In a complex electrical system, reasonable wiring and Terminal Harness layout are crucial to reducing signal attenuation and crosstalk.
First of all, in wiring planning, it should be classified according to signal type and frequency. For high-frequency signal lines, the routing length should be shortened as much as possible to reduce the signal propagation path, thereby reducing signal attenuation. At the same time, signal lines of different frequencies and types should be kept at a certain distance to avoid capacitive coupling and inductive coupling caused by being close to each other, so as to reduce crosstalk.
In terms of Terminal Harness layout, the use of shielded wires is an effective method. Wrapping the key signal lines in the shielding layer can effectively block the interference of external electromagnetic fields and prevent internal signals from generating external radiation interference. In addition, the position and direction of the terminals should be reasonably arranged to keep uniform spacing between signal harnesses, avoid excessive crossing and winding of harnesses, and reduce mutual interference between signals.
In the design of line direction, loops should be avoided as much as possible. Loops will cause electromagnetic signals to form circulation in them, increase electromagnetic radiation and induction, and cause signal distortion and crosstalk. At the same time, it is also an important measure to reduce crosstalk and signal attenuation by arranging strong and weak current lines separately and reducing the electromagnetic interference of strong current lines on weak current signal lines.
In addition, choosing the right wiring material is also very critical. The use of low resistance, low capacitance and low inductance wire materials can reduce the energy loss and distortion of signals during transmission, thereby reducing signal attenuation. In addition, providing good fixation and support for the wiring harness to prevent poor contact and line deformation caused by vibration, pulling and other factors will help maintain the stability of signal transmission.
In summary, through scientific wiring planning, reasonable Terminal Harness layout, appropriate shielding measures, line direction design and material selection, signal attenuation and crosstalk can be effectively reduced in complex electrical systems, and the performance and reliability of the system can be improved.
