Definitions

• the invention relates to a three-phase electrical power connector.
• the three-phase electrical power connector comprising a plug and a base, each of which respectively comprises a housing and treated electrical conductive contacts housed at least partially within the housing and each corresponding to the electrical phase of the electric current transmitted by the connector, wherein each electrical conductive contact is at least partially surrounded by an electrically insulating sheath.
• the invention finds a particularly interesting application in the marine oil rigs or the repair of an electrical connector may require a lot of time.
• each contact is arranged so that, when the plug and the base are connected, the sheaths surrounding the contacts of the same phase each form a closed chamber electrically insulating the contacts of this phase.
• each phase is electrically insulated from the other phase located inside the connector, this insulation being obtained by the chambers formed by the sheaths.
• the ducts are of tabular configuration surrounding each of the electrical conductive contacts.
• the sc io of the sheaths is preferably circular and the wall of each of the sheaths surrounds the contact (the electrically conductive part) at a determined distance, sufficient to prevent an electric arc emitted within one of the phases from reaching and disturbing.
• the at phases for example equals. 0.01 to 5 times the diameter of the contact and preferably equal to 0.3 to 1 times the diameter of the contact ,.
• each of the sheaths is made of an electrical insulating material, for example a dielectric plastic.
• the thickness of each sheath will be determined as a function of the voltage of the electrical current transmitted by the connector, and will advantageously be sufficient so that the wall can not be traversed by an electric arc.
• the repairer of each sheath can be determined according to the distance of the game to the contact so that the wall can not be traversed by a are electric.
• each of the sheaths is at least partially coated internally and / or externally with an electrical shielding layer, for example a metallization layer or a metal braid connected to an electrical mass, which isolates any electrical anomaly of the electromagnetic field on one of the phases likely to affect the other phases.

• the connector can be used in submarine applications and in this case at least one housing of the plug and / or the connector base contains electrical insulating oil (dielectric oil), preferably in a state of overpressure relative to a surrounding environment, marine in particular (a few bars), so as to prevent any entry of water into the connector.

• the fact of putting the connector under pressure, compared to the marine environment makes it possible to evacuate oil from the housing towards the outside (in weak quantity) and to prevent the tendency of migration from the external environment inwards to the risk of polluting the oil.

• the sheath of a male contact does not cover the end of the male contact intended to be inserted inside the female contact and the end portion of the sheath (lace side connection) the female contact which seals with the external medium protrudes sufficiently from the female contact to, in the connected position, completely cover the end of the male contact not covered by the sheath.
• the sheaths of the containers may be in several parts, or at least two parts which overlap each other.
• the connector comprises sealing means for protecting the connector of an external fluid, for example water, sea.
• the sealing means may consist of the sheath of the conductive cables connected to the contacts, this sheath may be coated with a layer of metallisatiom which reinforces the sealing of the sheath with seawater, in particular at high pressures sub- marine and thus protects the connector of a water inlet between the insulating sheath and the contact.
