ABSTRACT:
An improved connector mechanism having a connector coupling nut of a cylindrical tubular configuration with a bore extending therethrough. In one embodiment, the coupling nut has camming slots which align with bayonet pins on the mating adapter serving to draw the connector inwardly to the adapter upon rotation of the coupling nut. A detent window at the end of each camming slot engages and retains the bayonet pins driven slidingly along the camming slots during rotation. A resilient spring member provides stability between the end of the adapter and the internal bore of the coupling nut at the completion of the coupling operation. Variations of spring arrangements force the cylindrical fiber optic terminus, located axially centered within the coupling sleeve, forward to assure pressured abutment with a like mating terminus located opposite at the other end of the adapter. A cylindrical alignment element in the adapter having an internal bore accepts termini tips slidingly from both sides, radial forces provided by this tip assuring resistance force and stability of location of tips with the alignment bushing. A cable jacket/strength member termination at the rear of the terminus is affixed to the terminus in such manner as to be independent of any influence on the fiber/terminus tip. In another embodiment, the connector has a threaded coupling mechanism. In yet another embodiment the transmission medium may be an electrically conducting metallic wire.
