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蓄電モジュールは、正極及び負極の電極端子を有する蓄電素子が複数個並んで配列されており、蓄電素子の電極端子間が接続部材で接続されることにより複数の蓄電素子が直列や並列に接続されるようになっている。   A power storage module for an electric vehicle or a hybrid vehicle has a plurality of power storage elements each having a positive electrode electrode and a negative electrode terminal, and a plurality of power storage elements connected by connecting members between the electrode terminals of the power storage elements.

特開２０１２−６４４５７号公報JP 2012-64457 A

ところで、特許文献１の構成では、仮係止カバー部の係止爪が絶縁カバー部に形成された被係止部に係止される構成となっているが、絶縁カバー部に被係止部を設けると、絶縁カバー部に被係止部を形成するために金型の抜き孔を設ける等の加工が必要になり、絶縁性の低下が懸念される。また、絶縁カバー部に電線のガイド部や仮係止構造が設けられるために構成が複雑になるという問題がある。   By the way, in the structure of patent document 1, although it becomes the structure by which the latching claw of a temporary latching cover part is latched by the to-be-latched part formed in the insulating cover part, If it is provided, a process such as providing a die hole in order to form the locked portion in the insulating cover portion is required, and there is a concern that the insulating property may be lowered. In addition, there is a problem that the configuration is complicated because the guide portion and the temporary locking structure of the electric wire are provided in the insulating cover portion.

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、簡素な構成で絶縁性の低下を抑制す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 suppress a fall of insulation with a simple structure.

本発明の配線モジュールは、正極及び負極の電極端子を有する複数の蓄電素子における隣り合う前記電極端子間を接続する接続部材と、前記接続部材を保持する本体と前記接続部材を覆う絶縁カバーとを有する絶縁プロテクタと、前記絶縁プロテクタに配索され、前記接続部材に沿うように配された配索経路が前記接続部材の上の経路を通るように迂回して前記接続部材と前記絶縁カバーとの間に通される電線と、を備え、前記接続部材と前記絶縁カバーとの間に通された前記電線は、絶縁性の保護部材で覆われている。 A wiring module according to the present invention includes a connection member that connects adjacent electrode terminals in a plurality of power storage elements having positive and negative electrode terminals, a main body that holds the connection member, and an insulating cover that covers the connection member. An insulation protector, and a routing route that is routed along the connection member and that is routed along the connection member bypasses the connection member and the insulation cover. An electric wire passed between them, and the electric wire passed between the connecting member and the insulating cover is covered with an insulating protective member.

本構成によれば、絶縁性の保護部材で覆われた電線が接続部材と絶縁カバーとの間に通されているため、絶縁カバーの外面側に電線を通す場合と比較して電線の離脱が生じにくい。よって、絶縁カバーに電線のガイド部や仮係止構造を設けなくても電線の離脱を防止できるため、簡素な構成で絶縁カバーに電線のガイド部の孔等を設けることによる絶縁性の低下を抑制することができる。
また、絶縁カバーに電線のガイド部や仮係止構造を設けなくてもよいため、絶縁カバー等を形成するための金型を簡略化することが可能になる。 According to this configuration, since the electric wire covered with the insulating protective member is passed between the connecting member and the insulating cover, the electric wire is detached compared to the case where the electric wire is passed through the outer surface side of the insulating cover. Hard to occur. Therefore, it is possible to prevent the detachment of the electric wire without providing an electric wire guide portion or a temporary locking structure on the insulating cover. Therefore, the insulation property can be reduced by providing a hole or the like of the electric wire guide portion in the insulating cover with a simple configuration. Can be suppressed.
Moreover, since it is not necessary to provide the guide part of the electric wire and the temporary locking structure on the insulating cover, it is possible to simplify the mold for forming the insulating cover and the like.

上記構成に加えて以下の構成を有すれば好ましい。
・前記電線は、導体部が絶縁被覆で覆われた被覆電線であり、前記被覆電線が前記保護部材で覆われている。
このようにすれば、電線の絶縁被覆とは別に絶縁性の保護部材が設けられるため、電線の絶縁被覆のみを保護部材とする場合と比較して確実に電線を保護することができる。 In addition to the above configuration, the following configuration is preferable.
-The said electric wire is a covered electric wire with which the conductor part was covered with the insulation coating, and the said covered electric wire is covered with the said protection member.
In this case, since the insulating protective member is provided separately from the insulating coating of the electric wire, the electric wire can be reliably protected as compared with the case where only the insulating coating of the electric wire is used as the protective member.

・前記蓄電素子の状態を検知するための検知端子を備え、前記検知端子に前記電線が接続されている。 A detection terminal for detecting the state of the electricity storage element is provided, and the electric wire is connected to the detection terminal.

本発明によれば、簡素な構成で絶縁性の低下を抑制することが可能となる。また、絶縁カバーに電線のガイド部や仮係止構造を設けなくてもよいため、絶縁カバー等を形成するための金型を簡略化することが可能になる。   According to the present invention, it is possible to suppress a decrease in insulation with a simple configuration. Moreover, since it is not necessary to provide the guide part of the electric wire and the temporary locking structure on the insulating cover, it is possible to simplify the mold for forming the insulating cover and the like.

（絶縁カバー３１）
絶縁カバー３１は、長尺接続部材１６Ａを覆う閉鎖位置に回動可能とされている（図３では、絶縁カバー３１が長尺接続部材１６Ａを覆わない開放状態を示す）。 (Insulation cover 31)
The insulating cover 31 can be rotated to a closed position that covers the long connecting member 16A (in FIG. 3, the insulating cover 31 shows an open state in which the long connecting member 16A is not covered).

絶縁カバー３１は、左右方向に長い板状であって、長尺接続部材１６Ａの左右方向の端部を除いたほぼ全体を覆う長さで設けられ、接続部材保持部２４Ａの後端部にヒンジ部３２を介して接続されている。   The insulating cover 31 has a plate shape that is long in the left-right direction, and is provided with a length that covers almost the whole of the long connecting member 16A except for the end in the left-right direction, and is hinged to the rear end of the connecting member holding portion 24A. They are connected via the part 32.

ヒンジ部３２は、薄肉の帯状に形成されることで可撓性を有し、本体２１及び絶縁カバー３１と一体に形成され、左右方向に間隔を空けて複数（本実施形態では３箇所）設けられている。
絶縁カバー３１におけるヒンジ部３２とは反対側の端縁には、左右方向に間隔を空けて複数（本実施形態では３個）の係止部３３が形成されている。 The hinge portion 32 is flexible by being formed in a thin strip shape, is formed integrally with the main body 21 and the insulating cover 31, and is provided with a plurality (three in this embodiment) at intervals in the left-right direction. It has been.
A plurality of (three in the present embodiment) locking portions 33 are formed on the edge of the insulating cover 31 opposite to the hinge portion 32 at intervals in the left-right direction.

係止部３３は、絶縁カバー３１の板面から起立する方向に突出しており、先端部に係止爪を有し、前後方向に撓み変形可能となっている。係止部３３は、絶縁カバー３１を接続部材保持部２４Ａに被せて長尺接続部材１６Ａを覆う閉鎖位置とした際に接続部材保持部２４Ａの係止孔３４Ａに挿通されて係止爪が係止孔３４Ａの孔縁に係止される。これにより、係止部３３が被係止部３４に係止され、絶縁カバー３１が閉鎖位置に保持される。   The locking portion 33 protrudes in a direction rising from the plate surface of the insulating cover 31, has a locking claw at the tip, and can be bent and deformed in the front-rear direction.

次に配線モジュール１５の組付けについて説明する。
絶縁プロテクタ２０の絶縁カバー３１を開放状態とし、接続部材保持部２４Ａ，２４Ｂに接続部材１６Ａ，１６Ｂを収容する（図３）。
次に、電線Ｗの端末部に接続された電圧検知端子１８を短尺接続部材１６Ｂに重ねて装着し、電線Ｗを電線配索部２８に配索する（図４）。
ここで、絶縁プロテクタ２０のうち、載置部２２Ａ側の電線Ｗが長尺接続部材１６Ａに沿う電線配索部２８に配索されて載置部２２Ｂ側に導かれるが、長尺接続部材１６Ａの中間部については、電線Ｗが電線配索部２８から長尺接続部材１６Ａの上方側に迂回するように通される。
このようにすることで、例えば、配置の制約等により、長尺接続部材１６Ａの側方に電線Ｗを通すことができない部分が存在する場合であっても、長尺接続部材１６Ａとの間の絶縁状態を確保しつつ、載置部２２Ａ側の電線Ｗを他方の載置部２２Ｂ側に導くことができる。
他方の載置部２２Ｂ側に導出された電線Ｗは、外部の電池ＥＣＵ等に導出される。 Next, assembly of the wiring module 15 will be described.
The insulating cover 31 of the insulating protector 20 is opened, and the connecting members 16A and 16B are accommodated in the connecting member holding portions 24A and 24B (FIG. 3).
Next, the voltage detection terminal 18 connected to the terminal portion of the electric wire W is mounted on the short connection member 16B so as to be routed, and the electric wire W is routed to the wire routing portion 28 (FIG. 4).
Here, in the insulation protector 20, the electric wire W on the mounting portion 22A side is routed to the electric wire routing portion 28 along the long connecting member 16A and guided to the mounting portion 22B side, but the long connecting member 16A. As for the intermediate portion, the electric wire W is passed from the electric wire routing portion 28 so as to bypass the long connecting member 16A.
By doing in this way, for example, even when there is a portion where the electric wire W cannot be passed to the side of the long connection member 16A due to arrangement restrictions or the like, it is between the long connection member 16A. The electric wire W on the mounting portion 22A side can be guided to the other mounting portion 22B side while ensuring an insulating state.
The electric wire W led out to the other mounting portion 22B side is led out to an external battery ECU or the like.

次に、絶縁カバー３１をヒンジ部３２を軸として長尺接続部材１６Ａと対向する側に回動させて絶縁カバー３１を長尺接続部材１６Ａを覆う閉鎖位置として係止部３３を被係止部３４に係止させる（図５）。   Next, the insulating cover 31 is pivoted about the hinge portion 32 to the side facing the long connecting member 16A, and the insulating portion 31 is used as a closed position covering the long connecting member 16A, so that the locking portion 33 is locked. 34 (FIG. 5).

また、補助カバー部３０を電線Ｗを覆う閉鎖位置に回動させて係止する（図６）。
これにより、配線モジュール１５が形成される。 Further, the auxiliary cover portion 30 is rotated and locked to a closed position covering the electric wire W (FIG. 6).
Thereby, the wiring module 15 is formed.

この配線モジュール１５を複数個の蓄電素子１１に載置し、接続部材１６Ａ，１６Ｂの挿通孔１７，１７にボルトを通して電極端子１３Ａ，１３Ｂに締結することで、蓄電モジュール１０が形成される（図１）。   The wiring module 15 is placed on the plurality of power storage elements 11 and fastened to the electrode terminals 13A and 13B through bolts through the insertion holes 17 and 17 of the connection members 16A and 16B, thereby forming the power storage module 10 (FIG. 1).

本実施形態によれば、以下の作用、効果を奏する。
本実施形態の配線モジュール１５は、正極及び負極の電極端子１３Ａ，１３Ｂを有する複数の蓄電素子１１における隣り合う電極端子１３Ａ，１３Ｂ間を接続する接続部材１６Ａと、接続部材１６Ａを保持する本体２１と接続部材１６Ａを覆う絶縁カバー３１とを有する絶縁プロテクタ２０と、絶縁プロテクタ２０に配索され、接続部材１６Ａと絶縁カバー３１との間に通される電線Ｗと、を備え、接続部材１６Ａと絶縁カバー３１との間に通された電線Ｗは、絶縁性の保護部材３５で覆われている。 According to this embodiment, the following operations and effects are achieved.
The wiring module 15 of the present embodiment includes a connecting member 16A that connects the adjacent electrode terminals 13A and 13B in the plurality of power storage elements 11 having the positive and negative electrode terminals 13A and 13B, and a main body 21 that holds the connecting member 16A. And an insulating protector 20 that covers the connecting member 16A, and an electric wire W that is routed between the connecting member 16A and the insulating cover 31, and is connected to the connecting member 16A. The electric wire W passed between the insulating cover 31 and the insulating cover 31 is covered with an insulating protective member 35.

本実施形態によれば、絶縁性の保護部材３５で覆われた電線Ｗが接続部材１６Ａと絶縁カバー３１との間に通されているため、絶縁カバー３１の外面側に電線Ｗを通す場合と比較して電線Ｗの離脱が生じにくい。よって、絶縁カバー３１に電線Ｗのガイド部や仮係止構造を設けなくても電線Ｗの離脱を防止できるため、簡素な構成で絶縁カバー３１に電線Ｗのガイド部の孔等を設けることによる絶縁性の低下を抑制することができる。
絶縁カバー３１に電線のガイド部や仮係止構造を設けなくてもよいため、絶縁カバー３１（絶縁プロテクタ２０）を形成するための金型を簡略化することが可能になる。 According to this embodiment, since the electric wire W covered with the insulating protective member 35 is passed between the connecting member 16A and the insulating cover 31, the electric wire W is passed through the outer surface side of the insulating cover 31. In comparison, detachment of the electric wire W is less likely to occur. Therefore, since the detachment of the electric wire W can be prevented without providing the insulating cover 31 with a guide portion or a temporary locking structure of the electric wire W, the insulating cover 31 is provided with a hole or the like of the guide portion of the electric wire W with a simple configuration. A decrease in insulation can be suppressed.
Since it is not necessary to provide the wire guide part and the temporary locking structure on the insulating cover 31, it is possible to simplify the mold for forming the insulating cover 31 (insulating protector 20).

また、電線Ｗは、導体部ＷＡが絶縁被覆ＷＢで覆われた被覆電線Ｗであり、被覆電線Ｗが保護部材３５で覆われている。
このようにすれば、電線Ｗの絶縁被覆ＷＢとは別に絶縁性の保護部材３５が設けられるため、電線Ｗの絶縁被覆ＷＢのみを保護部材３５とする場合と比較して確実に電線Ｗを保護することができる。 The electric wire W is a covered electric wire W in which the conductor portion WA is covered with an insulating coating WB, and the covered electric wire W is covered with a protective member 35.
In this case, since the insulating protective member 35 is provided separately from the insulating coating WB of the electric wire W, the electric wire W is reliably protected as compared with the case where only the insulating coating WB of the electric wire W is used as the protective member 35. can do.
