Description

  The present invention relates to a package for a cable such as an optical fiber cable.

As a cable packing body, there is one in which a cable is housed in a storage container in a state of being wound in an 8-shaped shape (see, for example, Patent Document 1 and Patent Document 2).
In this technique, a cable is wound around a barrel-shaped mandrel so as to draw a figure of 8 while controlling the mandrel rotation speed and the winding pitch to form a hole in one radial direction of the bundle. , Forming a bundle.

  The end of winding of the cable is fixed to a box-shaped storage container such as cardboard for storing the bundle. Further, the box-shaped container is provided with a hole at a position corresponding to the hole, and a cylindrical guide member is inserted into the box-shaped container and the hole of the bundle. Then, the winding start end of the cable is inserted into the guide member and pulled out to the outside of the box-shaped storage container, so that the cable is fed out so as to collapse sequentially from the inner portion of the bundle.

When this technology is used, the cable is wound in the shape of figure 8, so that twisting does not occur when the cable is unwound, and even if the unwinding is stopped, the cable is unwound by inertia like a reel and wound. It is known that it can be fed out without breaking down. For this reason, it is generally used for cables such as LAN cables, optical drop cables, and optical indoor cables.
JP 2001-63784 A U.S. Pat. No. 3,178,130

By the way, when the cable is housed in the box-shaped storage container in such a state that the cable is wound in the shape of figure 8, when the cable once drawn is pushed into the box-shaped storage container again, the cable is entangled in the box-shaped storage container. This causes a problem of bending folds and knots in the cable.
Therefore, the extra length of the cable once pulled out is not pushed into the box-shaped container again, but is cut and discarded, or is fixed to the outside of the box.

  However, if the extra length of the cable is long, it may be 10m or more, and there is a problem in disposing of the cable. When the extra cable length is used again, there is a problem that it cannot be pulled out smoothly.

  This invention is made | formed in view of the above, Comprising: It aims at providing the package body of the cable which can accommodate again the extra length of a cable easily, and can be pulled out still more smoothly.

In order to solve the above-described problems, the invention according to claim 1 is a cable packaging body, a container for accommodating a cable, and a cylindrical cable bundle formed by winding the cable in an 8-shape. A package of cables comprising:
The storage container includes a cable bundle storage unit that stores the cable bundle, and a surplus length storage unit that re-accommodates the surplus length of the cable once drawn from the storage container. An opening for taking in and out the extra length of the cable is provided.

Invention of Claim 2 is the package of the cable of Claim 1, Comprising: The said cable bundle is provided with the guide part which pulls out the said cable to the exterior of a cable bundle accommodating part, The said guide part is the said cable It is installed in the boundary part of a bundle accommodating part and the said extra length accommodating part, It is characterized by the above-mentioned.

  According to the present invention, there is an effect that it is possible to realize a package that can easily store the extra length of the cable again and can be pulled out more smoothly.

Hereinafter, the present invention will be described in detail.
[First Embodiment]
A cable bundle was formed by winding the indoor cable 1 shown in FIG. FIG. 1 is a cross-sectional view of a plane perpendicular to the length direction of the indoor cable 1. As shown in FIG. 1, the indoor cable 1 is generally configured by an optical fiber core wire 11, two tension members 12, and a sheath 13 that collectively covers them.

  Tension members 12 are respectively arranged in the longitudinal direction of the section of the indoor cable 1 so as to be separated from the optical fiber core wire 11. The tension member 12 bears the tension acting on the indoor cable 1. For the tension member 12, for example, a steel wire such as a galvanized steel wire, fiber reinforced plastic (FRP), or the like can be used.

The sheath 13 covers the optical fiber core wire 11 and the tension member 12. For example, a thermoplastic resin such as non-halogen flame-retardant polyolefin can be used. A notch 14 is formed at the center of the sheath 13, and the optical fiber core wire 11 can be easily taken out by breaking the sheath 13 from the notch 14.
The bending rigidity (implemented according to IEC 60794-1-2 E17C, D = 40 mm) of the indoor cable 1 is 92 gf (90.2 cN).

2A and 2B are views showing a cable packaging body 20A according to the first embodiment of the present invention, in which FIG. 2A is a perspective view and FIG. 2B is a cross-sectional view. As shown in FIG. 2, the cable packaging body 20 </ b> A includes a cable bundle 21, a box-shaped container 28, a guide member 29, and the like.

Moreover, since it is preferable to provide a cable storage margin of the same degree as the depth D ′ in order to stably store the extra length of the cable, the diameter of the opening 27 is (W−2 × D ′ (inner dimensions)) or less Preferably there is.

  FIG. 3 is a perspective view of the cable bundle 21. The cable bundle 21 is obtained by winding the indoor cable 1 around a barrel-shaped mandrel (not shown) in a figure 8 shape and then removing it from the mandrel. A hole is formed in the cable bundle 21 by controlling the rotation speed of the mandrel and the winding pitch, and a guide member 29 is attached to the hole after the cable is removed from the mandrel.

A hole through which the guide member 29 is inserted is provided in the boundary portion 28 c of the box-shaped container 28. When the cable bundle 21 is accommodated in the cable bundle accommodating portion 28a of the box-shaped accommodating container 28, the guide member 29 is inserted and accommodated in a hole provided in the boundary portion 28c.
By installing the guide member 29 in the boundary portion 28c as described above, the guide member 29 is installed so as to protrude into the extra length accommodating portion 28b as shown in FIG. It can be set as the structure which does not protrude.
Thereby, even if it arranges the plurality of box-shaped storage containers 28, a clearance gap does not arise and it can convey stably.

  The inner end portion (winding start end) of the indoor cable 1 is inserted into the guide member 29, pulled out from the cable bundle housing portion 28a through the guide member 29, and further from the opening 27 provided in the extra length housing portion 28b. Guided to the outside of the container 28. In this way, by pulling out the indoor cable 1 from the guide member 29, the indoor cable 1 is drawn out so as to collapse sequentially from the inner portion of the cable bundle 21.

Further, when the extra length of the indoor cable once pulled out is accommodated again, a circle is drawn so that the extra length of the indoor cable 1 is accommodated in the extra length accommodating portion 28b in order from the guide member 29 side through the opening 27. The entire length of the cable is accommodated in the surplus length accommodating portion 28b. Then, the end of the cable is fixed to the fastener 25 provided on the guide member 29.
In this way, when the extra length of the cable is drawn out again, the extra length of the cable can be smoothly drawn out from the opening 27, and a new cable can be drawn out from the guide member 29 continuously. As a result, the frequency at which the cable becomes entangled and bending folds and knots are reduced is reduced.
Further, according to the first embodiment, the cable is not easily caught by the guide member 29 in the extra length accommodating portion 28b when the extra length of the cable is taken in and out. Therefore, the width D ′ of the extra length accommodating portion 28b can be reduced, and the box-shaped accommodating container 28 can be made compact.
Furthermore, it is not necessary to open and close the box when the extra length of the indoor cable 1 is accommodated and used again, and the workability is very good.
