Description

Technical Field

[0001] The invention relates to the technical field of automobile wiring harnesses, in particular to an anti-interference automobile wiring harness structure based on an adjustable double-layer jacket structure. Background Art

[0002] With the development of intelligent and electrified vehicles, the wiring harness used to connect components inside the car faces the challenges of complex electromagnetic interference and spatial layout. As the automotive industry rapidly advances towards intelligent and electrified vehicles, automotive wiring harnesses, as the nerves of the vehicle electrical system, undertake key functions of power transmission and signal interaction. Therefore, the stability and reliability of the wiring harness system directly affect the performance and safety of the entire vehicle. However, the complex vehicle environment places higher demands on wiring harnesses. Electromagnetic interference generated by power components such as engines and motors, and high-frequency signals from equipment such as vehicle-mounted radars and 5G communication modules can easily produce electromagnetic coupling with wiring harnesses. At the same time, the limited installation space in the vehicle requires a compact wiring harness layout to avoid vibration wear or signal crosstalk caused by loose wiring harnesses. However, the magnetic rings installed on the wiring harness to suppress high-frequency interference are often difficult to accurately match the interference source frequency with the wiring harness path because their fixed position cannot be adjusted. In addition, the dispersed arrangement of the magnetic rings will make the overall structure of the wiring harness loose, which is prone to displacement in the vehicle vibration environment, resulting in poor contact between the magnetic rings and the wiring harness, weakening the anti-interference performance. Summary of the Invention

[0003] The object of the present invention is to provide an anti-interference automobile wiring harness structure based on an adjustable double-layer jacket structure, so as to solve the problem in the above background technology that the magnetic ring is difficult to adjust and easy to move.

[0005] Preferably, a buckle is fixedly mounted on the outer surface of one end of the shell, and the buckle is engaged with the other end of the shell, the magnets are fitted together, and the outer surface of the magnets is fitted with the outer surface of the pipe.

[0006] By adopting the above technical solution, the shells can be snapped together through the setting of the snap fasteners, so that the magnets can be connected to each other and form a closed loop, so that the shell can be fixed on the outer surface of the pipe, and through the snap fit between the pipe and the shell, the shell will not move arbitrarily on the outer surface of the outer bellows after being fixed. At the same time, the shells and magnets of different materials and specifications can be replaced according to different usage requirements, and the magnets of different materials and specifications can be replaced according to the usage scenarios and needs, thereby improving the convenience and flexibility of use.

Grounding wires are fixedly installed on the outer surfaces of both ends of the shielding net, and the grounding wires are respectively connected to the first connector and the second connector.

[0008] By adopting the above technical solution, the metal strip can be inserted into the interior of the flexible connector strip and folded, so that the two ends of the shielding net can be fixed together. By overlapping and docking the two ends of the shielding net, the external signal can be blocked and shielded without causing the shielding net to explode due to the bending of the wire harness. The shielding net can also reduce the chance of wear and damage caused by random movement of the cable.

[0009] Preferably, an aluminum foil layer is fixedly provided on the inner surface of the outer corrugated tube, and a wear-resistant insulating layer is fixedly provided on the outer surface of the aluminum foil layer, and the outer surface of the wear-resistant insulating layer is in contact with the outer surface of the shielding mesh.

[0010] By adopting the above technical solution, multiple signals can be reflected through the use of the aluminum foil layer, and the probability of the aluminum foil layer being worn and penetrated can be reduced by setting the wear-resistant insulating layer. The outer corrugated tube can also provide the cable with waterproof, dustproof and wear-proof protection again, so that multiple cables can be shielded by the aluminum foil layer, reducing the impact of the signal on the cable and protecting the cable.

[0011] Preferably, a sponge barrier layer is installed on the outer surface of the outer bellows, and the sponge barrier layer and the outer bellows are concentrically designed. The outer surface of the outer bellows fits tightly with the outer surface of the sponge barrier layer, and one end of the sponge barrier layer is conical.

[0015] Preferably, heat shrink tubes are installed on the outer surfaces of both ends of the outer corrugated tube, and a hot-melt sealing layer is fixedly provided on the outer surface of the heat shrinkable tube, and the outer surface of the hot-melt sealing layer is in contact with the outer surface of the outer corrugated tube, the outer surface of the hot-melt sealing layer is in contact with the outer surface of the sponge barrier layer, and the hot-melt sealing layer is in contact with the outer surface of the cable.

[0016] By adopting the above technical solution, the heat shrinkage of the heat shrinkable tube and the hot melt property of the hot melt sealing layer are used to allow the heat shrinkable tube to shrink and cover the outer corrugated tube and the sponge barrier layer, and the hot melting of the hot melt sealing layer can further eliminate the gap between the outer corrugated tube and the sponge barrier layer, thereby reducing the chance of water and dust entering the outer corrugated tube.

[0017] Preferably, an airbag is fixedly installed inside the tube, and the airbag and the tube are concentrically designed. An inflation and deflation nozzle is fixedly installed on the outer surface of the airbag, and the inflation and deflation nozzle passes through the outer surface of the tube, and the outer surface of the inflation and deflation nozzle does not fit the outer surface of the shell.

[0018] By adopting the above technical solution, air can be injected into the interior of the airbag through the inflation and deflation nozzle, so that the airbag can expand and wrap and push the shielding net and cable in a ring state, so that the cable can be gathered and located at the center of the magnet, converting the interference signal energy into heat energy. Compared with the state of cable offset, the signal elimination efficiency can be improved. In addition, the flexible wrapping of the bag also effectively avoids the direct squeezing of the cable by metal parts, ensuring the mechanical integrity of the wiring harness while ensuring that the magnet exerts the best signal suppression performance.

[0020] By adopting the above technical solution, the support cup can be connected to the vehicle through an elastic plug-in card. At the same time, the use of the support cup and the elastic plug-in card allows the support cup to adjust its position along the direction of the outer bellows, allowing the outer bellows to be flexibly arranged in the vehicle.

[0021] Preferably, binding holes are provided on the outer surfaces of both ends of the support cup, and cable ties are inserted into the binding holes, and the outer surfaces of the cable ties are respectively in contact with the outer surfaces of the support cup and the outer corrugated tube.

[0022] By adopting the above technical solution, through the use of the binding hole, when the cable tie passes through the binding hole, the outer corrugated tube and the supporting cup can be connected and fixed to each other, and the cable tie will not fall off after being fixed through the binding hole and can be fixed more firmly.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the anti-interference automobile wiring harness structure based on the adjustable double-layer jacket structure: 1. The use of an outer bellows can provide additional protection for the cable and allow the cables to be gathered together, reducing the chance of damage due to movement and friction. At the same time, the length of the outer bellows can be cut according to the installation position of the magnet, and the outer bellows can be connected through pipe fittings and elastic plug connectors. After the installation and connection are completed, the outer shell and magnet are installed on the outer surface of the pipe fitting, so that the position of the magnet can be adjusted according to the use requirements to achieve the best signal suppression performance, so that the position of the magnet can be adjusted according to the use requirements of the automobile wiring harness; 2. The tapered design at one end of the sponge barrier layer allows it to be easily inserted into the outer corrugated tube. The split slots allow the cables and ground wires to be neatly arranged and engaged, eliminating gaps between the ground wire, cable, and outer corrugated tube. This prevents external dust, oil, and water from entering the outer corrugated tube, reducing the chance of cable erosion and damage and extending its service life. 3. By using the heat shrink tubing, the heat shrink tubing can hold the sponge barrier layer and the outer corrugated tube tightly after shrinking. At the same time, when the heat shrink tubing is heated, the hot melt sealing layer can be melted, allowing the hot melt sealing layer to adhere to the cable, the outer corrugated tube and the sponge barrier layer, further improving the connection strength and sealing between the cable, the outer corrugated tube and the sponge barrier layer, and reducing the movement of the cable inside the outer corrugated tube due to pulling and movement. 4. The airbag can be inflated and deflated through the air nozzle, allowing it to expand in a ring shape, allowing the airbag to push the cable and shielding mesh to move to the center of the magnet. Compared with the offset state of the cable in the magnet, the signal cancellation efficiency can be improved, ensuring mechanical integrity while ensuring that the magnet can achieve optimal signal suppression performance; 5. By inserting the metal strip into the groove of the flexible connector and bending it, the two ends of the shielding net can overlap and connect with each other, so that the shielding net can form a closed loop. After the first connector and the second connector are plugged in through the grounding wire, the shielding net can be grounded, so that external signals can be blocked, ensuring that the signal transmitted by the cable is not affected. The shielding net will not be opened when the cable is bent. At the same time, multiple cables can be wrapped with the shielding net; 6. The shell and magnet can be connected to each other through the buckle, so that the shell and magnet can be fixed on the outer surface of the pipe. The magnets of different materials and specifications can be adjusted or replaced according to different usage requirements, so that the cable can be used in different positions in the vehicle, improving the flexibility and diversity of use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-12 The present invention provides a technical solution: an anti-interference automotive wiring harness structure based on an adjustable double-layer jacket structure, including a cable 1, an outer corrugated tube 2 is inserted into the outer surface of the cable 1, and a pipe 13 is installed on the outer surface of the outer corrugated tube 2, and the outer surface of the pipe 13 is in contact with the outer surface of the outer corrugated tube 2, a first connector 25 is fixedly installed on the outer surface of one end of the cable 1, a second connector 26 is fixedly installed on the outer surface of the cable 1 away from the first connector 25, elastic plug connectors 14 are fixedly installed on the outer surfaces of both ends of the pipe 13, and the elastic plug connector 14 is engaged with the outer corrugated tube 2, a groove is provided on the outer surface of the pipe 13, and an outer surface of the pipe 13 is engaged with an outer shell 17, and a magnet 18 is fixedly provided inside the outer shell 17.

[0028] The provision of the outer bellows 2 can provide additional protection for multiple cables 1, reducing the chance of damage to the cables 1 due to movement inside the vehicle, and the outer bellows 2 can be cut according to the length of the cables 1. The pipe 13 and the outer bellows 2 can be connected and firmly assembled through the elastic plug connector 14, so that the position of the outer shell 17 and the magnet 18 on the cable 1 can be adjusted according to the placement requirements during use to achieve optimal signal suppression performance. When the cable 1 is used in different places inside the vehicle, the position of the outer shell 17 and the magnet 18 can be adjusted according to the requirements of use, so that the outer shell 17 and the magnet 18 can be flexibly adjusted.

[0029] A buckle 19 is fixedly mounted on the outer surface of one end of the housing 17 , and the buckle 19 is engaged with the other end of the housing 17 . The magnets 18 are in contact with each other, and the outer surface of the magnet 18 is in contact with the outer surface of the pipe 13 .

[0030] By using the clip 19, the shell 17 and the magnet 18 can be interlocked and fixed together, so that the magnet 18 forms a ring, so that the magnet 18 and the shell 17 can be fixed to the outer surface of the pipe 13. The magnet 18 and the shell 17 of different materials and sizes can be replaced according to the use environment and needs, thereby improving the convenience and flexibility of use to meet different usage needs.

[0031] The outer surface of the cable 1 is fitted with a shielding net 3, and a flexible plug-in strip 4 is fixedly installed on the outer surface of the shielding net 3, and grooves are evenly opened on the outer surface of the flexible plug-in strip 4. The outer surface of the shielding net 3 at one end away from the flexible plug-in strip 4 is evenly fixed with a metal strip 5, and the metal strip 5 is plugged into the groove of the flexible plug-in strip 4. The outer surfaces of the shielding nets 3 overlap with each other, and the outer surfaces of the shielding nets 3 fit each other. Grounding wires 24 are fixedly installed on the outer surfaces of both ends of the shielding net 3, and the grounding wires 24 are respectively connected to the first connector 25 and the second connector 26.

[0032] By inserting the metal strip 5 into the groove of the flexible connector strip 4 and folding the metal strip 5, the two ends of the shielding net 3 can be connected to each other and stacked to form an inner layer. Through the connection of the shielding net 3, when the automobile wiring harness is bent, the opening will not cause the entry of mixed low-frequency signals, so that the shielding net 3 can block and intercept external signals, and can wrap a plurality of cables 1. Through the connection of the grounding wire 24, the first connector 25 and the second connector 26, the shielding net 3 can be connected to the ground, so that the cable 1 can be completely wrapped by the shielding net 3 and block the low-frequency signal, so that the signal transmission between the lines will not be affected by the low-frequency signal.

[0033] An aluminum foil layer 6 is fixedly provided on the inner surface of the outer corrugated tube 2 , and a wear-resistant insulating layer 7 is fixedly provided on the outer surface of the aluminum foil layer 6 , and the outer surface of the wear-resistant insulating layer 7 is in contact with the outer surface of the shielding mesh 3 .

[0034] The aluminum foil layer 6 can efficiently reflect high-frequency electromagnetic signals, radio frequency signals and electrostatic fields above 100MHz to block interference generated by equipment such as vehicle-mounted radars and communication modules, ensuring the stability of signal transmission of the cable 1. At the same time, the wear-resistant insulating layer 7 improves the durability of the aluminum foil layer 6. The wear-resistant insulating layer 7 on the outside isolates sharp objects from direct contact with the aluminum foil layer 6, so that the aluminum foil layer 6 will not be worn and penetrated, and the outer corrugated tube 2 further constructs a protection system to resist the impact of sand and gravel and the erosion of oil, providing physical protection and environmental isolation for the cable 1. The synergistic effect of the three makes the bundled cable 1 obtain all-round electromagnetic shielding protection, and maintain structural integrity in a complex vehicle environment, effectively reducing the influence of signal interference and external factors on the performance of the wiring harness.

[0035] A sponge barrier layer 8 is installed on the outer surface of the outer bellows 2, and the sponge barrier layer 8 and the outer bellows 2 are concentrically designed. The outer surface of the outer bellows 2 fits tightly with the outer surface of the sponge barrier layer 8, and one end of the sponge barrier layer 8 is tapered.

[0036] Through the conical design of the sponge barrier layer 8, the sponge barrier layer 8 can be more easily inserted into the two ends of the outer corrugated tube 2, so that the sponge barrier layer 8 can seal the outer corrugated tube 2, preventing dust, oil, etc. from entering the interior of the outer corrugated tube 2 and causing damage to the cable 1, thereby improving the service life of the cable 1.

[0037] The outer surface of the sponge barrier layer 8 is evenly provided with cutting slots 9, and the outer surface of the cutting slots 9 is interspersed with cables 1, and the outer surface of the cable 1 is tightly fitted with the outer surface of the cutting slots 9, and marking labels 12 are fixed to both ends of the cable 1.

[0038] By using the splitting slot 9, the cable 1 can be fixed and the gap between the cable 1 and the outer corrugated tube 2 can be eliminated, so that the cable 1 can be arranged neatly. At the same time, the gap between the cable 1 and the outer corrugated tube 2 can be eliminated. At the same time, the marking label 12 can facilitate the detection and search of the cable 1 during maintenance, thereby improving the convenience during maintenance and further improving the sealing of the outer corrugated tube 2.

[0039] The outer surfaces of both ends of the outer corrugated tube 2 are plugged with heat shrinkable tubes 10, and the outer surface of the heat shrinkable tube 10 is fixedly provided with a hot-melt sealing layer 11, and the outer surface of the hot-melt sealing layer 11 is in contact with the outer surface of the outer corrugated tube 2, the outer surface of the hot-melt sealing layer 11 is in contact with the outer surface of the sponge barrier layer 8, and the hot-melt sealing layer 11 is in contact with the outer surface of the cable 1.

[0040] By using the heat shrink tube 10, the outer corrugated tube 2 and the sponge barrier layer 8 can be sealed, and the cable 1 can be gathered at the same time. At the same time, the hot-melt sealing layer 11 can strengthen the connection strength between the outer corrugated tube 2, the sponge barrier layer 8 and the cable 1, and prevent the cable 1 from moving at will.

[0041] An airbag 15 is fixedly installed inside the tube 13, and the airbag 15 and the tube 13 are concentrically designed. An inflation and deflation nozzle 16 is fixedly installed on the outer surface of the airbag 15, and the inflation and deflation nozzle 16 passes through the outer surface of the tube 13. The outer surface of the inflation and deflation nozzle 16 does not fit the outer surface of the shell 17.

[0042] The airbag 15 can be inflated and deflated through the inflation and deflation nozzle 16, so that the airbag 15 can gradually expand in a circular shape. The cable 1 and the shielding net 3 are gradually gathered together through the expansion of the airbag 15, so that the shielding net 3 and the cable 1 can be clamped and located at the center of the magnet 18. The energy of the interference signal is quasi-converted into thermal energy through the magnet 18. Compared with the state in which the cable 1 is offset in the magnet 18, the signal elimination efficiency can be improved. At the same time, the clamping of the airbag 15 avoids damage to the cable 1 compared to mechanical clamping, and ensures that the magnet 18 can exert the best signal suppression performance while ensuring the mechanical integrity of the wiring harness.

[0043] A support cup 20 is placed on the outer surface of the outer bellows 2 and is engaged with the outer bellows 2. An elastic plug-in card 21 is fixedly installed on the outer surface of one end of the support cup 20 and is engaged with the mounting hole inside the vehicle.

[0044] By supporting the support cup 20 and placing and engaging the outer corrugated tube 2, the elastic plug-in card 21 can be inserted into the mounting hole of the vehicle body and rotate along with the bending of the outer corrugated tube 2, so that the outer corrugated tube 2 can be adjusted at will, making the connection and installation of the outer corrugated tube 2 and the gathered cable 1 more convenient.

[0045] Binding holes 22 are formed on the outer surfaces of both ends of the support cup 20 , and cable ties 23 are inserted into the binding holes 22 , and the outer surfaces of the cable ties 23 are respectively in contact with the outer surfaces of the support cup 20 and the outer corrugated tube 2 .

[0046] After the cable tie 23 is passed through the binding hole 22, it can be firmly fixed to the outer surface of the support cup 20, and the support cup 20 and the outer corrugated tube 2 can be firmly fixed by the cable tie 23, reducing the chance of the cable tie 23 falling due to movement. At the same time, through the use of the cable tie 23 and the support cup 20, the support cup 20 can be arbitrarily fixed at different positions on the outer corrugated tube 2, so as to be flexibly installed and fixed.
