Description

Technical Field

[0001] This invention belongs to the field of cable technology, and particularly relates to a bending and torsion resistant cable and a method for producing the bending and torsion resistant cable. Background Technology

[0002] Cables are essential electrical materials used for power transmission and signal transmission, consisting of one or more conductors and their insulating protective layers. To improve the cable's resistance to bending and torsion, a reinforcing layer or armor layer is usually placed on the outer surface of the cable to enhance its mechanical strength and provide additional protection against external physical damage.

[0003] Due to the increased mechanical strength of the cables, their bending difficulty has also increased significantly, making it impossible to organize and arrange them in an orderly manner. This makes storage and transportation inconvenient, as well as cable installation. Summary of the Invention

[0004] To address the problems in the prior art, the present invention proposes the following technical solution:

[0005] A bending and torsion resistant cable includes: a reinforcing assembly, the reinforcing assembly including a supporting inner layer, a supporting outer layer and an adjusting member, a plurality of reinforcing strips are circumferentially arranged between the supporting inner layer and the supporting outer layer, a plurality of adjusting grooves are equidistantly arranged on the outer side of the reinforcing strips, and a reinforcing sheet is movably inserted into the adjusting groove;

[0006] The cable is bent by adjusting the position of the slot for bending and winding. After the cable is placed, several reinforcing plates are moved by the adjusting member and inserted into the corresponding adjusting slot. The reinforcing strip and multiple reinforcing plates support the cable circumferentially, increasing the mechanical strength of the cable and improving its resistance to bending and torsion.

[0007] As a preferred embodiment of the above technical solution, the adjusting component includes multiple hollow hoses, each hollow hose having connecting wings on both sides, and multiple telescopic branches equidistantly arranged in the middle of the hollow hose, with one end of each telescopic branch fixedly connected to the surface of the reinforcing sheet.

[0008] As a preferred embodiment of the above technical solution, the end of the reinforcing sheet is convex, and the adjustment groove is stepped to match it.

[0009] As a preferred embodiment of the above technical solution, the bottom of the reinforcing strip is fixedly connected to the outer surface of the inner support layer, and the reinforcing strip and the inner support layer are integrally formed.

[0010] As a preferred embodiment of the above technical solution, the two connecting wings of the hollow hose are respectively fixedly connected to the outer side of the corresponding reinforcing strip, and the connecting wings of two adjacent hollow hoses are fitted together.

[0011] As a preferred embodiment of the above technical solution, the reinforcing component further includes an elastic layer located inside the supporting inner layer, the elastic layer being used to restore a bent cable.

[0012] As a preferred embodiment of the above technical solution, it further includes: a core body, wherein an insulation layer and a braided shielding layer are sequentially sleeved on the outside of the core body, and the elastic layer is sleeved on the surface of the braided shielding layer.

[0013] A method for producing a bend- and torsion-resistant cable includes the following steps:

[0014] S1, covering elastic layer;

[0015] After the wire core body, which is covered with insulation and braided shielding, passes through the processing position, the elastic layer material in the molten state is extruded through the corresponding mold to tightly wrap around the wire core body;

[0016] S2, inner supporting layer;

[0017] The core body continues to move, and the molten supporting inner layer material is extruded through the corresponding mold to tightly wrap around the core body. At this time, the reinforcing strip and the supporting inner layer are integrally formed.

[0018] S3. Open an adjustment slot;

[0019] Adjustment grooves are opened during or after the curing process of the reinforcing strip, with multiple adjustment grooves equidistantly arranged on the surface of the reinforcing strip.

[0020] S4. Place the adjustment component;

[0021] As the core body continues to move, multiple hollow hoses are placed, and the reinforcing sheet is placed in the adjustment slot position. The connecting wings on both sides of the hollow hoses are attached to the outer surface of the corresponding reinforcing strip to seal the gaps between the reinforcing strips.

[0022] S5, outer supporting layer;

[0023] The core body continues to move, and the molten supporting outer layer material is extruded through the corresponding mold to tightly wrap around the core body. After solidification, the cable production is completed.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The reinforcing strip, together with multiple reinforcing plates, forms a complete support strip to support the cable, ensuring the cable's mechanical strength and giving it strong resistance to bending and torsion. After the reinforcing plates leave the adjustment slot, the cable can be bent through the adjustment slot to complete the winding or placement work, making the cable more convenient to use.

[0026] 2. The adjustment mechanism utilizes the expansion of gas to provide power for the movement of the reinforcing sheet, making the movement of the reinforcing sheet easier. Furthermore, by sealing the hollow flexible tube, the position of the reinforcing sheet can be restricted, preventing displacement of the reinforcing sheet under external force and ensuring the support function of the reinforcing assembly.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings. Example

[0033] Figures 1-4 In the present invention, a bending and torsion resistant cable includes: a reinforcing assembly, the reinforcing assembly including a supporting inner layer 11, a supporting outer layer 12 and an adjusting member 16, wherein a plurality of reinforcing strips 13 are circumferentially arranged between the supporting inner layer 11 and the supporting outer layer 12, and a plurality of adjusting grooves 14 are equidistantly arranged on the outer side of the reinforcing strips 13, and a reinforcing piece 15 is movably inserted into the adjusting groove 14;

[0034] The cable is bent through the adjustment slot 14 for bending and winding. After the cable is placed, the adjustment member 16 moves several reinforcing pieces 15 to insert them into the corresponding adjustment slots 14. The reinforcing strip 13 and the multiple reinforcing pieces 15 support the cable circumferentially, increasing the mechanical strength of the cable and improving its resistance to bending and torsion.

[0035] The bottom of the reinforcing strip 13 is fixedly connected to the outer surface of the inner support layer 11, and the reinforcing strip 13 and the inner support layer 11 are integrally formed.

[0036] After the cable is placed, the adjusting member 16 is used to move several reinforcing plates 15 so that they are inserted into the corresponding adjusting slots 14. The reinforcing strip 13 and the multiple reinforcing plates 15 support the cable circumferentially, increasing the mechanical strength of the cable and improving its resistance to bending and torsion.

[0037] The reinforcing strip 13, together with multiple reinforcing plates 15, forms a complete support strip to support the cable, ensuring the cable's mechanical strength and giving it strong resistance to bending and torsion. After the reinforcing plates 15 leave the position of the adjustment groove 14, the cable can be bent through the adjustment groove 14 to complete the winding or placement work, making the use of the cable more convenient.

[0038] Figures 2-4 In this design, the end of the reinforcing sheet 15 is convex, and the adjustment groove 14 is stepped to match it.

[0039] The end of the reinforcing piece 15 is convex and can cooperate with the adjustment groove 14, which increases the contact area between the reinforcing strip 13 and the reinforcing piece 15 to improve the connection strength between the two, thereby ensuring the mechanical strength of the cable.

[0040] Figures 1-4 In the process, the adjusting component 16 includes a plurality of hollow hoses 161, each hollow hose 161 has a connecting wing 162 on both sides, and a plurality of telescopic branch pipes 163 are equidistantly arranged in the middle of the hollow hose 161, with one end of each telescopic branch pipe 163 being fixedly connected to the surface of the reinforcing sheet 15.

[0041] The two connecting wings 162 of the hollow hose 161 are fixedly connected to the outer side of the corresponding reinforcing strip 13, and the connecting wings 162 of two adjacent hollow hoses 161 are fitted together.

[0042] After sealing one end of the hollow hose 161, gas is introduced into the other end of the hollow hose 161. The telescopic branch pipe 163, which is in a folded state, gradually extends and drives the reinforcing sheet 15 to move. After the reinforcing sheet 15 enters the adjustment groove 14 and completes the installation, this end of the hollow hose 161 is also sealed to prevent the reinforcing sheet 15 from moving.

[0043] The adjustment component 16 utilizes the expansion of gas to provide power for the movement of the reinforcing sheet 15, making the movement of the reinforcing sheet 15 simpler. Furthermore, by sealing the hollow hose 161, the position of the reinforcing sheet 15 can be restricted, preventing the reinforcing sheet 15 from shifting under external force and ensuring the support function of the reinforcing assembly.

[0044] Figure 1 The reinforcement component further includes an elastic layer 17 located inside the support inner layer 11, the elastic layer 17 being used to straighten a bent cable.

[0045] The elastic layer 17 provides a restoring force to the bent cable, allowing the cable to automatically return to its original position and facilitating the installation of the reinforcing sheet 15.

[0046] Figure 1 The device also includes: a core body 20, an insulation layer 30 and a braided shielding layer 40 sequentially sleeved on the outside of the core body 20, and an elastic layer 17 sleeved on the surface of the braided shielding layer 40.

[0047] A method for producing a bend- and torsion-resistant cable includes the following steps:

[0048] S1, covering elastic layer 17;

[0049] The core body 20, which is covered with insulation layer 30 and braided shielding layer 40, is processed through a corresponding mold, and the molten elastic layer 17 material is extruded to tightly wrap around the core body 20.

[0050] S2, inner supporting layer 11;

[0051] The core body 20 continues to move, and the molten supporting inner layer 11 material is extruded through the corresponding mold to tightly wrap around the core body 20. At this time, the reinforcing strip 13 and the supporting inner layer 11 are integrally formed.

[0052] S3. Open adjustment slot 14;

[0053] During or after the curing process of the reinforcing strip 13, adjustment grooves 14 are opened, and multiple adjustment grooves 14 are equidistantly arranged on the surface of the reinforcing strip 13.

[0054] S4, Place adjustment component 16;

[0055] As the core body 20 continues to move, multiple hollow hoses 161 are placed, and the reinforcing sheet 15 is placed in the adjustment groove 14. The connecting wings 162 on both sides of the hollow hose 161 are attached to the outer surface of the corresponding reinforcing strip 13 to seal the gap between the reinforcing strips 13.

[0056] S5, outer supporting layer 12;

[0057] The core body 20 continues to move, and the molten supporting outer layer 12 material is extruded through the corresponding mold to tightly wrap around the core body 20. After solidification, the cable production is completed.

[0058] In this technical solution, the inner side of the inner support layer 11 and the outer support layer 12 are sequentially wrapped and formed, which facilitates the insertion of the adjustment component 16 between the two processes. The adjustment component 16 can seal the gap between the reinforcing strips 13, preventing the outer support layer 12 from entering during the wrapping process and affecting the forming of the reinforcing component.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
