    • A choke 20 is provided for suppressing radio-frequency interference of a brush-type motor. The choke includes a single wire having a portion wound about a coil axis A to define a plurality of coils 24 including two outermost coils 26 and 28. An attaching structure 30 extends from one of the outermost coils and includes a loop structure 42. The loop structure is constructed and arranged to be inserted into a slot 58 in a brush card 48 and moved into hooked relation with a retaining member 60 of the brush card that is associated with the slot so as secure the choke to the brush card. At least a portion of the attaching structure is constructed and arranged to be in electrical connection with a brush 56 of a motor when the choke is secured to the brush card. An elongated end portion 44 of the choke extends directly from the other of the outermost coils. The elongated end portion is constructed and arranged to be directly electrically connected to an electrical connector 54 when the choke is secured to the brush card.
    • 提供了一种用于抑制刷式电动机的射频干扰的扼流圈20。 扼流器包括单线,其具有围绕线圈轴线A缠绕的部分,以限定包括两个最外侧线圈26和28的多个线圈24。 附接结构30从最外面的一个线圈延伸并且包括环形结构42。 环形结构被构造和布置成插入到刷卡48中的槽58中并且与与槽相关联的刷卡的保持构件60移动成钩状关系,以将扼流圈固定到刷卡。 连接结构的至少一部分被构造和布置成当扼流器固定到电刷卡时与电动机的电刷56电连接。 扼流器的细长端部44直接从最外面的线圈中的另一个延伸。 细长端部构造和布置成当扼流器固定到刷卡时直接电连接到电连接器54。
