Description

Technical Field

[0001] This utility model relates to the field of drag chain cable technology, specifically a bend-resistant and highly flexible drag chain cable. Background Technology

[0002] In scenarios where mobile equipment units require reciprocating motion, to prevent cables from tangling, abrasion, pull-out, snagging, or scattering, they are typically integrated into a cable chain system, allowing them to move synchronously with the cable chain under protected conditions. Cables of this type, which need to adapt to dynamic operating environments and possess high bending resistance, are defined as cable chain cables. Given their special characteristic of needing to withstand frequent movement over long periods, the cable's flexibility, tensile strength, and abrasion resistance become key performance indicators, directly affecting its service life.

[0003] Existing drag chain cables improve tensile strength through filler layer design, but a significant performance contradiction exists: while excessive filler can enhance the radial stability of the conductor, it hinders heat conduction. Research indicates that although filler materials can assist in heat dissipation under certain conditions, excessive filler forms a thermal resistance barrier, leading to increased internal temperature rise and decreased heat dissipation efficiency during continuous high-load operation. Conversely, insufficient filler, while reducing the thermal resistance effect, makes it difficult to maintain the stability of the conductor geometry. Utility Model Content

[0004] The purpose of this invention is to provide a bend-resistant, highly flexible drag chain cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bend-resistant and highly flexible drag chain cable, comprising a protective sheath and a cable core body, wherein the protective sheath is provided with clamping components at equal intervals, the cable core body is provided with the clamping components at equal intervals on its peripheral side, and the clamping components are also provided with auxiliary bending components.

[0006] Preferably, in order to improve the performance of the cable during use, the protective sleeve includes a protective sleeve, and the inner arc surface of the protective sleeve is provided with a shielding layer and an insulation layer in sequence.

[0007] Preferably, in order to avoid damage during bending, a bending-resistant layer is provided between the protective cover and the shielding layer.

[0008] Preferably, in order to facilitate the positioning and locking of the cable core body and ensure the stability of the core geometry, the locking assembly includes positioning chucks equidistantly arranged inside the protective sleeve, and the positioning chucks have equidistant slots on their circumferential sides, which match the cable core body.

[0009] Preferably, in order to assist in bending and improve flexibility, the bending assistance component includes guide holes equidistantly opened on the positioning chuck, and an elastic body is provided between the guide holes in the same vertical direction.

[0010] Preferably, the positioning chuck has a through hole in the middle.

[0011] Preferably, in order to improve the overall tensile strength, the protective sleeve is filled with a filler layer that matches the main body of the cable core.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The clamping components, in conjunction with the auxiliary bending components, ensure the radial stability of the wire core and the stability of the wire core geometry, without affecting normal use. At the same time, it also avoids excessive filler layers affecting heat dissipation. The auxiliary bending components, together with the filler layer and the bending-resistant layer, do not affect the bending use of the cable body, ensuring safe use.

[0014] The protective sleeve improves wear resistance, oil resistance, and hydrolysis resistance, making it suitable for harsh industrial environments. The shielding layer also provides electromagnetic interference resistance, while the insulation layer offers high elasticity and wear resistance. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a bend-resistant, highly flexible drag chain cable, comprising a protective sheath 11. The protective sheath 11 is mainly composed of a protective sleeve 21, a bend-resistant layer 22, a shielding layer 23, and an insulation layer 24, from the outside in. The protective sleeve 21 can be made of polyurethane or similar materials, exhibiting excellent wear resistance, oil resistance, and hydrolysis resistance, making it suitable for harsh industrial environments. The bend-resistant layer 22 can be made of polytetrafluoroethylene (PTFE) to improve strength without affecting bending performance. The shielding layer 23 can be made of tin-plated copper wire braided shielding (or aluminum foil + copper wire composite shielding), providing both electromagnetic interference resistance and insulation layer 24. 4 can be made of high-density PE or modified PVC, providing high elasticity and wear resistance, supporting the conductor to maintain structural stability during repeated bending. The protective sleeve 11 has cable core bodies 12 arranged at equal intervals inside (the number is set according to the actual situation, which is a relatively mature technology and will not be described in detail here). There is also a filling layer 13 (which can be aramid fiber bundles or tensile ropes) between the protective sleeve 11 and the cable core bodies 12, which is embedded in the center of the cable core or evenly distributed in the circumference to improve the overall tensile strength. The number can be four to six, or other numbers, depending on the application.

[0022] Please see Figures 1-4 To secure and limit the cable core body 12 without affecting normal use, while facilitating bending operations and preventing rotational deviation, the protective sleeve 11 is equipped with equidistant positioning chucks 31 for clamping components. The positioning chucks 31 can be equidistantly spaced, with intervals ranging from 0.5m to 1.0m, such as 0.5, 0.6, 0.7, 0.8, 0.9, 1.0m, or other intervals. The circumferential sides of the positioning chucks 31 are equidistantly provided with slots 34 for engaging with the cable core body 12, facilitating positioning and fixing and preventing deviation. The positioning chucks 31 are also equidistantly provided with guide holes 35 for auxiliary bending components. An elastic body 32 (made of materials such as silicone rubber) for auxiliary bending is inserted between the guide holes 35 in the same vertical direction to facilitate bending. A through hole 33 is provided in the center of the positioning chucks 31.

[0023] Working principle: When in use, the cable core body 12 is clamped and fixed in the slot 34 of the positioning chuck 31, which can assist in positioning and fixing, and avoid displacement. The elastic body 32 in the guide hole 35, together with the filling layer 13, can facilitate the bending of the drag chain cable. At the same time, the bending layer 22 can improve the strength and prevent damage during bending. The protective sleeve 21 can improve wear resistance, oil resistance and hydrolysis resistance, making it suitable for harsh industrial environments. The shielding layer 23 can also resist electromagnetic interference, and the insulation layer 24 can provide high elasticity and wear resistance.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
