[0002] Currently, with the continuous development of the new energy vehicle industry, automotive electrical and other control systems are also becoming increasingly sophisticated, complex, and diversified. However, the widely used wiring harnesses still rely on ordinary wires with plastic insulation layers.

[0031] The technical solutions in the embodiments of this article will be clearly and completely described below with reference to the accompanying drawings.

[0032] This article discloses an integral wire harness structure, such as Figures 1-5 As shown, it includes: at least one integrally formed substrate 1 laid along the shape of the installation environment, at least one flat conductor 2 mounted on the substrate 1, the flat conductor 2 extending along the length direction of the substrate 1, and at least one external conductive device 3, the external conductive device 3 being electrically connected to any of the flat conductor 2. The base 1 is provided with at least one support portion 11 along its length. The support portion 11 has two opposing sidewalls. At least one sidewall of the support portion 11 is provided with n stacked snap-fit ​​plates 12, where n≥2. A matching snap-fit ​​mechanism is provided between any adjacent snap-fit ​​plates 12 and at least part of the flat conductor 2. The flat conductor 2 is detachably snapped to the corresponding snap-fit ​​plate 12 through the snap-fit ​​mechanism. The base 1 in the overall wiring harness structure is integrally formed, which is simple in process. The base 1 can be laid in the in-vehicle installation environment, which is highly practical. At least one flat conductor 2 is installed on the base 1 and extends along the length of the base 1. The flat conductor 2 is snapped to the base 1 by the snap-fit ​​plates 12 and snap-fit ​​mechanism provided on the base 1. The flat conductor 2 can be set according to different circuit requirements, which is highly versatile. In addition, it also includes an external conductive device 3 that can be electrically connected to any flat conductor 2, so that the overall wiring harness structure can be applied to multiple usage environments.

[0033] In some embodiments, the n snap-fit ​​plates 12 disposed on each of the sidewalls are parallel to each other, and the snap-fit ​​mechanism includes a plurality of pressure arms 13 disposed on one of two adjacent snap-fit ​​plates 12 and a plurality of protrusions 14 disposed on the other. For example... Figure 1 As shown, n snap-fit ​​plates 12 are provided on the side wall of each support part 11 and are parallel to each other. The figure shows the case where the snap-fit ​​plates 12 are parallel to each other and are perpendicular to the side wall. The snap-fit ​​structure includes a pressure arm 13 and a boss 14, which are respectively provided on one of the two adjacent snap-fit ​​plates 12. The flat conductor 2 is fixedly installed by the snap-fit ​​mechanism.

[0034] In some embodiments, the pressure arm 13 is parallel to the snap-fit ​​plate 12. The fixed end 131 of the pressure arm 13 is integrally formed with the surface of the snap-fit ​​plate 12, and the free end 132 of the pressure arm 13 is provided with a predetermined distance from the surface of the snap-fit ​​plate 12 on which the pressure arm 13 is disposed. One end of the pressure arm 13 is fixed to the snap-fit ​​plate 12 to form a fixed end 131, and the fixed end 131 is integrally formed with the surface of the snap-fit ​​plate 12. The other end of the pressure arm 13 is a free end 132, and the free end 132 is provided with a predetermined distance from the surface of the snap-fit ​​plate 12 on which the pressure arm 13 is disposed, ensuring that the free end 132 can reciprocate relative to the snap-fit ​​plate 12, which facilitates the insertion and fixing of the flat conductor 2 between the snap-fit ​​plates 12.

[0035] In some embodiments, the distance between the highest point of the pressure arm 13 and the surface of the adjacent snap-fit ​​plate 12 is no greater than the thickness of the flat conductor 2. For example... Figure 1 As shown, in order to ensure that the flat conductor 2 can be inserted between two adjacent snap-fit ​​plates 12, the distance between the highest point of the pressure arm 13 and the surface of the adjacent snap-fit ​​plate 12 is set to be no greater than the thickness of the flat conductor 2. If the distance is greater than the thickness of the flat conductor 2, the flat conductor 2 may move between the two adjacent snap-fit ​​plates 12, weakening the fixing effect.

[0036] In some embodiments, the fixed end 131 of the pressure arm 13 is located away from the support portion 11, and the fixed end 131 forms a predetermined angle with the snap-fit ​​plate 12. For example... Figure 1 As shown, the fixed end 131 is disposed away from the support part 11, and the fixed end 131 forms a predetermined angle with the snap-fit ​​plate 12 to form a guide angle, so that the flat conductor 2 can be inserted between the snap-fit ​​plates 12 from the guide angle.

[0037] In some embodiments, the snap-fit ​​mechanism further includes a positioning hole 21 at least partially provided on the flat conductor 2, the positioning hole 21 being positioned corresponding to the position of the boss 14, the boss 14 engaging with the positioning hole 21 to prevent movement of the flat conductor 2. Figure 3 As shown, the snap-fit ​​mechanism also includes a positioning hole 21 provided on at least part of the flat conductor 2. The positioning hole 21 is positioned corresponding to the boss 14. The boss 14 and the positioning hole 21 cooperate with each other to restrict the movement of the flat conductor 2 relative to the substrate 1.

[0038] In some embodiments, the boss 14 has a chamfer on the side away from the support portion 11 to facilitate the insertion of the flat conductor 2. For example... Figure 1 As shown, the boss 14 has a chamfer on the side away from the support 11, which facilitates the flat conductor 2 to be inserted into the base 1 from the chamfer.

[0039] In some embodiments, the external conductive device 3 is a connector, which includes terminals. The terminals are directly electrically connected to the flat conductor 2 or electrically connected via wire 31. The overall wiring harness structure also includes the external conductive device 3, which is generally a connector. The connector includes terminals that are electrically connected to the corresponding flat conductor 2. The terminals can be directly electrically connected to the flat conductor 2. In other installation scenarios, if the distance between the connector and the corresponding flat conductor 2 is too large, the terminals and the flat conductor 2 can be electrically connected via wire 31.

[0040] In some embodiments, the flat conductor 2 is provided with a welding portion 22, and the terminal or the wire 31 is connected to the welding portion 22 by one of ultrasonic welding, resistance welding, friction welding, arc welding, laser welding, electron beam welding, pressure diffusion welding or magnetic induction welding.

[0041] Resistance welding is a method of welding that uses a strong current to pass through the contact point between the electrode and the workpiece, generating heat through contact resistance.

[0042] Friction welding is a method that uses the heat generated by friction between the contact surfaces of workpieces as a heat source to cause plastic deformation of the workpieces under pressure, thereby performing welding.

[0043] Ultrasonic welding uses high-frequency vibration waves to be transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other, forming a fusion between molecular layers.

[0044] Arc welding refers to the use of an electric arc as a heat source, utilizing the physical phenomenon of air discharge to convert electrical energy into the heat and mechanical energy required for welding, thereby achieving the purpose of joining metals. The main methods include shielded metal arc welding, submerged arc welding, and gas shielded welding.

[0045] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source.

[0046] Friction welding is a method that uses the heat generated by friction between the contact surfaces of workpieces as a heat source to cause plastic deformation of the workpieces under pressure, thereby performing welding.

[0047] Electron beam welding refers to the welding process that uses an accelerated and focused electron beam to bombard a welding surface placed in a vacuum or non-vacuum environment, causing the workpiece to melt and thus achieving welding.

[0048] Pressure welding is a method of welding that applies pressure to the workpieces, causing the joint surfaces to come into close contact and produce a certain amount of plastic deformation.

[0049] Magnetic induction welding involves two workpieces being subjected to a strong pulsed magnetic field, resulting in a high-speed instantaneous collision. Under the influence of a high pressure wave, the atoms of the two materials meet within the interatomic distance, thus forming a stable metallurgical bond at the interface. It is a type of solid-state cold welding that can weld conductive metals with similar or dissimilar properties together.

[0050] In some embodiments, a connecting wire is also included, with both ends of the connecting wire electrically connected to any two of the flat conductors 2. In specific application scenarios, depending on the needs of different current loops, any two flat conductors 2 may be electrically connected. In this case, a connecting wire is required. The connecting wire is made of conductive material, and its two ends are connected to any two flat conductors 2 to achieve electrical connection between the two flat conductors 2.

[0051] In some embodiments, multiple connecting lines are included, one end of each connecting line being electrically connected to any of the flat conductors 2, and the other ends being connected together. Specifically, when installing the flat conductors 2, depending on circuit requirements, multiple connecting lines are also included, one end of each connecting line being electrically connected to any of the flat conductors 2, and the other ends being connected together, thus electrically connecting any number of flat conductors 2 and increasing the current carrying capacity of the circuit.

[0052] In some embodiments, a housing 4 and a cover 5 are also included, such as Figure 2 As shown, the assembled substrate 1 and the flat conductor 2 are disposed inside the housing 4, and the cover 5 is interlocked with the housing 4. The assembled substrate 1 and flat conductor 2, placed within the housing 4, with the cover 5 interlocked with the housing 4, not only protect the circuit but also utilize the housing 4 to install the overall wiring harness structure within the vehicle body, extending its service life. In some applications, the surfaces of the substrate 1 that contact the housing 4 or cover 5 are provided with positioning protrusions 14, and the corresponding surfaces of the cover 5 or housing 4 are provided with grooves to accommodate the positioning protrusions 14, thus limiting the relative position of the substrate 1 and the housing 4 or cover 5.

[0053] In some embodiments, a flexible flat cable 8 is provided between the base 1 and the housing 4 or the cover 5. In actual use, in addition to using the overall wiring harness structure to transmit current, it may also be necessary to transmit signal information. Therefore, a flexible flat cable 8 can be laid between the base 1 and the housing 4 or the cover 5 for transmitting signal information.

[0054] In some embodiments, bolts 6 and nuts 7 are also included. The support portion 11 has bolt holes 111 in a direction perpendicular to its sidewall. The bolts 6 and nuts 7 assemble and connect the cover 5, the support portion 11, and the housing 4. Figure 1 and Figure 2As shown, the support part 11 is provided with bolt holes 111. The bolt holes 111 are perpendicular to the side wall of the support part 11 and pass through the support part 11. The bolt 6 passes through the bolt holes 111 and cooperates with the nut 7 to assemble and connect the cover 5, the support part 11 and the shell 4.

[0055] In some embodiments, one of the housing 4 and the cover 5 is provided with a snap-fit ​​groove, and the other is provided with a snap-fit ​​protrusion 41, to fasten the housing 4 and the cover 5 together. The snap-fit ​​groove on one of the housing 4 and the snap-fit ​​protrusion 41, and the engagement of the snap-fit ​​groove and the snap-fit ​​protrusion 41, prevent relative movement between the housing 4 and the cover 5, ensuring the stability of the fastening between them.

[0056] In some embodiments, the substrate 1 is made of an insulating material, and the flat conductor 2 is made of aluminum or an aluminum alloy. The flat conductor 2 is generally made of aluminum or an aluminum alloy, as aluminum or aluminum alloys are lightweight and low-cost, making them commonly used conductors in automotive wiring harnesses. The overall wiring harness structure described herein allows for better application of aluminum or aluminum alloys as conductors in the wiring harness.

[0057] In some embodiments, a plurality of said substrates 1 are included, and the extension direction of at least one said substrate 1 is different from the extension direction of the other said substrates 1. According to a predetermined circuit layout, a plurality of substrates 1 may be included, and the extension direction of at least one substrate 1 is different from the extension direction of the other substrates 1, and a plurality of flat conductors 2 are respectively snapped into the plurality of substrates 1 to form a current loop.

[0058] In some embodiments, the ratio of the distance between adjacent snap-fit ​​plates 12 to the thickness of the flat conductor 2 is 1:0.5 to 1:0.95. When the ratio is large, the heat dissipation effect of the substrate 1 is better, reducing the risk of damage to the overall wiring harness structure due to increased operating temperature caused by poor heat dissipation. However, if the distance between adjacent snap-fit ​​plates 12 is too large, the overall wiring harness structure will be too large, occupying too much space in the vehicle. Therefore, after multiple experiments and improvements, the inventors determined that a ratio of 1:0.5 to 1:0.95 can ensure that the overall wiring harness structure volume is within a reasonable range, does not occupy too much space in the vehicle, and also ensures heat dissipation and reduces risk.

[0059] In some embodiments, multiple snap-fit ​​plates 12 are provided along the length of the substrate, and the width of each snap-fit ​​plate 12 is not less than the width of the flat conductor 2. In actual use, the snap-fit ​​plates 12 may not be provided as a whole along the length of the substrate 1, but multiple snap-fit ​​plates 12 may be provided separately for each layer. In this case, the width of the snap-fit ​​plate 12 needs to be set to be greater than or equal to the width of the flat conductor 2 in order to ensure the supporting force of the snap-fit ​​plate 12 on the flat conductor 2 and prevent the snap-fit ​​plate from being deformed due to excessive force.

[0060] In some embodiments, the distance between adjacent snap-fit ​​plates 12 along the length of the substrate 1 is less than or equal to five times the width of the flat conductor 2. When multiple snap-fit ​​plates 12 are provided along the length of the substrate 1, the distance between adjacent snap-fit ​​plates 12 along the length of the substrate 1 is less than or equal to five times the width of the flat conductor 2. If this distance is too large, it cannot effectively support the flat conductor, and the flexible flat conductor may detach from the adjacent snap-fit ​​plates 12 and come into contact with flat conductors of different layers. Therefore, the distance is set to be less than or equal to five times the width of the flat conductor 2 to avoid short circuits or failures caused by conductors of different layers coming into contact with each other, which would affect the circuit layout inside the vehicle.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this document. The scope of this document is defined by the appended claims.
