[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-house wiring identification tag or a mounting mechanism for a wiring board of a telephone switchboard, and an environment in which innumerable communication lines drawn from many communication cables are mixed. It is possible to prevent the identification tag from being caught by another communication line during the communication line extraction work below, and causing no hindrance to the communication line extraction work.

2. Description of the Related Art A large number of communication lines are built in one communication cable. Especially, in an optical communication cable such as a telephone line, 2000 optical fiber cores (communication lines) are included in one optical cable. Built-in, but in the near future 4000
It is planned to become a book. In a station such as a telephone exchange room, the connector of the terminal is connected to the insertion port of the wiring board in a state in which a myriad of communication lines drawn from a large number of optical cables are closely packed in the vertical and horizontal directions. An optical fiber core wire incorporated in each optical cable is provided with an identification code (ID code) for identifying a communication line. On the other hand, the connection position of the connector of each optical fiber core wire to the wiring board of the telephone exchange or the like is frequently changed for various reasons. In this changing work, the ID code is assigned to the terminal portion of the optical fiber core wire. It is necessary to confirm. Moreover, since the number of optical fiber cores to be identified is extremely large (2000 to 4000 as described above), the ID code is used as a two-dimensional identification code, and the tag printed with this identification code is used for each optical fiber core. Is being attached to. By the way, the two-dimensional identification symbol is displayed by a combination of the symbols arranged vertically and horizontally within a range of about 5 mm square, and the identification symbol printed on the identification tag is read by a two-dimensional code reader. Is. On the other hand, since the identification tags attached to each optical fiber core are densely arranged vertically and horizontally, it is not easy to read the display of each identification tag quickly, easily and surely by a two-dimensional code reader. . Due to the above circumstances, regarding the communication line connected to the telephone exchange by the connector, the tag printed with the identification mark is hung near the connector of the terminal, and the identification mark written on this identification tag is used as the above-mentioned two. It takes, for example, 5 seconds to confirm the identification mark of the tag of one communication line when reading with the dimension code reader. If 4000 communication lines are targeted, it takes a maximum of 5 hours to calculate. Become. Today, where the number of communication lines has increased remarkably and wiring change work is frequently performed, it is easy and quick to read the identification symbols of individual tags with a two-dimensional code reader in order to improve the efficiency and efficiency of wiring change work. And there is a strong demand to be able to do it accurately. In order to meet this demand, an identification tag and a mounting mechanism having the structure shown in FIG. 2 have been proposed. This product has a through-hole 2 on the side surface of an identification tag 1 made of plastic and having a rectangular plate shape (or a disk shape).
The identification tag 1 is attached to the communication line through the communication line 3 through the through hole 2, and the identification tag 1 is arranged in the vicinity of the connector 4 of the communication line. In the state of being connected to the telephone exchange, since there is a constant space between the communication lines in the vicinity of the connector 4, it is possible to easily bring the tip of the two-dimensional code reader close to the identification tag 1 arranged in the vicinity of the connector 4. You can
Therefore, the reading operation of the identification symbol can be easily performed. In the above-mentioned conventional technique, the through-hole 2 is provided so that the identification tag 1 does not slide down from the communication line 3 or rotate on the communication line and the direction thereof is changed so as not to hinder the quick reading of the identification symbol. The communication line 3 is gripped with a predetermined tightening force. On the other hand, since the communication lines are tightly entangled, the identification tag is caught on another communication line during the communication line extraction work, which makes the communication line extraction work troublesome, and the identification tag 1 slips down. Since the orientation of the identification tag is changed by rotating the, the task of reading the identification symbol is troublesome. From the above circumstances, it is required to devise the shape of the identification tag 1 so that the identification tag 1 attached to the communication line 3 can pass through the communication lines entwined without being caught by other communication lines relatively smoothly. To be

[0003]

SUMMARY OF THE INVENTION According to the present invention, the shape of an identification tag is devised so that a solid identification tag having a through hole attached to a communication line can pass through another communication line relatively smoothly. That is the subject.

[0004]

Means for Solving the Problems The measures taken to solve the above problems are that a portion of a solid identification tag having a through hole on the side opposite to the connector is tapered.

[0005]

[ Operation ] By making the portion of the solid identification tag having the through hole opposite to the connector a tapered taper shape,
Easily enters divided is tapered in the identification tag in the meantime the communication line is not involved closely when pulling the communication line, therefore, comparison between the communication line even real identification tag in hardly elastically deformed You can slip through smoothly. Therefore, when the communication line is pulled out from the tightly entwined lines, the tag attached to the communication line is relatively unlikely to be caught by another communication line.

[0006]

The inclination angle of the tapered shape in the solving means is set to 40 to 20 degrees.

[0007]

When the inclination angle of the tapered taper shape is smaller than 20 degrees, the length of the identification tag becomes long, and if the length of the tag is not made long, the display area of the two-dimensional code becomes insufficient. If it is too large, it becomes difficult to interrupt the fineness of the solid identification tag between the wires that are closely entangled, and the above-mentioned action cannot be expected very much.

[0008]

EXAMPLES Next, examples will be described with reference to the drawings.
The identification tag 11 of this embodiment is a solid identification tag made of polyethylene resin and having a rectangular through hole.
The length in the direction of, that is, the length in the front-rear direction is 15.1 m
m, the width in the left-right direction is 6.6 mm, and the thickness is 2 mm. The upper and lower surfaces of the identification tag 11 are flat, and the rear portion is
That is, the left and right side surfaces on the opposite side of the connector 4 are tapered surfaces (slopes) 13. The length L of this inclined surface is 4.8 mm, the inclination angle θ is 30 degrees,
The width of the tip is approximately equal to the outer diameter of the communication line 3.

When the pull-out test was conducted under the condition that the communication lines are relatively tightly entangled, 80% of the communication lines were caught by the above-mentioned conventional identification tags which are not easily elastically deformed . However, the thing of this Example did not catch 100%.
In addition, the movement and rotation of the identification tag attached to the pulled-out communication line had almost no hindrance to the reading operation by the two-dimensional code reader. Regarding the identification tag of this embodiment, the end face on the connector side is formed in a semi-circular shape, but this does not reduce the two-dimensional code display area of the identification tag. This is a device to prevent the tag from getting caught.

Further, the tapered surface 13 does not necessarily have to be a straight line, but may be a gentle arc surface, and this makes the angle between the side surface of the identification tag and the tapered surface a smooth curve. It can be said that it is desirable. Regarding the shape of the identification tag, the cross section of the above embodiment is rectangular, but it may be convex lens or elliptical. The one having a convex lens shape or an elliptical shape in the cross-section is less likely to be caught during both pulling and pulling operations.

[0011]

[Effect] As described above, according to the present invention, the portion of the communication line identification tag (solid identification tag) opposite to the connector is tapered so that the identification tags that are not easily elastically deformed are closely packed. It is easy to slip through the entangled communication lines, and therefore the identification tag attached to the communication line is unlikely to be caught on other communication lines during the communication line extraction work, and the communication line extraction work can be performed smoothly and efficiently. Can be done. In addition, since the identification tags are difficult to get caught, it is relatively unlikely that the identification tags will get caught and misaligned, or the orientation will change due to rotation. It is significantly reduced that it becomes difficult to read the two-dimensional code displayed on the identification tag of the communication line.
