Description

[0002] In modern society, wires and cables are used in a wide range of applications. Whether in industrial production, construction facilities, transportation or family life, wires and cables play a vital role. However, in many cases, wires and cables need to pass through bends, such as at the corners of buildings, at the connection points of equipment, in the narrow spaces of vehicles, etc. These bends are often prone to damage to wires and cables, affecting their normal use and lifespan.
[0003] In order to protect the bends of wires and cables, silicone rubber is usually used to protect the outer sheath of wires and cables, so that the wires and cables maintain their good elasticity when bent and are not easy to break. However, at the corners of buildings or objects, when the wires and cables are bent, part of their areas will be against the edge of the corner (the corner here can be regarded as an extremely thin linear edge) and squeezed with the edge of the corner. Therefore, after a long time, the wires and cables will still have creases, and the insulation layer at the creases will become thinner or have tiny cracks due to squeezing. Over time, these cracks will gradually expand, resulting in reduced insulation performance, and leakage or short circuit accidents are prone to occur. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides a technical solution:
[0024] See also Figure 1-Figure 4 As shown, a wire and cable capable of protecting a bending portion includes a wire body 1 and an arc-shaped partition 2, the inner wall of which is in close contact with the outer wall of the wire body 1; two inclined plates 3 are respectively located at the two ends of the arc-shaped partition 2, and the outer walls of the inclined plates 3 are against the arc-shaped partition 2.
[0025] Move the arc partition 2 to the part of the wire body 1 that needs to be bent, and then make the outer wall of the arc partition 2 butt against the corner. Since the folding angle of the wire body 1 is very small when it is bent at an extremely small corner, the wire body 1 is in a highly compressed state, and is therefore more susceptible to damage. However, if the arc partition 2 is placed between the wire body 1 and the corner, the bending angle can be effectively increased. At this time, the wire body 1 is like finding a strong support, and the pressure at the bend can be dispersed, greatly reducing the risk of damage.
[0026] When the wire body 1 is bent at the edge of the arc-shaped partition 2, since the inclined plate 3 is in an inclined state, the bent area of the wire body 1 can be supported. After the wire body 1 is supported, the folding angle between the wire body 1 and the edge of the arc-shaped partition 2 can be expanded, and the force points between the wire body 1 and the edge of the arc-shaped partition 2 can be reduced, thereby further protecting the wire body 1 from damage due to bending.
[0027] See also Figure 2 The arc partition plate 2 is provided with two arc grooves 5, one end of the inclined plate 3 extends into the arc groove 5, a fixing rod 6 is fixedly installed on the inner bottom wall of the arc groove 5, the inclined plate 3 is provided with a square opening 7, the fixing rod 6 is located inside the square opening 7 and abuts against the inner wall of the square opening 7.
[0028] The inclined plate 3 is put on the fixing rod 6 through the square opening 7 to prevent the inclined plate 3 from falling off the arc partition 2. When the wire body 1 is passed through the socket in the building, the inclined plate 3 can be tilted toward the arc partition 2, and then the square opening 7 will swing along the fixing rod 6. When the inclined plate 3 is moved to a parallel state, the wire body 1 and the arc partition 2 can be inserted into the socket in the building to prevent the inclined inclined plate 3 from blocking the socket and causing the arc partition 2 to be unable to enter the socket.
[0029] See also Figure 4 A first arc baffle 15 is fixedly installed at one end of the inclined plate 3, and a second arc baffle 16 is fixedly installed on the inner wall of the arc groove 5. The second arc baffle 16 is located at the edge of the arc groove 5, and the first arc baffle 15 is located inside the arc groove 5 and abuts against the outer wall of the second arc baffle 16.
[0030] The second arc baffle 16 blocks the first arc baffle 15 to prevent the inclined plate 3 from sliding out of the arc groove 5. When the first arc baffle 15 abuts against the second arc baffle 16, the inclined plate 3 can be kept in an inclined state.
[0031] See also Figure 1-Figure 4 An elastic band 4 is fixedly installed on the top of the arc-shaped partition 2, and the inner wall of the elastic band 4 is in close contact with the outer wall of the wire body 1, and the wire body 1 is located between the arc-shaped partition 2 and the elastic band 4.
[0032] The elastic band 4 enables the arc partition 2 to be tightly mounted on the wire body 1, which not only allows the arc partition 2 to be moved, but also prevents the arc partition 2 from falling from the wire body 1, and the arc partition 2 can be moved to the bend on the wire body 1 at any time.
[0033] See also Figure 2 An annular plate 8 is fixedly mounted on the outer wall of the square opening 7 . The annular plate 8 is located on the top of the fixing rod 6 . The area of the annular plate 8 is larger than that of the square opening 7 .
[0034] The annular plate 8 blocks the top of the fixing rod 6 to prevent the inclined plate 3 from sliding off the fixing rod 6 .
[0035] See also Figure 3 A plurality of wire cores 9 are arranged inside the wire body 1 , a filling layer 10 is filled between the plurality of wire cores 9 , an insulating layer 11 is fixedly connected to the outer wall of the filling layer 10 , and a shielding layer 12 is fixedly connected to the outer wall of the insulating layer 11 .
[0036] The filling layer 10 is used to fill the gaps between the multiple wire cores 9 to make the wire cores 9 tighter. The insulating layer 11 wraps the filling layer 10 to prevent the filling layer 10 from scattering and make the filling layer 10 tighter. At the same time, the insulating layer 11 can also insulate the wire core 9 to ensure that the current is stably transmitted in the wire core 9 and prevent the current from leaking to the surrounding environment. There are various electromagnetic fields around the wire body 1, such as high-voltage transmission lines, electrical equipment, radio waves, etc. These external electromagnetic fields may induce noise currents in the wire body 1 and interfere with the signals transmitted in the wire body 1. Therefore, the shielding layer 12 can effectively block the intrusion of external electromagnetic fields, reduce this induced noise, and ensure the accuracy and stability of signal transmission.
[0037] See also Figure 3 The outer wall of the shielding layer 12 is fixedly connected with an elastic layer 13, and the outer wall of the elastic layer 13 is fixedly connected with a sheath layer 14. The elastic layer 13 is made of a thermoplastic elastomer material, and the sheath layer 14 is made of a thermoplastic polyurethane material.
[0038] The elastic layer 13 of the thermoplastic elastomer has excellent elasticity. When the wire body 1 is bent, the elastic layer 13 can be deformed accordingly, and quickly return to its original shape after the bending force is removed, which makes it difficult for the wire body 1 to be permanently deformed in an environment with frequent bending. The sheath layer 14 of thermoplastic polyurethane material has excellent tensile strength and tear resistance, which makes the wire body 1 able to withstand large external pulling, extrusion and wear, and is not easy to be damaged during installation and use. Whether in a complex industrial environment or in daily household wiring, it can provide reliable protection for the wire body 1.
[0039] See also Figure 3 , multiple cores 9 are twisted and wound together in the shape of hemp ropes.
[0040] This twisted winding method allows each wire core 9 to share the pulling force when the cable body 1 is pulled by external force, greatly enhancing the overall tensile strength of the cable body 1. Whether it is dragged during installation or subjected to unexpected pulling force during use, the structural integrity can be better maintained and it is not easy to be pulled apart.
[0041] Working principle:
[0042] Move the arc partition 2 to the part of the wire body 1 that needs to be bent, and then make the outer wall of the arc partition 2 butt against the corner. Since the folding angle of the wire body 1 is very small when it is bent at an extremely small corner, the wire body 1 is in a highly compressed state, and is therefore more susceptible to damage. However, if the arc partition 2 is placed between the wire body 1 and the corner, the bending angle can be effectively increased. At this time, the wire body 1 is like finding a strong support, and the pressure at the bend can be dispersed, greatly reducing the risk of damage.
[0043] When the wire body 1 is bent at the edge of the arc-shaped partition 2, since the inclined plate 3 is in an inclined state, the bent area of the wire body 1 can be supported. After the wire body 1 is supported, the folding angle between the wire body 1 and the edge of the arc-shaped partition 2 can be expanded, and the force points between the wire body 1 and the edge of the arc-shaped partition 2 can be reduced, thereby further protecting the wire body 1 from damage due to bending.
[0044] The inclined plate 3 is put on the fixing rod 6 through the square opening 7 to prevent the inclined plate 3 from falling off the arc partition 2. When the wire body 1 is passed through the socket in the building, the inclined plate 3 can be tilted toward the arc partition 2, and then the square opening 7 will swing along the fixing rod 6. When the inclined plate 3 is moved to a parallel state, the wire body 1 and the arc partition 2 can be inserted into the socket in the building to prevent the inclined inclined plate 3 from blocking the socket and causing the arc partition 2 to be unable to enter the socket.
