The electrical connector with threaded interlock comprises a male electrical plug having an plug body and male electrical terminals, and a female electrical plug having an plug body and female electrical terminals. One of the plugs is externally threaded with the threads extending along the body of the plug in a direction away from the electrical terminals. The other of the plugs has a cylindrical collar member slidably and rotatably mounted on it. The collar member is internally threaded such that the internal threads may cooperate with the external threads on the externally threaded plug. The collar member is moveable between a retracted position with the collar member clear of the electrical terminals, and an extended position such that the internal threads of the collar member can be moved into contact with the external threads for engagement with each other thereby securing the male and female plugs together. Since the external threaded portion extends in a direction away from the electrical terminals, and the collar member is retractable to a position clear of electrical terminals, the connector does not interfere with the electrical terminals of either the male or female plug. This allows a plug having either the external thread or the collar member to be used with a standard plug on a power cord, or with a standard wall outlet.
