Abstract

The invention discloses an elastic cable, which comprises three parts, namely an elastic conducting core layer, an elastic insulating layer and metal joints, wherein the elastic conducting core layerand the insulating layer are molded through extrusion systems at the same time; and the metal joints are packaged at two ends of the elastic cable. According to a method, the disadvantage of a lot ofwastes of manpower, time and cost in a traditional casting preparation method is overcome; the elastic cable has the advantages of good molding, high continuous degree and continuous process, massiveproduction can be implemented and the labor cost, the time cost and the production cost are reduced.

Description

technical field [0001] The invention relates to the technical field of flexible electronics, in particular to an elastic cable prepared by extrusion molding. Background technique [0002] With the continuous advancement of science and technology, more and more electronic products are turning to flexibility and customization, such as wearable devices, flexible circuits, antennas, microwave cables, electronic skins, etc. These electronic products not only require the normal operation of electronic components , It is also required that the electronic components can be elastically deformed according to the needs of users, and the connecting cables must also be elastically deformed. Such requirements undoubtedly pose a huge challenge to traditional manufacturing. The relevant research and manufacture of the existing elastic cables is to embed the conductive material into the elastic material by means of a mold and carry out encapsulation and molding. However, there are the follo...
