Description

Technical Field

[0001] This utility model relates to the field of wire harnesses, and in particular to an adjustable anti-interference wire harness. Background Technology

[0002] Existing wire harnesses typically have fixed output head types (such as a single Apple interface, Android interface, or Type-C interface). When different types of devices need to be connected, different wire harnesses need to be replaced, which limits the usage scenarios and is inconvenient to operate.

[0003] When transmitting data, existing wire harnesses are prone to electromagnetic interference between different transmission wire harnesses within the same harness. At the same time, the external electromagnetic environment can also interfere with data transmission, leading to signal attenuation, distortion, or even transmission interruption.

[0004] Traditional anti-interference magnetic rings are usually fixedly installed on data lines and cannot be adjusted according to the specific location of electromagnetic interference in actual use. They are difficult to specifically solve local strong interference problems and have limited anti-interference effect.

[0005] To address the problems in the prior art, a wire harness with flexible output interface adjustment and high-efficiency anti-interference is proposed. Utility Model Content

[0006] The main purpose of this invention is to address the problems of existing wire harness output heads being non-adjustable and having poor anti-interference capabilities.

[0007] To address the aforementioned problems, this utility model proposes an adjustable anti-interference wire harness, comprising an adjustable output head, a data cable, a combined anti-interference magnetic ring, and an input head. The data cable is connected to the rear of the adjustable output head, and the combined anti-interference magnetic ring is located on one side of the data cable, enclosing the data cable. An input head is located at the rear of the data cable. The adjustable output head includes a main body, with functional output heads slidably mounted on the front, top, bottom, left, and right sides of the main body. The rear ends of the functional output heads extend into the main body. Four buttons are located on the exterior of the main body. Each of the four support rods is fixedly connected to one end of the main body, and each of the four support rods is inserted into one of the four function output heads. The insertion points are provided with grooves. The outer surface of the main body has a sliding groove for the support rods to move. Each of the two sides of the support rod is fixedly connected to a locking post. The inner wall of the sliding groove has a corresponding locking slot for the locking post to move. A spring is provided at the end of the support rod away from the button, and the spring is located in the groove. The support rod is slidably connected to the rear end of the function output head through the groove. The main body has an active chamber for the corresponding function output head to move. A connecting wire is provided at the rear of the function output head and is connected to the power line inside the main body.

[0008] In one embodiment, the data line includes transmission harnesses inside, and multiple transmission harnesses are wrapped with anti-interference metal foil. The anti-interference metal foil is wrapped with an insulating sheath, and the outer surface of the data line is wrapped with an insulating outer sheath. An anti-interference metal mesh is disposed between the insulating outer sheath and the multiple transmission harnesses, and the anti-interference metal mesh wraps the multiple transmission harnesses.

[0009] In one embodiment, multiple transmission harnesses are made of materials with different anti-interference properties, and the corresponding anti-interference metal foil materials are also different.

[0010] In one embodiment, the combined anti-interference magnetic ring includes an outer wrapping layer. The two outer wrapping layers are made of the same material. Threaded rods are threaded through the four corners of the upper outer wrapping layer, and threaded holes are opened at the four corners of the lower outer wrapping layer. The four threaded rods are threaded into the four threaded holes respectively. The two outer wrapping layers are connected to each other through the threaded rods and threaded holes.

[0011] In one embodiment, a metal magnetic ring is disposed inside the outer wrapping layer, and an inner wrapping layer is disposed inside the metal magnetic ring, with the outer wrapping layer and the inner wrapping layer tightly wrapping the middle metal magnetic ring.

[0012] In one embodiment, the inner wrapping layer has a wrapping opening corresponding to the data cable on its inner side, and the inner wrapping layer is tightly fitted to the data cable through the wrapping opening.

[0013] Beneficial effects: 1. This utility model adopts an adjustable output head, which can be equipped with different types of functional output heads such as Apple, Android, and Type-C. The output head can be popped up and retracted through a button and spring structure. Users can quickly switch interfaces according to device needs without replacing the wiring harness, solving the problem of the single interface of traditional wiring harnesses. The output interface is flexible and adaptable, improving the convenience of use.

[0014] 2. The data cable of this utility model adopts a multi-layer structure of "anti-interference metal foil + insulation sheath + anti-interference metal mesh"; the anti-interference metal foil effectively resists the mutual interference between transmission harnesses by matching materials with different anti-interference coefficients to the electromagnetic interference generated by transmission harnesses of different materials; the anti-interference metal mesh is wrapped around the outside of the transmission harness to reduce the interference of the external electromagnetic environment on the signal; the insulation sheath and the outer insulation sheath isolate the internal harness from the external environment, further avoiding short circuits or external damage. The multi-layer structure works together to significantly improve the stability of data transmission.

[0015] The modular anti-interference magnetic ring is detachable and can be assembled via a threaded rod. Its installation position can be flexibly adjusted according to the electromagnetic interference intensity at different locations on the data cable, effectively addressing localized strong interference issues. Compared to traditional fixed magnetic rings, it offers higher anti-interference efficiency and a wider range of applications. The magnetic ring and cable harness are tightly fitted: the inner sheath of the modular anti-interference magnetic ring fits snugly against the data cable through a sheath opening, preventing the metal magnetic ring from sliding and ensuring the continuity and stability of the anti-interference effect. This avoids a decrease in anti-interference performance due to magnetic ring displacement. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To achieve the above-mentioned utility model objectives, such as Figure 1-6 As shown, this utility model provides an adjustable anti-interference wire harness, including an adjustable output head 1, a data cable 2, a combined anti-interference magnetic ring 3, and an input head 4. The data cable 2 is connected to the rear side of the adjustable output head 1. The combined anti-interference magnetic ring 3 is provided on one side of the data cable 2 and is wrapped around the outside of the data cable 2. The input head 4 is provided at the rear end of the data cable 2. The adjustable output head 1 includes a main body 23. Functional output heads 5 are slidably installed on the front end, top and bottom, and left and right sides of the main body 23. The rear ends of the functional output heads 5 extend into the main body 23. Four buttons 9 are provided on the outside of the main body 23. The four buttons 9 are fixedly connected to the end near the main body 23. There are four support rods 10, which are respectively inserted into the four function output heads 5. The insertion points are provided with grooves 8. The outer surface of the main body 23 is provided with a sliding groove 6 for the support rods 10 to move. The two sides of the support rods 10 are fixedly connected with locking posts 11. The inner wall of the sliding groove 6 is provided with a corresponding locking groove 13 for the locking posts 11 to move. A spring 12 is provided at the end of the support rod 10 away from the button 9. The spring 12 is located in the groove 8. The support rods 10 are slidably connected to the rear end of the function output head 5 through the groove 8. The main body 23 is provided with a corresponding movable chamber 7 for the function output head 5 to move. A connecting wire 14 is provided on the rear side of the function output head 5. The connecting wire 14 is connected to the power line inside the main body 23. In this embodiment, both sides of the outer end of the card slot 13 are connected to limit ports. When the card post 11 is on both sides of the slide groove 6, when the support rod 10 slides to both ends of the card slot 13, the spring 12 pushes the support rod 10 to move upward, and the card post 11 is pushed into the limit port for limitation. In the limited state, the function output head 5 is restricted by the support rod 10 and cannot move. Pressing the button 9 can push the card post 11 out of the limit port. At this time, pushing the button 9 back and forth can drive the function output head 5 at the lower end of the support rod 10 to move back and forth together, thereby achieving the purpose of popping out and storing the function output head 5. The function output head 5 are all common output heads on the market, such as Apple output head, Android output head, Type-C output head, etc., and the corresponding output head can be adjusted according to the usage requirements.

[0021] like Figure 5As shown, the data cable 2 includes a transmission harness 18 inside, and multiple transmission harnesses 18 are wrapped with an anti-interference metal foil 17. The anti-interference metal foil 17 is wrapped with an insulating sheath 16. The outer surface of the data cable 2 is wrapped with an insulating outer sheath 24. An anti-interference metal mesh 15 is provided between the insulating outer sheath 24 and the multiple transmission harnesses 18. The anti-interference metal mesh 15 wraps the multiple transmission harnesses 18. In this embodiment, electromagnetic interference is generated when the transmission harness 18 transmits data. The anti-interference metal foil 17 can resist the interference between multiple transmission harnesses 18, the anti-interference metal mesh 15 can reduce the electromagnetic interference of the external electromagnetic environment on the transmission harness 18, the insulating sheath 16 ensures that the various transmission harnesses 18 will not come into contact with each other, thus protecting the transmission harnesses 18, and the insulating outer sheath 24 protects the internal harnesses.

[0022] like Figure 5 As shown, the multiple transmission harnesses 18 are made of materials with different anti-interference properties, and the corresponding anti-interference metal foils 17 are also made of different materials; In this embodiment, the electromagnetic interference generated by each transmission harness 18 is different during operation, and the anti-interference coefficient of different anti-interference metal foils 17 is also different. It is necessary to use the corresponding anti-interference metal foil 17 according to the different transmission harness 18 materials.

[0023] like Figure 6 As shown, the combined anti-interference magnetic ring 3 includes an outer wrapping layer 19. The two outer wrapping layers 19 are made of the same material. The upper outer wrapping layer 19 has threaded rods 22 running through its four corners. The lower outer wrapping layer 19 has threaded holes at its four corners. The four threaded rods 22 are threaded into the four threaded holes respectively. The two outer wrapping layers 19 are connected to each other through the threaded rods 22 and the threaded holes. In this embodiment, the combined anti-interference magnetic ring 3 can be disassembled and assembled in two parts by means of the threaded rod 22, and the position of the combined anti-interference magnetic ring 3 on the data line 2 can be adjusted, which can solve the problem of large electromagnetic interference at a certain position on the data line 2.

[0024] like Figure 6 As shown, a metal magnetic ring 21 is provided inside the outer wrapping layer 19, and an inner wrapping layer 20 is provided inside the metal magnetic ring 21. The outer wrapping layer 19 and the inner wrapping layer 20 tightly wrap the middle metal magnetic ring 21.

[0025] like Figure 6 As shown, the inner wrapping layer 20 has a wrapping opening corresponding to the data cable 2 on its inner side, and the inner wrapping layer 20 is tightly attached to the data cable 2 through the wrapping opening; In this embodiment, the assembled metal magnetic ring 21 is tightly fitted with the data cable 2, and the metal magnetic ring 21 will not slide freely on the data cable 2.

[0026] Working principle: Data is input to the input head 4 and transmitted to the adjustable output head 1 via the data cable 2. During this process, the anti-interference metal foil 17 and anti-interference metal mesh 15 inside the data cable 2 work together with the combined anti-interference magnetic ring 3 to reduce interference generated between the environment and the wire harness. Then, the adjustable output head 1 is adjusted to the required function output head 5. The function output head 5 is connected to the corresponding device to complete the data transmission.
