Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a coaxial cable with a built-in reinforcement layer. Background Art

[0002] Coaxial cable is a commonly used transmission medium with a structure of inner conductor, insulation layer, outer conductor and sheath. However, when multiple groups of different signals need to be transmitted, the wiring using multiple coaxial cables becomes complicated and may cause signal interference, transmission attenuation and loss. In addition, the distance between the inner conductor and the shielding layer of a single core cable is large, resulting in a large inductance and low tensile strength. Coaxial cables are usually used for aerial installation, underground laying or underwater applications for telecommunications or power transmission. In order to ensure the normal and stable operation of the cable, the cable needs to have basic safety performance, such as waterproofness and flame retardancy. However, heat is generated when the cable passes through. Since the wires inside the cable are located in a closed space, the heat dissipation relies on the insulation layer to transfer heat, and this heat dissipation efficiency is low. At the same time, the existing coaxial cables have poor bending and compression resistance, and when subjected to external forces, signal loss or damage will occur. Utility Model Content

[0003] The utility model aims to solve the shortcomings existing in the background technology and provide a coaxial cable with a built-in reinforcement layer. The heat dissipation performance of the cable can be improved through the heat dissipation component. The good heat dissipation capacity can effectively reduce the temperature of the cable during operation and reduce the aging of the insulating material caused by high temperature, thereby extending the overall service life of the cable and reducing the replacement and maintenance costs. Secondly, the bending and compression resistance of the cable can be improved through the pressure-resistant component. When subjected to external extrusion, the cable can be evenly distributed with force to resist pressure from different directions, provide excellent structural strength, avoid damage to the insulation layer and exposure of the conductor, and then cause safety hazards such as short circuit, leakage and even fire.

[0007] A pressure-resistant component is arranged between the protective sleeve and the three sub-wires to improve the pressure resistance of the cable. The pressure-resistant component includes: a support tube, a honeycomb layer and a buffer layer.

[0008] Furthermore, a heat-conducting sleeve is provided outside the three sub-wires, and a plurality of equidistantly distributed heat sinks are fixedly connected to the outside of the heat-conducting sleeve. The plurality of heat sinks respectively penetrate the protective sleeve and extend to the outside, and a plurality of equidistantly distributed grooves are respectively provided on opposite sides of the plurality of heat sinks.

[0009] Furthermore, two support tubes are provided between the protective sleeve and the three sub-wires, a honeycomb layer is fixedly connected between the two support tubes, and a buffer layer is provided outside the support tubes.

[0010] Furthermore, the heat-conducting sleeve and the heat sink are made of heat-conducting silicone material as a whole, and the connection between the heat sink and the protective sleeve is sealed.

[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Example 1

[0028] See also Figure 1-5 In the embodiment, a coaxial cable with a built-in reinforcement layer is provided, comprising: a reinforcing core 1, three sub-wires 11 distributed in a ring array are arranged on the outside of the reinforcing core 1, an anti-interference layer 12 is arranged on the outside of the sub-wire 11, and protective sleeves 13 are respectively arranged on the outside of the three sub-wires 11, a heat dissipation component, the heat dissipation component is arranged on the outside of the three sub-wires 11, and is used to improve the heat dissipation efficiency of the cable, the heat dissipation component comprises: a thermal conductive sleeve 2, a heat dissipation plate 21 and a groove 22, a pressure-resistant component, the pressure-resistant component is arranged between the protective sleeve 13 and the three sub-wires 11, and is used to improve the pressure resistance of the cable, and the pressure-resistant component comprises: a support tube 3, a honeycomb layer 31 and a buffer layer 32.

[0029] The reinforcing core 1 can improve the tensile strength of the cable, the protective cover 13 outside the sub-line 11 can insulate and improve the bending resistance of the cable, reduce signal loss or damage caused by external force, and the anti-interference layer 12 can reduce external interference. The heat dissipation performance of the cable can be improved through the heat dissipation component. Secondly, the bending resistance and compression resistance of the cable can be improved through the pressure-resistant component.

[0030] Example 2

[0031] On the basis of Example 1, a thermally conductive sleeve 2 is provided outside the three sub-wires 11, and a plurality of equidistantly distributed heat sinks 21 are fixedly connected to the outside of the thermally conductive sleeve 2. The plurality of heat sinks 21 respectively penetrate the protective sleeve 13 and extend to the outside, and a plurality of equidistantly distributed grooves 22 are respectively provided on opposite sides of the plurality of heat sinks 21. The thermally conductive sleeve 2 and the heat sinks 21 are made of thermally conductive silicone material as a whole, and the connection between the heat sink 21 and the protective sleeve 13 is sealed.

[0032] When in use, excessive heat will be generated when current passes through. The heat is transferred to the thermal sleeve 2 through the protective sleeve 13 and the anti-interference layer 12. The thermal sleeve 2 absorbs the heat and then transfers it to a number of heat sinks 21. The heat is dissipated into the air through the heat sinks 21. The grooves 22 on the heat sinks 21 can increase the heat dissipation area. The thermally conductive silicone material has strong thermal conductivity, electrical insulation, wear resistance, flexibility and elasticity, thereby improving the heat dissipation performance of the cable.

[0035] When the cable is in use, the support tube 3 can provide support to resist external pressure, and the honeycomb layer 31 can increase the compression and bending resistance. The honeycomb structure has several hexagonal structures arranged, and the hexagonal structure is one of the most stable geometric shapes in nature. It can evenly distribute the force, effectively resist pressure from different directions, and provide excellent structural strength. The buffer layer 32 can absorb the impact force, thereby improving the cable's bending and compression resistance.

[0036] Among them, the protective sleeve 13 is made of polytetrafluoroethylene material as a whole, and multiple anti-slip grooves 4 are opened on the outside of the protective sleeve 13. The polytetrafluoroethylene material has extremely strong chemical stability and is not corroded by strong acids, strong alkalis, strong oxidants, etc. It is an excellent electrical insulating material that can maintain good dielectric properties even at high frequencies and is not affected by humidity, thereby improving strength.

When the two sections of the line are connected, the two reinforcing cores 1 are welded together, which can improve the stability of the connection and avoid disconnection due to excessive tension.
