Abstract
A toroidal coil is wound around a donut-shaped ferrite core through which passes one or more conductors for detecting a high current pulse within the conductors. An interface block includes a generally circular recessed upper portion for receiving the toroidal coil/ferrite core combination and further includes a pair of aligned, spaced slots extending between the upper and lower surfaces and within the recessed upper portion of the block. Each of the conductors is in the form of a strip-like metal conductor and is disposed within and along the length of a respective slot in the interface block. The upper end of each strip-like conductor is adapted for mounting to an upper portion of the interface block and coupling to a respective first lead by means of a first mounting screw. Similarly, the lower end of each strip-like conductor is adapted for mounting to a lower portion of the interface block and coupling to a respective second lead by means of a second mounting screw. The ends of the toroidal coil are positioned within a respective groove in a lateral portion of the interface block and extend to the lower surface thereof where they are connected to respective terminal pins for coupling the toroidal pick-up coil to appropriate circuitry on a printed circuit board.
