Description

Technical Field

[0001] The utility model relates to the technical field of cable structures, in particular to a cold-proof and wear-resistant cable structure. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It has the characteristics of internal current conduction and external insulation.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: there are a variety of cable structures on the market, but these cable structures generally have low wear resistance. When the outer rubber layer is damaged, the inner fiber braided layer will also be damaged quickly, and it cannot prevent cold and frost, which leads to a decrease in the working efficiency of the cable in a low temperature environment. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a cold-proof and wear-resistant cable structure.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a cold-proof and wear-resistant cable structure, including a reinforced cable core, a plurality of cable wires are distributed on the outer wall of the reinforced cable core, the outer walls of the plurality of cable wires are all covered with insulating sleeves, a high-temperature resistant layer is commonly installed on the outer walls of the plurality of insulating sleeves, a wrapping layer is installed on the outer wall of the high-temperature resistant layer, an insulation layer is fixed on the outer wall of the wrapping layer, and a wear-resistant layer is installed on the outer wall of the insulation layer.

[0006] By adopting the above technical solution, the cable transmits power and information through the cable line during use. In this process, the cable core is strengthened to support the cable, thereby reducing the probability of deformation caused by mutual compression between cables. The insulating sleeve isolates each cable line so that each cable line can operate separately. The high-temperature resistant layer reduces the probability of spontaneous combustion caused by overheating of the cable line during operation, thereby extending the service life of the device. The sheath fixes the shape of the cable and reduces the probability of the cables being too loose. The insulation layer improves the cold resistance of the cable, thereby reducing the probability of the cable's working efficiency decreasing in a low-temperature environment. In addition, the wear-resistant layer reduces the probability of skin damage to the cable.

[0007] Furthermore, a protective layer is fixedly arranged on the outer wall of the thermal insulation layer, and a second insulating layer is sleeved on the outer wall of the protective layer.

[0008] By adopting the above technical solution, the second insulating layer isolates the signal outside the cable, thereby reducing the probability of the cable being disturbed during operation.

[0009] Furthermore, a braided layer is installed between the wear-resistant layer and the second insulating layer, the braided layer and the second insulating layer are fixed to each other, and the braided layer is a braided layer made of nylon material.

[0010] By adopting the above technical solution, the braided layer made of nylon material has the advantages of high strength, self-lubrication, wear resistance, etc., which can effectively avoid the probability of internal damage to the cable when the wear-resistant layer is damaged, thereby extending the service life of the cable.

[0011] Furthermore, the protective layer is a protective layer woven from copper wires.

[0012] By adopting the above technical solution, the protective layer woven from copper wires has an anti-interference function, which reduces the probability of the electromagnetic field affecting the cable, thereby reducing the probability of the cable being affected.

[0013] Furthermore, the insulating sleeve is an insulating sleeve made of PVC material, and the second insulating layer is a second insulating layer made of PVC material.

[0014] By adopting the above technical solution, the PVC material has the advantages of light weight, strong corrosion resistance and good insulation performance, thereby reducing the probability of short circuit in the cable during use.

[0015] Furthermore, a fluorescent layer is installed between the braided layer and the wear-resistant layer, and the fluorescent layer, the braided layer and the wear-resistant layer are fixed to each other.

[0016] By adopting the above technical solution, when the wear-resistant layer is damaged, the staff needs to repair the cable. The fluorescent layer can emit light in a darker environment, thereby reducing the difficulty for the staff to find the damaged part, thereby reducing the difficulty of the staff's work.

[0017] Furthermore, the high temperature resistant layer is a high temperature resistant layer made of mica tape.

[0018] By adopting the above technical solution, the mica tape has high temperature resistance and flame retardancy. The high temperature resistant layer made of mica tape reduces the probability of damage to the insulating sleeve when the temperature of the cable is too high, thereby reducing the probability of short circuit and extending the service life of the cable.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the present application, during the use of the cable, power and information are transmitted through the cable line. In this process, the cable core is strengthened to support the cable, thereby reducing the probability of deformation caused by mutual squeezing between cables. The insulating sleeve isolates each cable line so that each cable line can operate separately. The high temperature resistant layer reduces the probability of spontaneous combustion caused by overheating of the cable line during operation, thereby extending the service life of the device. The wrapping layer fixes the shape of the cable and reduces the probability of the cables being too loose. The insulation layer improves the cold resistance of the cable, thereby reducing the probability of a decrease in the working efficiency of the cable in a low temperature environment. In addition, the wear-resistant layer reduces the probability of skin damage to the cable;

[0021] 2. In the present application, the second insulating layer isolates the signal outside the cable, thereby reducing the probability of the cable being interfered with during operation;

[0022] 3. In the present application, the braided layer made of nylon material has the advantages of high strength, self-lubrication, and wear resistance, which can effectively avoid the probability of the inside of the cable being damaged when the wear-resistant layer is damaged, thereby extending the service life of the cable.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] like Figure 1-3As shown, the embodiment of the present application discloses a cold-proof and wear-resistant cable structure, including a reinforced cable core 1, a cable line 11, an insulating sleeve 12, a high temperature resistant layer 13, a sheath 2, a thermal insulation layer 3, a wear-resistant layer 4, a protective layer 5, a second insulating layer 51, a braided layer 7 and a fluorescent layer 6. The reinforced cable core 1 is a cylindrical structure with a horizontal axis. There are multiple cables 11 with horizontal axes, and multiple cable lines 11 are distributed on the outer wall of the reinforced cable core 1. There are multiple insulating sleeves 12 and they are sleeved on the outer walls of multiple cable lines 11, and their axes coincide with the axes of the cable lines 11. The high temperature resistant layer 13 is installed on the outer walls of multiple insulating sleeves 12, and its axis coincides with the axis of the reinforced cable core 1. The sheath 2 is installed on the outer wall of the high temperature resistant layer 13, and its axis coincides with the axis of the reinforced cable core 1. The thermal insulation layer 3 is fixed on the outer wall of the sheath 2, and its axis coincides with the axis of the reinforced cable core 1. The wear-resistant layer 4 is installed on the outer wall of the thermal insulation layer 3 , and its axis coincides with the axis of the reinforced cable core 1 .

[0029] During the use of the cable, power and information are transmitted through the cable line 11. In this process, the cable core 1 is strengthened to support the cable, thereby reducing the probability of deformation caused by mutual compression between cables. The insulating sleeve 12 isolates each cable line 11 so that each cable line 11 can operate independently. The high temperature resistant layer 13 reduces the probability of spontaneous combustion caused by overheating of the cable line 11 during operation, thereby extending the service life of the device. The sheath 2 fixes the shape of the cable and reduces the probability of the cables 11 being too loose. The insulation layer 3 improves the cold resistance of the cable, thereby reducing the probability of the cable's working efficiency decreasing in a low temperature environment. In addition, the wear-resistant layer 4 reduces the probability of skin damage to the cable.

[0030] The protective layer 5 is fixedly arranged on the outer wall of the thermal insulation layer 3, and its axis coincides with the axis of the reinforced cable core 1. The second insulating layer 51 is sleeved on the outer wall of the protective layer 5, and its axis coincides with the axis of the reinforced cable core 1.

[0031] The second insulating layer 51 isolates the signal outside the cable, thereby reducing the probability that the cable 11 is disturbed during operation.

[0032] The braided layer 7 is installed between the wear-resistant layer 4 and the second insulating layer 51 . The braided layer 7 and the second insulating layer 51 are fixed to each other, and the braided layer 7 is a braided layer made of nylon material.

[0033] The braided layer 7 made of nylon material has the advantages of high strength, self-lubrication, and wear resistance, and can effectively avoid the probability of the inside of the cable being damaged when the wear-resistant layer 4 is damaged, thereby extending the service life of the cable.

[0034] In order to reduce the probability of the cable 11 being affected, the protective layer 5 is a protective layer woven from copper wires 5. The protective layer 5 woven from copper wires has an anti-interference function, which reduces the probability of the electromagnetic field affecting the cable 11, thereby reducing the probability of the cable 11 being affected.

[0035] In order to reduce the probability of short circuit of the cable 11 during use, the insulating sleeve 12 is made of PVC material, and the second insulating layer 51 is made of PVC material. The PVC material has the advantages of light weight, strong corrosion resistance and good insulation performance, thereby reducing the probability of short circuit of the cable 11 during use.

[0036] The fluorescent layer 6 is installed between the braided layer 7 and the wear-resistant layer 4 , and the fluorescent layer 6 , the braided layer 7 and the wear-resistant layer 4 are fixed to each other.

[0037] When the wear-resistant layer 4 is damaged, the staff needs to repair the cable. The fluorescent layer 6 can emit light in a dark environment, thereby reducing the difficulty for the staff to find the damaged part, thereby reducing the difficulty of the staff's work.

[0038] In order to extend the service life of the cable, the high temperature resistant layer 13 is a high temperature resistant layer 13 made of mica tape. The mica tape has high temperature resistance and combustion resistance. The high temperature resistant layer 13 made of mica tape reduces the probability of damage to the insulating sleeve 12 when the temperature of the cable 11 is too high, thereby reducing the probability of short circuit, thereby extending the service life of the cable.

[0039] The use principle of a cold-proof and wear-resistant cable structure in this embodiment is as follows: during the use of the cable, power and information are transmitted through the cable line 11. During this process, the cable core 1 is strengthened to support the cable, thereby reducing the probability of deformation caused by mutual squeezing between cables. The insulating sleeve 12 isolates each cable line 11 so that each cable line 11 can operate separately. The high-temperature resistant layer 13 reduces the probability of spontaneous combustion caused by overheating of the cable line 11 during operation, thereby extending the service life of the device. The wrapping layer 2 fixes the shape of the cable and reduces the probability of the cables 11 being too loose. The insulation layer 3 improves the cold resistance of the cable, thereby reducing the probability of the cable's working efficiency decreasing in a low-temperature environment. In addition, the wear-resistant layer 4 reduces the probability of skin damage to the cable.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
