Description

Technical Field

[0001] The utility model relates to the field of photoelectric composite cables, in particular to a photoelectric composite cable for heavy mobile equipment. Background Art

[0002] With the booming communications industry, data services are growing exponentially, and multimedia such as voice, data and images need to be transmitted, so a larger network capacity and wider bandwidth are needed, which requires the use of optoelectronic composite cables, especially optoelectronic composite cables used in heavy mobile equipment. Optoelectronic composite cables are used to transmit control signals. Optoelectronic composite cables are suitable for use as transmission lines in broadband access network systems. They are a new type of access method that integrates optical fiber and power transmission copper wire to solve the problems of broadband access, equipment power consumption and signal transmission. The cables on some current heavy mobile equipment move with the actuators on the equipment, and the cables are continuously bent and twisted, etc. The optical fiber inside the cables needs to withstand long-term bending. In long-term use, the cables will crack or break, thereby exposing the cable core, which can easily cause interruption of signal transmission of the optoelectronic composite cable.

[0003] To solve this problem, patent No. CN202021914789.9 discloses an optoelectronic composite cable for heavy mobile equipment. The guide column in the anti-extrusion device is slidably connected with the fixed column, and the external force of the cable is offset under the reset reaction force of the reset spring, thereby reducing the damage to the inside of the composite cable by the external force. At the same time, the anti-extrusion device also has a certain deformation amount, which is convenient for the bending and stretching of the composite cable, thereby improving the tensile and extrusion resistance of the composite cable, and reducing the possibility of the composite cable breaking or cracking when the heavy mobile equipment is working. The optical cable and the electrical cable are insulated from each other to facilitate signal transmission. The metal braided mesh layer enhances the structural strength of the cable itself, which improves the axial tensile strength and radial impact and bending resistance of the cable, thereby increasing the service life of the cable. The elliptical power cable protective tube has a large deformation space in the radial direction of the cable, and has the best protection effect on the power cable core.

[0004] The optoelectronic composite cable for heavy mobile equipment disclosed in the above patent enhances the structural strength of the cable itself by fixing a metal braided mesh layer inside the cable body. However, when the metal braided mesh layer and the cable body are damaged, they cannot be quickly replaced, and the effect of continuous protection cannot be achieved. Utility Model Content

The left and right sides of the polyethylene spiral wide rope are integrally connected with polyethylene spiral edge rings with edge rubber coating layers, which can fit together without gaps when wrapped, and the protection effect is better, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
