PURPOSE:To prevent incoming of noise from an earthing circuit or emit noise from the earthing circuit to give bad effects to surrounding electric circuits by installing electromagnetic interference (EMI) countermeasure members of ferrite cores or the like at important parts of the earthing circuit of a connector. CONSTITUTION:Electromagnetic interference (EMI) countermeasure parts are electrically or electromagnetically connected with a part of an earthing circuit. This EMI countermeasure electric connector comprises an insulating housing 10, a plurality of contacts 20, a shield case 30, earthing EMI countermeasure parts of earthing ferrite core plates 40A, 40B, and a signal EMI countermeasure part of a signal ferrite core plate 50 mainly. Incoming of noise from the earthing circuit to give bad effects to electric circuits of the set or the like, or emission of noise from the earthing circuit to give bad effects to surrounding electric circuits can be thus be prevented. |
