Abstract
Abstract A fiber optic connector, especially for multiplecore fiber optic cables, in which a ferrule (2), mounted in a ferrule insert (3), and adapted to receive the optical fiber (P), is provided in a plug (A, B). An adaptor (C) is provided for receiving the plug, and includes a holding sleeve (11) which is retained in an insert (10). A split sleeve (12) is mounted in the holding sleeve (11) for receiving the ferrule (2). A terminal part (11 b) of the holding sleeve protrudes from the surface of the insert (10) and is snugly received in an insertion recess (14) provided at the forward end of the ferrule insert (10). The terminal part (11b) enters recess (14) after the ferrule (2) has entered the split sleeve (12) at the time of connection of the plug and adaptor.
