Description

本発明の第一の態様は、電気部品が装着される箱本体と、該箱本体の開口部を覆う蓋体を備えた電気接続箱において、前記蓋体の開口端面における全周あるいは一部分には、前記箱本体の周壁の外周面に重ね合される外周側止水壁と、前記箱本体の前記周壁の内周面に重ね合される内周側止水壁が、前記蓋体の開口端面の周方向で互いに異なる部位に設けられていることを、特徴とする。 According to a first aspect of the present invention, there is provided an electrical junction box including a box body on which an electrical component is mounted and a lid that covers the opening of the box body. The outer peripheral side water stop wall superimposed on the outer peripheral surface of the peripheral wall of the box body, and the inner peripheral side water stop wall superimposed on the inner peripheral surface of the peripheral wall of the box main body are open end surfaces of the lid body. It is characterized in that they are provided at different sites in the circumferential direction.

このようなアッパカバー１４を箱本体１２の上方開口部に組み付ける際には、図５に示すように、アッパカバー１４の周壁４４の内周面が、箱本体１２の周壁３０の上端部分の外周面に重ね合されるように挿し入れられる。さらに、アッパカバー１４が箱本体１２側に押し込まれると、アッパカバー１４の弾性ロック片４６，４６の各ロック爪部４８が、箱本体１２のロック枠体３６に当接し、弾性ロック片４６，４６が内方に撓み変形して更なる押し込みが許容される。そして、ロック爪部４８，４８がロック枠体３６，３６を乗り越えて弾性ロック片４６，４６が弾性復帰されると、各ロック爪部４８がロック枠体３６に係合して、アッパカバー１４が箱本体１２の上方開口部への装着状態にロックされるのである。 When the upper cover 14 is assembled to the upper opening of the box body 12, as shown in FIG. 5, the inner peripheral surface of the peripheral wall 44 of the upper cover 14 is the outer periphery of the upper end portion of the peripheral wall 30 of the box body 12. It is inserted so as to overlap the surface. Further, when the upper cover 14 is pushed into the box body 12 side, the locking pawl 4 8 of elastic locking pieces 46, 46 of the upper cover 14 comes into contact with the locking frame 36 of the box body 12, elastic lock pieces 46 , 46 are deflected inward to allow further pushing. When the lock claw portions 48 and 48 get over the lock frame bodies 36 and 36 and the elastic lock pieces 46 and 46 are elastically restored, each lock claw portion 48 engages with the lock frame body 36 and the upper cover 14. Is locked in a state of being attached to the upper opening of the box body 12.

加えて、ロアカバー１６の底壁６６が、図４に示すように一方の端部から他方の端部に向かって下方傾斜する傾斜面６８を有しており、最下端となる他方の端部側には、電線導出孔６２や排水穴７０ａが設けられている。従って、外周側止水壁５８の形成領域からロアカバー１６内に水が浸入したとしても、傾斜面６８の傾斜に沿って電線導出孔６２や排水穴７０ａに導かれ、速やかな排水が促される。また、電線２１を伝って水が浸入し易い電線導出孔６２が、最下端となる他方の端部側に設けられている故、電線２１を伝ってロアカバー１６内部に浸入する水も箱本体１２へ至る前に速やかに排水されるのである。 In addition, the bottom wall 66 of the lower cover 16 has an inclined surface 68 inclined downward from one end portion toward the other end portion as shown in FIG. Are provided with a wire outlet hole 62 and a drain hole 70a. Therefore, even if water enters the lower cover 16 from the formation area of the outer peripheral side water blocking wall 58, it is led to the electric wire outlet hole 62 and the drain hole 70a along the inclination of the inclined surface 68, and prompt drainage is promoted. Further, since the wire lead-out hole 62 through which the water can easily enter through the electric wire 21 is provided on the other end side which is the lowermost end, the water that enters the lower cover 16 through the electric wire 21 also enters the box body 12. It is drained quickly before it reaches.
