Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a cable with high tensile strength. Background Technology

[0002] A cable is a conductor assembly used to transmit electrical energy or signals. It typically consists of one or more insulated conductors and an outer protective sheath, playing a vital role in numerous fields such as power, communications, construction, and industrial control. The structure of a cable includes a conductor, insulation layer, shielding layer, filler layer, and sheath layer.

[0003] The conductor is the part of the cable that carries current. It is usually made of multiple strands of copper or aluminum wire twisted together to improve the conductor's flexibility and bending performance. The cross-sectional area of ​​the conductor directly affects the current carrying capacity of the cable; the larger the cross-sectional area, the greater the current that can be passed through.

[0004] The insulation layer wraps around the conductor, and its main function is to prevent current leakage and ensure the electrical performance and safe operation of the cable. Different insulation materials have different performance characteristics, such as withstand voltage rating, insulation resistance, and heat resistance, and must be selected according to the cable's operating environment and requirements.

[0005] In some cables, a shielding layer is placed outside the insulation layer to reduce interference from external electromagnetic fields on signals within the cable, or to prevent electromagnetic signals within the cable from interfering with external signals. Shielding layers are generally made of materials such as metal foil (e.g., aluminum foil) or metal braided mesh (e.g., copper wire braided mesh). For example, in communication cables, the shielding layer can effectively improve the quality and stability of signal transmission; in high-voltage power cables, the shielding layer can also uniformly distribute the electric field and prevent partial discharge.

[0006] For multi-core cables, in order to make the cable structure compact and round, soft materials such as hemp rope, polypropylene rope, and fiberglass rope are filled between the cores. These filler materials can also play a certain role in cushioning and protection.

[0007] The sheath layer is the outermost protective structure of a cable, and its main function is to protect the internal structure of the cable from external mechanical damage, chemical corrosion, humid environments, and other factors. Sheath materials typically have good abrasion resistance, corrosion resistance, weather resistance, and flame retardancy. Common sheath materials include polyvinyl chloride (PVC), polyethylene (PE), neoprene rubber, and polyurethane.

[0008] During the installation of high-voltage cables, when the construction area involves complex terrain such as mountains and ravines, it is often necessary to cross natural obstacles hundreds or even thousands of meters long, resulting in a significant increase in the spacing (span) between cable support points. Under these circumstances, the cable continuously bears the axial tension generated by its own weight, and stress will accumulate in its internal composite structure consisting of conductors, insulation layers, shielding layers, and sheaths. Long-term tension will cause irreversible damage such as micro-cracks in the insulation layer and loosening of the conductor strands. When the stress exceeds the fatigue limit of the material, the local strength of the cable will drop sharply, significantly increasing the risk of fracture failure during operation.

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.

[0026] Please see Figures 1-4 The present invention provides the following technical solution: a cable with high tensile strength, comprising a cable body 1, a connecting component 2 installed on the surface of the cable body 1, and a steel wire 3 passing through the interior of the connecting component 2;

[0027] The connecting assembly 2 includes a connecting frame 201, a fixed clamp 202, a movable clamp 203, a first internal threaded tube 206, a first screw 207, a knob 208, and a bearing 209. The connecting frame 201 is sleeved on the surface of the cable body 1. The fixed clamp 202 is connected to the side surface of the connecting frame 201. The movable clamp 203 is provided on the side surface of the connecting frame 201. The first internal threaded tube 206 is connected through the side surface of the connecting frame 201. The first screw 207 is passed through the inside of the first internal threaded tube 206. The knob 208 is connected to the end of the first screw 207. The bearing 209, which is fitted and installed on the side surface of the movable clamp 203, is sleeved on the end of the first screw 207.

[0028] Preferably, the first internally threaded tube 206 is adapted to the first screw 207, and the first internally threaded tube 206 and the first screw 207 are threadedly connected.

[0029] In practical use, when the first screw 207 rotates inside the first internal threaded tube 206, it can move laterally through the threaded connection. The lateral movement of the first screw 207 can drive the movable clamping block 203 to move laterally through the bearing 209.

[0030] Preferably, an arc groove is provided on the side surface of the fixed clamp 202 that is close to the movable clamp 203.

[0031] In practical use, the steel wire 3 can be clamped and fixed by the movable clamp 203 and the fixed clamp 202.

[0032] Preferably, the connecting component 2 further includes a slider 204 and a groove 205. The slider 204 is connected to the side surface of the movable clamp 203, and the side surface of the connecting frame 201 is provided with a groove 205 that is adapted to the size of the slider 204.

[0033] In practical use, when the movable clamping block 203 is subjected to a force, it can drive the slider 204 to slide inside the slide groove 205, which can restrict the movement direction of the movable clamping block 203.

[0034] Preferably, the inner wall of the connecting frame 201 is connected to a rubber pad 210, the side surface of the connecting frame 201 is provided with a round hole 211, the inside of the round hole 211 is through a second screw 212, and the side surface of the connecting frame 201 is through connected to a second internal threaded tube 213.

[0035] In practical use, the rubber pad 210 is designed to prevent damage to the sheath of the cable body 1 when the connecting bracket 201 is fixed to the surface of the cable body 1.

[0036] Preferably, the second screw 212 is adapted to the second internal threaded tube 213, and the second screw 212 and the second internal threaded tube 213 are threadedly connected.

[0037] In practical use, when the second screw 212 rotates inside the second internal threaded tube 213, it can move laterally through the threaded connection. When the second screw 212 moves, it can tighten the opening of the connecting frame 201, thereby fixing the connecting frame 201 to the surface of the cable body 1.

[0038] Working principle: First, the connecting bracket 201 is placed on the surface of the cable body 1. Then, the second screw 212 passes through the round hole 211 and moves to the end of the second internal thread tube 213. Then, the second screw 212 can be rotated. When the second screw 212 rotates at the end of the second internal thread tube 213, it can move into the inside of the second internal thread tube 213. This can tighten the opening of the connecting bracket 201. When the connecting bracket 201 drives the rubber pad 210 to press against the surface of the cable body 1, the connecting bracket 201 can be fixedly connected to the surface of the cable body 1.

[0039] Next, place the steel wire 3 between the fixed clamp 202 and the movable clamp 203, and then turn the knob 208. When the knob 208 turns, it can drive the first screw 207 to rotate. When the first screw 207 rotates inside the first internal thread tube 206, it can move laterally. When the first screw 207 moves laterally, it can drive the movable clamp 203 to move closer to the fixed clamp 202 through the bearing 209. In this way, the steel wire 3 can be clamped by the movable clamp 203 and the fixed clamp 202, thereby improving the tensile strength of the cable body 1 through the steel wire 3.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
