Problems solved by technology

[0004] This kind of peripheral protective sleeve is the method used by most cable protection at present, but the material of the cable will harden after the protective sleeve is installed, which will affect the laying of the finished cable
Conversely, if a rigid protective sheath is not used, the cable will often be trampled or squeezed during construction or subsequent use. If it is light, it will be trampled or crushed, and if it is heavy, it may cause The wire core inside is broken, which will make the circuit unable to work normally

Abstract

The invention provides a compression resistant flexible cable and a preparation process thereof. The cable comprises a cable core, an insulating layer, a compression resistant flexible layer, a shielding layer and a protective sleeve, which are sequentially sleeved from inside to outside, the compression resistant flexible layer comprises a compression resistant segment and a flexible segment, which are alternately connected, a length ratio of the compression resistant segment to the flexible segment is 1:0.2-0.3, wherein the compression resistant segment is prepared by laminating a first level skeleton network layer, a buffer compression layer and a second level skeleton network layer, and the flexible segment is prepared from a buffer occlusion layer material and has the same thickness as the compression resistant segment. According to the compression resistant flexible cable provided by the invention, the first level skeleton network layer, the buffer occlusion layer and the secondlevel skeleton network layer are provided, and constituents are reasonably optimized, so that the interlayer bonding and auxiliary support have been well improved, excellent mechanical properties suchas compression resistance, impact resistance, high strength and abrasion resistance or the like are provided for the cable, furthermore, the material has good flexibility and a good flexibility effect during the construction, thereby greatly improving the application efficiency.
