Abstract:
A current detector for detecting or measuring an electric current, comprising:(a) a Hall-effect device for generating a voltage proportional to magnetic field strength; (b) two current path terminals for the inflow and outflow, respectively, of a current to be detected or measured; (c) a metal-made baseplate mechanically supporting the Hall-effect device, the baseplate being slitted to define a current path having a pair of opposite extremities connected respectively to the current path terminals, the current path being contiguous to the Hall-effect device for causing the same to generate a voltage proportional to the magnitude of a current flowing through the current path, the current path being formed in the shape of a U; and (d) the Hall-effect device having a primary working part for the development of the voltage proportional to the magnitude of the current flowing through the current path in the baseplate, the primary working part being substantially thoroughly contained within the U-shaped current path as seen in a direction normal to the baseplate.
