Abstract
A connector structure for a brush motor includes a connector body 10 associated with the motor, an X2Y capacitor structure 20, a positive power terminal connection structure 14 associated, a negative power terminal connection structure 14′ and a ground connection structure 16. The positive power terminal connection structure is electrically connected with the capacitor structure and is constructed and arranged to electrically engage a positive power terminal 18 of the motor. The negative power terminal connection structure 14′ is electrically connected with the capacitor structure and is constructed and arranged to electrically engage a negative power terminal of the motor. The ground connection structure 16 is electrically connected with the capacitor structure and is constructed and arranged to be electrically connected with a ground mass. The X2Y capacitor structure provides RFI suppression.
