Description of the Related Art Conventionally, an optical connector receptacle is mounted on an optical communication device, an optical connector plug is mounted on the optical connector receptacle, and an optical cable connected to the optical connector plug can be connected to and disconnected from the optical communication device. It is configured as follows. Conventionally, a lock mechanism is attached to the optical connector receptacle, and even if the optical connector plug is locked by this lock mechanism and, for example, tension is applied to the optical cable, the optical connector plug does not come off from the optical connector receptacle. .

FIGS. 4 and 5 show an example of the structure of a conventional optical connector receptacle and optical connector plug. 1 in the figure
00 denotes an optical connector receptacle, and 200 denotes an optical connector plug. The optical connector receptacle 100 combines the body halves 101 and 102 having the same shape to form an entire body. When the body halves 101 and 102 are united, the optical fiber support tube 105 is sandwiched between the inner bodies 103 and 104 at the axial center position.
The optical fiber supporting tube 105 supports an optical fiber supporting pin 201 protruding from the optical connector plug 200, and holds the optical fiber supporting pin 201 at the axial center position.

[0004] In this example, the body halves 101 and 102 have a rectangular tube shape. The inner bodies 103 and 104 have a cylindrical shape, and a flat lock plate 1
06 and 107 are formed. Lock claws 106A and 107A are formed inward at the distal ends of the lock plates 106 and 107, and these lock claws 106A and 107A (10 in the illustrated example).
6A) engages with the projection 203 (see FIG. 6) formed on the shell 202 on the optical connector plug 200 side, and prevents the optical connector plug 200 from coming off.

In a state where the lock claw 106A is engaged with the projection 203, even if the optical connector plug 200 pulls the shell 202, the optical cable protective cover 2 connected to the shell 202 will not move.
Even if 04 is pulled, the optical connector plug 200 does not fall out of the optical connector receptacle 100. In order to release this locked state, a lock release operation element 205 is provided outside the shell 202 of the optical connector plug 200. The unlocking operator 205 has a rectangular cylindrical shape, and
Are supported so as to be slidable in the axial direction of the shaft. As shown in FIG. 6, an unlocking cam 206 is protrudingly provided on the distal end side of the unlocking operator 205.
