Problems solved by technology

If the flexibility of the cable is improved, although it can be easily damaged in the early installation and transportation process, it cannot meet the rigidity requirements of the cable in the later use process, which will also cause its structure to be destroyed during use, bringing social harm. huge economic loss

Abstract

The invention discloses a flexible cable with variable hardness, which relates to a cable, which includes a support core, a plurality of multi-strand wire cores arranged along its circumference are arranged on the side wall of the support core; A buffer layer is provided, and the buffer layer includes a buffer belt and a foam rubber belt. Several first buffer bags and second buffer bags are arranged in the buffer belt; the first buffer bag is filled with buffer gas; the second buffer bag is filled with phase change material. The buffer layer can improve the rigidity of the cable when the cable is in use, so that the cable can meet the rigidity requirements during use, protect the cable from damage during use, and make the cable flexible when the cable is not in use, so that the cable can be transported, It can bear a certain extrusion force during dragging and installation, and the cables can also adapt to each other during the process of stacking each other, so that the internal structure of the cables will not be rigidly damaged during the process.

Description

technical field [0001] The present invention relates to the technical field of cables, in particular to a flexible cable with variable hardness. Background technique [0002] With the development of society, there are more and more types of cables, and the internal structure of the cable is generally composed of a single or multi-strand core and an insulating layer, and has multiple groups of wires, each group of wires is insulated from each other, often Twisted around a center, the entire outside is covered with a highly insulating covering. Cables can be divided into power cables, communication cables and control cables according to their uses, and are generally used to connect circuits and electrical appliances. [0003] At present, in power transmission, the cables are frequently moved during the process of laying cables, and various extrusions, drags, and twists are performed. The traditional internal wires of the cable are tightly connected. When the external force of...
