FIGS. 7A to 7C schematically show one example of a stopper moving means for moving the stopper 6 in the locking direction or the unlocking direction. The stopper moving means includes a base 10, a driving means (for example, a motor) 11 for the base 10, a pin support 12 provided on the base 10 so as to be able to move forward and backward with respect to the stopper 6, and a pin support. 12, a driving means (for example, a solenoid) 13, a pin 14 fixed to the pin support 12 and inserted into a hole 7 provided in the stopper 6, and a spring 15 for applying a biasing force to the pin support 12. It is configured.

The stopper moving means moves the stopper 6 in the unlocking direction as shown below. For example, as shown in FIG. 7A, the pin 14 of the stopper moving unit is made to face the hole 7 of the stopper 6 to be moved, and then the driving unit 13 is driven to drive the pin supporting member 1.
2 is advanced toward the stopper 6 against the urging force of the spring 15. As a result, as shown in FIG. 7B, the pin 14 is inserted into the hole 7 of the stopper 6.

Thereafter, after it is confirmed by a sensor (not shown) that the pin 14 has been inserted into the hole 7 of the stopper 6, the pin 14 is kept in that state as shown in FIG. The drive unit 11 is driven to displace the base 10 in the direction D in which the stopper 6 is unlocked.

The unlocking operation and the locking operation of the stopper by the stopper moving means are performed by the movement of the pin 14 by the driving means 13 and the displacement of the base 10 by the driving means 11 as described above. Since the operation is performed by two actions, there is a problem that much time is required from the start of the locking release operation or the locking operation of the stopper to the end of the operation.

In the optical switch device, as described above, the connection combination of the fixed-side optical connection component 1 and the movable-side optical connection component 2 is switched.
The unlocking operation and the locking operation of the stopper 6 must be performed. If the unlocking operation and the locking operation of the stopper 6 take time as described above, the optical connection components 1 and It takes a lot of time to switch the combination of the two connections, and there is a problem that it is not possible to meet the demand for reducing the switching time.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a characteristic stopper and a moving means of the stopper in the optical switch device of this embodiment. In the description of this embodiment, the same reference numerals are given to the same parts as those in the conventional example, and the overlapping description of the common parts will be omitted.

In this embodiment, as shown in FIG. 1, the stopper 6 is formed with a gripped portion 18 by bending the distal end side of the stopper 6 main body. This gripped part 1
Numeral 8 is formed so as to protrude from the main body 6a in a direction substantially orthogonal to the stopper locking direction or the locking releasing direction shown in FIG.

The stopper moving means 20 characteristic of this embodiment has a structure capable of moving the stopper 6 in the locking direction or the unlocking direction with only one driving means. . That is, the stopper moving means 20 has a fixed block 21 as shown in FIG. 1, and a driving means (for example, a solenoid) 22 is fixedly provided on the fixed block 21. A movable base 23 is connected to the fixed block 21 via a slider 24. A plunger fixing portion 35 is formed to protrude from an upper end portion of the movable base 23, and the upper end portion of the plunger 22a is connected to the plunger fixing portion 35.

In this embodiment, by supplying power to the driving means 22 to drive the driving means 22,
The plunger 22a is lifted in the upward direction shown in FIG. 1 (in other words, the unlocking direction of the stopper 6), whereby the movable base 23 is pushed up in the unlocking direction of the stopper 6. When the power supply to the driving means 22 is stopped, the plunger 22a is displaced in the downward direction shown in FIG. 1 (in other words, the direction in which the stopper 6 is locked). Displaced in the stopping direction.

A rotary arm 25 is provided on the movable base 23 so as to be rotatable about a rotary shaft 26, and a movable holding portion 27 is formed at the tip end of the rotary arm 25. Have been. As shown in FIG. 1, a fixed-side holding portion 28 is disposed at a position facing the movable-side holding portion 27 with the gripped portion 18 of the stopper 6 interposed therebetween. The fixed side holding portion 28 is connected to the movable base 2 via a fixed arm portion 36.
It is fixed to 3.

A spring mounting portion 30 is formed on the upper portion of the movable base 23 so as to project from a position facing the base end side 25a of the rotating arm portion 25 with a space therebetween. An extended spring 31 is provided between the portion 30 and the base end 25a of the rotating arm portion 25.

The spring 31 exerts a force in a lifting direction as shown by an arrow α in FIG. 1 on the base end 25a of the rotating arm 25 by a restoring force. The rotating arm 25 is rotated in the direction in which the movable holding portion 27 on the distal end side of the
6, the distance between the movable holding portion 27 and the fixed holding portion 28 can be reduced.

In this embodiment, the rotating arm 2
The lower part 5 of FIG. The rotating arm portion push-up portion 32 is fixed to the fixed block 21 via the fixed arm portion 37. When no electric power is supplied to the driving means 22, the rotating arm 25 is locked to the rotating arm push-up portion 32, and the movable holding portion 27 and the fixed holding portion 27 are locked. 28 are configured to be widened.

In this embodiment, a stopper gripping portion is constituted by the spring 31, the rotating arm portion push-up portion 32, the rotating arm portion 25, the movable side holding portion 27, and the fixed side holding portion 28. Have been.

The stopper 6 and the stopper moving means 20 shown in this embodiment are configured as described above. The stopper moving means 20 may be provided in one-to-one correspondence with each of the stoppers 6. However, from the viewpoint of reducing the size and cost of the optical switch device, the stopper moving means 20 is commonly used for a plurality of stoppers 6. 20 is desirably provided.

Hereinafter, an example of the unlocking operation and the locking operation of the stopper 6 by the stopper moving means 20 will be described with reference to FIGS. FIG. 3 is an enlarged view of the stopper 6 and its vicinity.

First, as shown in FIG. 2A, no power is supplied to the driving means 22 (that is, the movable base 23 is located at the lowest position of the set position, and FIG. As shown in FIG.
And the gap between the movable-side holding portion 27 and the fixed-side holding portion 28 is wider than the interval for holding the gripped portion 18 of the stopper 6), and the movable-side holding portion 27 is fixed to the fixed-side holding portion. The position of the stopper moving means 20 is adjusted so that the gripped portion 18 of the stopper 6 to be unlocked is inserted between the portions 28.

Next, the driving means 22 is driven. By the driving of the driving means 22, the plunger 22a is lifted in the upward direction shown in FIG. 2 (the direction in which the stopper 6 is unlocked), whereby the movable base 23 is pushed up as shown in FIG. Displaced in the unlocking direction. Due to the displacement of the movable base 23 and the restoring force of the spring 31, the rotating arm 25 rotates in the direction in which the movable holding portion 27 moves toward the fixed holding portion 28, and the movable holding portion 27 and the fixed holding portion 27 rotate. As the interval between the portions 28 becomes narrower, as shown in FIG. 3B, the gripped portion 18 of the stopper 6 is held between the movable-side holding portion 27 and the fixed-side holding portion 28.

In this embodiment, when the rotary arm 25 is separated from the rotary arm push-up portion 32 by the displacement of the movable base 23, the movable side holding portion 27 and the fixed side holding The portion 28 can hold the gripped portion 18 of the stopper 6.

After the holding portion 18 of the stopper 6 is held between the movable holding portion 27 and the fixed holding portion 28 in this manner, the driving of the driving means 22 is continued, and the movable base 23 is moved. Further, the stopper 6 is displaced in the unlocking direction. As a result, as shown in FIGS. 2C and 3C, the movable-side holding portion 27 and the fixed-side holding portion 28 while holding the gripped portion 18 of the stopper 6 are held.
Is displaced integrally with the movable base 23 in the unlocking direction of the stopper 6, whereby the stopper 6 is lifted, and the unlocking of the stopper 6 is released. By releasing the locking of the stopper 6, as described above, the maintenance of the connection between the fixed-side optical connection component 1 and the movable-side optical connection component 2 is released. For example, the arrangement position of the movable-side optical connection component 2 is changed. Movement is performed.

Thereafter, when the power supply to the driving means 22 is stopped, the movable base 23 is displaced downward (that is, the locking direction of the stopper 6) shown in FIG. As described above, when the movable base 23 starts to be displaced in the locking direction, first, the movable side holding portion 27 and the fixed side holding portion 28 are integrally moved with the movable base 23 in the locking direction of the stopper 6. The movable side holding portions 27 are displaced.
Then, the stopper 6 held by the fixed-side holding portion 28 is displaced in the locking direction and set to the set position. After that, the movable base 23 continues to be displaced in the locking direction of the stopper 6, and the rotating arm 25 is locked to the rotating arm push-up portion 32.

After that, since the movable base 23 continues to be displaced in the locking direction of the stopper 6, the movable holding portion 27 is displaced in the locking direction due to the locking of the rotating arm 25. In contrast to the stop, the fixed-side holding portion 28 continues to be displaced in the locking direction of the stopper 6 with the displacement of the movable base 23, so that the distance between the movable-side holding portion 27 and the fixed-side holding portion 28 is reduced. As a result, the gripping of the gripped portion 18 of the stopper 6 is released.

As described above, in this embodiment, the operation of releasing and locking the stopper 6 by the stopper moving means 20 is performed.

According to this embodiment, the gripper 18 is provided on the stopper 6 and the stopper moving means 20
Is provided with a structure that can perform a series of operations of gripping the gripped portion 18 of the stopper 6 and displacing the stopper 6 in the unlocking direction only by providing one driving means 22. , Since there is no need to provide a plurality of driving means,
The size and cost of the stopper moving means 20 can be reduced, and as a result, the size and cost of the optical switch device can be easily reduced.

Further, since the stopper 6 can be locked or unlocked by continuously driving one drive means 22, the time required for the unlocking or locking operation of the stopper 6 can be reduced. Can be reduced. Specifically, for example, in the configuration of the conventional example shown in FIG. 7, as described above, first, the driving unit 13 is driven to insert the pin 14 into the hole 7 of the stopper 6, and then the driving unit 11 , The two driving means 11 and 13 are driven stepwise, such that the base 10 is moved in the unlocking direction of the stopper 6 to unlock the stopper 6. It takes about 0.5 seconds for the pin insertion operation by the driving means 13 and about 1.5 seconds for the movement of the stopper 6 by the driving means 11 in the second stage. The total time from the start of driving of the drive 13 to the release of the lock of the stopper 6 was about 2 seconds.

On the other hand, in this embodiment, the time from the start of driving of the driving means 22 to the release of the lock of the stopper 6 is about 0.5 seconds, which is the conventional example. It can be seen that the time required for the unlocking operation of the stopper 6 can be significantly reduced as compared with the configuration.

As described above, the time required for releasing and locking the stopper 6 can be drastically shortened, so that the optical connection component 1 on the fixed side and the optical connection component 2 on the moving side can be connected. The switching time can be shortened, and it is possible to sufficiently meet the demand for shortening the switching time of the optical connection.

Further, a sensor for monitoring the operating condition of the driving means is provided in accordance with the number of driving means. In this embodiment, since only one driving means is required, the number of the sensors is reduced. be able to. Thus, the number of components of the optical switch device can be reduced, and the cost of the optical switch device can be further reduced.

Further, as described above, since only one driving means 22 is required, the number of wires for connecting the stopper moving means 20 and a control device for controlling the operation of the stopper moving means 20 is reduced. Can be reduced, and the assembly process of the optical switch device can be simplified. Further, a control configuration for controlling the operation of the stopper moving means 20 can be simplified.

Further, in this embodiment, the gripped portion 18 of the stopper 6 is connected to the movable holding portion 27 and the fixed holding portion 2.
8, the stopper 6 is moved by holding the pin 14 in the hole 7 of the stopper 6 as in the prior art.
, The accuracy of the operation of the stopper moving means 20 can be eased as compared with the configuration in which the stopper 6 is hooked and moved. Thereby, the stopper moving means 20
Can be further simplified. Also,
For example, a sensor that monitors the operation of the stopper moving unit 20 can be a sensor that is cheaper than in the past, so that the cost of the optical switch device can be further reduced.

It should be noted that the present invention is not limited to the above embodiment, but can adopt various embodiments. For example, in the above-described embodiment, the solenoid is used as the driving unit 22, but the driving unit 22 has a configuration capable of selectively moving the movable base 23 in the locking direction and the unlocking direction. The driving means 22 may be constituted by a motor or the like, for example.

As shown in FIG. 4, the arm 103a
The arm 10 extends radially outward from the center along the board surface of the ferrule array board 101,
3b is extended in the radial direction from the outside of the ferrule arrangement board 101 to the inside of the ferrule arrangement board 101.

In the optical switch device 100, the position of the stopper moving means 20 is fixed. When switching the connection between the ferrules 1 and 2, the optical switch device 100 rotates the ferrule array board 101 about the center of the disk to rotate the stopper moving means 20 relative to the ferrule 2 array direction. It is configured to be able to be moved.

Then, the moving ferrule 2 is connected to the arm 1
The ferrule 2 is pulled out from the optical connection component storage section 102 by being gripped by 03a and 103b. Then, the ferrule arrangement board 101 is rotated. At this time, the arms 103a and 103b appropriately transfer the ferrule 2 so that the optical fiber 105 connected to the gripped ferrule 2 does not become entangled with another ferrule 105.

By the rotation of the ferrule array board 101, the moving ferrule 2 gripped by the arms 103a and 103b is made to face the fixed ferrule 1 to be newly connected. The optical connection component storage unit 10 is formed by the arms 103a and 103b.

According to the present invention, only by moving the movable base in the locking direction or the unlocking direction of the stopper,
Stopper moving means is provided which is capable of gripping and moving the stopper in the locking direction or the unlocking direction. Since the stopper moving means only needs to move the movable base in the locking direction or the unlocking direction of the stopper as described above, it is only necessary to provide one driving means. Cost can be reduced. Due to the downsizing and cost reduction of the stopper moving means, downsizing and cost reduction of the optical switch device can be achieved.

Further, as described above, the stopper moving means moves the movable base in one direction, thereby gripping the stopper and moving the stopper in the unlocking direction, or engaging the stopper. Since a series of operations for releasing the grip of the stopper can be performed by moving the stopper in the stopping direction, a plurality of driving means are operated in a stepwise manner to perform the stopper unlocking operation or the stopper locking operation as described above. As compared with the case, the time required for the stopper locking releasing operation and the stopper locking operation can be greatly reduced. Due to this, it is possible to provide an optical switch device that can satisfy the demand for shortening the connection switching time of the optical connection component.

Can be reduced, and the assembly process of the optical switch device can be simplified. Further, the control configuration for controlling the operation of the stopper moving means can be simplified.

The stopper gripping portion has a configuration in which the stopper is moved by sandwiching the gripped portion of the stopper, compared to a configuration in which a pin is inserted into a hole provided in the stopper to hook and move the stopper. Thus, the accuracy of the operation of the stopper moving means can be reduced.
For this reason, since high precision components are not required, inexpensive components can be used, and the cost can be further reduced.

The stopper moving means constitutes a stopper moving means for gripping and moving a selected one of the plurality of stoppers, and means for moving the stopper moving means relatively to the plurality of optical connection parts. In the case where the optical switch device is provided, it is not necessary to provide the stopper moving means in a one-to-one correspondence with each of the plurality of stoppers, so that an increase in the size of the optical switch device can be prevented.
