A plug assembly with strain relief includes a housing and a clamping basket which has radially movable clamping fingers. The clamping basket defines an axis and is constructed to allow insertion of a cable into the housing in a direction of the axis. A rotary sleeve is supported on the housing for rotation but substantially fixed in an axial position with respect to the housing. The rotary sleeve is hereby configured to move an element (e.g. the clamping basket itself, or a pinch ring) in the axial direction, when rotated, to thereby modify a radial position of the clamping fingers.

Plug assembly with strain relief

The socket has a housing, an outer sleeve on the housing centered on an axis and having an axially extending and radially inwardly open groove. A latching element in the housing in axial alignment with the groove is displaceable axially relative to the outer sleeve. A spring or other biasing unit is braced between the latching element and the housing for urging the latching element into an outer position and a mechanical coupling between the latching element and the switch prevents a switch on the housing the switch from moving from its the position to its on position except when the element is in an inner position. A nonmatching plug has a body formed with a radially outwardly open recess and respective contacts in the body are engageable with contacts of the outer sleeve. A tubular adapter body is fittable over the plug body and inside the outer sleeve in an inserted position with the plug contacts engaging the socket contacts. A radially outwardly projecting bump on the tubular body engages the latch element to hold the latching element in the inner position in the inserted position, and a retaining element on the outer sleeve projects radially inward into the recess of the plug body and bears radially outward against the outer sleeve only in the inserted position so that in the inserted position the bump holds the latching element in the inner position and the retaining element locks the adapter and plug in the outer sleeve.
