Abstract

A branch box ( 100 ) includes: a branch portion ( 21 ) branching a power path ( 205 A) into at least two branch paths ( 206 A, 207 A); a fuse ( 60 ) located on at least one of the branch paths; a conductive member ( 33 ) connecting the branch portion and the branch path having the fuse; a first housing portion ( 11 ) receiving the fuse and closing its opening with a lid portion ( 81 ) to define a housing space; and a second housing portion ( 12 ) receiving the branch portion. The first housing portion is sealed with a first sealing material ( 85 ) filling a gap between the lid portion and the opening and is out of contact with the fuse. The second housing portion is sealed with a second sealing material ( 86 ) independent from the first sealing material. The conductive member passes through a partition wall ( 25 ) separating the first housing portion and the second housing portion.

First claim

The invention claimed is:

1. A branch box branching electric power supplied from a power source to a plurality of objects to be supplied with the electric power, the branch box comprising:
a branch portion branching a power path connecting to the power source into at least two branch paths;
a fuse located on at least one of the branch paths;
a conductive member connecting the branch portion and the branch path having the fuse;
a first housing portion receiving the fuse, the first housing portion having a box shape with an opening on one surface, the opening being closed by a lid portion to define a space for housing the fuse inside the first housing portion; and
a second housing portion receiving the branch portion,
the first housing portion being sealed with a first sealing material filling a gap between the lid portion and the opening and being out of contact with the fuse,
the second housing portion being sealed with a second sealing material independent from the first sealing material, and
the conductive member passing through a partition wall separating the first housing portion and the second housing portion.

2. The branch box according to claim 1 , wherein
the first sealing material is made from a material to allow unsealing of the first sealing material easier than unsealing of the second sealing material.

3. The branch box according to claim 1 , wherein
the second sealing material is in contact with the branch portion.

4. The branch box according to claim 1 , wherein
the conductive member is press-fitted in an insertion hole through the partition wall.
