The invention discloses an electromagnetic interference suppression device, which relates to the technical field of vehicle filtering, and comprises two mutually independent clamping parts, and is characterized in that an unclosed accommodating space is formed between the two clamping parts and is used for accommodating two magnetic cores and a copper bar; and the copper bar is located between thetwo magnetic cores and penetrates through the accommodating space, and the clamping parts are used for fixing the multiple magnetic cores to the copper bar. The technical scheme of the invention hasthe beneficial effects that a plurality of magnetic cores can be arranged on one copper bar, the size of the clamping part is almost the same as that of the magnetic cores, the requirement on the sizeof a mounting space is not high, and the copper bar is very practical; and the clamping parts are made of a plastic material, and the insulating sheet is arranged between the two magnetic cores, so that electromagnetic interference can be effectively suppressed and reduced, the influence on a radio communication signal is reduced, the electromagnetic interference of an automobile during normal operation meets the requirements of the international standard CISPR25 and the national standard GB/T18655 of the automobile, and radio communication is protected.

    本发明公布了一种电磁干扰抑制装置,涉及车辆滤波技术领域,包括:两个相互独立的夹合部,两个所述夹合部之间形成不封闭的一容纳空间,所述容纳空间用于容纳两个磁芯和一铜排,且所述铜排位于两个所述磁芯之间并贯穿所述容纳空间,所述夹合部用于将多个所述磁芯固定在所述铜排上。本发明的技术方案的有益效果在于:能够在一个铜排上设置多个磁芯,夹合部的大小与磁芯的大小差不多,对安装空间的大小没有较大的要求,十分实用;夹合部使用塑料材质且在两个磁芯间设置绝缘片,能够有效地抑制降低电磁干扰,降低对无线电通讯信号影响,使得汽车在正常工作时的电磁干扰达到汽车国际标准CISPR25及国家标准GB/T18655要求,从而保护无线电通讯。
