Definitions

  • the present invention relates to the field of electrical connection, more particularly to electrical connection devices intended to be watertight between an electrical outlet and an electrical appliance comprising an electric cable connection at one end of which electrical connection means are fixed to the power outlet.
  • the prior art proposes sealed electrical connection devices between two means for connecting electric cables, of the respective male / female type placed at the end of the electrical cables that are to be connected, by sealing electrical connection by a sealed engagement of the connecting means, plus precisely the envelope of the plug which fits into the envelope of the socket female, performing during this coupling operation a sealing by contact of the respective envelopes, thus preventing the introduction of liquids into the connection of electrical wires inside the envelopes.
  • connection devices are specific and require a pairing of the plugs and female, which limits the flexibility of use. Indeed, when one wishes connect a standard socket that does not have sealing means to a socket current whose envelope has a sealing system provided for the envelope complementary to a complementary socket, the consequence is that the connection is not more tight. In general, there is no connection device electrical connection making it possible to obtain a watertight connection whatever the means of electrical connection, in particular regardless of the shape of the outer casing of the socket fitted to an electrical appliance, more precisely attached to its electric cable.
  • the present invention makes it possible thanks to a sealed enclosure such as this is defined above, to make the electrical connection at liquid level appropriate socket placed in the enclosure, made with the complementary socket any electrical appliance that does not have sealing equipment specific on its catch.
  • the proposed configuration of the first and second parts of the enclosure allows increased efficiency of the seal, and better hold in the time of this seal.
  • the screw-nut type connection makes it possible to exert a force important and multiplied on the first crossing to settle or perfect the sealing in this zone, and the flange means which are not rotated in rotation by the cover, allow to exercise, via the latter during its rotation, an effort on the traversing without the friction due to the rotation of the cover, thus avoiding wear premature seal.
  • the flange means intended to compress said first crossing to ensure its sealing are associated with said cover by a link having a degree of freedom in rotation.
