Introduction: The Ubiquitous "Electronic Circulatory System"
In modern electronic devices, electronic & electrical wire harnesses serve as the vascular system, performing dual missions of power transmission and signal communication. Statistics show that a premium smartphone contains up to 1.2 meters of internal wiring, while industrial robots may utilize over 200 sets of different specification harnesses. With 5G and IoT advancements, the global electronic wire harness market is projected to exceed $42 billion by 2025.
