  • Patent number: 5167521
    Abstract: Electrical plug connectors used in humid locations are provided with sealing elements (16, 26) at their cable ends and at their plug ends, which results in an enclosed volume of air in the interior space (27) of the plug connector. If there are fluctuations in temperature and/or pressure in the surrounding space (19), the interior space (27) is at relative overpressure or underpressure; the underpressure situation leads to seepage of water into the plug connector. In accordance with the invention, this is avoided by forming the sealing elements (16,26) of an air-transmissive yet water-repellant material, preferably polytetrafluoroethylene (PTFE), so that they can also serve as pressure equalizing elements. Plug connectors according to the invention are particularly well suited for use in spaces subjected to wide-ranging temperatures and/or to water infiltration resulting from high ambient humidity.
