ABSTRACT:
Branch connection busbars to be firmly installed in upper and lower cases each have upper and lower series of branched tabs projecting upwardly and downwardly from the upper and lower lateral edges of the busbar, respectively, through tab connecting portions, with the upper and lower series of branched tabs staggered. The upper and lower cases are each provided at their opposing contact surfaces with seats. The branch connection busbars are first installed into the lower case with the upwardly projecting branched tabs held firmly by the seats of the lower case. At the same time the downwardly projecting branched tabs are passed through tab insertion holes in the lower case. As the upper case is assembled onto the lower case, the upwardly projecting branched tabs are inserted into the tab insertion holes in the upper case and the seats of the upper case are held against the bottom of the downwardly projecting branched tabs. Thus, the upper and lower branched tabs are firmly held between one case and the seats of another case, preventing the branched tabs and busbars from being dislocated by external force produced when external connectors are mounted or dismounted.
