  • Patent number: 7762726
    Abstract: A fiber optic connector and a fiber optic adapter are disclosed that are manually connectable and disconnectable with each other by a slideable latching means. The fiber optic connector includes an end defining a plug portion. The plug portion holds a ferrule and also directly engages a port on the fiber optic adapter. The plug portion includes a protrusion which also forms a latch catch. The port of the fiber optic adapter includes a flexible retention latch within a slot. The slot engages the protrusion and thus rotationally aligns the fiber optic connector and adapter. The flexible retention latch snaps into and out of the latch catch when the plug portion of the fiber optic connector is slid into and out of the port of the fiber optic adapter thus providing the slideable latching means. Angled retaining surfaces are provided on the retention latch and the latch catch that engage each other. Angles defining the angled retaining surfaces are chosen to provide desired holding and release characteristics.
