Background technology
Strain clamp is widely used in corner in power system, continues and the connection of terminal, the wedge of especially built-in voussoir
Shape strain clamp has more preferable grip, significant effect to cable, therefore has very extensive use range.Strain clamp makes
Used time must ensure the stability of wire clamp, avoid it that loosening occurs and drop, not so can bring very big security incident.At present,
Bolt for fixing clamper both sides arm-tie is common bolt, however it remains bolt is in use with overall wire clamp
Rock, and occur to loosen the potential safety hazard to drop.Therefore, it should a kind of new technical scheme is provided and solved the above problems.
The content of the invention
The purpose of the present invention is：For above-mentioned deficiency, there is provided a kind of rational in infrastructure, good wedge tension resisting line of using effect
Folder.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of wedge strain resistance cable clamp, including wedge-shaped housing, the wedge-shaped enclosure interior are the wedge cavities for placing voussoir,
It is metallic channel in the voussoir, the left and right side of the wedge-shaped housing is equipped with bolt hole, and passes through fixing bolt and internal wedge
Block is connected, and the both sides of the wedge-shaped housing wide end are respectively equipped with an arm-tie, and one end of two arm-ties will by nut
It is fixed on the both sides of wedge-shaped housing wide end, and the other end of two arm-ties is consolidated also by nut and fastening bolt
Fixed, the nut is the inserted stop nut of spring, is provided with a connecting rod between two arm-ties, is provided with the connecting rod
Bump leveller.
Further technical scheme is：
The inserted stop nut of spring includes nut body and spring, is formed with the nut body up big and down small
Step through hole, and the hypomere of step through hole is internal thread hole, and epimere is unthreaded hole, and the upper surface of the nut body has
Back-up ring, and back-up ring is located at the top of unthreaded hole, the spring is inlaid in unthreaded hole by back-up ring, and the lower end of the spring prolongs upwards
The top for extending back-up ring forms spring release end.
The bump leveller is dynamic vibration absorber.
Due to the application of above-mentioned technical proposal, the present invention has the following advantages that compared with prior art：
1st, wedge strain resistance cable clamp of the invention, it is the inserted stop nut of spring to design the nut used, and the nut only has
Staff rotates backward spring release end, can just remove, and avoids the generation that nut is loose in use, takes off, falls phenomenon,
And install convenient, without installing spring washer or stop washer, operating efficiency can be improved.
2nd, wedge strain resistance cable clamp of the invention, a connecting rod is provided between arm-tie, bump leveller is provided with connecting rod, its
Strain clamp can be absorbed, and in height, due to extraneous factor, caused vibration is either rocked in the air, is advantageous to keep the steady of arm-tie
It is qualitative, the firmness that arm-tie is fixed then is improved, reduces accident odds.
