[0003] As the electrical functions of transportation vehicles such as automobiles, trains, and steamships become increasingly complex, the corresponding circuits are also increasing, and the wiring harness circuits connecting each electrical device to the power source are also increasing. As a result, wiring harnesses are becoming increasingly large and complex. For example, the main wiring harness of a C-level vehicle body typically has approximately 800 to 1,000 circuits assembled into a single broad wiring harness, distributed throughout the body. If any part of the wiring harness is damaged, the entire wiring harness must be replaced. Meanwhile, due to custom manufacturing and other factors, wiring harness circuits and branch circuits are becoming increasingly flexible, and simultaneous production of different models of wiring harnesses is required. This makes mass production unfeasible, requiring extensive specialized equipment and work uniforms, and requires workers with advanced skills and wiring harness inspection capabilities.

BEST MODE FOR CARRYING OUT THE INVENTION

[0009] To facilitate a clearer understanding of the technical features, objectives, and effects of the present application, specific embodiments of the present application will be described with reference to the drawings. However, the terms "first," "second," etc., are for illustrative purposes only and do not imply or suggest relative importance or the number of technical features. A feature qualified by "first," "second," etc., may explicitly or implicitly include one or more corresponding features. In the description of the present application, unless otherwise specified, "multiple" means two or more. In the description of this specification, unless otherwise specified, the term "connected" should be understood in a broad sense. For example, a connection may be fixedly connected, detachably connected, directly connected, or connected via an intermediate medium. Therefore, those skilled in the art should understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0010] As shown in Figures 1 and 3, according to an embodiment of one aspect of the present application, a wiring harness module 100 is provided, which includes a conductor portion 110 and an insulating portion 120 that seals the conductor portion 110, and the conductor portion 110 includes at least one conductor 111, each of which is connected to at least one input conductive contact 130 and at least one output conductive contact 140, and which electrically connects the conductors 111 of different wiring harness modules 100 by connecting the input conductive contacts 130 and the output conductive contacts 140 of the different wiring harness modules 100.

[0011] The wiring harness modules of the present application are intended to be assembled into a wiring harness, with each conductor 111 of each wiring harness module 100 being connected to at least one input conductive contact 130 and at least one output conductive contact 140, thereby connecting each wiring harness module to at least two other wiring harness modules, and each conductor being electrically connected to at least two other conductors, allowing assembly into complex conductive circuits.

[0012] As shown in Figures 2, 3 and 5, when assembling a wiring harness, the conductors of multiple wiring harness modules are connected via input conductive contacts 130 and output conductive contacts 140 according to the required wiring harness conductive circuit (see Figure 3). This assembly method is flexible and easy to install and remove. During maintenance, only the damaged wiring harness module needs to be removed, eliminating the need to replace the entire wiring harness or entire group, thereby saving manufacturing and maintenance costs.

[0013] Taking the assembly of three wiring harness modules 100 as an example, the three wiring harness modules 100 are respectively a first wiring harness module, a second wiring harness module, and a third wiring harness module. When assembled, the output conductive contacts 140 of the first wiring harness module are connected to the input conductive contacts 130 of the second wiring harness module, and the output conductive contacts 140 of the second wiring harness module are connected to the input conductive contacts 130 of the third wiring harness module, so that the three wiring harness modules 100 can be electrically connected in sequence.

[0014] The wiring harness module of the present application can be mass-produced, automated, and customized, which can increase production rate and improve yield.

[0015] Furthermore, the cross-sectional area of ​​the conductor 111 is 0.1 mm 2 -260mm 2 In a wiring harness, the current flowing through the conductor 111 is determined by the cross-sectional area of ​​the conductor 111. Generally, the current of a conductor 111 capable of communication is small, and the cross-sectional area of ​​the conductor 111 is also small. For example, the minimum cross-sectional area of ​​a signaling line conductor 111 in an automobile wiring harness is 0.1 mm. 2 When the power supply is turned on, the current of the conductor 111 is large and the cross-sectional area of ​​the conductor 111 is also large. For example, in the case of an automobile battery wiring harness, the maximum cross-sectional area of ​​the conductor 111 is 260 mm 2 When the cross-sectional area of ​​the conductor 111 is small, the conductor 111 can be arranged by laying it using a wire feeder, and when the cross-sectional area of ​​the conductor 111 is large, the conductor 111 can be printed in three dimensions or the molded conductor 111 can be directly laid.

[0016] Furthermore, the material of the insulating portion 120 is one or more of polyvinyl chloride, polyurethane, nylon, polypropylene, silicone rubber, cross-linked polyolefin, synthetic rubber, polyurethane elastomer, cross-linked polyethylene, and polyethylene.

[0017] Furthermore, the breakdown strength of the insulating portion 120 is 0.3 KV / mm to 35 KV / mm. Breakdown strength is also called dielectric breakdown strength. It refers to the maximum electric field strength that a material can withstand to prevent it from bursting (destroying) under the action of an electric field. If the breakdown strength of the insulating portion 120 is less than 0.3 KV / mm, parts of the thin insulating portion 120 will break down under typical voltages, rendering the insulation ineffective. If the breakdown strength of the insulating portion 120 exceeds 35 KV / mm, high voltages exceeding 35 KV will not occur in a typical automotive environment. Using a material with too high a breakdown strength will increase the cost of the integrated wiring harness module and result in design waste.

[0018] The thickness of the insulating part 120 may be between 0.03 mm and 5 mm. If the thickness of the insulating part 120 is less than 0.03 mm, not only will the breakdown voltage of the insulating part 120 not be guaranteed to be higher than the operating voltage, but the wear resistance of the insulating part 120 will also be insufficient. Repeated scraping may damage the insulating part 120, exposing the conductor 111 and potentially causing leakage or short circuits, resulting in circuit breakdown and loss of functionality. If the thickness of the insulating part 120 is 5 mm, the breakdown voltage, insulation resistance, and wear resistance of the insulating part 120 will all meet the requirements. However, if the thickness exceeds 5 mm, the insulating part 120 will be too thick, resulting in problems such as pores and depressions during processing, which will reduce the functionality of the insulating part 120, waste material, and increase the processing time. Therefore, the thickness of the insulating part 120 is formed to be between 0.03 mm and 5 mm.

[0019] As shown in Figures 1 to 3, in one embodiment, the conductor portion 110 includes a plurality of conductors 111 insulated from one another, and each conductor 111 is connected to at least one input conductive contact 130 and at least one output conductive contact 140, respectively. That is, each wiring harness module 100 has a plurality of conductors 111 insulated from one another, and each conductor 111 transmits a different current and signal to send command information to electrical equipment, making it easy to assemble into a complex wiring harness. When assembling into a complex wiring harness, the number of wiring harness modules 100 to be connected in a row can be reduced, the volume of the complex wiring harness can be reduced, the structure of the complex wiring harness can be simplified, and the cost of the wiring harness can be further reduced.

[0020] In one embodiment, each conductor 111 of the conductor portion 110 may be formed as an integrated structure, or may be formed as a separate structure in which multiple conductor portions are connected, and the multiple conductor portions may be connected to each other with terminals (see Figure 15), or by welding (see Figure 16), or by drilling holes in the insulating portion 120 and injecting a conductive material into the holes (see Figure 17).

[0021] In one embodiment, the conductor portion 110 includes a connection segment 112, and at least two conductors 111 are electrically connected via the connection segment 112. When two or more conductors are to turn on current or signals of the same circuit, these conductors 111 should be electrically connected. As shown in Figures 13 and 17, by attaching the connection segment 112, the conductors 111 can be electrically connected, reducing the number of circuits in the electrical equipment and optimizing the electrical layout, thereby reducing the volume of the wiring harness.

[0022] Furthermore, the connection segments 112 may be realized by crimping or welding and may be connected to both ends or the middle portion of the conductor 111 .

[0023] In one embodiment, each conductor 111 has one or more input contacts, each input contact connected to an input conductive contact 130, and each conductor 111 has one or more output contacts, each output contact connected to an output conductive contact 140.

[0024] Referring to FIG. 13, in a first possible technical solution, each conductor 111 has a plurality of input contacts and one output contact, and the plurality of input contacts are each connected to one input conductive contact 130, that is, each conductor 111 is connected to a plurality of input conductive contacts 130 and one output conductive contact 140, and when the plurality of input conductive contacts 130 are each electrically connected to a plurality of other conductors, a parallel circuit connection is realized.

[0025] Referring to FIG. 13, in a second possible technical solution, each conductor 111 has one input contact and multiple output contacts, and the multiple output contacts are each connected to one output conductive contact 140, that is, each conductor 111 is connected to one input conductive contact 130 and multiple output conductive contacts 140, and the multiple power conductive contacts 140 are each electrically connected to multiple other conductors, thereby realizing a parallel circuit connection.

[0026] Referring to FIG. 13, in a third possible technical solution, each conductor 111 has a plurality of input contacts and a plurality of output contacts, and the plurality of input contacts are each connected to one input conductive contact 130, and the plurality of output contacts are each connected to one output conductive contact 140; that is, each conductor 111 is connected to a plurality of input conductive contacts 130 and a plurality of output conductive contacts 140, and the plurality of input conductive contacts 130 are each electrically connected to a plurality of other conductors, and the plurality of output conductive contacts 140 are each electrically connected to a plurality of other conductors, thereby realizing a parallel circuit connection.

[0027] 14 , in another embodiment, the input conductive contacts 130 and the output conductive contacts 140 are butt joints 103 protruding from the insulating portion 120, and the butt joints 103 of different wiring harness modules 100 are overlapped, connected, and fixed to electrically connect the conductors 111 of the different wiring harness modules 100. For example, the butt joints 103 of different wiring harness modules 100 are detachably connected to each other by bolts.

[0028] As shown in Figures 7 and 14, in one embodiment, at least one of the input conductive contacts 130 and the output conductive contacts 140 protrudes into the insulating portion 120 so that the input conductive contacts 130 and the output conductive contacts 140 of different wiring harness modules 100 can be easily connected.

[0029] As shown in Figures 7 to 13, in a specific embodiment, one of the input conductive contacts 130 and the output conductive contacts 140 is a male terminal plug 101 protruding from the insulating portion 120, and the other is a female terminal socket 102 recessed within the insulating portion 120. By plugging in and connecting the male terminal plugs 101 and female terminal sockets 102 of different wiring harness modules (see Figure 8), the conductors 111 of different wiring harness modules 100 are electrically connected, thereby simplifying the structure and making the connection operation easier.

[0030] To facilitate the insertion and connection of male terminal plug 101 and female terminal socket 102, an outwardly extending guide inclined surface is provided at the end of male terminal plug 101 (see FIG. 9).

[0031] Here, the male terminal plug 101 and the female terminal socket 102 are matched in shape, and the cross section of both is formed to be square (see FIG. 10) or circular (see FIG. 11).

[0032] In one embodiment, a coating layer is formed on at least a portion of the male terminal plug 101 and the female terminal socket 102 to improve corrosion resistance and conductivity, increase the number of connections, and extend the service life of the male terminal plug 101 and the female terminal socket 102.

[0033] The coating layer is applied to the male terminal plug 101 and the female terminal socket 102 by a method such as electroplating, chemical plating, magnetron sputtering or vacuum plating.

[0034] Electroplating is a process that uses the principle of electrolysis to thinly plate the surface of some metals with another metal or alloy.

[0035] Chemical plating refers to the process of forming a metal immersion through a controllable oxidation-reduction reaction under the catalysis of the metal.

[0036] Magnetron sputtering is a method that uses the interaction of magnetic and electric fields to make electrons move in a spiral pattern near the target surface, increasing the probability that the electrons will collide with argon and generate ions. The generated ions collide with the target surface under the influence of the electric field, sputtering the target material.

[0037] Vacuum plating refers to the process of immersing various metal or non-metal thin films on the surface of plastic parts under vacuum conditions by distillation, sputtering, etc.

[0038] The coating layer material may be one or more of gold, silver, nickel, tin, zinc, tin-lead alloy, silver-antimony alloy, palladium, palladium-nickel alloy, graphite-silver, graphene-silver, and silver-gold-zirconium alloy. Copper is an active metal that undergoes oxidation with oxygen and water during use. Therefore, forming one or more inert metals as a coating layer can extend the service life of the male terminal plug 101 and female terminal socket 102. Furthermore, for male terminal plugs 101 and female terminal sockets 102 that are frequently inserted and extracted, a good wear-resistant metal must be formed as a coating layer, which can significantly increase the service life of the male terminal plug 101 and female terminal socket 102. The male terminal plug 101 and female terminal socket 102 require good electrical conductivity. The conductivity and stability of these metals are superior to that of copper or copper alloys, allowing the male terminal plug 101 and female terminal socket 102 to maintain better electrical performance and service life.

[0039] In order to demonstrate the effect of different coating layer materials on the overall performance of the male terminal plug 101 and female terminal socket 102, the inventors used the same specifications and materials to conduct a series of insertion / extraction cycles and corrosion resistance time tests using samples of male terminal plug 101 and female terminal socket 102 with different coating layer materials, and to demonstrate the advantages and disadvantages of the selected materials and other common plating materials, the inventors used tin, nickel, and zinc as the coating layer materials in the experiments. The experimental results are shown in Table 1 below.

[0040] The insertion / extraction counts in Table 1 below were obtained by the following method. The male terminal plug 101 and the female terminal socket 102 were fixed to an experimental stage, and a mechanical device was used to simulate the insertion / extraction of the male terminal plug 101 and the female terminal socket 102. The experiment was stopped every 100 insertions / extractions to observe whether the surface coating layer of the male terminal plug 101 and the female terminal socket 102 had been ruptured. If the surface coating layer was damaged and the material of the male terminal plug 101 or the female terminal socket 102 itself was exposed, the experiment was stopped and the insertion / extraction count was recorded at that point. An insertion / extraction count of 8,000 or less was deemed to be unacceptable.

[0041] The corrosion resistance time test in Table 1 below was conducted as follows: The male terminal plug 101 and female terminal socket 102 were placed in a salt spray test chamber, and salt water was sprayed at each position on the male terminal plug 101 and female terminal socket 102. They were removed every 20 hours and the surface corrosion was observed. This constitutes one cycle. When the corroded area on the surface of the male terminal plug 101 and female terminal socket 102 exceeded 10% of the total area, the test was stopped and the number of cycles was recorded. In this example, a test with fewer than 80 cycles was deemed to have failed.

[0042] [Table 1]

[0043] Referring to the above table, it can be seen that when gold, silver, silver-antimony alloy, palladium, palladium-nickel alloy, graphite-silver, graphene-silver, and silver-gold-zirconium alloy are used as coating layer materials, the experimental results far exceed the standard values ​​and the performance is relatively stable. Even when nickel, tin, tin-lead alloy, and zinc are used as coating layer materials, the experimental results meet the requirements. Therefore, the inventors used one or more combinations of gold, silver, nickel, tin, tin-lead alloy, zinc, silver-antimony alloy, palladium, palladium-nickel alloy, graphite-silver, graphene-silver, and silver-gold-zirconium alloy as coating layer materials.

[0044] In one embodiment, the coating layer includes a base layer and a surface layer, and the coating layer is formed using a multi-layer plating method. After processing, the male terminal plug 101 and the female terminal socket 102 will have many slots and holes under the surface micro-interface, and these slots and holes are the biggest cause of wear and corrosion of the male terminal plug 101 and the female terminal socket 102 during use. Therefore, a base layer is coated on the surface of the male terminal plug 101 and the female terminal socket 102 to fill the slots and holes on the surface, so that the surfaces of the male terminal plug 101 and the female terminal socket 102 are flat and free of holes. When the surface coating layer is then coated, they can be assembled more firmly and have a flatter surface. Since there are no slots or holes on the surface of the coating layer, the male terminal plug 101 and the female terminal socket 102 have better wear resistance, corrosion resistance and electrical performance, and the service life of the male terminal plug 101 and the female terminal socket 102 can be greatly increased.

[0045] In one embodiment, the material of the base layer is one or more of gold, silver, nickel, tin, tin-lead alloy, and zinc, and the material of the surface layer is one or more of gold, silver, nickel, tin, tin-lead alloy, silver-antimony alloy, palladium, palladium-nickel alloy, graphite-silver, graphene-silver, and silver-gold-zirconium alloy.

[0046] In another embodiment, the base layer has a thickness of 0.01 μm-15 μm. Preferably, the base layer has a thickness of 0.1 μm-9 μm.

[0047] In another embodiment, the thickness of the surface layer is formed to be 0.5 μm-55 μm, preferably 1 μm-35 μm.

[0048] In order to demonstrate the effect of varying the thickness of the base coating layer on the overall performance of the male terminal plug 101 and the female terminal socket 102, the inventors conducted a series of temperature rise and corrosion resistance time tests using samples of male terminal plug 101 and female terminal socket 102 made of the same specifications and materials but with different nickel-plated base layer thicknesses and the same silver-plated surface layer thicknesses, and the experimental results are shown in Table 2.

[0049] The temperature rise test in Table 2 was carried out as follows. The same current was passed through the inserted male terminal plug 101 and female terminal socket 102, and the temperatures at the same positions on the male terminal plug 101 and female terminal socket 102 were detected in a sealed environment before current was applied and after the temperature had stabilized. The difference was calculated and the absolute value was taken. In this example, a temperature rise exceeding 50 K was deemed to be a failure.

[0050] The corrosion resistance time test in Table 2 was conducted as follows: The male terminal plug 101 and female terminal socket 102 were placed in a salt spray test chamber, and salt water was sprayed at each position on the male terminal plug 101 and female terminal socket 102. Every 20 hours, they were removed and the surface corrosion was observed. This constitutes one cycle. When the corroded area on the surface of the male terminal plug 101 or female terminal socket 102 exceeded 10% of the total area, the test was stopped and the number of cycles was recorded. In this example, a test with fewer than 80 cycles was deemed to have failed.

[0051] [Table 2]

[0052] Referring to Table 2, it can be seen that when the thickness of the base nickel plating layer is less than 0.01 μm, the male terminal plug 101 and female terminal socket 102 pass the temperature rise test, but the coating layer is too thin, so the number of corrosion resistance cycles of the male terminal plug 101 and female terminal socket 102 is less than 80, which fails to meet the performance requirements of the male terminal plug 101 and female terminal socket 102. This significantly affects the overall performance and lifespan of the male terminal plug 101 and female terminal socket 102, and in severe cases, not only significantly shortens the product lifespan but also causes them to lose their effectiveness and may even cause a fire accident. When the thickness of the base nickel plating layer is more than 15 μm, the thick base coating layer is unable to dissipate heat from the male terminal plug 101 and female terminal socket 102, resulting in the male terminal plug 101 and female terminal socket 102 failing the temperature rise test. Furthermore, if the coating layer is too thick, it is more likely to detach from the surface of the male terminal plug 101 and female terminal socket 102, reducing the number of corrosion resistance cycles. Therefore, the inventors have formed the base layer coating layer to a thickness of 0.01 μm-15 μm. The inventors have found that when the base layer coating layer thickness is 0.1 μm-9 μm, the overall effects of temperature rise and corrosion resistance of male terminal plug 101 and female terminal socket 102 are better, so in order to improve the safety, reliability and practicality of the product itself, it is preferable to form the base layer coating layer to a thickness of 0.1 μm-9 μm.

[0053] In order to demonstrate the effect of the thickness of the surface coating layer on the overall performance of the male terminal plug 101 and the female terminal socket 102, the inventors conducted a series of temperature rise and corrosion resistance time tests using samples of the male terminal plug 101 and the female terminal socket 102 that were made of the same specifications and materials, had the same nickel-plated base layer thickness, and different silver-plated surface layer thicknesses, and the experimental results are shown in Table 3 below.

[0054] The experimental method was the same as that described above.

[0055] [Table 3]

[0056] Referring to Table 3, it can be seen that if the thickness of the silver plating layer on the surface layer is less than 0.5 μm, the male terminal plug 101 and female terminal socket 102 pass the temperature rise test, but the coating layer is too thin, so the number of corrosion resistance cycles of the male terminal plug 101 and female terminal socket 102 is less than 80, which fails to meet the performance requirements of the male terminal plug 101 and female terminal socket 102. This significantly affects the overall performance and lifespan of the male terminal plug 101 and female terminal socket 102, and in severe cases, not only significantly shortens the product lifespan but also causes the product to lose its effectiveness and lead to a fire accident. If the thickness of the silver plating layer on the surface layer is more than 55 μm, the thick coating layer on the surface layer is unable to dissipate heat from the male terminal plug 101 and female terminal socket 102, resulting in the male terminal plug 101 and female terminal socket 102 failing the temperature rise test. A thick coating layer is more likely to detach from the surface of the male terminal plug 101 and female terminal socket 102, reducing the number of corrosion resistance cycles. In addition, the metal used for the surface coating is expensive, and if a thick coating is used, the performance is not improved and there is no practical value. Therefore, the inventor forms the silver plating layer on the surface to a thickness of 0.1 μm-55 μm.

[0057] Preferably, the inventors have found that when the thickness of the surface coating layer is 1 μm-35 μm, the overall effects of the temperature rise and corrosion resistance of the male terminal plug 101 and the female terminal socket 102 are better, so in order to improve the safety, reliability and practicality of the product itself, it is preferable to form the thickness of the surface coating layer to 1 μm-35 μm.

[0058] In one embodiment, the conductor 111 and the input conductive contact 130 are electrically connected by crimping, welding, or integral molding, and the conductor 111 and the output conductive contact 140 are electrically connected by crimping, welding, or integral molding.

[0059] The crimping is performed by a manufacturing process in which the input conductive contact 130 or the output conductive contact 140 is attached to the conductor 111 and then crimped together using a crimping machine. The advantage of crimping is that it allows for mass production, and that products with stable quality can be mass-produced quickly using chain terminals and an automatic crimping machine.

[0060] The welding method includes one or more of a friction welding method, an ultrasonic welding method, an arc welding method, a laser welding method, and a resistance welding method.

[0061] Friction welding is a welding method that uses heat generated by friction between the contact surfaces of parts as a heat source to plastically deform the parts using pressure.

[0062] Ultrasonic welding refers to the process in which high-frequency vibration waves are transmitted to the surfaces of two objects that need to be welded, and the two surfaces rub against each other under pressure to form a fusion between molecular layers.

[0063] Arc welding refers to the use of an electric arc as a heat source and the physical phenomenon of air discharge to convert electrical energy into the thermal and mechanical energy required for welding to achieve the purpose of metal joining. The main methods include welding rod arc welding, submerged arc welding, and gas-shielded arc welding.

[0064] Laser welding is an efficient and precise welding method that uses a high-energy density laser beam as a heat source.

[0065] Resistance welding refers to a welding method that uses a strong current to generate heat due to contact resistance at the contact points between the electrode and the parts.

[0066] The integral molding method is a method in which the input conductive contact 130 or the output conductive contact 140 is formed directly on the conductor 111, eliminating the need for processing to connect the input conductive contact 130 or the output conductive contact 140 to the conductor 111, thereby reducing the processing steps and improving productivity.

[0067] As shown in FIG. 7, in one embodiment, the insulating portion 120 has a joining surface 121, and the insulating portions 120 of different wiring harness modules 100 can be connected by joining the joining surfaces 121 of the different wiring harness modules 100.

[0068] In this embodiment, not only are the conductors 111 of different wiring harness modules 100 connected via the input conductive contacts 130 and the output conductive contacts 140, but also the insulating parts 120 of different wiring harness modules 100 are connected, thereby firmly assembling the wiring harness modules and preventing them from easily coming apart, thereby improving the safety and reliability of the electrical connection.

[0069] As shown in FIG. 7, in the first embodiment, the insulating portion 120 has two end faces 104 facing each other along the longitudinal direction of the wiring harness module 100, and the intended joining surface 121 has at least one end face 104, that is, an end face of the wiring harness module 100 is joined to the insulating portion of another wiring harness module. For example, by joining the end faces of two wiring harness modules 100 and joining the wiring harness modules 100 front to back, the wiring harness is extended and a branch wiring harness of an assembled wiring harness is formed.

[0070] As shown in FIG. 12 , in the second embodiment, the insulating portion 120 has a side peripheral surface 105 provided along the circumferential direction of the wiring harness module 100, and the intended joining surface 121 includes at least a partial area of ​​the side peripheral surface 105. In other words, the side surface of the wiring harness module 100 is joined to the insulating portion of another wiring harness module. For example, by connecting the sides of two wiring harness modules 100, the wiring harness is expanded and the main wiring harness of the assembled wiring harness is formed by joining the wiring harness modules 100 side by side.

[0071] For example, as shown in Figures 1, 2, and 3, the insulating portion 120 is formed in the shape of a quadrangular prism, the insulating portion 120 has four side surfaces, and the intended joining surface 121 includes a partial area of ​​at least one of the side surfaces, for example, two, three, or four side surfaces; for example, the insulating portion 120 is formed in the shape of a triangular prism, the insulating portion 120 has three side surfaces, and the intended joining surface 121 includes at least a partial area of ​​at least one of the side surfaces, for example, two or three side surfaces.

[0072] Furthermore, in this embodiment, the side peripheral surface 105 of the insulating portion 120 includes a flat surface 106 (see Figure 3), and the intended joining surface 121 includes at least a portion of the flat surface 106, and / or the side peripheral surface 105 includes a curved surface 107 (see Figure 4), and the intended joining surface 121 includes at least a portion of the curved surface 107.

[0073] For example, when the insulating portion 120 is formed in a triangular or quadrangular prism shape, the side peripheral surface 105 forms a flat surface 106 (see Figure 3), and when the insulating portion 120 is formed in a cylindrical shape, the side peripheral surface 105 forms a curved surface 107 (see Figure 4).

[0074] The first and second embodiments may be implemented separately or in combination.

[0075] As shown in Figures 19 to 23, in one embodiment, a joining and fixing member 150 is provided on the intended joining surface 121 of the insulating part 120 or on a surface adjacent to the intended joining surface 121, and the intended joining surfaces 121 of different wiring harness modules 100 are fixed relatively to each other by the connection between each other's joining and fixing members 150. In other words, by fixing and connecting the insulating parts 120 of different wiring harness modules 100 with the joining and fixing members 150, it is possible to prevent them from becoming loose during use.

[0076] In one embodiment, the joining and fixing member 150 may be an adhesive layer, a magnetic attraction member, a plug connection member, a locking connection member, a bolt structure, a rivet structure, a welding member, a binding member, or a locking member.

[0078] In the second possible technical solution, the joining and fixing member 150 is made of a magnetic attraction member, which is arranged on the intended joining surface 121, and the intended joining surfaces 121 of different wiring harness modules 100 are attracted by the magnetic attraction member, allowing for easy connection, and is mainly applicable to environments where the assembly force required for the wiring harness modules is not high.

[0079] In a third possible technical solution, as shown in Figures 22 and 23, the joining and fixing member 150 is a plug-in connecting member, with a plug provided on one intended joining surface 121 and a socket provided on another intended joining surface 121, and the plug is inserted into and fixed in the socket, thereby fixedly connecting the intended joining surfaces 121 of different wiring harness modules 100.

[0080] In a fourth possible technical solution, the joining and fixing member 150 is a locking connecting member, and a hook member is provided on the intended joining surface 121. Another intended joining surface 121 is provided with a locking groove, and the hook member can be hooked into the locking groove to fix the intended joining surfaces 121 of different wiring harness modules 100.

[0081] In a fifth possible technical solution, the connecting and fixing member 150 is a bolt structure, which includes a bolt and a nut, the bolt is fixed to a target connecting surface 121, and the nut is rotatably mounted on another target connecting surface 121, or the nut is fixed to a target connecting surface 121, and the bolt is rotatably mounted on another target connecting surface 121, and when the bolt and the nut are screwed together and tightened, the target connecting surfaces 121 of different wiring harness modules 100 are fixedly connected. The bolt structure includes a bolt and a nut of at least M3, and the minimum torque when tightening the bolt structure is 0.2 Nm.

[0082] In a sixth possible technical solution, the joining and fixing member 150 has a rivet structure, including a rivet and a fixing hole, the fixing hole is provided on the two intended joining surfaces 121, the rivet passes through the fixing hole, one end of the rivet is passed through and deformed, and the fixing hole is pulled to fixedly connect the intended joining surfaces 121 of different wiring harness modules 100.

[0083] In a seventh possible technical solution, the joining and fixing member 150 is made of a welding member, which is provided on the two intended joining surfaces 121, and a welding machine is used to melt and connect the welding members, thereby fixedly connecting the intended joining surfaces 121 of different wiring harness modules 100. The welding machine includes a thermal welding machine and an ultrasonic welding machine.

[0084] In an eighth possible technical solution, the joining and fixing member 150 is made of a binding member, and a groove is formed on the intended joining surface 121. The binding member is used to bind the intended joining surfaces 121 at the groove position, thereby fixedly connecting the intended joining surfaces 121 of different wiring harness modules 100. The binding member can be a belt, a pipe clamp, a hook lock, etc. As shown in Figure 6, this technical solution is used when joining wiring harness modules side by side.

[0085] In a ninth possible technical solution, the joining fixing member 150 consists of a locking member, which is provided on an adjacent surface of the intended joining surface 121 (see Figures 19 to 21) or on the intended joining surface 121 (see Figures 22 to 23), and the intended joining surfaces 121 of different wiring harness modules 100 are locked and fixed by the locking member.

[0086] In one embodiment, the separation force exerted when the intended joining surface 121 separates after joining is at least 0.5 N. Since the assembly force required between the wiring harness modules 100 varies depending on the usage environment and the wiring harness module 100, the inventors have set the separation force exerted when the intended joining surface 121 separates after joining to at least 0.5 N in order to prevent different wiring harness modules 100 from being unnecessarily separated due to incorrect operation or vibration.

[0087] As shown in Figures 7 and 12, in one embodiment, the input conductive contacts 130 and the output conductive contacts 140 are arranged on the intended joining surface 121, i.e., the conductor connection portions and insulator connection portions of different wiring harness modules 100 are located in the same area, which further improves the reliability of the electrical connection and enables the joining operation of the wiring harness modules to be performed more quickly.

[0088] For example, if the input conductive contacts 130 and the output conductive contacts 140 are male terminal plugs 101 and female terminal sockets 102, respectively, the male terminal plugs 101 and the female terminal sockets 102 are both provided on the intended joining surfaces 121, and when joining two wiring harness modules 100, the male terminal plugs 101 and the female terminal sockets 102 of the two wiring harness modules 100 are inserted and connected, and at the same time, the intended joining surfaces 121 of the two wiring harness modules 100 are also brought into contact and fixed, simplifying the operation and improving assembly efficiency.

[0089] In one embodiment, the wiring harness module has a longitudinal direction, and the insulating portion 120 has two end faces 104 (see FIG. 5) facing each other in the longitudinal direction of the wiring harness module 100 and a side surface 105 (see FIG. 12) arranged in the circumferential direction of the wiring harness module 100, and at least one input conductive contact 130 is arranged on the end faces 104 or the side surfaces 105, and at least one output conductive contact 140 is arranged on the end face 104 or the side surface 105.

[0090] For example, the input conductive contacts 130 and the output conductive contacts 140 may be provided on the side surface 105 of the insulating part 120, or the input conductive contacts 130 may be provided on the side surface 105 of the insulating part 120 and the output conductive contacts 140 may be provided on an end surface of the insulating part 120, or the input conductive contacts 130 and the output conductive contacts 140 may be provided on two end surfaces of the insulating part 120, respectively, thereby realizing multiple different wiring harness module joining methods.

[0091] In one embodiment, the insulating portion 120 is made of a flexible material so that the wiring harness is flexible, such as one or more of polyvinyl chloride, polyurethane, nylon, polypropylene, silicone rubber, cross-linked polyolefin, synthetic rubber, polyurethane elastomer, cross-linked polyethylene, and polyethylene. In one embodiment, the insulating portion 120 is formed to cover the conductor portion 110 by one or more of an extrusion process, an injection process, a spray process, a plastic coating process, a slossi-molding process, an electrophoresis process, a braiding process, and a coiling process.

[0092] In one embodiment, the conductor 111 may be a solid wire, a multi-strand wire, a conductive foil, or a flat wire. When the wiring harness module 100 has a simple shape and a large current, a solid wire can be used as the conductor 111, which is not easily deformed and has a large conductive area, allowing a larger current to flow. When the wiring harness module 100 has a complex shape or requires frequent bending, a multi-strand wire can be used as the conductor 111, which is flexible, retractable, and not easily broken. When the wiring harness module 100 requires a small installation space or is installed in a confined environment, using a conductive foil or flat wire as the conductor 111 minimizes the height of the wiring harness module 100, facilitating installation, and facilitating heat dissipation of the conductor 111.

[0093] In one embodiment, the material of the conductor 111 may be one or more combinations of metals, conductive ceramics, carbon-containing conductors, solid electrolytes, mixed conductors, and conductive polymer materials.

[0094] In one embodiment, the material of the conductor 111 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. Preferably, the material of the conductor 111 is copper or a copper alloy, or aluminum or an aluminum alloy. Copper conductor materials have excellent conductivity and good elongation, making them desirable as cable conductor materials. However, as the price of copper continues to rise, the cost of using copper as a conductor material is becoming increasingly high. Therefore, it is necessary to find alternative materials to metallic copper to reduce costs. Metallic aluminum is present in the earth's crust at approximately 7.73%. With the optimization of refining technology, it is inexpensive. Compared to copper, aluminum is not only lighter, but also has comparable conductivity. Therefore, aluminum can partially replace copper in electrical connections. Therefore, it can be said that the development trend in the field of automotive electrical connections is to use aluminum instead of copper.

[0095] In other embodiments, other non-metallic materials can be used as the conductor 111, for example, graphene in carbon-containing conductors is also used as a good conductor material.

[0096] 18, in one embodiment, a wiring harness fixing member 160 is provided on the outer wall of the insulating part 120 and fixedly connected to a base that supports the wiring harness. For example, the wiring harness fixing member 160 fixes the wiring harness module 100 to an installation position, such as on the sheet metal of an automobile. For example, the wiring harness fixing member 160 is fixed to the installation position by a locking connection, a screw connection, or a plug connection method.

[0097] In one embodiment, the cross section of the wiring harness module 100 is circular, oval, rectangular, polygonal, E-shaped, F-shaped, H-shaped, K-shaped, L-shaped, T-shaped, U-shaped, V-shaped, W-shaped, X-shaped, Y-shaped, Z-shaped, semi-arc-shaped, arc-shaped, or wavy. The wiring harness module 100 can extend straight or curved along its length. By designing the end faces of the wiring harness module 100 in various shapes, those skilled in the art can select different shapes for the end faces of the wiring harness module 100 depending on the actual installation environment, thereby reducing the volume of the wiring harness module 100 and optimizing the installation environment of the wiring harness module 100, thereby improving the safety of the wiring harness module 100.

[0098] In one embodiment, a shielding layer, which may be a braided or foil-wrapped layer, is present on or within the insulating portion 120 of the wiring harness module 100. The shielding layer can reduce internal or external electromagnetic interference, ensure signal stability, and improve the stability of the wiring harness module 100.

[0099] As shown in Figures 2, 3, 5 and 12, an embodiment of the second aspect of the present application provides an assembled wiring harness, which is formed by joining a plurality of wiring harness modules 100 of the embodiment of the first aspect in a predetermined joining manner, and the conductors 111 of the plurality of wiring harness modules 100 are electrically connected to each other via input conductive contacts 130 and output conductive contacts 140, and the structures of the plurality of wiring harness modules 100 may be the same or different.

[0100] Other structures and effects of the assembly type wiring harness according to the embodiment of the second mode are similar to those of the wiring harness module 100 according to the embodiment of the first mode, and therefore overlapping descriptions will be omitted.

[0101] The assembled wiring harness of the present application is made up of interconnected wiring harness modules 100, making it easy to assemble and detach. During maintenance, it is only necessary to remove a damaged wiring harness module, eliminating the need to replace the entire wiring harness or group, thereby reducing manufacturing and maintenance costs.

[0102] The assembled wiring harness of the present application allows for modular manufacturing and customized assembly, which can increase production rates and improve yields.

[0103] In one embodiment, the predetermined joining method includes at least one of a horizontal joining method in which joining is performed along a horizontal direction perpendicular to the longitudinal direction of the wiring harness module 100, and a vertical joining method in which joining is performed along a vertical direction parallel to the longitudinal direction of the wiring harness module 100.

[0104] In one embodiment, the predetermined joining method includes a horizontal joining method and a vertical joining method, and the horizontal joining method is used to form a main wiring harness segment of the assembled wiring harness, and the vertical joining method is used to form a branch wiring harness segment of the assembled wiring harness.

[0105] As shown in FIG. 24, in one embodiment, the wiring harness module located at the outermost end of the assembled wiring harness is connected to an insertion system module 200 and inserted into the contact 300 of the electrical equipment through the insertion system module 200. Specifically, the insertion system module has a male system 201 and a female system 202. For example, the male system 201 is set on the outside of the corresponding wiring harness module 100, and the female system 202 is set on the outside of the contact 300 of the electrical equipment. When the female terminal socket 102 of the wiring harness module 100 and the male terminal 301 of the contact 300 of the electrical equipment are plugged in and connected, the male system 201 and the female system 202 are also plugged in and connected, thereby electrically connecting the assembled wiring harness and the electrical equipment.

[0106] Compared with the prior art, the assembled wiring harness of the present application has at least the following advantages: 1. The assembled wiring harness is made by joining wiring harness modules, which can be mass-produced and automated, resulting in high production rates and high yields. 2. Generally, when installing a wiring harness, many functional components must be installed in advance, which hinders the installation of subsequent wiring harnesses, wastes labor costs, and complicates the installation process. However, the assembly-type wiring harness of the present application installs wiring harness modules in order during installation, and installs the wiring harness while avoiding the pre-installed functional components, thereby easily installing the functional components, saving on-site assembly time and improving productivity. 3. If the wiring harness assembly is damaged, there is no need to replace the entire wiring harness, but only the damaged wiring harness module needs to be replaced directly, which saves maintenance time and reduces maintenance costs. 4. When there are many wiring harness circuits, wiring harness modules can be added in the diameter direction of the wiring harness to increase the number of wiring harness circuits, allowing for assembly in multiple ways, saving costs and reducing installation time. 5. Wiring harness modules can be designed and manufactured based on a shape modeled based on the installation and assembly positions, and can be directly installed according to the installation and assembly positions during final installation, saving installation time and reducing the number of parts required for installation. 6. The wiring harness module uses flexible conductors and insulators. If the mounting position of the wiring harness is displaced, the use of the flexible wiring harness module can reduce damage to the wiring harness caused by displacement of the mounting position, thereby improving the safety of the wiring harness. 7. By using the assembled wiring harness module, wiring harness modules in different physical areas can be replaced based on the wiring harness configuration. Since wiring harness modules in different physical mounting areas have the same circuit, they do not need to be replaced. This eliminates the need to re-manufacture the entire assembly of identical wiring harnesses with different functional configurations, thereby saving mass production resources and laying the foundation for wiring harness hardware.

[0107] Although the above has outlined specific embodiments of the present application, the scope of the present application is not limited thereto. Any equivalent modifications and amendments made by those skilled in the art without departing from the spirit and principles of the present application are within the scope of protection of the present application. The components of the present application are not limited to the above overall application, and the technical features described in the specification of the present application can be used separately or in multiple combinations according to actual needs. Therefore, all other combinations and specific applications of the points of the present invention should be construed as being included in the present application.
