The invention also relates to a connection system for a propeller-driven submarine vehicle with a submarine cable and such a protective housing. The invention further relates to the use of a protective housing for a propeller of a submarine vehicle for receiving a strain relief connection for a connecting cable. The invention enables low-cost communication between a propeller-driven submarine vehicle and a support platform by means of a connecting cable which is hydrodynamically streamlined and ensures strain-relief for the connecting cable. The connecting cable is fixed to the periphery of the protective housing, outside the working space of the propeller located on a propeller axis, and a strain-relief cable-holding fixture is arranged for a connecting cable on the submarine vehicle. ## Claims ### Claim 1 A protective housing for a propeller of a submarine vehicle, said housing comprising, a strain-relief cable-holding fixture for a connecting cable of the submarine vehicle, the strain-relief cable-holding fixture arranged on the outside periphery of a protective housing surrounding a working space of a propeller about a propeller axis. ### Claim 2 (depends on 1) The protective housing according to claim 1, wherein the cable-holding fixture comprises a drum-shaped housing portion of the protective housing, a periphery of the drum-shaped housing designed to accommodate at least one circumferential winding made by the connecting cable. ### Claim 3 (depends on 2) The protective housing according to claim 2, wherein the cable-holding fixture comprises the drum-shaped housing portion that at least partially axially overlaps an axial clamp band that is secured to the protective housing by a clamping device. ### Claim 4 (depends on 3) The protective housing according to claim 3, wherein the clamping device in the protective casing comprises threaded fastening screws. ### Claim 5 (depends on 4) The protective housing according to claim 4, wherein the periphery of the protective housing comprises a rod-shaped cable rod that is substantially parallel to the propeller shaft and located on the protective housing. ### Claim 6 (depends on 5) The protective housing according to claim 5, wherein the cable rod is flexurally elastic. ### Claim 7 (depends on 6) The protective housing according to claim 6, wherein the cable rod is surrounded in sections by a protective sleeve forming an intermediate space for the insertion of a connecting cable, wherein the cable rod and the protective sleeve form a strain relief. ### Claim 8 (depends on 7) The protective housing according to claim 7, wherein the protective sleeve is formed as a spiral tube. ### Claim 9 (depends on 8) The protective housing according to one of claim 8, wherein the protective sleeve is elastic. ### Claim 10 (depends on 9) The protective housing according to claim 9, wherein the protective sleeve extends beyond a free end of the cable rod. ### Claim 11 (depends on 5) The protective housing according to claim 5, wherein axial struts are located on the protective housing that are connected to an adapter housing located along the propeller shaft wherein at least one of the struts has a cable guide. ### Claim 12 A connection system for a propeller driven submarine vehicle, said connecting system comprising: a connecting cable of the submarine vehicle; and a protective housing for a propeller of a submarine vehicle, said housing comprising, a strain-relief cable-holding fixture for the connecting cable, the strain-relief cable-holding fixture arranged on the outside periphery of a protective housing surrounding a working space of a propeller about a propeller axis. ### Claim 13 (depends on 12) The system according to claim 12, wherein the connecting cable is wound on a drum-shaped portion of the protective housing, said windings of the connecting cable are clamped by means of a rotating axial clamp band on the drum-shaped portion. ### Claim 14 (depends on 13) The system according to claim 13, wherein a periphery of the protective housing comprises a rod-shaped cable rod that is substantially parallel to a propeller shaft of the submarine vehicle and located on the protective housing, the cable rod being surrounded in sections by a protective sleeve forming an intermediate space for the insertion of the connecting cable, wherein the cable rod and the protective sleeve form a strain relief, and wherein the connecting cable between the cable rod and the protective sleeve is led out and held radially. ### Claim 15 A method for providing a strain relief connection for a connecting cable of a submarine vehicle, said method comprising using of a protective housing for a propeller of the submarine vehicle for providing the strain relief connection for the connecting cable at the periphery of the protective housing.
