Abstract
An anti-short bushing, for use between a tubular metal sheath and an electrical conductor carried within the metal sheath, comprising a tubular insulative unit configured to be inserted between the sheath and the conductor. The tubular insulative unit is formed as a single molded piece having three connected segments. Two of the segments are generally semi-cylindrical and each has a shoulder projecting radially therefrom at one end. The two segments are connected by an elongated hinge which permits them to be folded relative to one another to form a tubular configuration with their shoulders forming a partial circumferential shoulder. The third segment is connected to the elongated hinge by a second hinge to permit the third segment to be rotated to project radially outwardly so as to form with the two shoulders of the other two segments a complete circumferential shoulder.
