Plug connection for high-frequency-based field devices

A high-frequency-based field device for determining a process variable of a medium in a container, comprising:

• at least one transmitting and/or receiving antenna which can be attached to the container in order to transmit the high-frequency signal toward the medium, and/or to receive the high-frequency signal after interacting with the medium,
• a device neck which can be arranged on the container in order to contact the at least one antenna,
• an enclosure which resiliently encloses at least one plug in such a way that said plug(s) is/are movable radially to the plugging axis thereof, wherein the enclosure is inserted in the device neck in such a way that the at least one plug is in each case contacted to the at least one antenna,
• a high-frequency module comprising
• a circuit board substrate on which at least one socket corresponding to the plug is arranged, and
• an electronic unit arranged thereon, which is designed to generate the high-frequency signal to be coupled, and to determine the process variable on the basis of the received high-frequency signal, wherein the electronic unit is connected to the at least one socket for this purpose, and
• wherein the circuit board substrate can be fastened to the enclosure in such a way that the at least one plug is inserted into the at least one socket.
