  • Patent number: 9182555
    Abstract: A backplane optical connector includes a first connector secured to a backplane and a second connector mounted on a daughter board. The first connector includes a first optical input-output part, guide holes, and a shutter. The shutter is a plate that covers the first optical input-output part when the daughter board is not inserted. The second connector includes guide pins, a pressing part, and a second optical input-output part. The guide pins first make contact with the first connector and are inserted into the guide holes. The pressing part pivots the shutter after degrees of freedom of the second connector are restricted by the guide pins and the guide holes. There is a space for accommodating the pivoted shutter between the pressing part and the second optical input-output part. The pressing part does not make contact with the first connector until the pressing part makes contact with the shutter.

  • Patent number: 8992097
    Abstract: There is provided an optical connector configured to receive a plurality of MT ferrules attached to terminal ends of multi-fiber cables. The optical connector includes a housing through which multiple receiving holes receiving the MT ferrules are bored. The receiving holes are arranged in the direction of the long side of front end faces of the MT ferrules. A pair of holding elements is provided in each of the receiving holes. The pair of holding elements is positioned at both ends in the direction in which the receiving holes are arranged and protrude to a side at which the MT ferrules are inserted. Both ends of a rear end flange of each of the MT ferrules placed in the receiving holes are held by the pair of holding elements. The optical connector enables easy setting-in of MT ferrules and reduction in size of optical connectors can be achieved.
