Cable

Abstract

The invention discloses a cable, which includes two cable cores, the outer surfaces of the two cable cores are respectively coated with inner sheaths, and a connecting ring is integrally connected between the inner sheaths outside the two cable cores. The inner sheath outside the two cable cores and the outside of the connecting ring are covered with a high-temperature-resistant insulating layer, the outside of the high-temperature-resistant insulating layer is covered with a shielding layer, and the outside of the shielding layer is covered with a protective layer. The exterior of the protective layer is covered with a thermosensitive color-changing layer. The advantages of the present invention are: the cable structure of the present invention is simple, effectively improves the tensile performance of the cable core, can effectively ensure that the cable is not easy to soften due to high temperature, prevents breakdown by overloaded current, and can play a role of signal shielding, Avoid interfering with the signal transmission of other signal lines. During use, you can easily know the temperature of the outer surface of the wire according to the color of the thermochromic layer, so that the power can be cut off quickly when the cable is overheated, ensuring safe and convenient use.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] Traditional cable sheathing materials have the disadvantages of poor aging resistance and weather resistance, and short service life. The safety of the cable during use is also another issue. It is easy to cause the cable to overheat due to circuit failure or other reasons. There is no safety guarantee, and safety accidents are prone to occur. Therefore, the present inventors devised a cable. Contents of the invention [0004] The technical problem to be solve...
