Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an aluminum core soft cable. Background Art

[0002] Cable, also known as flexible cable, is a cable made of multiple thin copper wires or alloy wires. Compared with hard cables, soft cables have certain flexibility and bendability, and are more suitable for use in situations where movement, bending, or frequent changes of position are required.

[0003] During the use of soft cables, due to their certain softness, most of their surfaces will come into contact with the ground when they are dragged, causing their surfaces to wear and crack easily, thereby reducing their subsequent service life. Utility Model Content

[0004] The utility model aims to provide an aluminum core flexible cable to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum core flexible cable, comprising a cable body, the surface of the cable body is provided with a plurality of wear-resistant sleeves for protecting the outer surface of the cable body, the cable body also comprises a wire core, an insulating layer, a shielding layer, a tensile layer, a wear-resistant layer and an outer sheath, the insulating layer is arranged on the outer surface of the wire core, the shielding layer is arranged on the outer side of the insulating layer, the tensile layer is arranged on the side of the shielding layer away from the insulating layer, the wear-resistant layer is arranged on the other side of the tensile layer, a plurality of elastic rubbers are fixed around the outer side of the wear-resistant layer, and a buffer groove is arranged between adjacent elastic rubbers, and the outer sheath is arranged on the outermost side.

[0006] Preferably, a support plate is provided inside the cable body, and the wire core is arranged on the inner surface of the support plate.

[0007] Preferably, a filling layer is provided between the support plate and the inner side of the insulating layer, and the filling layer is made of glass fiber.

[0008] Preferably, the wear-resistant layer is made of polyurethane, and the tensile layer is made of thermoplastic elastomer.

[0009] Preferably, the shielding layer is made of tin-plated copper.

[0010] Preferably, a plurality of wear-resistant ridges are arranged around the outer surface of the outer sheath, and the wear-resistant ridges are arranged at equal distances.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model has a plurality of wear-resistant sleeves on the surface of a cable body. When the cable body is dragged, the wear-resistant sleeves will first contact the ground, thereby reducing the contact area between the cable body and the ground, thereby preventing the surface from being excessively rubbed. At the same time, a plurality of elastic rubbers are arranged between the wear-resistant layer and the outer sheath, and buffer grooves are formed between adjacent elastic rubbers. When the cable body is subjected to external force, the force can be transmitted to the buffer grooves, and the elastic force of the elastic rubber itself can also keep the cable body from being deformed, thereby extending its service life.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 As shown, an aluminum core flexible cable includes a cable body 1. The surface of the cable body 1 is provided with a plurality of wear-resistant sleeves 2 for protecting the outer surface of the cable body 1. The cable body 1 also includes a core 11, an insulating layer 12, a shielding layer 13, a tensile layer 14, a wear-resistant layer 15 and an outer sheath 16. The insulating layer 12 is arranged on the outer surface of the core 11, the shielding layer 13 is arranged on the outer side of the insulating layer 12, the tensile layer 14 is arranged on the side of the shielding layer 13 away from the insulating layer 12, the wear-resistant layer 15 is arranged on the other side of the tensile layer 14, a plurality of elastic rubbers 3 are fixed around the outer side of the wear-resistant layer 15, and a buffer groove 7 is arranged between adjacent elastic rubbers 3, and the outer sheath 16 is arranged on the outermost side.

[0019] A support plate 5 is disposed inside the cable body 1 , and the wire core 11 is disposed on the inner surface of the support plate 5 , so that the wire core 11 can be auxiliary supported to prevent the wire cores 11 from being squeezed with each other.

[0020] A filling layer 6 is arranged between the support plate 5 and the inner side of the insulating layer 12, and the filling layer 6 is made of glass fiber, so as to fill the gap between the wire core 11 and the insulating layer 12, making the inside of the cable body 1 more round and stable, and avoiding deformation of the cable body 1 due to bending or stretching during use.

[0021] The wear-resistant layer 15 is made of polyurethane, and the tensile layer 14 is made of thermoplastic elastomer, so that the cable body 1 has excellent wear resistance and can effectively absorb and disperse external stress to prevent the cable body 1 from deformation.

[0022] The shielding layer 13 is made of tinned copper, which can shield external electromagnetic signals and facilitate the subsequent use of the cable body 1.

[0023] The outer surface of the outer sheath 16 is surrounded by a plurality of wear-resistant ridges 4 , and the wear-resistant ridges 4 are arranged at equal distances, which can increase the wear resistance with the cable body 1 and thus extend its subsequent service life.

[0024] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0025] Working principle: When in use, when the cable body 1 is dragged at will, a plurality of wear-resistant sleeves 2 are arranged on the surface of the cable body 1, so that the wear-resistant sleeves 2 will contact the ground first, thereby avoiding excessive friction between the surface of the cable body 1 and the ground. At the same time, when the cable body 1 is squeezed by external force, the outer sheath 16 will be subjected to pressure first. Because buffer grooves 7 are arranged between adjacent elastic rubbers 3, the squeezing pressure will convert part of the squeezing force into deformation and transmit it to the inside of the buffer groove 7. At the same time, the elastic force of the elastic rubber 3 itself will also prevent the outer sheath 16 from being deformed.
