  • Patent number: 7841776
    Abstract: Circuits, apparatus, and methods that provide a connector system that can supply both power and data to a mobile computing or other type of device using a single connection. Further examples also provide a power and data adapter that can provide power and data to a mobile computing device using a single cable. Further examples provide an easy disengagement when a cable connected to the connector is pulled. One such example provides a magnetic connector that uncouples without binding when its cord is pulled. Another example prevents power from being provided at a connector insert until the connector insert is placed in a connector receptacle.

    Abstract: A clip holds a plurality of optical fibers in an array to be inserted into a fiber optic ferrule. The clip has a base member and a lid to hold the optical fibers therebetween. A stacker block assists in making the array by aligning them in a single plane. The optical fibers are then held in alignment for stripping, cleaving and inserting into the fiber optic ferrule.

  • 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.

  • Patent number: 7758255
    Abstract: A fiber optic connector uses an expanded light beam design in a universal receptacle that couples to a single style of plug on the ends of all harnesses. A single, mirror image socket design is used on bulkhead receptacles or box connections, with which two harness plugs mate. The receptacle uses optical lenses for expanding, collimating, and focusing the beam from the plug terminii. The optical lens may comprise rod lenses, ball lenses, or any other optical component that accomplishes the desired beam manipulation with the required diameters and lengths. The optical components are captured in a sleeve that holds the components, establishes the distance between the plug terminii and the lenses, and provides the alignment needed between the plug ferrules and the optical components.
