RELEASABLE LEAK-TIGHT ELECTRIC CONNECTOR OF WET CONTACT TYPE FOR ELECTRIC CONNECTION OF CABLE LINE IN CONDUCTIVE MEDIUM Russian patent published in 2015 - IPC H01R13/52 

FIELD: electricity.

SUBSTANCE: releasable leak-tight electric connector of wet contact type is intended for electric connection of cable line in conductive medium. The connector consists of lower and upper parts; the upper part consist of a body, bellows with chamber filled with insulating fluid, contact group with required number of contacts, which is connected to a cable line by means of geophysical head and protective housing with pull-back spring and two-piece gripper, at that the two-piece gripper is placed in lower part of the body and cavity of the gripper is filled with insulating fluid. Lower part of the connector consists of the body with groove for two-piece gripper, wherein a block of contact rings is placed and the latter connect with a cable line by means of geophysical head, bellows with chamber filled with insulating fluid, protective housing leak-tight pressed by a spring and a rod with a groove for two-piece gripper. Sealing elements are installed between protective leak-tight housings and bodies of the upper and lower parts of the connector.

EFFECT: improving reliability of both electrical and mechanical leak-tight connection of the line, including connection at dual completion of oil wells.
