Abstract
Abstract Apparatus for achieving an optical connection between an optical fiber and electro-optic device comprises a fiber optic connector comprising a pair of elongated connector elements having facing substantially flat surfaces and an elongated groove on at least one of the surfaces for receiving an optical fiber to be retained between the connector elements. A resilient clamping member maintains the connector elements in engagement with each other so as to retain the optical fiber in the groove. A coupling portion projecting from the clamping member for joining the clamping member with the electro-optic device in such a manner that an optical fiber retained in the connector is in optical alignment with a predetermined portion of the electrooptic device.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
178 words
Apparatus for producing a re-enterable optical connection between an optical fiber and an optical device other than an optical fiber, said apparatus comprising: a fiber optic connector comprising a pair of elongated connector elements having facing substantially flat surfaces and means defining an elongated groove in at least one of said surfaces for receiving an optical fiber to be retained between said connector elements; resilient clamping means for maintaining said connector elements in engagement with each other so as to retain said optical fiber in said groove; operating means for accommodating a tool for selectively temporarily overcoming the force of said resilient clamping means for parting said connector elements to an extent necessary to permit movement of an optical fiber in said elongated groove so as to provide for placement, removal, or longitudinal positioning of an optical fiber relative to said elongated groove; and coupling means for joining the connector with said optical device in such a manner that an optical fiber retained in said connector is in optical alignment with a predetermined portion of the optical device.
Claim 2
Dependent Claim
178 words
Apparatus for producing a re-enterable optical connection between an optical fiber and an optical device other than an optical fiber, said apparatus comprising: a fiber optic connector comprising a pair of elongated connector elements having facing substantially flat surfaces and means defining an elongated groove in at least one of said surfaces for receiving an optical fiber to be retained between said connector elements; resilient clamping means for maintaining said connector elements in engagement with each other so as to retain said optical fiber in said groove; operating means for accommodating a tool for selectively temporarily overcoming the force of said resilient clamping means for parting said connector elements to an extent necessary to permit movement of an optical fiber in said elongated groove so as to provide for placement, removal, or longitudinal positioning of an optical fiber relative to said elongated groove; and coupling means for joining the connector with said optical device in such a manner that an optical fiber retained in said connector is in optical alignment with a predetermined portion of the optical device.
Claim 3
Dependent Claim
65 words
Apparatus according to claim 1 wherein said resilient clamping means and said coupling means comprise a bracket member having an elongate resilient clamping portion for receiving and maintaining said connector elements therebetween and in engagement with each other with sufficient force of engagement to retain an optical fiber within said groove and a coupling portion of complementary configuration with said optical device for mounting thereto.
Claim 4
Dependent Claim
21 words
Apparatus according to claim 2 wherein said elongate resilient clamping portion of said bracket member comprises an elongated generally U-shaped channel.
Claim 5
Dependent Claim
26 words
Apparatus according to claim 3 wherein said coupling portion of said bracket member comprises a pair of substantially flat surfaces projecting perpendicularly outwardly of said channel.
Claim 6
Dependent Claim

Apparatus according to claim 2 wherein said bracket member is formed of a metallic material.
Claim 7
Dependent Claim
78 words
Apparatus according to claim 1 wherein said resilient clamping means and said coupling means comprise a resilient hinged housing member defining a first cavity therein for receiving and maintaining said connector elements in engagement with each other with sufficient force to retain an optical fiber within said groove, and a second cavity therein dimensioned and located for receiving said electro-optic device and aligning said predetermined portion thereof with one end of the fiber-receiving groove of said connector elements.
Claim 8
Dependent Claim
16 words
Apparatus according to claim 6 wherein said resilient housing member is formed from a polymer material.
Claim 9
Dependent Claim
68 words
Apparatus according to claim 6 wherein said resilient hinged housing member comprises two complementary housing halves, and further including an elongate complementary rib and groove and complementary alignment projections and recesses formed to one side of the axial center of respective ones of said housing halves for interengagement by sonic welding or the like to thereby define a resilient clamshell-like member for grippingly engaging said connector elements therebetween.
Claim 10
Dependent Claim
36 words
Apparatus according to claim 6 and further including a retaining member of complementary form for engagement with said resilient hinged housing member about said second cavity therein for retaining said optical device within said second cavity.
Claim 11
Dependent Claim
45 words
Apparatus according to claim 6 wherein said resilient housing member further includes a fiber jacket terminating portion projecting from an end of said first cavity oppositely of said second cavity, such that said terminating portion, said second cavity and said first cavity are coaxially aligned.
Claim 12
Dependent Claim
26 words
Apparatus according to claim 10 wherein said fiber jacket terminating portion is substantially cylindrical in shape, having a plurality of axially spaced circumferential annular raised ribs.
Claim 13
Dependent Claim
