Description

Technical Field

[0001] The utility model relates to the technical field of parallel groove wire clamps, in particular to an anti-loosening parallel groove wire clamp. Background Art

[0002] When laying power cables, it is often necessary to parallel the power cables. The existing method generally uses parallel groove wire clamps for connection. Parallel groove wire clamps are used to connect small and medium-section aluminum stranded wires or steel-core aluminum stranded wires and steel stranded wires of overhead lightning conductors at positions that do not bear tension. They are also used for jumper connections of non-straight poles and towers. Power engineering materials (metal fittings) are used to connect conductors to each other, mainly for power line projects.

[0003] However, when the existing bolt-type parallel groove wire clamp is used to fix the cable, a gap may be formed between the conductor and the parallel groove wire clamp due to thermal expansion and contraction, which may easily cause the bolt tightening force to become unstable and loose, resulting in an increase in the contact resistance of the connection point.
