A connecting cylinder that can be inserted into the end of another sheath segment is provided at the end of any sheath segment, and the sheath segments and the connecting cylinder are an integral structure made of TPU material.

[0005] As an improvement, the outer wall of the connecting cylinder may preferably protrude from the outer wall of the sheath segment, and the connecting cylinder and the sheath segment are smoothly connected together.

[0006] As a further improvement, an internal thread may be preferably provided on the inner wall of the connecting cylinder, and an external thread may be provided on the outer wall of the other end of the sheath section opposite to the connecting cylinder.

[0007] As a further improvement, when the end of a jacket segment is inserted into the connecting cylinder of another jacket segment, the end of the jacket segment may preferably come into contact with the bottom surface of the inserted connecting cylinder.

[0008] As an improvement, tensile reinforcement ribs may be preferably distributed at intervals within the jacket segment.

[0009] As a further improvement, the cross section of the tensile reinforcement rib may preferably be circular with balanced force.

[0010] As a further improvement, the tensile reinforcement ribs may preferably be a strip structure made of PVC.

[0011] As a further improvement, the tensile reinforcement ribs may preferably be evenly distributed in the jacket section, with six tensile reinforcement ribs in each jacket section.

[0012] As an improvement, the outer wall of the connecting cylinder may preferably be provided with anti-slip protrusions for easy threaded connection.

[0013] As an improvement, the length of the external thread may preferably be smaller than the depth of the connecting cylinder.

[0014] Compared with the existing technology, the advantages of the present invention are: the sleeve structure is adopted, and the number of sheath segments used can be adjusted according to the length of the cable. It is easy to assemble and can cover cables of any length, so that even long wires can be effectively covered, ensuring that the wires are covered, safe to use, and effective. The segmented setting also makes production easier, improves production efficiency, and saves space on manufacturing equipment. After the sheath segment is inserted into the connecting cylinder, it has an interference fit with it. Therefore, the connection between the sheath segment and the connecting cylinder is well sealed, and the overall sealing of the wire sheath is good, which helps to extend the service life of the wire.
