Abstract

A plug connector for connecting an attachment cable to a mating plug connector of an electrical appliance in the form of a vacuum cleaner, wherein the plug connector has a contact carrier having plug contacts which are connected or connectable to the attachment cable and which can be brought into an electrical contact position with mating plug contacts of the mating plug connector by a plugging movement along a plug axis, wherein the contact carrier is received, in an axially movable manner with respect to the plug axis, in a plug housing which is mounted rotatably about the plug axis with respect to the contact carrier, wherein rotary form-fit contours are arranged on the plug housing and can be brought into form-fit engagement with mating rotary form-fit contours of the mating plug connector by a rotation movement of the plug housing about the plug axis with respect to the contact carrier, such that the plug connector is secured on the mating plug connector in a tension-resistant manner with respect to the plug axis, and wherein the plug connector has a cable sleeve for the attachment cable.
