Electrical connector assembly comprising an electrical plug and socket suitable for removably collaborating with one another; - said electrical plug comprising at least two concentric annular electrical tracks (11, 12) intended to come respectively to collaborate with electrical contacts (21, 22) of the electrical socket; - magnetic control means (13, 23) comprising at least one first magnet incorporated in the plug and at least one mobile magnetic element, incorporated in the socket to generate a first control force when the plug is placed alongside the socket, the mobile magnetic element being attracted by the first magnet and to position and hold the plug on the socket so that the annular tracks (11, 12) are respectively in contact with the electrical contacts (21, 22) of the socket, - said at least two electrical contacts (21, 22) being mobile, secured to the magnetic element, being able to be displaced between a first position inside the socket and a second position outside said socket to be respectively in direct electrical contact with the electrical tracks (11, 12) of the electrical plug, so that the first control force simultaneously displaces the mobile magnetic element and the electrical contacts (21, 22) between the first position and the second position, - shutter means positioned in front of openings through which the electrical contacts (21, 22) can pass, said shutter means being able to change from a closed position to an open position under the action of the first control force to allow the electrical contacts (21, 22) to switch from the first position to the second, characterized in that the shutter means respectively comprise two shutters, each shutter being linked to a closure spring, the opening of the shutters being provoked by a thrust from the electrical contacts (21, 22) when they are displaced from the first position to the second position onto said shutter means. - said electrical plug comprising at least two concentric annular electrical tracks (11, 12) intended to come respectively to collaborate with electrical contacts (21, 22) of the electrical socket; - magnetic control means (13, 23) comprising at least one first magnet incorporated in the plug and at least one mobile magnetic element, incorporated in the socket to generate a first control force when the plug is placed alongside the socket, the mobile magnetic element being attracted by the first magnet and to position and hold the plug on the socket so that the annular tracks (11, 12) are respectively in contact with the electrical contacts (21, 22) of the socket, - said at least two electrical contacts (21, 22) being mobile, secured to the magnetic element, being able to be displaced between a first position inside the socket and a second position outside said socket to be respectively in direct electrical contact with the electrical tracks (11, 12) of the electrical plug, so that the first control force simultaneously displaces the mobile magnetic element and the electrical contacts (21, 22) between the first position and the second position, - shutter means positioned in front of openings through which the electrical contacts (21, 22) can pass, said shutter means being able to change from a closed position to an open position under the action of the first control force to allow the electrical contacts (21, 22) to switch from the first position to the second,
