HIGH-TEMPERATURE COUPLING OF CABLE INPUT FOR SUBMERSIBLE MOTOR Russian patent published in 2019 - IPC H02G15/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to end connectors for cables in a liquid medium. Cable entry coupling for a submersible electric motor contains interconnected housing and shank, filled with compound, conductive cable wire with a plug tip, built into the block. Wire is passed through a through hole and is released on a part of its length from a lead protective sheath, worn on a tapered element. Coupling is made up of individual couplings (4) located at the end of each wire of a conductive cable. Each coupling includes housing (5), shank (6) and nipple (7) connected by means of a threaded connection. Housing is made with a through hole for passing wire (2) and has external conical element (10) to cover the lead protective sheath. On the end side of the nipple, facing the outer cone body element, a reciprocal internal conical element is provided, which provides sealing of the lead protective sheath placed between them.

EFFECT: invention provides high maintainability of the coupling, increased reliability and increased service life.
