<p>The assembly consists of a clamping piece (3) with a threaded shank (9). The shank passes through a hole (2) in part of the line holder (1) or similar. A nut (10) screws onto the shank and draws the clamping piece towards the holder part so that the lightning conductor (22) is sandwiched and held between clamping piece and holder part. Numerous variations on this basic design are described and all permit rapid and easy fixing of conductors of various diameters. If the lightning conductor is flat, the clamping piece is L-shaped with one limb forming a flat face that presses against the conductor and the other limb forming the threaded piece may be an L-shaped hook with a curved limb hooking around the conductor or it may consist of a post with a sloping into which the conductor fits. Alternatively, the clamping part of the clamping piece is separate from the threaded shank and loosely coupled to it in a variety of ways, e.g. a pivot pin or a hexagonal head.</p> |
