Description

Technical Field

[0001] The present invention relates to the technical field of drag chain cables, in particular to a composite easy-to-assemble drag chain cable and a manufacturing process thereof. Background Art

[0002] Drag chain cable is a kind of highly flexible special cable that can move back and forth with the drag chain without being easily worn. It is called drag chain cable, which is also commonly called towing cable or tank chain cable. If the drag chain breaks, its cable also needs to be replaced, because damage caused by excessive stretching is inevitable.

[0003] In the existing drag chain cables, multiple groups of cables are placed inside the drag chain structure as a whole. The cables are mixed and gathered together, and the cables are in contact with each other and are prone to mutual wear. The heat transfer between the cables makes the cable more likely to be damaged. After the cable is damaged, there is a lack of protective partition between the damaged cable and the normal cable, which makes the damaged cable more likely to burn and damage other cables. Moreover, when replacing the damaged cable, it is cumbersome and difficult to operate because the cables are entangled and in contact with each other. Summary of the invention
