Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a high-temperature cable tensile-strength reinforced core structure. Background Technology

[0002] High-temperature cables are widely used in many industrial sectors, such as aerospace, metallurgical manufacturing, and energy extraction.

[0003] However, traditional high-temperature cables have obvious drawbacks, such as low tensile strength. In practical applications, cables often need to cope with complex installation environments and operating conditions, and inevitably will be subjected to a certain degree of tension. Once the cable is subjected to tension, this tension will directly act on the conductive core. If the conductive core is subjected to tension for a long time, it is easy for the internal metal wires to deform or even break. Once the conductive core breaks, it will not only cause a short circuit and affect the normal operation of the equipment, but may also cause serious safety accidents in some special environments. Therefore, there is an urgent need for a high-temperature cable tensile-strength reinforced core structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a tensile-strength reinforced core structure for high-temperature cables, in order to solve the problem mentioned in the background art that traditional high-temperature cables have low tensile strength and that when the cable is subjected to tensile force, the tensile force acts directly on the conductive core.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature cable tensile-strengthened core structure, comprising a main tube, wherein the inner wall of the main tube is provided with tensile-strength components;

[0006] The tensile component includes a tensile core, the surface of which is provided with a fixing groove, and the inner wall of the fixing groove is fixedly connected to a plurality of conductive cores. The surface of the main tube is provided with two clearance grooves, and the inner walls of the two clearance grooves are fixedly connected to the inner wall of the fixing groove.

[0007] Preferably, the diameter of the stretching core matches the diameter of the main tube, and the stretching core is made of alloy steel.

[0008] Preferably, the surface of the main tube is provided with a plurality of heat dissipation holes, and the plurality of heat dissipation holes are arranged in an arc shape.

[0009] Preferably, the thickness of the main tube is 0.5 cm, and the main tube is made of tungsten metal.

[0010] Preferably, the surface of the stretching core has two fixing holes, and the two fixing holes are of the same size.

[0011] Preferably, the multiple conductive cores are of the same size, and the multiple conductive cores are made of copper alloy.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up anti-tensile components, the tensile force is concentrated inside the tensile core. When the tensile core deforms, the multiple conductive cores inside the fixing groove will only unwind from the wrapped state, avoiding rapid tightening of multiple conductive cores that could damage the internal structure. This improves the tensile strength of multiple conductive cores. At the same time, the alloy steel tensile core has high strength and large tensile load, which facilitates the improvement of the overall tensile performance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a high-temperature cable tensile-strengthened core structure, including a main tube 1. The inner wall of the main tube 1 is provided with a tensile-strength component 2. The tensile-strength component 2 includes a tensile core 201. A fixing groove 202 is formed on the surface of the tensile core 201. Multiple conductive cores 203 are fixedly connected to the inner wall of the fixing groove 202. Two clearance grooves 204 are formed on the surface of the main tube 1. The inner walls of the two clearance grooves 204 are fixedly connected to the inner wall of the fixing groove 202. Through the tensile-strength component 2, the multiple conductive cores 203 are coiled in the inner wall of the fixing groove 202. When the tensile core 201 is fixed through the two fixing holes 206 and stretched, the tension is concentrated inside the tensile core 201. When the tensile core 201 deforms, the multiple conductive cores 203 inside the fixing groove 202 will only unwind from the coiled state, thereby avoiding the multiple conductive cores 203 from quickly tightening and damaging the internal structure, thus improving the tensile strength of the conductive core 203.

[0021] Furthermore, the diameter of the stretching core 201 matches the diameter of the main tube 1. The stretching core 201 is made of alloy steel. By using the alloy steel stretching core 201, the stretching core 201 has high strength and large tensile load, which facilitates the improvement of the overall tensile performance.

[0022] Furthermore, the surface of the main tube 1 is provided with multiple heat dissipation holes 205. The multiple heat dissipation holes 205 are arc-shaped. The multiple heat dissipation holes 205 facilitate the flow of heat from the surface of the multiple conductive cores 203 through the multiple heat dissipation holes 205, thereby reducing the internal temperature of the conductive cores 203 and improving the tensile strength.

[0023] Furthermore, the thickness of the main tube 1 is 0.5 cm, and the main tube 1 is made of tungsten metal. By using the tungsten metal main tube 1, it is easier to improve the high temperature resistance of the main tube 1, thereby making it easier to adapt to more high temperature environments.

[0024] Furthermore, two fixing holes 206 are provided on the surface of the stretching core 201. The two fixing holes 206 are of matching size, and the two fixing holes 206 make it easy to connect the stretching core 201 through the two fixing holes 206.

[0025] Furthermore, the multiple conductive cores 203 are matched in size and are made of copper alloy. By using copper alloy conductive cores 203, good conductivity is maintained even at high temperatures, thus making it easier to meet more high-temperature application scenarios.

[0026] Working principle: Through the set tensile component 2, multiple conductive cores 203 are coiled on the inner wall of the fixing groove 202. When the tension core 201 is fixed through the two fixing holes 206 and stretched, the tension is concentrated inside the tension core 201. When the tension core 201 deforms, the multiple conductive cores 203 inside the fixing groove 202 will only unwind from the coiled state, thereby avoiding the multiple conductive cores 203 from quickly tightening and damaging the internal structure, thus improving the tensile strength of the multiple conductive cores 203. At the same time, the alloy steel tension core 201 has high strength and large tensile load, which facilitates the improvement of the overall tensile performance.
