Abstract:
Methods of making insulated bus bars using flat, non-selfconforming insulating film as insulation. One or more strips of insulating film are fed through various work stations in which the strips are formed into a generally U-shaped cross section, heated on the inside of the U-shaped cross section, formed into a sleeve corresponding to the shape of a bus bar and having overlapping longitudinal edge portions, heated on the outside, cooled, and cut to length. A bus bar is then inserted transversely in the formed sleeve.
Abstract:
THE TERMINAL STRAP INCLUDES A REAR PLATFORM NORMALLY MOUNTED ADJACENT A REAR WALL OF AN ENCLOSURE FOR THE SWITCH, A FRONT PLATFORM, AND A CONNECTING PORTION JOINING THE FRONT AND REAR PLATFORMS. A STATIONARY CONTACT JAW MEMBER IS SECURED TO THE REAR PLATFORM. A PAIR OF CONNECTORS, EACH INCLUDING A CONNECTOR BODY HAVING A CLAMPING SCREW
THREADEDLY MOUNTED THEREIN, ARE SECURED TO THE FRONT PLATFORM RESPECTIVELY BY A PAIR OF CAPTIVE BOLTS HAVING HEAD PORTIONS DISPOSED REARWARDLY OF THE FRONT PLATFORM RESPECTIVELY ON OPPOSITE SIDES OF THE CONNECTING PORTION IN NONROTATABLE RELATIONSHIP THEREWITH.
