SUPPORTING VIBRATION CLAMP Russian patent published in 2023 - IPC H02G7/05 

FIELD: electrical engineering.

SUBSTANCE: supporting clamps for suspending wires of overhead power lines. The supporting vibration-resistant clamp contains a shock absorber made of two parts put on the supported wire, a wire protector wound on the shock absorber, a power housing made of two halves installed around the protector and connected to each other by means of a threaded connections, as well as a suspension pivotally connected to the power housing. According to the invention, the suspension is made in the form of a bracket having a socket of a hinge-spherical connection with the pestle of the insulator rod, while coaxial pins with outer cylindrical surfaces are located at the open ends of the bracket. Each half is provided with a protrusion located on its outer surface. Blind grooves are made in the protrusions with the formation on the surface of the protrusion of non-closed coaxial internal cylindrical surfaces having power sections. The trunnions are located with the possibility of contact with their outer cylindrical surfaces with the power sections of the protrusions and are made with the possibility of bringing them into contact with the power sections of the protrusions by moving the bracket with the trunnions relative to the halves and inserting the trunnions into the grooves of the protrusions. In this case, the geometric axis of the coaxial trunnions crosses the supported wire, and the clamp is equipped with a lock-limiter that prevents the trunnions from leaving the grooves of the protrusions after the clamp is assembled.

EFFECT: facilitating the mounting of the clamp, increasing the reliability of the wire suspension with increased structural strength and vibration resistance.
