Connector for optical fibres

Claim 1

A connector for optical fibres, said connector including two groups of three cylindrical support rods all of the same diameter and guide means to keep said two groups of three rods side by side and in contact with each other so as to provide a central passage to house the optical fibres, said passage being delimited by the adjacent side surfaces of the three rods, the improvement wherein said guide means includes a group of at least three bearings which are held coaxially including two end bearings, at least one of said three bearings being sized to and surrounding the two groups of three rods on either side of their plane of contact with very little play and forming a central bearing, said end bearings surrounding each group of three rods with the same or a slightly greater play, said bearings being fitted in housings in a coaxial sleeve, the central bearing being in the plane of symmetry of the sleeve and the end bearings being located at the ends of the sleeve, and wherein said coaxial sleeve consists of two symmetrical end portions having outer ends of each end portion forming a housing for a respective end bearing, and an intermediate sleeve component whose inside bore diameter is larger than that of the bores of the end portions, said intermediate component housing said central bearings.
