Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 167 words
Apparatus used in an optical connector assembly, comprising: a rigid tubular ferrule holder having a slotted outer flange between first and second holder terminal ends, a light waveguide ferrule on the first holder terminal end and heat shrinkable tubing secured over the second holder terminal end; a rigid tubular latching body carried on the heat shrinkable tubing and having an outer flange between an outwardly threaded first latching body terminal end and an outwardly knurled second latching body tubular end, said outwardly threaded first latching body terminal end having a tongue engaging the slotted outer flange of the ferrule holder to prevent rotation of the latching body with respect to the ferrule holder; a coil spring carried on the ferrule holder over the heat shrinkable tubing; a rigid tubular shroud having an outer flange and an inwardly threaded terminal end engaging the outwardly threaded first latching body terminal end; and, a rigid tubular coupling nut carried between the outer flanges of the latching body and the shroud.
Claim 2
Dependent Claim 167 words
Apparatus used in an optical connector assembly, comprising: a rigid tubular ferrule holder having a slotted outer flange between first and second holder terminal ends, a light waveguide ferrule on the first holder terminal end and heat shrinkable tubing secured over the second holder terminal end; a rigid tubular latching body carried on the heat shrinkable tubing and having an outer flange between an outwardly threaded first latching body terminal end and an outwardly knurled second latching body tubular end, said outwardly threaded first latching body terminal end having a tongue engaging the slotted outer flange of the ferrule holder to prevent rotation of the latching body with respect to the ferrule holder; a coil spring carried on the ferrule holder over the heat shrinkable tubing; a rigid tubular shroud having an outer flange and an inwardly threaded terminal end engaging the outwardly threaded first latching body terminal end; and, a rigid tubular coupling nut carried between the outer flanges of the latching body and the shroud.
Claim 3
Dependent Claim 36 words
Apparatus as recited in claim 1 further comprising a buffer tube holding a light waveguide, the buffer tube secured by curing the heat shrinkable tubing thereover and the light waveguide secured within the light waveguide ferrule.
Claim 4
Dependent Claim 174 words
Apparatus used in an optical connector assembly, comprising: a rigid tubular ferrule holder having a slotted outer flange between first and second holder terminal ends, a light waveguide ferrule on the first holder terminal end and heat shrinkable tubing secured over the second holder terminal end; a rigid tubular latching body carried on the heat shrinkable tubing and having an outer flange between a first latching body terminal end and an outwardly knurled second latching body terminal end, said first latching body terminal end having first engagement means for engaging the slotted outer flange of the ferrule holder to prevent rotation of the latching body with respect thereto and a second engagement means; a coil spring carried on the ferrule holder over the heat shrinkable tubing; a rigid tubular end member having an outer flange and a terminal end having third engagement means for engaging the second engagement means of the latching body; and, a rigid tubular outer member carried between the outer flanges of the latching body and the rigid tubular end member.
Claim 5
Dependent Claim 174 words
Apparatus used in an optical connector assembly, comprising: a rigid tubular ferrule holder having a slotted outer flange between first and second holder terminal ends, a light waveguide ferrule on the first holder terminal end and heat shrinkable tubing secured over the second holder terminal end; a rigid tubular latching body carried on the heat shrinkable tubing and having an outer flange between a first latching body terminal end and an outwardly knurled second latching body terminal end, said first latching body terminal end having first engagement means for engaging the slotted outer flange of the ferrule holder to prevent rotation of the latching body with respect thereto and a second engagement means; a coil spring carried on the ferrule holder over the heat shrinkable tubing; a rigid tubular end member having an outer flange and a terminal end having third engagement means for engaging the second engagement means of the latching body; and, a rigid tubular outer member carried between the outer flanges of the latching body and the rigid tubular end member.
