Abstract
An improved mechanism for drawing the two cylindrical parts of a multi-contact electrical connector together and holding them locked in position employs three rings stacked around one of the two cylindrical parts. In one embodiment, the middle ring is able to rotate and the two outer rings are non-rotatably attached to the cylindrical part on which the rings are mounted. A barrel surrounds the three rings and is arranged to rotate with the middle ring. The barrel has a collar that engages the other cylindrical part of the connector to initially hold the two parts together. The three rings, on their facing surfaces, have sloping cams. The sloping cams are arranged, upon rotation of the middle ring, to cause the middle ring and one of the outer rings to move apart while simultaneously causing the middle ring and the other outer ring to come closer together so that the total height of the three rings remains substantially unchanged.
