Receiving part of a coupling for a fluid line

摘要

An electric resonant circuit is provided in a receiving part of a coupling for a fluid line, the resonant circuit interacting with a tuning device in a contactless manner. In an intermediate position of an insert part, which differs from a closed position, the resonant circuit has a resonant frequency that differs from the characteristic closure frequency, and in the closed position the resonant circuit has the characteristic closure frequency. The tuning device acts on the inductance of the electric resonant circuit. An acting part is provided that mechanically acts on the coil when the insert part is inserted into the receiving part such that the shape of the coil in the closed position differs from the shape of the coil in the intermediate position.

1. A coupling for a fluid line comprising:
a plug-in part; a receiving part adapted to receive said plug-in part and lock said plug-in part in a closed position, said receiving part comprising an acting part and a tuning device; an electric resonant circuit connected to said receiving part, said electric resonant circuit having an inductance and comprising a coil and adapted to resonate at a frequency corresponding to a characteristic closure frequency when said plug-in part is in said closed position and exposed to electromagnetic energy, wherein said electric resonant circuit is permanently closed and said tuning device interacts contactlessly with said resonant circuit and mechanically with said plug-in part and acts on the inductance of the electric resonant circuit, such that:
when said plug-in part is inserted into said receiving part, said acting part acts mechanically on said coil such that the shape of said coil in said closed position differs from the shape of the coil in an intermediate position, andwhen said plug-in part is in said intermediate position, said resonant circuit has a resonant frequency that differs from said characteristic closure frequency, and in said closed position has said characteristic closure frequency.
