Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
An optical fiber connector terminal comprising: a sleeve; a plurality of pins disposed equidistance from a center within said sleeve to define a receiving aperture; a plurality of inner ridges disposed between said sleeve and said pins; and an optical fiber inserted into and bonded to said receiving aperture said sleeve with said inner ridges has a hardness less than that of said pins so that when said sleeve is reduced in diameter said inner ridges fill spaces between said sleeve and said pins.
Claim 2
Dependent Claim
84 words
An optical fiber connector terminal comprising: a sleeve; a plurality of pins disposed equidistance from a center within said sleeve to define a receiving aperture; a plurality of inner ridges disposed between said sleeve and said pins; and an optical fiber inserted into and bonded to said receiving aperture said sleeve with said inner ridges has a hardness less than that of said pins so that when said sleeve is reduced in diameter said inner ridges fill spaces between said sleeve and said pins.
Claim 3
Dependent Claim
27 words
The optical fiber connector terminal of claim 1, wherein said plurality of pins and said plurality of inner ridges are three pins and three inner ridges, respectively.
Claim 4
Dependent Claim
26 words
The optical fiber connector terminal of claim 1, wherein said plurality of pins and said plurality of inner ridges are five pins and five inner ridges.
Claim 5
Independent Claim
106 words
A method of making an optical fiber connector terminal, which comprises the steps of: providing a plurality of inner ridges on an inside of a sleeve; placing a plurality of pins within said sleeve such that said pins having a hardness greater than that of said sleeve are disposed around a center of said sleeve; reducing a diameter of said sleeve so that said inner ridges 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 6
Independent Claim
106 words
A method of making an optical fiber connector terminal, which comprises the steps of: providing a plurality of inner ridges on an inside of a sleeve; placing a plurality of pins within said sleeve such that said pins having a hardness greater than that of said sleeve are disposed around a center of said sleeve; reducing a diameter of said sleeve so that said inner ridges 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
Dependent Claim
21 words
The method of claim 4, wherein said plurality of pins and said plurality of ridges are three pins and three ridges.
Claim 8
Dependent Claim
22 words
The method of claim 4, wherein said plurality of pins and said plurality of ridges are five pins and five inner ridges.
Claim 9
Dependent Claim
30 words
The method of claim 4, wherein said pins are made from hardened stainless steel while said sleeve with said inner ridges is made from stainless steel which is not hardened.
Claim 10
Dependent Claim
26 words
The method of claim 4, wherein said diameter reducing step comprises the step of subjecting said sleeve with said inner ridges to a rotary forging process.
Claim 11
Dependent Claim
25 words
The method of claim 4, wherein said diameter reducing step comprises the step of subjecting said sleeve with said inner ridges to a drawing process.
Claim 12
Dependent Claim
25 words
The method of claim 4, wherein said diameter reducing step comprises the step of subjecting said sleeve with said inner ridges to a press process.
