[Problems to be solved by the device]

 In the above-mentioned conventional optical fiber cable housing means, in the means shown in FIG. 5, the optical fiber cable is not fixed, so that the optical fiber is not fixed at the time of constructing the end face when attaching the optical plug 34 to the core wire. There is a problem that the fiber cable is easily broken. In addition, there are problems that it is difficult to deliver the optical fiber cable after the end face construction and that the appearance after the delivery is poor. On the other hand, in the means disclosed in Japanese Utility Model Laid-Open No. 59-101207, since it is necessary to provide a dedicated box separately from the box in which the optical communication device is stored, a dedicated space is required and the dedicated box There is a problem that the cost of is extra. Further, in the means disclosed in Japanese Patent Laid-Open No. 3-123303, it is necessary to secure a space for providing a box-shaped case in a box in which the optical communication equipment and the like are stored. And the problem that the number of parts that make up the box-shaped case increases, resulting in higher costs, and the delivery of the part of the optical fiber cable to which the outer coating is attached. Is extremely difficult.

Therefore, in the present invention, an inexpensive clamp having a simple structure is provided in the box in which the optical communication device is housed, so that the optical fiber cable connected to the optical communication device can be easily delivered. It is a technical issue to be solved to make it clean and to prevent breakage at the time of constructing the end face of the optical fiber cable.

[0005]

[Means for Solving the Problems]

 The technical means for solving the above-mentioned problem is to provide an optical fiber cable storage clamp for holding an optical fiber cable which is arranged in a box in which the optical communication device is built and which is connected to the optical communication device. A first support portion that detachably supports the outer coating of the optical fiber cable and a core wire and an inner coating portion of the optical fiber cable are stored in the process of being delivered. A second supporting portion that supports the portion in a detachable state in the process of being drawn is provided.

[0006]

[Action]

 With a plurality of optical fiber cable storage clamps arranged at appropriate positions in a box containing optical communication equipment, the first support part of each clamp is used to cover the outer surface of the optical fiber cable. While supporting that part while supporting the core wire and the inner coating part of the optical fiber cable on the second support part of each clamp, Store the fiber cable.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the overall construction of an embodiment of the present invention. In FIG. 1, an optical fiber cable 3 as shown in FIG. 2 is arranged in a circular shape in a box 2 in which an optical communication device 1 is mounted, and the optical fiber cable 3 is provided. An optical plug 4 is connected to the tip of the. The optical plug 4 is attached to the optical connector 5 of the optical communication device 1. When the optical plug 4 and the optical fiber cable 3 are connected, the inner coating and the core wire 3B are exposed by removing the outer coating 3A of the optical fiber cable 3 from the tip by a required dimension. Then, the optical plug 4 is connected by constructing the end face of the end portion. As described above, at least two or more optical fiber cable storage clamps 6 according to the present invention are provided in the box 2 for storing the optical fiber cable 3 in a circular shape. ing.

FIG. 3 is a perspective view of the optical fiber cable storage clamp 6. The optical fiber cable storage clamp 6 is made of synthetic resin or the like, and an adhesive sheet 7 is attached to the bottom surface of the optical fiber cable storage clamp 6 to fix the optical fiber cable storage clamp 6 to the inner surface of the box 2. If so, the adhesive sheet 7 is attached. The lower right part of the optical fiber cable storage clamp 6 is cut out in a rectangular shape in the drawing, and is formed between the arm 6A of the optical fiber cable storage clamp 6 and the front panel 2A of the box 2. The optical fiber cable 3 is wound in a circular shape while the outer coating 3A of the optical fiber cable 3 is inserted into the void 6S to be delivered. That is, the void 6S corresponds to the first support portion described in the section for the utility model registration claim.

Further, as shown in FIG. 3, on the upper surface of the optical fiber cable storage clamp 6 in the drawing, a groove 6B for inserting the inner coating of the optical fiber cable 3 and the core wire 3B, 6C is formed. That is, the grooves 6B and 6C correspond to the second support portions described in the section of the claim for utility model registration.

FIG. 4 is a perspective view showing a state in which four optical fiber cable storage clamps 6 are fixed to the front panel 2 A of the box 2. Then, as shown in FIG. 1, the optical fiber cable 3 is wound in a circular shape while being inserted into the space 6S and the grooves 6B and 6C of the optical fiber cable storage clamp 6, thereby to form an optical fiber. The fiber cable 3 is delivered.

In the above embodiment, the adhesive sheet 7 is used as a means for attaching the optical fiber cable storage clamp 6 to the front panel 2A of the box 2, but the adhesive sheet 7 is not limited to the screw. You may fix it. Further, various optical fiber cables can be supported by changing the shapes and the numbers of the grooves 6B and 6C. Further, grooves such as the grooves 6B and 6C may be formed instead of the gap 6S in which the outer coating 3A of the optical fiber cable 3 is inserted.

[Effect of the device]

 As described above, according to the present invention, the plurality of optical fiber cable storage clamps are arranged at appropriate positions in the box in which the optical communication device is stored, and the first support portion of each clamp is used. The optical fiber cable is delivered in a circular shape while supporting the outer coating of the optical fiber cable, while the core wire and the inner coating portion of the optical fiber cable are attached to the second support portion of each clamp. Since the optical fiber cable can be delivered in a circular shape while supporting the optical fiber, the following effects can be obtained. (1) Since the optical fiber cable is fixed by the first support portion and the second support portion, it is possible to prevent breakage of the optical fiber cable at the time of constructing the end face of the optical fiber cable. it can. (2) Since the wire can be delivered along the first support portion and the second support portion, the work of delivering the optical fiber cable is easy and the appearance is excellent. (3) There is no need to install a dedicated box for storing the optical fiber cable, and the optical fiber cable storage clamp itself is extremely inexpensive, so the optical fiber cable can be manufactured at a low cost. Can be stored. (4) Since the optical fiber cable can be stored along the inner wall, which can be said to be the dead space of the box for storing optical communication equipment, a special optical fiber cable storage space is secured. You don't have to. (5) Even after the optical fiber cable is stored, it is easy to remove the optical fiber cable.
