Connection of a micro-tube to a structure

Abstract

The recess ( 12 ) between the main connecting part ( 8 ) and a collar ( 9 ) contains a toroidal or otherwise shaped sealing ring or joint ( 3 ) and the end of a tube ( 1 ) incorporating an outer flange ( 2 ), whose thickness becomes zero at the crushing bulge ( 4 ) of the sealing ring ( 3 ). An excellent seal is ensured at this location, even for pressurized fluids, and the assembly can easily be dismantled.

1 . Connection of a micro-tube ( 1 ) to a structure ( 8 ), characterized in that it comprises an elastic, cambered joint ( 3 ) surrounding the micro-tube, a flange ( 2 ) fashioned around the micro-tube tapering out of the micro-tube and extending up to a bulging circumference ( 4 ) of the joint, and a collar ( 9 ) on the structure, joined to such structure whilst forming a recess ( 12 ,  14 ,  15 ) in which the joint is held between the faces ( 6 ,  7 ) of the recess on which it bears, the flange bearing on one of said faces.  
     
     
         2 . Connection according to  claim 1 , characterized in that the collar and the structure are pressed towards one another with the aid of a linking means.  
     
     
         3 . Connection according to  claim 1 , characterized in that the flange ( 2 ) is produced in one piece with the micro-tube ( 1 ).  
     
     
         4 . Connection according to  claim 1 , characterized in that the recess ( 14 ,  15 ) is designed so as to support a periphery of the joint ( 3 ).  
     
     
         5 . Connection according to  claim 1 , characterized in that the recess ( 12 ) includes several micro-tubes ( 1 ).
