CONNECTING BOLT CLAMP (VERSIONS) Russian patent published in 2019 - IPC H01R4/30 

FIELD: electric power engineering.

SUBSTANCE: invention relates to electric power industry, in particular to connecting bolt clamps intended for connection of non-insulated steel and aluminum, aluminum, copper wires and ropes. Clamp comprises housing 1 with seats 2 and bolts 3. Along edges of housing 1 there are inlet cylindrical cavities 4 and inner cylindrical cavity 7. Cavities 4 are made inside with notches 8, seats 2 are arranged in the form of two and more rows, providing with the help of bolts 3 wire clamp in cavities 4 and clamp of core 5 of wire in cavity 7, axes 9 of seats 2 of one row relative to other are arranged at angle (α) of more than 20 degrees but less than 45 degrees. Axes 9 of seats 2 are located at an angle (α) is more than 45 degrees, but less than 181 degrees. Seats 2 are arranged in the form of three and more rows, providing with the help of bolts 3 clamp of wire in cavities 4 and clamp of core 5 in cavity 7. Seats 2 are arranged not coaxially on different longitudinal axes 10 passing through centers of rifled seats 2, providing with the help of bolts clamp of wire in cavities 4 and clamp of core 5 in cavity 7.

EFFECT: clamp is simple in design and is characterized by wide range of functional industrial application.
