Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the cord holder of the present invention. FIG. 2 is a sectional view showing another example of the cord holder of the present invention. FIG. 3 is a perspective view showing a state where an optical fiber cord is mounted on the cord holder of the present invention.

1 and 3, reference numeral 1 denotes a holder main body, and the holder main body 1 is provided with two grooves 3 for accommodating an optical fiber cord 2.

The holder main body 1 is formed in a rectangular parallelepiped shape. The holder main body 1 is integrally formed of an elastic soft member such as plastic, soft vinyl chloride, and rubber.

The holder body 1 is provided with two grooves 3, 3 extending along the longitudinal direction of the holder body 1. These grooves 3 and 3 may be provided on the same surface, or may be provided on any separate surface. However, it is preferable to provide them on the same surface as in the illustrated example because the cord can be easily attached and detached. When providing two grooves 3 on the same surface,
As shown in FIG. 1 and FIG.
It is preferable to form the holder main bodies 1 and 4 in such a shape that they are juxtaposed.

The groove 3 is formed of a cord passing portion 3a through which the optical fiber cord 2 passes and a receiving portion 3b for receiving the optical fiber cord 2. The accommodation section 3b is formed in a substantially circular or elliptical cross section. The size of the housing portion 3b is
The diameter of the optical fiber cord 2 is substantially the same or slightly smaller. When the holder body 1 is formed of a soft member such as soft vinyl chloride, as shown in FIG. 2, the size in the direction orthogonal to the insertion direction of the optical fiber cord 2 (the width of the housing portion 3 b) is equal to that of the optical fiber cord 2. It is preferable to form it slightly smaller than the diameter.

The cord passing portion 3a is formed of two parallel inner walls, and the interval between these inner walls (the length between the cord passing portions 3a) is slightly or slightly shorter than the diameter of the optical fiber cord 2 (the cord passing portion 3a). Is spread out by hand).
As shown in FIG. 1, the open end 3c of the cord passing portion 3a may be gradually inclined outward toward the end. Further, the surface (the surface with a groove) 5 of the holder main body 4 in which the groove 3 is provided may be formed so as to be gradually inclined toward the groove 3 as shown in FIG. In this case, the grooved surface 5
And the opening end 3c of the cord passage portion 3a becomes the same.

The grooved surface 5 has an inner surface 5 between the two grooves 3.
The outer surface 5b outside the two grooves 3 and 3 is larger than the groove 3
Is preferably formed high along the depth direction.

A first slit 7 is provided on the surface 6 facing the grooved surface 5 at a central position between the two grooves 3 along the longitudinal direction of the groove 3. Further, it is preferable that a second slit 8 is provided in the center of the two grooves 3 on the grooved surface 5 along the longitudinal direction of the groove 3.

Now, a case where the optical fiber cord 2 is arranged using the holder bodies 1 and 4 will be described. First, one of the pair of two optical fiber cords 2, 2 is inserted into one of the grooves 3 of the holder body 1, and the other one of the optical fiber cords 2 is inserted into the remaining groove 3.

The insertion of the optical fiber cord 2 into the groove 3
The length between the cord passage portions 3a is equal to the length of the optical fiber cord 2.
Is slightly or slightly shorter than the diameter of the optical fiber cord 2, the optical fiber cord 2 is pressed against the open end 3c of the cord passing portion 3a. When the pressed optical fiber cord 2 is pressed (pressed) in the direction of the housing portion 3b, the space between the cord passing portions 3a is expanded, and the optical fiber cord 2 is inserted into the housing portion 3b through the cord passing portion 3a. When the optical fiber cord 2 is inserted into the accommodation section 3b, the length between the cord passing sections 3a returns to the original length shorter than the diameter of the optical fiber cord 2, so that it does not fall out of the accommodation section 3b. When the optical fiber cord 2 is inserted into the groove 3, the optical fiber cord 2 can be easily inserted into the groove 3 if the holder bodies 1 and 4 are made of a soft material. Further, the opening end 3 of the cord passage portion 3a
c is formed so as to be gradually inclined outward toward the end as shown in FIG. 1 or so that the grooved surface 5 is gradually inclined toward the inside of the groove 3 as shown in FIG. By
The insertion of the optical fiber cord 2 into the groove 3 can be performed reliably.

The holder bodies 1 and 4 are formed of a soft member, and the width of the housing portion 3b is adjusted by the optical fiber cord 2.
Since the diameter of the optical fiber cord 2 is slightly smaller than the diameter of the optical fiber cord 2, the holder main body 1 and 4 does not move in the longitudinal direction of the optical fiber cord 2 because the optical fiber cord 2 entering the accommodation part 3b is sandwiched by the accommodation part 3b.

As described above, since the optical fiber cords 2, 2 are merely inserted into the grooves 3, 3 of the holder bodies 1, 4 as shown in FIGS.
2 is not damaged, and the holder bodies 1 and 4 are not entangled with other optical fiber cords 2.

In order to take out the optical fiber cord 2 from the groove 3, if the space between the cord passing portions 3a of the groove 3 is widened by hand, the optical fiber cord 2 comes out from the groove 3, so that the optical fiber cord 2 can be easily attached and detached. At this time, since the holder main bodies 1 and 4 are formed of a soft member, the interval between the cord passing portions 3a can be easily widened, so that the optical fiber cord 2 can be more easily taken out. Also, grooved surface 5
As shown in FIG. 2, the inner surface 5a between the two grooves 3, 3
By forming the outer surface 5b outside the grooves 3 and 3 higher along the depth direction of the groove 3, the cord passing portion 3a
It is easy to widen the interval by hand. Further, the outer surface 5b is
, The gap between the cord passing portions 3a can be easily widened by hand. Further, by providing the first slit 7 on the surface 6 facing the grooved surface 5, it becomes easier to increase the interval between the cord passing portions 3a by hand.

Therefore, the cord holder of the present invention
The pair of two fiber cords 2 can be arranged, and the optical fiber cords 2 can be easily attached and detached.

When the holder main bodies 1 and 4 are formed in a rectangular parallelepiped shape, the surfaces other than the grooved surface 5 become flat, and these surfaces become label attaching surfaces on which labels can be attached. For example,
As shown in FIG. 3, by attaching a label 9 to the surface 6 facing the grooved surface 5, necessary information such as a line number can be written on the label 9. Line identification and identification can be performed reliably. That is, when using a tag or a number tag, the tag or the number tag is entangled with another optical fiber code 2 or a tag to identify a line,
Unable to identify. On the other hand, the holder body 1,
By sticking the label 9 on the plane 4, the tag does not become entangled with the optical fiber cord 2 or the tag, so that the line can be identified and specified reliably. Further, when the number of optical fiber cords 2 is increased, in the case of a bill, the bill becomes difficult to see, and when the number of bills is large, the appearance is poor. On the other hand, in the case of the code holder of the present invention, the label 9 does not become difficult to see and the appearance is good. Also, since the surfaces of the holder bodies 1 and 4 to which the labels 9 are attached are flat, the labels 9
Can be easily attached, and entry into the label 9 after the label is attached can be easily performed.

By providing a slit between the two grooves 3, 3, the pair of optical fiber cords 2, 2 can be divided into two for the holder bodies 1, 4. Specifically, for example, two grooves 3, 3 are formed on the same surface 5, and a second slit 8 is provided between the grooves 3, 3, or the grooved surface 5
By providing the first slit 7 on the surface 6 facing
A pair of optical fiber cords 2 and 2 are attached to holder bodies 1 and 4
Each can be divided into two. Also, the second slit 8
By providing both the first slit 7 and the first slit 7, the pair of optical fiber cords 2, 2 can be more easily divided into two for the holder main bodies 1, 4.

[0023]

As described above, one to two optical fiber cords can be arranged and the cords can be easily attached and detached.
