Abstract

An electrical connection box includes a box main body having an opening portion in an upper end portion at a time of installation, and an upper cover that blocks the opening portion at the time of installation. The box main body has an insertion wall portion continuously formed along an outer circumference of the box main body in the upper end portion at the outer circumference of the box main body. The upper cover has a groove portion continuously formed along an outer circumference of the upper cover in a lower end portion at the outer circumference of the upper cover. Here, the insertion wall portion is inserted into the groove portion from lower side when the opening portion of the box main body is blocked. At least one rib protruding downward from a bottom portion of the groove portion is formed in the groove portion.

First claim

What is claimed is:

1. An electrical connection box comprising:
a first housing member having an opening portion in an upper end portion at a time of installation; and
a second housing member that is positioned at an upper side with respect to the first housing member, and blocks the opening portion at the time of installation, wherein
the first housing member has an insertion wall portion continuously formed along an outer circumference of the first housing member in the upper end portion at the outer circumference of the first housing member,
the second housing member has a groove portion continuously formed along an outer circumference of the second housing member in a lower end portion at the outer circumference of the second housing member, the insertion wall portion being inserted into the groove portion from a lower side when the opening portion of the first housing member is blocked,
at least one rib protruding downward from a bottom portion of the groove portion is formed in the groove portion, and
both end portions of the rib in a direction perpendicular to an up-down direction and a direction in which the groove portion extends are connected to the second housing member, and a space is formed between the rib and the insertion wall portion in a state in which the second housing member closes the opening portion, wherein the rib and the insertion wall portion do not contact each other in the up-down direction in the state in which the second housing member closes the opening portion.

2. The electrical connection box according to claim 1 , wherein
the at least one rib is provided in plurality,
the groove portion has a plurality of sides, and a plurality of corner portions, each of the corner portions connecting a respective pair of the sides, and
each of the sides has at least one of the ribs.

3. The electrical connection box according to claim 2 , wherein
the ribs are arranged in a plurality of pairings such that each of the corner portions is interposed between the ribs of a respective one of the pairings.

4. A wire harness comprising:
an electric wire; and
an electrical connection box including a first housing member having an opening portion in an upper end portion at a time of installation, and a second housing member that is positioned at an upper side with respect to the first housing member, and blocks the opening portion at the time of installation, wherein
the first housing member has an insertion wall portion continuously formed along an outer circumference of the first housing member in the upper end portion at the outer circumference of the first housing member,
the second housing member has a groove portion continuously formed along an outer circumference of the second housing member in a lower end portion at the outer circumference of the second housing member, the insertion wall portion being inserted into the groove portion from a lower side when the opening portion of the first housing member is blocked,
at least one rib protruding downward from a bottom portion of the groove portion is formed in the groove portion, and
both end portions of the rib in a direction perpendicular to an up-down direction and a direction in which the groove portion extends are connected to the second housing member, and a space is formed between the rib and the insertion wall portion in a state in which the second housing member closes the opening portion, wherein the rib and the insertion wall portion do not contact each other in the up-down direction in the state in which the second housing member closes the opening portion.
