[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0025] Example 1

[0026] The present invention provides a method for producing a wire harness. As shown in FIG1 , the method includes: step S10, arranging a plurality of wire harness conductors 10; step S20, additively molding an insulator 20; gaps 11 are provided between the wire harness conductors 10, and the insulator 20 wraps the wire harness conductors 10 and fills the gaps 11.

[0027] In the production method of the wiring harness, a plurality of wiring harness conductors 10 are first arranged according to the electrical connection function to be achieved, and then an insulator 20 is formed by additive manufacturing to achieve insulation and fixation. The conductive loop can be connected to an external electrical device to achieve the electrical connection function of the wiring harness. The production method of the wiring harness has the following advantages: (1) It eliminates the step of extruding the insulation layer of the wire, shortens the wiring harness processing time, reduces the cost of raw materials, and reduces the cost of wiring harness wire production; (2) It can adapt to large-scale, automated production methods, improve production efficiency, and achieve rapid production; (3) The insulator 20 is uniformly set around the pre-arranged wiring harness conductors 10 to achieve uniform insulation, and the insulator 20 can be set quickly and conveniently; (4) The produced wiring harness is easy to install and connect with external electrical devices, reduces installation time, and saves space.

[0028] In one embodiment, step S10 and step S20 can be performed alternately multiple times, i.e., the wiring harness conductors 10 and the insulator 20 can be arranged and formed multiple times. In another embodiment, all the wiring harness conductors can be arranged at once, and then the insulator 20 can be formed, thereby improving production efficiency.

[0029] The terminal of the wiring harness conductor 10 can be connected to a gold finger, a crimping terminal, a welding terminal or a welding wire to facilitate connection with other electrical circuits.

[0030] In this wiring harness production method, the insulation coating and insulating varnish can be omitted from the wiring harness conductor 10, and a unified insulator 20 is formed through step S20. In some embodiments, referring to FIG. 4 , which is a partial schematic diagram of a wiring harness produced by this wiring harness production method, the wiring harness conductor 10 has a single-core structure, i.e., the wiring harness conductor 10 is a single wire. In some embodiments, referring to FIG. 5 , which is a partial schematic diagram of a wiring harness produced by this wiring harness production method, the wiring harness conductor 10 has a multi-core structure, i.e., the wiring harness conductor 10 includes multiple wires, preferably, the wires are flexible wires.

[0031] In one embodiment, the wiring harness production method includes step S01, performed before step S10. Step S01: preparing a molded housing 30 having a mold cavity 31; in step S10, placing the wiring harness conductor 10 in the mold cavity 31; and in step S20, molding the insulator 20 in the mold cavity 31. As shown in Figures 2 and 3, the molded housing 30 defines the shape and size of the insulator 20. Based on the requirements of the wiring harness to be produced, the molded housing 30 is prepared to conform to the orientation of the wiring harness conductor 10.

[0032] In one embodiment, the wire harness conductor 10 , the insulator 20 and the molded housing 30 form an integral structure, that is, the molded housing 30 is a part of the produced wire harness.

[0033] In another embodiment, the wire harness production method includes step S30 performed after step S20. Step S30: removing the insulator 20 and the wrapped wire harness conductor 10 from the mold cavity 31, and forming the housing 30 and its mold cavity 31 as a tool for producing the wire harness.

[0034] The molded housing 30 can adopt a contoured structure. The shape of the molded housing 30 is adapted to the installation environment. When the molded housing 30 is used as a tool, the insulator 20 of the molded wiring harness can be a contoured structure, which increases the application environment of the produced wiring harness, can adapt to different product structures, and is convenient for use on electrical devices with complex installation environments. When the molded housing 30 is used as a part of the produced wiring harness, the molded housing 30 can adapt to the application environment, which increases the application environment of the produced wiring harness, can adapt to different product structures, and is convenient for use on electrical devices with complex installation environments.

[0035] Furthermore, the molded housing 30 is a part of the produced wiring harness, and the molded housing 30 is a component of the electrical device, thus realizing the integrated production of components and wiring harness, which is beneficial to the rapid installation and removal of the wiring harness.

[0036] In one embodiment, in step S10, the plurality of wiring harness conductors 10 are disconnected from each other, and each wiring harness conductor 10 independently transmits current. In another embodiment, in step S10, at least two wiring harness conductors 10 are electrically connected using one or more of crimping, welding, 3D printing, laser sintering, or printed connection points. Multiple wiring harness conductors 10 within a wiring harness can implement relatively complex circuit functions.

[0037] In one embodiment, in step S10, the wiring harness conductors 10 may extend along a straight line or a curve. As shown in FIG2 , a plurality of wiring harness conductors 10 are distributed along the same plane.

[0038] In other embodiments, in step S10 , the plurality of harness conductors 10 are distributed and extended in space, for example, the harness extends along a spatial curve.

[0039] In one embodiment, step S10 adopts one or more of a 3D printing process, a laser powder sintering process, a metal injection molding process, a laser subtractive process, a conductive ink printing process or a printed circuit board process.

[0040] Specifically, the 3D printing process and the laser powder sintering process are both additive processes, which use metal powder or conductive material for melt printing, and the molding shell 30 can be used to support the molding. The metal injection molding process uses a mold to shape the metal in the mold, and then put it into the mold cavity 31. The laser subtractive process is to shape the sheet or foil-shaped metal material, and then cut off the unnecessary parts to leave the wiring harness conductor 10 part. The conductive ink printing process is to print conductive ink onto the substrate to form a conductive loop, and the conductive loop and the substrate together serve as the wiring harness conductor 10. The printed circuit board process uses the method of corroding the copper plate to obtain a conductive loop, and the conductive loop serves as the wiring harness conductor 10.

[0041] In another embodiment, in step S10, the wiring harness conductors 10 are arranged by laying. Wires can be used as the wiring harness conductors 10, and the selected wires can be free of insulation and varnish. Specifically, laying can be performed manually or by equipment.

[0042] This wire harness production method utilizes a wire feeder 40. In step S10, the wire harness conductor 10 is delivered into the mold cavity 31 by the wire feeder 40. The wire feeder 40 helps ensure the accuracy of the position of the wire harness conductor 10. The wire feeder 40 can spatially arrange the wire harness conductor 10 on the mold cavity 31 and the support sheet 32.

[0043] Furthermore, the wire feeding mechanism 40 includes a roller mechanism 41, and the roller mechanism 41 includes at least two rollers 42 arranged at intervals. As shown in Figure 6, the wire harness conductor 10 passes between the two rollers 42. When the roller 42 rotates, it relies on friction to drive the wire harness conductor 10 to translate into the mold cavity 31, thereby completing the arrangement of the wire harness conductor 10.

[0044] In one embodiment, a support sheet 32 ​​for supporting the wiring harness conductor 10 is provided in the mold cavity 31. The support sheet 32 ​​can prop up the wiring harness conductor 10 so that the insulator 20 surrounds the wiring harness conductor 10; the support sheet 32 ​​also plays a positioning role for the wiring harness conductor 10. A plurality of support sheets 32 can be provided in the mold cavity 31. The insulator 20 can form an integral structure with the support sheet 32, and the support sheet 32 ​​serves as part of the produced wiring harness. The support sheet 32 ​​is preferably made of an insulating material. More preferably, the support sheet 32 ​​and the insulator 20 are made of the same material. In step S20, the insulator 20 is overmolded on the outside of the wiring harness conductor 10, and the support sheet 32 ​​is integrated with the insulating layer to better ensure the insulation performance of the wiring harness.

[0045] In one embodiment, step S20 uses a 3D printing process, an injection molding process, a spraying process, or a dipping process to mold the insulator 20, and the insulator 20 is molded around the wiring harness conductor 10. Specifically, the 3D printing process is to melt the insulating material and then print it into the mold cavity 31. Injection molding is to use the injection mold as a molding shell 30, and to integrally inject the insulating material into the injection mold. The spraying process is to spray the insulating material onto the conductor to form an insulating layer. The dipping process is to immerse the mold cavity 31 and the conductor in the insulating material so that the insulating material can adhere to the conductor. Preferably, the molded shell 30 is used to mold the insulator 20. In some cases, such as when the insulator 20 adopts the dipping process, the molded shell 30 can be omitted.

[0046] Example 2

[0047] The present invention provides a wiring harness produced by the above-mentioned wiring harness production method. The wiring harness includes wiring harness conductors 10 and insulators 20 . Gaps 11 are provided between the wiring harness conductors 10 . The insulators 20 wrap the wiring harness conductors 10 and fill the gaps 11 .

[0048] In one embodiment, the wiring harness conductor 10, insulator 20, and molded housing 30 form an integrated structure. For some wiring harnesses with complex shapes, a unified insulation method can be used to fill the insulator 20 material. This can eliminate multiple steps in existing wiring harness processing, saving processing time, improving production efficiency, and reducing wiring harness costs. Because the insulator 20 material has a certain degree of adhesion, removing the molded housing is difficult. Therefore, when designing the wiring harness, the molded housing 30 can be directly incorporated into the wiring harness, forming an integrated structure, eliminating the need to remove the molded housing 30 from the insulator 20.

[0049] The molded housing 30 can adopt a contoured structure. The shape of the molded housing 30 is adapted to the installation environment. When the molded housing 30 is used as a tool, the insulator 20 of the molded wiring harness can be a contoured structure, which increases the application environment of the produced wiring harness, can adapt to different product structures, and is convenient for use on electrical devices with complex installation environments. When the molded housing 30 is used as a part of the produced wiring harness, the molded housing 30 can adapt to the application environment, which increases the application environment of the produced wiring harness, can adapt to different product structures, and is convenient for use on electrical devices with complex installation environments.

[0050] Furthermore, the molded housing 30 is a part of the produced wiring harness, and the molded housing 30 is a component of the electrical device, thus realizing the integrated production of components and wiring harness, which is beneficial to the rapid installation and removal of the wiring harness.

[0051] In one embodiment, multiple harness conductors 10 are disconnected from each other, and each harness conductor 10 independently transmits current. Alternatively, at least two harness conductors can be electrically connected using one or more methods such as crimping, welding, 3D printing, laser sintering, or printed connection points. Multiple harness conductors 10 within a harness can implement relatively complex circuit functions.

[0052] In one embodiment, the wiring harness conductor extends along a straight line or a curve. As shown in FIG2 , multiple wiring harness conductors 10 are distributed along the same plane. When the wiring harness is connected to fewer electrical devices, the two ends of the wiring harness are connected to different electrical devices, and the wiring harness conductors will extend along the assembly route.

[0053] In one embodiment, multiple wiring harness conductors are distributed along the same plane, or multiple wiring harness conductors are distributed and extended in space. Complex wiring harnesses have multiple branching structures and are used to connect many different electrical devices. Currently, electrical devices often have large flat or curved structures. The complex wiring harness can be placed directly on the electrical devices, which also facilitates the pouring of the insulator 20.

[0054] In one embodiment, a support sheet 32 ​​is provided in the insulator. The support sheet 32 ​​includes side surfaces and a peripheral surface. The side surfaces and at least the peripheral surface are connected to the insulator 20, and the wiring harness conductors 10 pass through the side surfaces or contact the peripheral surface. During the arrangement of the wiring harness conductors 10, some wiring harness conductors 10 are longer and have lower hardness, which can cause the middle wiring harness conductors 10 to sag and contact the molded shell 30. When the insulator 20 is filled, the wiring harness conductors 10 are not isolated from the molded shell 30, resulting in a short circuit of the wiring harness conductors 10, causing damage to the wiring harness and even a safety accident. Therefore, in step S02, which is performed before step S10, a support sheet for supporting the wiring harness conductors 10 is provided in the mold cavity to ensure that the filled insulator 20 can isolate the wiring harness conductors 10 from the molded shell 30. In addition, when there are multiple wiring harness conductors 10, the use of the support sheet 32 ​​to separate the multiple wiring harness conductors 10 can enable the insulator 20 to fully isolate the multiple wiring harness conductors 10, ensuring the accuracy of the wiring harness loop.

[0055] The support sheet 32 ​​also serves to position the wiring harness conductor 10. Multiple support sheets 32 may be positioned within the mold cavity 31. The insulator 20 and the support sheet 32 ​​may form an integral structure, with the support sheet 32 ​​serving as part of the produced wiring harness. The support sheet 32 ​​is preferably made of an insulating material, and more preferably, the support sheet 32 ​​and the insulator 20 are made of the same material. In step S20, the insulator 20 is overmolded over the wiring harness conductor 10, and the support sheet 32 ​​is integrated with the insulation layer to better ensure the insulation performance of the wiring harness.

[0056] In one embodiment, the insulator 20 is made of one or more materials selected from the group consisting of polyvinyl chloride, polyurethane, nylon, polypropylene, silicone rubber, cross-linked polyolefin, synthetic rubber, polyurethane elastomer, cross-linked polyethylene, and polyethylene.

[0057] In one embodiment, the wire harness conductor 10 is made of a metal material, which is one or more of nickel or its alloys, cadmium or its alloys, zirconium or its alloys, chromium or its alloys, cobalt or its alloys, manganese or its alloys, aluminum or its alloys, tin or its alloys, titanium or its alloys, zinc or its alloys, copper or its alloys, silver or its alloys, and gold or its alloys. The most commonly used metal material for conductors is copper or copper alloys, as copper has relatively good electrical conductivity among metals, is not a precious metal, is relatively easy to process, and has good ductility. However, as copper prices continue to rise, the material cost of using copper as a conductor will become increasingly high. Therefore, people have begun to seek alternatives to copper to reduce costs. Aluminum accounts for approximately 7.73% of the Earth's crust. After optimizing its extraction technology, its price is relatively low. Furthermore, aluminum is lighter than copper and has a conductivity second only to copper. Therefore, aluminum or its alloys can partially replace copper or its alloys in electrical connections.

[0058] In one embodiment, the material of the wiring harness conductor 10 includes non-metallic materials, and the non-metallic materials are one or more combinations of conductive ceramics, carbon-containing conductors, solid electrolytes, mixed conductors, and conductive polymer materials.

[0059] In one embodiment, the carbon-containing conductor is graphite powder, carbon nanotube material, graphene material, or a combination thereof.

[0060] In one embodiment, the cross-sectional area of ​​the harness conductor 10 is 0.1 mm 2 -260mm 2 In the wiring harness, the cross-sectional area of ​​the wiring harness conductor 10 determines the current that the wiring harness conductor 10 can conduct. Generally, the wiring harness conductor 10 that realizes signal conduction has a smaller current and a smaller cross-sectional area. For example, the minimum cross-sectional area of ​​the signal line wiring harness conductor 10 of the automobile wiring harness can reach 0.1mm 2 , and the harness conductor 10 that realizes power conduction has a large current and a large cross-sectional area. For example, in a car battery harness, the maximum cross-sectional area of ​​the harness conductor 10 is 260mm 2 For wire harness conductors 10 with a smaller cross-sectional area, the wire harness conductors 10 can be arranged by using a wire feeding mechanism. For wire harness conductors 10 with a larger cross-sectional area, 3D printing of the wire harness conductors 10 or directly laying of the formed conductors 2 can be used.

[0061] In one embodiment, the insulator 20 is made of one or more of polyvinyl chloride, polyurethane, nylon, polypropylene, silicone rubber, cross-linked polyolefin, synthetic rubber, polyurethane elastomer, cross-linked polyethylene, and polyethylene.

[0062] In one embodiment, the breakdown strength of the insulator 20 is 0.3KV / mm-35KV / mm. Breakdown strength is also called dielectric breakdown strength. It indicates the highest electric field strength that a material can withstand to avoid being destroyed (broken down) under the action of an electric field. When the breakdown strength of the insulator 20 is lower than 0.3KV / mm, some thinner insulators 20 may be broken down under normal voltage, resulting in insulation failure. When the breakdown strength of the insulator 20 is higher than 35KV / mm, since high voltages higher than 35KV will not occur in general vehicle environments, the use of materials with too high a breakdown strength will increase the cost of the integrated wiring harness assembly, resulting in design waste.

[0063] In one embodiment, the thickness of the insulator 20 is 0.03mm-5mm. If the thickness of the insulator 20 is less than 0.03mm, not only can the breakdown voltage of the insulator 20 not be guaranteed to be higher than the operating voltage, but the wear resistance of the insulator 20 cannot be guaranteed. After repeated scraping, the insulator 20 will be damaged, exposing the wiring harness conductor 10, which will lead to leakage or short circuit, causing line damage and functional failure. When the thickness of the insulator 20 is equal to 5mm, the breakdown voltage, insulation resistance and wear resistance of the insulator 20 can all meet the requirements. However, when the thickness is greater than 5mm, the thickness of the insulator 20 is relatively large, and problems such as pores and collapse may occur during the processing, which reduces the performance of the insulator 20. In addition, it also wastes the insulation layer material and increases the processing steps and time. Therefore, the inventors selected the thickness of the insulator 20 to be 0.03mm-5mm.

[0064] The wiring harness can adapt to large-scale, automated production methods, improve production efficiency, and achieve rapid production; and achieve unified insulation, and can conveniently and quickly set the insulator 20; the wiring harness is easy to install and connect with external electrical components, reduces installation time, saves space, eliminates the step of extruding the insulation layer of the wire, shortens the wiring harness processing time, and reduces the cost of raw materials and wiring harness production.

[0065] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
