Definitions
- the present invention relates to an underwater connection structure such as a junction box or a connector, comprising, in a sealed enclosure, electrical and / or optical elements to be connected, said enclosure being at least partially filled with a fluid dielectric.
- junction boxes and connectors currently used for underwater applications are sealed by often redundant seal systems, and filled with a generally dielectric fluid, which allows the junction box or connector to be balanced with the external pressure thanks to a deformable membrane constituting a part of the wall of the junction box or the connector.
- the seals may have sealing defects over time. In this case, the fluid used, which is often less dense than water, is gradually replaced by the surrounding water, which leads to a loss of electrical insulation.
- the purpose of the present invention is to provide subaquatic connection structures of the type indicated by simplifying the sealing means to be implemented, while ensuring electrical isolation of the electrical and / or optical elements to be connected and a good seal against -vis the surrounding water.
- the underwater connection structure according to the invention is characterized essentially by the fact that the dielectric fluid introduced into the chamber is chosen so as to be immiscible with water, insoluble in water and have a dynamic viscosity which increases strongly between a first low value, at a first temperature higher than the ambient temperature in the air at which the dielectric fluid is introduced into the chamber, and a second high dynamic viscosity value, at a second temperature, lower than said first temperature, to which the connection structure is subjected once submerged to a depth of use.
- the dielectric fluid is preferably chosen so as to have good adhesion to the constituent materials of the electrical and optical cable sheaths, which, they can have a low adhesion (made of polytetrafluoroethylene for example). This feature prevents water that could have entered the connection structure from moving along the cable sheaths and reaching a stripped portion.
- the dielectric fluid then constitutes a highly viscous gelled mass sealingly coating the electrical and / or optical elements inside the enclosure.
- the first dynamic viscosity value is a few tens of mm 2 / s, in particular of the order of 30 mm 2 / s and the second dynamic viscosity value is several thousand mm 2 / s, particularly more of 15000 mm 2 / s.
- the first temperature is greater than 30 ° C. and preferably of the order of 55 ° C.
- the second temperature is less than 25 ° C., in particular of the order of 20 ° C.
- At least one wall of the enclosure is formed of a flexible membrane and waterproof, for example Nitrile rubber or silicone.
- dielectric fluids that can be used according to the invention, mention may be made of the Casing Filler E-800-HB product marketed by Hydro Safe Oil Company, Inc., and the Union Gard 160 product marketed by Union Gard. , division of Dome Services LLC.
- FIG. 1 schematically illustrates an underwater connection structure in the form of a junction box
- Figure 2 schematically illustrates an underwater connection structure in the form of a connector.
- the underwater junction box illustrated in Figure 1, comprises a sealed enclosure generally designated 1 and a part of the wall is constituted by a flexible flexible membrane 2. There are illustrated three electrical cables 3 and / or optical whose electrical conductors or optical fibers 4 are exposed for their connection to the inside of the junction box.
- FIG. 1 also shows two filling orifices 5 sealingly closed and through which a dielectric fluid 6 filling the enclosure is introduced, which may for example be the Casing Filler E-800-HB mentioned previously introduced in FIG. surface at a temperature substantially greater than the atmospheric temperature, for example of the order of 55 ° C. It is understood that because of the presence of the dielectric fluid 6 which constitutes a highly viscous mass at the depth of use, a complete coating of the exposed parts of the cables is carried out inside the junction box, this mass constituting a barrier effective sealing, even in case of rupture of the outer wall of the enclosure or permeation of water through this wall.
- a dielectric fluid 6 filling the enclosure
- the Casing Filler E-800-HB mentioned previously introduced in FIG. surface at a temperature substantially greater than the atmospheric temperature, for example of the order of 55 ° C.
- FIG. 2 shows a cable 3 'whose exposed electrical conductors and / or optical fibers 4' are surrounded by the dielectric fluid 6 '.
- FIG. 2 also shows, at the ends of the conductors and / or optical fibers 4 ', contacts 7' and connectors 8 '.
