Patent ID: 7167626

Claim:
Assembly comprising a clamping device ( 1 ) and a fiber ( 2 ) held by said device ( 1 ) and comprising a rigid and brittle core ( 24 ) surrounded by a mechanically deformable cladding ( 22 ), said clamping device being adapted to resist a tension force having a value exceeding 5 N exerted along a longitudinal axis of said fiber ( 2 ), said clamping device ( 1 ) comprising several jaws ( 4 ) distributed around a main axis ( 6 ) of this device ( 1 ) and occupying a clamped position, each jaw ( 4 ) comprising an inner surface ( 14 , 114 ) composed of a central portion ( 16 , 116 ) and two end portions ( 18 , 20 , 118 , 120 ), said end portions ( 18 , 20 , 118 , 120 ) being made so as to prolong the central portion ( 16 , 116 ) by gradually moving away from the main axis ( 6 ) of said device ( 1 ), wherein a section of the inner surfaces ( 14 , 114 ) on any plane perpendicular to the main axis ( 6 ) of the device ( 1 ) is a closed line, and wherein only part of each end portion ( 18 , 20 , 118 , 120 ) is in contact with the mechanically deformable cladding ( 22 ) of the fiber ( 2 ).
