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 an anti-extrusion signal cable comprising a cable core, an internal protection layer, a shielding layer, an intermediate protection layer, a reinforcing layer, a protection layer and an external protection layer. The cable core comprises an insulator and multiple wire cores. The internal part of the insulator is provided with multiple first through holes and multiple second through holes along an axial direction. Each first through hole is surrounded by 3-6 second through holes. The multiple wire cores are respectively arranged in the multiple first through holes. Each wire core comprises a conductor, a polyester tape which wraps the conductor and a copper wire braiding layer which wraps the polyester tape. The internal part of the internal protection layer is provided with multiple third through holes along the axial direction. The internal part of the intermediate protection layer is provided with multiple fourth through holes along the axial direction. The signal cable has the properties of being waterproof and moisture-proof, flame-retardant and fireproof, anti-interference and anti-extrusion.

Description

technical field [0001] The present invention relates to the related field of communication cables. More specifically, the present invention relates to a crush-resistant 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 ...
