Description

Technical Field

[0001] This utility model relates to the field of communication cables, and in particular to a high-temperature resistant and high-strength spring-shielded communication cable. Background Technology

[0002] In industrial high-temperature equipment (such as kilns and heat treatment equipment), aerospace high-temperature areas, automotive engine compartments, as well as robotic arms, telescopic equipment, and industrial scenarios with frequent vibrations, there are extremely high requirements for the high-temperature resistance and flexibility of communication cables. However, existing communication cables have many shortcomings in these application scenarios: the outer sheath of existing cables is mostly of conventional shape and ordinary material, which cannot provide sufficient mechanical protection to resist external compression, impact, and abrasion, nor does it have excellent flexibility and fatigue resistance, making it difficult to adapt to scenarios with frequent movement and bending. Moreover, the protective performance is prone to failure in high-temperature environments, failing to meet the comprehensive performance requirements of communication cables.

[0003] To address the aforementioned problems, this invention proposes a high-temperature resistant, high-strength, and highly flexible spring-shielded communication cable with fatigue resistance. Utility Model Content

[0004] The main purpose of this invention is to propose a high-temperature resistant and high-strength spring-shielded communication cable, which aims to solve the problem that the existing communication cables have poor flexibility and fatigue resistance, making them difficult to adapt to scenarios involving frequent movement and bending.

[0005] To solve the above problems, this utility model proposes a high-temperature resistant and high-strength spring-shielded communication cable, comprising: multiple insulating sheaths, each of which has a twisted wire pair inside; a first high-temperature resistant PTFE tape wrapped around the outside of the multiple insulating sheaths; a braided layer wrapped around the outside of the first high-temperature resistant PTFE tape; a second high-temperature resistant PTFE tape wrapped around the outside of the braided layer; and a spring sheath wrapped around the outside of the second high-temperature resistant PTFE tape.

[0006] In one embodiment, the stranded pair includes a conductor, a bulletproof wire, and multiple insulating sheaths, each containing multiple conductors and a bulletproof wire.

[0007] In one embodiment, multiple conductors are twisted together with a ballistic wire to form a stranded pair.

[0008] In one embodiment, among a plurality of insulating sheaths, the gap between two adjacent insulating sheaths is filled with Kevlar filler.

[0009] In one embodiment, multiple insulating sheaths and spring sheaths are made of high-temperature resistant Teflon material.

[0010] In one embodiment, the communication cable is in the shape of a spiral spring when no external force is applied.

[0011] Beneficial effects: 1. The stranded wire pair adopts a stranded structure design with multiple conductors and a single elastic wire, which enables the conductors to stably transmit electrical signals. The elastic wire can serve as a reinforcing skeleton to improve the tensile and fracture resistance of the stranded wire pair itself, preventing the conductors from breaking when bent or under stress. At the same time, the stranding process can also reduce the influence of external electromagnetic interference on the signal by utilizing structural symmetry, and improve the flexibility of the stranded wire pair.

[0012] 2. Each stranded pair is independently wrapped with an insulating sheath made of high-temperature resistant Teflon material, which can achieve electrical isolation between adjacent stranded pairs, prevent crosstalk between signals of different stranded pairs, and ensure that the signals of each transmission channel are independent and stable. At the same time, Teflon material has excellent high temperature resistance, insulation and chemical stability, which can protect the internal stranded pairs from minor wear and chemical corrosion, and meet the core requirement of high temperature resistance of cables.

[0013] 3. Filling the gaps between multiple insulating sheaths with Kevlar material makes the internal structure of the cable more compact, preventing the insulating sheaths from shifting or colliding when bent or vibrating. At the same time, it significantly improves the overall tensile and impact resistance of the cable and extends its service life.

[0014] 4. The outermost layer is made of high-temperature resistant Teflon material with a spring sheath. The cable is in the shape of a spiral spring when there is no external force. Teflon material has excellent high-temperature resistance. The spring sheath can resist external compression and wear while protecting the internal structure to reduce physical damage. The spiral spring shape gives the cable excellent flexibility and fatigue resistance. It can be repeatedly stretched and bent without breaking. It can be adapted to frequent activities and bending scenarios. At the same time, the spring structure can disperse external force, reduce local stress concentration, and extend the service life of the cable. Attached Figure Description

[0018] 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.

[0019] To achieve the above-mentioned utility model objectives, such as Figure 1-2 As shown, this utility model provides a high-temperature resistant and high-strength spring-shielded communication cable, including: multiple insulating sheaths 1, each of the multiple insulating sheaths 1 having a twisted wire pair inside, the multiple insulating sheaths 1 being wrapped with a first high-temperature resistant PTFE tape 2, the first high-temperature resistant PTFE tape 2 being wrapped with a braided layer 3, the braided layer 3 being wrapped with a second high-temperature resistant PTFE tape 4, and the second high-temperature resistant PTFE tape 4 being wrapped with a spring sheath 5.

[0020] Preferred, such as Figure 2 As shown, the stranded pair includes a conductor 6 and a bulletproof wire 7. Multiple insulating sheaths 1 each contain multiple conductors 6 and a bulletproof wire 7. The multiple conductors 6 and the bulletproof wire 7 are twisted together to form a stranded pair.

[0021] Preferred, such as Figure 2 As shown, among the multiple insulating sleeves 1, the gap between two adjacent insulating sleeves 1 is filled with Kevlar filler 8.

[0022] Preferably, the multiple insulating sleeves 1 and spring sleeves 5 are all made of high-temperature resistant Teflon material.

[0023] Preferred, such as Figure 1 As shown, the communication cable takes on a spiral spring shape when no external force is applied.

[0024] When using, such as Figure 2As shown, the bulletproof wire 7 is evenly distributed between the conductors 6, providing reinforced support for the stranded pairs to resist tensile and fracture. The Teflon insulating sheath 1 enables reliable electrical isolation between adjacent stranded pairs, preventing signal crosstalk while ensuring excellent high-temperature resistance. The Kevlar material filling the gap between two adjacent insulating sheaths 1 makes the internal structure of the cable compact, preventing the insulating sheaths 1 from shifting or colliding during subsequent use, while also improving the overall tensile and impact resistance of the cable. The first high-temperature resistant PTFE tape 2 is tightly wrapped around the outside of the multiple sets of insulating sheaths 1 and Kevlar filler 8, making the multiple sets of insulating sheaths 1 and Kevlar filler 8 form a whole, ensuring high-temperature resistance. For continuity, the braided layer 3 outside the first high-temperature resistant PTFE tape 2 effectively blocks external electromagnetic radiation interference and prevents signal leakage from the cable itself, ensuring the integrity of communication signals. Then, the second high-temperature resistant PTFE tape 4 wrapped around the braided layer 3 further enhances the high-temperature resistance. Finally, the spring sheath 5 wrapped around the second high-temperature resistant PTFE tape 4 is made of high-temperature resistant Teflon material through extrusion molding combined with spring processing technology to form a spiral spring sheath 5. This ensures that the cable maintains a spiral spring shape when no external force is applied, giving the cable excellent flexibility and fatigue resistance. At the same time, the spring sheath 5 can effectively resist external compression and wear, protecting all internal structures from physical damage.
