Description

Technical Field

[0001] The utility model belongs to the technical field of corrosion resistance of signal cables, in particular to a corrosion-resistant signal cable. Background Art

[0002] Signal cables are often used in a variety of environments, including those exposed to moisture, chemical corrosion, or high salinity (such as oceans and chemical plants). These environmental factors can easily cause corrosion of cable materials, affecting cable performance and lifespan. Corrosion can damage the cable insulation and sheath, leading to signal interference, performance degradation, and even cable failure.

[0003] After searching, in the prior art, Chinese patent announcement number: CN217214242U, authorization date: 2022-08-16, discloses a corrosion-resistant communication cable, including a corrosion-resistant layer, a wire core, a protective layer, a nameplate, a wear-resistant layer, a heat-resistant layer, a polyethylene layer, a carbon fiber layer, a chloroprene rubber layer, an insulating layer and a shielding layer, wherein a wire core is provided inside the protective layer, and the outer surface of the protective layer is fixedly connected to the inner wall of the corrosion-resistant layer, and the corrosion-resistant layer includes a heat-resistant layer, a polyethylene layer, a carbon fiber layer and a chloroprene rubber layer. The corrosion-resistant communication cable, by setting the corrosion-resistant layer and utilizing the cooperation between the polyethylene layer, the carbon fiber layer and the chloroprene rubber layer, can improve the corrosion resistance of this communication cable, so as to avoid the situation that the communication cable is corroded and damaged after long-term use, and can effectively avoid affecting the communication effect. By setting the protective layer and utilizing the cooperation between the shielding layer and the insulating layer, the shielding layer can play a good shielding effect on the signal transmission of the wire core, which is beneficial to the signal transmission of the wire core.

[0004] However, the device still has the following defects: when in use, the cable is dragged on the ground surface and the outer layer of the cable is easily scratched by foreign objects on the ground surface or some objects with sharp thorns, which will cause a short circuit and affect the service life of the cable. The outer layer of the cable is not provided with a waterproof layer. If it is immersed in water for a long time, water will easily enter the inside of the cable. The cable is not provided with a fireproof layer. When a fire occurs, the flame may be transmitted along the cable. There is no pressure-resistant structure inside the cable. When the cable falls from a height, the cable will be damaged. The above will affect the service life of the cable. Utility Model Content

[0005] In response to the above problems, the utility model provides a corrosion-resistant signal cable, including an outer protective sleeve, a spiral sleeve is sleeved on the outer wall of the outer protective sleeve, a galvanized steel mesh is provided on the inner wall of the galvanized steel mesh, a flame retardant and fireproof sleeve is provided on the inner wall of the flame retardant and fireproof sleeve, and a filling sleeve is provided on the inner wall of the flame retardant and fireproof sleeve.

[0006] Furthermore, a waterproof sleeve is provided on the inner wall of the filling sleeve, and several groups of pressure-resistant gaskets are distributed in a circular array on the inner wall of the waterproof sleeve. An outer anti-corrosion sleeve is provided on the central axis of the waterproof sleeve, and the pressure-resistant gasket is installed on the outer wall of the outer anti-corrosion sleeve on the side away from the waterproof sleeve.

[0007] Furthermore, a plurality of groups of cable cores are distributed in a circular array on the inner wall of the outer anti-corrosion sleeve with its own central axis as the center.

[0008] Furthermore, a group of sealing rings are provided at both ends of the spiral sleeve, and the cable inner core includes a cable conductor.

[0009] Furthermore, a semi-conductive insulating sleeve is provided on the outer wall of the cable conductor, and an insulating sleeve is provided on the outer wall of the semi-conductive insulating sleeve.

[0010] Furthermore, a shielding sleeve is provided on the outer wall of the insulating sleeve, and the shielding sleeve is spirally wound on the insulating sleeve.

[0011] Furthermore, a conductor protection sleeve is provided on the outer wall of the shielding sleeve, and an inner anti-corrosion sleeve is provided on the outer wall of the conductor protection sleeve.

[0012] Furthermore, a sealing sleeve is provided on the outer wall of the inner anti-corrosion sleeve, and a synthetic fiber sleeve is provided on the outer wall of the sealing sleeve.

[0013] The beneficial effects of the utility model are:

[0014] 1. The outer protective sleeve of the cable in this device is connected with a spiral sleeve. When the cable is placed, the spiral sleeve will increase the friction, so that the cable will not be easily affected by external factors and slide. At the same time, the gap between each set of spiral leaves of the spiral sleeve also improves the bending flexibility and heat dissipation effect of the cable. The galvanized steel mesh inside the cable increases the internal structural stability of the cable, prevents the internal structure of the cable from being punctured by foreign objects when dragging, and improves the stability of the cable.

[0015] 2. Both the filling sleeve and the outer anti-corrosion sleeve in this device can improve the corrosion resistance of the cable. A waterproof sleeve and a pressure-resistant gasket are added between the filling sleeve and the outer anti-corrosion sleeve. On the premise of anti-corrosion, the cable can also play a waterproof role when soaked in rainwater for a long time. If the cable accidentally falls when installed at high altitude, the pressure-resistant gasket inside the cable can play a buffering role, which can reduce damage to the inside of the cable and increase the pressure resistance of the cable. These four layers of protection significantly improve the safety of the cable, reduce the occurrence of electrical failures, and thus protect the safety of equipment and personnel.
