Abstract
A multi-way, electro-optic connector comprises an optical fiber plug connector 1 and an electro-optic receptacle connector 100. Identical cover members 2 and 3, of the plug connector 1 define divergently curving optical fiber guiding channels 23 of at least a minimum curvature obviating transmission losses. Ferrule assemblies 5, each include an outer ferrule 25 receiving a reinforcing tube 26 and an inner ferrule 27 having slits 27a in optical fiber receiving ends and force-fitted into the reinforcing tube 26 with the core 24 received in a bore 31 of the outer ferrule as a sliding fit. Clamping collars, 9 and 10 are deformed to clamp cable reinforcing fibers 8 by assembly of the cover members 2,3. A one-piece, ganged sleeve member 130 and a retaining member 150 retain transducers 140 with leads trapped in grooves 138a,b and 139 for subsequent insertion in a main receptacle housing 110.
