次に、他の構造の端子を備えたバスバモジュール11について説明する。
図5は、他の構造の端子の斜視図である。図6は、他の構造の端子を備えたバスバモジュールの幅方向に沿う断面図である。
Next, a bus module 11 having terminals having another structure will be described.
FIG. 5 is a perspective view of terminals having other structures. FIG. 6 is a cross-sectional view taken along the width direction of a bus bar module having terminals having other structures.

図5及び図6に示すように、この端子51は、バスバ接続部31の一辺に、一対の圧接刃52を有する電線接続部54を備えている。圧接刃52は、電圧検知線19が圧入されるスリット52aを有しており、バスバ接続部31の一辺に沿って互いに間隔をあけて配置されている。この端子51では、圧接刃52のスリット52aに電圧検知線19を圧入することで、電圧検知線19の被覆が切られ、内部の導体がスリット52aに食い込む。これにより、端子51が電圧検知線19の導体と電気的に接続される。 As shown in FIGS. 5 and 6, the terminal 51 includes an electric wire connecting portion 54 having a pair of pressure welding blades 52 on one side of the bus bar connecting portion 31. The pressure welding blade 52 has a slit 52a into which the voltage detection line 19 is press-fitted, and is arranged at a distance from each other along one side of the bus bar connection portion 31. At this terminal 51, the voltage detection line 19 is press-fitted into the slit 52a of the pressure welding blade 52 to cut the coating of the voltage detection line 19, and the internal conductor bites into the slit 52a. As a result, the terminal 51 is electrically connected to the conductor of the voltage detection line 19.

図6に示すように、端子51を用いる場合、バスバモジュール11のバスバ収容部20に端子51を収容し、電極12aの位置に対応するように、端子51の孔部31aとバスバ16の孔部16aとを一致させてバスバ16に固定する。このとき、電線接続部54の圧接刃52が電圧検知線19の引き出し方向に沿って配列されるように、端子51を、電線接続部54が側方へ向くように固定する。そして、この端子51の電線接続部54の圧接刃52に電圧検知線19を圧接させて接続し、電圧検知線19を上記と同じ手順により電線配索体21から引き出した後に、端子51を電池12の電極12aに締結する。 As shown in FIG. 6, when the terminal 51 is used, the terminal 51 is housed in the bus bar accommodating portion 20 of the bus bar module 11, and the hole portion 31a of the terminal 51 and the hole portion of the bus bar 16 correspond to the positions of the electrodes 12a. It is fixed to the bus bar 16 so as to match with 16a. At this time, the terminals 51 are fixed so that the electric wire connecting portion 54 faces sideways so that the pressure welding blades 52 of the electric wire connecting portion 54 are arranged along the drawing direction of the voltage detection line 19. Then, the voltage detection line 19 is pressure-welded to the pressure welding blade 52 of the wire connection portion 54 of the terminal 51 to be connected, and the voltage detection line 19 is pulled out from the wire wiring body 21 by the same procedure as described above, and then the terminal 51 is connected to the battery. It is fastened to the electrode 12a of 12.

このように、圧接刃52を有する電線接続部54を備えた端子51を用いれば、電圧検知線19を接続する前に端子51をバスバモジュール11のバスバ収容部20に収容し、電池12の電極12aに対応する位置に予め固定しておくことができる。 In this way, if the terminal 51 having the electric wire connecting portion 54 having the pressure welding blade 52 is used, the terminal 51 is accommodated in the bus bar accommodating portion 20 of the bus bar module 11 before the voltage detection line 19 is connected, and the electrode of the battery 12 is used. It can be fixed in advance at the position corresponding to 12a.

次に、本実施形態に係る電線配索方法について説明する。

FIG. 7 is a series of work process diagrams showing a method of arranging the voltage detection line 19 to the bus module 11 shown in FIG. 2, and FIGS. 7 (a) to 7 (g) are in each work. It is a schematic plan view. Here, the bus bar connection portion 31 of the terminal 17 is shown as a substantially circular shape. Further, a terminal 26 inserted into the cavity in the connector 18 is crimped to the end portion (the other end 19b) of the voltage detection line 19 on the connector 18 side.

図7(a)に示すように、リール71から電圧検知線19となる電線を引き出し、その一端19aを末端加工して端子17に圧着した後、電線把持具41に保持させる。電線把持具41は、電線を挟持可能な複数のスリットを有する長尺の保持具である。 As shown in FIG. 7A, an electric wire serving as a voltage detection line 19 is pulled out from the reel 71, one end 19a thereof is end-processed, crimped to the terminal 17, and then held by the electric wire gripper 41. The electric wire gripper 41 is a long holder having a plurality of slits capable of sandwiching the electric wire.

図7(b)に示すように、リール71から電圧検知線19を切断し、電圧検知線19の他端19bを末端加工して端子26に圧着した後、電線把持具41に保持させる。これを、バスバモジュール11に配索するすべての電圧検知線19について繰り返す。 As shown in FIG. 7B, the voltage detection line 19 is cut from the reel 71, the other end 19b of the voltage detection line 19 is end-processed, crimped to the terminal 26, and then held by the electric wire gripper 41. This is repeated for all the voltage detection lines 19 arranged in the bus module 11.

図7(c)に示すように、すべての電圧検知線19を保持させた電線把持具41を作業台72にセットし、すべての電圧検知線19の他端19b側の端子26をコネクタ18の各キャビティに挿入する。 As shown in FIG. 7C, the electric wire gripper 41 holding all the voltage detection lines 19 is set on the workbench 72, and the terminal 26 on the other end 19b side of all the voltage detection lines 19 is connected to the connector 18. Insert into each cavity.

図7(d)に示すように、バスバモジュール11を作業台72にセットする。また、作業台72上には、コネクタ18をバスバ収容部20の配列方向にスライド可能な溝あるいはレール等の案内機構が形成されており、コネクタ18をこの案内機構の配索作業開始位置にセットする。この例では、バスバモジュール11の右端部にコネクタ18をセットしている。そして、1本目(最も右側)の電圧検知線19の一端19aを電線把持具41から取り外し、その端子17をバスバ16における電池12の1番目(最も右側)の電極12aに対応する位置に、バスバ16の孔部16aと端子17の孔部31aとが重なった状態で固定する。 As shown in FIG. 7D, the bus module 11 is set on the workbench 72. Further, a guide mechanism such as a groove or a rail that allows the connector 18 to slide in the arrangement direction of the bus bar accommodating portion 20 is formed on the workbench 72, and the connector 18 is set at the wiring work start position of this guide mechanism. To do. In this example, the connector 18 is set at the right end of the bus module 11. Then, one end 19a of the first (rightmost) voltage detection line 19 is removed from the electric wire gripper 41, and the terminal 17 is placed at a position corresponding to the first (rightmost) electrode 12a of the battery 12 in the bus bar 16. The hole 16a of 16 and the hole 31a of the terminal 17 are fixed in an overlapping state.

図7(e)に示すように、コネクタ18を次の位置(一つ左側の電極12aの位置)に移動させ、次の電圧検知線19について同じ作業を順次繰り返す。このとき、電線配索部22の開口部25を開けた状態としておく。そして、各電圧検知線19を、電線配索体21の導入スリット27へ通し、電線配索部22内に導入する。このようにすると、各導入スリット27に通された各電圧検知線19が電線配索部22を通り、バスバ収容部20と反対側である電圧検知線19の引き出し方向前方側の開口部25から引き出された状態とされる。 As shown in FIG. 7E, the connector 18 is moved to the next position (the position of the electrode 12a on the left side), and the same operation is sequentially repeated for the next voltage detection line 19. At this time, the opening 25 of the electric wire wiring portion 22 is left open. Then, each voltage detection line 19 is passed through the introduction slit 27 of the electric wire wiring body 21 and introduced into the electric wire wiring portion 22. In this way, each voltage detection line 19 passed through each introduction slit 27 passes through the electric wire distribution portion 22 and is from the opening 25 on the front side in the pull-out direction of the voltage detection line 19 on the opposite side of the bus bar accommodating portion 20. It is considered to be in the pulled out state.

図7(f)に示すように、コネクタ18をバスバモジュール11の一端側(左端側)へ引きながら開口部25から引き出された各電圧検知線19を電線配索部22内に収容させる。 As shown in FIG. 7 (f), while pulling the connector 18 toward one end side (left end side) of the bus module 11, each voltage detection line 19 drawn from the opening 25 is accommodated in the electric wire wiring portion 22.

図7(g)に示すように、蓋体28を回動させて電線配索部22の開口部25に被せて閉塞させる。その後、バスバモジュール11が電池集合体13に重ねて取り付けられた状態で端子17を電池の電極12aに締結する。 As shown in FIG. 7 (g), the lid 28 is rotated to cover the opening 25 of the electric wire wiring portion 22 and close the lid 28. After that, the terminal 17 is fastened to the electrode 12a of the battery in a state where the bus module 11 is mounted on the battery assembly 13 in an overlapping manner.

上記一連の作業によって、電源装置14に装着されたバスバモジュール11には、その電線配索体21に、端子17が接続された電圧検知線19が収容される。 Through the above series of operations, the bus bar module 11 mounted on the power supply device 14 accommodates the voltage detection line 19 to which the terminal 17 is connected to the electric wire wiring body 21.

以上、説明したように、本実施形態の電線配索方法によれば、電圧検知線19の両端19a、19bにそれぞれ端子17、26が圧着される構成において、電圧検知線19の他端19b側の端子26をコネクタ18に挿入した後、コネクタ18を配索作業開始位置にセットし、そのコネクタ18を電池12の電極12aに応じた位置に順次移動させて、各電極12aに対応する位置に各電圧検知線19の一端19aを固定していくことにより、電圧検知線19の配索作業を容易に行うことができる。したがって、バスバモジュール11への電圧検知線19の配索作業性を向上させることができる。 As described above, according to the wire routing method of the present embodiment, the terminals 17 and 26 are crimped to both ends 19a and 19b of the voltage detection line 19, respectively, on the other end 19b side of the voltage detection line 19. After inserting the terminal 26 of the above into the connector 18, the connector 18 is set at the line arrangement work start position, and the connector 18 is sequentially moved to a position corresponding to the electrode 12a of the battery 12 to a position corresponding to each electrode 12a. By fixing one end 19a of each voltage detection line 19, the wiring work of the voltage detection line 19 can be easily performed. Therefore, the workability of allocating the voltage detection line 19 to the bus module 11 can be improved.

また、本実施形態によれば、バスバモジュール11の電線配索体21の電線配索部22が、電圧検知線19の引き出し方向前方側に開口部25を有するので、電池12の電極12a側から電線配索部22に導入され、電線配索部22の開口部25から引き出された電圧検知線19をまとめて屈曲させて電線配索部22内へ入れることができる。これにより、開口部が電圧検知線の引き出し方向と直交する上方に形成されている場合と比較し、電圧検知線19を束ねて電線配索部22内に一括して収容させ、バスバ収容部20の配列方向に配索させることができる。したがって、電線配索体21への電圧検知線19の配索作業性をより向上させることができる。 Further, according to the present embodiment, since the electric wire wiring portion 22 of the electric wire wiring body 21 of the bus module 11 has an opening 25 on the front side in the lead-out direction of the voltage detection line 19, from the electrode 12a side of the battery 12. The voltage detection lines 19 introduced into the electric wire arranging portion 22 and drawn from the opening 25 of the electric wire arranging portion 22 can be collectively bent and put into the electric wire arranging portion 22. As a result, as compared with the case where the opening is formed in the upper direction orthogonal to the drawing direction of the voltage detection line, the voltage detection line 19 is bundled and housed in the electric wire wiring part 22 collectively, and the bus bar accommodating part 20 Can be arranged in the direction of arrangement. Therefore, the workability of arranging the voltage detection line 19 to the electric wire allocating body 21 can be further improved.

また、上面板部24に、電極12aに接続されて引き出された電圧検知線19の引き出し方向に沿って電線配索部22と連通する導入スリット27が形成されているので、電極12a側から引き出された電圧検知線19を、導入スリット27から電線配索部22内へ容易に導入させることができ、電圧検知線19の配索作業性をさらに向上させることができる。 Further, since the upper surface plate portion 24 is formed with an introduction slit 27 that communicates with the electric wire wiring portion 22 along the drawing direction of the voltage detection line 19 that is connected to the electrode 12a and pulled out, it is pulled out from the electrode 12a side. The voltage detection line 19 can be easily introduced into the electric wire wiring portion 22 from the introduction slit 27, and the wiring workability of the voltage detection line 19 can be further improved.

図8(b)に示すように、リール71から電圧検知線19を切断し、電圧検知線19の他端19bを末端加工した後、端子26を圧着し、電線把持具41に保持させる。これを、バスバモジュール11に配索するすべての電圧検知線19について繰り返す。 As shown in FIG. 8B, the voltage detection line 19 is cut from the reel 71, the other end 19b of the voltage detection line 19 is end-processed, and then the terminal 26 is crimped and held by the electric wire gripper 41. This is repeated for all the voltage detection lines 19 arranged in the bus module 11.

図8(c)に示すように、すべての電圧検知線19を保持させた電線把持具41を作業台72にセットし、すべての電圧検知線19の他端19bに圧着された端子26をコネクタ18内の各キャビティに挿入する。 As shown in FIG. 8C, the electric wire gripper 41 holding all the voltage detection lines 19 is set on the workbench 72, and the terminal 26 crimped to the other end 19b of all the voltage detection lines 19 is connected to the connector. Insert into each cavity within 18.

図8(d)に示すように、コネクタ18を案内機構に沿って1番目(もっとも右側)の端子51の位置に移動させ、電線把持具41に保持された電圧検知線19の一端19aを取り出し、端子51に圧接する。 As shown in FIG. 8D, the connector 18 is moved to the position of the first (rightmost) terminal 51 along the guide mechanism, and one end 19a of the voltage detection line 19 held by the electric wire gripper 41 is taken out. , Press-contact with the terminal 51.

図8(e)に示すように、コネクタ18を次の位置(一つ左側の端子51の位置)に移動させ、次の電圧検知線19について同じ作業を順次繰り返す。 As shown in FIG. 8E, the connector 18 is moved to the next position (the position of the terminal 51 on the left side), and the same operation is sequentially repeated for the next voltage detection line 19.

その後、図8(f)〜(g)に示すように、図7(f)〜(g)と同様の作業を行う。 After that, as shown in FIGS. 8 (f) to (g), the same operation as in FIGS. 7 (f) to (g) is performed.

上記一連の作業によって、電源装置14に装着されたバスバモジュール11には、その電線配索体21に、端子17が接続された電圧検知線19が収容される。 Through the above series of operations, the bus bar module 11 mounted on the power supply device 14 accommodates the voltage detection line 19 to which the terminal 17 is connected to the electric wire wiring body 21.

以上、説明したように、本実施形態の電線配索方法によれば、電圧検知線19の一端19aに端子17が圧着され、他端26がコネクタ18内の端子に圧接される構成において、電圧検知線19の他端19bをコネクタ18内の電極に接続した後、コネクタ18を配索作業開始位置にセットし、そのコネクタ18を電池12の電極12aに応じた位置に順次移動させて、各電極12aに対応する位置に各電圧検知線19の一端19aを固定していくことにより、電圧検知線19の配索作業を容易に行うことができる。したがって、バスバモジュール11への電圧検知線19の配索作業性を向上させることができる。 As described above, according to the wire routing method of the present embodiment, the voltage is applied in a configuration in which the terminal 17 is crimped to one end 19a of the voltage detection line 19 and the other end 26 is pressed against the terminal in the connector 18. After connecting the other end 19b of the detection line 19 to the electrode in the connector 18, the connector 18 is set at the wiring work start position, and the connector 18 is sequentially moved to a position corresponding to the electrode 12a of the battery 12, and each of them is By fixing one end 19a of each voltage detection line 19 at a position corresponding to the electrode 12a, the wiring work of the voltage detection line 19 can be easily performed. Therefore, the workability of allocating the voltage detection line 19 to the bus module 11 can be improved.

図9は、図6に示すバスバモジュール11に電圧検知線19を配索する方法を示す一連の作業工程図であって、図9(a)から図9(f)は、それぞれの各作業における概略平面図である。なお、コネクタ18には、図5に示す端子51と同様の圧接刃52を有する端子が設けられている。 FIG. 9 is a series of work process diagrams showing a method of arranging the voltage detection line 19 to the bus module 11 shown in FIG. 6, and FIGS. 9 (a) to 9 (f) show each work. It is a schematic plan view. The connector 18 is provided with a terminal having a pressure welding blade 52 similar to the terminal 51 shown in FIG.

図9(a)に示すように、全ての端子51をそれぞれバスバ16における電池12の電極12aに対応する位置に、端子51の孔部31aとバスバ16の孔部16aとが重なる状態で固定する。 As shown in FIG. 9A, all the terminals 51 are fixed at positions corresponding to the electrodes 12a of the battery 12 in the bus bar 16 in a state where the hole 31a of the terminal 51 and the hole 16a of the bus bar 16 overlap each other. ..

図9(b)に示すように、リール71から電圧検知線19となる電線を引き出し、その一端19aを末端加工して、電源装置14の1番目(最も右側)の端子51の圧接刃52に圧接させる。その後、リール71から電圧検知線19を切断し、その他端19bを端末加工する。 As shown in FIG. 9B, an electric wire serving as a voltage detection line 19 is pulled out from the reel 71, one end 19a thereof is end-processed, and the pressure welding blade 52 of the first (rightmost) terminal 51 of the power supply device 14 is formed. Press it. After that, the voltage detection line 19 is cut from the reel 71, and the other end 19b is terminally processed.

図9(c)に示すように、導入スリット27に沿って電圧検知線19を引き出し、その他端19bをコネクタ18内の端子に圧接させる。なお、この時点ではコネクタ18は上側ハウジングと下側ハウジングとに2分割されており、すべての電圧検知線19の他端19bが端子に圧接されたなら、上側ハウジングと下側ハウジングとを嵌合する。なお、上側ハウジングと下側ハウジングとを嵌合することによって電圧検知線19の他端19bが圧接されるようにコネクタ18を形成してもよい。 As shown in FIG. 9C, the voltage detection line 19 is pulled out along the introduction slit 27, and the other end 19b is pressed against the terminal in the connector 18. At this point, the connector 18 is divided into an upper housing and a lower housing, and if the other ends 19b of all the voltage detection lines 19 are pressed against the terminals, the upper housing and the lower housing are fitted. To do. The connector 18 may be formed so that the other end 19b of the voltage detection line 19 is pressure-contacted by fitting the upper housing and the lower housing.

図9(d)に示すように、コネクタ18を上記案内機構に沿って次の位置(一つ左側の電極12aの位置)に移動させ、次の電圧検知線19について同じ作業を順次繰り返す。このとき、電線配索部22の開口部25を開けた状態としておく。そして、各電圧検知線19を、電線配索体21の導入スリット27へ通し、電線配索部22内に導入する。このようにすると、各導入スリット27に通された各電圧検知線19が電線配索部22を通り、バスバ収容部20と反対側である電圧検知線19の引き出し方向前方側の開口部25から引き出された状態とされる。 As shown in FIG. 9D, the connector 18 is moved to the next position (the position of the electrode 12a on the left side) along the guide mechanism, and the same operation is sequentially repeated for the next voltage detection line 19. At this time, the opening 25 of the electric wire wiring portion 22 is left open. Then, each voltage detection line 19 is passed through the introduction slit 27 of the electric wire wiring body 21 and introduced into the electric wire wiring portion 22. In this way, each voltage detection line 19 passed through each introduction slit 27 passes through the electric wire distribution portion 22 and is from the opening 25 on the front side in the pull-out direction of the voltage detection line 19 on the opposite side of the bus bar accommodating portion 20. It is considered to be in the pulled out state.

その後、図9(e)、(f)に示すように、図7(f)、(g)と同様の作業を行う。 After that, as shown in FIGS. 9 (e) and 9 (f), the same operation as in FIGS. 7 (f) and 7 (g) is performed.

上記一連の作業によって、電源装置14に装着されたバスバモジュール11には、その電線配索体21に、端子17が接続された電圧検知線19が収容される。 Through the above series of operations, the bus bar module 11 mounted on the power supply device 14 accommodates the voltage detection line 19 to which the terminal 17 is connected to the electric wire wiring body 21.

以上、説明したように、本実施形態の電線配索方法によれば、電圧検知線19の両端19a、19bがそれぞれ電池12側の端子51とコネクタ18側の端子に圧接される構成において、電圧検知線19の一端19aを電池12側の端子51に接続し、他端19bをコネクタ18側の端子に接続する作業を、各電圧検知線19の引き出し方向の延長線上にコネクタ18を順次移動させて容易に行うことができる。したがって、バスバモジュール11への電圧検知線19の配索作業性を向上させることができる。 As described above, according to the electric wire wiring method of the present embodiment, the voltage is set so that both ends 19a and 19b of the voltage detection line 19 are pressed against the terminal 51 on the battery 12 side and the terminal on the connector 18 side, respectively. The work of connecting one end 19a of the detection line 19 to the terminal 51 on the battery 12 side and connecting the other end 19b to the terminal on the connector 18 side is performed by sequentially moving the connector 18 on an extension line in the lead-out direction of each voltage detection line 19. It can be done easily. Therefore, the workability of allocating the voltage detection line 19 to the bus module 11 can be improved.

なお、以上の説明では、端子51を、電線接続部54が側方へ向くように固定しているが、電線接続部54の位置を、電線配索体21に対し電極12aよりも離隔した位置であり、かつ、電圧検知線19を引き出し方向(導入スリット27が延伸する方向)と異なる向きに圧接してもよい。 In the above description, the terminal 51 is fixed so that the electric wire connecting portion 54 faces sideways, but the position of the electric wire connecting portion 54 is separated from the electric wire wiring body 21 by the electrode 12a. In addition, the voltage detection line 19 may be pressure-welded in a direction different from the drawing direction (the direction in which the introduction slit 27 extends).

これにより、電線接続部54と導入スリット27との間に配索される電圧検知線19にゆとりをもたせることができ、結果として、電圧検知線19に対し張力が印加された際に、電線接続部54に張力が急激に加わることを抑制できる。特に、電線接続部54の位置を電線配索体21から離れた側にすることによりバスバ収容部20内で電圧検知線19が引き回されるので、片持ちのリブなどの保持部により電圧検知線19を保持すると、電線接続部54への急激な張力の印加をより一層低減できる。また、電圧検知線19をバスバ収容部20内で、電線接続部54に接続された向きから引き出し方向(導入スリット27が延伸する方向)に屈曲するように引き回し、当該保持部により電圧検知線19の屈曲が保たれるように保持すると、電線接続部54への急激な張力の印加を確実に低減できる。なお、電線接続部54は、電線配索体21に対し電極12aと反対側に位置し、電圧検知線19が引き出し方向に対して90°となるよう電圧検知線19を圧接すると最適であるが、同様の効果を得られる範囲であれば、引き出し方向に対して90°以下、あるいは90°以上となるよう電圧検知線19を圧接してもよい。また、電圧検知線19が端子に圧接される場合のみならず、圧着や他の方法により端子に接続される場合においても、電圧検知線19が接続される向きを引き出し方向(導入スリット27が延伸する方向)と異ならせてもよい。 As a result, the voltage detection line 19 arranged between the electric wire connection portion 54 and the introduction slit 27 can be provided with a margin, and as a result, when tension is applied to the voltage detection line 19, the electric wire is connected. It is possible to prevent a sudden application of tension to the portion 54. In particular, since the voltage detection line 19 is routed in the bus bar accommodating portion 20 by setting the position of the electric wire connecting portion 54 to the side away from the electric wire wiring body 21, the voltage is detected by the holding portion such as the cantilever rib. When the wire 19 is held, the application of abrupt tension to the electric wire connecting portion 54 can be further reduced. Further, the voltage detection line 19 is routed in the bus bar accommodating portion 20 so as to bend from the direction connected to the electric wire connecting portion 54 in the pull-out direction (the direction in which the introduction slit 27 extends), and the voltage detection line 19 is routed by the holding portion. If the bending of the wire is maintained so as to be maintained, the application of abrupt tension to the wire connecting portion 54 can be reliably reduced. It is optimal that the electric wire connecting portion 54 is located on the side opposite to the electrode 12a with respect to the electric wire wiring body 21, and the voltage detecting line 19 is pressed against the electric wire wiring body 21 so that the voltage detecting line 19 is 90 ° with respect to the drawing direction. As long as the same effect can be obtained, the voltage detection line 19 may be pressure-welded so as to be 90 ° or less or 90 ° or more with respect to the drawing direction. Further, not only when the voltage detection line 19 is pressed against the terminal, but also when the voltage detection line 19 is connected to the terminal by crimping or other methods, the direction in which the voltage detection line 19 is connected is drawn out (the introduction slit 27 is extended). It may be different from the direction in which it is performed.

なお、上記実施形態では、電圧検知線19を電線配索部22に収容させて電線配索体21の一端から引き出したが、電圧検知線19を電線配索部22に収容させて電線配索体21の長さ方向の中央から引き出しても良い。ここで、電線配索体21の長さ方向の中央から電圧検知線19を引き出す場合について説明する。 In the above embodiment, the voltage detection line 19 is housed in the wire line 22 and pulled out from one end of the wire liner 21, but the voltage detection line 19 is housed in the wire line 22 and the wire line is laid. It may be pulled out from the center of the body 21 in the length direction. Here, a case where the voltage detection line 19 is pulled out from the center in the length direction of the electric wire wiring body 21 will be described.

図10は、変形例に係るバスバモジュールへの電圧検知線の配索手順を説明する図であって、図10(a)及び図10(b)はそれぞれ各作業における概略平面図である。 FIG. 10 is a diagram for explaining the procedure for arranging the voltage detection line to the bus module according to the modified example, and FIGS. 10 (a) and 10 (b) are schematic plan views in each operation.

図10(a)に示すように、このバスバモジュール11は、電線配索体21の長手方向の中央部分において、蓋体28がない電線引出部45を備えている。 As shown in FIG. 10A, the bus bar module 11 includes a wire lead-out portion 45 without a lid 28 at a central portion in the longitudinal direction of the wire routing body 21.

このバスバモジュール11に対して電圧検知線19を配索する場合も、図7(a)から図7(e)の一連の作業を実施する。その結果、図7(e)に示すように、各導入スリット27に通された各電圧検知線19が電線配索部22を通り、バスバ収容部20と反対側である電圧検知線19の引き出し方向前方側の開口部25から引き出された状態とされる。 When allocating the voltage detection line 19 to the bus module 11, the series of operations shown in FIGS. 7 (a) to 7 (e) is carried out. As a result, as shown in FIG. 7 (e), each voltage detection line 19 passed through each introduction slit 27 passes through the electric wire distribution portion 22 and draws out the voltage detection line 19 on the opposite side of the bus bar accommodating portion 20. It is in a state of being pulled out from the opening 25 on the front side in the direction.

次に、図10(a)に示すように、コネクタ18を電線配索体21の長手方向の中央に配置させて開口部25から引き出された各電圧検知線19を電線配索部22内に収容させる。そして、電圧検知線19を電線配索体21の中央で束ねてテープやバンドなどの付属部材46で固定する。このとき、バンドからなる付属部材46を電圧検知線19の束のコネクタ18寄りに装着しておき、この付属部材46を電線配索体21側へスライドさせるのが好ましい。このようにすると、付属部材46の電線配索体21側へのスライドによって電圧検知線19の結束箇所が電線配索体21側へ移動し、これにより、各電圧検知線19が電線配索部22内に円滑に収容される。 Next, as shown in FIG. 10 (a), the connector 18 is arranged at the center of the electric wire wiring body 21 in the longitudinal direction, and each voltage detection line 19 drawn from the opening 25 is placed in the electric wire wiring portion 22. Contain. Then, the voltage detection line 19 is bundled at the center of the electric wire wiring body 21 and fixed with an accessory member 46 such as a tape or a band. At this time, it is preferable to attach the accessory member 46 made of a band closer to the connector 18 of the bundle of the voltage detection lines 19 and slide the accessory member 46 toward the wire liner 21 side. In this way, the binding portion of the voltage detection line 19 moves to the wire liner 21 side by sliding the accessory member 46 toward the wire liner 21 side, whereby each voltage detection line 19 moves to the wire liner portion 21. It is smoothly housed in 22.

その後、図10(b)に示すように、蓋体28を回動させて電線配索部22の開口部25に被せて閉塞させる。その後、端子17を電池12の電極12aに締結する。 After that, as shown in FIG. 10B, the lid 28 is rotated to cover the opening 25 of the electric wire wiring portion 22 and close the lid 28. After that, the terminal 17 is fastened to the electrode 12a of the battery 12.

上記作業によって、バスバモジュール11には、その電線配索体21に電圧検知線19が収容され、その電圧検知線19の束が電線配索体21の長手方向の中央から引き出された状態とされる。
なお、図7〜図9に示した電線配索方法においても、図10に示した電線配索方法と同様に、電圧検知線19の束を電線配索体21の長手方向の中央から引き出すようにしてもよい。また、いずれの電線配索方法においても、長手方向の中央からずれた任意の箇所から電圧検知線19の束を引き出すようにしてもよい。
By the above work, the voltage detection line 19 is housed in the electric wire wiring body 21 of the bus bar module 11, and the bundle of the voltage detecting lines 19 is pulled out from the center of the electric wire wiring body 21 in the longitudinal direction. Ru.
In the electric wire arranging method shown in FIGS. 7 to 9, similarly to the electric wire arranging method shown in FIG. 10, the bundle of the voltage detection lines 19 is pulled out from the center of the electric wire allocating body 21 in the longitudinal direction. It may be. Further, in any of the electric wire arranging methods, the bundle of the voltage detection lines 19 may be pulled out from an arbitrary position deviated from the center in the longitudinal direction.

次に、別の実施形態のバスバモジュール61について説明する。図11は、別の実施形態に係るバスバモジュール61の概略平面図である。 Next, the bus module 61 of another embodiment will be described. FIG. 11 is a schematic plan view of the bus module 61 according to another embodiment.

図11に示すように、バスバモジュール61の電線配索体21は、下面板部23を備えている。下面板部23には、電池の電極から引き出された電圧検知線19を引き出し方向から所望の方向にガイドするガイド突起66が形成されている。
なお、図10においては、ガイド突起66が円柱状の部材により構成された場合について示しているが、楕円状や円弧状であってもよい。また、ガイド突起66を、下面板部23側の断面半径が小さく、上に行くほど断面半径が大きくなる逆円錐形状にすると、電圧検知線19を所望の方向にまとめて屈曲させた際に、電圧検知線19が下面板部23から浮きあがることを抑制できる。また、図11においては、複数のガイド突起66を、電線引き出し方向に対しそれぞれ異なる位置に設置しているが、複数のガイド突起66を、バスバ収容部20の配列方向と平行に配列してもよい。
As shown in FIG. 11, the electric wire wiring body 21 of the bus module 61 includes a lower surface plate portion 23. The bottom plate portion 23 is formed with a guide protrusion 66 that guides the voltage detection line 19 drawn from the electrode of the battery in a desired direction from the drawing direction.
Although FIG. 10 shows a case where the guide protrusion 66 is composed of a columnar member, it may have an elliptical shape or an arc shape. Further, if the guide protrusion 66 has an inverted conical shape in which the radius of gyration on the lower surface plate portion 23 side is small and the radius of gyration increases toward the top, when the voltage detection lines 19 are collectively bent in a desired direction, It is possible to prevent the voltage detection line 19 from rising from the bottom plate portion 23. Further, in FIG. 11, although the plurality of guide protrusions 66 are installed at different positions with respect to the wire lead-out direction, the plurality of guide protrusions 66 may be arranged in parallel with the arrangement direction of the bus bar accommodating portion 20. Good.

また、図11に示すバスバモジュール61において、図12に示すように、電圧検知線19が配索されている箇所に、ヒンジカバー構造の上面板部73を設けてもよい。図12の例では、上面板部73が電圧検知線19に対して部分的に設けられているが、全面的に設けられても良い。 Further, in the bus module 61 shown in FIG. 11, as shown in FIG. 12, a top plate portion 73 having a hinge cover structure may be provided at a position where the voltage detection line 19 is arranged. In the example of FIG. 12, the top plate portion 73 is partially provided with respect to the voltage detection line 19, but may be provided entirely.
