Description

  The present invention relates to an optical fiber for optical communication in a communication circuit such as information communication wired outdoors such as a house of a general house, an office, a factory, and other buildings in an urban area. It relates to a cable fastener to be stopped.

In general, an overhead optical network using an optical cable in an urban area or the like, an optical cable is inserted into a spiral hanger without using a cable ring by laying a steel stranded wire between telephone poles and passing through a spiral hanger so that multiplexing of the optical cable can be performed. It is a construction method that can lay many articles. (For example, see Patent Document 1)
In this method, branching was only possible after using the extra core length in the aerial closure without taking the extra cable length.
In particular, if an aerial optical network is multiplexed in an urban area as in recent years, the conventional method requires that the cable be replaced when the power pole is moved, and that there is not enough extra core wire due to rear branching. In order to solve this problem, it is necessary to prepare the extra length of the cable in advance.
Conventionally, when a sufficient length of the imaginary core wire is sufficiently obtained, the cable is wound around the connection cable extra length storage. However, as shown in FIG. An L-shaped bracket attached to a telephone pole D with a flexible band H, while fixing one point on the circumference of C to a support line A between telephone poles D with a tie string E and attaching another point to the telephone pole D with a tie string F The method of fixing to the utility pole D using G has come to be used (see, for example, Patent Documents 1 and 2). There is a problem with reliability, and the number of floor mounting brackets and the time required for mounting and handling work are different. Since it is easy to cause cracks, there is no uniformity and it is not satisfactory in terms of reliability.It can not be installed at any position between the poles, it is limited to the vicinity of the pole, and it is difficult to assemble at positions off the pole. There were also drawbacks such as inconvenience due to limitations that could not be achieved.

Prior art document information related to the invention of this application includes the following.

The arm is rotated and displaced along the support plate in consideration of packaging so that it does not get in the way. The assembly work can be performed easily. Can also be provided in an inexpensive form.

  In the cable fastener of the present invention, the cable gripping portion is provided with a mounting piece for pressing the cylindrical elastic gripping member detachably on the cable support plate, and is detachably fixed by a stator. By loosening the extra length of the cable on one or both sides, it is possible to extend the entire length of the winding by simply removing the cable, and to maintain the specified minimum radius of curvature of 300 mm by eliminating bending deterioration of the optical cable core wire, and Can be gripped with a constant gripping force, and when the pulling force of the cable exceeds a certain range, it slides out without being able to withstand the frictional resistance of the elastic gripping member, and does not damage the cable and the core wire. In addition, it is possible to safely cope with the pulling action of the cable and to assure the tensile strength.

  Still further, according to the present invention, the elastic gripping member is formed of a cylindrical synthetic rubber having an insertion hole that comes into contact with the outer peripheral surface of the wiring cable, and a cut for inserting the wiring cable is provided in communication with the insertion hole, The fitting piece is detachably fitted to the grip portion, and the mounting piece has bending supports at both ends of the curved portion, and one of the supports is fitted and supported in an insertion hole formed in the cable support plate. The other support is detachably fixed to the cable support plate by a stator, so that the other cables in the spiral hanger are not damaged. The cable can be gripped with a constant gripping force to accommodate a cable that can be wrapped and that has an extra cable length.

  Moreover, in the cable fastener according to the present invention, the hanger is provided with a fixing portion including a holding piece for receiving a support wire and a fastening screw at a distal end portion, and the hanger is hung detachably from the support wire and held. Therefore, it is possible to assemble at any position between the utility poles, uniform and reliable even if any worker works at the time of assembling, suitable for single work on a bucket car etc., wiring work is also possible It is desirable to be able to store the extra cable length in a form that is easy and can greatly increase the reliability, is easy to handle, and is safe.

  Further, in order to ensure the support of the cable, the present invention provides a pair of brackets at the center of the cable support plate with a space between the brackets, and each bracket is provided with a hook piece so as to be freely rotatable, and the rolled cable is provided. Can be hung on the hook piece to arrange and stop the circumference of the cable winding, supporting the extra length of cable connection distributed to the left and right, making it easier to secure the outer diameter of the minimum radius of curvature for cable winding In addition, it is preferable that the cable also serves as a guide when the cable is extended so as to enhance the safety without damaging the cable.
