Description

Technical Field

[0001] The present invention relates to the technical field of floating cables, and more specifically, it relates to a floating power cable based on communication engineering. Background Art

[0002] Communication cables are cables for transmitting telephones, telegrams, fax documents, television and radio programs, data, and other electrical signals. They are tools composed of multiple wires for transporting electrical energy or electrical signals. With the continuous progress of society, the use of electrical energy and electrical signals is becoming more and more common, and cables have become an indispensable part of our lives. In waters such as oceans and rivers, due to the rapid development, mechanical equipment is needed, and thus cables are also required for power supply and communication.

[0003] In the prior art, ordinary cables are mostly used for power supply and communication. However, ordinary cables are difficult to support on the water surface, and floating cables are thus applied. However, most of the floating cables in the prior art adopt a common integrated columnar cable structure. Since the number of communication lines and conductive wires inside the communication cable is large, the overall communication cable is relatively thick, which is inconvenient for winding and transportation. At the same time, it is not convenient for the targeted maintenance of the power unit and the communication unit in the later stage. Summary of the Invention

Through the clamping cooperation of two sets of clamping parts with the conductive part and the signal part, and the connection of the connecting part, the assembly of the communication cable is realized. The separately arranged conductive part and signal part replace the traditional integrated cable structure, which is convenient for the targeted maintenance of the power unit and the communication unit in the later stage; through the flat structure setting of the conductive part and the signal part, it is convenient for the winding and transportation of the conductive part and the signal part.
