Electric connection box
View Patent ↗An electric connection box includes a frame, a lower cover that covers the lower surface of the frame, and at least one block that is attached in the frame and disposed at a position along a peripheral wall of the frame. An electric wire that is connected to a component attached to the block out of the blocks is drawn horizontally from the block toward inside the frame.
1. An electric connection box comprising:
a frame;
a lower cover configured to cover a lower surface of the frame; and
a plurality of blocks configured to be attached in the frame and disposed at a position along a peripheral wall of the frame, the plurality of blocks being arranged in a vertical direction so as to include an uppermost block and a lowermost block, each block having a component attached thereto, wherein
a first electric wire that is connected to the component attached to the lowermost block is drawn horizontally from a lower surface side of the block as the first electric wire exits the block toward inside the frame and the drawn first electric wire proceeds toward a direction in which the first electric wire has been drawn, and
a second electric wire that is connected to the component attached to the uppermost block is drawn vertically from a lower surface side of the uppermost block as the second electric wire exits the uppermost block toward inside the frame.
2. The electric connection box according to claim 1 , wherein
an upper cover covers an upper surface of the frame.
3. The electric connection box according to claim 2 , wherein
the frame, the upper cover, the lower cover, and the plurality of blocks are made of materials that include synthetic resins.
4. The electric connection box according to claim 1 , wherein
the peripheral wall has a double wall structure constructed of an outer side wall and an inner side wall.
5. The electric connection box according to claim 1 , further comprising:
a relay and a relay terminal attached to at least one of the plurality of blocks, wherein
the relay terminal is electrically connected to one terminal part of the relay.
6. The electric connection box according to claim 5 , wherein
a terminal connected to an end of at least one of the first electric wire and the second electric wire is electrically connected to other terminal part of the relay.
7. The electric connection box according to claim 1 , further comprising:
at least one fuse and at least one bus bar attached to at least one of the plurality of blocks, wherein
a terminal connected to an end of at least one of the first electric wire and the second electric wire is electrically connected to one terminal part of respective one of the at least one fuse.
8. The electric connection box according to claim 1 , wherein
the lowermost block is disposed on the lower surface of the frame.
9. The electric connection box according to claim 1 , wherein
the uppermost block is disposed on an upper surface of the frame.
10. An electric connection box comprising:
a frame;
an upper cover configured to cover an upper surface of the frame;
a lower cover configured to cover a lower surface of the frame; and
at least one block configured to be attached in the frame and disposed at a position along a peripheral wall of the frame, wherein
an electric wire that is connected to a component attached to the block is drawn horizontally from the block toward inside the frame.
