Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 100 words
An optical fiber connector terminal comprising: a sleeve made of a first steel material a plurality of pins of a second steel material disposed equidistance from a center within said sleeve to define a receiving aperture; a plurality of filler rods of a third steel material disposed between said sleeve and said pins; an optical fiber inserted into and bonded to said receiving aperture; said first and second steel materials being softer than said third steel material; and said sleeve being reduced in diameter so that said third steel material collapses and fills spaced between said sleeve and said pins.
Claim 2
Dependent Claim 100 words
An optical fiber connector terminal comprising: a sleeve made of a first steel material a plurality of pins of a second steel material disposed equidistance from a center within said sleeve to define a receiving aperture; a plurality of filler rods of a third steel material disposed between said sleeve and said pins; an optical fiber inserted into and bonded to said receiving aperture; said first and second steel materials being softer than said third steel material; and said sleeve being reduced in diameter so that said third steel material collapses and fills spaced between said sleeve and said pins.
Claim 3
Dependent Claim 16 words
The optical fiber connector terminal of claim 1, wherein said plurality of pins are three pins.
Claim 4
Dependent Claim 16 words
The optical fiber connector terminal of claim 1, wherein said plurality of pins are five pins.
Claim 5
Dependent Claim 17 words
The optical fiber connector terminal of claim 1, wherein said filler rods have a circular cross section.
Claim 6
Dependent Claim 17 words
The optical fiber connector terminal of claim 1, wherein said filler rods have a triangular cross section.
Claim 7
Dependent Claim 17 words
The optical fiber connector terminal of claim 1, wherein said filler rods have a polygonal cross section.
Claim 8
Dependent Claim 24 words
The optical fiber connector terminal of claim 1, wherein said sleeve and said filler rods have a hardness less than that of said pins.
Claim 9
Dependent Claim 33 words
The optical fiber connector terminal of claim 1, wherein said pins are made from hardened stainless steel while said sleeve and said filler rods are made from stainless steel which is not hardened.
Claim 10
Independent Claim 94 words
A method of making an optical fiber connector terminal, which comprises the steps of: placing alternately a plurality of pins and a plurality of filler rods within a sleeve such that said pins are disposed around a center of said sleeve; reducing a diameter of said sleeve so that said filler rods collapse and fill spaces between said sleeve and said pins, thereby disposing said pins equidistance from said center to form a receiving aperture at said center; and securing an optical fiber in said receiving aperture to provide an optical fiber connector terminal.
Claim 11
Independent Claim 94 words
A method of making an optical fiber connector terminal, which comprises the steps of: placing alternately a plurality of pins and a plurality of filler rods within a sleeve such that said pins are disposed around a center of said sleeve; reducing a diameter of said sleeve so that said filler rods collapse and fill spaces between said sleeve and said pins, thereby disposing said pins equidistance from said center to form a receiving aperture at said center; and securing an optical fiber in said receiving aperture to provide an optical fiber connector terminal.
Claim 12
Dependent Claim 13 words
The method of claim 9, wherein said plurality of pins are three pins.
Claim 13
Dependent Claim 13 words
The method of claim 9, wherein said plurality of pins are five pins.
Claim 14
Dependent Claim 14 words
The method of claim 9, wherein said filler rods have a circular cross section.
Claim 15
Dependent Claim 14 words
The method of claim 9, wherein said filler rods have a triangular cross section.
Claim 16
Dependent Claim 14 words
The method of claim 9, wherein said filler rods have a polygonal cross section.
Claim 17
Dependent Claim 30 words
The method of claim 9, wherein said pins are made from hardened stainless steel while said sleeve and said filler rods are made from stainless steel which is not hardened.
Claim 18
Dependent Claim 26 words
The method of claim 9, wherein said diameter reducing step comprises the step of subjecting said sleeve with said filler rods to a rotary forging process.
Claim 19
Dependent Claim 25 words
The method of claim 9, wherein said diameter reducing step comprises the step of subjecting said sleeve with said filler rods to a drawing process.
Claim 20
Dependent Claim 25 words
The method of claim 9, wherein said diameter reducing step comprises the step of subjecting said sleeve with said filler rods to a press process.
