As a result, while maintaining the same effect as when the shake preventing material 4 is provided, the dimension (width W) in the vicinity of the tip of the base material 2 is reduced by the amount that the shake preventing material 4 is omitted, and the adapter D is narrowed. Even if it is arranged at a pitch, the optical connector C can be attached to and detached from the adapter D.
[0022]
(Embodiment 3)
A third embodiment of the connector attaching / detaching tool of the present invention will be described in detail with reference to FIG. The basic structure of this tool is the same as that shown in FIGS. The difference is that the connector attaching / detaching tool shown in FIGS. 1 to 3A has two base members 2 joined by a joining member 10, but the tool shown in this embodiment is a single metal as shown in FIG. That is, the pair of base materials 2 is formed by bending the elongated plate material at the center thereof. As in the case of the anti-swaying material 4, the anti-swaying that restricts the orientation of the connector C so that the longitudinal direction of the base 2 and the longitudinal direction of the optical connector C coincide with each other also near the tip of each base 2 shown in FIG. A material 4 is provided. The connector attaching / detaching tool shown in FIG. 5 has an extremely simple structure in the vicinity of the tip of the base material 2, so that the dimensions in the vicinity of the connector attaching / detaching tool are even smaller than the connector attaching / detaching tool shown in FIG.

【The invention's effect】
The connector attaching / detaching tool of the present application has the following effects.
(1) Since a locking rod that locks into the locking hole of the optical connector when the substrate is closed and is released when the substrate is opened is provided, the rod member is operated specially as in the past. There is no need to switch the operation between insertion and removal of the optical connector.
(2) Since an anti-vibration material is provided on the outside of the optical connector to prevent the optical connector from shaking, the optical connector can be inserted straight into the adapter insertion hole or pulled straight out of the insertion hole. .
(3) Since the vibration preventing material can be slid to a position protruding from the front end surface of the optical connector, the optical connector can be stably fixed. In addition, since it is possible to slide backward to the position where the distal end surface of the connector is exposed, the shake preventing member does not get in the vicinity of the adapter. In addition, if such a sliding structure is used to cover the entire circumference of the optical connector, the front end surface of the optical connector attached to the adapter will be exposed to the outside once before the attachment until after the attachment. There is no. Therefore, there is no possibility that the insertion loss increases due to the cord or the like coming into contact with the distal end surface of the optical connector during the mounting operation, the distal end surface being damaged, or dust adhering.
(4) The springs urging the bases facing each other by a spring are moved toward each other to lock the bases into the locking holes of the optical connector. Since the lock is released when it is opened against the bias of the spring, there is no possibility that the lock rod is accidentally released during the operation and the optical connector is dropped. Furthermore, since the optical connector is always held with a constant pressing force, there is no possibility that the optical connector will be damaged by an excessive force.
(5) Since the pair of base materials are formed by bending an elongated plate material, the structure is extremely simple, easy to produce, and low cost.
(6) The optical connector can be attached to and detached from the adapter arranged at a narrow pitch.
