ABSTRACT:
This electric bus structure comprises a bus bar having a coating of insulating material, an insulator for supporting the bus bar, and a bracket of insulating material having a U-shaped cross-section mounted on the insulator and having a pair of spaced-apart arms between which the bus bar is positioned. The bus bar is clamped to the bracket by clamping means comprising a clamping member of insulating material extending between the arms. The bracket and the clamping member each have rib structure projecting toward the bus bar and providing the sole surfaces through which contact is made between said coating and the bracket and clamping member when the bus bar is clamped to the bracket. This rib structure is spaced from the longitudinally-spaced end surfaces of the bracket and clamping member by a substantial distance considered longitudinally of the bus bar so that there are present between the rib structure and said end surfaces shallow tunnels bounded by insulation and extending along the length of the bus bar adjacent said insulating coating.
