Description

本発明は、電気接続箱及びワイヤハーネスに関する。   The present invention relates to an electrical connection box and a wire harness.

従来、筐体等の内部に収容された電子部品のメンテナンス性を向上させる技術が知られている。例えば、下記の特許文献１及び２には、筐体内において開口の近くに電子部品を配置することで、電子部品のメンテナンス性を向上させた電気接続箱が開示されている。特許文献１の電気接続箱では、その開口を塞ぐ蓋を開けることによって、その開口の近くのヒュージブルリンク（電子部品）の溶断の確認を容易にしている。特許文献２の電気接続箱では、その開口を塞ぐカバーを開けることによって、その開口の近くのヒューズ（電子部品）の交換を容易にしている。しかしながら、これらの電気接続箱においては、筐体内における開口から離れた場所に電子部品を配置した場合、その電子部品のメンテナンス性が低下してしまうので、同一空間内での電子部品の高密度な収容が難しい。下記の特許文献３及び４に記載の電気接続箱は、電子部品のメンテナンス性と収容性の向上を図るべく構成されたものである。この電気接続箱においては、リレーやヒューズ等の電子部品と当該電子部品の保持部材（ブロック）との接続体を筐体内で上下２段に重ねて配置している。尚、下記の特許文献５には、上段の接続体を成す保持部材に下段の接続体を取り付ける技術が開示されている。   BACKGROUND Conventionally, there are known techniques for improving the maintainability of electronic components housed in a housing or the like. For example, Patent Documents 1 and 2 below disclose an electrical connection box in which the maintainability of the electronic component is improved by arranging the electronic component near the opening in the housing. In the electrical connection box of Patent Document 1, by opening a lid that closes the opening, confirmation of melting of the fusible link (electronic component) near the opening is facilitated. In the electrical connection box of Patent Document 2, replacement of the fuse (electronic component) near the opening is facilitated by opening a cover that closes the opening. However, in these electrical connection boxes, if the electronic components are disposed at a position away from the opening in the housing, the maintainability of the electronic components is reduced, so the density of the electronic components in the same space is high. Containment is difficult. The electric connection boxes described in Patent Documents 3 and 4 below are configured to improve the maintainability and the accommodation of electronic components. In this electrical connection box, a connecting body of an electronic component such as a relay or a fuse and a holding member (block) of the electronic component is arranged in two layers in the upper and lower stages in a casing. Patent Document 5 below discloses a technique for attaching the lower connection body to a holding member forming the upper connection body.

特開２００４−２１５４２２号公報JP, 2004-215422, A 特開２００８−１１３５３４号公報JP, 2008-113534, A 特開２００９−２７８８００号公報JP, 2009-278800, A 特開２０１１−１０５１４号公報JP, 2011-10514, A 特開２０１３−２２３３６７号公報JP, 2013-223367, A

ところで、特許文献３の電気接続箱は、筐体の上部の開口（メンテナンス作業用の開口）から上段の接続体と下段の接続体を着脱させる構造を採っている。このため、上段の接続体を筐体へと組み付ける際には、上段の接続体の下部から引き出されている電線（電子部品に直接的又は間接的に電気接続されている電線）を、先に筐体内に収容されている下段の接続体を避けながら配索作業する必要がある。一方、特許文献４の電気接続箱は、筐体の上部の開口から上段の接続体を着脱させ、かつ、筐体の下部の開口から下段の接続体を着脱させる構造を採っている。このため、この電気接続箱は、先に上段の接続体を筐体内に収容した後で、下段の接続体を下部の開口から収容することができるので、下段の接続体を避けながらの上段の電線の配索作業を回避することができる。しかしながら、この電気接続箱は、上段の接続体を筐体へと組み付ける際に、上段の長尺の電線を先に筐体内に挿入し、その後で上段の接続体を筐体内に収容しなければならないので、組付け作業性について改善の余地がある。   By the way, the electrical connection box of Patent Document 3 adopts a structure in which the upper connection body and the lower connection body are attached and detached from the opening (opening for maintenance work) of the upper portion of the housing. For this reason, when assembling the upper connection body into the housing, the electric wire drawn from the lower portion of the upper connection body (electric wire directly or indirectly connected to the electronic component) is first It is necessary to carry out the wiring work while avoiding the lower connection body accommodated in the housing. On the other hand, the electrical connection box of Patent Document 4 adopts a structure in which the upper connection body is attached and detached from the opening in the upper part of the housing, and the lower connection body is attached and detached from the opening in the lower part of the housing. For this reason, since this electrical connection box can accommodate the lower connection body from the lower opening after the upper connection body is accommodated in the housing first, the upper connection line can be avoided while avoiding the lower connection body. It is possible to avoid the wiring work of the electric wire. However, in this electrical connection box, when the upper connection body is assembled to the housing, the upper electric wire is first inserted into the housing, and then the upper connection body is not accommodated in the housing. Because there is no room for improvement in the assembling workability.

そこで、本発明は、電子部品の良好なメンテナンス性と収容性と組付け作業性とを得ることのできる電気接続箱と、このような電気接続箱を備えたワイヤハーネスと、を提供することを目的とする。   Therefore, the present invention provides an electrical connection box capable of obtaining good maintainability, accommodation and assembly workability of electronic parts, and a wire harness including such an electrical connection box.

端子２２は、金属等の導電性材料によって構成される。例えば、端子２２は、電子部品本体２１と電気的に接続されている金属製のバスバーの一部として形成されている。この端子２２は、金属製の相手側端子（図示略）と着脱自在に且つ電気的に接続される。この端子２２と相手側端子は、一方が雄型に成形され、他方が雌型に成形される。この例示では、端子２２を雄型に成形し、相手側端子を雌型に成形している。その相手側端子は、電子部品保持部材３０の内部に収容されている。この例示の電子部品２０においては、４つの端子２２を電子部品本体２１から同一方向に向けて延出させている。   The terminal 22 is made of a conductive material such as metal. For example, the terminal 22 is formed as a part of a metal bus bar electrically connected to the electronic component body 21. The terminal 22 is detachably and electrically connected to a metal counterpart terminal (not shown). One of the terminal 22 and the other terminal is molded into a male mold, and the other is molded into a female mold. In this example, the terminal 22 is molded into a male mold, and the mating terminal is molded into a female mold. The mating terminal is housed inside the electronic component holding member 30. In the illustrated electronic component 20, four terminals 22 extend from the electronic component body 21 in the same direction.

電子部品保持部材３０は、合成樹脂等の絶縁性材料によって成形される。この電子部品保持部材３０には、電子部品２０の端子２２を個別に収容する収容室（以下、「端子収容室」という。）３１が形成されている。本実施形態の接続体１０においては、その端子収容室３１への端子２２の挿入方向を全て同じ向きに合わせている。   The electronic component holding member 30 is formed of an insulating material such as a synthetic resin. In the electronic component holding member 30, a storage chamber (hereinafter referred to as a "terminal storage chamber") 31 for storing the terminals 22 of the electronic component 20 individually is formed. In the connection body 10 of the present embodiment, the insertion directions of the terminals 22 into the terminal accommodation chambers 31 are all the same.

端子収容室３１には、上記の相手側端子が嵌合される。電子部品２０は、端子２２を相手側端子の接続部に挿入することで、この相手側端子に保持される。このため、電子部品保持部材３０においては、この端子収容室３１に電子部品２０の端子２２を収容しつつ、この電子部品２０が保持される。尚、電子部品保持部材３０には、端子収容室３１と共に、電子部品本体２１の収容室を形成してもよい。この場合、電子部品２０は、その電子部品本体２１の収容室に保持させることができる。   The other terminal described above is fitted in the terminal accommodating chamber 31. The electronic component 20 is held by the mating terminal by inserting the terminal 22 into the connection portion of the mating terminal. Therefore, in the electronic component holding member 30, the electronic component 20 is held while the terminal 22 of the electronic component 20 is accommodated in the terminal accommodation chamber 31. In the electronic component holding member 30, a housing chamber of the electronic component main body 21 may be formed together with the terminal housing chamber 31. In this case, the electronic component 20 can be held in the storage chamber of the electronic component body 21.

ここで、相手側端子には、電線４０が電気的に接続される。例えば、電線４０は、相手側端子における端子２２との接続部とは反対側に圧着させる。この場合には、電線４０の圧着された相手側端子を、電子部品保持部材３０における端子２２の挿入口とは逆側から端子収容室３１に挿入して、この端子収容室３１に嵌合させる。また、電線４０は、その端部に電線用端子（図示略）を電気接続し、この電線用端子を相手側端子に接続することによって、相手側端子との電気的な接続を構築してもよい。この場合、相手側端子には、端子２２との接続部とは反対側に、電線用端子との接続部が形成される。電線４０は、このように、相手側端子を介して、電子部品２０の端子２２に電気的に接続される。   Here, the electric wire 40 is electrically connected to the other terminal. For example, the electric wire 40 is crimped to the opposite side to the connection part with the terminal 22 in the other party terminal. In this case, the crimped counterpart terminal of the electric wire 40 is inserted into the terminal accommodating chamber 31 from the side opposite to the insertion opening of the terminal 22 in the electronic component holding member 30 and fitted in the terminal accommodating chamber 31 . Also, the electric wire 40 electrically connects the electric wire terminal (not shown) to the end thereof, and connects the electric wire terminal to the other side terminal to establish an electric connection with the other side terminal. Good. In this case, a connection portion with the wire terminal is formed on the opposite side of the mating terminal on the opposite side to the connection portion with the terminal 22. The electric wire 40 is thus electrically connected to the terminal 22 of the electronic component 20 via the other-side terminal.

本実施形態の電気接続箱１は、そのように構成した接続体１０を複数備えている。その複数の接続体１０は、互いに間隔を空けた積層状態で筐体６０の内部に収容する。複数の接続体１０の積層方向としては、例えば、車両上下方向や車両前後方向等、電気接続箱１の配置に応じた様々な方向が考えられる。   The electrical connection box 1 of the present embodiment includes a plurality of connection bodies 10 configured as described above. The plurality of connectors 10 are housed inside the housing 60 in a stacked state in which the plurality of connectors 10 are spaced apart from each other. As the stacking direction of the plurality of connectors 10, for example, various directions according to the arrangement of the electrical connection box 1, such as the vertical direction of the vehicle and the longitudinal direction of the vehicle, can be considered.

筐体６０は、合成樹脂等の絶縁性材料によって成形される。この筐体６０には、積層された複数の接続体１０の収容が可能な収容室（以下、「接続体収容室」という。）６１が形成されている。その接続体収容室６１は、複数の接続体１０の積層方向における両端に開口部６１ａ，６１ｂを有する。それぞれの開口部６１ａ，６１ｂは、接続体１０の接続体収容室６１への挿入と接続体収容室６１からの抜去とが行える大きさと形状に形成する。それぞれの開口部６１ａ，６１ｂの内の少なくとも一方は、接続体１０のメンテナンス作業時の作業用開口部として利用する。この例示では、一方の開口部６１ａを作業用開口部として利用する。メンテナンス作業とは、例えば、電子部品２０や電線４０の状態の確認作業（ヒューズの溶断の有無の確認等）、電子部品２０の交換作業などのことである。このため、最も作業用開口部に近い接続体１０は、電子部品２０を作業用開口部から露出させた状態で接続体収容室６１に収容する。これにより、作業者は、例えば、この接続体１０を筐体６０に保持させたままで、この接続体１０の電子部品２０のメンテナンス作業を作業用開口部側から行うことができる。この接続体１０の電子部品２０は、作業用開口部よりも接続体収容室６１の内方に配置してもよく、図１に示すように、作業用開口部から接続体収容室６１の外に突出させてもよい。一方、他の接続体１０については、電子部品２０における電子部品本体２１が作業用開口部側を向くように接続体収容室６１の中に配置する。これにより、作業者は、この接続体１０に重なっている作業用開口部側の接続体１０を接続体収容室６１から取り外した場合、この取り外しに伴い露出した接続体収容室６１の中の電子部品２０のメンテナンス作業を作業用開口部側から行うことができる。   The housing 60 is formed of an insulating material such as a synthetic resin. In the housing 60, a storage chamber (hereinafter, referred to as a "connection body storage chamber") 61 in which a plurality of stacked connection bodies 10 can be stored is formed. The connector housing chamber 61 has openings 61 a and 61 b at both ends in the stacking direction of the plurality of connectors 10. Each of the openings 61 a and 61 b is formed in a size and a shape that allows the connection body 10 to be inserted into the connection body storage chamber 61 and removed from the connection body storage chamber 61. At least one of the openings 61 a and 61 b is used as a work opening at the time of maintenance work of the connector 10. In this example, one opening 61a is used as a work opening. The maintenance operation is, for example, an operation of confirming the state of the electronic component 20 or the electric wire 40 (a confirmation of the presence or absence of melting of a fuse, etc.), an operation of replacing the electronic component 20, and the like. For this reason, the connector 10 closest to the work opening is accommodated in the connector storage chamber 61 with the electronic component 20 exposed from the work opening. Thereby, the worker can perform maintenance work of the electronic component 20 of the connection body 10 from the work opening while keeping the connection body 10 in the housing 60, for example. The electronic component 20 of the connection body 10 may be disposed inward of the connection body accommodation chamber 61 than the working opening, and as shown in FIG. 1, the outside of the connection body accommodation chamber 61 from the working opening. You may make it project. On the other hand, the other connector 10 is disposed in the connector accommodating chamber 61 so that the electronic component body 21 of the electronic component 20 faces the work opening. Thus, when the worker removes the connection body 10 on the side of the work opening overlapping the connection body 10 from the connection body storage chamber 61, the electrons in the connection body storage chamber 61 exposed along with the removal are removed. The maintenance work of the part 20 can be performed from the work opening side.

FIG. 8 is a top view (a view from the side of the opening 61 a) showing a state in which the first connection body 10 </ b> A is assembled to the connection body storage chamber 61. On the other hand, in the other connecting member holding mechanism 72 in the side wall surfaces 32a and 32b, the first engaging portion 72A extends from the U-shaped opening portion in the second engaging portion 72B and the two arm portions 72B 1 and It is inserted in a space surrounded by the shaft portion 72B 2.

第１係合部７２Ａの乗り越えの際、第２係合部７２Ｂは、第１係合部７２Ａからの力が軸部７２Ｂ２に加わり、内壁面６２ａ，６２ｂから離れていく方向へと傾倒する。この第２係合部７２Ｂは、空間内に第１係合部７２Ａが挿入されると、この第１係合部７２Ａからの力が解放されるので、元の位置に戻る。側壁面３２ａと内壁面６２ａとの間の２つの接続体保持機構７２では、第１接続体１０Ａが積層方向の内の一方に動こうとしたときに、一方の接続体保持機構７２において係合面７２Ａ１が軸部７２Ｂ２で係止され、第１接続体１０Ａが積層方向の内の他方に動こうとしたときに、他方の接続体保持機構７２において係合面７２Ａ１が軸部７２Ｂ２で係止される。このような係合面７２Ａ１と軸部７２Ｂ２との間の係止状態は、側壁面３２ｂと内壁面６２ｂとの間の２つの接続体保持機構７２においても同様に起こっている。このため、第１接続体１０Ａは、開口部６１ａ側にも開口部６１ｂ側にも抜け出ることができず、接続体収容室６１に保持される。 Upon overcoming of the first engagement portion 72A, the second engagement portion 72B, the force from the first engagement portion 72A is applied to the shaft portion 72B 2, tilted in a direction away from the inner wall surface 62a, 62b . When the first engaging portion 72A is inserted into the space, the second engaging portion 72B returns to its original position because the force from the first engaging portion 72A is released. In the two connector holding mechanisms 72 between the side wall surface 32a and the inner wall surface 62a, when the first connector 10A tries to move in one of the stacking directions, the one connector holding mechanism 72 engages. surface 72A 1 is locked by the shaft portion 72B 2, when the first connecting member 10A is going to move to the other of the stacking direction, the engagement surface 72A 1 at the other connecting body holding mechanism 72 is the shaft portion 72B It is locked at 2 . Locked state between such engagement surface 72A 1 and the shaft portion 72B 2 is going to same in the two connecting body holding mechanism 72 between the side wall surface 32b and the inner wall surface 62b. For this reason, the first connection body 10A can not be pulled out to either the opening 61a side or the opening 61b side, and is held in the connection body storage chamber 61.

接続体保持機構７２においては、そのロック状態を解除する場合、マイナスドライバの如き治具で軸部７２Ｂ２を接続体収容室６１の内壁面６２ａ，６２ｂ側に押し動かして、係合面７２Ａ１が軸部７２Ｂ２で係止されないようにすればよい。 In connection body holding mechanism 72, when releasing the locked state, the inner wall surface 62a of the connector accommodating chamber 61 to the shaft portion 72B 2 in such jig screwdriver, moving push 62b side, the engaging surfaces 72A 1 There may be as not locked in the shaft portion 72B 2.

第１接続体１０Ａは、これら４つの接続体保持機構７２によって、接続体収容室６１に対する他方の開口部６１ｂ側から作業用開口部（一方の開口部６１ａ）側への着脱と、作業用開口部側から他方の開口部６１ｂ側への着脱と、を行うことができる。このため、第１接続体１０Ａは、開口部６１ｂ側から接続体収容室６１に挿入し、この接続体収容室６１に保持することができる。また、第１接続体１０Ａは、開口部６１ｂ側から抜き出したい場合、開口部６１ｂ側で係止している軸部７２Ｂ２を押し動かして、接続体保持機構７２のロック状態を解除することによって、開口部６１ｂ側から取り外すことができる。一方、第１接続体１０Ａは、開口部６１ａ側から抜き出したい場合、開口部６１ａ側で係止している軸部７２Ｂ２を押し動かして、接続体保持機構７２のロック状態を解除することによって、開口部６１ａ側から取り外すことができる。また、第１接続体１０Ａは、開口部６１ａ側から接続体収容室６１に挿入し、この接続体収容室６１に保持することができる。このため、作業者は、作業用開口部から取り外してメンテナンス作業を行った第１接続体１０Ａを、電気接続箱１を車両から取り外さなくても、接続体収容室６１に再び戻すことができる。このように、第１接続体１０Ａは、どちらの開口部６１ａ，６１ｂからも着脱することができる。従って、この電気接続箱１は、第１接続体１０Ａのメンテナンス作業性に優れている。 The first connection body 10A is attached and detached from the other opening 61b side with respect to the connection body storage chamber 61 by the four connection body holding mechanisms 72 to the work opening (one opening 61a) side, and the work opening It is possible to perform attachment and detachment from the side of the part to the side of the other opening 61b. Therefore, the first connection body 10A can be inserted into the connection body storage chamber 61 from the opening 61b side, and can be held in the connection body storage chamber 61. Further, by first connecting member 10A, when want to extract from the opening 61b side, which move down the shaft portion 72B 2 are locked at the opening 61b side to release the locked state of the connector retention mechanism 72 , Can be removed from the opening 61b side. On the other hand, by a first connecting member 10A, when want to extract from the opening 61a side, which move down the shaft portion 72B 2 which is locked by the opening 61a side to release the locked state of the connector retention mechanism 72 , Can be removed from the opening 61a side. Further, the first connection body 10A can be inserted into the connection body storage chamber 61 from the opening 61a side and can be held in the connection body storage chamber 61. For this reason, the worker can return the first connection body 10A removed from the work opening and subjected to the maintenance work back to the connection body accommodation chamber 61 without removing the electric connection box 1 from the vehicle. Thus, the first connection body 10A can be attached and detached from either of the openings 61a and 61b. Therefore, the electrical connection box 1 is excellent in the maintenance workability of the first connection body 10A.

ここで、電子部品保持部材３０Ａの側壁面３２ａ，３２ｂには、各々、並列配置された２つの第１係合部７２Ａを挟み込むように、接続体１０の積層方向に延在させた第１ガイド部８１を設けている（図３、図４、図８）。この例示の第１ガイド部８１は、側壁面３２ａ，３２ｂの面上から突出させている。更に、接続体収容室６１の内壁面６２ａ，６２ｂには、各々、並列配置された２つの第２係合部７２Ｂを挟み込むように、接続体１０の積層方向に延在させた第２ガイド部８２を設けている（図７−図９）。この例示の第２ガイド部８２は、内壁面６２ａ，６２ｂの面上から突出させている。第１ガイド部８１と第２ガイド部８２は、互いに嵌合状態で相手を積層方向に案内するものである。これにより、作業者は、第１接続体１０Ａの接続体収容室６１に対する着脱作業を容易に行うことができる。   Here, a first guide extending in the stacking direction of the connector 10 so as to sandwich the two first engaging portions 72A arranged in parallel on the side wall surfaces 32a and 32b of the electronic component holding member 30A. The part 81 is provided (FIG. 3, FIG. 4, FIG. 8). The illustrated first guide portion 81 protrudes from above the side wall surfaces 32a and 32b. Furthermore, a second guide portion extended in the stacking direction of the connector 10 so as to sandwich the two second engaging portions 72B arranged in parallel on the inner wall surfaces 62a and 62b of the connector accommodating chamber 61 respectively. 82 are provided (FIGS. 7-9). The second guide portion 82 of this example is projected from the surface of the inner wall surfaces 62a and 62b. The first guide portion 81 and the second guide portion 82 guide each other in the stacking direction in a fitted state. As a result, the worker can easily carry out the attachment / detachment operation of the first connection body 10A with respect to the connection body storage chamber 61.

次に、他方の開口部６１ｂ側に配置される第２接続体１０Ｂについて説明する。この第２接続体１０Ｂは、接続体保持部材７１を介して接続体収容室６１に間接的に保持させる。このため、接続体保持部材７１と接続体収容室６１との間には、保持部材保持機構７３を設ける。更に、第２接続体１０Ｂと接続体保持部材７１との間には、接続体保持機構７４を設ける。   Next, the second connection body 10B disposed on the other opening 61b side will be described. The second connector 10 B is indirectly held by the connector accommodating chamber 61 via the connector holding member 71. For this reason, a holding member holding mechanism 73 is provided between the connection member holding member 71 and the connection member accommodation chamber 61. Furthermore, a connection body holding mechanism 74 is provided between the second connection body 10B and the connection body holding member 71.

先に、接続体保持部材７１と接続体保持機構７４について説明する。   First, the connection body holding member 71 and the connection body holding mechanism 74 will be described.

接続体保持部材７１は、接続体１０を収容し且つ保持する接続体収容室を少なくとも１つ備える。この例示の接続体保持部材７１は、図１１に示すように、第２接続体１０Ｂが収容される接続体収容室７１Ａを１つ備える。図１１は、接続体収容室６１に収容された接続体保持部材７１を開口部６１ｂ側から見た下面図である。接続体収容室７１Ａは、第２接続体１０Ｂの形状に合わせて、４つの側壁部７１ａ，７１ｂ，７１ｃ，７１ｄで囲まれた方体状の内部空間として形成する。但し、本実施形態の接続体保持部材７１には、第２接続体１０Ｂ以外の接続体１０（第１接続体１０Ａ）の電線４０を案内するための後述する電線挿通路Ｐを形成すべく、側壁部７１ｂと側壁部７１ｃとの間に凹部７１ｅを設ける（図２及び図１５）。   The connector holding member 71 includes at least one connector housing chamber for housing and holding the connector 10. The illustrated connection body holding member 71 includes one connection body accommodation chamber 71A in which the second connection body 10B is accommodated, as shown in FIG. FIG. 11 is a bottom view of the connection body holding member 71 accommodated in the connection body accommodation chamber 61 as viewed from the opening 61 b side. The connector housing chamber 71A is formed as a rectangular internal space surrounded by the four side wall portions 71a, 71b, 71c, and 71d in accordance with the shape of the second connector 10B. However, in order to form an electric wire insertion path P described later for guiding the electric wire 40 of the connection body 10 (first connection body 10A) other than the second connection body 10B in the connection body holding member 71 of the present embodiment, A recess 71e is provided between the side wall 71b and the side wall 71c (FIGS. 2 and 15).

接続体収容室７１Ａにおいては、４つの側壁部７１ａ，７１ｂ，７１ｃ，７１ｄの端部で囲まれた一方の開口部７１ｆを第２接続体１０Ｂの挿入及び抜去に利用する。その開口部７１ｆは、接続体収容室６１に収容された際に、開口部６１ｂ側に配置される。このため、第２接続体１０Ｂは、接続体１０の積層方向に沿って、接続体収容室７１Ａに着脱される。尚、接続体収容室７１Ａに対する第２接続体１０Ｂの挿入及び抜去の方向は、必ずしも積層方向に沿わせなくてもよい。   In the connector housing chamber 71A, one opening 71f surrounded by the end portions of the four side wall portions 71a, 71b, 71c, and 71d is used for inserting and removing the second connector 10B. The opening 71 f is disposed on the side of the opening 61 b when the opening 71 f is accommodated in the connection member accommodation chamber 61. For this reason, the second connection body 10B is attached to and detached from the connection body accommodation chamber 71A along the stacking direction of the connection body 10. The direction of insertion and removal of the second connection body 10B with respect to the connection body accommodating chamber 71A may not necessarily be along the stacking direction.

この例示の接続体収容室７１Ａにおいては、４つの側壁部７１ａ，７１ｂ，７１ｃ，７１ｄで囲まれた他方の開口部を塞ぐ仕切り壁部７１ｇを設けている。仕切り壁部７１ｇは、積層状態の第１接続体１０Ａと第２接続体１０Ｂとの間に配置された間仕切りである。この仕切り壁部７１ｇは、接続体保持部材７１に必須の構成ではないが、組付け時に第１接続体１０Ａの電線４０の接続体収容室７１Ａへの進入を防ぐことができるので、接続体保持部材７１に設けておくことが望ましい。   In the illustrated connector housing chamber 71A, a partition wall 71g is provided to close the other opening surrounded by the four side walls 71a, 71b, 71c, 71d. The partition wall portion 71g is a partition disposed between the first connection body 10A and the second connection body 10B in a stacked state. The partition wall portion 71g is not an essential component for the connection member holding member 71, but can prevent the wire 40 of the first connection member 10A from entering the connection member storage chamber 71A at the time of assembly. It is desirable to provide it on the member 71.

接続体保持機構７４は、第２接続体１０Ｂと４つの側壁部７１ａ，７１ｂ，７１ｃ，７１ｄの内の少なくとも２つとの間に配置する。この例示では、互いに対向している電子部品保持部材３０Ｂの側壁面３３ａと側壁部７１ａの内壁面との間、互いに対向している電子部品保持部材３０Ｂの側壁面３３ｂと側壁部７１ｂの内壁面との間、及び、互いに対向している電子部品保持部材３０Ｂの側壁面３３ｄと側壁部７１ｄの内壁面との間に、接続体保持機構７４を１つずつ配置している（図６、図１１、図１２）。図１２は、第２接続体１０Ｂが接続体収容室７１Ａに組み付けられた状態を示す下面図（接続体収容室６１に収容された際に開口部６１ｂ側から見た図）である。   The connection body holding mechanism 74 is disposed between the second connection body 10B and at least two of the four side wall portions 71a, 71b, 71c, and 71d.

第２係合部７４Ｂは、第２接続体１０Ｂの３つの第１係合部７４Ａと各々対向する位置に配置する。第２係合部７４Ｂは、側壁部７１ａ，７１ｂ，７１ｄのそれぞれの内壁面の面上から突出させた係合爪であり、第１係合部７４Ａとの間で係合される係合面７４Ｂ１を備える（図１３及び図１４）。その係合面７４Ｂ１は、第２接続体１０Ｂが接続体収容室７１Ａに収容されたときに第１係合部７４Ａの係合面７４Ａ１と対向する面である。 The second engaging portions 74B are disposed at positions facing the three first engaging portions 74A of the second connector 10B. The second engaging portion 74B is an engaging claw that protrudes from the surface of the inner wall surface of each of the side wall portions 71a, 71b, 71d, and is an engaging surface engaged with the first engaging portion 74A. 74B 1 (FIGS. 13 and 14). Part engaging surface 74B 1 is a surface facing the engaging surface 74A 1 of the first engagement portion 74A when the second connector 10B is accommodated in the connector housing chamber 71A.

更に、電子部品保持部材３０Ｂの側壁面３３ａ，３３ｂ，３３ｄには、各々、第１係合部７４Ａを挟み込むように、接続体１０の積層方向に延在させた第１ガイド部８５を設けている（図５、図６、図１２）。この例示の第１ガイド部８５は、側壁面３３ａ，３３ｂ，３３ｄの面上から突出させている。更に、接続体収容室７１Ａにおける側壁部７１ａ，７１ｂ，７１ｄのそれぞれの内壁面には、各々、第２係合部７４Ｂを挟み込むように、接続体１０の積層方向に延在させた第２ガイド部８６を設けている（図１１−図１４）。この例示の第２ガイド部８６は、その内壁面の面上から突出させている。第１ガイド部８５と第２ガイド部８６は、互いに嵌合状態で相手を積層方向に案内するものである。これにより、作業者は、第２接続体１０Ｂの接続体収容室７１Ａに対する着脱作業を容易に行うことができる。ここで、第２ガイド部８６における仕切り壁部７１ｇ側の端部には、案内されてきた第１ガイド部８５の端部を係止する係止部８７が形成されている（図１１、図１３、図１４）。   Furthermore, the side walls 33a, 33b and 33d of the electronic component holding member 30B are provided with a first guide portion 85 extended in the stacking direction of the connector 10 so as to sandwich the first engaging portion 74A. (FIG. 5, FIG. 6, FIG. 12). The illustrated first guide portion 85 is projected from the surface of the side wall surfaces 33a, 33b, 33d. Furthermore, on the inner wall surfaces of the side wall portions 71a, 71b, 71d in the connection body accommodation chamber 71A, a second guide extending in the stacking direction of the connection body 10 so as to sandwich the second engagement portion 74B. The part 86 is provided (FIGS. 11-14). The second guide portion 86 in this example is projected from the surface of the inner wall surface. The first guide portion 85 and the second guide portion 86 guide each other in the stacking direction in a fitted state. As a result, the worker can easily carry out the attaching / detaching operation of the second connector 10B with respect to the connector storage chamber 71A. Here, a locking portion 87 for locking the end portion of the guided first guide portion 85 is formed at the end portion of the second guide portion 86 on the side of the partition wall 71g (FIG. 11, FIG. 13, FIG. 14).

それぞれの接続体保持機構７４においては、開口部７１ｆからの第２接続体１０Ｂの接続体収容室７１Ａへの挿入と共に、第１係合部７４Ａが第２係合部７４Ｂを乗り越えて、第１係合部７４Ａと第２係合部７４Ｂとが係合されたロック状態になる（図１２及び図１４）。ここで、第１係合部７４Ａは、係合面７４Ａ１を有する部分が側壁面３３ａ，３３ｂ，３３ｄに対して浮いており、側壁面３３ａ，３３ｂ，３３ｄ側に力を加えることで傾倒させることができる。このため、第２接続体１０Ｂの挿入時には、第２係合部７４Ｂからの力で第１係合部７４Ａが側壁面３３ａ，３３ｂ，３３ｄ側に傾倒しながら、この第１係合部７４Ａが第２係合部７４Ｂを乗り越えていく。第１係合部７４Ａは、第２係合部７４Ｂを乗り越えた後、元の位置に戻る。そのロック状態での接続体保持機構７４においては、第１係合部７４Ａと第２係合部７４Ｂのそれぞれの係合面７４Ａ１，７４Ｂ１が向かい合い、かつ、互いに当接している。このため、第２接続体１０Ｂは、開口部７１ｆから抜け出ないように接続体収容室７１Ａに保持される。更に、この係合面７４Ａ１，７４Ｂ１同士のロック状態においては、第２接続体１０Ｂが仕切り壁部７１ｇ側に動こうとしても、第２接続体１０Ｂの第１ガイド部８５の端部が接続体収容室７１Ａの係止部８７によって係止されるので、仕切り壁部７１ｇ側への第２接続体１０Ｂの抜けも防ぐことができる。尚、第２接続体１０Ｂを接続体収容室７１Ａから取り外す際には、マイナスドライバの如き治具で第１係合部７４Ａを側壁面３３ａ，３３ｂ，３３ｄ側に押し動かせばよい。 In each connection body holding mechanism 74, the first engagement portion 74A passes over the second engagement portion 74B as the second connection body 10B is inserted into the connection body accommodation chamber 71A from the opening 71f. The engagement portion 74A and the second engagement portion 74B are engaged in a locked state (FIGS. 12 and 14). Here, the first engagement portion 74A is a partial side wall surface 33a having engagement surfaces 74A 1, 33b, and floats with respect to 33d, is inclined by applying a force side wall surfaces 33a, 33b, the 33d side be able to. Therefore, when the second connector 10B is inserted, the first engaging portion 74A is inclined while the first engaging portion 74A is inclined toward the side wall surfaces 33a, 33b, and 33d by the force from the second engaging portion 74B. It gets over the second engagement portion 74B. The first engaging portion 74A returns to the original position after crossing over the second engaging portion 74B. In the connector holding mechanism 74 in the locked state, the engagement surfaces 74A 1 and 74B 1 of the first engagement portion 74A and the second engagement portion 74B face each other and abut on each other. For this reason, the second connection body 10B is held in the connection body accommodation chamber 71A so as not to get out of the opening 71f. Furthermore, in the locked state of the engagement surfaces 74A 1 and 74B 1 , even if the second connector 10B tries to move to the partition wall 71 g side, the end of the first guide 85 of the second connector 10B is Since it is locked by the locking portion 87 of the connection body accommodation chamber 71A, it is possible to prevent the second connection body 10B from coming off to the side of the partition wall 71g. When the second connector 10B is removed from the connector housing chamber 71A, the first engaging portion 74A may be pushed toward the side wall surfaces 33a, 33b, 33d with a jig such as a minus driver.

第２接続体１０Ｂは、この接続体保持部材７１に保持された状態のまま、筐体６０の接続体収容室６１に収容され、かつ、この接続体収容室６１に保持部材保持機構７３によって保持される。   The second connector 10B is accommodated in the connector accommodating chamber 61 of the housing 60 while being held by the connector holding member 71, and is held in the connector accommodating chamber 61 by the holder holding mechanism 73. Be done.

保持部材保持機構７３には、接続体保持機構７２と同一構造のものを用いる。保持部材保持機構７３は、接続体保持部材７１に設けた第１係合部７３Ａと、接続体収容室６１の内壁面６２ｃ，６２ｄに設けた第２係合部７３Ｂと、を備える。   As the holding member holding mechanism 73, one having the same structure as the connection body holding mechanism 72 is used. The holding member holding mechanism 73 includes a first engagement portion 73A provided in the connection body holding member 71, and a second engagement portion 73B provided in the inner wall surfaces 62c and 62d of the connection body accommodation chamber 61.

第１係合部７３Ａは、内壁面６２ｃに対向する接続体保持部材７１の側壁部７１ｃの外壁面と、内壁面６２ｄに対向する接続体保持部材７１の側壁部７１ｄの外壁面と、に設ける（図１１及び図１２）。第１係合部７３Ａは、接続体保持機構７２の第１係合部７２Ａと同様の係合爪であり、第２係合部７３Ｂとの間で係合される係合面７３Ａ１を備える（図１１）。接続体保持部材７１のそれぞれの外壁面には、２つの第１係合部７３Ａが、接続体１０の積層方向に対する直交方向に並列配置される。その並列配置された２つの第１係合部７３Ａにおいては、一方の第１係合部７３Ａの係合面７３Ａ１が積層方向における一方側（開口部６１ａ側）に配置され、他方の第１係合部７３Ａの係合面７３Ａ１が積層方向における他方側（開口部６１ｂ側）に配置される。 The first engagement portion 73A is provided on the outer wall surface of the side wall portion 71c of the connection member holding member 71 facing the inner wall surface 62c and the outer wall surface of the side wall portion 71d of the connection member holding member 71 facing the inner wall surface 62d. (Figures 11 and 12). The first engagement portion 73A has a similar engaging claws and the first engagement portion 72A of the connector retention mechanism 72 includes engagement surfaces 73A 1 engaged with the second engagement portion 73B (Figure 11). The two first engaging portions 73A are arranged in parallel in the direction perpendicular to the stacking direction of the connection body 10 on each outer wall surface of the connection body holding member 71. In the two first engaging portions 73A arranged in parallel, the engaging surface 73A1 of one first engaging portion 73A is disposed on one side (opening 61a side) in the stacking direction, and the other first engaging surface 73A 1 of the engaging portion 73A is disposed on the other side in the stacking direction (the opening portion 61b side).

ここで、側壁部７１ｃ，７１ｄは、仕切り壁部７１ｇよりも開口部６１ａ側に延在させる。この例示では、側壁部７１ｃ，７１ｄを開口部６１ａの近くにまで延在させ、開口部６１ａ側の端部に第１係合部７３Ａを配置する。尚、第１接続体１０Ａは、仕切り壁部７１ｇよりも開口部６１ａ側の側壁部７１ｃ，７１ｄで挟み込まれている。   Here, the side wall portions 71c and 71d extend to the opening 61a side more than the partition wall 71g. In this example, the side wall portions 71c and 71d are extended to the vicinity of the opening 61a, and the first engaging portion 73A is disposed at the end on the opening 61a side. The first connector 10A is sandwiched between the side wall portions 71c and 71d closer to the opening 61a than the partition wall 71g.

第２係合部７３Ｂは、接続体保持機構７２の第２係合部７２Ｂと同様のロックアームであり、２つのアーム部７３Ｂ１と軸部７３Ｂ２とを備えたコの字状に形成される（図９及び図１０）。第２係合部７３Ｂは、接続体保持部材７１の４つの第１係合部７３Ａと各々対向する位置に配置する。第２係合部７３Ｂは、開口部６１ａ側に係合面７３Ａ１を有する第１係合部７３Ａを係合するものである場合、２つのアーム部７３Ｂ１における開口部６１ａ側の端部を軸部７３Ｂ２で繋ぎ、２つのアーム部７３Ｂ１における開口部６１ｂ側の端部を内壁面６２ｃ（６２ｄ）に固定する。これに対して、開口部６１ｂ側に係合面７３Ａ１を有する第１係合部７３Ａを係合するものである場合には、２つのアーム部７３Ｂ１における開口部６１ｂ側の端部を軸部７３Ｂ２で繋ぎ、２つのアーム部７３Ｂ１における開口部６１ａ側の端部を内壁面６２ｃ（６２ｄ）に固定する。 The second engagement portion 73B has the same lock arm and the second engaging portion 72B of the connector retention mechanism 72 is formed in the two arm portions 73B 1 and the shaft portion 73B 2 and U-shaped having a (Figures 9 and 10). The second engagement portions 73B are disposed at positions facing the four first engagement portions 73A of the connector holding member 71, respectively. The second engagement portion 73B, when it is intended to engage the first engagement portion 73A having engaging surface 73A 1 to the opening 61a side, the end portion of the opening 61a side of the two arm portions 73B 1 connected by the shaft portion 73B 2, is fixed to the inner wall surface 62c (62d) ends of the opening 61b side of the two arm portions 73B 1. In contrast, if one intends to engage the first engagement portion 73A having engaging surface 73A 1 to the opening 61b side shaft end portion of the opening 61b side of the two arm portions 73B 1 connecting in parts 73B 2, is fixed to the inner wall surface 62c (62d) ends of the opening 61a side of the two arm portions 73B 1.

側壁部７１ｃの外壁面と内壁面６２ｃとの間の２つの保持部材保持機構７３では、接続体保持部材７１が積層方向の内の一方に動こうとしたときに、一方の保持部材保持機構７３において係合面７３Ａ１が軸部７３Ｂ２で係止され、接続体保持部材７１が積層方向の内の他方に動こうとしたときに、他方の保持部材保持機構７３において係合面７３Ａ１が軸部７３Ｂ２で係止される。このような係合面７３Ａ１と軸部７３Ｂ２との間の係止状態は、側壁部７１ｄの外壁面と内壁面６２ｄとの間の２つの保持部材保持機構７３においても同様に起こっている。このため、接続体保持部材７１は、開口部６１ａ側にも開口部６１ｂ側にも抜け出ることができず、接続体収容室６１に保持される。 In the two holding member holding mechanisms 73 between the outer wall surface and the inner wall surface 62c of the side wall portion 71c, one of the holding member holding mechanisms 73 moves when the connecting member holding member 71 tries to move to one side in the stacking direction. engaging surface 73A 1 is locked by the shaft portion 73B 2 in that when the connecting member holder 71 is going to move to the other of the stacking direction, the engagement surface 73A 1 is in the other holding member holding mechanism 73 It is locked in the axial portion 73B 2. Locked state between such engagement surface 73A 1 and the shaft portion 73B 2 is going in the same manner also in the two holding member holding mechanism 73 between the outer wall surface and the inner wall surface 62d of the side wall portion 71d . For this reason, the connection body holding member 71 can not come out of the opening 61 a side nor the opening 61 b side, and is held in the connection body storage chamber 61.

ここで、保持部材保持機構７３においては、そのロック状態を解除する場合、マイナスドライバの如き治具で軸部７３Ｂ２を接続体収容室６１の内壁面６２ｃ，６２ｄ側に押し動かして、係合面７３Ａ１が軸部７３Ｂ２で係止されないようにすればよい。ここで、前述したように、保持部材保持機構７３は、開口部６１ａの近くに配置されている。このため、作業者は、保持部材保持機構７３のロック解除作業を容易に行うことができる。 Here, the holding member holding mechanism 73, the case where the locked state, the inner wall surface 62c of the connector accommodating chamber 61 to the shaft portion 73B 2 in such jig screwdriver, moving push 62d side, engaging surface 73A 1 may be so that it is not locked in the shaft portion 73B 2. Here, as described above, the holding member holding mechanism 73 is disposed near the opening 61 a. For this reason, the worker can easily perform the unlocking operation of the holding member holding mechanism 73.

接続体保持部材７１は、これら４つの保持部材保持機構７３によって、接続体収容室６１に対する他方の開口部６１ｂ側から作業用開口部（一方の開口部６１ａ）側への着脱と、作業用開口部側から他方の開口部６１ｂ側への着脱と、を行うことができる。このため、接続体保持部材７１は、開口部６１ｂ側から接続体収容室６１に挿入し、この接続体収容室６１に保持することができる。また、接続体保持部材７１は、開口部６１ｂ側から抜き出したい場合、開口部６１ｂ側で係止している軸部７３Ｂ２を押し動かして、保持部材保持機構７３のロック状態を解除することによって、開口部６１ｂ側から取り外すことができる。一方、接続体保持部材７１は、開口部６１ａ側から抜き出したい場合、開口部６１ａ側で係止している軸部７３Ｂ２を押し動かして、保持部材保持機構７３のロック状態を解除することによって、開口部６１ａ側から取り外すことができる。また、接続体保持部材７１は、開口部６１ａ側から接続体収容室６１に挿入し、この接続体収容室６１に保持することができる。このように、接続体保持部材７１は、どちらの開口部６１ａ，６１ｂからも着脱することができる。従って、この電気接続箱１は、第１接続体１０Ａのみならず、接続体保持部材７１に保持されている第２接続体１０Ｂのメンテナンス作業性にも優れている。 The connecting member holding member 71 is attached and detached from the other opening 61b side of the connecting member storage chamber 61 to the working opening (one opening 61a) by the four holding member holding mechanisms 73, and the working opening It is possible to perform attachment and detachment from the side of the part to the side of the other opening 61b. For this reason, the connection body holding member 71 can be inserted into the connection body storage chamber 61 from the opening 61 b side, and can be held in the connection body storage chamber 61. The connecting member holder 71, when want to extract from the opening 61b side, by moving down the shaft portion 73B 2 are locked at the opening 61b side to release the locked state of the holding member holding mechanism 73 , Can be removed from the opening 61b side. On the other hand, the connection member holder 71, when want to extract from the opening 61a side, by moving down the shaft portion 73B 2 which is locked by the opening 61a side to release the locked state of the holding member holding mechanism 73 , Can be removed from the opening 61a side. Further, the connection body holding member 71 can be inserted into the connection body storage chamber 61 from the opening 61 a side, and can be held in the connection body storage chamber 61. Thus, the connector holding member 71 can be attached and detached from either of the openings 61a and 61b. Therefore, the electrical connection box 1 is excellent in the maintenance workability of not only the first connection body 10A but also the second connection body 10B held by the connection body holding member 71.

ここで、側壁部７１ｃ，７１ｄの外壁面には、各々、並列配置された２つの第１係合部７３Ａを挟み込むように、接続体１０の積層方向に延在させた第１ガイド部８１を設けている（図１１及び図１２）。更に、接続体収容室６１の内壁面６２ｃ，６２ｄには、各々、並列配置された２つの第２係合部７３Ｂを挟み込むように、接続体１０の積層方向に延在させた第２ガイド部８２を設けている（図７及び図８）。第１ガイド部８１と第２ガイド部８２は、前述したように、互いに嵌合状態で相手を積層方向に案内するものである。これにより、作業者は、接続体保持部材７１の接続体収容室６１に対する着脱作業を容易に行うことができる。   Here, on the outer wall surfaces of the side wall portions 71c and 71d, the first guide portions 81 extended in the stacking direction of the connector 10 so as to sandwich the two first engagement portions 73A arranged in parallel are provided. Provided (FIGS. 11 and 12). Furthermore, a second guide portion extended in the stacking direction of the connector 10 so as to sandwich the two second engaging portions 73B arranged in parallel on the inner wall surfaces 62c and 62d of the connector chamber 61 respectively. 82 are provided (FIGS. 7 and 8). As described above, the first guide portion 81 and the second guide portion 82 guide each other in the stacking direction in a fitted state. Thus, the worker can easily carry out the attachment / detachment operation of the connection body holding member 71 with respect to the connection body storage chamber 61.

このように構成した電気接続箱１においては、図２に示すように、先ず、第１接続体１０Ａを開口部６１ｂ側から接続体収容室６１に挿入する。仮に、第１接続体１０Ａを開口部６１ａ側から挿入するとなると、作業者は、第１接続体１０Ａの長尺の電線４０を開口部６１ａ側から接続体収容室６１に挿入し、その後で第１接続体１０Ａ（電子部品２０と電子部品保持部材３０Ａとが組み付けられている本体部分）を開口部６１ａ側から接続体収容室６１に挿入することになる。しかしながら、この電気接続箱１においては、接続体保持機構７２によって第１接続体１０Ａを開口部６１ｂ側から挿入することができるので、電線４０を先に挿入するという工程が不要になる。このため、この電気接続箱１は、組付け作業性に優れたものとなる。前述したように、この電気接続箱１においては、第１接続体１０Ａの接続体収容室６１への挿入に伴い、接続体保持機構７２がロック状態となり、第１接続体１０Ａが接続体収容室６１に保持される。   In the electric connection box 1 configured as described above, as shown in FIG. 2, first, the first connection body 10A is inserted into the connection body accommodation chamber 61 from the opening 61b side. If the first connection body 10A is to be inserted from the opening 61a side, the worker inserts the long wire 40 of the first connection body 10A from the opening 61a side into the connection chamber 61, and then the first connection body 10A is inserted. 1) The connector 10A (the main body portion where the electronic component 20 and the electronic component holding member 30A are assembled) is inserted into the connector receiving chamber 61 from the opening 61a side. However, in the electric connection box 1, the first connection body 10A can be inserted from the opening 61b side by the connection body holding mechanism 72, so the process of inserting the electric wire 40 first becomes unnecessary. Therefore, the electrical connection box 1 is excellent in assembling workability. As described above, in the electric connection box 1, the connection body holding mechanism 72 is in the locked state as the first connection body 10A is inserted into the connection body storage chamber 61, and the first connection body 10A is in the connection body storage chamber. It is held at 61.

一方、この電気接続箱１においては、図２に示すように、第２接続体１０Ｂを開口部７１ｆ側から接続体保持部材７１の接続体収容室７１Ａに挿入しておく。前述したように、接続体保持部材７１においては、第２接続体１０Ｂの接続体収容室７１Ａへの挿入に伴い、接続体保持機構７４がロック状態となり、更に第１ガイド部８５の端部が係止部８７で係止される状態になっているので、第２接続体１０Ｂが接続体収容室７１Ａに保持される。   On the other hand, in the electric connection box 1, as shown in FIG. 2, the second connection body 10B is inserted into the connection body accommodating chamber 71A of the connection body holding member 71 from the opening 71f side. As described above, in the connection body holding member 71, the connection body holding mechanism 74 is in the locked state as the second connection body 10B is inserted into the connection body accommodating chamber 71A, and the end of the first guide portion 85 The second connecting body 10B is held in the connecting body accommodation chamber 71A because the second connecting body 10B is locked by the locking portion 87.

次に、この電気接続箱１においては、第２接続体１０Ｂが保持されている接続体保持部材７１を開口部６１ｂ側から接続体収容室６１に挿入する（図１６）。図１６では、説明の便宜上、仕切り壁部７１ｇの図示を省略している。接続体保持部材７１の挿入の際には、開口部６１ｂから第１接続体１０Ａの電線４０が飛び出している。尚、この例示では、第１接続体１０Ａのそれぞれの電線４０がテープ等で束ねられている（図２等）。ここで、図１５に示すように、接続体保持部材７１の凹部７１ｅと接続体収容室６１との間には、第１接続体１０Ａの電線４０を挿通させ且つ開口部６１ｂから引き出させる電線挿通路Ｐが形成される。具体的に、その電線挿通路Ｐは、接続体収容室６１の内部において、第１接続体１０Ａ側と開口部６１ｂ側とを連通させる。このため、作業者は、電線挿通路Ｐとなる接続体保持部材７１の凹部７１ｅに第１接続体１０Ａの電線４０を導きながら、接続体保持部材７１を開口部６１ｂ側から接続体収容室６１に挿入する。これにより、この電気接続箱１においては、接続体保持部材７１を組み付ける際に、第１接続体１０Ａの電線４０の噛み込みの発生を抑えることができる。前述したように、この電気接続箱１においては、接続体保持部材７１の接続体収容室６１への挿入に伴い、保持部材保持機構７３がロック状態となり、接続体保持部材７１が接続体収容室６１に保持される。従って、第２接続体１０Ｂは、その接続体保持部材７１を介して接続体収容室６１に保持される。   Next, in the electric connection box 1, the connector holding member 71 holding the second connector 10B is inserted into the connector receiving chamber 61 from the opening 61b side (FIG. 16). In FIG. 16, the illustration of the partition wall 71g is omitted for the convenience of description. At the time of insertion of the connection body holding member 71, the electric wire 40 of the first connection body 10A protrudes from the opening 61b. In addition, in this example, each electric wire 40 of 10 A of 1st connection bodies is bundled with the tape etc. (FIG. 2 etc.). Here, as shown in FIG. 15, between the recess 71e of the connection member holding member 71 and the connection member accommodation chamber 61, the wire insertion of the first connection member 10A is made to be inserted and pulled out from the opening 61b. A passage P is formed. Specifically, the wire insertion path P causes the first connecting body 10A side and the opening 61b side to communicate with each other in the inside of the connecting body accommodation chamber 61. For this reason, the worker guides the wire 40 of the first connector 10A to the recess 71e of the connector holding member 71 to be the wire insertion path P, and the connector holding chamber 71 from the opening 61b side. Insert into Thus, in the electric connection box 1, when the connector holding member 71 is assembled, the occurrence of the biting of the electric wire 40 of the first connector 10A can be suppressed. As described above, in the electric connection box 1, the holding member holding mechanism 73 is locked as the connection member holding member 71 is inserted into the connection member storage chamber 61, and the connection member holding member 71 is in the connection member storage chamber. It is held at 61. Therefore, the second connection body 10B is held in the connection body accommodating chamber 61 via the connection body holding member 71.

ここで、図示しないが、この電気接続箱１においては、開口部６１ａ側がアッパーカバーで塞がれると共に、開口部６１ｂ側がアンダーカバーで塞がれる。   Here, although not shown, in the electrical connection box 1, the opening 61a side is closed by the upper cover, and the opening 61b side is closed by the under cover.

この電気接続箱１のメンテナンス作業時には、アッパーカバーを外し、第１接続体１０Ａの電子部品２０の状態確認（ヒューズの溶断等）や交換を行うことができる。更に、メンテナンス作業時には、図１７に示すように第１接続体１０Ａを開口部６１ａ側から取り外すことで、例えば第１接続体１０Ａの電線４０の状態確認（導通等）を行うことができる。   At the time of maintenance work of the electrical connection box 1, the upper cover can be removed, and the state confirmation (fusion or the like of a fuse) or replacement of the electronic component 20 of the first connector 10A can be performed. Furthermore, at the time of maintenance work, as shown in FIG. 17, by removing the first connection body 10A from the opening 61a side, it is possible to perform, for example, state confirmation (such as conduction) of the wire 40 of the first connection body 10A.

また、この電気接続箱１においては、第１接続体１０Ａを取り外した後、図１８に示すように、第２接続体１０Ｂと共に接続体保持部材７１を開口部６１ａ側から取り外すことができる。図１８では、説明の便宜上、仕切り壁部７１ｇの図示を省略している。そして、第２接続体１０Ｂは、図１９に示すように接続体保持部材７１から取り外すことで、電子部品２０や電線４０等のメンテナンス作業を行うことができる。このように、この電気接続箱１においては、接続体収容室６１の奥深くに配置される接続体１０（第２接続体１０Ｂ）を接続体保持部材７１に保持させ、この接続体保持部材７１と一緒に接続体収容室６１に対して着脱できるようにしているので、そのような接続体１０の着脱が容易になり、延いては、この接続体１０のメンテナンス作業性を向上させることができる。   Further, in the electric connection box 1, after the first connection body 10A is removed, the connection body holding member 71 can be removed from the opening 61a side together with the second connection body 10B as shown in FIG. In FIG. 18, the illustration of the partition wall 71g is omitted for the convenience of description. Then, by removing the second connection body 10B from the connection body holding member 71 as shown in FIG. 19, the maintenance work of the electronic component 20, the electric wire 40, and the like can be performed. As described above, in the electric connection box 1, the connection body holding member 71 holds the connection body 10 (second connection body 10 B) disposed deep in the connection body storage chamber 61, and the connection body holding member 71 Since the connection body storage chamber 61 can be attached and detached together, such connection body 10 can be easily attached and detached, and the maintenance workability of the connection body 10 can be improved.

以上示したように、本実施形態の電気接続箱１は、その組付け時における作業性を向上させることができる。更に、この電気接続箱１は、車両に取り付けた後のメンテナンス作業時における作業性についても向上させることができる。また更に、この電気接続箱１は、組付け作業性やメンテナンス性に優れているので、接続体収容室６１の内部に複数の接続体１０を積層することができる。よって、この電気接続箱１は、接続体収容室６１の内部を有効活用して、多くの電子部品２０を収容することができるので、電子部品２０の収容性を向上させることができる。このように、本実施形態の電気接続箱１は、電子部品２０を含む接続体１０の良好な組付け作業性と、この接続体１０の良好なメンテナンス性と、電子部品２０の良好な収容性と、を同時に実現することができる。従って、この電気接続箱１を備えた本実施形態のワイヤハーネスＷＨについても、同様の効果を得ることができる。   As described above, the electrical connection box 1 of the present embodiment can improve the workability at the time of assembly. Furthermore, the electric connection box 1 can also improve the workability at the time of maintenance work after being attached to a vehicle. Furthermore, since the electrical connection box 1 is excellent in assembly workability and maintainability, the plurality of connection bodies 10 can be stacked inside the connection body accommodation chamber 61. Therefore, since the electrical connection box 1 can accommodate many electronic components 20 by effectively utilizing the inside of the connection body accommodation chamber 61, the accommodation of the electronic components 20 can be improved. Thus, in the electric connection box 1 of the present embodiment, good assembly workability of the connector 10 including the electronic component 20, good maintenance of the connector 10, and good accommodation of the electronic component 20 are obtained. And can be realized simultaneously. Therefore, the same effect can be acquired also about the wire harness WH of this embodiment provided with this electrical connection box 1. FIG.

一方、第１接続体収容室１７１Ａは、図２２に示すように、４つの側壁部１７１ａ，１７１ｂ，１７１ｃ，１７１ｄによって囲まれた空間である。この第１接続体収容室１７１Ａと第１接続体１０Ａとの間には、第２接続体収容室１７１Ｂと同じ接続体保持機構７４が少なくとも２箇所に設けられている。この例示では、互いに対向している電子部品保持部材３０Ａの側壁面３２ａと側壁部１７１ａの内壁面との間、互いに対向している電子部品保持部材３０Ａの側壁面３２ｃと側壁部１７１ｃの内壁面との間、及び、互いに対向している電子部品保持部材３０Ａの側壁面３２ｄと側壁部１７１ｄの内壁面との間に、接続体保持機構７４を１つずつ配置している。その側壁面３２ａ，３２ｃ，３２ｄには、各々、第１係合部７４Ａを設けると共に、第１ガイド部８５を設ける（図２３）。また、第１接続体収容室１７１Ａにおいては、側壁部１７１ａ，１７１ｃ，１７１ｄのそれぞれの内壁面に第２係合部７４Ｂを設けると共に、第２ガイド部８６及び係止部８７を設ける（図２２）。その第１係合部７４Ａにおいては、第１接続体１０Ａの第１接続体収容室１７１Ａへの挿入方向とは逆向きに係合面７４Ａ１を向けている。そして、第２係合部７４Ｂの係合面７４Ｂ１は、係合面７４Ａ１に対向させるべく、第１接続体１０Ａの第１接続体収容室１７１Ａへの挿入方向に向けている。第１接続体１０Ａは、これらの接続体保持機構７４によって、開口部１７１ｈ側からの第１接続体収容室１７１Ａに対する着脱を行うことができる。 On the other hand, as shown in FIG. 22, the first connector housing chamber 171A is a space surrounded by four side wall portions 171a, 171b, 171c, and 171d. Between the first connection body accommodation chamber 171A and the first connection body 10A, the connection body holding mechanism 74 which is the same as the second connection body accommodation chamber 171B is provided at at least two places. In this example, between the side wall surface 32a of the electronic component holding member 30A facing each other and the inner wall surface of the side wall portion 171a, the side wall surface 32c of the electronic component holding member 30A facing each other and the inner wall surface of the side wall portion 171c The connector holding mechanism 74 is disposed one by one between the side wall surface 32d of the electronic component holding member 30A facing each other and the inner wall surface of the side wall portion 171d. The side wall surfaces 32a, 32c and 32d are each provided with a first engaging portion 74A and a first guide portion 85 (FIG. 23). Further, in the first connector housing chamber 171A, the second engaging portion 74B is provided on the inner wall surface of each of the side wall portions 171a, 171c, 171d, and the second guide portion 86 and the locking portion 87 are provided (FIG. 22). ). In its first engagement portion 74A, the first insertion direction of the connection member accommodating chamber 171A of the first connection member 10A which is directed toward the engagement surface 74A 1 in the opposite direction. The engagement surface 74B 1 of the second engagement portion 74B, in order to face the engaging surface 74A 1, which is directed toward the insertion direction into the first connector housing chamber 171A of the first connection member 10A. The first connection body 10A can be attached to and detached from the first connection body accommodating chamber 171A from the opening 171h side by these connection body holding mechanisms 74.

尚、本変形例の第１接続体１０Ａは、接続体収容室６１に直接保持させず、第２接続体１０Ｂと同じように、接続体保持部材１７１を介して接続体収容室６１に保持させる。このため、本変形例の第１接続体１０Ａは、実施形態のものとは異なり、接続体保持機構７２の第１係合部７２Ａを設けていない。   The first connector 10A of this modification is not held directly in the connector housing chamber 61, but is held in the connector housing chamber 61 via the connector holding member 171 in the same manner as the second connector 10B. . Therefore, unlike the embodiment of the first connection body 10A of the present modification, the first engagement portion 72A of the connection body holding mechanism 72 is not provided.

ここで、この接続体保持部材１７１においては、第１接続体収容室１７１Ａと第２接続体収容室１７１Ｂとの間に、仕切り壁部１７１ｇが設けられている（図２０）。また、第２接続体収容室１７１Ｂ側の側壁部１７１ｂと側壁部１７１ｃとの間には、接続体保持部材７１と同じように、接続体収容室６１との間で電線挿通路Ｐを成す凹部１７１ｅが形成されている。一方、この接続体保持部材１７１では、第１接続体収容室１７１Ａ側の側壁部１７１ｂと側壁部１７１ｃとの間に切欠き１７１ｉを設けている（図２０）。その切欠き１７１ｉは、第１接続体１０Ａの電線４０を第１接続体収容室１７１Ａの外に引き出す部位であると共に、その電線４０を凹部１７１ｅに導くものでもある。   Here, in the connection body holding member 171, a partition wall 171g is provided between the first connection body accommodation chamber 171A and the second connection body accommodation chamber 171B (FIG. 20). Further, between the side wall portion 171b and the side wall portion 171c on the side of the second connection body storage chamber 171B, similarly to the connection body holding member 71, a recess that forms a wire insertion path P with the connection body storage chamber 61. 171e is formed. On the other hand, in the connection body holding member 171, a notch 171i is provided between the side wall portion 171b and the side wall portion 171c on the side of the first connection body accommodation chamber 171A (FIG. 20). The notch 171i is a portion for drawing the wire 40 of the first connection body 10A to the outside of the first connection body accommodating chamber 171A, and also leads the wire 40 to the recess 171e.

接続体保持部材１７１と接続体収容室６１との間には、実施形態と同じように、保持部材保持機構７３を設ける。この例示では、互いに対向している側壁部１７１ａの外壁面と内壁面６２ａとの間、及び、互いに対向している側壁部１７１ｂの外壁面と内壁面６２ｂとの間に、保持部材保持機構７３を２つずつ設けると共に、第１及び第２のガイド部８１，８２を設ける（図２１、図２２、図２４）。側壁部１７１ａ，１７１ｂのそれぞれの外壁面には、２つの第１係合部７３Ａが、接続体１０の積層方向に対する直交方向に並列配置される。その並列配置された２つの第１係合部７３Ａにおいては、一方の第１係合部７３Ａの係合面７３Ａ１が積層方向における一方側（開口部６１ａ側）に配置され、他方の第１係合部７３Ａの係合面７３Ａ１が積層方向における他方側（開口部６１ｂ側）に配置される。第２係合部７３Ｂは、軸部７３Ｂ２で係合面７３Ａ１を係止できるように、その４つの第１係合部７３Ａと各々対向する内壁面６２ａ，６２ｂの所定位置に配置する。このため、接続体保持部材１７１は、実施形態の接続体保持部材７１と同じように、開口部６１ａ側にも開口部６１ｂ側にも抜け出ることができず、接続体収容室６１に保持される。また、この接続体保持部材１７１は、これら４つの保持部材保持機構７３によって、実施形態の接続体保持部材７１と同じように、接続体収容室６１に対する他方の開口部６１ｂ側から作業用開口部（一方の開口部６１ａ）側への着脱と、作業用開口部側から他方の開口部６１ｂ側への着脱と、を行うことができる。 A holding member holding mechanism 73 is provided between the connection member holding member 171 and the connection member accommodation chamber 61 as in the embodiment. In this example, a holding member holding mechanism 73 is provided between the outer wall surface and the inner wall surface 62a of the side wall portion 171a facing each other, and between the outer wall surface and the inner wall surface 62b of the side wall portion 171b facing each other. Are provided two by one, and the first and second guide portions 81 and 82 are provided (FIG. 21, FIG. 22, FIG. 24). The two first engaging portions 73A are arranged in parallel in the direction orthogonal to the stacking direction of the connection body 10 on the outer wall surfaces of the side wall portions 171a and 171b. In the two first engaging portions 73A arranged in parallel, the engaging surface 73A1 of one first engaging portion 73A is disposed on one side (opening 61a side) in the stacking direction, and the other first engaging surface 73A 1 of the engaging portion 73A is disposed on the other side in the stacking direction (the opening portion 61b side). The second engagement portion 73B, as can lock the engagement surface 73A 1 at the shaft portion 73B 2, the four first engagement portion 73A and the respective opposing inner wall surface 62a, arranged at a predetermined position of 62b. For this reason, the connection body holding member 171 can not be pulled out to the opening 61a side or the opening 61b side as in the connection body holding member 71 of the embodiment, and is held in the connection body storage chamber 61. . Further, the connecting member holding member 171 is a working opening from the other opening 61 b side with respect to the connecting member accommodation chamber 61 by the four holding member holding mechanisms 73 in the same manner as the connecting member holding member 71 of the embodiment. Attachment and detachment to the (one opening 61a) side and attachment and detachment to the other opening 61b side from the operation opening can be performed.

本変形例では、先ず、図２０に示すように第１接続体１０Ａと第２接続体１０Ｂを接続体保持部材１７１の第１接続体収容室１７１Ａと第２接続体収容室１７１Ｂに収容し、これらを接続体保持機構７４によって一体化させる（図２５）。その際、第１接続体１０Ａは、切欠き１７１ｉを介して電線４０を凹部１７１ｅに導きながら、開口部１７１ｈから挿入していく。   In this modification, first, as shown in FIG. 20, the first connection body 10A and the second connection body 10B are accommodated in the first connection body accommodation chamber 171A and the second connection body accommodation chamber 171B of the connection body holding member 171, These are integrated by the connector holding mechanism 74 (FIG. 25). At this time, the first connector 10A inserts the wire 40 from the opening 171 h while guiding the wire 40 to the recess 171 e through the notch 171 i.

ところで、図２６には、筐体６０の具体例を示している。本図の符号６０Ａは、接続体収容室６１が形成されるフレームを示している。この種の筐体６０は、そのフレーム６０Ａの一方の開口（開口部６１ａ側）がアッパーカバー（図示略）で塞がれると共に、開口部６１ｂ側がアンダーカバー（図示略）で塞がれる。フレーム６０Ａには、接続体保持部材１７１だけでなく、例えば単体の電子部品２０等も取り付けられる。   Incidentally, FIG. 26 shows a specific example of the case 60. Reference numeral 60A in the drawing indicates a frame in which the connection body accommodation chamber 61 is formed. In the case 60 of this type, one opening (the opening 61a side) of the frame 60A is closed by an upper cover (not shown) and the opening 61b side is closed by an under cover (not shown). Not only the connection member holding member 171 but also, for example, a single electronic component 20 or the like is attached to the frame 60A.

次に、この電気接続箱２においては、その第１接続体１０Ａと第２接続体１０Ｂと接続体保持部材１７１の一体化物を開口部６１ｂ側から接続体収容室６１に挿入する（図２６）。その挿入に際して、接続体収容室６１には、他の接続体１０等の他部品が挿入されていない。そして、その一体化物の挿入時には、第１接続体１０Ａの電線４０が凹部１７１ｅに沿わされている。このため、この電気接続箱２においては、第１接続体１０Ａが接続体収容室６１に先に挿入されている実施形態の電気接続箱１と比べて、組付け作業時における第１接続体１０Ａの電線４０の噛み込みをより抑えることができる。   Next, in the electric connection box 2, the integrated body of the first connector 10A, the second connector 10B and the connector holding member 171 is inserted into the connector accommodating chamber 61 from the opening 61b side (FIG. 26) . At the time of the insertion, other components such as the other connection body 10 are not inserted into the connection body storage chamber 61. And at the time of the insertion of the integrated thing, the electric wire 40 of 10 A of 1st connection bodies is along the recessed part 171e. For this reason, in the electric connection box 2, compared with the electric connection box 1 of the embodiment in which the first connection body 10A is inserted into the connection body storage chamber 61 first, the first connection body 10A at the time of assembly work The bite of the electric wire 40 can be further suppressed.

この電気接続箱２においては、その一体化物の挿入に伴い、保持部材保持機構７３がロック状態となり、接続体保持部材１７１が接続体収容室６１に保持される。従って、この電気接続箱２では、全ての接続体１０（第１接続体１０Ａと第２接続体１０Ｂ）が接続体保持部材１７１を介して接続体収容室６１に保持される。   In the electric connection box 2, the holding member holding mechanism 73 is locked with the insertion of the integrated body, and the connection body holding member 171 is held in the connection body accommodation chamber 61. Therefore, in the electrical connection box 2, all the connectors 10 (the first connectors 10 A and the second connectors 10 B) are held in the connector storage chamber 61 via the connector holding member 171.

この電気接続箱２のメンテナンス作業時には、アッパーカバーを外し、第１接続体１０Ａの電子部品２０の状態確認（ヒューズの溶断等）や交換を行うことができる。更に、メンテナンス作業時には、図２７に示すように接続体保持部材１７１を開口部６１ａ側から取り外すだけで、全ての接続体１０（第１接続体１０Ａと第２接続体１０Ｂ）を接続体収容室６１から取り出すことができる。そして、この電気接続箱２においては、接続体保持部材１７１からメンテナンス対象又は全ての接続体１０を取り外すことで、取り外した接続体１０のメンテナンス作業を行うことができる。従って、この電気接続箱２は、何れの階層に配置された接続体１０であっても、メンテナンス作業を容易に行うことができる。よって、この電気接続箱２は、接続体１０の更なる多段化を図ることができるので、更に収容性を向上させることができる。   At the time of maintenance work of the electric connection box 2, the upper cover can be removed, and state confirmation (fusion of fuse, etc.) or replacement of the electronic component 20 of the first connector 10 A can be performed. Furthermore, at the time of maintenance work, as shown in FIG. 27, all the connectors 10 (the first connectors 10A and the second connectors 10B) can be connected to the connector housing chamber simply by removing the connector holding member 171 from the opening 61a side. It can be taken out from 61. Then, in the electric connection box 2, the maintenance work of the removed connection body 10 can be performed by removing the maintenance object or all the connection bodies 10 from the connection body holding member 171. Therefore, the electrical connection box 2 can easily perform the maintenance operation, regardless of the connection body 10 disposed in any layer. Therefore, since this electrical connection box 2 can achieve further multistage formation of the connection body 10, accommodation property can be further improved.

以上示したように、本変形例の電気接続箱２は、実施形態の電気接続箱１と同様の効果が得られるだけでなく、その電気接続箱１に対して、電子部品２０を含む接続体１０の組付け作業性と、この接続体１０のメンテナンス性と、電子部品２０の収容性と、を更に向上させることができる。よって、この電気接続箱２を備えた本変形例のワイヤハーネスＷＨについても、同様の効果を得ることができる。   As described above, the electrical connection box 2 of this modification not only provides the same effects as the electrical connection box 1 of the embodiment, but also a connection body including the electronic component 20 with respect to the electrical connection box 1 It is possible to further improve the assembling workability of 10, the maintainability of the connector 10, and the accommodation of the electronic component 20. Therefore, the same effect can be acquired also about the wire harness WH of this modification provided with this electrical connection box 2. FIG.

ここで、本変形例では、実施形態の電気接続箱１において、作業用開口部に最も近い接続体１０（第１接続体１０Ａ）と接続体保持部材７１との間に接続体保持機構７４を少なくとも２箇所に追加することで、全ての接続体１０を接続体保持部材７１に保持させてもよい。ここで、この場合には、接続体収容室６１と接続体保持部材７１との間の保持部材保持機構７３を残してもよく、また、この保持部材保持機構７３を全て廃止してもよい。このように構成したとしても、上記の電気接続箱２と同様の効果を得ることができる。更に、この場合には、接続体１０の積層化が必要無いときに、上層の第１接続体１０Ａのみを接続体収容室６１に収容することができるので、筐体６０を変えることなく、電気接続箱のバリエーションの拡張を図ることができる。   Here, in the present modification, in the electric connection box 1 of the embodiment, the connection body holding mechanism 74 is disposed between the connection body 10 (first connection body 10A) closest to the work opening and the connection body holding member 71. All the connectors 10 may be held by the connector holding member 71 by being added to at least two places. Here, in this case, the holding member holding mechanism 73 may be left between the connection body storage chamber 61 and the connection body holding member 71, or all of the holding member holding mechanism 73 may be eliminated. Even if configured in this manner, the same effect as the above electrical connection box 2 can be obtained. Furthermore, in this case, only the first connection body 10A in the upper layer can be accommodated in the connection body accommodation chamber 61 when stacking of the connection body 10 is not necessary. Variations of connection boxes can be expanded.
