まず、作業者は、配索材７をフレーム本体３の下方側から収容空間部２ａに挿入し、フレーム本体３に固定させる。次に、作業者は、フレーム本体３の上方側から開口部を介してフレーム本体３に電子部品１００を組み付けて、電子部品１００と複数の配索材７Ａ，７Ｂとを電気的に接続する。次に、作業者は、ロアカバー５をフレーム本体３の下方側に位置させ、複数の配索材７Ａ，７Ｂを、各挿通孔１３，１４に挿通させる。このとき、作業者は、配索材７Ｂを載置面２１に向けて載置面２３を沿わせ、一対の突起部２７よりも上方側に押し込むようにして、配索材７Ｂを載置面２１に載置する（図５、図６）。次に、作業者は、配索材７Ａを、対向する２つの載置面２３の間に押し込むように載置する（図７）。次に、作業者は、配索材７Ａを載置面３１に載置すると共に、配索材７Ｂを載置面３３に載置する（図１０）。 First, the operator inserts the wiring member 7 into the accommodation space 2a from the lower side of the frame body 3 and fixes it to the frame body 3 . Next, the operator assembles the electronic component 100 to the frame body 3 from the upper side of the frame body 3 through the opening, and electrically connects the electronic component 100 and the wiring members 7A and 7B. Next, the operator positions the lower cover 5 on the lower side of the frame main body 3 and inserts the plurality of wiring members 7A and 7B into the insertion holes 13 and 14, respectively. At this time, the operator directs the wiring member 7B toward the mounting surface 21 so that the mounting surface 23 is along the mounting surface 23, and pushes the wiring member 7B upward beyond the pair of projections 27, thereby moving the wiring member 7B onto the mounting surface. 21 (FIGS. 5 and 6). Next, the operator places the wiring material 7A so as to be pushed between the two opposing placement surfaces 23 (FIG. 7). Next, the operator places the wiring member 7A on the mounting surface 31 and the wiring member 7B on the mounting surface 33 (FIG. 10).

次に、作業者は、挿通孔１３，１４から延出する配索材７Ａ，７Ｂを、固定部２５，３５の内周面に沿わせて、結束部材４１により固定部２５，３５と共に結束してフレーム本体３側に固定する。次に、作業者は、ロアカバー５をフレーム本体３の下方側から挿入し、フレーム本体３に対してロアカバー５を係止機構により係止する。次に、作業者は、アッパーカバー４をフレーム本体３の上方側に位置させ、アッパーカバー４とフレーム本体３の開口部とが対向するようにして、アッパーカバー４をフレーム本体３の上側に組み付けて係止機構により係止する。以上により、電気接続箱１の組み立てが完了する。 Next, the worker binds the wiring members 7A and 7B extending from the insertion holes 13 and 14 along the inner peripheral surfaces of the fixed portions 25 and 35 together with the fixed portions 25 and 35 with the binding member 41. and fix it to the frame main body 3 side. Next, the operator inserts the lower cover 5 from the lower side of the frame body 3 and locks the lower cover 5 to the frame body 3 by the locking mechanism. Next, the operator positions the upper cover 4 on the upper side of the frame body 3 and assembles the upper cover 4 on the upper side of the frame body 3 so that the upper cover 4 and the opening of the frame body 3 face each other. is locked by the locking mechanism. As described above, the assembly of the electric junction box 1 is completed.

以上のように、本実施形態に係る電気接続箱１は、１以上の電子部品１００を収容する筐体２と、筐体２の側壁１５に形成され、かつ電子部品１００に電気的に接続される２以上の配索材７が挿通される挿通孔１３と、挿通孔１３の一部を構成する載置面２１とを備える。配索材７は、特定の配索材７Ａまたは７Ｂが含まれる。載置面２１は、配索材７Ａまたは７Ｂが挿通孔１３に挿通された挿通状態において、配索材７Ａまたは７Ｂの延在方向に延在し、かつ配索材７Ａまたは７Ｂの外周面の一部に沿って形成される。 As described above, the electrical connection box 1 according to the present embodiment includes a housing 2 that houses one or more electronic components 100, and a side wall 15 of the housing 2 that is electrically connected to the electronic components 100. and a mounting surface 21 forming a part of the insertion hole 13 . The wiring material 7 includes a specific wiring material 7A or 7B. The mounting surface 21 extends in the direction in which the wiring member 7A or 7B extends in the insertion state in which the wiring member 7A or 7B is inserted through the insertion hole 13, and extends along the outer peripheral surface of the wiring member 7A or 7B. Formed along a section.

上記構成により、例えば、外径が異なる複数の配索材７を挿通孔１３に挿通させて電気接続箱１を組み立てる際に、外径が最も小さい配索材７Ｂを挿通孔１３の載置面２１に載置することで当該配索材７Ｂが筐体２側に一時的に保持される。さらに、外径が最も大きい配索材７Ａを、対向する２つの載置面２３で挟み込むように載置することで当該配索材７Ａが筐体２側に一時的に保持される。この結果、結束部材４１により複数の配索材７を筐体２側に固定するまでの間、挿通孔１３を通した配索材７の位置ずれを容易に抑制することができる。また、外径が最も大きい配索材７Ａを、挿通孔１４の載置面３１ではなく載置面３３に載置しても、太さが合わないことを作業者がすぐに気づくことができ、組付け作業の精度をあげることができる。 With the above configuration, for example, when assembling the electrical junction box 1 by inserting a plurality of wiring members 7 having different outer diameters through the insertion holes 13, the wiring members 7B having the smallest outer diameter are placed on the mounting surfaces of the insertion holes 13. 21, the wiring member 7B is temporarily held on the housing 2 side. Furthermore, by placing the wiring member 7A having the largest outer diameter so as to be sandwiched between the two facing mounting surfaces 23, the wiring member 7A is temporarily held on the housing 2 side. As a result, until the plurality of wiring members 7 are fixed to the housing 2 side by the binding member 41 , it is possible to easily suppress positional displacement of the wiring members 7 through the insertion holes 13 . Also, even if the wiring member 7A having the largest outer diameter is placed on the placement surface 33 of the insertion hole 14 instead of the placement surface 31, the operator can immediately notice that the thickness does not match. , the accuracy of assembly work can be increased.

また、本実施形態に係る電気接続箱１は、挿通孔１３の一部を構成し、かつ載置面２１と異なる載置面２３を備える。載置面２１は、配索材７の挿通方向から視てＵ字状に形成されており、両端に対向して形成され、かつ内側に向けて突出する一対の突起部２７を有する。載置面２３は、載置面２１の両端の少なくとも一方と連続して形成され、上記挿通状態において、配索材７Ｂの延在方向に延在し、かつ配索材７Ｂの外周面の一部が載置される。このように、載置面２１がＵ字状に形成されるので、当該載置面２１と配索材７の外周面との接触面積を増やして、挿通孔１３に挿通された配索材７の位置ずれを抑制することができる。また、載置面２１の両端に対向して形成された一対の突起部２７により、載置面２１に載置された配索材７の挿通孔１３から下方向への移動を規制することができ、配索材７の位置ずれを抑制することができる。また、載置面２３が載置面２１の両端の一方または両方に連続して形成されるので、載置面２１に載置された複数の配索材７をまとめて結束しやすくなる。 Moreover, the electric connection box 1 according to the present embodiment includes a mounting surface 23 that constitutes a part of the insertion hole 13 and is different from the mounting surface 21 . The mounting surface 21 is formed in a U shape when viewed from the insertion direction of the wiring member 7, and has a pair of projecting portions 27 formed facing each other at both ends and protruding inward. The mounting surface 23 is formed continuously with at least one of both ends of the mounting surface 21, extends in the extending direction of the wiring member 7B, and extends on one side of the outer peripheral surface of the wiring member 7B in the inserted state. part is placed. Thus, since the mounting surface 21 is formed in a U-shape, the contact area between the mounting surface 21 and the outer peripheral surface of the wiring member 7 is increased, and the wiring member 7 inserted through the insertion hole 13 is removed. can be suppressed. A pair of protrusions 27 formed on opposite ends of the mounting surface 21 can restrict the downward movement of the wiring member 7 placed on the mounting surface 21 from the insertion hole 13 . It is possible to suppress positional deviation of the wiring material 7 . In addition, since the mounting surface 23 is formed continuously on one or both of both ends of the mounting surface 21, the plurality of wiring members 7 mounted on the mounting surface 21 can be easily bundled together.

また、本実施形態に係る電気接続箱１は、挿通孔１４の一部を構成し、かつ載置面３１と異なる載置面３３を備える。載置面３３は、載置面３１の両端の一方と連続して形成され、配索材７の延在方向に延在し、かつ配索材７の外周面の一部が載置される。載置面３１と載置面３３とは、隣り合うように連続して形成される。このように、載置面２３が載置面２１の両端の一方に連続して形成され、載置面３１と載置面３３とは、隣り合うように連続して形成されるので、外径が異なる複数の配索材７が筐体２側に組付けやすくなる共に、複数の配索材７Ａ，７Ｂの位置ずれを抑制することができる。 Moreover, the electric connection box 1 according to the present embodiment includes a mounting surface 33 that constitutes a part of the insertion hole 14 and is different from the mounting surface 31 . The mounting surface 33 is formed continuously with one of both ends of the mounting surface 31, extends in the extending direction of the wiring member 7, and has a part of the outer peripheral surface of the wiring member 7 mounted thereon. . The mounting surface 31 and the mounting surface 33 are continuously formed so as to be adjacent to each other. In this manner, the mounting surface 23 is formed continuously on one of both ends of the mounting surface 21, and the mounting surfaces 31 and 33 are formed continuously so as to be adjacent to each other. It is possible to easily assemble the plurality of wiring members 7 having different thicknesses to the side of the housing 2, and to suppress the positional deviation of the plurality of wiring members 7A and 7B.

また、本実施形態に係る電気接続箱１は、筐体２の側壁１５に形成され、かつ配索材７の延在方向に沿って側壁１５から外側に向けて突出する固定部２５，３５と、複数の配索材７を結束する結束部材４１とを備える。結束部材４１は、配索材７Ａおよび配索材７Ｂが載置面２１，３１および載置面２３，３３に載置された載置状態において、配索材７Ａおよび配索材７Ｂを固定部２５，３５と共に結束する。このように、各載置面に配索材が載置された状態で結束部材４１により結束できるように固定部２５，３５が筐体２の側壁１５に形成されているので、筐体２に対する複数の配索材７の固定を容易に行うことができる。 In addition, the electric connection box 1 according to the present embodiment includes fixing portions 25 and 35 formed on the side wall 15 of the housing 2 and protruding outward from the side wall 15 along the extending direction of the wiring member 7. , and a binding member 41 for binding the plurality of wiring members 7 . The binding member 41 fixes the wiring material 7A and the wiring material 7B to the mounting surfaces 21 and 31 and the mounting surfaces 23 and 33 in a mounted state in which the wiring material 7A and the wiring material 7B are mounted. Bundle together with 25,35. As described above, the fixing portions 25 and 35 are formed on the side wall 15 of the housing 2 so that the wiring members placed on the respective mounting surfaces can be bound by the binding member 41. A plurality of wiring members 7 can be easily fixed.

また、本実施形態に係るワイヤハーネスＷＨは、配索材７と、電気接続箱１とを備える。配索材７は、２以上の配索材７Ａ，７Ｂのうち、外径が最も大きい配索材７が含まれる。載置面２１，３１は、上記挿通状態において、配索材７の延在方向に延在し、かつ配索材７の外周面の一部に沿って形成される。上記構成により、上述した電気接続箱１と同様に、組立作業時において、挿通孔を通した電線束の位置ズレを抑制することができる、という効果を奏する。 Moreover, the wire harness WH according to the present embodiment includes the wiring member 7 and the electric connection box 1 . The wiring member 7 includes the wiring member 7 having the largest outer diameter among the two or more wiring members 7A and 7B. The placement surfaces 21 and 31 extend in the extending direction of the wiring member 7 and are formed along a part of the outer peripheral surface of the wiring member 7 in the inserted state. With the above configuration, as with the electric connection box 1 described above, it is possible to suppress positional displacement of the wire bundle passed through the insertion hole during assembly work.

なお、上記実施形態では、載置面２３に載置される配索材７Ａが、外径が最も大きい第１配索材とし、載置面２１に載置される配索材７Ｂが、第１配索材より外径が小さい第２配索材としているが、これに限定されず、逆であってもよい。すなわち、載置面２１に載置される配索材７Ａが、外径が最も大きい第１配索材とし、載置面２３に載置される配索材７Ｂが、第１配索材より外径が小さい第２配索材としてもよい。このように、電気接続箱１は、配索材７が、２以上の配索材７Ａ，７Ｂのうち、外径が最も大きい配索材７Ａを含むものである。載置面２１は、配索材７Ａが挿通孔１３に挿通された挿通状態において、配索材７Ａの延在方向に延在し、かつ配索材７Ａの外周面の一部に沿って形成される。これにより、例えば、外径が異なる複数の配索材７を挿通孔１３に挿通させて電気接続箱１を組み立てる際に、外径が最も最も大きい配索材７Ａを挿通孔１３の載置面２１に載置することで当該配索材７Ａが筐体２側に一時的に保持される。そして、外径が最も小さい配索材７Ｂが、対向する２つの載置面２３のいずれか一方と配索材７Ａとで筐体２側に一時的に保持される。この結果、結束部材４１により複数の配索材７を筐体２側に固定するまでの間、挿通孔１３を通した配索材７の位置ずれを容易に抑制することができる。 In the above-described embodiment, the wiring material 7A placed on the mounting surface 23 is the first wiring material having the largest outer diameter, and the wiring material 7B mounted on the mounting surface 21 is the first wiring material. Although the second wiring member has an outer diameter smaller than that of the first wiring member, the second wiring member is not limited to this and may be reversed. That is, the wiring member 7A placed on the mounting surface 21 is the first wiring member having the largest outer diameter, and the wiring member 7B mounted on the mounting surface 23 is the first wiring member. It is good also as a 2nd wiring material with a small outer diameter. In this manner, the electrical connection box 1 includes the wiring member 7A having the largest outer diameter among the two or more wiring members 7A and 7B. The placing surface 21 extends in the extending direction of the wiring member 7A and is formed along a part of the outer peripheral surface of the wiring member 7A in the insertion state in which the wiring member 7A is inserted through the insertion hole 13. be done. As a result, for example, when assembling the electric connection box 1 by inserting a plurality of wiring members 7 having different outer diameters through the insertion holes 13, the wiring member 7A having the largest outer diameter is placed on the mounting surface of the insertion hole 13. 21, the wiring member 7A is temporarily held on the housing 2 side. Then, the wiring member 7B having the smallest outer diameter is temporarily held on the side of the housing 2 by either one of the two facing mounting surfaces 23 and the wiring member 7A. As a result, until the plurality of wiring members 7 are fixed to the housing 2 side by the binding member 41 , it is possible to easily suppress positional displacement of the wiring members 7 through the insertion holes 13 .

また、上記実施形態では、載置面３１に載置される配索材７Ａが、外径が最も大きい第１配索材とし、載置面３３に載置される配索材７Ｂが、第１配索材より外径が小さい第２配索材としているが、これに限定されず、逆であってもよい。すなわち、載置面３３に載置される配索材７Ｂが、外径が最も大きい第１配索材とし、載置面３１に載置される配索材７Ａが、第１配索材より外径が小さい第２配索材としてもよい。 Further, in the above-described embodiment, the wiring material 7A placed on the mounting surface 31 is the first wiring material having the largest outer diameter, and the wiring material 7B mounted on the mounting surface 33 is the first wiring material. Although the second wiring member has an outer diameter smaller than that of the first wiring member, the second wiring member is not limited to this and may be reversed.
