Description

Technical Field

[0001] This utility model mainly relates to the field of signal transmission connection line technology, specifically a signal transmission connection line with a power connection line. Background Technology

[0002] With the continuous development of modern science and technology, the pace of upgrades and iterations of signal cables is accelerating. Simultaneously, information networks are expanding rapidly alongside the continuous advancement of network technology. In traditional cabling projects, power cables and signal lines are typically laid separately. However, this method increases the workload of cable laying, is time-consuming and labor-intensive, and wastes human resources. These problems, in turn, negatively impact the project's progress and reduce overall efficiency.

[0003] For example, an existing patent application (application number CN202222835382.2) proposes a signal transmission connection cable comprising a main body and connectors. The connectors are fixed to both ends of the main body, which includes a first hollow tube, a second hollow tube, a power connection cable, and multiple signal transmission cables. Specifically, a connecting strip is arranged around the outer side of the second hollow tube, allowing it to be stably installed inside the first hollow tube. Through the combined action of the first and second hollow tubes and the connecting strip, the gap between the first and second hollow tubes is divided into multiple signal transmission cable mounting cavities, while the hollow portion of the second hollow tube forms the power cable mounting cavity. This device incorporates anti-interference layers on both the power connection cable and the signal transmission cables, thus providing a degree of electromagnetic interference resistance and making signal transmission more stable. However, existing signal transmission connection cables are prone to breakage or damage when subjected to external forces such as tension, affecting the stability and security of information transmission. Therefore, a signal transmission connection cable with a power connection cable is proposed. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing signal transmission cables are too simplistic. It mainly provides a signal transmission cable with a power connection line to solve the technical problem mentioned in the background that existing signal transmission cables are prone to breakage or damage when subjected to external forces such as tension.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A signal transmission cable with a power connection line includes a cable body with connectors for connecting to the outside world at both ends. The cable body includes a power connection line, a signal transmission line, and a filling layer. The power connection line, signal transmission line, and filling layer are wrapped with a wrapping tape to form a circular cross-section. The filling layer includes a filling rope, and a central cable is provided at the center of the filling layer. The filling layer is filled with aramid fibers. A hollow pressure-reducing layer is provided on the outside of the wrapping tape. The hollow pressure-reducing layer has several axial pressure-reducing holes and several tensile reinforcing ropes are axially embedded in the hollow pressure-reducing layer.

[0007] Preferably, the power connection cable includes a power connection cable body, and a first anti-interference layer and a protective sleeve are sequentially disposed on the outer side of the power connection cable body.

[0008] Preferably, the signal transmission line includes an elastic body, and the elastic body has three sets of cable holes for installing the signal transmission line body. A second anti-interference layer is provided on the outside of the signal transmission line body. A tension hole is provided at the center of the elastic body, and a tension rope is installed in the tension hole.

[0009] Preferably, the signal transmission lines are provided in two sets, and the signal transmission lines and the power connection lines are arranged in a triangular pattern.

[0010] Preferably, a protective sleeve is provided on the outside of the hollow pressure-reducing layer, and the protective sleeve is covered with hemp rope fiber mesh.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By axially embedding several tensile reinforcing ropes in the hollow pressure-reducing layer, and combining the aramid fibers, filling ropes, central cable, and the elastic body and tension ropes in the signal transmission line, the overall tensile strength of the connecting line is improved. This design enables the connecting line to better resist deformation when subjected to external forces such as tension, reducing the possibility of breakage or damage caused by external forces, thereby enhancing the reliability and service life of the connecting line.

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please refer to the appendix carefully. Figure 1-3 A signal transmission cable with a power connection cable, wherein the cable body 1 has connectors 2 at both ends for connecting to the outside world, and the cable body 1 includes a power connection cable 3, a signal transmission cable 4, and a filling layer 5.

[0023] Specifically, the power connection line 3, the signal transmission line 4, and the filling layer 5 are wrapped by the wrapping tape 6 into a circular cross-section. The filling layer 5 includes a filling rope 501, and a central cable 502 is provided at the center of the filling layer 5. The filling layer 5 is filled with aramid fibers. A hollow pressure-reducing layer 7 is provided on the outside of the wrapping tape 6. Several axial pressure-reducing holes are provided in the hollow pressure-reducing layer 7, and several tensile reinforcing ropes 701 are also axially embedded in the hollow pressure-reducing layer 7.

[0024] To further explain, the wrapping tape 6 is a polyester wrapping tape with two layers. In order to prevent the electromagnetic field generated by itself from interfering with the surrounding environment and the effect of fault current during use, a copper foil wire shielding layer is set on the outer wall of the wrapping tape 6. The copper foil wire shielding layer is formed by weaving tin-plated copper foil wire.

[0025] To further explain, the filler rope 501 is usually made of a material with a certain degree of elasticity and strength, such as high-strength fiber or synthetic material, to ensure that while providing support, it can also adapt to the deformation requirements of the wire body 1 in different environments; the central cable 502 plays a key role in bearing external tension and maintaining the overall shape and stability of the wire. By setting the central cable 502, the tensile strength and durability of the wire body 1 can be improved. The central cable 502 can be made of aramid fiber or synthetic fiber composite material. These materials have excellent tensile strength and toughness and can effectively resist the influence of external tension on the wire.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, the power connection cable 3 includes a power connection cable body, and a first anti-interference layer and a protective sleeve 8 are sequentially arranged on the outside of the power connection cable body.

[0027] Through the above structure, the first anti-interference layer can shield external electromagnetic interference. It is usually made of highly conductive materials such as aluminum foil or metal braided mesh, which can prevent electromagnetic waves from entering or leaving the power connection line 3, thereby ensuring the pure and stable transmission of power signals. The protective sleeve 8, as the outer protective layer, provides comprehensive physical protection for the power connection line 3. The protective sleeve 8 can be made of elastic material.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the signal transmission line 4 includes an elastic body 401, and the elastic body 401 has three sets of cable holes for installing the signal transmission line body. A second anti-interference layer is provided on the outside of the signal transmission line body. A tension hole is provided at the center of the elastic body 401, and a tension rope 402 is installed in the tension hole. The tension rope 402 can be made of high-strength fibers such as nylon, polyester or aramid. There are two sets of signal transmission lines 4, and the signal transmission lines 4 and the power connection line 3 are triangularly distributed.

[0029] Through the above structure, the introduction of the elastomer 401 enables the signal transmission line 4 to possess a certain degree of flexibility and elasticity. This characteristic helps the signal transmission line 4 to better adapt to various complex wiring environments during installation and use, such as bending and twisting. At the same time, the elastomer 401 can also absorb some external forces, protecting the internal signal transmission line body from damage, thereby improving the overall structural durability. The second anti-interference layer set on the outside of the signal transmission line body effectively shields external electromagnetic interference, ensuring the stability and accuracy of signal transmission. This layer is made of highly conductive material and can prevent electromagnetic waves from interfering with the signal transmission line 4. The tension rope 402 installed in the tension hole at the center of the elastomer 401 provides additional tensile strength for the signal transmission line 4. When the signal transmission line 4 is stretched by external force, the tension rope 402 can disperse and absorb the tension, preventing the signal transmission line 4 from breaking or being damaged due to excessive stretching. This design not only improves the tensile strength of the signal transmission line 4, but also increases its safety and reliability during use.

[0030] In this embodiment, as Figure 2 and Figure 3 As shown, a protective sleeve 8 is provided on the outside of the hollow pressure-reducing layer 7. The protective sleeve 8 can be made of rubber material, and the inside of the protective sleeve 8 is covered with hemp rope fiber mesh. A connecting layer is provided between the hollow pressure-reducing layer 7 and the wrapping tape 6 to improve the connection between the hollow pressure-reducing layer 7 and the wrapping tape 6. The hollow pressure-reducing layer 7 can be made of elastic material.

[0031] Through the above structure, the protective sleeve 8 provides an additional protective layer for the hollow pressure-reducing layer 7, which can effectively resist the erosion and mechanical damage of the external environment, such as wear and tear. The hemp fiber mesh covering further enhances the strength and toughness of the protective sleeve 8, making it more durable in the face of complex and ever-changing usage environments. The connection layer strengthens the bonding force between the hollow pressure-reducing layer 7 and the wrapping tape 6, ensuring a tight connection between the two. The axial pressure-reducing holes in the hollow pressure-reducing layer 7 can reduce the impact pressure by the deformation of the hole walls around the holes when the cable is subjected to radial impact or crushing.

[0032] The specific operating procedure of this utility model is as follows: The signal transmission connection cable mainly consists of a connector 2, a power connection cable 3, a signal transmission cable 4, a filling layer 5, a wrapping tape 6, a hollow pressure-reducing layer 7, and a protective sleeve 8. The signal transmission cable 4 is responsible for signal transmission, and the power connection cable 3 is responsible for power transmission. The filling layer 5 is located between the power connection cable 3 and the signal transmission cable 4, and is composed of a filling rope 501 and a central cable 502. It is also filled with aramid fibers to enhance the internal support of the cable body 1, improve the overall structural stability and tensile strength. The wrapping tape 6 further enhances the structural strength of the cable body 1. The hollow pressure-reducing layer 8... The inner layer 7 is equipped with axial pressure relief holes and tensile reinforcing ropes 701. The axial pressure relief holes help to reduce impact pressure, while the tensile reinforcing ropes 701 enhance the tensile strength of the wire body 1. The protective sleeve 8 not only provides additional protection for the wire body 1, but also facilitates operation during installation and maintenance. When the wire body 1 is subjected to tension or pressure, the tensile reinforcing ropes 701 and the wrapping tape 6 in the hollow pressure relief layer 7 jointly bear the external force, effectively preventing the wire body 1 from breaking or being damaged. At the same time, the filling ropes 501 and the central cable 502 in the filling layer 5 also provide additional support, further enhancing the tensile and compressive strength of the wire body 1.

[0033] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
