本考案は自動車などの電気配線に使用される電
気接続箱の排水構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drainage structure for an electrical junction box used for electrical wiring in automobiles and the like.
電気接続箱は、第４図に示すように、箱本体１
の下にコネクタカバー２が取付けられ、コネクタ
カバー２が電気接続箱の底壁となる。
The electrical connection box has a box body 1 as shown in FIG.
A connector cover 2 is attached below, and the connector cover 2 becomes the bottom wall of the electrical connection box.
箱本体１の内部には回路板（図示しない）及び
回路板の上に配設される表カバー（図示しない）
などが収容される。 Inside the box body 1 there is a circuit board (not shown) and a front cover (not shown) disposed on the circuit board.
etc. are accommodated.
コネクタカバー２の側壁にはワイヤーハーネス
挿入口３が設けられ、底壁には傾斜壁２ａが設け
られ、最も低い底壁２ｂの一端に排水口４が設け
られる。 A wire harness insertion port 3 is provided on the side wall of the connector cover 2, an inclined wall 2a is provided on the bottom wall, and a drain port 4 is provided on one end of the lowest bottom wall 2b.
従つて、電気接続箱の内部に浸入した水滴は第
５図の矢印５に示すように、傾斜壁２ａに沿つて
流れ、底壁２ｂに集められ、排水口４より落下し
て外部に排出される。 Therefore, water droplets that have entered the electrical junction box flow along the inclined wall 2a, collect on the bottom wall 2b, and fall through the drain port 4 to be discharged to the outside, as shown by arrow 5 in FIG. Ru.
排水口４の開口面積は、排出される水滴寸法よ
りも充分大きくして流れ易くすることが望ましい
が、排水口４を大きくすると逆に外部から水が浸
入する危険性が増加する。 It is desirable that the opening area of the drain port 4 is sufficiently larger than the size of water droplets to be discharged so that water can flow easily, but if the drain port 4 is made larger, the risk of water entering from the outside increases.
自動車が走行中には、電気接続箱に向つて風の
流れが生じ、風によつて運ばれる水滴が排水口４
を経て内部に浸入することがある。 While the car is running, wind flows toward the electrical junction box, and water droplets carried by the wind flow into the drain port 4.
may enter the interior through
これを避けるために排水口４の開口面積を極め
て小さくするとコネクタカバー２内の水が排出さ
れ難くなる。 In order to avoid this, if the opening area of the drain port 4 is made extremely small, the water inside the connector cover 2 will be difficult to drain.
そこで、第６図に示すように、排水口４の上部
に両端を側壁などによつて支持されて門型形状を
成す反射板６を設け、外部から浸入する水滴を反
射板６によつて遮蔽する方法が考えられるが、第
７図に示すように、反射板６と底壁２ｂとの〓間
寸法ｄを水滴Ｇの高さｈよりも大きくすると底壁
上の水滴Ｇは排除され易くなるが、外部から飛来
する水滴を遮蔽する効果が薄れる欠点を生じ、
又、第８図に示すように、〓間寸法ｄを水滴Ｇの
高さｈよりも小さくすると外部から飛来する水滴
を遮蔽する効果が高まるが内部の水滴Ｇが排出さ
れた難くなる欠点がある。 Therefore, as shown in FIG. 6, a gate-shaped reflector plate 6 with both ends supported by side walls or the like is provided above the drain port 4, and the reflector plate 6 blocks water droplets entering from the outside. However, as shown in FIG. 7, if the distance d between the reflection plate 6 and the bottom wall 2b is made larger than the height h of the water droplet G, the water droplet G on the bottom wall will be easily removed. However, it has the disadvantage that the effect of shielding water droplets flying from the outside is weakened,
Furthermore, as shown in Fig. 8, if the distance d is made smaller than the height h of the water droplets G, the effect of shielding water droplets from the outside will increase, but there is a drawback that it becomes difficult for the water droplets G inside to be discharged. .
以上のように、反射板による外部水滴遮蔽効果
と内部水滴排除効果とは相反する関係にあり、反
射板の高さを如何に変えても両効果を同時に満足
することができなかつた。 As described above, the effect of shielding external water droplets and the effect of eliminating internal water droplets by the reflecting plate are in a contradictory relationship, and no matter how the height of the reflecting plate is changed, it is not possible to simultaneously satisfy both effects.
本考案はかかる問題点に着目してなされたもの
で、内部水滴の排除効果を高めると同時に外部水
滴の浸入を防止することのできる排水構造を提供
するものである。 The present invention has been devised in view of these problems and provides a drainage structure that can enhance the effect of removing internal water droplets and at the same time prevent the intrusion of external water droplets.
本考案は、電気接続箱の底壁を構成するコネク
タカバーに上記底壁より突出する排水孔壁を設
け、該排水孔壁の下端部のうち車両進行方向側の
下端部が最も低くなるようにし、車両に搭載され
た電気接続箱の上記排水孔壁内部が車両の進行に
伴つて負圧となる排水構造とした。
In the present invention, a drain hole wall protruding from the bottom wall is provided in the connector cover constituting the bottom wall of the electrical connection box, and the lower end of the drain hole wall on the side in the vehicle traveling direction is the lowest. The drainage structure is such that the interior of the drainage hole wall of the electrical connection box mounted on the vehicle becomes negative pressure as the vehicle moves.
車両が前進方向に走行すると、電気接続箱には
車両走行方向と逆方向の風が吹き付けられる。
When the vehicle travels in the forward direction, wind in the opposite direction to the vehicle travel direction is blown onto the electrical junction box.
従つて、最下端部を有する排水孔壁が風を受け
ると共に、風と共に送られてくる水滴の遮蔽板と
なり、排水孔内の空気は外部に吸引されてコネク
タカバー内部の水滴の排出を助ける。 Therefore, the drain hole wall having the lowest end receives the wind and serves as a shielding plate for water droplets sent along with the wind, and the air inside the drain hole is sucked to the outside to help drain water droplets inside the connector cover.
本考案の実施例を図面を参照して説明する。 Embodiments of the present invention will be described with reference to the drawings.
なお、従来例と同一部品には同一符号を付す。 Note that the same parts as in the conventional example are given the same reference numerals.
第１図の斜視図に示すように、箱本体１の下に
組付けられるコネクタカバー２は傾斜壁２ａを有
し、最も低い底壁２ｂの一端に下方に突出する排
水孔壁７が設けられる。 As shown in the perspective view of FIG. 1, the connector cover 2 assembled under the box body 1 has an inclined wall 2a, and a drain hole wall 7 projecting downward is provided at one end of the lowest bottom wall 2b. .
排水孔壁７はコネクタカバー２内部より外部に
連通する排水孔８を有し、排水孔壁７の下端部
は、第２図に示すように、矢印９に示す車両進行
方向側の下端部が最も低くなる斜面１０を形成す
る。 The drain hole wall 7 has a drain hole 8 that communicates with the outside from the inside of the connector cover 2, and as shown in FIG. A slope 10 that is the lowest is formed.
実施例は斜面としたが車両進行方向側が低いも
のであれば斜面に変えて段付きとしてもよい。 In the embodiment, a slope is used, but if the side in the direction of vehicle movement is low, it may be stepped instead of a slope.
そして、排水孔８の上部には、第３図に示すよ
うに、一端をコネクタカバー２の側壁２ｃに支持
され他端を支持壁１１に支持された反射板５が設
けられる。 A reflecting plate 5 is provided above the drain hole 8, as shown in FIG. 3, with one end supported by the side wall 2c of the connector cover 2 and the other end supported by the support wall 11.
反射板６と底壁２ｂとの〓間寸法ｄは、矢印５
方向から底壁２ｂに流れてくる水滴Ｇの高さ寸法
ｈよりも小とする。 The distance d between the reflector 6 and the bottom wall 2b is indicated by the arrow 5.
It is assumed that the height dimension h of the water droplet G flowing from the direction toward the bottom wall 2b is smaller than the height dimension h.
従つて、中央部底壁２ｂ上の水滴Ｇは反射板６
と底壁２ｂとの間を通過し難く、又、コネクタカ
バー２の外部にある水滴が排水孔８を経てコネク
タカバー２内に浸入することも困難である。 Therefore, the water droplet G on the central bottom wall 2b is reflected by the reflection plate 6.
It is also difficult for water droplets on the outside of the connector cover 2 to enter the connector cover 2 through the drain hole 8.
以上のように構成された排水構造の作用を以下
に説明する。 The operation of the drainage structure constructed as above will be explained below.
電気接続箱の内部に浸入した水はコネクタカバ
ー２の傾斜面２ａに落下し、傾斜面２ａに沿つて
底壁２ｂ上に流れ落ちる。 The water that has entered the electrical connection box falls onto the inclined surface 2a of the connector cover 2, and flows down onto the bottom wall 2b along the inclined surface 2a.
底壁２ｂ上で停止した水滴Ｇの高さｈは反射板
６と底壁２ｂとの〓間寸法ｄよりも大きいため反
射板６に遮られて排水孔８に流れ込むことはでき
ないが、同様に、電気接続箱の外部に存在する水
滴も排水孔８を経由してコネクタカバー２の内部
に浸入することはない。 The height h of the water droplet G stopped on the bottom wall 2b is larger than the distance d between the reflection plate 6 and the bottom wall 2b, so it is blocked by the reflection plate 6 and cannot flow into the drain hole 8, but similarly Also, water droplets existing outside the electrical connection box will not enter the inside of the connector cover 2 via the drain hole 8.
車両が第２図に示す矢印９方向に前進すると、
車両の走行によつて生ずる風が矢印９方向の反対
方向に流れ、排水孔壁７の右側面に当る。 When the vehicle moves forward in the direction of arrow 9 shown in Figure 2,
Wind generated by the running of the vehicle flows in the opposite direction of the arrow 9 and hits the right side surface of the drain hole wall 7.
排水孔壁７の右側面は斜面１０によつて最も長
く形成されており、風及び風の中に含まれる水滴
の遮断壁となる。 The right side of the drainage hole wall 7 is formed by the slope 10 and has the longest length, and serves as a barrier against wind and water droplets contained in the wind.
一方、下端部が最も低い排水孔壁によつて負圧
を生じ、排水孔８内の空気が外部に吸引され、底
壁２ｂ上の水滴Ｇが反射板６の下をくぐつて排水
孔８内に強制的に排出される。 On the other hand, a negative pressure is generated by the drain hole wall whose lower end is lowest, the air inside the drain hole 8 is sucked to the outside, and the water droplets G on the bottom wall 2b pass under the reflection plate 6 and enter the drain hole 8. is forcibly ejected.
又、排水孔８内の空気は外部に吸引されている
ため、外部より水滴が排水孔８を経由してコネク
タカバーに浸入することはない。 Furthermore, since the air in the drain hole 8 is sucked to the outside, water droplets from the outside will not enter the connector cover via the drain hole 8.
かくして、コネクタカバー２の内部の気圧が低
下するが、電気接続箱には空気の入り込む小さな
〓間があるため、コネクタカバー２内に空気が補
充され、排水孔８内の空気が外部に吸引れて排出
される風の流れは保たれる。 As a result, the air pressure inside the connector cover 2 decreases, but since there is a small gap in the electrical junction box where air can enter, air is replenished inside the connector cover 2 and the air inside the drain hole 8 is sucked outside. The flow of air that is discharged is maintained.
車両が停止したときには、排水孔８内の空気の
流れも停止するが、反射板６の〓間ｄが狭いため
外部の水滴はコネクタカバー内に浸入することは
ない。 When the vehicle stops, the flow of air in the drain hole 8 also stops, but since the gap d between the reflectors 6 is narrow, external water droplets do not enter the connector cover.
本考案はコネクタカバーの底壁に下方に突出す
る排水孔壁を設け、排水孔壁の下端部を車両進行
側の下端部が最も低くなるようにしたため、車両
走行に伴つて排水孔壁内の排水孔の空気が外部に
吸引されるため、コネクタカバー内部の水滴は外
部に排出され易く、外部からはコネクタカバー内
部に水滴が浸入できない構造とした。
In this invention, a drain hole wall that protrudes downward is provided on the bottom wall of the connector cover, and the lower end of the drain hole wall is made so that the lower end on the vehicle traveling side is the lowest. Since the air in the drain hole is sucked to the outside, water droplets inside the connector cover are easily discharged to the outside, and the structure is designed to prevent water droplets from entering the connector cover from the outside.
かくして、従来から問題となつていた内部の水
滴の排水効果とこれと相反する外部水滴の遮蔽効
果を同時に満足することができるようになつた。 In this way, it has become possible to simultaneously satisfy the conventionally problematic drainage effect of internal water droplets and the contradictory effect of shielding external water droplets.
しかも、本考案の排水構造は極めて簡単であ
り、製造コストの上昇はほとんどなく、故障も少
ない等の利点がある。 Furthermore, the drainage structure of the present invention is extremely simple, has the advantage of hardly increasing manufacturing cost, and having fewer failures.
