Abstract
Abstract An optical fiber connector assembly having a housing with front and rear barrels is readily securable to a printed circuit board. A laser device is positioned in the rear barrel portion and an optical fiber ferrule device is insertable into the front barrel portion for receiving laser light. An insert member means for positioning the ferrule means in proximity to the laser means is disposed in the rear barrel portion forward of the laser means.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
112 words
An optical fiber connector assembly comprising: a housing having a front and rear barrel portions; laser means disposed in the rear barrel portion of the housing for directing laser light in a direction toward the front barrel portion; optical fiber ferrule means for receiving laser light from the laser means, the ferrule means being insertable into the front barrel portion of the housing; and longitudinally movable insert member means for positioning the ferrule means in proper proximity to the laser means substantially independent of the longitudinal dimension of the laser means, the insert member being movably mounted in the rear barrel portion forward of the laser means toward the front barrel portion.
Claim 2
Dependent Claim
112 words
An optical fiber connector assembly comprising: a housing having a front and rear barrel portions; laser means disposed in the rear barrel portion of the housing for directing laser light in a direction toward the front barrel portion; optical fiber ferrule means for receiving laser light from the laser means, the ferrule means being insertable into the front barrel portion of the housing; and longitudinally movable insert member means for positioning the ferrule means in proper proximity to the laser means substantially independent of the longitudinal dimension of the laser means, the insert member being movably mounted in the rear barrel portion forward of the laser means toward the front barrel portion.
Claim 3
Dependent Claim
34 words
An optical fiber connector assembly according to claim 1, wherein the insert member means includes aperture means for restricting light of the emitter means from propagating into the front barrel portion of the housing.
Claim 4
Dependent Claim
52 words
An optical fiber connector assembly according to claim 1, wherein the barrel portion includes a first counterbore for receiving the laser means, the first counterbore having a diameter smaller than an outer diameter of the laser means such that the laser means is secured in the first counterbore by a press fit.
Claim 5
Dependent Claim
50 words
An optical fiber connector assembly according to claim 3, wherein the rear barrel portion further includes a second counterbore for receiving the longitudinally movable insert member means, the second counterbore having a smaller diameter than the first counterbore and being located adjacent the first counterbore toward the front barrel portion.
Claim 6
Dependent Claim
69 words
An optical fiber connector assembly according to claim 2, wherein the longitudinally movable insert member means includes two opposing counterbores separated by the aperture means, the aperture means being a membrane with a hole positioned concentric with the opposing counterbore, the first of the counterbores being sized to receive the ferrule means, the second of the counterbores being sized to receive at least a portion of the laser means.
Claim 7
Dependent Claim
50 words
An optical fiber connector assembly according to claim 5, wherein the membrane is positioned along a longitudinal axis of the longitudinally movable insert member means such that the ferrule means is positioned at the proper proximity to the laser means when the ferrule means is in contact with the membrane.
Claim 8
Dependent Claim
44 words
An optical fiber connector assembly according to claim 5, wherein the hole in the membrane is sized to obstruct a significant portion of the divergent light that originates from the laser means which would not normally be captures by the core of the fiber.
Claim 9
Dependent Claim
25 words
An optical fiber connector assembly according to claim 1, further comprising means for maintaining the ferrule means in loaded engagement with the insert member means.
Claim 10
Dependent Claim
24 words
An optical fiber connector assembly according to claim 1, wherein the housing includes integral means for securing the housing to a printed circuit board.
Claim 11
Dependent Claim
85 words
An optical fiber connector housing assembly comprising: front and rear barrel portions; laser means disposed in the rear barrel portion for directing laser light in a direction toward the front barrel portion; longitudinally movable insert member means for maintaining a means for receiving the laser light in proper proximity to the laser means substantially independent of the longitudinal dimension of the laser light source, the insert member being movably disposed in the rear barrel portion forward of the laser means toward the front barrel portion.
Claim 12
Dependent Claim
85 words
An optical fiber connector housing assembly comprising: front and rear barrel portions; laser means disposed in the rear barrel portion for directing laser light in a direction toward the front barrel portion; longitudinally movable insert member means for maintaining a means for receiving the laser light in proper proximity to the laser means substantially independent of the longitudinal dimension of the laser light source, the insert member being movably disposed in the rear barrel portion forward of the laser means toward the front barrel portion.
Claim 13
Independent Claim
79 words
A method for connecting an optical fiber to a laser light source comprising the steps of: inserting a ferrule of an optical fiber into a housing having disposed therein the laser light source; securing the ferrule in the housing such that the ferrule is in constant contact with a movable housing membrane such that the ferrule is maintained at a substantially constant distance from the laser light source substantially independent of the longitudinal dimension of the laser light source.
Claim 14
Independent Claim
79 words
A method for connecting an optical fiber to a laser light source comprising the steps of: inserting a ferrule of an optical fiber into a housing having disposed therein the laser light source; securing the ferrule in the housing such that the ferrule is in constant contact with a movable housing membrane such that the ferrule is maintained at a substantially constant distance from the laser light source substantially independent of the longitudinal dimension of the laser light source.
Claim 15
Dependent Claim
21 words
A method in accordance with claim 11, wherein the laser light source is secured in the housing by a press fit.
Claim 16
Dependent Claim
22 words
A method in accordance with claim 11, wherein the ferrule is maintained at a known fixed distance from the laser light source.
Claim 17
Dependent Claim
41 words
A method in accordance with claim 11, wherein the ferrule and the laser light source are maintained in substantial alignment with each other by an insert member movably disposed within the housing, the housing membrane being disposed on the insert member.
