    • An electronic device with an electrostatic guiding structure includes a metal case, a plastic case overlapping the metal case, a conductive strip, and an electrically insulating strip. The conductive strip is electrically connected to a conductive region of the plastic case, and has at least one tip portion. An end point of the tip portion is located at an edge of the electrically insulating strip, and separated from the metal case with the electrically insulating strip. The conductive region is electrically connected to a ground region of an electronic module. Therefore, when electrostatic charges accumulated in the metal case is above a specific value, the electrostatic charges are discharged to the ground region of the electronic module according to point discharge principle, thereby protecting user of the electronic device from getting an electric shock.
    • 具有静电引导结构的电子设备包括金属外壳,与金属外壳重叠的塑料外壳,导电条和电绝缘条。 导电带电连接到塑料外壳的导电区域,并具有至少一个尖端部分。 尖端部分的端点位于电绝缘条的边缘处,并且与电绝缘条与金属壳分离。 导电区域电连接到电子模块的接地区域。 因此,当金属壳体中累积的静电电荷高于特定值时,根据点放电原理将静电电荷排出到电子模块的接地区域,从而保护电子设备的用户免受电击。
