<p>PROBLEM TO BE SOLVED: To employ vertical bus-bars which are made with a satisfactory yield in a junction box and to reduce the dimensions of the junction box. SOLUTION: A junction box 100 has a base module 10 and a fuse/relay module 11. Rectangular vertical bus-bars 13 are arranged in parallel with each other in an X-direction. Further, a plurality of wire connection blocks 15, in which a large number of external wire terminal connecting cavities 16 are arranged in parallel with each other in a Y-direction, are made to protrude from the outer surface of the base module 10. An X-Y lattice is composed of the vertical bus-bars 13 and the cavities 16, and the vertical bus-bars 13 are connected to wires w1 at prescribed cross points to form a circuit. On the other hand, side ends of bus-bars 41 and 42 in a fuse/relay module 11 are connected to the vertical bus-bars 13. A plurality of vertical bus-bar connection terminals 42a are formed on the one end of one bus-bar 42 and connected with the vertical bus-bars 13 by the splice.</p> |
