ABSTRACT:
A branch junction box having an upper case and a lower case, with a plurality of connector insertion portions provided on the upper case. A plurality of parallel busbar accommodating grooves are formed in the lower case. A plurality of busbars are installed in the busbar accommodating grooves and have branched tabs which project upwardly via tab connecting portions into the connector insertion portions. The tab connecting portions include a rising piece extending upwardly from one edge of the busbar and a tab connecting piece extending laterally on one or both sides of the rising piece. The tab connecting pieces are bent at right angles to the plane of the busbar so that the branched tabs on the connecting pieces protrude sideways from the busbar. The tab connecting pieces are formed with the upwardly projecting branched tabs. An insulating plate is formed with a plurality of insertion slits at positions corresponding to the tab connecting portions of the busbars to pass and project the branch tabs and tab connecting portions through the insertion slits of the insulating plate. The insulating plate is slid laterally relative to the branched tabs to a position where it is securely held between the busbars and the tab connecting portions.
