One end of the outlet terminals has a style corresponding with the leading-out
ends of the kilowatt-hour meter, and the other end has a style corresponding with
the connecting terminals inside the kilowatt-hour meter. A plunger magnetic
pole structure for a relay includes a magnetic yoke ( 19 ), an armature ( 20 ), at
least one magnetic pole ( 18,23 ) and at least one coil ( 16 ), wherein the magnetic
pole ( 18,23 ) is fixed, and the armature ( 20 ) is connected with a connecting link
