Embodiment 1

[0064] The invention provides a production method of a wire harness, such as figure 1 and figure 2 As shown, the production method of the wiring harness includes: step S10, preparing the substrate 10; step S20, spraying conductive paint onto the substrate 10 to form a conductive circuit 21; step S30, forming an insulating protective layer 40 around and on the surface of the conductive circuit 21 .

[0065] The production method of the wiring harness adopts the method of spraying to form a conductive loop 21 on the substrate 10. The conductive loop 21 can be connected with external electrical devices to realize the electrical connection function of the wiring harness; and the insulating protection layer 40 is used for insulation protection, thereby realizing the wiring harness. Circuit rapid prototyping. The production method of the wire harness adopts a spraying method to produce the wire harness, which has a high degree of flexible production, fast and convenient processin...

Embodiment 2

[0102] The present invention provides a nozzle 50, which is applied to the above wire harness production method, and the conductive paint is sprayed out through the nozzle 50. Adjusting the size or shape of the outlet 501 of the nozzle 50 can adjust the width and thickness of the section of the spraying conductive circuit 21 . Such as Figure 5 and Figure 6 As shown, the outlet 501 of the nozzle 50 is square. The discharge port 501 of the nozzle 50 is square, which is conducive to making the width and thickness of the cross section of the conductive circuit 21 uniform, ensuring the stability of the cross section, and avoiding more discharge in the middle of the cross section and less discharge in both sides during spraying. In the end, a conductive loop 21 with a cross section that is high in the middle and low on both sides is formed.

[0103] In one embodiment, the size of the discharge port 501 of the nozzle 50 is adjustable, so as to adjust the width and thickness of t...

Embodiment 3

[0106] The present invention provides a wire harness, which is produced by the above wire harness production method. The wire harness includes: a substrate 10, at least one conductive circuit 21 and at least one insulating protective layer 40, and each conductive circuit 21 is located between the substrate 10 and the outermost Between the insulating protection layers 40 of the layers, the conductive loops 21 and the insulating protection layers 40 are alternately distributed. The wire harness is suitable for flexible production and small-batch production, and has fast and convenient processing, high efficiency and reduced production cost.

[0107] In one embodiment, the section width of the conductive loop 21 is 0.1 mm-68 mm. In the wiring harness, the cross-sectional area of ​​the conductor determines the current that the conductor can conduct. Generally, the conductor that realizes the signal conduction has a small current and a small cross-sectional area. For example, the m...

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a production method of a wire harness, a nozzle and a wire harness. Background technique [0002] Electrical connections are made using wire harnesses. The existing wiring harness is mainly composed of parts such as electric wires, terminals, sheaths, positioning parts and brackets, and the parts are numerous and the structure is relatively complicated. The wires in the wiring harness need to be produced through processes such as conductor drawing, stranding, annealing, and extruding insulation layers. The production process is relatively complicated and the processing cost is relatively high. Most of the existing wiring harness production methods adopt the mode of centralized batch production. [0003] Some wire harness products with small batches and many types of products have high requirements for flexible production and cannot achieve mass production; such wi...
