A method of connecting stranded wire to a lead-frame bodyincludes the provision of a stranded wireIt is ensured that insulation is stripped from an endof the stranded wire. An electrically conductive lead-frame connection structureis associated with the lead-frame body. The endof the stranded wire is inserted into the lead-frame connection structureso that the lead-frame connection structure substantially surrounds the wire end. Solder flux is injected so as to be substantially about a portion of the end of the stranded wire. The lead-frame connection structure is placed in contact with a bottom resistance welding electrodeor a top resistance welding electrodeThe electrode that is not presently in contact with the lead-frame connection structure is moved so as to contact the lead-frame connection structure to resistance weld the wire endto the lead-frame connection structureand thereby define a solder crimp connectionof the wire end and the lead-frame connection structure.

A chokeis 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 coilsincluding two outermost coilsand. An attaching structureextends from one of the outermost coils and includes a loop structure. The loop structure is constructed and arranged to be inserted into a slotin a brush cardand moved into hooked relation with a retaining memberof 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 brushof a motor when the choke is secured to the brush card. An elongated end portionof 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 connectorwhen the choke is secured to the brush card.
