[0002] In recent years, with the continuous development of import and export trade, China's port facilities have also ushered in a period of rapid development. The number and types of goods have continued to increase, and the distance that equipment moves has become longer and longer. Since the equipment reels are relatively fixed, how to improve the cable structure and increase the equipment running distance is a new problem faced by cable manufacturers; at the same time, with the continuous improvement of automation and intelligence of mechanical equipment, multiple functional cables are required to be used together. Due to the influence of space and laying factors, during installation, cables are generally placed together. When collecting and releasing the wires, it is easy to cause misalignment and entanglement between the wires, which can easily cause the cables to be torn when collecting and releasing the wires. In order to prevent the cables from jumping at the beginning during installation, they must be laid one by one, resulting in low installation efficiency. At the same time, laying multiple cables takes up a large space. In the case of limited laying space, multiple cables with different performance requirements need to be combined into a composite cable. Utility Model Content
