Abstract
An adhesiveless connector 1 for a fiber optic cable 3 has an alignment ferrule 7 with a tubular passageway 24 for encircling an optical member 3 having a jacket 6 and fiber 2 and a tip 8 with centrally disposed aperture 16 for closely receiving an end of the fiber 2 from the tubular passageway 24. An internal precision alignment surface 15 leads from the tubular passageway 24 to the aperture 16. The ferrule 7 has locking means 10 at its rear end for gripping the jacket 6 of the optical member 3 and a clamping means comprising a collet 48 with compression ring portion 54 for gripping the fiber buffer 4. The compression ring portion 54 is urged radially by the inner surface 23 of the tip 8 to compress against the fiber buffer 4 for alignment of the end of the fiber 2 within the aperture of the ferrule 16.
