[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0017] like Figure 1-3As shown, this utility model provides a technical solution: a multi-layer armored cable, including four conductors 1, each conductor 1 is wrapped with an insulation layer 2. The conductors 1 are copper wires, which enable efficient current transmission, reduce energy loss during transmission, and are not easily broken under bending or twisting conditions, thus ensuring the stability and reliability of the overall cable structure. The insulation layer 2 is a rubber tube, which effectively prevents current from leaking from the conductors 1 into the surrounding environment, ensuring stable transmission of electrical energy or signals inside the conductors 1. The rubber tube is soft and has a certain degree of elasticity, allowing the cable to adapt to various bending and twisting conditions without being easily damaged due to stiffness. The insulation layer 2 is wrapped with an inner sheath 3, which is a polyvinyl chloride tube. The inner sheath 3 is wrapped around the insulation layer 2 and can prevent the insulation layer 2 from being damaged by external pressure, collision, or other mechanical forces. It has good chemical stability and can resist the corrosion of many chemical substances. The inner sheath 3 can prevent chemical substances from penetrating into the insulation layer 2, avoiding problems such as decreased insulation performance due to chemical corrosion.
[0018] The inner sheath 3 is wrapped with a first armor layer 4, which is steel strip armor. Several limiting blocks 5 are fixedly installed on the outer wall of the first armor layer 4. The first armor layer 4 is then wrapped with a second armor layer 6, which is steel wire armor. The first armor layer 6 and the second armor layer 4 are fixedly connected. Several limiting grooves 7 are formed on the inner wall of the second armor layer 6. The positions of the limiting blocks 5 correspond to the positions of the limiting grooves 7, and the limiting blocks 5 are embedded in the limiting grooves 7. The cooperation between the limiting blocks 5 and the limiting grooves 7 makes the connection between the first armor layer 4 and the second armor layer 6 tighter. During cable use, the cable may... When subjected to vibration or slight shaking, the limiting block 5 is embedded in the limiting groove 7, which can prevent the first armor layer 4 and the second armor layer 6 from gradually shifting relative to each other due to these small movements. This ensures that the two armor layers always maintain a relatively fixed position, thereby enhancing the stability of the entire cable structure. The second armor layer 6 is wrapped with an outer sheath 8, which is a neoprene rubber sleeve. The outer sheath 8 is fixedly connected to the outside of the second armor layer 6. The neoprene rubber sleeve has a certain resistance to many chemicals and can prevent the cable from being corroded in environments with corrosive gases or liquids. Several buffer holes 9 are opened inside the outer sheath 8.
[0019] The working principle of this utility model is as follows: When using this cable, electrical energy or signals are transmitted through four copper wire conductors 1. The copper wires have good conductivity, which reduces power loss and is not easy to break, ensuring the stability of the cable structure. The rubber tube insulation layer 2 prevents current leakage and is soft and elastic to adapt to cable bending and twisting. The polyvinyl chloride tube inner sheath 3 prevents the insulation layer 2 from being damaged by mechanical force and chemical corrosion. The first armor layer 4 and the limiting block 5 are engaged with the second armor layer 6 and the limiting groove 7 to prevent relative displacement and enhance cable stability. The neoprene rubber outer sheath 8 resists chemical corrosion. The buffer hole 9 plays a protective role in using this cable.
