Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an anti-aging cable. Background Art

[0002] It is usually made of several or several groups of wires (at least two in each group) twisted together, similar to a rope. Each group of wires is insulated from each other and are often twisted around a center wire. The entire outside is covered with a highly insulating covering. Cables are mostly used to transmit and distribute electrical energy or transmit electrical signals. Cables are classified according to insulating materials, such as oil-impregnated paper insulated cables, polyvinyl chloride cables, cross-linked polyethylene cables, etc., and are classified according to their uses into power cables, communication cables, and control cables, etc., which are used in power systems, information transmission systems, mechanical equipment, and instrumentation systems, respectively.

[0003] Traditional cables are composed of a core, an insulating layer, a sealing sleeve and a covering layer. Its structural protective layer is not easy to have an anti-aging effect, which can easily shorten the service life of the cable. There is no filler between the internal structures and no anti-extrusion devices are set, which may increase the extrusion inside the cable and damage the cable. It may also easily cause the cable to be squeezed and damaged by external forces. Therefore, technical personnel in this field provide an anti-aging cable to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose an anti-aging cable. The airbag in the middle of the anti-aging cable can increase the resistance when the cable is squeezed, protect the cable and reduce cable damage. The cable is provided with multiple layers of protective layers, and the protective layer material has an anti-aging effect, which increases the service life of the cable, can better protect the cable and reduce resource waste.

[0005] To achieve the above object, the utility model provides the following technical solution: an anti-aging cable, comprising a shell body, eight air bags are evenly and fixedly arranged on the inner side of the shell body, sliding blocks are fixedly arranged on the opposite sides of the eight air bags, coils are fixedly arranged on the inner sides of the eight air bags, and four wires are arranged on the inner sides of the coils;

[0006] The outer shell body comprises an inner protective layer, a waterproof layer is arranged at the lower end of the inner protective layer, a base layer is arranged at the lower end of the waterproof layer, and an outer protective layer is arranged at the lower end of the base layer;

[0007] Through the above technical solution, when the outside of the cable is squeezed, the airbags inside can provide a resistance to reduce the squeezing of the inside of the cable, and when the airbags are squeezed, the sliding blocks between the airbags will slide to support the airbags, helping the airbags to reduce the squeezing and maintain the shape of the airbags, thereby reducing the external squeezing of the wires and protecting the cable. The multiple protective layers provided on the outer shell body work together to protect the cable and reduce the aging speed of the outside of the cable, thereby achieving anti-aging of the cable and increasing the practical life of the cable. The coil can fix the internal wires and cannot be changed at will.

[0008] Furthermore, the inner protective layer includes an insulating layer, and a heat insulation layer is fixedly provided at the lower end of the insulating layer;

[0009] Through the above technical scheme, the insulating layer arranged in the inner protective layer can insulate the electric energy to prevent conduction and also prevent the wire from leaking and causing damage to the outside. The thermal insulation layer can isolate the high temperature from the outside from being transmitted to the inside to cause damage to the wire, and can also isolate the heat emitted by the wire to protect the cable.

[0010] Furthermore, the material used for the waterproof layer is anhydrous calcium chloride;

[0011] Through the above technical solution, anhydrous calcium chloride has strong moisture absorption capacity and a long moisture absorption period, which can keep the interior dry and prevent moisture from damaging the internal structure. It can also be degraded after being discarded and does not pollute the environment.

[0012] Furthermore, a non-slip pad is provided in the middle of the shell body;

[0013] Through the above technical solution, the outer surface of the shell body is relatively smooth and has low friction, and the provision of an anti-slip pad can increase the friction.

[0014] Further, the gap between the sliding block and the airbag is filled with a sponge filler;

[0015] Through the above technical solution, the sponge filler can effectively reduce the gap in the middle and effectively prevent other things from entering therein. The sponge filler is elastic and can reduce the squeezing of the interior, thereby protecting the internal structure.

[0016] Furthermore, the four wires and the coil are filled with rubber fillers;

[0017] Through the above technical solution, the rubber filler can fill the gaps between the wires, and can also protect the four wires from being squeezed, thereby protecting the wires and ensuring that the cable can work normally and preventing damage.

[0018] Furthermore, the material used for the insulating layer is organic silica gel, and the material used for the heat-insulating layer is polyurethane;

[0019] Through the above technical solution, silicone has excellent electrical insulation, voltage resistance, corona resistance and flame retardancy, which can effectively reduce the probability of faults such as short circuits. Polyurethane is a thermal insulation structural material with excellent thermal insulation performance, aging resistance, elasticity, and can effectively protect the internal structure.

[0020] Furthermore, the material used for the outer protective layer is polyvinylidene fluoride;

[0021] Through the above technical scheme, polyvinylidene fluoride has excellent properties such as anti-aging, chemical resistance, weather resistance, and ultraviolet radiation resistance, which can increase the use time and extend the service life.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes an anti-aging cable, in which multiple different types of protective layers adopt different types of materials. The insulating layer made of organic silicone can effectively prevent conductivity and protect the cable. The thermal insulation layer made of polyurethane can well prevent high temperature, has good thermal insulation performance and prevents spontaneous combustion. The specially made external layer has strong anti-aging ability and can be well protected from damage whether it is exposed to wind, sun or soil, thereby increasing the service life.

[0024] 2. The utility model proposes an anti-aging cable, in which eight air bags are arranged between the outer shell body and the coil. The air bags can provide resistance to the cable when it is squeezed, reduce the squeezing of the cable by external forces, reduce the friction inside the cable, and thus protect the internal structure of the cable from damage. The sliding blocks arranged between the air bags can resist the air bags when they are squeezed, maintain the shape of the air bags, reduce the squeezing of the air bags, and protect the cable.
