Description

The present invention relates to a cable such as an optical cable for information communication wired outdoors such as a general residential house, office, factory, or other building in an urban area, or the like, or a cable other than the cable itself. The present invention relates to a cable fastener used for securing or auxiliary retaining.

In general, an aerial optical network using optical cables in urban areas and the like can be installed in a spiral hanger without using a cable ring by placing a steel stranded support wire between utility poles and passing the spiral hanger so that multiple optical cables can be routed. A number of optical cables can be installed in the cable. (For example, see Patent Document 1)
Conventionally, in the post-branch of an optical cable, an aerial closure is inserted at a position that becomes the wiring point of the optical cable, and when the optical cable is inserted into the aerial closure, the optical cable is kept horizontally parallel to the support line. In order to do this, the optical cable is tied with a cable tie string.

In particular, in order to prevent the optical cable from moving from side to side after attaching the aerial closure so that the cable slack is stretched due to the elasticity of the optical cable and the cable mounting part of the closure end face seal is not turned over or misaligned. For this, it is necessary to tie an optical cable to a support line or a suspension line with a cable tie.
For this reason, as shown in FIG. 10, in order to maintain the support line A and the optical cable B stretched between the utility poles D in a horizontal and parallel manner, the front and back of the aerial closure E are bound using a cable tie string C. Has been done. (See Patent Documents 1 and 2)

  However, with this cable tie strap, the cable gripping force is as low as about 5 kgf, and a large gripping force cannot be expected. The cable can be used in response to changes in environmental conditions such as temperature changes and wind pressure load changes. Protection is not fully satisfactory. In addition, it is difficult to attach the cable ties even in the work, and it takes time even for the skilled person, it takes time to remove it, the workability is poor, and the handling is difficult with one hand and can not be done with one hand There is inconvenience. In addition, the cable ties need to be replaced from the service life due to synthetic fiber ropes, etc., and since there is a guarantee of durability strength and installation in the aerial, there are problems in life and reliability, such as deterioration due to the environment such as ultraviolet rays. Due to differences in the tying and fixing due to the difference in the assembly of workers and variations in the construction, there is a disadvantage that it is not uniform and is not satisfactory in terms of reliability.
