<p>The invention proposes a quick connection which has utility in a wide field, for instance, for connecting fluid lines, electric cables, etc., and comprises an inserted tubular end portion, which is formed near its extreme end with concave recesses serving as detent means, and which is provided with a radially acting locking collar. The second tubular end portion comprises a socket, which contains an inserted locking ring, which has detent fingers, which releasably interlock with the concave recesses of the inserted tubular end portion and are provided on their back side with reversely foldable, thin webs which bear on the inside surface of the socket. Such quick coupling can be resiliently interlocked simply in that the tubular end portions are urged into each other, and can be unlocked only by an angular movement. The coupling is particularly adapted to be connected and disconnected by industrial robots in automated production sequences. The coupling transmits longitudinal forces and is radially locked. It can easily be disconnected and can be mounted quickly and is tight and prevents an ingress of dirt. The components of the coupling consisting of the tubular end portions and the locking ring preferably consist of plastics which are most suitable for the field in which the quick connector is to be used. Such plastics include, e.g., polyamides, PVC, polyethersulfone, polyetherketone or the like. The components may be made of rigid or flexible materials.</p> |
