Description

Technical Field

[0001] This utility model relates to the technical field of wire harnesses, specifically to a low-voltage wire harness isolation device. Background Technology

[0002] As the carrier connecting various components in a circuit, wire harnesses play a crucial role. They must not only accurately transmit various signals but also ensure the reliability of the connected circuits. Wire harnesses are divided into high-voltage wire harnesses and low-voltage wire harnesses. High-voltage wire harnesses generate a strong magnetic field, which may affect the current in low-voltage wire harnesses, thereby potentially affecting the signal transmission of low-voltage wire harnesses. Therefore, isolation devices are needed to isolate and protect low-voltage wire harnesses.

[0003] According to Chinese Patent No. CN222271989U, a low-voltage wiring harness isolation device for new energy vehicles includes a pipe and a wiring harness. Several partitions are arranged equidistantly on the outer side of the pipe. An arc-shaped cover plate is hinged to one end of each partition plate. The end of the arc-shaped cover plate is engaged with the end of another partition plate. The wiring harness has multiple fan-shaped areas that pass through the arc-shaped cover plate and a pair of partitions. Conductive foam pads that can be fitted are fixed to the inner side of the arc-shaped cover plate and both ends of the partitions. Several ventilation openings corresponding to the fan-shaped areas are provided on the outer side of the pipe. A fan is installed at the front end of the pipe.

[0004] In the above solution, by placing the wire harness in the fan-shaped area and then fixing its end by rotating the arc-shaped cover plate and engaging it with the snap-fit ​​slot, the following disadvantages are observed: the isolation device cannot isolate and protect low-voltage wire harnesses of different sizes during use, resulting in a reduction in the flexibility and practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a low-voltage wire harness isolation device to solve the problem that the current isolation device cannot isolate and protect low-voltage wire harnesses of different sizes, resulting in a reduction in the flexibility and practicality of the device.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a low-voltage wire harness isolation device, including a cover plate, the cover plate being detachably disposed on the top surface of a U-shaped seat, a plurality of pressure plates being movably disposed below the cover plate, an elastic arc plate being movably disposed below each of the pressure plates, a spring being fixed between each of the elastic arc plates and the pressure plates, a first conductive foam pad being fixed to the inner wall of the U-shaped seat, and a second conductive foam pad being fixed to the inner wall of each of the elastic arc plates.

[0007] Preferably, the top surfaces of the plurality of pressure plates are respectively provided with a plurality of first limiting holes, and the top surfaces of the plurality of elastic arc plates are respectively fixed with a plurality of first limiting posts, and the plurality of first limiting posts are slidably inserted into the plurality of first limiting holes.

[0008] Preferably, the top surfaces of the plurality of pressure plates are respectively provided with rotating grooves, the top surfaces of the cover plate are provided with a plurality of threaded holes, bolts are respectively threaded into the plurality of threaded holes, rotating blocks are respectively fixed to the bottom ends of the plurality of bolts, and the plurality of rotating blocks are respectively rotatably arranged in the plurality of rotating grooves.

[0009] Preferably, the top surface of the cover plate is provided with a plurality of second limiting holes, and the top surfaces of the plurality of pressure plates are respectively fixed with two second limiting posts, the second limiting posts being slidably inserted into the second limiting holes.

[0010] Preferably, a shielding layer is fixed to the inner wall of the cover plate.

[0011] Preferably, the top surface of the U-shaped seat is provided with a plurality of snap-fit ​​holes, and the bottom surface of the cover plate is fixed with a plurality of snap-fit ​​blocks, and the plurality of snap-fit ​​blocks are respectively detachably snapped into the plurality of snap-fit ​​holes.

[0012] Compared with the prior art, a low-voltage wire harness isolation device adopting the above technical solution has the following advantages:

[0013] Beneficial effects:

[0014] 1. In use, the combined use of the cover plate, U-shaped seat, pressure plate, elastic arc plate, spring, first conductive foam pad and second conductive foam pad is conducive to the stable isolation and protection of low-voltage wire harnesses of different sizes, effectively resisting the magnetic field interference generated by high-voltage wire harnesses, thereby improving the flexibility and practicality of the device.

[0015] Second, during use, the cooperation of the first limiting hole and the first limiting post facilitates the limiting of the elastic arc plate, preventing it from shifting during pressing, thereby improving the overall performance and reliability of the device. By rotating the bolt, the rotating block rotates inside the rotating groove, which allows the pressure plate to move downward, thereby driving the elastic arc plate to more tightly compress and fix the wire harness, improving the flexibility and operability of the device;

[0016] Thirdly, during use, the cooperation of the second limiting hole and the second limiting post facilitates the limiting of the pressure plate, effectively preventing it from shifting or swaying during lifting and lowering, ensuring stable and reliable fixation of the wire harness. The shielding layer is a metal braided mesh, which further enhances the electromagnetic shielding performance of the device, effectively blocking the intrusion of external electromagnetic interference and protecting the low-voltage wire harness from the magnetic field generated by the high-voltage wire harness. The cooperation of the snap-fit ​​hole and snap-fit ​​block facilitates quick assembly and disassembly of the cover plate and the U-shaped seat, simplifying the assembly and disassembly process and improving work efficiency.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, a low-voltage wiring harness isolation device includes a cover plate 1, which is detachably disposed on the top surface of a U-shaped seat 2. Several pressure plates 3 are movably disposed below the cover plate 1, and elastic arc plates 4 are movably disposed below each of the pressure plates 3. Springs 5 ​​are fixed between the elastic arc plates 4 and the pressure plates 3 respectively. A first conductive foam pad 6 is fixed to the inner wall of the U-shaped seat 2, and a second conductive foam pad 7 is fixed to the inner wall of each of the elastic arc plates 4.

[0024] In use, the operator first places the low-voltage wire harness to be isolated inside the U-shaped base 2, ensuring that the wire harness rests on the first conductive foam pad 6. Then, the cover plate 1 is installed on the top surface of the U-shaped base 2. At this point, the pressure plate 3 and the elastic arc plate 4, under the action of the cover plate 1, begin to compress and fix the wire harness. During this process, the spring 5 gradually compresses, while the elastic arc plate 4, with its elastic deformation capability, can flexibly adapt to wire harnesses of different sizes, ensuring that each wire harness is properly fixed. After the elastic arc plate 4 has finished compressing the wire harness, the second conductive foam pad 7 on its inner wall comes into close contact with the wire harness, forming an isolation barrier. Through the coordinated use of the cover plate 1, U-shaped base 2, pressure plate 3, elastic arc plate 4, spring 5, first conductive foam pad 6, and second conductive foam pad 7, it is beneficial to provide stable isolation protection for low-voltage wire harnesses of different sizes, effectively resisting magnetic field interference generated by high-voltage wire harnesses, thereby improving the flexibility and practicality of the device.

[0025] like Figures 1-4 As shown, several pressure plates 3 have several first limiting holes 8 on their top surfaces, and several elastic arc plates 4 have several first limiting posts 9 fixed on their top surfaces. The several first limiting posts 9 are slidably inserted into the several first limiting holes 8.

[0026] In use, the first limiting hole 8 and the first limiting post 9 work together to limit the elastic arc plate 4, preventing it from shifting when pressed, thereby improving the overall performance and reliability of the device.

[0027] like Figures 1-4 As shown, the top surfaces of several pressure plates 3 are respectively provided with rotating grooves 10, the top surface of the cover plate 1 is provided with several threaded holes 11, and bolts 12 are respectively threaded into the several threaded holes 11. The bottom ends of the several bolts 12 are respectively fixed with rotating blocks 13. The several rotating blocks 13 are respectively rotatably arranged in the several rotating grooves 10. The top surface of the cover plate 1 is provided with several second limiting holes 14, and the top surfaces of the several pressure plates 3 are respectively fixed with two second limiting posts 15. The second limiting posts 15 are slidably inserted into the second limiting holes 14.

[0028] In use, rotating the bolt 12 causes the rotating block 13 to rotate inside the rotating groove 10, which allows the pressure plate 3 to move downwards. This, in turn, causes the elastic arc plate 4 to more tightly compress and fix the wire harness, improving the flexibility and operability of the device. The cooperation between the second limiting hole 14 and the second limiting post 15 helps to limit the pressure plate 3, effectively preventing the pressure plate 3 from shifting or shaking during lifting and lowering, ensuring that the wire harness can be stably and reliably fixed.

[0029] like Figures 1-4As shown, a shielding layer 16 is fixed to the inner wall of the cover plate 1, and a number of snap-fit ​​holes 17 are opened on the top surface of the U-shaped seat 2. A number of snap-fit ​​blocks 18 are fixed to the bottom surface of the cover plate 1, and the number of snap-fit ​​blocks 18 are detachably snapped into the number of snap-fit ​​holes 17.

[0030] During use, the shielding layer 16 is a metal braided mesh, which further enhances the electromagnetic shielding performance of the device, effectively blocking the intrusion of external electromagnetic interference and protecting the low-voltage harness from the magnetic field generated by the high-voltage harness. The use of the snap-fit ​​hole 17 and the snap-fit ​​block 18 facilitates quick assembly and disassembly of the cover plate 1 and the U-shaped seat 2, simplifying the assembly and disassembly process and improving work efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
