Analysis of electromagnetic compatibility issues
Terminal Wire Harness Processing products may face a variety of electromagnetic compatibility issues during use. On the one hand, when current passes through the wiring harness, an electromagnetic field is generated. If the electromagnetic shielding performance of the wiring harness is poor, it may interfere with the surrounding electronic equipment and affect its normal operation. On the other hand, the external electromagnetic environment may also affect the Terminal Wire Harness Processing products, resulting in signal transmission errors or performance degradation. For example, in automotive electronic systems, if the terminal harness cannot effectively resist electromagnetic interference from components such as the engine, it may cause the control system of the car to malfunction and affect driving safety.
Solution to optimized design
During the design stage, electromagnetic compatibility issues should be fully considered. Use a reasonable wiring method to separate the wiring harnesses of different functions to avoid mutual interference between signals. At the same time, adding an electromagnetic shielding layer, such as wrapping the wiring harness with materials such as metal braided mesh or aluminum foil, can effectively block the propagation of electromagnetic fields. For some products with high requirements for electromagnetic compatibility, a filter circuit can also be designed to filter the signal in the harness, remove clutter and interference signals, and ensure the purity and stability of the signal.
Solution: Material selection
Choosing the right material is crucial to solving the electromagnetic compatibility problem. Materials with good electrical conductivity and magnetic permeability should be selected as terminals and wires to reduce electromagnetic radiation and conducted interference. For example, terminals made of copper alloy have good electrical conductivity and can effectively reduce resistance and electromagnetic interference caused by the passage of current. In addition, when selecting insulating materials, their electromagnetic barrier properties should also be considered. Selecting materials with lower dielectric constants can reduce the propagation loss of electromagnetic fields in the insulating layer.
Solution: Process control
During the processing process, strict process control is the key to ensuring electromagnetic compatibility performance. Ensure that the connection between the terminal and the wire is firm and reliable. When using the crimping process, control the crimping force and size to avoid increased contact resistance due to poor connection, thereby generating electromagnetic interference. At the same time, the shielding layer of the harness is well grounded to ensure that the shielding effect is fully utilized. During the entire processing process, attention should be paid to keeping the production environment clean to prevent impurities from mixing into the harness and affecting its electromagnetic performance. By optimizing the process, the consistency and stability of Terminal Wire Harness Processing products can be improved, thereby effectively solving the electromagnetic compatibility problem.
