PROBLEM TO BE SOLVED: To provide a current transducer.SOLUTION: Current transducer includes a primary conductor bar (4) for carrying current to be measured, a magnetic core (6) comprising a magnetic circuit gap (22), a magnetic field sensor (8) comprising a circuit board (24) and a magnetic field detector positioned in the magnetic circuit gap, and an insulating housing (10) surrounding the magnetic core and magnetic field sensor. The primary conductor bar further includes a core passage section having a smaller width (W1) in comparison to the connection terminal ends (12a, 12b) extending outside of the housing, thereby providing an indent for the magnetic field detector to be positioned. The insulating housing includes a main housing portion (20) overmolded around the core passage section of the primary conductor bar, the main housing portion having a slot (44) configured to allow slidable insertion of the magnetic field sensor into the indent of the primary conductor bar for positioning in the magnetic circuit gap.SELECTED DRAWING: Figure 1a |
