Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a stable control cable. Background Technology

[0002] Control cables have wide applications in many fields, such as industrial automation, power systems, and communication systems, for transmitting control signals and data. In certain environments and applications, externally armored control cables are required. For example, in environments with strong electromagnetic interference, external armor provides excellent electromagnetic shielding, protecting the stable transmission of control signals; in situations requiring the cable to withstand significant mechanical tension, pressure, or frequent bending, armor enhances the cable's mechanical strength and durability.

[0003] However, existing externally armored control cables have some problems. Due to insufficient armor coverage and restraint, the overlapping areas are prone to loosening or gaps when the cable is bent. This not only affects the cable's protective performance but may also damage internal cables, impacting the stability and reliability of signal transmission. To address this issue, some existing technologies increase the overlap area to enhance stability. However, this method has several disadvantages: firstly, it increases material costs and cable manufacturing costs; secondly, it increases the cable's weight, making installation and use more inconvenient; and thirdly, it reduces the cable's flexibility, decreasing its routing flexibility in complex environments. Utility Model Content

[0004] This invention proposes a stable control cable that solves the problem in related technologies where externally armored control cables are prone to loosening or gaps at overlapping points due to insufficient wrapping and constraint when bent.

[0005] The technical solution of this utility model is as follows:

[0006] A stable control cable, comprising:

[0007] cable body,

[0008] An armor tape is spirally wound around the outside of the cable body. The side of the armor tape closest to the cable body is defined as the inside, and the side away from the cable body is defined as the outside. The inside of one side of the armor tape has a pressing part, and the outside of the other side of the armor tape has a pressed part. The armor tape is configured such that after spiral winding, the pressing part abuts against the pressed part.

[0009] As a further technical solution, the pressed part is concave and the pressing part is convex.

[0010] As a further technical solution, the width of the pressed portion along the width direction of the armor belt is greater than the width of the pressing portion, and the pressing portion is configured to slide inside the pressed portion.

[0011] As a further technical solution, the armor belt also has a groove, which is located on one side inside the pressed part.

[0012] As a further technical solution, the outer side of the pressing part has a first reduction groove.

[0013] As a further technical solution, a thin-walled neck is formed between the pressed part and the grooved part.

[0014] As a further technical solution, the outer side of the armor belt has a second reduction groove.

[0015] As a further technical solution, the second reduction groove is located between the first reduction groove and the pressed part, a first positioning ridge is formed between the second reduction groove and the pressed part, and a first friction ridge is formed between the second reduction groove and the first reduction groove.

[0016] As a further technical solution, the armor belt has a third reduction groove inside.

[0017] As a further technical solution, the third reduction groove is located between the groove portion and the pressing portion, and a second friction ridge is formed between the groove portion and the pressing portion.

[0018] The working principle and beneficial effects of this utility model are as follows:

[0019] In this invention, during manufacturing, the armor tape is spirally wound around the cable body. Due to its special design, after the armor tape is spirally wound, the pressing part abuts against the pressed part. This abutting design effectively increases the stability of the armor tape during bending, reduces loosening and gaps at the overlap, and ensures the cable's protective performance. The stable armor structure better protects the internal cable body, reduces the risk of damage to the internal cable, and ensures the stability and reliability of signal transmission. Compared to increasing the overlap area, this structure achieves better stability without significantly increasing material costs and cable weight. It also does not excessively weaken the cable's flexibility, allowing it to maintain high flexibility in wiring in complex environments. Attached Figure Description

[0033] Example 1

[0034] Reference Figures 1-3 This is the first embodiment of the present invention, which proposes a stable control cable, including a cable body 1 and an armor tape 2 spirally wound around the outside of the cable body 1. The side of the armor tape 2 close to the cable body 1 is defined as the inside, and the side away from the cable body 1 is defined as the outside. The inside of one side of the armor tape 2 has a pressing part 201, and the outside of the other side of the armor tape 2 has a pressed part 202. The armor tape 2 is configured such that after spiral winding, the pressing part 201 and the pressed part 202 abut against each other.

[0035] In this embodiment, during the manufacturing process, the armor tape 2 is spirally wound around the cable body 1. Due to its special design, after the armor tape 2 is spirally wound, the pressing part 201 abuts against the pressed part 202. This abutting design between the pressing part 201 and the pressed part 202 effectively increases the stability of the armor tape 2 during bending, reduces loosening and gaps at the overlap, and ensures the cable's protective performance. The stable armor structure can better protect the internal cable body 1, reduce the risk of damage to the internal cable, and ensure the stability and reliability of signal transmission. Compared to increasing the overlap area, this structure achieves better stability without significantly increasing material costs and cable weight. It also does not excessively weaken the cable's flexibility, allowing it to maintain high flexibility in wiring in complex environments.

[0036] Furthermore, the pressed part 202 is concave, and the pressing part 201 is convex.

[0037] In this embodiment, during the spiral winding of the armor tape 2 around the cable body 1, the convex pressing part 201 naturally embeds into the concave pressed part 202, forming a tight fit. The convex pressing part 201 and the concave pressed part 202 achieve a tighter fit, further enhancing the stability of the overlapping area of ​​the armor tape 2 and reducing loosening and gaps. This concave-convex fit design facilitates precise positioning of the pressing part 201 and the pressed part 202 during winding, improving production efficiency and quality consistency. The tighter fit provides better protection, effectively preventing external factors from affecting the internal cable body 1. The concave-convex fit structure ensures a more uniform force distribution on the armor tape 2 when subjected to external forces, reducing the risk of localized damage.

[0038] Furthermore, the width of the pressed portion 202 along the width direction of the armor belt 2 is greater than the width of the pressing portion 201, and the pressing portion 201 is configured to slide inside the pressed portion 202.

[0039] In this embodiment, when the cable is bent, the sliding of the pressing part 201 within the pressed part 202 better adapts to the changes in bending, reducing damage caused by localized stress concentration. This sliding design ensures good contact and stability at the overlapping point of the armor tape 2 under different degrees and directions of bending. It effectively disperses the stress generated during bending, preventing stress concentration at a single point, thereby improving the cable's bending resistance. It reduces the risk of fatigue damage to the armor tape 2 due to frequent bending, extending the cable's service life. Even in a bent state, it ensures effective contact between the pressing part 201 and the pressed part 202, continuously maintaining good protective performance.

[0040] Furthermore, the armor belt 2 also has a groove 203, which is located on one side inside the pressed part 202.

[0041] In this embodiment, the groove 203 is more easily compressed when the cable is bent. Due to its special structure, it can deform during bending, thus adapting to the cable's bending. The groove 203 can effectively adapt to the deformation during cable bending, reducing internal stress and structural damage caused by bending. This helps improve the cable's flexibility, allowing it to bend more flexibly in scenarios requiring bending without affecting its performance. It maintains the overall stability of the armor strip 2 during bending, preventing the connection between the pressing part 201 and the pressed part 202 from loosening due to deformation. Even in a bent state, it ensures good protection for the internal cable body 1, reducing interference from external factors on signal transmission.

[0042] Furthermore, the outer side of the pressure section 201 has a first reduction groove 204.

[0043] In this embodiment, the first reduction groove 204 does not directly participate in obvious actions during normal use, bending, or when the cable is subjected to other external forces, but its presence affects the structural characteristics of the pressure section 201. The first reduction groove 204 reduces the material used in the pressure section 201, thereby reducing the overall weight of the cable and facilitating installation and transportation. It helps increase the flexibility of the pressure section 201, making the cable more flexible when bending and reducing bending resistance. It can change the stress distribution of the pressure section 201 under stress, reducing stress concentration and improving the cable's durability. While reducing weight and increasing flexibility, it does not affect the stability of the contact between the pressure section 201 and the pressed section 202, ensuring the cable's protective performance.

[0044] Furthermore, a thin-walled neck 205 is formed between the pressed portion 202 and the recessed portion 203.

[0045] In this embodiment, during normal use, bending, or when subjected to external forces, the thin-walled neck 205 deforms accordingly with the cable's deformation. The thinner structure of the neck 205 allows it to deform more easily when the cable bends, thus better adapting to the cable's bending motion. It acts as a stress buffer, reducing stress concentration between the compressed portion 202 and the recessed portion 203, protecting the structural integrity of the armor strip 2. During deformation, it helps maintain the connection stability between the compressed portion 202 and the recessed portion 203, ensuring that the protective function of the armor strip 2 is not affected. Through a reasonable structural design, the strength and durability of the armor strip 2 in critical areas are improved without significantly increasing the material usage.

[0046] Example 2

[0047] Reference Figures 4-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0048] Compared to Embodiment 1, the armor belt 2 further has a second reduction groove 206 on its exterior.

[0049] In this embodiment, the second weight-reducing groove 206 significantly reduces the overall weight of materials and the cable, lowering costs. This is particularly suitable for applications with less stringent weight and cost requirements and less demanding environments. When the cable is laid in an environment with smooth inner walls, such as a conduit, the second weight-reducing groove 206 ensures a closer and more stable contact between the cable and the inner wall, reducing the possibility of slippage and displacement. It also improves the cable's bending flexibility, making it easier to adapt to different layout requirements during installation and use. Reducing material coverage increases the heat dissipation area to some extent, which is beneficial for heat dissipation during operation and reduces the risk of overheating. While reducing weight and saving materials, it still provides necessary protection for the internal cable body 1, ensuring the stability of signal transmission.

[0050] Furthermore, the second reduction groove 206 is located between the first reduction groove 204 and the pressed part 202, a first positioning ridge 207 is formed between the second reduction groove 206 and the pressed part 202, and a first friction ridge 208 is provided between the second reduction groove 206 and the first reduction groove 204.

[0051] In this embodiment, these structural features work together during normal use, bending, or when the cable is subjected to external forces. The first positioning ridge 207 helps determine the position and orientation of the armor strip 2 during assembly and use, while the first friction ridge 208 increases the friction between adjacent parts, helping to maintain structural stability. The first positioning ridge 207 provides accurate positioning during cable installation and use, ensuring the correct position of the armor strip 2 and maintaining cable performance and protection. The first friction ridge 208 increases friction between adjacent parts, preventing relative slippage during use and improving the overall stability of the cable. The rationally distributed reduction grooves and edge structure reduce weight while optimizing the stress distribution of the armor strip 2, improving its ability to withstand external forces. The reduction grooves reduce material usage and lower production costs without affecting the cable's function and quality. The stable structure and precise positioning help improve the reliability of the cable in various complex environments, ensuring stable signal transmission.

[0052] Example 3

[0053] Reference Figures 6-7 This is the third embodiment of the present invention, which differs from the previous two embodiments in that:

[0054] Furthermore, the armor belt 2 has a third reduction groove 209 inside.

[0055] Furthermore, the third reduction groove 209 is located between the groove portion 203 and the pressure portion 201, and a second friction ridge 210 is formed between the groove portion 203 and the pressure portion 201.

[0056] In this embodiment, during the manufacturing and use of the cable, the third reduction groove 209 provides greater deformation space for the armor tape 2. When the armor tape 2 is wrapped around the cable body 1, the third reduction groove 209 allows the armor tape 2 to more easily adapt to the shape and size of the cable body 1. Simultaneously, the second friction ridge 210 increases the friction between the various parts inside the armor tape 2, helping to maintain the positional stability of the armor tape 2 on the cable body 1. The third reduction groove 209 significantly reduces the weight of the armor tape 2, lowering material costs while meeting the requirement for substantial weight reduction. Furthermore, this structure makes it easier and more tightly the armor tape 2 wraps around the smooth surface of the cable body 1, improving the efficiency and quality of the wrapping. The second friction ridge 210 increases internal friction, preventing the armor tape 2 from sliding or shifting during use, further enhancing the structural stability of the cable. This helps simplify the cable manufacturing process, improve production efficiency, and reduce production costs.
