[0002] Wire harnesses are a type of connecting wires used in electrical connections. However, existing wire harnesses have poor tensile strength, making them prone to damage when pulled by external forces. Damaged wire harnesses can lead to safety accidents. Currently, commonly used wire harnesses consist of conductive cores and an insulating layer. The conductive cores are made of single or multiple bundles of copper wires. Copper wires are thin and cannot withstand large tensile forces. Therefore, the industry usually improves the tensile strength of communication wire harnesses by reinforcing the insulation layer or adding a braided sleeve inside the insulation layer. These simple methods improve tensile strength to some extent, but the improvement is limited. When subjected to significant tension, they are prone to breakage.
[0003] Therefore, this utility model provides a tensile-resistant wire harness. Utility Model Content

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a tensile-resistant wire harness, including a wire harness body 1 and a protective structure. The protective structure includes a first protective sleeve 3 and a second protective sleeve 4. The second protective sleeve 4 is located inside the first protective sleeve 3. An auxiliary tensile core 2 is installed inside the second protective sleeve 4. The auxiliary tensile core 2 corresponds to the wire harness body 1. A reinforcing structure is installed on the first protective sleeve 3. Multiple limiting rings 9 are installed on the periphery of the first protective sleeve 3. A pressure plate 13 is installed on one side of the limiting ring 9. Multiple pull ropes 10 are installed between two adjacent pressure plates 13. The pull ropes 10 correspond to the first protective sleeve 3. A buffer structure is installed on the pressure plate 13.
[0022] In this embodiment, the wire harness body 1 is spirally wound around the periphery of the auxiliary tensile core 2, a first filling layer 5 is filled between the first protective sleeve 3 and the second protective sleeve 4, and a second filling layer 6 is filled between the second protective sleeve 4 and the wire harness body 1.
[0023] Specifically, the first protective sleeve 3 and the second protective sleeve 4 can provide dual protection. The first filling layer 5 and the second filling layer 6, together with the tensile structure of the wire harness body 1 itself, can achieve a good protective effect.
[0024] The reinforcing structure includes a reinforcing rib 7, which is located inside the first protective sleeve 3 and has a spiral structure.
[0025] The strength of the first protective sleeve 3 is enhanced by reinforcing rib 7 to prevent the first protective sleeve 3 from breaking.
[0026] The limiting ring 9 is slidably connected to the wire harness body 1. A fixing plate 8 is fixed on the limiting ring 9. The fixing plate 8 is located on one side of the wire harness body 1. An alarm 16 is fixed on the fixing plate 8. A first electrode plate 14 is fixed on the pressure plate 13. A second electrode plate 15 is fixed on the limiting ring 9. The alarm 16 is connected to the first electrode plate 14 and the second electrode plate 15 through wires. The buffer structure includes multiple springs 12. The two ends of the springs 12 are fixedly connected to the pressure plate 13 and the limiting ring 9, respectively. The two ends of the pull rope 10 are fixedly connected to the two pressure plates 13, respectively. The pull rope 10 is slidably connected to the limiting ring 9. Multiple pull ropes 10 are located around the first protective sleeve 3. A fixing ring 11 is installed around the first protective sleeve 3. The pull rope 10 is located between the fixing ring 11 and the first protective sleeve 3. The pull rope 10 is clamped on the first protective sleeve 3 by the fixing ring 11. The fixing plate 8 is fixed to the ground or wall by bolts.
[0027] Specifically, when pulled, the movement of the harness body 1 will cause the first protective sleeve 3 to move, thereby pulling the pull rope 10 to move, causing the first protective sleeve 3 to move the pressure plate 13, which can compress the spring 12 and play a certain buffering effect. At this time, the first electrode plate 14 and the second electrode plate 15 come into contact, causing the alarm 16 to sound an alarm, which can indicate that the harness body 1 is being pulled.
[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
