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 low insertion force to abut the receptacle fiber optic ferrule therein. A leaf spring is mounted in the channel. The plug connector member carries an actuating sleeve which engages a central portion of the leaf spring upon mating of the connector members urging the spring inwardly into the V-channel. The spring is constructed such that when it is actuated, the spring biases both the ferrules in the connector into abutting relationship.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
124 words
A fiber optic connector comprising: first and second 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 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 movable relative to said spring means for urging said spring means toward said channel; and said spring means being adapted to exert forward biasing forces on both the ferrules upon actuation thereof by said actuating means.
Claim 2
Dependent Claim
124 words
A fiber optic connector comprising: first and second 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 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 movable relative to said spring means for urging said spring means toward said channel; and said spring means being adapted to exert forward biasing forces on both the ferrules upon actuation thereof by said actuating means.
Claim 3
Dependent Claim
28 words
A fiber optic connector as set forth in claim 1 wherein: said actuating means automatically urges said spring means toward said channel upon mating of said connector members.
Claim 4
Dependent Claim
59 words
A fiber optic connector as set forth in claim 1 wherein: said spring means includes a central section and a pair of spring arms extending in opposite axial directions from said central section, each said arm being located to engage a ferrule; and said actuating means engages said central section of said spring means to actuate said spring arms.
Claim 5
Dependent Claim
70 words
A fiber optic connector as set forth in claim 3 wherein: said connector members are axially matable; said first connector member includes a radial opening communicating with said passage; said central section of said spring means extending outwardly through said opening; and said actuating means comprising a forwardly extending member on said second connector member engaging said central section of said spring means upon axial mating of said connector members.
Claim 6
Dependent Claim
85 words
A fiber optic connector as set forth in claim 3 wherein: said central section of said spring means has a generally dovetail configuration providing an axially extending leg, a forward inwardly and rearwardly extending leg and a rear inwardly and forwardly extending leg; one of said spring arms being joined to said forward leg and extending forwardly therefrom and inwardly toward said channel; and the other of said spring arms being joined to said rear leg and extending rearwardly therefrom and inwardly toward said channel.
Claim 7
Dependent Claim
39 words
A fiber optic connector as set forth in claim 5 wherein: said actuating means embodies a beveled cam surface engageable with said forward leg for effecting rearward pivotable movement thereof whereby said one spring arm pivots inwardly and rearwardly.
Claim 8
Dependent Claim
43 words
A fiber optic connector as set forth in claim 6 wherein: said first connector member embodies a forwardly directed beveled cam surface engagable with said rear leg for effecting forward pivotable movement thereof whereby said other spring arm pivots inwardly and forwardly. PG,14
Claim 9
Dependent Claim
46 words
A fiber optic connector as set forth in claim 5 wherein: said actuating means functions to axially compress said central section of said spring means to cause said one spring arm to pivot inwardly and rearwardly and said other spring arm to pivot inwardly and forwardly.
Claim 10
Dependent Claim
139 words
A fiber optic connector as set forth in claim 5 wherein: said connector members are axially matable; said first connector member comprises a body having a bore therethrough and a forwardly opening enlarged recess; a sleeve is mounted in said bore extending forwardly into said recess and spaced radially from the wall thereof defining an annual channel therebetween, said passage being provided in said sleeve; a radial opening extending through the wall of said sleeve opposite to said V-shaped channel and in front of the bottom of said recess; said central section of said spring means extending outwardly through said opening into said annular channel; and said actuating means comprising a forwardly extending sleeve on said second connector member slidable into said annular channel for engaging said central section of said spring means upon mating of said connector members.
Claim 11
Dependent Claim
46 words
A fiber optic connector as set forth in claim 9 wherein: said actuating means functions to axially compress said central section of said spring means to cause said one spring arm to pivot inwardly and rearwardly and said other spring arm to pivot inwardly and forwardly.
Claim 12
Dependent Claim
68 words
A fiber optic connector as set forth in claim 2 wherein: said first connector member comprises a body having a recess therein opening at its forward mating end; said actuating means comprises a sleeve portion on said second connector member slidable into said recess upon mating of said connector members; and said spring means has an actuating surface exposed in said recess and engageable by said sleeve portion.
Claim 13
Dependent Claim
141 words
A fiber optic connector comprising: first and second mating connector members each carrying an optical fiber ferrule; said first connector member having a passage therethrough receiving one of said ferrules in one end thereof; the ferrule in said second connector member being slidable into the other end of said passage upon mating of said connector members; 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 in said passage adapted to be urged toward said channel for biasing said ferrules into said channel to align the optical fibers in said ferrules; actuating means movable relative to said spring means for urging said spring means toward said channel; and said spring means exerting forward biasing forces on both said ferrules upon actuation thereof by said actuating means.
Claim 14
Dependent Claim
141 words
A fiber optic connector comprising: first and second mating connector members each carrying an optical fiber ferrule; said first connector member having a passage therethrough receiving one of said ferrules in one end thereof; the ferrule in said second connector member being slidable into the other end of said passage upon mating of said connector members; 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 in said passage adapted to be urged toward said channel for biasing said ferrules into said channel to align the optical fibers in said ferrules; actuating means movable relative to said spring means for urging said spring means toward said channel; and said spring means exerting forward biasing forces on both said ferrules upon actuation thereof by said actuating means.
