Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
An optical fiber connector terminal comprising: a sleeve made of a first metallic material; a plurality of pins made of a second metallic material and disposed equidistance form a center within said sleeve to define a receiving aperture; a plurality of filler means made from a third metallic material for filling spaces between said sleeve and said pins; and an optical fiber inserted into and bonded to said receiving aperture; said first and third metallic materials being softer than said second metallic material so that when said sleeve is reduced in diameter, said hard metallic material collapse under pressure to fill spaces between said sleeve and said pins.
Claim 2
Dependent Claim
108 words
An optical fiber connector terminal comprising: a sleeve made of a first metallic material; a plurality of pins made of a second metallic material and disposed equidistance form a center within said sleeve to define a receiving aperture; a plurality of filler means made from a third metallic material for filling spaces between said sleeve and said pins; and an optical fiber inserted into and bonded to said receiving aperture; said first and third metallic materials being softer than said second metallic material so that when said sleeve is reduced in diameter, said hard metallic material collapse under pressure to fill spaces between said sleeve and said pins.
Claim 3
Dependent Claim
18 words
The optical fiber connector terminal of claim 1, wherein said filler means are a plurality of filler rods.
Claim 4
Dependent Claim
25 words
The optical fiber connector terminal of claim 1, wherein said filler means are a plurality of inner ridges extending toward a center of said sleeve.
Claim 5
Dependent Claim
17 words
The optical fiber connector terminal of claim 1, wherein said filler means reformed material of said sleeve.
Claim 6
Independent Claim
108 words
A method of making an optical fiber connector terminal, which comprises the steps of: alternatingly placing a plurality of pins and a plurality of filler means with in a sleeve such that said pins are disposed around a center of said sleeve, said pins having a hardness greater than that of said sleeve and said filler means; reducing a diameter of said sleeve so that said filler means 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 bonding an optical fiber in said receiving aperture to provide an optical fiber connector terminal.
Claim 7
Independent Claim
108 words
A method of making an optical fiber connector terminal, which comprises the steps of: alternatingly placing a plurality of pins and a plurality of filler means with in a sleeve such that said pins are disposed around a center of said sleeve, said pins having a hardness greater than that of said sleeve and said filler means; reducing a diameter of said sleeve so that said filler means 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 bonding an optical fiber in said receiving aperture to provide an optical fiber connector terminal.
Claim 8
Dependent Claim
21 words
The method of claim 5, wherein said filler means are filler rods having a hardness less than that of said pins.
Claim 9
Dependent Claim
19 words
The method of claim 5, wherein said filler means are inner ridges extending toward said center of said sleeve.
Claim 10
Dependent Claim
15 words
The method of claim 5, wherein said filler means are deformed portions of said sleeve.
