Description

Technical Field

[0001] This utility model relates to a cable structure. Background Technology

[0002] Mobile device reel cables are special cables designed specifically for powering, controlling, or transmitting data to mobile devices that require frequent cable winding and unwinding. They are a type of cable installed on a cable reel. Their core function is to continuously and stably transmit electrical energy or signals as the device moves (e.g., forward, backward, lifting, rotating) and unwinds (winds up). They must withstand mechanical stresses that ordinary cables cannot withstand.

[0003] Compared to conventional fixed-installation cables, mobile reel cables must meet extremely stringent requirements, capable of withstanding repeated bending and winding without damage. During the cable winding and unwinding process, the cable not only bends but may also experience torsional forces. The outer sheath material must be exceptionally tough, resisting friction with the ground, the reel surface, and other cables.

[0004] Existing technology CN204315253U discloses a reinforced tensile-resistant mobile flat flexible cable, which consists of adding a tensile-resistant steel wire rope on both sides to improve tensile strength. The drawback of this cable structure is the lack of a signal conductor and a shielding layer, resulting in weak resistance to electromagnetic interference. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a tensile-resistant, wear-resistant, and anti-winding reel cable, which incorporates a signal fiber core and a shielding layer, integrating signal transmission functionality while maintaining tensile strength.

[0006] This utility model is achieved through the following technical solution: A tensile, abrasion-resistant, and anti-winding drum cable for mobile equipment includes a flat outer sheath 1 and an inner insulated core 2. In cross-section, tensile steel wire 10, four insulated cores 2, signal core 3, and tensile steel wire 10 are arranged sequentially from left to right in the outer sheath 1. The four insulated cores 2 and the signal core 3 are bent to a certain extent in the longitudinal direction, while the two tensile steel wires 10 are straightened in the longitudinal direction.

[0007] Furthermore, the insulated wire core 2 is covered with a cross-linked polyethylene insulation layer 21, and the cross-linked polyethylene insulation layer 21 is covered with a copper tape shielding layer 20.

[0008] Furthermore, the signal wire core 3 is composed of multiple signal wires twisted together, the signal wire core 3 is covered with a flame-retardant tape 31, the flame-retardant tape 31 is covered with a polyethylene sheath 32, and the polyethylene sheath 32 is covered with a copper strip shielding layer 20.

[0009] Furthermore, the tensile steel wire 10 is covered with a sheath 11.

[0010] Furthermore, the outer wall surfaces of the adjacent copper strip shielding layers 20 are in contact with each other.

[0011] Furthermore, the gaps between the signal lines of the signal line core 3 are filled with glass fiber 30.

[0012] Furthermore, the outer sheath 1 is made of polyurethane material.

[0013] The beneficial effects of this utility model are as follows: 1. The insulated core and signal core adopt a bending design. When the cable is subjected to tension, the insulated core and signal core will only use bending deformation to offset the tensile deformation, and the steel wire will bear all the tensile stress.

[0014] 2. Signal lines can handle signal and data transmission, so there is no need to design additional signal lines when laying cables.

[0015] 3. The wire cores are all shielded with copper tape to prevent electromagnetic interference. The copper tape shielding on the outside of the signal line can prevent signal transmission from being affected. The copper tapes are in contact with each other to form an integral shielding structure, forming a closed electromagnetic channel to prevent signal leakage and reflection.

[0016] 4. The tensile steel wire is extruded with a polyethylene sheath, which can separate the tensile steel wire from the copper strip to prevent electrochemical corrosion caused by contact between the steel wire and the copper strip during the production process, thus enhancing the service life.

[0022] Example 1: As Figure 1 This is a schematic diagram of the cable's cross-section. The outer sheath 1 has a racetrack-shaped outer contour, with a tensile steel wire 10 at each end. Between the two tensile steel wires 10, there are four insulated cores 2 and one signal core 3. The four insulated cores 2 and the signal core 3 are bent in the longitudinal direction, while the two tensile steel wires 10 are straight in the longitudinal direction. That is, all cores are designed to be bent, while the steel wires are designed to be straight. When the cable is bent or subjected to tension, the steel wires bear all the load.

[0023] Each insulated core 2 consists of a central conductor covered with a cross-linked polyethylene insulation layer 21, and the cross-linked polyethylene insulation layer 21 is covered with a copper tape shielding layer 20.

The signal wire core 3 is covered with a flame-retardant tape 31, the flame-retardant tape 31 is covered with a polyethylene sheath 32, and the polyethylene sheath 32 is covered with a copper tape shielding layer 20. The gaps between the signal wires of the signal wire core 3 are filled with glass fiber 30 to improve the strength of the fiber core.

[0025] The five adjacent copper strip shielding layers 20 are in contact with each other to form a whole shielding layer.

[0026] The tensile steel wire 10 is covered with a sheath 11 made of polyethylene, which prevents electrochemical corrosion from occurring when the steel wire comes into contact with the copper strip during production. The tensile steel wire 10 is made of multiple thin steel wires twisted together.

[0027] The outer sheath 1 is made of polyurethane, an extremely wear-resistant material. The urethane bonds in the polyurethane molecule provide extremely high mechanical strength and toughness, enabling it to effectively resist wear, tear and impact.
