Connector part of a connector unit

A connector unit for use underwater or in a wet or severe environment, comprising

• a first connector part in form of a male part comprising a conductor pin and a second connector part in form of a female part comprising a current carrying component configured to be in electrical contact with the conductor pin after a mating process of the male part and the female part,
• the female part comprising at least one electrically conductive layer comprising at least one end region being electrically stressed after the mating process, the female part further comprising at least one stress control device for reducing electrical stress at the at least one end region,
• wherein the at least one stress control device comprises a first stress control device comprising a first device conductive component, a first device insulative moulding, and a first device fastening structure in electrical communication with the first device conductive component and with a high voltage part of the connector unit, wherein the first stress control device is mounted in a bore of the female part via the first device fastening structure,
• wherein the first stress control device comprises an annular shape allowing the conductor pin of the male part to be inserted therethrough,
• wherein the first device insulative moulding provides a radially outwardly facing surface which is in physical contact with an insulating sleeve of the female part.
