Abstract

An adapter assembly is provided for mating an optical fiber along an optic axis with an associated fiber optic transmission device. The adapter assembly includes a body having an end face for mating with the associated fiber optic transmission device, the end face of the body traversing the optic axis. A movable protective shield is adapted for attachment to the body to cover the end face thereof and prevent ingress of contamination thereinto and to protect operator'"'"'s eyes. The shield includes a diverting surface in alignment with the optic axis to prevent light energy transmitted by the optical fiber from being reflected back toward the fiber.

Claims

1. In a fiber optic component assembly for mating an optical fiber along an optic axis with an associated fiber optic transmission means, the component assembly including

a body having an end face for mating with the associated fiber optic transmission means, the end face of the body traversing said optic axis, and

a movable protective shield adapted for attachment to said body to cover the end face thereof and prevent ingress of contamination thereinto and to protect operator'"'"'s eyes from intensive laser beam,

wherein the improvement comprises

diversion means on said movable protective shield in alignment with the optic axis to prevent light energy transmitted by said optical fiber from being reflected back toward the fiber.

2. In a component assembly as set forth in claim 1, wherein said diversion means comprises a deflecting surface on the movable protective shield extending at an oblique angle with said optic axis.

3. In a component assembly as set forth in claim 2, wherein said movable protective shield is attached to the body by a hinge with a hinge axis spaced from and generally perpendicular to said optic axis.

4. In a component assembly as set forth in claim 3, wherein said oblique angle diverges from the hinge axis away from the end face of the body so that the deflecting surface never is perpendicular to the optic axis as the movable protective shield pivots about the hinge to an open position.

5. An adapter assembly for mating an optical fiber along an optic axis with an associated fiber optic transmission means, comprising:

a fiber optic connector having a housing terminating said optical fiber,

an adapter having a receptacle at one end for receiving the fiber optic connector and an end face at an opposite end that mates with the associated fiber optic transmission means, the end face of the adapter traversing the optic axis;

a protective shield movably attached to the adapter spaced from and generally perpendicular to the optic axis, the shield being adapted to cover the end face of the adapter and prevent ingress of contamination thereinto and to protect operator'"'"'s eyes from intensive laser beam.

6. The adapter assembly of claim 5, wherein the shield includes diversion means in alignment with the optic axis to prevent light energy transmitted by said optical fiber from being reflected back toward the fiber.

7. The adapter assembly of claim 6, wherein said diversion means comprises a deflecting surface on the shield extending at an oblique angle with said optic axis.

8. The adapter assembly of claim 7, wherein said shield is attached to the adapter by a hinge with a hinge axis spaced from and generally perpendicular to said optic axis.

9. An adapter assembly of claim 8 wherein said oblique angle diverges from the hinge axis away from the end face of the adapter so that the deflecting surface never is perpendicular to the optic axis as the shield pivots about the hinge to an open position.

10. An adapter assembly of claim 9 wherein said fiber optic adapter comprises a first connector, and including a second fiber optic connector adapted to be coupled end-to-end with the first connector within the adapter when the shield is in an open position.

11. In an adapter assembly for mating an optical fiber along an optic axis with an associated fiber optic transmission means, the adapter assembly including

a body for mating with the associated fiber optic transmission means, and

a movable protective shield adapted for attachment to the body and extending across the body traversing said optic axis to prevent ingress of contamination into the body and to protect operator'"'"'s eyes from intensive laser beam,

wherein the improvement comprises diversion means on said protective shield in alignment with the optic axis to prevent light energy transmitted by said optical fiber from being reflected back toward the fiber.

12. In an adapter assembly as set forth in claim 11, wherein said diversion means comprise a deflecting surface on the movable protective shield extending at an oblique angle with the optic axis.
