Patent ID: 8636527

Claim:
An electrical connection assembly comprising, a female element which includes at least one electrical contact and a male element for inserting into the female element, the male element including a plug that extends along a longitudinal axis (A 4 ), a sleeve that surrounds the plug and that is movable relative to the plug, and at least one electrical contact that is carried by the plug and that is electrically engageable with the at least one electrical contact carried by the female element, an exterior connection surface of the at least one electrical contact of the male element being covered by the sleeve in a first axial position of the sleeve relative to the plug and uncovered in a second axial position of the sleeve relative to the plug, an external radial surface of the sleeve including at least two cylindrical stages each having a circular cross section and having diameters of which are smaller relative to one another in a direction toward a free end of the male element, and the female element including a body having an internal radial surface which includes at least two stages having diameters which are larger in a direction toward a mouth of the female element, and wherein external surfaces of the at least two stages of the sleeve are complementary to external surfaces of the at least two stages of the internal surface of the body of the female element, the at least two stages of the sleeve having respectively substantially the same diameters as the at least two stages of the body of the female element such that when the sleeve is fully inserted in the female element a stage of larger diameter of the male element is engaged in a stage of larger diameter of the female element and a stage of smaller diameter of the male element is engaged in a stage of smaller diameter of the female element.
