Abstract

一种触头装置、电磁开关、车载充电机及新能源汽车。触头装置(100)包括基体(10)、两个静触头(30)及动触头组件(50)，所述基体(10)具内腔(101)，两个所述静触头(30)间隔固定于所述基体(10)上并伸入所述基体(10)的内腔(101)，所述动触头组件(50)包括推动部件(51)与动触头(52)，所述推动部件(51)活动穿设于所述基体(10)，所述动触头(52)安装于所述推动部件(51)上并位于所述基体(10)的内腔(101)，所述推动部件(51)用于带动所述动触头(52)运动，以实现所述动触头(52)与两个所述静触头(30)接触或分离，其中，所述动触头(52)包括N个并联的触头片(521)，所述N为大于1的整数。如此，降低了动触头(52)经受短路大电流时被斥开的可能性，提高了触头装置与电磁开关的短路耐受能力。
