DEVICE FOR CABLE CONNECTION TO FLOW STRING Russian patent published in 2007 - IPC E21B17/00 

FIELD: oil and other fluids production, particularly safety devices for cable supply lines of submersible pump motors.

SUBSTANCE: device comprises body with longitudinal groove for cable lying, upper and lower clamping clips, hinge assemblies to secure clips on body, projections formed on upper and lower cylindrical body parts. Gaps for clip sliding along body are provided between hinges of hinge assemblies. Each of upper and lower clamping clips is provided with one figured opening formed in side thereof opposite to hinge assemblies. Each opening is partly defined by surface inclined to contoured clip line. Upper edges of inclined surfaces touch inner surfaces of extensions formed on the body. One stop tab is created in each clip opening from hinge assembly side. Each stop tab adjoins body extensions from the side of clutch, which connects flow string pipes. The stop tabs are parallel to extensions. At least one cut is created in partitions defined by parallel ends of clamping clips in sides opposite to hinge assemblies and by longitudinal surfaces partly defining openings from clutch side. The cuts adjoin transversal surface, which defines opening, and have convex areas facing out of clamping clips. Cut width exceeds width of stop created on body.

EFFECT: simplified structure, increased reliability of device connection to flow string, prevention of cable sagging in space between longitudinal body groove bottom and connection clutch.
