3 and the locking hole 21 are locked, and the fastener 20 wraps and fixes the cable.

[Problem that the invention seeks to solve]

As described above, in the conventional cable wrapping device 1, the wrapping support 10 and the fastener 20 are configured to form a substantially quadrilateral shape to wrap the cable. However, in this configuration, if the cables are not lined up with an even thickness from the bottom 12 of the containment strut 10 and the fasteners 20 and the bottom 12 are not locked in parallel, some cables may become over-tightened and over-tightened. The disadvantage is that the cables are easily damaged due to the pressure exerted on them, and some cables are not completely secured due to insufficient wrapping force. Furthermore, if the number of cables is small, the cables will not be arranged evenly within the wrapping support 10, making it difficult to work with them, and the cables will be easily damaged as they will be forcefully pressed down by the fasteners 20 in that state.

In particular, fiber optic cables require uniform lateral pressure to prevent cable deformation.

[Means for solving problems]

The cable wrapping device of the present invention has a bottom portion that has a plurality of pairs of through holes spaced equidistant from the center on the inside, on which cables to be wrapped are placed, and a sawtooth-like unevenness on the opposing outer surface that extends from the bottom portion. A U-shaped wrapping post with two arms provided, a flat plate provided with locking holes into which the two arms of the wrapping post are inserted and locked to the sawtooth unevenness, and a A flexible inverted U shape with a spring mechanism in the center and a cross section large enough to connect the top and insert the tip into the through hole in the bottom.
It is characterized in that it is composed of a fastener having a cuff-shaped binding piece.

[Effect]

The cable wrapping device according to the above method involves placing the cable at the bottom of the inner surface of the wrapping post, inserting the tip of the wrapping piece into a pair of through holes that match the thickness of the cable, and inserting the arms into the locking holes. When the flat plate is pressed toward the bottom, the flexible wrapping piece wraps around the cable, and the outer circumference can be pressed almost evenly and fixed.
