▎ 摘　　要

NOVELTY - The method involves preparing (S10) a printing plate. The substrate is prepared (S20). The conductive ink is printed (S30) onto the substrate through the printing plate. The conductive ink is condensed (S40) to form a conductive loop. An insulating protective layer is formed (S50) around and on the surface of the conductive loop. USE - Method for producing wire harness such as space wire harness (all claimed) suitable for mounting conditions, convenient for application to installation environment complex of electric appliance, vehicle, household appliance, used in technical field of electronic component such as vehicle structure component or vehicle mounted electric appliance component. ADVANTAGE - The forming efficiency of the conductive circuit is improved such that the automation, mass production and rapid production can be realized, and the degree of production automation is relatively high. The technical problems of the wiring harness for electrically connecting the electrical devices, the complicated production process and the high processing cost are alleviated. The printing plate is prepared in advance. The wiring harness is easy to install and disassemble. The multi-layer printing can be used, and more conductive circuits can be prepared under the condition of a small substrate area to meet the requirements of more electrical circuits. The method of perforating and pouring conductive materials can be used to electrically connect the conductive loops of different layers to achieve a more complex electrical circuit design scheme, and can be applied to more complex wiring harnesses. The choice of materials for the insulation protection layer is relatively diverse, and various processes can be used to achieve insulation protection to ensure the insulation protection effect. The integrated production of components and wiring harnesses can be realized, and the rapid installation and disassembly of the wiring harness can be realized. The application environment of the wire harness is increased. The flexible substrates can be used so that the wire harness can be applied to a variety of installation situations. The produced wire harness can be applied to electrical appliances with complex installation environments, and can be used in environments with high vibration requirements to reduce the interference of vibration factors. The damaged substrate can be replaced directly without the need to dismantle and replace the entire wiring harness when the wiring harness is damaged such that the maintenance man-hours can be saved and the maintenance costs can be reduced. The conductive ink is made of metal powder or other conductive powder, is simple and convenient to prepare, and has good conductivity and little pollution. The shielding layer is set outside the wiring harness, and can be located at a position where electromagnetic interference is relatively strong so that the signal in the wiring harness can shield the electromagnetic interference and ensure the stability of the signal. The heat sink is arranged on the insulating protective layer to quickly dissipate the heat generated by the wire harness current into the air, to reduce the temperature of the wire harness and to reduce the risk of fusing of the conductive circuit. The equipment cost is relatively low such that the cost of the wiring harness is reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for: (1) a wiring harness.
