<p>A current detector for detecting or measuring an electric current, comprising a Hall-effect device (1) for generating a voltage proportional to magnetic field strength, a metal-made baseplate (2, 2a-2e) mechanically supporting the Hall-effect device, and two current path terminals (3 and 4) for the inflow and outflow, respectively, of a current to be detected or measured. For handling a current of greater magnitude than a comparable prior art device, the baseplate is slitted to delimit an elongate path (34, 34a-34e) along which the current is to flow. The current path extends contiguous to the primary working part (23) of the Hall-effect device for causing the same to generate a voltage proportional to the magnitude of the current. The pair of opposite extremities of the current path are connected respectively to the current path terminals (3 and 4). <IMAGE></p> |
