Electrical junction box
View Patent ↗An electrical junction box of the present invention includes a frame ( 11 ) in which a storing box B is formed which has a unit storing room ( 20 ) in which an electronic control unit ( 63 ) is accommodated, and an upper cover ( 15 ) which is assembled to the side of the frame ( 11 ) where a accommodating port ( 20 a ), which becomes an entrance when the electronic control unit ( 63 ) is accommodated in the unit storing room ( 20 ), is formed so that the accommodating port ( 20 a ) is closed.
1. An electrical junction box, comprising:
a frame comprising a first sidewall, a second sidewall and a frame separating wall, the first sidewall and the second sidewall defining a storing box, wherein at least a portion of the first sidewall and the frame separating wall define a unit storing room configured to accommodate an electronic control unit, the second sidewall being spaced apart from the unit storing room; and
an upper cover which is assembled to one side of the frame where an accommodating port is formed so that the upper cover closes the accommodating port, the accommodating port being an entrance for accommodating the electronic control unit in the unit storing room,
wherein the frame separating wall extends farther toward the upper cover in a cover-attachment direction than the second sidewall, and
wherein the first sidewall, the second sidewall and the frame separating wall at least partially overlap in a direction perpendicular to the frame separating wall.
2. The electrical junction box according to claim 1 , wherein:
the upper cover includes an upper cover body which closes the side of the frame where the accommodating port is formed, and a cover separating wall which is protruded to the frame from an inner surface of the upper cover body opposing the frame, and
the accommodating port is covered by the upper cover body and the cover separating wall.
3. The electrical junction box according to claim 2 , wherein:
the cover separating wall is protruded towards an edge of the frame separating wall, and
a distal end of the separating wall contacts the edge of the frame separating wall.
4. The electrical junction box according to claim 3 , wherein
the cover separating wall is formed with a reinforcing rib having a ridge shape along a direction in which the upper cover is assembled to the frame.
5. The electrical junction box according to claim 1 , wherein:
a distal end of the first sidewall in the cover-attachment direction contacts an inner surface of the upper cover opposing the frame, the distal end extending farther toward the upper cover than the second sidewall in the cover-attachment direction, and
wherein the first sidewall and the second sidewall define exterior sidewalls of the electrical junction box.
6. The electrical junction box according to claim 5 , the first sidewall comprising another distal end in the cover-attachment direction opposite to the distal end, the other distal end of the first sidewall extending farther away from the upper cover than the second sidewall.
7. The electrical junction box according to claim 1 , wherein the frame separating wall and a further frame separating wall separate the unit storing room from a connector storing frame, the further frame separating wall being disposed in an interior of the electrical junction box.
