<p>PURPOSE: To connect a conductor to the terminal portion of a primary conductor without troublesome machining in a current transformer where a primary coil with four turns is constituted by four primary conductors. CONSTITUTION: One portion of a nut 51 is press-fit into and mounted to a through hole H provided at an edge part 13Al of a primary conductor 13A in a hair-pin shape. A connection conductor 25 is brought into contact with the edge part of the primary conductor 13A via a contact member 52 and a bolt 53 through a through hole (h) provided at the connection conductor 25 is screwed to the nut 51 for clamping. A contact plate with a number of contact parts in contact with the primary conductor 13 and the connection conductor 25 for continuity between both conductors and a plastic frame part for cutting the peripheral edge portion of the contact plate are provided at the contact member 52 and the connection part of both conductors is sealed by including them between both conductors 13A and 25 with the frame part compressed.</p> |
