Connector with self-centering elements for optical conductors

Claim 1

A connector for optical conductors, comprising: a casing formed by two opposite bodies and complementary fixing means for assembly of one of the opposite bodies to the other of the opposite bodies with axial pressure, each said body receiving a cylindrical member comprising a shoulder portion and a barrel portion, said cylindrical member being retained by said shoulder portion and disposed with said barrel portion directed towards the corresponding barrel portion of the cylindrical member mounted in the opposite body, each of said cylindrical members being floatingly mounted with respect to its corresponding body, each cylindrical member further being adapted to receive an end of an optical fiber within a central bore at the end of the barrel portion in such a manner that the conductor is fixed therein with its end being flat and located in the plane of the end of the barrel portion of the cylindrical member, having at least two annular grooves in the barrel portion and longitudinally spaced along the length of the latter, the bases of said grooves being concentric with the said central bore and said grooves containing toroidal joint means for the floatingly mounting of said cylindrical members with respect to the corresponding body, and the connector further comprising a coupling member floatingly mounted with respect to both said bodies and into which the barrel portions of the cylindrical members extend opposite to one another, the arrangement being such that said toroidal joint means, when under compression, allow self-centering of the cylindrical members within the said coupling member when the latter are engaged against one another under the action of said complementary fixing means.
