Electric connection box
View Patent ↗The interior of a case body is partitioned into two chambers by a partition wall, and the two chambers communicate with each other via a communication passage defined by a notch formed in the partition wall. First and second covers are attached to the case body, and cover open sides of the two chambers, respectively. The first and second covers have lap portions, respectively, which cover an open end of the communication passage in overlapping relation to each other.
1. An electric connection box comprising:
a case body;
at least two chambers partitioned in said case body;
a notch defining a communication passage between adjacent two of said chambers formed on a partition wall partitioning said adjacent two chambers; and
first and second covers attached to said case body so as to cover open surfaces of said adjacent two chambers;
wherein said first and second covers have lap portions respectively, which cover an open surface of said communication passage such that said lap portions overlap each other above said communication passage,
wherein a first lap portion of said lap portions includes a projecting wall portion projecting from a peripheral edge portion of said first cover, and a bottomed groove portion formed on an inner edge of said projecting wall portion acting as a gutter for conveying water to an exterior of the chambers, and
a second lap portion of said lap portions includes a covering portion covering said projecting wall portion, and a bent retaining portion which is bent at an outer edge of said covering portion so as to be received in said groove portion.
2. An electric connection box according to claim 1 , wherein said first cover comprises a frame-like cover frame which has an internal space opening to the open surface and on which said first lap portion is formed, and a cover body which is attached to said cover frame so as to close the internal space.
3. An electric connection box according to claim 1 , wherein an interior of said case body is partitioned only into said two chambers by a single partition wall.
