When a large number of optical connector adapters are provided in the optical connection unit, the optical connector insertion / extraction tool may erroneously read the ID identification information of another adjacent optical connector adapter. Need to prevent.
As in Patent Document 1, when the identification ID 11 is provided in the immediate vicinity of the edge of the optical connector insertion port 10a of the optical connector adapter 10, the ID identification function unit 2 of the optical connector insertion / extraction tool 1 is substantially in contact with the identification ID 11 If the ID identification information is read as close as possible, even if the optical connector insertion / extraction tool 1 is slightly tilted, there is little risk of erroneously reading the ID identification information of other adjacent optical connector adapters. It is.
However, when the identification ID provided on the optical connector adapter 10 side is provided slightly apart from the edge of the optical connector insertion port 10a, and the ID identification function part of the optical connector insertion / extraction tool is slightly separated from the identification ID. When the ID identification information is read, if the optical connector insertion / extraction tool tilts obliquely, the ID identification information of another adjacent optical connector adapter may be erroneously read.

By the way, as an identification ID provided on the optical connector adapter side, for example, it is conceivable to provide, for each optical connector adapter, an ID identification information transmission unit that emits light including each ID identification information.

Reference numeral 28 denotes an optical fiber cord.

  As shown in FIG. 1, the optical connector insertion / extraction tool 21 includes an operation unit 22, an arm unit 23 extending from the operation unit 22, and a connector holding unit 24 attached to the tip of the arm unit 23. Yes.

As shown in FIG. 2, the arm portion 23 has a rectangular cylindrical shape, and houses a slide member 25 in a slidable manner.
As shown in FIG. 1, the slide member 25 is integrated with a trigger 26 in the operation unit 22. The slide member 25 slides to the operation unit 22 side by pulling the trigger 26, and is illustrated when the trigger 26 is released. Slide to the tip of the tool with the spring force.

The materials such as the operation unit 22, the trigger 26, and the arm unit 23 are not particularly limited, but when they are made of metal, it is preferable to apply a resin coating. Thereby, when operating the optical connector insertion / extraction tool, it is possible to prevent noise from appearing in the ID identification information to the ID identification information receiving unit by touching the metal part with a bare hand.
Further, when each of the parts is made of metal, the metal part may be grounded. Similarly to the above, it is possible to prevent noise from appearing on the ID identification information to the ID identification information receiving unit. In this case, as will be described later with reference to FIG. 10, in the embodiment, the control line of the optical connector insertion / extraction tool 21 is connected to the optical connector insertion / extraction tool USB terminal 69b. Can be applied.

As shown in FIGS. 6 to 9, the connector holding unit 24 holds the surrounding frame portion 30 that surrounds the four directions of the gripped portion of the optical connector 31 and the optical connector 31 disposed in the surrounding frame portion 30. And a movable connector gripping part 32 that can be used.
The surrounding frame portion 30 surrounds the four directions of the gripped portion of the optical connector 25 with four-direction wall portions 30a, 30b, 30c, and 30d, and the one wall portion 30c has an opening over the entire tool longitudinal direction. An opening 30ck is provided. The other wall portion 30d also has an opening 30dk for avoiding interference with the slide member 25 and the connector gripping component 32.
The connector holding portion 24 in the illustrated example includes a main body frame portion 33 and a bottom plate portion 34, and is fixed to the distal end portion of the arm portion 23 with screws 35 and 36, respectively.

The connector gripping component 32 is a substantially plate-like member extending in the longitudinal direction of the arm portion having a key-shaped tip portion 32 a that can be engaged with a recess 31 a on the outer surface of the optical connector 31, and by springs 37 and 38. The optical connector 31 is disposed in contact with the lower surface of the slide member 25 while being biased toward the outer surface (the lower surface in FIG. 6).
The connector gripping component 32 is pushed by the force of the spring 38 when the slide member 25 is retracted to the operation unit 22 side (moved to the left in FIG. 6), and the tip 32 a is brought to the outer surface of the optical connector 31. It moves toward and engages with the recess 31a of the optical connector 31 and presses the optical connector 31 against the inner surface of the surrounding frame 30 as shown in FIG.
The illustrated optical connector 31 is a so-called MU optical connector having a smaller size than the SC optical connector. 31b is a ferrule of the optical connector 31, and 31c is a protective boot.
In the case of an optical connection unit using this MU connector, the distance between the optical connector adapters is usually 5 mm or less, and the optical connection adapters are arranged at high density.

6 and 7, reference numeral 45 denotes an ID identification information transmitter provided on the optical connector adapter side, which is provided for each optical connector adapter and transmits light including ID identification information of each optical connector adapter.
An ID identification information receiving unit 41 that receives light including ID identification information of each optical connector adapter transmitted by the ID identification information transmitting unit 45 is provided at a position recessed from the tip of the bottom plate portion 34 of the connector holding unit 24; and Before that, a cylindrical window 42 in which the reading shaft of the ID identification information receiving unit 41 is aligned with the axis is arranged. The ID identification information receiving unit 41 and the cylindrical window 42 constitute a receiving device 43.
In the embodiment, the ID identification information transmitter 45 includes a light emitting element, and emits pulsed light in a bit pattern that constitutes the ID identification information of each optical connector adapter. The ID identification information receiving unit 41 is a light receiving element such as a photodiode that receives light including ID identification information of each optical connector adapter emitted by the light emitting element. When the ID identification information transmission unit is a barcode, the ID identification information reception unit is an image sensor that records the image data of the barcode. Therefore, the light including the ID identification information is reflected from the surface of the display object including the ID identification information as an image such as a pulsed light emitted by a bit pattern constituting the ID identification information or a barcode. Light.
Even if the tool is slightly inclined, the ID identification information of other adjacent optical connector adapters can be obtained because the ID identification information receiving unit 41 is in the back position and the cylindrical window 42 is disposed in front of it. Light from the transmitter 45 can be prevented from entering the ID identification information receiver 41. Further, it is possible to prevent external light such as illumination from entering.

When the optical connector 31 is inserted into the target optical connector adapter 53 in the optical connection unit 20 using the optical connector insertion / extraction tool 21, the optical connector 31 is held by the connector holding portion 24 of the optical connector insertion / extraction tool 21.
In this case, for example, a thin boot 31c portion of the optical connector 31 is inserted into the surrounding frame portion 30 from the side through the opening 30ck of one wall portion 30c of the surrounding frame portion 30 of the connector holding portion 24, whereby the optical connector 31 The root portion (the gripped portion) can be accommodated in the surrounding frame portion 30. Thus, even if the connector holding part 24 surrounds the optical connector 31 from four directions, the optical connector 31 can be accommodated in the surrounding frame part 30 from the side, and work for holding the optical connector can be performed. Easy.

In this state, as shown in FIG. 6, the slide member 25 is in the advanced position and the connector gripping component 32 is pushed down, and the tip end portion 32 a of the connector gripping component 32 is engaged with the recess 31 a of the optical connector 31. Absent.
Next, when the trigger 26 of the operation unit 22 is pulled, the slide member 25 is retracted, the connector gripping part 32 whose restraint is released is pushed by the force of the spring 38, and the tip end portion 32a is lighted as shown in FIG. The optical connector 31 is pressed against the inner surface of the surrounding frame portion 30 and is engaged with the recess 31 a of the connector 31.
As described above, the configuration in which the optical connector 31 can be gripped by the connector gripping component 32 by operating the operating portion 22 and retracting the slide member 25 is compatible with the configuration of the surrounding frame portion 30 surrounding the four directions of the optical connector 31. Thus, the operation of gripping the optical connector 31 at the connector holding portion 24 is facilitated.

In this state, the gripped optical connector 31 is inserted into the optical connector adapter with the distal end side of the optical connector insertion / extraction tool 21 directed toward the optical connector adapter.
At this time, as shown in FIG. 7, the ID identification information receiving unit 41 receives light including ID identification information of the optical connector adapter from the ID identification information transmitting unit 45 on the optical connector adapter side through the cylindrical window 42. The identification information can be read correctly.
Thus, since the cylindrical window 42 is arranged in front of the ID identification information receiving unit 41 provided in the connector holding unit 24, the ID identification information of other optical connector adapters adjacent to the target optical connector adapter can be obtained. There is little fear of reading.
That is, since the cylindrical window 42 is disposed in front of the ID identification information receiving unit 41, the ID identification information transmitting unit 45 is in a state where the optical connector 31 inserted into the optical connector adapter is gripped by the connector gripping component 32. The ID identification information cannot be read unless the axis transmitting the ID identification information and the axis of the cylindrical window 42, that is, the axis in the reading direction of the ID identification information receiving unit 41 do not substantially match. For this reason, if the tool is tilted beyond the readable angle range, the ID identification information cannot be read, and there is little risk of erroneously reading the ID identification information of the adjacent optical connector adapter 53.
Also, no connector gripping error occurs. That is, from the opposite viewpoint, the fact that the ID identification information has been read means that the optical connector 31 is gripped by the connector gripping component 32. Although the ID identification information is read, it does not occur that the optical connector 31 is not gripped.

Further, since the ID identification information receiving unit 41 is located behind the tip of the connector holding unit 24, it is not necessary to mechanically protect the ID identification information receiving unit 41, and the structure is not unnecessarily complicated.
Further, since the surrounding frame portion 30 of the connector holding portion 24 surrounds the four directions of the gripped portion of the optical connector 31, the optical connector 31 does not rotate while the optical connector 31 is gripped, and the optical connector 31 is stabilized. Can be held firmly. Therefore, the handleability is good and the workability is good.
In the above description, the operation of inserting the optical connector 31 into the optical connector adapter 53 with the optical connector insertion / extraction tool 21 has been described, but the same effect can be obtained when the optical connector 31 is removed from the optical connector adapter 53.
When removing the optical connector 31 from the optical connector adapter 53, the connector holding portion 24 of the optical connector insertion / extraction tool 21 is advanced from the rear position of the protective boot 31c, and the inner surface of the surrounding frame portion 30 is applied to the protective boot 31c. By pushing, it can be surely inserted into the target optical connector without affecting other optical connectors or other optical fiber cords.

Further, they are formed at intervals along the length direction. The ID identification information transmitter 45 is formed of a light emitting element that emits visible light, such as a light emitting diode (LED) or a laser diode (LD), and is attached to each optical connector adapter 53 with the attachment body 62 attached to the connection panel portion 55. The corresponding position, that is, the side of each optical connector adapter 53 is located.

The second extending portion 66 is provided with a connection terminal 68 that can be connected to a connection terminal 67 provided on the connection panel 55.
The connection terminal 68 is electrically connected to the ID identification information transmission unit 45, and when the connection terminal 68 is connected to the connection terminal 67, the connection terminal 68 is connected to the connection terminal 67 based on a signal that passes through the CPU box 69 and the connection panel unit 55.

As shown in FIG. 13, the CPU box 69 includes a connection panel connector 69a for connecting a control line from the connection panel 55, an optical connector insertion / extraction tool USB terminal 69b for connecting a control line of the optical connector insertion / extraction tool 21, and a network. A LAN cable connection terminal 69c connected to the database server and a DC12V power supply terminal 69d.

  Since the attachment body 62 is detachable from the optical connection unit 20, the attachment body 62 can be removed when not required, and there is no problem in connection work or the like.

The ID identification information receiving unit 41 on the optical connector insertion / extraction tool 21 side can send a light reception signal to the verification means 63 by receiving light through the cylindrical window 42.
In the embodiment shown in FIG. 10, the optical connector insertion / extraction tool 21 is connected to the verification means (personal computer) 63 by wire (wired via the CPU box 69), but may be connected to the verification means 63 wirelessly. it can. This further improves workability.
As described above, the ID identification information receiving unit 41 is in a position where the light of the ID identification information transmitting unit 45 can be received through the cylindrical window 42 with the optical connector 31 inserted into the optical connector adapter 43.

  As shown in FIG. 14, the verification unit 63 includes a storage unit 72 in which a database 71 including ID identification information of each optical connector adapter 53 is stored, and a control in which the received light signal is input via a CPU box 69.

When the optical connector 31 is inserted into the optical connector adapter 53 to be connected with the optical connector insertion / extraction tool 21 as described above, the light from the ID identification information transmitter 45 corresponding to the optical connector adapter 53 passes through the cylindrical window 42. It enters the ID identification information receiver 41. The ID identification information receiving unit 41 that has received the light carrying the ID identification information of the inserted optical connector adapter 53 sends the received light signal to the verification means 63 via the CPU box 69.
The collating means 63 can display the ID identification information obtained based on the received light signal on the display unit 74, and can display the ID identification information of the target optical connector adapter in the database 71 on the display unit 74.
For this reason, it is possible to easily confirm that the optical connector adapter 53 to which the optical connector 31 is connected is the target optical connector adapter 53 by collating them.
In addition, the verification means 63 notifies the operator by light or voice when the optical connector adapter 53 to which the optical connector 31 is connected is confirmed to be the target optical connector adapter 53. (Not shown) may be provided.

Further, when the optical connector 31 is extracted from a specific optical connector adapter 53, a signal including ID identification information of the optical connector adapter 53 to be extracted is corresponded to the optical connector adapter 53 by the collating means 63. The ID identification information transmitter 45 is sent to the position where the ID identification information transmitter 45 emits light, and the optical connector insertion / extraction tool 21 causes the optical connector adapter 53 from the position corresponding to the ID identification information transmitter 45 to the optical connector. 21 is extracted.
At this time, the light from the ID identification information transmitting unit 45 is received by the ID identification information receiving unit 41, the received light signal is sent to the verification unit 63, and the optical connector 31 is extracted by the verification operation in the verification unit 63. It can be easily confirmed that the connector adapter 53 is the target optical connector adapter 53.

In the embodiment, a so-called MU connector is assumed as an optical connector to be held by the optical connector insertion / extraction tool. However, for example, an SC connector or other single-core optical connector can be used.
In the present invention, the optical connector refers to a so-called male optical connector, and the optical connector adapter refers to a so-called female optical connector to which the male optical connector is connected.

15 and 16 show another embodiment of the connector holding portion. The surrounding frame portion 30 ′ of the connector holding portion 24 ′ is formed on the wall portion 30b ′ facing the recess portion 31a ′ formed on one side surface (the upper side surface in FIG. 15) of the optical connector 31. A protrusion 30f ′ that can be engaged with 31a ′ is provided. The protrusion 30f ′ is formed by bending a part of the front extension part 30e ′ constituting a part of the wall part 30b ′ of the surrounding frame part 30 ′ so as to protrude. The recess 31 a ′ is provided symmetrically with the recess 31 a on the opposite side with which the tip end 32 a of the cord gripping portion 32 is engaged.
When the optical connector 31 fitted to the optical connector adapter 53 is to be extracted, if the tip of the optical connector insertion / extraction tool 21 is pushed toward the optical connector 31, the protrusion 30 f ′ of the surrounding frame portion 30 ′ becomes the optical connector 31. Since it clicks into the recess 31a ′, it can be confirmed that the optical connector 31 is correctly fitted into the connector holding portion 24 ′.
When inserting the optical connector 31 into the optical connector adapter 53, it can be confirmed that the optical connector 31 has been properly fitted in the same manner even when the optical connector 31 is previously fitted into the connector holding portion 24 ′ of the optical connector insertion / extraction tool 21.
