Abstract:
1. An optical connector plug which houses an optical connector to be inserted and connected to an adapter and which is to be connected to a receptacle holding the adapter, the optical connector plug comprising: a latch piece formed on a surface of the optical connector, having a front end in an inserting direction toward the adapter as a fixed end and a rear end as a free end, extending so as to depart gradually from the surface, and including at a middle portion a protrusion which protrudes on both sides in a width direction; a clip piece formed on the surface, having a rear end in the inserting direction as a fixed end and a front end as a free end, the free end being placed on the free end of the latch piece; a stopper arranged on a rear end side in the inserting direction of the optical connector and coupled and fixed with the optical connector; a housing which engages with the stopper so as to be displaceable by a predetermined amount in the inserting direction with respect to the stopper and which accommodates the optical connector in an opening section at front in the inserting direction; and a biasing member which biases the stopper rearward in the inserting direction with respect to the housing; wherein the free end of the clip piece is placed on an inclination surface at a front end in the inserting direction of a concave section formed on an inner wall surface of the opening section; the latch piece is, at a time of connection with the receptacle, pushed down by the protrusion being pressed by a pressing section provided to the adapter entering into the opening section, recovers to an original state by the pressing section passing through the protrusion, and is locked to the adapter by the protrusion being placed at an engaging section formed on a far side of the pressing section; and at a time of detachment from the receptacle, the housing is displaced against a biasing force of the biasing member whereby the clip piece together with the latch piece are pushed down by the inclination surface to release a lock to the adapter, and, after release of the lock, the latch piece and the clip piece recover to original states by the stopper being displaced by the biasing force of the biasing member.
