Abstract
Abstract A pressurized water-proof connection for connecting an electrical cable to a housing of an electrical sensor is disclosed. An intermediate housing for connecting the electrical sensor contains a coupling piece electrically connected to the sensor with contact elements and a collar having an internal thread and with coupling sleeves directed in the axial direction of said collar. A plug with contact elements connected to electrical wires of an electrical cable is insertable through the collar. A closure sleeve has a thread portion for the internal thread of the collar and also a thread for a screw-type cable fitting for the electrical cable.
