What are the problem points that need to be paid attention to the processing of electronic wire harness? How to choose to design a good electronic wire harness?

Electronic wire harness processing is an important part of the electronic equipment manufacturing process, involving many aspects of electronic wire harness design, wiring, assembly and testing. The following are some of the issues that need attention and how to choose and design a good electronic harness recommendations.1. Demand analysis: Before designing an electronic harness, you need to conduct a demand analysis to clarify the function and performance requirements of the harness. Understand the electrical and mechanical characteristics of the equipment, determine the voltage, current, temperature and other operating conditions of the harness, as well as reliability, EMC (Electromagnetic Compatibility) and other requirements. 2. Wiring planning: According to the layout of the equipment and electrical connection requirements, the wiring of the electronic harness planning. Consider the length, shape, direction of the wire harness and the interaction with other components, reasonably determine the direction of the wire harness and the way to support, to avoid too long or too short wire harnesses, to reduce the interference between the wire harnesses. 3. material selection: select the appropriate conductor, insulating materials and protective casing and other materials. Wire should have good electrical conductivity and oxidation, corrosion resistance and other characteristics; insulating materials should have excellent insulating properties and high temperature performance; protective casing should have anti-stretch, flame retardant and other characteristics.4. Connection: according to the actual need to select the appropriate connection, such as welding, crimping, plugging and pulling connections. Consider the reliability, ease of maintenance and expandability of the connection.5. Dimensions and standards: Follow the relevant dimensions and standards, such as wire specifications and color coding, standards for connectors, etc. This helps to reduce incorrect connections and maintenance difficulties. This helps to reduce misconnections and maintenance difficulties, and ensures the interchangeability of the wire harness.6. Mechanical protection: Choose appropriate mechanical protection measures according to the working environment of the equipment, such as adding sheaths, protective tubes, etc., in order to prevent the wire harness from being mechanically damaged in the process of use.7. Electromagnetic compatibility (EMC): Consider electromagnetic interference and immunity to interference when designing the electronic wire harness. Reasonable arrangement of the harness to reduce mutual interference between the harnesses, and take shielding measures, such as the use of shielded wires, shielded bushings, etc., in order to improve the EMC performance of the system.8. Testing and verification: For a well-designed electronic wiring harnesses, it is necessary to carry out testing and verification to ensure that the quality and performance of the harnesses meet the requirements. Electrical testing, connectivity testing, EMC testing, etc. can be conducted.
