Description

本発明は、配線モジュールに関する。   The present invention relates to a wiring module.

電気自動車やハイブリッド車用の電池モジュールは、正極及び負極の電極端子を有する単電池が複数個並んで配列されており、隣り合う単電池の電極端子間がバスバー(接続部材)で接続されることにより複数の単電池が直列や並列に接続されるようになっている。   In battery modules for electric vehicles and hybrid vehicles, a plurality of single cells having positive and negative electrode terminals are arranged side by side, and electrode terminals of adjacent single cells are connected by a bus bar (connection member). Thus, a plurality of single cells are connected in series or in parallel.

ここで、下記特許文献1のように、合成樹脂製の複数の単位ユニットにそれぞれ接続部材を収容し、隣り合う単位ユニットを連結することにより、複数の接続部材を一体的に装着することが考えられた。   Here, as in Patent Document 1 below, it is considered that a plurality of connecting members are integrally mounted by accommodating connecting members in a plurality of unit units made of synthetic resin, and connecting adjacent unit units. It was.

この特許文献1の電池接続アセンブリは、各単位ユニットの並び方向の一方の端部に、円柱状の延出部が並び方向に突出した係合部が設けられるとともに、並び方向の他方の端部に隣り合う単位ユニットの係合部と係合する被係合部が設けられている。この係合部には、延出部の先端に張出部が設けられており、被係合部には、延出部が嵌め込まれる挿通凹部が設けられている。   In the battery connection assembly of Patent Document 1, an engagement portion in which a columnar extending portion protrudes in the arrangement direction is provided at one end portion in the arrangement direction of the unit units, and the other end portion in the arrangement direction. An engaged portion that engages with an engaging portion of a unit unit adjacent to the unit unit is provided. The engaging portion is provided with a protruding portion at the tip of the extending portion, and the engaged portion is provided with an insertion concave portion into which the extending portion is fitted.

そして、このような複数の単位ユニット(連結部材)が係合部と被係合部とによって互いに連結されて電池接続アセンブリが構成されるようになっている。また、電池接続アセンブリを複数並んで配列された単電池群に装着することで、複数の単電池が直列や並列に接続される。   A plurality of such unit units (connecting members) are connected to each other by the engaging portion and the engaged portion to form a battery connection assembly. Moreover, a plurality of unit cells are connected in series or in parallel by attaching a plurality of cell connection assemblies to the unit cell group arranged side by side.

ここで、この電池接続アセンブリ(配線モジュール)は、係合部の円柱部分と挿通凹部により隣り合う単位ユニット(連結部材)間において並び方向への相対的な変位が許容されており、隣り合う複数の単電池の電極端子間に寸法公差がある場合であっても、単位ユニット(連結部材)間が相対的に移動することで、電極端子間の寸法公差に対応できるようになっている。   Here, in the battery connection assembly (wiring module), relative displacement in the alignment direction is allowed between the adjacent unit units (connecting members) by the cylindrical portion of the engaging portion and the insertion recess, and a plurality of adjacent battery units are connected. Even when there is a dimensional tolerance between the electrode terminals of the single cell, the dimensional tolerance between the electrode terminals can be accommodated by the relative movement between the unit units (connecting members).

特開2011−175928号公報JP 2011-175828 A

ところで、配線モジュールを単電池に装着する際には、複数の単電池間の寸法公差のために、一般に、全ての連結部材を一体的に単電池群に組み付けることはせず、並び方向の一方の端部の連結部材から他方の端部側の連結部材へと順番に組み付けていく方が効率的である。   By the way, when mounting a wiring module to a unit cell, due to dimensional tolerances between a plurality of unit cells, in general, all connecting members are not integrally assembled into a unit cell group. It is more efficient to assemble in order from the connecting member on the other end to the connecting member on the other end.

ここで、この組み付けの際に、連結部材が並び方向に一直線状に連結されていると、単電池間の寸法公差に対応させることが難しいため、単電池群への組み付け作業性の観点から望ましくない。一方、並んで配列された連結部材を単電池群への組み付け方向とは反対側に撓ませることができれば、並び方向の一方の端部側の連結部材から並び方向の他方の端部側の連結部材へと順番に組み付けていくことが可能となり、配線モジュールの組み付け作業性を向上させることができる。   Here, if the connecting members are connected in a straight line in the arrangement direction at the time of this assembly, it is difficult to correspond to the dimensional tolerance between the single cells, which is desirable from the viewpoint of the workability of the assembly to the single cell group. Absent. On the other hand, if the connecting members arranged side by side can be bent in the direction opposite to the assembly direction to the unit cell group, the connecting member on one end side in the arranging direction can be connected on the other end side in the arranging direction. It becomes possible to assemble to a member in order, and the assembling workability of the wiring module can be improved.

しかしながら、特許文献1の構成では、隣り合う連結部材について、延出部の外周を挿通凹部に(ほとんど隙間なく)嵌め込んで連結する構成であるため、配線モジュール(複数並んで配列された連結部材)を単電池群への組み付け方向とは反対側に撓ませることが容易ではなく、配線モジュールの組み付け作業性が低下しやすいという問題があった。   However, in the configuration of Patent Document 1, since the adjacent connecting members are connected by fitting the outer periphery of the extended portion into the insertion recess (with almost no gap), a wiring module (a plurality of connecting members arranged side by side) ) Is not easy to bend in the direction opposite to the assembly direction to the unit cell group, and there is a problem that the workability of assembling the wiring module is likely to deteriorate.

本発明は上記のような事情に基づいて完成されたものであって、単電池群への組み付け作業性を向上させることが可能な配線モジュールを提供することを目的とする。   This invention is completed based on the above situations, Comprising: It aims at providing the wiring module which can improve the assembly workability | operativity to a cell group.

本発明に係る配線モジュールは、正極及び負極の電極端子を有する複数の単電池からなる単電池群に組み付けられる配線モジュールであって、前記複数の単電池に電気的に接続される複数の電線が配策される樹脂プロテクタを備え、前記樹脂プロテクタは、複数の連結部材が連結されて構成されるものであり、前記各連結部材は、当該連結部材における並び方向の一端側に設けられて前記並び方向に突出する連結突片と、前記連結部材における並び方向の他端側に設けられて隣り合う前記連結部材の前記連結突片が挿通される連結挿通部とを備えており、前記連結突片は、前記連結挿通部に挿通された状態で、前記単電池群への組み付け方向における前記連結挿通部との間に所定のクリアランスを形成する切欠部を有し、前記所定のクリアランスにより前記樹脂プロテクタにおける前記単電池群への組み付け方向とは反対側への撓み変形が許容される。   The wiring module according to the present invention is a wiring module that is assembled to a unit cell group including a plurality of unit cells having positive and negative electrode terminals, and a plurality of electric wires that are electrically connected to the plurality of unit cells. The resin protector includes a plurality of connecting members, and each of the connecting members is provided on one end side in the arranging direction of the connecting members. A connecting protrusion that protrudes in the direction, and a connecting insertion portion that is provided on the other end side in the alignment direction of the connecting member and through which the connecting protrusion of the adjacent connecting member is inserted.

なお、樹脂プロテクタにおける単電池群への組み付け方向については、切欠部を設けないことで所定のクリアランスを形成しないようにすれば、樹脂プロテクタにおける単電池群への組み付け方向の撓み変形を規制することができる。よって、例えば、単電池群への組み付けの前に樹脂プロテクタを持ち上げた際における組み付け方向の撓み変形を規制できるため、配線モジュールの組み付け位置への移動の際の作業性の低下を抑制できる。
According to this configuration, the predetermined clearance allows the resin protector to bend and deform in the direction opposite to the direction in which the resin protector is assembled to the unit cell group. Assembling in order to the other side becomes easy. Therefore, it is possible to improve the workability of assembling the wiring module to the single cell group.
In addition, as for the assembly direction of the resin protector to the unit cell group, if the predetermined clearance is not formed by not providing the notch portion, the deformation deformation in the assembly direction of the resin protector to the unit cell group is restricted. Can do. Therefore, for example, since bending deformation in the assembling direction when the resin protector is lifted before assembling to the unit cell group can be restricted, it is possible to suppress a decrease in workability when the wiring module is moved to the assembling position.

連結挿通部36は、図10に示すように、各連結突片46,47を挿通可能な大きさで形成されており、連結突片46,47の上側に配される上壁37と、上壁37の奥端から下方に延びる奥壁38と、連結突片46,47の下側に配される係合壁39とを備える。
係合壁39は、金型の抜きを可能とするために、上壁37に対しては左方に位置をずらし、奥壁38に対しては、下方に位置をずらして形成されている。
As shown in FIG. 10, the connecting insertion part 36 is formed in a size that allows the connecting protruding pieces 46 and 47 to be inserted, and includes an upper wall 37 disposed on the upper side of the connecting protruding pieces 46 and 47, A back wall 38 extending downward from the back end of the wall 37 and an engagement wall 39 disposed below the connecting protrusions 46 and 47 are provided.
The engagement wall 39 is formed so that the position is shifted to the left with respect to the upper wall 37 and the position is shifted downward with respect to the back wall 38 in order to allow the mold to be removed.

この係合壁39の上端は、樹脂プロテクタ25を撓み変形させる際に、連結突片46,47の下端の後述する切欠部49に係合して、樹脂プロテクタ25の過度の撓み変形を規制する。
また、連結挿通部36は、図5に示すように、互いに向かい合う方向に突出する一対の被係止部40A,40Bを有する。
被係止部40A,40Bは、上壁37及び奥壁43に連なるように設けられており、連結突片46,47側に鉤状に突出している。
When the resin protector 25 is bent and deformed, the upper end of the engagement wall 39 engages with a notch 49 (described later) at the lower ends of the connecting protrusions 46 and 47 to restrict excessive deformation of the resin protector 25. .
Moreover, the connection insertion part 36 has a pair of to-be-latched part 40A, 40B which protrudes in the direction which mutually faces, as shown in FIG.
The locked portions 40A and 40B are provided so as to be continuous with the upper wall 37 and the back wall 43, and protrude in a hook shape toward the connecting protrusions 46 and 47 side.

ガイド受け部41は、図6に示すように、ガイド突片48を挿通可能な大きさで形成されており、ガイド突片48の上方に配される上壁42と、上壁42の奥端から下方に延びる奥壁43と、ガイド突片48の下方に配される係合壁44と、を備える。
係合壁44は、金型の抜きを可能とするために、上壁42に対しては左方に位置をずらし、奥壁43に対しては、下方に位置をずらして形成されている。
この係合壁44は、樹脂プロテクタ25を撓み変形させる際に、ガイド突片48の下端の切欠部49に当接して、樹脂プロテクタ25の過度の撓み変形を規制する。
As shown in FIG. 6, the guide receiving portion 41 is formed in such a size that the guide protruding piece 48 can be inserted, and an upper wall 42 disposed above the guide protruding piece 48 and a rear end of the upper wall 42. And an engagement wall 44 disposed below the guide protrusion 48.
The engagement wall 44 is formed with a position shifted to the left with respect to the upper wall 42 and a position shifted downward with respect to the back wall 43 in order to enable removal of the mold.
When the resin protector 25 is bent and deformed, the engaging wall 44 abuts against a notch 49 at the lower end of the guide protrusion 48 to restrict excessive deformation of the resin protector 25.

一対の連結突片46,47及びガイド突片48は、共に上下方向(配線モジュール20の組み付け方向)に厚肉であって、前後方向(組み付け方向と直交する方向)に薄肉に形成されている。連結突片46,47は、前後方向に薄肉の形状ゆえに、前後方向に撓み変形可能になっている。一対の連結突片46,47は、その各基端部間にわずかな隙間を有しており、先端側に向けて互いに離間する(広がる)方向に傾斜している。   The pair of connecting projecting pieces 46 and 47 and the guide projecting piece 48 are both thick in the vertical direction (the assembly direction of the wiring module 20) and thin in the front-rear direction (the direction perpendicular to the assembly direction). . Since the connecting protrusions 46 and 47 are thin in the front-rear direction, they can be bent and deformed in the front-rear direction. The pair of connecting protrusions 46 and 47 have a slight gap between their base ends, and are inclined in a direction of separating (expanding) from each other toward the distal end side.

連結突片46,47及びガイド突片48の下側には、この下端を傾斜状に切欠いた切欠部49が形成されている。
切欠部49は、連結突片46,47及びガイド突片48の上下方向の寸法を先端側に向かう程短くするように下端側を切欠いて形成されている。より詳しくは、切欠部49は、連結突片46,47及びガイド突片48が、連結部材26が正常に連結される位置である正規連結位置まで(左右方向に)連結挿通部36に挿通された際に、連結突片46,47の切欠部49と係合壁39,44の上端との間に所定のクリアランスCLを形成する大きさで切欠かれている。
On the lower side of the connecting projecting pieces 46 and 47 and the guide projecting piece 48, a notch 49 is formed by notching the lower end in an inclined manner.
The notch 49 is formed by notching the lower end side so that the vertical dimensions of the connecting protrusions 46 and 47 and the guide protrusion 48 are shortened toward the distal end side. More specifically, the cutout portion 49 is inserted through the connection insertion portion 36 to the normal connection position (in the left-right direction) where the connection protrusions 46 and 47 and the guide protrusion 48 are positions where the connection member 26 is normally connected. In this case, the connection protrusions 46 and 47 are notched in such a size that a predetermined clearance CL is formed between the notches 49 and 47 and the upper ends of the engagement walls 39 and 44.

所定のクリアランスCLは、配線モジュール20の組み付けの際に、配線モジュール20(樹脂プロテクタ25)を組み付け方向とは反対側に撓ませて、連結ユニット20Aを複数の単電池11に1個ずつ順番に組み付けやすい寸法に設定されるものであり、例えば、電極端子12A,12Bの高さ等に応じて撓ませる必要がある大きさに設定される。
一方、一対の連結突片46,47及びガイド突片48は、上方側については、切欠部49が設けられておらず、上端50がほぼ水平方向に延出されているため、樹脂プロテクタ25の組み付け方向に撓もうとする力に対しては、同様に水平方向に延出された上壁37の下面に当接することで、樹脂プロテクタ25の組み付け方向については撓み変形が抑制される。
The predetermined clearance CL is obtained by bending the wiring module 20 (resin protector 25) in the direction opposite to the assembling direction when the wiring module 20 is assembled, and sequentially connecting the connecting units 20A to the plurality of single cells 11 one by one. The dimension is set to a size that is easy to assemble, and is set to a size that needs to be bent according to the height of the electrode terminals 12A and 12B, for example.
On the other hand, the pair of connecting projecting pieces 46 and 47 and the guide projecting piece 48 are not provided with the notch 49 on the upper side, and the upper end 50 extends substantially in the horizontal direction. For the force to bend in the assembling direction, the deformation of the resin protector 25 in the assembling direction is suppressed by contacting the lower surface of the upper wall 37 extending in the horizontal direction.

また、一対の連結突片46,47の各先端部には、互いに背き合う方向に突出する係止部51,52が設けられている。係止部51,52は、図5に示すように、連結挿通部36に設けられた被係止部40A,40Bに係止可能な形状であって、互いに背き合う方向に段差状に突出する段差部53と、段差部53の先方にて傾斜状に突出寸法が小さくなる傾斜部54とを有する。なお、ガイド突片48及びガイド受け部41には、係止部51,52及び被係止部40A,40Bに対応する左右方向(並び方向)の移動を規制する構成は設けられていない。   In addition, locking portions 51 and 52 are provided at the distal ends of the pair of connecting protrusions 46 and 47 so as to protrude in directions opposite to each other. As shown in FIG. 5, the locking portions 51 and 52 have a shape that can be locked to the locked portions 40 </ b> A and 40 </ b> B provided in the connection insertion portion 36, and project in a stepped manner in a direction that is mutually opposite. There is a stepped portion 53 and an inclined portion 54 having a protruding dimension that is inclined in an inclined manner at the tip of the stepped portion 53. The guide projecting piece 48 and the guide receiving portion 41 are not provided with a configuration for restricting the movement in the left-right direction (alignment direction) corresponding to the locking portions 51 and 52 and the locked portions 40A and 40B.

樹脂プロテクタ25を上方(組み付け方向とは反対側)に撓ませようとする力が生じた際に、隣り合う連結部材26間が相対的に離間する方向に移動すると、上方への撓み変形が大きくなりすぎたり、隣り合う連結部材26間の連結が解除される不具合が懸念される。また、樹脂プロテクタ25を下方(組み付け方向)に撓ませようとする力が生じた際に、隣り合う連結部材26間が相対的に離間する方向に移動すると、組み付けの際に撓ませたくない下方についても樹脂プロテクタ25が撓んでしまうことが懸念される。   When a force that causes the resin protector 25 to bend upward (opposite to the assembly direction) is generated, if the adjacent connecting members 26 are moved away from each other, the upward bending deformation is large. There is a concern that the connection between the connecting members 26 adjacent to each other may be excessively released. Further, when a force is generated to bend the resin protector 25 downward (in the assembling direction) and the adjacent connecting members 26 move in a direction in which they are relatively separated from each other, it is not desired to bend in the assembling. There is a concern that the resin protector 25 may be bent.

一方、本実施形態では、連結突片46,47が連結挿通部36に挿通されると、連結突片46,47が被係止部40A,40Bに当接して撓み、連結突片46,47が正規連結位置まで挿通されて連結部材26が連結された状態では、連結突片46,47が復元変形して係止部51,52が被係止部40A,40Bの挿入方向の前方に配される。これにより、樹脂プロテクタ25を組み付け方向とは反対側に撓ませようとする力に対しては、被係止部40A,40Bが係止部51,52に係止されることにより、過度の撓みや隣り合う連結部材26間の連結の解除を防止することができる。また、樹脂プロテクタ25を組み付け方向に撓ませようとする力に対しては、連結部材26間の相対的な移動が規制されることで樹脂プロテクタ25の撓み変形を抑制することができる。   On the other hand, in this embodiment, when the connecting protrusions 46 and 47 are inserted into the connecting insertion part 36, the connecting protrusions 46 and 47 come into contact with the locked parts 40A and 40B and bend, thereby connecting protrusions 46 and 47. Is inserted to the normal connection position and the connecting member 26 is connected, the connecting projecting pieces 46 and 47 are restored and deformed, and the locking portions 51 and 52 are arranged in the insertion direction of the locked portions 40A and 40B. Is done. Thereby, with respect to the force to bend the resin protector 25 in the direction opposite to the assembly direction, the locked portions 40A and 40B are locked by the locking portions 51 and 52, thereby excessive bending. Further, it is possible to prevent the connection between the adjacent connecting members 26 from being released. Moreover, with respect to the force which is going to bend the resin protector 25 to an assembly direction, the deformation | transformation deformation of the resin protector 25 can be suppressed because the relative movement between the connection members 26 is controlled.

The locking hole 62 is a through hole that penetrates the cover main body 56, and has a rectangular shape that is long in the front-rear direction according to the shape of the cover locking portion 59.
Then, when the cover engaging portion 57 is inserted into the cover insertion portion 61 to the normal connection position, the cover locking portion 59 is disposed in the locking hole 62 and the adjacent cover portions 55 are connected. At this time, with respect to the force in the direction in which the adjacent cover portions 55 are separated from each other, the cover locking portion 59 is locked to the hole edge of the locking hole 62 so that the connected state of the cover portion 55 is maintained. .

次に、配線モジュール20の組み付けについて説明する。
まず、接続部材21を保持部27のうち仕切り壁28が設けられていない側方側から左右方向に挿入し、接続部材21を保持部27内に保持する。
次に、カバー係合部57をカバー被係合部60に係合させるとともに、連結部材26のガイド突片48及び連結突片46,47を隣の連結部材26のガイド受け部41及び連結挿通部36に挿通する。
Next, assembly of the wiring module 20 will be described.
First, the connecting member 21 is inserted in the horizontal direction from the side of the holding portion 27 where the partition wall 28 is not provided, and the connecting member 21 is held in the holding portion 27.
Next, the cover engaging portion 57 is engaged with the cover engaged portion 60, and the guide protrusion 48 and the connecting protrusions 46, 47 of the connecting member 26 are connected to the guide receiving portion 41 of the adjacent connecting member 26 and the connecting insertion. The part 36 is inserted.

この連結の際の順番は、まず、カバー係合部57の板状突片58をカバー被係合部60のカバー挿通部61に挿通し、その後、ガイド突片48をガイド受け部41に挿通し、次に、連結突片46,47を連結挿通部36に挿通する。   In this connection, first, the plate-like protrusion 58 of the cover engaging portion 57 is inserted into the cover insertion portion 61 of the cover engaged portion 60, and then the guide protrusion 48 is inserted into the guide receiving portion 41. Then, the connecting protrusions 46 and 47 are inserted into the connecting insertion part 36.

そして、板状突片58がカバー挿通部61に、ガイド突片48をガイド受け部41、連結突片46,47が連結挿通部36に、共に正規連結位置まで挿通されると、隣り合う連結部材26が正規に連結された状態となる。同様に連結すべき全ての連結部材26について連結することで複数の接続部材21が収容された状態の樹脂プロテクタ25が形成される。   When the plate-like protrusion 58 is inserted into the cover insertion portion 61, the guide protrusion 48 is inserted into the guide receiving portion 41, and the connection protrusions 46 and 47 are inserted into the connection insertion portion 36 to the normal connection position, the adjacent connection portions are connected. The member 26 is normally connected. Similarly, the resin protector 25 in a state in which the plurality of connecting members 21 are accommodated is formed by connecting all the connecting members 26 to be connected.

次に、電線の端末に接続された電圧検知端子23を接続部材21に重ねて装着し、溝蓋34を開けて電線を電線収容溝に通し、電線を配策したら溝蓋34を閉じる。
これにより、複数の連結ユニット20Aが連結された配線モジュール20が形成される(図2)。
Next, the voltage detection terminal 23 connected to the terminal of the electric wire is attached to the connecting member 21 so as to be overlapped, the groove lid 34 is opened, the electric wire is passed through the electric wire receiving groove, and when the electric wire is arranged, the groove lid 34 is closed.
Thereby, the wiring module 20 in which a plurality of connecting units 20A are connected is formed (FIG. 2).

そして、配線モジュール20を、持ち上げ、単電池群13の上方に移動させる。この移動の際には、連結突片46,47が被係止部40A,40Bにより左右方向に係止された状態で連結挿通部36の上壁37と連結突片46,47の上端50、及び、ガイド受け部41の上壁42及びガイド突片48の上端50とが当接することにより下方への撓み変形が抑制されているため、配線モジュール20は、ほぼ水平な状態で持ち上げられる。   Then, the wiring module 20 is lifted and moved above the unit cell group 13. At the time of this movement, the upper wall 37 of the connection insertion part 36 and the upper ends 50 of the connection protrusions 46, 47 in a state where the connection protrusions 46, 47 are locked in the left-right direction by the locked portions 40A, 40B. And since the upper wall 42 of the guide receiving part 41 and the upper end 50 of the guide protrusion 48 contact | abut, the downward bending deformation is suppressed, the wiring module 20 is lifted in a substantially horizontal state.

次に、単電池群13の上方では、図11に示すように、配線モジュール20(の樹脂プロテクタ25)のうち、一方の端部側(の連結部材26)を水平な状態とし、他方の端部側を上方に撓み変形させる。このとき、連結突片46,47及びガイド突片48の下端の切欠部49と、係合壁39,44との間には、所定のクリアランスCLが設けられているため、このクリアランスCLにより配線モジュール20(の樹脂プロテクタ25)を容易に撓ませることができる(図12)。   Next, above the unit cell group 13, as shown in FIG. 11, one end side (the connecting member 26) of the wiring module 20 (resin protector 25) is in a horizontal state, and the other end The part side is bent upward and deformed. At this time, since a predetermined clearance CL is provided between the notch 49 at the lower end of the connecting protrusions 46 and 47 and the guide protrusion 48 and the engaging walls 39 and 44, wiring is performed by this clearance CL. The module 20 (resin protector 25) can be easily bent (FIG. 12).

そして、配線モジュール20の一端側の連結部材26から順番に他端側の連結部材26まで各単電池11の電極端子12A,12Bを接続部材21及び電圧検知端子23の通し孔22,24に通して組み付け、電極端子12A,12Bをナットで締結する。その後、カバー部55を閉じる。これにより、単電池群13に配線モジュール20が組み付けられた電池モジュール10が形成される(図1)。   Then, the electrode terminals 12A and 12B of each unit cell 11 are passed through the connecting members 21 and the through holes 22 and 24 of the voltage detection terminal 23 from the connecting member 26 on one end side of the wiring module 20 to the connecting member 26 on the other end side in order. Then, the electrode terminals 12A and 12B are fastened with nuts. Then, the cover part 55 is closed. Thereby, the battery module 10 by which the wiring module 20 was assembled | attached to the cell group 13 is formed (FIG. 1).

上記実施形態の構成によれば、以下の作用・効果を奏する。
(1)正極及び負極の電極端子12A,12Bを有する複数の単電池11からなる単電池群13に組み付けられる配線モジュール20であって、複数の単電池11に電気的に接続される複数の電線が配策される樹脂プロテクタ25を備え、樹脂プロテクタ25は、複数の連結部材26が連結されて構成されるものであり、各連結部材26は、当該連結部材26における並び方向の一端側に設けられて並び方向に突出する連結突片46,47と、連結部材26における並び方向の他端側に設けられて隣り合う連結部材26の連結突片46,47が挿通される連結挿通部36とを備えており、連結突片46,47は、連結挿通部36に挿通された状態で、単電池群13への組み付け方向における連結挿通部36との間にクリアランスCLを形成する切欠部49を有し、所定のクリアランスCLにより樹脂プロテクタ25における単電池群13への組み付け方向とは反対側への撓み変形が許容される。
According to the structure of the said embodiment, there exist the following effects.
(1) A wiring module 20 assembled to a unit cell group 13 including a plurality of unit cells 11 having positive and negative electrode terminals 12A and 12B, and a plurality of electric wires electrically connected to the plurality of unit cells 11. The resin protector 25 is configured by connecting a plurality of connecting members 26, and each connecting member 26 is provided at one end side of the connecting member 26 in the arrangement direction. Connecting protrusions 46 and 47 that protrude in the alignment direction, and connection insertion portions 36 that are provided on the other end side of the connection member 26 in the alignment direction and through which the connection protrusions 46 and 47 of the adjacent connection members 26 are inserted. The connection protrusions 46 and 47 form a clearance CL between the connection protrusions 46 and 47 and the connection insertion part 36 in the assembly direction to the unit cell group 13 while being inserted into the connection insertion part 36. Has a notch 49, bending deformation of the opposite side is allowed to the direction of assembly of the single cell group 13 in the resin protector 25 by a predetermined clearance CL.

本実施形態によれば、所定のクリアランスCLにより樹脂プロテクタ25における単電池群13への組み付け方向とは反対側への撓み変形が許容されるため、単電池群13に対して連結部材26の並び方向の一方の側から他方の側へと順番に組み付けていく作業が容易になる。よって、配線モジュール20の単電池群13への組み付け作業性を向上させることが可能となる。
なお、樹脂プロテクタ25における単電池群13への組み付け方向については、切欠部49を設けないことで所定のクリアランスCLを形成しないようにすれば、樹脂プロテクタ25における単電池群13への組み付け方向の撓み変形を規制することができる。よって、例えば、単電池群13への組み付けの前に樹脂プロテクタ25を持ち上げた際における組み付け方向の撓み変形を規制できるため、配線モジュール20の組み付け位置への移動の際の作業性の低下を抑制できる。
According to the present embodiment, the predetermined clearance CL allows the resin protector 25 to bend and deform in the direction opposite to the direction in which the resin protector 25 is assembled to the unit cell group 13, so that the connecting members 26 are arranged with respect to the unit cell group 13. The work of assembling in order from one side of the direction to the other side is facilitated. Therefore, the workability of assembling the wiring module 20 to the single cell group 13 can be improved.
In addition, about the assembly direction to the cell group 13 in the resin protector 25, if it does not form the predetermined clearance CL by not providing the notch part 49, the assembly direction to the cell group 13 in the resin protector 25 is the same. Flexural deformation can be regulated. Therefore, for example, since bending deformation in the assembling direction when the resin protector 25 is lifted before assembling to the cell group 13 can be restricted, a decrease in workability when the wiring module 20 is moved to the assembling position is suppressed. it can.

(2)連結突片46,47は、単電池群13への組み付け方向について厚肉の形状である。
このようにすれば、組み付け方向や組み付け方向とは反対方向への力に対する連結突片46,47の剛性を高めることができる。
(2) The connecting protrusions 46 and 47 have a thick shape in the assembling direction to the unit cell group 13.
In this way, it is possible to increase the rigidity of the connecting projections 46 and 47 with respect to the assembly direction and the force in the direction opposite to the assembly direction.

(3)連結突片46,47は、単電池群13への組み付け方向とは直交する方向である肉薄とされた方向に撓み変形可能であり、連結突片46,47の先端部には、連結挿通部36の被係止部40A,40Bに係止する係止部51,52が肉薄とされた方向に突出している。
このようにすれば、連結部材26を連結状態に保持することができる。
(3) The connecting protrusions 46 and 47 can be bent and deformed in a thinned direction which is a direction perpendicular to the assembly direction to the unit cell group 13. The locking portions 51 and 52 that are locked to the locked portions 40A and 40B of the connecting insertion portion 36 protrude in the direction in which the thickness is reduced.
In this way, the connecting member 26 can be held in a connected state.
