Description

Technical Field

[0001] This utility model belongs to the field of towing cable technology, and in particular relates to a mobile towing cable. Background Technology

[0002] Mobile towing cables, also known as towing system cables or reel / towing cables, are cables specifically designed for repeated bending and dragging in mobile power supply and signal transmission systems (such as towing systems and reel systems).

[0003] Currently, bending deformation of towing cables is accompanied by torsional deformation, resulting in radial deformation of the cable. The internal structure (especially the shielding structure) is prone to mutual compression, and the deformation cannot be recovered.

[0004] To address the aforementioned problems, this application proposes a mobile towing cable. Utility Model Content

[0005] The purpose of this invention is to provide a mobile towing cable that solves the problems in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a mobile towing cable, including a conductor core, a support column, and a sheathing layer;

[0008] The outer side of the guide core is provided with an anti-torsion layer, and the inner side of the anti-torsion layer has multiple reinforcing ribs evenly distributed in the circumferential direction, which serve as an elastic support.

[0009] The anti-torsion layer is provided with a shielding layer on its outer side, the shielding layer including an inner shielding section and an outer shielding section;

[0010] Both the inner and outer shielding sections are annular structures arranged at equal intervals along the axis.

[0011] Preferably, a spirally wound wrapping layer is provided between the guide core and the anti-torsion layer, which serves as an elastically deformable support.

[0012] Preferably, the shielding layer has an inner connecting layer and an outer connecting layer on its inner and outer sides, respectively. The inner connecting layer is connected to the anti-torsion layer, and the outer connecting layer is connected to the covering layer.

[0013] Preferably, the inner shield and the outer shield are connected to form a rear annular cavity.

[0014] Preferably, the outer shielding section is located outside the annular cavity between adjacent inner shielding sections.

[0015] Preferably, a shielding connector is provided between the axially adjacent annular bodies of the inner and outer shielding sections.

[0016] Preferably, the inner shielding section and the outer shielding section are in rolling contact.

[0017] This utility model has the following beneficial effects:

[0018] 1. By setting an anti-torsion layer inside the cable, the reinforcing ribs resist torsional deformation and provide a restoring force after the cable is torn. This can prevent the cable from being too twisted and allow it to recover quickly, thus maintaining the structural stability of the cable under frequent multi-directional deformation.

[0019] 2. By arranging the shielding layers at intervals and connecting them with shielding connectors, as well as the staggered distribution of the inner and outer layers, the cable achieves the effect of corresponding deflection under torsional deformation, thereby avoiding irreversible damage caused by hard pulling, while maintaining good shielding performance in the deflection state.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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.

[0029] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] A mobile towing cable is designed to maintain structural stability under frequent torsional deformation. It is achieved by arranging the shielding layer 17 in axially equally spaced segments and connecting them in series via shielding connectors 1701. The staggered structure of the inner and outer double layers enables the shielding structure to be torn within a certain range without affecting the shielding performance. At the same time, the reinforcing ribs 141 resist the torsional force and promptly drive the cable to recover when the torsional force disappears, thereby ensuring the structural stability of the cable under torsional deformation.

[0031] In some embodiments, the specific structure of the mobile towing cable is as follows: Figures 1 to 3 As shown, it includes a conductor core 11 and an outer covering layer 13, and between the two, from the inside to the outside, there are an anti-torsion layer 14, an inner connecting layer 15, a shielding layer 17 and an outer connecting layer 16.

[0032] It should be noted that the center of the cable is a support post 12, which is made of glass fiber reinforced plastic, and multiple strands of annealed soft copper wire are twisted together on the outside to form a conductor core 11;

[0033] The coating layer 13 is extruded from polyurethane or neoprene rubber.

[0034] like Figure 1 As shown, a wrapping layer 111 is spirally wound on the outer side of the guide core 11. This wrapping layer is an elastic support body that is compressed and retracted when the guide core 11 is bent or twisted, so as to provide deformation space for the wrapping layer 111.

[0035] It should be noted that the wrapping layer 111 is made of polyester film or non-woven fabric tape.

[0036] like Figure 1 As shown, the anti-torsion layer 14 has axially extending reinforcing ribs 141 embedded inside, which are evenly distributed circumferentially.

[0037] Understandably, the reinforcing rib 141, through its own elasticity, can both resist torsional deformation and promote the torsional recovery of the cable.

[0038] In addition, the reinforcing rib 141 can also withstand the main pulling force of the cable, preventing other structures from being pulled and deformed.

[0039] It should be noted that the anti-torsion layer 14 is supported by thermoplastic elastomer extrusion, and the reinforcing ribs are pre-laid longitudinally on the outside of the wrapping layer 111 during extrusion.

[0040] Reinforcing rib 141 is made of aramid fiber or high-elasticity steel wire.

[0041] like Figure 2 As shown, the shielding layer 17 has a double-layer structure, with the inner and outer layers connected and fixed to adjacent components through the inner connecting layer 15 and the outer connecting layer 16, respectively.

[0042] The shielding layer 17 includes an inner shielding section 171 and an outer shielding section 172, both of which are short-pitch annular structures, axially evenly distributed, and a shielding connector 1701 is connected in series between adjacent bodies to maintain the linkage of the shielding structure.

[0043] It is understood that a gap is formed between the axially adjacent bodies of the inner shielding section 171 and the outer shielding section 172, which can be twisted accordingly under torsional deformation and maintained by the shielding connector 1701;

[0044] In addition, the inner shielding section 171 and the outer shielding section 172 are in rolling contact, and their opposite sides are connected and fixed to the adjacent components, which achieves the effect of reducing the deflection amplitude of the internal structure due to the traction deflection of the cable inside and outside.

[0045] It should be noted that both the inner connecting layer 15 and the outer connecting layer 16 are bonded using elastic adhesive or textile strapping.

[0046] The inner shielding layer 171 and the outer shielding strip 172 are woven from short-pitch copper strips or tin-plated copper wires.

[0047] The shielding connector 1701 is made of flexible metal spring sheet or conductive braided strip and connects adjacent shielding sections.
