Sensor housing

Abstract

A sensor has a corpus ( 1 ) comprising an insert opening ( 10 ) through which a sensor element ( 22 ) can be inserted in the corpus ( 1 ), and a cable opening for passing through a supply and/or signal line ( 30, 48 ) of the sensor element ( 22 ), and a cover ( 31 ) closing the insert opening ( 10 ), The cover ( 31 ) comprises an interlock opening ( 42 ) aligned with the cable opening. The supply and/or signal line ( 30, 48 ) comprises a bushing element ( 44 ) which penetrates the cable opening of the corpus ( 1 ) and the interlock opening ( 42 ) of the cover ( 31 ).

       4 . Sensor housing according to  claim 1 , characterized in that at least one pin interlocks an edge—facing the interlock opening ( 42 )—of the cover ( 31 ) on the corpus ( 1 ). 
   
   
       5 . Sensor housing according to  claim 1 , characterized in that the length of a section ( 30 ,  48 ) of the supply and/or signal line—connecting the sensor element ( 22 ) with the bushing element ( 44 )—is dimensioned to be able to pull out the bushing element ( 44 ) from the cable opening without interrupting the supply and/or signal line. 
   
   
       6 . Sensor housing according to  claim 5 , characterized in that the section ( 30 ,  48 ) comprises at least one flexible strip conductor film ( 30 ;  48 ). 
   
   
       7 . Sensor housing according to  claim 6 , characterized in that a flexible strip conductor film ( 30 ) preassembled on the sensor element ( 22 ) and a flexible strip conductor film ( 48 ) preassembled on the bushing element ( 44 ) are connected with each other in a conductive manner. 
   
   
       8 . Sensor housing according to  claim 1 , characterized in that the cable opening ( 42 ) is formed by a tube section ( 9 ) projecting from a basic body ( 2 ) of the corpus ( 1 ). 
   
   
       9 . Sensor housing according to  claim 1 , characterized in that a signal passage window is arranged in the corpus ( 1 ). 
   
   
       10 . Sensor housing according to  claim 9 , characterized in that the signal passage window is formed in a tube section ( 4 ) projecting from a basic body ( 2 ) of the corpus ( 1 ). 
   
   
       11 . Sensor housing according to  claim 8 , characterized in that the tube section ( 9 ;  4 ) comprises an outside thread. 
   
   
       12 . Sensor housing according to  claim 11 , characterized in that the outside thread is interrupted by a facet ( 15 - 20 ) in at least one place of the circumference of the tube section ( 9 ;  4 ). 
   
   
       13 . Sensor housing according to  claim 12 , characterized in that the facet ( 15 ;  17 ;  19 ;  20 ) intersects a core of the outside thread. 
   
   
       14 . Sensor housing according to  claim 12 , characterized in that the outside thread is interrupted by recessed facets ( 15 - 20 ) in at least two places diametrically opposed to each other. 
   
   
       15 . Sensor housing according to  claim 1 , characterized in that the corpus ( 1 ) is formed of metal, in particular of metallic glass. 
   
   
       16 . Sensor housing according to  claim 15 , characterized in that the metallic glass is an alloy on the basis of titanium and zirconium.
