Title (EN) DEVICE FOR FIXING A RIGID AND BRITTLE FIBER COMPRISING A MECHANICALLY DEFORMABLE CLADDING AND LIABLE TO BE SUBJECTED TO AT LEAST ONE MECHANICAL STRESS
(FR) DISPOSITIF DE FIXATION D'UNE FIBRE RIGIDE ET FRAGILE COMPRENANT UNE GAINE MECANIQUEMENT DEFORMABLE ET SUSCEPTIBLE D'ETRE SOUMISE A AU MOINS UNE CONTRAINTE MECANIQUE
Abstract: front page image
(EN)The invention concerns a device for fixing (1) a fiber (2) comprising a rigid and brittle core (24) enclosed in a mechanically deformable cladding (22), and liable to be subjected to at least one mechanical stress. The invention is characterized in that the fixing device comprises concentric jaws (4) including an inner surface (14) consisting of a central portion (16) and two end portions (18, 20), the end portions being produced so as to extend the central portion by being gradually spaced apart from the main axis of the device, and including each at least one part in contact with the mechanically deformable cladding when the jaw is in clamping position. The invention is useful for fixing a fiber optic and any fiber optic sensor, in particular with Bragg gratings.
(FR)L'invention concerne un dispositif de fixation (1) d'une fibre (2) comprenant un coeur rigide et fragile (24) entouré d'une gaine mécaniquement déformable (22), et susceptible d'être soumise à au moins une contrainte mécanique. Selon l'invention, le dispositif de fixation comporte des mors (4) concentriques comprenant une surface intérieure (14) constituée d'une portion centrale (16) et de deux portions d'extrémité (18,20), les portions d'extrémité étant réalisées de manière à prolonger la portion centrale en s'écartant progressivement de l'axe principal du dispositif, et comportant chacune au moins une partie en contact avec la gaine mécaniquement déformable lorsque le mors occupe une position de serrage. Application à la fixation d'une fibre optique et à tout capteur à fibre optique, notemment à réseaux de Bragg.
