Abstract: A connector-incorporating plug contains a connector to be inserted into and connected to an adapter in a receptacle and is connected to the receptacle. The connector-incorporating plug includes a housing that is located at a back-end side of the connector in a direction of insertion, to hold the connector, a spring pressing the housing in the direction of insertion, a holder that is located in front of a flange portion formed on the housing and that is mounted to the housing, and a shell member. The holder is pressed by the spring through the flange portion to butt against a projection formed on the inner wall of the shell member, and is kept there. The housing is movable with respect to the holder only along a first axis orthogonal to the direction of insertion. The holder is movable with respect to the shell member only along a crossing axis.

Abstract: In an optical-connector-incorporating plug accommodating and holding an optical connector in a barrel at a front end thereof and accommodating, in the barrel, an extra length portion of an optical fiber extending from an optical cable to the optical connector, the extra length portion bends as the optical connector is moved toward a back end of the barrel when the optical connector is connected to a mating receptacle; the distance from the position where the optical connector is held to the outer wall of the barrel depends on the direction, among the directions orthogonal to the direction in which the optical connector is moved; and a guide portion guiding the bend of the extra length portion in a direction other than the direction where the distance to the outer wall of the barrel is the shortest is formed in the barrel. The optical-connector-incorporating plug can be reduced in size.

Abstract: A stopper 50 is fixed to an optical connector 10, and the optical connector 10 is accommodated in an opening section 21 of a housing 20. The housing 20 is engaged with the stopper 50 so as to be displaceable with respect to the stopper 50 by a predetermined amount in a direction of inserting the optical connector 10 to a receptacle, and the stopper 50 is biased rearward by a coil spring 40 with respect to the housing 20. The free end of a clip piece 15 is placed on the free end of a latch piece 14 of the optical connector 10, and the free end of the clip piece 15 is placed on an inclination surface 23a at the front end of a concave section 23 formed on an inner wall surface of the opening section 21. At the time of detachment from the receptacle, the housing 20 is displaced in a direction to be pulled out against the biasing force of the coil spring 40. Accordingly, the clip piece 15 and the latch piece 14 are pushed down by the inclination surface 23a to release the lock of the latch piece 14.

Abstract: An optical connector device has a first connector including a ferrule for holding an optical fiber and a guide portion projecting longer than the ferrule. The optical connector device also has a second connector for receiving an end of the ferrule along an optical axis of the optical fiber.

The shutter is movable between a cover position at which the optical axis intersects the cover part and an open position at which the optical axis does not intersect the cover part. The guide portion is operable to move the shutter from the cover position to the open position when the guide portion is received into the receiver.
