Cable fixing means
The invention relates to a cable retainer ( 1 ) for mechanically retaining a cable ( 10 ) on a cable outlet, comprising a cable outlet connection piece ( 2 ), a sealing element ( 3 ) and a pressure element ( 4 ), wherein the pressure element ( 3 ) can be screwed onto the cable outlet connection piece ( 2 ) using a thread ( 2.1, 3.1 ) and in this way squeezes the sealing element ( 3 ) together between the cable output connector ( 2 ) and the pressure element ( 4 ). By means of detents ( 4.2 ) on the pressure element ( 4 ) and detents ( 2.2 ) on the cable outlet connection piece ( 2 ) that cooperates therewith, a release of the threads ( 2.1, 3.1 ) screwed together is prevented.
1. A cable retainer ( 1 ) for mechanically fixing a cable to a cable outlet,
comprising a cable outlet connection piece ( 2 ), a sealing element ( 3 ) and a pressure element ( 4 ),
wherein the cable outlet connection piece ( 2 ) has a first thread ( 2 . 1 ), the pressure element ( 3 ) has a second thread ( 3 . 1 ) and the two threads ( 2 . 1 , 3 . 1 ) cooperate in such a way that the pressure element ( 4 ) can be screwed onto the cable outlet connection piece ( 2 ),
wherein the sealing element ( 3 ) is provided between the cable outlet connection piece ( 2 ) and the pressure element ( 4 ), and wherein the components ( 2 , 3 , 4 ) of the cable retainer ( 1 ) have a through-opening ( 5 ) used for receiving a cable to be retained,
wherein the pressure element ( 4 ) has detents ( 4 . 2 ) and the cable outlet connection piece ( 2 ) has detents ( 2 . 2 ),
wherein the detents ( 2 . 2 , 4 . 2 ) engage with each other in such a way that a release of the threads ( 2 . 1 , 3 . 1 ) screwed together is prevented,
wherein the detents ( 2 . 2 , 4 . 2 ) are each formed by peripheral latching teeth, wherein the detents ( 2 . 2 ) are formed counter-currently to the detents ( 4 . 2 ),
wherein the detents ( 2 . 2 ) are moulded onto an additional latching element ( 6 ) that can be placed on the cable outlet connection piece ( 2 ) in a non-rotatable manner,
characterised in that
the latching element ( 6 ) has at least one predetermined breaking point and in that, by screwing off the pressure elements ( 4 ) against the detents ( 2 . 2 , 4 . 2 ), the latching element ( 6 ) can be broken at the predetermined breaking point.
2. The cable retainer according to claim 1 ,
characterised in that
the latching element ( 6 ) is formed as a ring and is retained in a non-rotatable manner on at least one flattening ( 2 . 3 ) on the cable outlet, connection piece ( 2 ) by means of at least one corresponding moulding ( 6 . 3 ) on the latching element ( 6 ).
3. The cable retainer according to claim 1 ,
characterised in that
a spring element ( 7 ) is provided which applies a spring force on the latching element ( 6 ) against the detents ( 2 . 2 , 4 . 2 ).
4. The cable retainer according to claim 3 ,
characterised in that
the spring element ( 7 ) is an elastically deformable plastic ring.
5. The cable retainer according to claim 1 ,
characterised in that
the detents ( 2 . 2 , 4 . 2 ) are formed in an axial direction of the threads ( 2 . 1 , 4 . 1 ).
6. The cable retainer according to claim 1 ,
characterised in that
the detents ( 2 . 2 , 4 . 2 ) are formed in a radial direction relative to the threads ( 2 . 1 , 4 . 1 ).
