Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a low-noise, low-temperature, and corrosion-resistant flexible cable. Background Art

[0002] Low-noise cables are cables that generate pulse signals less than 5mV under the influence of external factors such as bending, vibration, impact, and temperature changes. They are also called shockproof instrument cables. They are used for measuring tiny signals in many fields such as industry, medicine, and national defense.

[0003] With the improvement of automation level of machinery and equipment in industrial and medical fields, especially in the technical fields of liquid oxygen, liquid nitrogen, liquid hydrogen, ultra-vacuum medical laboratories and other related applications, the functional equipment used in signal transmission, detection and control operation needs to have high stability for power conduction, signal propagation and power safety, especially the requirements for the softness of cables in low temperature environments, the low noise requirements inside the cables during operation, the external anti-interference performance requirements of cables, and the technical requirements of high-end equipment are promoting the research and development and progress in the field of cables. International cable companies have also invested in the research and development of such products.

[0004] For example, the Chinese patent publication number CN218038650U discloses a corrosion-resistant and low-temperature resistant medical-grade cable, including a cable body, the inner side of the cable body is coated with a non-woven fabric, the inner side of the non-woven fabric is coated with a low-temperature resistant strip, conductors are fixedly connected to both sides of the middle of the low-temperature resistant strip, a second corrosion-resistant ring is fixedly installed in the middle of the top of the low-temperature resistant strip, a first corrosion-resistant ring is fixedly installed in the middle of the bottom of the low-temperature resistant strip, a number of evenly distributed low-temperature resistant rings are fixedly connected to the sides of the low-temperature resistant strip, and a number of evenly distributed first filling rings are fixedly connected to the middle of the second corrosion-resistant ring. The utility model is a corrosion-resistant and low-temperature resistant medical-grade cable. By arranging the first corrosion-resistant ring and the second corrosion-resistant ring, the corrosion resistance of the cable body is effectively improved, and by arranging the low-temperature resistant ring and the low-temperature resistant strip, the low-temperature resistance of the cable body is increased, the limitations during use are reduced, and it is more convenient for operators to use.

[0005] Although the above example allows the cable to be used in a low temperature environment, when used in medical equipment, the signal transmission of the medical equipment requires very high precision. During the use of existing cables, the influence of static electricity in the cables causes excessive cable noise, which in turn causes the cables to be affected by noise interference when transmitting signals, resulting in reduced signal transmission accuracy, which causes certain inconveniences in use. At the same time, the surface of the existing cable does not have a hydrophobic function. When liquid splashes onto the cable surface, part of the liquid will adhere to the cable surface, causing the cable surface to be corroded by the liquid and accelerate aging, which causes certain inconveniences in use. Utility Model Content

[0006] The utility model provides a low-noise, low-temperature-resistant and corrosion-resistant flexible cable to solve the problems raised in the above-mentioned background technology.

[0009] A further improvement of the technical solution of the utility model is that: a noise shielding layer is arranged on the inner wall of the ground conductor layer, and a wire rubber is arranged on the inner wall of the noise shielding layer.

[0010] A further improvement of the technical solution of the utility model is that: a conductor is arranged on the inner wall of the wire rubber, and a filling part is overlapped on the surface of the wire rubber.

[0011] A further improvement of the technical solution of the utility model is that the cold-resistant outer rubber layer is made of silicone rubber material with a thickness of 1.5mm-3mm.

[0012] A further improvement of the technical solution of the utility model is that the hydrophobic coating layer adopts nano-particle hydrophobic coating, which is connected to the surface of the cold-resistant outer rubber layer by spraying.

[0013] A further improvement of the technical solution of the utility model is that the noise shielding layer is formed by mutually cross-woven copper wires, and the diameter of the copper wires is 0.05mm-0.1mm.

[0014] A further improvement of the technical solution of the utility model is that the filling part is made of a plurality of hemp ropes with a diameter of 3mm-5mm.

[0015] A further improvement of the technical solution of the utility model is that the wire rubber is made of polyethylene, has a thickness of 0.5mm-1mm, and is eight in number.

[0016] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0017] The utility model provides a low-noise, low-temperature-resistant and corrosion-resistant flexible cable. Through the arrangement of a noise shielding layer, when static electricity is generated during the use of the cable, the generated static electricity is guided under the action of copper wires crisscrossed and braided with each other in the noise shielding layer, so as to prevent the static electricity from entering the conductor and interfering with the transmitted signal. At the same time, under the action of the hydrophobic coating, the liquid splashed onto the surface of the cable is guided to prevent the liquid from adhering to the surface of the cable, which causes the cable to age faster. At the same time, the hydrophobic coating adopts the arrangement of nano-particle hydrophobic coating, and the nano-material also has good antibacterial property, so as to prevent a large number of bacteria from breeding on the surface of the cable, so that the cable is more hygienic and easier to use when used in medical equipment. The cold-resistant outer rubber layer adopts the arrangement of silicone rubber, so that the rubber skin of the cable still has good softness and good corrosion resistance in a low-temperature environment, so that the cable is easier to use. The filling part adopts the arrangement of hemp rope, so as to improve the softness of the cable and increase the tensile strength of the cable, so that the cable is easier to use.
