Abstract

The male and female parts of a fiber optic (FO) connector are each terminated with a flexible shutter. When the parts are unmated each shutter is closed over the respective end of the FO element, i.e. FO cable and /or bundle, connected to the particular part, and when the parts are inserted for mating the shutters are opened placing the two FO ends in optical communication.

Fiber Optic Connector with Built-in Shutter

The male and female parts of a fiber optic (FO) connector are each terminated with a flexible shutter. When the parts are unmated each shutter is closed over the respective end of the FO element, i.e. FO cable and /or bundle, connected to the particular part, and when the parts are inserted for mating the shutters are opened placing the two FO ends in optical communication.

Molded FO connector's mating male and female parts 1 and 2, respectively, have integrally formed resilient shutters 3 and 4, respectively. In the shown unmated position of the connector shutters 3,4 block light transmission into and/or out of the end of the particular FO element 5 and 6 that terminate in parts 1 and 2, respectively. As the parts 1,2 are advanced toward each other for coupling, cf. arrow A, the tapered end 7 of male part 1 contacts and moves the flap-like shutter 4 of part 2 away from the end of element 6, cf. arrow B, and into the compatibly contoured recess 8 of the tapered inner wall 9 of part 2. Concurrently, as the parts 1 and 2 are so advanced, the cam follower face 10 of the resilient tip shutter 3 of part 1 contacts the cam face 11 of the compatibly contoured recess 12 in wall 9 resulting in shutter 3 being moved away from the end of FO element 5, cf. arrow C, and seated in recess 12 as the parts 1,2 are further advanced towards each other. With part 1 fully inserted into part 2, the connector is mated, the shutters 3 and 4 se...
