2. Description of the Related Art Conventionally, as an electric connection box mounted on an automobile, Japanese Patent Application Laid-Open No. 2004-215418 (Patent Document 1) provides an electric connection box including a relay box shown in FIG. In the relay box 1, an electrical component 5 such as a relay is fitted on the upper surface of the main body case 2, and the upper cover 3 is covered on the upper surface of the main body case 2 in order to prevent the electrical component 5 from getting wet. Yes. Therefore, the wire harness connected to the electrical component 5 is drawn from the lower surface side of the main body case 2, is directed upward in the case main body 2, and is connected to the lower portion of the electrical component 5.
A wire lead-in port 6 is provided on the side surface of the lower cover 4 that covers the lower surface side of the main body case 2, and the wire harness is drawn into the box from the wire lead-in port 6. The wire lead-in port 6 also has a function as a drain port when the relay box 1 is submerged.

このような電気接続箱にワイヤハーネスが引き込まれる場合、従来、図6(A)(B)に示すようなワイヤハーネスカバー7がロアカバーに取り付けられる場合が多い。
該ワイヤハーネスカバー7には、上向き姿勢にしたワイヤハーネスW/Hを予めテープ9で巻き付け固定しておき、該ワイヤハーネスカバー7を電気接続箱の電線引き込み口に嵌合係止している。これにより、ワイヤハーネスW/Hを上向き姿勢で電気接続箱に容易に組み付けている。
When a wire harness is drawn into such an electrical junction box, conventionally, a wire harness cover 7 as shown in FIGS. 6A and 6B is often attached to the lower cover.
A wire harness W / H in an upward posture is wound around and fixed to the wire harness cover 7 with a tape 9 in advance, and the wire harness cover 7 is fitted and locked to an electric wire drawing port of an electric connection box. Thereby, the wire harness W / H is easily assembled to the electrical junction box in an upward posture.

また、ワイヤハーネスW/Hは常に電気接続箱の下方や側面側から配索されるとは限らず、上方から配索される場合もある。その場合、上方から配索される下向き姿勢のワイヤハーネスW/Hを曲げて上向き姿勢に変えることになる。この場合、前記ワイヤハーネスカバー7を用いると、前記テープ巻き代の長さだけワイヤハーネスW/Hを余分に下方へ下げてから上向きに変えることになり、ワイヤハーネスW/Hの電線長が長くなると共に、ワイヤハーネスW/Hの配索スペースを余分に必要とする点にも問題がある。   Moreover, the wire harness W / H is not always routed from the lower side or the side of the electrical junction box, and may be routed from above. In that case, the wire harness W / H in the downward posture routed from above is bent and changed to the upward posture. In this case, when the wire harness cover 7 is used, the wire harness W / H is lowered downward by the length of the tape winding allowance and then changed upward, so that the wire length of the wire harness W / H is long. In addition, there is a problem in that an extra wiring space for the wire harness W / H is required.

さらに、前記ワイヤハーネスカバー7を用いると、図6(B)に示すように、上方から配索される下向き姿勢のワイヤハーネスW/Hを固定できないため、組み付け作業性が悪いうえ、ワイヤハーネスW/Hの下回り部分が広がる、振れる、あるいは、バラける等して、他の部品に干渉しやすい点にも問題がある。   Further, when the wire harness cover 7 is used, as shown in FIG. 6B, the wire harness W / H in a downward posture routed from above cannot be fixed, so that the assembly workability is poor and the wire harness W There is also a problem in that the lower part of / H is likely to interfere with other parts by spreading, swinging, or breaking.

前記課題を解決するために、本発明は、上方から配索されてくるワイヤハーネスを下回りさせた後に上向き姿勢で引き込む構成の自動車用の電気接続箱であって、
前記電気接続箱の本体ケースあるいは該本体ケースに結合されるロアカバーの側壁の一部に、ワイヤハーネス用の下回り引込部材を設け、
前記下回り引込部材は、ワイヤハーネスの下回り距離を確保する寸法を隔てた仕切壁と外側壁を備え
前記仕切壁が前記本体ケースまたはロアカバーの側壁の一部を構成するように設けられ、前記外側壁は前記ワイヤハーネスに取り付けられたクリップを外側から挿入係止させるクリップ係止穴を設けたハーネス固定部とし、かつ、前記仕切壁より内側には、ワイヤハーネスを内部に挿通して保持し、上方へとガイドするハーネスガイド部を設け、
前記外側壁で係止したワイヤハーネスを外側壁と仕切壁の下端外方で下回りさせて前記ハーネスガイド部内に上向きに挿通させて、本体ケース内部にワイヤハーネスを上向きに引き込む構成としていることを特徴とする自動車用の電気接続箱を提供している。
In order to solve the above-mentioned problem, the present invention is an electrical connection box for an automobile having a configuration in which the wire harness routed from above is lowered and then pulled in an upward posture,
In a part of the side wall of the lower cover coupled to the main body case of the electrical junction box or the main body case, a lower retracting member for the wire harness is provided,
The lower retracting member includes a partition wall and an outer wall separated by a dimension that secures a lower distance of the wire harness ,
Harness fixing in which the partition wall is provided so as to constitute a part of the side wall of the main body case or the lower cover, and the outer wall is provided with a clip locking hole for inserting and locking a clip attached to the wire harness from the outside. and parts, and wherein the inner side of the partition wall, and held by inserting the wire harness therein, setting the harness guide portion for guiding the upward direction,
The wire harness locked by the outer wall is lowered below the outer wall and the lower end of the partition wall and inserted upward into the harness guide part, and the wire harness is pulled upward into the main body case. An electrical junction box for automobiles is provided.

前記構成により、上方から配索される部分のワイヤハーネスは、下回り引込部材の外側壁に近接する位置でクリップで係止固定され、下回りした後に電気接続箱内に引き込まれる部分のワイヤハーネスは、下回り引込部材のハーネスガイド部により仕切壁に極めて近接する位置に挿通される。従って、ワイヤハーネスの下回り部分の広がりを抑制でき、下回り部分を介した内外両側のワイヤハーネスを可能な限り近接させて配索できるため、車両内のワイヤハーネス配索スペースの省スペース化および電気接続箱の小型化を図ることができる。   With the above configuration, the portion of the wire harness that is routed from above is locked and fixed with a clip at a position close to the outer wall of the lower pull-in member, and the portion of the wire harness that is pulled into the electrical junction box after being lowered is The harness guide part of the lower retracting member is inserted into a position very close to the partition wall. Therefore, the spread of the lower part of the wire harness can be suppressed, and the wiring harnesses on both the inner and outer sides can be routed as close as possible via the lower part, thus reducing the space for wiring harness in the vehicle and making electrical connection The size of the box can be reduced.

また、前記下回り引込部材とワイヤハーネスとの固定にテープ巻きを用いないため、ワイヤハーネスの下回り下端位置は、テープ巻き代を要していた従来よりも上方位置に設定することができ、必要以上にワイヤハーネスを下方へ下げることなく下回りさせることができる。従って、ワイヤハーネス長さを最短化でき、無駄なコストをも低減できる。   In addition, since tape winding is not used for fixing the lower wire retracting member and the wire harness, the lower lower end position of the wire harness can be set to an upper position than the conventional one that required a tape winding allowance. The wire harness can be lowered without lowering. Therefore, the length of the wire harness can be minimized, and wasteful costs can be reduced.

さらに、ワイヤハーネスを電気接続箱へ組み付ける作業において、上方から取り回されるワイヤハーネスは、前記下回り引込部材の外側壁にクランプで係止固定されるため、ワイヤハーネスに癖付け等がある場合でも、常に一定の位置に正確に配索でき、作業性が向上する。

前記構成の電気接続箱10は、前記下回り引込部材20を用いることにより、上方から配索されるワイヤハーネス40の外側配索部40aと、下回りした後に上向き姿勢となって配索される内側配索部40bとを、一定位置に一定間隔で固定することができる。従って、下回りさせることによって、従来であれば広がりやすかった外側配索部40aと内側配索部40bの間隔を可能な限り縮めることができ、車両内のワイヤハーネス配索スペースを削減できると共に、電気接続箱の小型化も可能となる。   The electrical connection box 10 having the above-described configuration uses the lower lead-in member 20, and the inner wiring portion 40a of the wire harness 40 routed from above and the inner wiring routed in an upward posture after being lowered. The rope portion 40b can be fixed at a fixed position at a fixed interval. Therefore, the distance between the outer wiring portion 40a and the inner wiring portion 40b, which has conventionally been easy to spread, can be reduced as much as possible by reducing the distance, and the wiring harness wiring space in the vehicle can be reduced. The connection box can be downsized.

また、下回り引込部材20とワイヤハーネス40とを従来のようにテープ巻き固定しないため、テープ巻き代を確保するためにワイヤハーネス40を余分に下方へ下げる必要がなく、ワイヤハーネス40の長さを最短化できる。   Further, since the lower retracting member 20 and the wire harness 40 are not fixed by tape winding as in the prior art, it is not necessary to lower the wire harness 40 downward to secure the tape winding allowance, and the length of the wire harness 40 is reduced. It can be minimized.

さらに、ワイヤハーネス40の組み付け作業において、外側配索部40aをまず下回り引込部材20に固定することができるため、癖付け等のあるワイヤハーネス40でも正確な形状および位置に下回りさせることが容易となり、作業性が向上する。
また、下回り部分の振れやバラケも防止できるため、作業中および車両走行中に他の車載部品にワイヤハーネス40が干渉すること等も防止できる
Furthermore, in the assembly work of the wire harness 40, the outer routing portion 40a can be fixed to the lower retracting member 20 first, so that the wire harness 40 with brazing or the like can be easily lowered to an accurate shape and position. , Workability is improved.
Further, since the lower portion can be prevented from swinging and falling, it is possible to prevent the wire harness 40 from interfering with other in-vehicle components during work and traveling of the vehicle.

なお、本発明は前記実施形態に限定されるものではない。特に、ワイヤハーネス引き込み開口を本体ケース11の側面に設けて、下回り引込部材20を本体ケースに取り付ける構成としてもよい。   In addition, this invention is not limited to the said embodiment. In particular, the wire harness drawing opening may be provided on the side surface of the main body case 11 and the lower turn drawing member 20 may be attached to the main body case.
