| 摘要 |
The invention relates to a device for pair-wise coupling the ends of two groups of optical fibres which are retained by means of clamping devices on respective slides which are displaceable essentially in the longitudinal direction of the optical fibres so that the end faces of one group of optical fibres can be positioned against the end faces of the other group of optical fibres; the device comprises an alignment block which is arranged between the slide and which comprises guide grooves for the alignment of the individual optical fibres in which the ends of the optical fibres, inserted in associated fan-out combs, are arranged and retained by pressure members which exert different forces. A high positioning accuracy is simply obtained in that for each group of optical fibres there is provided a pressure member (18, 19) which exerts a weight-dependent pressure on the optical fibres via a contact member (25, 26), on each pressure member there being provided a magnetic armature (23, 24) which is situated within the range of influence of a permanent magnet (27) which is displaceable, essentially against the force of gravity, towards the magnetic armatures ( 23, 24) of the pressure members (18, 19), thus increasing said weight-dependent pressure.
