Abstract
Abstract An optical connector (1) comprises, a rigid body (2) with an axial bore (3), a sleeve (7) surrounding the rigid body (2) and having a sleeve section (9), a deformable means (10) in the sleeve section (9) and having an axial passage (11) aligned with the bore (3), an optical waveguide (14) secured in the bore (3) and having a first optical face and a second optical face, the axial passage (11) and the sleeve section (9) having open ends (18,19) to admit an optical fiber (22) in concentric alignment with the waveguide (14), and the deformable means (10) constructed for radial reduction of the passage (11) to grip the optical fiber (22).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
183 words
A connector comprising, a rigid body with an axial bore, a sleeve encircling the rigid body and having an integral sleeve section projecting beyond a rear end of the rigid body, radially deformable means encircled concentrically by the sleeve section and having an axial passageway aligned with the bore, an enlarged entrance of the bore recessed in an end of the rigid body and positioned in alignment with the passage, an optical waveguide secured in the bore of the rigid body and having a first optical face positioned at a front end of the rigid body, and having a second optical face in the connector aligned with the axial passage of the radially deformable means, the axial passage and the sleeve section having open ends to admit an optical fiber having a distal end finished with an optical face positioned in colinear alignment with the second optical face of the waveguide, and the radially deformable means being fabricated of a shape memory material constructed for radial reduction of the passage by shape memory reduction to grip an optical fiber admitted in the passage.
Claim 2
Dependent Claim
183 words
A connector comprising, a rigid body with an axial bore, a sleeve encircling the rigid body and having an integral sleeve section projecting beyond a rear end of the rigid body, radially deformable means encircled concentrically by the sleeve section and having an axial passageway aligned with the bore, an enlarged entrance of the bore recessed in an end of the rigid body and positioned in alignment with the passage, an optical waveguide secured in the bore of the rigid body and having a first optical face positioned at a front end of the rigid body, and having a second optical face in the connector aligned with the axial passage of the radially deformable means, the axial passage and the sleeve section having open ends to admit an optical fiber having a distal end finished with an optical face positioned in colinear alignment with the second optical face of the waveguide, and the radially deformable means being fabricated of a shape memory material constructed for radial reduction of the passage by shape memory reduction to grip an optical fiber admitted in the passage.
Claim 3
Dependent Claim
22 words
