Description

Technical Field

[0001] The utility model belongs to the technical field of data cables, and in particular relates to a full-magnetic charging data cable. Background Art

[0002] Data cables are used to connect computers and mobile devices such as mobile phones, so that data can be transferred or communicated between them. They can also be connected to chargers to charge mobile devices. Data cables can transmit data because their inner core is made of conductive materials, usually copper or aluminum wires. When both ends of the data cable are connected to the device or interface, the data signal is transmitted in the wire through the current. Data cables are widely used, mainly including 3C digital products such as mobile phones, computers, and tablets. The structure of mobile phone charging data cables is relatively simple, and the basic structure is that both ends of the cable are fixedly connected to the connector.

[0003] Since battery technology has not made further breakthroughs in capacity, the battery life of mobile phones often cannot meet people's needs. Therefore, people need to carry data cables at all times. However, data cables are relatively long and not easy to coil. Due to the flexible nature of data cables, data cables appear messy when stored, especially in application scenarios where data cables need to be stored in narrow spaces such as handbags, pockets, and backpacks. Messy data cables not only occupy a larger storage space, but also seriously affect users' access to other items in the same space. They are inconvenient to use and visually very messy. Especially if there are multiple data cables at the same time, they will be entangled, making storage inconvenient and making people uncomfortable. In addition, due to external tension, their own gravity or repeated folding and winding, problems such as short service life and easy twisting and breaking of the cable are caused. In order to solve the above problems, there are currently two main design solutions. One is to add an automatically retractable mechanical structure to the data cable, such as the "single-pull retractable data cable" provided by Chinese utility model patent CN218242480U; the other is to change part of the material of the data cable, such as the Chinese utility model patent CN211981061U provides a "magnetic data cable" that achieves the purpose of magnetically organizing and storing the data cable by replacing part of the outer layer of the data cable or adding magnetic parts.

[0004] However, although adding a mechanical structure to the data cable can solve the problems of automatic shrinkage and messy lines of the data cable, the mechanical structure for winding the data cable will always be hung on the data cable, increasing the storage space and making it more inconvenient to use than before. By replacing the outer layer or adding magnetic suction parts, personnel are required to fold them in an orderly manner to correspond to the magnets so that they can attract each other and achieve the purpose of winding the cable. It cannot shrink automatically. If it is not folded, the magnets will not attract each other, and the data cable will still be messy and entangled. Therefore, a fully magnetic charging data cable is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a fully magnetic charging data cable, aiming to solve the problems that the existing mobile phone charging data cable in the background technology is difficult to coil, appears messy when stored, has a short service life and is easy to twist and break due to external tension, its own gravity or repeated winding and entanglement.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is: a fully magnetic charging data cable, including a wire body and an input connector and an output connector distributed at both ends of the data cable body. The wire body includes, from the inside to the outside, a copper core wire layer wrapped with insulating material, a shielding layer wrapped with insulating material and provided with a wear-resistant coating on the surface, a fully magnetic layer and an external protective layer. The copper core wire layer is dispersed in the fully magnetic layer, and at least includes a charging line, a data transmission line, and a ground line. The fully magnetic layer is a flexible polymer composite material with permanent magnetic magnetic powder, adhesive and auxiliary agent as filler. The material of the external protective layer is high-performance fiber. This technical solution uses copper core wires dispersed in the fully magnetic layer to reduce the overall stiffness of the data cable, and automatically adsorbs through the magnetic attraction of the two poles of the fully magnetic layer, so that the charging data cable is in a curled coil or a curled reincarnation stacked disc shape in normal state. Among them, when it is in a curled coil shape, any adjacent data lines in the vertical direction have the north and south magnetic poles attracting each other, and the magnetic attraction is spread all over the end faces of the entire data line in the vertical direction; when it is in a curled and stacked disk shape, any adjacent data lines in the radial direction have the north and south magnetic poles attracting each other, achieving normal magnetic attraction.

[0007] To further describe the above solution, the magnetic powder is samarium iron nitrogen magnetic powder or neodymium iron nitrogen magnetic powder.

[0008] Optionally, the insulating material is flexible silicone and the shielding layer is aluminum foil.

[0009] Furthermore, the high performance fiber is cross-woven by ultra-high molecular weight polyethylene fibers or cross-woven by nylon fibers.

[0010] Furthermore, the input connector and the output connector are both one of a USB connector, a Mini-USB connector, a Micro-USB connector, a TYPE-C connector or a Lightning connector, and the input connector is different from the output connector.

[0011] Furthermore, the main body of the flexible polymer composite material is a thermoplastic elastomer (TPE) or thermoplastic polyurethane elastomer rubber (TPU) material.

[0012] More preferably, the cross-section of the wire body includes a circle, an ellipse, a rounded rectangle or any irregular shape.

[0013] Compared with the prior art, the utility model adopts copper core wires dispersedly distributed in the full magnetic absorption layer to reduce the overall stiffness of the data line, and automatically adsorbs through the magnetic attraction of the two poles of the full magnetic absorption layer, so that the charging data line is in a curled coil shape or a curled and stacked coil shape in a normal state. At the same time, the material of the external protective layer is high-performance fiber to ensure that the line body is twisted and broken in different ways. It can effectively solve the problems of the existing mobile phone charging data cable being difficult to coil, appearing messy in the storage state, and having a short service life and the line body being easy to twist and break due to external tension, its own gravity or repeated winding and entanglement.

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] See also Figure 3 , Figure 4The utility model provides a full magnetic charging data cable, including a wire body 1 and an input connector 2 and an output connector 3 distributed at both ends of the data wire body 1. The wire body 1 includes a copper core wire layer 10 wrapped with an insulating material 11, a shielding layer 12 wrapped with the insulating material 11 and provided with a wear-resistant coating on the surface, a full magnetic layer 13 and an external protective layer 14 from the inside to the outside, wherein the copper core is used to transmit data signals and currents, the insulating material 11 is used to protect the copper core, the shielding layer 12 is used to prevent the internal copper core from being affected by the external electromagnetic field or interference signal and to prevent the interference electromagnetic field of the copper core from spreading outward, the wear-resistant coating is used to reduce the friction between the shielding layer 12 and the full magnetic layer, and prolong the service life, the full magnetic layer 13 is used for the wire body 1 to automatically curl and coil, and the external protective layer 14 is the entire wire body 1. The copper core wire layer 10 is dispersed in the full magnetic layer 13, including at least a charging wire, a data transmission wire, and a ground wire. The full magnetic layer 13 is a flexible polymer composite material with permanent magnetic filler magnetic powder, adhesive and additives. The material of the outer protective layer 14 is high-performance fiber. This technical solution uses copper core wires dispersed in the full magnetic absorption layer 13 to reduce the overall stiffness of the data line, and automatically adsorbs through the magnetic attraction of the two poles of the full magnetic absorption layer 13, so that the charging data line is in a curled coil or a curled reincarnation stacked disc shape in normal state. Among them, when in a curled coil shape, any adjacent data lines in the vertical direction belong to the mutual attraction of the north and south magnetic poles, and the magnetic attraction covers the end face of the entire data line in the vertical direction; when in a curled reincarnation stacked disc shape, any adjacent data lines in the radial direction belong to the mutual attraction of the north and south magnetic poles, realizing normal magnetic attraction.

[0023] The magnetic powder is samarium iron nitrogen magnetic powder or neodymium iron nitrogen magnetic powder. The samarium iron nitrogen magnetic powder and neodymium iron nitrogen magnetic powder have high magnetic properties, uniform magnetism, and small average particle size. They can be made into strips, sheets, and rings. They have good flexibility and tensile properties. They can be well combined with thermoplastic elastomers (TPE), thermoplastic polyurethane elastomer rubber (TPU) and other elastomeric materials and then magnetized to provide magnetic attraction. The insulating material 11 is flexible silicone. When the charging cable is stretched and extended, the silicone insulation layer will also follow the stretching and extension of the device, which can achieve the effect of extending the buffer. At the same time, silicone has good elasticity and flexibility and is easy to deform. The shielding layer 12 is aluminum foil. The high-performance fiber is made of ultra-high molecular weight polyethylene fiber cross-woven or nylon fiber cross-woven, which is wear-resistant and bending-resistant, has good tension fatigue resistance, and can increase the service life of the braided data cable. The input connector 2 and the output connector 3 are both one of a USB connector, a Mini-USB connector, a Micro-USB connector, a TYPE-C connector or a Lightning connector, and the input connector 2 is different from the output connector 3, so that the input connector 2 and the output connector 3 do not have the same connector. The main body of the flexible polymer composite material is a thermoplastic elastomer (TPE) or a thermoplastic polyurethane elastomer rubber (TPU) material. The cross-section of the wire body 1 includes a circle, an ellipse, a rounded rectangle or any irregular shape, and the design can be adjusted to meet different needs.

[0024] In actual use, the fully magnetic charging data cable provided by the utility model is in a curled strip or a curled reincarnation stacked disc in a normal state. The principle of maintaining these two states is that the entire line body 1 uses flexible silicone and flexible high-performance fibers, wherein the flexible high-performance fibers use elastomeric materials, which are easy to bend and recover, and the line body 1 of the copper core layer is dispersed and distributed to reduce the combined force, making it easier to bend, and with the magnetic powder modified, fully magnetically covered flexible polymer composite material, when curled strip, any adjacent data lines in the vertical direction belong to the mutual attraction of the north and south magnetic poles, and the magnetic adsorption is full of the end surface of the entire data line in the vertical direction; when curled reincarnation stacked disc, any adjacent data lines in the radial direction belong to the mutual attraction of the north and south magnetic poles, realizing normal magnetic adsorption. When using it to charge a mobile phone, one end of the stretch input connector 2 is connected to the power supply, and the other end of the stretch output connector 3 is connected to the mobile phone. At this time, the data line of the bending and stretching section still maintains the curled disc state. After use, just loosen the connector, and the line body 1 shrinks under the magnetic attraction of the north and south magnetic poles and returns to the curled disc state.

[0025] To sum up, the utility model adopts copper core wires dispersedly distributed in the full magnetic absorption layer to reduce the overall stiffness of the data line, and automatically adsorbs through the magnetic attraction of the two poles of the full magnetic absorption layer, so that the charging data line is in a curled coil or a curled and stacked coil in the normal state. When in use, it is only necessary to stretch the input connector and the output connector at both ends of the data line, and loosen the input connector and the output connector. The data line automatically returns to the curled coil state under the action of magnetic attraction. It can effectively solve the problems that the existing mobile phone charging data line is not easy to coil, appears messy in the storage state, and has a short service life and the line body is easy to twist and break due to external tension, its own gravity or repeated folding and winding.
