Description

Technical Field

[0001] This utility model relates to the field of high-temperature flame-retardant cable technology, and in particular to a high-temperature flame-retardant cable for industrial intelligent equipment. Background Technology

[0002] In the field of communications, with the rapid development of information technology, the performance requirements for communication cables are becoming increasingly stringent. Traditional communication cables have revealed a series of problems in practical applications, severely restricting communication quality, stability, and the cable's own service life and adaptability.

[0003] Signal interference problem

[0004] Severe internal crosstalk: Traditional communication cables have multiple conductors tightly packed together, lacking effective isolation structures, making signals highly susceptible to interference during transmission, i.e., frequent crosstalk. In today's high-speed data transmission, this crosstalk can distort signals, increase the bit error rate, and severely affect the accuracy and integrity of data transmission, reducing communication efficiency. For example, crosstalk is particularly prominent in scenarios with a large number of cables densely packed within data centers, causing errors in data exchange between servers and affecting the operation of the entire data center.

[0005] Weak resistance to external interference: Communication cables are typically laid in complex electromagnetic environments, and traditional cables are insufficiently resistant to external electromagnetic interference. External electromagnetic radiation and interference from electrical equipment can affect the normal transmission of signals within the cable, leading to communication interruptions or signal quality degradation. In areas near large substations or industrial equipment, external interference to communication cables is even more severe, affecting the normal operation of surrounding communication equipment.

[0006] Mechanical performance issues

[0007] Easily broken and damaged: Traditional communication cables are prone to internal conductor breakage when bent, stretched, or subjected to external impact. The bending radius of cables is relatively limited; excessive bending can cause stress concentration and breakage of the conductors, leading to communication interruptions. Furthermore, during installation and maintenance, cables may be subjected to unexpected pulling, squeezing, or other external forces. The structure of traditional cables cannot effectively withstand these forces, easily causing damage to the cable sheath and internal conductors, increasing maintenance costs and the risk of communication failures.

[0008] The trade-off between flexibility and support: To ensure cable flexibility and adaptability to different wiring environments, traditional cables often sacrifice some support strength in their structural design. However, cables lacking sufficient support are prone to deformation and twisting in practical use, further affecting the stability of signal transmission. For example, in situations requiring frequent cable movement, such as communication cables in stage lighting control systems, the imbalance between flexibility and support makes the cables susceptible to damage, affecting the accuracy of lighting control.

[0009] Stability issues

[0010] Poor connection stability: Traditional communication cables, lacking a robust fixing structure, are prone to loosening when connected to communication equipment due to external vibrations, temperature changes, or slight pulling, leading to unstable signal transmission. This can have serious consequences in scenarios with extremely high communication stability requirements, such as financial trading systems and aviation communication systems, including data loss and flight safety hazards.

[0011] Internal structure is prone to change: During long-term use, especially in environments with significant temperature and humidity fluctuations, the internal structure of cables is susceptible to changes. Misalignment of conductor positions and aging or deformation of the insulation layer can affect the stability of signal transmission and reduce the cable's lifespan.

[0012] High temperature resistance issues

[0013] High temperatures affect signal transmission: During operation, communication cables generate heat due to the flow of current, especially when multiple cables are densely laid or under high load, causing a significant temperature increase. Traditional cables have insufficient high-temperature resistance; high temperatures degrade the cable's insulation performance and increase conductor resistance, thus affecting the quality and speed of signal transmission. In communication equipment rooms with poor heat dissipation, signal transmission problems caused by high temperatures are common.

[0014] Accelerated cable aging: High temperatures accelerate the aging process of cable sheaths, insulation layers, and other components. Traditional cable materials tend to harden and become brittle at high temperatures, losing their original flexibility and insulation properties, shortening cable lifespan, and increasing replacement costs. Utility Model Content

[0015] (a) Technical problems to be solved

[0016] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant and flame-retardant cable for industrial intelligent equipment, solving the technical problems of significant deficiencies in signal interference protection, mechanical performance, stability, and high-temperature resistance of existing communication cables.

[0017] (II) Technical Solution

[0018] To achieve the above objectives, this utility model provides the following technical solution:

[0019] A high-temperature resistant and flame-retardant cable for industrial intelligent equipment includes a flame-retardant cable, which includes a cable sheath, a cable body, and a separator frame. The separator frame has at least two V-shaped grooves on its outer side, and each cable body is located in a V-shaped groove. The separator frame has an inner groove at its center, and the separator frame is equipped with reinforcing ribs through the inner groove.

[0020] Preferably, the outer sheath of the cable is wrapped with an inner sheath, which is wrapped around the separator frame. Each side wall of the separator frame is provided with an arc-shaped groove, and each arc-shaped groove is provided with a conical groove in sections.

[0021] Preferably, the cable body is further distributed in the arc-shaped groove opened in the separator frame, the inside of the cable body is wrapped with a heat-resistant layer, and the inside of the heat-resistant layer is wrapped with the cable core.

[0022] (III) Beneficial Effects

[0023] 1. When flame-retardant cables are used to connect intelligent devices, the outer and inner sheaths of the cable protect multiple cable bodies. The internal separators of the flame-retardant cable can separate and protect multiple cable bodies, effectively isolating signal interference between each cable body. The separators can also provide tough support for multiple cable bodies, effectively preventing them from breaking when bent. At the same time, the reinforcing ribs inside the separators can provide a certain degree of fixation, improve the anti-cutting ability of the separators, and assist the separators in bending, ensuring the bending angle during transmission.

[0024] Second, the position of the cable body inside the cable sheath will not change due to bending, improving the stability of the intelligent device when connected to the wire harness. At the same time, the arc-shaped groove is divided into sections with conical grooves, which can wrap the cable body more tightly in sections. After the flame-retardant cable is cut into sections, the cable body inside the cable sheath will not loosen. In addition, an inner cable sheath is set between the outer cable sheath and the cable body, which can improve the high temperature resistance of the cable body. At the same time, a heat-resistant layer is set between the cable body and the cable core, further improving the high temperature resistance of the cable core. Attached Figure Description

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the overall concept of the technical solution in this application embodiment is as follows:

[0032] To address the problems existing in the prior art, this utility model provides a high-temperature resistant and flame-retardant cable for industrial intelligent equipment, including a flame-retardant cable 22. The flame-retardant cable 22 includes a cable sheath 1, a cable body 18, and a separator frame 13. At least two V-shaped grooves 14 are opened on the outer side of the separator frame 13, and each cable body 18 is located in the V-shaped groove 14. An inner groove 16 is opened at the center of the separator frame 13, and a reinforcing rib 17 is installed on the separator frame 13 through the inner groove 16.

[0033] The cable outer sheath 1 is wrapped with a cable inner sheath 11, which is wrapped around the separator frame 13. Each side wall of the separator frame 13 is provided with an arc-shaped groove 15, and each arc-shaped groove 15 is divided into sections with conical grooves 21. The cable body 18 is further distributed in the arc-shaped grooves 15 of the separator frame 13. The inside of the cable body 18 is wrapped with a heat-resistant layer 19, and the inside of the heat-resistant layer 19 is wrapped with a cable core 2.

[0034] Working principle:

[0035] The first step involves the use of flame-retardant cables 22 during the operation of industrial intelligent equipment. When the flame-retardant cable 22 is connected to the intelligent equipment, the outer sheath 1 and the inner sheath 11 of the cable wrap around and protect multiple cable bodies 18. The separator 13 inside the flame-retardant cable 22 can separate and protect multiple cable bodies 18, effectively isolating signal interference between each cable body 18. The separator 13 can also provide tough support for multiple cable bodies 18, effectively preventing multiple cable bodies 18 from breaking when bending. At the same time, the reinforcing ribs 17 inside the separator 13 can provide a certain fixing capacity, and the reinforcing ribs 17 can improve the anti-cutting ability of the separator 13. The reinforcing ribs 17 can also assist the separator 13 in bending, ensuring the bending angle during transmission.

[0036] The second step involves creating an arc-shaped groove 15 within the separator 13, which perfectly fits the cable body 18, ensuring that the position of the cable body 18 within the cable sheath 1 does not change due to bending, thus improving the stability of the intelligent device during wire harness connection. Simultaneously, the arc-shaped groove 15 is segmented with conical grooves 21, which can wrap the cable body 18 more tightly in segments. Even after the flame-retardant cable 22 is cut into segments, the cable body 18 within the cable sheath 1 will not loosen. Furthermore, an inner cable sheath 11 is provided between the cable sheath 1 and the cable body 18, which can improve the high-temperature resistance of the cable body 18. Additionally, a heat-resistant layer 19 is provided between the cable body 18 and the cable core 2, further enhancing the high-temperature resistance of the cable core 2.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
