Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire and cable technology, and in particular to a wire and cable with a bent sheath structure. Background Technology
[0002] Wires and cables with a bent sheath structure typically have conductors made of multiple strands of fine copper wire, such as oxygen-free bare copper wire, to ensure flexibility and conductivity. The insulation layer is often made of specially formulated PVC, TPE, or other high-mechanical-performance materials. The inner sheath can be made of armor-like extrusion molding such as TPU to fix the stranded wires and add tensile elements such as aramid fibers to enhance tensile strength. The shielding layer is made of high-conductivity tinned copper wire to shield against interference.
[0003] Traditional wires and cables rely on an electric field to conduct current or electrical signals by causing free electrons to move in a directional manner within the internal conductor (such as copper or aluminum). However, when cables are subjected to external forces such as bending, stretching, or vibration, the wires may shift within the sheath because they cannot be fixed in place. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a wire and cable with a bending sheath structure, which aims to improve the problem that traditional wires and cables will shift inside the sheath when subjected to external forces such as bending, stretching, and vibration.

A threaded hole is opened inside the fixing ring. A screw is threadedly connected inside the threaded hole. A fixing block is threadedly connected to the outer wall of the screw. A first connecting rod is fixedly connected inside the fixing block. A rotating ring is fixedly connected to the outer wall of the first connecting rod. Clamping components are provided on the inner and outer walls of the rotating ring.
[0007] Preferably, the clamping assembly includes a first support block, the outer wall of the first support block is fixedly connected to the inside of the rotating ring, a second connecting rod is fixedly connected to the outer wall of the first support block, a second support block is fixedly connected to the bottom end of the second connecting rod, and the outer wall of the second support block is fixedly connected to the inside of the support plate.
[0008] Preferably, a power cord is provided on the outer wall of the second connecting rod, and a third connecting rod is provided on the outer wall of the power cord.
[0009] Preferably, a first baffle is fixedly connected to the outer right side of the third connecting rod, and the outer wall of the first baffle is fixedly connected to the inside of the rotating ring.
[0010] Preferably, a second baffle is fixedly connected to the left outer wall of the third connecting rod, and the outer wall of the second baffle is fixedly connected to the inside of the fixing ring.
[0011] Preferably, the inside of the rotating ring is rotatably connected to the outer wall of the fixed ring, and the inside of the fixed ring is disposed on the outer wall of the power cord.
[0012] Preferably, the outer wall of the rotating ring is provided with a protective component.
[0013] Preferably, the protective component includes an insulating layer, the outer wall of which is sequentially connected to a bending layer, a waterproof layer, and a wear-resistant layer, and the interior of the insulating layer is fixedly connected to the lower surface of the support plate.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by rotating the screw, the connection between the rotating ring and the fixed ring is loosened, and then the fixed block is rotated to drive the first connecting rod to rotate. Then, the rotating ring rotates under the drive of the first connecting rod, and then the first support block rotates simultaneously with the rotation of the rotating ring. Finally, the purpose of clamping the power cord to prevent shaking can be achieved. By clamping the component, the wire will not move randomly due to external force, and always maintains an orderly arrangement, ensuring the integrity of the overall cable structure and effectively avoiding internal disorder caused by loose wires.
[0016] 2. In this utility model, the bending layer is fixed by the support of the insulation layer, and then the waterproof layer is fixed under the action of the bending layer. Subsequently, the wear-resistant layer will be fixed along with the waterproof layer. Finally, it can achieve the purpose of preventing damage when the wire is bent. It can effectively buffer and disperse the stress generated by bending, reduce the fatigue and breakage of the wire conductor, as well as the wear and cracking of the insulation layer, thereby significantly extending the service life of the wire.

[0025] Specifically, the support plate 1 is used to support and fix the fixing ring 2 to prevent the fixing ring 2 from shaking. The fixing ring 2 has a threaded hole 3 inside, which is used to connect the screw 4 to ensure that the rotating ring 7 is stably connected to the fixing ring 2. The fixing block 5 is used to support the screw 4 for fixing. The fixing block 5 is used to drive the first connecting rod 6 to rotate. The first connecting rod 6 is used to drive the rotating ring 7 to rotate. The first connecting rod 6 is used to drive the clamping assembly to adjust the tightness.
[0026] Reference Figures 2-4 The clamping assembly includes a first support block 8, the outer wall of which is fixedly connected to the inside of a rotating ring 7. A second connecting rod 9 is fixedly connected to the outer wall of the first support block 8. A second support block 10 is fixedly connected to the bottom end of the second connecting rod 9. The outer wall of the second support block 10 is fixedly connected to the inside of a support plate 1. A power cord 14 is provided on the outer wall of the second connecting rod 9. A third connecting rod 12 is provided on the outer wall of the power cord 14. A first baffle 11 is fixedly connected to the right outer wall of the third connecting rod 12. The outer wall of the first baffle 11 is fixedly connected to the inside of the rotating ring 7. A second baffle 13 is fixedly connected to the left outer wall of the third connecting rod 12. The outer wall of the second baffle 13 is fixedly connected to the inside of a fixed ring 2. The inside of the rotating ring 7 is rotatably connected to the outer wall of the fixed ring 2. The inside of the fixed ring 2 is located on the outer wall of the power cord 14.
[0027] Specifically, the rotating ring 7 drives the first support block 8 to rotate, the first support block 8 drives the second connecting rod 9 to rotate, the second support block 10 assists the second connecting rod 9 to rotate, the second support block 10 is fixed to the outer wall of the fixed ring 2, the rotating ring 7 drives the first baffle 11 to rotate, the first baffle 11 drives the third connecting rod 12 to rotate, the second baffle 13 assists the third connecting rod 12 to rotate, the third connecting rod 12 and the second connecting rod 9 clamp the power cord 14 and prevent the power cord 14 from shaking, thereby achieving the effect of clamping the power cord 14 to prevent shaking, and also ensuring the integrity of the overall cable structure, effectively avoiding internal disorder caused by loose wires.
[0028] Reference Figure 2 and Figure 4 The outer wall of the rotating ring 7 is provided with a protective component 15; the protective component 15 includes an insulating layer 16, and the outer wall of the insulating layer 16 is sequentially connected with a bending layer 17, a waterproof layer 18 and a wear-resistant layer 19, and the interior of the insulating layer 16 is fixedly connected to the lower surface of the support plate 1.
[0029] Specifically, the insulation layer 16 effectively isolates the conductor, preventing current leakage from the conductor to the outside or short circuits with other conductors. The bending layer 17 has good elasticity and resilience, and can continuously deform and return to its original shape when the cable is repeatedly bent, increasing the cable's bending resistance and ensuring that the cable can still be used normally under frequent bending conditions. The waterproof layer 18 effectively blocks external moisture from entering the cable, preventing the conductor, insulation layer 16, and other components from contacting water. The wear-resistant layer 19 resists wear, reducing the risk of damage to the cable due to surface wear, thereby significantly extending the cable's service life. This achieves the effect of preventing damage when the wire is bent and can effectively buffer and disperse the stress generated by bending.
[0030] Working principle: When using wires and cables with a bending sheath structure, first turn screw 4 to loosen the connection between rotating ring 7 and fixed ring 2, thereby driving rotating ring 7 to rotate, which in turn drives first connecting rod 6 to rotate, and simultaneously drives fixed block 5 to rotate, which in turn drives first support block 8 to rotate, which in turn drives second connecting rod 9 to rotate, thereby fixing second support block 10 to the outer wall of fixed ring 2, further driving first baffle 11 to rotate, which in turn drives third connecting rod 12 to rotate, which in turn drives second baffle 13 to be fixed to the outer wall of fixed ring 2, and then turn screw 4 again to fix rotating ring 7 and fixed ring 2, thereby achieving the effect of clamping power cord 14 to prevent shaking. Through the clamping component, the wire will not move randomly due to external force, and always maintains an orderly arrangement, ensuring the integrity of the overall cable structure and effectively avoiding internal disorder caused by loose wires;
[0031] The insulation layer 16 supports and fixes the bending layer 17, which in turn drives the bending layer 17 to support and fix the waterproof layer 18, thereby fixing the waterproof layer 18 to support and fix the wear-resistant layer 19. This can prevent damage when the wire is bent, effectively buffer and disperse the stress generated by bending, reduce the fatigue and breakage of the wire conductor, as well as the wear and cracking of the insulation layer 16, thus significantly extending the service life of the wire.
