<p>PROBLEM TO BE SOLVED: To enhance compatibility to circuit modification in a junction box. SOLUTION: A vertical bus bar 13 in X direction is orthogonal, in lattice, to rows of electric-wire connection blocks 15 in which multiple electric-wire terminal connection cavities 16 are protruded side by side in Y direction on the outside surface of a case, with the vertical bus bar 13 connected to an electric wiring w at a required intersection to form a circuit. Ribs 19-1, 19-1, 19-2, and 19-2 are protruded to oppose each other at a prescribed position on both sidewalls of a groove 12a formed inside a case 12 to house the vertical bus bar 13. A long regular bus bar 13-1 is press-fitted and secured between ribs 19-1, etc., while a short non-regular bus bar 13-2 is held by abutting its tip 13a-2 against the rib 19-1, etc., and positioned for fixing.</p> |
