Abstract
The utility model provides an overhead suspension wire clamp, comprising a suspension frame whose bottom is in a U-shape, a buffering dead ring with variable diameters sleeved in the suspension frame, and a compression bolt used to extrude the buffering dead ring disposed on an opening end of the suspension frame. Rubber ring is preferably chosen for the dead ring. An axial directional cut which can unfold the wire clamp is disposed on a side corresponding to the bolt. The buffering dead ring with variable diameters is sleeved in the suspension frame, so certain flexibility is maintained while the wire clamp has relatively good tensile strength. The buffering dead ring protects optical fibers and plays a role of auxiliary damping. The rubber ring is preferably chosen for the dead ring, and a rubber material has good corrosion resistance and long service life. The side corresponding to the bolt on the dead ring is provided with the axial directional cut which is used to unfold the wire clamp. A power transmission line can be installed when the bolt is screwed off and the rubber ring is broken, so wiring is convenient. Total mass of the overhead suspension wire clamp is low and structure is simple. Special-purpose tools are not needed when the wire clamp is assembled. The wire clamp firmly fixes circuits, and is economical and practical. The overhead suspension wire clamp can be used for corners of power transmission lines, splicing and connection of terminals.
