Abstract
An anti-rotation lock for a connecting piece of a quick connector which is configured to receive a coupling; comprises a main body having at least one first anti-rotation lock element which is configured and dimensioned to form a projection on the connecting piece, the projection extending in an axial direction with respect to the connecting piece and being configured to interact with a matching recess in the coupling, in order to prevent a rotation of the coupling relative to the connecting piece in a coupled state of the quick connector.
Claims13
:
- An anti-rotation lock, for a connecting piece of a quick connector which is configured to receive a coupling;
- comprising:
- a main body having at least one first anti-rotation lock element which is configured and dimensioned to form a projection on the connecting piece, the projection extending in an axial direction with respect to the connecting piece and being configured to interact with a matching recess in the coupling, in order to prevent a rotation of the coupling relative to the connecting piece in a coupled state of the quick connector;
- wherein the main body having the at least one first anti-rotation lock element is formed as a component which is separate from the connecting piece.
A socket device for a quick connector, wherein the socket device is configured to receive a coupling and is attached to a device for dispensing or receiving liquid or gaseous media in a motor vehicle;
- comprising
- a connecting piece attached to the device;
- and
- an anti-rotation lock, wherein the anti-rotation lock is mounted on the connecting piece after the completion of the device having the connecting piece attached thereto, wherein the anti-rotation lock comprises:
- a main body having at least one first anti-rotation lock element which is configured and dimensioned to form a projection on the connecting piece, the projection extending in an axial direction with respect to the connecting piece and being configured to interact with a matching recess in the coupling, in order to prevent a rotation of the coupling relative to the connecting piece in a coupled state of the quick connector,
- wherein the main body having the at least one first anti-rotation lock element is formed as a component which is separate from the connecting piece;
- and
- wherein the main body has a ring shape with a central axis, which coincides with a central axis of the anti-rotation lock in a state of the anti-rotation lock assembled with the connecting piece.
A method for assembling a socket device for a quick connector, comprising:
- providing a device for dispensing or receiving liquid or gaseous media in a motor vehicle with a connecting piece attached thereto;
- providing an anti-rotation lock,
- attaching the anti-rotation lock to the connecting piece;
- latching the anti-rotation lock with the aid of a latching element formed thereon in a groove at the base of the connecting piece for axially defining the position of the anti-rotation lock on the connecting piece;
- latching the anti-rotation lock with the aid of an index section formed thereon in a corresponding index section which is arranged in a surrounding area of the connecting piece on a device, in order to define the position of the anti-rotation lock in a circumferential direction.
