Abstract:
1. Electrical connection device comprising two mating connection elements ( 1 , 2 ), one ( 2 ) of which comprises an outer casing ( 12 ), and each of which are provided with electrical contacts ( 3 ; 4 a , 4 b ) intended to cooperate with each other in a connection position, after the coupling of said elements ( 1 , 2 ) has been obtained by a first relative translational motion, followed by rotation and a second translational motion, the connection elements being in an intermediate rest position at the end of said rotation, wherein said elements are temporarily held together, without the contacts being connected, whereas the connection is established between the contacts of the two connection elements ( 1 , 2 ) only at the end of the second translational motion, which determines said connection position, characterised in that the connection element ( 1 ) mated with the element ( 2 ) comprising the outer casing ( 12 ) is provided with a flexible tubular outer seal ( 13 ) fastened at one end to said element ( 1 ) and provided with at least one annular front stop surface ( 14 ), which is intended to cooperate by contact with a mating surface ( 15 ) provided on said casing ( 12 ) of the other element ( 2 ), and which comprises a rigid or semi-rigid ring ( 11 ) provided with means for ensuring translational guiding during coupling of the connection elements ( 1 , 2 ), whereby a leak-tight seal is ensured between said connection elements from at least the intermediate rest position thereof to the connection position thereof, due to the cooperation of the annular front stop surface ( 14 ) of the seal ( 13 ) and the mating surface ( 15 ) of the casing ( 12 ), said seal ( 13 ) being further subjected to pleating in the connection position, due to the second relative translational motion of the connection elements, whereas said mating surfaces ( 14 , 15 ) are designed to enable sliding relative to one another during the rotational motion of said connection elements ( 1 , 2 ).
