Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a bending-resistant and wear-resistant cable. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer, and are wires that transmit electricity or information from one place to another. Wires and cables are wire products that transmit electrical energy, electrical signals, and realize electromagnetic energy conversion. With the development of science and technology, the application of cables has become more and more extensive, and the environment in which they are located has become more complex and diverse. However, the existing cables are simply protected by short-lived insulating materials such as rubber.

[0003] For example, the Chinese patent: "CN212136016U", the technical solution disclosed in this patent is as follows: a special cable for charging piles, including a cable core layer and a fireproof layer wrapped around the cable core layer; the cable core layer includes a control cable core layer and a charging cable core layer; the control cable core layer is provided with a guide rubber strip, a data transmission cable, a signal control cable, and a first filling layer; the charging cable core layer is provided with a charging cable and a second filling layer; the second filling layer is evenly provided with a plurality of inner cavities for containing fire extinguishing agents; the fireproof layer includes an insulating layer, a shielding layer, a drying layer, a waterproof layer, and a wear-resistant fireproof layer arranged in sequence from the inside to the outside; the wear-resistant fireproof layer is provided with a plurality of convex ends supporting the cables arranged along the circumference of the cable. The utility model has a reasonable structural design, and the bending resistance of the cable is improved by the guide rubber strip, which effectively avoids the bending of the cable. The wear-resistant layer designed with the convex end effectively improves the wear resistance of the cable, and the drying layer with a hygroscopic filling rope effectively dries the cable, thereby improving the safety of the cable.

[0004] However, in actual use, the cable is easily subjected to uneven tension inside and outside the cable due to long-term or frequent bending operations, causing the cable core to twist, shift, or even break. In particular, the cable sheath is prone to breakage, exposing the inner core. Utility Model Content
