Description

Technical Field

[0001] The utility model belongs to the technical field of insulating cables, and in particular relates to an ultra-thin-wall insulating cable for vehicles. Background Art

[0002] Insulated cables are usually rope-like cables made of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation.

[0003] In the prior art, insulated cables are required during the manufacturing process of vehicles to lay circuits in the vehicle so that the electrical components in the vehicle can operate. However, the internal space of the vehicle is limited, and the diameter of the existing insulated cables is relatively long. Therefore, laying them in the vehicle will not only cause inconvenience in installation, but also take up more space. By reducing the diameter width of the existing insulated cables, the quality of the insulated cables will deteriorate. As a result, the components and circuits in the vehicle are very easy to be damaged, resulting in maintenance troubles. Therefore, we propose an ultra-thin wall insulated cable for vehicles. Utility Model Content

[0004] The utility model aims to provide an ultra-thin-wall insulated cable for vehicles, so as to solve the technical problems that the insulated cable is inconvenient to install, occupies space, and reducing the diameter width of the insulated cable will cause quality deterioration, so as to achieve the purpose of convenient installation, reducing the occupied space, and avoiding the deterioration of the quality of the insulated cable.

[0005] In order to solve the above technical problems, the utility model provides an ultra-thin-wall insulated cable for vehicles, comprising five wire cores for conducting electricity, and a fire-resistant layer that is fire-resistant is arranged on the periphery of the wire core, an insulating layer that can insulate current is sleeved on the periphery of the fire-resistant layer, a filling layer that can fill the gaps between the insulating layers is filled on the periphery of the insulating layer, and an inner lining layer that enables the filling layer to tightly fill the insulating layer is sleeved on the periphery of the filling layer, and a supporting layer that ensures the hardness of the inner lining layer is sleeved on the periphery of the inner lining layer, and a sheath that protects the supporting layer is sleeved on the periphery of the supporting layer, and lugs are symmetrically arranged on both sides of the periphery of the sheath, and connection holes for fixing the sheath are penetrated through the tops of the lugs.

[0006] Furthermore, the fire-resistant layer is painted on the surface of the wire core with fire-resistant paint, the thickness of the fire-resistant layer is 0.3 mm, and the painting error of the fire-resistant layer is ±0.02.

[0007] Through the above scheme, the fire-resistant layer can effectively resist fire, thereby protecting the wire core.

[0008] Furthermore, the insulating layer is made of EPDM rubber, and the thickness of the insulating layer is 0.5 mm.

[0009] Furthermore, the filling layer is made of glass fiber rope, and the glass fiber rope is used to limit the insulating layer by clamping, so as to ensure the stability of the wire core.

[0010] Furthermore, the inner lining layer is made of cable paper material, and the cable paper needs to be pre-impregnated before being sheathed outside the filling layer, and the thickness of the inner lining layer is 0.5 mm.

[0011] Furthermore, the support layer is made of steel strip material, and the thickness of the support layer is 0.8 mm.

[0012] Furthermore, the sheath is made of polytetrafluoroethylene propylene material, and the thickness of the sheath is 0.8 mm.

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

[0014] 1. The fire resistance can be effectively improved by setting the fire-resistant layer. The diameter of the cross section is not long through the fire-resistant layer, the insulating layer, the filling layer, the lining layer, the supporting layer and the sheath. The material is solid, which can play a good insulation effect. The ultra-thin wall ensures the quality while being easy to install. It also takes up very little space, which increases the installation space of other components in the car.

[0015] 2. The setting of lugs and connecting holes makes it easy to install the cable, and the sheath can be effectively fixed on the inner wall of the vehicle, making the installation more convenient and having a good fixing effect. During the use of the vehicle, it will not shake due to bumps, making the cable more stable.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0032] Example:

[0033] like Figures 1 to 3 As shown, an ultra-thin-wall insulated cable for vehicles comprises five wire cores 1 for conducting electricity, and a fire-resistant refractory layer 2 is arranged on the periphery of the wire core 1, an insulating layer 3 capable of insulating current is sleeved on the periphery of the fire-resistant layer 2, a filling layer 4 capable of filling the gaps between the insulating layers 3 is filled on the periphery of the insulating layer 3, and an inner lining layer 5 is sleeved on the periphery of the filling layer 4 so that the filling layer 4 can tightly fill the insulating layer 3, and a supporting layer 6 for ensuring the hardness of the inner lining layer 5 is sleeved on the periphery of the inner lining layer 5, and a sheath 7 for protecting the supporting layer 6 is sleeved on the periphery of the supporting layer 6, and lugs 8 are symmetrically arranged on both sides of the periphery of the sheath 7, and the distribution distance between the lugs 8 is 30 cm, and connection holes 9 for fixing the sheath 7 are penetrated through the tops of the lugs 8.

[0034] Example 2

[0035] This embodiment includes: the fire-resistant layer 2 is painted on the surface of the wire core 1 with fire-resistant paint, and the thickness of the fire-resistant layer 2 is 0.3mm, and the painting error of the fire-resistant layer 2 is ±0.02. The fire-resistant layer 2 can effectively protect the wire core 1, and the thickness of the fire-resistant layer 2 is very thin, and the good fire-resistant performance facilitates reducing the thickness of the cable.

[0036] The insulating layer 3 is made of EPDM rubber, and the thickness of the insulating layer 3 is 0.5 mm. The EPDM rubber material has a large current carrying capacity, does not contain halogen, does not emit a large amount of smoke when burned, and also has flame retardant properties and ozone resistance stability. It can be used in a low temperature environment of -50°C, so the insulation performance is very good.

[0037] The filling layer 4 is made of glass fiber rope, and the glass fiber rope limits the insulating layer 3 by clamping, so as to ensure the stability of the core 1. The filling layer 4 can effectively fill the gaps between the cores 1, thereby preventing the core 1 from being unstable and reducing the service life of the cable.

[0038] The inner lining layer 5 is made of cable paper material, and the cable paper needs to be pre-impregnated before being sheathed outside the filling layer 4. The thickness of the inner lining layer 5 is 0.5 mm, which can effectively prevent corrosion and make the filling layer 4 more stable.

[0039] The support layer 6 is made of steel strip material, and the thickness of the support layer 6 is 0.8 mm, which can effectively resist pressure and ensure the hardness of the cable.

[0040] The sheath 7 is made of fluoroethylene propylene material, and the thickness of the sheath 7 is 0.8 mm, which can effectively withstand high temperatures and prevent the inner layer from being mechanically damaged.

[0041] In summary, the utility model can effectively and conveniently lay the insulated cable in the vehicle through the design, reduce the occupied space, and the quality of the insulated cable is also guaranteed.
