Then, the bolt 10 is screwed into the nut of the terminal mounting portion through the screw portion in the hole 12. Thus, the terminal fitting 3 is fixed to the terminal mounting portion. Then, the electric wire 18 and the electric wire connection part 15 of the terminal metal fitting 3 are accommodated in the concave groove 14.

そして、サイドカバー４の係止部２１を矢印Ｋに沿って係止受け部９に近づけて、当該係止受け部９に係止させて、サイドカバー４を凹溝１４を塞いだ格好で箱本体２に取り付ける。こうして、電線１８をサイドカバー４と凹溝１４の底壁３０との間に位置付けて、前述した構成の電気接続箱１が組み立てられる。そして、電気接続箱１は、箱本体２の下面にワイヤハーネスのコネクタを嵌合するなどして、上面２ａが上方に位置しかつ下面が下方に位置した状態で自動車に搭載され（配され）るとともに、箱本体２にロアカバー及びアッパカバーが取り付けられる。そして、電気接続箱１は、自動車の電子機器と、ヒュージブルリンクやリレー５などの電気部品などとを、予め定められたパターンにしたがって、互いに電気的に接続する。   Then, the locking portion 21 of the side cover 4 is brought close to the locking receiving portion 9 along the arrow K and is locked to the locking receiving portion 9 so that the side cover 4 is closed with the groove 14 closed. Attach to the main body 2. Thus, the electric connection box 1 having the above-described configuration is assembled by positioning the electric wire 18 between the side cover 4 and the bottom wall 30 of the concave groove 14. The electrical connection box 1 is mounted (arranged) on the automobile with the upper surface 2a positioned upward and the lower surface positioned downward, such as by fitting a wire harness connector to the lower surface of the box body 2. In addition, a lower cover and an upper cover are attached to the box body 2. And the electrical junction box 1 electrically connects the electronic device of a motor vehicle, electrical parts, such as a fusible link and the relay 5, with each other according to a predetermined pattern.

本実施形態によれば、サイドカバー４の浸入防止部２２が本体部１９の縁部から立設した奥立設壁２３と、奥立設壁２３の先端から外側に延在した外側延在壁２４と、外側延在壁２４の先端から立設しかつ奥立設壁２３と間隔をあけて平行な手前立設壁２５とを備えているので、サイドカバー４の本体部１９と箱本体２の凹溝１４の内面との間から箱本体２内に浸入した液体がこれらの壁２３，２４，２５間に形成された空間に浸入した後に手前立設壁２５に衝突する。このために、当該液体の勢い（圧力）を低下させて、当該液体が手前立設壁２５を越えて箱本体内に浸入しにくくなる。よって、箱本体２の上面２ａに取り付けられた端子金具３やリレー５、ヒュージブルリンクなどへの液体の付着の防止を図ることができる。   According to this embodiment, the intrusion prevention part 22 of the side cover 4 stands upright from the edge of the main body part 19, and the outer extending wall extends outward from the tip of the upright wall 23. 24, and a front standing wall 25 that is erected from the tip of the outer extending wall 24 and that is parallel to the deeper erected wall 23 with a space therebetween, so that the main body 19 of the side cover 4 and the box main body 2 The liquid that has entered the box body 2 from between the inner surface of the concave groove 14 enters the space formed between the walls 23, 24, 25 and then collides with the front standing wall 25. For this reason, the momentum (pressure) of the liquid is reduced, so that the liquid does not easily enter the box body beyond the front standing wall 25. Therefore, it is possible to prevent liquid from adhering to the terminal fitting 3, the relay 5, the fusible link and the like attached to the upper surface 2 a of the box body 2.

また、箱本体２に設けられた防止部収容部７が、外壁６から立設した本体側奥立設壁２６と、本体側奥立設壁２６の先端から凹溝１４の内側に延在した内側延在壁２７と、内側延在壁２７の先端から立設しかつ浸入防止部２２の奥立設壁２３と間隔をあけた本体側手前立設壁２８と、を備えているので、手前立設壁２５を乗り越えた液体がこれらの壁２６，２７，２８間に形成された空間に浸入した後に本体側手前立設壁２８に衝突する。このために、手前立設壁２５を越えた液体が本体側手前立設壁２８に衝突して、当該液体の勢い（圧力）を更に低下させる。このために、当該液体が本体側手前立設壁２８を越えて箱本体２内に浸入することを防止できるので、近年発生する豪雨時にもより確実に箱本体２の上面２ａに取り付けられた端子金具３やリレー５、ヒュージブルリンクなどへの液体の付着の防止を図ることができる。   In addition, the prevention portion accommodating portion 7 provided in the box body 2 extends from the outer wall 6 to the main body side upright wall 26 and from the front end of the main body side upright wall 26 to the inside of the groove 14. Since it is provided with an inner extending wall 27 and a main body side front standing wall 28 that is erected from the tip of the inner extending wall 27 and spaced from the deeper wall 23 of the intrusion prevention unit 22, The liquid that has climbed over the standing wall 25 enters the space formed between these walls 26, 27, and 28 and then collides with the front side standing wall 28. For this reason, the liquid that has passed the front standing wall 25 collides with the main body side standing wall 28 to further reduce the momentum (pressure) of the liquid. For this reason, since the liquid can be prevented from entering the box main body 2 beyond the main body-side near-standing standing wall 28, the terminal attached to the upper surface 2a of the box main body 2 more reliably even in the case of heavy rain that occurs in recent years. It is possible to prevent liquid from adhering to the metal fitting 3, the relay 5, the fusible link, and the like.

さらに、浸入防止部２２がサイドカバー４の端子金具３が取り付けられる箱本体２の上方に位置付けられる上面２ａ寄りの端部に設けられているので、浸入防止部２２手前立設壁２５に衝突して勢いが低下された水が速やかに下方に流れて、前述した上面２ａの近傍からの液体の侵入を防止できる。したがって、当該液体が端子金具３に付着することを防止できる。   Further, since the intrusion preventing portion 22 is provided at the end near the upper surface 2a positioned above the box body 2 to which the terminal fitting 3 of the side cover 4 is attached, the intrusion preventing portion 22 collides with the standing wall 25 in front. Thus, the water whose momentum has been reduced can quickly flow downward to prevent liquid from entering from the vicinity of the upper surface 2a. Therefore, the liquid can be prevented from adhering to the terminal fitting 3.

また、本発明では、図７に示すように、防止部収容部７が中間突起２９を更に備えていてもよい。なお、図７において、前述した実施形態と同一部分には、同一符号を付して説明を省略する。   Moreover, in this invention, as shown in FIG. 7, the prevention part accommodating part 7 may further be provided with the intermediate protrusion 29.

Is formed constant in the longitudinal direction). The intermediate protrusion 29 is erected from the outer wall 6 toward the back of the box body 2 along a direction orthogonal to the surface 6 a of the outer wall 6. The intermediate protrusion 29 is disposed in parallel with the rear standing wall 23 and the front standing wall 25 of the side cover 4 attached to the box body 2, and the rear standing wall 23, the outer extending wall 24, and the front standing wall 25. And are spaced apart from all.

この図７に示す場合には、防止部収容部７が奥立設壁２３と手前立設壁２５との間に設けられる中間突起２９を更に備えているので、サイドカバー４の本体部１９と箱本体２の凹溝１４の内面との間から箱本体２内に浸入した液体が手前立設壁２５に加えて中間突起２９にも衝突する。このために、当該液体の勢い（圧力）を確実に低下させることができる。よって、箱本体２の上面２ａに取り付けられた端子金具３やリレー５、ヒュージブルリンクなどへの液体の付着の防止を確実に図ることができる。   In the case shown in FIG. 7, the prevention portion accommodating portion 7 further includes an intermediate protrusion 29 provided between the deep standing wall 23 and the front standing wall 25. The liquid that has entered the box body 2 from between the inner surface of the concave groove 14 of the box body 2 collides with the intermediate projection 29 in addition to the front standing wall 25. For this reason, the momentum (pressure) of the liquid can be reliably reduced. Therefore, it is possible to reliably prevent the liquid from adhering to the terminal fitting 3, the relay 5, the fusible link and the like attached to the upper surface 2 a of the box body 2.

また、前述した実施形態では、浸入防止部２２を本体部１９の上面２ａ寄りの端部に設けたが、本発明では、浸入防止部２２を本体部１９の上面２ａ寄りの端部に少なくとも設ければ、当該浸入防止部２２を本体部１９の上面２ａ寄りの端部以外の部分に勿論設けてもよい。即ち、浸入防止部２２の長さを適宜変更してもよい。   In the above-described embodiment, the intrusion prevention unit 22 is provided at the end of the main body 19 near the upper surface 2a. However, in the present invention, the intrusion prevention 22 is provided at least at the end of the main body 19 near the upper surface 2a.
