Abstract

A receptacle is provided for receiving a fiber optic connector along an optic axis, the connector including a mating end that terminates an end of an optical fiber. The receptacle includes a housing having an open end for receiving the mating end of the fiber optic connector inserted thereinto on the optic axis. A shutter is mounted on the housing for movement to close and open the open end. The shutter extends across the optic axis when the shutter is closed. The shutter is movable away from the optic axis upon engagement by the inserted mating end of the connector. The shutter includes an outer surface having a recessed area for registry with the terminated end of the optical fiber to protect the fiber end.

Claims

1. A receptacle for receiving a fiber optic connector along an optic axis, the fiber optic connector being of the type which has a forwardly projecting ferrule, comprising:

a housing having an open end for receiving the fiber optic connector inserted thereinto on said optic axis; and

a shutter member pivotally mounted on the housing adjacent to said open end and being pivotally movable to close and open said open end, the shutter member extending across the optic axis when the shutter member is closed, the shutter member being pivotable inwardly away from the optic axis upon engagement by the inserted fiber optic connector, and the shutter member including an outer connector-engaging surface engageable by the connector to pivot the shutter member inwardly, the connector-engaging surface having a recessed area for receiving the forwardly projecting ferrule of the connector.

2. The receptacle of claim 1 wherein said shutter member is generally rectangular.

3. The receptacle of claim 2 wherein said recessed area is generally rectangular.

4. The receptacle of claim 1 wherein said outer surface is stepped to define a radially outwardly facing ledge about at least a top portion of said recessed area.

5. The receptacle of claim 1 wherein said recessed area is provided with a depth slightly less than the distance the ferrule projects from the fiber optic connector.

6. A receptacle for receiving a fiber optic connector along an optic axis, the connector including a mating end that terminates an end of an optical fiber, comprising:

a housing having an open end for receiving the mating end of the fiber optic connector inserted therein on said optic axis; and

a shutter member mounted on the housing for movement to close and open said open end, the shutter member extending across the optic axis when the shutter member is closed, the shutter member being movable inwardly away from the optic axis upon engagement by the inserted mating end of the connector, and the shutter member including an outer connector-engaging surface engageable by the connector to pivot the shutter member inwardly, the connector-engaging surface having a recessed area for registry with the terminated end of the optical fiber to protect the fiber end.

7. The receptacle of claim 6 wherein said shutter member is generally rectangular.

8. The receptacle of claim 6 wherein said outer surface is stepped to define a radially outwardly facing ledge about at least a top portion of said recessed area.
