  • Patent number: 9122022
    Abstract: A fiber optic connector has a connector outer housing and a connector inner housing. The connector inner housing has a projection to interact with a latch on an adapter into which the connector is inserted. The force required to move the connector outer housing relative to the connector inner housing is less than the force to remove the connector inner housing from the latch. A groove or opening may also be formed in the connector outer housing to effectively shorten the connector outer housing and prevent interaction of the latch with the outer housing, reducing debris.
