Problems solved by technology

During the laying or transmission process, the signal cable is particularly vulnerable to being squeezed and pulled. Once the core wire is broken or broken, it will cause heavy losses. Therefore, the signal cable also needs to have strong compressive and tensile properties

Abstract

The invention discloses a signal cable, which comprises a cable core, an inner protection layer, a shielding layer, a middle protection layer, a reinforced layer, a protective layer and an outer protection layer, wherein the cable core comprises an insulator and a plurality of wire cores; a plurality of first through holes are formed in the insulator along the axial direction; a plurality of ridges are arranged on the surface of the insulator along the axial direction; the plurality of wire cores are placed into the plurality of first through holes respectively; each wire core comprises a conductor, a polyester tape and a copper wire braid layer; the polyester tape coats the conductor; the copper wire braid layer coats the polyester tape; and a plurality of second through holes are formed in the middle protection layer along the axial direction. The signal cable disclosed by the invention has excellent waterproof and damp-proof properties, flame-retardant fireproof properties, anti-interference performance and compression resistance.

Description

technical field [0001] The invention relates to the related field of communication cables. More specifically, the present invention relates to a signal cable. Background technique [0002] With the development and popularization of electronic technology products, signal cable, as a tool for transmitting signals, is a common and indispensable tool in industrial production and daily life. However, some signal cables need to be exposed to the air for a long time and are easily affected by moisture. Therefore, the signal cables need to be waterproof and moisture-proof. And if a fire occurs, the flammable signal cable will soon become a medium for spreading the fire, so the signal cable also needs to have flame-retardant and fire-resistant functions. During the laying or transmission process, the signal cable is particularly vulnerable to being squeezed and pulled. Once the core wire is broken or broken, it will cause heavy losses. Therefore, the signal cable also needs to have...
