Abstract: A three-phase electric power connector (1), comprising a plug (5) and a socket (3), which each comprise respectively a casing (13, 11) and three electrically conductive contacts (9, 7) housed at least in part inside the casing (13, 11) and each corresponding to an electric phase of the electric current transmitted by the connector (1), in which each of the three electrically conductive contacts (9, 7) is surrounded at least in part by an electrically insulating sheath.

Abstract: A plug-in fiber-optic connector (5) for use in a fluid medium, characterized in that the rear tubular portion (21) of the plug is slidingly urged into the body portion (7) first to compress the plug piston chamber (17) then to enable the optical fluid (19) to be discharged at the end of the centring portion (13) and the front portion (9) of the plug, whereby the front end of the optical fiber (5) is dried and cleared of fluid and foreign particles, whereas the centring portion (55) of the base is driven back by the pressure exerted by the plug in such a way that the end of the optical fiber (5) thereof extending outwards into the centring portion (13) of the plug, in alignment with the fiber (5) of the plug (3), is similarly dried by the compressive effect of the piston chamber (59) thereof.
