[0001] The utility model relates to the technical field of connecting wires, in particular to a connecting wire with a tensile structure. Background Technique
[0002] A connecting wire is an important component used to conduct current, transmit signals or achieve electrical connection in electronic and electrical systems. It usually consists of a conductor, an insulating layer, a sheath, etc. The conductor generally uses metal materials with good electrical conductivity such as copper and aluminum, and its shape and specifications are diverse to adapt to different current and signal transmission requirements. The insulating layer is used to isolate the conductor from the outside world to prevent current leakage and short circuit, and common materials include plastics, rubbers, etc. The sheath provides additional protection to enhance the wear resistance, corrosion resistance and tensile resistance of the connecting wire. Connecting wires play a key role in various fields such as electronic devices, power systems, communication networks, etc., ensuring the accurate and stable transmission of energy and information.
[0003] In various usage scenarios of connecting wires, due to frequent physical movement, dragging between devices or accidental stretching, they will encounter continuous tensile forces. However, existing connecting wires generally do not have a tensile structure. When the tensile force exceeds the bearing limit of the connecting wire, serious problems such as wire breakage or insulating layer damage will occur. Content of the Utility Model
[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, during the use of the connecting wire, due to various factors, the connecting wire will encounter continuous tensile forces, and the connecting wire does not have a tensile structure, resulting in wire breakage or insulating layer damage, and thus a connecting wire with a tensile structure is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A connecting wire with a tensile structure includes a connecting wire main body. A connecting head is fixedly sleeved on the outer surface wall of the connecting wire main body. A plug is fixedly inserted into the inside of the connecting head. A braided sheath is arranged on the inner surface wall of the connecting wire main body. A plurality of longitudinal reinforcing ribs are fixedly connected to the inner surface wall of the braided sheath. A spiral winding layer is fixedly connected between the inner surface walls of the plurality of longitudinal reinforcing ribs.

[0009] Preferably, a waterproof and moisture-proof layer is adhesively connected to the inner surface wall of the fireproof layer.
[0010] Preferably, a tensile reinforcement layer is provided on the inner surface wall of the waterproof and moisture-proof layer.
[0011] Preferably, a basic protective layer is adhered to the inner surface wall of the tensile reinforcement layer.

[0013] 1. In the present utility model, through the interaction of the components of the connecting wire, the tensile performance of the connecting wire is significantly improved. The braided sheath is woven with polyester fiber to enhance wear resistance and tensile strength. The longitudinal reinforcing rib is made of thermoplastic elastomer, which effectively disperses the tensile force and improves the overall toughness. The spiral winding layer uses metal wires to construct a strong skeleton to enhance the anti-twisting ability, and the tensile cotton thread serves as an internal support to further disperse the tensile force and protect the wire. These components work together to form an efficient and stable tensile system, ensuring that the connecting wire can still maintain excellent stability and durability in a complex stress environment.

Detailed implementation mode
[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.
[0023] Embodiment 1, as Figures 1-4 shown, the present invention provides a connecting wire with a tensile structure, including a connecting wire body 1. A connector 2 is fixedly sleeved on the outer surface wall of the connecting wire body 1. A plug 3 is fixedly inserted inside the connector 2. A braided sheath 4 is arranged on the inner surface wall of the connecting wire body 1. A plurality of longitudinal reinforcing ribs 5 are fixedly connected to the inner surface wall of the braided sheath 4. A spiral winding layer 6 is fixedly connected between the inner surface walls of the plurality of longitudinal reinforcing ribs 5. An inner protection layer 7 is arranged on the inner surface wall of the spiral winding layer 6. A filling layer 8 is arranged on the inner surface wall of the inner protection layer 7. A group of conducting wires 9 are arranged on the inner surface wall of the filling layer 8. A tensile cotton thread 10 is arranged inside the filling layer 8.
[0024] The effects achieved by the entire Embodiment 1 are as follows. First, a braided sheath 4 is provided on the inner wall of the connection wire body 1. This braided sheath 4 is usually made of high-strength polyester fiber material through a precise braiding process. This braiding method not only endows the sheath with good tensile strength but also excellent wear resistance and weather resistance. A plurality of longitudinal reinforcing ribs 5 are fixedly connected to the bottom of the braided sheath 4. The plurality of longitudinal reinforcing ribs 5 are made of thermoplastic elastomer material. Thermoplastic elastomer has good elasticity and stretchability, can deform and absorb energy when subjected to tensile force, thereby dispersing the tensile force and protecting the connection wire body. And thermoplastic elastomer also has relatively high tensile strength, which can meet the usage requirements of the connection wire. Between the inner walls of the plurality of longitudinal reinforcing ribs 5, a spiral winding layer 6 is also fixedly connected. The spiral winding layer 6 is usually wound with metal wires such as copper wires, aluminum-magnesium alloy wires or high-strength synthetic fiber wires. This design can significantly improve the overall strength and anti-twisting ability of the cable while maintaining the flexibility of the connection wire. Further, the filling layer 8 inside the inner sheath 7 is made of a soft and elastic polyester fiber cotton material or the like. The main function of the filling layer 8 is to tightly wrap the conductor 9 to prevent it from being damaged due to movement or vibration. At the same time, it can also effectively isolate the intrusion of harmful substances such as external moisture and dust, protecting the conductor 9 from corrosion and aging. Inside the filling layer 8, a tensile cotton thread 10 is also provided. With its excellent tensile strength and good flexibility, the tensile cotton thread 10 can further enhance the overall tensile ability of the cable and provide an additional support point when the cable is subjected to tensile force, preventing the conductor 9 from breaking due to excessive stretching. This design further improves the durability and reliability of the connection wire.
[0025] Embodiment 2, as Figures 2-4 shown, the connection wire body 1 includes a wear-resistant layer 101. The inner wall of the wear-resistant layer 101 is adhesively connected with a fireproof layer 102. The inner wall of the fireproof layer 102 is adhesively connected with a waterproof and moisture-proof layer 103. The inner wall of the waterproof and moisture-proof layer 103 is provided with a tensile reinforcement layer 104. The inner wall of the tensile reinforcement layer 104 is adhesively connected with a basic protection layer 105.
[0026] The effect achieved by the entire Example 2 is that an abrasion-resistant layer 101 is provided on the outside of the connection line body 1. The abrasion-resistant layer 101 is made of a highly abrasion-resistant rubber material. This material directly faces the friction and scratching of the external environment with its excellent abrasion resistance, effectively protecting the internal structure from mechanical damage and significantly extending the service life of the connection line. An anti-fire layer 102 is adhered to the inner surface wall of the abrasion-resistant layer 101. The anti-fire layer 102 is made of a ceramized silicone rubber material. Ceramized silicon can quickly form a hard ceramic protection layer at high temperatures, having excellent fire resistance and self-extinguishing properties, thus effectively preventing the damage to the connection line in extreme situations such as fires and ensuring the safe and stable operation of the connection line. A waterproof and moisture-proof layer 103 is provided on the inner surface wall of the anti-fire layer 102. The waterproof and moisture-proof layer 103 is made of a waterproof and breathable membrane material. This material can not only effectively block the intrusion of moisture and dampness and keep the internal environment dry, but also has excellent breathability, allowing the connection line to dissipate heat normally in a humid environment. A tensile strength enhancement layer 104 is provided on the inner surface wall of the waterproof and moisture-proof layer 103. The tensile strength enhancement layer 104 is made of nylon fiber. Nylon fiber provides additional support and protection for the connection line with its excellent tensile strength and toughness. A basic protection layer 105 is adhered to the inner surface wall of the tensile strength enhancement layer 104. The basic protection layer 105 is made of polyethylene material. Polyethylene material provides basic electrical protection and chemical stability for the connection line with its excellent insulation, chemical resistance and processability, ensuring the purity of signal transmission and the long-term reliability of the connection line.
[0027] Working principle: When in use, first, a braided sheath 4 is provided on the inner surface wall of the connection line body 1. The braided sheath 4 is carefully braided from polyester fiber material. Through precise braiding technology, it not only endows the sheath with excellent tensile strength and wear resistance but also ensures good flexibility, enabling the connection line to still be able to flexibly cope with various stresses in a complex environment. Inside the braided sheath 4, multiple longitudinal reinforcing ribs 5 are evenly distributed along the length direction. These reinforcing ribs are made of thermoplastic elastomer material, which not only has high strength and excellent elasticity but also exhibits certain stretching performance, and can effectively disperse stress when the connection line is stretched or compressed, protecting the internal wire 9 from damage. In addition, the spiral winding layer 6 is made of metal wire, and this design significantly enhances the overall rigidity and anti-twisting ability of the connection line, ensuring the stability of signal transmission. At the same time, the filling layer 8 inside the inner protection layer 7 is made of a material with high elasticity and low compression deformation, which can closely adhere to and fix the wire 9, preventing it from moving or wearing during use. And inside the filling layer 8, tensile cotton threads 10 are also provided. These cotton threads not only enhance the overall tensile strength of the connection line but also, when the wire 9 is subjected to a sudden tensile force, serve as a second line of defense to absorb and disperse the tensile force, thereby further protecting the integrity and performance of the wire 9. Through the outer material structure of the connection line body 1, the wear-resistant layer 101, as the outermost layer, directly faces the external environment. Its high-wear-resistant rubber material effectively resists mechanical damages such as friction and scratching, extending the service life of the connection line. The fireproof layer 102 is provided inside the wear-resistant layer 101 and is made of ceramicized silicone rubber material, which has excellent fire resistance and self-extinguishing properties, and can protect the internal wire 9 from high-temperature damage in extreme situations such as fires. The waterproof and moisture-proof layer 103 is located inside the fireproof layer 102 and is made of a waterproof breathable film material, effectively blocking the intrusion of moisture and dampness, keeping the inside dry, and preventing the decline of electrical performance or corrosion problems. The tensile strengthening layer 104 is provided inside the waterproof and moisture-proof layer 103 and is made of nylon fiber, enhancing the overall tensile ability of the connection line with its high strength and toughness. Finally, the basic protection layer 105 is provided inside the tensile strengthening layer 104 and is made of polyethylene material, providing electrical insulation and chemical stability, ensuring the purity of signal transmission and the long-term reliability of the connection line.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
