A connector for detachable connection of an end region, provided with a ferrule (4), of an optical waveguide (3) to another optical waveguide in a plug-in direction, has a housing (2) with a holding region (21) for guiding the ferrule (4), which is constructed such that the ferrule (4) is guided in an angularly moveable fashion with reference to the plug-in direction. The housing has a stress-relief region (7) for firmly connecting the optical waveguide (3) to the housing (2), in the region between the stress-relief region (7) and the holding region (21) at least one curvature-limiting region (8) being provided for limiting the outward bending of the optical waveguide (3) given an angular displacement of the ferrule (4) with reference to the plug-in direction. Given the suitable design of the curvature-limiting region (8), outward bending of the optical waveguide (3) beyond a maximum permissible curvature is prevented with the aid of the configuration according to the invention.

L'invention concerne un connecteur enfichable pour connecter de façon libérable une zone terminale pourvue d'une ferrule (4) d'un guide d'onde optique (3) à un autre guide d'onde optique, dans un dispositif d'enfichage. Ce connecteur comprend un boîtier (2) comportant une zone de retenue (21) pour guider la ferrule (3), ladite zone étant conçue de sorte que la ferrule (4) soit guidée de façon mobile en formant un angle par rapport au dispositif d'enfichage. Le boîtier présente une zone de décharge de traction (7) servant à relier de façon rigide le guide d'onde optique (3) et le boîtier (2). Dans la région située entre la zone de décharge de traction (7) et la zone de retenue (21), il est prévu au moins une zone de limitation de courbure (8) servant à limiter la pliure, vers l'extérieur, du guide d'onde optique (3) en cas de déplacement angulaire de la ferrule (4) par rapport au dispositif d'enfichage. Lorsque la zone de limitation de courbure (8) est conçue de manière appropriée, la configuration selon l'invention empêche une pliure, vers l'extérieur, du guide d'onde optique (3) au-delà d'une courbure maximale admissible.
