Abstract

PURPOSE:To execute an appropriate protection and containing of a surplus length by inscribing other circle to a circle having a large radius of curvature, in two guide walls, and containing an optical fiber cable between them. CONSTITUTION:The first guide wall 2 having a suitable radius of curvature R1, and the second guide wall 4 which is inscribed to the first guide wall 2, and has a larger radius of curvature R2 than an allowable minimum radius of curvature of an optical fiber cable 5 are provided on a plate-shaped base material 1. Also, in a part where the first guide wall 2 and the second guide wall 4 contact, a notch part 3 is provided by notching the first guide wall 2 by a suitable length. In this way, even against any surplus length which is generated in the optical fiber cable 5, all the surplus length can be contained and protected without forming the optical fiber cable 5 to the allowable minimum radius of curvature or below for cutting and losing it.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an original fiber cable storage device, and in particular, an original fiber cable storage device suitable for processing and protecting excess length of the original fiber cable and f# in the guiding direction. Regarding.

[Background of the invention]

As shown in Fig. 2, the conventional storage container has only the first guide wall 2 with a radius of curvature R1, so the extra length of the original fiber cable is processed only on the outer periphery of the guide wall 2, so in the worst case 2πR,1 There was a surplus or deficiency in the amount. Unlike conventional signal cables, original fiber cables have a large allowable minimum radius of curvature, making it difficult to process the extra length of 2π 1 in or near the equipment. For this reason, it was necessary to prepare several types of storage containers or to use existing fiber cables.

[Purpose of the invention]

An object of the present invention is to provide a storage device for original fiber cables, which can appropriately protect and store any excess length of original fiber cables, and can also change the direction of the original fiber cables at will. It's about offering something.

SUMMARY OF THE INVENTION The present invention is characterized in that the original fiber cable has a radius greater than or equal to the minimum allowable radius of curvature. At least two or more guide walls are provided, and two guide walls are provided.

Inside, another circle with a large radius of curvature is inscribed as a guide for the four-way fiber cable, with the two curvature radii as the upper and lower limits, and storing the original fiber cable at any radius of curvature between them; It lies in the fact that it can be protected.

[Embodiments of the invention]

The following is part 1 of the present invention! An example will be explained with reference to FIG. 1 and FIG. The flat base material 1 has an appropriate curvature radius ratio of 1.

? 1 guide wall 2 and? A second guide wall 4 is inscribed in the first guide wall 2 and has a radius of curvature R2 larger than the minimum allowable radius of curvature of the original fiber cable 5. Further, at a portion where the first guide wall 2 and the second guide wall 4 contact, the first guide wall 2 is cut out to an appropriate length, and a cutout portion 3 is provided.

With the above configuration, the original fiber cable 5 can be
When changing the direction from point to point B and processing all the remaining length of the original fiber cable 5, the optical fiber cable 5 is clamped by the cable clamp 6.7 at the position corresponding to the point A and the point B. Furthermore, the maximum radius of extra length is 1:L1.
Wrap it around the outer circumference of the guide wall until the remaining length reaches an appropriate length. The remaining length is introduced into the space formed by the first guide wall 2 and the guide wall 4 of the spear 2 through the notch 3 provided in the first guide wall 2, and within the range of the maximum radius ratio 1 and the minimum radius R2. Store it.

Therefore, any excess length generated in the original fiber cable 5 can be stored and protected without making it less than the allowable minimum radius of curvature before the original fiber cable 5 is cut.

Figure 4 is a close-up view of other embodiments, and Figure 3 shows the other embodiments.
Curvature radius ratio 1. A guide bar 13 instead of a guide wall is formed on a circumference 1112 having R2. Depending on the formation interval of the occasion guide shells 16, the cutout portion 5 shown in FIG. 1 may be unnecessary. In the figure, 8 is the clamp 6.7 mounting screw, 9 is the buffer material that protects the original fiber cable,
10 is a protective cover attached to the flat base material 1.

〔Effect of the invention〕

According to the present invention, even if there is any extra length when laying the original fiber cable, it can be stored and protected.(1) The terminal treatment of the original fiber cable can be done at the factory, increasing productivity. improves.

(2) It will be easier to install the F7Y Ibar cable, and it will be possible to shorten the construction period.
