[0008]
【Example】
An embodiment of a connector attaching / detaching tool according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0009]
The connector attaching / detaching tool 1 includes a pair of holding pieces 3 for holding both side surfaces of the optical connector 2, and a lever portion 4 provided integrally with a base end of the holding piece 3 to open and close the holding pieces 3. A pivot 5 serving as a fulcrum when the holding piece 3 is opened and closed; a stopper 6 provided between the holding pieces 3 so as to be able to move back and forth; and a concave groove formed in the stopper 6 for inserting the optical cord 7 therethrough. And a movable shaft portion 9 formed in a rod shape integrally with the stopper portion 6 and extending in the pivot direction, and an end of the movable shaft portion 9 is inserted to hold the movable shaft portion 9 slidably. A holding part 11 having an insertion hole 10 formed therein, a flange 12 protruding from the outer periphery of the movable shaft part 9, and a movable shaft between the flange 12 and the inner part of the insertion hole 10 of the holding part 11. In order to urge the stopper portion 6 in the front direction (tip direction) of the holding piece 3, the stopper portion 6 is provided through the portion 9. A coil spring 13 as an elastic member and the holding piece 3 are formed integrally with each other, and are locked to the flange 12 of the movable shaft 9 so that the movable shaft 9 does not protrude from the insertion hole 10 of the holding unit 11. And a locking arm 15 projecting from both right and left sides of the holding portion 11 and locking to the side surface of the holding piece 3 to limit the opening width of the holding piece 3.
[0010]
When the stopper portion 6 is located at the front (front end side) of the holding piece 3 by the force of the coil spring 13, the holding piece 3 is prevented from being closed, and the tip of the stopper portion 6 is pushed in against the force of the coil spring 13, and the stopper is pressed. When the portion 6 is located at the rear portion (the base end side) of the holding piece 3, the holding piece 3 can be closed. For this reason, the gap on the distal end side of the holding piece 3 is formed narrow so as to contact the side surface of the stopper portion 6, and the interval on the base end side is formed wide to allow the stopper portion 6 to escape. The opening width of the holding piece 3 is limited by the locking arm 15, but the opening width is slightly larger than the width of the optical connector 2, and is set to a size that does not contact the adjacent optical connector 2.
[0011]
To remove the optical connector 2 from the adapter 16, first, the operator searches for the optical code 7 of the target optical connector 2 while looking at the system number displayed on the optical code 7, and inserts the optical code 7 into the guide portion 8 of the stopper portion 6. Then, the connector attaching / detaching tool 1 is moved along the optical cord 7 until the connector attaching / detaching tool 1 comes into contact with the optical connector 2, and when the stopper 6 of the connector attaching / detaching tool 1 reaches the optical connector 2, the distal end face of the stopper 6 is connected to the optical connector 2. The connector attaching / detaching tool 1 is further pressed in a state in which the connector attaching / detaching tool 2 is in contact with the connector 2. Then, the movable shaft part 9 is pulled into the insertion hole 10 of the holding part 11 against the force of the coil spring 13, and the stopper part 6 moves from the front part of the holding piece 3 to the rear part. Thus, the holding piece 3 can be closed by operating the lever portion 4. When the lever 4 is gripped, the holding piece 3 holds the side surface of the optical connector 2, and when the connector attaching / detaching tool 1 is pulled out in this state, the optical connector 2 can be removed from the adapter 16. Thereafter, when the lever portion 4 is opened, the holding piece 3 is opened and the optical connector 2 is detached from the connector attaching / detaching tool 1, and at the same time, the stopper portion 6 returns to the original position by the spring force of the coil spring 13.
[0012]
To connect the optical connector 2 to the adapter 16, the optical cord 7 is inserted through the guide portion 8 of the stopper portion 6, and then the stopper portion 6 is pushed in with a finger, and the lever portion 4 is gripped to hold the optical connector 2 in place. Hold with 3. Then, in this state, the optical connector 2 is inserted into the target adapter 16 and connected.
[0013]
The shape of the optical connector attaching / detaching tool is not limited, and can be appropriately changed without departing from the spirit of the present invention.
[0014]
