DEVICE FOR POWER CORD CONNECTION TO PRODUCTION STRING Russian patent published in 2005 - IPC

FIELD: oil production, particularly to secure current-conducting cable to production string during oil production with the use of pump.

SUBSTANCE: device has integrally formed body with longitudinal groove for receiving power cable, which supplied power to electric drive. Upper and lower body parts are provided with upper and lower lids. Each lid is secured to hinge and has fastening means, which connects thereof to upper and lower body parts correspondingly. Side body parts are made as flanges. Inner diameter of flange wall is equal to outer diameter of production string. The flanges are provided with depressions to install thereof on production string coupling. One flange is provided with two pins for lid connection. The pins are located close to side wall of longitudinal groove for cable. Another flange is provided with rib arranged, for instance, in parallel to groove bottom and extending past the dimensions of lid fastening means in assembled position. Above lids have thickness lesser than difference between outer radius of the coupling and production string radius. The lids may be resiliently deformed during installation thereof on the coupling and cover production string for production string perimeter part defined by angle exceeding 180°.

EFFECT: increased reliability and simplified assemblage.
