｃの両側に２本ずつ分かれて配置され、それぞれ２本の第１の板バネ１２が互いに対向し、これにより、直線Ｌ１に沿った直線状の第１の挿入口１３を有する第１のスロット１４が形成されている。すなわち、第１の板バネ１２は、第１の挿入口１３を弾性的に閉じるように接点を形成している。   Of the straight lines L1 and L2, four first leaf springs 12 are curvedly formed from the upper end of the peripheral wall portion 11 of the portion extending along one straight line L1 toward the inside of the peripheral wall portion 11. These four first leaf springs 12 are arranged separately on both sides of the intersection C across the intersection C of the straight lines L1 and L2, and the two first leaf springs 12 face each other, Thereby, the 1st slot 14 which has the linear 1st insertion slot 13 along the straight line L1 is formed. That is, the first leaf spring 12 forms a contact so as to close the first insertion port 13 elastically.

同様に、他方の直線Ｌ２に沿って延びる部分の周壁部１１の上端から周壁部１１の内側に向けて４本の第２の板バネ１５が湾曲形成されている。これら４本の第２の板バネ１５は、直線Ｌ１およびＬ２の交差点Ｃを挟んで交差点Ｃの両側に２本ずつ分かれて配置され、それぞれ２本の第２の板バネ１５が互いに対向し、これにより、直線Ｌ２に沿った直線状の第２の挿入口１６を有する第２のスロット１７が形成されている。すなわち、第２の板バネ１５は、第２の挿入口１６を弾性的に閉じるように接点を形成している。
また、周壁部１１の下部には下方に延びる脚部１８が連結され、この脚部１８に取付孔１９が形成されている。取付孔１９は、ボルト等を用いてメス端子部材１０を単電池の電極に取り付けるためのものである。 Similarly, four second leaf springs 15 are curvedly formed from the upper end of the peripheral wall portion 11 of the portion extending along the other straight line L2 toward the inside of the peripheral wall portion 11. These four second leaf springs 15 are arranged separately on both sides of the intersection C across the intersection C of the straight lines L1 and L2, and the two second leaf springs 15 face each other, Thereby, the second slot 17 having the linear second insertion port 16 along the straight line L2 is formed. That is, the second leaf spring 15 forms a contact so as to close the second insertion port 16 elastically.
A leg 18 extending downward is connected to the lower portion of the peripheral wall 11, and a mounting hole 19 is formed in the leg 18. The attachment hole 19 is for attaching the female terminal member 10 to the electrode of the unit cell using a bolt or the like.

図２に示されるように、第１のスロット１４の第１の挿入口１３および第２のスロット１７の第２の挿入口１６は、それぞれ直線Ｌ１およびＬ２に沿っており、交差点Ｃを中心として、互いに９０度の角度で交差している。
また、第１の板バネ１２および第２の板バネ１５は、それぞれ周壁部１１の上端から二股に分かれて互いに平行に延びる２本の線状部２０から形成されている。
なお、周壁部１１は、直線Ｌ１およびＬ２に沿った方向に、それぞれ幅Ｗの内部寸法を有している。 As shown in FIG. 2, the first insertion slot 13 of the first slot 14 and the second insertion slot 16 of the second slot 17 are along straight lines L1 and L2, respectively, with the intersection C as the center. , Cross each other at an angle of 90 degrees.
The first plate spring 12 and the second plate spring 15 are each formed of two linear portions 20 that are divided into two branches from the upper end of the peripheral wall portion 11 and extend in parallel with each other.
The peripheral wall portion 11 has an internal dimension of a width W in the direction along the straight lines L1 and L2.

このようなメス端子部材１０は、導電性を有する金属板２１を、図３に示されるような形状に切り抜いた後、折り曲げ加工することで作製することができる。帯状部２２が周壁部１１を形成し、帯状部２２の下辺に接続された同一形状の一対の板状部２３が重ね合わされて脚部１８を形成し、帯状部２２の上辺に接続された１６本の線状部２０から第１の板バネ１２および第２の板バネ１５が形成される。   Such a female terminal member 10 can be produced by cutting a conductive metal plate 21 into a shape as shown in FIG. 3 and then bending it. The belt-like portion 22 forms the peripheral wall portion 11, and a pair of plate-like portions 23 having the same shape connected to the lower side of the belt-like portion 22 are overlapped to form the leg portion 18, and 16 connected to the upper side of the belt-like portion 22. A first leaf spring 12 and a second leaf spring 15 are formed from the linear portion 20 of the book.

図４に、メス端子部材１０が取り付けられた単電池３０を示す。単電池３０は、ほぼ直方体形状の絶縁ケース３１を有し、絶縁ケース３１の内部に所定の起電力を有するセル部分が収容されている。絶縁ケース３１の上部の一端に正の電極３２、他端に負の電極３３が露出しており、これらの電極３２および３３に、それぞれメス端子部材１０が固定されている。メス端子部材１０は、第１のスロット１４および第２のスロット１７が上方を向くように、取付孔１９を利用してボルト３４により取り付けられている。
絶縁ケース３１は、このように電極３２および３３にそれぞれ取り付けられたメス端子部材１０の上部を覆うように天井部３５を有しており、この天井部３５に、双方のメス端子部材１０の第１のスロット１４および第２のスロット１７に対向する開口部３６が形成されている。 FIG. 4 shows a cell 30 to which the female terminal member 10 is attached. The unit cell 30 has an insulating case 31 having a substantially rectangular parallelepiped shape, and a cell portion having a predetermined electromotive force is accommodated inside the insulating case 31. A positive electrode 32 is exposed at one end of the upper portion of the insulating case 31, and a negative electrode 33 is exposed at the other end, and the female terminal member 10 is fixed to these electrodes 32 and 33, respectively. The female terminal member 10 is attached by bolts 34 using the attachment holes 19 so that the first slot 14 and the second slot 17 face upward.
The insulating case 31 has a ceiling part 35 so as to cover the upper part of the female terminal member 10 attached to the electrodes 32 and 33 in this way. An opening 36 is formed to face the first slot 14 and the second slot 17.

正の電極３２に取り付けられたメス端子部材１０も、負の電極３３に取り付けられたメス端子部材１０も、第１のスロット１４の第１の挿入口１３および第２のスロット１７の第２の挿入口１６が、それぞれほぼ直方体形状の絶縁ケース３１に対して４５度の角度を成すように取り付けられている。図５に示されるように、絶縁ケース３１の天井部３５の開口部３６は、メス端子部材１０の第１の挿入口１３および第２の挿入口１６に対応して、絶縁ケース３１に対し４５度の角度を成す十字形状を有している。   The female terminal member 10 attached to the positive electrode 32 and the female terminal member 10 attached to the negative electrode 33 are both the first insertion port 13 of the first slot 14 and the second slot 17 of the second slot 17. The insertion openings 16 are attached so as to form an angle of 45 degrees with respect to each of the substantially rectangular parallelepiped insulating cases 31. As shown in FIG. 5, the opening 36 of the ceiling portion 35 of the insulating case 31 is 45 to the insulating case 31 corresponding to the first insertion port 13 and the second insertion port 16 of the female terminal member 10. It has a cross shape with an angle of degrees.

なお、開口部３６から絶縁ケース３１の天井部３５の近接する各辺までの距離Ｅは、いずれの辺に対しても同一の値を有しているものとする。このため、複数の単電池３０を、絶縁ケース３１の天井部３５の対応する辺が互いに重なるように配列したときには、互いに近接する単電池３０の互いに近接する開口部３６の間隔は「２×Ｅ」となり、互いに近接する開口部３６の直下に位置する一対のメス端子部材１０の間隔も「２×Ｅ」となる。
また、このとき、これら一対のメス端子部材１０の第１の挿入口１３および第２の挿入口１６は、互いに９０度の角度を成す位置関係となる。
このような開口部３６を有する天井部３５によりメス端子部材１０の上部が覆われているため、メス端子部材１０に直接接触して感電することが未然に防止されている。 It is assumed that the distance E from the opening 36 to each adjacent side of the ceiling portion 35 of the insulating case 31 has the same value for any side. Therefore, when the plurality of unit cells 30 are arranged so that the corresponding sides of the ceiling portion 35 of the insulating case 31 overlap each other, the interval between the adjacent opening portions 36 of the unit cells 30 that are close to each other is “2 × E. And the interval between the pair of female terminal members 10 located immediately below the opening 36 close to each other is also “2 × E”.
At this time, the first insertion port 13 and the second insertion port 16 of the pair of female terminal members 10 are in a positional relationship that forms an angle of 90 degrees with each other.
Since the upper portion of the female terminal member 10 is covered with the ceiling portion 35 having such an opening 36, it is possible to prevent an electric shock by directly contacting the female terminal member 10.

図６に、メス端子部材１０に対応して使用されるオス端子部材４０の構成を示す。オス端子部材４０は、平板形状の保持部４１を有し、保持部４１の両端に、それぞれ保持部４１に対して垂直な同一方向に突出する一対の板状端子４２が形成されている。これらの板状端子４２は、互いに９０度の角度を成すように配置され、それぞれの先端部が２つの板状の分割端部４３に分割されている。
また、保持部４１には、一対の板状端子４２の付け根部分にそれぞれ近接して、保持部４１を貫通する孔からなる一対の開口部４４が形成されている。それぞれの開口部４４は、１つの分割端部４３が挿入可能となるような大きさを有している。
さらに、保持部４１には、電池の電圧を監視する際に、計測用の端子を接続するための係止孔４５が形成されている。 In FIG. 6, the structure of the male terminal member 40 used corresponding to the female terminal member 10 is shown. The male terminal member 40 has a flat plate-shaped holding portion 41, and a pair of plate-like terminals 42 that protrude in the same direction perpendicular to the holding portion 41 are formed at both ends of the holding portion 41. These plate-like terminals 42 are arranged so as to form an angle of 90 degrees with each other, and each tip portion is divided into two plate-like divided end portions 43.
In addition, the holding portion 41 is formed with a pair of opening portions 44 each formed of a hole penetrating the holding portion 41 in proximity to the base portions of the pair of plate-like terminals 42. Each opening 44 has a size such that one split end 43 can be inserted.
Further, the holding portion 41 is formed with a locking hole 45 for connecting a measurement terminal when the battery voltage is monitored.

一対の板状端子４２の間隔は、組電池を形成するために複数の単電池３０を配列したときに、互いに隣接する単電池３０の互いに近接するメス端子部材１０の間隔、すなわち、「２×Ｅ」の値に予め設定されている。
また、それぞれの板状端子４２の幅は、メス端子部材１０の直線Ｌ１およびＬ２の交差点Ｃを挟んで交差点Ｃの両側に配置されている第１の板バネ１２または第２の板バネ１５にまたがるのに十分で且つ、周壁部１１の直線Ｌ１およびＬ２に沿った内部寸法Ｗより小さい値に設定されている。 The interval between the pair of plate-like terminals 42 is the interval between the adjacent female terminal members 10 of the adjacent unit cells 30 when the plurality of unit cells 30 are arranged to form an assembled battery, that is, “2 × E ”is preset.
Further, the width of each plate-like terminal 42 is such that the first plate spring 12 or the second plate spring 15 disposed on both sides of the intersection C across the intersection C of the straight lines L1 and L2 of the female terminal member 10 is arranged. It is sufficient to straddle and is set to a value smaller than the internal dimension W along the straight lines L1 and L2 of the peripheral wall portion 11.

これにより、複数の単電池３０を配列したときに、互いに隣接する単電池３０の互いに近接する一対のメス端子部材１０の第１のスロット１４または第２のスロット１７に、オス端子部材４０の一対の板状端子４２をそれぞれ挿入することができるようになる。例えば、図７に示されるように、オス端子部材４０の一対の板状端子４２のうち、一方の板状端子４２が一方のメス端子部材１０の第１のスロット１４に挿入されると同時に、他方の板状端子４２が他方のメス端子部材１０の第２のスロット１７に挿入される。
オス端子部材４０の一対の板状端子４２は、それぞれ対応するメス端子部材１０の第１のスロット１４の第１の挿入口１３および第２のスロット１７の第２の挿入口１６に挿入され、オス端子部材４０を介して双方のメス端子部材１０が電気的に接続される。 Thus, when the plurality of unit cells 30 are arranged, the pair of male terminal members 40 is placed in the first slot 14 or the second slot 17 of the pair of female terminal members 10 adjacent to each other in the unit cells 30 adjacent to each other. Each of the plate-like terminals 42 can be inserted. For example, as shown in FIG. 7, one of the pair of plate terminals 42 of the male terminal member 40 is inserted into the first slot 14 of the one female terminal member 10 at the same time, The other plate-like terminal 42 is inserted into the second slot 17 of the other female terminal member 10.
The pair of plate-like terminals 42 of the male terminal member 40 are respectively inserted into the first insertion port 13 of the first slot 14 and the second insertion port 16 of the second slot 17 of the corresponding female terminal member 10. Both female terminal members 10 are electrically connected via the male terminal member 40.

上述したように、オス端子部材４０の保持部４１には、１つの分割端部４３が挿入可能となるような大きさの開口部４４が形成されているので、図８に示されるように、一方のオス端子部材４０の開口部４４に他方のオス端子部材４０の板状端子４２の１つの分割端部４３を挿入することで、２つのオス端子部材４０を互いに組み合わせることができる。   As described above, since the holding portion 41 of the male terminal member 40 is formed with the opening 44 having such a size that one split end 43 can be inserted, as shown in FIG. By inserting one split end 43 of the plate-like terminal 42 of the other male terminal member 40 into the opening 44 of one male terminal member 40, the two male terminal members 40 can be combined with each other.

次に、メス端子部材１０が装着された複数の単電池３０をオス端子部材４０により接続して組電池とする方法について説明する。
まず、図９に、４つの単電池３０ａ〜３０ｄを直列接続した組電池を示す。単電池３０ａ〜３０ｄは、それぞれ図４および５に示した単電池３０と同一の構造を有しており、正の電極と負の電極を交互に反対方向に向けて、互いに隣接する単電池の正の電極と負の電極が互いに近接する電極対を形成するように４つの単電池３０ａ〜３０ｄを配列する。 Next, a method of connecting a plurality of single cells 30 to which the female terminal member 10 is mounted with the male terminal member 40 to form an assembled battery will be described.
First, FIG. 9 shows an assembled battery in which four unit cells 30a to 30d are connected in series. The unit cells 30a to 30d have the same structure as that of the unit cell 30 shown in FIGS. 4 and 5, respectively. The unit cells 30a to 30d are adjacent to each other with the positive and negative electrodes alternately directed in opposite directions. Four unit cells 30a to 30d are arranged so that the positive electrode and the negative electrode form an electrode pair close to each other.

そして、互いに近接する複数の電極対を、交互に、オス端子部材４０を用いて接続する。すなわち、単電池３０ａの正の電極と単電池３０ｂの負の電極をオス端子部材４０により接続し、単電池３０ｂの正の電極と単電池３０ｃの負の電極をオス端子部材４０により接続し、単電池３０ｃの正の電極と単電池３０ｄの負の電極をオス端子部材４０により接続する。
このとき、図７に示すように、互いに近接する複数の電極対のうち、一方の電極に取り付けられたメス端子部材１０の第１のスロット１４と他方の電極に取り付けられたメス端子部材１０の第２のスロット１７に、オス端子部材４０の一対の板状端子４２がそれぞれ対応する単電池の絶縁ケース３１の開口部３６を介して挿入される。 Then, a plurality of electrode pairs that are close to each other are connected alternately using the male terminal member 40. That is, the positive electrode of the cell 30a and the negative electrode of the cell 30b are connected by the male terminal member 40, the positive electrode of the cell 30b and the negative electrode of the cell 30c are connected by the male terminal member 40, The positive electrode of the cell 30 c and the negative electrode of the cell 30 d are connected by the male terminal member 40.
At this time, as shown in FIG. 7, among the plurality of electrode pairs adjacent to each other, the first slot 14 of the female terminal member 10 attached to one electrode and the female terminal member 10 attached to the other electrode A pair of plate-like terminals 42 of the male terminal member 40 are inserted into the second slots 17 through the openings 36 of the corresponding cell insulation cases 31.

なお、直列接続の両端部となる、単電池３０ａの負の電極と単電池３０ｄの正の電極には、それぞれ出力取り出し用の端子部材４６が接続されている。端子部材４６も、オス端子部材４０の板状端子４２と同様の１つの板状端子を有しており、この板状端子を対応するメス端子部材１０の第１のスロット１４または第２のスロット１７に挿入することで、対応する単電池の電極に接続される。   Note that output terminal members 46 are connected to the negative electrode of the unit cell 30a and the positive electrode of the unit cell 30d, which are both ends of the series connection. The terminal member 46 also has one plate-like terminal similar to the plate-like terminal 42 of the male terminal member 40, and this plate-like terminal is the first slot 14 or the second slot of the corresponding female terminal member 10. By being inserted into the terminal 17, it is connected to the corresponding unit cell electrode.

次に、図１０に、４つの単電池３０ａ〜３０ｄを並列接続した組電池を示す。それぞれ正の電極と負の電極を同一方向に向けて、互いに隣接する単電池の正の電極同士または負の電極同士が互いに近接する電極対を形成するように４つの単電池３０ａ〜３０ｄを配列する。   Next, FIG. 10 shows an assembled battery in which four unit cells 30a to 30d are connected in parallel. Four unit cells 30a to 30d are arranged so that positive electrodes and negative electrodes are directed in the same direction, and positive electrodes of adjacent unit cells or electrode pairs in which negative electrodes are close to each other are formed. To do.

そして、互いに近接する複数の電極対を、それぞれオス端子部材４０を用いて接続する。すなわち、４つの単電池３０ａ〜３０ｄの正の電極同士をそれぞれオス端子部材４０を用いて順次接続し、４つの単電池３０ａ〜３０ｄの負の電極同士をそれぞれオス端子部材４０を用いて順次接続する。例えば、単電池３０ｂの負の電極に取り付けられたメス端子部材１０においては、隣接する単電池３０ａの負の電極との接続を行うためにオス端子部材４０の板状端子４２が第１のスロット１４に挿入されると共に、このオス端子部材４０の上から、反対方向に隣接する単電池３０ｃの負の電極との接続を行うためのオス端子部材４０の板状端子４２が第２のスロット１７に挿入される。これにより、単電池３０ｂの負の電極が隣接する単電池３０ａの負の電極および単電池３０ｃの負の電極にそれぞれ接続される。   Then, a plurality of electrode pairs adjacent to each other are connected using the male terminal member 40. That is, the positive electrodes of the four unit cells 30 a to 30 d are sequentially connected using the male terminal member 40, and the negative electrodes of the four unit cells 30 a to 30 d are sequentially connected to each other using the male terminal member 40. To do. For example, in the female terminal member 10 attached to the negative electrode of the unit cell 30b, the plate-like terminal 42 of the male terminal member 40 is the first slot in order to connect to the negative electrode of the adjacent unit cell 30a. 14 and the plate-like terminal 42 of the male terminal member 40 for connecting to the negative electrode of the unit cell 30c adjacent in the opposite direction from above the male terminal member 40 is the second slot 17. Inserted into. Thereby, the negative electrode of the single battery 30b is connected to the negative electrode of the adjacent single battery 30a and the negative electrode of the single battery 30c, respectively.

このとき、図８に示したように、単電池３０ｂの負の電極に取り付けられたメス端子部材１０に嵌合される２つのオス端子部材４０のうち、一方のオス端子部材４０の開口部４４に他方のオス端子部材４０の板状端子４２の１つの分割端部４３を挿入することで、２つのオス端子部材４０を互いに組み合わせた状態で、メス端子部材１０の第１のスロット１４および第２のスロット１７にそれぞれ対応するオス端子部材４０の板状端子４２を挿入することができる。   At this time, as shown in FIG. 8, the opening 44 of one male terminal member 40 out of the two male terminal members 40 fitted to the female terminal member 10 attached to the negative electrode of the unit cell 30b. By inserting one split end 43 of the plate-like terminal 42 of the other male terminal member 40 into the first slot 14 and the second slot of the female terminal member 10 in a state where the two male terminal members 40 are combined with each other. The plate-like terminals 42 of the male terminal member 40 respectively corresponding to the two slots 17 can be inserted.

同様にして、４つの単電池３０ａ〜３０ｄの正の電極同士を順次接続すると共に負の電極同士を順次接続することで、４つの単電池３０ａ〜３０ｄを並列接続した組電池が構成される。
このように、配列される単電池３０ａ〜３０ｄのそれぞれの向きとメス端子部材１０に嵌合されるオス端子部材４０の位置および個数を変更するだけで、極めて容易に直列接続と並列接続を切り替えることができる。 Similarly, an assembled battery in which the four unit cells 30a to 30d are connected in parallel is configured by sequentially connecting the positive electrodes of the four unit cells 30a to 30d and sequentially connecting the negative electrodes to each other.
As described above, the series connection and the parallel connection can be switched very easily only by changing the orientation of each of the arranged cells 30a to 30d and the position and number of the male terminal members 40 fitted to the female terminal member 10. be able to.

上述したように、単電池３０の開口部３６から絶縁ケース３１の天井部３５の近接する各辺までの距離Ｅは、いずれの辺に対しても同一の値を有しているので、図９および１０の組電池のように、絶縁ケース３１の天井部３５の長辺同士を接触させて複数の単電池３０を配列させても、天井部３５の短辺同士を接触させて複数の単電池３０を配列させても、互いに近接する単電池３０の互いに近接する開口部３６の間隔は同じ「２×Ｅ」となる。すなわち、互いに近接する単電池３０の互いに近接するメス端子部材１０の間隔も「２×Ｅ」となる。   As described above, since the distance E from the opening 36 of the unit cell 30 to the adjacent sides of the ceiling portion 35 of the insulating case 31 has the same value for all sides, FIG. As in the assembled battery 10 and 10, even when the long sides of the ceiling portion 35 of the insulating case 31 are brought into contact with each other and the plurality of single cells 30 are arranged, the short sides of the ceiling portion 35 are brought into contact with each other. Even when 30 are arranged, the interval between the opening portions 36 adjacent to each other in the unit cells 30 adjacent to each other is the same “2 × E”. That is, the interval between the female terminal members 10 adjacent to each other in the unit cells 30 adjacent to each other is also “2 × E”.

このため、例えば、図１１に示されるように、複数の単電池３０を縦横双方にそれぞれ互いに接触させながらマトリクス状に配列しても、互いに近接する単電池３０の互いに近接する電極同士を、共通のオス端子部材４０を用いて接続することができる。図１１に示した組電池は、８個の単電池３０を直列接続したものである。
また、図１２には、２個の単電池３０を互いに並列接続したものを４組直列接続した組電池を示している。
このように、単電池３０の配列方向とオス端子部材４０の位置および個数を選択することにより、複数の単電池３０を自由に組み合わせて、直列接続、並列接続、あるいは直列と並列が混在した接続を有する組電池を容易に形成することができる。
さらに、組電池の形成に用いられた複数のオス端子部材４０にそれぞれ形成されている係止孔４５を利用して、組電池の適宜箇所の電圧を容易に計測することができる。 Therefore, for example, as shown in FIG. 11, even if a plurality of unit cells 30 are arranged in a matrix while being in contact with each other both vertically and horizontally, the adjacent electrodes of the unit cells 30 that are adjacent to each other are shared. The male terminal member 40 can be used for connection. The assembled battery shown in FIG. 11 has eight unit cells 30 connected in series.
FIG. 12 shows an assembled battery in which four sets of two unit cells 30 connected in parallel are connected in series.
In this way, by selecting the arrangement direction of the cells 30 and the position and number of the male terminal members 40, a plurality of the cells 30 can be freely combined to provide series connection, parallel connection, or connection in which series and parallel are mixed. It is possible to easily form a battery pack having
Furthermore, the voltage of the appropriate location of an assembled battery can be easily measured using the locking hole 45 each formed in the some male terminal member 40 used for formation of an assembled battery.

ここで、図５に示したように、単電池３０の開口部３６から絶縁ケース３１の天井部３５の近接する各辺までの距離Ｅは、いずれの辺に対しても同一の値を有しているので、複数の単電池３０を配列した際には、図１３に示されるように、互いに近接する単電池３０の互いに近接する一対のメス端子部材１０は、予め定められた位置関係となり、これらのメス端子部材１０に対して対称的にオス端子部材４０が嵌合される。   Here, as shown in FIG. 5, the distance E from the opening 36 of the unit cell 30 to the adjacent sides of the ceiling portion 35 of the insulating case 31 has the same value for any side. Therefore, when a plurality of unit cells 30 are arranged, as shown in FIG. 13, the pair of adjacent female terminal members 10 of the unit cells 30 that are adjacent to each other are in a predetermined positional relationship, The male terminal member 40 is fitted symmetrically with respect to the female terminal members 10.

ただし、メス端子部材１０の第１のスロット１４および第２のスロット１７は、それぞれ第１の板バネ１２および第２の板バネ１５が第１の挿入口１３および第２の挿入口１６を弾性的に閉じるように接点を形成し、これら第１の挿入口１３および第２の挿入口１６にオス端子部材４０の板状端子４２が挿入されるので、単電池３０の製造公差および複数の単電池３０の配列ズレ等に起因して、互いに近接する一対のメス端子部材１０の位置関係が縦方向、横方向および高さ方向にズレた場合であっても、ズレ量が許容範囲内であれば、そのズレを吸収して一対のメス端子部材１０にオス端子部材４０を嵌合させることができる。   However, in the first slot 14 and the second slot 17 of the female terminal member 10, the first leaf spring 12 and the second leaf spring 15 respectively elastically move the first insertion port 13 and the second insertion port 16. Since the plate-like terminal 42 of the male terminal member 40 is inserted into the first insertion port 13 and the second insertion port 16, the manufacturing tolerance of the unit cell 30 and the plurality of unit Even if the positional relationship between the pair of female terminal members 10 that are close to each other is shifted in the vertical direction, the horizontal direction, and the height direction due to the displacement of the battery 30 or the like, the amount of shift is within an allowable range. For example, the male terminal member 40 can be fitted to the pair of female terminal members 10 by absorbing the deviation.

例えば、図１４に示されるように、一対のメス端子部材１０が、横方向には正規の間隔「２×Ｅ」を保持しつつ、縦方向にズレ量ΔＤだけズレた場合でも、オス端子部材４０の板状端子４２の幅が、それぞれのメス端子部材１０の内部寸法Ｗより小さい値に設定されているため、ズレ量ΔＤがメス端子部材１０の内部寸法Ｗとオス端子部材４０の板状端子４２の幅との差分により決定される許容範囲以内であれば、メス端子部材１０の第１のスロット１４または第２のスロット１７に対するオス端子部材４０の板状端子４２の挿入位置をメス端子部材１０の内部で調整することで、オス端子部材４０は一対のメス端子部材１０に嵌合されることとなる。   For example, as shown in FIG. 14, even if the pair of female terminal members 10 are displaced by the amount of deviation ΔD in the vertical direction while maintaining a regular interval “2 × E” in the horizontal direction, Since the width of the 40 plate-like terminals 42 is set to a value smaller than the internal dimension W of each female terminal member 10, the deviation amount ΔD is equal to the internal dimension W of the female terminal member 10 and the plate shape of the male terminal member 40. If it is within the allowable range determined by the difference with the width of the terminal 42, the insertion position of the plate-like terminal 42 of the male terminal member 40 with respect to the first slot 14 or the second slot 17 of the female terminal member 10 is determined as the female terminal. By adjusting the inside of the member 10, the male terminal member 40 is fitted into the pair of female terminal members 10.

同様に、図１５に示されるように、一対のメス端子部材１０が、横方向に正規の間隔「２×Ｅ」からズレ量ΔＥだけズレた場合でも、ズレ量ΔＥが許容範囲以内であれば、メス端子部材１０の第１のスロット１４または第２のスロット１７に対するオス端子部材４０の板状端子４２の挿入位置をメス端子部材１０の内部で調整することで、オス端子部材４０は一対のメス端子部材１０に嵌合される。
さらに、図１６に示されるように、一対のメス端子部材１０が、高さ方向にズレ量ΔＨだけズレた場合であっても、メス端子部材１０の第１のスロット１４または第２のスロット１７に対するオス端子部材４０の板状端子４２の挿入量が変化するだけで、オス端子部材４０を一対のメス端子部材１０に嵌合させることができる。
このため、単電池３０の製造公差および複数の単電池３０の配列ズレ等に起因して、近接する一対のメス端子部材１０の位置関係にズレが生じた場合でも、そのズレを矯正することなく、容易に組電池を形成することが可能となる。 Similarly, as shown in FIG. 15, even when the pair of female terminal members 10 are displaced by the amount of deviation ΔE from the regular interval “2 × E” in the lateral direction, if the amount of deviation ΔE is within the allowable range. By adjusting the insertion position of the plate-like terminal 42 of the male terminal member 40 with respect to the first slot 14 or the second slot 17 of the female terminal member 10 within the female terminal member 10, the male terminal member 40 has a pair of The female terminal member 10 is fitted.
Further, as shown in FIG. 16, even when the pair of female terminal members 10 are displaced by a deviation amount ΔH in the height direction, the first slot 14 or the second slot 17 of the female terminal member 10. The male terminal member 40 can be fitted to the pair of female terminal members 10 only by changing the amount of insertion of the plate-like terminal 42 of the male terminal member 40 relative to the pair of female terminal members 10.
For this reason, even when the positional relationship between the pair of female terminal members 10 adjacent to each other due to the manufacturing tolerance of the unit cells 30 and the misalignment of the plurality of unit cells 30 occurs, the deviation is not corrected. Thus, an assembled battery can be easily formed.

なお、図１７に示されるように、オス端子部材４０の上に絶縁体からなる絶縁カバー５０を被せて、この状態で組電池を形成することもできる。
絶縁カバー５０には、オス端子部材４０の一対の開口部４４にそれぞれ対応した一対の開口部５１が形成されており、この絶縁カバー５０をオス端子部材４０の上に被せることにより、オス端子部材４０の保持部４１は、一対の開口部４４を除いた部分が絶縁カバー５０により覆われ、図１８に示されるように、一対の板状端子４２が絶縁カバー５０から下方へ突き出た状態となる。 As shown in FIG. 17, the assembled battery can be formed in this state by covering the male terminal member 40 with an insulating cover 50 made of an insulator.
The insulating cover 50 is formed with a pair of openings 51 corresponding to the pair of openings 44 of the male terminal member 40. By covering the insulating cover 50 on the male terminal member 40, the male terminal member is formed. In the holding portion 41 of 40, a portion excluding the pair of openings 44 is covered with the insulating cover 50, and the pair of plate-like terminals 42 protrudes downward from the insulating cover 50 as shown in FIG. .

このような絶縁カバー５０を用いることで、組電池を形成した後に、オス端子部材４０の導電部分に直接接触して感電することを防止することができる。
また、オス端子部材４０の開口部４４に対応する開口部５１が絶縁カバー５０に形成されているため、絶縁カバー５０をオス端子部材４０の上に被せた状態でも、絶縁カバー５０の開口部５１およびオス端子部材４０の開口部４４を通して他のオス端子部材４０の板状端子４２の１つの分割端部４３を挿入することで、図８に示したように、２つのオス端子部材４０を互いに組み合わせることができる。
絶縁カバー５０でオス端子部材４０の保持部４１を覆う代わりに、オス端子部材４０の保持部４１の表面上に電気絶縁性を有する絶縁膜を形成しても、感電防止を行うことができる。 By using such an insulating cover 50, it is possible to prevent an electric shock by directly contacting the conductive portion of the male terminal member 40 after the assembled battery is formed.
Further, since the opening 51 corresponding to the opening 44 of the male terminal member 40 is formed in the insulating cover 50, the opening 51 of the insulating cover 50 can be obtained even when the insulating cover 50 is placed on the male terminal member 40. And by inserting one split end portion 43 of the plate-like terminal 42 of the other male terminal member 40 through the opening 44 of the male terminal member 40, the two male terminal members 40 are connected to each other as shown in FIG. Can be combined.
Instead of covering the holding part 41 of the male terminal member 40 with the insulating cover 50, electric shock can be prevented even if an insulating film having electrical insulation is formed on the surface of the holding part 41 of the male terminal member 40.

なお、図６に示したオス端子部材４０は、他のオス端子部材４０の板状端子４２の１つの分割端部４３を挿入するための開口部４４が保持部４１を貫通する孔から形成されていたが、これに限るものではなく、例えば、図１９に示されるオス端子部材４０Ａのように、保持部４１Ａから板状端子４２Ａの先端まで延びるスリット４４Ａを形成し、このスリット４４Ａを開口部として使用することもできる。この場合、スリット４４Ａにより、板状端子４２Ａの全体が２つの分割端部４３Ａに分割されている。
このようなオス端子部材４０Ａを用いても、複数の単電池３０の直列接続、並列接続、あるいは直列と並列が混在した接続を有する組電池を構成することができ、また、図８に示したように、２つのオス端子部材４０Ａを互いに組み合わせることができる。 The male terminal member 40 shown in FIG. 6 has an opening 44 for inserting one split end 43 of the plate-like terminal 42 of another male terminal member 40 formed from a hole penetrating the holding portion 41. However, the present invention is not limited to this. For example, like the male terminal member 40A shown in FIG. 19, a slit 44A extending from the holding portion 41A to the tip of the plate-like terminal 42A is formed, and the slit 44A is formed as an opening. It can also be used as In this case, the entire plate-like terminal 42A is divided into two divided end portions 43A by the slit 44A.
Even if such a male terminal member 40A is used, an assembled battery having a series connection, a parallel connection, or a connection in which a series and a parallel are mixed can be configured, as shown in FIG. Thus, the two male terminal members 40A can be combined with each other.

上記の実施の形態１では、１種類の共通したオス端子部材４０または４０Ａのみを用いて複数の単電池３０の直列接続、並列接続等を行ったが、必ずしも、共通したオス端子部材を用いなくてもよい。
例えば、図２０（Ａ）に示されるように、一対の板状端子４２Ｂの付け根部分にそれぞれ近接して保持部４１Ｂに一対の開口部４４Ｂが形成されるものの、それぞれの板状端子４２Ｂの先端部が分割されていない第１のオス端子部材４０Ｂと、図２０（Ｂ）に示されるように、一対の板状端子４２Ｃの先端部がそれぞれ２つの分割端部４３Ｃに分割されているものの、保持部４１Ｃに開口部が形成されていない第２のオス端子部材４０Ｃを使用することもできる。 In the first embodiment, only one type of common male terminal member 40 or 40A is used to connect the plurality of single cells 30 in series, parallel connection, etc., but the common male terminal member is not necessarily used. May be.
For example, as shown in FIG. 20A, although a pair of openings 44B are formed in the holding portion 41B close to the base portions of the pair of plate terminals 42B, the tips of the respective plate terminals 42B are formed. Although the first male terminal member 40B in which the part is not divided and the tip part of the pair of plate-like terminals 42C are divided into two divided end parts 43C as shown in FIG. 20 (B), The second male terminal member 40C in which no opening is formed in the holding portion 41C can also be used.

複数の単電池３０を直列接続する際のように、２つのオス端子部材を互いに組み合わせる必要がなく、オス端子部材をそれぞれ単独で使用する場合には、図２０（Ａ）に示した第１のオス端子部材４０Ｂと図２０（Ｂ）に示した第２のオス端子部材４０Ｃのいずれをも用いることができる。
そして、複数の単電池３０を並列接続する際のように、２つのオス端子部材を互いに組み合わせる場合には、図２１に示されるように、第１のオス端子部材４０Ｂの板状端子４２Ｂをメス端子部材１０の第１のスロット１４および第２のスロット１７の一方に挿入した後、第１のオス端子部材４０Ｂの開口部４４Ｂに第２のオス端子部材４０Ｃの１つの分割端部４３Ｃを挿入することで、これら第１のオス端子部材４０Ｂおよび第２のオス端子部材４０Ｃを互いに組み合わせた状態で、メス端子部材１０の第１のスロット１４および第２のスロット１７にそれぞれ対応する第１のオス端子部材４０Ｂの板状端子４２Ｂおよび第２のオス端子部材４０Ｃの板状端子４２Ｃを挿入することができる。
第１のオス端子部材４０Ｂおよび第２のオス端子部材４０Ｃに対しても、図１７に示したような絶縁カバー５０で保持部４１Ｂおよび４１Ｃを覆うことにより、感電防止を行うことができる。なお、第２のオス端子部材４０Ｃの保持部４１Ｃには、開口部が形成されていないので、第２のオス端子部材４０Ｃに適用される絶縁カバーは、開口部５１を有する必要はなく、保持部４１Ｃの上面全体を覆うことが好ましい。 When the plurality of single cells 30 are connected in series, it is not necessary to combine the two male terminal members with each other, and when the male terminal members are used individually, the first terminal shown in FIG. Either the male terminal member 40B or the second male terminal member 40C shown in FIG. 20B can be used.
When two male terminal members are combined with each other as in the case of connecting a plurality of unit cells 30 in parallel, as shown in FIG. 21, the plate-like terminal 42B of the first male terminal member 40B is connected to a female. After being inserted into one of the first slot 14 and the second slot 17 of the terminal member 10, one split end 43C of the second male terminal member 40C is inserted into the opening 44B of the first male terminal member 40B. Thus, in a state where the first male terminal member 40B and the second male terminal member 40C are combined with each other, the first slot 14 and the second slot 17 corresponding to the first slot 14 and the second slot 17 of the female terminal member 10, respectively. The plate terminal 42B of the male terminal member 40B and the plate terminal 42C of the second male terminal member 40C can be inserted.
The first male terminal member 40B and the second male terminal member 40C can be protected from electric shock by covering the holding portions 41B and 41C with the insulating cover 50 as shown in FIG. In addition, since the opening part is not formed in the holding | maintenance part 41C of the 2nd male terminal member 40C, the insulating cover applied to the 2nd male terminal member 40C does not need to have the opening part 51, and hold | maintains It is preferable to cover the entire top surface of the portion 41C.

実施の形態２
図２２に、この発明の実施の形態２に係るメス端子部材６０を示す。メス端子部材６０は、単電池の正の電極および負の電極に共通して取り付けられるもので、帯状の板材の両端を互いに接続するように折り曲げて形成された周壁部６１を有している。周壁部６１は、互いに直交する２本の直線Ｌ３およびＬ４をそれぞれ中心線とする２つの矩形を接続したような断面形状を有している。 Embodiment 2
FIG. 22 shows a female terminal member 60 according to Embodiment 2 of the present invention. The female terminal member 60 is attached in common to the positive electrode and the negative electrode of the unit cell, and has a peripheral wall portion 61 formed by bending both ends of the strip-shaped plate material so as to be connected to each other. The peripheral wall portion 61 has a cross-sectional shape in which two rectangles having two straight lines L3 and L4 orthogonal to each other as the center line are connected.

直線Ｌ３を中心線とする矩形状部分の周壁部６１の上端から上方に向けて４本の第１の板バネ６２が突出形成され、これにより、直線Ｌ３に沿った直線状の第１の挿入口６３を有する第１のスロット６４が形成されている。同様に、直線Ｌ４を中心線とする矩形状部分の周壁部６１の上端から上方に向けて４本の第２の板バネ６５が突出形成され、これにより、直線Ｌ４に沿った直線状の第２の挿入口６６を有する第２のスロット６７が形成されている。
なお、第１の板バネ６２は、第１の挿入口６３を弾性的に閉じるように接点を形成し、第２の板バネ６５は、第２の挿入口６６を弾性的に閉じるように接点を形成している。
また、周壁部６１の下部には下方に延びる脚部６８が連結され、この脚部６８に取付孔６９が形成されている。 Four first leaf springs 62 are formed to project upward from the upper end of the peripheral wall portion 61 of the rectangular portion having the straight line L3 as the center line, and thereby, the first linear insertion along the straight line L3. A first slot 64 having a mouth 63 is formed. Similarly, four second leaf springs 65 project upward from the upper end of the peripheral wall portion 61 of the rectangular portion having the straight line L4 as the center line, and thereby, the linear second shape along the straight line L4 is formed. A second slot 67 having two insertion ports 66 is formed.
The first leaf spring 62 forms a contact so as to elastically close the first insertion port 63, and the second leaf spring 65 forms a contact so as to elastically close the second insertion port 66. Is forming.
A leg 68 extending downward is connected to the lower portion of the peripheral wall 61, and a mounting hole 69 is formed in the leg 68.

図２３に示されるように、第１のスロット６４の第１の挿入口６３および第２のスロット６７の第２の挿入口６６は、それぞれ直線Ｌ３およびＬ４に沿っており、互いに９０度の角度を成している。
このようなメス端子部材６０は、導電性を有する金属板７０を、図２４に示されるような形状に切り抜いた後、折り曲げ加工することで作成することができる。帯状部７１が周壁部６１を形成し、帯状部７１の下辺に接続された同一形状の一対の板状部７２が重ね合わされて脚部６８を形成し、帯状部７１の上辺に接続された８本の線状部７３から第１の板バネ６２および第２の板バネ６５が形成される。 As shown in FIG. 23, the first insertion slot 63 of the first slot 64 and the second insertion slot 66 of the second slot 67 are along straight lines L3 and L4, respectively, and are at an angle of 90 degrees to each other. Is made.
Such a female terminal member 60 can be produced by cutting a conductive metal plate 70 into a shape as shown in FIG. 24 and then bending it. The band-shaped portion 71 forms the peripheral wall portion 61, and a pair of plate-shaped portions 72 having the same shape connected to the lower side of the band-shaped portion 71 are overlapped to form a leg portion 68, and 8 connected to the upper side of the band-shaped portion 71. A first leaf spring 62 and a second leaf spring 65 are formed from the linear portion 73 of the book.

図２５および２６に、メス端子部材６０が取り付けられた単電池８０を示す。単電池８０は、厚さの薄いほぼ直方体形状の絶縁ケース８１を有し、絶縁ケース８１の内部に所定の起電力を有するセル部分が収容されている。絶縁ケース８１の上部の一端に正の電極８２、他端に負の電極８３が露出しており、これらの電極８２および８３に、それぞれメス端子部材６０が固定されている。メス端子部材６０は、第１のスロット６４および第２のスロット６７が上方を向くように、取付孔６９を利用して図示しないボルトにより取り付けられている。ここで、正の電極８２に取り付けられたメス端子部材６０も、負の電極８３に取り付けられたメス端子部材６０も、第１のスロット６４の第１の挿入口６３が、ほぼ直方体形状の絶縁ケース８１の厚さ方向に延び、第２のスロット６７の第２の挿入口６６が、絶縁ケース８１の幅方向に延びるように配置されている。このため、複数の単電池８０を絶縁ケース８１の厚さ方向または幅方向に配列したときに、第１のスロット６４の第１の挿入口６３および第２のスロット６７の第２の挿入口６６は、単電池８０の配列方向に対して０度または９０度の角度を成すこととなる。   25 and 26 show a cell 80 to which the female terminal member 60 is attached. The unit cell 80 has a substantially rectangular parallelepiped insulating case 81 having a small thickness, and a cell portion having a predetermined electromotive force is accommodated inside the insulating case 81. A positive electrode 82 is exposed at one end of the upper portion of the insulating case 81, and a negative electrode 83 is exposed at the other end. A female terminal member 60 is fixed to each of these electrodes 82 and 83. The female terminal member 60 is attached by a bolt (not shown) using an attachment hole 69 so that the first slot 64 and the second slot 67 face upward. Here, in both the female terminal member 60 attached to the positive electrode 82 and the female terminal member 60 attached to the negative electrode 83, the first insertion port 63 of the first slot 64 has a substantially rectangular parallelepiped insulation. The case 81 extends in the thickness direction, and the second insertion port 66 of the second slot 67 is arranged to extend in the width direction of the insulating case 81. For this reason, when the plurality of single cells 80 are arranged in the thickness direction or the width direction of the insulating case 81, the first insertion port 63 of the first slot 64 and the second insertion port 66 of the second slot 67. Will form an angle of 0 degrees or 90 degrees with respect to the arrangement direction of the cells 80.

絶縁ケース８１は、このように電極８２および８３にそれぞれ取り付けられたメス端子部材６０の上部を覆うように矩形状の天井部８４を有しており、この天井部８４に、双方のメス端子部材６０の第１のスロット６４に対向する開口部８５と第２のスロット６７に対向する開口部８６が形成されている。第１のスロット６４に対向する開口部８５は、絶縁ケース８１の厚さ方向すなわち天井部８４の短辺方向に沿って形成され、第２のスロット６７に対向する開口部８６は、絶縁ケース８１の幅方向すなわち天井部８４の長辺方向に沿って形成されている。また、天井部８４の長辺方向の両端部において、それぞれ、第１のスロット６４に対向する開口部８５が外側に、第２のスロット６７に対向する開口部８６が内側に配置されている。
なお、開口部８５および８６を有する天井部８４によりメス端子部材６０の上部が覆われているため、メス端子部材６０に直接接触して感電することが未然に防止されている。 The insulating case 81 has a rectangular ceiling portion 84 so as to cover the upper part of the female terminal member 60 attached to the electrodes 82 and 83 as described above. Both the female terminal members are provided on the ceiling portion 84. An opening 85 facing the 60 first slots 64 and an opening 86 facing the second slots 67 are formed. The opening 85 facing the first slot 64 is formed along the thickness direction of the insulating case 81, that is, along the short side direction of the ceiling portion 84, and the opening 86 facing the second slot 67 is formed in the insulating case 81. Are formed along the long side direction of the ceiling portion 84. In addition, at both ends of the long side direction of the ceiling portion 84, the opening 85 facing the first slot 64 is disposed outside, and the opening 86 facing the second slot 67 is disposed inside.
In addition, since the upper part of the female terminal member 60 is covered by the ceiling part 84 having the openings 85 and 86, it is possible to prevent an electric shock by directly contacting the female terminal member 60.

図２７に、メス端子部材６０に対応して使用されるオス端子部材９０の構成を示す。オス端子部材９０は、平板形状の保持部９１を有し、保持部９１の両端に、それぞれ保持部９１に対して垂直な同一方向に突出する一対の板状端子９２が形成されている。これらの板状端子９２は、互いに９０度の角度を成すように配置されている。
一対の板状端子９２の間隔は、組電池を形成するために複数の単電池８０を配列したときに、互いに隣接する単電池８０の互いに近接するメス端子部材６０の間隔となるように予め設定されている。 In FIG. 27, the structure of the male terminal member 90 used corresponding to the female terminal member 60 is shown. The male terminal member 90 has a flat plate-shaped holding portion 91, and a pair of plate-like terminals 92 that protrude in the same direction perpendicular to the holding portion 91 are formed at both ends of the holding portion 91. These plate terminals 92 are arranged so as to form an angle of 90 degrees with each other.
The interval between the pair of plate-like terminals 92 is set in advance such that when a plurality of unit cells 80 are arranged to form an assembled battery, the unit cell 80 adjacent to each other is adjacent to each other. Has been.

これにより、複数の単電池８０を配列したときに、互いに隣接する単電池８０の互いに近接する一対のメス端子部材６０の第１のスロット６４または第２のスロット６７に、オス端子部材９０の一対の板状端子９２をそれぞれ挿入することができるようになる。例えば、図２８に示されるように、オス端子部材９０の一方の板状端子９２が一方のメス端子部材６０の第１のスロット６４に挿入されると同時に、他方の板状端子９２が他方のメス端子部材６０の第２のスロット６７に挿入される。
オス端子部材９０の一対の板状端子９２は、それぞれ対応するメス端子部材６０の第１のスロット６４の第１の挿入口６３および第２のスロット６７の第２の挿入口６６に挿入され、オス端子部材９０を介して双方のメス端子部材６０が電気的に接続される。 Thus, when the plurality of unit cells 80 are arranged, the pair of male terminal members 90 is inserted into the first slot 64 or the second slot 67 of the pair of female terminal members 60 adjacent to each other in the unit cells 80 adjacent to each other. Each of the plate-like terminals 92 can be inserted. For example, as shown in FIG. 28, one plate-like terminal 92 of the male terminal member 90 is inserted into the first slot 64 of one female terminal member 60, while the other plate-like terminal 92 is inserted into the other The female terminal member 60 is inserted into the second slot 67.
The pair of plate-shaped terminals 92 of the male terminal member 90 are inserted into the first insertion port 63 of the first slot 64 and the second insertion port 66 of the second slot 67 of the corresponding female terminal member 60, respectively. Both female terminal members 60 are electrically connected via the male terminal member 90.

次に、メス端子部材６０が装着された複数の単電池８０をオス端子部材９０により接続して組電池とする方法について説明する。
まず、図２９に、４つの単電池８０ａ〜８０ｄを直列接続した組電池を示す。単電池８０ａ〜８０ｄは、それぞれ図２５および２６に示した単電池８０と同一の構造を有しており、正の電極と負の電極を交互に反対方向に向けて、互いに隣接する単電池の正の電極と負の電極が互いに近接する電極対を形成するように４つの単電池８０ａ〜８０ｄを配列する。 Next, a method of connecting a plurality of single cells 80 equipped with the female terminal member 60 by the male terminal member 90 to form an assembled battery will be described.
First, FIG. 29 shows an assembled battery in which four unit cells 80a to 80d are connected in series. The unit cells 80a to 80d have the same structure as that of the unit cell 80 shown in FIGS. 25 and 26, respectively. The unit cells 80a to 80d are adjacent to each other with the positive and negative electrodes alternately directed in opposite directions. Four unit cells 80a to 80d are arranged so that the positive electrode and the negative electrode form an electrode pair close to each other.

そして、互いに近接する複数の電極対を、交互に、オス端子部材９０を用いて接続する。すなわち、まず、単電池８０ａの正の電極と単電池８０ｂの負の電極をオス端子部材９０により接続し、単電池８０ｂの正の電極と単電池８０ｃの負の電極をオス端子部材９０により接続し、単電池８０ｃの正の電極と単電池８０ｄの負の電極をオス端子部材９０により接続する。
このとき、図２８に示すように、互いに近接する複数の電極対のうち、一方の電極に取り付けられたメス端子部材６０の第１のスロット６４に、オス端子部材９０の一方の板状端子９２が対応する単電池の絶縁ケース８１の開口部８５を介して挿入され、他方の電極に取り付けられたメス端子部材６０の第２のスロット６７に、オス端子部材９０の一対の板状端子９２が対応する単電池の絶縁ケース８１の開口部８６を介して挿入される。 A plurality of electrode pairs adjacent to each other are alternately connected using the male terminal members 90. That is, first, the positive electrode of the unit cell 80 a and the negative electrode of the unit cell 80 b are connected by the male terminal member 90, and the positive electrode of the unit cell 80 b and the negative electrode of the unit cell 80 c are connected by the male terminal member 90. Then, the positive electrode of the cell 80 c and the negative electrode of the cell 80 d are connected by the male terminal member 90.
At this time, as shown in FIG. 28, one plate-like terminal 92 of the male terminal member 90 is inserted into the first slot 64 of the female terminal member 60 attached to one of the plurality of electrode pairs adjacent to each other. A pair of plate-like terminals 92 of the male terminal member 90 is inserted into the second slot 67 of the female terminal member 60 that is inserted through the opening 85 of the corresponding cell insulation case 81 and attached to the other electrode. It is inserted through the opening 86 of the corresponding cell insulation case 81.

なお、直列接続の両端部となる、単電池８０ａの負の電極と単電池８０ｄの正の電極には、それぞれ出力取り出し用の端子部材９３が接続されている。端子部材９３も、オス端子部材９０の板状端子９２と同様の１つの板状端子を有しており、この板状端子を対応するメス端子部材６０の第１のスロット６４または第２のスロット６７に挿入することで、対応する単電池の電極に接続される。   Note that output terminal members 93 are connected to the negative electrode of the unit cell 80a and the positive electrode of the unit cell 80d, which are both ends of the series connection. The terminal member 93 also has one plate-like terminal similar to the plate-like terminal 92 of the male terminal member 90, and this plate-like terminal is the first slot 64 or the second slot of the corresponding female terminal member 60. By being inserted into 67, it is connected to the electrode of the corresponding cell.

次に、図３０に、４つの単電池８０ａ〜８０ｄを並列接続した組電池を示す。それぞれ正の電極と負の電極を同一方向に向けて、互いに隣接する単電池の正の電極同士または負の電極同士が互いに近接する電極対を形成するように４つの単電池８０ａ〜８０ｄを配列する。   Next, FIG. 30 shows an assembled battery in which four unit cells 80a to 80d are connected in parallel. Four unit cells 80a to 80d are arranged so that positive electrodes and negative electrodes are directed in the same direction, and positive electrodes of adjacent unit cells or electrode pairs in which negative electrodes are close to each other are formed. To do.

そして、互いに近接する複数の電極対を、それぞれオス端子部材９０を用いて接続する。すなわち、４つの単電池８０ａ〜８０ｄの正の電極同士をそれぞれオス端子部材９０を用いて順次接続し、４つの単電池８０ａ〜８０ｄの負の電極同士をそれぞれオス端子部材９０を用いて順次接続する。例えば、単電池８０ｂの負の電極に取り付けられたメス端子部材６０においては、隣接する単電池８０ａの負の電極との接続を行うためにオス端子部材９０の板状端子９２が第１のスロット６４に挿入され、反対方向に隣接する単電池８０ｃの負の電極との接続を行うためのオス端子部材９０の板状端子９２が第２のスロット６７に挿入される。これにより、単電池８０ｂの負の電極が隣接する単電池８０ａの負の電極および単電池８０ｃの負の電極にそれぞれ接続される。   Then, a plurality of electrode pairs adjacent to each other are connected using male terminal members 90, respectively. That is, the positive electrodes of the four unit cells 80a to 80d are sequentially connected using the male terminal member 90, and the negative electrodes of the four unit cells 80a to 80d are sequentially connected to each other using the male terminal member 90. To do. For example, in the female terminal member 60 attached to the negative electrode of the unit cell 80b, the plate-like terminal 92 of the male terminal member 90 is the first slot in order to connect to the negative electrode of the adjacent unit cell 80a. A plate-like terminal 92 of the male terminal member 90 is inserted into the second slot 67 to connect to the negative electrode of the unit cell 80 c that is inserted in the opposite direction in the opposite direction. Thereby, the negative electrode of the cell 80b is connected to the negative electrode of the adjacent cell 80a and the negative electrode of the cell 80c, respectively.

同様にして、４つの単電池８０ａ〜８０ｄの正の電極同士を順次接続すると共に負の電極同士を順次接続することで、４つの単電池８０ａ〜８０ｄを並列接続した組電池が構成される。
このように、配列される単電池８０ａ〜８０ｄのそれぞれの向きとメス端子部材６０に嵌合されるオス端子部材９０の位置および個数を変更するだけで、極めて容易に直列接続と並列接続を切り替えることができる。 Similarly, an assembled battery in which the four unit cells 80a to 80d are connected in parallel is configured by sequentially connecting the positive electrodes of the four unit cells 80a to 80d and sequentially connecting the negative electrodes to each other.
As described above, the series connection and the parallel connection can be switched very easily only by changing the orientation of each of the arranged cells 80 a to 80 d and the position and number of the male terminal members 90 fitted to the female terminal member 60. be able to.

ここで、メス端子部材６０の第１のスロット６４および第２のスロット６７は、それぞれ第１の板バネ６２および第２の板バネ６５が第１の挿入口６３および第２の挿入口６６を弾性的に閉じるように接点を形成し、これら第１の挿入口６３および第２の挿入口６６にオス端子部材９０の板状端子９２が挿入されるので、単電池８０の製造公差および複数の単電池８０の配列ズレ等に起因して、互いに近接する一対のメス端子部材６０の位置関係が縦方向、横方向および高さ方向にズレた場合であっても、そのズレを吸収して一対のメス端子部材６０にオス端子部材９０を嵌合させることができる。   Here, in the first slot 64 and the second slot 67 of the female terminal member 60, the first leaf spring 62 and the second leaf spring 65 respectively connect the first insertion port 63 and the second insertion port 66. A contact point is formed so as to be closed elastically, and the plate-like terminal 92 of the male terminal member 90 is inserted into the first insertion port 63 and the second insertion port 66. Even if the positional relationship between the pair of female terminal members 60 that are close to each other is shifted in the vertical direction, the horizontal direction, and the height direction due to the alignment shift of the unit cells 80, the pair is absorbed and absorbed. The male terminal member 90 can be fitted to the female terminal member 60.

例えば、図３１に模式的に示されるように、一対のメス端子部材６０が、縦方向にズレ量ΔＤだけズレた場合でも、また、横方向にズレ量ΔＥだけズレた場合でも、メス端子部材６０の第１のスロット６４または第２のスロット６７に対するオス端子部材９０の板状端子９２の挿入位置を調整することで、オス端子部材９０は一対のメス端子部材６０に嵌合されることとなる。   For example, as schematically shown in FIG. 31, even if the pair of female terminal members 60 are displaced by a displacement amount ΔD in the vertical direction or when they are displaced by a displacement amount ΔE in the horizontal direction, The male terminal member 90 is fitted into the pair of female terminal members 60 by adjusting the insertion position of the plate-like terminal 92 of the male terminal member 90 with respect to the first slot 64 or the second slot 67 of 60; Become.

さらに、図３２に示されるように、一対のメス端子部材６０が、高さ方向にズレ量ΔＨだけズレた場合であっても、メス端子部材６０の第１のスロット６４または第２のスロット６７に対するオス端子部材９０の板状端子９２の挿入量が変化するだけで、オス端子部材９０を一対のメス端子部材６０に嵌合させることができる。
このため、単電池８０の製造公差および複数の単電池８０の配列ズレ等に起因して、近接する一対のメス端子部材６０の位置関係にズレが生じた場合でも、そのズレを矯正することなく、容易に組電池を形成することが可能となる。 Furthermore, as shown in FIG. 32, even when the pair of female terminal members 60 are displaced by a deviation amount ΔH in the height direction, the first slot 64 or the second slot 67 of the female terminal member 60. The male terminal member 90 can be fitted to the pair of female terminal members 60 only by changing the amount of insertion of the plate-like terminal 92 of the male terminal member 90 relative to the male terminal member 90.
For this reason, even when the positional relationship between the pair of female terminal members 60 adjacent to each other due to the manufacturing tolerance of the unit cells 80 and the misalignment of the plurality of unit cells 80 occurs, the deviation is not corrected. Thus, an assembled battery can be easily formed.

なお、この実施の形態２で用いたオス端子部材９０に対しても、図１７に示したような絶縁カバーを被せる、あるいは、保持部９１の表面上に絶縁膜を形成することにより、組電池を形成した後に、オス端子部材９０の導電部分に直接接触して感電することを防止することができる。   The male terminal member 90 used in the second embodiment is also covered with an insulating cover as shown in FIG. 17 or an insulating film is formed on the surface of the holding portion 91 to thereby provide an assembled battery. After forming, it is possible to prevent an electric shock by directly contacting the conductive portion of the male terminal member 90.
