  • Publication number: 20090116794
    Abstract: An assembling jig for assembling an optical connector is provided. The optical connector has a pair of beam portions having elasticity and adapted to hold a ferrule holding an optical fiber. The assembling jig includes a body portion, an optical connector receiving portion movably held by the body portion and adapted to receive the optical connector, a ferrule receiving portion movably held by the body portion and adapted to receive the ferrule, and an abutting portion adapted to abut the pair of beam portions to open the pair of beam portions outward.

  • Patent number: 7507032
    Abstract: In an optical connection component for use in connecting a connection object having a key formed on one side surface thereof, a housing for fitting over the connection object is formed around an optical axis. A shutter member is coupled to the housing and includes a light shielding portion which is elastically deformable and extends across the optical axis. The housing includes a key groove portion for receiving the key and an escape groove portion adapted to receive the light shielding potion in an elastically deformed state.

  • Patent number: 7484898
    Abstract: An optical connector included a ferrule defining an optical axis and a holding member holding the ferrule. The ferrule includes a flange portion having a positioned portion. The holding member includes a first and a second beam portions faced to each other, a third beam portion adjacent to the first and the second beam portions, and a fourth beam portion faced to the third beam portion. At least one of the first and the second beam portions has elasticity. At least one of the third and the fourth beam portions has elasticity. At least one of the first and the second beam portions includes a contacting portion contacted with the flange portion in an optical axis direction and holding the ferrule. At least one of the third and the fourth beam portions includes a positioning portion engaged with the positioned portion to prevent the ferrule from being rotated.

  • Publication number: 20090003775
    Abstract: An optical component is improved in workability during assembly operation thereof and makes it possible to easily position an optical fiber. A first ferrule is press-fitted into one end of a central hole of a connecting member, and a second ferrule is press-fitted into the other end of the central hole of the connecting member. An optical fiber is inserted through the first and second ferrules. A coating which coats an intermediate portion of the optical fiber of an optical fiber cord is accommodated in a communicating portion of the central hole of the connecting member in a manner such that the coating is brought into abutment with the first and second ferrules.
