Abstract
Abstract An actuated fiber optic connector is disclosed in which the plug and receptacle connector members are axially mated with the fiber optic ferrule in the plug connector member sliding into a V-shaped channel in the receptacle connector member with zero insertion force to abut the receptacle fiber optic ferrule therein. A leaf spring is mounted in the channel. An axially slidable actuating sleeve is mounted on the plug connector member. When the connector members are mated, the sleeve engages a radially shiftable plunger in the receptacle, forcing the plunger inwardly to automatically urge the spring, and thus the ferrules, into the V-channel thereby precisely laterally aligning the optical fibers in the ferrules.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A fiber optic connector comprising: first and second axially mating connector members each adapted to carry an optical fiber ferrule; said first connector member having a passage therethrough adapted to receive the ferrules in its opposite ends; said passage including a pair of longitudinally extending flat sides disposed at an angle relative to each other defining a generally V-shaped channel; spring means carried by said first connector member and mounted in said passage adapted to be urged toward said channel for biasing the ferrules into said channel to align the optical fibers in the ferrules; and actuating means carried by said second connector member axially slidable relative to said first connector member and said spring means, said actuating means being operatively with said spring means for automatically urging said spring means toward said channel upon axial mating of said connector members.
Claim 2
Dependent Claim
141 words
A fiber optic connector comprising: first and second axially mating connector members each adapted to carry an optical fiber ferrule; said first connector member having a passage therethrough adapted to receive the ferrules in its opposite ends; said passage including a pair of longitudinally extending flat sides disposed at an angle relative to each other defining a generally V-shaped channel; spring means carried by said first connector member and mounted in said passage adapted to be urged toward said channel for biasing the ferrules into said channel to align the optical fibers in the ferrules; and actuating means carried by said second connector member axially slidable relative to said first connector member and said spring means, said actuating means being operatively with said spring means for automatically urging said spring means toward said channel upon axial mating of said connector members.
Claim 3
Dependent Claim
39 words
A fiber optic connector as set forth in claim 1 wherein: said second connector member has coupling means thereon for releasable holding said connector members in mating relationship; and said coupling means embodying a portion of said actuating means.
Claim 4
Dependent Claim
24 words
A fiber optic connector as set forth in claim 1 wherein: said spring means is an elongated leaf spring extending lengthwise in said passage.
Claim 5
Dependent Claim
221 words
A fiber optic connector comprising: first and second axially mating connector members each adapted to carry an optical fiber ferrule; said first connector member having a passage therethrough adapted to receive the ferrules in its opposite ends; said passage including a pair of longitudinally extending flat sides disposed at an angle relative to each other defining a generally V-shaped channel; spring means mounted in said passage adapted to be urged toward said channel for biasing the ferrules into said channel to align the optical fibers in the ferrules; actuating means carried by said second connector member axially slidable relative to said first connector member and said spring means, said actuating means being operatively associated with said spring means for automatically urging said spring means toward said channel upon axial mating of said connector members; said second connector member having coupling means thereon for releasably holding said connector members in mating relationship; said coupling means embodying a portion of said actuating means; a transverse bore in said first connector member extending from the wall of said passage opposite to said channel to the exterior of said connector member; a plunger in said bore having an inner end engaging said spring means and an outer end; and said actuating means engaging said outer end of said plunger upon mating of said connector members.
Claim 6
Dependent Claim
221 words
A fiber optic connector comprising: first and second axially mating connector members each adapted to carry an optical fiber ferrule; said first connector member having a passage therethrough adapted to receive the ferrules in its opposite ends; said passage including a pair of longitudinally extending flat sides disposed at an angle relative to each other defining a generally V-shaped channel; spring means mounted in said passage adapted to be urged toward said channel for biasing the ferrules into said channel to align the optical fibers in the ferrules; actuating means carried by said second connector member axially slidable relative to said first connector member and said spring means, said actuating means being operatively associated with said spring means for automatically urging said spring means toward said channel upon axial mating of said connector members; said second connector member having coupling means thereon for releasably holding said connector members in mating relationship; said coupling means embodying a portion of said actuating means; a transverse bore in said first connector member extending from the wall of said passage opposite to said channel to the exterior of said connector member; a plunger in said bore having an inner end engaging said spring means and an outer end; and said actuating means engaging said outer end of said plunger upon mating of said connector members.
Claim 7
Dependent Claim
34 words
A fiber optic connector as set forth in claim 4 wherein: said outer end of said plunger extends outside said bore; and said actuating means embodies a cam surface engageable with said outer end.
