Electrical connectors, particularly connectors fluid-tight on immersion in a liquid

Claim 1

An electrical connector, particularly a fluid-tight connector on immersion in a liquid, comprising two elongate connector elements each having respective electrical contacts at a forward end thereof, said connector elements coupleable mechanically with one another, to cause the mechanical and electrical cooperation in pairs of said electrical contacts, at least one of the connector elements comprising an insulating body which is pierced by longitudinal housings shielding the contacts respectively and which is itself retained and shielded, at least in part, in an outer casing, clamping means for clamping the rear end of the connector element to an electrical cable having an outer sheath and joined electrically to the contacts being provided in addition, characterized in that said clamping means comprise: at least one collar gripping the outer sheath of the cable, said collar having at least two radial diametrically or approximately diametrically opposite radial projections, at least two half-clamps having an outer surface and engirdling the rear end of the insulating body and a neighboring zone of the cable, including here the collar gripping the cable, each projection of the collar being engaged in two respective inner recesses of the two half-clamps, said recesses and said collar projections being so shaped and dimensioned that the collar projections are closely surrounded by the recess walls so that the collar and the half-clamps, and consequently also the insulating body, are mutually interlocked axially and in rotation, wherein said half-clamps have respective, mutual abutting supporting edges and, along at least a portion of their mutual supporting edge, the half-clamps have a rim projecting outwardly, and assembly means associated with the two half-clamps to maintain the latter assembled one against the other and said assembly means comprising clips which straddle the half-clamps and which, in a corresponding zone thereof that is situated facing the rims abutting the half-clamps, each clip possesses a channel gripping the two abutted rims of the two half-clamps.
