Description
Technical Field
[0001] The utility model relates to the technical field of wire and cable, in particular to a stranded wire structure. Background Art
[0002] With the rapid development of modern electronic technology, the demands for data transmission and power transmission are increasing day by day. As a common transmission line, the stranded wire is widely used in various electronic devices and systems. The stranded wire structure is formed by stranding multiple wire bodies. Compared with a single wire body, its structure is more stable and can reduce electromagnetic interference. The traditional stranded wire structure usually includes an outer sheath and internal core conductors. However, in complex and changeable application environments, its transmission stability and durability often fail to meet high-level requirements. Especially in terms of resisting external interference, protecting the internal core conductors from damage, and ensuring long-term reliable transmission, the traditional stranded wire structure exposes obvious deficiencies.
[0003] In the existing technical means, in order to improve the anti-interference ability and structural strength of the stranded wire, structures such as a shielding layer and reinforcing ribs are usually added. However, these means often lead to a decrease in the flexibility and portability of the wire, and at the same time increase the production cost. Summary of the Utility Model

[0013] By adopting the above technical solution, the wire is made of bare copper material and is a single wire, which can form a good conductive connection with the braided layer, thereby maintaining the stability of the internal transmission environment of the stranded wire.
[0014] Preferably, the aluminum foil layer is completely closed, and the aluminum foil layer is used to provide an additional shielding effect.
[0015] By adopting the above technical solution, the aluminum foil layer adopts a completely closed design, providing a tight shielding barrier, effectively isolating external electromagnetic interference, and ensuring the accuracy of data transmission.
[0016] Preferably, a filler is arranged between the aluminum foil and the twisted pair, which is used to keep the position of the twisted pair stable and absorb external impact force.
[0017] By adopting the above technical solution, the arranged filler facilitates improving the stability of the twisted pair inside the aluminum foil, ensuring that no unstable situation will occur during use.

It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.
[0030] The present utility model discloses a stranded wire structure, as Figure 1 , Figure 2 shown, which includes an outer sheath 1. A waterproof coating 11 is provided on the outer surface of the outer sheath 1. The waterproof coating 11 is used to provide a waterproof function. This layer of waterproof coating 11 is designed to endow the cable with a waterproof function and enhance its reliability in humid or rainy environments. The outer sheath 1 is arranged on the outermost side of the stranded wire structure. A braided layer 2 is arranged inside the outer sheath 1. The braided layer 2 is woven from metal wires 8. This braided layer 2 not only enhances the tensile strength of the entire cable structure but also greatly improves its shielding effectiveness, enabling the cable to effectively resist external electromagnetic interference during signal transmission. At the same time, the braided layer 2 can also adopt a more complex braiding method, such as double-layer or multi-layer braiding, to increase the density and tensile strength of the braided layer 2. An aluminum foil 3 is arranged inside the braided layer 2. The aluminum foil 3 is annular and closely adheres to the inside of the braided layer 2. A groove 9 is arranged between the outer side of the aluminum foil 3 and the braided layer 2. A ground wire 4 is arranged between the braided layer 2 and the aluminum foil 3. The ground wire 4 is arranged in the groove 9. The ground wire 4 is properly arranged in the groove 9, so as to ensure that static electricity or lightning current can be safely and quickly guided to the ground, greatly improving the use safety. The ground wire 4 is made of bare copper material and is a single wire. A plurality of twisted pairs 5 are arranged inside the aluminum foil 3. The twisted pairs 5 are formed by twisting a plurality of core wire conductors 6 with a certain pitch. Such a design not only improves the flexibility of the cable but also helps to reduce interference during signal transmission. A filler 10 is arranged between the aluminum foil 3 and the twisted pairs 5. The filler 10 adopts a filling material with higher elasticity and buffering performance, such as a polymer elastomer or silica gel. The purpose of this is to keep the position of the twisted pairs 5 stable and be able to absorb the impact from the outside, providing additional protection for the internal core wires. The core wire conductors 6 are made of tinned copper material and are used to transmit electrical signals. A layer of insulating protective layer 7 is closely wrapped around the periphery of each core wire conductor 6. The function of this layer is to prevent current leakage and ensure the stability of signal transmission and the safety of cable use.
[0031] Working principle: A stranded wire structure designed by the present utility model mainly enhances the tensile strength and shielding effectiveness of the cable through the braided layer 2, ensuring that the cable can still operate stably when subjected to external pulling force or electromagnetic interference. The design of the ground wire 4 can timely conduct static electricity or lightning current into the ground to prevent the current from damaging the electronic components inside the cable. By setting the core wire conductor 6 made of tinned copper material, the stable transmission of signals is ensured, and an insulating protective layer 7 is arranged outside the core wire conductor 6 to effectively prevent current leakage and avoid safety problems such as electrical short circuits. The filler 10 is set to help fix the position of the twisted pair 5, buffer the external impact force, and protect the internal core wire. Therefore, the stranded wire structure designed by the present utility model is convenient for improving the anti-interference ability of the stranded wire and the stability of the stranded wire structure.
[0032] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
