Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, in particular to a corrosion-resistant signal transmission cable. Background Art

[0002] Signal cable is a tool for signal transmission. Generally, the signal transmitted by signal cable is very small. In order to avoid signal interference, there is a shielding layer outside the signal cable. The shielding layer of the wrapped conductor is generally conductive cloth, woven copper mesh or copper foil (aluminum). The shielding layer needs to be grounded. External interference signals can be guided into the ground by this layer to prevent interference signals from entering the inner conductor and interfering while reducing the loss of the transmission signal.

[0003] Most of the existing signal transmission cables are directly exposed to the external environment. When water vapor and oxygen in the external environment enter the cable, they will react chemically with it, causing the cable to be corroded. At the same time, the cable is also easily deformed when subjected to physical effects such as external pulling, which together affect the service life of the cable. Utility Model Content

[0020] The cable core 2 includes a cable core body 21 , and an insulating layer 22 is disposed outside the cable core body 21 .

[0021] The rubber sealing layer 5 is made of silicone rubber sealing material and has good sealing performance.

[0022] The waterproof layer 8 is composed of water-blocking yarn, which blocks water vapor. The water-blocking yarn is wrapped around the water-absorbing resin, which absorbs water vapor to improve moisture-proof performance.

[0023] The inner protective layer 9 is made of polyethylene material, and a circle of protrusions is provided on the outer side of the inner protective layer 9. The outer protective layer 10 is made of polyurethane material, and a groove is provided on the inner side of the outer protective layer 10. The protrusions and the grooves are meshed with each other to enhance the stability of the cable.

[0024] Working principle: Filling is set between the aluminum-plastic shielding layer and the outside of the cable core to enhance the firmness of the cable and improve its compressive resistance. The elastic reinforcement ribs can ensure that the cable core is not easily deformed when the cable is squeezed by external force. The aluminum-plastic shielding layer and the metal shielding layer are double-shielded, which enhances the shielding force of the cable and has a good anti-interference effect. The sealing layer composed of silicone rubber sealing material has good sealing. When the cable is in a relatively harsh external environment, the flame retardant fireproof layer can first ensure that the cable is not easily burned. The outer protective layer uses polyurethane material to make the cable have good anti-aging and hydrolysis resistance. The bumps and grooves mesh with each other to ensure the stability of the cable. The outer protective layer and the inner protective layer are filled with anti-corrosion materials to enhance the corrosion resistance of the cable. When water vapor enters the interior of the cable, the water-blocking yarn in the waterproof layer will block the water vapor. The water-absorbing resin wrapped in the water-blocking yarn has excellent water absorption and expansion, and can absorb water vapor.
