Abstract
Abstract A connector plug for axially aligning an optical fiber in a receptacle bore is disclosed, comprising an elongate body having an axial passageway receiving the fiber therein, and a forward alignment nose portion having a profiled opening receiving a forward end of the fiber. The opening is defined by opposed V-grooves, with the V-grooves being separated by a transverse slot extending through the alignment nose portion. The nose portion further comprises external protrusion means for engaging the receptacle, and causing the opposed V-grooves to wedge against the fiber extending therebetween, for fiber centering.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
223 words
A connector for connecting optical fiber means of fiber optic cable means in axial alignment, comprising: receptacle means having bore means extending therethrough, said bore means having a substantially constant diameter surface means therealong; plug means having nose means, intermediate means and rear section means, said nose means, said intermediate means and said rear section means having axial bore means extending therethrough along which the fiber optic cable means will extend, said axial bore means along said nose means having opposed upper and lower profiled fiber-grasping means for grasping the optical fiber means of the fiber optic cable means therebetween, said fiber-grasping means being separated by transverse slot means extending through said nose means; said nose means and said intermediate means having a diameter slightly less than said constant diameter surface means of said bore means of said receptacle means so that said nose means and said intermediate means with the fiber optic cable means extending along said axial bore means and the optical fiber means grasped by said upper and lower profied fiber-grasping means can be positioned along said bore means with said nose means disposed adjacent one another; and protrusion means on said nose means and engagable with said surface means of said bore means to radially compress said fiber-grasping means onto the optical fiber means therein and axially align them.
Claim 2
Dependent Claim
223 words
A connector for connecting optical fiber means of fiber optic cable means in axial alignment, comprising: receptacle means having bore means extending therethrough, said bore means having a substantially constant diameter surface means therealong; plug means having nose means, intermediate means and rear section means, said nose means, said intermediate means and said rear section means having axial bore means extending therethrough along which the fiber optic cable means will extend, said axial bore means along said nose means having opposed upper and lower profiled fiber-grasping means for grasping the optical fiber means of the fiber optic cable means therebetween, said fiber-grasping means being separated by transverse slot means extending through said nose means; said nose means and said intermediate means having a diameter slightly less than said constant diameter surface means of said bore means of said receptacle means so that said nose means and said intermediate means with the fiber optic cable means extending along said axial bore means and the optical fiber means grasped by said upper and lower profied fiber-grasping means can be positioned along said bore means with said nose means disposed adjacent one another; and protrusion means on said nose means and engagable with said surface means of said bore means to radially compress said fiber-grasping means onto the optical fiber means therein and axially align them.
Claim 3
Dependent Claim
20 words
A connector as set forth in claim 1, wherein said opposed upper and lower profiled fiber-grasping means have V-shaped surfaces.
Claim 4
Dependent Claim
25 words
A connector as set forth in claim 1, wherein said intermediate means have annular flange means sealingly engaging said surface means of said bore means.
Claim 5
Dependent Claim
28 words
A connector as set forth in claim 1, wherein said receptacle means and said plug means have latch means for latching said plug means to said receptacle means.
Claim 6
Dependent Claim
45 words
A connector as set forth in claim 1, wherein said axial bore means along said rear section means is larger, securing means for engagement with said axial bore means along said rear section means for securing the fiber optic cable means in said plug means.
Claim 7
Dependent Claim
161 words
A fiber optic connector for terminating an end of fiber optic cable means and for connection within a substantially constant diameter bore means of receptacle means, comprising: plug means having nose means, intermediate means and rear section means, said nose means, said intermediate means and said rear section means having axial bore means extending therethrough along which the fiber optic cable means will extend, said axial bore means along said nose means having opposed upper and lower profiled fiber-grasping means for grasping the optical fiber means of the fiber optic cable means therebetween, said fiber-grasping means being separated by transverse slot means extending through said nose means; and protrusion means on said nose means and engageable with the substantially constant diameter bore means of the receptacle means when said nose means and said intermediate means are inserted into the bore means thereby radially compressing said fiber-grasping means onto the optical fiber means therein and axially aligning the optical fiber means therein.
Claim 8
Dependent Claim
161 words
A fiber optic connector for terminating an end of fiber optic cable means and for connection within a substantially constant diameter bore means of receptacle means, comprising: plug means having nose means, intermediate means and rear section means, said nose means, said intermediate means and said rear section means having axial bore means extending therethrough along which the fiber optic cable means will extend, said axial bore means along said nose means having opposed upper and lower profiled fiber-grasping means for grasping the optical fiber means of the fiber optic cable means therebetween, said fiber-grasping means being separated by transverse slot means extending through said nose means; and protrusion means on said nose means and engageable with the substantially constant diameter bore means of the receptacle means when said nose means and said intermediate means are inserted into the bore means thereby radially compressing said fiber-grasping means onto the optical fiber means therein and axially aligning the optical fiber means therein.
Claim 9
Dependent Claim
27 words
A fiber optic connector as set forth in claim 6, wherein annular flange means is located on said intermediate means for sealing engagement with the bore means.
Claim 10
Dependent Claim
22 words
A fiber optic connector as set forth in claim 6, wherein said opposed upper and lower profiled fiber-grasping means have V-shaped surfaces.
