Abstract:
1. An optical fibre connector sub-assembly for an optical fibre connector, comprising an optical fibre, a cylindrical ferrule, a ferrule holder, a spring biasing means, and a ferrule holder carrier, wherein: the optical fibre is held within the ferrule along an axis of the ferrule, the optical fibre being terminated at an end face of the ferrule; the ferrule is held by the ferrule holder; the ferrule holder is engaged within a receiving portion of the ferrule holder carrier, said holder and carrier being relatively moveable with respect to each other along the ferrule axis between limits defined by an interaction between the ferrule holder carrier and the ferrule holder, a portion of the ferrule leading to said end face of the ferrule projecting along the ferrule axis away from the ferrule holder carrier; the spring biasing means is provided between the ferrule holder and the ferrule holder carrier so that the projecting portion of the ferrule is spring biased along the ferrule axis away from the ferrule holder carrier; the ferrule holder includes a base in which the ferrule is seated; the ferrule holder base has a plurality of crenellations that extend circumferentially around the ferrule, the ferrule holder carrier having at least two separate arms that extend in an axial direction through the crenellations towards the ferrule, said arms including a movement limitation feature that interacts with the ferrule holder base to limit the relative movement of the ferrule holder and the ferrule holder carrier along one direction of movement along the ferrule axis.
