Patent attributes
A circular rapid-joint connector, which includes a sliding bush with multiple extension sections and recession areas provided on an end thereof; an elastic element provided on the inner edge of the sliding bush; a holding unit joined with the sliding bush movably, the outer edge thereof having a limiting unit capable of limiting each of the extension sections; and a connector plug penetrating into the sliding bush and joined with the holding unit. In assembling, direct docking with a connection socket by the connector plug is available for the connection socket to push away the sliding bush. After the connection socket and the connector plug are snap-fitting, the sliding bush is pushed back by the elastic element automatically, such that the sliding bush is locked in the outer edge of the connection socket to complete the operation of assemblage.
