High-strength bending-resistant photoelectric composite cable

Abstract

The invention provides a high-strength bending-resistant photoelectric composite cable comprising an optical fiber body, a curved unloading layer, a curved unloading body, movable unloading rods, a unloading dividing ring and an outer protective layer, wherein the surface of the optical fiber body is wrapped with a loose tube, the outer surface of the loose tube is wrapped with an inner water blocking layer, the outer surface of the inner water blocking layer is covered with an inner protective layer, and the outer surface of the inner protective layer is wrapped with an outer water blocking layer. The field high-strength and bending-resistant photoelectric composite cable, which relates to the field of photoelectric composite cables, concentrates the final force center around the outer portion of the optical fiber body and distributes to each of the movable unloading rods by changing the external force direction and unloading force for multiple times, and protects the photoelectric composite cable by combining the loose tube, the inner water blocking layer, the inner protective layer, the outer water blocking layer and the spun yarn, thereby effectively solving the problem that the general photoelectric composite cable is easily bent when subjected to a severe force at certain point when hit by external force, the force bearing points of the photoelectric composite cable are concentrated on one side, and the bending of the photoelectric composite cable causes loss and great influence on information transmission.

Description

technical field [0001] The invention relates to the technical field of photoelectric composite cables, in particular to a high-strength bending-resistant photoelectric composite cable. Background technique [0002] The photoelectric composite cable can transmit audio information with a large capacity and long distance, and this technology has already been used in various fields, especially when the photoelectric composite cable is used in the field, a safe and reliable audio transmission medium is particularly important. The photoelectric composite cable used needs to have a certain ability to resist bending. Because the field environment is more complicated, the photoelectric composite cable is very likely to be locally bent due to collision. The bent photoelectric composite cable will produce a certain loss and cannot be effectively used. Transmission of high-quality information, based on this situation, the development direction of the photoelectric composite cable is mai...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-strength bending-resistant photoelectric composite cable, which solves the problem that the general photoelectric composite cable is prone to bending due to a certain point being severely stressed when it is impacted by an external force. The force point is relatively concentrated, and the bending of the photoelectric composite cable will cause loss, which greatly affects the transmission of information.
