BUS BAR STRUCTURE FOR ELECTRICAL CONNECTING BOX

PROBLEM TO BE SOLVED: To provide a bus bar structure for electrical connection box which can prevent the occurrence of leakage currents, even if burrs are produced in a buss bar forming process. SOLUTION: In this bus bar structure, in which a plurality of bus bars 11 and 11 which are obtained by punching a conductive plate are accomodated respectively and laid planarly in groove sections 13B which are demarcated by a rib 13A formed on the surface of an insulating substrate 13, the bus bars 11 are arranged in the groove sections 13B, so that the faces of the bars 11 opposite to their punching start faces 11A comes into contact with the bottoms of the groove sections 13B. Even if burrs 12 are produced in the end sections of the bars 11, the burrs 13 will not exist on the rib 13A, and the occurrence of leakage currents, which are generated when the burrs 12 come closer to each other, can be prevented.
