[0002] With the rapid development of electronic technology, power signal braided cables are an important medium for signal transmission between electronic devices. Their performance and stability are directly related to the operation effect of the entire system. Traditional power signal braided cables are mostly composed of a single or multiple battery cells. There is a lack of effective isolation and protection measures between the battery cells. They are prone to short circuits or reduced insulation performance when bent, stretched or when the external environment changes, thus affecting the accuracy and stability of signal transmission.

[0003] In addition, the traditional power signal braided cable is usually only covered with an insulating layer outside the battery cell. This design is incapable of coping with complex and changing external environments. Especially under extreme conditions such as high temperature, high humidity, and high voltage, the insulating layer is prone to aging and cracking, resulting in the battery cell being exposed, which in turn causes safety accidents.

[0004] Therefore, developing a power signal braided cable with excellent insulation performance and good isolation effect between battery cells has become an urgent problem to be solved in the current electronic technology field. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0024] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0025] In an embodiment of the utility model, this case provides a power signal braided cable, including four conductive cells 100 arranged in a rectangular shape, the conductive cell 100 including a copper core 101 and a steel core 102, a plurality of steel cores 102 are wound around the copper core 101, and the steel cores 102 are distributed in concentric circles on the outside of the conductive cell 100; the outer surface of the conductive cell 100 is covered by an insulating layer 110; a filling layer 120 is further provided between the insulating layer 110 and the conductive cell 100, and four groups of soft glue protective layers 130 are provided in the filling layer 120, and the four groups of soft glue protective layers 130 are distributed symmetrically at 90°, one end of which is connected to the inner wall of the insulating layer 110, and the other end points to the central end of the conductive cell 100 to separate the conductive cells 100.

[0026] Specifically, by distributing the steel core 102 in concentric circles around the copper core 101, not only the overall strength and stability of the conductive core 100 are significantly improved, but also the conductive performance is effectively improved. The conductive core 100 of this composite structure can not only resist the impact and vibration of the external environment, but also maintain stable current transmission under high load, greatly extending the service life of the braided wire. By arranging a filling layer 120 between the conductive cores 100, and arranging four groups of soft glue protective layers 130 symmetrically distributed at 90° in the filling layer 120, the present invention effectively separates the conductive cores 100, prevents direct contact between the cores, and thus avoids the occurrence of short circuits. The outer surface of the conductive core 100 is covered by the insulating layer 110, forming a complete insulating barrier, which effectively prevents the leakage of current and the erosion of the core by the external environment. At the same time, the soft glue protective layer 130 also enhances the stability of the insulating layer 110, further improving the insulation performance. The soft rubber protective layer 130 has certain elasticity and flexibility, and can maintain the stability of the structure when the power signal braided line is bent and stretched, thereby reducing the risk of damage to the insulating layer 110 and exposure of the battery cell due to deformation.

[0027] In another embodiment, the diameter of the single wire of the copper core 101 is 0.500-0.600 mm. The diameter of the single wire of the steel core 102 is 0.140-0.150 mm. The diameter of the single wire of the copper core 101 is in the range of 0.500-0.600 mm. This diameter design can ensure that the wire has sufficient conductivity. As an excellent conductive material, the diameter of copper directly affects the resistance and current transmission capacity of the wire. The addition of the steel core 102 enhances the mechanical strength of the wire. The diameter of the single wire of the steel core 102 is in the range of 0.140-0.150 mm, which can ensure the structural strength of the wire without excessively increasing the overall diameter and weight of the wire. Such a design makes the wire more durable when subjected to external forces such as tension and pressure, reducing the risk of breakage.

[0028] In another embodiment, the four groups of soft glue protective layers 130 are separated from each other, and the soft glue protective layers 130 are composed of aerogel. Specifically, one end of the four groups of soft glue protective layers 130 is not connected to the same center of the circle, but is separated, which further enhances the insulation effect. The separated soft glue protective layers 130 can be more accurately positioned between the conductive battery cells 100100 to ensure the isolation effect between the battery cells. The elasticity and flexibility of aerogel enable it to fit tightly to the surface of the braided wire to form an effective protective layer. This close fit not only enhances the overall strength of the braided wire, but also improves its tensile and bending resistance, avoiding damage to the conductive layer during contraction or bending. This design avoids the problem of poor isolation effect that may be caused by overlapping or interlacing between protective layers.

[0029] In another embodiment, the insulating layer 110 is made of fluoroplastics. Fluoroplastics have extremely high insulation resistance and withstand voltage strength, which makes it an ideal insulating material. Using fluoroplastics as the insulating layer 110 can effectively prevent the leakage of current and the occurrence of leakage, and ensure the stability and safety of the power signal braided cable when transmitting signals.

[0030] In another embodiment, the outer surface of a single conductive battery cell 100 is covered with an elastic layer 140, and the elastic layer 140 is made of elastic fiber material. By covering the elastic layer 140 made of elastic fiber material, the flexibility of the single conductive battery cell 100 is significantly improved. This means that when the power signal braided wire is bent, twisted or stretched, the battery cell can better adapt to the deformation, reducing the risk of damage or breakage of the battery cell due to external force. At the same time, the elastic layer 140 can also absorb and disperse external impact force to a certain extent, thereby improving the folding resistance of the battery cell.

[0031] In another embodiment, the outside of the insulating layer 110 is further covered with a woven fabric layer 150, and the woven fabric layer 150 is a fiber filament, and the raw material of the fiber filament is Kevlar fiber. Kevlar fiber is known for its excellent strength and wear resistance. The woven fabric layer 150 using Kevlar fiber as the raw material of the fiber filament can greatly improve the wear resistance and tear resistance of the power signal braided wire. This means that when the braided wire is subjected to external friction, pulling or impact, it can maintain better integrity, reduce the risk of damage, and thus extend its service life.

[0032] In another embodiment, a protective cover 160 is provided on the outside of the woven layer 150, and the protective cover 160 is a conductive silicone layer. Hooking portions 170 extending outward are arranged in sequence on the protective cover 160, and the hooking portions 170 extend outward and then bend downward for attachment and installation. The protective cover 160 with a conductive silicone layer is added to the outside of the woven layer 150. The conductive silicone layer not only has good insulation properties, which can prevent current leakage and electromagnetic interference, but also can resist the intrusion of pollutants such as moisture and dust in the external environment, providing an additional protective layer for the braided wire. The hooking portion 170 on the protective cover 160 is cleverly designed. It extends outward and then bends downward. At this time, the bending angle is greater than 90°, forming a limiting structure, so that the braided wire can be conveniently attached to various installation positions.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
