Bus structure comprising an insulating support and a coated electric bus bar
First Claim
1. In electric bus structure:
- (a) a bus bar,(b) a post-type insulator supporting said bus bar and having an end surface facing said bus bar,(c) a coating of insulating material completely covering all external surfaces of said bus bar in the general region of said insulator,(d) a bracket of insulating material with a U-shaped cross-section mounted on said insulator and having a bight portion extending across said end surface and a pair of spaced-apart arms at opposite ends of said bight portion extending in a direction away from said insulator,(e) means clamping said bus bar to said bracket in a position between said arms without perforating said insulating coating comprising a clamping member of insulating material extending between said arms and attached thereto,(f) said bracket and said clamping member each having end surfaces located at points spaced apart along the length of said bus bar,(g) said bracket and said clamping member each having rib structure projecting toward said bus bar and providing the sole surfaces through which contact is made between the coating on said bus bar and the bracket and clamping member when the bus bar is clamped to said bracket,(h) said rib structure being spaced from each of said end surfaces by a substantial distance considered longitudinally of said bus bar so that there are present between said rib structure and said end surfaces shallow tunnels bounded by insulation and extending along the length of said bus bar adjacent said insulating coating.

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.

6. In electric bus structure:
-
(a) a bus bar, (b) a post-type insulator supporting said bus bar and having an end surface facing said bus bar, (c) a coating of insulating material completely covering all external surfaces of said bus bar in the general region of said insulator, (d) a bracket member of insulating material mounted on said insulator and having a portion extending across said end surface, (e) means clamping said bus bar to said bracket member comprising a clamping member of insulating material extending laterally across said bus bar between laterally opposed ends of said bracket member, (f) one of said members being of U-shaped cross-section and comprising spaced arms at its lateral edges on laterally opposite sides of said bus bar extending toward said other member, (g) said bracket member and said clamping member each having end surfaces located at points spaced apart along the length of said bus bar, (h) said bracket member and said clamping member each having rib structure projecting toward said bus bar and providing the sole surfaces through which contact is made between the coating on said bus bar and the bracket member and clamping member when the bus bar is clamped to said bracket member, (i) said rib structure being spaced from each of said end surfaces by a substantial distance considered longitudinally of said bus bar so that there are present between said rib structure and said end surfaces shallow tunnels bounded by insulation and extending along the length of said bus bar adjacent said insulating coating. - View Dependent Claims (7, 8)
