接触片

一种精密加工的金属部件，位于电机接线盒内，用于在电源电缆和电机绕组之间建立可靠、低电阻的电气连接。它是电流传输的主要接口，确保稳定的电气连续性，同时适应运行过程中的热膨胀和机械应力。

基于导电接触压力的原理：当接线螺钉拧紧时，接触片对导体施加均匀压力，形成大面积接触，从而最大限度地降低电阻并防止电弧。通过弹簧特性或刚性夹紧力保持稳定的导电性。

Operates on the principle of conductive contact pressure: when secured by terminal screws, the contact plate applies uniform pressure against conductors, creating a large surface area contact that minimizes electrical resistance and prevents arcing. It maintains consistent conductivity through spring-like properties or rigid clamping force.
