Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intra-office wiring identification tag in a wiring board of a telephone office or a mounting mechanism thereof, and is used in an environment in which a myriad of communication lines drawn from a large number of communication cables are mixed. Below, it is intended to facilitate reading of an identification symbol attached to an identification tag of an arbitrary communication line (including single-core, multi-core, cord, cable).

[0002]

2. Description of the Related Art A single communication cable contains a large number of communication lines. In particular, in an optical communication cable such as a telephone line, a single optical cable contains 2,000 optical fiber cores. However, the number is expected to reach 4,000 in the near future. In the telephone office, the connector of the terminal is connected to the insertion port of the wiring board in a state where innumerable communication lines drawn from many optical cables are densely mixed vertically and horizontally (see FIG. 7). An identification code (ID code) for identifying a communication line is attached to the optical fiber core wire built in each optical cable. On the other hand, the connection positions of the connectors of the individual optical fiber cores with respect to the wiring board of the central office are frequently changed for various reasons. In this changing work, the ID code is confirmed at the terminal of the optical fiber core. There is a need to. However, the number of optical fibers to be identified is extremely large (2000 as described above).
If the ID code is a one-dimensional identification symbol such as a barcode, the tape on which the ID code is printed must be long, and the tape wound around each optical fiber core is used. It is almost impossible to read the ID code accurately in a state where innumerable communication lines are densely mixed in front, rear, left and right. For this purpose, the ID code is changed to a two-dimensional identification code, and a tag printed with the identification code is attached to each optical fiber core. By the way, the two-dimensional identification symbol is a symbol arranged vertically and horizontally in a range of about 5 mm square and displayed by a combination thereof. The identification symbol printed on the tag is read by a two-dimensional code reader. is there. A commercially available two-dimensional code reader as shown in FIG. 8 is used to read from a position separated by a predetermined distance from the lens at the tip, so that the field of view is several times wider than the size of the tag. On the other hand, since the tags attached to each optical fiber core are densely arranged vertically and horizontally, a plurality of tags enter the field of view of the two-dimensional code reader, or some of the tags to be read are hidden by other tags. It is not easy to read the display of each tag quickly, easily and reliably with a two-dimensional code reader. For the above reasons, for the communication line connected to the wiring board of the central office by a connector, the tag printed with the identification symbol is hung near the terminal connector, and the identification symbol written on this tag is When performing the work of reading with the two-dimensional code reader, for example, it takes 5 seconds to confirm the identification symbol of the tag of one communication line, and it takes a maximum of 5 hours for 4000 communication lines. It becomes a calculation. With the number of communication lines increasing remarkably and wiring change work being done frequently, in order to make wiring change work more efficient and efficient, it is easy and quick to read the identification symbol of each tag with a two-dimensional code reader. There is a strong need to be able to do it accurately.

[0003]

An object of the present invention is to make it possible to freely change an identification symbol display surface of a tag attached to a terminal portion of each communication line so that an identification symbol can be easily, quickly and accurately read. Another object is to devise a tag and a mechanism for attaching the tag to the communication line terminal.

[0004]

Means taken to solve the above problem is that the tag attached near the connector of the communication line has the following elements (a) to (c). (A) The tag has a split-type structure with high shape retention, and the front and back members can be fitted freely. (B) An identification symbol is added to the surface of the front member, and the mating part of the front and back members is added. The tag is fixed to the communication line by forming a straight groove for fitting the communication line into the communication line, and (c) fitting the front and back members together by fixing the communication line in the straight groove. That was to be done.

[0005]

[Operation] If the front and back members are fitted and fixed with the communication line fitted in the straight groove of the mating part of the front and back members, the tag is fixed to the communication line with a predetermined holding force that does not fluctuate. However, since the tag only holds the communication line, the tag can rotate around the communication line and can slide in the axial direction of the communication line. Therefore, the display surface can be easily turned in the reading direction of the two-dimensional code reader by rotating or rotating the tag around the communication line or by sliding the tag. Therefore, even if a large number of tags are complicated, the identification symbol of each tag can be easily and quickly read by the two-dimensional code reader without error.

[0006]

[Embodiment 1] In the above solution, the front and back dividing members of the tag are cylindrical members fitted to each other, and one or both of the circular end faces are provided with the above-mentioned straight grooves.

[0007]

[Operation] Since both front and back divided members are cylindrical members,
The fitting operation is simple, and the fitted state is stable.

[0008]

[Embodiment 2] The front and back divided members of Embodiment 1 are connected by a flexible connecting member.

[0009]

[Operation] Since the front and back splitting members are connected by the above connecting member, the front and back splitting members are not separated from each other. Therefore, it is easy to attach and detach the tag to and from the communication line, which is convenient for handling. is there. In addition, since the connecting member functions as a hinge member, the operation of fitting the back member to the front member is easy by bending the connecting member.

[0010]

[Embodiment 3] In the above solution, both front and back members of the tag are rectangular plate-shaped members, a straight groove parallel to the short side is provided on the back surface of the front member, and a convex portion is provided on the surface of the back member. The front and back members are fixed to each other by fitting the protrusions into the linear grooves.

[0011]

[Operation] Since the tag is rectangular and its display surface has a long diameter, the display area of the tag can be increased without lengthening the straight groove into which the communication line is fitted.

[0012]

Next, an embodiment will be described with reference to the drawings.

[0013]

Embodiment 1 Embodiment 1 is a plastic tag having the structure shown in FIGS. 1 and 2. The front member is a cylindrical member 11 having a T-shaped cross section, and the back member is a cup-shaped member 12 having a U-shaped cross section.
It is what it was. The end faces of the cylindrical portion 11a of the cylindrical member 11 and the end face of the cup-shaped member 12 are provided with linear grooves 13 and 14 in the diametric direction, respectively.
The groove width b of 14 is large enough to press-fit the communication line. The communication line f is fitted into the groove 13 of the cylindrical member 11, and the cup-shaped member 12 is press-fitted and fitted into the cylindrical portion 11a of the cylindrical member 11. At this time, the communication line f is pushed into the linear grooves 13 and 14 and is held between the bottoms of the grooves. Therefore, the communication lines are gripped by the linear grooves 13 and 14 and the cylindrical tag 10 does not move. It is fixed to the communication line f with a certain strength. However, straight groove 1
Since the gripping of the communication line by 3 and 14 is frictional gripping, it is relatively easy to turn the tag around the communication line against this frictional gripping force.

[0014]

Embodiment 2 In Embodiment 2 shown in FIG. 3, both the front and back members 11 and 12 of the tag of Embodiment 1 are connected by a flexible connecting member 15. Front and back members 11, 12 and flexible connecting member 1
Numeral 5 is integrally formed of plastic, and connects the side surface of the disk portion 11 b of the cylindrical member 11 and the lower end side surface of the cup-shaped member 12 by a flexible connecting member 15. In this connection structure, the cup-shaped member 12 is easily fitted to the cylindrical portion 11a of the cylindrical member 11 by inverting the cup-shaped member 12 with the flexible connection member 15 as a hinge.

[0015]

Third Embodiment A third embodiment shown in FIG. 4 corresponds to a relatively thin cylindrical member and cup-shaped member of the first embodiment. The cup-shaped member 42 has a cross-shaped linear groove. No linear groove is provided on the end surface of the cylindrical member 41 (or a concentric small-diameter disk portion may be provided on the back surface of the disk-shaped portion). The cylindrical portion 41a of the cylindrical member 41 is press-fitted into the cup-shaped member 42 with the communication line fitted in one of the cross-shaped linear grooves 44 of the cup-shaped member 42. At this time, the communication line fitted in the straight groove 44 is sandwiched between the bottom of the cup-shaped member 42 and the end face of the cylindrical portion 41a of the cylindrical member 41, whereby the tag is fixed to the communication line. Since the straight grooves are arranged in a cross shape and the tag surface is circular, the mounting direction of the tag with respect to the communication line can be arbitrarily selected every 90 degrees. In this case, the cylindrical member 41 and the cup-shaped member 42 may be connected by a flexible connecting member as in the second embodiment.

[0016]

Embodiment 4 In the embodiment shown in FIG. 5, the front member is a thick disk, and the back member is an inverted T-shaped disk in cross section. The convex portion 52a fitted to the straight groove 54 is provided on the inverted T-shaped disc 52. The specific dimensional relationship of this embodiment is as shown in FIG. 5, for example, the diameter is 8 mm. Straight groove 54 of thick disk
The gap between the bottom of the linear groove 54 and the end face of the projection 52a is 2 mm when the projection 52a of the inverted T-shaped disc 52 is fitted to the
Therefore, when the diameter of the communication line is small, the communication line f may be relatively loosely held in the straight groove by interposing a rubber sheet having an appropriate thickness. However, in the case where the wire diameter of the communication line f is 1.7 mm, 2 mm, or the like, there is no need to use the above rubber sheet when there is no practical problem even if the tag slightly fluctuates with respect to the communication line.

[0017]

Embodiment 5 In the embodiment shown in FIG. 6, the front member is a rectangular thick plate and the back member is a rectangular thin plate.
1 is provided with a straight groove 64 on the back surface, and a convex portion 62 a fitted in the straight groove 64 is provided on the thin plate 62. The specific dimensional relationship of this embodiment is as shown in FIG. 6, for example, the long side of the thick plate is 13 mm and the short side is 6 mm. Thick plate 6
The gap between the bottom of the linear groove 64 and the end face of the convex part 62a may be set to about 2 mm in the state where the convex part 62a of the thin plate 62 is fitted in the one linear groove 64 as in the fourth embodiment.

[0018]

As described above, according to the present invention, the tag is not a conventional flag-shaped tag but a block-shaped tag, which is rotatably attached to the communication line. By rotating the tag appropriately, the display surface of the tag can be easily turned in the direction to approach the two-dimensional code reader, and the tag can be easily moved to a position where the two-dimensional code reader can be easily approached. Each of the innumerable tags of the innumerable tags can be relatively easily and quickly read by the two-dimensional code reader. Therefore, it is possible to efficiently read and check the two-dimensional codes densely attached to a large number of tags.
