Optical fibre plug connector with double coupler of two opposite, axial through coupling sockets

摘要

Each coupling socket (1',1'') has a tubular housing (3) and a plug part (2,2') i.e. a plug at front end of optical fibre, or a plug protective cap, both fitted with a tubular coupling housing (4) for sliding or inserting on or into socket housing. Each plug part is fitted with a peripheral lip (8) on coupling housing in cross-sectional plane of plug part. It extends radially either in coupling housing towards longitudinal axis of connector or outside the housing outwards from the axis.
