[0002] EWIS (Electrical Wiring Interconnection System) refers to an electrical wiring interconnection system, and the EWIS refers to an electrical system in a vehicle such as an airplane, a train or an automobile, which covers a series of components such as cables, connectors, plugs, terminals, switches, fuses and power supplies. These components work together to connect and control various electrical devices and systems in the vehicle. With the rapid development of modern technology, the degree of systematization and integration of equipment is becoming higher and higher. This means that more functional modules need to be integrated in a limited physical space to meet the growing performance requirements and technical standards. This trend not only applies to consumer electronics such as smartphones and laptops, but also applies to industrial control equipment, medical equipment and aerospace fields.
