Abstract

A FC-type optical fiber cable connector'"'"'s adaptor, which includes a front casing, which has an externally threaded tubular outer coupling flange and a tubular inner coupling flange concentrically disposed around a center hole thereof for coupling the ferrule of a first optical fiber cable connector, and a back hole in line with the circular center hole thereof, a rear casing, which has an externally threaded tubular outer coupling flange and a tubular inner coupling flange concentrically disposed around a center hole thereof for coupling the ferrule of a second optical fiber cable connector, and a front stub mounting tube fitted into the back hole on the front casing, and a split sleeve inserted into the circular center holes on the front and rear casings and having two opposite ends respectively stopped against an inside annular flange within the circular center hole on either casing.

Claims

1. A FC-type optical fiber cable connector'"'"'s adaptor of the type comprising a front casing having an externally threaded tubular outer coupling flange raised from a rectangular base wall thereof at an outer side around a center through hole on the rectangular base wall of said front casing for coupling optical fiber cable connector ferrules, a rear casing fastened to said front casing by screws and having an externally threaded tubular outer coupling flange raised from a rectangular base wall thereof at an outer side around a center through hole on the rectangular base wall of said rear casing for coupling optical fiber cable connector ferrules, and a circular split sleeve inserted into the center hole on said front casing and the center hole on said rear casing, wherein said front casing further comprises a tubular inner coupling flange raised from the base wall thereof and concentrically disposed within the tubular outer coupling flange thereof around the center hole thereof, an annular inside flange raised from the tubular inner coupling flange thereof on the inside around the center hole of said front casing and stopped against said split sleeve at one end, and a back hole on the base wall thereof at an opposite side in line with the center hole of said front casing;

said rear casing further comprises a tubular inner coupling flange raised from the base wall thereof and concentrically disposed within the tubular outer coupling flange thereof around the center hole thereof, an annular inside flange raised from the tubular inner coupling flange thereof on the inside around the center hole of said rear casing and stopped against said split sleeve at an opposite end, and a front stub mounting tube raised from the base wall thereof and fitted into the back hole on the base wall of said front casing.

2. The FC-type optical fiber cable connector'"'"'s adaptor of claim 1 wherein said front and rear casings are respectively integrally shape formed by die casting.
