Abstract

Abstract A detachable fiber optic connector provides connection from an optical source or sink through a hermetic connection to a removable attached optical fiber. Ferrules and a split ring are used for alignment. A variety of alternative embodiments are illustrated for providing coupling force between the ferrules and retaining forces to prevent movement of the connection during movement of the fiber relative to the optical source or sink. These detachable fiber optic connectors provide great benefit when combined with hermetic packaging.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 375 words
A low profile detachable fiber optic connector detachably interconnecting an hermetically packaged optic source or sink with a first optic waveguide comprising: an hermetic enclosure enclosing an optic source or sink having a pass-through hole therein, and having first and second retention means extending from said hermetic enclosure exterior, said first and second retention means adjacent to said pass-through hole but on opposite sides thereof; a second optic waveguide having a first termination and a second termination, said second optic waveguide aligned to optically interact with said optic source or sink from said first termination of said second optic waveguide, said second optic waveguide passing through said hermetic enclosure at said pass-through hole; a first ferrule, said first ferrule surrounding said first optic waveguide adjacent a termination of said first optic waveguide; a second ferrule, said second ferrule surrounding said second optic waveguide adjacent said second termination and sealed thereto, said second ferrule further sealed to said pass-through hole so that said second optic waveguide and said second ferrule hermetically seal said pass-through hole; an interfacing mounting frame having a first opening therethrough co-axial with said first and said second ferrules and generally concentric therewith, said interfacing mounting frame further having second and third openings therethrough with said first and second retention means passing therethrough; an alignment sleeve co-axial, generally concentric with and mechanically coupled to said first and second ferrules for maintaining relative alignment therebetween, said alignment sleeve also co-axial and internally concentric with said interfacing mounting frame; a generally flat spring retainer transverse to said first ferrule and having a center section mechanically engaging said first ferrule, said spring retainer further having first and second resilient extensions extending from said center section of said spring retainer also generally transverse to said first ferrule, said first and second resilient extensions each including a hole therethrough through which said retention means passes, said retention means engaging said spring retainer to retain said spring retainer in a spring biased position against said interfacing mounting frame and said first ferrule, thereby retaining said interfacing mounting frame in fixed position relative to said hermetic enclosure and said spring retainer, while simultaneously biasing said second termination of said second optic waveguide against said termination of said first optic waveguide.
Claim 2
Dependent Claim 375 words
A low profile detachable fiber optic connector detachably interconnecting an hermetically packaged optic source or sink with a first optic waveguide comprising: an hermetic enclosure enclosing an optic source or sink having a pass-through hole therein, and having first and second retention means extending from said hermetic enclosure exterior, said first and second retention means adjacent to said pass-through hole but on opposite sides thereof; a second optic waveguide having a first termination and a second termination, said second optic waveguide aligned to optically interact with said optic source or sink from said first termination of said second optic waveguide, said second optic waveguide passing through said hermetic enclosure at said pass-through hole; a first ferrule, said first ferrule surrounding said first optic waveguide adjacent a termination of said first optic waveguide; a second ferrule, said second ferrule surrounding said second optic waveguide adjacent said second termination and sealed thereto, said second ferrule further sealed to said pass-through hole so that said second optic waveguide and said second ferrule hermetically seal said pass-through hole; an interfacing mounting frame having a first opening therethrough co-axial with said first and said second ferrules and generally concentric therewith, said interfacing mounting frame further having second and third openings therethrough with said first and second retention means passing therethrough; an alignment sleeve co-axial, generally concentric with and mechanically coupled to said first and second ferrules for maintaining relative alignment therebetween, said alignment sleeve also co-axial and internally concentric with said interfacing mounting frame; a generally flat spring retainer transverse to said first ferrule and having a center section mechanically engaging said first ferrule, said spring retainer further having first and second resilient extensions extending from said center section of said spring retainer also generally transverse to said first ferrule, said first and second resilient extensions each including a hole therethrough through which said retention means passes, said retention means engaging said spring retainer to retain said spring retainer in a spring biased position against said interfacing mounting frame and said first ferrule, thereby retaining said interfacing mounting frame in fixed position relative to said hermetic enclosure and said spring retainer, while simultaneously biasing said second termination of said second optic waveguide against said termination of said first optic waveguide.
Claim 3
Dependent Claim 40 words
The low profile detachable fiber optic connector of claim 1 further comprising a notched region in an interior wall of said hermetic enclosure into which said ferrule holder is engaged, said ferrule holder carrying thereon said optic source or sink.
Claim 4
Dependent Claim 22 words
The low profile detachable fiber optic connector of claim 1 wherein said spring retainer comprises an integral piece of formed sheet metal.
Claim 5
Dependent Claim 26 words
The low profile detachable fiber optic connector of claim 3 wherein said center section of said spring retainer is bowed slightly towards said interfacing mounting frame.
Claim 6
Dependent Claim 17 words
The low profile detachable fiber optic connector of claim 1 wherein said optic waveguide comprises optical fiber.
Claim 7
Dependent Claim 26 words
The low profile detachable fiber optic connector of claim 1 wherein said optic source or sink comprises an optoelectronic device for generating or receiving optical signals.
Claim 8
Dependent Claim 92 words
A male fiber optic connector of low mass comprising: an optical fiber; a cylindrical ferrule having a precise bore therein, said optical fiber passing therethrough and permanently attached thereto; a generally flat spring retainer transverse to said ferrule having a center section having a hole formed therein through which said optical fiber passes, said spring retainer center section mechanically engaging said ferrule, said spring retainer further having two resilient extensions extending from said center section of said spring retainer also generally transverse to said ferrule, said resilient extensions including a hole therethrough.
Claim 9
Dependent Claim 92 words
A male fiber optic connector of low mass comprising: an optical fiber; a cylindrical ferrule having a precise bore therein, said optical fiber passing therethrough and permanently attached thereto; a generally flat spring retainer transverse to said ferrule having a center section having a hole formed therein through which said optical fiber passes, said spring retainer center section mechanically engaging said ferrule, said spring retainer further having two resilient extensions extending from said center section of said spring retainer also generally transverse to said ferrule, said resilient extensions including a hole therethrough.
Claim 10
Dependent Claim 23 words
The male fiber optic connector of claim 7 further comprising a gasket means concentric to said ferrule and adjacent to said connector body.
