[0028] Please see Figure 1 The connecting wire 100 consists of a wire core 110, an insulating protective sleeve 120, and a connector 130.

[0029] In one specific embodiment, the core 110 consists of two mutually insulated first and second conductive wires. These two conductive wires are isolated by a high-performance insulating material (such as high-density polyethylene or cross-linked polyvinyl chloride) to ensure that current or signals are transmitted independently in their respective lines without interference. The core 110 is made of tin-plated copper with a stranded structure. This material not only has excellent conductivity but also good corrosion resistance and mechanical strength, and can withstand large tensile and bending forces. The stranded structure of the core 110 includes at least these two mutually insulated conductive wires. Through a precise stranding process, the overall flexibility and durability are enhanced, so that the connecting wire can maintain good transmission performance even in complex environments.

[0030] In one specific embodiment, the insulating sleeve 120 tightly wraps around the wire core 110, providing electrical insulation and mechanical protection. The sleeve is designed as a hollow cylindrical structure to accommodate the wire core 110. The insulating sleeve 120 is typically made of a material with excellent electrical insulation properties and mechanical strength, such as flame-retardant polyvinyl chloride (PVC) or thermoplastic elastomer (TPE). These materials not only have excellent insulation properties but also maintain stable performance in high temperature, low temperature, or humid environments. In addition, the outer surface of the insulating sleeve 120 may be provided with anti-slip textures or abrasion-resistant layers to improve the durability and safety of the connecting wire.

[0031] In one specific embodiment, connector 130 is the part that connects the connecting wire 100 to an external device. It mainly consists of a connector 131 and a flexible sleeve 132. The connector 131 is located at one end of the flexible sleeve 132 and is used for reliable connection with external devices (such as electronic devices, sockets, etc.). The connector 131 has metal contacts inside for interfacing with the interface of the external device to realize the transmission of current or signals. The flexible sleeve 132 is also a hollow structure, which can accommodate the wire core 110 and its external insulating protective sleeve 120. In particular, the wall thickness of the flexible sleeve 132 near the connector 131 is designed to be greater than the wall thickness of the end away from the connector 131. This design enhances the strength and durability of the connection area and helps resist the stress that may be generated during insertion and removal. At the same time, the choice of material for the flexible sleeve 132 is also crucial. It is usually made of soft and wear-resistant rubber or silicone material to ensure smooth insertion and removal and to prevent damage.

[0032] Please see Figure 2 and Figure 3 In one specific embodiment, the outer wall of sleeve 132 is slightly inclined relative to the axis of its hollow structure. This design is not only aesthetically pleasing, but more importantly, combined with the increased wall thickness near the connector 131 end, it further optimizes the stress distribution in the connection area and improves the overall fatigue resistance. The inclined outer wall also acts as a guide during insertion and removal, making it easier for the connecting wire to enter or leave the interface of the external device.

[0033] In one specific embodiment, the inner wall of the sleeve 132 is inclined relative to the axis of its hollow structure. This design aims to enhance the stability and durability of the connector 131 by adjusting the wall thickness distribution, while maintaining good insertion and removal smoothness. The inclined inner wall can also reduce the friction of the wire core 110 inside the sleeve 132, extending the service life of the connector.

[0034] In one specific embodiment, the hollow structure of the soft sleeve 132 is designed in a stepped shape, with a smaller inner diameter and a larger wall thickness at the end closer to the connector 131, while the inner diameter gradually increases and the wall thickness decreases accordingly at the end farther away from the connector 131. This stepped design not only facilitates the smooth insertion of the wire core 110, but also effectively improves the strength and stability of the connection area. At the same time, the stepped structure can also provide additional support for the wire core 110, reducing its shaking during insertion and removal.

[0035] In one specific embodiment, the connector 131 is inclined relative to the axial structure of the soft sleeve 132, with the inclination angle controlled between 30° and 60°. This inclination design helps to more easily achieve connection with external devices in a limited space, while reducing the resistance during insertion and removal and improving the user experience. In addition, the inclination connector 131 can also increase the contact area with the interface of the external device to a certain extent, thereby improving the stability of the connection.

[0036] In one specific embodiment, the connecting surface of the connector 131 is a rectangular structure. This design facilitates a stable connection with an external device that has a corresponding interface, reducing the risk of accidental detachment. Of course, depending on actual needs, the connecting surface can also adopt a circular structure, a triangular structure, or other shapes. The surface of the connector 131 can also be treated with gold plating, tin plating, nickel plating, etc., to improve its conductivity and corrosion resistance.

[0037] In one specific embodiment, in order to simplify the manufacturing process and improve the integrity of the components, the soft sleeve 132 and the connector 131 in this embodiment are designed as an integral plastic part structure. Through processes such as injection molding, seamless connection between components is ensured, improving the overall strength and durability. At the same time, the integral plastic part structure can also reduce errors and loosening problems during the assembly process, and improve the reliability and stability of the connection line.

[0038] Please see Figure 4 This cable can be widely used in various electronic device connections, communication device connections, automotive electronic connections, and other fields. Furthermore, due to its excellent protective performance and durability, it can also be used in industrial control, medical equipment, aerospace, and other fields requiring high reliability and stability.

[0039] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
