(1) a plurality of bus bars that electrically connect each battery of a battery assembly composed of a plurality of batteries;
A plurality of electric wires electrically connected to each of the batteries via the plurality of bus bars;

thing.
(3) A bus bar module configured as one of the above (1) and (2),

thing.
(4) In a power supply device comprising: a battery assembly composed of a plurality of batteries; and a bus bar module that is attached to the battery assembly and is electrically connected to each other.
The bus bar module has a bus bar module having any one of the constitutions (1) to (3).
　ところで、電線配索体に電線を配索する際に、電線配索溝部に配索された電線を底壁から斜めに或いは垂直に引き出して固定することを目的として、当該電線を、電線導出部の第１片部に対して第１の向きに所定の角度まで回動させた状態の第２片部に沿って引き出し、当該所定の角度で傾いた状態の第２片部にタイラップ等の固定部材によって固定する場合がある。このように固定した場合、電線の張力等によって、当該第２片部に、当該第１の向きとは逆向きの第２の向きに回動させようとする力が作用する虞がある。このために、第２片部が第１片部に対して回動自在な状態で当該第２片部に電線が固定されている場合には、第２片部が上記所定の角度から第２の向きに回動してしまい、電線を所望の角度で引き出すことができず、配索経路を確実に規制できない虞があった。
　これに対して、上記（１）の構成のバスバモジュールにおける電線配索体では、第２片部が第１片部に対して第１の向きに回動することにより、係止片が係合孔に進入して、係止片の側方に突出した係止突起が係合孔の縁部に引っ掛かっており、これにより、第２片部の第１の向きとは逆向きの第２の向きへの回動が規制されている。このため、上記（１）の構成のバスバモジュールにおける電線配索体では、第２片部が第２の向きに回動し難い。したがって、電線を電線導出部に沿って引き出して第２片部に固定した場合に、電線の張力等により第２片部が第２の向きに回動してしまうことが防止されるので、電線を所望の角度で引き出すことができ易い。このため、上記（１）の構成のバスバモジュールによれば、配索経路の規制における確実性を向上したバスバモジュールを提供できる。
　また、上記（１）の構成のバスバモジュールでは、第２片部の第１片部に対する第２の向きへの回動が規制されている状態においては、係止片の少なくとも一部が係合孔に進入して収容されているので、当該係止片が電線の配索の妨げとなり難い。この結果、電線の配索の容易性が向上されている。
　上記（２）の構成のバスバモジュールでは、撓み変形し易い係止片の長手方向先端側に係止突起が突出しているので、例えば長手方向中間部において左右方向に突出している場合と比較して、容易に係止片を係合孔に進入させることができる。このため、上記（２）の構成のバスバモジュールによれば、電線の配索の容易性を更に向上したバスバモジュールを提供できる。
　上記（３）のバスバモジュールでは、係止片を型抜きするための係止片抜き孔を係合孔として利用しているので、係止片を型抜きするための孔を係合孔以外に別途設ける必要がなく、製造コストを低減できる。
　上記（４）の構成の電源装置によれば、上述した理由と同様の理由により、配索経路の規制における確実性を向上した電源装置を提供できる。 By the way, when routing the electric wire to the electric wire arrangement body, the electric wire arranged in the electric wire arrangement groove portion is obliquely or vertically pulled out from the bottom wall and fixed, and the electric wire is connected to the electric wire outlet portion. It is pulled out along the second piece in a state rotated to a predetermined angle in the first direction with respect to the first piece, and a tie wrap or the like is fixed to the second piece in a state inclined at the predetermined angle. It may be fixed by a member. When fixed in this way, there is a possibility that a force for rotating the second piece portion in a second direction opposite to the first direction may act on the second piece portion due to the tension of the electric wire or the like. For this reason, when the electric wire is fixed to the second piece part with the second piece part being rotatable with respect to the first piece part, the second piece part is second from the predetermined angle. There was a possibility that the wire could not be pulled out at a desired angle, and the routing route could not be regulated reliably.
On the other hand, in the electric wire arrangement in the bus bar module having the configuration (1), the second piece rotates in the first direction with respect to the first piece, so that the locking piece is engaged. The locking projection that has entered the hole and protruded to the side of the locking piece is hooked on the edge of the engaging hole, so that a second direction opposite to the first direction of the second piece is obtained. Rotation in the direction is restricted. For this reason, in the electric wire arrangement | positioning body in the bus bar module of the structure of said (1), a 2nd piece part is hard to rotate in a 2nd direction. Therefore, when the electric wire is pulled out along the electric wire outlet and fixed to the second piece, the second piece is prevented from rotating in the second direction due to the tension of the electric wire, etc. Can be pulled out at a desired angle. For this reason, according to the bus bar module of the structure of said (1), the bus bar module which improved the certainty in regulation of a routing route can be provided.
Further, in the bus bar module configured as described in (1) above, at least a part of the locking piece is engaged when the rotation of the second piece in the second direction with respect to the first piece is restricted. Since it enters and is accommodated in the hole, the locking piece is unlikely to hinder the wiring of the electric wire. As a result, the ease of wiring of the electric wire is improved.
In the bus bar module configured as described above (2), since the locking projection protrudes on the distal end side in the longitudinal direction of the locking piece that is easily bent and deformed, for example, compared with a case where it protrudes in the left-right direction at the longitudinal intermediate portion. Thus, the locking piece can easily enter the engagement hole. For this reason, according to the bus bar module of the structure of said (2), the bus bar module which further improved the ease of wiring of an electric wire can be provided.
In the bus bar module of the above (3), since the locking piece punching hole for punching the locking piece is used as the engaging hole, the hole for punching the locking piece other than the engaging hole is used. There is no need to provide it separately, and the manufacturing cost can be reduced.
According to the power supply device having the configuration (4), it is possible to provide a power supply device with improved reliability in the regulation of the routing route for the same reason as described above.
　本発明によれば、電線を配索し易いバスバモジュール及び電源装置を提供できる。 According to the present invention, it is possible to provide a bus bar module and a power supply device that are easy to route electric wires.

　図７（ａ）、図７（ｂ）及び図８に示すように、比較例に係るバスバモジュールの電線導出部８１Ｂでは、係止片９１、係止片抜き孔８６等を備えていないために、図７（ｂ）に示す状態において、第２片部８７の第１片部８３に対する第２の向きＣ２への回動は規制されていない。 As shown in FIG. 7A, FIG. 7B, and FIG. 8, the wire lead-out portion 81B of the bus bar module according to the comparative example does not include the locking piece 91, the locking piece extraction hole 86, and the like. In the state shown in FIG. 7B, the rotation of the second piece 87 in the second direction C2 relative to the first piece 83 is not restricted.
　上述した実施形態の場合と同様に、電線配索溝部６４に配索された電線束５Ｃを底壁６５から垂直に引き出し、第１片部８３に対して第１の向きＣ１に略垂直に回動させた状態（図７（ｂ）に示す状態）の第２片部８７に固定部材８２で固定した場合には、電線束５Ｃの張力等によって、当該第２片部８７に、第１の向きＣ１とは逆向きの第２の向きＣ２に回動させようとする力が作用する虞がある。 As in the case of the above-described embodiment, the wire bundle 5C routed in the wire routing groove portion 64 is pulled out vertically from the bottom wall 65 and rotated substantially vertically in the first direction C1 with respect to the first piece portion 83. When the second member 87 is fixed to the second piece 87 in the moved state (the state shown in FIG. 7B) by the fixing member 82, the first piece 87 is moved to the first piece 87 by the tension of the wire bundle 5C. There is a possibility that a force to rotate in the second direction C2 opposite to the direction C1 acts.
　このような場合に、比較例に係るバスバモジュールでは、第２片部８７の第１片部８３に対する第２の向きＣ２への回動は規制されていないため、第２片部８７及び該第２片部８７に固定された電線束５Ｃが図８に示すように第２の向きＣ２へ回動してしまい、電線束５Ｃを所望の角度で引き出すことができず、配索経路を確実に規制できない虞があった。 In such a case, in the bus bar module according to the comparative example, the rotation of the second piece 87 in the second direction C2 with respect to the first piece 83 is not restricted. The wire bundle 5C fixed to the two-piece portion 87 rotates in the second direction C2 as shown in FIG. 8, and the wire bundle 5C cannot be pulled out at a desired angle, so that the routing route is surely provided. There was a possibility that it could not be regulated.
　これに対して、実施形態に係るバスバモジュール１の電線配索体６では、第２片部８７が第１片部８３に対して第１の向きＣ１に回動することにより、係止片９１が係止片抜き孔８６に進入して、係止片９１の先端側に突出した係止突起９３が係止片抜き孔８６の縁部に引っ掛かっており、これにより、第２片部８７の第１の向きＣ１とは逆向きの第２の向きＣ２への回動が規制されている。このため、実施形態に係るバスバモジュール１では、第２片部８７が第２の向きＣ２に回動し難い。したがって、電線束５Ｃを電線導出部８１に沿って引き出して第２片部８７に固定した場合に、電線束５Ｃの張力等により第２片部８７が第２の向きＣ２に回動してしまうことが防止されるので、電線束５Ｃを所望の角度で引き出すことができ易い。このため、実施形態に係るバスバモジュール１によれば、配索経路の規制における確実性を向上したバスバモジュールを提供できる。また、実施形態に係る電源装置１０によれば、上述した理由と同様の理由により、配索経路の規制における確実性を向上した電源装置を提供できる。 On the other hand, in the electric wire routing body 6 of the bus bar module 1 according to the embodiment, the second piece 87 rotates in the first direction C1 with respect to the first piece 83, whereby the locking piece 91 is obtained. Enters the locking piece punching hole 86, and the locking projection 93 protruding to the distal end side of the locking piece 91 is hooked on the edge of the locking piece punching hole 86. The rotation in the second direction C2 opposite to the first direction C1 is restricted. For this reason, in the bus bar module 1 according to the embodiment, the second piece 87 is difficult to rotate in the second direction C2. Therefore, when the wire bundle 5C is pulled out along the wire lead-out portion 81 and fixed to the second piece portion 87, the second piece portion 87 rotates in the second direction C2 due to the tension of the wire bundle 5C or the like. This prevents the wire bundle 5C from being pulled out at a desired angle. For this reason, according to the bus bar module 1 which concerns on embodiment, the bus bar module which improved the reliability in the regulation of a routing route can be provided. Moreover, according to the power supply device 10 which concerns on embodiment, the power supply device which improved the certainty in regulation of a wiring path | route can be provided for the reason similar to the reason mentioned above.
　また、実施形態に係るバスバモジュール１の電線配索体６では、第２片部８７の第１片部８３に対する第２の向きＣ２への回動が規制されている状態においては、係止片９１の少なくとも一部が係止片抜き孔８６に進入して収容されているので、当該係止片９１が電線束５Ｃの配索の妨げとなり難い。この結果、電線５の配索の容易性が向上されている。 Moreover, in the electric wire arrangement | positioning body 6 of the bus bar module 1 which concerns on embodiment, in the state in which rotation to the 2nd direction C2 with respect to the 1st piece part 83 of the 2nd piece part 87 is controlled, a locking piece Since at least a part of 91 enters and is received in the locking piece punching hole 86, the locking piece 91 is unlikely to hinder the wiring of the wire bundle 5C. As a result, the ease of wiring of the electric wire 5 is improved.
　また、上記実施形態に係るバスバモジュール１の電線配索体６では、撓み変形し易い係止片９１の長手方向先端側に係止突起９３が突出しているので、例えば長手方向中間部において左右方向に突出している場合と比較して、容易に係止片９１を係止片抜き孔８６に進入させることができる。このため、上記実施形態に係るバスバモジュール１によれば、電線５の配索の容易性を更に向上したバスバモジュールを提供できる。 Moreover, in the electric wire routing body 6 of the bus bar module 1 according to the above-described embodiment, since the locking protrusion 93 protrudes on the distal end side in the longitudinal direction of the locking piece 91 that is easily bent and deformed, for example, in the left-right direction at the longitudinal intermediate portion Compared with the case where it protrudes, the locking piece 91 can be made to enter the locking piece punching hole 86 easily. For this reason, according to the bus bar module 1 which concerns on the said embodiment, the bus bar module which further improved the ease of wiring of the electric wire 5 can be provided.
　以下では、実施形態に係るバスバモジュール１及び電源装置１０について纏める。

（２）また、実施形態に係るバスバモジュール１は、前記係止突起９３が、前記係止片９１の先端側に突出するように形成されている。

(1) The bus bar module 1 according to the embodiment includes a plurality of bus bars 3 that connect the batteries 20 of the battery assembly 2 including the plurality of batteries 20 to each other, and the batteries 20 through the plurality of bus bars 3. And a plurality of electric wires 5 connected to the electric wire arrangement body 6. The wire routing body 6 includes a bowl-shaped wire routing groove portion 64 that accommodates the plurality of wires 5, and a wire lead-out portion 81 provided in the wire routing groove portion 64, and the wire lead-out portion 81. It is an electric wire arrangement | positioning body from which the said electric wire 5 is pulled out along. The wire lead-out portion 81 is provided continuously with a first piece 83 connected to the bottom wall 65 of the wire routing groove 64 and a side 84 of the first piece 83 via a hinge 85 so as to be rotatable. The second piece portion 87 is provided. A locking piece 91 extending in a direction orthogonal to (intersecting with) the second piece portion 87 is projected from the end portion on the one side 84 side of the second piece portion 87. Further, the locking piece 91 is provided with a locking projection 93 protruding from the distal end side (side) of the locking piece 91. The first piece 83 is formed with a locking piece extraction hole 86 (engagement hole) so as to be adjacent to the locking piece 91 with the one side 84 in between. Then, when the second piece 87 rotates in the first direction C1 with respect to the first piece 83, the locking piece 91 enters the locking piece extraction hole 86, and the engagement A stop projection 93 is hooked on the edge of the locking piece punching hole 86, whereby the second piece 87 has a second direction opposite to the first direction C1 with respect to the first piece 83.

　尚、本発明の技術的範囲は、上述した実施形態に限定されるものではない。上述した実施形態は、本発明の技術的範囲内で種々の変形や改良等を伴うことができる。 Note that the technical scope of the present invention is not limited to the above-described embodiment. The above-described embodiments can be accompanied by various modifications and improvements within the technical scope of the present invention.
　例えば、上記実施形態においては、図４に示したように、電線配索溝部６４に収容されて配索された電線５を、第１片部８３に対して略直交した状態の第２片部８７に沿って、図４中の紙面手前方向に引き出す構成について説明したが、電線の引き出し方向はこれに限られない。例えば、電線５を、第１片部８３に対して所定の角度（例えば、６０度）だけ傾斜した状態の第２片部８７に沿って引き出す構成としても構わない。例えば、この場合には、係止片９１を、第２片部８７から当該所定の角度に対応した角度だけ傾斜するように、即ち第２片部８７と交差するように突設する構成とすればよい。これにより、第２片部８７を第１片部８３に対して当該所定の角度まで回動させた際に、係止片９１が係止片抜き孔８６に進入して係止突起９３が係止片抜き孔８６の縁部に引っ掛かり、第２片部９７が第１片部８３に対して所定の角度だけ傾斜した状態で回動規制状態となる。この結果、回動が規制された第２片部８７に沿って電線５を所定の角度で引き出すことができる。 For example, in the said embodiment, as shown in FIG. 4, the 2nd piece part of the state in which the electric wire 5 accommodated and wired by the electric wire routing groove part 64 was substantially orthogonally crossed with respect to the 1st piece part 83. Although the configuration of drawing out in the front direction of the paper in FIG. 4 along the line 87 has been described, the drawing direction of the electric wire is not limited to this. For example, the electric wire 5 may be configured to be pulled out along the second piece 87 that is inclined by a predetermined angle (for example, 60 degrees) with respect to the first piece 83. For example, in this case, the locking piece 91 is configured to project from the second piece portion 87 so as to be inclined by an angle corresponding to the predetermined angle, that is, to intersect the second piece portion 87. That's fine. Thus, when the second piece 87 is rotated with respect to the first piece 83 to the predetermined angle, the locking piece 91 enters the locking piece punching hole 86 and the locking projection 93 is engaged. The second piece 97 is caught by the edge of the stop hole 86 and the rotation is restricted in a state where the second piece 97 is inclined with respect to the first piece 83 by a predetermined angle. As a result, the electric wire 5 can be pulled out at a predetermined angle along the second piece portion 87 whose rotation is restricted.
　また、上記実施形態においては、第２片部８７が、第１片部８３に対して略直交した状態となる図５（ｂ）に示す位置までしか回動しないように、ヒンジ８５が形成されている構成としたが、当該位置を超えて回動可能に構成されていても構わない。即ち、図５（ｂ）及び図６に示す状態において、電線導出部８１が、第２片部８７の第２の向きＣ２への回動のみが規制された状態となる構成であっても構わない。このような構成であっても、電線５の張力等により第２片部８７が第２の向きＣ２に回動してしまうことを防止できる。但し、上記実施形態のように、第２片部８７の第１の向きＣ１及び第２の向きＣ２の双方向への回動が規制される構成であれば、例えば第２片部８７を第１の向きＣ１に回動させる外力が電線５に作用した場合であっても、電線５の配索経路を確実に規制できるという効果が得られる。 Further, in the above embodiment, the hinge 85 is formed so that the second piece 87 is rotated only to the position shown in FIG. 5B where the second piece 87 is substantially orthogonal to the first piece 83. However, it may be configured to be rotatable beyond the position. That is, in the state shown in FIG. 5B and FIG. 6, the wire lead-out portion 81 may be configured such that only the rotation of the second piece portion 87 in the second direction C2 is restricted. Absent. Even in such a configuration, it is possible to prevent the second piece 87 from rotating in the second direction C2 due to the tension of the electric wire 5 or the like. However, as in the above-described embodiment, if the second piece 87 is configured to restrict the bi-directional rotation of the first direction C1 and the second direction C2, for example, the second piece 87 may be Even when an external force that rotates in the direction C <b> 1 acts on the electric wire 5, an effect that the routing route of the electric wire 5 can be reliably controlled is obtained.
　また、上記実施形態においては、係止突起９３が、係止片９１の先端側に突出する構成としたが、係止片９１の側方（即ち、先端側及び左右側方を含む方向）に突出する構成であればよい。即ち、第２片部８７が第１の向きＣ１に回動し、係止片９１が係止片抜き孔８６に進入した場合に、係止突起９３が係止片抜き孔８６の縁部に引っ掛かっる構成であればよく、例えば、係止突起９３が係止片９１の左右両側方に突出する構成であっても構わない。このような構成とすれば、係止片９１をより強固に係止片抜き孔８６に係止することができる。 Moreover, in the said embodiment, although the latching protrusion 93 was set as the structure protruded to the front end side of the latching piece 91, it is to the side (namely, direction including a front end side and the left-right side) of the latching piece 91. What is necessary is just the structure which protrudes. That is, when the second piece 87 is rotated in the first direction C1 and the locking piece 91 enters the locking piece punching hole 86, the locking projection 93 is formed at the edge of the locking piece punching hole 86. For example, a configuration in which the locking protrusion 93 protrudes to the left and right sides of the locking piece 91 may be used. With such a configuration, the locking piece 91 can be locked to the locking piece extraction hole 86 more firmly.
　また、上記実施形態においては、電線配索体６を成形する際に係止片９１を型抜きするための係止片抜き孔８６を、係止片９１が係止される係合孔として利用する構成としたが、型抜き用の孔とは別個に係止片９１が係止される係合孔を設ける構成としても構わない。 Moreover, in the said embodiment, when shape | molding the electric wire wiring body 6, the latching piece punching hole 86 for punching out the latching piece 91 is utilized as an engagement hole by which the latching piece 91 is latched. However, a configuration may be adopted in which an engagement hole for locking the locking piece 91 is provided separately from the hole for punching.
　本発明を詳細にまた特定の実施態様を参照して説明したが、本発明の精神と範囲を逸脱することなく様々な変更や修正を加えることができることは当業者にとって明らかである。 Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
