<p>PROBLEM TO BE SOLVED: To simplify the circuit configuration of a junction box. SOLUTION: On one surface of an insulating board 20 to be laminated and arranged in a junction box 10, distributing electric wires 21 are arranged in parallel, and their both ends are projected from the end brims of the insulating board. The electric wires 21 are welded to electric wires or bus-bars 22 in the shape of strips of fancy paper arranged in parallel on the other surface of the insulating board in directions perpendicular to the electric wires, at required crossing positions through openings 20a of the insulating board 20, to obtain a required circuit shape. Electric wires, which are arranged on insulating boards of different layers and are required to be connected for forming a circuit, are welded to each other at portions which are protruded from the insulating boards 20.</p> |
