Abstract
A current detector comprising a Hall generator assembly and a current-path conductor assembly. The Hall generator assembly includes a Hall generator in the form of a semiconductor chip mounted to a metal-made mounting plate via a sheet of magnetic material such as Permalloy. A plastic encapsulation envelops at least parts of all the components of the Hall generator assembly. The current-path conductor assembly includes a sheet-metal current-path conductor and a plastic holder molded in one piece therewith. The Hall generator assembly and the current-path conductor assembly are combined by bonding together the encapsulation of the Hall generator assembly and the conductor holder of the current-path conductor assembly into a unitary casing for the current detector. A covering of Permalloy or the like envelopes the casing.
