Electric junction box and its assembling process

An electric junction box in which a plurality of printed boards stepwise disposed is accommodated inside an upper case and a printed board holding case, with said printed boards spaced at intervals;

• a periphery of an upper-position printed board is projected beyond a periphery of a lower-position printed board;
• electric conductors are arranged side by side on a peripheral portion projected from said lower-position printed board;
• and terminal holes each having a conductive layer, connected with one of said electric conductors, formed on an inner peripheral surface thereof are arranged side by side on said peripheral portion projected from said lower-position printed board,
• a peripheral wall of said printed board holding case is formed stepwise in conformity to a stepwise disposition of a plurality of said printed boards;
• and insertion through-holes through which press fit terminals are inserted respectively are formed side by side on each horizontal stepped part;
• each of said press fit terminals is formed by bending a rod-shaped material made of conductive metal and has a long first vertical part, a horizontal part bent at a lower end of said first vertical part, and a short second vertical part bent upward at a leading end of said horizontal part;
• and
• a plurality of said press fit terminals is disposed along said peripheries of said printed boards;
• said horizontal parts of said press fit terminals are disposed along a lower surface of each of said horizontal stepped parts of said printed board holding case, and said second vertical part of each of said press fit terminals is inserted through an insertion through-hole of each of said horizontal stepped parts and pressed into each of said terminal holes of said lower-position printed boards to thereby electrically bring said second vertical part into contact with said conductive layer;
• and said first vertical part of each of said press fit terminals is disposed along a vertical outer surface of a stepwise part of said printed board holding case, and an upper portion of said first vertical part is pressed into one of said terminal holes of said upper-position printed board to thereby electrically bring said first vertical part into contact with said conductive layer.
