<p>PROBLEM TO BE SOLVED: To prevent an electrical junction box from being overheated and downsize it by the best layout of relays and fuses. SOLUTION: A hybrid printed circuit board with a conductor fixed on one surface and a bus bar fixed on the other surface is provided as an inner part circuit body of this electrical junction box. A heavy-current circuit serving as a power input is formed by the bus bar and mid- and small current circuits serving as outputs are formed by the conductor on the reverse surface side. Relay blocks with the relays mounted in a line are, at regular intervals provided in a plurality of rows on the bus bar mounting side, a fuse block with terminals connected to the fuses protrudingly attached in a line is provided between the relay blocks, and the bus bar is disposed between the relay block and the fuse block for regularly repeating its arrangement pattern.</p> |
