1,109,712. Bus-bars. BROWN, BOVERI & CIE A.G. 11 May, 1966 [18 May, 1965; 21 Jan., 1966], No. 20846/66. Heading H1A. The laminated bus-bar shown of which the laminated sections are insulated from each other by synthetic resin is formed from identical laminated members 1 all of which carry connecting lugs 2, 3 in all the possible connecting positions, the surplus lugs being removed before assembly to form a composite bar as shown. The laminations may be glued and baked together. The central bend 5 may be applied to each lamination separately or the laminations may be clamped as at one end and bent as a whole. Lugs 2 may be bent over, drilled and cut to the same length (Figs. 5 and 6, not shown) and the ends of the laminations may be bent at right-angles to the length of the laminations to provide end terminals. The surplus connections are cut away by a die so set that the smallest required distance between lugs is produced by a single working stroke, larger intervals requiring several working strokes. The edges of the assembled bar may be sealed. In an alternative arrangement (Figs. 7, 9, not shown) each lamina conductor is cut from a strip by a tool which removes the surplus material and leaves only the required larger lugs while a further tool operating simultaneously cuts free the required smaller lugs. |
