  • Patent number: 10191223
    Abstract: An optical connector is disclosed. The optical connector provides a first plug, a second plug, a sleeve, a spring, and a shell. The first plug and the second plug jointly rotate without rubbing end surfaces of ferrules thereof. The second plug provides a projection, while, the shell provides a hollow that receives the projection of the second plug. The first plug is pushed against the second plug by the spring put between the first plug and the shell but unable to be detached from the second plug because of the projection of the second plug mated with the hollow of the shell, thereby the ferrules in the respective plugs make physical contact in the respective end surfaces.

  • Patent number: 8894298
    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.
