Core advantages of crown spring terminals, stable contact without virtual connection: adopting a multi contact crown spring structure (gold-plated/nickel plated treatment), the contact area is more than 30% larger than ordinary terminals, the contact resistance is ≤ 5m Ω, and it has high elasticity, can withstand ± 1.5mm vibration offset, avoid virtual connection/signal interruption caused by equipment vibration and frequent insertion and extraction, and is suitable for industrial high-frequency operation scenarios.
