Patent ID: 8622624

Claim:
An optical plug connection for optical waveguides, comprising a plug and a socket, wherein the plug comprises a lens, wherein the socket is disconnectable from the plug and comprises a centering collar which is locked in a predetermined position on the socket, wherein the socket further comprises a spring ring fastened on the centering collar that fixes the plug in the socket and wherein the plug has at least one plane, smoothed contact face aligned relative to a propagation direction of a light beam exiting or entering the plug, the contact face to rest on at least one corresponding plane, smoothed mating contact face of the socket aligned relative to the propagation direction of the light beam, with the light beam perpendicularly intersecting a plane in which the at least one contact face and the at least one mating contact face are located, wherein, when the plug is inserted in the socket, a frictional connection between the plug and the socket is achieved by rotational movement, thereby permitting the plug connection to be disconnected and joined again without readjustment.
