Summary of the Invention

[0003] In order to avoid cracks in the cable when it is bent at a large angle and to increase the service life of the cable, the present application provides an industrial flexible cable.

[0004] The industrial flexible cable provided in this application adopts the following technical solution:

[0005] An industrial flexible cable includes: a wire body, the wire body including a signal wire, an insulation layer and a protective layer, the insulation layer is coated on the outside of the signal wire, the protective layer is sleeved on the outside of the insulation layer, the insulation layer and the protective layer are spaced apart, and a first accommodation gap is defined between the insulation layer and the protective layer.

[0007] By adopting the above technical solution, by sequentially and spaced apart along the circumference of the cable, when the cable is bent, the protective layer squeezes the airbags facing away from the cable's bend, causing the gas in those airbags to flow into those facing the cable's bend, thereby expanding the airbags facing the cable's bend and preventing the cable from bending at large angles. Compared to existing technologies, this application can minimize the risk of large-angle bending in the cable, thereby minimizing the risk of cracks in the cable, and thus increasing the cable's service life.

[0008] Preferably, the anti-bending component also includes a plurality of fixing frames, which are arranged at intervals along the length direction of the wire body, and the plurality of fixing frames are arranged in one-to-one correspondence with the plurality of airbag groups, and the fixing frames are suitable for elastic deformation, and the fixing frames are provided with a receiving groove, and the airbag group is arranged in the receiving groove, and the bottom wall of the receiving groove is provided with a plurality of extrusion parts, and the plurality of extrusion parts are arranged at intervals along the circumferential direction of the wire body, and the plurality of extrusion parts are arranged in one-to-one correspondence with the plurality of airbags, and when the wire body bends, the extrusion parts that deviate from the bending direction of the wire body squeeze the corresponding airbags.

[0009] By adopting the above technical solution, the extrusion part can extrude the corresponding airbag more accurately. Compared with squeezing the airbag facing away from the bending direction of the wire body through the protective layer, this arrangement does not require the protective layer to squeeze the airbag after the wire body is bent to a certain extent, thereby enabling the airbag facing the bending direction of the wire body to expand more quickly and prevent the wire body from bending at a large angle.

[0015] By adopting the above technical solution, when the sheath is impacted by external force, the sheath applies a force toward the inside of the line body to the buffer, and then the buffer elastically deforms and gradually absorbs the force applied by the sheath on the buffer, thereby minimizing the damage to the signal line caused by the impact of external force, thereby improving the working reliability of the industrial flexible cable.

[0017] By adopting the above technical solution, when the sheath applies a force toward the inside of the wire body to the buffer, the first buffer part and the second buffer part are both compressed and deformed toward the inside of the wire body to gradually absorb the force applied by the sheath to the buffer, thereby achieving the technical effect of buffering the impact of external forces on the wire body through the buffer.

[0018] Preferably, the outer wall of the sheath is provided with a thermochromic coating.

[0019] By adopting the above technical solution, when the surface temperature of the sheath reaches the preset color-changing temperature of the thermochromic coating, the thermochromic coating changes color.

[0040] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0041] The embodiment of the present application discloses an industrial flexible cable 100 .

[0042] Reference Figure 1-Figure 3According to an embodiment of the present application, an industrial flexible cable 100 includes a cable body 1 and a bending-resistant component 2. The cable body 1 includes a signal line 11, an insulating layer 12, and a protective layer 13. The insulating layer 12 is coated on the outside of the signal line 11, and the protective layer 13 is sleeved on the outside of the insulating layer 12. Along the radial direction of the cable body 1, the insulating layer 12 and the protective layer 13 are spaced apart, and a first accommodating gap 131 is defined between the outer peripheral wall of the insulating layer 12 and the inner peripheral wall of the protective layer 13. That is, along the radial direction of the cable body 1 from the inside to the outside, the insulating layer 12 is located on the outside of the signal line 11, and the protective layer 13 is located on the outside of the insulating layer 12.

[0043] In some specific embodiments, the signal line 11 may be formed by twisting 48 thin copper wires.

[0044] In some specific embodiments, the material of the insulating layer 12 may be polyimide, and the material of the protective layer 13 may be polyetheretherketone, but the present application is not limited thereto. The material of the insulating layer 12 may be polytetrafluoroethylene, etc., and the material of the protective layer 13 may be thermoplastic polyurethane, etc.

[0045] The anti-bending component 2 is sandwiched between the insulating layer 12 and the protective layer 13. The anti-bending component 2 includes a plurality of airbag groups 21. The plurality of airbag groups 21 are spaced apart along the length direction of the wire body 1. The length direction of the wire body 1 can refer to Figure 1 In the front-to-back direction, the airbag group 21 includes a plurality of airbags 211, and the plurality of airbags 211 are arranged in sequence and spaced apart along the circumferential direction of the wire body 1. The airbags 211 are stopped against the insulating layer 12 and the protective layer 13. Each airbag 211 is filled with gas, and when the wire body 1 is not bent, each airbag 211 is in an incompletely expanded state. Any two adjacent airbags 211 are connected, that is, the gas in one airbag group 21 can flow between the plurality of airbags 211 in the corresponding airbag group 21. When the wire body 1 is bent, the airbag 211 facing the bending direction of the wire body 1 is suitable for expansion, and the airbag 211 facing away from the bending direction of the wire body 1 is suitable for contraction.

[0046] Specifically, when the wire body 1 is bent, the protective layer 13 squeezes the airbag 211 facing away from the bending direction of the wire body 1, the airbag 211 facing away from the bending direction of the wire body 1 shrinks, and the gas in the airbag 211 facing away from the bending direction of the wire body 1 flows into the airbag 211 facing the bending direction of the wire body 1, so that the airbag 211 facing the bending direction of the wire body 1 expands, and the expansion of the airbag 211 facing the bending direction of the wire body 1 prevents the wire body 1 from bending at a large angle.

[0047] In some specific embodiments, along the first direction of the line body 1, the first direction of the line body 1 may refer to Figure 1In the left and right directions, when the wire body 1 bends toward the right, the airbag 211 located on the left side of the wire body 1 is squeezed and compressed by the protective layer 13, and the gas in the airbag 211 located on the left side of the wire body 1 flows into the airbag 211 located on the right side of the wire body 1, so that the airbag 211 located on the right side of the wire body 1 expands. After the airbag 211 located on the right side of the wire body 1 expands, it prevents the wire body 1 from bending at a large angle toward the right.

[0048] When the wire body 1 recovers from a bent state to an unbent state, the airbags 211 toward the bending direction of the wire body 1 are squeezed by the protective layer 13, the airbags 211 toward the bending direction of the wire body 1 shrink, and the gas in the airbags 211 toward the bending direction of the wire body 1 flows to the airbags 211 away from the bending direction of the wire body 1, so that the multiple airbags 211 are restored to their initial state.

[0049] Thus, by sequentially and spaced apart along the circumferential direction of the cable body 1, when the cable body 1 is bent, the protective layer 13 squeezes the airbags 211 facing away from the bending direction of the cable body 1, and the gas in the airbags 211 facing away from the bending direction of the cable body 1 flows into the airbags 211 facing the bending direction of the cable body 1, thereby causing the airbags 211 facing the bending direction of the cable body 1 to expand and prevent the cable body 1 from bending at a large angle. Compared with the prior art, the present application can minimize the occurrence of large-angle bending in the cable, thereby minimizing the occurrence of cracks in the cable, and thus improving the service life of the cable.

[0050] Reference Figure 1 、 Figure 2 and Figure 5 In some embodiments of the present application, the anti-bending component 2 may further include a plurality of fixing frames 22, which are spaced apart along the length direction of the wire body 1, and the plurality of fixing frames 22 are arranged in one-to-one correspondence with the plurality of airbag groups 21, and the fixing frames 22 are suitable for elastic deformation, and the fixing frames 22 are provided with a receiving groove 221, and the airbag group 21 is arranged in the receiving groove 221, and the bottom wall of the receiving groove 221 is provided with a plurality of extrusion parts 225, and the plurality of extrusion parts 225 are spaced apart along the circumferential direction of the wire body 1, and the plurality of extrusion parts 225 are arranged in one-to-one correspondence with the plurality of airbags 211. When the wire body 1 bends, the extrusion parts 225 facing away from the bending direction of the wire body 1 squeeze the corresponding airbags 211.

[0051] Specifically, when the wire body 1 is bent, the extrusion portion 225 facing away from the bending direction of the wire body 1 squeezes the corresponding airbag 211, so that the airbag 211 facing away from the bending direction of the wire body 1 is compressed, and the gas in the airbag 211 facing away from the bending direction of the wire body 1 flows into the airbag 211 facing the bending direction of the wire body 1, so that the airbag 211 facing the bending direction of the wire body 1 expands and prevents the wire body 1 from bending at a large angle.

[0052] Moreover, the extrusion portion 225 can more accurately extrude the corresponding airbag 211. Compared with the extrusion of the airbag 211 facing away from the bending direction of the wire body 1 through the protective layer 13, this arrangement does not require the protective layer 13 to extrude the airbag 211 after the wire body 1 is bent to a certain extent, thereby enabling the airbag 211 facing the bending direction of the wire body 1 to expand more rapidly and prevent the wire body 1 from bending at a large angle.

[0053] In some specific embodiments, the receiving groove 221 may be open toward the insulating layer 12 . In other specific embodiments, the receiving groove 221 may be open toward the protective layer 13 .

[0054] In some specific embodiments, the fixing frame 22 may be made of nylon material, but the present application is not limited thereto. The fixing frame 22 may also be made of materials such as thermoplastic polyurethane.

[0055] It should be noted that the fixing frame 22 can be connected end to end to form a fixing frame 22 having a ring shape, and the shape of the airbag assembly 21 is also ring-shaped.

[0057] In some specific embodiments, the accommodating groove 221 is open toward the insulating layer 12, and the snap-fitting protrusion 222 is located on the end wall of the fixing frame 22 close to the insulating layer 12. The snap-fitting protrusion 222 is snap-fitted with the end wall of the airbag 211 away from the extrusion portion 225, thereby achieving the technical effect of fixedly connecting multiple airbags 211 and the fixing frame 22. When the airbag 211 is installed in the fixing frame 22, the operator can directly press the airbag 211 into the accommodating groove 221 by hand, thereby increasing the installation speed of the airbag 211 and further increasing the production efficiency of the industrial flexible cable 100.

[0058] Furthermore, along the length direction of the wire body 1 , a plurality of latching protrusions 222 are provided at the front end portion of the fixing frame 22 and the rear end portion of the fixing frame 22 .

[0059] Reference Figure 4 and Figure 5In some embodiments of the present application, a plurality of limiting portions 223 are provided in the accommodating groove 221. Specifically, the limiting portion 223 can be provided on the inner side wall of the accommodating groove 221. The plurality of limiting portions 223 are spaced apart along the circumferential direction of the linear body 1. A limiting gap 224 is defined between any two adjacent limiting portions 223. Each limiting gap 224 is provided with an airbag 211, and the airbag 211 is limitedly matched with the limiting portion 223. That is, the airbag 211 is clamped between any two adjacent limiting portions 223.

[0060] By cooperating with the airbag 211 and the limiting portion 223, the airbag 211 can be prevented from moving in the circumferential direction of the wire body 1, and the airbag 211 can be prevented from deviating from the preset position, resulting in the absence of the airbag 211 in a local area of ​​the wire body 1. The wire body 1 can be prevented from being bent at a large angle when it is bent, resulting in cracks in the wire body 1.

[0061] In some specific embodiments, one limiting gap 224 may be provided with one airbag 211 . In other specific embodiments, one limiting gap 224 may be provided with multiple airbags 211 , and the multiple airbags 211 are all provided to abut against each other.

[0062] Furthermore, along the length direction of the wire body 1 , a plurality of limiting portions 223 are provided on the front inner side wall of the accommodating groove 221 and the rear inner side wall of the fixing frame 22 .

[0063] Reference Figure 1 and Figure 2 In some embodiments of the present application, the industrial flexible cable 100 may further include: a buffer 3, the wire body 1 may further include a sheath 14, along the radial direction of the wire body 1, the sheath 14 is sleeved on the outside of the insulating layer 12, the inner circumferential wall of the sheath 14 is spaced apart from the outer circumferential wall of the insulating layer 12, and a second accommodating gap 141 is defined between the sheath 14 and the insulating layer 12, the buffer 3 is clamped between the sheath 14 and the insulating layer 12, the buffer 3 extends along the length direction of the wire body 1, and the buffer 3 and the inner circumferential wall of the sheath 14 and the outer circumferential wall of the insulating layer 12 are all stopped, the buffer 3 is suitable for elastic deformation, and the buffer 3 is used to separate the sheath 14 and the insulating layer 12.

[0064] Specifically, when the sheath 14 is impacted by external force, the sheath 14 applies a force toward the inside of the wire body 1 to the buffer 3, and then the buffer 3 elastically deforms and gradually absorbs the force applied by the sheath 14 on the buffer 3, thereby minimizing the signal line 11 from being impacted by external force and causing damage to the signal line 11, thereby improving the working reliability of the industrial flexible cable 100.

[0065] Furthermore, the sheath 14 and the anti-slip layer can play a dual protective role. When the sheath 14 is damaged, the protective layer 13 can also protect the signal line 11.

[0066] In some specific embodiments, the material of the sheath 14 may be polyetheretherketone, but the present application is not limited thereto. The material of the sheath 14 may be thermoplastic polyurethane or the like.

That is to say, a second buffer portion 32 is provided between any two adjacent first buffer portions 31, and a first buffer portion 31 is provided between any two adjacent second buffer portions 32, and the adjacent first buffer portions 31 and second buffer portions 32 are fixedly connected.

[0068] It should be noted that the connection between the adjacent first buffer portion 31 and the second buffer portion 32 may be located on the side close to the sheath 14 or on the side close to the protective layer 13 .

[0069] In addition, there is an angle between the first buffer portion 31 and the second buffer portion 32, and the connection between the first buffer portion 31 and the second buffer portion 32 stops at the insulation layer 12 and / or the sheath 14. In some specific embodiments, the connection between the first buffer portion 31 and the second buffer portion 32 stops at both the insulation layer 12 and the sheath 14.

[0070] Specifically, when the sheath 14 applies a force toward the inside of the wire body 1 to the buffer 3, the first buffer portion 31 and the second buffer portion 32 are both compressed and deformed toward the inside of the wire body 1 to gradually absorb the force applied by the sheath 14 to the buffer 3, thereby achieving the technical effect of buffering the impact of external forces on the wire body 1 through the buffer 3.

[0077] Specifically, the operating parameters of the signal line 11 are detected by the detection sensor 121, and then the detection sensor 121 sends the operating parameters of the signal line 11 to the monitoring device. The operator can understand the operating status of the industrial flexible cable 100 through the monitoring device. The operator does not need to go to the installation location of the industrial flexible cable 100 to check and detect the operating status of the industrial flexible cable 100, which can reduce the work intensity of the operator and improve the user experience of the industrial flexible cable 100.
