Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A fiber optic connector comprising: a housing shell having an axially aligned aperture running from the aft end to the forward end of said shell, such aft end adapted to receive fiber optic leads, said shell having fill and exit apertures for potting; a clamping nut forming a collar around the forward end of said shell, said clamping nut adapted to be affixed to a mating connector; an insert alignment bushing being inserted in the forward end of said shell, said bushing comprising a solid slug of material having keying pin apertures, anchor pin apertures and fiber optic lead apertures, respective members of said keying pin apertures and said anchor pin apertures having the same axis; anchor pins inserted in said anchor pin apertures; and keying pins inserted in said keying pin apertures.
Claim 2
Dependent Claim
133 words
A fiber optic connector comprising: a housing shell having an axially aligned aperture running from the aft end to the forward end of said shell, such aft end adapted to receive fiber optic leads, said shell having fill and exit apertures for potting; a clamping nut forming a collar around the forward end of said shell, said clamping nut adapted to be affixed to a mating connector; an insert alignment bushing being inserted in the forward end of said shell, said bushing comprising a solid slug of material having keying pin apertures, anchor pin apertures and fiber optic lead apertures, respective members of said keying pin apertures and said anchor pin apertures having the same axis; anchor pins inserted in said anchor pin apertures; and keying pins inserted in said keying pin apertures.
Claim 3
Dependent Claim
24 words
